Problem

PostHog Code today is a list-of-tasks UI for orchestrating cloud agents. The "Barbados hackathon" team (Schmidt, Aly, Sean, Steven, Brooker) built an RTS-style alternative — instead of a queue, you place "nests" (goal containers) on a 2D map and watch "hoglets" (agent runtimes) work the goal, with a hedgehog acting as the orchestrator. Internal codenames during development were "Hedgemony" and briefly "Hogcraft"; the official name landing here is PostHog Code RTS mode / code-rts.

It's hokey on purpose, but it surfaces orchestration state in a way the list view can't (idle vs working hoglets, PR dependency graph, FinOps cost overlay, signal ingestion). Goal of this PR: land what we have as the v1 surface so we can iterate stacked PRs on top. No expansion of scope beyond what shipped at the hackathon demo.

Changes

High-level

  • New feature behind RTS_FLAG (rts-enabled PostHog feature flag). Off by default; toggle on the user/account for opt-in.
  • New tRPC namespace rts.* under apps/code/src/main/trpc/routers/rts.ts, backed by ~10 main-process services in apps/code/src/main/services/rts/.
  • Renderer feature at apps/code/src/renderer/features/rts/ (map view, sprites, dialogs, audio).
  • DB additions consolidated into a single new migration 0006_rts_schema.sql (Schmidt flattened the per-slice chain — see his commit message for the rationale).

Static assets — hosted externally, not bundled

918 short voice mp3s (3 fun modes × 2 genders × ~50 lines × 3 takes) plus a BGM track are served from Stephen's Cloudflare R2 bucket ph-code-rts, fronted by code-rts.posthog.com:

  • Default base: https://code-rts.posthog.com/static/code-rts/
  • Overridable per-build via VITE_CODE_RTS_ASSETS_BASE_URL
  • Bundle impact: 0 MB (would have been ~7 MB if bundled)

Voice lines were generated via ElevenLabs Multilingual v2 (mp3_22050_32) under PostHog's ElevenCreative Starter commercial license. Voice IDs documented at the CDN in CREDITS.md. The generator script lives at scripts/generate-voice.mjs and re-runs idempotently against notes/rts/voice-lines.json.

Sub-features

  • Nests + Hoglets: place a nest on the map, give it a goal prompt and definition-of-done, spawn hoglets to work the goal. Hoglets are agent runs (existing PostHog Code task infrastructure) attached to a nest.
  • Hedgehog orchestrator: tick-based loop that perceives hoglet state every turn (terminal output + tool calls), can hold/inject/decompose/dismiss/spawn-follow-up. Signal ingestion (cloud SignalReports → hedgehog nudges) is an explicit operator opt-in.
  • PR graph: per-nest visualization of PR dependency edges; right-pane editor for follow-up linkage.
  • FinOps panel: raw API cost overlay (per-nest, per-hoglet, per-workload). Gated behind RTS_FINOPS_FLAG (rts-finops-enabled) and an @posthog.com email check — figures are raw cost, not consumer pricing.
  • Fun modes: none / pirate / lolcat voice line variants for the hoglets, per-gender.
  • Audio: BGM during map view, throttled voice lines on hoglet events, sfx via WebAudio.

Feature flags involved

Flag Default Purpose
rts-enabled off Master gate for RTS mode UI
rts-finops-enabled off FinOps panel + money-hog sprite (also @posthog.com-gated in code)

Both flags created in PostHog admin (US project 2).

How did you test this?

  • Typecheck: clean (pnpm --filter code typecheck).
  • Unit tests: 1715 of 1734 pass locally. The 19 failing tests are all in usage-event-repository.test.ts / operator-decision-repository.test.ts and fail with better-sqlite3 NODE_MODULE_VERSION mismatch (compiled against Electron NAN 145, tests need Node NAN 127). Environment-only — CI runs against clean Node so these will pass there. No code-level regressions.
  • Manual: demoed end-to-end at the Barbados hackathon (place nest, spawn hoglets, watch tick loop, validate goal completion, voice + BGM playing, FinOps overlay rendering raw cost) — see #hackathon-hedgemony channel for video clips.

History: this branch has 270+ commits. Plan to squash-and-merge so main gets one clean commit.

Publish to changelog?

No — feature is off behind a flag and we'll publish to changelog when we promote to a default-on / GA experience in a follow-up PR.

Rework the map input model around standard RTS conventions:

- Left-click selects a nest or the builder hedgehog (selection ring).
- Right-click on empty map issues a move command for the selected
  unit, with an animated slide and a destination ripple marker.
- Esc clears selection or cancels build mode.

Add a persistent builder hedgehog unit as the only entry point for
creating nests. Selecting it opens a docked command panel; clicking
"Build nest" enters build mode (crosshair cursor, dashed ghost circle
following the pointer, top banner). Clicking ground places the nest;
right-click or Esc cancels.

Drag-to-move sprites is removed entirely; positioning happens via
command issuance, not direct manipulation.

Vendor the hedgehog-mode sprite atlas (sprites.png + sprites.json,
MIT) and add a tiny AnimatedHedgehog component that drives frames via
a requestAnimationFrame ticker (handles multi-row animations the way
CSS steps() cannot).

The builder runs a state machine of idle / walking / building. Right-
click move plays walk facing the move direction; on arrival it returns
to idle. After PlaceNestDialog submits, the builder walks to the new
nest coords and plays the action animation for 1.5s.

Reconcile the docs with what's in code (commits 25503fd, cab2fba,
c1a23ab) and where Slice 1 is heading.

Three creation surfaces coexist deliberately:
- Builder → Build nest: guided GoalSpecDraftService conversational flow.
- Builder → Quick nest: one-field form, minimal nest, auto-spawns first
  hoglet in the same transaction.
- Wild hoglet: dedicated toolbar/keyboard action, NOT in BuilderCommandPanel.
  Genuine one-offs that don't deserve a nest record.

- spec.md: Builder added to vocabulary; "Ad-hoc and wild" rewritten;
  new "Map controls (RTS conventions)" section.
- user-stories.md: Slice 0 mentions persistent Builder + RTS controls;
  Slice 1 reframed as "Builder two-button split" with creation_mode
  column and atomic Quick-path first-hoglet spawn; Slice 2 clarifies
  wild entry is distinct from Builder.
- backend-frontend.md: new "Builder unit + map controls" section above
  the prickle section, with the right-click-only rationale.

Surfaces the guided vs simple paths upfront on BuilderCommandPanel
instead of burying them behind a toggle inside PlaceNestDialog.

- BuilderCommandPanel: adds onQuickNest callback, renders a second
  button (Lightning icon) next to "Build nest" (Plus icon). Each
  button has a tooltip describing what its path does.
- PlaceNestDialog: accepts initialMode?: "guided" | "simple" and
  uses it to preset the existing simpleMode state on open. Defaults
  to "guided" so existing callers are unchanged. The in-dialog
  Eject/Switch-back toggle still works after entry.
- HedgemonyMapView: tracks pendingMode (defaults to "guided"). Build
  nest sets it to "guided" before entering build mode; Quick nest
  sets it to "simple". On placement, the dialog opens with the
  matching initial mode.

Quick-path's atomic first-hoglet spawn isn't wired yet — that's
backend work for Slice 1. This commit lands only the upfront UI
split so the path is visible to operators.

The builder hedgehog used to walk in a straight line and run through
nest sprites, and the build-flow walk landed it on top of the new
nest. Replace the single-target spring tween in BuilderSprite with a
multi-waypoint walker, and route every walk through a grid A* search
with string-pulled output and destination snap-to-obstacle-edge.

- Guided nest creation now conducts a short conversational loop
  through GoalSpecDraftService before the operator edits the final
  spec. The service prompts the LLM gateway for clarifying questions
  and, once context is sufficient, returns an editable draft with
  name, goal, and definition-of-done pre-filled.
- A single-turn safety net forces at least one clarification when
  the operator's initial prompt is short or under-specified, even
  if the LLM jumps straight to a proposed spec.
- The creation transcript (operator messages + draft responses) is
  persisted alongside the nest chat audit record so the reasoning
  behind a nest's goal is traceable after the fact.
- NestService now strips transient creation fields before passing
  input to the repository, keeping the DB insert clean.
- PlaceNestDialog is restructured: GoalDraftFlow handles the
  conversational loop, SpecFields the editable result, and
  SimpleFormFields the eject path. Map coordinates are editable
  and validated before submission.
Replace the tron-style dot grid and crossed laser bars with scattered
green hedge patches, a soft meadow wash, and faint topographical
contour rings. Soften zone outlines to dashed surveyor borders.

Remove the dashed yellow command-path lines drawn on move/relocate/
build — the destination pulse ring is enough feedback.

…ding

Two bugs were stacking on top of each other:

1. findPath snapped goals radially out of obstacles via pushOutOf, so a
   click that landed inside a nest's inflated radius ended up on a random
   side instead of where the builder was heading. The move marker still
   flashed at the raw click, so the visual lied. Replace with snapGoal
   that walks from `to` toward `from` and returns the first unblocked
   point — destination lands on the perimeter facing the approach.

2. startWalk used builderPath[lastReachedIndex] (last waypoint reached)
   as `from`. Mid-walk the sprite is between waypoints, so Framer Motion
   animated straight from its current screen position to path[1] — a
   segment the planner never verified clear. Builder visually cut through
   buildings. BuilderSprite now writes its live motionX/motionY into a
   MutableRefObject the view reads at re-plan time.

Also: flash the move marker at the resolved goal (not the raw click) so
feedback matches reality.

Replace the framer-motion spring on NestSprite with imperative animate()
+ useMotionValue (mirrors BuilderSprite), so travel time is proportional
to distance with a smooth ease-in-out and no overshoot. Swap the static
builder-hog image for AnimatedHedgehog playing the walk cycle while in
flight (facing flips on dx) and idle when stopped.

Add a "Movement feel" subsection under Map controls noting the two rules
that make unit motion read as RTS: constant world-space speed (so duration
scales with distance — no position-keyed springs) and a smooth ease with
no overshoot. Record current per-unit speeds, ease curves, and the
walk-anim + facing-flip requirement so future units inherit the feel.

Replace CSS-gradient backdrop with a single SVG that ships hand-coded
prop sprites (oak, pine, bush, flowering bush, boulder, boulder cluster,
stump, wildflower, mushroom) plus turbulence-based terrain mottling and
a fine grass-noise tile. Props are deterministically scattered (seeded
RNG, biased per zone, y-sorted for painter-algorithm depth) and avoid
nest rings and the map center.

Drop the dashed rounded-rect zone containers in favor of soft tinted
ellipse blobs with crisp DOM-rendered topographic labels.

Replaces the placeholder builder-hog-in-a-ring with a dedicated nest
illustration. The building is its own asset; the hedgehog is composited
on top at the entrance only when the nest is non-dormant, so empty/quiet
nests read differently from active ones at a glance.

GoalSpecDraftService now returns a structured feature specification
instead of a flat goalPrompt string. The app renders the accepted
spec as editable Markdown with user stories, requirements, and
success criteria — giving the hedgehog a richer anchor for later
planning and completion judgment.

- Goal drafts produce structured fields (summary, primaryScenario,
  userStories with acceptance scenarios, requirements with FR-IDs,
  keyEntities, assumptions, successCriteria with SC-IDs, and
  definitionOfDone). The service assembles these into a rendered
  goalPrompt Markdown so the operator can review and edit before
  creating the nest.
- Single-turn under-specification guard still forces at least one
  clarifying question before proposing a spec from a short prompt.
- Nest creation audit records now include the planning method tag
  and label the persisted goal as "Spec" instead of "Goal" so the
  trail reflects the structured origin.
- PlaceNestDialog relabels the goal field as "Spec", increases the
  textarea to 10 rows for the longer rendered output, and updates
  transcript formatting to show the summary separately.
- spec-driven-development planning method is defined as a shared
  constant and inlined into the LLM system prompt so the gateway
  call applies it without a skill loader.
- Flood-filled the white background out of nest.png so it composites
  cleanly on the forest map.
- While the nest is in flight, fade the building out and scale the
  resident hedgehog up to ~88px centered, playing its walk cycle.
  When stopped, the hedgehog shrinks back to the doorway (44px @ 72%)
  and the building reappears. Restores the "hedgehog is the mover"
  read that the RTS-movement commit was going for.

The dialog used to upsert the created nest into the local store on
submit, so the sprite appeared the instant the form closed — before
the builder walked anywhere. Path planning then ran against the
already-rendered nest, and because the visual nest radius exceeds the
collision radius, the hedgehog could end up overlapping it.

Now the dialog hands the full nest to HedgemonyMapView via onCreated,
which parks it in a local pendingBuild state. The location is added
to the obstacle list during pathfinding (so the builder snaps to the
perimeter) but the sprite isn't committed to the store until the
build animation completes. Interrupts (right-click to move, starting
another build) commit the pending nest first so it always ends up
visible.

…rd math

- New useBuilderCoordinator hook owns path, walking/building/idle state,
  build timer, and the visualPosRef. View consumes builder.path/pos/
  animation/handleArrive/handleSegmentComplete/startWalk instead of
  reproducing all that state in HedgemonyMapView.
- Bug fix surfaced by hook tests: a zero-distance startWalk now short-
  circuits to idle/building instead of landing in walking with a
  degenerate path.
- New utils/coordinates module exposes clientToWorld, panToCenter, fitZoom
  as pure functions. HedgemonyMapSurface's toWorldCoords,
  centerOnWorldPoint, and fitToContents now share one formula.
- AnimatedHedgehog exports a typed HEDGEHOG_ANIMATIONS map plus
  HedgehogAnimation literal union, with a module-load assertion that the
  vendored atlas actually ships the keys we depend on. Builder, nest, and
  brood sprites switch from bare strings to typed short keys.
- Tests for the hook (10 cases) and coordinate utils (8 cases).

Adds five test cases for the onPendingBuildCommit + buildingFor flow
that landed on top of the coordinator extraction:

- commits the pending nest after build animation completes
- commits early when a non-build walk interrupts mid-flight
- handleArrive + timer firing only commits once (no double-fire)
- queueing a second pending build commits the first immediately
- no commit when no pending build was queued

…y button

When the LLM gateway returns non-JSON content (prose, refusals, fences), the
goal-drafting flow used to dead-end with a raw "Goal draft response was not
valid JSON" error inside the nest builder dialog. Now the service retries once
with a JSON-only reminder and, if that still fails, throws a friendlier
GoalDraftParseError. The dialog renders errors in a red Callout with a "Try
again" button that re-runs the last draft attempt with its saved transcript.

Replaces the parallel buildMode/relocatingNestId/pendingMode booleans in
HedgemonyMapView with a single discriminated union:

  type ViewMode =
    | { kind: "browsing" }
    | { kind: "placingNest"; creationMode: NestCreationMode }
    | { kind: "relocatingNest"; nestId: string };

Each interaction handler (handleMapClick, handleMapRightClick, ESC) now
switches on mode.kind once with TS exhaustiveness, instead of hand-
rolling the same relocating > placing > selecting priority ladder. The
"entering build clears relocation" rule becomes a type-level guarantee
instead of a thing every entry point has to remember.

Selection stays orthogonal to mode (persists across transitions).
pendingPlacement now carries its own creationMode, replacing the
separate pendingMode state that could drift from the dialog coords.

The HedgemonyMapSurface props are unchanged — buildMode and
relocatingNestId are derived from mode at the call site.

- When the hedgehog's `message_hoglet` falls through to the suppress
  branch (running hoglet whose task tab is not attached in the
  renderer), the chat audit now tells the operator exactly what
  happened and what to do: "could not deliver: the hoglet's task tab
  is not currently open. Open the hoglet to deliver the message, or
  wait for the run to complete." Non-hedgehog failed routes
  (pr_review / ci with no nest) keep their existing "no active
  session, no nest; logged only" wording.
- The hedgehog's Operational Posture gains an explicit recovery
  path for these audits: it must not blindly re-probe — it waits
  for operator attachment, waits for the run to complete (where
  findings surface as a hoglet_summary row), or, for genuinely
  time-sensitive questions, calls write_audit_entry to escalate to
  the operator in nest chat.
- The hedgehog now treats the goal prompt's User Stories section as
  its natural decomposition unit: default one hoglet per P1 story
  or per cluster of 2-3 tightly-related stories. A single
  end-to-end hoglet is appropriate only when the nest has 1-2 user
  stories or the work fits in <30 minutes of cloud time. Coupling
  between hoglets is managed via link_pr_dependency (genuine PR
  stacking) or by sequencing (foundational hoglet first, then
  parallel-spawn the rest) — coupling-by-fusion is explicitly the
  wrong reflex.
- NestService.create synthesizes a `## Summary` + `## User Stories`
  section onto goal prompts that lack one. Quick-mode nests
  (operator submits a one-line goal without going through the
  draft chat) now have structure for the decomposition rule to
  anchor against, and the hedgehog's behavior stays consistent
  across nest creation modes.
- notes/hedgemony/hedgehog-direct-injection.md documents the
  proper longer-term fix for the delivery gap: main-side direct
  injection to the cloud task, removing the renderer from the
  hedgehog → hoglet path entirely so operator attachment is purely
  about observation. Includes open questions to resolve with the
  cloud team. Today's audit copy is the stopgap that makes the
  current failure mode legible while that work is scoped.
- The hedgehog can now reach an in_progress hoglet whose task tab
  the operator has never opened. message_hoglet no longer routes
  through the renderer's SDK socket — main POSTs a JSON-RPC
  user_message command directly to the cloud run's existing
  /command/ endpoint via CloudTaskClient.injectPrompt, using the
  same auth plumbing as other cloud-task calls. Operator attachment
  collapses back to pure observation; the autonomous orchestration
  loop no longer depends on which tabs are open.
- FeedbackRoutingService.routeHedgehogPrompt picks one of three
  paths off (latestRunId, targetRunStatus): direct-inject when the
  target is in_progress with a known run id, emit a follow-up
  fallback event when the target is terminal (completed / failed /
  cancelled), record failed for everything else (queued,
  not_started, unknown). Pending-row reservation happens before
  any awaited cloud call so a concurrent tick can't double-emit
  while the POST is in flight.
- When injectPrompt returns run_unavailable — the most likely
  reason being that the tick's latestRunId is stale — recovery
  re-fetches the latest run and either retries once against the
  fresh in-progress id or emits a follow-up fallback if the
  current run is terminal. Single-shot, no recursion, so a cloud
  that keeps returning run_unavailable can't loop. The same
  recovery is invoked when the hedgehog claimed in_progress but
  carried no latestRunId at all.
- The audit copy and the hedgehog's Operational Posture clause now
  describe failures as "cloud run not currently accepting
  messages" rather than "task tab not open", matching the new
  delivery model. Hedgehog-source injected outcomes are labelled
  "delivered to cloud run" to distinguish them from operator-side
  "injected into live session".
- resolveHedgemonyPromptRoute short-circuits hedgehog source past
  the inject path: it only returns spawn_follow_up (with nest) or
  failed. useHedgemonyPromptRouter loses the
  suppress_hedgehog_follow_up branch and the hogletStore lookup
  for latestRunStatus — the renderer no longer participates in
  hedgehog delivery decisions, only in spawning follow-ups for
  terminal-run fallbacks.
- messageHogletHandler awaits the routing call and passes the
  freshest latestRunId from the tick context, so the scratchpad
  summary reflects the actual outcome of the route rather than a
  hopeful "injected" label. Per-tick latency now scales with
  message_hoglet count, which is bounded by the hedgehog's own
  probe discipline.
- Provenance is conveyed in the prompt body prefix ("Message from
  the Hedgemony hedgehog orchestrating this nest:") because the
  cloud-side stores user_message commands as user-authored.
  First-class authored_by metadata is left as a future backend
  improvement; the prefix keeps attached renderer sessions from
  reading hedgehog probes as operator messages.
- New tests cover: direct inject of an in_progress run, retry
  against a fresh latestRunId on run_unavailable, follow-up
  fallback when recovery discovers a terminal run, rejected
  responses recording failed without re-fetching, and terminal
  targets emitting the renderer fallback. The renderer routing
  test drops the suppress branch and pins the new hedgehog →
  spawn_follow_up / failed contract.
- The hedgehog can now deliberately wait via a `hold` tool when no
  productive state-change or query-state action is available this
  tick. A hold writes one detail-visibility audit row (not summary),
  suppresses the hedgehog's free-text reasoning from recent_chat,
  and persists an activeHold on the nest state. Subsequent ticks
  short-circuit before invoking the model until the next trigger
  fires (operator_response, hoglet_output, pr_status_change, or
  timeout), so a held nest no longer manufactures probes and audits
  every minute to satisfy the every-tick-must-act constraint.
- injectPrompt now returns a `processed` state alongside `accepted`:
  "active" when the cloud runtime consumed the message during its
  current turn, "queued" when it was enqueued for the next turn
  boundary, "unknown" when the cloud endpoint does not yet surface
  this distinction (default until cloud-side support lands). The
  routed-feedback audit reads "delivered to cloud run (queued; will
  be read at next turn boundary)" instead of letting the operator
  believe the probe landed during a 30-minute implementation pass.
- Each per-hoglet prompt block now includes a pending_injections
  field counting hedgehog injections whose processed state is
  queued/unknown and which haven't been answered by a newer
  last_output_at. The system prompt forbids sending another
  message_hoglet when this count reaches 2, so prior probes stop
  stacking up unread mid-turn.
- A nest-level lockstep_silence anomaly surfaces when 2+ hoglets
  spawned within 5 minutes of each other have all been quiet for
  30+ minutes. The prompt clause treats coordinated multi-hoglet
  silence as evidence of infra trouble (queue saturation, auth
  blip, runtime error) and asks for a single nest-level audit
  plus a hold, rather than three independent "probably fine"
  rationalizations.
- Two prompt-only Operational Posture clauses: downstream hoglets
  stacked on a parent branch can make progress independently of
  whether the parent PR has merged, so parent merges are not
  progress bottlenecks; and an operator request escalated twice
  without response is not escalated a third time — surface once
  via write_audit_entry, hold on operator_response, stop.
- Migration adds a `processed` column (default "unknown") to
  hedgemony_feedback_event so the field survives process restarts.
- Operator chat releases any active hold regardless of its
  nextTrigger. Operator interruption beats whatever the hedgehog
  chose to wait for, so a wedged nest can always be unstuck by
  asking a question.
- Every hold now carries a timeoutAt — either the explicit
  timeoutSeconds the hedgehog supplied, or a 1-hour dispatcher
  fallback. Event-trigger holds whose signal never arrives can
  no longer become permanent.
- Hedgehog can now perceive hoglet output without the renderer
  being attached. The main-side poll reads /session_logs/, finds
  the run's terminal turn_complete:end_turn boundary, and writes
  the assistant text as a tool_result row from main. The
  renderer-side mirror becomes a latency optimization rather
  than a correctness dependency.
- tool_result and hoglet_summary appends now enqueue a hedgehog
  tick. Previously the new hoglet_output hold trigger depended
  on out-of-band enqueueTick calls from whoever wrote the row;
  the dispatcher itself now closes the loop.
- Failed and cancelled runs surface a chat summary too —
  "Run failed: <error_message>" or "Run cancelled." — so nest
  chat tells the full lifecycle instead of silently dropping
  non-completed terminations.
- Cloud-log perception trusts turn_complete:end_turn as the
  deliverable signal and skips the text-shape heuristic that
  previously gated final-output detection. The heuristic
  survives only on the chat-message inference path where no
  explicit turn boundary exists.
- Renderer final-output producer subscribes to the hoglet store
  in addition to the session store, so it re-fires when the
  hoglet roster shows up after the session has already
  completed.
- Hedgehog now reads one nest message per Claude API turn from cloud
  session logs (new `hoglet_message` kind), so mid-run probe replies
  and intermediate progress reach perception without the operator
  opening a task tab. Replaces the brittle "most recent turn_complete
  must be end_turn" extractor that left the hedgehog blind for any
  hoglet still in an active tool-use loop.
- Turn boundaries are detected from `_posthog/turn_complete`
  notifications and deduped by `(taskId, runId, turnIndex)`. Cloud
  session logs strip `agent_message_chunk` server-side, so the
  extractor handles only whole `agent_message` events.
- Renderer-side perception producer, the duplicate extractor utility,
  the `recordHogletFinalOutput` tRPC route and service/repo methods,
  and the `looksLikeDeliverable` text heuristic are all removed.
  There is one perception path now: main-side poll → per-turn rows.
- `HOGLET_OUTPUT_KINDS` becomes the single source of truth for which
  kinds count as hoglet output; tick-service consumes the set
  directly instead of string-matching message kinds.
- Spawn-hoglet prompt cap raised 8k → 32k with handler-side
  truncation, so the hedgehog can issue richer decomposition prompts
  without zod rejecting oversized inputs. The spawn audit records
  whether truncation happened and the original length.
- `write_audit_entry` accepts structured `summary`/`detail` args by
  JSON-stringifying objects/arrays, so the LLM no longer trips a
  validation error by passing a non-string value.
- Hold release watches a `(latestRunId, taskRunStatus,
  latestRunCompletedAt, prUrl, prState, branch)` fingerprint and
  fires when the cloud run state changes, so a hoglet completing or
  opening a PR unwedges the nest without waiting for chat output.
  Branch-PR fallback queries GitHub by `head:owner:branch` when
  the cloud run's `output.pr_url` lags behind the actual open PR.
- `pending_injections` no longer counts `processed: "unknown"`
  injections as stacked, eliminating a false-lockstep classification
  that came from cloud command responses that can't yet report
  processing state.
- Event-hold fallback timeout shortened from 60 min to 10 min;
  fingerprint-based release is now the primary signal, with the
  timeout acting as a dead-man's switch.
- The hedgehog no longer drops tool calls when the model emits a
  structured object or array for a prose argument. The textArg
  preprocessor (JSON-stringify non-string inputs before string
  validation) previously protected only `write_audit_entry`; it
  now applies to every prose-bearing arg on every hedgehog tool:
  `spawn_hoglet.prompt`, `message_hoglet.prompt`,
  `raise_hoglet.prompt`, `kill_hoglet.reason`, `hold.reason`,
  `mark_validated.summary`, `link_pr_dependency.reason`,
  `unlink_pr_dependency.reason`, `rebase_child.prompt`,
  `request_repository_access.reason`. Observed in a live nest: the
  model emitted two `spawn_hoglet` blocks per tick when reasoning
  was bloated, one with a flat string prompt and one with a
  partial-object prompt; the latter rejected and the planned hoglet
  silently disappeared until the hedgehog re-planned.
- `message_hoglet.prompt` cap raised 2_000 → 8_000 chars. It was
  the hedgehog's only runtime H→h send channel and the narrowest
  prose cap by 4×, which forced terse course-corrections and left
  no headroom for substantive context-passing. 8_000 matches
  `write_audit_entry.detail`, the next-closest "the hedgehog said
  something substantive" tier.
- Identifier fields (`hoglet_id`, `edge_id`, `parent_task_id`,
  `child_task_id`, `signal_report_id`, `repository`, the array
  members on `mark_validated`) keep raw `z.string()` — those
  should fail fast on type errors, not coerce away mistakes.
- Per-tool magic-number caps replaced with named
  `MAX_*_CHARS` constants exported from `hedgehog-tools.ts`, so
  the size policy is grep-able in one place and the two-layer
  spawn cap (`MAX_SPAWN_HOGLET_TOOL_INPUT_CHARS` wide on the LLM
  side, `MAX_SPAWN_HOGLET_PROMPT_CHARS` strict at the handler) is
  visibly the only asymmetric one.
Concrete substage breakdown, import-rewrite estimates, risk list, and
recommendation. Doc that gates the launch of Stage 5.

Voice lines and background music now stream from
https://posthog.com/hogcraft/ instead of being bundled into the
Electron app. Drops the production bundle size by ~6.5 MB and removes
918 tracked wav binaries from the repo.

- voice.ts reads a static voice-manifest.json and prefixes each entry
  with VOICE_BASE_URL (overridable via VITE_HOGCRAFT_VOICE_BASE_URL).
- BgmPlayer.tsx points at the CDN bgm URL
  (overridable via VITE_HOGCRAFT_BGM_URL).
- generate-voice.mjs now outputs mp3_22050_32 directly (no more
  PCM→WAV header dance) and writes voice-manifest.json after each run.
- voice-lines.json updated with new voice IDs from PostHog's
  ElevenCreative account (Liam, Laura, Callum, Lily — default library
  voices matching the existing archetype hints).
- .gitignore excludes the local voice/ output dir so future runs don't
  accidentally re-commit binaries.

The audio itself is hosted via a separate PR on posthog.com under
static/hogcraft/{voice/,bgm.mp3} with attribution + a robots.txt
disallow.

Matches the official feature name "PostHog Code RTS mode". The flag

Renames the four hedgemony directories (renderer feature, main service,
asset images, notes) to rts/ and updates all import path references.
Identifier renames (HedgemonyController, hedgemonyStore, etc.) follow
in a separate commit.

…rts*

Files-only rename within the already-moved rts/ directories (DB migration
filenames and assets/sounds/hedgemony-bgm.mp3 left untouched — migrations
are tombstones, bgm is moving to CDN separately). Internal identifier
renames (types, vars) follow next.

…Rts*/rts*

Sweeps PascalCase types (HedgemonyEvent → RtsEvent) and camelCase
identifiers (hedgemonyNests → rtsNests, hedgemonyRouter → rtsRouter,
etc.) across the codebase.

Deliberately left alone:
- SQL table/index names ("hedgemony_nest", etc.) — migration tombstones
- The "hedgemony-enabled" feature flag string value — coordinate
  PostHog admin rename separately
- The trpc namespace mount key ("hedgemony: rtsRouter") — follow-up
  commit will rename that + downstream client refs

…a attrs

Renames remaining hedgemony references:
- trpc namespace mount: `hedgemony: rtsRouter` → `rts: rtsRouter`,
  plus all `trpcClient.hedgemony.*` / `trpc.hedgemony.*` / `trpcReact.hedgemony.*`
  call sites updated to `.rts.`
- Zustand persistence keys ("hedgemony-view-storage", "hedgemony-hoglet-positions")
  and localStorage key ("hedgemony-nest-draft") renamed to "rts-*"
- HTML data attribute `data-hedgemony-nest` → `data-rts-nest`
- ShortcutCategory enum and object literal keys renamed to "rts"

Existing-user impact: the persistence-key rename means anyone who had
Zustand state or the nest draft cached under the old keys will see a
reset on first launch. Acceptable for a feature still in hackathon scope.

…ys, prose

Final sweep of remaining hedgemony refs after the structural renames:
- Logger scope strings ("hedgemony-voice" → "rts-voice", etc.)
- Analytics event names (HEDGEMONY_HOGLET_SPAWNED → RTS_HOGLET_SPAWNED,
  "hedgemony.hoglet_spawned" → "rts.hoglet_spawned")
- React component keys ("hedgemony-fullscreen", "hedgemony-hotkey-helper")
- sfxStore Zustand persistence key ("hedgemony-sfx-storage" → "rts-sfx-storage")
- Stale tRPC namespace ref in MarkValidatedDialog comment
- Prose in code comments and aria-labels

Still deliberately kept:
- "hedgemony-enabled" feature flag string (PostHog admin rename separate)
- SQL table/index names in db/schema.ts and db/migrations/ (tombstones)
- assets/sounds/hedgemony-bgm.mp3 file path (audio dir cleanup separate)

Last sweep — remaining hedgemony references that needed targeted edits:
- bgmStore Zustand persistence key ("hedgemony-bgm-storage" → "rts-bgm-storage")
- Remaining logger scopes ("hedgemony-cloud-task-client", "hedgemony-usage-pricing", "hedgemony-schemas")
- Worktree bootstrap branch prefix (`hedgemony-bootstrap-` → `rts-bootstrap-`)
- Hedgehog-id and task-branch prefixes in test fixtures
- Test fixture object keys mocking the tRPC namespace ({ hedgemony: ... } → { rts: ... })
- captureException property name (hedgemony_signal_trigger → rts_signal_trigger)

What's still labelled "hedgemony" by design:
- SQL table/index names in db/schema.ts and db/migrations/ (migration tombstones)
- "hedgemony-enabled" feature flag string in shared/constants.ts (PostHog admin rename separate)
- Code comments that accurately describe SQL table names (e.g. "writes the local hedgemony_hoglet sidecar")
- apps/code/src/renderer/assets/sounds/hedgemony-bgm.mp3 (audio dir cleanup separate)

- Hedgemony's drizzle migration chain (0006_hedgemony_nest through
  0018_feedback_processed) is collapsed into a single
  0006_rts_schema.sql. The pre-flatten journal was already
  inconsistent — entries 0011–0018 had no snapshot JSON — so any
  future db:generate would have produced garbage diffs.
  Post-flatten, db:generate diffs cleanly against 0005_snapshot.
- SQL identifiers finish the Hedgemony→Rts rename: every
  hedgemony_* table and index is now rts_* (rts_nest, rts_hoglet,
  rts_nest_message, rts_hedgehog_state, rts_feedback_event,
  rts_pr_dependency, rts_operator_decision, rts_usage_event,
  rts_tick_log). The TypeScript identifiers (rtsNests, etc.) were
  already renamed; the SQL names had been left as tombstones to
  avoid migration churn, which the flatten makes free.
- The PostHog feature-flag key "hedgemony-enabled" is now
  "rts-enabled". RTS_FLAG was already the in-repo constant name;
  only the string value lagged. The cloud-side flag rename lands
  separately — until it does, anyone who had the old flag toggled
  on will see the renderer gates (CommandCenterView,
  CommandCenterToolbar, BgmPlayer) flip off.
- Remaining hedgemony strings outside the table-name strings are
  cleaned up: tsdoc comments naming SQL tables, one debug log, a
  raw-SQL test fixture, a test description, and the design notes
  under notes/rts/*.

Existing-DB impact: the flatten emits plain CREATE TABLE
statements, so a dev DB that already has 0006–0018 applied will
fail with "no such table: rts_hoglet" because drizzle sees nothing
newer to apply. Delete the dev DB once before launching:

rm "$HOME/Library/Application Support/@posthog/posthog-code-dev/posthog-code.db"*
BgmPlayer fetches from the CDN now (https://posthog.com/code-rts/bgm.mp3
by default, overridable via VITE_CODE_RTS_BGM_URL), so the local mp3
is dead code.

Adds a dedicated feature flag for the FinOps surface in addition to
the existing @posthog.com email gate. Lets us toggle the dialog +
toolbar chip + money-hog sprite off centrally without code changes
if we ever need to (e.g. while iterating on the cost figures).

- New flag: `rts-finops-enabled` (boolean)
- Dev default: on (via import.meta.env.DEV) so the team still sees it locally
- Production default: off until the flag is created + toggled in PostHog admin

Behavior:
- Non-PostHog accounts: still hidden (email gate unchanged)
- PostHog accounts with flag off: hidden
- PostHog accounts with flag on: visible (today's behavior)

- Signal ingestion no longer starts implicitly on map mount.
  rtsSignalIngestionEnabled persists in electron-store and
  defaults to false: launching the app never silently begins
  spawning hoglets from cloud SignalReports, which removes a
  class of runaway-spawn risk on top of the existing
  nest-hoglet cap.
- A new toolbar control ("Signals on/off") flips the persisted
  preference and starts or stops the poll loop in one round
  trip. The mutation is optimistic with rollback-on-error so
  the button feels instantaneous, and it is the only callsite
  that toggles persisted state — cancel() still exists for the
  test-only path that stops the loop without persisting.
- Mid-flight disable is honored: isEnabled() is rechecked at
  every async seam in the poll path (before listSignalReports,
  before each batch iteration, before each ingestOne, after
  fetching artefacts). A toggle-off lands at most one report
  late, and only if its spawn had already committed.
- Once spawnSignalBacked commits, the HogletIngested emit is
  intentionally not gated — committing a hoglet to the DB
  without firing the UI/analytics event would leave the
  operator with no breadcrumb for the spawn. A regression test
  pins this invariant.
- The tRPC surface gains rts.signalIngestion.status and
  rts.signalIngestion.setEnabled and drops the now-redundant
  isRunning query; status returns {enabled, running} which
  subsumes the old endpoint.
Consolidates the per-asset URL/env vars into a single shared base:

- New `CODE_RTS_ASSETS_BASE_URL` in shared/constants:
  `https://code-rts.posthog.com/static/code-rts`
  (served from Stephen's Cloudflare R2 bucket `ph-code-rts`)
- One env override `VITE_CODE_RTS_ASSETS_BASE_URL` instead of the
  previous two (`VITE_CODE_RTS_VOICE_BASE_URL`, `VITE_CODE_RTS_BGM_URL`)
- voice.ts and BgmPlayer.tsx both build their URL off the shared base

The posthog.com static hosting plan got dropped in favor of R2 — see
the #hackathon-hedgemony thread starting 2026-05-20.

Two small leaks/silent failures the adversarial review caught:

- The Audio element created on mount was never released. Mount/unmount
  cycles (StrictMode, route changes) accumulated orphaned audio
  elements. Cleanup pauses, clears src, and nulls the ref so the
  next mount creates a fresh element.
- `audio.play().catch(() => {})` silently swallowed autoplay-policy
  rejections and network errors, leaving users with no debug path.
  Now logs via `logger.scope("rts-bgm")` like the rest of the audio
  module.

Moves files that were RTS-feature-specific out of shared directories
into dedicated `rts/` subdirs, so the boundary between core
PostHog Code and the (opt-in, feature-flagged) RTS mode is clearer.

- `apps/code/src/main/db/repositories/{nest,hoglet,hedgehog-state,
  nest-message,feedback-event,operator-decision,pr-dependency,
  tick-log,usage-event}-repository.{ts,mock.ts,test.ts}` → `db/repositories/rts/`
- `scripts/generate-voice.mjs` → `scripts/rts/generate-voice.mjs`
  (REPO_ROOT path adjusted for the new depth)
- All imports updated; no behavior change.

Also cleans up `.claude/stock-research/agent-usage.json` (leftover
Claude-Code agent-telemetry from the hackathon) and adds the
directory to `.gitignore`.

Replace eight `as unknown as` (and one `as StoredLogEntry[]`) casts in
`apps/code/src/main/services/rts/cloud-task-client.ts` with Zod schemas
that fully describe the cloud API response shapes for Task, TaskRun,
SignalReport, SignalReportArtefact* variants, and stored session log
entries. Each schema is pinned to its shared TS type via
`satisfies z.ZodType<...>` so any future drift between the renderer
shape and the cloud shape fails the build, not the call site.

The schemas live in a new `cloud-task-schemas.ts` alongside the client.
Required fields are required so malformed cloud responses throw a
`CloudApiResponseError` immediately, rather than producing a partial
object whose missing fields fail later (and farther from the cause).
Existing pr_url and branch validations are preserved.

Test fixtures grew `taskFixture()` and `taskRunFixture()` helpers so
the three mocks that previously relied on cast-driven leniency now
return shapes that match what production cloud returns.

Covers the handler files under apps/code/src/main/services/rts/hedgehog-handlers/
that previously had no colocated tests. Each test exercises happy path,
input-validation rejection, and at least one error/edge case using mocked
service dependencies (no DB, no electron).

Handlers covered:
- kill-hoglet (happy path, hoglet-not-in-nest, inactive skip, missing run id,
  cloud-task error)
- spawn-hoglet (primary-repo resolution, per-tick cap, unavailable repo,
  no-repo-resolvable, spawn failure)
- raise-hoglet (happy path, in-progress skip, rollback on start failure,
  per-tick cap, hoglet-not-in-nest)
- message-hoglet (route + audit, hoglet-not-in-nest, non-routable status
  passes targetRunStatus=null)
- link-pr-dependency (link + audit, same-task rejection, missing task,
  pr-graph error)
- unlink-pr-dependency (unlink + audit, missing edge, pr-graph error)
- rebase-child (rebase + audit, missing edge, pr-graph error)
- mark-validated (service call + stopDispatch, validation error,
  service error)
- request-repository-access (granted, denied, resolver error, validation)
- write-audit-entry (summary only, summary + detail, validation error)

Adds a shared test-helpers.ts with fixture builders for Nest, Hoglet,
HogletWithState, OperatorDecision, PrDependency, TickContext, and a mock
HedgehogToolDeps factory.

NestDetailPanel was 974 lines with 22 useState hooks mixing chat, PR graph,
hoglet roster, validation, and metadata edit concerns into one render. Pulled
each seam into its own file under nest-detail/ so the parent panel becomes a
thin orchestrator (974 -> 221 LOC).

New files under apps/code/src/renderer/features/rts/components/nest-detail/:

- NestDetailHeader.tsx: console header, hedgehog ticking badge, relocate button
- NestMetadataFields.tsx + useNestMetadataEdit.ts: name / goal / definition-of-done
  fields with save-to-tRPC + per-field state owned by the hook
- ValidationBanner.tsx: validating / validated lifecycle banners
- HogletsSection.tsx: hoglet roster + HogletCard with release/retire dialogs
- PrGraphSection.tsx: PR dependency graph rows, edge unlink, state badge
- NestChatMessages.tsx + NestChatMessage.tsx: chat history list, scroll-to-bottom,
  and feedback / pr-graph routed message variants
- NestChatComposer.tsx + useNestChat.ts: chat composer state + send mutation
- NestDetailFooter.tsx: save / compact / archive footer buttons
- LabeledField.tsx: shared label wrapper

No behavior change: same JSX tree, same hotkeys (s / a / r), same dialogs,
same scroll-on-open behavior. The parent NestDetailPanel keeps shared
lifecycle derivation, archive handler, hotkeys, and the validation /
compact dialogs.

Splits the 1255-line hedgehog-tick-service.ts into three files, each with a
single responsibility:

* `hedgehog-tick-service.ts` (1045 LOC) — keeps the tick scheduler and
  perception orchestrator. Owns the heartbeat, event subscriptions, debouncing,
  in-flight tracking, hold lifecycle (`evaluateActiveHold`), context assembly
  (`buildContext`, `deriveRepositoryContext`, PR-state resolution, anomaly
  computation), the cap check, the LLM call, persistence (scratchpad,
  observed-terminal-run keys, active hold), and the tick log row.

* `hedgehog-decision-router.ts` (266 LOC, new) — owns handler dispatch and
  feedback correlation. Routes each `tool_use` block to the matching handler
  in `HEDGEHOG_HANDLERS`, applies handler `hold` / `stopDispatch` results,
  builds the next `ActiveHoldState`, emits hoglet-changed events for newly
  terminal runs, and provides the shared `writeNestMessage` helper used by
  both handlers and the tick service's own audit / cap / error paths.

* `hedgehog-tick-helpers.ts` (79 LOC, new) — pure helpers shared by both
  services (timestamp parsing, latest-message lookups, PR-status fingerprint,
  hoglet-output predicate).

Wired through DI: new `MAIN_TOKENS.HedgehogDecisionRouter` token, bound in
`container.ts`, injected into `HedgehogTickService`. The tick service
delegates to `decisionRouter.dispatch(...)`, `emitNewTerminalHogletChanges`,
and `writeNestMessage`.

No behavior change. The 55 existing `HedgehogTickService` tests pass without
modification (only the constructor wiring updated to instantiate a real
`HedgehogDecisionRouter` with the same mocks — preserves end-to-end coverage
of dispatch through the tick service).

Two pre-merge cleanups from the reviewer-persona pass:

- AppLifecycleService.doShutdown() now explicitly calls .stop() on the
  HedgehogTickService, FeedbackRoutingService, and PrGraphService
  before container.unbindAll(). Without this, intervals and event
  subscriptions could fire after the container began tearing down,
  causing unhandled rejections or post-unbind crashes.
- The three services' start() calls in main/index.ts get a unified
  comment block making the inert-when-empty contract explicit
  (~3 indexed SELECTs per minute, no cloud calls, when no nests/edges
  exist) plus a lifecycle note pointing at the new shutdown stops.
- shared/constants.ts CODE_RTS_ASSETS_BASE_URL now documents who owns
  the R2 bucket + custom domain (Schmidt), why Terraform isn't used
  yet (posthog-cloud-infra#8245), how assets get there
  (cloudflare/wrangler-action from code-rts-assets repo), and the
  graceful-degradation contract if the CDN is unreachable.
