From 7e6f0817956c1335a9f0ee7faf1eb9131020fe56 Mon Sep 17 00:00:00 2001 From: Dean Sharon Date: Fri, 24 Jul 2026 12:13:56 +0300 Subject: [PATCH 01/54] =?UTF-8?q?feat(external-model-routing):=20Phase=201?= =?UTF-8?q?=20=E2=80=94=20shared=20core=20+=20mapping=20engine?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements plan sections A (shared core) and B (mapping engine, TDD) for the external model routing (Devflow proxy) + per-agent model config feature. A — Shared core: - package.json: pin subswitch@0.1.0 as exact-version dependency; add Guard 3 packaging test asserting no ^/~ range prefix - src/core/external-models.ts: EXTERNAL_GPT_MODELS registry (gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna, gpt-5.5) + externalModelIds() accessor - src/core/manifest.ts: add features.proxy: boolean with self-heal absent→false, following the hud idiom; extend manifest tests for proxy field; fix init.ts manifest construction to carry proxy through re-init - src/core/proxy-state.ts: Result-typed readProxyState/writeProxyState (tolerant parse), buildRoutingConfigJson, buildProxyState, proxyBaseUrl, isProxyEnabled, resolveProxyBin (createRequire-based bin resolution, npx warning, user-facing error "routing runtime missing — reinstall devflow-kit") B — Mapping engine (TDD — tests written before implementation): - src/core/agent-frontmatter.ts: rewriteAgentFrontmatter + readFrontmatterModel, pure/zero-I/O, regex scoped to first ---…--- block, CRLF-safe EOL detection, effort add/replace/remove with double-blank-line collapse, changed: bool idempotency; 88 tests covering all 17 real agent files + synthetic cases - src/core/agent-models.ts: AgentMappingFile schema, readAgentMapping (tolerant parse, invalid effort drop+warn, unknown agents preserved), saveAgentMapping (atomic write), resolveEffective (dormancy semantics: GPT model dormant when proxy disabled, effort always applies), reapplyAgentMapping (convergence, reads shipped defaults live from src/assets/agents/), revertExternalAgents, countExternalMappedAgents; 31 tests covering schema, matrix, idempotency applies ADR-013 (new modules in src/core, agent-neutral) avoids PF-014 (Result types, no process.exit() in business logic) Co-Authored-By: Claude --- package-lock.json | 81 ++++- package.json | 3 +- src/cli/commands/init.ts | 4 +- src/core/agent-frontmatter.ts | 228 ++++++++++++++ src/core/agent-models.ts | 419 ++++++++++++++++++++++++++ src/core/external-models.ts | 36 +++ src/core/manifest.ts | 7 + src/core/proxy-state.ts | 262 ++++++++++++++++ tests/agent-frontmatter.test.ts | 363 +++++++++++++++++++++++ tests/agent-models.test.ts | 509 ++++++++++++++++++++++++++++++++ tests/manifest.test.ts | 105 ++++++- tests/packaging.test.ts | 49 +++ 12 files changed, 2062 insertions(+), 4 deletions(-) create mode 100644 src/core/agent-frontmatter.ts create mode 100644 src/core/agent-models.ts create mode 100644 src/core/external-models.ts create mode 100644 src/core/proxy-state.ts create mode 100644 tests/agent-frontmatter.test.ts create mode 100644 tests/agent-models.test.ts diff --git a/package-lock.json b/package-lock.json index 3afa97d2..679af8a7 100644 --- a/package-lock.json +++ b/package-lock.json @@ -11,7 +11,8 @@ "dependencies": { "@clack/prompts": "^0.9.1", "commander": "^12.0.0", -

unsavedCount() derived Step 9 — src/cli/agents-view/render.ts (pure frame renderer): - renderFrame(state, dims) → string[] using src/hud/colors.ts helpers - Layout: title+proxy header / column headers / scroll-up indicator / viewport rows / scroll-down indicator / unsaved count / keybinding footer - ❯ cursor marker, ‹ › active-field brackets, ● dirty markers - Dormant rows show "gpt-x.x saved" dim annotation - Proxy-off footer gains "devflow proxy --enable" hint - Narrows gracefully (truncate not wrap); never mid-row newlines Step 9 — src/cli/agents-view/terminal.ts (impure shell): - Enters alt-screen, hides cursor, setRawMode - MAX_KEYPRESSES = 50_000 hard bound (reliability rule) - Cleanup idempotent: runs on save, cancel, SIGINT, SIGTERM (avoids PF-014) - Resize re-render via stdout resize event - Returns Promise<{ action: 'save'|'cancel', state }> Step 10 — src/cli/agents-view/index.ts (barrel) Step 11 — src/cli/commands/agents.ts: - validateSetArgs() — model/effort allowlist validation (exported, testable) - applySetMapping() — immutable mapping delta (exported, testable) - buildListRows() — async list builder with installed-file probing (exported, testable) - devflow agents (bare): TUI if TTY;

Feature state is manifest-gated (like ambient/hud/rules, per ADR-001): `manifest.features.proxy` is the source of truth; `~/.devflow/proxy.json` holds runtime authority (enabled, port, binPath). `~/.devflow/proxy-routing.json` holds the routing config (port + models). The `ensure-proxy` hook (SessionStart + UserPromptSubmit, registered/removed by `addProxyHooks`/`removeProxyHooks`) auto-starts the relay and injects `ANTHROPIC_BASE_URL=http://127.0.0.1:` into `settings.json` via `applyProxyEnv`/`stripProxyEnv`. Toggle via `devflow proxy --enable/--disable/--status` or via the Advanced init wizard. Enabling runs `runProxyPreflight` (5 checks: bin, codex auth, port, settings, doctor subprocess); on failure: warning + force-disabled, init never aborted (avoids PF-009).

GPT model assignments are **dormant** when routing is off — they are stored in `agent-models.json` but not written to agent frontmatter until routing is enabled.

The redirect failure was emitted to stderr by bash itself, bypassing the 2>/dev/null that only covered wc's stderr. Result: a benign "No such file or directory" line on stderr for every first-run invocation. Fix: wrap the entire size-detection chain in [ -f "$LOG_FILE" ] so the redirect is only attempted when the file exists. Shell test added (spawnSync captures stderr for exit-0 processes): first-run with proxy enabled but no proxy.log produces empty stderr.

The feature has four layers: a **core state/mapping engine** (`src/core/`), a **proxy CLI command** (`src/cli/commands/proxy.ts`), a **per-agent TUI** (`src/cli/commands/agents.ts` + `src/cli/agents-view/`), and a **SessionStart/UserPromptSubmit hook** (`src/assets/scripts/hooks/ensure-proxy`). + +Two authority sources govern the proxy at different points in its lifecycle. `manifest.features.proxy` (manifest-group field, same as `ambient`, `hud`, `rules`) controls whether `devflow init` configures proxy-related hooks and env; `~/.devflow/proxy.json` controls whether the `ensure-proxy` hook actually activates at runtime. Both must agree for the feature to be fully operational. A drift between the two is surfaced by `devflow proxy --status`. + +## System Context + +The routing runtime is an internal package (`subswitch@0.1.0`, exact-pinned in `package.json`). Its name is a **hard branding constraint** — it must never appear in user-visible strings, error messages, CLI output, or agent context injections. User-facing vocabulary is always "external model routing" / "Devflow proxy". The one exception is internal code: health-check body comparisons (`body['name'] === 'subswitch'`), `SUBSWITCH_CONFIG` env var, and hook log lines are fine. + +## Proxy Lifecycle + +### Authority files + +| File | Role | +|------|------| +| `~/.devflow/proxy.json` | Runtime authority.

Spawn wait: 80×100ms probe loop (8s maximum, well within the hook's 15s timeout). +5. If relay never accepts: write `proxy.json` `enabled:false` (rollback), return error. +6. Settings pass: `removeProxyHooks` + `_stripProxyEnvFromObject` + `addProxyHooks` + `_applyProxyEnvToObject` — **all four calls in one atomic JSON write** to `~/.claude/settings.json`. +7.

The disable path: +1. `applyDisableToSettings(parsedSettings)` — removes hooks AND strips `ANTHROPIC_BASE_URL` (see invariant below). +2. Writes `proxy.json` `enabled:false` — **keeps** `port`, `binPath`, `configPath`, `models` for the next enable. +3. Syncs manifest to `proxy: false`. +4. `revertExternalAgents()` — rewrites installed agent files to shipped default models. +5.

The spawn lock (`$DEVFLOW_DIR/.proxy-spawn.lock`, 2s acquire timeout, 30s stale break) uses the shared `learning-lock` helper to prevent concurrent sessions from double-spawning the relay. `SUBSWITCH_CONFIG` is exported into the relay's environment before the `nohup` spawn. + +## Mapping Engine (agent-models.json) + +`~/.devflow/agent-models.json` is a **deviations-only** mapping: agents that use their shipped defaults are omitted entirely. There is **no `previousModel` field** — shipped defaults are read live from `src/assets/agents/` source files at convergence time via `loadShippedDefaults()`. + +### Dormancy semantics + +A mapping entry whose `model` is a GPT ID (in `externalModelIds()`) materializes into installed agent frontmatter **only while the proxy is enabled**. When the proxy is off, `resolveEffective()` returns the shipped default instead. The mapping entry itself is preserved on disk. + +Effort is orthogonal to dormancy — it always applies regardless of proxy state. + +```typescript +// resolveEffective — pure function, no I/O +function resolveEffective(agentName, mapping, shippedDefaults, proxyEnabled): EffectiveConfig { + const entry = mapping.agents[agentName]; + const isGpt = entry?.model !== undefined && gptIds.includes(entry.model); + + let model: string | undefined; + if (isGpt && !proxyEnabled) { + model = shippedDefaults[agentName]; // dormant — use shipped default + } else { + model = entry?.model ?? shippedDefaults[agentName]; + } + // effort always from entry regardless of proxy state: + return { model, effort: entry?.effort }; +} +``` + +### `reapplyAgentMapping` idempotent convergence + +Walks ALL installed agent files (registry names ∪ mapping keys) and calls `rewriteAgentFrontmatter()` for each. `RewriteResult.changed` is a byte-level check — files already in the desired state are untouched. Missing installed files are recorded as `skippedMissing` (not errors). Malformed frontmatter generates a warning and skips. + +**Must run AFTER preflight resolves the final `proxyEnabled` value.** In `devflow init`, the proxy preflight block can force `proxyEnabled=false` on failure. If `reapplyAgentMapping` runs before that resolution, a preflight failure leaves GPT model identifiers written into agent frontmatter files (dormancy violation — GPT lines materialize for a disabled proxy). + +## agent-frontmatter Surgical Rewrite Invariants + +`rewriteAgentFrontmatter()` in `src/core/agent-frontmatter.ts` is a pure, zero-I/O function. Key invariants that callers depend on: + +- **First-block-scoped**: the regex `FM_RE = /^---\r?\n([\s\S]*?)\r?\n---(\r?\n|$)/` matches only the first `---...---` block. A `model:` or `effort:` line in the document body is never touched. +- **CRLF-safe**: EOL style (`\r\n` or `\n`) is detected from the opening delimiter line and threaded through all replacements. Output preserves the file's original line-ending style byte-for-byte. +- **Body bytes untouched**: `afterClose` (everything after the closing `---`) is appended unchanged. +- **`RewriteResult.changed`** is a byte-level comparison (`newContent !== content`), not a semantic one. A no-op rewrite returns `changed: false` — callers use this for cheap idempotency checks. + +For error returns (`no-frontmatter`, `unterminated-frontmatter`), `reapplyAgentMapping` warns and records the agent as `skippedMissing`. + +## Agents TUI Architecture + +The TUI follows a pure-reducer / pure-renderer / thin-terminal-shell split (applies ADR-013): + +- **`state.ts`** — pure keypress reducer. `reduce(state, key) → {state, intent}`. `buildRow()` initializes dormancy state. All types and dirty helpers exported. No I/O. +- **`render.ts`** — pure renderer. `renderFrame(state, dims) → string[]`. Returns one string per terminal line with no embedded newlines. +- **`terminal.ts`** — impure shell. Manages alt-screen, raw mode, SIGINT/SIGTERM handlers, SIGWINCH resize. All cleanup wired via `resolve()` inside the Promise constructor — never `process.exit()` inside a finally-guarded scope (avoids PF-014). + +Two TUI-specific invariants: + +**`MAX_KEYPRESSES = 50_000`**: Hard upper bound on the event loop — if the TUI receives 50,000 keypresses it resolves with `action: 'cancel'`. Satisfies the project reliability rule requiring all loops to have a fixed bound. + +**`stdin.pause()` in cleanup**: The `runAgentsTui` function calls `stdin.resume()` at startup and `stdin.pause()` in cleanup. Without `stdin.pause()`, the resumed stdin TTY handle keeps the Node event loop alive after the TUI resolves, and the CLI process hangs. This is the regression guard. + +**Lazy-import of `terminal.ts`** in `agents.ts`: `import('../agents-view/terminal.js')` is deferred until the interactive path runs. `--list`, `--set`, `--reset`, and non-TTY calls never load readline/tty machinery. + +## Anti-Patterns + +- **Naming the internal routing runtime in user-visible strings**: use "external model routing" or "Devflow proxy". "subswitch" is acceptable only in code comments, logs, health-check body comparisons, and env var names. +- **Short-circuiting the disable settings pass with `||`**: `removeProxyHooks(s) || _stripProxyEnvFromObject(s)` leaves `ANTHROPIC_BASE_URL` set when hooks are present. Both operations must run unconditionally — see `applyDisableToSettings`. +- **Running `reapplyAgentMapping` before proxy preflight completes**: preflight can force `proxyEnabled=false`, and the dormancy logic depends on the final resolved value. In init, the comment at line 1344 in `init.ts` is the canonical placement anchor. +- **Calling `process.exit()` inside a finally-guarded scope in the TUI**: cleanup must be wired via Promise `resolve()`. Any `process.exit()` inside `finally` terminates without running cleanup and causes event-loop issues (avoids PF-014). +- **Using previousModel in agent-models.json**: The mapping has no `previousModel` field. Shipped defaults are always read live from `agentsDir()` source files. Caching a previousModel creates stale drift when source agent files are updated. + +## Gotchas + +- **`proxy.json` ENOENT is not an error**: `readProxyState()` returns a default disabled state when the file is missing. Callers that treat ENOENT as an error will get a false negative on fresh installs. +- **Port adoption path**: if a relay is already accepting connections on the target port and the health check confirms our identity (`name === 'subswitch'`), preflight returns `adopted: true` and `runEnable` skips spawning. The enable path then writes `proxy.json` and proceeds — the existing relay is adopted as-is. +- **`stripProxyEnv` only removes our relay's URL**: it matches `^http://127\.0\.0\.1:\d+$`. A user's own custom `ANTHROPIC_BASE_URL` (e.g., a corporate gateway) is never touched. `readProxyEnvState` distinguishes: `'ours'`, `'ours-other-port'`, `'foreign'`, `'absent'`. +- **Dormant TUI rows**: when proxy is off and an agent has a saved GPT model, `buildRow()` sets `configuredModel='default'` and stores the GPT name in `dormantModel`. On save, `applyTuiSave` checks `isDirtyModel` — if the user didn't touch the dormant row, the original GPT mapping entry is preserved byte-identical (not overwritten with 'default'). +- **`binPath` must be spawned with `node `**: npm does not guarantee executable bits on installed package binaries. Always spawn as `node `, never `` directly. +- **`resolveProxyBin()` uses `createRequire(import.meta.url)`**: ESM-safe way to resolve CommonJS package paths. The `require.resolve('subswitch/package.json')` approach finds the package relative to devflow's own `node_modules`, not the user's project. + +## Key Files + +- `src/core/proxy-state.ts` — ProxyState schema, read/write, `isProxyEnabled()`, `resolveProxyBin()`, `buildRoutingConfigJson()` +- `src/core/external-models.ts` — `EXTERNAL_GPT_MODELS` registry and `externalModelIds()` (leaf module, no project imports) +- `src/core/agent-frontmatter.ts` — pure frontmatter rewriter, `readFrontmatterModel()`, `rewriteAgentFrontmatter()` +- `src/core/agent-models.ts` — `readAgentMapping()`, `saveAgentMapping()`, `resolveEffective()`, `reapplyAgentMapping()`, `revertExternalAgents()`, `loadShippedDefaults()` +- `src/cli/commands/proxy.ts` — `proxyCommand`, `runProxyPreflight()`, `applyProxyEnv()`, `stripProxyEnv()`, `applyDisableToSettings()`, `addProxyHooks()`, `removeProxyHooks()`, `hasProxyHooks()` +- `src/cli/commands/agents.ts` — `agentsCommand`, `validateSetArgs()`, `applySetMapping()`, `buildListRows()` +- `src/cli/agents-view/state.ts` — pure reducer, `buildRow()`, `isDirtyModel()`, `isDirtyEffort()`, `unsavedCount()` +- `src/cli/agents-view/render.ts` — pure frame renderer +- `src/cli/agents-view/terminal.ts` — impure TUI shell, `runAgentsTui()` +- `src/assets/scripts/hooks/ensure-proxy` — SessionStart + UserPromptSubmit hook +- `src/cli/commands/init.ts` — proxy preflight block (lines ~1233–1360), `reapplyAgentMapping` after preflight (line ~1344) + +## Related + +- **ADR-013**: src/core vs src/cli boundary — all state I/O and pure logic in `src/core/`; CLI orchestration and user-facing action handlers in `src/cli/`.

This prevents settings.json (and any other target hardened to 0600) from being silently widened back to the umask default (~0644) on every proxy enable/disable, post-install, or init rewrite. Non-fatal path: if stat fails (ENOENT for a fresh file, or any I/O error) the chmod is skipped and the write completes normally with umask default permissions. A chmod failure also never corrupts the write (avoids PF-009 isolated-failure principle). Adds tests/fs-atomic.test.ts covering: content correctness, stale .tmp recovery, fresh-target default behavior, and the 0600/0644 mode-preservation regression (SEC-1). Mode tests are skipped on win32.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two bugs in the effort:null removal path (lines 207-224): (a) When effort: is the last frontmatter key, removing it left a stray blank line before the closing --- delimiter. The body ends with \n (the EOL preceding effort:) and reassembly prepends another \n, producing \n\n--- that no downstream collapse could catch. (b) The global /\n{2,}/g collapse (and its CRLF twin) ran over the ENTIRE frontmatter body — silently corrupting any multi-line YAML value that legitimately contains blank lines. Fix: remove exactly one adjacent EOL alongside the matched effort line. • Not the last line → swallow the trailing \r?\n after the line. • Last line → swallow the preceding \r?\n before the line. • First+only line → clear the body entirely. Drop the global collapse entirely (D-EFR-1). Regression tests (RED→GREEN verified): - effort as last key (LF): no \n\n--- in output - effort as last key (CRLF): no \r\n\r\n--- in output, no bare LF - intentional blank line inside YAML value survives byte-identically All 17 real shipped agent file cases remain green (91 total tests).

charset=UTF-8 Content-Transfer-Encoding: 8bit ARCH-1: Export buildRealPreflightDeps() factory from proxy.ts. - Consolidates realTcpConnectable / realHttpGet / realSpawnDoctor into a single reusable factory with a swallowSettingsReadError parameter that preserves the deliberate caller difference (runEnable propagates read errors; init.ts swallows to '{}' because it creates settings.json itself). - init.ts inline deps block (40 lines, byte-identical copy) replaced with buildRealPreflightDeps({settingsPath, onWarn, swallowSettingsReadError: true}). - Removes net / http / https / spawn imports that were only needed for the inline block. REL-1: Attach proc.on('error', ...) at all spawn sites. - realSpawnDoctor: error event resolves(1) + clears timer so the finally block closes logFd — prevents uncaught exception + fd leak on EMFILE/ENOMEM. - buildRealSpawnAndWaitDeps spawnProcess: error event captured via onError callback; propagated into the wait loop via spawnError flag. REL-2: Guard all unguarded writes in runEnable and runDisable. - routing-config write (fs.writeFile) and settings write (writeFileAtomicExclusive via applyEnableSettingsPass) now return errors instead of crashing with an unhandled rejection on ENOSPC/EACCES. - runDisable writeFileAtomicExclusive and writeProxyState both guarded; set process.exitCode = 1 on hard failures (avoids PF-014). - On enable failure (spawn or settings), proxy.json is rolled back to enabled:false to avoid partial-enabled state. CPLX-2: Extract spawnRelayAndWaitForPort and applyEnableSettingsPass. - spawnRelayAndWaitForPort owns spawn + adopted check + 50×100ms bounded wait + process-alive check + EADDRINUSE race detection. Accepts adopted boolean so the entire if(!adopted) branch is internalized — cleaner call site in runEnable. - applyEnableSettingsPass owns the atomic 4-call settings mutation (removeProxyHooks + stripEnv + addProxyHooks + applyEnv) plus the guarded writeFileAtomicExclusive call. - runEnable collapses from 182 lines to ~90 focused lines.

charset=UTF-8 Content-Transfer-Encoding: 8bit PERF-1: UserPromptSubmit fast exit before log setup and TCP probe — binPath/configPath reads, mkdir/stat size guard, and CWD extraction are deferred to SessionStart-only branches; the prompt hot path now exits immediately after the enabled+port check, eliminating ~5 JSON/stat subprocesses per prompt when proxy is enabled. CONS-3: source json-parse failure emits named stderr diagnostic ("ensure-proxy: failed to source json-parse") matching sibling hook pattern; exit 0 preserved (fail-open intent). CONS-4: curl health check guarded by "command -v curl >/dev/null 2>&1"; when curl is absent, the port-up path exits 0 silently ("assume ours") instead of falling through to the empty-HEALTH_BODY "*)" branch and emitting a spurious port-conflict warning. CPLX-8: log size magic numbers (_LOG_MAX_BYTES=2097152, _LOG_TAIL_BYTES=1048576) named as variables with a comment explaining why sharing hook-log-init is not feasible (that helper requires $CWD and targets the per-project log path; ensure-proxy uses the user-scope $DEVFLOW_DIR/logs path). TEST-6: adds shell-hooks.test.ts case feeding proxy.json="not-json{{{"— asserts exit 0, empty stdout, empty stderr (spawnSync, mirrors first-run stderr test pattern). CONS-4 regression test: shadow-bin approach (symlinks dirname+node into a controlled dir, omits curl, sets PATH=shadowBin:/bin) — failing before the guard, passing after.

If any of those ports happened to be transiently bound on the host, the affected test silently exercised the port-UP path instead, masking behavioral drift. Fix: add an allocateFreePort() helper that binds a net.Server on port 0, reads the OS-assigned port, closes the server, and returns the port number. Tests that need a port-DOWN scenario call await allocateFreePort() so the port is valid (OS-issued), freshly released, and overwhelmingly likely to remain free for the duration of the hook call. All 11 affected test cases converted to async and updated accordingly. No assertions changed. writeProxyJson.port made required (non-optional) to prevent future callers from relying on a hard-coded default. --- tests/shell-hooks.test.ts | 64 ++++++++++++++++++++++++--------------- 1 file changed, 40 insertions(+), 24 deletions(-) diff --git a/tests/shell-hooks.test.ts b/tests/shell-hooks.test.ts index b65c8534..df49acac 100644 --- a/tests/shell-hooks.test.ts +++ b/tests/shell-hooks.test.ts @@ -1611,14 +1611,14 @@ describe('ensure-proxy behavioral tests', () => { function writeProxyJson(opts: { enabled: boolean;

charset=UTF-8 Content-Transfer-Encoding: 8bit ARCH-2: Export isDormantGptModel(model, proxyEnabled) from external-models.ts (leaf module, no project imports — prevents import cycles with agents-view/state.ts). Replace the four duplicated dormancy predicates: resolveEffective (agent-models.ts), buildRow (state.ts), buildListRows, and the --set warning (agents.ts). Behavior identical; one authoritative site. PERF-2: Parallelize two sequential for-await loops with Promise.all. loadShippedDefaults now fans out all per-agent readFile calls concurrently (was serialized over ~34 files). reapplyAgentMapping fans out per-agent read/rewrite/write calls concurrently; results aggregated in allNamesList insertion order for deterministic warning collection and bucket assignment. Exact failure semantics preserved (ENOENT→skipped, malformed→skipped, write-error→warn+no-bucket). onWarning callback fires immediately for live feedback; the returned warnings[] is collected in stable agent-name order after Promise.all completes. TEST-7: In the two reapplyAgentMapping tests that asserted coder's shipped default ('sonnet'), replace the literal with a dynamic read via loadShippedDefaults() at describe-block init time. The same function reapplyAgentMapping calls at runtime — so the assertion now matches what the implementation writes, regardless of future model-strategy changes to coder.md.

Extract resolvePort(portOption, priorPort) — when portOption is undefined, the remembered port from proxy.json is used. Previously String(DEFAULT_PROXY_PORT) was the commander default so portOption was never undefined, making the fallback dead code: a user who enabled on port 5000, disabled, then re-enabled without --port silently reverted to 4141 (second relay spawned, old one leaked). RED-GREEN: 8 regression tests in describe('resolvePort') confirmed fail before, pass after. CONS-1: Sweep all remaining hard-failure paths in runEnable/runDisable to set process.exitCode = 1 before return — invalid port, preflight failure, malformed settings (avoids PF-014; bare return kept, never process.exit). CPLX-3: Extract resolveProcessState(featureEnabled, port) and formatProcessLine(processState, pidAlive, pidFromFile, port) from runStatus, collapsing the mirrored 3-way PID cross-check branches. Behavior/output byte-identical. CPLX-4: Name all magic timeouts and loop bounds near DEFAULT_PROXY_PORT: PROBE_TIMEOUT_MS=2000, DOCTOR_TIMEOUT_MS=10_000, RELAY_SPAWN_MAX_PROBES=50, RELAY_SPAWN_PROBE_INTERVAL_MS=100, RELAY_SPAWN_PER_PROBE_TIMEOUT_MS=500. Comment documents the intentional CLI-5s vs hook-8s budget difference. CPLX-7: Extract readPidFile(pidPath): Promise and reuse in runStatus and runDisable, replacing the duplicated read/parseInt/isNaN idiom.

Shell hook retains its own copy (different language, cannot share the TS module). CONS-5: Expand the RELAY_SPAWN_MAX_PROBES comment to explain the intentional CLI-5s vs ensure-proxy-hook-8s budget difference (interactive wait vs 15s platform-timeout revival window). Comment was terse; now self-documenting. SEC-3: Before printing the 'kill ' hint in runDisable, cross-check relay identity via realTcpConnectable + realHttpGet + isOurRelayBody. When identity is confirmed the hint is the same as before. When port is down or the health response is foreign the hint is softened ('verify before stopping manually'). Never kills programmatically. REL-3: Add SIGKILL escalation in realSpawnDoctor timeout path. After sending SIGTERM, schedule proc.kill('SIGKILL') after a 2s grace period. The escalation timer is unref()'d so it never prevents the CLI from exiting on its own. TEST-11: Add preflight test for the health-check timeout path — httpGet Err('timeout') must land in the same port-conflict Err as connection-refused.

Guard lives at init.ts call site only (shared disable/revert paths bypass it). TEST-5 (tests/init-proxy.test.ts): three integration tests driving runProxyPreflight + reapplyAgentMapping via the injectable seams to pin the dormancy ordering invariant. Correct-order tests assert that a failing preflight forces proxyEnabled=false BEFORE reapply so GPT models are suppressed; a third test documents the violation that occurs if the order is reversed. TEST-4 (tests/uninstall-logic.test.ts): temp-dir tests for removeDevFlowInstallArtifacts covering per-artifact removal (proxy.json, proxy-routing.json, proxy.pid, .proxy-spawn.lock/, logs/proxy.log), per-artifact non-fatal isolation when absent (PF-009), live-PID warning without process kill, dead-PID clean removal, and a full-pass composite. Bug found by TEST-4: { recursive: artifact.isDir } passes undefined for non-directory entries; fs.rm treats that as a type error and throws. The catch block swallowed it silently, leaving every non-directory proxy artifact in place. Fix: artifact.isDir === true (explicit boolean). avoids PF-009 (per-item failure isolation in removeDevFlowInstallArtifacts) pins ordering invariant for PF-015 (feature-toggle fan-out — GPT dormancy) Co-Authored-By: Claude --- src/cli/commands/uninstall.ts | 2 +- tests/init-proxy.test.ts | 214 ++++++++++++++++++++++++++++++++++ tests/uninstall-logic.test.ts | 118 ++++++++++++++++++- 3 files changed, 332 insertions(+), 2 deletions(-) create mode 100644 tests/init-proxy.test.ts diff --git a/src/cli/commands/uninstall.ts b/src/cli/commands/uninstall.ts index 4e99178e..c46c8d0e 100644 --- a/src/cli/commands/uninstall.ts +++ b/src/cli/commands/uninstall.ts @@ -282,7 +282,7 @@ export async function removeDevFlowInstallArtifacts(devflowDir: string, verbose: for (const artifact of proxyArtifacts) { const fullPath = path.join(devflowDir, artifact.relPath);

charset=UTF-8 Content-Transfer-Encoding: 8bit Strip resolution-pass issue-reference prefixes (ARCH-N, CPLX-N, REL-N, SEC-N, TS-N, PERF-N, Phase N) from section headers and inline comments across proxy.ts, init.ts, fs-atomic.ts — leave only the descriptive rationale. Git holds the traceability; the code should read as end-state. proxy.ts: 18 comment/header cleanups; section headers no longer encode review ticket IDs. All ADR/PF permanent doc references preserved intact. uninstall.ts: consolidate two-block proxy settings strip into a single parse-mutate-serialize pass using applyDisableToSettings (same function runDisable uses), replacing the removeProxyHooks + stripProxyEnv pair. Removes one redundant JSON round-trip; updates import accordingly. agents.ts: merge duplicate agents-view import blocks — computeViewportHeight was imported directly from render.ts while sibling exports used index.js; now all agents-view imports flow through the barrel. terminal.ts: remove comment explaining that FIXED_ROWS comes from render.ts (visible from the import; comment described the refactoring, not the state). --- src/cli/agents-view/terminal.ts | 2 -- src/cli/commands/agents.ts | 2 +- src/cli/commands/init.ts | 16 +++++------ src/cli/commands/proxy.ts | 50 ++++++++++++++++----------------- src/cli/commands/uninstall.ts | 13 ++++----- src/core/fs-atomic.ts | 2 +- 6 files changed, 38 insertions(+), 47 deletions(-) diff --git a/src/cli/agents-view/terminal.ts b/src/cli/agents-view/terminal.ts index 73c84ea2..b77383c2 100644 --- a/src/cli/agents-view/terminal.ts +++ b/src/cli/agents-view/terminal.ts @@ -24,8 +24,6 @@ import type { AgentsViewState } from './state.js'; /** Hard upper bound on keypress events — resolves with 'cancel' on exhaustion. */ export const MAX_KEYPRESSES = 50_000; -// FIXED_ROWS and computeViewportHeight imported from render.ts (single source of truth). - // --------------------------------------------------------------------------- // Terminal escape sequences // --------------------------------------------------------------------------- diff --git a/src/cli/commands/agents.ts b/src/cli/commands/agents.ts index 7d91a5b1..0635c7ba 100644 --- a/src/cli/commands/agents.ts +++ b/src/cli/commands/agents.ts @@ -40,10 +40,10 @@ import { } from '../../targets/claude-code/claude-paths.js'; import { buildRow, + computeViewportHeight, type AgentsViewState, type AgentRow, } from '../agents-view/index.js'; -import { computeViewportHeight } from '../agents-view/render.js'; // --------------------------------------------------------------------------- // Result type (local pattern) diff --git a/src/cli/commands/init.ts b/src/cli/commands/init.ts index 320e86a5..64b76071 100644 --- a/src/cli/commands/init.ts +++ b/src/cli/commands/init.ts @@ -1251,11 +1251,9 @@ export const initCommand = new Command('init') } if (routingConfigWritten) { - // ARCH-1: consume shared factory — removes 40-line inline copy that duplicated - // proxy.ts implementations byte-identically.

Key invariants that callers depend on: +`rewriteAgentFrontmatter()` in `src/core/agent-frontmatter.ts` is a pure, zero-I/O function. Key invariants: -- **First-block-scoped**: the regex `FM_RE = /^---\r?\n([\s\S]*?)\r?\n---(\r?\n|$)/` matches only the first `---...---` block. A `model:` or `effort:` line in the document body is never touched. -- **CRLF-safe**: EOL style (`\r\n` or `\n`) is detected from the opening delimiter line and threaded through all replacements. Output preserves the file's original line-ending style byte-for-byte. +- **First-block-scoped**: `FM_RE = /^---\r?\n([\s\S]*?)\r?\n---(\r?\n|$)/` matches only the first `---...---` block. A `model:` or `effort:` line in the document body is never touched. +- **CRLF-safe**: EOL style (`\r\n` or `\n`) is detected from the opening delimiter line and threaded through all replacements. - **Body bytes untouched**: `afterClose` (everything after the closing `---`) is appended unchanged. -- **`RewriteResult.changed`** is a byte-level comparison (`newContent !== content`), not a semantic one. A no-op rewrite returns `changed: false` — callers use this for cheap idempotency checks. +- **`RewriteResult.changed`** is a byte-level comparison (`newContent !== content`), not a semantic one. -For error returns (`no-frontmatter`, `unterminated-frontmatter`), `reapplyAgentMapping` warns and records the agent as `skippedMissing`. +**D-EFR-1: Surgical effort-line removal** (`effort: null`): removes only the matched effort line plus exactly one adjacent EOL — no global `\n{2,}` collapse. The adjacent EOL consumed depends on position: +- effort is last line → swallow the preceding `\r?\n` (no trailing EOL in fmBody) +- effort is mid-body → swallow the trailing `\r?\n` after the line +- effort is first and only line → clear fmBody to `''` + +This prevents silent corruption of multi-line YAML values that legitimately contain blank lines. ## Agents TUI Architecture The TUI follows a pure-reducer / pure-renderer / thin-terminal-shell split (applies ADR-013): -- **`state.ts`** — pure keypress reducer. `reduce(state, key) → {state, intent}`. `buildRow()` initializes dormancy state. All types and dirty helpers exported. No I/O. -- **`render.ts`** — pure renderer. `renderFrame(state, dims) → string[]`. Returns one string per terminal line with no embedded newlines. +- **`state.ts`** — pure keypress reducer. `reduce(state, key) → {state, intent}`. `buildRow()` calls `isDormantGptModel()` (from external-models) to initialize dormancy state. All types and dirty helpers exported. No I/O. +- **`render.ts`** — pure renderer. `renderFrame(state, dims) → string[]`. Exports `FIXED_ROWS` and `computeViewportHeight` — consumed by `terminal.ts` (single source of truth for viewport constants). - **`terminal.ts`** — impure shell. Manages alt-screen, raw mode, SIGINT/SIGTERM handlers, SIGWINCH resize. All cleanup wired via `resolve()` inside the Promise constructor — never `process.exit()` inside a finally-guarded scope (avoids PF-014). -Two TUI-specific invariants: +**`TuiIO` injectable seam** (`terminal.ts`): `runAgentsTui(initialState, io?)` accepts an optional `TuiIO` override with fake `stdin`/`stdout` for testing. The default is `process.stdin`/`process.stdout`. Tests pass `PassThrough` streams to drive the TUI without a real TTY. + +**`MAX_KEYPRESSES = 50_000`**: Exported constant — hard upper bound on the event loop. Resolves with `action: 'cancel'` on exhaustion. Tests pin this value directly (agents-terminal.test.ts). -**`MAX_KEYPRESSES = 50_000`**: Hard upper bound on the event loop — if the TUI receives 50,000 keypresses it resolves with `action: 'cancel'`. Satisfies the project reliability rule requiring all loops to have a fixed bound. +**`stdin.pause()` in cleanup**: `runAgentsTui` calls `stdin.resume()` at startup and `stdin.pause()` in cleanup. Without `stdin.pause()`, the resumed stdin TTY handle keeps the Node event loop alive after the TUI resolves and the CLI hangs. -**`stdin.pause()` in cleanup**: The `runAgentsTui` function calls `stdin.resume()` at startup and `stdin.pause()` in cleanup. Without `stdin.pause()`, the resumed stdin TTY handle keeps the Node event loop alive after the TUI resolves, and the CLI process hangs. This is the regression guard. +**`FIXED_ROWS`/`computeViewportHeight` single-sourced from `render.ts`**: `terminal.ts` imports both from render.ts — no duplication. **Lazy-import of `terminal.ts`** in `agents.ts`: `import('../agents-view/terminal.js')` is deferred until the interactive path runs. `--list`, `--set`, `--reset`, and non-TTY calls never load readline/tty machinery. +## writeFileAtomicExclusive — Mode Preservation + +`writeFileAtomicExclusive` (in `src/core/fs-atomic.ts`) now preserves the target file's permission mode across atomic replace: + +1. Write to `.tmp` with O_EXCL (crash-safe). +2. `stat(filePath)` to read the existing mode (permission bits only, masked with `0o777`). +3. `chmod(tmp, mode)` — best-effort, non-fatal on ENOENT (fresh file) or any other error. +4. `rename(tmp, filePath)` — POSIX atomic. + +A user who hardened `settings.json` to `0600` (to protect `ANTHROPIC_API_KEY`) no longer has it silently widened to the umask default on every proxy enable/disable. The chmod step is non-fatal (avoids PF-009) — write correctness is never sacrificed for mode preservation. + ## Anti-Patterns - **Naming the internal routing runtime in user-visible strings**: use "external model routing" or "Devflow proxy". "subswitch" is acceptable only in code comments, logs, health-check body comparisons, and env var names. -- **Short-circuiting the disable settings pass with `||`**: `removeProxyHooks(s) || _stripProxyEnvFromObject(s)` leaves `ANTHROPIC_BASE_URL` set when hooks are present. Both operations must run unconditionally — see `applyDisableToSettings`. -- **Running `reapplyAgentMapping` before proxy preflight completes**: preflight can force `proxyEnabled=false`, and the dormancy logic depends on the final resolved value. In init, the comment at line 1344 in `init.ts` is the canonical placement anchor. +- **Short-circuiting the disable settings pass with `||`**: `removeProxyHooks(s) || _stripProxyEnvFromObject(s, port)` leaves `ANTHROPIC_BASE_URL` set when hooks are present. Both operations must run unconditionally — see `applyDisableToSettings`. +- **Running `reapplyAgentMapping` before proxy preflight completes**: preflight can force `proxyEnabled=false`, and the dormancy logic depends on the final resolved value. In init, the guard is placed immediately after the proxy preflight block. - **Calling `process.exit()` inside a finally-guarded scope in the TUI**: cleanup must be wired via Promise `resolve()`. Any `process.exit()` inside `finally` terminates without running cleanup and causes event-loop issues (avoids PF-014). - **Using previousModel in agent-models.json**: The mapping has no `previousModel` field. Shipped defaults are always read live from `agentsDir()` source files. Caching a previousModel creates stale drift when source agent files are updated. +- **Duplicating the dormancy predicate**: `isDormantGptModel(model, proxyEnabled)` from `external-models.ts` is the single source of truth. Do not inline `externalModelIds().includes(model) && !proxyEnabled` at call sites. ## Gotchas - **`proxy.json` ENOENT is not an error**: `readProxyState()` returns a default disabled state when the file is missing. Callers that treat ENOENT as an error will get a false negative on fresh installs. -- **Port adoption path**: if a relay is already accepting connections on the target port and the health check confirms our identity (`name === 'subswitch'`), preflight returns `adopted: true` and `runEnable` skips spawning. The enable path then writes `proxy.json` and proceeds — the existing relay is adopted as-is. -- **`stripProxyEnv` only removes our relay's URL**: it matches `^http://127\.0\.0\.1:\d+$`. A user's own custom `ANTHROPIC_BASE_URL` (e.g., a corporate gateway) is never touched. `readProxyEnvState` distinguishes: `'ours'`, `'ours-other-port'`, `'foreign'`, `'absent'`. -- **Dormant TUI rows**: when proxy is off and an agent has a saved GPT model, `buildRow()` sets `configuredModel='default'` and stores the GPT name in `dormantModel`. On save, `applyTuiSave` checks `isDirtyModel` — if the user didn't touch the dormant row, the original GPT mapping entry is preserved byte-identical (not overwritten with 'default'). +- **Port adoption path**: if a relay is already accepting connections on the target port and the health check confirms our identity (`name === 'subswitch'`), preflight returns `adopted: true` and `spawnRelayAndWaitForPort` skips spawning. +- **`stripProxyEnv` is port-scoped (REG-1)**: `stripProxyEnv(settingsJson, managedPort)` removes `ANTHROPIC_BASE_URL` **only when its value exactly matches `http://127.0.0.1:`**. A localhost URL on any other port classifies as `'ours-other-port'` or `'foreign'` and is never touched. Callers must pass the port Devflow owns (from `proxy.json.port` or `DEFAULT_PROXY_PORT`). `readProxyEnvState` uses the pattern `^http://127\.0\.0\.1:\d+$` to classify any localhost URL as `'ours-other-port'` for display purposes only — the strip never uses that broad pattern. +- **Remembered port on re-enable**: `--port` has no commander default. When `--port` is omitted, `portOption` is `undefined` and `resolvePort(undefined, priorPort)` returns the remembered port from `proxy.json`. Prior to this fix, the commander default of `String(DEFAULT_PROXY_PORT)` made the remembered port dead code. +- **Dormant TUI rows**: when proxy is off and an agent has a saved GPT model, `buildRow()` calls `isDormantGptModel()` and sets `configuredModel='default'` with the GPT name in `dormantModel`. On save, if `isDirtyModel` is false, the original GPT mapping entry is preserved byte-identical. - **`binPath` must be spawned with `node `**: npm does not guarantee executable bits on installed package binaries. Always spawn as `node `, never `` directly. - **`resolveProxyBin()` uses `createRequire(import.meta.url)`**: ESM-safe way to resolve CommonJS package paths. The `require.resolve('subswitch/package.json')` approach finds the package relative to devflow's own `node_modules`, not the user's project. ## Key Files - `src/core/proxy-state.ts` — ProxyState schema, read/write, `isProxyEnabled()`, `resolveProxyBin()`, `buildRoutingConfigJson()` -- `src/core/external-models.ts` — `EXTERNAL_GPT_MODELS` registry and `externalModelIds()` (leaf module, no project imports) +- `src/core/external-models.ts` — `EXTERNAL_GPT_MODELS` registry, `externalModelIds()`, `isDormantGptModel()` (leaf module, no project imports) - `src/core/agent-frontmatter.ts` — pure frontmatter rewriter, `readFrontmatterModel()`, `rewriteAgentFrontmatter()` - `src/core/agent-models.ts` — `readAgentMapping()`, `saveAgentMapping()`, `resolveEffective()`, `reapplyAgentMapping()`, `revertExternalAgents()`, `loadShippedDefaults()` -- `src/cli/commands/proxy.ts` — `proxyCommand`, `runProxyPreflight()`, `applyProxyEnv()`, `stripProxyEnv()`, `applyDisableToSettings()`, `addProxyHooks()`, `removeProxyHooks()`, `hasProxyHooks()` +- `src/core/fs-atomic.ts` — `writeFileAtomicExclusive()` — mode-preserving atomic write +- `src/cli/commands/proxy.ts` — `proxyCommand`; exported seams: `buildRealPreflightDeps`, `spawnRelayAndWaitForPort`, `resolvePort`, `isOurRelayBody`, `runProxyPreflight`, `applyProxyEnv`, `stripProxyEnv`, `applyDisableToSettings`, `addProxyHooks`, `removeProxyHooks`, `hasProxyHooks`, `readProxyEnvState` - `src/cli/commands/agents.ts` — `agentsCommand`, `validateSetArgs()`, `applySetMapping()`, `buildListRows()` - `src/cli/agents-view/state.ts` — pure reducer, `buildRow()`, `isDirtyModel()`, `isDirtyEffort()`, `unsavedCount()` -- `src/cli/agents-view/render.ts` — pure frame renderer -- `src/cli/agents-view/terminal.ts` — impure TUI shell, `runAgentsTui()` +- `src/cli/agents-view/render.ts` — pure frame renderer; exports `FIXED_ROWS`, `computeViewportHeight` +- `src/cli/agents-view/terminal.ts` — impure TUI shell, `runAgentsTui()`, `TuiIO`, `MAX_KEYPRESSES` - `src/assets/scripts/hooks/ensure-proxy` — SessionStart + UserPromptSubmit hook -- `src/cli/commands/init.ts` — proxy preflight block (lines ~1233–1360), `reapplyAgentMapping` after preflight (line ~1344) +- `src/cli/commands/init.ts` — proxy preflight block; `reapplyAgentMapping` guard after preflight ## Related - **ADR-013**: src/core vs src/cli boundary — all state I/O and pure logic in `src/core/`; CLI orchestration and user-facing action handlers in `src/cli/`.

A pre-spawn gate is always unsatisfiable on a cold path: the port is down by definition before spawn, so doctor exits 1 every time, blocking enable even when all prerequisites (bin, codex auth, free port, clean settings) are healthy. Fix: move doctor from runProxyPreflight (check ⑤) to a new runPostSpawnVerification step that runs after spawnRelayAndWaitForPort confirms the port is up. Doctor now sees "running: YES" on the healthy path, fulfilling its actual role (validate codex auth + TLS reachability against a live relay). Kill-on-rollback when doctor fails is restricted to self-spawned relays: adopted relays may be serving other live sessions and must not be killed. spawnedPid is now returned from SpawnRelayResult so the caller knows whether this enable originated the relay. init.ts is unchanged in behaviour — it only runs checks ①–④ via runProxyPreflight and lets ensure-proxy start the relay at next session. Tests: preflight suite asserts spawnDoctor is never called; new runPostSpawnVerification suite covers the four ordering cases (doctor called, zero→Ok, non-zero+self-spawned→rollback+kill, non-zero+ adopted→rollback without kill); proxy-enable suite covers spawnedPid in the result. --- src/cli/commands/proxy.ts | 160 +++++++++++++++++++++++++++++++------ tests/init-proxy.test.ts | 6 +- tests/proxy-enable.test.ts | 20 +++++ tests/proxy.test.ts | 109 +++++++++++++++++++++---- 4 files changed, 255 insertions(+), 40 deletions(-) diff --git a/src/cli/commands/proxy.ts b/src/cli/commands/proxy.ts index cb70093b..aea318fb 100644 --- a/src/cli/commands/proxy.ts +++ b/src/cli/commands/proxy.ts @@ -360,7 +360,11 @@ export interface PreflightResult { * ② ~/.codex/auth.json exists. * ③ Port probe: free → OK; accepting → health check → adopt or fail. * ④ settings.json parseable; ANTHROPIC_BASE_URL not pointing elsewhere; API key warn. - * ⑤ Doctor: `node doctor` with SUBSWITCH_CONFIG env, 10s cap. + * + * Doctor (previously check ⑤) is deliberately excluded: the relay's doctor subcommand + * probes the relay port — a not-yet-started relay makes that probe fail (exit 1).

Called pre-spawn in `runEnable` (Step 2, before `spawnRelayAndWaitForPort`) so no live relay fd can be orphaned by the rename. Constants (2MB/1MB) match ensure-proxy. - `ensure-proxy` rotation tmp created under `umask 077` subshell for the same reason. **Tests (14 new):** - `tests/proxy-log.test.ts`: openProxyLog fresh+pre-existing, chmod-failure non-fatal, buildChildEnv strips key, rotateProxyLogIfLarge size+mode+tail-content assertions.

charset=UTF-8 Content-Transfer-Encoding: 8bit - git mv src/hud/cache.ts src/core/cache.ts; update sole consumer (version-badge.ts) to pass ctx.devflowDir-derived cacheDir and a typed validator function. Removes getCacheDir() which duplicated and diverged from getDevFlowDirectory(). - writeCache becomes async (writeFileAtomicExclusive is async; no sync variant exists). version-badge.ts now awaits the write. - Validate on read: readCache/readCacheStale accept a validator function called on every read; no more blind JSON.parse-as-T cast. Validates envelope structure (finite timestamp/ttl), future-timestamp rejection, MAX_TTL_MS clamping, and data schema via the injected validator. - Path containment: safeEntryPath() rejects any key component that resolves outside cacheDir — an unvalidated key is an arbitrary-file-overwrite primitive via path.join normalization. - Permissions: mkdir at 0700, entries at 0600 (mirrors proxy-log.ts). - PID-scope the atomic tmp name in fs-atomic.ts (${filePath}.tmp.PID) to prevent concurrent-process tmp collisions (applies PF-011). Mirror the same naming in json-helper.cjs and decisions-usage-scan.cjs (per the comment at fs-atomic.ts:10-13). Update fs-atomic and json-helper-write-exclusive tests to use PID-scoped paths.

Includes 'fable': devflow's set is a superset of the routing runtime's passthrough regex so fable is never misclassified as external (T9). - Add isClaudeModelName() — pure complement predicate. Returns true for aliases, 'inherit', and any 'claude-' prefixed name. - Add isDormantExternalModel() — single dormancy export (AC-C6). Classification is by the complement: external iff not Claude and not 'default'. Supersedes isDormantGptModel() (alias-shaped non-Claude names are now dormant-when-off; documented in commit body). - Convert all four recognition-set consumers to isDormantExternalModel: src/core/agent-models.ts:resolveEffective src/core/agent-models.ts:countExternalMappedAgents (was inlining externalModelIds() set — live correctness bug: proxy --status showed "0 external agents" for alias-shaped mappings) src/cli/agents-view/state.ts:buildRow src/cli/commands/agents.ts:buildListRows + --set warning - Move CLAUDE_MODEL_ALIASES import at five call sites (state.ts, agents.ts, agents-state.test.ts, agent-models.test.ts, agents-command.test.ts) from agent-models to external-models. - Remove dead isProxyEnabled import from agent-models.ts (ADR-003). - T9 and countExternalMappedAgents complement-predicate tests in tests/external-models.test.ts. Documented behaviour change: a hand-edited non-Claude model name (not just a known GPT ID) is now dormant-when-off. Not self-healing — the value is preserved on-disk until --set, TUI save, proxy toggle, or init.

A newline-embedded payload (e.g. "gpt-4\ntools:\n - bash") would inject arbitrary YAML keys. Fix: export MODEL_NAME_RE and isValidModelName; return Err('invalid-model') before any string replacement when the name fails the regex. The same regex is exported for reuse at the discovery boundary in a later phase. S2 (HIGH — pre-existing): stripAnsi matched only SGR sequences (\x1b\[[0-9;]*m).

Verified by whole-dist grep of the routing runtime 0.2.0 package: it reads exactly three env vars (ANTHROPIC_API_KEY, FORCE_COLOR, SUBSWITCH_CONFIG). An allowlist is the correct shape — 61 vars → 5. Call sites in proxy.ts compose on top of scrubChildEnv() rather than the function taking parameters: relay spawn: { ...scrubChildEnv(), SUBSWITCH_CONFIG: configPath } doctor spawn: { ...scrubChildEnv(), SUBSWITCH_CONFIG: configPath } Also strips the tombstone comment in external-models.ts that narrated the removed isDormantGptModel behaviour change (applies ADR-003). Test T11 (AC-S3): exact-key-set assertions across scrubChildEnv() and both spawn-path compositions; poisoned env includes ANTHROPIC_API_KEY, OPENAI_API_KEY, SSH_AUTH_SOCK, and two additional credential vars.

Add offCyclePin to AgentRow for retired-model cycle reachability (AC-F4). Show alias resolution in render: "sol (gpt-5.6-sol)" for aliases, bare for canonical IDs (AC-F2). Show "(unavailable)" for off-cycle pins. TUI path: start discoverExternalModels without awaiting, with 250ms spinner threshold. --set path: cache-only via getExternalModelsCached (0 spawns, AC-P9). --list, --reset: never discover. Tests: remove externalModelIds() references from agents-command, agents- state, init-proxy tests; replace with literal list (ADR-003 prep for registry deletion). Add T8, AC-F1 through AC-F5, AC-P6 tests in agents-state. Update agents-render helpers to include catalog/modelCycle.

When the relay returns fields in a different order (e.g. {"version":"0.2.0","providers":[...],"name":"subswitch"}) the pattern fails to match, causing the hook to emit a false "port occupied by another application" warning even when the relay is legitimately ours. Fix: replace the substring case-match with a json_field "name" "" call that parses the body key-order-independently via jq or node. json_field is already sourced (json-parse, line 32) and is always available at the health-check call site because line 33 exits if _JSON_AVAILABLE=false.

--set calls getExternalModelsCached (sync, zero spawns); --list/--reset/--status never touch discovery - Replace all isDormantGptModel() references with isDormantExternalModel() - Fix Key Files entry for external-models.ts: CLAUDE_MODEL_ALIASES, isClaudeModelName(), isDormantExternalModel() (was stale deleted symbols) - Add anti-pattern D-EFR-3: mock-only subprocess tests must be paired with a CI-executed real-binary test; documents tests/integration/ CI-exclusion trap (PF-016 reproduced) - Add gotcha: leaked stub relays must be reaped on the failure path too - Add cache details: version key format, 0700/0600 permissions, stale fallback by embedded timestamp, 3-entry prune, resolveProxyBin() version validation (RUNTIME_VERSION_RE);
