taodengandClaude Opus 4.7 994568a8fb feat+ci: D38 — maxConcurrent runtime enforcement (issue #1)
ADR 0002 Amendment 1 declared `hints.maxConcurrent` declarative-only at
v0.1 — type-validated at startup but with no runtime enforcement.
D38 wires the runtime enforcement via a per-provider in-flight spawn
counter with immediate-advancement on saturation.

Design choice: **immediate-advancement via fallback engine** (queue +
timeout DEFERRED). When a provider is at its maxConcurrent limit, the
spawn call synchronously fails with a new `CONCURRENCY_LIMIT` error
code; the fallback engine treats this as a hard trigger and advances
to the next chain hop. If the entire chain is saturated, the user
sees a chain-exhausted error (existing path).

Rationale for immediate-advancement over queue+timeout:

1. The fallback chain exists precisely for this kind of overflow —
   adding a queue layer would duplicate the advancement semantics.
2. Queue + timeout adds new config surface (timeout duration, queue
   depth bounds, queue eviction policy) that isn't needed at the
   personal/family scale OLP serves.
3. Head-of-line blocking risk: a long-running spawn would stall
   queued requests behind it even though other providers in the chain
   could serve them immediately.
4. Fail-fast latency aligns with the multi-provider proxy philosophy
   ("spread risk across providers, not within a provider").

Queue + timeout is deferred to a v1.x design ADR if real usage shows
demand. ADR 0002 Amendment 6 and ADR 0004 Amendment 4 capture the
decision explicitly.

Changes (8 files, +<delta>):

**Code**

1. **lib/providers/base.mjs** — add `CONCURRENCY_LIMIT` to
   `PROVIDER_ERROR_CODES`. JSDoc clarifies the code is synthesised by
   the orchestration layer, not thrown by provider plugins themselves.

2. **lib/providers/index.mjs** — new semaphore primitives:
   - `tryAcquireSpawn(providerName, maxConcurrent)` — atomic
     check-then-increment. Returns `true` on success, `false` if at
     limit. Atomicity rests on the JS single-threaded invariant
     (read + write synchronous, NO `await` between them); module-level
     comment block warns future maintainers against breaking this.
   - `releaseSpawn(providerName)` — decrement; throws on
     under-decrement (defensive bug guard for missing acquire / double
     release). Map.delete at zero for clean memory footprint.
   - `getActiveSpawnCount(providerName)` — returns current count
     (0 for unseen providers). For diagnostics + tests.
   - `DEFAULT_MAX_CONCURRENT_SPAWNS = 4` — defense-in-depth fallback
     matching the v0.1 plugin defaults (anthropic/codex/mistral all
     declare hints.maxConcurrent: 4). Also coerces non-integer / NaN
     / negative inputs to the default.
   - `__resetSpawnCounters()` — internal test seam.

3. **lib/fallback/engine.mjs** — `CONCURRENCY_LIMIT: true` added to
   `HARD_TRIGGER_CODES`. `classifyTrigger` and `evaluateHardTriggers`
   both pick it up via the same lookup. v0.1 live hard-trigger codes
   are now 5 (was 4 post-D34): SPAWN_FAILED, CLI_NOT_FOUND,
   AUTH_MISSING:false, SPAWN_TIMEOUT, CONCURRENCY_LIMIT.

4. **server.mjs** — gate the spawn call in handleChatCompletions at
   BOTH spawn call sites:
   - **Buffered path** (executeHopFn → collectAllChunks): acquire
     before provider.spawn; on failure synthesise
     `ProviderError(CONCURRENCY_LIMIT)` with providerName /
     maxConcurrent / activeSpawns diagnostic fields and throw —
     fallback engine catches and advances. On success, outer try/
     finally wraps the inner D16 truncation-salvage try/catch so
     releaseSpawn fires on EVERY exit path (return, D16 salvage
     return, re-throw).
   - **Streaming path** (single-hop real-SSE branch): acquire BEFORE
     the streaming branch entry. If acquire fails, branch is skipped
     and request falls through to buffered path (whose own gate
     surfaces chain-exhausted for single-hop chains). If acquire
     succeeds, existing streaming try/catch gains
     `finally { releaseSpawn(streamProvider) }` — slot releases on
     stop-chunk completion, generator exhaustion, abort, or any
     exception path. `releaseSpawn` fires at END of stream
     consumption, not when spawn() returns.

**Tests** (test-features.mjs): 431 → 447 (+16):

Suite 18 — D38 — maxConcurrent runtime enforcement:
- 18a: PROVIDER_ERROR_CODES.CONCURRENCY_LIMIT exists
- 18b: evaluateHardTriggers true for CONCURRENCY_LIMIT
- 18c: AUTH_MISSING regression guard (D38 did NOT flip it to hard)
- 18d.1-18d.4: semaphore unit (increment / saturate-no-increment /
  release / map-delete-at-zero)
- 18e: tryAcquireSpawn returns false without side-effect when at limit
- 18f: releaseSpawn throws on under-decrement
- 18g.1-18g.2: DEFAULT_MAX_CONCURRENT_SPAWNS applied for invalid
  inputs (undefined / NaN / negative / non-integer)
- 18h: __resetSpawnCounters clears state
- 18i: HTTP integration — 5 concurrent requests to single-hop
  chain w/ maxConcurrent=2 → peak in-flight exactly 2, 2 succeed,
  3 fail
- 18j: counter releases after buffered request (sequential test)
- 18k: 2-hop chain — saturated primary advances to fallback
- 18l: streaming counter releases at END of stream (not at spawn)

**ADR amendments**

5. **docs/adr/0002-plugin-architecture.md** — Amendment 6 added.
   Removes "Declarative hint only at v0.1" caveat from the
   `maxConcurrent` description in the Provider contract section.
   Adds implementation reference + design-choice rationale (4 points).
   Lists all exported symbols.

6. **docs/adr/0004-fallback-engine.md** — Amendment 4 added.
   CONCURRENCY_LIMIT added to v0.1 hard-trigger taxonomy. Documents
   synthesis-vs-plugin-thrown distinction. Documents first-chunk
   safety (acquire before any res.write). v1.x re-evaluation triggers
   named.

**CHANGELOG**

7. **CHANGELOG.md** — Unreleased sentinel replaced with proper D38
   entry. Per CLAUDE.md release_kit phase_rolling_mode, this lands
   under Unreleased; promotion to ## v0.1.1 happens at the v0.1.1
   release. The D37 phase_rolling_mode gate now correctly fires if
   anyone tags v0.1.x with this content present without promotion —
   intentional.

Pre-commit fold-ins (per evidence-first checkpoint #4):

- **Reviewer Suggestion #1 (test 18c name mismatch)**: 18c is named
  "classifyTrigger returns hard for CONCURRENCY_LIMIT" but body tests
  AUTH_MISSING regression. Renamed header comment to
  "AUTH_MISSING regression guard" and clarified that
  CONCURRENCY_LIMIT classification is covered by 18b.

- **Reviewer Suggestion #3 (activeSpawns diagnostic field)**: server
  .mjs:532 set `concurrencyErr.activeSpawns = maxConcurrent` (the
  limit). Technically correct (since acquire just failed, live
  count == limit) but confuses future readers. Changed to query
  `getActiveSpawnCount(hopProvider)` directly. Added import of the
  new symbol to the lib/providers/index.mjs import block.

- **Reviewer Suggestion #5 (ADR overstatement)**: ADR 0002 Amendment 6
  said getActiveSpawnCount is "exported for /health, diagnostics,
  and tests" but /health integration is not wired at D38. Reworded to
  "exported for diagnostics and tests" + "/health integration
  deferred — when surfaced there will land at providers.status.<name>
  .activeSpawns; not wired at D38." Avoids overstating current state.

Two reviewer suggestions not folded:
- Suggestion #2 (streaming test 18l comment about branch entry
  conditions) — low priority; the test passes and the branch is
  taken (verified by reviewer). Future polish if confusion arises.
- Suggestion #4 (additional test for streaming-saturation → chain-
  exhausted) — code path is straightforward and intentional; 18i
  covers the buffered-path version directly. Defer.

Authority:
- ADR 0002 Amendment 1 (declarative-only caveat) — superseded by
  Amendment 6
- ADR 0002 Amendment 6 (this commit) — runtime enforcement landed
- ADR 0004 Amendment 4 (this commit) — CONCURRENCY_LIMIT added to
  v0.1 hard-trigger taxonomy
- GitHub issue #1 — closed by this commit
- CC 开发铁律 v1.6 § 10.x — independent fresh-context reviewer
- CLAUDE.md release_kit_overlay phase_rolling_mode — no version
  bump; Unreleased entry written

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus,
independent of drafter): APPROVE. Critical depth checks:
- Atomicity in tryAcquireSpawn (lines 285-290 read+set with no
  intervening await) — confirmed; module-level invariant comment
  warns future maintainers
- Release on every exit path: buffered (outer finally wraps inner
  try/catch covering D16 salvage return + normal return + re-throw);
  streaming (try/finally covers stop-chunk return + loop exhaustion +
  catch paths). No double-release path identified.
- Streaming release timing: fires in finally after res.end() at all
  exit paths, never before stream consumption completes
- Counter leak: every code path traced — no orphan acquire identified
- 447/447 tests pass in reviewer's independent npm test run

taodengandClaude Opus 4.7 f784fdb947 fix+docs: D33 — round-5 cleanup batch (F1/F3/F5/F8/F9/F10/F11/F12)
cold-audit catch from 2026-05-24 (round 5)

Round-5 cold-audit cleanup batch. 8 items + 1 release-discipline
reconciliation. Largest batch by line count (582+/39-) but every item
is small-and-focused. 3 P2 items (F1/F3/F5 of which F3 + F1 are real
correctness/observability fixes; F5 backfills /health to spec).

Changes (10 files, +583/-39):

**P2 fixes**

1. **F1 — ALIGNMENT.md mistral authority pin self-contradicted plugin**
   (ALIGNMENT.md): row cited `vibe --prompt --output json` but mistral.mjs
   uses `--output streaming` (the plugin header at lines 360-369 even
   justifies WHY: `--output json` emits single blob, breaks NDJSON
   line-buffered parser). Constitution self-contradicting itself —
   missed across 4 prior rounds. Pin updated to `--output streaming`
   with DOCS-1 reference.

2. **F3 — Deterministic function_call synth ID**
   (lib/ir/openai-to-ir.mjs): deprecated `function_call` translation
   produced `id: \`fc-${Date.now()}\`` → ID flows into normalized
   tool_calls → cache key SHA-256. Two identical requests separated
   by ≥1ms → different cache keys → cache always misses for
   `function_call` request shape. Violates ADR 0005 invariant
   "same inputs → same key, no random, no timestamp."

   Fixed: id is now `fc-<16-hex>` from SHA-256 of `${name}\0${arguments}`.
   NUL separator prevents the (name='ab',args='c') vs (name='a',args='bc')
   collision. 2^64 collision resistance is more than sufficient for
   tool_call ID disambiguation (per-request semantic key, not crypto
   primitive).

**P3 fixes**

3. **F5 — /health invokes per-plugin healthCheck()** (server.mjs +
   docs/openai-spec-pin.md): ADR 0002 says "healthCheck — startup AND
   /health endpoint use this." Pre-D33 /health returned only
   {enabled, available} counts. Now async, iterates loadedProviders,
   awaits each plugin's healthCheck() in try/catch. Returns
   `providers: {enabled, available, status: {<name>: {ok, latencyMs?, error?}}}`.

4. **F8 — X-OLP-Cache reports fallback-hop cache hits** (server.mjs):
   pre-D33 cacheStatus computed from `preCheckHit && fallbackHops === 0`
   — only counted primary-hop cache hits. When fallback fires + the
   fallback hop's getOrCompute returns from cache, header reported
   `miss` despite no spawn happening.

   Fixed: peek BEFORE getOrCompute inside executeHopFn, set
   `lastHopWasCached` closure variable on every hop (last-write-wins
   = serving hop's state). cacheStatus combines
   `lastHopWasCached || (preCheckHit && fallbackHops === 0)`.

   F8 chose option (b) peek-then-getOrCompute over option (a)
   getOrCompute API change because option (a) would break ~15 test
   callsites for marginal benefit. Accepted race window same as
   existing preCheckHit pattern.

5. **F9 — validateProvider hints error message updated** (lib/providers/
   base.mjs): pre-D33 message listed cacheable as missing and
   maxSpawnTimeMs as required. Now: `'hints must be an object with
   { requiresTTY, concurrentSpawnSafe, maxConcurrent } + optional
   { maxSpawnTimeMs, cacheable }'`.

6. **F10 — Dead cache-write branch removed** (server.mjs): the
   `if (hasStopChunk)` check in the streaming stop-less exhaustion
   branch was unreachable (the stop-chunk completion path returns
   earlier inside the for-await loop). Removed the dead code + added
   a comment documenting the invariant.

**Governance/policy**

7. **F11 — Phase rolling mode policy formalized** (CLAUDE.md +
   CHANGELOG.md): 22+ D-day commits accumulated under "Unreleased"
   without per-D version bumps — Iron Rule 5 (release-kit bump-before-
   push) appeared to be silently violated. Reality: per-D bumps would
   produce 30+ noise tags during Phase 1. F11 formalizes the policy:
   intra-Phase D-day commits accumulate under Unreleased; bump+tag
   fires explicitly at Phase close (maintainer-triggered, not
   automated). CLAUDE.md release_kit overlay gains `phase_rolling_mode`
   block documenting the exception with self-pointer ("if Rule 5
   appears silently violated, check this section first"). CHANGELOG
   "Unreleased" gets a notice at top.

   **No version bump, no git tag in D33** — policy formalization only.

8. **F12 — /v1/models created is stable per-model timestamp**
   (models-registry.json + lib/providers/index.mjs + server.mjs +
   docs/openai-spec-pin.md): pre-D33 used Math.floor(Date.now()/1000)
   per request — violates OpenAI spec which treats `created` as
   per-model attribute. Clients caching models by created would see
   spurious updates on every poll.

   Fixed: models-registry.json gains `bootstrapCreated: 1778630400`
   top-level constant + per-model `created` fields where known
   (anthropic claude-{opus,sonnet,haiku} with estimated release dates;
   devstral models from "25-12" suffix; codex models pinned to
   bootstrap pending verified release dates). handleModels uses
   `getModelCreated(modelId)` helper from lib/providers/index.mjs.
   Aliases share canonical's timestamp.

**Tests** (test-features.mjs): 401 → 414 (+13):
- F3 ×3 (same input → same id → same cache key; different name → different)
- F5 ×4 (empty/single/multi/throwing-plugin /health shapes)
- F8 ×1 (2-hop primary-fail + secondary-cache-hit → X-OLP-Cache: hit)
- F12 ×5 (stability/fallback/alias-equals-canonical)

Pre-commit fold-in (per evidence-first checkpoint #4):
- **D33 reviewer flagged F3 empty-args asymmetry** (Concern #1): hash
  input used `?? ''` (empty stays) but emitted IR field used
  `|| '{}'` (empty becomes '{}'). Consequence: `arguments: ''` and
  `arguments: '{}'` emit identical IR but compute different ids →
  different cache keys for semantically-identical requests. The exact
  cache-stability bug F3 was supposed to fix.

  Folded in: canonicalize empty-args to '{}' BEFORE hashing. Hash
  input now matches IR emission exactly. Same line change resolves
  the asymmetry.

Authority:
- ALIGNMENT.md self-amendment (F1 pin correction)
- ADR 0005 invariant "same inputs → same key, no random, no timestamp"
  (F3 restoration)
- ADR 0002 § Provider contract "/health uses healthCheck" (F5)
- ADR 0004 § Observability headers (F8 X-OLP-Cache correctness)
- ADR 0005 § Cache write conditions item 1 (F10 truncation-not-cached
  invariant explicit)
- Iron Rule 5 (F11 release-kit reconciliation)
- OpenAI /v1/models spec — `created` per-model stable (F12)
- CC 开发铁律 v1.6 § 10.x — Round-5 Cold Audit caught all 8

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE_WITH_MINOR. Verified:
- F1 plugin cross-reference (mistral.mjs:360-369) accurately documents
  the rationale
- F3 collision resistance + NUL separator + restored cache invariant
- F5 all 4 cases (empty/single/multi/throwing) work
- F8 closure semantics across multi-hop chains (verified hop-fail +
  fallback-hit case)
- F10 dead code removal preserves the stop-chunk completion path
- F11 phase_rolling_mode policy honest about what happened and what
  the going-forward rule is
- F12 stability across consecutive /v1/models calls; alias-canonical
  parity
- 414/414 tests pass

3 remaining non-blocking suggestions (F3-vs-modern-tool_calls path
canonicalization symmetry; F12 codex models explicit-vs-fallback
writeup mismatch; F8 servingHopWasCached naming) tracked as future
polish; not folded.

taodengandClaude Opus 4.7 c3ba751a8f feat: D27 — round-3 P3 batch (F8 IR validator + F10 ADR amend + F15 /v1/models aliases)
cold-audit catch from 2026-05-24 (round 3)

3 round-3 P3 items batched per IDR. Mixed surfaces but all single-severity
and conceptually independent.

Changes (5 files, +324 / -17):

1. lib/ir/types.mjs — F8 validator extension (+28):
   - `response_format`: must be object with string `.type` (undefined/omitted
     accepted; null, non-object, missing-type all rejected). Forward-compat:
     accepts any string for type so future OpenAI additions (json_schema,
     etc.) flow through without schema bump.
   - `tool_choice`: string form 'auto'/'none'/'required' OR object form
     `{type:'function', function:{name:string}}`. All other shapes rejected.
   Pre-D27 the validator silently accepted any value; the Anthropic plugin's
   `if (irRequest.response_format?.type === 'json_object')` would no-op on
   a malformed string payload.

2. docs/adr/0005-cache-cross-provider.md — F10 Amendment 4 (+8):
   - Documents the IR-vs-body detection ambiguity in § D2: the ADR text
     reads as if detection happens on the IR, but `openai-to-ir.mjs` strips
     `cache_control` from messages per ADR 0003's whitelist policy, so
     IR-side detection is structurally always empty at v1.0
   - Documents the actual v1.0 detection mechanism (server.mjs side-channels
     into the raw body)
   - Documents the cache key `cache_control` slot's always-null status as
     forward-compat (when a future ADR 0003 amendment adds cache_control
     to IR, the slot will start carrying meaningful data without schema bump)
   - Explicit "no code change" — F10 is docs-only

3. lib/providers/index.mjs — F15 alias map export (+11):
   - `getAliasMap()` returns `new Map(_aliasMap)` — defensive copy preventing
     caller mutation of the module-private alias map
   - JSDoc documents use case + defensive-copy intent

4. server.mjs — F15 /v1/models alias surfacing (+25/-7):
   - `handleModels` now emits TWO loops: canonical entries first (preserves
     existing client expectations), then alias entries via `getAliasMap()`
   - Each alias entry has the same 4 OpenAI-spec fields (id/object/created/
     owned_by) — no invented fields per ALIGNMENT Rule 2(b)
   - Disabled-provider alias non-leak: `loadedProviders.has(providerName)`
     gate skips aliases whose target provider is not currently enabled
   - createdTs reused (same per-request timestamp across all entries)
   - JSDoc updated to document new ordering + F15 origin

5. test-features.mjs — +269 / +18 new tests:
   - F8: 13 tests covering response_format (object/string/non-object/missing-
     type) + tool_choice (string variants/object variants/wrong type/no name)
   - F15: 5 tests covering canonical-first ordering, alias presence/count,
     disabled-provider non-leak (with anthropic-only enabled, mistral and
     openai aliases must NOT appear), Rule 2(b) shape conformance

Tests: 358 → 376 (+18). All pass on Node 20.

Reviewer notes (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE. Critical checks verified:
- F8: all 9+ tool_choice rejection axes traced through code (including
  partial-function-object edge cases). The code handles them correctly even
  where tests don't exercise (non-blocking gap).
- F10: amendment substantively correct. One wording-precision note: the
  amendment says "body only" but the actual code is an OR-disjunction
  (hasCacheControl(ir) || extractCacheControlMarkers(body.messages)).
  Functionally identical at v1.0 because IR strips markers, so first
  disjunct is always false. Forward-compat by construction.
- F15: disabled-provider non-leak verified by manual trace with
  anthropic-only enabled — mistral/openai aliases correctly filtered out
  by `loadedProviders.has(providerName)` gate. Test 17e explicitly
  asserts this.
- F15+D17 round-trip: client GET /v1/models → sees alias entry → POSTs
  with alias → getProviderForModel resolves via same _aliasMap → cache
  key uses canonical → response works. Both surfaces read the same Map
  (SPOT).
- F15+D23 cacheable interaction: cacheable opt-out doesn't suppress
  alias surfacing in /v1/models — cacheable is about cache-write behavior
  while discovery should still surface enabled providers. Intentional.

Authority:
- ADR 0003 § Optional fields (response_format + tool_choice IR shape)
- OpenAI Chat Completions API spec (the field semantics)
  https://platform.openai.com/docs/api-reference/chat/create
- ADR 0005 § D2 + Amendment 4 (F10's own amendment landing here)
- ADR 0002 § Loading model + D17 getProviderForModel SPOT (F15's alias
  origin)
- ALIGNMENT.md Rule 2(b) — no invented OpenAI fields
- CC 开发铁律 v1.6 § 10.x — Round-3 Cold Audit caught all 3

Follow-up items (reviewer's non-blocking suggestions, NOT in this PR):
- F8 micro-tests for null/boolean/partial-function inputs (code handles;
  test gap only)
- F10 wording precision on OR-disjunction
- Nested-describe wrapper quirk in test-features.mjs (pre-existing
  structural issue; D26/D27 describes are children of Suite 16 wrapper).
  Cleanup in a future hygiene pass.

taodengandClaude Opus 4.7 cb86807009 refactor(routing): D17 — alias-aware getProviderForModel as routing SPOT (Findings 12 + 13)
cold-audit catch from 2026-05-23

Cold-audit Findings 12 + 13 (both P3, both routing layer). F12: mistral
plugin's models[] included canonical IDs + aliases while anthropic/codex
were canonical-only — inconsistent routing surface (request "sonnet"
returned 503 from anthropic but request "devstral" worked for mistral).
F13: getProviderForModel imported but never called; buildDefaultChain
duplicated the lookup loop — two SPOT-candidate code paths.

Per cold-audit reviewer's option (a): standardize models[] on canonical-
only across all 3 plugins; getProviderForModel becomes alias-aware via
models-registry.json; buildDefaultChain uses getProviderForModel as SPOT.

Changes (4 files, +242 / -50):

1. lib/providers/index.mjs:
   - At module load, builds `_aliasMap: Map<aliasString, {providerName,
     canonicalModel}>` by walking models-registry.json's providers[*].aliases
   - getProviderForModel signature extended: returns `{provider, name,
     canonicalModel}` (was `{provider, name}`). The canonicalModel field is
     the resolved canonical ID for callers that need to use it downstream
     (cache key, observability headers, log events)
   - 3-step resolution order: (1) alias map lookup → if hit AND provider
     loaded → return with canonicalModel; (2) direct canonical scan → return
     with canonicalModel = modelString; (3) null
   - "Alias known but provider not loaded" case correctly falls through
     to step 2 (which will also miss for an alias string) → returns null

2. lib/providers/mistral.mjs:
   - _registryModels stripped to canonical-only: removed the
     `...Object.keys(_registryEntry.aliases ?? {})` spread
   - mistral.models[] now matches anthropic/codex shape (canonical IDs only)
   - Comment block updated to point future readers at getProviderForModel
     as the SPOT

3. lib/fallback/engine.mjs:
   - buildDefaultChain's inline `for ([name, provider] of loadedProviders)`
     scan loop replaced with a single getProviderForModel() call
   - Chain hop's `model` field is now `match.canonicalModel` (was `modelString`)
     — so downstream consumers receive canonical
   - Explicit-chain config path unchanged (kept its pre-existing behavior;
     alias resolution in routing.chains config is a known limitation, tracked
     as a future improvement)

4. test-features.mjs:
   - 17 new tests in `D17 — alias-aware getProviderForModel` describe block:
     anthropic alias coverage (sonnet/opus/haiku/claude), openai aliases
     (codex/codex-spark/gpt5/gpt5-mini), mistral aliases (devstral/
     devstral-2/devstral-small/devstral-small-2), canonical pass-through,
     unknown model → null, alias-to-disabled-provider → null,
     buildDefaultChain integration with alias resolution
   - 3 existing mistral tests rewritten — they were asserting the pre-D17
     inconsistent shape (aliases in mistral.models[]). Now assert the
     post-D17 invariant (aliases NOT in models[]; routing via
     getProviderForModel instead)

Tests: 300 → 317 (+17 new). All pass on Node 20.

Pre-commit fold-in (per evidence-first checkpoint #4 — fold-ins themselves
need second-pass review):

- **D17 reviewer flagged C10**: original engine.mjs comment said
  "downstream (cache key, X-OLP-Model-Used, provider.spawn) receives the
  canonical ID rather than the alias string". The provider.spawn portion
  is incorrect — spawn reads `irRequest.model` (the user's original input),
  which is NEVER rewritten to canonical. Each provider CLI accepts its own
  aliases natively (claude accepts sonnet/opus/haiku; vibe accepts
  devstral/devstral-2; codex accepts its model IDs), so runtime behavior
  is fine, but the comment overstated what D17 actually changes.
  Folded in: corrected comment to honestly describe the canonical flow
  (cache key + X-OLP-Model-Used + logs receive canonical; spawn continues
  to receive irRequest.model). Same class of doc-code drift fix as D11's
  B1 (false maxConcurrent enforcement claim) and D16's "bypasses
  getOrCompute" drift — the discipline is maturing across D-days.

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent

chain[0].model from buildDefaultChain through all downstream consumers
(computeCacheKey, X-OLP-Model-Used, log events) to confirm canonical
flow; then verified provider.spawn paths in anthropic.mjs:231 and
codex.mjs:248 read irRequest.model (user input), confirming the comment
overstatement (now fixed). Verified no alias-canonical collision exists
in current registry (12 aliases vs 10 canonical IDs, zero intersection).
Verified empty-registry edge case + provider-with-model-not-in-registry
edge case.

Follow-up items (reviewer's non-blocking observations, NOT in this PR):
- server.mjs:32 dead import of getProviderForModel — defer to D19 cleanup

taodengandClaude Opus 4.7 (noreply@anthropic.com) 95dc072245 feat(phase-1): land Mistral Vibe provider plugin (D8)
Phase 1 Day 5. Mistral Vibe provider plugin lands as Candidate. STATIC_
REGISTRY now length 3 (anthropic + openai + mistral). vibe CLI not
installed on the orchestrator machine and owner has no Le Chat Pro
subscription, so D8 follows the D6 docs-only authority pattern. D-later
verification (once a tester with a vibe install and subscription is
available) will resolve UNPINNED assumptions A4, A6, A7, A8.

Files:
  NEW:  lib/providers/mistral.mjs (~720 lines) — Mistral Vibe provider.
        Spawns `vibe --prompt PROMPT --output streaming` per docs.
        Reads MISTRAL_API_KEY env var with ~/.vibe/.env fallback.
        Supports VIBE_HOME env override per docs. Mirrors D4/D6 plugin
        structure incl. __setSpawnImpl/__resetSpawnImpl for tests.
  MOD:  lib/providers/index.mjs (+12/-1) — STATIC_REGISTRY now length 3.
        listAllProviderNames returns [anthropic, openai, mistral].
  MOD:  models-registry.json (+26 lines) — providers.mistral with 2
        canonical date-stamped IDs (devstral-2-25-12, devstral-small-2-
        25-12) and 4 short-form aliases for user convenience.
  MOD:  test-features.mjs — Suite 12 with 48 tests covering contract
        conformance, IR translation, mock-spawn behaviour, healthCheck,
        estimateCost, auth-artifact reading.

Authority citations (all WebFetched and verified during reviewer pass):
  DOCS-1: docs.mistral.ai/mistral-vibe/terminal/quickstart — `vibe
    --prompt PROMPT --max-turns 5 --max-price 1.0 --output json` example
    + Output Format Options enumeration: text default, json single blob,
    streaming NDJSON.
  DOCS-2: docs.mistral.ai/mistral-vibe/terminal/configuration — pin
    `~/.vibe/.env`, MISTRAL_API_KEY env var, VIBE_HOME override.
  DOCS-3: docs.mistral.ai/mistral-vibe/introduction/configuration —
    second confirmation of MISTRAL_API_KEY + ~/.vibe/.env (model
    selection via config.toml `/config` slash command, NOT --model
    flag).
  DOCS-4: deepwiki.com/mistralai/mistral-vibe/9.3-cli-commands-reference
    — full flag enumeration confirms no --model flag exists. Programmatic
    mode trigger is --prompt; flags are: --continue, --max-price,
    --max-turns, --output, --prompt, --resume, --setup, --trust,
    --upgrade, --version, --workdir, --no-autofill, --no-header,
    --no-dev, --enabled-tools, --help.
  DOCS-5: mistral.ai/news/devstral-2-vibe-cli — launch announcement,
    names Devstral 2 (123B) and Devstral Small 2 (24B), 256K context,
    pricing $0.40/$2.00 and $0.10/$0.30 per MTok.
  DOCS-6: help.mistral.ai/en/articles/347532 — Vibe included in Le Chat
    Pro.
  DOCS-7: legal.mistral.ai/terms/usage-policy — no anti-third-party
    clauses; ADR 0006 Tier D classification holds.
  DOCS-MAIN: docs.mistral.ai/mistral-vibe/overview — main Vibe overview.
  DOCS-8: docs.mistral.ai/getting-started/models/models_overview —
    canonical Mistral models registry. Pin for date-stamped IDs
    devstral-2-25-12 / devstral-small-2-25-12. Caught by D8 review-2.

Architectural decisions:
  1. `--output streaming` (NOT `json`). Per DOCS-1 verbatim: streaming
     emits NDJSON per message; json emits a single blob at the end.
     Original D8 draft used `json` which is incompatible with the
     plugin's line-buffered stdout parser. Review-2 caught this; fixed
     before commit.
  2. No --model flag. Per DOCS-4 full flag enumeration there is no
     --model flag in programmatic mode. Model selection happens via
     ~/.vibe/config.toml. The IR's `model` field is used by OLP for
     routing only; Vibe uses whatever model is in user-level config.
     Documented in lossy translations + as A5 CONFIRMED-NOT-APPLICABLE.
  3. Canonical IDs primary, short forms as aliases. models-registry.json
     uses devstral-2-25-12 / devstral-small-2-25-12 as primary `id`s
     matching the canonical Mistral models registry; user-facing short
     forms (devstral-2, devstral-small-2, devstral, devstral-small) are
     aliases. Plugin's models[] array includes both canonical IDs AND
     alias keys so getProviderForModel routes either form. Same pattern
     codified for Codex aliases in D6.
  4. Auth precedence: MISTRAL_API_KEY env > ~/.vibe/.env > null.
     Documented in DOCS-2. readAuthArtifact supports
     MISTRAL_VIBE_AUTH_PATH env override for testing.
  5. Mistral stays Candidate. STATIC_REGISTRY.length === 3 but
     loadProviders({}) returns empty Map; only loadProviders({
     enabled: { mistral: true }}) loads it. POST /v1/chat/completions
     devstral-* still returns 503 until config flag is set and E2E
     audit passes.

Reviewer chain (Iron Rule 10):
  Implementer: sonnet (general-purpose).
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict round-1:
    REQUEST_CHANGES (2 blockers caught).
  Reviewer ran npm test (222/222 pass), WebFetched all 8 canonical
    Mistral docs URLs, discovered DOCS-8 (models registry) which
    sonnet missed — exactly the D6 failure pattern, repeated. Reviewer
    independently verified `--output streaming` vs `json` semantics
    against the live docs page text, not paraphrases.

Reviewer blocking findings folded in this commit:
  B-1 (--output json wrong): Plugin now passes `--output streaming` per
    docs verbatim. Test "irToMistral: user message → args with --prompt
    and --output streaming" updated to assert the new arg and reject
    the old one.
  B-2 (canonical models page missed): models-registry.json refactored
    to use date-stamped canonical IDs as primary; short forms as
    aliases. mistral.mjs header adds DOCS-8 as the new canonical
    authority pin for model IDs. Plugin's models[] array merges
    canonical + alias keys so existing routing tests pass with either
    form.
  B-3 (404 claim incorrect): mistral.mjs header DOCS-MAIN updated.
    docs.mistral.ai/mistral-vibe/overview is 200 OK; sonnet's 404
    claim was a path-normalization mismatch.

Reviewer non-blocking suggestions (deferred to D-later / not D8 scope):
  - VIBE_HOME env override has no Suite 12 test (implementation
    present at mistral.mjs:262). Parallel gap to D6 CODEX_HOME.
  - _extractKeyFromDotenv has no direct unit test.
  - config.toml model selection mechanism (Vibe-specific quirk —
    no --model flag means OLP can't pass model per request). A D-later
    ADR note will discuss whether OLP should write a project-local
    ./.vibe/config.toml before spawn or accept the user-level config
    as authoritative.

Test count: 174 (after D6) → 222 (after D8).

Verification:
  node --check on all touched files: clean.
  npm test on Node 25.8.0: 222/222 pass in 210ms.
  STATIC_REGISTRY = [anthropic, openai, mistral] verified.
  hygiene grep: zero personal-name/path/token hits. Fixtures use
    <fake-mistral-api-key> placeholders.

taodengandClaude Opus 4.7 (noreply@anthropic.com) ea9184d2e8 feat(phase-1): land OpenAI Codex provider plugin (D6)
Phase 1 Day 4. OpenAI Codex provider plugin code lands as Candidate.
Anthropic and Codex now both in STATIC_REGISTRY length 2. Codex CLI is
NOT installed on the orchestrator machine, so D6 ships with a docs-only
authority pin; D7 will install the binary, probe real behaviour, and
fix any docs-vs-reality divergences (A3 access-token field, A4 NDJSON
event schema, possibly keyring storage support).

Files:
  NEW:  lib/providers/codex.mjs (586 lines initially, expanded ~10 lines
        via reviewer fold-ins) — Codex provider implementing the v1.0
        contract. spawns `codex exec --json --model <id> [PROMPT|-]` per
        canonical Codex docs.
  MOD:  lib/providers/index.mjs — STATIC_REGISTRY now [anthropic, codex],
        listAllProviderNames() returns 2 entries.
  MOD:  models-registry.json — providers.openai populated with five
        documented model IDs (gpt-5.5, gpt-5.4, gpt-5.4-mini,
        gpt-5.3-codex, gpt-5.3-codex-spark) and four aliases.
  MOD:  test-features.mjs — Suite 11 added with 46 tests covering contract
        conformance, IR translation, mock-spawn behaviour, healthCheck,
        estimateCost, registry length.

Authority citations (all WebFetched and verified during reviewer pass):
  CLI reference: https://developers.openai.com/codex/cli/reference
    Source for `codex exec` subcommand syntax, --json flag, --model -m
    flag, and PROMPT positional including the `-` form for stdin piping.
  Features:      https://developers.openai.com/codex/cli/features
    Reference for the supported-models list.
  Auth:          https://developers.openai.com/codex/auth/
    Canonical pin for `~/.codex/auth.json` plaintext credential file
    and `cli_auth_credentials_store = keyring` OS credential store option.
  Models:        https://developers.openai.com/codex/models
    Canonical pin for the five documented model IDs (each shown as a
    `codex -m <id>` example on the page).
  ChatGPT plan:  https://help.openai.com/en/articles/11369540 — Codex
    runs against ChatGPT subscription budget when OAuth-authenticated;
    OPENAI_API_KEY env path is for `codex login --with-api-key` only,
    not `codex exec` runtime.

Architectural decisions:
  1. Mirror D4 anthropic.mjs structure: file header, lossy translation
     docs, default export = provider object, named exports include
     __setSpawnImpl / __resetSpawnImpl for test injection.
  2. Stdin path uses `args.push('-')` per documented CLI behaviour.
     (Original D6 sonnet draft omitted the positional entirely and wrote
     stdin directly — D6 reviewer pass 2 caught this; corrected before
     commit. D7 E2E confirms.)
  3. Auth artifact path `~/.codex/auth.json` is now documented in the
     header as CONFIRMED per canonical auth doc, not assumed.
  4. Access-token field name remains a defensive 3-name try-order
     (access_token / token / accessToken) because the auth doc does
     not enumerate field names. D7 captures real auth.json post-login.
  5. OPENAI_API_KEY env injection during spawn is intentionally NOT
     done. The auth doc clarifies OPENAI_API_KEY is a login-time input,
     not a runtime override. codex exec reads its own auth artifact.
  6. Codex stays Candidate. loadProviders({}) returns empty Map; only
     loadProviders({ enabled: { openai: true } }) loads it. POST /v1/
     chat/completions gpt-5.5 etc still returns 503 until config flag
     is set + E2E audit passes.

Reviewer chain (Iron Rule 10):
  Implementer: sonnet (general-purpose).
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict
    APPROVE_WITH_MINOR.
  Reviewer ran npm test (174/174 pass with Suite 10 skipped), WebFetched
    all four canonical Codex docs URLs, and discovered two additional
    docs pages (auth + models) that sonnet had missed. Reviewer
    independently verified the documentation citations rather than
    trusting sonnet quotes — Rule 2 (No Invention) is the load-bearing
    check for D6 because no local binary exists to ground-truth the
    plugin.

Reviewer non-blocking findings folded in this commit:
  1. Stdin path corrected: docs explicitly state `Use - to pipe the
     prompt from stdin`. The original draft assumed "no positional →
     stdin"; docs require literal `-`. Fixed in irToCodex; test
     "irToCodex: multiline prompt uses stdin path (useStdin=true) with
     - positional" updated to assert args.includes('-').
  2. Model registry expanded from 3 to 5 entries per canonical models
     doc. Added gpt-5.4-mini and gpt-5.3-codex-spark. Removed the
     misread Rule 2 comment that justified omitting -spark suffix —
     the docs literally show `codex -m gpt-5.3-codex-spark`, so the
     -spark variant is a separate model not a -codex normalization.
     New aliases: codex-spark, gpt5-mini.
  3. File header A2 upgraded from "assumed" to "CONFIRMED" with the
     canonical auth doc URL cited.
  4. File header now cites both auth and models canonical URLs at the
     top, alongside reference and features.

Reviewer findings deferred to D7:
  - OS credential store / keyring support. Codex docs mention
    cli_auth_credentials_store = keyring as an alternative to file
    storage. The Anthropic plugin supports macOS keychain via security
    find-generic-password; Codex equivalent unknown without inspecting
    a real install. D7 will install codex, run codex login, see what
    keyring entry codex creates (if any), and mirror the Anthropic
    keychain support pattern.
  - Real NDJSON event schema (field names). Defensive 4-shape parser
    handles the most common conventions; D7 captures real stdout and
    pins the schema.
  - access_token field name in auth.json. D7 captures the real auth
    artifact and removes unused fallback names.

Test count: 128 (after D5) → 174 (after D6).

Verification:
  node --check on all touched files: clean.
  npm test on Node 25.8.0: 174/174 pass in 210ms with Suite 10 skipped.
  Test "codex.models contains all 5 docs-listed model IDs" passes.
  Test "irToCodex: multiline prompt uses stdin path with - positional"
    passes (asserts args.includes('-')).
  Hygiene grep: zero personal-name/path/token hits.

taodengandClaude Opus 4.7 (noreply@anthropic.com) c175e8994c feat(phase-1): land Anthropic provider plugin (D4)
Phase 1 Day 2. Anthropic provider plugin code lands, plus contractVersion
field added across base.mjs and validated strictly. Anthropic stays
CANDIDATE per ALIGNMENT.md Provider Inventory — D5 flips to Enabled after
the real spawn E2E audit passes. POST /v1/chat/completions claude-* still
returns 503 until then.

Files:
  NEW:  lib/providers/anthropic.mjs (445 lines)
  MOD:  lib/providers/base.mjs (+8 lines — contractVersion enforcement)
  MOD:  lib/providers/index.mjs (+37 lines — STATIC_REGISTRY adds anthropic
        + getProviderByName helper)
  MOD:  models-registry.json — populates providers.anthropic with 3 models
        opus-4-7 / sonnet-4-6 / haiku-4-5, alias map, candidate marker
  MOD:  test-features.mjs (+481 lines — Suite 6: 37 new tests covering
        contract conformance, contractVersion enforcement, IR translation,
        mock-spawn behaviour, healthCheck, estimateCost)

Authority citations (all verified by independent reviewer against actual
OCP byte offsets):
  Spawn pattern: OCP server.mjs:542 stdio shape, port verbatim.
  CLI args: OCP server.mjs:384-414 buildCliArgs pattern — -p, --model X,
    --output-format text, --no-session-persistence (session-resume and
    permissions branches stripped per OLP no-state architecture).
  stdin write: OCP server.mjs:586-587 verbatim.
  Stdout text handling: OCP server.mjs:735-748 raw d.toString per chunk
    no JSON envelope, matches --output-format text.
  Auth chain: OCP server.mjs:864-888 (env CLAUDE_CODE_OAUTH_TOKEN ->
    ~/.claude/.credentials.json -> macOS keychain with both label formats
    "claude-code-credentials" and "Claude Code-credentials") ported in
    same priority order. One delta vs OCP: OLP guards keychain branch on
    process.platform === darwin, OCP relies on try/catch on Linux. Both
    behave identically; OLP avoids an unnecessary shell-out.
  Env cleanup: OCP server.mjs:530-534 — delete CLAUDECODE, ANTHROPIC_
    API_KEY, ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN. CLAUDECODE
    clobbering pitfall inherited per memory.

Architectural decisions:
  1. Anthropic stays Candidate at D4. STATIC_REGISTRY.length === 1 but
     loadProviders({}) returns empty Map. Suite 7 HTTP integration tests
     continue to verify 503 with no_enabled_provider for any claude-*
     model. D5 changes the config default to enable: { anthropic: true }
     and adds the real E2E spawn test.
  2. contractVersion === 1.0 strictly enforced (F3 fold-in from D3
     review). validateProvider in base.mjs rejects providers missing or
     having any other version string. Suite 6 includes 4 tests covering
     missing / 0.9 / 1.0 / undefined cases.
  3. quotaStatus returns null at D4 with a TODO comment pointing at the
     ALIGNMENT.md 2026-06-16 one-shot audit. Anthropic Agent SDK Credit
     pool balance API has not been pinned; verification scheduled for
     2026-06-16 per OLP one-shot audits.
  4. estimateCost returns shape but usd: null. Per-million-token rates
     not pinned at D4. Lands when models-registry.json gains a pricing
     field in a later phase.
  5. Lossy translations explicitly documented in anthropic.mjs file
     header per ADR 0003 § Lossy-translation documentation requirement.
     Includes response_format json_object (system-prompt augmented),
     top_p (no --top-p flag), tool_choice required (no flag), and
     request-level tools[] + assistant tool_calls + tool_call_id
     (text-in/text-out CLI cannot consume structured tool wire format).
     The tools[] documentation gap was a reviewer non-blocking finding;
     folded in this commit.

Mocking discipline: no real claude -p spawn in any D4 test. spawn-path
coverage uses __setSpawnImpl injection of fake child_process. No real
OAuth tokens or API keys in fixtures — all use placeholder strings
fake-oauth-token / fake-token. Auth path computed via
path.join(homedir(), .claude, .credentials.json), no hardcoded
/Users/<name> literal.

Reviewer chain (Iron Rule 10):
  Implementer: sonnet (general-purpose).
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict
    APPROVE_WITH_MINOR.
  Reviewer ran npm test (98/98 pass) and verified all five OCP citations
    at the actual byte offsets in /Users/taodeng/ocp/server.mjs. All
    citations confirmed accurate.

Reviewer non-blocking findings:
  1. tools[] and tool_calls lossy-translation undocumented — FOLDED IN
     this commit (anthropic.mjs header rewritten with full lossy list).
  2. with type json import attribute Node 20 compat — DEFERRED to CI
     verification. The syntax is stable on Node 20.10+ and the CI
     setup-node@v4 with node-version 20 resolves to latest 20.x. If
     CI Node 20 leg fails, mitigation is bump engines.node to >=20.10
     or swap both import-attribute lines for readFileSync + JSON.parse.
  3. CLI_NOT_FOUND error code declared but never thrown — DEFERRED to
     a future commit. Pure cosmetic; could distinguish ENOENT from
     generic spawn errors but no functional impact.

Test count: 61 -> 98 (+37 D4 tests).

Verification:
  node --check on all touched files: clean.
  npm test on Node 25.8.0: 98/98 pass in 209ms.
  Reviewer-run npm test independently: 98/98 pass.
  loadProviders({}) returns empty Map (verified by orchestrator and
    reviewer): Anthropic Candidate gate holds.
  hygiene grep: no personal names, no /Users/<name>/ literals, no real
    OAuth tokens or API keys.

taodengandClaude Opus 4.7 (noreply@anthropic.com) e2e67de23a feat(phase-1): land IR + plugin loader + server skeleton (D3)
Phase 1 Day 1. First executable code lands. Zero providers wired yet
(per ALIGNMENT.md "v0.1 ships 0 Enabled Providers"); the server starts
clean and POST /v1/chat/completions returns 503 with no_enabled_provider.

Files added:
  lib/ir/types.mjs            - IR v1.0 schema + validators (ADR 0003)
  lib/ir/openai-to-ir.mjs     - OpenAI Chat Completions to IR
  lib/ir/ir-to-openai.mjs     - IR chunks to OpenAI SSE / non-stream
  lib/providers/base.mjs      - Provider contract + validateProvider + ProviderError
  lib/providers/index.mjs     - Static empty registry stub (ADR 0002)
  server.mjs                  - HTTP listener with createOlpServer factory + main guard
  test-features.mjs           - 61 tests across 7 suites (IR / provider / HTTP)

Files modified:
  package.json - main and scripts.start/test added back; targets now exist.

Authority citations:
  IR fields and translation direction: ADR 0003 sections Decision and
    Translation direction model.
  Provider contract (9 fields): ADR 0002 section Provider contract v1.0
    interface.
  Entry surface routes (health, v1/models, v1/chat/completions): OLP v0.1
    spec section 4.1 single-protocol entry; ALIGNMENT.md Authority 2.
  Zero-Enabled-Providers behaviour: ALIGNMENT.md Provider Inventory.

Architectural decisions worth recording:
  1. server.mjs uses a createOlpServer factory plus an import.meta.url
     main guard. The factory returns an unbound http.Server; only the
     main-script invocation calls .listen(). Tests import the real
     server.mjs and exercise the real router. No parallel implementation
     in the test file.

     This pattern was a fold-in from the orchestration step. The initial
     sonnet draft put a top-level server.listen call in server.mjs, which
     forced test-features.mjs to reimplement the router inline (a false-
     confidence trap because the real server logic would never be tested).
     Refactored before reviewer dispatch.

  2. lib/providers/index.mjs ships an empty STATIC_REGISTRY array, not a
     placeholder with dummy entries. ALIGNMENT.md Provider Inventory says
     v0.1 ships zero Enabled Providers; the registry honors that exactly.
     Phase 1 Day 2 adds the first import (Anthropic) when its plugin lands.

  3. BadRequestError lives in openai-to-ir.mjs and ProviderError in
     base.mjs. Reviewer suggested relocating to a shared lib/errors.mjs
     once the count exceeds two; deferred to Phase 1 Day 2 to ship with
     the third typed error class.

  4. contractVersion: '1.0' on each provider plugin: not enforced at D3
     because no providers exist yet. Reviewer flagged for Phase 1 Day 2
     tightening when the first provider lands.

Reviewer chain (Iron Rule 10):
  Initial implementer: sonnet (general-purpose).
  Refactor (createOlpServer + main guard) by the orchestrator after
    catching the inline-router parallel-implementation issue.
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict
    APPROVE_WITH_MINOR.

Reviewer's two non-blocking findings folded in:
  F1: removed unused createServer import from test-features.mjs line 12,
      left over from the refactor.
  F2: replaced finish_reason value 'error' with 'stop' in both the
      streaming error chunk path (lib/ir/ir-to-openai.mjs line 72) and
      the non-streaming error aggregation path (lib/ir/ir-to-openai.mjs
      line 153). The 'error' value is not in OpenAI's documented
      finish_reason enum (stop / length / tool_calls / content_filter /
      function_call / null), so emitting it would violate ALIGNMENT.md
      Rule 2 (b). Provider errors are now surfaced via a top-level
      response.error object plus an inline content marker. The matching
      test assertion at test-features.mjs line 325 was updated to verify
      finish_reason stays within the OpenAI enum.

Note on the F2 fold-in:
  Reviewer pointed only at the streaming path (line 72). After applying
  that fix I ran grep across lib/ and test-features.mjs for the same
  invention pattern and caught a second hit at line 153 (non-streaming
  aggregation). This is the "fold-in must grep the full repo, not only
  the file the reviewer named" discipline from
  ~/.cc-rules/memory/feedback/evidence_first_under_speed_pressure.md.
  Both hits are fixed in this commit.

Verification:
  node --check on all 7 new files plus modified package.json plus
    server.mjs plus lib/ir/ir-to-openai.mjs - all clean.
  npm test - 61/61 pass in 209ms, no flakes, no skipped.
  OLP_PORT=14001 node server.mjs followed by curl /health returns
    proper JSON; curl /v1/models returns 200 empty list; server shuts
    down cleanly on signal.
  grep "finish_reason.*error" returns zero hits across lib/ and tests.
