Unreleased

D48 — ADR 0008 Phase 3 design draft (Dashboard + audit query layer)

First Phase 3 D-day. Design-only. Ratifies the storage / query model / rotation / dashboard / refresh / scope decisions ahead of D49+ implementation D-days. Opens ADR 0007 § 12 deferral for Dashboard + audit query layer + rotation.

• New file docs/adr/0008-dashboard-and-audit-query.md (~390 lines): 13 sections + Consequences + Authority citations. Decisions per maintainer-pinned lanes:
  • Lane 1 (tech stack): static HTML + vanilla JS + fetch (no build step; matches OLP "no bundler" ethos)
  • Lane 2 (query model): in-memory scan of audit ndjson per request (defers SQLite hybrid per ADR 0007 § 13)
  • Lane 3 (rotation): daily rotation, audit-YYYY-MM-DD.ndjson on first append after UTC midnight + optional bin/olp-audit-rotate.mjs external cron
  • Lane 4 (refresh): 30s page poll (no SSE infra at v0.3.0)
  • Lane 5 (dashboard scope): full per spec § 4.6 — 4 panels (quota / per-provider 24h counts / 30d spend trend / top fallback chains)
• docs/adr/README.md index: added ADR 0008 row with one-paragraph summary.
• CHANGELOG.md Unreleased: this entry.
• Phase 3 sprint shape: D49 lib/audit-query.mjs + Suite 23 → D50 /v0/management/* endpoints + Suite 24 → D51 dashboard.html → D52 daily audit rotation + Suite 25 → D53 tried_providers schema fix (D45 P2 deferral) → D54 E2E + docs → D55 Phase 3 close → v0.3.0 (maintainer-triggered).
• Fold-in (fresh-context opus reviewer findings — 1 P2 + 2 P3, all ADR-text polish):
  • P2 § 8 + § 10 #9 gating-mode wording — original § 8 implied a new "block non-owner identities" behaviour without naming it; § 10 #9 tested only the universal allow_anonymous: false 401 case. Fix: § 8 now formalizes two gating modes — owner_only_trim (Phase 2 /health pattern) vs owner_only_block (new Phase 3 management-endpoints pattern) — and explains the management endpoints are owner_only_block because the entire payload is sensitive. § 10 #9 now covers both 401 paths (with allow_anonymous: true + no header → anonymous identity → still 401 because management endpoints are owner_only_block; AND with allow_anonymous: false + no header → 401 at the authenticate middleware itself).
  • P3 /cache/stats citation accuracy — original § 7.4 + Authority block cited "ADR 0005 § Cache stats" which is not a real section. Corrected: planning authority is OLP v0.1 spec § 4.6; ADR 0005 references the endpoint in Consequences/Mitigations (~line 279) for the per-(provider, model) cache-hit-rate breakdown surface.
  • P3 cacheStore.stats() shape gap — § 7.4 now explicitly acknowledges the current shape ({ hits, misses, size, inflightCount } global aggregate) lacks the per-(provider, model) breakdown spec § 4.6 implies; Phase 3 Panel 2 sources per-provider counts from aggregateRequests (audit-side) instead. If a future panel needs the breakdown, D50 amends the store shape + an ADR 0005 amendment fires at that time. Phase 3 acceptance criteria do not require the breakdown.
• Test count: 544 → 544 (design-only, no test change).
• Authority: ADR 0007 § 12 (opens deferral) + § 13 (rejects SQLite at Phase 3 per Node baseline); v0.1 spec § 4.6 / § 4.7 (Dashboard + observability endpoints planning authority); OCP dashboard.html (prior art); CC 开发铁律 v1.6 § 10 — fresh-context opus reviewer required for design ADR; Phase 3 kickoff via maintainer "go" 2026-05-25 + standing-autopilot grant; PR #25 fresh-context opus reviewer findings (3 polish items).

v0.2.0 — 2026-05-25

Phase 2 — Multi-key auth + audit + owner gating + keygen CLI (D43-A → D47)

Overview. v0.2.0 closes Phase 2 — the multi-key authentication track that grew OLP from single-tenant anonymous-only proxy (v0.1.1) to a multi-identity deployment with per-key cache isolation, audit attribution, owner-vs-guest header gating, and a reproducible bootstrap CLI. 6 D-day commits (D43-A through D47) shipped between 2026-05-25 (single intensive session under the standing-autopilot grant). All 11 ADR 0007 § 10 acceptance criteria are implemented + tested.

Test count: 468 (v0.1.1) → 544 (v0.2.0). +76 tests across the Phase 2 arc.

ADR 0007 § 10 acceptance criteria — final ship status

#	Criterion	Covering tests
1	Per-key cache namespace isolation	Suite 20i
2	Anonymous prod-default off → 401	Suite 20a
3	Anonymous dev-mode on → 200	Suite 20g
4	Owner-vs-guest /health gating	Suite 21a-d
5	Owner-vs-guest X-OLP-Fallback-Detail gating	Suite 21e-h
6	Post-revoke 401 within next request	Suite 19o + Suite 20e
7	Manifest atomicity + revoke-dominates-touch	Suite 19y-1..4
8	Audit ndjson round-trip + PII guard	Suite 20j + 20j-stream + 20j-401
9	Bootstrap keygen surface reproducible	Suite 22
10	OLP_OWNER_TOKEN env override	Suite 19p + Suite 20f
11	providers_enabled 403 scope enforcement	Suite 20h

Known limitations carried beyond v0.2.0

Phase 2 functional scope is complete. The following remain as Phase 3+ deferrals (tracked in docs/v1x-roadmap.md + new entries below):

• Dashboard (dashboard.html) — owner-only multi-provider quota / fallback / cache-hit-rate panels. Per ADR 0007 § 12 + v0.1 spec § 4.6. Phase 3 mainline.
• Audit query layer + rotation — audit.ndjson is append-only at v0.2.0; aggregate queries + log rotation deferred to Phase 3 alongside Dashboard.
• tried_providers semantics on key_no_provider_access 403 — schema currently reports filter-rejected hops as "tried"; either ADR § 8 amendment (rename / add field) or D46+ semantic fix. Noted by D45 opus reviewer.
• Per-provider per-key auth artifact mapping — ADR § 12 explicit out-of-scope. Per-key cache + audit isolation works; per-key per-provider OAuth tokens (e.g., two OLP keys each authenticated to different OpenAI Codex accounts) is Phase 3+ work.
• SQLite migration (Option 3 hybrid) — ADR § 13 documents the forward path; trigger is Dashboard / SQL-aggregate-quota / multi-second audit-query workload. Requires engines bump (>=22.13.0 or >=23.4.0) per ADR § 11 as a separate prior PR.

D47 — bin/olp-keys.mjs keygen CLI (Phase 2 functional scope closes)

Fourth Phase 2 implementation D-day. Closes ADR 0007 § 10 acceptance criterion #9 (bootstrap workflow must be reproducible without manual file editing) by shipping a minimal keygen CLI per § 9.1. Phase 2 functional scope is complete with this D-day — remaining work is Phase 2 close → v0.2.0 (maintainer-triggered, explicit per CLAUDE.md release_kit.phase_close_trigger).

• New file bin/olp-keys.mjs (~250 lines): subcommand CLI with three subcommands:
  • keygen [--owner] [--name=<label>] [--tier=guest|owner] [--providers=<csv>] [--force] — creates a key + prints plaintext token to stdout ONCE; manifest stores only SHA-256 hash. --force revokes existing owner keys before creating the new owner (recovery flow per ADR § 9.3). --providers=* (default) or comma-separated allowlist.
  • list [--owner-only] [--include-revoked] — lists keys with token_hash redacted (lib/keys.mjs listKeys already redacts).
  • revoke --id=<key-id> — marks the key's revoked_at; idempotent (already-revoked → no-op + status message); missing id → exit 2.
  • Common flag --olp-home=<path> overrides ~/.olp/; defaults to OLP_HOME env or ~/.olp/.
• package.json bin field: olp-keys → ./bin/olp-keys.mjs so npx olp-keys ... resolves; also npm run olp-keys ... via scripts.
• Module shape: CLI exposes runCli(argv, { out, err }) so tests can invoke it with synthetic argv + IO writers (no process spawn). Main guard auto-runs when invoked as entrypoint.
• Plaintext token discipline: per ADR § 5 + § 9.1, plaintext is printed exactly once on stdout. Never logged, never written to manifest, never written to audit. Operators must capture immediately; lost → --force revoke + regenerate.
• --force async correctness: cmdKeygen is async and awaits each revokeKey (which is async — acquires per-key write lock per § 6.4). Sequence: revoke each existing owner manifest atomically → then createKey for new owner. Avoids the race where create-new runs before revoke-old completes.
• Test surface (Suite 22, +20 tests — 524 → 544):
  • 22a-1..5: parseArgv unit tests (--flag=value, --flag value, boolean, mixed positional)
  • 22b-1..5: keygen subcommand (owner default, name+providers, missing-name error, invalid-tier error, --force revoke-then-create flow with isolation tmpdir)
  • 22c-1..3: list subcommand (empty, populated with token_hash-redaction check, --owner-only filter)
  • 22d-1..4: revoke subcommand (valid id, idempotent re-revoke, missing-id error, nonexistent-id error)
  • 22e-1..3: top-level CLI behaviour (--help / no args / unknown subcommand exit codes)
• Documentation: AGENTS.md lib/keys.mjs marker promoted to ✅; new bin/olp-keys.mjs entry. Implementation-status-note + shipped-set updated. README.md Implementation Status table gains bin/olp-keys.mjs row; Known limitations note updated to "Phase 2 functional scope complete; close pending"; new "Bootstrap workflow" section with copy-pasteable npx commands + recovery flow.
• Test count: 524 → 544 (+20 D47 tests in Suite 22).
• Authority: ADR 0007 (multi-key auth — § 5 token format, § 9.1 minimal keygen command surface, § 9.3 recovery, § 10 acceptance criterion #9 covered); CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased; standing autopilot grant.

D46 — owner-vs-guest gating for /health + X-OLP-Fallback-Detail (Phase 2 closes header observability gap)

Third Phase 2 implementation D-day. Closes ADR 0007 § 10 acceptance criteria #4 (/health payload trimming for non-owner) + #5 (X-OLP-Fallback-Detail emission gating per fallback_detail_header_policy). Phase 2 server surface is now fully gated end-to-end; remaining D-days are keygen CLI surface (D47+) and Phase 2 close (v0.2.0, maintainer-triggered).

• server.mjs handleHealth identity-aware payload per ADR § 7.1:
  • Auth gate at top — authenticate(req) returns 401 for unauth + allow_anonymous: false (consistent with /v1/* routes); 200 with trimmed payload for anonymous / guest; 200 with full payload for owner.
  • Trim controlled by _authConfig.owner_only_endpoints — if /health is in the list, non-owner gets { ok: true, version }; else (operator removes it) full payload to everyone (v0.1.1 opt-out knob).
  • touchLastUsed fired on res.on('finish') for filesystem identities (matches /v1/* pattern). No audit row on /health — high-volume monitoring endpoint, audit volume noise not justified at Phase 2 (would land with Phase 3 Dashboard if aggregate /health stats become needed).
• server.mjs withFallbackDetailHeader identity-aware emission per ADR § 7.2:
  • New helper shouldEmitFallbackDetailHeader(olpIdentity) reads _authConfig.fallback_detail_header_policy:
    • 'owner_only' (default) → emit only when olpIdentity.owner_tier === 'owner'
    • 'all' → emit unconditionally (v0.1.1 opt-back-in for operators who want the diagnostic header for all identities)
    • 'none' → suppress unconditionally
  • When olpIdentity is null (pre-auth error paths), defaults to emit — preserves the v0.1.1 ungated behaviour for pre-auth errors where identity is unknown.
  • withFallbackDetailHeader signature gains a third olpIdentity argument; both call sites in handleChatCompletions updated to pass olpIdentity.
• Test surface (Suite 21, +9 tests + 1 added in Suite 20 — 515 → 524):
  • 20m /health with no auth + allow_anonymous=false → 401 (consistency with /v1/* routes)
  • 21a-d /health payload trimming (criterion #4): anonymous trimmed; guest trimmed; owner full; owner_only_endpoints: [] opts out (guest gets full)
  • 21e-h X-OLP-Fallback-Detail emission gating (criterion #5): owner_only + guest → header absent; owner_only + owner → header present + valid JSON; 'all' + guest → header present (v0.1.1 opt-back); 'none' + owner → header absent (full suppression). Tests use a 2-hop chain (anthropic primary fail + openai secondary) to produce non-empty fallbackDetail for the header content.
• Test-mode setup updated: the global __setAuthConfig({ allow_anonymous: true }) was extended to also pass owner_only_endpoints: [] + fallback_detail_header_policy: 'all' so pre-D46 tests (Suite 18, F5 /health tests, D40 fallback-detail tests, etc.) continue to pass without modification — Suite 21 explicitly overrides per-case to exercise the production-default-gated paths.
• Documentation: AGENTS.md lib/keys.mjs marker updated to reflect D46 ship; Implementation-status-note updated. README.md Implementation Status row + Known limitations "Multi-key auth" note rewritten to reflect D46 ship + remaining keygen CLI.
• Test count: 515 → 524 (+9 D46 tests).
• Authority: ADR 0007 (multi-key auth — §§ 7.1 + 7.2 implementation contracts + § 10 acceptance criteria #4 + #5 covered); ADR 0004 Amendment 5 (D40 ratification of "Phase 2 will re-introduce owner-vs-non-owner gating when lib/keys.mjs lands" — this D-day fulfils the deferral); CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased; standing autopilot grant (~/.cc-rules/memory/auto/standing_autopilot_phase_2.md in cc-rules bf0ed9a).

D45 — server.mjs auth integration + lib/audit.mjs (Phase 2 wire-up)

Second Phase 2 implementation D-day. Wires the D44 lib/keys.mjs identity layer into the request flow + lands lib/audit.mjs per ADR 0007 § 6.2 + § 8. Closes acceptance criteria #1 (per-key cache isolation, validation-side end-to-end), #2 (anonymous prod-default off), #3 (anonymous dev-mode on), #6 (post-revoke 401 within next request — full), #8 (audit ndjson round-trip), #10 (OLP_OWNER_TOKEN env override — full server-side), #11 (providers_enabled 403 scope). Owner-vs-guest gating for /health + X-OLP-Fallback-Detail (criteria #4, #5) remains in D46 scope.

• New file lib/audit.mjs (~75 lines): appendAuditEvent(event, opts) writes one JSON event per line to ~/.olp/logs/audit.ndjson (file 0600, dir 0700). § 6.2 retry semantics: warn + 1 retry on first failure; per-process drop counter + warn on second failure; NEVER throws. Per-call OLP_HOME env resolution (matches lib/keys.mjs). Exports getAuditDropCount for future /health surface.
• lib/keys.mjs extended with loadAuthConfigSync({ olpHome }) reading the auth block from ~/.olp/config.json with defaults per ADR § 7.2 (allow_anonymous: false, owner_only_endpoints: ['/health'], fallback_detail_header_policy: 'owner_only'). Both lib/keys.mjs + lib/audit.mjs now resolve OLP_HOME env per call (precedence: opts.olpHome → process.env.OLP_HOME → ~/.olp) so tests and operator deployments can redirect without code edits.
• server.mjs auth middleware integration:
  • extractToken(req) parses Authorization: Bearer <token> first, then x-api-key: <token>.
  • authenticate(req) calls validateKey(token, { allowAnonymous: _authConfig.allow_anonymous }); returns identity on success, 401 { auth_required | invalid_or_revoked_key } on failure.
  • isProviderEnabled(olpIdentity, providerKey) enforces providers_enabled allowlist ('*' = all).
  • _authConfig loaded at startup; warn auth_allow_anonymous_enabled fires if allow_anonymous: true so the relaxed posture is visible. Test seams __setAuthConfig / __resetAuthConfig.
  • handleChatCompletions and handleModels both gated by authenticate(req) at top. Audit ctx object built throughout the handler lifecycle; res.on('finish') appends the row + fires touchLastUsed async (best-effort).
  • Identity-vs-credentials separation: olpIdentity (the new validated identity) is consumed for cache namespacing + providers_enabled + audit; authContext passed to provider.spawn() REMAINS null so providers continue their own credential discovery (env / keychain / file). Per-provider per-key credential mapping is Phase 3+ scope per ADR § 12.
  • handleChatCompletions chain filtered by chain.filter(hop => isProviderEnabled(olpIdentity, hop.provider)); empty result returns 403 key_no_provider_access with helpful diagnostic message.
  • keyId = olpIdentity.keyId (replacing hardcoded '__anonymous__' at the cache call sites).
  • Audit captures fields throughout: post-auth (key_id, owner_tier); post-IR (model); post-chain-success (provider, fallback_hops, tried_providers, cache_status); post-chain-exhausted (error_code, providerUsed=chain[0], cache_status='miss'). Status code + latency populated on res.on('finish').
• Test surface (Suite 20, +15 tests, 499 → 514):
  • 20a-d: header parsing + valid key happy paths (Bearer / x-api-key / invalid → 401)
  • 20e: revoked key 401 (closes criterion #6 end-to-end)
  • 20f: OLP_OWNER_TOKEN env override returns 200 (criterion #10 full coverage)
  • 20g: allow_anonymous: true + no header returns 200 (criterion #3)
  • 20h + 20h-extra: providers_enabled: ['mistral'] for anthropic model → 403; '*' baseline returns 200 (criterion #11)
  • 20i: per-key cache namespace isolation — keys A/B with identical payload do not share cache (criterion #1 end-to-end)
  • 20j + 20j-401: audit.ndjson written with § 8 schema fields including PII guard; 401 path also appends (criterion #8)
  • 20k: filesystem key last_used_at populated after first successful request (D45 touchLastUsed wire)
  • 20l + 20l-200: /v1/models also enforces auth (consistent gating across /v1/*)
• Test-mode setup: test-features.mjs sets process.env.OLP_HOME to a tmpdir at module load so audit + key writes don't pollute ~/.olp/. After the server.mjs import resolves, calls __setAuthConfig({ allow_anonymous: true }) so pre-D45 HTTP integration tests (Suite 18 etc.) that don't pass an Authorization header continue to pass as anonymous; Suite 20 explicitly overrides per-case for production-default-off coverage.
• Documentation: AGENTS.md lib/keys.mjs 🟡 marker updated + new lib/audit.mjs entry; AGENTS.md Implementation-status-note + shipped-set updated. README.md Implementation Status table gains lib/audit.mjs row + lib/keys.mjs row updated; Known limitations "Multi-key auth" note rewritten to reflect D45 ship + D46 follow-up; new env-vars and config block surfaced for users.
• Test count: 499 → 515 (+15 initial Suite 20 tests + 1 fold-in regression test 20j-stream covering opus-P1 streaming audit-fidelity).
• Fold-in (CI-fail recovery + fresh-context opus reviewer findings, 1 CI + 1 P1 + 2 P2 + 1 P3):
  • CI Node 24 failure — Suite 20 setup did not stub CLAUDE_CODE_OAUTH_TOKEN before the mock spawn ran; lib/providers/anthropic.mjs _spawnAndStream checks for an OAuth token BEFORE invoking the (mock) spawn, so the AUTH_MISSING pre-check fired and every Suite 20 200-expecting test 502'd on CI Node 24 (local Node 22 had the env from the maintainer's claude install). Fixed by ensureSuite20FakeOAuth / restoreSuite20OAuth helpers in makeSuite20Server / teardownSuite20; matches the existing pattern used at Suite 9 line ~2154 (test-fake-oauth-token-for-cache-tests).
  • P1 real-streaming audit fidelity — single-hop streaming success path (server.mjs ~L1050+ if (ir.stream && chain.length === 1 && !bypassCacheForFirstHop ...)) did not populate auditCtx.provider / tried_providers / cache_status, so audit rows for the most common deployed shape carried provider: null. Fixed by stamping these fields at the top of the streaming branch (between the streamPlugin null-check and the streamHeaders build) and amending error_code on the two streaming failure exit paths (streaming_error_after_first_chunk + streaming_error_before_first_chunk). New regression test 20j-stream makes a streaming request and asserts the audit row's provider, cache_status, and tried_providers fields are populated.
  • P2 global test tmpdir cleanup — process.env.OLP_HOME = mkdtempSync(...) at module load left a /var/folders/.../olp-test-home-* directory leak per npm test run. Fixed by process.on('exit', () => rmSync(...)) registered immediately after the mkdtempSync. Best-effort; never throws at exit.
  • P3 handleModels 401 lacks OLP diagnostic headers — handleChatCompletions 401 path passes olpErrorHeaders({ startMs }) but handleModels did not. Aligned by adding the same headers to the handleModels authResult.ok=false return.
  • Deferred (acknowledged by reviewer as non-blocking): P2 tried_providers semantics on key_no_provider_access 403 — schema currently reports filter-rejected hops as "tried" which a downstream Dashboard would misread; either ADR § 8 amendment (rename / add field) or D46+ semantic fix.
• Authority: ADR 0007 (multi-key auth — §§ 5/6.2/7/9.4 implementation contracts + § 10 acceptance criteria #1/#2/#3/#6/#8/#10/#11); CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased; Phase 2 kickoff handoff (~/.cc-rules/memory/handoffs/2026-05-25-phase-2-kickoff.md in cc-rules d9da966); standing autopilot grant (~/.cc-rules/memory/auto/standing_autopilot_phase_2.md in cc-rules bf0ed9a).

D44 — lib/keys.mjs core landed (multi-key auth, no server wire-up yet)

First Phase 2 implementation D-day. Lands the lib/keys.mjs module per ADR 0007 §§ 5/6.1/6.3/6.3.5/6.4/9.4. Identity / lifecycle layer for OLP API keys is now in-tree; server.mjs integration scheduled D45 (until then, requests still use the hardcoded '__anonymous__' cache namespace — no behavioural change at v0.1.1 / D44).

• New file lib/keys.mjs (~462 lines after fold-in) — public API surface:
  • createKey({ name, owner_tier, providers_enabled, notes, olpHome }) — generates opaque olp_<32-byte base64url> token (47-char total), SHA-256 hashes it for manifest storage, atomically writes keys/<id>/manifest.json (mode 0600, dir 0700). Returns { id, plaintext_token, manifest } — plaintext token is printed once and never persisted.
  • validateKey(plaintext, { allowAnonymous, olpHome }) — three-tier resolution per § 5 / § 7 / § 9.4: env override (OLP_OWNER_TOKEN → __env_owner__ synthetic identity) → anonymous (only when allowAnonymous: true, returns __anonymous__ identity) → filesystem manifest lookup (constant-time hash compare via crypto.timingSafeEqual). Revoked manifests return null (caller produces 401). Per § 6.3.5 — MUST hit manifest every request; no in-process validation cache.
  • revokeKey({ id, olpHome }) — idempotent; sets revoked_at via atomic write inside per-key write-lock.
  • listKeys({ olpHome }) — returns manifest objects with token_hash redacted.
  • touchLastUsed(id, { olpHome }) — async best-effort lazy update per § 6.3 revoke-dominates-touch: re-reads latest manifest inside the per-key lock, NO-OPs if revoked_at is non-null, otherwise merges last_used_at preserving all other fields. Failure logs warn and never throws.
• § 6.4 in-process per-key write-lock — Map<key-id, Promise> chain; serializes intra-process writes. External (CLI) writes not lock-protected at Phase 2; atomic-rename + § 6.3 read-before-write give the revoke dominates touch safety property.
• Test-only hooks — __setTouchInterleaveHook (inject deterministic pause between touch's lock acquisition and read for race tests) + __resetWriteLocks (test cleanup).
• What is NOT in D44 (split per ADR §§ 6.2 / 9.1 separation): audit ndjson append (request-layer concern; D45 server glue); keygen CLI bootstrap surface (D45+); server.mjs integration replacing the hardcoded '__anonymous__' keyId at server.mjs:502, :531 (D45); owner-vs-guest gating for /health and X-OLP-Fallback-Detail (D46).
• Test count: 468 → 496 (+28 tests in new Suite 19):
  • 19a-d token generation (§ 5)
  • 19e-j manifest write+read + chmod 0600/0700 + schema validation (§ 4, § 6.1)
  • 19k-p validateKey: filesystem / wrong / missing / anonymous / revoked / env override (§ 5, § 6.3.5, § 9.4)
  • 19q-r revokeKey idempotency + non-existent id
  • 19s-t listKeys empty + redaction
  • 19u-x touchLastUsed updates + NO-OP on revoked + NO-OP on anonymous/env identities + best-effort failure
  • 19y-1 to 19y-4 acceptance criterion #7 (concurrent revoke + touch race tests): revoke→touch, touch→revoke, interleaved external-revoke-via-hook (deterministically reproduces the § 6.3 race the maintainer's text review caught), 30-iteration concurrent-promise stress
• Documentation: AGENTS.md lib/keys.mjs 📋 marker → 🟡 "core landed at D44"; AGENTS.md Implementation-status-note + shipped-set updated to include lib/keys.mjs; README.md Implementation Status row + Known limitations "Multi-key auth" note updated to "core landed, server integration pending D45".
• Fold-in (fresh-context opus reviewer findings, 2 P2 correctness + 2 P3 polish):
  • P2 #1 lock-map cleanup (lib/keys.mjs _withKeyLock): prior version stored prev.then(() => next) as the Map tail, but the cleanup-identity check _writeLocks.get(id) === next could never match the derived promise — Map entries leaked one-per-unique-key-id. Bounded impact at family scale (~5–10 entries) but a real correctness bug. Fixed by storing next directly. New regression tests 19x-extra (sequential) + 19x-extra-2 (concurrent 3-key × 3-touch contention) assert __writeLockSize() === 0 post-drain.
  • P2 #2 validateKey non-string defensive coding: prior version threw TypeError when called with a non-string truthy plaintext (validateKey(42) / validateKey({})), reaching hashToken(<non-string>) → createHash().update(<non-string>). Q2 promised "bad inputs return null." Fixed via top-of-function if (plaintextToken != null && typeof plaintextToken !== 'string') return null;. New test 19m-extra covers number / object / array / allowAnonymous: true paths.
  • P3 #3 19y-3 test scope comment: test simulates external revoke landing BEFORE touch's read, not BETWEEN touch's read and write (which is currently unreachable because touchLastUsed has synchronous read→write — no await between readManifest and writeManifestAtomic).

D43-B — ADR 0007 multi-key auth design draft (design-only, no code change)

Phase 2 mainline design ADR. Ratifies the storage / token / manifest / atomic-write / owner-gating / bootstrap / Node-baseline decisions ahead of D44+ implementation D-days. Pure design doc — no .mjs / no tests / 4 files touched.

• docs/adr/0007-multi-key-auth.md (new, ~420 lines after fold-ins): 13 sections covering Context / Decision (Option 2 + opaque key) / Storage layout (~/.olp/keys/<key-id>/manifest.json + ~/.olp/logs/audit.ndjson) / Manifest schema (schema_version, token_hash, owner_tier, providers_enabled) / Token format (olp_<32-byte base64url>, SHA-256 hash) / Atomic write & audit append (manifest lifecycle-only atomic via tmpfile+fsync+rename; audit per-request append, warn + 1 retry, no memory buffer at Phase 2) / Owner-vs-guest-vs-anonymous gating (config.json auth.allow_anonymous default false, no env auto-detection) / Audit ndjson schema (no PII) / Bootstrap & recovery (minimal keygen command surface + OLP_OWNER_TOKEN env override with stable __env_owner__ keyId) / Acceptance criteria (11 test surfaces for D44+) / Node baseline (Option 1 SQLite port rejection rationale citing engines >=18 + CI 20/24 vs node:sqlite v22.5.0 with flag) / Out of scope (Dashboard, quota enforcement, audit query, file locking deferred to Phase 3+) / Future forward (Option 3 hybrid migration trigger + preconditions).

D43-A — Phase 2 doc alignment (no code change)

Phase 1 was closed at v0.1.1; this commit aligns documentation surfaces to the Phase 2 reality before D43-B (ADR 0007 draft) lands. Pure doc cleanup; no .mjs or test changes.

• CLAUDE.md release_kit.current_phase Phase 1 → Phase 2; current_pre_release_identifier 0.1.0-bootstrap → 0.2.0-phase2.
• README.md status header + Implementation Status + Phase plan rewritten to reflect actually-shipped reality (v0.1.0 + v0.1.1 bundled the three Tier-D plugins + cache + fallback into a single Phase 1 milestone, not one phase per plugin as the original v0.1 spec planned). lib/keys.mjs row + "Multi-key auth not yet implemented" note updated to "Phase 2 active per ADR 0007 (drafting at D43-B)".
• AGENTS.md § Key files to know — lib/keys.mjs 📋 marker updated to "Phase 2 active per ADR 0007 (drafting at D43-B)"; Implementation-status-note paragraph dated 2026-05-25 + reflects Phase 1 close + Phase 2 active scope.
• ALIGNMENT.md § Provider Inventory — added one-paragraph "Note on phase terminology" clarifying that "Phase" in the Provider Inventory tables + § One-shot Triggered Audits "OpenAI Codex ToS formal pin" refers to the original per-plugin enablement plan, orthogonal to the milestone phase numbering in README. Fold-in for D43-A reviewer P2 finding; no governance-text change, no Speculative-Candidate plugin reclassification.

v0.1.1 — 2026-05-25

Phase 1 cleanup — pre-Phase-2 batch (D35–D42, closes 16 of 17 issues)

Overview. v0.1.1 closes the post-v0.1.0 cleanup batch covering all 17 pre-Phase-2 issues raised during the 6-round cold-audit cycle on the Phase 1 deliverable. 8 D-day commits (D35–D42) shipped between 2026-05-24 and 2026-05-25. 16 issues closed; issue #16 (streaming singleflight) stays OPEN as the v1.x tracker with its design ratified in ADR 0005 Amendment 8.

Test count: 416 (v0.1.0) → 468 (v0.1.1). +52 tests across the cleanup batch.

D35 — pre-Phase-2 batch #1 (issues #4 #9 #10 #11 #12)

• #4 — X-OLP-Latency-Ms uniform. Audit confirmed already-correct via D32; D35 adds the #4-audit regression test pinning the 5-header invariant on the 503 no-provider sendError so future drift is caught immediately.
• #9 — Streaming empty-then-clean-exit headers. Zero-chunk streaming path now guards !res.headersSent and emits Content-Type=text/event-stream, Cache-Control=no-cache, Connection=keep-alive, X-Accel-Buffering=no, plus all 5 X-OLP-* headers via olpHeaders before writing SSE_DONE. Zero-chunk path correctly does NOT cache.
• #10 — Streaming post-first-chunk error truncation marker. Two sibling fixes: catch-block-firstChunkEmitted=true and error-chunk-after-first-chunk both now emit synthetic {type:'stop', finish_reason:'length'} via irChunkToOpenAISSE + SSE_DONE + res.end(). Per ADR 0004 § Fallback safety: post-first-chunk truncation surfaces as length finish, never a hang.
• #11 — validateIRRequest irVersion strict check. ADR 0003 IR contract pins irVersion to '1.0'. Validator now: obj.irVersion !== undefined && obj.irVersion !== '1.0' → rejection. Strict string match — undefined accepted (back-compat), '1.0' accepted, '2.0' rejected, numeric 1.0 rejected (1.0 !== '1.0').
• #12 — alignment.yml scripts/ trigger removal.** Removed from both push.paths and pull_request.paths since the scripts/ directory does not currently exist (planned for Phase 7).
• Test count: 416 → 424 (+8).

D36 — pre-Phase-2 batch #2 (issues #2 #5 #6 #13 #14 #15)

• #2 — cache_control partial-noop debug log. server.mjs handleChatCompletions fires logEvent('debug', 'cache_control_partial_noop', { chain, marker_count }) at most once per request when markers present AND chain has at least one non-Anthropic hop. Per ADR 0005 § D2.
• #5 — ADR 0002 vibe.mjs → mistral.mjs. § Decision filesystem layout corrected to match the shipped file naming convention (file named after provider key, not CLI binary). Amendment 5 documents the correction + makes the convention statement explicit for future contributors.
• #6 — mistral.mjs A5 flip + ALIGNMENT.md table update. Header A5 (model flag) flipped from UNPINNED-D-later-verifies to CONFIRMED-NOT-APPLICABLE with DeepWiki citation; ALIGNMENT.md Speculative-Candidate table mistral row updated to remove A5.
• #13 — /v1/models alias governance. ALIGNMENT.md gains "Controlled deviations (entry-surface scope)" subsection documenting the alias surface as a controlled Rule 2(b) deviation; docs/openai-spec-pin.md gains the alias-surfacing subsection with full 4-field contract table.
• #14 — cache_control slot determinism regression test. 4 tests in test-features.mjs construct hand-built IRs with synthetic markers (bypassing openAIToIR which strips them at v0.1) and verify the cache key SHA-256 is deterministic. Per ALIGNMENT.md Rule 2 (No Invention), no sortMarkers helper shipped — the slot is dead-code at v0.1.
• #15 — Anthropic v2.1.89 transcript artifact. New file docs/provider-audits/anthropic.md as a single living version-capture artifact. Records observed claude --version (2.1.132 at capture date 2026-05-24), pinned version (v2.1.89 from D4), drift note, sample invocation, flag-surface table for 5 OLP-consumed flags. Closes the circular ALIGNMENT.md ↔ plugin header citation by anchoring on an external artifact.
• Test count: 424 → 431 (+7).

D37 — release.yml phase_rolling_mode gate (issue #17)

• CI gate enforcing phase_rolling_mode promotion discipline. New "Enforce phase_rolling_mode (Unreleased must be promoted)" step in release.yml between the version-match check and the CHANGELOG extraction step. Awk extracts content between ## Unreleased and the next ## heading; sed strips blank lines and parenthetical-sentinel-only lines. Non-trivial remaining content fails the workflow with ::error:: instructing the maintainer to promote Unreleased → ## v<version> per CLAUDE.md release_kit.phase_rolling_mode.
• Dry-run validated against 4 cases: current sentinel-only Unreleased → PASS; synthetic non-trivial Unreleased → FIRES with offending lines reported; no Unreleased section → PASS; multi-sentinel + blank lines → PASS.
• Gate is purely additive — fires only on tag push to v*.*.*, does not affect normal push/PR CI.
• Test count: 431 → 431 (no test change — CI workflow only).

D38 — maxConcurrent runtime enforcement (issue #1)

• Spawn lifecycle gate — hints.maxConcurrent is now enforced at runtime per ADR 0002 Amendment 6: lib/providers/index.mjs exports a per-provider tryAcquireSpawn / releaseSpawn / getActiveSpawnCount semaphore; server.mjs gates both the buffered and streaming spawn call sites in handleChatCompletions with a try/finally release. Saturation surfaces as ProviderError(CONCURRENCY_LIMIT) which the fallback engine treats as a hard trigger (ADR 0004 Amendment 4) — the chain advances to the next hop instead of queueing. If the entire chain is saturated, the user receives a chain-exhausted error via the existing exhaustion path. Closes #1. Queue+timeout deferred (see ADR 0002 Amendment 6 § Design choice). Test count 431 → 447.

Test count 431 → 447.

D39 — D16 follow-ups (issue #3): explicit cache delete + eviction log + SPAWN_TIMEOUT asymmetry doc

• Part 1 — CacheStore.delete(keyId, cacheKey) — adds an explicit eviction primitive to lib/cache/store.mjs. Returns boolean (true if entry present and removed; false otherwise) and removes empty per-keyId namespace Map entries from the outer store for memory hygiene (matches the D38 _activeSpawns pattern). server.mjs D16 salvage path replaces cacheStore.set(..., ttlMs=0) (lazy tombstone that lived in the namespace Map until the next get/peek purged it) with cacheStore.delete(...) (immediate removal). Cache semantics unchanged — truncated responses still don't persist. ADR 0005 § "Cache write conditions" item 1 authority.
• Part 2 — cache_evicted_truncated observability log — adds an info-level structured log event fired immediately after the D16 eviction in executeHopFn. Carries { provider, model } so dashboards can surface salvage frequency per (provider, model) pair. P3 polish; no semantic change.
• Part 3 — sticky-cache regression test — defense-in-depth test asserting two consecutive identical buffered requests that both trigger SPAWN_FAILED-with-chunks salvage each invoke a fresh spawn (spawnCount=2 across the two requests; second request reports X-OLP-Cache: miss). Catches any future regression where the eviction is dropped or the gate condition flips.
• Part 4 — SPAWN_TIMEOUT salvage asymmetry documented (no code change) — ADR 0004 Amendment 1 gains a new sub-section "Why SPAWN_TIMEOUT is excluded from salvage" with a 4-point rationale: (1) SPAWN_FAILED is a terminal signal, SPAWN_TIMEOUT is a deadline signal; (2) the next hop is a different provider with different speed characteristics, plausibly full-response-soon-after-T; (3) the "user paid for partial" framing applies to SPAWN_FAILED only — for SPAWN_TIMEOUT the user paid for "result within T"; (4) code inspection confirms the catch block matches only code === 'SPAWN_FAILED'. Includes hard-trigger-taxonomy completeness note and v1.x re-evaluation trigger (opt-in salvage-on-timeout for long deadlines).
• Authority: ADR 0005 § Cache layer / CacheStore API extension (Part 1); ADR 0004 Amendment 1 (Part 4); GitHub issue #3 — closed by this commit; D16 commit bafa6d1 non-blocking suggestions — batched here.
• Test count: 447 → 452 (3 unit tests for CacheStore.delete + 1 log-event integration test + 1 sticky-cache regression test).

D40 — X-OLP-Fallback-Detail header (issue #7)

• New debug header on responses with a non-empty failure trail — lib/fallback/engine.mjs#executeWithFallback now returns a fallbackDetail array of per-hop tuples on every code path. server.mjs emits X-OLP-Fallback-Detail: <JSON-stringified array> on any response where at least one hop failed before the chain resolved or exhausted (chain-exhausted, non-trigger-error, client-error, AUTH_MISSING, and success-with-prior-failure paths). Header is absent on clean primary success (no failure trail to report).
• Tuple schema — { hop, provider, model, code, error_message, trigger_type } per failed hop. code is the ProviderError code or 'UNKNOWN' for non-ProviderError exceptions; error_message is truncated to 200 chars with a U+2026 ellipsis on truncation; trigger_type matches D28's classifyTrigger output ('hard' / 'soft' / 'auth_missing' / 'client_error' / 'non_trigger'). Field shapes reuse D28's per-hop structured log event keys so logs and the header pivot on the same surface.
• 4KB UTF-8 byte cap — if the JSON-stringified array exceeds 4096 bytes, tail tuples are dropped and a { truncated: true, omitted_hops: N } sentinel is appended such that the total fits under the cap. Cap calculation uses Buffer.byteLength('utf8'), not string length.
• RFC 7230 hygiene — non-ASCII code points (e.g. the em dash in the D38 CONCURRENCY_LIMIT synthesised error message) are escaped as \uXXXX so the header value is pure ASCII. Node's HTTP header validator rejects multi-byte UTF-8 in field values; without this step, em-dash-bearing error messages would crash res.writeHead. JSON.parse round-trips the escaped form correctly.
• Gating posture — ungated at v0.1 — the original ADR 0004 § Chain advancement step 4 specified owner-only gating. Per the maintainer decision in issue #7, v0.1 ships the header ungated (single-tenant family-scale per ALIGNMENT.md; no PII risk in error details). Phase 2 will re-introduce owner-vs-non-owner gating when lib/keys.mjs lands — explicit follow-up tracked in AGENTS.md § Key files to know and ADR 0004 Amendment 5.
• Authority: ADR 0004 § Decision § Chain advancement step 4 (original promise — D40 fulfils it); ADR 0004 Amendment 5 (D40 ratification); D18 (5 standard X-OLP-* headers; D40 builds on the convention); D28 (per-hop structured log fields; D40 reuses the field shapes); GitHub issue #7 — closed by this commit.
• Test count: 452 → 468 (7 engine-level tuple-shape tests + 6 serialiser unit tests including the 4KB cap + non-ASCII regression + 3 HTTP integration tests).

D41 — X-OLP-Provider-Used semantics documented (issue #8)

• Doc-only clarification. On a chain-exhausted response, X-OLP-Provider-Used identifies the chain's configured primary entry (chain[0].provider), not necessarily the first hop where spawn() was actually invoked. At v0.1 this is unobservable because soft triggers are deferred (ADR 0004 Amendment 2) — every hop is attempted in order, so chain-origin and first-attempted are equivalent. When soft triggers reactivate in v1.x, a soft-skipped hop 0 followed by hard-failed hops 1+N would still report providerUsed=chain[0] despite chain[0] never being spawned.
• Option B (document chain-origin) chosen over Option A (track firstAttemptedProvider). Rationale: Option A would add state to executeWithFallback for an unreachable v0.1 code path (ALIGNMENT.md Rule 2 — No Invention). The D40 X-OLP-Fallback-Detail header already carries precise per-hop spawn history (including soft-skip records with trigger_type: 'soft'), so the disambiguation channel exists on the wire without needing providerUsed to handle it.
• Updates: ADR 0004 Amendment 6 documents the semantics; README.md § Observability headers replaces "which provider's plugin served the request" with the chain-origin wording; lib/fallback/engine.mjs chain-exhausted return site gains an inline comment citing the amendment and the v1.x re-evaluation note.
• No code-behavior change. No new tests — the relevant scenario is dead-by-config at v0.1; the v1.x soft-trigger reactivation work should add a test that exercises the soft-skip + chain-exhausted edge case and pins whichever option the v1.x maintainer chooses (the amendment names Option A as the likely v1.x preference).
• Authority: ADR 0004 Amendment 6 (this commit); ADR 0004 § Decision § Chain advancement step 4; ADR 0004 Amendment 2 (soft triggers deferred — precondition); ADR 0004 Amendment 5 (per-hop attribution channel via X-OLP-Fallback-Detail); ALIGNMENT.md Rule 2 (No Invention rationale); GitHub issue #8 — closed by this commit.
• Test count: 468 → 468 (no test change).

D42 — Streaming singleflight design ADR + v1.x roadmap (issue #16)

• Design-only ratification of the v1.x streaming singleflight implementation. ADR 0005 Amendment 6 (D34) had deferred this work with a "design alone warrants a dedicated ADR" note. D42 fulfils the note as ADR 0005 Amendment 8, ratifying the cacheStore.getOrComputeStreaming(...) API shape, per-(keyId, cacheKey) inflight Map, tee fan-out with bounded per-client backpressure queues, late-joiner replay buffer, AbortController propagation on all-disconnect, D38 tryAcquireSpawn coordination (only the first caller's spawn counts against the semaphore), cache TTL race handling, the new STREAM_BACKPRESSURE error code (NOT a hard trigger), and the new X-OLP-Streaming-Inflight: source | attached | solo header. Implementation acceptance criteria are enumerated in Amendment 8 §13.
• Multi-layer safeguards to ensure the v1.x work is not forgotten. New file docs/v1x-roadmap.md is a single living landing page for every Phase-1 deferral (streaming SF, multi-key auth, soft-trigger reactivation, /health activeSpawns, provider-level cacheKeyFields, streaming-path SPAWN_FAILED salvage, D40 AUTH_MISSING tuple test). Each entry names the ratifying ADR, the load-bearing code anchor, and a concrete trigger to start. Cross-references added at: lib/cache/store.mjs#getOrCompute JSDoc (sibling API TODO), server.mjs streaming-branch entry (~line 810, the peek+spawn pattern Amendment 8 replaces), README.md § Known limitations (user-facing surface), and docs/adr/0005-cache-cross-provider.md Amendment 8 § "Cross-references and safeguards".
• Issue #16 status. STAYS OPEN as the v1.x implementation tracker. The body of the issue is updated post-D42 to reference Amendment 8 and clarify scope ("design ratified; implementation pending"). DO NOT close the issue until Amendment 8 §13's test surface is green against an actual implementation.
• No code-behavior change. No new tests. Amendment 8 is design-only. The implementation will go through full Iron Rule 10 (fresh-context opus reviewer + acceptance-criteria-gated test pass) when the v1.x sprint kicks off.
• Authority: ADR 0005 Amendment 8 (this commit); ADR 0005 Amendment 6 (D34 — original deferral note); GitHub issue #16 (round-6 F13 — sibling TOCTOU); ADR 0002 Amendment 6 (D38 — tryAcquireSpawn semantics that §7 coordination builds on); ADR 0004 Amendment 5 (D40 — observability pattern §11 extends); CLAUDE.md release_kit_overlay phase_rolling_mode — under Unreleased; CC 开发铁律 v1.6 § 10.x (design-only amendment; fresh-context reviewer not required per the Iron Rule 10 implementation-phase scope, documented in the amendment's procedural mechanism).
• Test count: 468 → 468 (no test change — design-only).

v0.1.0 — 2026-05-24

Phase 1 Close — Multi-provider proxy core

Overview. Phase 1 delivers the OLP minimum-viable multi-provider proxy: OpenAI-compatible HTTP entry surface, plugin architecture for 3 Tier-D providers (Anthropic Claude / OpenAI Codex / Mistral Vibe), cache layer (D1 per-key isolation + D4 buffered-path singleflight + size cap + cacheable opt-out), fallback engine with first-chunk safety + spawn-timeout hard trigger + structured per-hop log observability, IR↔OpenAI translation honoring the Rule 2(b) no-invention constraint, and a 416-test suite covering all of it.

Released under phase_rolling_mode (CLAUDE.md release_kit overlay): 25 D-day commits accumulated on main between 2026-05-23 and 2026-05-24 before this version bump + tag.

Provider posture. Three Tier D plugins ship as Candidate (per ALIGNMENT.md § Provider Inventory) — runnable via providers.enabled config but not Enabled by default. Five additional Tier B/C plugin slots exist in models-registry.json as Speculative-Candidate / candidate stubs awaiting CLI authority pins. Zero Enabled providers at v0.1; transition to Enabled requires Phase audit + primary-source pin per ADR 0002.

What landed (D10–D34 commit index)

The per-commit detail is in the git log; this index summarizes the deliverables.

Phase 1 core hardening:

• D10 (2cfd0b1) — P1 round-3: providers.enabled config wiring + real SSE streaming on single-hop cache-miss + spawn-timeout hard trigger across all 3 plugins.

Round-1 fold-in batch (cold audit caught 17 findings):

• D11 (f659e29) — ADR 0002 Amendment 1: maxSpawnTimeMs ratified into Provider contract hints.
• D12 (4b1a9c8) — IR translator Rule 2(b) compliance: removed invented top-level error field on chat.completion shapes.
• D13 (f34b690) — Per-hop cache_control bypass evaluation (was request-global).
• D14 (a7085d9) — Defer res.writeHead(200) until first chunk; early-error returns 502 JSON instead of 200 empty SSE.
• D15 (8ae77c3) — ADR 0005 Amendment 2: cache key includes max_tokens / top_p / stop / tool_choice.
• D16 (bafa6d1) — ADR 0004 Amendment 1: SPAWN_FAILED-with-chunks salvage (don't discard partial responses).
• D17 (cb86807) — Alias routing SPOT via models-registry.json; getProviderForModel canonicalizes.
• D18 (82ff007) — /v1/models populated from registry; 5 standard X-OLP-* headers on error responses.
• D19 (ed82e65) — Cleanup batch: finish_reason validator, dead alignment.yml KNOWN_PROVIDERS removal, unused imports.

Test growth

277 (pre-D10) → 416 (post-D34). 6 cold audit rounds reviewed code against ADR claims. Iron Rule v1.6 § 10.x dual-mode review discipline (Diff Review + Cold Audit) caught 78+ findings of which ~50 closed via implementation and ~28 deferred to GitHub issues.

Known limitations carried to v1.x

17 GitHub issues filed for follow-up. Notably:

• Streaming singleflight (#16) — multi-concurrent identical streaming requests each spawn fresh CLI; buffered path participates in D4, streaming path doesn't (deferred via ADR 0005 Amendment 6).
• maxConcurrent runtime enforcement (#1) — declarative-only at v0.1.
• X-OLP-Fallback-Detail debug header (#7) — documented in ADR 0004, never emitted.
• Soft triggers (per ADR 0004 Amendment 2) — evaluation code exists but quotaStatus() polling not wired; configured thresholds inert at v0.1.

Migration from OCP

OLP supersedes OCP per ADR 0001. The scripts/migrate-from-ocp.mjs migration tool is 📋 Planned (Phase 7).

v0.1.0-bootstrap — 2026-05-23

Phase 0 — Repo bootstrap (founding + post-codex-review hardening)

This is the founding commit set of OLP (Open LLM Proxy), a personal- and family-scale multi-provider LLM proxy that supersedes OCP. The trigger was Anthropic's 2026-05-14 announcement (effective 2026-06-15) splitting claude -p / Agent SDK / third-party agent traffic out of the Pro/Max subscription pool into a separate fixed monthly Agent SDK Credit pool.

What lands at v0.1.0-bootstrap (final state on main as of 2026-05-23):

• ALIGNMENT.md — OLP constitution. Three concurrent authorities (per-provider CLI / OpenAI spec / IR contract), 5 Rules, 4-tier Risk Tier Framework, Candidate-vs-Enabled provider inventory, one-shot triggered audits (2026-06-16 Anthropic post-split; 90-day Antigravity primary-source pin).
• AGENTS.md — multi-tool agent guidelines (inherits ~/.cc-rules/AGENTS.md).
• CLAUDE.md — Claude-Code-specific session instructions + machine-readable release_kit overlay (Iron Rule 5.5).
• README.md — phase-aware skeleton with Candidate-vs-Enabled provider tables, API endpoint table, environment-variables table, response-headers spec, architecture overview, phase plan, migration-from-OCP outline. Placeholder content marked as such per phase.
• docs/adr/ — 6 founding ADRs:
  • 0001-project-founding.md — Mission, non-mission, narrow-scope supersession of OCP ADR 0005 (single-provider-sufficiency premise only; BYOK / no-spawn parts of ADR 0005 not inherited).
  • 0002-plugin-architecture.md — lib/providers/<name>.mjs plug-in model with the Provider contract (name / models / auth / spawn / estimateCost / quotaStatus / healthCheck / hints). 8 candidate providers declared, 0 Enabled at v0.1.
  • 0003-intermediate-representation.md — OLP-internal canonical IR between OpenAI-compat entry and provider plugins.
  • 0004-fallback-engine.md — Trigger taxonomy (Hard / Soft / Deterministic-deferred / Cost-aware-deferred), idempotent-failure safety (first-chunk rule), chain advancement one-at-a-time, observability headers.
  • 0005-cache-cross-provider.md — Cache key composition over (provider, model, messages, ...), D1+D2+D3+D4 port from OCP v3.13.0.
  • 0006-provider-inclusion.md — 4-tier Risk Framework, Candidate-vs-Enabled distinction, 8-provider candidate classification, Antigravity Tier A (evidence-backed, pending primary-source pin) — exclusion rests on (named prohibition + no cost advantage + reinstatement friction) combination; primary-source URL not yet pinned, follow-up tracked.
• .github/PULL_REQUEST_TEMPLATE.md — 8-radio Change Type taxonomy + per-type Authority Evidence sections + Iron Rule 10 reviewer checklist.
• .github/workflows/alignment.yml — CI blacklist (transitive api.anthropic.com/api/oauth/usage from OCP 2026-04-11 drift; Antigravity provider exclusion enforcement) + models-registry.json validator + commit-citation soft check (process-substitution form, no Bash subshell trap).
• .github/workflows/release.yml — Auto-release on tag push with package.json-vs-tag version match check (Iron Rule 5).
• .github/workflows/test.yml — Node 20/24 matrix; tolerates bootstrap-phase absence of test-features.mjs AND scripts.test.
• models-registry.json — minimal v0.1 stub with empty providers: {}, matching the 0-Enabled posture; populated by Phase audits as providers transition Candidate → Enabled.
• package.json — minimal: no main, no scripts.test, no scripts.start (those entries land alongside the real files in Phase 1).
• .gitignore, LICENSE (MIT), CHANGELOG.md — standard project boilerplate.

Provider posture at v0.1.0-bootstrap (per ALIGNMENT.md § Provider Inventory):

Tier	Anticipated providers	v0.1 default state
D (eligible-for-default-enabled)	Anthropic, OpenAI Codex, Mistral Vibe	Candidate (transition gate: authority pin + plugin + Phase audit)
C (opt-in)	xAI Grok, Moonshot Kimi	Candidate
B (opt-in + consent)	MiniMax, Zhipu GLM, Alibaba Qwen	Candidate
A (excluded by default; constitutional-amendment-only re-inclusion)	Google Antigravity	Excluded; pending primary-source pin

Total Enabled at v0.1.0-bootstrap: 0. Enablement is a Phase audit deliverable, not a bootstrap claim. This explicit zero is intentional and codified — a constitution that names providers as "default-enabled" while their CLI versions, output shapes, auth artifacts, and exit-code semantics are still TBD would violate Rules 1 (Cite First) and 3 (Match the Implementation).

Review history for this version:

1. Initial internal review (Claude Opus, fresh-context, Iron Rule 10). Verdict: APPROVE_WITH_MINOR — 2 minor items (alignment.yml heredoc indent breaking bash parse on failure path; AGENTS.md cross-reference to ADR 0003 imprecise). Both folded in before the founding commit.

2. External review #1 (OpenAI Codex CLI, no spec framing). Verdict: 6 substantive findings beyond internal review.

   • Provider Inventory split into Candidate vs Enabled (the v0.1 constitution had declared anthropic / openai / mistral as Tier D default-enabled while their Authority pins were still TBD at Phase N spawn — direct violation of Rule 1 / Rule 3 against the constitution's own text).
   • Antigravity Tier A downgraded to "evidence-backed, pending primary-source pin" (secondary reports disagree on blast radius; Google FAQ URL not yet primary-source-pinned).
   • ADR 0001 supersession scope narrowed (OLP rejects ADR 0005's "BYOK + no spawn" qualifiers, which originally applied to a commercial pivot; OLP is non-commercial and spawn-binary by design).
   • Anthropic post-2026-06-15 one-shot audit scheduled (annual May 14 audit would leave Anthropic re-eval ~year late after the split takes effect).
   • Tier A "permanent" language unified across docs (constitution and ADR 0006 had disagreed).
   • OpenAI Tier D wording softened ("maintainer signal indicates low risk; formal ToS pin pending" — Discussion #8338 is a posture statement, not a formal ToS blessing).

3. External review #2 (OpenAI Codex CLI, second pass after review #1 fold-in). Verdict: 6 additional substantive findings — the self-consistency trap recurred when fold-in of review #1 was scoped only to files codex explicitly named. Round #2 caught:

   • ADR 0002 still claimed "three default-enabled" while ALIGNMENT.md said zero Enabled — accepted ADR contradicting constitution.
   • release.yml would publish stale ## v0.1.0-bootstrap notes that ignored the "Unreleased" amendments — fixed by consolidating amendments into the v0.1.0-bootstrap section (this entry).
   • package.json advertised main / scripts.test / scripts.start for files that don't exist — npm test / npm start failed locally. Removed all three; will return in Phase 1 alongside the real files.
   • models-registry.json documented as SPOT but missing — minimal stub added.
   • alignment.yml commit-citation soft check had a Bash subshell trap (while in pipe loses WARN=1 mutation) — fixed via process substitution < <(...).
   • Tier A "permanent" wording still inconsistent across alignment.yml workflow text, ADR 0006 Consequences section, and the rest of the docs — unified throughout.

   All 6 round-#2 findings folded in this consolidated v0.1.0-bootstrap state.

Reviewer framing learning (recorded permanently in ~/.cc-rules/memory/learnings/ai_reviewer_self_consistency_trap.md): Internal AI reviewers framed on a shared source-of-truth miss bugs in the source-of-truth itself. The self-consistency trap recurred during the fold-in of round #1 — when an external reviewer surfaces findings, the fold-in must grep the entire repo for the same concept, not only edit the files the reviewer named. Round #2 caught what round #1's fold-in missed for exactly this reason. Both lessons updated in the cross-machine memory.

Iron Rule 10 status: Satisfied. Initial reviewer = internal opus (independent from drafters). Round #1 reviewer = external codex (independent from drafters and from internal opus). Round #2 reviewer = external codex (independent from the round #1 fold-in implementer). The maintainer's role across all three reviews was approver, not author. The drafting agents and fold-in agents were never the same as the reviewers for any of the three passes.

Next: Phase 1 lands server.mjs skeleton + IR + Anthropic provider plugin + cache D1+D4 port from OCP. At that point, package.json regains main + scripts.test + scripts.start, test-features.mjs lands, models-registry.json populates its first providers.anthropic entry, and Anthropic transitions Candidate → Enabled. Per spec §6 phase plan.
