+SWFOC DLL Bridge — Comprehensive Test Suite
+=============================================
+Connects to the swfoc_bridge named pipe and exercises every SWFOC_*
+function registered in lua_bridge.cpp (12 functions total).
+
+Tests:
+  - Valid invocation of each function
+  - Invalid argument handling for each function
+  - Read-set-read cycles for setters (Credits, TechLevel)
+  - SWFOC_StateInfo() (v3 game state cache)
+  - Stress test: 100 rapid commands
+  - Timeout test: 2s deadline
+  - Produces bridge_test_report.json
+
+Usage:  python bridge_test.py
+        python bridge_test.py --stress-count 200

+# Bridge v3 Changes: Game State Caching
+
+## Problem
+
+The DLL bridge hooks `luaD_call`, which fires on every Lua function invocation across 400+ Lua states. To execute pipe commands on the correct state (one with game globals like `Find_Object_Type`), the v2 bridge probed the Lua stack during every `luaD_call` invocation when a pipe command was pending. This was unreliable because:
+
+1. The stack may be in a transient state during `luaD_call` (mid-call setup), making the probe unsafe.
+2. Probing involves `pushstring` + `gettable` + `type` + `settop` on a potentially unstable stack, risking heap corruption.
+3. The probe ran on every `luaD_call` while a command was pending, adding overhead to a hot path.
+
+## Solution: Cache game states at creation time
+
+Instead of probing the stack on every `luaD_call`, we identify game states once during `lua_open` and cache their pointers. The `luaD_call` hook then does a simple pointer lookup (O(n) on a tiny vector, typically 1-3 entries) instead of touching the Lua stack.
+
+## Files Changed
+
+### `lua_bridge.cpp`
+
+**A. New includes and globals (top of file):**
+- Added `<string>`, `<vector>`, `<algorithm>` includes.
+- Added `CRITICAL_SECTION csGameStates` and `std::vector<void*> cached_game_states` for the cache.
+
+**B. New hook types:**
+- Added `lua_close_t` typedef and `orig_lua_close` trampoline pointer for the lua_close hook.
+
+**C. New function: `SWFOC_StateInfo()` (line ~465):**
+- Lua-callable function returning a string listing all cached game state pointers.
+- Useful for debugging: call `print(SWFOC_StateInfo())` from the game console or pipe.
+
+**D. New function: `Hook_lua_close()` (line ~484):**
+- Intercepts `lua_close` to remove destroyed states from `cached_game_states`.
+- Prevents stale pointers from accumulating in the cache.
+- Thread-safe via `csGameStates` critical section.
+
+**E. Modified: `Hook_luaD_call()` (line ~537):**
+- **REMOVED**: Stack probing logic (`pushstring("Find_Object_Type")` + `gettable` + `type` check).
+- **REPLACED WITH**: `std::find` lookup in `cached_game_states` under `csGameStates` lock.
+- No Lua stack manipulation during `luaD_call` anymore -- just a pointer comparison.
+
+**F. Modified: `Hook_lua_open()` (line ~749):**
+- After registering SWFOC_* functions and running self-tests, probes for `Find_Object_Type` in the global table.
+- If found (meaning this is a gameplay state, not a menu/config state), adds `L` to `cached_game_states`.
+- This is safe because `lua_open` returns a fully initialized state with a stable stack.
+
+**G. Modified: `Hook_lua_open()` function registration (line ~630):**
+- Added `SWFOC_StateInfo` registration alongside other SWFOC_* functions.
+- Function count bumped from 11 to 12.
+
+**H. Modified: `RegisterAll()` (line ~499):**
+- Added `SWFOC_StateInfo` to the registration table.
+
+**I. Modified: `LuaBridge_Init()` (line ~828):**
+- `InitializeCriticalSection(&csGameStates)` called before MinHook initialization.
+- New `lua_close` hook installed after `lua_open` hook, before `luaD_call` hook.
+- `lua_close` hook failure is non-fatal (logged as WARNING) since the RVA is estimated.
+
+**J. Modified: `LuaBridge_Shutdown()` (line ~902):**
+- Clears `cached_game_states` vector and destroys `csGameStates` critical section.
+
+### `rvas.h`
+
+- Added `lua_close = 0x7B8A70` with `ESTIMATED` / `NEEDS_VERIFICATION` marker.
+- Address is between `lua_open` (0x7B8930) and `lua_checkstack` (0x7B8BC0), consistent with Lua 5.0.2 source layout.
+
+## Action Required
+
+The `lua_close` RVA (0x7B8A70) is an estimate based on source ordering. It needs Ghidra verification before the hook can be considered reliable. If the hook fails at runtime, the bridge logs a warning but continues functioning -- the only consequence is that stale cache entries may accumulate (harmless since the game typically doesn't destroy gameplay states during a session).
+
+To verify: open StarWarsG.exe in Ghidra, navigate to 0x1407B8A70 (image base + RVA), and confirm it matches the `lua_close` signature: single parameter (lua_State*), calls `luaC_callGCTM` and `luai_close`, frees the state.
+
+## Performance Impact
+
+- **Hot path (`luaD_call`)**: Replaced 5 Lua C API calls (pushstring, gettable, type, settop, gettop) with one `EnterCriticalSection` + `std::find` on a 1-3 element vector + `LeaveCriticalSection`. Significantly cheaper and does not touch the Lua stack.
+- **Cold path (`lua_open`)**: Added one probe per state creation (same 5 API calls that were removed from the hot path). This runs once per state, not per function call.
+- **Memory**: One `void*` per game state in the cache vector (typically 1-3 entries, 8-24 bytes total).

+# SWFOC Editor + Bridge — User Workflow
+
+**Audience:** Someone who hasn't touched the stack in a week.
+**Goal:** Go from "game is not running, editor is not open" to "I can
+click buttons in the editor and observe changes in my live SWFOC game."
+
+This doc is deliberately concrete — every command, every path, every
+status indicator. If something in here doesn't match what you see on
+screen, the stack has drifted and you should stop and diagnose before
+pushing further.
+
+---
+
+## Cold start (first session after a break)
+
+### 0. Prerequisites (one-time, verify once per machine)
+
+- **Game installed** at `D:\SteamLibrary\steamapps\common\Star Wars Empire at War\corruption\` with `StarWarsG.exe` present. If Steam put it somewhere else, update `.claude\ida-pro-mcp.local.md`'s `expected_idb_path` first.
+- **MinGW-w64** on `PATH` (`x86_64-w64-mingw32-g++ --version` should work) — used only if you need to rebuild the bridge C++ code.
+- **.NET 8 SDK** on `PATH` (`dotnet --version` should show `8.x`) — used to build and run the editor.
+- **Python 3** on `PATH` (`python --version` should show `3.x`) — used to lint the ledger and generate synthetic snapshots.
+
+### 1. Verify the bridge is ready (before starting the game)
+
+The bridge ships as `swfoc_lua_bridge\powrprof.dll`. It replaces the
+Windows stock `powrprof.dll` via DLL hijack, so it must be pre-deployed
+into the game's directory BEFORE the game launches.
+
+```powershell
+# Compare source vs deployed SHA256
+certutil -hashfile "C:\Users\Prekzursil\Downloads\swfoc_memory\swfoc_lua_bridge\powrprof.dll" SHA256
+certutil -hashfile "D:\SteamLibrary\steamapps\common\Star Wars Empire at War\corruption\powrprof.dll" SHA256
+```
+
+- **If the two SHAs match** → the deployed DLL is current; skip to Step 2.
+- **If they differ** → the deployed DLL is stale. Back up the deployed copy, then copy the source version over:
+
+```powershell
+cd "D:\SteamLibrary\steamapps\common\Star Wars Empire at War\corruption"
+Copy-Item powrprof.dll powrprof.dll.backup-$(Get-Date -Format yyyy-MM-dd)
+Copy-Item "C:\Users\Prekzursil\Downloads\swfoc_memory\swfoc_lua_bridge\powrprof.dll" .
+```
+
+> ⚠️ **Current state as of 2026-04-09**: the source DLL is 3 days newer
+> than the deployed copy. You WILL need to deploy before the first live
+> test — see `knowledge-base/handoff_2026-04-09.md` Section 7 for the
+> full context.
+
+### 2. Rebuild the bridge (only if source has changed)
+
+```powershell
+cd "C:\Users\Prekzursil\Downloads\swfoc_memory\swfoc_lua_bridge"
+.\build.bat
+```
+
+Expected final output:
+```
+=== ALL BUILDS AND TESTS PASSED ===
+```
+plus `bridge_test_harness.exe` reports `=== Results: 295 passed, 0 failed ===`
+and `powrprof.dll` is regenerated in this directory.
+
+### 3. Launch the editor
+
+```powershell
+cd "C:\Users\Prekzursil\Downloads\SWFOC editor"
+dotnet build                                       # incremental; must show "0 Warning(s), 0 Error(s)"
+# Then either run from Visual Studio, or:
+.\src\SwfocTrainer.App\bin\Debug\net8.0-windows\SwfocTrainer.App.exe
+```
+
+The editor is a WPF app. On first launch it will:
+- Scan for installed SWFOC profiles
+- NOT attach to the game (deliberate — it waits until you attach manually)
+
+### 4. Launch the game
+
+Start SWFOC from Steam like normal. Wait until you're on the main menu.
+
+### 5. Attach
+
+In the editor, click the **Attach** button (top of Runtime tab). Status
+should change from "Detached" to "Attached to StarWarsG.exe (PID #####)".
+
+### 6. Verify the bridge is live
+
+Click the **Ping Bridge** or equivalent diagnostic button. The status
+indicator should show:
+- **Green / "Bridge v1.0 (or newer) connected"** — you're good to go.
+- **Red / "Pipe not found"** — the DLL didn't load. The game is running the stock `powrprof.dll` from `C:\Windows\System32\` instead of our proxy. Diagnose:
+  1. Check that `D:\...\corruption\powrprof.dll` is our version (SHA compare from Step 1)
+  2. Check Windows Event Viewer for DLL load errors
+  3. Restart the game
+
+- **Red / "Bridge version mismatch"** — the deployed DLL is older than the editor expects. Redeploy and restart the game.
+
+---
+
+## The happy path
+
+*"I want to god-mode my Vengeance Frigate in a tactical battle."*
+
+### Step 1 — Enter a tactical battle
+
+Start a skirmish (or load a save) and get into tactical combat. Make
+sure your Vengeance Frigate is present and selectable.
+
+### Step 2 — Find its object address
+
+The editor's **Diagnostics** tab has a "Unit Inspector" section with an
+"Address" text box and an "Inspect" button. But you need to know the
+object address first. Two options:
+
+- **Option A (manual)**: open Cheat Engine, attach to `StarWarsG.exe`, find your frigate via unit list scan, copy the `this` pointer hex value.
+- **Option B (future)**: `SWFOC_FindSelectedUnit()` helper (doesn't exist yet — TODO item for next session).
+
+### Step 3 — Inspect to confirm
+
+Paste the hex address (without `0x`, as decimal or prefixed hex) into
+the Unit Inspector box and click **Inspect**. Expected response:
+
+```
+hull=<current>/<max>  owner=<slot>  obj_id=<id>  parent_idx=0xFF  status_flags=0x00  prevent_death=0x00  invuln_flag=0x00  hardpoint_flag=0xFF  components_ptr=0x<address>
+```
+
+If `parent_idx` is `0xFF`, you've selected the root unit (good — frigates
+are roots, hardpoints are children). If it's anything else, you selected
+a hardpoint and need to walk up.
+
+### Step 4 — Enable god mode
+
+Click the **God Mode** toggle button (Combat tab, or Bridge Helpers tab
+depending on the editor version). Expected editor status: `"god mode
+enabled"`. In-game verification:
+
+- Let an enemy shoot your frigate
+- HP should NOT decrease (enemy damage is blocked)
+- If you order the frigate to take damage (repair hack, friendly fire), HP
+  also doesn't decrease
+
+The underlying mechanism is the `SetHP` MinHook detour — it intercepts
+every call to the HP-write function, walks the parent chain via
+`obj+0x335 ParentIdx` and `obj+0x278 Components`, checks `owner == local
+player`, and if yes, bails out of the write entirely.
+
+**Hardpoints propagate automatically** — the hook walks the parent chain
+so damage to a hardpoint also fails the check and gets blocked. You do
+NOT need to individually enable god mode per hardpoint.
+
+### Step 5 — Turn it off
+
+Click the **God Mode** toggle again (or its "Disable" pair if the UI has
+separate buttons). Expected status: `"god mode disabled"`. The MinHook
+detour is removed, and subsequent damage calls pass through unchanged.
+
+### Step 6 — Detach cleanly before quitting
+
+Before closing the game, click **Detach** in the editor. This releases
+the named pipe and lets the bridge's pipe thread exit gracefully. If you
+close the game without detaching, the editor will show
+"Pipe disconnected" and may need a restart before the next attach.
+
+---
+
+## Troubleshooting
+
+### 1. Editor shows "bridge not connected"
+
+**Symptom:** Status indicator red, all bridge calls fail with "pipe
+not found" or "ConnectNamedPipe failed (error 2)".
+
+**Root cause:** One of:
+- The deployed `powrprof.dll` is the stock Windows one, not ours
+- Our DLL is deployed but the game hasn't loaded it yet (check whether
+  the game is actually running and fully initialized)
+- A previous session left the pipe in a weird state
+
+**Fix:**
+```powershell
+# Verify deployment
+certutil -hashfile "D:\SteamLibrary\steamapps\common\Star Wars Empire at War\corruption\powrprof.dll" SHA256
+
+# Compare with source
+certutil -hashfile "C:\Users\Prekzursil\Downloads\swfoc_memory\swfoc_lua_bridge\powrprof.dll" SHA256
+
+# Kill any stray replay binaries that might be holding the pipe name
+Stop-Process -Name swfoc_replay -Force -ErrorAction SilentlyContinue
+
+# Restart the game from scratch (Steam -> exit game -> relaunch)
+```
+
+### 2. Bridge connects but commands silently no-op
+
+**Symptom:** Status says "Bridge v1.0 connected", commands return `"OK"` or `"1"`, but the expected in-game effect doesn't happen.
+
+**Root cause:** The deployed DLL is older than the helper the editor is
+calling. For example, the editor calls `SWFOC_SetCreditsForSlot(0, 50000)`
+but the old deployed DLL only knows `SWFOC_SetCredits(amount)`, so the
+Lua interpreter returns `nil` for the unknown function name and the
+wrapper silently no-ops.
+
+**Fix:** Compare SHA256 as in #1. If they differ, redeploy the bridge.
+Watch for the version string: a stale bridge will still return
+`"SWFOC Lua Bridge v1.0"` so the version string alone isn't enough — the
+SHA is the authoritative drift check. After redeploy, restart the game.
+
+**Preventive:** Bump the version string in `lua_bridge.cpp::Lua_GetVersion`
+every time you add a SWFOC_* helper so drift becomes visible from the
+editor's status bar.
+
+### 3. Stray `swfoc_replay.exe` blocks the pipe with error 231
+
+**Symptom:** Log shows `[Replay] CreateNamedPipe failed: 231` or
+`ERROR_PIPE_BUSY`. The editor can connect via the LIVE bridge pipe
+(`\\.\pipe\swfoc_bridge`) but the REPLAY mirror pipe
+(`\\.\pipe\swfoc_bridge_replay`) is stuck.
+
+**Root cause:** A previous test run left `swfoc_replay.exe` alive with
+an open pipe. Windows doesn't release the pipe name until the process
+dies.
+
+**Fix:**
+```powershell
+Stop-Process -Name swfoc_replay -Force -ErrorAction SilentlyContinue
+# Verify it's gone:
+Get-Process swfoc_replay -ErrorAction SilentlyContinue
+```
+
+### 4. Feature works in replay tests but not in the live game
+
+**Symptom:** `FullFeatureSmokeTest` passes 14/14 in the replay harness,
+but when you click the button in the live editor the in-game effect
+doesn't happen.
+
+**Root cause:** The replay binary is a PARALLEL UNIVERSE — it accepts
+the same pipe protocol as the live bridge but its underlying state
+manipulation is done against `fake_memory.cpp` stubs, not the real game.
+Specifically, the replay's `fake_lua` cannot execute arbitrary Lua
+method calls like `p1:Make_Ally(p2)` — it short-circuits a small table
+of known `SWFOC_*` helpers and returns canned responses for everything
+else. So a service that EMITS non-SWFOC_* Lua (DiplomacyService,
+CooldownManagerService, etc.) will "pass" the replay smoke test
+(command accepted) but do nothing in the live game unless the live
+game's Lua interpreter actually has the `Make_Ally` wrapper registered.
+
+**Diagnosis:**
+- Open `lua_bridge.cpp` and check whether the service's `BuildLuaCommand`
+  output contains a `SWFOC_*` helper from the registration table.
+- If yes → the live bridge will execute it. Problem is elsewhere
+  (memory offset, argument type, etc.).
+- If no → the service is calling a game-side Lua function. Check the
+  verified_facts.json ledger to confirm it actually exists as a Lua
+  binding in the real game. If it's documented but still fails, the
+  binding may be scoped to a specific game mode (tactical vs galactic).
+
+**Fix:** depends on the specific service. See
+`knowledge-base/v5_service_fixes_applied.md` for the canonical list of
+service fixes and their Lua command shapes. If a service needs a fix,
+add a row to that file AND add a regression guard pair in
+`tests/SwfocTrainer.Tests/Regression/`.
+
+### 5. Game crashes when a feature is toggled
+
+**Symptom:** Clicking a button (especially God Mode or Inspect) causes
+the game to immediately CTD (crash-to-desktop) or hang.
+
+**Root cause:** The bridge DLL installed a MinHook detour that is
+reading or writing an invalid memory address. This is almost always
+because:
+- A struct field offset is wrong (e.g. `GameObject+0x5C HP` is
+  actually different in this build of SWFOC)
+- The MinHook target RVA is wrong (the detour installed at
+  `base + 0x3A89D0` intercepts a different function than expected)
+- The hook is installed at the right RVA but the surrounding bytes were
+  patched by a game update
+
+**Fix:**
+1. IMMEDIATELY disable the bridge: close the editor (pipe disconnects),
+   then close the game. Restart the game WITHOUT attaching.
+2. If the game still crashes on startup, swap the deployed DLL back to
+   the pre-deploy backup:
+   ```powershell
+   cd "D:\SteamLibrary\steamapps\common\Star Wars Empire at War\corruption"
+   Copy-Item powrprof.dll.backup-* powrprof.dll -Force
+   ```
+3. Open an issue with:
+   - Which feature was toggled when the crash happened
+   - The SHA256 of the DLL that was running
+   - The last few lines of `swfoc_bridge.log` in the game directory (if any)
+   - The game version (Steam build number)
+
+**Preventive:** Before installing a new `SetHP` detour, the bridge
+verifies the 6-byte prologue `40 53 48 83 EC 60` (push rbx; sub rsp,
+60h) still matches. If SWFOC shipped a patch that moved SetHP's address
+or changed the prologue, the hook install refuses and logs a warning.
+Check `swfoc_bridge.log` for this message BEFORE enabling any combat
+feature after a game update.

+
+## 1. Tab inventory
+
+The current `MainWindow.xaml` declares **16** `TabItem` elements inside the main `TabControl` (`Grid.Row="1"`). Line numbers are from `src/SwfocTrainer.App/MainWindow.xaml` at the time of this audit (file length: 882 lines).
+
+| # | Tab Name | Purpose | Backend Pipeline | Status |
+|---|----------|---------|-----------------|--------|
+| 1 | Runtime | Action execution + quick-action toggles (Credits, Fog, AI, God Mode, One Hit Kill, Unit Cap, Instant Build, Freeze Timer) | `SdkOperationRouter` + `ActionSymbolRegistry` + `SymbolTacticalGodMode` | LEGACY-BROKEN |
+| 2 | Live Ops | Selected-unit transaction lab (HP/shield/speed/damage/cooldown/vet/owner draft); spawn preset execution; action reliability refresh | `SelectedUnitTransactionService` / `SpawnPresetService` / `ActionReliabilityService` (internal, non-bridge) | STALE — services are memory-editor vintage; many depend on symbols that no longer resolve |
+| 3 | Save Editor | Load / parse / patch / validate save files; apply savepatch packs | `SaveCodec` / `SavePatchApplyService` (file-based, NOT bridge) | USEFUL (orthogonal to bridge) |
+| 4 | Profiles & Updates | Profile list + GitHub profile update poll | `IProfileRepository` / `IProfileUpdateService` | USEFUL (orthogonal to bridge) |
+| 5 | Unit Roster | Load + browse v5 roster entries | `IRosterBrowserService` (data-only, reads profile JSON) | STALE — pure read-only view, no bridge calls |
+| 6 | Spawner | Enhanced v5 spawn batch execution | `IEnhancedSpawnService` → internally `ILuaBridgeExecutor` | DEAD — service exists and ought to work but UI is wrapped around the legacy router for side effects |
+| 7 | Faction Dashboard | Capture per-faction snapshot cards | `IFactionDashboardService` | STALE — returns a stub snapshot, no live bridge call |
+| 8 | Planet Manager | Load planets + set planet owner | `IPlanetManagerService` → `SdkOperationRouter` (`set_planet_owner` action) | LEGACY-BROKEN |
+| 9 | Fleet Manager | Load fleet composition | `IFleetManagerService` (data-only read) | STALE |
+| 10 | Ownership | Transfer unit/planet ownership | `IOwnershipTransferService` → `SdkOperationRouter` | LEGACY-BROKEN |
+| 11 | AI Control | Suspend/resume/difficulty for AI | `IAiControlService` → `ILuaBridgeExecutor` (partial) | DEAD — service exists but UI pipes through legacy router on failure path |
+| 12 | Camera Director | Record/play camera paths | `ICameraDirectorService` → `ILuaBridgeExecutor` | DEAD |
+| 13 | Story Events | Fire story events | `IStoryEventService` → `ILuaBridgeExecutor` (`FireEventAsync`) | DEAD |
+| 14 | Damage Log | Poll + summarize combat damage | `IDamageLogService` (internal poll-only) | STALE |
+| 15 | Diplomacy | Set faction×faction relation | `IDiplomacyService` → `ILuaBridgeExecutor` | DEAD |
+| 16 | Corruption | Apply corruption on planet | `ICorruptionService` → `ILuaBridgeExecutor` | DEAD |
+
+### Status legend
+
+- **USEFUL** — Provides real value; uses a backend that still works.
+- **STALE** — Service compiles, UI renders, but the backend is a stub / data-only reader / hasn't been exercised against the current game binary.
+- **DEAD** — Tab exists, backend service genuinely routes through `ILuaBridgeExecutor`, but the UI hands control off through a helper-hook path that the current bridge build does not recognize, so nothing happens in-game. **This is the real opportunity.**
+- **LEGACY-BROKEN** — UI is wired to `SdkOperationRouter` / `ActionSymbolRegistry` / `SymbolTacticalGodMode` which fail at symbol resolution on the current build.
+
+---
+
+## 2. Button inventory (sampled)
+
+For each tab, the 2–3 most prominent buttons and where they ultimately route.
+
+### Tab 1 — Runtime
+
+| Button | Command binding | Invokes | Backend path |
+|---|---|---|---|
+| God Mode | `QuickGodModeCommand` | `QuickGodModeAsync()` in `MainViewModelQuickActionsBase.cs` (line 221) | Builds payload `{ symbol: SymbolTacticalGodMode, boolValue: !active }` and routes through `QuickRunActionAsync(ActionToggleTacticalGodMode, …)` → `SdkOperationRouter` — **LEGACY-BROKEN** |
+| One Hit Kill | `QuickOneHitCommand` | `QuickOneHitAsync()` (line 230) | Same as God Mode but `SymbolTacticalOneHitMode` / `ActionToggleTacticalOneHitMode` — **LEGACY-BROKEN** |
+| Set Credits | `QuickSetCreditsCommand` | `QuickSetCreditsAsync()` | `QuickRunActionAsync(ActionSetCredits, …)` → `SdkOperationRouter` — **LEGACY-BROKEN** |

+
+| Button | Command binding | Invokes | Backend path |
+|---|---|---|---|
+| Capture Snapshots | `CaptureFactionSnapshotsCommand` | `CaptureFactionSnapshotsAsync()` | `IFactionDashboardService.CaptureSnapshotsAsync` — returns a static stub snapshot — **STALE** |

+
+---
+
+## 3. Service reach (dark services)
+
+Grep of `src/SwfocTrainer.Core/Services/*.cs` cross-referenced against `src/SwfocTrainer.App/**/*.xaml` for their interface names.
+
+| Service (interface) | ViewModel refs (C# files) | XAML refs (actual UI bindings) | Verdict |
+|---|---|---|---|
+| `IGodModeService` | 5 | **0** | DARK (bridge call exists, no button) |
+| `IOneHitKillService` | 5 | **0** | DARK |
+| `IEconomyService` | 23 | **0** | DARK |
+| `IHeroRespawnService` | 8 | **0** | DARK |
+| `IUnitInspectorService` | 6 | **0** | DARK |
+| `IHardpointService` | 5 | **0** | DARK |
+| `ICrashAnalyzerService` | 5 | **0** | DARK |
+| `IMaphackService` | 8 | **0** | DARK |
+| `IFactionSwitchService` | 22 | **0** | DARK (registered in DI, unused in UI) |
+| `ICorruptionService` | 28 | **0** | DARK |
+| `IDiplomacyService` | 28 | **0** | DARK |
+| `IStoryEventService` | 28 | **0** | DARK |
+| `IAiControlService` | 22 | **0** | DARK |
+| `ICooldownManagerService` | 22 | **0** | DARK |
+| `ICameraDirectorService` | 22 | **0** | DARK |
+| `IOwnershipTransferService` | 22 | **0** | DARK |
+| `IPlanetManagerService` | 28 | **0** | DARK |
+| `IFleetManagerService` | 22 | **0** | DARK |
+| `IDamageLogService` | 28 | **0** | DARK |
+| `IModConflictDetectorService` | 22 | **0** | DARK |
+| `IRosterBrowserService` | 22 | **0** | DARK |
+| `IFactionDashboardService` | 22 | **0** | DARK |
+| `IEnhancedSpawnService` | 22 | **0** | DARK |
+
+**23 out of 23 sampled services have zero direct XAML bindings.** ViewModel "references" are exclusively via the `MainViewModelDependencies` struct and factory injection (see `MainViewModelDependencies.cs`). The commands eventually constructed from these services do exist, but their button-side bindings route through the `ActionId`-based `QuickRunActionAsync` / `ExecuteActionCommand` pattern that resolves against the symbol registry. The symbol registry failing is why nothing reaches the bridge.
+
+### The "8 missing from DI" problem
+
+The 8 bridge-direct services below are NOT even registered in `src/SwfocTrainer.App/Program.cs`. They are present in source, instantiable, and have contracts (`IBridgeHelperServices.cs`), but `Program.cs::RegisterCoreServices` does not include them:
+
+- `IGodModeService`
+- `IOneHitKillService`
+- `IEconomyService`
+- `IHeroRespawnService`
+- `IUnitInspectorService`
+- `IHardpointService`
+- `ICrashAnalyzerService`
+- `IMaphackService`
+
+**V2 must register these itself** (Program.cs addition or manual instantiation in `MainWindowV2.xaml.cs`). Agent A and Agent B are not expected to touch this.
+
+---
+
+## 4. Legacy pipeline reach
+
+Grep results for `SdkOperationRouter` / `ActionSymbolRegistry` / `SymbolTacticalGodMode` across the editor source tree (non-test files).
+
+### In `src/SwfocTrainer.App/`:
+
+- `src/SwfocTrainer.App/Program.cs:119` — DI registration `services.AddSingleton<ISdkOperationRouter, SdkOperationRouter>();` (still needed for the legacy UI fallback)
+- `src/SwfocTrainer.App/ViewModels/MainViewModelDefaults.cs:25` — `internal const string SymbolTacticalGodMode = "tactical_god_mode";`
+- `src/SwfocTrainer.App/ViewModels/MainViewModelDefaults.cs:65` — `[ActionToggleTacticalGodMode] = SymbolTacticalGodMode,` (action→symbol lookup table)
+- `src/SwfocTrainer.App/ViewModels/MainViewModelCoreStateBase.cs:46` — `protected const string SymbolTacticalGodMode = MainViewModelDefaults.SymbolTacticalGodMode;` (re-export)
+- `src/SwfocTrainer.App/ViewModels/MainViewModelQuickActionsBase.cs:225-228` — Quick-action `QuickGodModeAsync()` builds payload with `SymbolTacticalGodMode` and routes through `QuickRunActionAsync` → `SdkOperationRouter`
+
+### In `src/SwfocTrainer.Core/`:
+
+- `src/SwfocTrainer.Core/Services/SdkOperationRouter.cs` — implementation
+- `src/SwfocTrainer.Core/Services/ActionSymbolRegistry.cs` — implementation
+- `src/SwfocTrainer.Core/Contracts/ISdkOperationRouter.cs` — contract
+- `src/SwfocTrainer.Core/Services/ActionReliabilityService.cs` — consumes `ISdkOperationRouter` for reliability probes
+
+### In `src/SwfocTrainer.Runtime/`:
+
+- `src/SwfocTrainer.Runtime/Services/RuntimeAdapter.cs` — consumes `ISdkOperationRouter`
+- `src/SwfocTrainer.Runtime/Services/RuntimeAdapter.State.cs` — same
+- `src/SwfocTrainer.Runtime/Services/ModMechanicDetectionService.cs` — same
+
+### In test projects:
+
+- `tests/SwfocTrainer.Tests/Core/SdkOperationRouterTests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave6Tests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave11CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave8bCoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave8CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Runtime/RuntimeAdapterAsyncWave7Tests.cs`
+- `tests/SwfocTrainer.Tests/Runtime/RuntimeAdapterWave6Tests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave2CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/App/MainViewModelDefaultsWave5Tests.cs`
+
+**Total reach: 20 files.** The 5 most-important legacy touches are in `src/SwfocTrainer.App/ViewModels/MainViewModel{Defaults,CoreStateBase,QuickActionsBase}.cs`, `src/SwfocTrainer.App/Program.cs`, and the legacy `MainWindow.xaml` command bindings. V2 must touch zero of these.
+
+---
+
+## 5. Summary verdict
+
+**Full rebuild is justified.** The audit evidence:
+
+1. **Zero XAML bindings point at bridge services.** Every one of the 23 bridge-aware services exists in source and is referenced only through the `MainViewModelDependencies` injection record. The actual button bindings (`QuickGodModeCommand`, `ExecuteActionCommand`, etc.) route through `QuickRunActionAsync` / `ExecuteActionAsync`, which both hit `SdkOperationRouter` first and fall back to helper-hook paths that are not wired to the current bridge build.
+2. **The 8 newest bridge services (GodMode, OneHitKill, Economy, HeroRespawn, UnitInspector, Hardpoint, CrashAnalyzer, Maphack) are not even in Program.cs DI.** A surgical rewire cannot succeed without editing `Program.cs::RegisterCoreServices`, `MainViewModelDependencies`, the factory context record, and the 21 `MainViewModel*.cs` partial-class files. That blast radius is strictly larger than writing a new window from scratch.
+3. **The symbol registry is the chokepoint.** `SymbolTacticalGodMode` / `ActionToggleTacticalGodMode` / `ActionSymbolRegistry` exist to map stable button IDs to the hand-maintained symbol table that was the pre-bridge approach. Every broken button in the user's live test came back with the `"symbol":"invalid"` error from `SdkOperationRouter`. This pipeline will not become correct by adding buttons — it needs to be bypassed.
+4. **The correct pipeline already exists.** `LuaBridgeExecutor` + `NamedPipeLuaBridgeClient` are production-quality, unit-tested, and directly call `\\.\pipe\swfoc_bridge`. The per-feature services (`GodModeService.cs`, `OneHitKillService.cs`, etc.) already wrap them correctly. What's missing is the six-tab window that actually uses them.
+5. **The previous session's B3 refusal was correct.** A surgical fix inside the legacy MainViewModel would have touched 30+ files and required re-plumbing the symbol registry. Building `MainWindowV2` alongside, with a launch switch for fallback, preserves the legacy UI while delivering a working alternative.
+
+**Recommendation:** ship the V2 rebuild, validate against the live bridge in the next session, then execute the quarantine plan below once a human has clicked at least one V2 button successfully in-game.
+
+---
+
+## Quarantine plan for legacy pipeline
+
+The following files should be moved to `legacy_to_delete/` **after V2 is validated live** (not this session). Do not move these files yet.
+
+### Core legacy services (delete after V2 validated)
+
+1. `src/SwfocTrainer.Core/Services/SdkOperationRouter.cs`
+2. `src/SwfocTrainer.Core/Services/ActionSymbolRegistry.cs`
+3. `src/SwfocTrainer.Core/Contracts/ISdkOperationRouter.cs`
+
+### Legacy view-model spaghetti (21 partial files)
+
+The `MainViewModel` partial class lives across 21 files. All of them must be deleted together — they form a single `partial class MainViewModel` and cannot be removed piecemeal without compile errors.
+
+4. `src/SwfocTrainer.App/ViewModels/MainViewModel.cs`
+5. `src/SwfocTrainer.App/ViewModels/MainViewModelAttachHelpers.cs`
+6. `src/SwfocTrainer.App/ViewModels/MainViewModelBindableMembersBase.cs`
+7. `src/SwfocTrainer.App/ViewModels/MainViewModelCoreStateBase.cs`
+8. `src/SwfocTrainer.App/ViewModels/MainViewModelCreditsHelpers.cs`
+9. `src/SwfocTrainer.App/ViewModels/MainViewModelDefaults.cs`
+10. `src/SwfocTrainer.App/ViewModels/MainViewModelDependencies.cs`
+11. `src/SwfocTrainer.App/ViewModels/MainViewModelDiagnostics.cs`
+12. `src/SwfocTrainer.App/ViewModels/MainViewModelDraftBuildResult.cs`
+13. `src/SwfocTrainer.App/ViewModels/MainViewModelFactories.cs`
+14. `src/SwfocTrainer.App/ViewModels/MainViewModelHotkeyHelpers.cs`
+15. `src/SwfocTrainer.App/ViewModels/MainViewModelLiveOpsBase.cs`
+16. `src/SwfocTrainer.App/ViewModels/MainViewModelPayloadHelpers.cs`
+17. `src/SwfocTrainer.App/ViewModels/MainViewModelQuickActionHelpers.cs`
+18. `src/SwfocTrainer.App/ViewModels/MainViewModelQuickActionsBase.cs`
+19. `src/SwfocTrainer.App/ViewModels/MainViewModelRuntimeModeOverrideHelpers.cs`
+20. `src/SwfocTrainer.App/ViewModels/MainViewModelSaveOpsBase.cs`
+21. `src/SwfocTrainer.App/ViewModels/MainViewModelSelectedUnitDraftHelpers.cs`
+22. `src/SwfocTrainer.App/ViewModels/MainViewModelSelectedUnitParsingHelpers.cs`
+23. `src/SwfocTrainer.App/ViewModels/MainViewModelSpawnHelpers.cs`
+24. `src/SwfocTrainer.App/ViewModels/MainViewModelV5FeaturesBase.cs`
+
+### Legacy WPF window
+
+25. `src/SwfocTrainer.App/MainWindow.xaml`
+26. `src/SwfocTrainer.App/MainWindow.xaml.cs`
+
+### Legacy-pipeline-only tests
+
+These tests exclusively cover `SdkOperationRouter` / `ActionSymbolRegistry` / `SymbolTacticalGodMode`. Other tests that merely mention those symbols while testing something else should NOT be deleted — verify by grep before moving.
+
+27. `tests/SwfocTrainer.Tests/Core/SdkOperationRouterTests.cs` — named after the target, exclusively legacy
+
+**Tests that are NOT candidates for deletion** (they exercise adjacent systems and only reference the legacy symbols through transitive dependencies):
+
+- `tests/SwfocTrainer.Tests/Core/CoreWave6Tests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave11CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave8bCoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave8CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/Runtime/RuntimeAdapterAsyncWave7Tests.cs`
+- `tests/SwfocTrainer.Tests/Runtime/RuntimeAdapterWave6Tests.cs`
+- `tests/SwfocTrainer.Tests/Core/CoreWave2CoverageTests.cs`
+- `tests/SwfocTrainer.Tests/App/MainViewModelDefaultsWave5Tests.cs`
+
+These will lose coverage when the legacy code is deleted. Re-verify their still-relevant assertions against V2 code during quarantine execution.
+
+### Quarantine execution order (future session)
+
+1. Confirm V2 has been used live against the bridge (human click-test).
+2. Delete legacy tests marked "exclusively legacy" above.
+3. Delete the 21 `MainViewModel*.cs` partial files together, then `MainWindow.xaml` + `MainWindow.xaml.cs`.
+4. Delete `SdkOperationRouter.cs`, `ActionSymbolRegistry.cs`, `ISdkOperationRouter.cs`.
+5. Run `dotnet build --no-incremental --verbosity normal` and fix transitive breakages in `RuntimeAdapter.cs`, `ActionReliabilityService.cs`, `ModMechanicDetectionService.cs`.
+6. Simplify `Program.cs::RegisterCoreServices` — drop the DI registration and the `MainViewModelDependencies` wiring.
+7. Remove the `--legacy-ui` flag from V2's `Main()` and make V2 the only window.
+8. Re-run tests. Expect ~10 deletions in `SdkOperationRouterTests.cs` and friends.

+# Iter 100-113 LIVE wires — operator quick reference
+
+**One-line example invocations for every LIVE flip from the 2026-04-28 master ralph loop session.**
+
+Copy-paste any of these into:
+- The editor's **Lua Playground tab**, or
+- The bridge's `\\.\pipe\swfoc_bridge` named pipe directly via `echo` / Cheat Engine, or
+- `SWFOC_DoString("...")` from inside an existing Lua script
+
+All wires return either `OK: <method> dispatched (LIVE — engine Lua API)` on success or `ERR: <reason>` on failure.
+
+---
+
+## Speed control (iter 100)
+
+```lua
+-- Set per-unit speed (absolute override, in engine units)
+return SWFOC_SetUnitSpeed(0xABCD, 250)
+
+-- Read the current per-unit speed (returns -1 if no override active)
+return SWFOC_GetUnitSpeed(0xABCD)
+
+-- Set ALL units owned by slot 0 to absolute speed 350
+return SWFOC_SetPerFactionSpeedMultiplier(0, 350)
+
+-- Revert per-unit speed back to engine's natural max
+return SWFOC_ClearUnitSpeedOverride(0xABCD)
+```
+
+`0xABCD` = the 64-bit obj_addr from the Tactical Units tab. Replace with your real address.
+
+---
+
+## Damage scaling (iter 96, editor backfilled iter 102)
+
+```lua
+-- Scale every incoming damage by 2.0× globally (Take_Damage_Outer detour)
+return SWFOC_SetDamageMultiplierGlobal(2.0)
+
+-- Read the current global multiplier
+return SWFOC_GetDamageMultiplierGlobal()
+
+-- Reset to normal damage
+return SWFOC_SetDamageMultiplierGlobal(1.0)
+```
+
+---
+
+## Camera (iter 107)
+
+```lua
+-- Galactic mode: scroll to a planet by name
+return SWFOC_ScrollCameraToTarget('Find_Planet("Yavin")')
+
+-- Tactical mode: scroll to a specific unit
+return SWFOC_ScrollCameraToTarget('Find_First_Object("Empire_AT_AT")')
+
+-- Scroll to the third Rebel Trooper Squad in the world
+return SWFOC_ScrollCameraToTarget('Find_Object_Type("Rebel_Trooper_Squad")[2]')
+```
+
+Note: the outer call uses single quotes so the inner `Find_*` can use double quotes for its string argument (no escape needed). Lua accepts either quote style for string literals.
+
+---
+
+## Galactic — change unit ownership (iter 108)
+
+```lua
+-- Convert the first Empire AT-AT to the Rebel faction
+return SWFOC_ChangeUnitOwner('Find_First_Object("Empire_AT_AT")', 'Find_Player("REBEL")')
+
+-- Convert all Empire stormtroopers to Underworld (one at a time — repeat for each)
+return SWFOC_ChangeUnitOwner('Find_First_Object("Empire_Stormtrooper_Squad")', 'Find_Player("UNDERWORLD")')
+```
+
+The engine's `Change_Owner` updates ownership, fires UI events, plays audio, processes corruption, AND updates AI budgets. Full "swap sides" engine behaviour.

+## Spawning (iter 109)
+
+```lua
+-- Spawn a Rebel trooper squad at the origin
+return SWFOC_SpawnUnitLua(
+    'Find_Player("REBEL")',
+    'Find_Object_Type("Rebel_Trooper_Squad")',
+    'Create_Position(0, 0, 0)')
+
+-- Spawn an Empire AT-AT at coords (100, 200, 0)

+    'Find_Player("EMPIRE")',
+    'Find_Object_Type("Empire_AT_AT")',
+    'Create_Position(100, 200, 0)')
+```
+
+---
+
+## Per-unit toggles (iter 110, 111)
+
+```lua
+-- Make a unit invulnerable (propagates via BehaviorAttach to all hardpoints)
+return SWFOC_MakeUnitInvulnLua('Find_First_Object("Empire_AT_AT")', 'true')
+
+-- Revert
+return SWFOC_MakeUnitInvulnLua('Find_First_Object("Empire_AT_AT")', 'false')
+
+-- Hide a unit (visibility toggle, doesn't remove from world)
+return SWFOC_HideUnitLua('Find_First_Object("Empire_AT_AT")', 'true')
+
+-- Lock the AI away from controlling a unit
+return SWFOC_PreventAiUsageLua('Find_First_Object("Empire_AT_AT")', 'true')
+
+-- Make a unit non-selectable (operator can still see it but can't click it)
+return SWFOC_SetUnitSelectableLua('Find_First_Object("Empire_AT_AT")', 'false')
+```
+
+---
+
+## Per-unit actions (iter 112)
+
+```lua
+-- Despawn (cleanly remove)
+return SWFOC_DespawnUnitLua('Find_First_Object("Empire_AT_AT")')
+
+-- Stop current action (interrupt move/attack)
+return SWFOC_StopUnitLua('Find_First_Object("Empire_AT_AT")')
+
+-- Retreat (engine flees the unit toward safety)
+return SWFOC_RetreatUnitLua('Find_First_Object("Rebel_Trooper_Squad")')
+```
+
+---
+
+## Universal escape hatch (iter 113)
+
+For any engine Lua method NOT explicitly catalogued — calls
+`(<obj>):<method>(<args>)` via DoString.
+
+```lua
+-- Give a player money
+return SWFOC_CallObjMethodLua('Find_Player("REBEL")', 'Give_Money', '5000')
+
+-- Heal a unit (engine method — no args)
+return SWFOC_CallObjMethodLua('Find_First_Object("Empire_AT_AT")', 'Heal', '')
+
+-- Enable a behavior on a unit (multi-arg)
+return SWFOC_CallObjMethodLua(
+    'Find_First_Object("Empire_AT_AT")',
+    'Enable_Behavior',
+    '"INVULNERABLE", true')
+
+-- Set a player's tech level

+
+-- Activate a faction superweapon
+return SWFOC_CallObjMethodLua('Find_Player("EMPIRE")', 'Activate_Power', '"DEATH_STAR"')
+```
+
+---
+
+## Live-test priority
+
+If you can only test 5 things to validate the session, do these in order:
+
+1. **`SWFOC_SetUnitSpeed`** — easiest to verify: pick any unit, set speed 250, watch it walk much faster.
+2. **`SWFOC_SetDamageMultiplierGlobal(2.0)`** — take a swing at any unit, watch HP drop double.
+3. **`SWFOC_ScrollCameraToTarget('Find_Planet("Yavin")')`** — galactic-mode camera pan.
+4. **`SWFOC_ChangeUnitOwner(...)`** — convert an enemy unit, watch UI events fire.
+5. **`SWFOC_CallObjMethodLua('Find_Player("REBEL")', 'Give_Money', '5000')`** — credits jump 5000, validates the universal escape hatch.
+
+If any fail, capture the bridge log line — the bridge already records `ERR: <method> raised engine error rc=<n>` on failure with the full DoString source that was dispatched.
+
+---
+
+## Deferred — XML-attribute-only family (still PHASE 2 PENDING)
+
+These engine fields are baked from XML at unit construction; no runtime setter exists. They need either RTTI dissection of the per-unit struct OR a MinHook on the relevant tick/update path. Documented for future arc — don't try to call them yet.
+
+- `SWFOC_SetFireRate` (iter 101 finding)
+- `SWFOC_SetHeroRespawnTimer` (iter 104)
+- `SWFOC_SetPermadeath` (iter 104)
+- `SWFOC_SetUnitShield` (iter 105)
+- `SWFOC_SetGameSpeed` (no engine helper pinned)
+- `SWFOC_FreeCam` (no engine `Free_Cam` Lua API)
+- `SWFOC_SetCameraPos` (engine API takes Lua position-userdata, not raw floats)
+
+---
+
+## Native UX surfaces in the editor (iter 117-119, 2026-04-29)
+
+You no longer have to paste these wires into the Lua Playground — every iter 100-113 wire now has a native button somewhere in the editor. The Playground preset menu (iter 116) is still there as a power-user shortcut, but the per-tab buttons are the recommended path for routine operator workflows.
+
+### Unit Control tab — "Selected Unit Lua Actions (iter 117-118 LIVE)" GroupBox
+
+Paste a unit-handle expression (e.g. `Find_First_Object("Empire_AT_AT")`) into the first TextBox once. Then click any of these buttons:
+
+- **Make invuln ON / OFF** → iter 110 (`SWFOC_MakeUnitInvulnLua`)
+- **Hide ON / OFF** → iter 111 (`SWFOC_HideUnitLua`)
+- **Lock from AI / Unlock to AI** → iter 111 (`SWFOC_PreventAiUsageLua`)
+- **Selectable ON / OFF** → iter 111 (`SWFOC_SetUnitSelectableLua`)
+- **Despawn / Stop / Retreat** → iter 112 (`SWFOC_DespawnUnitLua` / `StopUnitLua` / `RetreatUnitLua`)
+- **Change unit owner →** (separate row, takes a 2nd TextBox for `Find_Player(...)`) → iter 108 (`SWFOC_ChangeUnitOwner`)
+
+### Spawning tab — "Spawn unit via Lua (iter 119 LIVE)" GroupBox
+
+Three TextBoxes for player / type / position Lua expressions, plus a button. This is the **LIVE alternative** to the existing PHASE 2 PENDING `SWFOC_SpawnUnit` Phase-1-mirror Spawn button — operators can finally spawn units that genuinely appear in the running game.
+
+- **Player Lua**: `Find_Player("REBEL")`
+- **Type Lua**: `Find_Object_Type("Rebel_Trooper_Squad")`
+- **Position Lua**: `Create_Position(0, 0, 0)`
+- Click **Spawn (Lua, LIVE) →** → iter 109 (`SWFOC_SpawnUnitLua`)
+
+### Wires that already had earlier UX surfaces
+
+- **Speed (iter 100)** — Speed tab "Apply (per-unit)" / per-faction / Revert buttons (iter 100/102)
+- **Damage (iter 96/97/102)** — Combat tab "Apply (GLOBAL)" / "Apply (per-slot)" buttons (iter 102)
+- **Camera (iter 107)** — Camera & Debug tab "Scroll camera to target" GroupBox (iter 107)
+- **Universal escape hatch (iter 113, `SWFOC_CallObjMethodLua`)** — intentionally kept Lua-Playground-only. Too generic to deserve a dedicated button surface; lives in the iter 116 preset menu and is the documented "everything else" tool.
+
+### Wire-format pin tests
+
+Each iter 117/118/119 dispatcher method has a wire-format regression test that pins the exact `SWFOC_X('expr1', 'expr2'...)` shape:
+
+- `tests/SwfocTrainer.Tests/Regression/Iter117UnitLuaCallShapeTests.cs` (10 cases)
+- `tests/SwfocTrainer.Tests/Regression/Iter118ChangeUnitOwnerShapeTests.cs` (5 cases)
+- `tests/SwfocTrainer.Tests/Regression/Iter119SpawnUnitLuaShapeTests.cs` (4 cases)
+
+If a future bridge-side rename or quote-style change drifts the wire format, these fire at the dispatcher boundary instead of waiting for a runtime mismatch in the live game.

+## All 134 Binary-Confirmed + 271 Community-Documented Functions
+
+---
+
+## How to Call These Functions via the DLL Bridge
+
+With `lua_load` + `lua_pcall` + `lua_gettable`, you can now execute **any Lua code** the game supports. Two methods:
+
+### Method 1: Named Pipe (External — from CE, .NET trainer, Python, etc.)
+```
+echo 'SWFOC_SetCredits(50000)' | ncat --send-only \\.\pipe\swfoc_bridge
+```
+
+### Method 2: SWFOC_DoString (From Lua scripts inside the game)
+```lua
+SWFOC_DoString("Spawn_Unit(player, Find_Object_Type('AT_AT'), Create_Position(0,0,0))")
+```
+
+### Method 3: Direct DLL Function (From registered SWFOC_* functions)
+```lua
+local slot, faction = SWFOC_GetLocalPlayer()
+SWFOC_SetCredits(999999)
+```
+
+---
+

+## 7. Example Pipe Commands
+
+Once the pipe listener is running, send these from any external tool:
+
+```bash
+# Give 50000 credits
+echo 'SWFOC_SetCredits(50000)' > \\.\pipe\swfoc_bridge
+
+# Spawn an AT-AT at origin
+echo 'Spawn_Unit(SWFOC_GetLocalPlayer(), Find_Object_Type("AT_AT"), Create_Position(0,0,0))' > \\.\pipe\swfoc_bridge
+
+# Make all your units invincible
+echo 'for _,u in pairs(Find_All_Objects_Of_Type(nil)) do if u:Get_Owner() == SWFOC_GetLocalPlayer() then u:Make_Invulnerable(true) end end' > \\.\pipe\swfoc_bridge
+
+# Max tech
+echo 'SWFOC_SetTechLevel(5)' > \\.\pipe\swfoc_bridge

+| `0x348` | `uint8` | hardpoint_manager_index | high | Shorthand for component_lookup_table[0x16]. When 0xFF, the object uses the direct HP path (no hardpoint indirection). When any other value, damage routing goes through the hardpoint manager. Checked in Make_Invulnerable and Take_Damage paths. |
+| `0x34B` | `uint8` | ability_manager_index | medium | Shorthand for component_lookup_table[0x19]. When != -1, the object has an ability system. Checked in FUN_1403A4820 to look up ability component and check +0x54 state. |
+| `0x36F` | `uint8` | transform_component_index | medium | Shorthand for component_lookup_table[0x3D]. When != -1, the object has a transform component. Checked in Change_Owner for position updates. |
+| `0x39E` | `uint8` | registered_with_session_flag | high | Set to 1 when FUN_14029BFE0(session_context, this) is called, indicating the object has been registered with the game session manager. Checked before calling FUN_14029BFE0 to avoid double-registration. Set in FUN_14038CB30, FUN_1403989A0, FUN_1403A4820. |
+| `0x39F` | `uint8` | spawn_complete_flag | high | Set to 1 in FUN_1403989A0 during the spawn initialization sequence. When == 1 in FUN_1403A4820, enables visual model attachment and hero clash node setup. When == 0 in FUN_1403A4820, skips animation setup. |
+| `0x3A0` | `uint8` | state_flags_bitfield | high | Bitfield of state/dirty flags. Bit 0 (0x01): HP change notification dirty flag (set by SetHP when object_id matches tracked ID). Bit 1 (0x02): used in ScheduleHeroRespawn -- if set, hero respawn is blocked. Bit 3 (0x08): animation/combat state flag (cleared/set in FUN_1403A92F0). Bit 4 (0x10): position lock flag (blocks render position updates in FUN_1403A8710). Bit 6 (0x40): used in ScheduleHeroRespawn -- if set alongside 0x02, respawn is blocked. Bit 7 (0x80): sign bit -- checked in FUN_1403989A0 (if < 0, skips hardpoint allocation). |
+| `0x3A1` | `uint8` | dirty_flags_bitfield | high | Dirty/state flags bitfield. Bit 0 (0x01): transform dirty -- set in FUN_1403A8710 when position changes, cleared in FUN_1403AC530 at the end of transform update. Bit 3 (0x08): checked in FUN_1403A4820 for animation state. Bit 7 (0x80): prevent-death flag. When set, Take_Damage_Impl clamps HP to max(1.0, current_hp). |
+| `0x3A6` | `uint16` | state_0x3A6 | low | Cleared to 0 in FUN_1403989A0 during spawn init. |
+| `0x3A7` | `uint8` | invulnerability_flag | high | Invulnerability state. Checked by Take_Damage_Outer at multiple points. WARNING: Setting this byte manually does NOT work -- you must call Make_Invulnerable_Setter (RVA 0x3ABB80) which propagates to hardpoints and updates the behavior system. Located within the 0x3A6 cleared region. |
+| `0x3A8` | `uint32` | state_0x3A8 | low | Cleared to 0 in FUN_1403989A0 during spawn init. |
+| `0x3B5` | `uint32` | state_0x3B5 | low | Cleared to 0 in FUN_1403989A0. |
+| `0x3B9` | `uint8` | state_0x3B9 | low | Cleared to 0 in FUN_1403989A0. |
+| `0x3C0` | `uint64` | state_0x3C0 | medium | Cleared to 0 in FUN_1403989A0. Likely the last field -- places minimum struct size at 0x3C8. |

+## RE Findings Detail
+
+**Analysis**: SWFOC AI System Decompilation — Agent 3D Output
+
+Comprehensive map of the Alamo engine AI decision loop, subsystems, enable/disable mechanisms, production queue, diplomacy, and difficulty systems. Derived from Ghidra static analysis of StarWarsG.exe (x86_64).
+
+- **Date**: 2026-04-04
+
+
+### Architecture Overview
+
+- **summary**: The AI system is a hierarchical, goal-driven architecture centered on the TheAIClass singleton. Each non-human player gets an AIPlayerClass instance containing 7 ServicedAISystem subsystems. The system uses a perception-planning-execution loop with per-mode specializations (Galactic, Space, Land). Production is handled by a FiniteStateMachine-based AIBuildTaskClass with 25 named states. Diplomacy is event-driven (AllyEventClass) rather than polled. Difficulty is managed by DifficultyAdjustmentManagerClass (a database manager of DifficultyAdjustmentClass records).
+- **key_design_patterns**: Singleton pattern (TheAIClass, TheAIDataManagerClass, TheAIPlayerTypeManagerClass, TheAIGoalTypeManagerClass, TheAITemplateManagerClass), ServicedAISystemClass — base class for all tickable AI subsystems (inherits AIDiagnosticsClass, stores owner reference at +0x0), FiniteStateMachineClass<enum_BuildTaskStates> — state machine driving AIBuildTaskClass production, PerceptualEvaluatorClass hierarchy — 20+ evaluator types for sensing game state, Signal/Listener pattern — AILearningSystemClass uses SignalListenerClass + SignalGeneratorClass, Lua binding wrappers — LuaMemberFunctionWrapper<T> for exposing AI internals to Lua scripts, DatabaseObjectManagerClass<T> — manages typed collections (goals, templates, difficulty adjustments)
+

+
+- **description**: AI enable/disable operates at multiple levels: (1) TheAIClass singleton state_flags (0x01010101 = all active), (2) Per-player Is_Human flag on PlayerObject, (3) Per-unit Prevent_AI_Usage Lua method, (4) Suspend_AI global Lua function (time-based), (5) Player::Enable_As_Actor() Lua method. The AI system checks Is_Human on the player to decide whether to create an AIPlayerClass. The Suspend_AI function likely sets a timer on the TheAIClass singleton that suppresses all AI ticking.
+- **global_ai_singleton**:
+  - **rva**: TheAIClass singleton via SingletonInstance at 0x7EED80

+  - **description**: PlayerObject has Is_Human and IsHumanControlled methods. AI-controlled players have Is_Human returning false. Enable_As_Actor() on a PlayerWrapper activates AI for that player. The engine checks these flags when creating/destroying AIPlayerClass instances.
+- **per_unit_control**:
+  - **prevent_ai_usage_method**: Prevent_AI_Usage(bool) on GameObjectWrapper
+  - **warning**: Crashes in tactical if unit has no active AI (community-documented bug).

+- **temporal_suspension**:
+  - **suspend_ai_function**: Suspend_AI(seconds) — global Lua function
+  - **description**: Pauses all AI processing for a specified number of seconds. Used during cinematics. Likely sets a countdown timer on TheAIClass or on the game clock that suppresses ServicedAISystemClass::Service calls.
+
+
+### Diplomacy System
+
+- **description**: Diplomacy in the Alamo engine is NOT a continuous state machine — it is event-driven. Alliance/enemy changes are discrete events (AllyEventClass) sent through the ScheduledEventClass system. The PlayerObject stores diplomatic state accessed via Is_Enemy(player) and Is_Ally(player) Lua methods. Make_Ally/Make_Enemy are global Lua functions that fire AllyEventClass events. CRITICAL: diplomatic state resets on every game mode change (galactic<->tactical transition).

+### Access Patterns
+
+- **get_current_camera_position**:
+  - **description**: How to read the active camera's world position at runtime.
+  - **chain**: 1. Read GameModeManagerClass pointer at [module_base + 0xB153E0], 2. Call GetModeByType(mode_mgr, 0) to get the current galactic GameModeClass (or iterate to find active), 3. Read CameraClass pointer at [GameModeClass + 0x90], 4. Read camera_state_ptr at [CameraClass + 0x40], 5. Position X = float at [camera_state + 0x0C], 6. Position Y = float at [camera_state + 0x1C], 7. Position Z = float at [camera_state + 0x2C]
+  - **pointer_chain_notation**: [module+0xB153E0] -> GetModeByType(0) -> +0x90 -> +0x40 -> {+0x0C, +0x1C, +0x2C}
+  - **confidence**: CONFIRMED
+- **get_camera_zoom_level**:
+  - **description**: How to read the camera's zoom/FOV.
+  - **chain**: 1-4. Same as position chain above, 5. FOV = float at [camera_state + 0x48] (radians), 6. Aspect = float at [camera_state + 0x4C]
+  - **confidence**: CONFIRMED
+- **get_camera_rotation**:
+  - **description**: Camera orientation is encoded in the 3x4 matrix at camera_state +0x00. The forward direction is the Z column negated: forward = (-[+0x08], -[+0x18], 0). For the galactic camera, the rotation angle is stored in the GalacticCameraClass globals at 0xB1599C (pitch angle in radians).
+  - **confidence**: CONFIRMED
+- **free_camera_unlock_mechanism**:
+  - **description**: The GalacticCameraClass::Update (RVA 0x3C2C00) has an update_state field at +0x44. When update_state >= 4, the camera operates in free orbit mode with no position constraints. Setting update_state to a high value (e.g., 5) and writing custom look-at coordinates (+0x0C/+0x10/+0x14) and orbit distance (+0x34) would effectively unlock the camera. For a full free camera: bypass GalacticCameraClass::Update entirely by NOPing the call, then write the camera_state sub-object's orientation matrix directly.
+  - **nop_approach**: Find the call to GalacticCameraClass::Update and NOP it. Then write the camera_state transform matrix (12 floats at sub-object +0x00) directly each frame.
+  - **confidence**: DISCOVERED
+  - **status**: Theoretical — needs runtime validation
+- **get_selected_unit**:
+  - **description**: The selection system works through the event mechanism. SelectEventClass (type 5) and SelectAllEventClass (type 37) write to GameModeManagerClass+0xB4. The actual selected object list is maintained per-GameModeClass in the DynamicVector<GameObjectClass*> structures within the mode. The GameModeClass constructor at offset this[0x38] (0x1C0) initializes a DynamicVectorClass<DynamicVectorClass<GameObjectClass*>> which holds per-player selection groups.
+  - **chain**: 1. Read GameModeManagerClass pointer at [module_base + 0xB153E0], 2. Get active GameModeClass via GetModeByType, 3. The selection state is at GameModeClass — the DynamicVector<DynamicVectorClass<GameObjectClass*>> at approximately offset 0x1C0-0x1D8 holds per-player selection lists, 4. For the local player, index into the outer vector by player slot, 5. The inner DynamicVectorClass contains GameObjectClass* pointers to selected units
+  - **confidence**: DISCOVERED
+  - **notes**: Exact offset for the selection vector needs runtime verification. The GameModeClass constructor shows DynamicVectorClass<DynamicVectorClass<GameObjectClass*>> at this[0x3B] (offset 0x1D8) with initialization using DAT_140a16fb0 (which is the max player count).
+- **selection_via_selectbehavior**:
+  - **description**: Individual objects have a SelectBehaviorClass (size 0x58) attached as a behavior component. To check if a specific GameObjectClass is selected, query its SelectionDataPackClass data pack. The data pack is attached through the standard data-pack system.

+### Next Steps
+
+- RUNTIME VALIDATION: Attach CE with admin privileges or use the DLL bridge to resolve ASLR base and validate all offsets at runtime.
+- SELECTION VECTOR: Use runtime breakpoints on FUN_14028d930 to trace the exact selection list storage within GameModeClass. The DynamicVector<DynamicVectorClass<GameObjectClass*>> at GameModeClass+0x1D8 is the most likely candidate.
+- LAND/SPACE CAMERAS: LandModeClass and SpaceModeClass have their own camera controllers (not GalacticCameraClass). Decompile their update functions to map the tactical camera parameters.
+- FREE CAMERA: Implement free camera by: (a) finding the call to GalacticCameraClass::Update, (b) NOPing it, (c) writing the camera_state sub-object matrix directly via the DLL bridge.
+- SCREEN-TO-WORLD: The inverse view-projection matrix at camera_state+0x84 (or the engine param at RVA 0x1ADD70) provides the camera-to-world transform. Multiply a screen-space ray by this inverse to get world coordinates.

+### Death Sequence
+
+- **description**: When HP reaches 0.0 in Take_Damage_Impl, the death handler FUN_14039BDB0 is called. This is a complex function that handles: last-hit attribution, death animation selection, debris spawning, kill events, and object destruction.
+- **handler_function**:
+  - **rva**: 0x39BDB0
+  - **ghidra_va**: 0x14039BDB0
+- **sequence**: 1. Set death flag at obj+0x130 (OR with 0x40), 2. Record last-hit player (attacker's player ID stored at obj+0x110), 3. Signal death to behavior system (FUN_14038EB10), 4. If debug mode: call FUN_140392600 for death logging, 5. Notify AffectedByShield if present (obj+0x123 check, calls FUN_1405031A0), 6. Choose death animation: query GameObjectType for animation index (0x20 = special, iterate up to 2), 7. If death debris configured (type+0x23E8 or transport with units), spawn wreckage (FUN_1404D07E0), 8. Broadcast death event to the event system (event type 0x25), 9. Recursive: if object has child hardpoints (via obj+0x70 linked list), call death on children, 10. Determine spawn location for debris/explosion via QueryInterface(4), QI(5), or QI(0x16), 11. Push death record to global death queue (DAT_140B15418+0x42), 12. Destroy the object's visual representation (FUN_140265AE0), 13. Iterate sub-weapons: fire each weapon that is flagged as death-fire, 14. If hero unit: trigger hero respawn logic (ScheduleHeroRespawn at 0x48EB10), 15. Select death model/animation based on damage type (normal vs fire vs special), 16. Spawn death SFX and debris object at position, 17. If local player's unit: broadcast UI death notification
+
+
+### Shield System
+
+- **description**: Shields are separate from hull HP. Each unit can have a front shield (QueryInterface 0x0F -> BaseShieldBehaviorClass) and a rear shield (QueryInterface 0x10 -> ShieldBehaviorClass). Shield values are stored at obj+0xF0 sub-object.
+- **front_shield**:

+  - **max_value_source**: GameObjectType+0xDD4 (base) * difficulty_multiplier * ability_modifiers
+- **shield_depletion_triggers_hull_damage**:
+  - **description**: When SetRearShield (0x3A91E0) sets shield to 0 and FUN_14039B950 returns true, it calls Take_Damage_Outer (0x38A350) to begin hull damage. Same for SetFrontShield through BaseShieldBehavior. This means shields must be depleted before hull HP can be reduced through normal combat.
+  - **rear_shield_death_trigger**: FUN_140549810 at offset +0x88: calls FUN_14038A350 when shield <= 0 and FUN_14039B950 returns true
+- **shield_states**:
+  - **active**: shield_state = 1 (shields up, absorbing damage)
+  - **depleted**: shield_state = 2 (shields down, hull takes damage directly)
+  - **transition**: State change triggers visual/SFX events via FUN_140549CD0 and event broadcast
+- **difficulty_multipliers**:
+  - **description**: Both GetMaxHealth and GetMaxShield apply game-mode-dependent multipliers. Mode 1 (Easy?) uses global at 0xB16DCC, Mode 2 (Hard?) uses 0xB16DC8. Additionally, player-specific multipliers from PlayerObject+0x360 sub-object are applied.
+  - **easy_multiplier_global**: 0xB16DCC
+  - **hard_multiplier_global**: 0xB16DC8
+  - **player_multiplier**:
+    - **health**: PlayerObj+0x360 -> sub+0x50
+    - **front_shield**: PlayerObj+0x360 -> sub+0x54
+    - **rear_shield**: PlayerObj+0x360 -> sub+0x54
+
+
+### Max Health System
+
+- **description**: GetMaxHealth reads the base max HP from GameObjectType, then applies difficulty multipliers and ability modifiers.
+- **function**:
+  - **rva**: 0x3727A0
+  - **ghidra_va**: 0x1403727A0
+- **formula**: max_hp = type->base_max_hp(+0xDCC) * difficulty_multiplier * player_multiplier * (1.0 + ability_bonus)
+- **base_hp_offset**: GameObjectType+0xDCC (float32)
+- **pseudocode**: float GetMaxHealth(GameObjectType* type, GameObjectClass* obj) {

+            base *= (bonus + 1.0f);
+        }
+    }
+    return base;
+}
+
+
+### Hardpoint System
+
+- **description**: Objects with hardpoints (obj+0x348 != 0xFF) route damage through the HardpointManager. The HardpointManager (QueryInterface 0x16) maintains an array of HardPointClass instances. Each hardpoint has its own HP, shields, and can be independently destroyed.
+- **detection_flag**: obj+0x348 (0xFF = no hardpoints / direct HP, other = has hardpoints)
+- **manager_query**: QueryInterface(0x16) -> HardpointManager
+- **count_function**:
+  - **rva**: 0x405300
+  - **ghidra_va**: 0x140405300
+  - **reads**: [manager+0x28]+0x110 -> +0x18 (int count)
+- **get_hardpoint**:
+  - **rva**: 0x4052D0
+  - **ghidra_va**: 0x1404052D0
+- **hull_ratio_via_hardpoints**:
+  - **function**:
+    - **rva**: 0x405230
+    - **ghidra_va**: 0x140405230
+  - **description**: Iterates all hardpoints and calls GetHullPercentage (0x396DF0) on each. Used for aggregate health display.
+- **hardpoint_damage_routing**: When Take_Damage_PropertyDispatch detects obj+0x348 != 0xFF, it routes damage to individual hardpoints rather than the parent object's HP directly. The HardpointFire function (0x387F50) handles per-hardpoint HP reduction and station level loss notifications.
+- **station_level_loss**: When a hardpoint's HP reaches 0, FUN_140387F50 checks for space station level changes and broadcasts TEXT_ENEMY_SPACE_STATION_LEVEL_LOST or TEXT_FRIENDLY_SPACE_STATION_LEVEL_LOST.
+
+
+### Weapon Fire System
+
+- **description**: The weapon firing system is driven by CombatantBehaviorClass and its children (BaseCombatantClass, CompanyCombatantClass, SquadronCombatantClass). The fire control dispatch at 0x38D730 manages target acquisition, invulnerability pre-checks, weapon selection, and projectile spawning.
+- **fire_control_dispatch**:
+  - **rva**: 0x38D730
+  - **ghidra_va**: 0x14038D730
+  - **description**: Master fire control function. Checks: (1) target is enemy via FUN_1402824D0, (2) target is not invulnerable (obj+0x3A7), (3) target is not paused/immune (obj+0x3A0 & 0x42), (4) target's locomotor allows damage, (5) weapon range, (6) LOS check, (7) game mode constraints. Then dispatches to appropriate fire behavior.
+  - **invulnerability_precheck**: if (target+0x3A7 == 1) return 0;  // target invulnerable, skip
+  - **status_precheck**: if (target+0x3A0 & 0x42) return 0;  // target has immunity flags
+- **weapon_tick**:
+  - **rva**: 0x387010
+  - **ghidra_va**: 0x140387010
+  - **description**: Per-frame weapon update. Checks weapon state, manages firing cooldown via delta-time accumulation (param_1+0x60), resolves fire animation model by name, and calls the actual fire function.
+  - **cooldown_mechanism**: delta_ticks = current_tick - last_fire_tick (param_1+0x60). When cooldown expires, calls fire via FUN_140381FF0.
+  - **fire_animation**: Resolves model name from weapon data (type+0x1C0 SSO string), loads via asset system, and plays fire animation.
+- **hardpoint_fire**:
+  - **rva**: 0x387F50
+  - **ghidra_va**: 0x140387F50
+  - **description**: Per-hardpoint damage application. Subtracts damage from hardpoint HP (param_1+0x28), manages hardpoint-level death (station level loss), and fires death-on-destruction effects.
+  - **hp_field**: param_1+0x28 (float, current hardpoint HP)
+  - **fire_rate**: Managed by weapon tick delta-time accumulation
+- **combatant_classes**:
+  - **CombatantBehaviorClass**:
+    - **rva_ctor**: 0x6383E0

+    - **ghidra_va**: 0x1406CBA40
+- **target_selection**:
+  - **description**: BaseCombatantClass vtable[34] (SelectTarget) evaluates targets by range, health ratio, and weapon type bitmask. The weapon bitmask is stored at target_type+0x1648.
+  - **weapon_bitmask_offset**: GameObjectType+0x1648

+  - **game_speed_scaling**: (float)DAT_140B0A320 / (float)DAT_140B0A340 — applied in AnimationDispatch (0x3A92F0)
+  - **berserker_check**: FUN_1403A92F0 checks BerserkerAbilityClass RTTI. If berserker active, damage type forced to 0x68 and param_7 set to 1.
+  - **combat_bonus_ability**:
+    - **class**: CombatBonusAbilityClass
+    - **address**: 0x1406F42D0
+    - **description**: Modifies 8 separate combat stats via FUN_14038C850: (1) max HP bonus, (2) damage bonus, (3) front shield bonus, (4) rear shield bonus, (5) rate modifier, (6) range modifier, (7) accuracy modifier, (8) additional modifier. After modifying max_hp, scales current HP proportionally: SetHP(obj, (new_max - old_max) + current_hp).
+    - **stat_offsets_in_ability_data**:
+      - **hp_bonus**: +0x00
+      - **damage_bonus**: +0x04
+      - **front_shield_bonus**: +0x08
+      - **rear_shield_bonus**: +0x0C
+      - **rate_modifier**: +0x10
+      - **range_modifier**: +0x14
+      - **accuracy_modifier**: +0x18
+      - **additional**: +0x1C
+  - **absorb_blaster_ability**:
+    - **class**: AbsorbBlasterAbilityClass
+    - **address**: 0x1406EE840
+    - **description**: Converts incoming damage to healing. Reads damage type from target type+0x1FF4. If compatible (damage_type & ~0x3 != 0), converts damage to HP: SetHP(obj, current_hp + type->heal_factor(+0x474) * ability_factor + flat_bonus). Only works against specific damage types.
+    - **heal_formula**: new_hp = current_hp + (type+0x474 * ability+0x04) + ability+0x08
+
+
+### Damage Visual Thresholds
+
+- **description**: Take_Damage_Impl checks two global damage thresholds to trigger visual model changes (switching from pristine to damaged to heavily damaged art).
+- **threshold_1**:
+  - **global_rva**: 0x803514
+  - **description**: First damage threshold multiplier (applied to max_hp). When HP crosses below max_hp * threshold, switch to 'damaged' model.
+- **threshold_2**:
+  - **global_rva**: 0x8007C0
+  - **description**: Second damage threshold multiplier. When HP crosses below max_hp * threshold, switch to 'heavily damaged' model.
+- **visual_level_function**:
+  - **rva**: 0x3AC290
+  - **ghidra_va**: 0x1403AC290
+- **visual_level_logic**: Iterates an array at type+0xEB0 (float thresholds) paired with type+0xEC8 (animation indices). Compares health_ratio against each threshold and selects the highest matching visual level.
+
+
+### Prevent Death System
+
+- **description**: The prevent-death flag at obj+0x3A1 bit 7 (mask 0x80) prevents a unit from dying through normal combat damage. When set, Take_Damage_Impl clamps HP to max(1.0, old_hp) instead of letting it reach 0. This is the 'unkillable but damageable' mode used by Set_Cannot_Be_Killed(true) in Lua.
+- **flag_offset**: obj+0x3A1
+- **flag_mask**: 0x80 (bit 7)
+- **implementation**: In Take_Damage_Impl: if (obj->hp <= 0 && (obj->flags_3A1 & 0x80)) { SetHP(obj, max(1.0f, old_hp)); }
+- **note**: Distinct from full invulnerability (obj+0x3A7). Prevent-death still allows damage; it just prevents the final kill.
+
+
+### Invulnerability System
+
+- **description**: Full invulnerability is a multi-layered system. The primary flag at obj+0x3A7 is checked ONLY by Take_Damage_Outer (0x38A350). Additional immunity flags at obj+0x3A0 bits 1 and 6 are checked by FireControl_Dispatch (0x38D730). Setting invulnerability properly requires calling Make_Invulnerable_Setter (0x3ABB80) which propagates to all hardpoints.
+- **primary_flag**: obj+0x3A7 (checked by Take_Damage_Outer)
+- **status_flags**: obj+0x3A0 & 0x42 (checked by FireControl_Dispatch — prevents targeting entirely)
+- **container_flags**: obj+0x381, obj+0x382, obj+0x388
+- **setter_function**:
+  - **rva**: 0x3ABB80
+  - **ghidra_va**: 0x1403ABB80
+- **cleanup_function**:
+  - **rva**: 0x3A56B0
+  - **ghidra_va**: 0x1403A56B0
+- **lua_binding**:
+  - **rva**: 0x5819E0
+  - **ghidra_va**: 0x1405819E0
+- **setter_actions**: 1. Get behavior via QueryInterface(1), 2. Notify game engine of invulnerability change, 3. Schedule timer event for invulnerability expiry, 4. Update behavior system invulnerability count, 5. If has hardpoints (obj+0x348 != 0xFF): iterate all hardpoints via QueryInterface(0x16) and recursively call Make_Invulnerable_Setter on each, 6. In space mode (game_mode == 2): adjust shield position offsets
+
+
+### Health Regeneration
+
+- **description**: Two regeneration systems exist: natural health regen and shield-linked regen. Both call SetHP directly, bypassing invulnerability checks.
+- **natural_regen**:
+  - **function_rva**: 0x5D70F0
+  - **ghidra_va**: 0x1405D70F0
+  - **description**: Periodic health regeneration. First call sets HP to 1.0 (revival?), subsequent ticks add regen_rate to current HP, clamped to max_hp.
+  - **formula**: new_hp = min(current_hp + regen_rate, max_hp)
+- **shield_linked_regen**:
+  - **function_rva**: 0x387010
+  - **description**: Shield regeneration ticks also affect hull HP via: new_hp = current_hp * ratio (from GetHullPercentage).
+- **periodic_heal**:
+  - **function_rva**: 0x71B560
+  - **ghidra_va**: 0x14071B560
+  - **description**: DrainLifeAbilityClass periodic heal. Adds heal_amount to current HP via SetHP.
+  - **formula**: new_hp = current_hp + heal_amount
+- **periodic_dot**:
+  - **function_rva**: 0x6F80D0
+  - **ghidra_va**: 0x1406F80D0
+  - **description**: Damage-over-time periodic ticks (burning, ion damage, etc.). Adds damage_amount to HP (negative for damage, positive for heal).
+  - **formula**: new_hp = current_hp + damage_amount
+

+
+
+### Damage Type System
+
+- **description**: Damage types are integer IDs used throughout the combat system. The AnimationDispatch function (0x3A92F0) uses damage type to select animation and handle Berserker override. Specific type IDs observed:
+- **known_types**:
+  - **0x00**: Default/Normal (triggers default path in AnimationDispatch)
+  - **0x05**: Special type 1 (falls through to default in AnimationDispatch switch)
+  - **0x06**: Special type 2 (triggers special ability search in AnimationDispatch — BerserkerAbilityClass check)
+  - **0x08**: Fire/Burn damage (death handler checks: selects death anim variant 0x0C)
+  - **0x68**: Berserker/Eat forced type (overrides all other types when Berserker active, or used by EatAttack)
+  - **0x74**: Construction/Build type (used by tactical building construction)
+- **type_resolved_by**: AnimationDispatch (0x3A92F0) uses FUN_140264A40 to query animation count for the given type, then FUN_1401FFB40 for random selection within count.
+- **berserker_override**: When AnimationDispatch detects the unit is in active fire-while-queued state (obj+0x100 -> +0x2CC != 0), it checks if current command is 0x68. If not, it iterates the ability list, dynamic_casts to BerserkerAbilityClass (RTTI), and if found, forces damage_type = 0x68.
+
+
+### Game Speed Scaling
+
+- **description**: Combat calculations are scaled by game speed to maintain consistent damage-per-second regardless of game speed setting.
+- **numerator_global**: DAT_140B0A320 (current frame counter or time)
+- **denominator_global**: DAT_140B0A340 (reference time base)
+- **formula**: time_scale = (float)DAT_140B0A320 / (float)DAT_140B0A340
+- **applied_in**: AnimationDispatch (0x3A92F0) passes time_scale to FUN_140265560 and FUN_140265490
+
+
+### Modding Interception Points
+
+- **description**: Recommended hooking points for combat mods, ordered by specificity.
+- **hooks**: {'name': 'SetHP (universal HP intercept)', 'rva': '0x3A89D0', 'aob': '40 53 48 83 EC 60 0F 29 74 24 50 0F 57 C0 F3 0F 10 71 5C', 'params': 'RCX=GameObjectClass*, XMM1=new_hp (float32)', 'use_case': 'Intercept ALL HP changes.

+
+### Relationships
+
+- **planet_object_to_data_pack**:
+  - **description**: A planet on the galactic map is a GameObjectClass with a PlanetaryBehaviorClass component. The behavior at +0x18 points to the parent GameObjectClass. The parent's field at [0x17*8]=+0xB8 points to the PlanetaryDataPackClass. The data pack holds ownership, trade routes, income, capture state, and corruption.
+  - **traversal**: planet_game_object -> [+0xB8] -> PlanetaryDataPackClass
+  - **alternative**: PlanetaryBehaviorClass.offset_0x18 -> GameObjectClass -> [+0xB8] -> PlanetaryDataPackClass
+- **planet_ownership**:
+  - **description**: Planet ownership is stored at PlanetaryDataPackClass+0x6C as a player_id (int32). This indexes into the PlayerListClass at DAT_140a16fd0. The owning player's faction is at PlayerObject+0x68. Ownership changes go through PlanetFactionChangeClass which updates both the data pack fields and notifies all players.
+  - **read_path**: planet_data+0x6C -> player_id -> PlayerList_FindByID(DAT_140a16fd0, player_id) -> PlayerObject
+  - **write_path**: PlanetFactionChange_Transfer (RVA 0x3FB040) -> writes planet_data+0x6C, fires signals
+- **fow_system**:
+  - **description**: The FOW system is per-player and per-game-mode. The active GameModeClass (at DAT_140b15418) stores an array of per-player FOW objects at offset 0x198. Each FOW object contains three parallel arrays (visibility, timer, output) indexed by grid cell. Lua functions Reveal/Reveal_All/Undo_Reveal_All/Temporary_Reveal are bound through LuaFOWRevealCommandClass. All require tactical mode (not galactic).
+  - **access_path**: DAT_140b15418 -> [+0x198] -> fow_array[player_id] -> FOWPlayerObject
+  - **grid_encoding**:
+    - **0x00**: fully fogged
+    - **0x01-0x0F**: fading (was revealed, decreasing visibility)
+    - **0x10-0xEE**: revealed (stable)
+    - **0xEF**: just-cleared marker (transition state)
+    - **0xFF**: fully visible (permanent or active unit vision)
+  - **tactical_only**: True
+  - **galactic_note**: In galactic mode, planet visibility is handled differently -- through the PlanetReachabilityClass and the per-player-planet-data map at PlanetaryDataPackClass+0xA0. The tactical FOW grid does not exist in galactic mode.
+- **trade_routes_adjacency**:
+  - **description**: Trade routes form the edges of the galactic map graph. Each planet's PlanetaryDataPackClass contains a DynamicVectorClass<TradeRouteLinkEntryClass> at byte offset ~0x50 that lists adjacent trade routes. The TradeRouteClass objects themselves are stored in a separate global list (DynamicVectorClass<TradeRouteClass*> destructor at RVA 0x4AE5E0). The GalacticPathFinderClass singleton uses these adjacency lists for pathfinding.
+  - **per_planet**: PlanetaryDataPackClass offset ~0x50 = DynamicVectorClass<TradeRouteLinkEntryClass>
+  - **global_list**: DynamicVectorClass<TradeRouteClass*> (destructor RVA 0x4AE5E0)
+- **galactic_perception**:
+  - **description**: The GalacticPerceptionSystemClass (constructor RVA 0x4E1880) manages what each player can see on the galactic map. This is separate from the tactical FOW system. Planet visibility in galactic mode uses FUN_1403a51e0 which iterates planet components and checks visibility per-player.
+  - **constructor_rva**: 0x4E1880

+### Open Questions
+
+- Exact planet list global: Planets are GameObjectClass instances managed by the galactic mode. The Get_All_Planets Lua function iterates them, but the actual global pointer to the 'planet list' container has not been isolated to a single RVA. It likely lives inside the GalacticModeClass instance (sub-object of GameModeClass) or is accessed via the FindPlanetClass lookup mechanism.
+- PlanetaryDataPackClass full size: Destructor analysis shows fields up to at least offset 0x350+ (self[0x34] = byte offset 0x1A0+), but the total size with all DynamicVector members is larger.
+- Trade route edge data: The TradeRouteLinkEntryClass internal structure (which planet it connects to, travel time, hyperlane type) needs runtime validation.
+- Galactic FOW vs tactical FOW: Galactic mode visibility is handled by GalacticPerceptionSystemClass and per-player planet data, NOT by the tactical FOW grid system. The exact galactic visibility structure needs further RE.
+- Planet position data: Where x/y/z galactic map coordinates are stored on the planet object. Likely inherited from GameObjectClass transform component.

+## RE Findings Detail
+
+**Analysis**: SWFOC Alamo Engine — Network/Multiplayer Protocol Documentation
+
+Reverse-engineered documentation of the multiplayer architecture, command event format, synchronization mechanism, and desync-relevant memory areas in Star Wars: Forces of Corruption (Alamo engine, x86_64 Steam build).
+
+- **Date**: 2026-04-04
+- **Analyst**: Agent 3G (Network/Multiplayer Protocol RE)
+
+
+### Architecture
+
+- **type**: peer_to_peer_lockstep
+- **summary**: The Alamo engine uses a deterministic lockstep architecture. All peers execute the same simulation independently, synchronizing only player commands (events). There is no authoritative server — every peer runs the full game simulation. The FrameSyncEventClass (event ID 17) acts as the lockstep barrier, and FrameInfoEventClass (event ID 0) exchanges per-frame metadata. PerformanceMetricsEventClass (event ID 18) likely carries timing/checksum data for desync detection.
+- **evidence**: FrameSyncEventClass inherits ScheduledEventClass -> EventClass, sets event_type_id = 0x11 (17). It is registered via EventFactoryClass<FrameSyncEventClass,17>. The name 'FrameSync' directly indicates lockstep frame synchronization., FrameInfoEventClass (event ID 0) is the lowest-numbered event and inherits directly from EventClass (not ScheduledEventClass), suggesting it is a meta/control event exchanged every frame., PerformanceMetricsEventClass (event ID 18 = 0x12) also inherits directly from EventClass (not ScheduledEventClass), indicating it is a non-gameplay control message — likely carrying frame timing and/or checksum data., All gameplay-affecting events (Attack, Move, Production, etc.) inherit from ScheduledEventClass, meaning they are queued and executed at a deterministic frame. This is the hallmark of lockstep: commands are scheduled for a future frame, then all peers execute them simultaneously., No 'Replicate', 'NetState', 'AuthoritativeServer', or state-replication classes were found. All discovered event classes are player commands, not state snapshots — confirming command-based lockstep rather than state replication., The GameModeClass constructor allocates a DynamicVectorClass<struct_DelayedEventStruct*> — a queue for events that must wait until their scheduled frame arrives.
+
+
+### Transport Layer
+
+- **summary**: Dual transport: Winsock (direct IP/LAN) and Steam Networking (online via Steam). Both implement an AsyncSocket interface, abstracted behind PacketHandlerClass which runs on its own thread.
+- **socket_implementations**:
+  - **SteamAsyncSocketImpl**:
+    - **constructor_rva**: 0x6b370
+    - **description**: Steam-based socket using Valve's ISteamNetworking relay. Wraps Steam P2P networking API. Initialized with linked list node (0x30 bytes) and 64-bit SteamID handle at offset 0x20.
+    - **inherits**: RefCountClass
+  - **WinsockAsyncSocketImpl**:
+    - **constructor_rva**: 0x227110
+    - **description**: Traditional Winsock socket for LAN/direct-IP games. Constructor takes a 16-byte param (likely sockaddr_in: IP + port). Calls WSAGetLastError (imported at 0x227400) for error handling.
+    - **inherits**: RefCountClass
+- **packet_handler**:
+  - **class**: PacketHandlerClass
+  - **destructor_rva**: 0x2054c0
+  - **description**: Thread-based packet processing engine. Inherits from ThreadClass. Uses Windows CriticalSection for thread safety, a mutex with 10-second timeout for shutdown synchronization, and a linked-list packet queue. Dispatches received packets to registered callback functions typed as: void(*)(PacketHandlerClass*, void*, IPAddressClass&). Also supports raw byte callbacks: bool(*)(unsigned char*, int, IPAddressClass*, void*).
+  - **threading_note**: PacketHandlerClass::~PacketHandlerClass logs 'ThreadLockMutexClass -- %s failed to obtain mutex within 10 seconds' — confirming it runs on a dedicated network thread separate from the game thread.
+- **packet_class**:
+  - **class**: PacketClass
+  - **constructor_rva**: 0x23bc40
+  - **description**: Network packet. Inherits from BitStreamClass (bit-level serialization) and MultiLinkedListMember (for queue management). Constructor takes (int size, longlong buffer). If buffer is null and size > 0, allocates its own buffer. The BitStreamClass base provides bit-granularity read/write with separate read and write cursors.
+  - **inherits**: BitStreamClass, MultiLinkedListMember, RefCountClass
+  - **serialization_format**: bit-packed via BitStreamClass — fields are written at arbitrary bit widths, not byte-aligned. This is typical for lockstep RTS games to minimize bandwidth.
+- **ip_address_class**:
+  - **class**: IPAddressClass
+  - **description**: Wraps an IP address. Used in packet dispatch callbacks and maintained in DynamicVectorClass<IPAddressClass> collections.
+- **broadcaster_class**:
+  - **class**: BroadcasterClass

+  - **inner_types**: BroadcasterClass::PacketIdentifierStruct
+- **connection_class**:
+  - **class**: ConnectionClass
+  - **description**: Represents a single peer connection. Stored in DynamicVectorClass<ConnectionClass*> managed by BroadcasterClass.
+- **packet_type_class**:
+  - **class**: PacketTypeClass
+  - **description**: Packet type registry with magic number validation. Contains DynamicVectorClass<PacketTypeClass::tPacketMagicStruct> — each packet type has a 'magic' identifier for protocol-level validation and dispatch.
+  - **inner_types**: PacketTypeClass::tPacketMagicStruct
+

+  - **inner_types**: InternetPlayerStruct::ClanStruct
+
+
+### Event System
+
+- **summary**: The command synchronization protocol is built on an event system. All player actions are encoded as Event objects with a numeric type ID, serialized via BitStreamClass into PacketClass packets, broadcast to all peers, and executed deterministically at a scheduled frame. The EventFactoryClass pattern uses template parameters <EventClass, TypeID> for registration.
+- **class_hierarchy**:
+  - **EventClass**:
+    - **constructor_rva**: 0x5126c0
+    - **description**: Base event class. Has a type ID at offset 0x8 (set in each subclass constructor), a linked-list entry for queue management, and a frame counter from a global source.
+    - **key_fields**: {'offset': '0x00', 'name': 'linked_list_entry', 'type': 'LinkedListEntryClass<EventClass>'}, {'offset': '0x08', 'name': 'event_type_id', 'type': 'int32', 'description': 'Numeric event type. Set in each subclass constructor. Matches the factory template parameter.'}
+  - **ScheduledEventClass**:
+    - **constructor_rva**: 0x512c50
+    - **inherits**: EventClass
+    - **description**: Event scheduled for execution at a specific future frame. Most gameplay events inherit from this, not raw EventClass. Contains a scheduled frame number at offset 0x0 (initialized to 0xFFFFFFFF = unscheduled).
+    - **key_fields**: {'offset': '0x00', 'name': 'scheduled_frame', 'type': 'int32', 'description': "Frame number at which this event should execute. 0xFFFFFFFF = not yet scheduled. 0x80000000 bit at offset 0x1c may be a 'processed' flag."}
+  - **EventQueueClass**:
+    - **constructor_rva**: 0x4b39e0
+    - **description**: Queue that holds events awaiting execution. Allocates a slot array sized from a global (DAT_140a16fb0 = likely max_players or max_events_per_frame). Events are dequeued and executed when their scheduled frame arrives.
+  - **BaseEventFactoryClass**:
+    - **constructor_rva**: 0x5960f0
+    - **description**: Base factory that registers event types. Constructor adds itself to a global DynamicVectorClass<BaseEventFactoryClass*> at DAT_140b36bc1, building the event type registry at static initialization time.
+- **event_catalog**:
+  - **_note**: Complete catalog of all 50+ event types. The type_id matches the EventFactoryClass template second parameter AND the value written to EventClass.offset_0x8 in each constructor. Events marked 'scheduled' inherit from ScheduledEventClass; 'immediate' inherit directly from EventClass.

+
+
+### Synchronization Mechanism
+
+- **summary**: Lockstep with deterministic execution. All peers process the same events at the same frame. Three control events (IDs 0, 17, 18) form the sync protocol.
+- **frame_sync_protocol**:
+  - **description**: Each simulation frame follows this sequence: (1) Exchange FrameInfoEventClass (ID 0) with frame metadata; (2) Wait for FrameSyncEventClass (ID 17) from all peers — this is the lockstep barrier; (3) Execute all ScheduledEvents whose scheduled_frame matches the current frame; (4) Exchange PerformanceMetricsEventClass (ID 18) with timing/checksum data.
+  - **lockstep_barrier**: FrameSyncEventClass (ID 17). The simulation cannot advance until all peers have confirmed their events for this frame. This is the classic lockstep 'ready' signal.
+  - **delayed_event_queue**: GameModeClass maintains a DynamicVectorClass<DelayedEventStruct*> — events that arrived but whose scheduled_frame has not yet been reached. They are held in this queue and executed when the frame counter reaches their scheduled_frame value.
+- **determinism_requirements**:
+  - **description**: For lockstep to work, all peers must produce identical simulation results from identical inputs. This means the engine must be fully deterministic: same floating-point math, same RNG sequences, same execution order.
+  - **implications_for_modding**: Any memory modification that changes gameplay state (HP, damage, position, unit counts, production queues) without going through the event system will cause a desync in multiplayer., Single-player mods that directly write to GameObjectClass fields (e.g., HP at offset 0x5C) are safe in SP but will immediately desync in MP., Visual-only modifications (camera position, UI elements, selection highlights) do NOT cause desyncs because they are not part of the deterministic simulation.
+- **sentinel_values**:
+  - **0x3FFFFF**: Unset/null object reference sentinel. Used extensively in event constructors (FleetManagement, Reinforce, Invade, SpecialAbility, etc.) to indicate 'no target selected'. This is likely an index into a 22-bit object ID space.
+  - **0xFFFFFFFF**: Unscheduled frame (ScheduledEventClass.scheduled_frame default) or invalid/null reference.
+  - **0xFFFFFFFE**: Special sentinel in FleetManagementEventClass offset 0x14 — possibly 'auto-assign' or 'any available'.
+
+
+### Desync Detection
+
+- **summary**: Desync detection is inferred from PerformanceMetricsEventClass (ID 18) and the deterministic lockstep architecture. The engine likely checksums key simulation state each frame and compares across peers.
+- **known_mechanisms**:
+  - **performance_metrics_event**:
+    - **event_id**: 18
+    - **class**: PerformanceMetricsEventClass
+    - **rva**: 0x4c1eb0
+    - **description**: Non-scheduled event (inherits EventClass directly) exchanged every frame. Despite the name 'PerformanceMetrics', in lockstep RTS engines this class typically carries: (1) frame timing data (for adaptive game speed), (2) state checksums (for desync detection). The fact that it is exchanged every frame and is NOT a ScheduledEvent confirms it is sync infrastructure, not gameplay.
+  - **frame_info_event**:
+    - **event_id**: 0
+    - **class**: FrameInfoEventClass
+    - **rva**: 0x4c1b00
+    - **description**: Frame metadata. Likely carries the current frame number and possibly a hash/checksum of the game state.
+- **what_would_be_checksummed**:
+  - **description**: Based on the event system and Alamo engine structure, the following simulation state is most likely included in per-frame checksums:
+  - **high_confidence**: Global game frame counter, RNG state (random number generator seed/state), Total unit count per player, Total credits/income per player, Production queue state
+  - **medium_confidence**: Unit positions (at least checksum of all positions), Unit HP values, Unit ownership (player IDs), Active ability timers, Planet control state (galactic mode)
+  - **low_confidence_but_possible**: Individual unit state checksums, AI decision state, Pathfinding state
+- **what_is_safe_to_modify_in_multiplayer**:
+  - **safe**: Camera position and zoom (not synchronized), UI state (selection highlights, tooltips, HUD layout), Sound/music settings, Visual effects (particle counts, texture quality), Fog of war reveal (local rendering only — but may still be detected by FoW state checksumming), ChatEventClass content (ID 16 — non-scheduled, social only)
+  - **unsafe_will_desync**: GameObjectClass.hp (offset 0x5C), GameObjectClass.owner_player_id (offset 0x58), GameObjectClass.object_id (offset 0x50), Any production queue modification, Any unit spawn/destroy outside the event system, Any credit/resource value change, Any RNG state modification, Any movement/position override that bypasses ScheduledEventClass
+
+
+### Game Mode System
+
+- **summary**: GameModeClass is the battle/map controller. LandModeClass extends it for ground battles. Both manage event processing and the delayed event queue.
+- **game_mode_class**:
+  - **class**: GameModeClass
+  - **constructor_rva**: 0x35a5e0
+  - **description**: Large struct (~0x60 * 8 bytes). Manages the tactical/galactic game state, event queue (DelayedEventStruct vector), objectives (ObjectiveStruct vector), game speed (float at 0x10+4 = 0x3F800000 = 1.0f default), and player-specific state arrays.
+  - **key_fields_observed**: Offset 0x10+4: game_speed float (default 1.0 = 0x3F800000), Offset 0x28*8: DynamicVectorClass<DelayedEventStruct*> — delayed event queue, Offset 0x2B*8: DynamicVectorClass<ObjectiveStruct>, Offset 0x37*8: DynamicVectorClass<int> — possibly player scores or frame counters, Offset 0x3B*8: DynamicVectorClass<DynamicVectorClass<GameObjectClass*>> — per-player object lists
+- **land_mode_class**:
+  - **class**: LandModeClass
+  - **constructor_rva**: 0x3b5210
+  - **inherits**: GameModeClass
+  - **description**: Ground battle mode. Extends GameModeClass with additional linked lists for ground-specific state and a HeroClashManagerClass at offset 0x3F0.
+
+
+### Key Addresses
+
+- **_note**: All addresses are absolute (image base 0x140000000). Subtract image base for RVA.
+- **event_factory_registry**: DAT_140b36bc1 — global DynamicVectorClass<BaseEventFactoryClass*> where all event factories register at static init
+- **max_event_slots**: DAT_140a16fb0 — global int used to size the EventQueueClass slot array and GameModeClass player arrays
+- **frame_counter_source**: FUN_140294a70 with DAT_140a16fd0 — called in EventClass constructor to get current frame number
+- **steam_peer_lobby_singleton**: SingletonInstance<SteamPeerLobbyClass> at static init 0x7e6450
+- **steam_lobby_dialog_singleton**: SingletonInstance<SteamLobbyDialogClass> at static init 0x7e6590
+- **steam_class_singleton**: SingletonInstance<SteamClass> at static init 0x7e6580
+
+
+### Open Questions
+
+- Exact checksum algorithm used for desync detection (could not locate a CRC/hash function directly referenced by PerformanceMetricsEventClass — needs runtime tracing)
+- Exact format of PerformanceMetricsEventClass payload (needs decompilation of its virtual Pack/Unpack methods, which are in the vtable)
+- Whether the engine supports 'late join' or only 'lobby start' (likely lobby-only given pure lockstep)
+- Maximum player count (the sentinel 0x3FFFFF = 22 bits suggests up to ~4M object IDs, but player count is likely 2-8 based on the 'max_event_slots' global)
+- Whether DebugEventClass (ID 11) is stripped in release builds or can be used to inject commands
+- The exact PacketTypeClass::tPacketMagicStruct format — likely a 4-byte magic + version for protocol handshake
+- Whether the game uses NAT punchthrough (likely via Steam relay) or requires port forwarding for Winsock mode

+## RE Findings Detail
+
+**Analysis**: SWFOC Alamo Engine - Production/Build System Reverse Engineering
+
+Complete documentation of the production pipeline, build queue, unit cap system, cost deduction, and build time calculation in the Alamo engine (Star Wars: Empire at War - Forces of Corruption). Derived from Ghidra static analysis of StarWarsG.exe (x86_64).
+
+- **Date**: 2026-04-04
+
+
+### Overview
+
+- **summary**: The Alamo engine production system is event-driven. When a player requests unit production, a ProductionEventClass (event ID 7) is created and queued. The engine validates prerequisites (tech level, cost, unit cap, build slot availability), then creates an ObjectUnderConstructionClass entry in the production queue. Build time is computed as a multi-factor formula. Credits are deducted up-front (negative delta to PlayerObject+0x70). When the countdown expires, the unit is spawned and ownership transferred.
+- **pipeline_stages**: 1. VALIDATION: CanProduce check (FUN_1402804d0) - 15+ prerequisite gates, 2. COST CHECK: GetAdjustedCost (FUN_140400240/FUN_1403711c0) - calculates modified cost, 3. UNIT CAP CHECK: CheckPopCap (FUN_1402ac320) - validates population capacity, 4. QUEUE ENTRY CREATION: ObjectUnderConstructionClass allocation (0x38 bytes), 5. COST DEDUCTION: AddCredits (FUN_14027f370) with negative cost value, 6. BUILD TIME CALCULATION: ComputeBuildTime (FUN_140400370) - 5-factor formula, 7. COUNTDOWN: ScheduledEventClass timer decrements per frame, 8. COMPLETION: ObjectUnderConstructionClass destructor spawns the unit

+# Save Format
+
+**File Extension**: .sav
+
+**Encoding**: binary little-endian
+
+**Chunk Format**: Westwood W3D-derived (8-byte header: id+size, bit31=sub-chunks)
+
+**Micro Chunk Header**: 2 bytes (id+size, max 255 data bytes)
+
+**Compression**: zlib linked but usage unconfirmed for saves
+
+**Chunk Writer Ctor**: 0x21FCC0
+
+**Chunk Reader Ctor**: 0x220280

+
+## RE Findings Detail
+
+**Analysis**: SWFOC Save File Format Specification
+
+Reverse-engineered save file format for Star Wars: Empire at War - Forces of Corruption (Alamo Engine, x86_64 Steam build). Derived from static analysis of StarWarsG.exe via Ghidra MCP.
+
+- **Date**: 2026-04-04
+- **Analyst**: Agent 3F (Claude)
+
+
+### File Format
+
+- **extension**: .sav
+- **default_directory**: %APPDATA%\Petroglyph\Empire at War - Forces of Corruption\Save\
+- **encoding**: binary, little-endian
+- **byte_order**: little-endian (x86)
+- **overall_structure**: Hierarchical chunk tree (Westwood/Petroglyph chunk format). No top-level file magic or version header -- the file begins directly with the root chunk. zlib compression (compress2/uncompress2) is linked but usage context is TBD.
+- **compression**:
+  - **library**: zlib (statically linked)
+  - **functions**:
+    - **compress2**: 0x1407A1470
+    - **uncompress2**: 0x1407A1590
+    - **deflateInit_**: 0x1407A3080
+    - **deflateInit2_**: 0x1407A2DF0
+    - **inflateInit_**: 0x1407A54F0
+    - **compress_block**: 0x1407A60A0
+  - **notes**: zlib is present and may wrap the chunk payload or the entire file. Alamo engine .meg/.alo files use the same chunk format without compression. Save files may be uncompressed chunk trees or have a thin zlib wrapper. A sample file is needed to confirm.
+- **checksum**:
+  - **method**: none found
+  - **notes**: No CRC or checksum functions were identified in the save path. The engine does not appear to verify file integrity on load -- it relies on the chunk structure being well-formed.
+
+
+### Chunk Format
+
+- **description**: The Alamo engine uses a two-tier chunk system inherited from Westwood Studios W3D format. 'Chunks' are large containers that nest, 'micro-chunks' are leaf data units within a chunk.
+- **chunk_header**:
+  - **size**: 8
+  - **layout**: {'offset': 0, 'type': 'uint32', 'name': 'chunk_id', 'description': 'Identifies the chunk type. Unique within context.'}, {'offset': 4, 'type': 'uint32', 'name': 'chunk_size', 'description': 'Size of the chunk data in bytes (excludes this 8-byte header). Bit 31 (0x80000000) is set if the chunk contains sub-chunks rather than raw data.'}
+  - **sub_chunk_flag**: chunk_size & 0x80000000 != 0 means this chunk contains nested sub-chunks. data_size = chunk_size & 0x7FFFFFFF.
+  - **nesting**: Chunks nest to arbitrary depth. The ChunkWriter/ChunkReader support up to 256 nesting levels (0x800 byte stack / 8 bytes per level).
+  - **rvas**:
+    - **ChunkWriterClass_ctor**: 0x14021FCC0
+    - **ChunkWriterClass_dtor**: 0x14021FDC0
+    - **ChunkWriterClass_Open_Chunk**: 0x14021FE20
+    - **ChunkWriterClass_Close_Chunk**: 0x14021FEB0
+    - **ChunkWriterClass_Write**: 0x1402200B0
+    - **ChunkWriterClass_Write_CString**: 0x140220140
+    - **ChunkReaderClass_ctor**: 0x140220280
+    - **ChunkReaderClass_dtor**: 0x140220370
+    - **ChunkReaderClass_Get_File_Size**: 0x1402203F0
+    - **ChunkReaderClass_Tell**: 0x140220460
+    - **ChunkReaderClass_Open_Chunk**: 0x1402204A0
+    - **ChunkReaderClass_Close_Chunk**: 0x140220520
+- **micro_chunk_header**:
+  - **size**: 2
+  - **layout**: {'offset': 0, 'type': 'uint8', 'name': 'micro_chunk_id', 'description': 'Identifies the micro-chunk type within its parent chunk.'}, {'offset': 1, 'type': 'uint8', 'name': 'micro_chunk_size', 'description': 'Size of the micro-chunk data in bytes (max 255). Excludes this 2-byte header.'}
+  - **max_data_size**: 255
+  - **notes**: Micro-chunks are leaf-level data containers. They cannot nest. The size byte is patched after all data is written (seek-back pattern).
+  - **rvas**:
+    - **ChunkWriterClass_Open_Micro_Chunk**: 0x14021FFA0
+    - **ChunkWriterClass_Close_Micro_Chunk**: 0x140220030
+
+
+### String Encoding
+
+- **save_names**:
+  - **type**: wchar_t (UTF-16LE)
+  - **notes**: Save game names are wide strings. The SaveGameStruct stores names as std::wstring (MSVC SSO, inline threshold 7 wchars / 14 bytes). The [AutoSave] sentinel is a 10-wchar wide string.
+- **in_file_strings**:
+  - **type**: null-terminated char (ASCII/ANSI)
+  - **notes**: ChunkWriterClass::Write_CString writes strlen+1 bytes (includes null terminator). Strings in save data (object type names, faction names, etc.) are single-byte null-terminated.
+
+
+### Io Layer

+
+
+### Predicted Save Structure
+
+- **description**: Based on the class hierarchy and serialization system, the save file is predicted to have this top-level structure. Chunk IDs are UNKNOWN without a sample file -- these are placeholders based on common Alamo engine patterns.
+- **tree**: {'chunk': 'ROOT (ID TBD)', 'contains_sub_chunks': True, 'children': [{'chunk': 'SAVE_HEADER (ID TBD)', 'data': ['save_name (wstring)', 'save_timestamp', 'mod_name', 'version_info', 'game_mode_id']}, {'chunk': 'PLAYER_DATA (ID TBD)', 'contains_sub_chunks': True, 'repeats': 'per player', 'children': [{'chunk': 'PLAYER_INFO', 'data': ['player_id', 'faction_name (cstring)', 'credits', 'tech_level', 'is_human', 'team_id']}, {'chunk': 'AI_STATE', 'data': ['AIDataPackClass serialized state']}]}, {'chunk': 'GALACTIC_MAP (ID TBD)', 'contains_sub_chunks': True, 'children': [{'chunk': 'PLANET (ID TBD)', 'repeats': 'per planet', 'contains_sub_chunks': True, 'children': [{'chunk': 'PLANET_INFO', 'data': ['planet_name (cstring)', 'owner_player_id', 'corruption_level']}, {'chunk': 'GROUND_UNITS', 'data': ['PersistentTacticalBuiltObjectStruct array']}, {'chunk': 'SPACE_UNITS', 'data': ['unit type references, counts']}, {'chunk': 'UPGRADES', 'data': ['PersistentUpgradeObjectStruct array']}, {'chunk': 'TRADE_ROUTES', 'data': ['TradeRouteLinkEntryClass array']}, {'chunk': 'VISIBILITY', 'data': ['fog of war modifiers per player']}]}]}, {'chunk': 'OBJECT_PERSISTENCE (ID TBD)', 'contains_sub_chunks': True, 'data': ['ObjectPersistenceClass::tPersistentUnit array -- per-object save state']}, {'chunk': 'STORY_STATE (ID TBD)', 'data': ['story flag completion, campaign progress']}]}
+- **confidence**: SPECULATIVE -- based on class hierarchy only. Actual chunk IDs and exact ordering require a sample .sav file hexdump.
+
+
+### Safely Editable Fields
+
+- **description**: Fields that can be edited with low risk if the chunk structure is preserved. All require maintaining correct chunk sizes.
+- **high_confidence**: credits (per player) -- int32, within a micro-chunk, planet_owner (per planet) -- int32, player index, tech_level (per player) -- int32
+- **medium_confidence**: unit_hp (per unit) -- float32, within PersistentTacticalBuiltObjectStruct, corruption_level (per planet) -- likely int32 or float32, ability_cooldown_timers -- float32 values in AbilityCountdownDataPackClass, superweapon_cooldowns -- float32 values in TacticalSuperWeaponDataPackClass
+- **dangerous**: save_name -- wstring, changing length will corrupt chunk sizes, object_id mappings -- SaveLoadClass::ObjectPointerPairClass references; corrupting these breaks all pointer resolution on load, Adding/removing units -- requires updating multiple linked structures (PlanetaryDataPackClass vectors, ObjectPersistenceClass, player unit lists), faction_name changes -- referenced by multiple systems, length changes corrupt chunks

+
+### Story Architecture Overview
+
+- **status**: CONFIRMED
+- **description**: The story system is built on a 3-layer hierarchy: StorySubPlotClass owns StoryEventClass instances, which inherit from SignalGeneratorClass. Events are stored in a CRC32-keyed hash table within each subplot. The system uses XML-driven story definitions parsed at load time, with events dispatched via a type-ID factory pattern.
+- **class_hierarchy**:
+  - **SignalGeneratorClass**: Base class providing signal/event notification infrastructure
+  - **StoryEventClass**: Base story event — inherits SignalGeneratorClass. Size >= 0x360 bytes. Contains 15+ MSVC SSO string fields for reward parameters, dialog text, etc.
+  - **StorySubPlotClass**: Container for events within a story plot. Inherits SignalGeneratorClass. Size >= 0x650 bytes. Owns a CRC32 hash table of events + 61 DynamicVectorClass<StoryEventClass*> slots (0x3D).
+  - **StoryEventWrapper**: Lua wrapper for StoryEventClass — exposed to script with 7 methods
+  - **StoryPlotWrapper**: Lua wrapper for StorySubPlotClass — exposed to script with 5 methods
+
+
+### Story Flag Storage
+
+- **status**: CONFIRMED
+- **mechanism**: CRC32 hash table within StorySubPlotClass
+- **description**: Story flags/events are NOT stored as simple bool/int flags. Instead, each StorySubPlotClass contains a hash table at +0x20 (linked list head pointer) using CRC32(strupr(event_name)) XOR 0xDEADBEEF as the bucket key. Events are looked up case-insensitively by name. Each event node stores the CRC32 at +0x10 and a pointer to the StoryEventClass at +0x18.
+- **hash_function**:
+  - **rva**: 0x215A30
+  - **name**: CRC32_Hash
+  - **description**: Standard CRC32 using a lookup table at DAT_140a14d20. Takes (byte* data, uint length, uint seed). Seed is inverted on entry and result.
+  - **status**: CONFIRMED
+- **event_lookup_function**:
+  - **rva**: 0x52EF90
+  - **name**: StorySubPlot_FindEventByName
+  - **description**: Looks up a StoryEventClass* by name string. Converts name to uppercase via _strupr, computes CRC32, XORs with 0xDEADBEEF, applies LCG (a=16807 c=0 m=2^31-1) for bucket index, walks linked list comparing CRC32 values.
+  - **bucket_formula**: bucket_index = LCG(CRC32(strupr(name)) ^ 0xDEADBEEF) & bucket_mask
+  - **lcg_constants**:
+    - **a**: 16807
+    - **m**: 2147483647
+    - **note**: Lehmer/Park-Miller MINSTD generator used for hash distribution
+  - **status**: CONFIRMED
+- **event_active_flag_offset**: 0x4C in StoryEventClass (byte) — set to 0 when event is reset/inactive
+- **subplot_hash_table_offset**: +0x20 (linked list root pointer within StorySubPlotClass)
+- **subplot_bucket_array_offset**: +0x30 (bucket array pointer), +0x48 (bucket mask)
+
+
+### Event Type Enum
+
+- **status**: CONFIRMED
+- **description**: Event types are identified by integer IDs used in a switch/case factory at RVA 0x453310. The string-to-ID mapping is stored in a global std::map-like tree at DAT_140b30728, keyed by CRC32 of the uppercase type name string.
+- **factory_function_rva**: 0x453310
+- **factory_function_name**: StoryEvent_Factory_Create
+- **global_type_tree_address**: DAT_140b30728 (global pointer to std::map<CRC32, int> root node)

+
+### Reward Dispatch System
+
+- **status**: CONFIRMED
+- **description**: Rewards are NOT dispatched via a big switch/case. Instead, each StoryEventClass stores a reward_type as an integer at offset +0x3C (relative to event data start, i.e., after the base class header). The reward type is resolved from a string name via a global std::map tree at DAT_140b30728 using CRC32 lookup. The same tree is used for both event types and reward types.
+- **reward_type_resolver_rva**: 0x45C3F0
+- **reward_type_resolver_name**: ResolveRewardTypeFromString
+- **reward_type_resolver_description**: Takes a null-terminated string, computes CRC32, searches the global tree (red-black tree rooted at DAT_140b30728) for a matching node. Returns the integer value from node+0x20 (the enum value). Returns 0 if not found.
+- **global_type_tree_rva**: 0xB30728
+- **reward_type_offset_in_event**: +0x3C from StoryEventClass data start
+- **set_reward_type_lua_rva**: 0x73EEF0
+- **set_reward_type_lua_name**: StoryEventWrapper::Set_Reward_Type
+- **set_reward_parameter_lua_rva**: 0x73ECA0
+- **set_reward_parameter_lua_name**: StoryEventWrapper::Set_Reward_Parameter
+- **reward_parameter_storage**: StoryEventClass data offsets +0x50 through +0x190 — array of MSVC SSO strings at 0x20 stride, indexed by parameter number. Up to 14 reward parameters.
+- **known_reward_type_strings**: Note: The actual string->int mappings are populated at runtime from XML data definitions., Common reward type names from modding community documentation include:, CYCLOPEAN_REVEAL_ALL, GIVE_MONEY, REMOVE_UNIT, SPAWN_HERO, SWITCH_SIDES,, TRIGGER_EVENT, SET_FLAG, DISABLE_UNIT, ENABLE_UNIT, LOCK_PLANET,, FLASH_PLANET, SET_TECH_LEVEL, DUAL_FLASH, DISABLE_BRANCH, ENABLE_BRANCH,, VICTORY, DEFEAT, SPEECH, TUTORIAL, STORY_TRIGGER, FORCE_RETREAT, etc., These are NOT hardcoded in the binary — they are CRC32-hashed from XML at load time.
+
+
+### Fire Story Event Mechanism
+
+- **status**: CONFIRMED
+- **description**: Story events are NOT fired via a single 'Fire_Story_Event' function. Instead, the LuaScriptClass::GetEvent global function (type_id=0x3D=61) is registered as the 'GetEvent' Lua global, which wraps StoryPlotWrapper::Get_Event. The actual Lua Story_Event() and Story_Event_Trigger() are registered elsewhere in the game-mode-specific Lua binding setup (not in LuaScriptClass base). Events fire through the SignalGeneratorClass signal system.
+- **lua_global_registration**:
+  - **function_name**: GetEvent
+  - **registered_at_rva**: 0x2567B0
+  - **description**: LuaScriptClass::RegisterGlobals registers 'GetEvent' as a global Lua function that wraps the story event lookup. The GetEvent object at +0xD8 in LuaScriptClass holds the 0x3D event type count.

+### How Story Flags Are Checked During Gameplay
+
+- **status**: CONFIRMED
+- **description**: Story flags are checked through the StoryEventFlagClass (event type 0x2C). When the story system evaluates events each tick, it iterates through the 61 type-indexed DynamicVectorClass arrays in the StorySubPlotClass. For type 0x2C (flag events), it checks whether the named flag has been set. Flags are set via the Set_Story_Flag Lua function which fires a story event of type FLAG. The CheckStoryFlagClass (RTTI confirmed) is a separate class used in the condition evaluation chain. The actual flag storage is within the event hash table itself — a flag 'exists and is active' is determined by the event's active byte at +0x4C being non-zero.
+- **flag_event_type_id**: 0x2C
+- **flag_class**: StoryEventFlagClass
+- **check_class**: CheckStoryFlagClass
+- **flow**: 1. Lua calls Set_Story_Flag('FLAG_NAME') or Check_Story_Flag('FLAG_NAME'), 2. This triggers a story event of type FLAG (0x2C) or queries the event hash table, 3. StorySubPlot_FindEventByName converts the name to uppercase, computes CRC32, 4. CRC32 XOR 0xDEADBEEF, then LCG for bucket index, 5. Walks the linked list in that bucket comparing CRC32 values, 6. If found, reads the active flag at event+0x4C, 7. For Set: sets event+0x4C to non-zero and triggers dependent events, 8. For Check: returns whether event+0x4C is non-zero
+
+
+### How Rewards Are Dispatched
+
+- **status**: CONFIRMED
+- **description**: When a story event completes (all conditions met), the reward system reads the reward type ID from the event (+0x3C) and the reward parameters from the string array at +0x50. The reward type was parsed from XML at load time via ResolveRewardTypeFromString (0x45C3F0) which hashes the reward type name string and looks it up in the global type tree. Reward dispatch is handled through the event's virtual function table — each concrete event subclass can override the reward execution method. The reward parameters (up to 14 strings at 0x20 stride) provide the data needed for the reward (unit type names, credit amounts, planet names, etc.).
+- **flow**: 1. Event conditions are met (checked via per-type virtual methods), 2. Event reads reward_type_id from +0x3C, 3. Event reads reward parameters from +0x50..+0x190 (up to 14 SSO strings), 4. Reward execution dispatched via virtual function table on the event, 5. Specific reward logic (spawn unit, give money, etc.) uses the string params
+

+  - **description**: Registered as a method on the LuaScriptClass Lua object
+
+
+### Signal System
+
+- **status**: CONFIRMED
+- **description**: Both StoryEventClass and StorySubPlotClass inherit from SignalGeneratorClass, which provides a publish-subscribe notification system. Events signal their state changes (triggered, completed, reset) to listeners. The SignalDispatcherClass is a singleton that routes signals between generators and listeners. SignalListenerClass instances (e.g., in StorySubPlotClass) subscribe to events and react when they fire.

+
+### Struct Layouts (VERIFIED via live CE MCP)
+| Struct | Fields Mapped | Live-Verified? |
+|--------|--------------|----------------|

+**Total confirmed: ~56 functions with exact name + RVA from binary**
+
+### Functions Community Docs Have That We DON'T (Gaps to Fill)
+
+Based on the Focumentation wiki and eaw-emmyluadoc, these are Lua functions documented by the community that we have NOT yet found RVAs for:
+
+**High Priority (trainer/helper-relevant) — from Imperialware + Community:**
+- `Find_Player(faction_name)` — get player object by faction name string. CRITICAL for helper bridge.
+- `SpawnList(unit_table, position, owner, allow_ai, delete_after)` — spawn MULTIPLE units at once. Better than Reinforce_Unit for batch spawns.
+- `Object.Despawn()` — remove an object from the game. No RVA found yet.
+- `Planet.Change_Owner(player)` — change planet ownership in GC. No RVA found yet.
+- `Sleep(seconds)` — coroutine yield. Essential for helper scripts with delays.
+- `TestValid(object)` — check if object ref is still alive. Prevents crashes.
+- `Object.Is_Human()` — on PlayerWrapper, returns true for human player. CONFIRMS our +0x62 flag finding.
+- `Object.Get_Enemy()` — on PlayerWrapper, returns enemy player list.
+- `Set_Hull` — NOT in binary (confirmed). Hull must be set via SetHP at C++ level.
+- `ReinforceList` — likely same as SpawnList? Community uses both names.
+
+**Medium Priority (abilities/unit control) — from Imperialware:**
+- `Object.Has_Ability(ability_name)` — check if unit has specific ability
+- `Object.Is_Ability_Ready(ability_name)` — check ability cooldown state
+- `Object.Reset_Ability_Counter()` — reset ability cooldown
+- `Object.Face_Immediate(target)` — instant rotation (Teleport_And_Face alternative)
+- `Object.Hide(bool)` — show/hide object
+- `Object.Get_Planet_Location()` — which planet an object is at (GC mode)
+- `Hide_Sub_Object(unit, flag, sub_name)` — hide sub-objects (e.g., "Shield" mesh)
+- `Create_Thread(func_name)` — Lua coroutine creation
+- `GameRandom(min, max)` — random number
+- `ScriptExit()` — terminate script
+
+**Low Priority (UI/debug):**
+- `Add_Radar_Blip(pos, name)` / `Remove_Radar_Blip(name)` — radar markers
+- `Object.Set_Check_Contested_Space(bool)` — toggle space contest check
+- Various cinematic camera functions (we found most already)
+
+**KEY INSIGHT from Imperialware:** It has ZERO memory offsets. It's purely file-based (XML modding + Lua script injection, requires game restart). Our binary RE is the ONLY source of runtime memory offsets for this game. Imperialware's value is confirming Lua function names/signatures and demonstrating the spawning pattern.
+
+---
+
+## 3. What Our RE Found That Community Docs DON'T Cover
+
+**These are UNIQUE contributions from our binary RE that aren't in any community source:**
+
+### Internal C++ Architecture
+- **QueryInterface component system** — full pseudocode, 8 query types mapped, component_lookup_table at +0x332
+- **Parent/sub-object traversal chain** — [obj+0x335] → [obj+0x278] → parent, with deep nesting loop recipe
+- **SetHP caller graph** — all 18 callers mapped, proving SetHP is the ONLY HP write path
+- **RTTI class hierarchy** — 2,919 classes with inheritance trees, vtable RVAs, virtual method counts
+- **LuaMemberFunctionWrapper<T> registration mechanism** — how wrapper classes register methods on Lua userdata
+- **Lua 5.0.2 C API wrapper RVAs** — lua_pushstring, lua_newtable, etc. compiled into the binary
+- **lua_State* location candidates** — TheEvaluatorScriptManagerClass singleton at 0x5E77E0
+
+### Memory Layout Details
+- **PlayerObject+0x62** = local player flag (1 = YOU) — NOT in any community doc
+- **PlayerObject+0x37** = playable faction flag — NOT in any community doc
+- **PlayerObject+0x48** = actual slot index (corrects KB's wrong +0x04) — NOT in any community doc
+- **GameObjectClass vtable RVA 0x8661B8** — exact vtable address for runtime object identification
+- **Parent component index at +0x335** — sub-object ownership resolution shortcut
+- **Container reference at +0x2B0** — invulnerability propagation chain
+
+### AOB Signatures
+All AOB signatures in signatures_phase2.json are original binary RE work — not available anywhere else:
+- SetHP prologue: `40 53 48 83 EC 60 0F 29 74 24 50 0F 57 C0 F3 0F 10 71 5C`
+- AddCredits prologue: `48 89 5C 24 08 57 48 83 EC 40 0F 29 74 24 30 41 0F B6 F8...`
+- SetSpeedOverride: `48 8B 81 A8 00 00 00 48 85 C0 74 ?? 89 90 A0 02 00 00...`
+- SetTechLevel: `56 57 41 54 48 83 EC 40 8B C2 48 89 5C 24 60...`
+
+### CE Bugs Discovered
+- `getRTTIClassName()` broken for x64 image-relative RTTI (COL sig=1)
+- `vtQword` scan cannot find large addresses
+- Neither is documented anywhere in the CE community
+
+---
+
+## 4. Practical Impact — What Saves Us Future Work
+
+### Things We Do NOT Need to Research
+Thanks to our Phase 1-2 RE + runtime CE session:
+
+1. **Owner detection** — SOLVED. PlayerArray at 0xA16FF0, local player at +0x62. No more scanning.
+2. **HP manipulation** — SOLVED. SetHP at 0x3A89D0, single write path, 18 callers mapped.
+3. **Credits** — SOLVED. PlayerObject+0x70 (float), AddCredits at 0x27F370.
+4. **Tech level** — SOLVED. PlayerObject+0x84 (int32), SetTechLevel at 0x288980.
+5. **Speed override** — SOLVED. obj+0xA8→locomotor, +0x29C flag, +0x2A0 value.
+6. **Hero respawn** — SOLVED. Global at RVA 0xB169F0.
+7. **Faction names** — SOLVED. PlayerObject+0x68 → string pointer.
+8. **Unit type identification** — SOLVED. obj+0x298 → GameObjectType → +0xF8 name.
+9. **Sub-object ownership** — SOLVED. Parent chain walk via +0x335/+0x278.
+10. **Invulnerability** — SOLVED. Make_Invulnerable_Setter at 0x3ABB80 (proper way), SetHP hook (practical way).
+
+### Things That Still Need Research (Phase 3 Candidates)
+1. **Fog of War pointer** — not found. Community docs mention `Fog_Of_War` as a Lua global but no internal address.
+2. **Selected unit pointer** — the game's "currently selected unit" global. Trainer uses AOB signatures for UI mirror values but the direct pointer would be more robust.
+3. **Game speed multiplier global** — the trainer profile has `game_speed: 0` (unresolved). Need to find the actual global.
+4. **Damage multiplier injection** — DealDamage vfunc on CombatantBehaviorClass (vtable 0x8B21D0). Needs decompilation of specific vfunc slots.
+5. **Lua state pointer extraction** — TheEvaluatorScriptManagerClass at 0x5E77E0 likely holds the lua_State*. Extracting it would enable calling any Lua function from the CT table.
+6. **Income rate multiplier** — the `FUN_1404B0500()+0x20` reference from the KB needs validation.
+7. **Planet ownership** — galactic map planet structs for planet switching features.
+
+### What Imperialware Could Contribute
+If the Imperialware project is still accessible:
+- **Spawning implementation** — how it calls Spawn_Unit/Reinforce from C# via Lua injection
+- **Mod roster parsing** — how it reads unit lists from any mod's XML
+- **Memory offset validation** — if it has known offsets for the 32-bit build, comparing against our 64-bit findings validates the struct layout migration
+
+### What PetroglyphTools Could Replace
+- **MEG file reading** — our editor has a custom implementation; PetroglyphTools NuGet package could replace it
+- **DAT localization parsing** — same
+- **Game detection/launch** — process locator patterns
+
+---
+
+## 5. Knowledge Base Update Recommendations
+
+### alamo_engine_kb.json Corrections Needed
+1. **PlayerObject+0x04** → mark as WRONG or remove. Actual slot index is at +0x48.
+2. **Add new fields**: +0x37 (playable flag), +0x48 (slot index), +0x62 (local player flag)
+3. **Update PlayerObject description** to note the 3-layer identity system: +0x37 (playable), +0x62 (local), +0x68 (faction name)
+
+### signatures_phase2.json Additions
+1. Add SetHP AOB: `40 53 48 83 EC 60 0F 29 74 24 50 0F 57 C0 F3 0F 10 71 5C`
+2. All signatures verified unique in module
+
+### lua_binding_map.json Enrichment
+1. Cross-reference parameter semantics from eaw-emmyluadoc
+2. Add missing function RVAs for Despawn, Get_Faction, ReinforceList
+3. Document scope restrictions (tactical-only vs any-mode) from community docs
+

+# SWFOC Save File Editor Specification
+
+## Status: FIRST PASS -- Binary Analysis Complete, No Sample File Validated
+
+This document describes what can be edited in Star Wars: Empire at War - Forces of Corruption
+save files (.sav), based on reverse engineering of StarWarsG.exe (x86_64 Steam build) via
+Ghidra. **No save editor exists in the modding community -- this is uncharted territory.**
+
+**Critical caveat:** No actual .sav sample file was available on disk during this analysis.
+The chunk IDs and exact serialization order are derived from class structure and code flow,
+not from hexdump validation. The first step before building an editor is obtaining and
+hex-dumping an actual save file.
+
+---
+
+## File Format Summary
+
+The save file uses the **Westwood/Petroglyph chunk format**, the same binary container used
+for .alo, .ala, and other Alamo engine files. There is no file-level magic number or version
+header -- the file begins directly with the first chunk.
+
+### Chunk Header (8 bytes)
+```
+Offset  Type    Name
+0x00    uint32  chunk_id        -- identifies chunk type
+0x04    uint32  chunk_size      -- data size in bytes (bit 31 = has sub-chunks)
+```
+
+- If `chunk_size & 0x80000000`, the chunk contains nested sub-chunks, not raw data
+- Actual data size = `chunk_size & 0x7FFFFFFF`
+- Chunks nest to arbitrary depth (up to 256 levels)
+
+### Micro-Chunk Header (2 bytes)
+```
+Offset  Type    Name
+0x00    uint8   micro_chunk_id  -- identifies field within parent chunk
+0x01    uint8   micro_chunk_size -- data size (max 255 bytes)
+```
+
+Micro-chunks are leaf-level data containers inside a chunk. They hold individual fields
+(an int, a float, a short string). They cannot nest.
+
+### String Encoding
+- **In-file strings**: null-terminated ASCII/ANSI (strlen+1 bytes written including null)
+- **Save names**: UTF-16LE wide strings (wchar_t, std::wstring with MSVC SSO)
+
+### Compression
+zlib is statically linked (compress2 at RVA 0x7A1470, uncompress2 at RVA 0x7A1590).
+Whether saves are zlib-wrapped or raw chunk trees is **TBD until a sample file is examined**.
+If compressed, the signature bytes 0x78 0x9C or 0x78 0x01 will appear near the file start.
+
+### Checksum
+No CRC or checksum calculation was found in the save path. The engine trusts the chunk
+structure. This is good news for editing -- no integrity check to bypass.
+
+---
+
+## Editable Fields
+
+### SAFE TO EDIT (high confidence)
+
+These are scalar values in micro-chunks. As long as the micro-chunk size byte is preserved
+(the value fits in the same number of bytes), editing is safe.
+
+| Field | Type | Location | Notes |
+|-------|------|----------|-------|
+| Player credits | int32 | Player data chunk, micro-chunk | Per-player currency |
+| Planet owner | int32 | Planet chunk, micro-chunk | Player index (0-based) |
+| Tech level | int32 | Player data chunk | Per-player technology level |
+| Unit HP | float32 | Per-unit persistent state | Current hitpoints |
+
+### MODERATELY SAFE (medium confidence)
+
+These require understanding the surrounding data but are still scalar edits.
+
+| Field | Type | Location | Notes |
+|-------|------|----------|-------|
+| Corruption level | int32/float32 | Planet chunk | Underworld corruption state |
+| Ability cooldowns | float32 | AbilityCountdownDataPackClass | Timer values, set to 0 to reset |
+| Superweapon timers | float32 | TacticalSuperWeaponDataPackClass | Cooldown remaining |
+| Shield state | float32 | BaseShieldDataPackClass | Shield HP/recharge state |
+| Visibility/fog | bitmask | PlanetaryDataPackClass | Per-player fog of war |
+
+### DANGEROUS -- DO NOT EDIT WITHOUT FULL PARSER
+
+| Field | Risk | Why |
+|-------|------|-----|
+| Save name (wstring) | HIGH | Changing length corrupts all parent chunk sizes |
+| Object ID mappings | CRITICAL | SaveLoadClass::ObjectPointerPairClass -- pointer resolution table. Corrupting this breaks ALL object references on load |
+| Adding/removing units | CRITICAL | Requires updating: PlanetaryDataPackClass vectors, ObjectPersistenceClass entries, player unit lists, linked list pointers |
+| Faction names | HIGH | Referenced by multiple systems, length-prefixed in context |
+| Chunk structure itself | CRITICAL | Moving, reordering, or resizing chunks without updating all parent sizes will corrupt the file |
+
+---
+
+## Architecture for a Save Editor
+
+### Phase 1: Parser (read-only)
+
+Build a chunk tree parser first. This is straightforward:
+
+```
+function parse_chunk_tree(stream):
+    while stream.has_data():
+        chunk_id = read_uint32(stream)
+        raw_size = read_uint32(stream)
+        has_children = (raw_size & 0x80000000) != 0
+        data_size = raw_size & 0x7FFFFFFF
+        
+        if has_children:
+            children = parse_chunk_tree(stream.slice(data_size))
+            yield Chunk(id=chunk_id, children=children)
+        else:
+            data = stream.read(data_size)
+            micro_chunks = parse_micro_chunks(data)
+            yield Chunk(id=chunk_id, data=data, micro_chunks=micro_chunks)
+
+function parse_micro_chunks(data):
+    offset = 0
+    while offset < len(data):
+        mc_id = data[offset]
+        mc_size = data[offset + 1]
+        mc_data = data[offset + 2 : offset + 2 + mc_size]
+        yield MicroChunk(id=mc_id, data=mc_data)
+        offset += 2 + mc_size
+```
+
+### Phase 2: Chunk ID Catalog
+
+With a parsed tree, catalog chunk IDs by examining multiple save files:
+1. Save at different campaign points
+2. Diff the chunk trees to identify which chunks change
+3. Map chunk IDs to game concepts (players, planets, units)
+4. Build a lookup table: chunk_id -> human-readable name
+
+### Phase 3: Field Editor
+
+For scalar fields within micro-chunks:
+1. Navigate to the target micro-chunk
+2. Read the current value (interpret bytes as int32/float32/etc.)
+3. Write the new value (same byte count)
+4. No chunk size updates needed if the value size is unchanged
+
+For variable-length fields (strings):
+1. Calculate the size delta
+2. Update the micro-chunk size byte
+3. Update ALL parent chunk sizes up to the root
+4. Rewrite the file from the modified chunk tree
+
+### Phase 4: Structural Editor
+
+For adding/removing objects:
+1. Full round-trip: parse entire file -> modify tree -> serialize entire file
+2. Must update ObjectPointerPairClass mappings
+3. Must update all DynamicVector counts and contents
+4. This is the hardest part and requires understanding every chunk type
+
+---
+
+## Key RVAs for Hooking/Debugging
+
+These addresses (relative to module base 0x140000000) are useful for runtime
+debugging with x64dbg or Frida to capture actual save data.
+
+### Save Flow
+| Function | RVA | Purpose |
+|----------|-----|---------|
+| SaveGameEventClass::Execute | 0x48FC00 | Entry point when save is triggered |
+| Save dispatch function ptr | global at 0xB313D8 | Actual save execution |
+| SaveGameEventClass::ctor | 0x48FA80 | Save event creation |
+
+### Chunk I/O
+| Function | RVA | Purpose |
+|----------|-----|---------|
+| ChunkWriter::Open_Chunk | 0x21FE20 | Begin writing a chunk (logs chunk_id) |
+| ChunkWriter::Close_Chunk | 0x21FEB0 | End chunk (patches size) |
+| ChunkWriter::Open_Micro_Chunk | 0x21FFA0 | Begin micro-chunk (logs mc_id) |
+| ChunkWriter::Close_Micro_Chunk | 0x220030 | End micro-chunk (patches size) |
+| ChunkWriter::Write | 0x2200B0 | Write raw bytes |
+| ChunkWriter::Write_CString | 0x220140 | Write null-terminated string |
+| ChunkReader::Open_Chunk | 0x2204A0 | Read chunk header |
+| ChunkReader::Close_Chunk | 0x220520 | Skip remaining data, pop level |
+
+### File I/O
+| Function | RVA | Purpose |
+|----------|-----|---------|
+| FileClass::Open | 0x213600 | CreateFileA wrapper |
+| FileClass::dtor | 0x2132F0 | CloseHandle |
+
+### Serialization Primitives
+| Function | RVA | Purpose |
+|----------|-----|---------|
+| Write_Int | 0x2046F0 | Write integer to stream |
+| Read_Int | 0x2043B0 | Read integer from stream |
+| Write_String | 0x204FB0 | Write wstring to stream |
+| Read_String | 0x204AD0 | Read wstring from stream |
+
+---
+
+## Recommended Next Steps
+
+### 1. Obtain a Sample Save File
+Play a galactic conquest game, save it, and locate the .sav file at:
+`%APPDATA%\Petroglyph\Empire at War - Forces of Corruption\Save\`
+
+### 2. Hexdump and Validate Format
+```bash
+xxd -l 512 savefile.sav
+```
+Look for:
+- Does it start with a chunk header (8 bytes: id + size)?
+- Or does it start with zlib magic (0x78 0x9C)?
+- Are there recognizable strings (planet names, faction names)?
+
+### 3. Runtime Trace with Frida
+Hook ChunkWriter::Open_Chunk to log all chunk_ids in write order:
+```javascript
+Interceptor.attach(base.add(0x21FE20), {
+    onEnter(args) {
+        console.log("Open_Chunk: id=" + args[1].toInt32().toString(16) + 
+                     " depth=" + Memory.readS32(args[0].add(0x10)));
+    }
+});
+```
+This will produce the complete chunk ID catalog with nesting depth.
+
+### 4. Hook Open_Micro_Chunk Similarly
+```javascript
+Interceptor.attach(base.add(0x21FFA0), {
+    onEnter(args) {
+        console.log("Open_MicroChunk: id=" + args[1].toInt32().toString(16));
+    }
+});
+```
+
+### 5. Build the Parser
+With the chunk ID catalog from step 3, build a Python parser that reads
+the chunk tree and displays it in human-readable form. This is the
+foundation for all editing.
+
+---
+
+## Known Persistent Data Structures
+
+These classes are serialized into the save file. Each has virtual serialize/deserialize
+methods that emit micro-chunks.
+
+### Per-Planet (PlanetaryDataPackClass)
+- Built structures (PersistentTacticalBuiltObjectStruct)
+- Applied upgrades (PersistentUpgradeObjectStruct)
+- Hyperspace lane connections (LineLinkStruct)
+- Trade route state (TradeRouteLinkEntryClass)
+- Ground unit garrison (DynamicVector of GameObjectClass*)
+- Space unit garrison (DynamicVector of GameObjectClass*)
+- Type references (DynamicVector of GameObjectTypeClass*)
+- Fog of war (visibility modifiers per player)
+- Planet name (SSO string)
+
+### Per-Object (ObjectPersistenceClass::tPersistentUnit)
+- Object type reference
+- DataPack state for each attached behavior/component
+- Position, rotation, health state
+
+### Per-Player
+- Credits, tech level, faction name
+- AI state (AIDataPackClass) for computer players
+- Diplomatic relations, team assignments
+- Build queues, production state
+
+### Global
+- Game mode (galactic conquest, campaign)
+- Turn counter / game time
+- Story flag state (campaign progress)
+- Random seed state
+
+---
+
+## Comparison with Other Alamo Engine Formats
+
+The .sav format shares the exact same chunk infrastructure as:
+- **.alo** (3D model files) -- same ChunkReader/ChunkWriter
+- **.ala** (animation files) -- same chunk headers
+- **.meg** (archive files) -- different container but same engine
+
+Existing tools like Mike.nl's AloViewer or the Petroglyph modding tools parse
+the chunk format for .alo files. Their chunk parsing code can be adapted for
+.sav files -- only the chunk IDs and data interpretation differ.

+# SWFOC Snapshot Format (v1 + v2)
+
+> **Version history**
+>
+> - **v1** — original format. Magic `SWFOCSNAPv1`. No explicit local-player
+>   slot in section 1; the reader infers it as the first player.
+> - **v2** — added 2026-04-08. Magic `SWFOCSNAPv2`. Adds an explicit
+>   `local_slot: uint32` immediately after `player_count` in section 1.
+>   `UINT32_MAX` (`0xFFFFFFFF`) means "no local player".
+>
+> Both `swfoc_lua_bridge/replay_harness.cpp` and the synthetic generator
+> `swfoc_lua_bridge/make_test_snapshot.py` accept either version. The
+> writer in `lua_bridge.cpp::Lua_DumpState` emits v2 by default. Pass
+> `--v1` to `make_test_snapshot.py` to emit a v1 snapshot for back-compat
+> regression tests. Both readers cross-check the magic against the
+> `format_version` field and reject mismatched headers.
+
+## Purpose
+
+The `.swfocsnap` file format captures a single point-in-time view of SWFOC game state from a running `StarWarsG.exe` so it can be replayed offline by editor tests and analysis tools. The capture side lives inside `powrprof.dll` (the SWFOC Lua bridge) as the Lua helper `SWFOC_DumpState(path)`. The replay side lives outside this document.
+
+A snapshot is **not** a full memory dump. It stores only the fields the replay harness needs to mock out player slots, Lua state counts, object-type populations, and whitelisted global bindings. Everything is little-endian, tightly packed, and fixed-width where possible so a C, C++, C#, Python, or Rust reader can parse it with `memcpy`-style reads.
+
+## Byte Order and Padding Rules
+
+- All multi-byte integers are **little-endian**.
+- All floats are **IEEE 754 64-bit** (no 32-bit floats at the file format level; the capture widens player credits from `float` to `double`).
+- All ASCII strings in fixed-width fields are **null-padded, not null-terminated** — a 64-byte faction field containing `"REBEL"` has bytes `52 45 42 45 4C 00 00 ... 00`.
+- The header is aligned to 8 bytes. Sections are **not** padded between each other; each section is immediately followed by the next section header.
+
+## File Layout
+
+```
++----------------------------+  offset 0
+|        FILE HEADER         |  68 bytes total
++----------------------------+  offset 0x44
+|        SECTION 1           |  variable

++----------------------------+  end of file

+
+## File Header (68 bytes)
+
+| Offset | Size | Type                | Field                | Description                                                                 |

+| 0x10   | 4    | uint32 LE           | format_version       | `1` for legacy snapshots, `2` for current. Reader cross-checks against magic and rejects mismatch. |
+| 0x14   | 8    | uint64 LE           | capture_timestamp_ms | Unix epoch milliseconds at the instant the capture started                  |
+| 0x1C   | 32   | uint8[32]           | engine_build_hash    | SHA-256 digest of `StarWarsG.exe`, or all zeros if unavailable              |

+
+Total header size: **68 bytes**. The first section header begins at file offset `0x44`. The header is not 8-aligned at the end, but every fixed-size field inside it is naturally aligned for its type, and each section's payload does its own alignment internally (see Section 4 where the `uint64` raw value is explicitly 8-aligned via its `pad[7]` field).
+
+Magic is checked byte-for-byte. A reader that does not see exactly these 16 bytes must reject the file.
+
+## Section Framing
+
+Every section after the header is preceded by an 8-byte section header:
+
+| Offset | Size | Type       | Field          | Description                                                |

+| 0x04   | 4    | uint32 LE  | section_length | Number of payload bytes that follow, **not** including this header |
+
+Defined section IDs:
+
+| ID          | Name             | Description                                               |
+|-------------|------------------|-----------------------------------------------------------|
+| `0x00000001`| player_array     | Player slot snapshots                                     |
+| `0x00000002`| lua_state_registry| Count and pointer list of registered Lua states          |
+| `0x00000003`| object_catalog   | Summary of named game object types and their populations  |
+| `0x00000004`| global_registry  | Whitelisted Lua globals                                    |
+| `0x00000005`| metadata         | Key/value metadata strings                                |
+| `0xFFFFFFFF`| end              | End-of-file marker; payload is a 4-byte CRC32             |
+
+Sections must appear in ascending ID order in a v1 snapshot. The end marker must be last. Readers must skip unknown section IDs by advancing `section_length` bytes.
+
+## Section 1 — `player_array` (ID 0x00000001)
+
+Payload (v2 — current):
+
+```
+uint32 player_count
+uint32 local_slot            // v2 only — UINT32_MAX = no local player
+for i in 0..player_count:
+    uint32  slot             // 0-based slot index
+    char    faction[64]      // null-padded ASCII
+    float64 credits          // widened from engine float32
+    int32   tech_level
+    char    player_name[64]  // null-padded ASCII
+```
+
+Payload (v1 — legacy, no `local_slot`):
+
+```
+uint32 player_count
+for i in 0..player_count:
+    uint32  slot             // 0-based slot index
+    char    faction[64]      // null-padded ASCII
+    float64 credits          // widened from engine float32
+    int32   tech_level
+    char    player_name[64]  // null-padded ASCII
+```
+
+Per-player record size: `4 + 64 + 8 + 4 + 64 = 144 bytes`.
+
+Section length:
+- v1: `4 + 144 * player_count`
+- v2: `4 + 4 + 144 * player_count` (extra `local_slot: uint32`)
+
+Notes:
+- `faction` comes from `PlayerObj.FactionName` (engine offset `+0x68`, `char*`).
+- `credits` is read from `PlayerObj.Credits` (engine offset `+0x70`, `float`) and widened to `double`.
+- `tech_level` is read from `PlayerObj.TechLevel` (engine offset `+0x84`, `int32`).
+- `player_name` is reserved for future display-name data. v1 capture writes an empty string (all zero bytes) because the engine does not expose a player display name the bridge can safely dereference. Readers must not assume this field is populated.
+- The capture bounds-checks `player_count` to `[0, 8]`. If the engine reports more than 8 players, only the first 8 are written and the count is clamped.
+
+## Section 2 — `lua_state_registry` (ID 0x00000002)
+
+Payload:
+
+```
+uint32 state_count
+for i in 0..state_count:
+    uint64 state_pointer
+```
+
+Section length: `4 + 8 * state_count`.
+
+Notes:
+- `state_pointer` values are the raw `lua_State*` addresses captured inside the running game. They are useless for replay (they point into a foreign address space) but they tell downstream tooling how many Lua states the engine spawned and whether the count matches what we expect from the mod under test.
+- The capture bounds-checks `state_count` to `[0, 1024]` to defend against corrupted vectors.
+
+## Section 3 — `object_catalog` (ID 0x00000003)
+
+Payload:
+
+```
+uint32 type_count
+for i in 0..type_count:
+    char   type_name[64]       // null-padded ASCII
+    uint32 instance_count
+```
+
+Per-type record size: `64 + 4 = 68 bytes`.
+
+Section length: `4 + 68 * type_count`.
+
+Notes:
+- This is a **summary**, not the full object dump. The replay harness uses it to size its mock object lists — e.g., "the replay needs to simulate 12 TIE_Fighter instances so filter queries return the right count".
+- `type_name` matches the SWFOC `GameObject_Type` name strings (e.g. `Nebulon_B_Frigate`, `TIE_Fighter`).
+- `instance_count` is the number of live instances of that type at capture time. Zero is valid and means the type is known but currently has no instances.
+- v1 capture walks a fixed whitelist of well-known names. Future versions may add discovery; the format supports up to `UINT32_MAX` entries.
+
+## Section 4 — `global_registry` (ID 0x00000004)
+
+Payload:
+
+```
+uint32 global_count
+for i in 0..global_count:
+    char   name[64]         // null-padded ASCII
+    uint8  lua_type          // 0=nil, 1=boolean, 3=number, 4=string, 6=function, 7=userdata
+    uint8  pad[7]            // zero padding so raw_value is 8-aligned
+    uint64 raw_value_or_ptr  // number = IEEE 754 bit pattern, string = pointer, function = C closure addr
+```
+
+Per-global record size: `64 + 1 + 7 + 8 = 80 bytes`.
+
+Section length: `4 + 80 * global_count`.
+
+Allowed `lua_type` values follow the Lua 5.0.2 type tags from `lua_types.h`:
+
+| Value | Lua type           |
+|-------|--------------------|
+| 0     | `LUA_TNIL`         |
+| 1     | `LUA_TBOOLEAN`     |
+| 3     | `LUA_TNUMBER`      |

+
+Values 2 (`LUA_TLIGHTUSERDATA`), 5 (`LUA_TTABLE`), and 8 (`LUA_TTHREAD`) are reserved and not written by v1 capture.
+
+Whitelisted global names (the capture writes one record per name that resolves to any non-nil value, plus the SWFOC_* helpers, and one record per name that is nil so the replay can verify absence):
+
+- `Find_Player`
+- `Find_Object_Type`
+- `Find_All_Objects_Of_Type`
+- `Spawn_Unit`
+- `Story_Event`
+- `Letter_Box_On`
+- `Suspend_AI`

+For `LUA_TNUMBER` globals, `raw_value_or_ptr` holds the raw IEEE 754 bit pattern of the number (read via `memcpy` from a `double`). For `LUA_TSTRING` globals, it holds the captured string's engine pointer (useless for replay but diagnostic). For `LUA_TFUNCTION` globals, it holds the C function pointer if the binding is a C closure, otherwise zero. For `LUA_TNIL`, it is zero.
+
+## Section 5 — `metadata` (ID 0x00000005)
+
+Payload:
+
+```
+uint32 entry_count
+for i in 0..entry_count:
+    uint16 key_length
+    char   key[key_length]
+    uint16 value_length
+    char   value[value_length]
+```
+
+Neither `key` nor `value` is null-terminated. There is no padding between entries.
+
+Section length: sum of the field sizes above.
+
+Required keys in v1 (capture must emit all of them, in any order):
+
+| Key                    | Example value                |
+|------------------------|------------------------------|
+| `capture_method`       | `powrprof_dll`               |
+| `mod_name`             | `unknown`                    |
+| `mod_version`          | `unknown`                    |
+| `swfoc_bridge_version` | `1.0`                        |
+
+Readers must tolerate additional unknown keys.
+
+## Section 11 — `selected_units` (ID 0x0000000B, added 2026-04-23)
+
+OPTIONAL. Emitted by `SWFOC_DumpState` only when the selection reader
+resolves a non-empty selection (i.e. tactical battle with units selected).
+Enables replay-side tests to observe what the user had selected at capture
+time without re-walking the live selection pointer chain.
+
+Payload:
+
+```
+uint32 count
+for i in 0..count:
+    uint64 obj_addr   // absolute GameObject pointer captured live
+```
+
+Section length: `4 + 8 * count`. `count` is bounded to `64` by the writer
+(mirrors `RVA::Selection::kMaxSelectionCount`).
+
+## Section 12 — `unit_detail` (ID 0x0000000C, added 2026-04-23)
+
+OPTIONAL. Emitted alongside section 11. One record per selected obj_addr;
+carries the state reads Task 99 (hardpoint-behavior invulnerability) and
+Task 100 (damage-path hunt) need for autonomous offline iteration.
+
+Payload:
+
+```
+uint32 unit_count
+for i in 0..unit_count:
+    uint64  obj_addr
+    char    type_name[64]       // reserved (writer currently emits "")
+    int32   owner_slot          // GameObj+0x58
+    float32 hull                // GameObj+0x5C
+    float32 max_hull            // reserved; writer emits 0.0 (engine layout unstable)
+    uint8   invuln_flag         // GameObj+0x3A7 (display flag, no gameplay effect)
+    uint8   prevent_death       // GameObj+0x3A1 (bit 0x80 is the capture of interest)
+    uint8   reserved[6]         // zero padding, 8-byte alignment buffer
+    uint32  hardpoint_count
+    uint32  hardpoint_index[hardpoint_count]  // indices derived from GameObj.ComponentArray walk
+```
+
+Per-unit fixed portion: 92 bytes. `hardpoint_count` is bounded to 32 by
+the writer. Behavior-object lists are NOT in this section — see section 13.
+
+## Section 13 — `behavior_attach` (ID 0x0000000D, added 2026-04-23)
+
+OPTIONAL. Flat list of (obj_addr, hp_index, behavior_name) triples that
+the replay harness applies on top of section 12's unit records. Current
+writer emits `entry_count=0` because the engine does not expose a
+"list behaviors on hardpoint" read path yet — once Task 100's IDA
+investigation uncovers it, the writer populates this section.
+
+Payload:
+
+```
+uint32 entry_count
+for i in 0..entry_count:
+    uint64 obj_addr
+    uint32 hp_index
+    char   behavior_name[32]    // e.g. "INVULNERABLE"
+```
+
+Per-entry size: 44 bytes. Readers silently skip triples that reference
+obj_addrs not present in section 12 (forward-compat: a capture that emits
+behaviors for units outside the selection does not fail loading).
+
+## End Marker
+
+After the last content section, the file ends with a 12-byte record:
+
+| Offset | Size | Type       | Field          | Description                                               |
+|--------|------|------------|----------------|-----------------------------------------------------------|
+| 0x00   | 4    | uint32 LE  | section_id     | Always `0xFFFFFFFF`                                       |
+| 0x04   | 4    | uint32 LE  | section_length | Always `4`                                                |
+| 0x08   | 4    | uint32 LE  | crc32          | CRC32 of every byte from offset 0 up to and including `section_length` (i.e., the 8 bytes `FF FF FF FF 04 00 00 00` are covered by the CRC; the 4-byte CRC itself is not) |
+
+CRC32 is computed with the standard polynomial `0xEDB88320`, initial value `0xFFFFFFFF`, final XOR `0xFFFFFFFF`, and byte-reflected input/output (the same variant used by zlib, PKZIP, and `crc32()` in Python's `zlib` module).
+
+## Example Hex Dump (Minimal Snapshot)
+
+The smallest meaningful v1 snapshot has the header, an empty `player_array`, an empty `lua_state_registry`, an empty `object_catalog`, an empty `global_registry`, a `metadata` section with only the four required keys, and the end marker. With `capture_timestamp_ms = 0x1234567890ABCDEF`, `engine_build_hash = all zeros`, `game_mode = 4` (menu), and the metadata set to the example values above, the file looks like this (offsets on the left, bytes in the middle, annotation on the right):
+

+```
+
+Total file size: `0x00EE = 238 bytes` for a fully-empty snapshot with the required metadata.
+
+The actual CRC32 value depends on the concrete bytes produced by the capture, so it is shown as `XX XX XX XX` above.
+
+## Reader Checklist
+
+A compliant reader MUST:
+
+1. Verify the magic matches one of `SWFOCSNAPv1` or `SWFOCSNAPv2` exactly.
+2. Verify `format_version` is `1` (legacy) or `2` (current). Reject the file if the magic and the version disagree (e.g. `SWFOCSNAPv1` header with `format_version=2`).
+3. When `format_version >= 2`, read the additional `local_slot: uint32` field in section 1 immediately after `player_count`. Treat `UINT32_MAX` (`0xFFFFFFFF`) as "no local player".
+4. When `format_version == 1`, derive the local slot from `players[0].slot` after the per-player loop completes (legacy convention).
+5. Skip unknown section IDs by consuming `section_length` bytes.
+6. Recompute the CRC32 over all bytes before the end-marker CRC field and compare. Reject the file on mismatch.
+7. Treat all fixed-width strings as null-padded and stop interpreting at the first null byte.
+8. Treat `capture_timestamp_ms = 0` as "unknown" but still accept the file.
+
+## Writer Guarantees
+
+The capture writer (`SWFOC_DumpState`) guarantees:
+
+1. The header is written exactly once at offset 0.
+2. Sections appear in ascending ID order, no duplicates.
+3. `player_count` is clamped to at most 8.
+4. `state_count` is clamped to at most 1024.
+5. The `capture_timestamp_ms` field is populated via `GetSystemTimeAsFileTime` converted to Unix milliseconds.
+6. The end marker and CRC32 are written last. If the writer is interrupted before the end marker is emitted, the file is truncated and invalid — readers will detect this via the CRC mismatch and/or missing end marker.

+// tactical modes (1, 2, 4) but is silently guarded out in galactic
+// mode (3) by sub_14028AF60 at 0x14028AF60. The 2026-04-10 live-game
+// test showed this split-brain: v1 returns 1 (success) but +0x62
+// stays pinned to the old slot because Switch_Sides never ran its
+// body. See knowledge-base/faction_switch_full_anatomy_2026-04-11.md
+// for the full anatomy.
+//
+// v2's strategy is to do the three writes the engine does at the
+// byte level, unconditionally, regardless of game mode:
+//   1. Clear +0x62 = 0 on every slot except target
+//   2. Set +0x62 = 1 on target
+//   3. Write PlayerListClass+0x30 = target
+// Then call GameMode_RefreshLocalPlayerSubsystems on the active game
+// mode to refresh camera / HUD / selection / input router. This is
+// the same refresh path the engine's own `switch_player` console
+// command uses after Switch_Sides (via sub_14001FB30 -> sub_1402B59B0).
+//
+// In tactical modes the manual sweep is redundant with what
+// Switch_Sides would have done, but it is idempotent and cheap. In
+// galactic mode the sweep IS the fix. Mode detection is NOT
+// performed — guessing the mode adds failure modes for no benefit.
+//
+// Limitations (see investigation doc, "Limitations" section):
+//   - Does NOT update PlayerObject+0x360 (AIPlayerClass pointer).
+//     If the AI keeps driving the swapped-to faction, the writer for
+//     +0x360 is a next-session task.
+//   - Does NOT update any fog-of-war / viewport global directly.

+// human's faction?" — and the operator's live test on 2026-04-25
+// confirmed the prediction (post-switch, BOTH the human and an AI
+// were issuing orders to the swapped-to faction).
+//
+// v3 does the byte sweep + +0x30 write + subsystem refresh exactly
+// like v2 (so behaviour stays identical when no AI brain is attached),
+// then SWAPS the +0x360 pointers between the old and new slot. Effect:
+//   - The AI that was driving the new slot moves to the old slot
+//     (so the operator's old faction now has an AI controller)
+//   - The new slot's +0x360 becomes whatever the old slot held

+//
+// Memory-neutral: the same AIPlayerClass instance gets re-pointed
+// from one slot to another. No leak, no realloc.
+//
+// Verified ledger entry: struct_player_ai_player_ptr (PlayerClass+0x360)
+// is in verified_facts.json with confidence VERIFIED (single-tool
+// Ghidra). The cross-validation gate is acceptable here because:
+//   (a) the offset has independent corroboration in the per-system
+//       JSON dumps (re-findings/playerobject_complete.json);
+//   (b) a wrong write to +0x360 produces a logged diagnostic, not a
+//       silent corruption — every read/write logs the before+after
+//       pointer values so a misalignment is visible immediately.

+// Calls any method `method_name` on a Lua object expression with the
+// caller-supplied argument list spliced verbatim. Composes
+// `(<obj_expr>):(<method_name>)(<args_expr>)` and dispatches via DoString.
+//
+// One wire, infinite methods. Operator examples:
+//   SWFOC_CallObjMethodLua("Find_Player(\"REBEL\")", "Give_Money", "5000")
+//   SWFOC_CallObjMethodLua("Find_First_Object(\"Empire_AT_AT\")", "Heal", "")
+//   SWFOC_CallObjMethodLua("Find_First_Object(\"Empire_AT_AT\")", "Enable_Behavior", "\"INVULNERABLE\", true")
+//
+// Bridge does NOT validate the method name or args — that's the engine's
+// Lua VM's job. Localhost-only (named pipe, max_instances=1) so untrusted
+// input isn't a concern; the operator is the caller. The dispatcher is
+// the GREATEST-COMMON-DENOMINATOR wire that lets the editor surface ANY
+// engine Lua API the operator can name, without needing to ship a
+// per-method bridge wire and catalog flip.
+//
+// Trade-off vs per-method wires (iter 100/107/108/109/110/111/112):
+// per-method wires give the catalog a typed surface with named badges,
+// which is operator-pleasing in the editor UI. The universal wire is

+//   ARCHITECTURAL FINDING: Take_Damage's `Src` (param 5) is a name string

+//   Sampled callers (sub_14005FE90, sub_14071DFF0, sub_140436920,

+//   Take_Damage detour CANNOT reliably extract the attacker player slot
+//   without dangerous stack-walking.
+//
+//   Implication for SWFOC_SetDamageMultiplier semantics:
+//     - g_dmgMult_global (applied to all damage when slot=-1 was passed
+//       to SWFOC_SetDamageMultiplier(-1, mult)) → IMPLEMENTABLE via a
+//       Take_Damage detour at this chokepoint. Reliable. Single hook.
+//     - g_dmgMult_perSlot[slot] (per-attacker semantics) → NOT
+//       IMPLEMENTABLE at Take_Damage. Needs detours at the ~58 caller
+//       sites that have an attacker context (e.g., weapon-fire paths).
+//       Defer to a future arc that pins those caller layers.
+//
+//   Recommended near-term implementation (iter 96+):
+//     - Detour 0x1403A9E30. In the hook, scale `*damageValue` by
+//       g_dmgMult_global (loaded under g_dmgMultLock).
+//     - Documentation update: SWFOC_SetDamageMultiplier(slot, mult) with
+//       slot >= 0 stores per-slot but is INERT until the higher-layer
+//       detours land. slot == -1 stores g_dmgMult_global which IS LIVE.
+//     - Capability badge: emit SWFOC_SetDamageMultiplierGlobal as LIVE
+//       (new helper) while SWFOC_SetDamageMultiplier (the per-slot
+//       superset) stays MIXED with a note explaining the layered status.
+//
+// Until the detour + the badge split ship, the stored values are inert
+// from the game's perspective. Storage + chokepoint identification +

+"""Build a minimal valid .swfocsnap file for exercising swfoc_replay.exe.
+
+This mirrors the byte layout documented in SNAPSHOT_FORMAT.md. It is used by
+the replay harness smoke test; it is NOT a production capture tool.
+
+Format versions
+---------------
+- v1 (legacy, kept for backward-compat tests): no explicit local_slot;
+  the reader derives it from the first player.
+- v2 (default since 2026-04-08): adds an explicit ``local_slot: uint32``
+  in section 1 immediately after ``player_count``. ``UINT32_MAX`` means
+  "no local player".
+
+  v2 also defines OPTIONAL forward-compatible sections 6-10 that earlier
+  v2 readers may safely skip:
+
+  - section 6: ``planet_state``        per-planet corruption + ownership
+  - section 7: ``diplomacy``           pairwise faction relationships
+  - section 8: ``cooldowns``           per-unit-type ability cooldowns
+  - section 9: ``task_forces``         per-slot task force records
+  - section 10: ``object_owners``      per-instance unit ownership
+
+  These extensions added 2026-04-08 to support v5 service replay tests.
+  See ``swfoc_lua_bridge/SNAPSHOT_FORMAT.md`` for the byte layouts and
+  ``knowledge-base/replay_stub_gaps.md`` for the helper-by-helper map.
+
+CLI:
+    python make_test_snapshot.py <out>              # writes v2 (extended)
+    python make_test_snapshot.py <out> --v2-early   # writes v2 WITHOUT sections 6-10
+    python make_test_snapshot.py <out> --v1         # writes legacy v1
+
+The ``--v2-early`` flag models a snapshot captured during the brief window
+after the v2 magic was introduced but before sections 6-10 landed. It lets
+back-compat tests verify that a v2 reader handling a v2 file with only
+sections 1-5 still works (the "unknown section = skip" rule must catch
+readers of the newer format that encounter older v2 files without the
+extended sections).

+  * Support Visual Studio 2017 RC.
+
+- **v1.3.2.1 - 9 Nov 2015**  (Nuget package only)
+  * Fixed an insufficient support for Visual Studio 2015.
+
+- **v1.3.2 - 1 Nov 2015**
+  * Support Visual Studio 2015.
+  * Support MinGW.
+
+- **v1.3.2-beta3 - 21 Jul 2015**  (Nuget package only)
+  * Support MinGW. (Experimental)
+
+- **v1.3.2-beta2 - 18 May 2015**
+  * Fixed some subtle bugs. (Thanks to RaMMicHaeL)
+  * Added a helper function ```MH_StatusToString```. (Thanks to Jan Klass)
+
+- **v1.3.2-beta - 12 May 2015**
+  * Fixed a possible thread deadlock in x64 mode. (Thanks to Aleh Kazakevich)
+  * Reduced the footprint a little more.
+  * Support Visual Studio 2015 RC. (Experimental)
+
+- **v1.3.1.1 - 7 Apr 2015**  (Nuget package only)
+  * Support for WDK8.0 and 8.1.
+
+- **v1.3.1 - 19 Mar 2015**
+  * No major changes from v1.3.1-beta.
+
+- **v1.3.1-beta - 11 Mar 2015**
+  * Added a helper function ```MH_CreateHookApi```. (Thanks to uniskz).
+  * Fixed a false memory leak reported by some tools.
+  * Fixed a degradated compatibility issue.
+
+- **v1.3 - 13 Sep 2014**
+  * No major changes from v1.3-beta3.
+
+- **v1.3-beta3 - 31 Jul 2014**
+  * Fixed some small bugs.
+  * Improved the memory management.
+
+- **v1.3-beta2 - 21 Jul 2014**
+  * Changed the parameters to Windows-friendly types. (void* to LPVOID)
+  * Fixed some small bugs.
+  * Reorganized the source files.
+  * Reduced the footprint a little more.
+
+- **v1.3-beta - 17 Jul 2014**
+  * Rewrote in plain C to reduce the footprint and memory usage. (suggested by Andrey Unis)
+  * Simplified the overall code base to make it more readable and maintainable.
+  * Changed the license from 3-clause to 2-clause BSD License.
+
+- **v1.2 - 28 Sep 2013**
+  * Removed boost dependency ([jarredholman](https://github.com/jarredholman/minhook)).
+  * Fixed a small bug in the GetRelativeBranchDestination function ([pillbug99](http://www.codeproject.com/Messages/4058892/Small-Bug-Found.aspx)).
+  * Added the ```MH_RemoveHook``` function, which removes a hook created with the ```MH_CreateHook``` function.
+  * Added the following functions to enable or disable multiple hooks in one go: ```MH_QueueEnableHook```, ```MH_QueueDisableHook```, ```MH_ApplyQueued```. This is the preferred way of handling multiple hooks as every call to `MH_EnableHook` or `MH_DisableHook` suspends and resumes all threads.
+  * Made the functions ```MH_EnableHook``` and ```MH_DisableHook``` enable/disable all created hooks when the ```MH_ALL_HOOKS``` parameter is passed. This, too, is an efficient way of handling multiple hooks.
+  * If the target function is too small to be patched with a jump, MinHook tries to place the jump above the function. If that fails as well, the ```MH_CreateHook``` function returns ```MH_ERROR_UNSUPPORTED_FUNCTION```. This fixes an issue of hooking the LoadLibraryExW function on Windows 7 x64 ([reported by Obble](http://www.codeproject.com/Messages/4578613/Re-Bug-LoadLibraryExW-hook-fails-on-windows-2008-r.aspx)).
+
+- **v1.1 - 26 Nov 2009**
+  * Changed the interface to create a hook and a trampoline function in one go to prevent the detour function from being called before the trampoline function is created. ([reported by xliqz](http://www.codeproject.com/Messages/3280374/Unsafe.aspx))
+  * Shortened the function names from ```MinHook_*``` to ```MH_*``` to make them handier.
+
+- **v1.0 - 22 Nov 2009**
+  * Initial release.
+
+### Building MinHook - Using vcpkg
+
+You can download and install MinHook using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+
+    git clone https://github.com/microsoft/vcpkg
+    .\vcpkg\bootstrap-vcpkg.bat
+    .\vcpkg\vcpkg integrate install
+    .\vcpkg\vcpkg install minhook
+
+The MinHook port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.

+// replay_harness.cpp -- SWFOC Phase 6 offline replay harness.
+//
+// Standalone executable that loads a `.swfocsnap` file captured by the live
+// bridge (SWFOC_DumpState in lua_bridge.cpp), rebuilds the relevant slices of
+// game state in memory, embeds a Lua 5.0.2-shaped stub VM (reusing
+// fake_lua.cpp + fake_memory.cpp from the test harness), re-registers the
+// SWFOC_* helpers against the replay state, and hosts a named-pipe listener
+// on `\\.\pipe\swfoc_bridge_replay` that speaks the SAME protocol as the
+// live bridge.
+//
+// Build:
+//   x86_64-w64-mingw32-g++ -O2 -std=c++17 -static -o swfoc_replay.exe
+//       replay_harness.cpp fake_lua.cpp fake_memory.cpp -lws2_32
+//
+// Usage:
+//   swfoc_replay.exe <path-to-snapshot.swfocsnap>
+//
+// The live bridge continues to own `\\.\pipe\swfoc_bridge`; this harness
+// uses a distinct pipe name so it can run alongside the live game without
+// competing for the same pipe.

+//        is HEAP-allocated, so the live-test pointer 0x000002983d64b950 was

+//        address). This helper mirrors the in-bridge expression exactly so
+//        the harness can drive it over the hostile fixture vectors from the
+//        live-test ground truth.

+//        PIPE_CMD_MAX to 16384 and sizes g_pipeResult[PIPE_CMD_MAX]. The

+# swfoc_overlay — In-Game Overlay (Phase 1)
+
+In-game overlay DLL for SWFOC, designed to coexist with `powrprof.dll` (the
+existing Lua bridge) and provide a cleaner operator-facing surface than the
+desktop V2 editor. See `knowledge-base/overlay_design_2026-04-27.md` for the
+full architecture rationale.
+
+## Phase status (2026-04-27)
+
+### Phase 1 (iter 31) — DONE
+
+Buildable skeleton:
+- D3D9 vtable harvest + MinHook detours of `Present` + `Reset`.
+- F1 hotkey via worker-thread polling (no WndProc detour, no host-message-pump deadlock risk).
+- `IsVisible / SetVisible / ToggleVisible` API.
+- "Present frame=N visible=N" log to DebugView every 600 frames.
+
+### Phase 2-lite (iter 43) — DONE
+
+Minimum-viable visible render: an **amber badge** bottom-right when the
+overlay is toggled on. Proves the detour can paint geometry over the game
+without dependence on ImGui.
+
+- 160×32 amber rectangle (matches editor's `WarningForeground` brand colour).
+- ~70% alpha so the game stays partly visible underneath.
+- Pre-transformed-vertex format (`D3DFVF_XYZRHW | D3DFVF_DIFFUSE`) — no
+  projection matrix setup needed.
+- Saves + restores all touched render state (alpha blend, Z-enable, cull
+  mode, lighting, FVF) so we don't poison the host's subsequent draws.
+- ~60 LoC added; no new dependencies.
+
+### Phase 2-full — NEXT
+
+Vendor ImGui (Dear ImGui core + DX9 backend + Win32 backend) and
+replace the rectangle with a real panel showing operator-relevant state
+(local player, alive units, current planet, hotkeys). ~10-15 vendored
+files; tracked separately because of the size.
+
+### Phase 6 — DEFERRED
+
+Editor↔overlay IPC (second named pipe). The overlay can already call
+the existing bridge directly in-process; the editor pipe is only needed
+when overlay actions should reflect in the desktop UI in real-time.
+
+## Build
+
+Requires MinGW-w64 (`x86_64-w64-mingw32-g++`), same toolchain the bridge uses.
+
+```cmd
+cd swfoc_overlay
+build.bat
+```
+
+Output: `swfoc_overlay.dll` (~80 KB, statically linked, no DLL deps beyond
+`d3d9.dll` / `kernel32.dll` / `user32.dll`).
+
+## Install
+
+The DLL needs the OS loader to pick it up next to `StarWarsG.exe`. The bridge
+already takes `powrprof.dll`, so the overlay needs a *different* shim name.
+Candidates (any DLL the game's import table actually references):
+
+- `dwmapi.dll` — Desktop Window Manager API. Common; safe.
+- `dxva2.dll` — DirectX video acceleration. Safe if game doesn't use video.
+- `version.dll` — version-resource API. Almost universal.
+
+Pick one, rename `swfoc_overlay.dll` → `<chosen>.dll`, drop next to
+`StarWarsG.exe`. Final pick deferred to install testing once the
+`StarWarsG.exe` import table has been audited.
+
+## Verify Phase 1 + 2-lite
+
+1. Launch SWFOC.
+2. Alt-tab to **DebugView** (Sysinternals).
+3. Look for lines like:
+   ```
+   [swfoc_overlay] Install OK — F1 toggles visibility
+   [swfoc_overlay] Present frame=0 visible=0
+   [swfoc_overlay] Present frame=600 visible=0
+   ```
+4. Press **F1** in-game. The next frame log should show `visible=1` AND
+   an amber rectangle should appear in the bottom-right of the screen.
+5. Press F1 again — the rectangle disappears, log shows `visible=0`.
+
+If both behaviours match, Phase 1 + 2-lite are green. The hook fires every
+frame, visibility state toggles correctly, and the render path can paint
+geometry over the host's swap chain without breaking subsequent draws.
+
+## File map
+
+| File | Purpose |
+|---|---|
+| `dllmain.cpp` | DLL entry point, spawns bootstrap worker. |
+| `overlay.h` | Public surface (`Install/Uninstall/IsVisible/...`). |
+| `overlay.cpp` | D3D9 vtable harvest + MinHook detours + F1 poller. |
+| `build.bat` | MinGW-w64 build pipeline. |
+| `README.md` | This file. |
+
+## Next: Phase 2-full (ImGui)
+
+Replace the Phase 2-lite rectangle with a vendored ImGui panel.
+
+Vendoring shopping list (~15 files):
+- `imgui.cpp` + `imgui.h`
+- `imgui_draw.cpp` + `imgui_widgets.cpp` + `imgui_tables.cpp`
+- `imgui_internal.h` + `imconfig.h`
+- `imstb_rectpack.h` + `imstb_textedit.h` + `imstb_truetype.h`
+- `backends/imgui_impl_dx9.cpp` + `imgui_impl_dx9.h`
+- `backends/imgui_impl_win32.cpp` + `imgui_impl_win32.h`
+
+Done line: a panel saying "Hello, operator" with the current frame counter,
+visibility toggle indicator, and a "Phase 2-full landed at iter X" footer.
+
+Phase 2-full → Phase 3: HUD reading live state from the already-loaded
+`powrprof.dll` (in-process Lua, no IPC). Phase 3 → Phase 4: drag-to-spawn
+(camera projection matrix RE pin required first). Phase 4 → Phase 7:
+aesthetic polish + faction-tinted chrome.

+    // commands — both are the same blocking named-pipe round-trip, so they
+    // share one implementation rather than duplicating the pipe code.
+    //
+    // BLOCKING: performs synchronous CreateFile / WriteFile / ReadFile. Must be

+// dear imgui: Renderer Backend for DirectX9
+// This needs to be used along with a Platform Backend (e.g. Win32)
+
+// Implemented features:
+//  [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID!
+//  [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
+// Learn about Dear ImGui:
+// - FAQ                  https://dearimgui.com/faq
+// - Getting Started      https://dearimgui.com/getting-started
+// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
+// - Introduction, links and more at the top of imgui.cpp
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2024-10-07: DirectX9: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+//  2024-02-12: DirectX9: Using RGBA format when supported by the driver to avoid CPU side conversion. (#6575)
+//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
+//  2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
+//  2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+//  2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
+//  2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
+//  2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
+//  2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
+//  2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+//  2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+//  2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
+//  2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
+//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+//  2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
+//  2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+//  2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
+//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
+//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2024-07-08: Inputs: Fixed ImGuiMod_Super being mapped to VK_APPS instead of VK_LWIN||VK_RWIN. (#7768)
+//  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
+//  2023-09-25: Inputs: Synthesize key-down event on key-up for VK_SNAPSHOT / ImGuiKey_PrintScreen as Windows doesn't emit it (same behavior as GLFW/SDL).
+//  2023-09-07: Inputs: Added support for keyboard codepage conversion for when application is compiled in MBCS mode and using a non-Unicode window.
+//  2023-04-19: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
+//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen. (#2702)
+//  2023-02-15: Inputs: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse position over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
+//  2023-02-02: Inputs: Flipping WM_MOUSEHWHEEL (horizontal mouse-wheel) value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
+//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+//  2022-09-28: Inputs: Convert WM_CHAR values with MultiByteToWideChar() when window class was registered as MBCS (not Unicode).
+//  2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
+//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
+//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
+//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
+//  2022-01-17: Inputs: always update key mods next and before a key event (not in NewFrame) to fix input queue with very low framerates.
+//  2022-01-12: Inputs: Update mouse inputs using WM_MOUSEMOVE/WM_MOUSELEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
+//  2022-01-12: Inputs: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
+//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
+//  2021-12-16: Inputs: Fill VK_LCONTROL/VK_RCONTROL/VK_LSHIFT/VK_RSHIFT/VK_LMENU/VK_RMENU for completeness.
+//  2021-08-17: Calling io.AddFocusEvent() on WM_SETFOCUS/WM_KILLFOCUS messages.
+//  2021-08-02: Inputs: Fixed keyboard modifiers being reported when host window doesn't have focus.
+//  2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using TrackMouseEvent() to receive WM_MOUSELEAVE events).
+//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
+//  2021-06-08: Fixed ImGui_ImplWin32_EnableDpiAwareness() and ImGui_ImplWin32_GetDpiScaleForMonitor() to handle Windows 8.1/10 features without a manifest (per-monitor DPI, and properly calls SetProcessDpiAwareness() on 8.1).
+//  2021-03-23: Inputs: Clearing keyboard down array when losing focus (WM_KILLFOCUS).
+//  2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
+//  2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.
+//  2021-01-25: Inputs: Dynamically loading XInput DLL.
+//  2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
+//  2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)
+//  2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.
+//  2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.
+//  2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
+//  2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
+//  2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
+//  2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
+//  2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
+//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
+//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
+//  2018-06-10: Inputs: Fixed handling of mouse wheel messages to support fine position messages (typically sent by track-pads).

+//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+//  2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
+//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+//  2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
+//  2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
+//  2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.
+//  2017-10-23: Inputs: Using Win32 ::SetCapture/::GetCapture() to retrieve mouse positions outside the client area when dragging.

+// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications)
+// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
+
+// Implemented features:
+//  [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
+//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
+//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy VK_* values are obsolete since 1.87 and not supported since 1.91.5]
+//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

+// DEAR IMGUI COMPILE-TIME OPTIONS
+// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
+// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
+//-----------------------------------------------------------------------------
+// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
+// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
+//-----------------------------------------------------------------------------
+// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
+// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
+// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
+// Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using.
+//-----------------------------------------------------------------------------

+ MISSION STATEMENT
+ =================
+
+ - Easy to use to create code-driven and data-driven tools.
+ - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
+ - Easy to hack and improve.
+ - Minimize setup and maintenance.
+ - Minimize state storage on user side.
+ - Minimize state synchronization.
+ - Portable, minimize dependencies, run on target (consoles, phones, etc.).
+ - Efficient runtime and memory consumption.
+
+ Designed primarily for developers and content-creators, not the typical end-user!
+ Some of the current weaknesses (which we aim to address in the future) includes:
+
+ - Doesn't look fancy.
+ - Limited layout features, intricate layouts are typically crafted in code.
+
+
+ CONTROLS GUIDE
+ ==============
+
+ - MOUSE CONTROLS
+   - Mouse wheel:                   Scroll vertically.
+   - SHIFT+Mouse wheel:             Scroll horizontally.
+   - Click [X]:                     Close a window, available when 'bool* p_open' is passed to ImGui::Begin().
+   - Click ^, Double-Click title:   Collapse window.
+   - Drag on corner/border:         Resize window (double-click to auto fit window to its contents).
+   - Drag on any empty space:       Move window (unless io.ConfigWindowsMoveFromTitleBarOnly = true).
+   - Left-click outside popup:      Close popup stack (right-click over underlying popup: Partially close popup stack).
+
+ - TEXT EDITOR
+   - Hold SHIFT or Drag Mouse:      Select text.
+   - CTRL+Left/Right:               Word jump.
+   - CTRL+Shift+Left/Right:         Select words.
+   - CTRL+A or Double-Click:        Select All.
+   - CTRL+X, CTRL+C, CTRL+V:        Use OS clipboard.
+   - CTRL+Z, CTRL+Y:                Undo, Redo.
+   - ESCAPE:                        Revert text to its original value.
+   - On OSX, controls are automatically adjusted to match standard OSX text editing 2ts and behaviors.
+
+ - KEYBOARD CONTROLS
+   - Basic:
+     - Tab, SHIFT+Tab               Cycle through text editable fields.
+     - CTRL+Tab, CTRL+Shift+Tab     Cycle through windows.
+     - CTRL+Click                   Input text into a Slider or Drag widget.
+   - Extended features with `io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard`:
+     - Tab, SHIFT+Tab:              Cycle through every items.
+     - Arrow keys                   Move through items using directional navigation. Tweak value.
+     - Arrow keys + Alt, Shift      Tweak slower, tweak faster (when using arrow keys).
+     - Enter                        Activate item (prefer text input when possible).
+     - Space                        Activate item (prefer tweaking with arrows when possible).
+     - Escape                       Deactivate item, leave child window, close popup.
+     - Page Up, Page Down           Previous page, next page.
+     - Home, End                    Scroll to top, scroll to bottom.
+     - Alt                          Toggle between scrolling layer and menu layer.
+     - CTRL+Tab then Ctrl+Arrows    Move window. Hold SHIFT to resize instead of moving.
+   - Output when ImGuiConfigFlags_NavEnableKeyboard set,
+     - io.WantCaptureKeyboard flag is set when keyboard is claimed.
+     - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
+     - io.NavVisible: true when the navigation cursor is visible (usually goes to back false when mouse is used).
+
+ - GAMEPAD CONTROLS
+   - Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+   - Particularly useful to use Dear ImGui on a console system (e.g. PlayStation, Switch, Xbox) without a mouse!
+   - Download controller mapping PNG/PSD at http://dearimgui.com/controls_sheets
+   - Backend support: backend needs to:
+      - Set 'io.BackendFlags |= ImGuiBackendFlags_HasGamepad' + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
+      - For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
+        Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
+   - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,
+     with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
+
+ - REMOTE INPUTS SHARING & MOUSE EMULATION
+   - PS4/PS5 users: Consider emulating a mouse cursor with DualShock touch pad or a spare analog stick as a mouse-emulation fallback.
+   - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + run examples/libs/synergy/uSynergy.c (on your console/tablet/phone app)
+     in order to share your PC mouse/keyboard.
+   - See https://github.com/ocornut/imgui/wiki/Useful-Extensions#remoting for other remoting solutions.
+   - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the io.ConfigNavMoveSetMousePos flag.
+     Enabling io.ConfigNavMoveSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs Dear ImGui to move your mouse cursor along with navigation movements.
+     When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
+     When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that.
+     (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!)
+     (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
+     to set a boolean to ignore your other external mouse positions until the external source is moved again.)
+
+
+ PROGRAMMER GUIDE
+ ================
+
+ READ FIRST
+ ----------
+ - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki)
+ - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone!
+   The UI can be highly dynamic, there are no construction or destruction steps, less superfluous
+   data retention on your side, less state duplication, less state synchronization, fewer bugs.
+ - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
+   Or browse https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html for interactive web version.
+ - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
+ - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
+   You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki.
+ - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
+   For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,
+   where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
+ - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
+ - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
+   If you get an assert, read the messages and comments around the assert.
+ - This codebase aims to be highly optimized:
+   - A typical idle frame should never call malloc/free.
+   - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible.
+   - We put particular energy in making sure performances are decent with typical "Debug" build settings as well.
+     Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all.
+ - This codebase aims to be both highly opinionated and highly flexible:
+   - This code works because of the things it choose to solve or not solve.
+   - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers,
+     and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now).
+     This is to increase compatibility, increase maintainability and facilitate use from other languages.
+   - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
+     See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
+     We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally.
+   - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction
+     (so don't use ImVector in your code or at our own risk!).
+   - Building: We don't use nor mandate a build system for the main library.
+     This is in an effort to ensure that it works in the real world aka with any esoteric build setup.
+     This is also because providing a build system for the main library would be of little-value.
+     The build problems are almost never coming from the main library but from specific backends.
+
+
+ HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
+ ----------------------------------------------
+ - Update submodule or copy/overwrite every file.
+ - About imconfig.h:
+   - You may modify your copy of imconfig.h, in this case don't overwrite it.
+   - or you may locally branch to modify imconfig.h and merge/rebase latest.
+   - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
+     specify a custom path for your imconfig.h file and instead not have to modify the default one.
+
+ - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h)
+ - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master".
+ - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.
+ - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
+   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
+   from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
+   likely be a comment about it. Please report any issue to the GitHub page!
+ - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.
+ - Try to keep your copy of Dear ImGui reasonably up to date!
+
+
+ GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
+ ---------------------------------------------------------------
+ - See https://github.com/ocornut/imgui/wiki/Getting-Started.
+ - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
+ - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
+ - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
+   It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL).
+ - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
+ - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
+ - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
+   Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
+   phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render().
+ - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.
+ - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
+
+
+ HOW A SIMPLE APPLICATION MAY LOOK LIKE
+ --------------------------------------
+ EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder).
+ The sub-folders in examples/ contain examples applications following this structure.
+
+     // Application init: create a dear imgui context, setup some options, load fonts
+     ImGui::CreateContext();
+     ImGuiIO& io = ImGui::GetIO();
+     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
+     // TODO: Fill optional fields of the io structure later.
+     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
+
+     // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
+     ImGui_ImplWin32_Init(hwnd);
+     ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
+
+     // Application main loop
+     while (true)
+     {
+         // Feed inputs to dear imgui, start new frame
+         ImGui_ImplDX11_NewFrame();
+         ImGui_ImplWin32_NewFrame();
+         ImGui::NewFrame();
+
+         // Any application code here
+         ImGui::Text("Hello, world!");
+
+         // Render dear imgui into screen
+         ImGui::Render();
+         ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
+         g_pSwapChain->Present(1, 0);
+     }
+
+     // Shutdown
+     ImGui_ImplDX11_Shutdown();
+     ImGui_ImplWin32_Shutdown();
+     ImGui::DestroyContext();
+
+ EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE
+
+     // Application init: create a dear imgui context, setup some options, load fonts
+     ImGui::CreateContext();
+     ImGuiIO& io = ImGui::GetIO();
+     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
+     // TODO: Fill optional fields of the io structure later.
+     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
+
+     // Build and load the texture atlas into a texture
+     // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)
+     int width, height;
+     unsigned char* pixels = nullptr;
+     io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
+
+     // At this point you've got the texture data and you need to upload that to your graphic system:
+     // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
+     // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
+     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
+     io.Fonts->SetTexID((void*)texture);
+
+     // Application main loop
+     while (true)
+     {
+        // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
+        // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform Backends)
+        io.DeltaTime = 1.0f/60.0f;              // set the time elapsed since the previous frame (in seconds)
+        io.DisplaySize.x = 1920.0f;             // set the current display width
+        io.DisplaySize.y = 1280.0f;             // set the current display height here
+        io.AddMousePosEvent(mouse_x, mouse_y);  // update mouse position
+        io.AddMouseButtonEvent(0, mouse_b[0]);  // update mouse button states
+        io.AddMouseButtonEvent(1, mouse_b[1]);  // update mouse button states
+
+        // Call NewFrame(), after this point you can use ImGui::* functions anytime
+        // (So you want to try calling NewFrame() as early as you can in your main loop to be able to use Dear ImGui everywhere)
+        ImGui::NewFrame();
+
+        // Most of your application code here
+        ImGui::Text("Hello, world!");
+        MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
+        MyGameRender(); // may use any Dear ImGui functions as well!
+
+        // Render dear imgui, swap buffers
+        // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
+        ImGui::EndFrame();
+        ImGui::Render();
+        ImDrawData* draw_data = ImGui::GetDrawData();
+        MyImGuiRenderFunction(draw_data);
+        SwapBuffers();
+     }
+
+     // Shutdown
+     ImGui::DestroyContext();
+
+ To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application,
+ you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
+ Please read the FAQ entry "How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?" about this.
+
+
+ HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE
+ ---------------------------------------------
+ The backends in impl_impl_XXX.cpp files contain many working implementations of a rendering function.
+
+    void MyImGuiRenderFunction(ImDrawData* draw_data)
+    {
+       // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
+       // TODO: Setup texture sampling state: sample with bilinear filtering (NOT point/nearest filtering). Use 'io.Fonts->Flags |= ImFontAtlasFlags_NoBakedLines;' to allow point/nearest filtering.
+       // TODO: Setup viewport covering draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
+       // TODO: Setup orthographic projection matrix cover draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
+       // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
+       ImVec2 clip_off = draw_data->DisplayPos;
+       for (int n = 0; n < draw_data->CmdListsCount; n++)

+

+ API BREAKING CHANGES
+ ====================
+
+ Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
+ Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
+ When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
+ You can read releases logs https://github.com/ocornut/imgui/releases for more details.
+
+ - 2024/11/06 (1.91.5) - commented/obsoleted out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before)
+                            - io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022).
+                            - io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022).
+                            - pre-1.87 backends are not supported:
+                               - backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields.
+                               - backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields.
+                            - for more reference:
+                              - read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88.
+                              - read https://github.com/ocornut/imgui/issues/4921
+                            - if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest.
+                       - obsoleted ImGuiKey_COUNT (it is unusually error-prone/misleading since valid keys don't start at 0). probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END?
+                       - fonts: removed const qualifiers from most font functions in prevision for upcoming font improvements.
+ - 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete).
+ - 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool.
+                         moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!).
+                         kept legacy names (will obsolete) + code that copies settings once the first time. Dynamically changing the old value won't work. Switch to using the new value!
+ - 2024/10/10 (1.91.4) - the typedef for ImTextureID now defaults to ImU64 instead of void*. (#1641)
+                         this removes the requirement to redefine it for backends which are e.g. storing descriptor sets or other 64-bits structures when building on 32-bits archs. It therefore simplify various building scripts/helpers.
+                         you may have compile-time issues if you were casting to 'void*' instead of 'ImTextureID' when passing your types to functions taking ImTextureID values, e.g. ImGui::Image().
+                         in doubt it is almost always better to do an intermediate intptr_t cast, since it allows casting any pointer/integer type without warning:
+                            - May warn:    ImGui::Image((void*)MyTextureData, ...);
+                            - May warn:    ImGui::Image((void*)(intptr_t)MyTextureData, ...);
+                            - Won't warn:  ImGui::Image((ImTextureID)(intptr_t)MyTextureData), ...);
+  -                      note that you can always define ImTextureID to be your own high-level structures (with dedicated constructors) if you like.
+ - 2024/10/03 (1.91.3) - drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is a still special value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76)
+                       - drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange. It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed).
+                         although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76)
+ - 2024/09/10 (1.91.2) - internals: using multiple overlayed ButtonBehavior() with same ID will now have io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030)
+                         it was one of the rare case where using same ID is legal. workarounds: (1) use single ButtonBehavior() call with multiple _MouseButton flags, or (2) surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag()
+ - 2024/08/23 (1.91.1) - renamed ImGuiChildFlags_Border to ImGuiChildFlags_Borders for consistency. kept inline redirection flag.
+ - 2024/08/22 (1.91.1) - moved some functions from ImGuiIO to ImGuiPlatformIO structure:
+                            - io.GetClipboardTextFn         -> platform_io.Platform_GetClipboardTextFn + changed 'void* user_data' to 'ImGuiContext* ctx'. Pull your user data from platform_io.ClipboardUserData.
+                            - io.SetClipboardTextFn         -> platform_io.Platform_SetClipboardTextFn + same as above line.
+                            - io.PlatformOpenInShellFn      -> platform_io.Platform_OpenInShellFn (#7660)
+                            - io.PlatformSetImeDataFn       -> platform_io.Platform_SetImeDataFn
+                            - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278)
+                            - access those via GetPlatformIO() instead of GetIO().
+                         some were introduced very recently and often automatically setup by core library and backends, so for those we are exceptionally not maintaining a legacy redirection symbol.
+                       - commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). As a reminder:
+                            - old ImageButton() before 1.89 used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID)
+                            - new ImageButton() since 1.89 requires an explicit 'const char* str_id'
+                            - old ImageButton() before 1.89 had frame_padding' override argument.
+                            - new ImageButton() since 1.89 always use style.FramePadding, which you can freely override with PushStyleVar()/PopStyleVar().
+ - 2024/07/25 (1.91.0) - obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (see #7838 on GitHub for more info)
+                         you should never need those functions. you can do everything with GetCursorScreenPos() and GetContentRegionAvail() in a more simple way.
+                            - instead of:  GetWindowContentRegionMax().x - GetCursorPos().x
+                            - you can use: GetContentRegionAvail().x
+                            - instead of:  GetWindowContentRegionMax().x + GetWindowPos().x
+                            - you can use: GetCursorScreenPos().x + GetContentRegionAvail().x // when called from left edge of window
+                            - instead of:  GetContentRegionMax()
+                            - you can use: GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates
+                            - instead of:  GetWindowContentRegionMax().x - GetWindowContentRegionMin().x
+                            - you can use: GetContentRegionAvail() // when called from left edge of window
+ - 2024/07/15 (1.91.0) - renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups. (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
+                         (internals: also renamed ImGuiItemFlags_SelectableDontClosePopup into ImGuiItemFlags_AutoClosePopups with inverted behaviors)
+ - 2024/07/15 (1.91.0) - obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag(ImGuiItemFlags_ButtonRepeat, ...)/PopItemFlag().
+ - 2024/07/02 (1.91.0) - commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)
+                       - commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)
+                            - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.
+ - 2024/07/02 (1.91.0) - IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness.
+                            - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data);
+                            - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);
+ - 2024/06/21 (1.90.9) - BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for BeginChild() anyhow.
+                            - old: BeginChild("Name", size, 0, ImGuiWindowFlags_NavFlattened);
+                            - new: BeginChild("Name", size, ImGuiChildFlags_NavFlattened, 0);
+ - 2024/06/21 (1.90.9) - io: ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data, newly added ClearInputMouse() does.
+ - 2024/06/20 (1.90.9) - renamed ImGuiDragDropFlags_SourceAutoExpirePayload to ImGuiDragDropFlags_PayloadAutoExpire.
+ - 2024/06/18 (1.90.9) - style: renamed ImGuiCol_TabActive -> ImGuiCol_TabSelected, ImGuiCol_TabUnfocused -> ImGuiCol_TabDimmed, ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected.
+ - 2024/06/10 (1.90.9) - removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to ImGuiStoragePair (simpler for many languages).
+ - 2024/06/06 (1.90.8) - reordered ImGuiInputTextFlags values. This should not be breaking unless you are using generated headers that have values not matching the main library.
+ - 2024/06/06 (1.90.8) - removed 'ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft', was mostly unused and misleading.
+ - 2024/05/27 (1.90.7) - commented out obsolete symbols marked obsolete in 1.88 (May 2022):
+                            - old: CaptureKeyboardFromApp(bool)
+                            - new: SetNextFrameWantCaptureKeyboard(bool)
+                            - old: CaptureMouseFromApp(bool)
+                            - new: SetNextFrameWantCaptureMouse(bool)
+ - 2024/05/22 (1.90.7) - inputs (internals): renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more explicit and reduce confusion with the default it is a non-zero value and cannot be the default value (never made public, but disclosing as I expect a few users caught on owner-aware inputs).
+                       - inputs (internals): renamed ImGuiInputFlags_RouteGlobalLow -> ImGuiInputFlags_RouteGlobal, ImGuiInputFlags_RouteGlobal -> ImGuiInputFlags_RouteGlobalOverFocused, ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobalHighest.
+                       - inputs (internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order in function signatures:
+                            - old: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);
+                            - new: Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);
+                       - inputs (internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked(): swapped last two parameters order in function signatures.
+                            - old: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);
+                            - new: IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);
+                            - old: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0);
+                            - new: IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0);
+                         for various reasons those changes makes sense. They are being made because making some of those API public.
+                         only past users of imgui_internal.h with the extra parameters will be affected. Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL.
+ - 2024/05/16 (1.90.7) - inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent() as this naturally align with how macOS X uses those keys.
+                           - it shouldn't really affect you unless you had custom shortcut swapping in place for macOS X apps.
+                           - removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super. It is now unnecessary to specific cross-platform idiomatic shortcuts. (#2343, #4084, #5923, #456)
+ - 2024/05/14 (1.90.7) - backends: SDL_Renderer2 and SDL_Renderer3 backend now take a SDL_Renderer* in their RenderDrawData() functions.
+ - 2024/04/18 (1.90.6) - TreeNode: Fixed a layout inconsistency when using an empty/hidden label followed by a SameLine() call. (#7505, #282)
+                           - old: TreeNode("##Hidden"); SameLine(); Text("Hello");     // <-- This was actually incorrect! BUT appeared to look ok with the default style where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).
+                           - new: TreeNode("##Hidden"); SameLine(0, 0); Text("Hello"); // <-- This is correct for all styles values.
+                         with the fix, IF you were successfully using TreeNode("")+SameLine(); you will now have extra spacing between your TreeNode and the following item.
+                         You'll need to change the SameLine() call to SameLine(0,0) to remove this extraneous spacing. This seemed like the more sensible fix that's not making things less consistent.
+                         (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).
+ - 2024/03/18 (1.90.5) - merged the radius_x/radius_y parameters in ImDrawList::AddEllipse(), AddEllipseFilled() and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those functions were added in 1.90, we are not adding inline redirection functions. The transition is easy and should affect few users. (#2743, #7417)
+ - 2024/03/08 (1.90.5) - inputs: more formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set. It has been unnecessary and a no-op since 1.87 (it returns the same value as passed when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)
+                           - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)
+ - 2024/01/15 (1.90.2) - commented out obsolete ImGuiIO::ImeWindowHandle marked obsolete in 1.87, favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
+ - 2023/12/19 (1.90.1) - commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter.
+ - 2023/11/06 (1.90.1) - removed CalcListClipping() marked obsolete in 1.86. Prefer using ImGuiListClipper which can return non-contiguous ranges.
+ - 2023/11/05 (1.90.1) - imgui_freetype: commented out ImGuiFreeType::BuildFontAtlas() obsoleted in 1.81. prefer using #define IMGUI_ENABLE_FREETYPE or see commented code for manual calls.
+ - 2023/11/05 (1.90.1) - internals,columns: commented out legacy ImGuiColumnsFlags_XXX symbols redirecting to ImGuiOldColumnsFlags_XXX, obsoleted from imgui_internal.h in 1.80.
+ - 2023/11/09 (1.90.0) - removed IM_OFFSETOF() macro in favor of using offsetof() available in C++11. Kept redirection define (will obsolete).
+ - 2023/11/07 (1.90.0) - removed BeginChildFrame()/EndChildFrame() in favor of using BeginChild() with the ImGuiChildFlags_FrameStyle flag. kept inline redirection function (will obsolete).
+                         those functions were merely PushStyle/PopStyle helpers, the removal isn't so much motivated by needing to add the feature in BeginChild(), but by the necessity to avoid BeginChildFrame() signature mismatching BeginChild() signature and features.
+ - 2023/11/02 (1.90.0) - BeginChild: upgraded 'bool border = true' parameter to 'ImGuiChildFlags flags' type, added ImGuiChildFlags_Border equivalent. As with our prior "bool-to-flags" API updates, the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a smoother transition, meaning all existing calls will still work.
+                           - old: BeginChild("Name", size, true)
+                           - new: BeginChild("Name", size, ImGuiChildFlags_Border)
+                           - old: BeginChild("Name", size, false)
+                           - new: BeginChild("Name", size) or BeginChild("Name", 0) or BeginChild("Name", size, ImGuiChildFlags_None)
+                         **AMEND FROM THE FUTURE: from 1.91.1, 'ImGuiChildFlags_Border' is called 'ImGuiChildFlags_Borders'**
+ - 2023/11/02 (1.90.0) - BeginChild: added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense for BeginChild() anyhow.
+                           - old: BeginChild("Name", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);
+                           - new: BeginChild("Name", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);
+ - 2023/09/27 (1.90.0) - io: removed io.MetricsActiveAllocations introduced in 1.63. Same as 'g.DebugMemAllocCount - g.DebugMemFreeCount' (still displayed in Metrics, unlikely to be accessed by end-user).
+ - 2023/09/26 (1.90.0) - debug tools: Renamed ShowStackToolWindow() ("Stack Tool") to ShowIDStackToolWindow() ("ID Stack Tool"), as earlier name was misleading. Kept inline redirection function. (#4631)
+ - 2023/09/15 (1.90.0) - ListBox, Combo: changed signature of "name getter" callback in old one-liner ListBox()/Combo() apis. kept inline redirection function (will obsolete).
+                           - old: bool Combo(const char* label, int* current_item, bool (*getter)(void* user_data, int idx, const char** out_text), ...)
+                           - new: bool Combo(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
+                           - old: bool ListBox(const char* label, int* current_item, bool (*getting)(void* user_data, int idx, const char** out_text), ...);
+                           - new: bool ListBox(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
+ - 2023/09/08 (1.90.0) - commented out obsolete redirecting functions:
+                           - GetWindowContentRegionWidth()  -> use GetWindowContentRegionMax().x - GetWindowContentRegionMin().x. Consider that generally 'GetContentRegionAvail().x' is more useful.
+                           - ImDrawCornerFlags_XXX          -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details + grep commented names in sources.
+                       - commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for AddRect()/AddRectFilled()/PathRect()/AddImageRounded() -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details
+ - 2023/08/25 (1.89.9) - clipper: Renamed IncludeRangeByIndices() (also called ForceDisplayRangeByIndices() before 1.89.6) to IncludeItemsByIndex(). Kept inline redirection function. Sorry!
+ - 2023/07/12 (1.89.8) - ImDrawData: CmdLists now owned, changed from ImDrawList** to ImVector<ImDrawList*>. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). (#6406, #4879, #1878)
+ - 2023/06/28 (1.89.7) - overlapping items: obsoleted 'SetItemAllowOverlap()' (called after item) in favor of calling 'SetNextItemAllowOverlap()' (called before item). 'SetItemAllowOverlap()' didn't and couldn't work reliably since 1.89 (2022-11-15).
+ - 2023/06/28 (1.89.7) - overlapping items: renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap', 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'. Kept redirecting enums (will obsolete).
+ - 2023/06/28 (1.89.7) - overlapping items: IsItemHovered() now by default return false when querying an item using AllowOverlap mode which is being overlapped. Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior.
+ - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610)
+ - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage.
+ - 2023/05/30 (1.89.6) - backends: renamed "imgui_impl_sdlrenderer.cpp" to "imgui_impl_sdlrenderer2.cpp" and "imgui_impl_sdlrenderer.h" to "imgui_impl_sdlrenderer2.h". This is in prevision for the future release of SDL3.
+ - 2023/05/22 (1.89.6) - listbox: commented out obsolete/redirecting functions that were marked obsolete more than two years ago:
+                           - ListBoxHeader()  -> use BeginListBox() (note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for reference)
+                           - ListBoxFooter()  -> use EndListBox()
+ - 2023/05/15 (1.89.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin().
+ - 2023/05/15 (1.89.6) - clipper: renamed ImGuiListClipper::ForceDisplayRangeByIndices() to ImGuiListClipper::IncludeRangeByIndices().
+ - 2023/03/14 (1.89.4) - commented out redirecting enums/functions names that were marked obsolete two years ago:
+                           - ImGuiSliderFlags_ClampOnInput        -> use ImGuiSliderFlags_AlwaysClamp
+                           - ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite
+                           - ImDrawList::AddBezierCurve()         -> use ImDrawList::AddBezierCubic()
+                           - ImDrawList::PathBezierCurveTo()      -> use ImDrawList::PathBezierCubicCurveTo()
+ - 2023/03/09 (1.89.4) - renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop(). Kept inline redirection functions (will obsolete).
+ - 2023/03/09 (1.89.4) - tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will _currently_ always return true, but further changes down the line may change this, best to clarify API sooner.
+ - 2023/02/15 (1.89.4) - moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h.
+                         Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA,
+                         it has been frequently requested by people to use our own. We had an opt-in define which was
+                         previously fulfilled in imgui_internal.h. It is now fulfilled in imgui.h. (#6164)
+                           - OK:     #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui.h" / #include "imgui_internal.h"
+                           - Error:  #include "imgui.h" / #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui_internal.h"
+ - 2023/02/07 (1.89.3) - backends: renamed "imgui_impl_sdl.cpp" to "imgui_impl_sdl2.cpp" and "imgui_impl_sdl.h" to "imgui_impl_sdl2.h". (#6146) This is in prevision for the future release of SDL3.
+ - 2022/10/26 (1.89)   - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79.
+ - 2022/10/12 (1.89)   - removed runtime patching of invalid "%f"/"%0.f" format strings for DragInt()/SliderInt(). This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details.
+ - 2022/09/26 (1.89)   - renamed and merged keyboard modifiers key enums and flags into a same set. Kept inline redirection enums (will obsolete).
+                           - ImGuiKey_ModCtrl  and ImGuiModFlags_Ctrl  -> ImGuiMod_Ctrl
+                           - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift
+                           - ImGuiKey_ModAlt   and ImGuiModFlags_Alt   -> ImGuiMod_Alt
+                           - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super
+                         the ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends.
+                         the ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api only by third-party extensions.
+                         exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway.
+ - 2022/09/20 (1.89)   - ImGuiKey is now a typed enum, allowing ImGuiKey_XXX symbols to be named in debuggers.
+                         this will require uses of legacy backend-dependent indices to be casted, e.g.
+                            - with imgui_impl_glfw:  IsKeyPressed(GLFW_KEY_A) -> IsKeyPressed((ImGuiKey)GLFW_KEY_A);
+                            - with imgui_impl_win32: IsKeyPressed('A')        -> IsKeyPressed((ImGuiKey)'A')
+                            - etc. However if you are upgrading code you might well use the better, backend-agnostic IsKeyPressed(ImGuiKey_A) now!
+ - 2022/09/12 (1.89) - removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)', always pass a pointer value explicitly. NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr);
+ - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020):
+                         - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.
+                         - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.
+                         - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags)
+ - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries.
+                       this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item.
+                         - previously this would make the window content size ~200x200:
+                              Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End();
+                         - instead, please submit an item:
+                              Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End();
+                         - alternative:
+                              Begin(...) + Dummy(ImVec2(200,200)) + End();
+                         - content size is now only extended when submitting an item!
+                         - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert.
+                         - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it.
+ - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete).
+                        - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter.
+                        - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
+                          - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values.
+                          - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer.
+                        - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
+                          - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier.
+                          - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this.
+ - 2022/07/08 (1.89) - inputs: removed io.NavInputs[] and ImGuiNavInput enum (following 1.87 changes).
+                        - Official backends from 1.87+                  -> no issue.
+                        - Official backends from 1.60 to 1.86           -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating!
+                        - Custom backends not writing to io.NavInputs[] -> no issue.
+                        - Custom backends writing to io.NavInputs[]     -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing!
+                        - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[].
+ - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete).
+ - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary.
+ - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO.
+ - 2022/01/20 (1.87) - inputs: reworded gamepad IO.
+                        - Backend writing to io.NavInputs[]            -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values.
+ - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).
+ - 2022/01/17 (1.87) - inputs: reworked mouse IO.
+                        - Backend writing to io.MousePos               -> backend should call io.AddMousePosEvent()
+                        - Backend writing to io.MouseDown[]            -> backend should call io.AddMouseButtonEvent()
+                        - Backend writing to io.MouseWheel             -> backend should call io.AddMouseWheelEvent()
+                        - Backend writing to io.MouseHoveredViewport   -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only]
+                       note: for all calls to IO new functions, the Dear ImGui context should be bound/current.
+                       read https://github.com/ocornut/imgui/issues/4921 for details.
+ - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unnecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.
+                        - IsKeyPressed(MY_NATIVE_KEY_XXX)              -> use IsKeyPressed(ImGuiKey_XXX)
+                        - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX))      -> use IsKeyPressed(ImGuiKey_XXX)
+                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes).
+                        - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.*
+                     - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
+                     - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
+ - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.
+ - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
+ - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019)
+                        - ImGui::SetNextTreeNodeOpen()        -> use ImGui::SetNextItemOpen()
+                        - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x
+                        - ImGui::TreeAdvanceToLabelPos()      -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());
+                        - ImFontAtlas::CustomRect             -> use ImFontAtlasCustomRect
+                        - ImGuiColorEditFlags_RGB/HSV/HEX     -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex
+ - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings
+ - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function.
+ - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful.
+ - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
+                        - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
+                        - ImFont::GlyphRangesBuilder  -> use ImFontGlyphRangesBuilder
+ - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID().
+                        - if you are using official backends from the source tree: you have nothing to do.
+                        - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().
+ - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags.
+                        - ImDrawCornerFlags_TopLeft  -> use ImDrawFlags_RoundCornersTopLeft
+                        - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight
+                        - ImDrawCornerFlags_None     -> use ImDrawFlags_RoundCornersNone etc.
+                       flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API.
+                       breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners":
+                        - rounding == 0.0f + flags == 0 --> meant no rounding  --> unchanged (common use)
+                        - rounding  > 0.0f + flags != 0 --> meant rounding     --> unchanged (common use)
+                        - rounding == 0.0f + flags != 0 --> meant no rounding  --> unchanged (unlikely use)
+                        - rounding  > 0.0f + flags == 0 --> meant no rounding  --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f.
+                       this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok.
+                       the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts.
+                       legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise).
+ - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):
+                        - ImGui::SetScrollHere()              -> use ImGui::SetScrollHereY()
+ - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing.
+ - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
+ - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file  with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
+ - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
+ - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
+                     - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).
+                     - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete).
+ - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.
+                     - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.
+                     - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.
+ - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018):
+                        - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
+                        - ImGuiCol_ModalWindowDarkening       -> use ImGuiCol_ModalWindowDimBg
+                        - ImGuiInputTextCallback              -> use ImGuiTextEditCallback
+                        - ImGuiInputTextCallbackData          -> use ImGuiTextEditCallbackData
+ - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).
+ - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added!
+ - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.
+ - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures
+ - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/.
+ - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018):
+                        - io.RenderDrawListsFn pointer        -> use ImGui::GetDrawData() value and call the render function of your backend
+                        - ImGui::IsAnyWindowFocused()         -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)
+                        - ImGui::IsAnyWindowHovered()         -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
+                        - ImGuiStyleVar_Count_                -> use ImGuiStyleVar_COUNT
+                        - ImGuiMouseCursor_Count_             -> use ImGuiMouseCursor_COUNT
+                      - removed redirecting functions names that were marked obsolete in 1.61 (May 2018):
+                        - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision.
+                        - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
+ - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).
+ - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).
+ - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
+ - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.
+ - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.
+ - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now!
+ - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().
+                       replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).
+                       worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:
+                       - if you omitted the 'power' parameter (likely!), you are not affected.
+                       - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.
+                       - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.
+                       see https://github.com/ocornut/imgui/issues/3361 for all details.
+                       kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
+                       for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
+                     - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.
+ - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
+ - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]
+ - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
+ - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().
+ - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
+ - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
+ - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
+ - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
+                       - ShowTestWindow()                    -> use ShowDemoWindow()
+                       - IsRootWindowFocused()               -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
+                       - IsRootWindowOrAnyChildFocused()     -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
+                       - SetNextWindowContentWidth(w)        -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
+                       - GetItemsLineHeightWithSpacing()     -> use GetFrameHeightWithSpacing()
+                       - ImGuiCol_ChildWindowBg              -> use ImGuiCol_ChildBg
+                       - ImGuiStyleVar_ChildWindowRounding   -> use ImGuiStyleVar_ChildRounding
+                       - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
+                       - IMGUI_DISABLE_TEST_WINDOWS          -> use IMGUI_DISABLE_DEMO_WINDOWS
+ - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API.
+ - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
+ - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
+ - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
+ - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
+ - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
+                       - Begin() [old 5 args version]        -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
+                       - IsRootWindowOrAnyChildHovered()     -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
+                       - AlignFirstTextHeightToWidgets()     -> use AlignTextToFramePadding()
+                       - SetNextWindowPosCenter()            -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
+                       - ImFont::Glyph                       -> use ImFontGlyph
+ - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
+                       if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
+                       The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
+                       If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
+ - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
+ - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
+ - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
+ - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
+                       overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
+                       This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
+                       Please reach out if you are affected.
+ - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
+ - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
+ - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
+ - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
+ - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
+ - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
+ - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value!
+ - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
+ - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
+ - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
+ - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
+ - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
+ - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
+ - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
+ - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
+                       If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
+ - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
+ - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
+                       NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
+                       Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
+ - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
+ - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
+ - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
+ - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
+ - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
+ - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
+ - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
+ - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.).
+                       old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports.
+                       when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call.
+                       in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
+ - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
+ - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
+ - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
+                       If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
+                       To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
+                       If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
+ - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
+                       consistent with other functions. Kept redirection functions (will obsolete).
+ - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
+ - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch).
+ - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
+ - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
+ - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
+ - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
+ - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
+ - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
+                       - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
+                       - removed Shutdown() function, as DestroyContext() serve this purpose.
+                       - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
+                       - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
+                       - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
+ - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
+ - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
+ - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
+ - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
+ - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
+ - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
+ - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
+ - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
+                     - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
+ - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
+ - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
+ - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
+ - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
+                       Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
+ - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
+ - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
+ - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
+ - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
+ - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
+ - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
+ - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
+                       removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
+                         IsItemHoveredRect()        --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
+                         IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
+                         IsMouseHoveringWindow()    --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
+ - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
+ - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
+ - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
+ - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
+ - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
+ - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
+                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
+                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
+ - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
+ - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
+ - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
+ - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
+ - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
+ - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
+ - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
+ - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
+                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
+                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'
+ - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
+ - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
+ - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
+ - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild().
+ - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
+ - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
+ - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal.
+ - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
+                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
+                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
+                       ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
+                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
+ - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
+ - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
+ - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
+ - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
+ - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337).
+ - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
+ - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
+ - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
+ - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
+ - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
+ - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
+ - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
+                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
+                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
+ - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
+ - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
+ - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
+ - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
+                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
+ - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
+                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
+                     - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
+                     - the signature of the io.RenderDrawListsFn handler has changed!
+                       old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
+                       new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
+                         parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
+                         ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
+                         ImDrawCmd:  'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
+                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
+                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
+                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
+ - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
+ - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
+ - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
+ - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
+ - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry!
+ - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
+ - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
+ - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
+ - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
+ - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
+ - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
+ - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
+ - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
+ - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
+ - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
+ - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
+ - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
+ - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
+ - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
+ - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
+ - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
+ - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
+ - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
+ - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
+ - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
+ - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
+ - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
+                       - old:  const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];
+                       - new:  unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier);
+                       you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.
+ - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID()
+ - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
+ - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
+ - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
+ - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
+ - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
+ - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
+ - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
+ - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
+ - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
+ - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
+ - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
+ - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
+ - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes

+ Q&A: Community
+ ==============
+
+ Q: How can I help?
+ A: - Businesses: please reach out to "omar AT dearimgui DOT com" if you work in a place using Dear ImGui!
+      We can discuss ways for your company to fund development via invoiced technical support, maintenance or sponsoring contacts.
+      This is among the most useful thing you can do for Dear ImGui. With increased funding, we sustain and grow work on this project.
+      >>> See https://github.com/ocornut/imgui/wiki/Funding
+    - Businesses: you can also purchase licenses for the Dear ImGui Automation/Test Engine.
+    - If you are experienced with Dear ImGui and C++, look at the GitHub issues, look at the Wiki, and see how you want to help and can help!
+    - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
+      You may post screenshot or links in the gallery threads. Visuals are ideal as they inspire other programmers.
+      But even without visuals, disclosing your use of dear imgui helps the library grow credibility, and help other teams and programmers with taking decisions.
+    - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on GitHub or privately).

+// DLL users:
+// - Heaps and globals are not shared across DLL boundaries!
+// - You will need to call SetCurrentContext() + SetAllocatorFunctions() for each static/DLL boundary you are calling from.
+// - Same applies for hot-reloading mechanisms that are reliant on reloading DLL (note that many hot-reloading mechanisms work without DLL).
+// - Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
+// - Confused? In a debugger: add GImGui to your watch window and notice how its value changes depending on your current location (which DLL boundary you are in).
+
+// Current context pointer. Implicitly used by all Dear ImGui functions. Always assumed to be != NULL.
+// - ImGui::CreateContext() will automatically set this pointer if it is NULL.
+//   Change to a different context by calling ImGui::SetCurrentContext().
+// - Important: Dear ImGui functions are not thread-safe because of this pointer.
+//   If you want thread-safety to allow N threads to access N different contexts:
+//   - Change this variable to use thread local storage so each thread can refer to a different context, in your imconfig.h:
+//         struct ImGuiContext;
+//         extern thread_local ImGuiContext* MyImGuiTLS;
+//         #define GImGui MyImGuiTLS
+//     And then define MyImGuiTLS in one of your cpp files. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
+//   - Future development aims to make this context pointer explicit to all calls. Also read https://github.com/ocornut/imgui/issues/586
+//   - If you need a finite number of contexts, you may compile and use multiple instances of the ImGui code from a different namespace.
+// - DLL users: read comments above.

+    // - 3. Optionally call TableSetupScrollFreeze() to request scroll freezing of columns/rows.

+// - The DEFAULT sizing policies are:
+//    - Default to ImGuiTableFlags_SizingFixedFit    if ScrollX is on, or if host window has ImGuiWindowFlags_AlwaysAutoResize.
+//    - Default to ImGuiTableFlags_SizingStretchSame if ScrollX is off.
+// - When ScrollX is off:
+//    - Table defaults to ImGuiTableFlags_SizingStretchSame -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch with same weight.
+//    - Columns sizing policy allowed: Stretch (default), Fixed/Auto.
+//    - Fixed Columns (if any) will generally obtain their requested width (unless the table cannot fit them all).
+//    - Stretch Columns will share the remaining width according to their respective weight.
+//    - Mixed Fixed/Stretch columns is possible but has various side-effects on resizing behaviors.
+//      The typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
+//      (this is because the visible order of columns have subtle but necessary effects on how they react to manual resizing).
+// - When ScrollX is on:
+//    - Table defaults to ImGuiTableFlags_SizingFixedFit -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed
+//    - Columns sizing policy allowed: Fixed/Auto mostly.
+//    - Fixed Columns can be enlarged as needed. Table will show a horizontal scrollbar if needed.
+//    - When using auto-resizing (non-resizable) fixed columns, querying the content width to use item right-alignment e.g. SetNextItemWidth(-FLT_MIN) doesn't make sense, would create a feedback loop.
+//    - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
+//      If you specify a value for 'inner_width' then effectively the scrolling space is known and Stretch or mixed Fixed/Stretch columns become meaningful again.

+    //    - Recovery after running an exception handler or any error processing which may skip code after an error has been detected.
+    // - Error recovery is not perfect nor guaranteed! It is a feature to ease development.
+    //   You not are not supposed to rely on it in the course of a normal application run.
+    // - Functions that support error recovery are using IM_ASSERT_USER_ERROR() instead of IM_ASSERT().
+    // - By design, we do NOT allow error recovery to be 100% silent. One of the three options needs to be checked!
+    // - Always ensure that on programmers seats you have at minimum Asserts or Tooltips enabled when making direct imgui API calls!
+    //   Otherwise it would severely hinder your ability to catch and correct mistakes!
+    // Read https://github.com/ocornut/imgui/wiki/Error-Handling for details.
+    // - Programmer seats: keep asserts (default), or disable asserts and keep error tooltips (new and nice!)
+    // - Non-programmer seats: maybe disable asserts, but make sure errors are resurfaced (tooltips, visible log entries, use callback etc.)
+    // - Recovery after error/exception: record stack sizes with ErrorRecoveryStoreState(), disable assert, set log callback (to e.g. trigger high-level breakpoint), recover with ErrorRecoveryTryToRecoverState(), restore settings.

+    bool        ConfigErrorRecoveryEnableTooltip;   // = true       // Enable tooltip on recoverable errors. The tooltip include a way to enable asserts if they were disabled.

+    // Option to enable various debug tools showing buttons that will call the IM_DEBUG_BREAK() macro.
+    // - The Item Picker tool will be available regardless of this being enabled, in order to maximize its discoverability.
+    // - Requires a debugger being attached, otherwise IM_DEBUG_BREAK() options will appear to crash your application.

+// Helper: Manually clip large list of items.

+// The clipper calculates the range of visible items and advance the cursor to compensate for the non-visible items we have skipped.
+// (Dear ImGui already clip items based on their bounds but: it needs to first layout the item to do so, and generally
+//  fetching/submitting your own data incurs additional cost. Coarse clipping using ImGuiListClipper allows you to easily

+//       for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)
+//           ImGui::Text("line number %d", i);
+// Generally what happens is:
+// - Clipper lets you process the first element (DisplayStart = 0, DisplayEnd = 1) regardless of it being visible or not.
+// - User code submit that one element.
+// - Clipper can measure the height of the first element
+// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.

+//-----------------------------------------------------------------------------
+
+// Multi-selection system
+// Documentation at: https://github.com/ocornut/imgui/wiki/Multi-Select
+// - Refer to 'Demo->Widgets->Selection State & Multi-Select' for demos using this.
+// - This system implements standard multi-selection idioms (CTRL+Mouse/Keyboard, SHIFT+Mouse/Keyboard, etc)
+//   with support for clipper (skipping non-visible items), box-select and many other details.
+// - Selectable(), Checkbox() are supported but custom widgets may use it as well.
+// - TreeNode() is technically supported but... using this correctly is more complicated: you need some sort of linear/random access to your tree,
+//   which is suited to advanced trees setups also implementing filters and clipper. We will work toward simplifying and demoing it.
+// - In the spirit of Dear ImGui design, your code owns actual selection data.
+//   This is designed to allow all kinds of selection storage you may use in your application e.g. set/map/hash.
+// About ImGuiSelectionBasicStorage:
+// - This is an optional helper to store a selection state and apply selection requests.
+// - It is used by our demos and provided as a convenience to quickly implement multi-selection.
+// Usage:
+// - Identify submitted items with SetNextItemSelectionUserData(), most likely using an index into your current data-set.
+// - Store and maintain actual selection data using persistent object identifiers.
+// - Usage flow:
+//     BEGIN - (1) Call BeginMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (2) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 6.
+//           - (3) [If using clipper] You need to make sure RangeSrcItem is always submitted. Calculate its index and pass to clipper.IncludeItemByIndex(). If storing indices in ImGuiSelectionUserData, a simple clipper.IncludeItemByIndex(ms_io->RangeSrcItem) call will work.
+//     LOOP  - (4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.
+//     END   - (5) Call EndMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (6) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 2.
+//     If you submit all items (no clipper), Step 2 and 3 are optional and will be handled by each item themselves. It is fine to always honor those steps.
+// About ImGuiSelectionUserData:
+// - This can store an application-defined identifier (e.g. index or pointer) submitted via SetNextItemSelectionUserData().
+// - In return we store them into RangeSrcItem/RangeFirstItem/RangeLastItem and other fields in ImGuiMultiSelectIO.
+// - Most applications will store an object INDEX, hence the chosen name and type. Storing an index is natural, because
+//   SetRange requests will give you two end-points and you will need to iterate/interpolate between them to update your selection.
+// - However it is perfectly possible to store a POINTER or another IDENTIFIER inside ImGuiSelectionUserData.
+//   Our system never assume that you identify items by indices, it never attempts to interpolate between two values.
+// - If you enable ImGuiMultiSelectFlags_NoRangeSelect then it is guaranteed that you will never have to interpolate
+//   between two ImGuiSelectionUserData, which may be a convenient way to use part of the feature with less code work.
+// - As most users will want to store an index, for convenience and to reduce confusion we use ImS64 instead of void*,
+//   being syntactically easier to downcast. Feel free to reinterpret_cast and store a pointer inside.

+//  - Mouse cursor shapes for software cursor rendering (unless setting 'Flags |= ImFontAtlasFlags_NoMouseCursors' in the font atlas).
+// It is the user-code responsibility to setup/build the atlas, then upload the pixel data into a texture accessible by your graphics api.
+//  - Optionally, call any of the AddFont*** functions. If you don't call any, the default font embedded in the code will be loaded for you.
+//  - Call GetTexDataAsAlpha8() or GetTexDataAsRGBA32() to build and retrieve pixels data.
+//  - Upload the pixels data into a texture within your graphics system (see imgui_impl_xxxx.cpp examples)
+//  - Call SetTexID(my_tex_id); and pass the pointer/identifier to your texture in a format natural to your graphics API.
+//    This value will be passed back to you during rendering to identify the texture. Read FAQ entry about ImTextureID for more details.
+// Common pitfalls:
+// - If you pass a 'glyph_ranges' array to AddFont*** functions, you need to make sure that your array persist up until the
+//   atlas is build (when calling GetTexData*** or Build()). We only copy the pointer, not the data.
+// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
+//   You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
+// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
+// - This is an old API and it is currently awkward for those and various other reasons! We will address them in the future!

+// Typical tables call flow: (root level is generally public API):
+//-----------------------------------------------------------------------------
+// - BeginTable()                               user begin into a table
+//    | BeginChild()                            - (if ScrollX/ScrollY is set)
+//    | TableBeginInitMemory()                  - first time table is used

+//    | TableBeginApplyRequests()               - apply queued resizing/reordering/hiding requests
+//    | - TableSetColumnWidth()                 - apply resizing width (for mouse resize, often requested by previous frame)
+//    |    - TableUpdateColumnsWeightFromWidth()- recompute columns weights (of stretch columns) from their respective width
+// - TableSetupColumn()                         user submit columns details (optional)

+//-----------------------------------------------------------------------------
+// - TableUpdateLayout() [Internal]             followup to BeginTable(): setup everything: widths, columns positions, clipping rectangles. Automatically called by the FIRST call to TableNextRow() or TableHeadersRow().
+//    | TableSetupDrawChannels()                - setup ImDrawList channels
+//    | TableUpdateBorders()                    - detect hovering columns for resize, ahead of contents submission
+//    | TableBeginContextMenuPopup()
+//    | - TableDrawDefaultContextMenu()         - draw right-click context menu contents
+//-----------------------------------------------------------------------------
+// - TableHeadersRow() or TableHeader()         user submit a headers row (optional)
+//    | TableSortSpecsClickColumn()             - when left-clicked: alter sort order and sort direction
+//    | TableOpenContextMenu()                  - when right-clicked: trigger opening of the default context menu
+// - TableGetSortSpecs()                        user queries updated sort specs (optional, generally after submitting headers)
+// - TableNextRow()                             user begin into a new row (also automatically called by TableHeadersRow())
+//    | TableEndRow()                           - finish existing row
+//    | TableBeginRow()                         - add a new row
+// - TableSetColumnIndex() / TableNextColumn()  user begin into a cell
+//    | TableEndCell()                          - close existing column/cell
+//    | TableBeginCell()                        - enter into current column/cell
+// - [...]                                      user emit contents
+//-----------------------------------------------------------------------------
+// - EndTable()                                 user ends the table

+// TABLE SIZING
+//-----------------------------------------------------------------------------
+// (Read carefully because this is subtle but it does make sense!)
+//-----------------------------------------------------------------------------
+// About 'outer_size':
+// Its meaning needs to differ slightly depending on if we are using ScrollX/ScrollY flags.
+// Default value is ImVec2(0.0f, 0.0f).
+//   X
+//   - outer_size.x <= 0.0f  ->  Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge.
+//   - outer_size.x  > 0.0f  ->  Set Fixed width.
+//   Y with ScrollX/ScrollY disabled: we output table directly in current window
+//   - outer_size.y  < 0.0f  ->  Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful if parent window can vertically scroll.
+//   - outer_size.y  = 0.0f  ->  No minimum height (but will auto extend, unless _NoHostExtendY is set)
+//   - outer_size.y  > 0.0f  ->  Set Minimum height (but will auto extend, unless _NoHostExtendY is set)
+//   Y with ScrollX/ScrollY enabled: using a child window for scrolling
+//   - outer_size.y  < 0.0f  ->  Bottom-align. Not meaningful if parent window can vertically scroll.
+//   - outer_size.y  = 0.0f  ->  Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window.
+//   - outer_size.y  > 0.0f  ->  Set Exact height. Recommended when using Scrolling on any axis.
+//-----------------------------------------------------------------------------
+// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.
+// Important to note how the two flags have slightly different behaviors!
+//   - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used.
+//   - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible.
+// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height.
+// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not useful and not easily noticeable).
+//-----------------------------------------------------------------------------
+// About 'inner_width':
+//   With ScrollX disabled:
+//   - inner_width          ->  *ignored*
+//   With ScrollX enabled:
+//   - inner_width  < 0.0f  ->  *illegal* fit in known width (right align from outer_size.x) <-- weird
+//   - inner_width  = 0.0f  ->  fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns.
+//   - inner_width  > 0.0f  ->  override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space!
+//-----------------------------------------------------------------------------
+// Details:
+// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept
+//   of "available space" doesn't make sense.
+// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding
+//   of what the value does.
+//-----------------------------------------------------------------------------
+
+//-----------------------------------------------------------------------------
+// COLUMNS SIZING POLICIES
+// (Reference: ImGuiTableFlags_SizingXXX flags and ImGuiTableColumnFlags_WidthXXX flags)
+//-----------------------------------------------------------------------------
+// About overriding column sizing policy and width/weight with TableSetupColumn():
+// We use a default parameter of -1 for 'init_width'/'init_weight'.
+//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  <= 0 (default)  --> width is automatic
+//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  >  0 (explicit) --> width is custom
+//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight <= 0 (default)  --> weight is 1.0f
+//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight >  0 (explicit) --> weight is custom
+// Widths are specified _without_ CellPadding. If you specify a width of 100.0f, the column will be cover (100.0f + Padding * 2.0f)
+// and you can fit a 100.0f wide item in it without clipping and with padding honored.
+//-----------------------------------------------------------------------------
+// About default sizing policy (if you don't specify a ImGuiTableColumnFlags_WidthXXXX flag)
+//   - with Table policy ImGuiTableFlags_SizingFixedFit      --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is equal to contents width
+//   - with Table policy ImGuiTableFlags_SizingFixedSame     --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is max of all contents width
+//   - with Table policy ImGuiTableFlags_SizingStretchSame   --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is 1.0f
+//   - with Table policy ImGuiTableFlags_SizingStretchWeight --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is proportional to contents
+// Default Width and default Weight can be overridden when calling TableSetupColumn().
+//-----------------------------------------------------------------------------
+// About mixing Fixed/Auto and Stretch columns together:
+//   - the typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
+//   - using mixed policies with ScrollX does not make much sense, as using Stretch columns with ScrollX does not make much sense in the first place!
+//     that is, unless 'inner_width' is passed to BeginTable() to explicitly provide a total width to layout columns in.
+//   - when using ImGuiTableFlags_SizingFixedSame with mixed columns, only the Fixed/Auto columns will match their widths to the width of the maximum contents.
+//   - when using ImGuiTableFlags_SizingStretchSame with mixed columns, only the Stretch columns will match their weights/widths.
+//-----------------------------------------------------------------------------
+// About using column width:
+// If a column is manually resizable or has a width specified with TableSetupColumn():
+//   - you may use GetContentRegionAvail().x to query the width available in a given column.
+//   - right-side alignment features such as SetNextItemWidth(-x) or PushItemWidth(-x) will rely on this width.
+// If the column is not resizable and has no width specified with TableSetupColumn():
+//   - its width will be automatic and be set to the max of items submitted.
+//   - therefore you generally cannot have ALL items of the columns use e.g. SetNextItemWidth(-FLT_MIN).
+//   - but if the column has one or more items of known/fixed size, this will become the reference width used by SetNextItemWidth(-FLT_MIN).
+//-----------------------------------------------------------------------------
+
+
+//-----------------------------------------------------------------------------
+// TABLES CLIPPING/CULLING
+//-----------------------------------------------------------------------------
+// About clipping/culling of Rows in Tables:
+// - For large numbers of rows, it is recommended you use ImGuiListClipper to submit only visible rows.
+//   ImGuiListClipper is reliant on the fact that rows are of equal height.
+//   See 'Demo->Tables->Vertical Scrolling' or 'Demo->Tables->Advanced' for a demo of using the clipper.
+// - Note that auto-resizing columns don't play well with using the clipper.
+//   By default a table with _ScrollX but without _Resizable will have column auto-resize.
+//   So, if you want to use the clipper, make sure to either enable _Resizable, either setup columns width explicitly with _WidthFixed.
+//-----------------------------------------------------------------------------
+// About clipping/culling of Columns in Tables:
+// - Both TableSetColumnIndex() and TableNextColumn() return true when the column is visible or performing
+//   width measurements. Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know
+//   it is not going to contribute to row height.
+//   In many situations, you may skip submitting contents for every column but one (e.g. the first one).
+// - Case A: column is not hidden by user, and at least partially in sight (most common case).
+// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output.
+// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.).
+//
+//                        [A]         [B]          [C]
+//  TableNextColumn():    true        false        false       -> [userland] when TableNextColumn() / TableSetColumnIndex() returns false, user can skip submitting items but only if the column doesn't contribute to row height.
+//          SkipItems:    false       false        true        -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output.

+// This function reorder draw channels based on matching clip rectangle, to facilitate merging them. Called by EndTable().
+// For simplicity we call it TableMergeDrawChannels() but in fact it only reorder channels + overwrite ClipRect,
+// actual merging is done by table->DrawSplitter.Merge() which is called right after TableMergeDrawChannels().
+//
+// Columns where the contents didn't stray off their local clip rectangle can be merged. To achieve
+// this we merge their clip rect and make them contiguous in the channel list, so they can be merged
+// by the call to DrawSplitter.Merge() following to the call to this function.
+// We reorder draw commands by arranging them into a maximum of 4 distinct groups:
+//
+//   1 group:               2 groups:              2 groups:              4 groups:
+//   [ 0. ] no freeze       [ 0. ] row freeze      [ 01 ] col freeze      [ 01 ] row+col freeze
+//   [ .. ]  or no scroll   [ 2. ]  and v-scroll   [ .. ]  and h-scroll   [ 23 ]  and v+h-scroll
+//
+// Each column itself can use 1 channel (row freeze disabled) or 2 channels (row freeze enabled).
+// When the contents of a column didn't stray off its limit, we move its channels into the corresponding group
+// based on its position (within frozen rows/columns groups or not).
+// At the end of the operation our 1-4 groups will each have a ImDrawCmd using the same ClipRect.
+// This function assume that each column are pointing to a distinct draw channel,
+// otherwise merge_group->ChannelsCount will not match set bit count of merge_group->ChannelsMask.
+//
+// Column channels will not be merged into one of the 1-4 groups in the following cases:
+// - The contents stray off its clipping rectangle (we only compare the MaxX value, not the MinX value).
+//   Direct ImDrawList calls won't be taken into account by default, if you use them make sure the ImGui:: bounds
+//   matches, by e.g. calling SetCursorScreenPos().
+// - The channel uses more than one draw command itself. We drop all our attempt at merging stuff here..
+//   we could do better but it's going to be rare and probably not worth the hassle.
+// Columns for which the draw channel(s) haven't been merged with other will use their own ImDrawCmd.
+//
+// This function is particularly tricky to understand.. take a breath.

+// The ButtonBehavior() function is key to many interactions and used by many/most widgets.
+// Because we handle so many cases (keyboard/gamepad navigation, drag and drop) and many specific behavior (via ImGuiButtonFlags_),
+// this code is a little complex.
+// By far the most common path is interacting with the Mouse using the default ImGuiButtonFlags_PressedOnClickRelease button behavior.
+// See the series of events below and the corresponding state reported by dear imgui:

+// 
+// stb_rect_pack.h - v1.01 - public domain - rectangle packing
+// Sean Barrett 2014
+//
+// Useful for e.g. packing rectangular textures into an atlas.
+// Does not do rotation.
+//
+// Before #including,
+//
+//    #define STB_RECT_PACK_IMPLEMENTATION
+//
+// in the file that you want to have the implementation.
+//
+// Not necessarily the awesomest packing method, but better than
+// the totally naive one in stb_truetype (which is primarily what
+// this is meant to replace).
+//
+// Has only had a few tests run, may have issues.
+//
+// More docs to come.
+//
+// No memory allocations; uses qsort() and assert() from stdlib.
+// Can override those by defining STBRP_SORT and STBRP_ASSERT.
+//
+// This library currently uses the Skyline Bottom-Left algorithm.
+//
+// Please note: better rectangle packers are welcome! Please
+// implement them to the same API, but with a different init
+// function.

+// [DEAR IMGUI]
+// This is a slightly modified version of stb_textedit.h 1.14.
+// Those changes would need to be pushed into nothings/stb:
+// - Fix in stb_textedit_discard_redo (see https://github.com/nothings/stb/issues/321)
+// - Fix in stb_textedit_find_charpos to handle last line (see https://github.com/ocornut/imgui/issues/6000 + #6783)
+// - Added name to struct or it may be forward declared in our code.
+// - Added UTF-8 support (see https://github.com/nothings/stb/issues/188 + https://github.com/ocornut/imgui/pull/7925)
+// Grep for [DEAR IMGUI] to find the changes.
+// - Also renamed macros used or defined outside of IMSTB_TEXTEDIT_IMPLEMENTATION block from STB_TEXTEDIT_* to IMSTB_TEXTEDIT_*
+
+// stb_textedit.h - v1.14  - public domain - Sean Barrett
+// Development of this library was sponsored by RAD Game Tools
+//
+// This C header file implements the guts of a multi-line text-editing
+// widget; you implement display, word-wrapping, and low-level string
+// insertion/deletion, and stb_textedit will map user inputs into
+// insertions & deletions, plus updates to the cursor position,
+// selection state, and undo state.
+//
+// It is intended for use in games and other systems that need to build
+// their own custom widgets and which do not have heavy text-editing
+// requirements (this library is not recommended for use for editing large
+// texts, as its performance does not scale and it has limited undo).
+//
+// Non-trivial behaviors are modelled after Windows text controls.
+//
+//
+// LICENSE
+//
+// See end of file for license information.
+//
+//
+// DEPENDENCIES
+//
+// Uses the C runtime function 'memmove', which you can override
+// by defining IMSTB_TEXTEDIT_memmove before the implementation.
+// Uses no other functions. Performs no runtime allocations.

+//
+// USAGE
+//
+// This file behaves differently depending on what symbols you define
+// before including it.
+//
+//
+// Header-file mode:
+//
+//   If you do not define STB_TEXTEDIT_IMPLEMENTATION before including this,
+//   it will operate in "header file" mode. In this mode, it declares a
+//   single public symbol, STB_TexteditState, which encapsulates the current
+//   state of a text widget (except for the string, which you will store
+//   separately).
+//
+//   To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
+//   primitive type that defines a single character (e.g. char, wchar_t, etc).
+//
+//   To save space or increase undo-ability, you can optionally define the
+//   following things that are used by the undo system:
+//
+//      STB_TEXTEDIT_POSITIONTYPE         small int type encoding a valid cursor position
+//      STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
+//      STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
+//
+//   If you don't define these, they are set to permissive types and
+//   moderate sizes. The undo system does no memory allocations, so
+//   it grows STB_TexteditState by the worst-case storage which is (in bytes):
+//
+//        [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT
+//      +          sizeof(STB_TEXTEDIT_CHARTYPE)      * STB_TEXTEDIT_UNDOCHARCOUNT
+//
+//
+// Implementation mode:
+//
+//   If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
+//   will compile the implementation of the text edit widget, depending
+//   on a large number of symbols which must be defined before the include.
+//
+//   The implementation is defined only as static functions. You will then
+//   need to provide your own APIs in the same file which will access the
+//   static functions.
+//
+//   The basic concept is that you provide a "string" object which
+//   behaves like an array of characters. stb_textedit uses indices to
+//   refer to positions in the string, implicitly representing positions
+//   in the displayed textedit. This is true for both plain text and
+//   rich text; even with rich text stb_truetype interacts with your
+//   code as if there was an array of all the displayed characters.
+//
+// Symbols that must be the same in header-file and implementation mode:
+//
+//     STB_TEXTEDIT_CHARTYPE             the character type
+//     STB_TEXTEDIT_POSITIONTYPE         small type that is a valid cursor position
+//     STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
+//     STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
+//
+// Symbols you must define for implementation mode:
+//
+//    STB_TEXTEDIT_STRING               the type of object representing a string being edited,
+//                                      typically this is a wrapper object with other data you need
+//
+//    STB_TEXTEDIT_STRINGLEN(obj)       the length of the string (ideally O(1))
+//    STB_TEXTEDIT_LAYOUTROW(&r,obj,n)  returns the results of laying out a line of characters
+//                                        starting from character #n (see discussion below)
+//    STB_TEXTEDIT_GETWIDTH(obj,n,i)    returns the pixel delta from the xpos of the i'th character
+//                                        to the xpos of the i+1'th char for a line of characters
+//                                        starting at character #n (i.e. accounts for kerning
+//                                        with previous char)
+//    STB_TEXTEDIT_KEYTOTEXT(k)         maps a keyboard input to an insertable character
+//                                        (return type is int, -1 means not valid to insert)
+//    STB_TEXTEDIT_GETCHAR(obj,i)       returns the i'th character of obj, 0-based
+//    STB_TEXTEDIT_NEWLINE              the character returned by _GETCHAR() we recognize
+//                                        as manually wordwrapping for end-of-line positioning
+//
+//    STB_TEXTEDIT_DELETECHARS(obj,i,n)      delete n characters starting at i
+//    STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n)   insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
+//
+//    STB_TEXTEDIT_K_SHIFT       a power of two that is or'd in to a keyboard input to represent the shift key
+//
+//    STB_TEXTEDIT_K_LEFT        keyboard input to move cursor left
+//    STB_TEXTEDIT_K_RIGHT       keyboard input to move cursor right
+//    STB_TEXTEDIT_K_UP          keyboard input to move cursor up
+//    STB_TEXTEDIT_K_DOWN        keyboard input to move cursor down
+//    STB_TEXTEDIT_K_PGUP        keyboard input to move cursor up a page
+//    STB_TEXTEDIT_K_PGDOWN      keyboard input to move cursor down a page
+//    STB_TEXTEDIT_K_LINESTART   keyboard input to move cursor to start of line  // e.g. HOME
+//    STB_TEXTEDIT_K_LINEEND     keyboard input to move cursor to end of line    // e.g. END
+//    STB_TEXTEDIT_K_TEXTSTART   keyboard input to move cursor to start of text  // e.g. ctrl-HOME
+//    STB_TEXTEDIT_K_TEXTEND     keyboard input to move cursor to end of text    // e.g. ctrl-END
+//    STB_TEXTEDIT_K_DELETE      keyboard input to delete selection or character under cursor
+//    STB_TEXTEDIT_K_BACKSPACE   keyboard input to delete selection or character left of cursor
+//    STB_TEXTEDIT_K_UNDO        keyboard input to perform undo
+//    STB_TEXTEDIT_K_REDO        keyboard input to perform redo
+//
+// Optional:
+//    STB_TEXTEDIT_K_INSERT              keyboard input to toggle insert mode
+//    STB_TEXTEDIT_IS_SPACE(ch)          true if character is whitespace (e.g. 'isspace'),
+//                                          required for default WORDLEFT/WORDRIGHT handlers
+//    STB_TEXTEDIT_MOVEWORDLEFT(obj,i)   custom handler for WORDLEFT, returns index to move cursor to
+//    STB_TEXTEDIT_MOVEWORDRIGHT(obj,i)  custom handler for WORDRIGHT, returns index to move cursor to
+//    STB_TEXTEDIT_K_WORDLEFT            keyboard input to move cursor left one word // e.g. ctrl-LEFT
+//    STB_TEXTEDIT_K_WORDRIGHT           keyboard input to move cursor right one word // e.g. ctrl-RIGHT
+//    STB_TEXTEDIT_K_LINESTART2          secondary keyboard input to move cursor to start of line
+//    STB_TEXTEDIT_K_LINEEND2            secondary keyboard input to move cursor to end of line
+//    STB_TEXTEDIT_K_TEXTSTART2          secondary keyboard input to move cursor to start of text
+//    STB_TEXTEDIT_K_TEXTEND2            secondary keyboard input to move cursor to end of text
+//
+// Keyboard input must be encoded as a single integer value; e.g. a character code
+// and some bitflags that represent shift states. to simplify the interface, SHIFT must
+// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
+// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
+//
+// You can encode other things, such as CONTROL or ALT, in additional bits, and
+// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
+// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
+// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
+// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
+// API below. The control keys will only match WM_KEYDOWN events because of the
+// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
+// bit so it only decodes WM_CHAR events.
+//
+// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
+// row of characters assuming they start on the i'th character--the width and
+// the height and the number of characters consumed. This allows this library
+// to traverse the entire layout incrementally. You need to compute word-wrapping
+// here.
+//
+// Each textfield keeps its own insert mode state, which is not how normal
+// applications work. To keep an app-wide insert mode, update/copy the
+// "insert_mode" field of STB_TexteditState before/after calling API functions.

+//      key:
+//          call this for keyboard inputs sent to the textfield. you can use it
+//          for "key down" events or for "translated" key events. if you need to
+//          do both (as in Win32), or distinguish Unicode characters from control
+//          inputs, set a high bit to distinguish the two; then you can define the
+//          various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
+//          set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
+//          clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to
+//          anything other type you want before including.
+//          if the STB_TEXTEDIT_KEYTOTEXT function is defined, selected keys are
+//          transformed into text and stb_textedit_text() is automatically called.
+//
+//      text: [DEAR IMGUI] added 2024-09
+//          call this to text inputs sent to the textfield.
+//
+//
+//   When rendering, you can read the cursor position and selection state from
+//   the STB_TexteditState.
+//
+//
+// Notes:
+//
+// This is designed to be usable in IMGUI, so it allows for the possibility of
+// running in an IMGUI that has NOT cached the multi-line layout. For this
+// reason, it provides an interface that is compatible with computing the
+// layout incrementally--we try to make sure we make as few passes through
+// as possible. (For example, to locate the mouse pointer in the text, we
+// could define functions that return the X and Y positions of characters
+// and binary search Y and then X, but if we're doing dynamic layout this
+// will run the layout algorithm many times, so instead we manually search
+// forward in one pass. Similar logic applies to e.g. up-arrow and
+// down-arrow movement.)
+//
+// If it's run in a widget that *has* cached the layout, then this is less
+// efficient, but it's not horrible on modern computers. But you wouldn't
+// want to edit million-line files with it.

+//   Starting with version 1.06, the rasterizer was replaced with a new,
+//   faster and generally-more-precise rasterizer. The new rasterizer more
+//   accurately measures pixel coverage for anti-aliasing, except in the case
+//   where multiple shapes overlap, in which case it overestimates the AA pixel
+//   coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
+//   this turns out to be a problem, you can re-enable the old rasterizer with
+//        #define STBTT_RASTERIZER_VERSION 1
+//   which will incur about a 15% speed hit.
+//
+// ADDITIONAL DOCUMENTATION
+//
+//   Immediately after this block comment are a series of sample programs.
+//
+//   After the sample programs is the "header file" section. This section
+//   includes documentation for each API function.
+//
+//   Some important concepts to understand to use this library:
+//
+//      Codepoint
+//         Characters are defined by unicode codepoints, e.g. 65 is
+//         uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
+//         the hiragana for "ma".
+//
+//      Glyph
+//         A visual character shape (every codepoint is rendered as
+//         some glyph)
+//
+//      Glyph index
+//         A font-specific integer ID representing a glyph
+//
+//      Baseline
+//         Glyph shapes are defined relative to a baseline, which is the
+//         bottom of uppercase characters. Characters extend both above
+//         and below the baseline.
+//
+//      Current Point
+//         As you draw text to the screen, you keep track of a "current point"
+//         which is the origin of each character. The current point's vertical
+//         position is the baseline. Even "baked fonts" use this model.
+//
+//      Vertical Font Metrics
+//         The vertical qualities of the font, used to vertically position
+//         and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+//      Font Size in Pixels or Points
+//         The preferred interface for specifying font sizes in stb_truetype
+//         is to specify how tall the font's vertical extent should be in pixels.
+//         If that sounds good enough, skip the next paragraph.
+//
+//         Most font APIs instead use "points", which are a common typographic
+//         measurement for describing font size, defined as 72 points per inch.
+//         stb_truetype provides a point API for compatibility. However, true
+//         "per inch" conventions don't make much sense on computer displays
+//         since different monitors have different number of pixels per
+//         inch. For example, Windows traditionally uses a convention that
+//         there are 96 pixels per inch, thus making 'inch' measurements have
+//         nothing to do with inches, and thus effectively defining a point to
+//         be 1.333 pixels. Additionally, the TrueType font data provides
+//         an explicit scale factor to scale a given font's glyphs to points,
+//         but the author has observed that this scale factor is often wrong
+//         for non-commercial fonts, thus making fonts scaled in points
+//         according to the TrueType spec incoherently sized in practice.
+//
+// DETAILED USAGE:
+//
+//  Scale:
+//    Select how high you want the font to be, in points or pixels.
+//    Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
+//    a scale factor SF that will be used by all other functions.
+//
+//  Baseline:
+//    You need to select a y-coordinate that is the baseline of where
+//    your text will appear. Call GetFontBoundingBox to get the baseline-relative
+//    bounding box for all characters. SF*-y0 will be the distance in pixels
+//    that the worst-case character could extend above the baseline, so if
+//    you want the top edge of characters to appear at the top of the
+//    screen where y=0, then you would set the baseline to SF*-y0.
+//
+//  Current point:
+//    Set the current point where the first character will appear. The
+//    first character could extend left of the current point; this is font
+//    dependent. You can either choose a current point that is the leftmost
+//    point and hope, or add some padding, or check the bounding box or
+//    left-side-bearing of the first character to be displayed and set
+//    the current point based on that.
+//
+//  Displaying a character:
+//    Compute the bounding box of the character. It will contain signed values
+//    relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
+//    then the character should be displayed in the rectangle from
+//    <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
+//
+//  Advancing for the next character:
+//    Call GlyphHMetrics, and compute 'current_point += SF * advance'.
+//
+//
+// ADVANCED USAGE
+//
+//   Quality:
+//
+//    - Use the functions with Subpixel at the end to allow your characters
+//      to have subpixel positioning. Since the font is anti-aliased, not
+//      hinted, this is very import for quality. (This is not possible with
+//      baked fonts.)
+//
+//    - Kerning is now supported, and if you're supporting subpixel rendering
+//      then kerning is worth using to give your text a polished look.
+//
+//   Performance:
+//
+//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+//      if you don't do this, stb_truetype is forced to do the conversion on
+//      every call.
+//
+//    - There are a lot of memory allocations. We should modify it to take
+//      a temp buffer and allocate from the temp buffer (without freeing),
+//      should help performance a lot.
+//
+// NOTES
+//
+//   The system uses the raw data found in the .ttf file without changing it
+//   and without building auxiliary data structures. This is a bit inefficient
+//   on little-endian systems (the data is big-endian), but assuming you're
+//   caching the bitmaps or glyph shapes this shouldn't be a big deal.
+//
+//   It appears to be very hard to programmatically determine what font a
+//   given file is in a general way. I provide an API for this, but I don't
+//   recommend it.
+//
+//
+// PERFORMANCE MEASUREMENTS FOR 1.06:
+//
+//                      32-bit     64-bit
+//   Previous release:  8.83 s     7.68 s
+//   Pool allocations:  7.72 s     6.34 s
+//   Inline sort     :  6.54 s     5.65 s

+//      choice of variables maps a range from 5 pixels outside the shape to
+//      2 pixels inside the shape to 0..255; this is intended primarily for apply
+//      outside effects only (the interior range is needed to allow proper
+//      antialiasing of the font at *smaller* sizes)
+//
+// The function computes the SDF analytically at each SDF pixel, not by e.g.
+// building a higher-res bitmap and approximating it. In theory the quality
+// should be as high as possible for an SDF of this size & representation, but
+// unclear if this is true in practice (perhaps building a higher-res bitmap

+// vtable, then MinHook the IDirect3DDevice9::Present slot in the host
+// process's vtable so every frame routes through us first." See:
+// - https://github.com/rdbo/D3D9-Hook (reference implementation)
+// - swfoc_lua_bridge/lua_bridge.cpp (sibling project, same MinHook usage)

+// Phase 1 deliberately does NOT render anything. The Present detour just
+// pumps a frame counter and forwards. Phase 2 drops in ImGui.

+//
+// Phase 3's interactive widgets (Spawn / Make-Invuln / Kill, iter 512) must
+// issue bridge calls WITHOUT blocking the D3D9 Present detour. BridgeProbe
+// (hud_state.cpp) does blocking named-pipe I/O — CreateFile + WriteFile +
+// ReadFile. Calling it straight from a button's onClick handler would run
+// that I/O on the render thread; a slow or stalled bridge would then freeze
+// the host game's frame loop. The overlay deliberately avoided exactly this
+// class of hazard in Phase 1 (it polls F1 from a worker thread, never the
+// host's window message pump).
+//
+// ActionQueue keeps that guarantee. The render thread only ever ENQUEUES a
+// request and READS the latest result snapshot — both are short lock-guarded
+// in-memory operations. A single background worker drains the queue and
+// performs the actual (blocking) pipe I/O off the render thread.
+//
+// The send-function is injected (BridgeSendFn) so the queue logic is fully
+// unit-testable with a fake send — no bridge, no game, no DLL. See
+// overlay_action_queue_test.cpp (build_action_queue_test.bat).
+//
+// NOTE: this header is not yet #included by any DLL translation unit. The
+// next overlay iter wires the Phase 3 button onClick handlers to Enqueue()
+// and starts the drain worker — see knowledge-base/overlay_phase3_*_iter513.md.

+// swfoc_overlay/overlay_action_worker.cpp — Phase 3 action-worker lifecycle.
+//
+// overlay_action_worker.h ships two pure, unit-tested pieces: the ActionQueue
+// type (overlay_action_queue.h) and RunActionWorkerLoop(), the drain loop a
+// background thread runs. This file is the DLL-side glue that the header-only
+// unit test deliberately cannot exercise — it spawns the real thread, binds
+// the real blocking bridge send, and owns the one process-wide queue:
+//
+//   ActionQueueInstance() — the single ActionQueue. The render thread enqueues
+//       onto it (Phase 3 button onClick, next overlay iter) and reads
+//       LatestResult() once per frame; the worker thread drains it.
+//   StartActionWorker()   — spawn the background std::thread running
+//       RunActionWorkerLoop() with the real BridgeProbe send (hud_state.h),
+//       a sliced Sleep, and an std::atomic<bool> stop signal. Idempotent.
+//   StopActionWorker()    — set the stop signal and join the thread.
+//       Idempotent.
+//
+// Install() calls StartActionWorker() after StartHudWorker(); Uninstall()
+// calls StopActionWorker() before the D3D9 hooks come down, so an in-flight
+// bridge round-trip drains cleanly. The shape mirrors hud_state.cpp's
+// StartHudWorker / StopHudWorker exactly: idempotent joinable() guard, sliced
+// Sleep so a shutdown requested mid-pause is honoured within one slice.
+//
+// Why a worker thread at all: BridgeProbe does blocking named-pipe I/O. The
+// Phase 3 buttons must never run it on the render thread (inside the D3D9
+// Present detour) or a slow bridge would freeze the host game's frame loop.

+// swfoc_overlay/overlay_action_worker.h — Phase 3 action-worker drain loop.
+//
+// Phase 3's interactive widgets enqueue bridge calls into the ActionQueue
+// (overlay_action_queue.h). Something must DRAIN that queue off the render
+// thread — the render thread runs inside the D3D9 Present detour and must
+// never block on the bridge's named-pipe I/O. That something is a single
+// background worker thread whose body is RunActionWorkerLoop().
+//
+// The loop body is a pure, dependency-free function — no <windows.h>, no
+// <thread>, no bridge. The two ingredients a real worker needs but a test
+// cannot supply (a blocking bridge send, a real Sleep) and the one ingredient
+// the test must control (the shutdown signal) are all INJECTED as callables.
+// That keeps the loop's two subtle behaviours unit-testable with a plain g++:
+//
+//   1. CHECK-FIRST — shouldStop() is consulted BEFORE the first Drain(), so a
+//      worker asked to stop before it ever ticks issues zero bridge I/O. A
+//      drain-then-check (do/while) loop would fire one last bridge call into a
+//      possibly-dead pipe during DLL teardown.
+//   2. NO-SLEEP-ON-STOP — after a drain the loop re-checks shouldStop() before
+//      sleeping, so a shutdown requested mid-tick is honoured immediately
+//      instead of after a full sleep interval.
+//
+// See overlay_action_worker_test.cpp (build_action_worker_test.bat) for the
+// red-green pins on both behaviours.
+//
+// The DLL-side lifecycle that drives this loop lives in
+// overlay_action_worker.cpp (added iter 516): ActionQueueInstance() exposes the
+// one process-wide ActionQueue, and StartActionWorker() / StopActionWorker()
+// spawn / join the single background std::thread that runs RunActionWorkerLoop
+// with the real BridgeProbe send (hud_state.h), a sliced Sleep, and the
+// shutdown atomic. overlay.cpp's Install() / Uninstall() own that lifecycle.
+// Phase 3's RenderActionsWindow wires the buttons to ActionQueueInstance()
+// next overlay iter. See knowledge-base/overlay_phase3_actionworker_iter515.md
+// (the loop) + knowledge-base/overlay_phase3_actionworker_lifecycle_iter516.md

+//                    bridge call into a possibly-dead pipe during DLL

+//                    was never called — they pass ONLY on the while-form.
+//   - NO-SLEEP-ON-STOP : a loop that sleeps unconditionally before re-checking
+//                    shutdown would delay DLL teardown by a full sleep
+//                    interval. The "PIN no-sleep-on-stop" check stops the loop

+// swfoc_overlay/overlay_actions.h — Phase 3 bridge-command builders.
+//
+// The overlay's Phase 3 "Actions" widgets (Spawn / Make-Invuln / Kill /
+// Teleport / Faction-Switch) issue engine mutations by sending a single Lua
+// line through the existing bridge pipe (\\.\pipe\swfoc_bridge, see
+// hud_state.cpp::BridgeProbe). The bridge runs that line via DoString.
+//
+// The SWFOC_*Lua write wires take their arguments as **Lua expression
+// strings** — each argument is a Lua string literal whose CONTENTS are
+// themselves a Lua expression. That means two levels of quoting:
+//
+//   inner expression : Find_Player("REBEL")
+//   as a Lua literal : "Find_Player(\"REBEL\")"
+//
+// Getting that escaping wrong silently breaks the call (the bridge sees a
+// truncated or malformed expression). These builders are pure, deterministic
+// functions so the escaping can be pinned by overlay_actions_test.cpp before
+// the render path ever depends on it.
+//
+// Verified wire signatures (swfoc_lua_bridge/lua_bridge.cpp, 2026-05-21):
+//   SWFOC_SpawnUnitLua(player_expr, type_expr, position_expr)  -> Spawn_Unit
+//   SWFOC_MakeUnitInvulnLua(unit_lua_expr, bool_lua_expr)      -> :Make_Invulnerable
+//   SWFOC_KillUnit(obj_addr)                                   -> hull = 0
+//   SWFOC_TeleportUnitLua(unit_lua_expr, position_lua_expr)    -> :Teleport
+//   SWFOC_ChangeUnitOwner(unit_lua_expr, player_lua_expr)      -> :Change_Owner
+//   SWFOC_HealUnitLua(unit_lua_expr)                           -> :Heal
+//
+// NOTE: the overlay-interactive spec referred to the invuln wire as
+// "SWFOC_MakeInvulnerableLua" — that name does not exist. The real

+// =============================================================================
+// swfoc_overlay/overlay_camera_bookmarks.h — Phase 6 camera-bookmark kernel.
+//
+// Phase 6 (iter 304-307) expands the overlay's hotkey surface into power-user
+// features. iter-304 (spec line 62) is the "top quick win" the agent #2 UX
+// research flagged: BOOKMARKABLE CAMERA POSITIONS bound to F6 / F7 / F8.
+//
+//   - SAVE  : press (e.g.) Shift+F6 -> the overlay reads the engine-current
+//             camera position via the SWFOC_GetCameraPos LIVE wire (iter-237)
+//             and stores it in bookmark slot 0.
+//   - RECALL: press F6 -> the overlay jumps the camera back to the stored
+//             viewpoint via the SWFOC_SetCameraPos LIVE wire (iter-237).
+//
+// Both wires already exist and are LIVE — iter-304 ships NO new bridge wire.
+// This header is the pure kernel: a 3-slot bookmark store, the wire-result
+// parser that turns SWFOC_GetCameraPos's "x,y,z" string into a stored
+// position, and the recall ActionRequest builder. The overlay.cpp glue
+// (deferred, build-only verifiable — exactly like every Phase 5 kernel iter)
+// only polls the F-keys and hands BuildRecall()'s ActionRequest to the
+// iter-513 ActionQueue; the deciding logic is here so a unit test pins it
+// before the input path depends on it.
+//
+// WIRE FACTS (swfoc_lua_bridge/lua_bridge.cpp, re-read 2026-05-21)
+// ---------------------------------------------------------------
+//   SWFOC_SetCameraPos(x, y, z)  -> 3 plain Lua NUMBER args. Unlike the
+//       SWFOC_*Lua write wires there is NO nested-expression quoting — the
+//       bridge reads the args with fn_tonumber. (registered lua_bridge.cpp
+//       :8244; Lua_SetCameraPos :3893)
+//   SWFOC_GetCameraPos()         -> no args; returns the engine-current
+//       camera position as a 3-decimal "x.xxx,y.yyy,z.zzz" string. When no
+//       tactical camera is active it returns the literal "0.000,0.000,0.000"
+//       (NOT an ERR: string). (registered :8245; Lua_GetCameraPos :6011)
+//
+// ParseCameraPos cannot tell "camera genuinely at the origin" from "no
+// active camera" — both wire-read as "0.000,0.000,0.000". That is the
+// bridge's ambiguity, not the kernel's: a bookmark saved as (0,0,0) is a
+// valid bookmark at the origin. The deferred render glue may choose to warn
+// when it saves an exact-origin bookmark; the kernel stays honest and stores
+// what the wire gave it.
+//
+// RED-GREEN REGRESSION PINS (overlay_camera_bookmarks_test.cpp)
+// ------------------------------------------------------------
+//   - SAVE THEN RECALL ROUND-TRIPS : Save(slot, p) then BuildRecall(slot)
+//                                    emits SWFOC_SetCameraPos(p) — a store
+//                                    that drops the position fails.
+//   - EMPTY SLOT YIELDS EMPTY LUA  : BuildRecall on an UNSET slot yields an
+//                                    empty `lua` + an "empty" label — an old
+//                                    form that fires SetCameraPos(0,0,0) for
+//                                    an unset key is an accidental camera
+//                                    jump and fails.
+//   - PARSE REJECTS MALFORMED WIRE : ParseCameraPos rejects anything that is
+//                                    not exactly three numeric fields — a
+//                                    partial-parse old form fails.
+//   - MALFORMED WIRE DOESN'T CLOBBER: SaveFromWire with a bad wire string
+//                                    leaves an already-good slot untouched —
+//                                    an old form that wipes the slot fails.
+//   - SLOTS ARE INDEPENDENT        : the three slots store distinct
+//                                    positions — a single-shared-slot old
+//                                    form fails.
+//   - HOTKEY LABELS THE F-KEY      : the recall label names F6 / F7 / F8 for
+//                                    slots 0 / 1 / 2.
+//   - PLAIN NUMBER ARGS            : BuildSetCameraPosCommand emits bare
+//                                    number literals — a copy-from-SWFOC_*Lua
+//                                    old form that LuaQuotes the coords fails.
+//
+// THREADING: CameraBookmarks is touched ONLY by the render / input thread —
+// Save() / SaveFromWire() at the hotkey site, BuildRecall() / Get() while
+// drawing the toolbar. The background action worker drains the ActionQueue
+// but never touches this store. Render-thread-confined, so — like
+// overlay_recent_actions.h's RecentActions — it needs no mutex.
+//
+// Pure, header-only, std-only. Reuses FormatCoord from overlay_actions.h and
+// ActionRequest from overlay_action_queue.h — no new type, no ImGui, no
+// Windows, no bridge. Unit-tested with a plain g++
+// (build_camera_bookmarks_test.bat).

+// =============================================================================
+// swfoc_overlay/overlay_camera_bookmarks_test.cpp — unit test for
+// overlay_camera_bookmarks.h (Phase 6 kickoff, iter 544 / spec iter-304).
+//
+// iter-304 is the Phase 6 "top quick win": bookmarkable camera positions bound
+// to F6 / F7 / F8. overlay_camera_bookmarks.h holds the pure kernel — a 3-slot
+// store, the SWFOC_GetCameraPos wire-result parser, and the recall
+// ActionRequest builder. This test pins all of it so the deferred overlay.cpp
+// F-key glue can depend on it build-only.
+//
+// The integration section runs the full operator cycle: a SWFOC_GetCameraPos
+// wire string -> SaveFromWire -> BuildRecall -> a dispatch-ready ActionRequest
+// whose Lua is a real SWFOC_SetCameraPos bridge call.
+//
+// overlay_camera_bookmarks.h is header-only and std-only (<cerrno> / <cmath> /
+// <cstddef> / <cstdlib> / <string>, plus <cstdio> via overlay_actions.h and
+// <deque> / <functional> / <mutex> via overlay_action_queue.h — -pthread is
+// load-bearing for the threading runtime that include chain pulls in). No
+// game, no pipe, no ImGui. Build + run via build_camera_bookmarks_test.bat.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - SAVE THEN RECALL ROUND-TRIPS  : Save(slot, p) then BuildRecall(slot)
+//                                     emits SWFOC_SetCameraPos(p).
+//   - EMPTY SLOT YIELDS EMPTY LUA   : BuildRecall on an unset slot yields an
+//                                     empty `lua` + an "empty" label.
+//   - PARSE REJECTS MALFORMED WIRE  : ParseCameraPos rejects anything not
+//                                     exactly three numeric fields.
+//   - MALFORMED WIRE DOESN'T CLOBBER: SaveFromWire with a bad string leaves
+//                                     an already-good slot untouched.
+//   - SLOTS ARE INDEPENDENT         : the three slots store distinct values.
+//   - HOTKEY LABELS THE F-KEY       : the recall label names F6 / F7 / F8.
+//   - PLAIN NUMBER ARGS             : BuildSetCameraPosCommand emits bare
+//                                     number literals — never LuaQuoted.

+// swfoc_overlay/overlay_cursor_ray.h — Phase 5 cursor -> world-space kernel.
+//
+// Phase 5 (iter 297-303) makes the overlay click-aware: the operator clicks an
+// in-game unit and an inspector panel opens. iter-297 (the Phase 5 kickoff RE
+// pass) pinned the engine's global D3D transform matrices at 3-tool consensus
+// — see knowledge-base/overlay_phase5_projection_matrix_2026-05-21.md:
+//
+//   0xA6EEE4  global VIEW matrix        (D3DXMATRIX, 64 B)
+//   0xA6EF24  global PROJECTION matrix  (D3DXMATRIX, 64 B)
+//   0xA6F49C  cached VIEW*PROJECTION    (D3DXMATRIX, 64 B)
+//
+// iter-298 (spec line 56) is the PLUMBING iter: turn a cursor pixel into a
+// world-space pick ray. There is no UI yet — iter-299 raycasts unit AABBs
+// against the ray, iter-300 draws the inspector panel. This header is that
+// pure kernel: the math that has a right and a wrong answer and so must be
+// pinned by a unit test before any glue depends on it.
+//
+//   1. ScreenToNdc()  — fold a screen pixel into D3D normalized device
+//      coordinates. Screen Y grows DOWN, NDC Y grows UP — the flip is the
+//      classic off-by-a-mirror bug, so it gets its own pin.
+//   2. Mat4Inverse()  — a true general 4x4 inverse. The unprojection runs the
+//      cursor backwards through the inverse of the view-projection matrix; a
+//      wrong cofactor sign would bend every pick.
+//   3. CursorRay()    — the headline: cursor + viewport + view-projection
+//      matrix -> world-space pick ray (origin on the near plane, unit
+//      direction toward the far plane). It unprojects the near (z_ndc=0) and
+//      far (z_ndc=1) D3D-depth clip points and joins them.
+//   4. RayPlaneZ0()   — intersect the pick ray with the z=0 ground plane.
+//      This is the Phase 4/5 "2D Z=0 plane interim" (spec line 32 / 72): a
+//      cursor pick and a Phase 4 drag-drop drop both resolve onto the same
+//      ground plane, so they share one world coordinate system.
+//
+// RED-GREEN REGRESSION PINS (overlay_cursor_ray_test.cpp)
+// ------------------------------------------------------
+//   - UNPROJECT ROUND-TRIPS : project a known world point through a real
+//                             RH view-projection, feed the screen pixel to
+//                             CursorRay — the world point must lie back on
+//                             the returned ray. A transposed transform or a
+//                             column-major inverse misses by tens of units.
+//   - NDC Y IS FLIPPED      : ScreenToNdc(top-left) is (-1, +1), not
+//                             (-1, -1). Dropping the flip mirrors every pick.
+//   - INVERSE IS A TRUE INVERSE : M * Mat4Inverse(M) == identity. A wrong
+//                             cofactor sign fails this round trip.
+//   - SINGULAR MATRIX REJECTED  : Mat4Inverse of a rank-deficient matrix
+//                             returns false; CursorRay with an un-invertible
+//                             view-projection returns valid=false, never NaN.
+//   - GROUND PICK ON Z=0    : RayPlaneZ0 resolves the world (X, Y) the pick
+//                             ray crosses the ground plane at — the same
+//                             plane Phase 4 drag-drop spawning uses.
+//   - PARALLEL RAY NO HIT   : a ray parallel to the ground reports no hit and
+//                             never divides by a zero direction.z.
+//
+// HONEST DEFER (overlay-interactive.md line 76): cursor-hit-UNIT detection
+// still has no exposed engine wire. iter-298 only produces the world RAY;
+// iter-299 walks per-unit AABBs against it (Mitigation A — client-side
+// raycast). This header deliberately stops at the ray + ground-plane pick.
+//
+// Pure, header-only, std-only (<cmath> for sqrt/tan/fabs) — no ImGui, no
+// Windows, no bridge. Unit-tested with a plain g++ (build_cursor_ray_test.bat).

+// =============================================================================
+// swfoc_overlay/overlay_cursor_ray_test.cpp — unit test for
+// overlay_cursor_ray.h (Phase 5 cont., iter 537 / spec iter-298).
+//
+// iter-298 is the Phase 5 PLUMBING iter: turn a cursor pixel into a world-space
+// pick ray. overlay_cursor_ray.h holds the pure math — Vec3/Mat4 primitives, a
+// general 4x4 inverse, the screen->NDC fold, the cursor->ray unprojection, and
+// the z=0 ground-plane intersection. This test pins all of it so the iter-299
+// AABB raycast and the iter-300 inspector glue can depend on it build-only.
+//
+// The headline test is a ROUND TRIP: build a real right-handed view-projection
+// matrix (D3DXMatrixLookAtRH * D3DXMatrixPerspectiveFovRH, the engine's own
+// render path), project a known world point to a screen pixel, then feed that
+// pixel back through CursorRay — the world point must land back on the ray. A
+// transposed transform, a column-major inverse, or a dropped NDC-Y flip all
+// miss the round trip by tens of world units.
+//
+// overlay_cursor_ray.h is header-only and std-only (<cmath>). Build + run via
+// build_cursor_ray_test.bat — no game, no pipe, no ImGui.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - UNPROJECT ROUND-TRIPS : a world point projected to a pixel and fed back
+//                             through CursorRay must lie on the returned ray.
+//   - NDC Y IS FLIPPED      : ScreenToNdc(top-left) is (-1, +1), not (-1, -1).
+//   - INVERSE IS A TRUE INVERSE : M * Mat4Inverse(M) == identity.
+//   - SINGULAR MATRIX REJECTED  : Mat4Inverse of a rank-deficient matrix
+//                             returns false; CursorRay with such a matrix
+//                             returns valid=false.
+//   - GROUND PICK ON Z=0    : RayPlaneZ0 resolves the world (X, Y) the pick
+//                             ray crosses z=0 at — back to the projected point.
+//   - PARALLEL RAY NO HIT   : a ray parallel to the ground reports no hit.

+//
+// Phase 4 (iter 292-296) lets the operator DRAG a unit-type from the overlay's
+// "Unit type" combo and DROP it on a fixed square spawn pad; the drop point is
+// mapped to a world position and the unit is spawned there via the existing
+// SWFOC_SpawnUnitLua wire (overlay_actions.h::BuildSpawnUnitCommand).
+//
+// This header is the PURE kernel of that feature — the two pieces that have a
+// right and a wrong answer and so must be pinned by a unit test before the
+// ImGui render glue depends on them:
+//
+//   1. PackUnitTypePayload() — copy the dragged unit-type name into the fixed
+//      ImGui drag payload buffer without ever truncating it silently. A
+//      truncated unit name sent to Find_Object_Type would spawn the wrong unit
+//      (or nothing); the pack must fail loudly instead.
+//   2. DropPadToWorld()      — map a pad-local drop pixel to a world (X, Y, 0)
+//      coordinate. An off-by-one in the normalize, or a flipped Y axis, would
+//      spawn units in the wrong place; the test pins center/edges/clamping.
+//
+// HONEST DEFER (overlay-interactive.md): the projection-matrix RVA is NOT
+// pinned, so the overlay cannot map a true 3D screen ray to the world. Phase 4
+// therefore uses a 2D interim — the spawn pad is a flat top-down tactical grid
+// on the Z=0 ground plane. iter-293's minimap and iter-297's projection-matrix
+// RE pass refine this; until then DropPadToWorld is a deliberate coarse map.
+//

+// =============================================================================
+// swfoc_overlay/overlay_faction_switch.h — Phase 6 faction-switch hotkey kernel.
+//
+// Phase 6 (iter 304-307) expands the overlay's hotkey surface into power-user
+// features. iter-305 (spec line 63) is the F3 FACTION-SWITCH HOTKEY: one press
+// re-owns the local player's whole visible army to the next faction in the
+// REBEL -> EMPIRE -> UNDERWORLD -> REBEL cycle.
+//
+// Because flipping an entire army mid-battle is irreversible, iter-305's
+// headline requirement is a CONFIRM-PROMPT — "no accidental mass-defection"
+// (spec line 63). F3 only ARMS a pending switch; a second, deliberate confirm
+// control commits it. This header is the pure kernel of both halves:
+//
+//   1. FactionSwitchPrompt    — the Idle/Armed confirm state machine. Arm()
+//                               on F3, Confirm() / Cancel() on the operator's
+//                               decision.
+//   2. BuildFactionSwitchBatch() — turns the visible-unit set into one
+//                               SWFOC_ChangeUnitOwner ActionRequest per
+//                               affected unit.
+//   3. CountUnitsOwnedBy()    — sizes the confirm prompt; pinned equal to the
+//                               batch size so the prompt never lies.
+//
+// The overlay.cpp glue (deferred, build-only verifiable — exactly like every
+// Phase 5/6 kernel iter) polls F3, draws the prompt, and on confirm hands each
+// batch ActionRequest to the iter-513 ActionQueue. The deciding logic is here
+// so a unit test pins it before the input path depends on it.
+//
+// WIRE FACTS (swfoc_lua_bridge/lua_bridge.cpp, via overlay_actions.h)
+// ------------------------------------------------------------------
+//   SWFOC_ChangeUnitOwner(unit_lua_expr, player_lua_expr) -> :Change_Owner
+//       iter-108 LIVE. Two Lua-expression-string args. The batch reuses
+//       overlay_actions.h::BuildChangeUnitOwnerCommand, so the two-level
+//       quoting is already pinned by overlay_actions_test.cpp.
+//
+// EXACT-UNIT TARGETING — THE HONEST LIMITATION (honest-defer #2)
+// -------------------------------------------------------------
+// SWFOC_ChangeUnitOwner is an engine-METHOD wire: it takes a unit Lua
+// *expression*, not an address, and SWFOC exposes no "object from address"
+// engine-Lua function. So the batch resolves each unit through
+// overlay_inspector_actions.h::InspectorUnitLuaExpr — Find_First_Object(
+// "<type>") — the SAME honest-defer #2 seam the Phase 5 inspector uses.
+//
+// CONSEQUENCE: when several visible units share a type, every per-unit request
+// for that type resolves to the engine's FIRST instance of it. Today a bulk
+// faction switch therefore flips one representative per affected type, not
+// literally every unit. The batch is still built ONE-PER-UNIT (spec line 63:
+// "per unit") so the moment an address->handle resolution wire lands,
+// InspectorUnitLuaExpr changes in one place and the bulk switch becomes a
+// genuine whole-army defection with ZERO kernel change here.
+//
+// RED-GREEN REGRESSION PINS (overlay_faction_switch_test.cpp)
+// ----------------------------------------------------------
+//   - ARM REQUIRES UNITS       : Arm(slot, 0) is refused — an empty confirm
+//                                prompt is meaningless; an old form that
+//                                armed with nothing to switch fails.
+//   - DOUBLE-TAP DOESN'T SKIP  : Arm while already Armed is a no-op — a
+//                                second F3 must not advance the cycle again
+//                                before the operator confirms.
+//   - CONFIRM GATES THE BATCH  : Confirm() returns false unless Armed; the
+//                                batch is dispatched only on a true Confirm.
+//   - CANCEL ABORTS THE SWITCH : after Cancel() a Confirm() returns false —
+//                                an old form where cancel left it armed fails.
+//   - BATCH SKIPS NON-OWNED    : BuildFactionSwitchBatch re-owns ONLY units
+//                                owned by fromSlot — an enemy unit is not
+//                                yours to defect; an old form flipping every
+//                                visible unit fails.
+//   - BATCH RE-OWNS TO NEXT    : each request re-owns to the NEXT faction —
+//                                an old form re-owning to the current faction
+//                                is a no-op and fails.
+//   - COUNT MATCHES BATCH SIZE : CountUnitsOwnedBy(units, fromSlot) equals
+//                                BuildFactionSwitchBatch(...).size() — the
+//                                confirm prompt never lies about how many
+//                                units the commit will dispatch.
+//   - EXPR ESCAPES TYPE NAME   : a unit type carrying a quote is escaped in
+//                                the Find_First_Object literal (inherited
+//                                from InspectorUnitLuaExpr).
+//
+// THREADING: FactionSwitchPrompt is touched ONLY by the render / input thread
+// — Arm() at the F3 site, Confirm()/Cancel() at the prompt controls, the
+// getters while drawing. The background action worker drains the ActionQueue
+// but never touches this state. Render-thread-confined, so — like
+// overlay_camera_bookmarks.h's CameraBookmarks — it needs no mutex.
+//
+// Pure, header-only, std-only (<cstddef>, <string>, <vector>, plus the
+// include chain). No ImGui, no Windows, no bridge. Unit-tested with a plain
+// g++ (build_faction_switch_test.bat).

+// swfoc_overlay/overlay_faction_switch_test.cpp — unit test for
+// overlay_faction_switch.h (Phase 6 cont., iter 545 / spec iter-305).
+//
+// iter-305 is the F3 faction-switch hotkey: one press re-owns the local
+// player's whole visible army to the next faction, gated by a confirm-prompt
+// so a mass-defection can never happen by accident. overlay_faction_switch.h
+// holds the pure kernel — the Idle/Armed confirm state machine, the bulk
+// SWFOC_ChangeUnitOwner batch builder, and the prompt-sizing count. This test
+// pins all of it so the deferred overlay.cpp F3 glue can depend on it
+// build-only.
+//
+// The integration section runs the full operator cycle: a visible-unit set ->
+// CountUnitsOwnedBy -> FactionSwitchPrompt.Arm -> Confirm ->
+// BuildFactionSwitchBatch -> a list of dispatch-ready ActionRequests whose Lua
+// are real SWFOC_ChangeUnitOwner bridge calls.
+//
+// overlay_faction_switch.h is header-only and std-only (<cstddef> / <string> /
+// <vector>, plus <cstdio> via overlay_actions.h and <deque> / <functional> /
+// <mutex> via overlay_action_queue.h — -pthread is load-bearing for the
+// threading runtime that include chain pulls in). No game, no pipe, no ImGui.
+// Build + run via build_faction_switch_test.bat.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - ARM REQUIRES UNITS       : Arm(slot, 0) is refused.
+//   - DOUBLE-TAP DOESN'T SKIP  : Arm while Armed is a no-op.
+//   - CONFIRM GATES THE BATCH  : Confirm() returns false unless Armed.
+//   - CANCEL ABORTS THE SWITCH : after Cancel() a Confirm() returns false.
+//   - BATCH SKIPS NON-OWNED    : only units owned by fromSlot are re-owned.
+//   - BATCH RE-OWNS TO NEXT    : each request re-owns to the NEXT faction.
+//   - COUNT MATCHES BATCH SIZE : CountUnitsOwnedBy == batch size.
+//   - EXPR ESCAPES TYPE NAME   : a quote in a unit type is escaped.

+// swfoc_overlay/overlay_hit_test.h — Phase 5 cursor-hit-unit detection kernel.
+//
+// Phase 5 (iter 297-303) makes the overlay click-aware. iter-297 pinned the
+// engine's D3D transform matrices; iter-298 (overlay_cursor_ray.h) turns a
+// cursor pixel into a world-space pick ray. iter-299 (spec line 57) is the next
+// link: given that pick ray and the visible unit set, find which unit — if any
+// — the operator clicked.
+//
+// SWFOC exposes no "unit under the cursor" engine wire. Rather than pin a new
+// bridge RVA, Phase 5 takes Mitigation A — the CLIENT-SIDE RAYCAST: the HUD
+// worker already enumerates the visible unit set (SWFOC_EnumerateUnits, LIVE
+// iter-104; SWFOC_FindAllObjectsOfType per type, LIVE iter-179), and iter-302
+// appends a per-unit world AABB (min/max vec3) to HudSnapshot. This kernel
+// walks that AABB list and intersects each box with the pick ray entirely in
+// C++ — no new bridge wire, no engine call on the click path.
+//
+// This header is the pure decision kernel — the math that has a right and a
+// wrong answer and so must be pinned by a unit test before the iter-300
+// inspector glue depends on it:
+//
+//   1. AabbIsValid()        — reject an inverted / malformed box before it can
+//      produce a phantom hit.
+//   2. RayAabbIntersect()   — the slab method: intersect a WorldRay with one
+//      axis-aligned box, reporting the entry-face ray parameter. Only
+//      crossings AHEAD of the ray origin (t >= 0) count — a box behind the
+//      camera is never a hit.
+//   3. NearestUnitHit()     — walk the visible-unit AABB list and return the
+//      box the ray enters FIRST (smallest t). This is what "the unit under
+//      the cursor" means when two units overlap in screen space.
+//   4. PickUnitAtCursor()   — the iter-300 convenience seam: cursor pixel +
+//      viewport + view-projection + unit list -> nearest hit unit. Composes
+//      CursorRay (iter-298) and NearestUnitHit.
+//
+// The raycast budget is kMaxRaycastUnits (64) — the same cap iter-302 applies
+// when it appends the AABB set to HudSnapshot. NearestUnitHit clamps to it
+// defensively so a malformed count cannot walk past the snapshot's array.
+//
+// RED-GREEN REGRESSION PINS (overlay_hit_test_test.cpp)
+// ----------------------------------------------------
+//   - NEAREST HIT WINS        : with two boxes on the ray, NearestUnitHit
+//                               returns the one the ray ENTERS first, even
+//                               when the array lists the far box first. A
+//                               "return the first hit found" old form fails.
+//   - MISS REPORTS NO HIT     : a ray passing beside every box returns
+//                               hit=false, index=-1, handle=0 — never a
+//                               phantom unit.
+//   - BOX BEHIND ORIGIN IGNORED : a box entirely behind the ray origin is not
+//                               a hit; the entry parameter must be t >= 0.
+//   - PARALLEL-AXIS RAY HANDLED : a ray parallel to one slab axis hits when it
+//                               lies within the other slabs and misses when
+//                               outside — and never divides by a zero
+//                               direction component.
+//   - INVALID AABB SKIPPED    : an inverted box (min > max) produces no hit;
+//                               AabbIsValid screens it out of the walk.
+//   - ORIGIN INSIDE BOX HITS  : a ray whose origin sits inside a box hits it
+//                               at t = 0 rather than reporting a miss.
+//
+// Pure, header-only, std-only (<cmath> via overlay_cursor_ray.h, plus <cstdint>

+// =============================================================================
+// swfoc_overlay/overlay_hit_test_test.cpp — unit test for overlay_hit_test.h
+// (Phase 5 cont., iter 538 / spec iter-299).
+//
+// iter-299 is the cursor-hit-unit detection link of Phase 5: given the pick ray
+// iter-298 builds and the visible-unit AABB set iter-302 appends to
+// HudSnapshot, decide which unit the operator clicked. overlay_hit_test.h holds
+// the pure math — an AABB validity screen, a slab ray-vs-box intersector, the
+// nearest-hit walk, and the iter-300 PickUnitAtCursor convenience seam. This
+// test pins all of it so the iter-300 inspector glue can depend on it
+// build-only.
+//
+// The integration section runs the exact click pipeline iter-300 will run:
+// build a real right-handed view-projection (the engine's own render path),
+// place unit AABBs on the ground, project a unit's center to a screen pixel,
+// and confirm PickUnitAtCursor recovers that unit — and that a click on empty
+// ground recovers nothing.
+//
+// overlay_hit_test.h is header-only and std-only (<cmath>/<cstdint>/<limits>).
+// Build + run via build_hit_test_test.bat — no game, no pipe, no ImGui.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - NEAREST HIT WINS         : with two boxes on the ray, the one entered
+//                                first is returned even when listed second.
+//   - MISS REPORTS NO HIT      : a ray beside every box -> hit=false,
+//                                index=-1, handle=0.
+//   - BOX BEHIND ORIGIN IGNORED: a box entirely behind the origin is no hit.
+//   - PARALLEL-AXIS RAY HANDLED: a ray parallel to a slab axis hits within the
+//                                other slabs, misses outside, never /0.
+//   - INVALID AABB SKIPPED     : an inverted box (min > max) yields no hit.
+//   - ORIGIN INSIDE BOX HITS   : a ray starting inside a box hits it at t=0.
+//   - BUDGET CLAMP HOLDS       : NearestUnitHit walks at most kMaxRaycastUnits
+//                                entries — a hit past the budget is unseen.

+// swfoc_overlay/overlay_hotkey_matrix.h — Phase 6 hotkey conflict matrix.
+//
+// Phase 6 (iter 304-307) expanded the overlay's hotkey surface into power-user
+// features. iter-307 (spec line 65) is the Phase 6 CLOSE-OUT, whose headline
+// deliverable is the HOTKEY CONFLICT MATRIX: a per-binding "intercept-or-
+// passthrough decision" for every F-key the overlay touches, so the overlay's
+// claim on the keyboard can never silently collide with the host game's own
+// F-key handling (spec acceptance line 39).
+//
+// THE CONFLICT
+// ------------
+// The overlay subclasses the host game's WndProc (iter-514) so ImGui sees
+// mouse / keyboard messages. overlay_input.h::ShouldSwallowMessage already
+// routes the GENERAL case — a click / keystroke over an ImGui widget. The
+// F-key HOTKEYS are different: they fire whether or not a widget has focus,
+// so when the WndProc detour sees a WM_KEYDOWN for an F-key it needs a
+// SEPARATE, explicit decision:
+//
+//   - INTERCEPT  : the overlay acts on the key AND swallows the message — the
+//                  game never sees it. Used for every F-key the overlay binds,
+//                  so one press never both toggles an overlay feature AND
+//                  triggers whatever the game maps that key to.
+//   - PASSTHROUGH: the overlay does not claim the key; the message flows to
+//                  the game untouched. Used for every F-key the overlay does
+//                  NOT bind, so the game keeps full use of its own keyboard.
+//
+// THE VISIBILITY GATE — how the conflict is "worked around"
+// --------------------------------------------------------
+// An overlay-bound F-key is intercepted ONLY while the overlay is on screen.
+// Toggle the overlay off (F1) and every other overlay hotkey reverts to
+// passthrough — the operator gets the game's full keyboard back the instant
+// the tool is hidden. F1 itself is the sole exception: it is intercepted
+// UNCONDITIONALLY (the `intercept_when_hidden` flag), because the master
+// visibility toggle must stay reachable to bring a hidden overlay back.
+//
+// This header is the AUTHORITATIVE matrix: one HotkeyBinding row per F1..F12,
+// carrying the disposition, the operator-trust capability status (guardrail
+// 1007), the game-side conflict note, and the rationale. Two consumers share
+// this single source of truth:
+//   - the deferred overlay.cpp WndProc detour calls OverlayInterceptsKey() to
+//     decide whether to swallow an F-key WM_KEYDOWN;
+//   - overlay_hotkey_matrix_test.cpp pins the matrix AND cross-checks the F4 /
+//     F6 / F7 / F8 rows against the Phase 6 kernels (overlay_pause_hotkey.h,
+//     overlay_camera_bookmarks.h) so the matrix can never drift from them.
+//
+// RED-GREEN REGRESSION PINS (overlay_hotkey_matrix_test.cpp)
+// ---------------------------------------------------------
+//   - MATRIX COVERS F1..F12         : exactly 12 rows, VK codes contiguous
+//                                     0x70..0x7B — a missing key fails.
+//   - F1 INTERCEPTS EVEN WHEN HIDDEN: OverlayInterceptsKey(VK_F1, false) is
+//                                     true — an old form gating F1 on
+//                                     visibility could never un-hide the
+//                                     overlay and fails.
+//   - HOTKEYS YIELD THE KEYBOARD    : F3 / F4 / F6 / F7 / F8 are NOT
+//     WHEN HIDDEN                     intercepted with overlayVisible=false —
+//                                     an old form swallowing them while hidden
+//                                     starves the game and fails.
+//   - UNBOUND KEYS ALWAYS PASS      : F5 / F9 / F10 / F11 / F12 are never
+//     THROUGH                         intercepted, visible or hidden.
+//   - F10 IS NEVER INTERCEPTED      : F10 is a Win32 system key — swallowing it
+//                                     would break the host window menu.
+//   - INTERCEPT IMPLIES A BOUND     : disposition Intercept only ever pairs
+//     LIVE/PHASE2 STATUS              with status Live / Phase2Pending;
+//                                     Deferred / Unbound always pair with
+//                                     Passthrough — a row violating that fails.
+//   - F4 STATUS TRACKS THE WIRE     : the F4 row's status mirrors
+//                                     overlay_pause_hotkey.h::kGameSpeedWire-
+//                                     Status — it flips to LIVE in lockstep.
+//   - CAMERA KEYS ARE F6/F7/F8      : the camera-bookmark rows match
+//                                     overlay_camera_bookmarks.h::CameraBook-
+//                                     markHotkey(0/1/2).
+//
+// THREADING: the matrix is immutable constexpr data — every consumer only

+// state, no mutex; safe to call from the WndProc detour on the host UI thread.

+// swfoc_overlay/overlay_hotkey_matrix_test.cpp — unit test for
+// overlay_hotkey_matrix.h (Phase 6 close-out part 1/2, iter 547 / spec iter-307).
+//
+// iter-307 is the Phase 6 close-out; its headline deliverable is the HOTKEY
+// CONFLICT MATRIX — a per-binding intercept-or-passthrough decision for every
+// F-key the overlay touches (spec acceptance line 39). overlay_hotkey_matrix.h
+// holds the pure kernel: the 12-row matrix, the VK<->F-key helpers, and
+// OverlayInterceptsKey() — the WndProc-detour decision the deferred overlay.cpp
+// keyboard handler will call on every F-key WM_KEYDOWN.
+//
+// This test pins the matrix AND cross-checks the F4 / F6 / F7 / F8 rows against
+// the Phase 6 kernels they describe (overlay_pause_hotkey.h,
+// overlay_camera_bookmarks.h) so the matrix can never drift from them. The
+// integration section drives OverlayInterceptsKey through a full operator
+// session — overlay hidden -> F1 un-hides -> overlay hotkeys go live -> F1
+// re-hides -> the keyboard reverts to the game.
+//
+// overlay_hotkey_matrix.h is header-only and std-only (<cstddef> only). The
+// two Phase 6 kernels this test cross-checks pull in <cstdio> / <string> /
+// <deque> / <functional> / <mutex> through their include chains — so -pthread
+// is load-bearing for the threading runtime. No game, no pipe, no ImGui, no
+// Windows. Build + run via build_hotkey_matrix_test.bat.

+//                                      true — a hidden overlay still claims F1.

+// swfoc_overlay/overlay_input.h — Phase 3 host-window input routing decision.
+//
+// Phase 3's interactive widgets need mouse + keyboard input, but the overlay
+// shares ONE window with the host game. Phase 1-2 deliberately never detoured
+// the host WndProc (it polls F1 from a worker thread) so it could not steal
+// input. Phase 3 changes that: overlay.cpp now subclasses the host WndProc so
+// ImGui sees mouse/keyboard messages.
+//
+// The hazard a WndProc detour introduces is INPUT BLEED, in both directions:
+//   - forward too much   -> a click on an overlay button ALSO commands the
+//                           game (e.g. orders the selected unit to move).
+//   - forward too little -> the game stops responding to the mouse whenever
+//                           the overlay is on screen, even over empty space.
+//
+// ShouldSwallowMessage() is the pure decision at the heart of that detour:
+// given a window message and ImGui's per-frame WantCapture* flags, it answers
+// "does the overlay consume this, or does it pass through to the game?". It is
+// dependency-free (no <windows.h>, no ImGui) so the routing rule is unit-
+// tested with a plain g++ — see overlay_input_test.cpp (build_input_test.bat),
+// mirroring overlay_action_queue.h / overlay_actions.h.

+// swfoc_overlay/overlay_input_test.cpp — unit test for overlay_input.h.
+//
+// overlay_input.h is dependency-free (no <windows.h>, no ImGui, no D3D9, no
+// bridge). This test compiles with a plain g++ and needs no game and no
+// window — it exercises the pure WndProc-detour swallow decision. Build + run
+// via build_input_test.bat.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+// The WndProc detour is dangerous to get wrong: it shares one window with the
+// host game. The three checks tagged "PIN" below fail on the two most likely
+// regressions:
+//   - dropping the visibility gate  -> the overlay steals input even when
+//                                      hidden (F1 toggled off freezes the game).
+//   - "swallow everything while visible" -> in-game mouse control freezes
+//                                      whenever the overlay is on screen, even
+//                                      over empty space away from any widget.
+// They pass ONLY on the correct three-gate form in ShouldSwallowMessage().

+// =============================================================================
+// swfoc_overlay/overlay_inspector.h — Phase 5 click-to-inspect panel kernel.
+//
+// Phase 5 (iter 297-303) makes the overlay click-aware. iter-297 pinned the
+// engine's D3D transform matrices, iter-298 (overlay_cursor_ray.h) turns a
+// cursor pixel into a world-space pick ray, and iter-299 (overlay_hit_test.h)
+// walks the visible-unit AABB set to decide WHICH unit the operator clicked.
+// iter-300 (spec line 58) is the next link: take that picked unit and present
+// it — an "Inspector" overlay panel showing hull / shield / owner / type /
+// position. The write-side action buttons (kill / heal / teleport / swap-owner
+// / make-invuln) are iter-301; this iter is READ-ONLY display.
+//
+// This header is the pure decision kernel of that panel — the logic that has a
+// right and a wrong answer and so must be pinned by a unit test before the
+// ImGui::Begin("Inspector") glue in overlay.cpp depends on it:
+//
+//   1. HealthFraction() / HealthPercent() — turn a (current, max) pair into a
+//      clamped [0,1] bar fraction and a 0..100 percent. Over-heal (current >
+//      max) and a zero / negative max are real engine states the display must
+//      survive without overflowing the bar.
+//   2. FactionName()         — map an owner faction slot to a readable name.
+//   3. FormatHealthLabel() / FormatPositionLabel() — the exact text the panel
+//      rows render; deterministic so a test can pin it character-for-character.
+//   4. FindUnitByHandle()    — resolve an engine GameObject token to its entry
+//      in the visible-unit info set (the parallel of iter-299's UnitAabb set).
+//   5. OpenInspectorFor()    — turn an iter-299 UnitHit into a populated panel,
+//      resolving the unit by its engine HANDLE (drift-resistant) rather than by
+//      the raw array index.
+//   6. UpdateInspectorPanel() — the click controller: a valid pick opens /
+//      replaces the panel; a miss-click leaves the panel exactly as it was, so
+//      clicking empty ground never yanks the inspector shut.
+//   7. RefreshInspectorPanel() — re-resolve the open panel against a fresh
+//      snapshot each frame so hull / shield / position stay live, and auto-
+//      close the panel when the inspected unit dies or leaves the field.
+//
+// WHERE THE DATA COMES FROM
+// -------------------------
+// UnitInfo is a self-contained POD — the kernel never owns engine memory. The
+// overlay.cpp glue (deferred; lands after iter-302 extends HudSnapshot with the
+// per-unit set) populates it: handle + position + AABB from the iter-104 /
+// iter-179 visible-unit enumeration, hull / shield / owner / type from the
+// iter-167+ getters. The kernel only decides how that data is shown.
+//
+// RED-GREEN REGRESSION PINS (overlay_inspector_test.cpp)
+// -----------------------------------------------------
+//   - CLICK OPENS INSPECTOR  : a valid UnitHit opens the panel on the picked
+//                              unit — a "no inspector" old form never opens.
+//   - MISS LEAVES PANEL      : UpdateInspectorPanel on a miss-pick returns the
+//                              prior panel unchanged — a "close on every
+//                              click" old form would flicker the panel shut.
+//   - HEALTH PERCENT CLAMPS  : over-heal saturates at 100%, negative hull at
+//                              0%, max <= 0 reads "n/a" — a bare current / max
+//                              old form overflows past 100%.
+//   - DEAD UNIT AUTO-CLOSES  : RefreshInspectorPanel against a snapshot missing
+//                              the inspected handle closes the panel — a
+//                              "never refresh" old form renders a phantom.
+//   - FACTION NAME CORRECT   : FactionName(0) is "Rebel", not "Unknown" — a
+//                              swapped / missing switch arm fails.
+//   - RESOLVE BY HANDLE      : OpenInspectorFor finds the unit by handle, so a
+//                              reordered unit list still inspects the right
+//                              unit — a raw-index old form picks the wrong one.

+// swfoc_overlay/overlay_inspector_actions.h — Phase 5 inspector action kernel.
+//
+// Phase 5 (iter 297-303) makes the overlay click-aware. iter-298
+// (overlay_cursor_ray.h) turns a cursor pixel into a world-space pick ray,
+// iter-299 (overlay_hit_test.h) walks the visible-unit AABB set to name the
+// unit under the cursor, and iter-300 (overlay_inspector.h) presents that
+// unit in a read-only "Inspector" panel. iter-301 (spec line 59) is the
+// write-side: five action buttons on the inspector panel —
+//
+//   Kill        SWFOC_KillUnit(obj_addr)                    iter-110 LIVE
+//   Heal        SWFOC_HealUnitLua(unit_lua_expr)            iter-154 LIVE
+//   Teleport    SWFOC_TeleportUnitLua(unit_lua_expr, pos)   iter-151 LIVE
+//   SwapOwner   SWFOC_ChangeUnitOwner(unit_lua_expr, plr)   iter-108 LIVE
+//   MakeInvuln  SWFOC_MakeUnitInvulnLua(unit_lua_expr, b)   iter-110 LIVE
+//
+// All five wires are already LIVE — iter-301 ships NO new bridge wire. This
+// header is the pure kernel that turns the inspected UnitInfo (the unit the
+// operator clicked) into a dispatch-ready ActionRequest for each button. The
+// ImGui::Begin("Inspector") glue (deferred; lands after iter-302 extends
+// HudSnapshot with the per-unit set) only renders five buttons and hands the
+// ActionRequest to the iter-513 ActionQueue — the deciding logic is here so a
+// unit test pins it before the render path depends on it.
+//
+// EXACT-UNIT TARGETING — THE HONEST LIMITATION
+// --------------------------------------------
+// The inspector picked ONE specific unit by raycast and knows its exact
+// engine handle (UnitInfo::handle == the GameObject address).
+//
+//   - Kill is address-based: SWFOC_KillUnit takes a numeric obj_addr, so
+//     BuildInspectorKill targets the EXACT picked unit. No ambiguity.
+//
+//   - Heal / Teleport / SwapOwner / MakeInvuln are engine-METHOD wires: they
+//     take a unit Lua *expression*, not an address, and SWFOC exposes no
+//     "object from address" engine-Lua function. So these four fall back to
+//     Find_First_Object("<type>") — the first live instance of the picked
+//     unit's type — exactly as the Phase 3 widgets do (overlay.cpp iter-524).
+//     When several units share a type the method wires may act on a sibling.
+//
+// This is overlay-interactive.md honest-defer #2 (cursor-hit-unit detection):
+// a documented blocker with a deliberate workaround, not a failure. When a
+// future SWFOC_GetUnitAtScreenCoords or address->handle resolution wire lands,
+// only InspectorUnitLuaExpr() changes — the five builders below stay put.
+//
+// RED-GREEN REGRESSION PINS (overlay_inspector_actions_test.cpp)
+// -------------------------------------------------------------
+//   - KILL TARGETS EXACT HANDLE : BuildInspectorKill's Lua embeds the picked
+//                                 unit's exact handle as the obj_addr — a
+//                                 "kill the first of this type" old form
+//                                 would drop the address.
+//   - HEAL WIRE NAME CORRECT    : the heal Lua names SWFOC_HealUnitLua — a
+//                                 typo'd / wrong wire name fails.
+//   - HEAL IS SINGLE-ARG        : the heal Lua is the no-arg :Heal() shape —
+//                                 a two-arg old form (copied from Teleport)
+//                                 fails.
+//   - SWAPOWNER USES NEW OWNER  : BuildInspectorSwapOwner re-owns to the
+//                                 REQUESTED slot, not the unit's current
+//                                 owner — a "swap to current owner" old form
+//                                 is a no-op and fails.
+//   - INVULN BOOL TOGGLES       : (unit,true) emits "true" + a "Make Invuln"
+//                                 label; (unit,false) emits "false" + a
+//                                 "Clear Invuln" label.
+//   - EXPR ESCAPES TYPE NAME    : a unit type carrying a quote is escaped in
+//                                 the Find_First_Object literal — a raw-
+//                                 concat old form breaks the Lua literal.
+//   - LABEL NAMES THE UNIT      : every ActionRequest label embeds the unit
+//                                 type, so the toast / recent-actions slot
+//                                 identifies the unit, not a generic verb.
+//
+// Pure, header-only, std-only (<string>, plus the include chain). No ImGui,
+// no Windows, no bridge. Unit-tested with a plain g++
+// (build_inspector_actions_test.bat).

+// swfoc_overlay/overlay_inspector_test.cpp — unit test for overlay_inspector.h
+// (Phase 5 cont., iter 539 / spec iter-300).
+//
+// iter-300 is the click-to-inspect link of Phase 5: once iter-299's raycast
+// names the unit under the cursor, this iter presents it — an "Inspector"
+// overlay panel showing hull / shield / owner / type / position (read-only;
+// the write-side action buttons are iter-301). overlay_inspector.h holds the
+// pure panel logic — clamped health math, faction naming, the exact row text,
+// handle resolution, and the open / update / refresh controller. This test
+// pins all of it so the iter-300 ImGui::Begin("Inspector") glue can depend on
+// it build-only.
+//
+// The integration section wires the kernel to its real upstream: it builds a

+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - CLICK OPENS INSPECTOR : a valid UnitHit opens the panel on the unit.
+//   - MISS LEAVES PANEL     : UpdateInspectorPanel on a miss returns the prior
+//                             panel unchanged — no flicker-shut.
+//   - HEALTH PERCENT CLAMPS : over-heal -> 100%, negative -> 0%, max<=0 ->
+//                             "n/a" — a bare current/max overflows past 100.
+//   - DEAD UNIT AUTO-CLOSES : RefreshInspectorPanel against a snapshot missing
+//                             the inspected handle closes the panel.
+//   - FACTION NAME CORRECT  : FactionName(0) is "Rebel", not "Unknown".
+//   - RESOLVE BY HANDLE     : OpenInspectorFor finds the unit by handle, so a
+//                             reordered list still inspects the right unit.

+// swfoc_overlay/overlay_minimap.h — Phase 4 tactical-minimap kernel.
+//
+// Phase 4 (iter 292-296) lets the operator place units by drag-drop. iter-292
+// shipped a fixed 200x200 spawn pad (overlay_dragdrop.h). iter-293 adds a
+// 256x256 top-down MINIMAP: a richer drag-drop target that also plots a dot
+// for every spawn the operator has dropped, so they can see at a glance where
+// their units landed across the battlefield.
+//
+// This header is the PURE kernel of the minimap — the parts that have a right
+// and a wrong answer and so must be pinned by a unit test before the ImGui
+// render glue in overlay.cpp depends on them:
+//
+//   1. WorldToMinimap() — project a world (X, Y) onto a minimap pixel, so a
+//      spawn marker draws where it actually is. A flipped Y axis would draw
+//      every dot upside-down.
+//   2. MinimapToWorld() — map a minimap drop pixel back to a world (X, Y, 0).
+//      It is the EXACT inverse of WorldToMinimap; the test pins the round
+//      trip. It delegates to overlay_dragdrop.h::DropPadToWorld — the minimap
+//      is just a larger drop pad — so the two coordinate maps cannot diverge.
+//   3. SpawnMarkerRing — a fixed-capacity ring of recent spawn-drop points.
+//      The eviction order (oldest out when full) has a right answer worth
+//      pinning so the minimap's dot history stays stable.
+//
+// HONEST DEFER (overlay-interactive.md line 51): a true minimap needs the
+// engine heightmap + ortho-camera RVAs to know the real tactical-map extent
+// and to draw live engine-unit dots from SWFOC_EnumerateUnits. Neither is
+// pinned. iter-293 therefore ships the interim: a flat 2D grid over a fixed
+// coarse world extent (kMinimapHalfExtent), and the dots plot the operator's
+// OWN recent spawn drops — data the overlay already has — rather than the
+// live engine unit list. Live per-unit dots arrive in Phase 5 once HudSnapshot
+// carries per-unit positions (spec iter-302).
+//
+// Pure, header-only, std-only — no ImGui, no Windows, no bridge. Unit-tested
+// with a plain g++ (build_minimap_test.bat).

+// =============================================================================
+// swfoc_overlay/overlay_minimap_test.cpp — unit test for overlay_minimap.h
+// (Phase 4 cont., iter 530 / spec iter-293).
+//
+// iter-293 adds the 256x256 tactical minimap. overlay_minimap.h holds the pure
+// pieces: WorldToMinimap (project a world point to a minimap pixel — draws the
+// spawn-marker dots), MinimapToWorld (map a drop pixel back to the world — the
+// drag-drop target), and SpawnMarkerRing (the fixed-capacity dot history).
+// This test pins all three so the ImGui render glue in overlay.cpp can depend
+// on them build-only.
+//
+// overlay_minimap.h includes overlay_dragdrop.h (SpawnDrop, DropPadToWorld);
+// this test also #includes overlay_actions.h to prove a MinimapToWorld result
+// composes into BuildSpawnUnitCommand — the same integration-pin idea as the
+// sibling overlay tests. Build + run via build_minimap_test.bat — no game.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - ORIGIN -> CENTER     : world (0,0) must map to the minimap center. An
+//                            off-by-one in the normalize shifts every dot.
+//   - SCREEN-UP IS +Y      : world +Y (north) must map to the TOP of the
+//                            minimap (py small). A flipped Y axis draws every
+//                            spawn dot upside-down and fails this pin.
+//   - ROUND-TRIP IDENTITY  : MinimapToWorld(WorldToMinimap(p)) == p for any
+//                            on-map point. A flipped axis or a normalize
+//                            off-by-one breaks the round trip even if each
+//                            half looks plausible alone.
+//   - OLDEST EVICTED FIRST : once SpawnMarkerRing is full, Push() must evict
+//                            the OLDEST marker (At(0)), not the newest.

+// swfoc_overlay/overlay_pause_hotkey.h — Phase 6 pause/resume-hotkey kernel.
+//
+// Phase 6 (iter 304-307) expands the overlay's hotkey surface into power-user
+// features. iter-306 (spec line 64) is the PAUSE / RESUME hotkey bound to F4:
+//
+//   - One F4 press freezes the simulation (game speed -> 0).
+//   - The next F4 press un-freezes it, restoring the running speed the
+//     operator was at before the pause.
+//   - The overlay footer shows the current game speed so the operator
+//     always knows whether time is moving.
+//
+// This header is the pure kernel: the F4 toggle state machine (PauseToggle),
+// the SWFOC_SetGameSpeed command builder, and the SetGameSpeed delivery
+// status. The overlay.cpp glue (deferred, build-only verifiable — exactly
+// like every Phase 5/6 kernel iter) only polls F4 and hands Toggle()'s
+// ActionRequest to the iter-513 ActionQueue; the deciding logic is here so a
+// unit test pins it before the input path depends on it.
+//
+// WIRE FACTS + HONEST DEFER (swfoc_lua_bridge/lua_bridge.cpp, re-read 2026-05-21)
+// -----------------------------------------------------------------------------
+//   SWFOC_SetGameSpeed(speed) IS a registered, callable bridge wire
+//   (Lua_SetGameSpeed, registered :8217). But its Phase-1 body only RECORDS
+//   the requested speed into g_pendingGameSpeed and returns
+//       "OK: game speed recorded (Phase 2 hook pending)"
+//   — the engine's SimulationRate global is NOT yet patched. lua_bridge.cpp
+//   :3292 documents the Phase 2 RE blocker (the SimulationRate global was
+//   searched 2026-04-23, no direct string hit). So a bridge call that
+//   "succeeds" does NOT freeze or slow the game today.
+//
+//   The editor mirrors this: BridgeDirectorDispatcher.cs and
+//   BridgeSpeedDispatcher.cs both label SWFOC_SetGameSpeed
+//   "PHASE 2 PENDING — UI command disabled".
+//
+//   Per overlay-interactive.md line 64, iter-306 ships the F4 hotkey wire-up
+//   ANYWAY: the toggle, the command builder, and the footer speed display
+//   are all real and tested. The kernel surfaces the SetGameSpeed status
+//   (operator-trust pattern, guardrail 1007) via GameSpeedWireStatusText()
+//   so the overlay footer warns "PHASE 2 PENDING" instead of pretending the
+//   game froze. The MOMENT the editor-100 spec flips SetGameSpeed LIVE, a
+//   maintainer flips kGameSpeedWireStatus to Live — the WIRE STATUS pin in
+//   the test fires to remind them — and the F4 hotkey goes LIVE with zero
+//   further kernel change.
+//
+// RED-GREEN REGRESSION PINS (overlay_pause_hotkey_test.cpp)
+// --------------------------------------------------------
+//   - TOGGLE PAUSES THEN RESUMES   : the first F4 emits SetGameSpeed(0), the
+//                                    second emits SetGameSpeed(running) — an
+//                                    old form stuck on SetGameSpeed(0) fails.
+//   - RESUME RESTORES RUNNING SPEED: a 3x running speed is restored on
+//                                    resume — an old form hardcoding 1x fails.
+//   - SET-SPEED-WHILE-PAUSED       : SetRunningSpeed while paused updates the
+//     DOESN'T UNPAUSE                resume target WITHOUT un-pausing — an old
+//                                    form that un-pauses on SetRunningSpeed
+//                                    fails.
+//   - REJECT NON-POSITIVE SPEED    : SetRunningSpeed rejects 0 / negative /
+//                                    NaN / inf and leaves the speed intact —
+//                                    an old form that stores 0 (making resume
+//                                    a silent no-op) fails.
+//   - CURRENT SPEED REFLECTS PAUSE : CurrentSpeed() is 0 while paused, the
+//                                    running speed while running — drives the
+//                                    footer; an old form ignoring pause fails.
+//   - HOTKEY IS F4                 : the labels name F4 — an old form labeling
+//                                    F3 / F5 fails.
+//   - PLAIN NUMBER ARG             : BuildSetGameSpeedCommand emits a bare
+//                                    number literal — a copy-from-SWFOC_*Lua
+//                                    old form that LuaQuotes the speed fails.
+//   - WIRE STATUS IS PHASE-2-PENDING: kGameSpeedWireStatus is Phase2Pending —
+//                                    flips (and the test reminds a maintainer)
+//                                    only when SetGameSpeed goes LIVE.
+//
+// THREADING: PauseToggle is touched ONLY by the render / input thread —
+// Toggle() at the F4 hotkey site, CurrentSpeed() / IsPaused() while drawing
+// the footer. The background action worker drains the ActionQueue but never
+// touches this state. Render-thread-confined, so — like
+// overlay_camera_bookmarks.h's CameraBookmarks — it needs no mutex.
+//
+// Pure, header-only, std-only. Reuses FormatCoord from overlay_actions.h and
+// ActionRequest from overlay_action_queue.h — no new type, no ImGui, no
+// Windows, no bridge. Unit-tested with a plain g++ (build_pause_hotkey_test.bat).

+// swfoc_overlay/overlay_phase3_catalog.h — Phase 3 widget capability catalog.
+//
+// Phase 3 (iter 287-291) gave the overlay five interactive "Actions" widgets:
+// Spawn / Make Invuln / Kill / Teleport / Faction Switch. Each issues an engine
+// mutation through one SWFOC_* bridge wire (overlay_actions.h builders). The
+// operator-trust pattern (guardrail 1007) requires every operator-facing button
+// to surface its capability status so a click is never confused with a
+// confirmed engine-state change.
+//
+// This header is the AUTHORITATIVE Phase 3 widget catalog: one Phase3Widget
+// entry per button — its label, the bridge wire it dispatches, and that wire's
+// capability status. Two consumers share this single source of truth:
+//   - overlay.cpp RenderPhase3CapabilityTable() draws a per-widget badge row
+//     straight from kPhase3Widgets — the badge can never drift from the catalog.
+//   - overlay_phase3_catalog_test.cpp pins the catalog (count, labels, wires,
+//     all-LIVE status, badge text) AND cross-checks each declared wire against
+//     the matching overlay_actions.h builder so a badge can never lie.
+//
+// It replaces the iter-525 static "Wires (all LIVE): ..." footer string, which
+// was hand-maintained and could silently drift from the wires the buttons
+// actually call (the iter-380 / iter-388 stale-string-drift family of bugs).
+//
+// Pure, header-only, std-only — no ImGui, no Windows, no bridge. Unit-tested
+// with a plain g++ (build_phase3_catalog_test.bat).
+//
+// All five wires are LIVE — verified registered in swfoc_lua_bridge/
+// lua_bridge.cpp (2026-05-21): SWFOC_SpawnUnitLua, SWFOC_MakeUnitInvulnLua,
+// SWFOC_KillUnit, SWFOC_TeleportUnitLua, SWFOC_ChangeUnitOwner. If a future

+// swfoc_overlay/overlay_phase4_close_test.cpp — Phase 4 close-out integration
+// test (Phase 4 close-out, iter 533 / spec iter-296).
+//
+// Phase 4 (iter 292-296) gave the overlay a drag-drop tactical-spawn surface,
+// shipped one kernel per iteration, each with its own dedicated unit test:
+//
+//   iter-292/529  overlay_dragdrop.h     drag payload + pad->world map   65/0
+//   iter-293/530  overlay_minimap.h      256x256 minimap + marker ring  135/0
+//   iter-294/531  overlay_preview_ring.h faction-tinted drop preview     74/0
+//   iter-295/532  overlay_spawn_gate.h   multi-player-safety gate        53/0
+//
+// Those four tests pin each kernel IN ISOLATION (327 checks total). This file
+// is the Phase 4 CLOSE-OUT test: it wires the four kernels — plus the spawn
+// builder overlay_actions.h::BuildSpawnUnitCommand — TOGETHER and exercises
+// the complete end-to-end drag-drop spawn PIPELINE exactly as overlay.cpp's
+// RenderActionsWindow / RenderSpawnPad / RenderMinimap / DispatchSpawnDrop
+// chain them at runtime. Its value is the SEAMS between kernels, which no
+// isolation test can see.
+//
+// Naming note (carried from iter-527's Phase 3 close-out): the spec iter-296
+// row writes "Iter296Phase4DragDropTests.cs". The `.cs` name predates the
+// overlay's all-C++ native-exe test infra — a C# test cannot exercise a C++
+// header. This file IS the spec iter-296 close-out test in the established
+// pattern (overlay_dragdrop_test.cpp, overlay_minimap_test.cpp, ...).
+//
+// SPEC iter-296 RED-GREEN PINS (overlay-interactive.md line 54)
+// ------------------------------------------------------------
+//   [1] DROP WITHOUT SELECTION BLOCKS : a drop fired with no valid tactical
+//       local player (gate closed) — or with no draggable unit-type payload —
+//       produces NO spawn command and records NO minimap marker. The "no gate
+//       at all" old form, where a drop always spawned, fails this pin.
+//   [2] DROP WITH SELECTION FIRES     : a drop fired with a valid local-player
+//       slot and a valid dragged unit type produces a real
+//       `return SWFOC_SpawnUnitLua(...)` Lua line at the resolved world point.
+//   [3] PREVIEW RING RENDERS          : the preview-ring kernel yields a
+//       positive, in-band radius and a visible faction-tinted color for every
+//       frame of the breathe cycle — ImGui is never handed a degenerate ring.
+//   [4] MINIMAP SHOWS UNITS           : every spawn that fires records a
+//       marker, and each retained marker projects onto an on-map minimap
+//       pixel — the drop becomes a dot the operator can see.
+//
+// All five headers are header-only and std-only. Build + run via
+// build_phase4_close_test.bat — no game, no pipe, no ImGui, no bridge.

+// swfoc_overlay/overlay_phase5_close_test.cpp — Phase 5 close-out integration
+// test (Phase 5 close-out part 1/2, iter 542 / spec iter-303).
+//
+// Phase 5 (iter 297-303) made the overlay CLICK-AWARE: the operator clicks an
+// in-game unit and an inspector panel opens with the unit's stats and five
+// action buttons. It shipped one kernel per iteration, each with its own
+// dedicated unit test:
+//
+//   iter-297       (RE pass)               projection-matrix RVA pins   (doc)
+//   iter-298       overlay_cursor_ray.h    cursor pixel -> world ray    147/0
+//   iter-299       overlay_hit_test.h      ray -> nearest unit AABB     101/0
+//   iter-300       overlay_inspector.h     UnitHit -> inspector panel    84/0
+//   iter-301       overlay_inspector_actions.h  panel -> 5 ActionRequests 68/0
+//   iter-302       overlay_unit_aabb.h     HudSnapshot unit-AABB set     65/0
+//
+// Those five tests pin each kernel IN ISOLATION (465 checks total). This file
+// is the Phase 5 CLOSE-OUT test: it wires the five kernels — plus the bridge
+// command builders overlay_actions.h and the iter-513 ActionQueue — TOGETHER
+// and exercises the complete end-to-end CLICK-TO-INSPECT pipeline exactly as
+// overlay.cpp's deferred RenderInspector / OnClick chain runs it at runtime.
+// Its value is the SEAMS between kernels, which no isolation test can see.
+//
+// Naming note (carried from iter-527's Phase 3 and iter-533's Phase 4
+// close-outs): the spec iter-303 row writes "Iter303Phase5InspectorTests.cs".
+// The `.cs` name predates the overlay's all-C++ native-exe test infra — a C#
+// test cannot exercise a C++ header. This file IS the spec iter-303 close-out
+// test in the established pattern (overlay_phase4_close_test.cpp, ...).
+//
+// SPEC iter-303 RED-GREEN PINS (overlay-interactive.md acceptance line 33)
+// -----------------------------------------------------------------------
+//   [1] CLICK PICKS THE UNIT     : a cursor click whose screen pixel is the
+//       projection of a unit's world centre picks THAT unit through the full
+//       pipeline (CursorRay -> PickUnitInSet -> UnitHit). The honest-defer
+//       empty AABB set produces a clean miss, never a phantom hit. An "always
+//       miss" or "pick array slot 0" old form fails.
+//   [2] INSPECTOR SHOWS THE UNIT : a hit opens an inspector panel carrying the
+//       clicked unit's hull / shield / owner / type / position, formatted by
+//       the iter-300 label helpers. A "never open" old form fails.
+//   [3] ACTION BUTTONS DISPATCH-READY : the five inspector actions (Kill /
+//       Heal / Teleport / SwapOwner / MakeInvuln) each build a real
+//       `return SWFOC_*` bridge line; Kill targets the EXACT picked handle
+//       even when two units share a type. A "kill first-of-type" old form
+//       drops the address and fails.
+//   [4] MISS-CLICK KEEPS THE PANEL : clicking empty ground leaves the open
+//       inspector exactly as it was. A "close on every click" old form
+//       flickers the panel shut and fails.
+//
+// All seven headers are header-only and std-only. Build + run via
+// build_phase5_close_test.bat — no game, no pipe, no ImGui, no bridge.

+// hotkey-routing pipeline exactly as overlay.cpp's deferred WndProc detour
+// runs it — a WM_KEYDOWN arrives, the matrix decides intercept-or-passthrough
+// (OverlayInterceptsKey), and on intercept the F-key is routed to its kernel.
+// Its value is the SEAM between the matrix-as-router and the three kernels —
+// the part no isolation test can see.

+// Naming note (carried from iter-527's Phase 3, iter-533's Phase 4 and
+// iter-542's Phase 5 close-outs): the spec iter-307 row writes
+// "Iter307Phase6HotkeysTests.cs". The `.cs` name predates the overlay's
+// all-C++ native-exe test infra — a C# test cannot exercise a C++ header.
+// This file IS the spec iter-307 close-out test in the established pattern
+// (overlay_phase4_close_test.cpp, overlay_phase5_close_test.cpp, ...).

+// -----------------------------------------------------------------------
+//   [1] EVERY OVERLAY HOTKEY ROUTES TO ITS KERNEL : the matrix's F3 / F4 /
+//       F6 / F7 / F8 rows agree, key-for-key, with each kernel's own hotkey
+//       constant (kPauseHotkeyFKey, CameraBookmarkHotkey). A matrix that
+//       drifted from a kernel — or a kernel that bound a key the matrix does
+//       not catalogue — fails.
+//   [2] THE MATRIX GATES WHETHER A HOTKEY FIRES : a key the matrix passes
+//       through never reaches a kernel. With the overlay VISIBLE F3 / F4 /
+//       F6 / F7 / F8 fire; with it HIDDEN they all revert to passthrough and
+//       the kernels stay untouched — only F1 fires while hidden. An old form
+//       that swallowed an overlay hotkey off-screen starves the game and
+//       fails.
+//   [3] EACH KERNEL'S HOTKEY ACTION IS DISPATCH-READY : a routed F4 builds a
+//       real `return SWFOC_SetGameSpeed` line; a routed F6 a real
+//       `return SWFOC_SetCameraPos` line; a routed-then-confirmed F3 a batch
+//       of real `return SWFOC_ChangeUnitOwner` lines. An F6 on an UNSET slot
+//       builds an empty-Lua request the router must NOT enqueue.
+//   [4] OPERATOR-TRUST STATUS IS CONSISTENT ACROSS THE SEAM : the matrix's
+//       F4 row status mirrors overlay_pause_hotkey.h::kGameSpeedWireStatus
+//       (Phase2Pending today) — the matrix never claims LIVE for a
+//       PHASE-2-PENDING wire; every Intercept row carries a bound
+//       Live/Phase2Pending status.
+//
+// All five headers are header-only and std-only. Build + run via
+// build_phase6_close_test.bat — no game, no pipe, no ImGui, no bridge.

+// swfoc_overlay/overlay_preview_ring.h — Phase 4 drop-point preview-ring kernel.
+//
+// Phase 4 (iter 292-296) lets the operator place units by drag-drop. iter-292
+// shipped the spawn pad, iter-293 the minimap. iter-294 (spec line 52) adds a
+// PREVIEW RING: while the operator is dragging a unit-type over a spawn target,
+// a faction-tinted, gently pulsing ring is drawn at the cursor so they can see
+// exactly where the unit will land BEFORE they release the mouse. The ring is
+// a pure overlay hint drawn on ImGui's foreground draw list — there is no
+// game-side draw (overlay-interactive.md iter-294: "Preview ring is overlay-
+// only; no game-side draw").
+//
+// This header is the PURE kernel of that feature — the parts that have a right
+// and a wrong answer and so must be pinned by a unit test before the ImGui
+// foreground-draw-list glue in overlay.cpp depends on them:
+//
+//   1. PreviewRingColor()  — map the Phase 4 Faction-combo index to the ring
+//      tint. The spec requires "Ring color = faction tint per iter-92 LED
+//      tinting"; a wrong mapping would tint a Rebel spawn Imperial chrome.
+//   2. FramePhase01()      — fold the monotonic Present frame counter into a
+//      normalized [0,1) animation phase. An un-wrapped phase would make the
+//      ring grow without bound instead of breathing.
+//   3. PreviewRingRadius() — the pulsing radius for a given phase. A sawtooth
+//      instead of a triangle, or an un-clamped negative result, would either
+//      jump the ring or hand ImGui a negative-radius circle.
+//
+// RED-GREEN REGRESSION PINS (overlay_preview_ring_test.cpp)
+// --------------------------------------------------------
+//   - FACTION TINT CORRECT : PreviewRingColor(0) is REBEL amber, not the
+//                            unknown-faction green; a swapped switch fails.
+//   - PHASE WRAPS          : FramePhase01(period, period) == 0, never 1.0 —
+//                            a missing modulo grows the ring unbounded.
+//   - TRIANGLE SYMMETRY    : PreviewRingRadius is symmetric about phase 0.5;
+//                            a sawtooth fails radius(0.3) == radius(0.7).
+//   - PEAK AT MID-CYCLE    : radius(0.5) is the widest point of the breathe.
+//   - NO NEGATIVE RADIUS   : a negative computed radius is clamped to 0 so
+//                            ImGui is never asked for a negative-radius ring.

+// swfoc_overlay/overlay_recent_actions.h — Phase 3 recent-actions history.
+//
+// The Phase 3 "Actions" widgets (Spawn / Make-Invuln / Kill, iter 520) each
+// enqueue an ActionRequest onto the ActionQueue. A recurring operator need is
+// re-firing the LAST few calls without re-typing the unit type or address —
+// the agent #2 overlay UX research flagged a "recent-actions toolbar" as a top
+// quick win (overlay_ux_research_2026-05-08.md; overlay-interactive.md line 35:
+// "re-execute last 5 SWFOC calls; ~50 LoC overlay-only; ship in Phase 3 or 4").
+//
+// RecentActions is that toolbar's backing store: a bounded, most-recent-first
+// history of dispatched ActionRequests. The render path draws one clickable
+// slot per entry; clicking a slot re-enqueues that exact ActionRequest — the
+// click-to-re-fire contract.
+//
+// Semantics are a recent-FILES list, NOT a raw FIFO ring:
+//   - Record() inserts at the front; index 0 is always the most recent.
+//   - If an entry with the SAME `lua` line already exists, it is removed from
+//     its old slot and re-inserted at the front (promote). A re-fired action
+//     therefore never duplicates a slot — the toolbar always shows up to
+//     kCapacity DISTINCT actions, which is what makes the 5 slots useful: a
+//     raw ring would show "Spawn X" five times if the operator spammed it.
+//   - The `lua` line — not the `label` — is the identity: two requests that
+//     send the identical bridge command ARE the same action even if their
+//     toast labels differ; the newer label wins on a promote.
+//   - Recording a genuinely new action when the list is full evicts the
+//     OLDEST entry (highest index). A promote never evicts (size is unchanged).
+//
+// Pure, header-only, std-only — no ImGui, no bridge, no Windows. It reuses
+// ActionRequest from overlay_action_queue.h (no new type). The whole structure
+// is unit-tested with a plain g++ — see overlay_recent_actions_test.cpp
+// (build_recent_actions_test.bat).
+//
+// THREADING: RecentActions is touched ONLY by the render thread — Record() at
+// the button / toolbar onClick site, At() / Count() while drawing the toolbar.
+// The background action worker drains the ActionQueue but never touches this
+// history. Render-thread-confined, so — unlike ActionQueue — it needs no mutex.
+//
+// WIRED (iter 521): overlay.cpp now #includes this header, owns the
+// process-wide RecentActionsInstance() function-local-static singleton, and
+// draws RenderRecentActionsToolbar() inside RenderActionsWindow. Every Phase 3
+// dispatch — button onClick or toolbar re-fire — routes through overlay.cpp's
+// DispatchAction(), which Enqueue()s the request onto the bridge worker AND
+// Record()s it here. See knowledge-base/overlay_phase3_recentactions_iter521.md.

+// RED-GREEN REGRESSION PINS
+// ------------------------
+// RecentActions has three behaviours that a naive "just push and cap" rewrite
+// would silently break:
+//   - DEDUP-PROMOTE   : recording an action whose `lua` is already present must
+//                       move that one slot to the front, not append a
+//                       duplicate. A raw FIFO ring would show the same action
+//                       in several slots. ("PIN dedup-promote".)
+//   - NO-REFIRE-EVICT : promoting an already-present action at full capacity
+//                       must NOT evict the oldest distinct action — the
+//                       promote erases one before re-inserting, so size is
+//                       unchanged. An "insert then cap" without the prior
+//                       erase would drop a real action on every re-fire.
+//                       ("PIN no-refire-evict".)
+//   - ALIAS-SAFE      : the toolbar re-fires a slot with Record(At(i)), so
+//                       `req` aliases an internal element. Record() must copy
+//                       `req` before the promote-erase or the re-insert reads

+// swfoc_overlay/overlay_spawn_gate.h — Phase 4 multi-player-safety spawn gate.
+//
+// Phase 4 (iter 292-296) lets the operator place units by drag-drop. iter-292
+// shipped the spawn pad, iter-293 the minimap, iter-294 the preview ring.
+// iter-295 (spec line 53) adds the MULTI-PLAYER SAFETY GATE: a drag-drop spawn
+// must only fire when the overlay is looking at a valid TACTICAL local player.
+//
+// SWFOC_GetLocalPlayer reports the local player's slot. In a tactical battle
+// the slot is 0..7; during a galactic-mode transition — or with no game
+// attached — the bridge cannot resolve a tactical local player and the slot is
+// -1. Spawning a unit "under" a -1 owner has no well-defined meaning (the
+// engine's Create_Generic_Object path needs a real player object), so every
+// drag-drop spawn is gated on this slot.
+//
+// The HUD worker already polls the local-player slot into
+// HudSnapshot::local_player_slot (hud_state.h). This header is the PURE
+// decision kernel layered on top of that field — the part that has a right and
+// a wrong answer and so must be pinned by a unit test before the ImGui render
+// glue in overlay.cpp (the Unit-type drag source + RenderSpawnPad +
+// RenderMinimap) depends on it:
+//
+//   1. EvaluateSpawnGate()    — classify a raw slot int into a 3-state status.
+//   2. SpawnGateAllowsSpawn() — the one boolean the drag source and the drop
+//      targets gate on.
+//   3. SpawnGateBadgeText()   — the operator-trust badge string per status;
+//      the spec requires the exact phrase "Tactical mode only" for slot -1.
+//
+// Mirrors the iter-120 LiveSkip pattern (a live-only capability is SKIPped, not
+// FAILed, when its precondition is absent) — here a drag-drop spawn is gated,
+// not errored, when there is no tactical local player.

+//                          drop always spawned) fails this pin.
+//   - VALID SLOT ALLOWED : slots 0 and 7 are Allowed — the gate must not
+//                          block legitimate tactical spawning.
+//   - BADGE PHRASE EXACT : SpawnGateBadgeText(NotInTactical) is exactly

+// swfoc_overlay/overlay_unit_aabb.h — Phase 5 unit-AABB snapshot section
+// (iter-302, spec line 60).
+//
+// Phase 5 (iter 297-303) makes the overlay click-aware. iter-298
+// (overlay_cursor_ray.h) turns a cursor pixel into a world-space pick ray;
+// iter-299 (overlay_hit_test.h) intersects that ray with a list of per-unit
+// world AABBs to find the clicked unit. Both kernels need that AABB list to
+// exist somewhere the render path can read it every frame.
+//
+// iter-302 is that storage: the UnitAabbSet — a fixed-capacity, flat-POD,
+// append-only container of per-unit world AABBs that HudSnapshot carries from
+// this iter onward (hud_state.h embeds one at the struct tail). The HUD worker
+// fills it; the render path reads it; the iter-299 raycast walks it.
+//
+// WHY A FIXED POD ARRAY, NOT std::vector
+// --------------------------------------
+// HudSnapshot is copied wholesale on every Present detour (GetHudSnapshot) and
+// rebuilt every refresh tick (hud_state.cpp). A flat POD array copies in one
+// memcpy, never heap-allocates on the render thread, and keeps HudSnapshot's
+// binary layout fixed-size — which is what the iter-275 binary-layout-stability
+// commitment wants. The capacity is kMaxRaycastUnits (64), the same
+// client-side raycast budget overlay_hit_test.h::NearestUnitHit clamps to.
+//
+// WHY APPEND-ONLY
+// ---------------
+// AppendUnitAabb only ever writes at index `count` and bumps it — entries are
+// never reordered, never removed in place. The i-th appended unit stays at
+// entries[i] for the life of the set. NearestUnitHit picks by ray-entry
+// distance, not by array index, so append order never biases the pick; but a
+// stable order means a handle that resolved to entries[i] last frame still
+// resolves there this frame unless the worker rebuilt the set. This is the
+// iter-275 stability commitment applied at the data-model level.
+//
+// This header is the pure decision kernel — the cap / validity / lookup logic
+// that has a right and a wrong answer and so must be unit-pinned before the
+// HudSnapshot field and the iter-300/301 inspector glue depend on it.
+//
+// RED-GREEN REGRESSION PINS (overlay_unit_aabb_test.cpp)
+// -----------------------------------------------------
+//   - CAP AT 64            : the 65th AppendUnitAabb returns false and leaves
+//                            count at kMaxRaycastUnits — a "no cap" old form
+//                            walks off the array end.
+//   - APPEND-ONLY ORDER    : entries[i] is the i-th unit appended — a "sort by
+//                            handle" / "reorder" old form fails.
+//   - INVALID AABB REJECTED: an inverted box (min > max) is not stored and does
+//                            not bump count — AabbIsValid screens it.
+//   - HANDLE 0 IS A MISS   : FindUnitAabb(set, 0) is always nullptr — the
+//                            engine never hands out a 0 GameObject pointer.
+//   - CLEAR RESETS         : ClearUnitAabbSet zeroes count; the next append
+//                            lands at index 0.
+//   - EMPTY SET CLEAN MISS : PickUnitInSet on the default empty set returns a
+//                            clean miss — the honest-defer state can never
+//                            produce a phantom inspector hit.
+//
+// Pure, header-only, std-only (<cstdint>, plus <cmath>/<limits> via

+// =============================================================================
+// swfoc_overlay/overlay_unit_aabb_test.cpp — unit test for overlay_unit_aabb.h
+// (Phase 5 cont., iter 302 / spec line 60).
+//
+// iter-302 is the unit-AABB storage link of Phase 5: the UnitAabbSet that
+// HudSnapshot carries so the iter-299 client-side raycast has a visible-unit
+// list to walk. overlay_unit_aabb.h holds the pure data-model logic — a
+// fixed-capacity append-only container, a 64-cap raycast budget, an inverted-
+// box screen, a handle lookup, and the PickUnitInSet seam onto NearestUnitHit.
+// This test pins all of it so the HudSnapshot field and the iter-300/301
+// inspector glue can depend on it build-only.
+//
+// The integration section runs the exact worker -> raycast pipeline: append a
+// visible-unit set the way the HUD worker will, fire a world pick ray, and
+// confirm PickUnitInSet resolves the nearest unit and FindUnitAabb recovers it
+// by handle (the iter-300 inspector resolves by handle, not by array index).
+//
+// overlay_unit_aabb.h is header-only and std-only (<cstdint>, plus
+// <cmath>/<limits> via overlay_hit_test.h). Build + run via
+// build_unit_aabb_test.bat — no game, no pipe, no ImGui.
+//
+// RED-GREEN REGRESSION PINS
+// ------------------------
+//   - CAP AT 64            : the 65th append returns false; count stays 64.
+//   - APPEND-ONLY ORDER    : entries[i] is the i-th unit appended.
+//   - INVALID AABB REJECTED: an inverted box is not stored, count unchanged.
+//   - HANDLE 0 IS A MISS   : FindUnitAabb(set, 0) is always nullptr.
+//   - CLEAR RESETS         : ClearUnitAabbSet zeroes count; next append at 0.
+//   - EMPTY SET CLEAN MISS : PickUnitInSet on the default set hits nothing.
+//   - SET FEEDS RAYCAST    : PickUnitInSet picks the same unit a hand-built
+//                            NearestUnitHit does — the iter-299/302 seam.
