release(v0.5.1): hotfix — quota probe cache/backoff/schema-drift correctness (codex review) (#58)

* release(v0.5.1): hotfix — quota probe cache/backoff/schema-drift correctness (codex review)

Addresses three production-quality findings from codex's post-v0.5.0 review (codex review on
PR #57, reproduced with local mocks):

F1 [P1] — Doctor bypass of cache + backoff (ADR 0013 Rule 3)
  `anthropic.quota_probe_reachable` called `_probeOnce(auth)` directly, bypassing
  `quotaProbeState.backoffUntil`. Successive `olp doctor` invocations within a backoff
  window each hit upstream — violating ADR 0013 Rule 3 (backoff is mandatory for ALL
  consumers). Fix: doctor now routes through `quotaStatus()`. ADR 0013 Rule 3 clarified:
  "All consumers of `quotaStatus()`, including `olp doctor` checks, MUST route through
  `quotaStatus()` and MUST NOT call `_probeOnce()` directly."

F2 [P2] — 200 with empty ratelimit headers cached as live data (ADR 0013 Rule 5)
  A 200 OK with zero `anthropic-ratelimit-*` headers was cached as `stale: false` (live).
  Minimum-viable-schema gate added to `_probeOnce`: requires 5h-utilization + 5h-reset +
  7d-utilization + 7d-reset present; absence → `failureKind: 'schema_drift'`, backoff
  scheduled, result NOT cached. ADR 0013 Rule 5 updated with the gate specification.

F3 [P2] — Dashboard-data loses failure detail (ADR 0013 Rule 6)
  `aggregateProviderQuota()` collapsed all failure modes into `status: 'unavailable'`
  ("no public quota api or probe disabled") — same as providers with no API at all.
  Fix: `quotaStatus()` v0.5.1 contract — `null` ONLY for opt-in-off; failures return
  `{ probe_status: 'unreachable', failure: { kind, message, backoff_until? } }`.
  New `failure_kind` enum: no_credentials | auth_failed | rate_limited | schema_drift |
  network | other. Dashboard renders `unreachable` with red border + failure detail.

Authority:
  ADR 0013 Rules 3, 5, 6 (cache + backoff + schema-drift + failure transparency)
  ADR 0008 Amendment 2 (richer quota_v2 shape; new unreachable status)
  ADR 0002 Amendment 8 unchanged (constitutional permission for the probe)
  Codex review findings F1–F3 (codex on PR #57)

Changes:
  - lib/providers/anthropic.mjs: quotaProbeState gains lastError + failureKind;
    _probeOnce: min-field gate + failureKind population; quotaStatus(): v0.5.1 contract
    (null=disabled only; probe_status:live/stale/unreachable); doctorChecks routes
    through quotaStatus(); reset functions updated
  - lib/audit-query.mjs: _normalizeAnthropicQuota handles probe_status field;
    aggregateProviderQuota emits failure/failure_kind/backoff_until; unreachable status
  - dashboard.html: unreachable CSS classes + render path + footer v0.5.1
  - test-features.mjs: 38f/j/l updated for v0.5.1 shape; 38r refactored for F1;
    38g/k gain probe_status assertions; 38u/v/w new regression tests; 756→759 tests
  - docs/adr/0008: Amendment 2 (richer ProviderQuotaEntry + quotaStatus contract)
  - docs/adr/0013: Rule 3 clarification (doctor must use quotaStatus);
    Rule 5 min-viable-schema gate specification
  - package.json: 0.5.0 → 0.5.1
  - CHANGELOG.md: v0.5.1 hotfix entry promoted from Unreleased
  - README.md / AGENTS.md: Phase 5 closed at v0.5.1; Phase 6 next

* docs+code: PR #58 fold-in — reviewer Nits #1 + #2 (ADR doc-drift + opt_in_off enum)

Fresh-context reviewer (PR #58) verdict: APPROVE_WITH_MINOR, 0 blocking,
4 nits. Folding in #1 + #2 (both 1-line cosmetic-but-correct fixes).
Deferring #3 (test-only edge case in module-level seam restore) and #4
(pre-existing codex F4 — bin/olp.mjs + olp-plugin still read legacy
quota shape; separate PR planned).

Nit #1 — ADR 0002 Amendment 8 documentation drift.

Amendment 8 at v0.5.0 line 20 said "the function returns `null` rather
than throwing", and line 33 said "stale-cache-on-failure (`null` is
returned only when no cache entry exists; if a stale entry exists it's
returned with a `stale: true` marker)". v0.5.1 refined this contract:
`null` is now reserved STRICTLY for opt-in-off, and all failure modes
return `{ probe_status: 'unreachable' | 'stale', failure: {...} }`.

The substantive idempotent-failure constraint (no throw to caller) is
unchanged. The operational description in Amendment 8 was stale — fixed
to cross-reference ADR 0008 Amendment 2 + ADR 0013 Rule 6 for the
v0.5.1 contract refinement. Also references Suite 38 (38u/38v/38w) as
the regression coverage producing the new shape.

Nit #2 — `failureKind: 'opt_in_off'` declared but never produced.

The enum value was listed in both the code comment (anthropic.mjs:250)
and ADR 0008 Amendment 2 (line 30) but never actually assigned —
because when opt-in is off, `quotaStatus()` returns the literal `null`
BEFORE any state mutation happens. The enum value was dead.

Fix: removed `opt_in_off` from both enum declarations + added an
inline note explaining that consumers (audit-query, doctor) distinguish
opt-in-off by checking `quotaStatus() === null`, not via failureKind.

Deferred:

- Nit #3 (test-seam restore edge case): if a caller pre-sets
  `_quotaAuthReadFnForTest` AND passes a non-default `_authReadFn`,
  the finally block restores to null clobbering pre-set value.
  Test-only impact, no production risk. Pure hygiene; defer.

- Nit #4 (codex F4): bin/olp.mjs cmdUsage and olp-plugin/index.js
  still read legacy `body.quota` field, never consume `quota_v2`.
  Reviewer confirmed neither crashes — both gracefully fall through
  to "no quota api" branch. Out of scope for this hotfix per the
  hotfix dispatch contract; separate PR will migrate them.

Tests: 759/759 still pass post-fold-in. No test changes needed.

Authority: PR #58 review thread + ADR 0013 Rule 6 (failure transparency)
+ ADR 0008 Amendment 2 (ProviderQuotaEntry v0.5.1 shape).

+### 1. Anthropic plan-usage probe via direct `/v1/messages` call (Phase 5, D79 — 2026-05-26)
+
+**Class:** Rule 2(a) — provider-plugin scope. The Anthropic plugin's `quotaStatus()` calls `POST https://api.anthropic.com/v1/messages` directly rather than spawning `claude -p`. Under the strict reading of Rule 2(a), plugins must mirror provider-CLI behaviour; under the strict reading, this is a deviation because the spawn path goes through the CLI binary and the probe path does not.
+
+**Authority:** ADR 0002 Amendment 8 (governance) + ADR 0013 (implementation discipline) + ADR 0012 (Phase 5 charter). Schema pin: `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md` (compiled-binary `strings` + live API probe evidence). PR #50.
+
+**Rationale:** Claude Code's compiled binary makes the same `POST /v1/messages` call internally (verified by `strings` over the v2.1.142 / v2.1.150 Mach-O / ELF binary). The probe mirrors that observed CLI behaviour without introducing a new wire format or output assumption. The exemption is bounded by ADR 0002 Amendment 8's three constraints (READ-ONLY, subscription-scope, idempotent-failure) + ADR 0013's seven implementation rules (notably Rule 2's per-endpoint enumeration — only `POST /v1/messages` is permitted).
+
+**Reviewer:** fresh-context opus subagent on PR #50 (Iron Rule 10 + CLAUDE.md hard requirement #3). Verdict: APPROVE_WITH_MINOR. Six in-PR nits folded in; three outside-PR nits documented and addressed (this entry is one of them — N9).
+
+**Re-evaluation trigger:** if Anthropic publishes a public documented quota endpoint (e.g. `GET /v1/usage`), this exception is RETIRED and the plugin migrates to the documented endpoint, deleting this exception by amendment PR. Until that hypothetical retirement, this exception is the canonical entry.

+## v0.5.1 — 2026-05-27
+
+**Hotfix — Quota probe cache/backoff/schema-drift correctness (codex review findings F1–F3).** Three production-quality bugs in the v0.5.0 quota probe, reproduced by codex with local mocks, are corrected. 756 → 759 tests (3 new regression tests); 4 existing test assertions updated to reflect the v0.5.1 return-shape contract.
+
+### Fixes
+
+- **F1 [P1] — Doctor bypass of cache + backoff (ADR 0013 Rule 3).** `anthropic.quota_probe_reachable` doctor check called `_probeOnce(auth)` directly, bypassing the module-level `quotaProbeState.backoffUntil` check. Successive `olp doctor` invocations within a backoff window each hit upstream — violating ADR 0013 Rule 3 (60s-3600s exponential backoff is mandatory for all consumers). **Fix:** doctor check now routes through `quotaStatus()`, which enforces cache + backoff. ADR 0013 Rule 3 clarification added: "All consumers of `quotaStatus()`, including `olp doctor` checks, MUST route through `quotaStatus()` and MUST NOT call `_probeOnce()` directly."
+
+- **F2 [P2] — 200 with empty `anthropic-ratelimit-*` headers cached as live data (ADR 0013 Rule 5).** `_probeOnce` treated any 200 OK (regardless of header content) as a successful probe, caching it with `stale: false` even when zero `anthropic-ratelimit-*` headers were present. A proxy stripping headers, a schema change, or a mock returning `{}` would silently appear as "LIVE" on the dashboard with all bars empty. **Fix:** minimum-viable-schema gate requires these 4 fields non-null: `5h-utilization`, `5h-reset`, `7d-utilization`, `7d-reset`. Any absence → `failureKind: 'schema_drift'`, backoff scheduled, result not cached. ADR 0013 Rule 5 updated with the gate specification.
+
+- **F3 [P2] — Dashboard-data loses failure detail (ADR 0013 Rule 6).** `aggregateProviderQuota()` collapsed all non-null failure modes (no credentials, auth failure, rate limit, schema drift, network error) into `status: 'unavailable', reason: 'no public quota api or probe disabled'` — the same string as providers with no quota API at all. Operator could not tell what to fix. **Fix:** `quotaStatus()` v0.5.1 return contract: `null` reserved for opt-in-off only; probe failures return `{ probe_status: 'unreachable', failure: { kind, message, backoff_until? } }`. `aggregateProviderQuota()` emits new fields `failure_kind`, `failure`, `backoff_until` per row. `status: 'unreachable'` distinguishes "probe failed" from `status: 'unavailable'` ("no API or disabled"). Dashboard renders `unreachable` with a red border + failure.message + backoff countdown.
+
+### Backwards-compat notes
+
+- `quotaStatus()`: `stale: false` → now also includes `probe_status: 'live'` (additive). `stale: true` → now also includes `probe_status: 'stale'` + `failure: {...}` (additive). `null` → NOW RESERVED FOR OPT-IN-OFF ONLY (breaking for callers that relied on `null` to detect "no credentials" or "probe failed" — use `probe_status: 'unreachable'` instead).
+- `ProviderQuotaEntry.status`: gains `'unreachable'` as a new value (additive). Existing `'live'`, `'stale'`, `'unavailable'` semantics unchanged.
+- `ProviderQuotaEntry` gains new fields `failure`, `failure_kind`, `backoff_until` (additive, null when not applicable).
+- `dashboard.html`: handles `unreachable` row (no existing row had this status; additive render path).
+
+### Test changes
+
+- 38f, 38j, 38l: updated assertions from `null` to `probe_status: 'unreachable'` (F3 shape change).
+- 38r: refactored to seed cache + manually expire it + set backoff (F1 — doctor now routes through `quotaStatus()`). Added F1-regression assertion: HTTP call counter stays at 1 after two doctor calls within backoff.
+- 38g, 38k: added `probe_status` + `failure` assertions (verify new fields present on live/stale shapes).
+- **38u** (new): F1 regression — successive doctor calls within backoff window → HTTP counter stays at 1.
+- **38v** (new): F2 regression — 200 + empty ratelimit headers → `probe_status: 'unreachable'` + `failure_kind: 'schema_drift'` + cache stays null.
+- **38w** (new): F3 regression — `lastError` + `failureKind` propagate through `quotaStatus()` shape for all failure modes (rate_limited / auth_failed / schema_drift / no_credentials).
+
+### ADR changes
+
+- **ADR 0013 Rule 3** clarification: doctor checks route through `quotaStatus()`, not `_probeOnce()` directly.
+- **ADR 0013 Rule 5** update: minimum-viable-schema gate specification (4 required fields; absence = schema_drift signal).
+- **ADR 0008 Amendment 2**: richer `ProviderQuotaEntry` shape with `failure`/`failure_kind`/`backoff_until`; `probe_status` on `quotaStatus()` return; `unreachable` status semantics; `dashboard.html` unreachable rendering.

+---
+
+## v0.5.0 — 2026-05-26
+
+**Phase 5 — Provider Quota Probes + Dashboard Enrichment.** OLP gains live subscription-quota observability for Anthropic Pro/Max subscribers, surfaced through a Claude.ai-style Plan Usage panel on the owner-only dashboard. The probe is opt-in, READ-ONLY, idempotent on failure, and 5-min-cached with 60s→3600s exponential backoff. Six D-days, seven PRs, zero blocking reviewer findings, no flaky tests; 720 → 756 total tests.
+
+### What's new for users
+
+- **Live plan usage on the dashboard.** Per-provider rows show 5-hour + 7-day utilization bars with reset countdowns ("Resets in 1hr 6min" / "Resets Sun 9:00 PM"), status badges (allowed / rejected), representative-claim chips ("five_hour" / "seven_day"), overage-status indicators, and a `↻ Refresh` button. 60-second auto-refresh pauses when the tab is hidden.
+- **Anthropic quota probe.** Opt-in via `~/.olp/config.json providers.anthropic.quota_probe_enabled: true`. Parses the canonical `anthropic-ratelimit-unified-*` response-header schema (13 fields) from a minimal `POST /v1/messages` probe. Reuses the spawn-path OAuth credentials — env var → `~/.claude/.credentials.json` → macOS Keychain. Refresh-on-401, stale-cache-on-failure.
+- **`olp doctor anthropic.quota_probe_reachable`.** New check surfaces probe health. Returns `status: ok` with parsed utilization when fresh, `warn` on stale cache, `fail` with `human_steps[]` auth-aware recipe (re-login via `claude setup-token` or wait-and-retry).
+- **Provider matrix.** Anthropic ✅ live (13 fields). OpenAI ❌ no public quota API. Mistral ❌ no member-key-accessible quota endpoint (Admin API exists but org-admin-scoped, out of scope for trusted-LAN deployment per ADR 0011). All three pinned in `models-registry.json quota_probe.<provider>` block.
+
+### What's new for contributors
+
+- **ADR 0012 (Phase 5 charter)** — D-day plan + exit gate + scope boundaries (`docs/adr/0012-phase-5-charter-quota-probes-dashboard.md`).
+- **ADR 0002 Amendment 8** — first Class-specific Exception to the plugin contract: `quotaStatus()` may call provider HTTP APIs directly, subject to three constraints (READ-ONLY, subscription-scope, idempotent-failure) and the per-endpoint enumeration in ADR 0013 Rule 2.
+- **ADR 0013** — seven rules covering OAuth READ-ONLY consumption + dual-path schema-drift mitigation (compiled-binary `strings` + live API probe diff, since Claude Code v2.1.x is now a Mach-O / ELF binary with no `cli.js` to grep).
+- **`models-registry.json quota_probe.schema_version`** — pinned at `2026-05-26` (13 fields). Bump on schema-drift events per ADR 0013 Rule 5.
+- **Test seams** — 5 underscore-prefixed exports in `lib/providers/anthropic.mjs` (`_setQuotaUrlsForTest`, `_resetQuotaProbeStateForTest`, `_resetQuotaStateOnlyForTest`, `_getQuotaProbeStateForTest`, `_setQuotaAuthReadFnForTest`) for hermetic probe testing. Production code must not call them.
+- **ALIGNMENT.md § Class-specific Exceptions** — gains its first numbered exception (Anthropic plan-usage probe via direct `/v1/messages`).
+- **Audit memory at `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`** — schema canon + verification protocol + OCP institutional history.
+
+### D-day-level changes (Phase 5)
+
+- **D79** (PR #50 + cleanup PR #51): governance layer — ADR 0012 charter, ADR 0002 Amendment 8, ADR 0013, ALIGNMENT.md Class-specific Exceptions entry, D84 Mistral NO-GO disposition.
+- **D80** (PR #52): ported OCP `server.mjs:842-1109` to `lib/providers/anthropic.mjs:quotaStatus()`. Adds macOS-keychain reader to `readAuthArtifact()`. Parses all 13 fields including 3 new since OCP's 2026-04 capture (`5h-status`, `7d-status`, `overage-reset`). Implements 5min cache + 60s-3600s exponential refresh backoff + stale-cache-on-failure + opt-in config flag + `anthropic.quota_probe_reachable` doctor check. ~250 LOC.
+- **D81** (PR #53): added `lib/audit-query.mjs aggregateProviderQuota()` + `/v0/management/dashboard-data quota_v2` field + `/v0/management/quota quota_v2` field. Pinned `quota_probe.schema_version` in `models-registry.json`. Legacy `quota` field stays alongside for backwards compat until v1.0.0. ADR 0008 Amendment 1 documents the shape.
+- **D82** (PR #54): `dashboard.html` restructure — Claude.ai-style Plan Usage panel above the existing 4 panels. Per-provider rows with utilization bars, reset countdowns, status chips, representative-claim badges, overage chips, "Updated N min ago" labels. 60s `setInterval` with `visibilitychange` pause/resume. Manual refresh button with 2s spam guard. Graceful fallback to legacy `quota` when `quota_v2` absent. Closes v1.x roadmap #8.
+- **D83** (PR #55): Suite 38 (20 quota-probe unit tests covering all 13-header parse + cache + backoff + 401-refresh + 429-stale + schema_version + 5 doctor status paths) + Suite 39 (8 dashboard rendering smoke tests covering /dashboard 200/401 + key D82 HTML strings). Added 5 test seams to anthropic.mjs. 727 → 755 tests, 0 fail. Fold-in commit added 38j positive-path coverage (38j2: 401 → refresh succeeds → retry 200) per reviewer finding; total 756.
+- **Close-prep** (PR #56): README § Plan Usage section + § Supported Providers Quota-probe column + dashboard screenshot + `docs/exit-gates/phase-5-e2e.json` live verification artifact. Fold-in commit addressed 3 maintainer accuracy findings (doctor-kind framing / Mistral admin-API acknowledgment / SPOT drift closure via `quota_probe.openai` + `quota_probe.mistral` registry entries).
+
+### Out of Phase 5 scope (deferred to later)
+
+- **D84 Mistral probe.** NO-GO per 2026-05-26 spike: no member-key-accessible quota endpoint at `docs.mistral.ai/api`. Re-entry point pinned at `lib/providers/mistral.mjs DL-7`; re-evaluate if Mistral publishes a member-key surface or if OLP deployment posture expands to org-admin scope (Mistral Admin API exists).
+- **OpenAI / codex probe.** Permanently skipped — `openai/codex` CLI has no public quota API.
+- **`X-OLP-Cost-USD` per-request header.** Deferred to Phase 6 (depends on per-(provider, model) cost weights table).
+- **`context_window_exceeded` fallback trigger.** Deferred (trigger condition not yet observed).
+- **Automated schema-drift detector.** ADR 0013 Rule 5 codifies a procedural runbook (Annual Alignment Audit + `olp doctor` probe-failure + manual maintainer attention at major `claude --version` bumps), not an automated alarm.

+- **G11 fix (repo visibility).** Repo `dtzp555-max/olp` flipped from PRIVATE → PUBLIC during this session, closing the original G11 finding (`bash <(curl -fsSL .../main/bin/olp-connect)` returned 404 because anonymous curl can't fetch from private repos). README's `/main/` URL works going forward; GitHub's raw CDN may serve a stale 404 for `/main/` for ~5-15min after the visibility flip due to negative caching. D78 defends against this by adding a **tag-pinned URL (`/v0.4.4/bin/olp-connect`) as the primary recommendation in README**, with `/main/` listed as an alternative for trusted-head users. Tag-pinned URLs bypass the negative-cache because the tag ref was never queried while the repo was private.
+- **G12 fix (`detect_openclaw` claimed plugin not shipped).** `bin/olp-connect`'s OpenClaw detection block said `"The OpenClaw OLP plugin (D71-D73) is NOT YET SHIPPED"` — but D71-D73 shipped `olp-plugin/` at v0.4.0. D78 replaces the stale text with real install instructions: `git clone` + `openclaw plugins install ./olp-plugin/` (or symlink), edit `~/.openclaw/openclaw.json` with a dedicated bot apiKey, restart gateway. Points at `docs/integrations/openclaw.md` for the full setup.
+- **G13 fix (`olp-connect` self-version hardcoded literal).** Pre-D78 the script declared `OLP_CONNECT_VERSION="0.4.0-phase4"` as a hardcoded literal that nobody updated through v0.4.1 / v0.4.2 / v0.4.3 (the maintain-the-literal-per-release pattern is reliably forgotten). D78 derives the version at runtime from the sibling `package.json` via python3 — when the script is invoked from a checked-out repo, version resolves to the actual `package.json` value; when invoked via `curl … | bash` with no on-disk package.json next to it, falls back to `unknown`. Now `bash bin/olp-connect --version` prints `olp-connect 0.4.4` automatically with no manual touch needed at the next release.
+
+**Pre-publish audit.** Per `~/.cc-rules/docs/guides/pre-publish-audit.md` checklist (2026-05-26 session, before the visibility flip):
+- Identity scrub: 0 hits (no personal names / hostnames / home paths / personal emails leaked into the working tree)
+- Credential scrub: 0 real tokens — all `olp_` matches are placeholder (`olp_XXXX...`) or test fixtures (`olp_not-a-real-key-...`); gitleaks: "no leaks found"
+- Git-history author emails: 78 commits, two emails (`dtzp555@gmail.com` local + `taodeng1977@gmail.com` GitHub-account squash-merges). Maintainer chose Option A (accept) — the GitHub-account email was already verified-public on the maintainer's GitHub profile, so the visibility flip exposes nothing new.
+
+**Test count:** 717 (v0.4.3) → 720 (v0.4.4). +3 D78 regression tests in Suite 36:
+- 36v — pins absence of `NOT YET SHIPPED` text + presence of real install path
+- 36w — pins runtime version derivation from package.json (hardcoded literal gone)
+- 36x — pins README's tag-pinned-URL recommendation
+
+**Authority:** D77 MacBook client-install verification session (2026-05-26); `~/.cc-rules/docs/guides/pre-publish-audit.md`. Process learning: every README that includes a `curl <raw-URL> | bash` install pattern should pin to a release tag (not `/main/`) for CDN-cache resilience. The /main/ form is correct for the long-tail (when no negative cache exists) but the tag-pinned form survives the visibility-flip transient + survives any future force-push to main.
+
+**Out of D78 scope:**
+- F6 (doctor client-side vs server-side check separation) — Phase 5 ADR amendment.
+- D75 reviewer P2-1 (ADR 0004 per-hop schema amendment) + P2-2 (defensive `typeof hopModel === 'string'` invariant) — both genuine follow-ups, neither blocking.
+- `scripts/migrate-from-ocp.mjs` — Phase 7.
+
+## v0.4.3 — 2026-05-26
+
+### D76 — README install-path overhaul + `OLP_BIND` env + AI-driven install prompt + ADR 0011 amendment
+
+Patch release closing the install-experience gap. v0.4.0–v0.4.2 README's Quick Start was placeholder text with fictional commands (`npm install -g @dtzp555-max/olp` — package isn't published; `olp setup` / `olp start` — don't exist). 10 real gaps catalogued + fixed in one D-day; `OLP_BIND` env wired so the documented LAN onboarding flow actually works; AI-driven install prompt added per the Phase 4 charter brainstorm's #2 OCP inheritance candidate (was deferred at D64-D67 to the doctor framework only; D76 closes the README half).
+
+- **G1-G7 (README "Quick Start" was fictional)** — rewrote § "Manual install" with the real sequence: prerequisites (Node ≥ 18 + provider CLI install matrix) → `git clone` → `npm test` verify → `olp-keys keygen --owner` first → provider OAuth (claude/codex/mistral per-CLI flows) → write `~/.olp/config.json` with the minimum that actually serves traffic → `npm start` → smoke-test → IDE pointing. Each step empirically verified against the PI231 + Mac mini E2E session (2026-05-26).
+- **G8 (LAN unreachable — F5)** — added `OLP_BIND` env (default `127.0.0.1`). Operators set `OLP_BIND=0.0.0.0` (or a specific LAN IP) to accept LAN connections so `olp-connect <ip>` can actually reach the server. Pre-D76 the server was hard-coded to `server.listen(PORT, '127.0.0.1', ...)`, making the documented LAN-onboarding flow only usable through an SSH tunnel. ADR 0011's original wording referenced a `BIND_ADDRESS` concept that didn't exist; D76 makes it operational.
+- **G10 (no AI-install pattern)** — README § "Install with your AI (the fast path)" added. Verbatim prompt that the operator pastes into Claude Code / Cursor / Copilot / Aider; the AI follows the README + uses `olp doctor --json` machine-readable `next_action.ai_executable[]` (D64-D67) for self-repair, stopping only when `human_required[]` is non-empty (the provider OAuth dances). This closes the Phase 4 brainstorm Top-5 inheritance candidate #2 — the OCP "paste this prompt" pattern that D64-D67 only half-built.
+- **Opening compressed** — § "Why OLP" (3 paragraphs of OCP billing history) removed from the top. The OCP-trigger context moved to § "Migration from OCP" at the bottom, condensed into a single paragraph. New users land on value-prop + § "What you get" + § "Install with your AI" / § "Manual install" without needing to digest 2026-05-14 / 2026-06-15 Anthropic billing history first. OCP users get a one-line pointer at the top.
+- **§ "Configuration" full schema documentation** — replaced the placeholder with the actual `~/.olp/config.json` schema including every field that v0.4.x reads. Cross-references ADR 0004/0007/0010/0011.
+- **§ "Environment Variables" extended** — added `OLP_BIND`, `OLP_API_KEY`, `OLP_OWNER_TOKEN`, `OLP_PROXY_URL` rows that were used throughout the manual-install flow but undocumented.
+
+**ADR 0011 § "Deployment configurations" amendment.** Codifies the three deployment trust contexts (`127.0.0.1` loopback / RFC1918 + tailnet LAN / `0.0.0.0` public — with `advertise_anonymous_key: true` only safe in the first two). Documents the new `anonymous_key_advertised_with_lan_bind` startup warn event. Closes ADR 0011's pre-D76 dangling reference to a non-existent `BIND_ADDRESS`.
+
+**Test count:** 714 (v0.4.2) → 717 (v0.4.3). +3 D76 regression tests in Suite 36 (36s/36t/36u) pinning `OLP_BIND` wiring + safety warn + ADR amendment.
+
+**Out of D76 scope (deferred):**
+- F6 (doctor client-side vs server-side check separation) — needs design ADR for a `--remote` mode. Phase 5.
+- D75 reviewer P2-1 (ADR 0004 amendment for per-hop schema) + P2-2 (defensive `typeof hopModel === 'string'`) — both genuine follow-ups, neither blocking.
+- `scripts/migrate-from-ocp.mjs` — Phase 7.
+
+**Authority:** PI231 + Mac mini E2E session (2026-05-26, post-v0.4.2 verification revealed the 10 README gaps); ADR 0011 amendment self-cites; Phase 4 charter (ADR 0010) Top-5 inheritance candidate #2 (AI-driven self-repair). Process learning: every D-day reviewer rubric should add "open README in §-Quick-Start and verify the commands literally exist + work in the current repo" — would have caught G1-G7 at v0.4.0.
+
+## v0.4.2 — 2026-05-26
+
+### Post-v0.4.1 hotfix batch (D75) — real-machine E2E findings
+
+Patch release fixing 5 bugs caught by **real-machine E2E testing on PI231 + Mac mini (2026-05-26 session)** — bugs that prior D-day reviewers AND the post-v0.4.0 maintainer review both missed because they reviewed against spec text and against the local OLP install's `~/.codex/auth.json` shape (cached from an older codex CLI version), not against real provider CLIs running on a remote operator host that did `npm install -g @openai/codex` for the first time on 2026-05-26 and got codex CLI v0.133.0.
+
+**Root cause of the missed-bug class.** D6 (codex plugin authoring) explicitly documented three unpinned assumptions (A3 = access-token field name, A4 = NDJSON event schema, A2-adjacent = trusted-directory sandbox). D6 noted "D7 E2E will pin." D7 then shipped without performing real-codex-CLI E2E (the E2E gating mark was carried but the actual run was deferred). Every subsequent D-day reviewer trusted the D6/D7 codex plugin code unchanged because the static review couldn't see that the v0.133.0 CLI had moved the auth-token field, the event schema, AND added a new trusted-directory sandbox flag. The D74 maintainer review focused on `/health` / `/cache/stats` / `/v0/management/dashboard-data` payload shapes — none of which exercise the codex plugin's spawn path. F7 (per-hop model override) is a different class of miss — every reviewer read `executeHopFn(provider, model, ir)` and saw `model` consumed for cache key + audit ctx, but none traced through to confirm `model` is ALSO substituted into the IR passed to `provider.spawn()`. The function signature implied per-hop semantics that the body never fully delivered.
+
+- **[F1] codex auth.json schema pin — codex CLI v0.133.0 nests the access token under `tokens.access_token`** (verified empirically on PI231 / Mac mini, 2026-05-26). Pre-D75 `readAuthArtifact()` read only top-level `creds.access_token` / `creds.token` / `creds.accessToken` — all undefined under v0.133.0 → returned `null` → OLP reported "auth artifact missing" via `/health` and `olp doctor` AND refused to spawn codex even when the user had fully completed `codex login`. Fix: prepend `creds?.tokens?.access_token` to the precedence chain at BOTH call sites (`OPENAI_CODEX_AUTH_PATH` override branch + default `$CODEX_HOME/auth.json` branch). Legacy top-level fields preserved as fallback for backward compat with older codex CLI versions.
+- **[F2] codex spawn args — codex CLI v0.133.0 trusted-directory sandbox requires `--skip-git-repo-check`.** v0.133.0 refuses with `"Not inside a trusted directory and --skip-git-repo-check was not specified."` when spawned outside a git repo, exits non-zero with zero NDJSON output → OLP surfaces `SPAWN_FAILED` with no usable chunks → the fallback engine advances to next hop unnecessarily even when codex is configured and authenticated. OLP's typical deploy CWD (`~/olp/`) is NOT a git repo on operator hosts. Fix: add `'--skip-git-repo-check'` to the args array before `--model`. OLP is the trusted caller (operator's own server invoking the operator's own subscription via documented `codex exec` automation); the sandbox safeguards interactive shells, not pre-authorized automation.
+- **[F3] codex NDJSON event shape pin — codex CLI v0.133.0 emits `item.completed` + `turn.completed` + `turn.failed`**, not the D6-assumed `content`/`delta`/`text` + `type:'stop'`/`done:true` shapes. Real v0.133.0 stream (verified empirically): `{"type":"thread.started",...}` → `{"type":"turn.started"}` → `{"type":"item.completed","item":{"id":"item_0","type":"agent_message","text":"<response>"}}` → `{"type":"turn.completed","usage":{...}}`. Pre-D75, every chunk was silently dropped by `codexChunkToIR()` → response body had `content: null`. Fix: prepend three new recognizers (`item.completed` with `item.type === 'agent_message'` → IR delta; `turn.completed` → IR stop; `turn.failed` → IR error). Legacy D6 defensive recognizers preserved below as forward/backward compat fallbacks.
+- **[F4] `olp status` reads `body.stats.cache.size` (not OCP-era `body.cache.entries`).** Same class as D74 P2-3 (which fixed `cmdUsage` + `cmdCache`); D74 missed the parallel bug in `cmdStatus`. Server payload nests cache stats as `body.stats.cache.{hits, misses, size, inflightCount}` per `server.mjs handleManagementStatus`, and `CacheStore.stats()` has no `entries` field per `lib/cache/store.mjs`. Pre-D75 output showed `entries=?`. Fix: read `c.size` for entries display; also surface `inflightCount` when present.
+- **[F7] per-hop chain `model` field now overrides IR model in `provider.spawn()`.** Pre-D75 `executeHopFn(hopProvider, hopModel, irReq)` used `hopModel` for cache key + audit ctx but passed the ORIGINAL `irReq` (with `irReq.model` = user's original request) to `hopProviderPlugin.spawn(irReq, authContext)`. A chain config `[{provider:anthropic, model:claude-X}, {provider:openai, model:gpt-5.5}]` would always spawn BOTH plugins with `--model claude-X` — openai rejected the unknown model and the chain died. This broke the core OLP value prop (cross-provider fallback with provider-appropriate model substitution per hop). Fix: build a per-hop IR variant with `{...irReq, model: hopModel}` and pass that to spawn. Conditional skips clone when `hopModel === irReq.model` (common case: single-provider chains, or single-hop chains where the chain config repeats the request model). Applied to BOTH the buffered path (`executeHopFn`) AND the streaming path (`sourceFactory` for `getOrComputeStreaming`). **Authority:** ADR 0004 § Chain advancement step 1 (per-hop config supplies provider AND model — the contract was always specified, but the code didn't complete it).
+
+**Phase 5 process learning recorded.** Every provider plugin's D-day must include a real-CLI E2E ON A REMOTE OPERATOR HOST before merging — not on the maintainer workstation (which may have an older CLI cached from a prior install, hiding new field renames / new sandbox flags / new event shapes). The D6/D7 codex E2E was deferred and that deferral compounded across 3 layers (D6 = unpinned, D7 = pinning deferred, D8+ = trusted D6/D7 unchanged). F7 reinforces a separate lesson: when a function signature takes `(provider, model, ir)`, reviewers must check that `model` is consumed everywhere downstream, not just at the call site they happened to look at.
+
+**Out of D75 scope (deferred to Phase 5 explicit ADR amendments):**
+- F5 (server bind 127.0.0.1 / `OLP_BIND` env) — needs `lib/keys.mjs` anonymous-key trust boundary review before binding to non-loopback by default
+- F6 (`olp doctor` client-vs-server-side limit detection) — needs design ADR amendment for trigger taxonomy
+
+- **Test count delta:** 704 (v0.4.1) → 714 (v0.4.2). +10 D75 regression tests in Suite 36 (36i through 36r).
+- **Files touched:** `lib/providers/codex.mjs` (F1+F2+F3), `bin/olp.mjs` (F4 cmdStatus), `server.mjs` (F7 buffered + streaming spawn sites), `test-features.mjs` (Suite 36 extension), `package.json` (version), `CHANGELOG.md` (this entry).
+- **Authority:** ADR 0002 (provider contract — codex plugin), ADR 0004 (fallback engine — per-hop model contract), `lib/providers/codex.mjs` D6 assumption A2/A3/A4 docstrings (which all said "D7 will pin" and D7 never did); codex CLI v0.133.0 on-disk schema + `codex exec --help` output verified empirically on PI231 (2026-05-26 E2E session); Iron Rule 第二律 evidence-over-should-work; CLAUDE.md `release_kit.phase_rolling_mode` cross-Phase discipline.
+
+## v0.4.1 — 2026-05-26
+
+### Post-Phase-4 hotfix batch (D74) — maintainer-review findings
+
+Patch release fixing 5 issues caught by maintainer post-v0.4.0 independent review. Every finding was a real runtime bug that the per-D-day fresh-context opus reviewers all missed because they reviewed against spec text, not against the runtime contract (default `auth.allow_anonymous: false`, real `/health` payload shape, real `/cache/stats` payload shape, real `/v0/management/dashboard-data` payload shape). **Phase 4 lesson: future implementation D-days MUST include at least one test that boots the server with the default production config and exercises the new feature end-to-end** — not just stub-mocked codepaths.
+
+- **[P1-1] `olp doctor` no longer false-negatives on auth-required `/health`.** `lib/doctor.mjs` now accepts an `authHeaders` option (threaded from `bin/olp.mjs` `cmdDoctor` via the existing `authHeaders()` chain) and passes it to the `server.running` + `server.version` probes. The `server.running` check now distinguishes 401/403 ("server up but bearer token missing/invalid — set `OLP_API_KEY`") from "server unreachable" — so the `kind` discriminator routes to a clean fix-auth path instead of `fix_server` when the operator just forgot to export the env var.
+- **[P1-2] `bin/olp-connect` validates token shape + shell-quotes rc writes.** New `validate_olp_token <key> <source>` helper enforces the `^olp_[A-Za-z0-9_-]{43}$` regex (per ADR 0007 § 3 token format) at all 3 input sites: `--key` arg, `/health.anonymousKey` server-advertised consumption, and the interactive prompt fallback. New `shell_quote <value>` helper wraps rc-file writes (`export OPENAI_BASE_URL=$(shell_quote ...)`) so even a hypothetical bypass of the validator can't inject shell metacharacters into a sourced rc. systemd `environment.d/olp.conf` write additionally rejects embedded newlines. Hostile or malformed keys can no longer persist as shell startup injection.
+- **[P2-3] `olp usage` + `olp cache` human formatter rewritten against the real payload shape.** `cmdUsage` previously read `body.usage_24h.requests` / `body.providers` / `body.top_fallback_chains` — all undefined under the actual server payload shape — so users saw "requests: ?" + missing per-provider quota + missing top-chains. Now reads `body.window_24h.request_count` / `body.cache_hit_24h.hit_rate` / `body.quota` / `body.top_fallback_chains_24h` per `server.mjs:2027` + `lib/audit-query.mjs`. `cmdCache` previously read `body.entries` / `body.bytes` / `body.maxBytes` (OCP-era field names). Now reads `body.size` / `body.inflightCount` per `CacheStore.stats()` and computes hit rate from `hits + misses`.
+- **[P2-4] `olp-plugin/` `fmtHealth` iterates `providers.status` correctly.** Previously walked `Object.entries(body.providers)` which surfaced `enabled` / `available` / `status` as pseudo-providers (chat output showed `🟢 status` instead of `🟢 anthropic`). Now extracts the real provider map from `body.providers.status` and renders enabled/available counts in a header line + per-provider names with `activeSpawns` when present. Falls back to flat `body.providers.*` for the older OCP shape (backwards compat).
+- **[P3-5] Stale v0.3.0-era doc strings updated.** README header status line + Implementation Status § now reflect v0.4.0 shipped + Phase 5 open. `server.mjs` startup banner no longer hardcodes "Phase 1 in progress" (now just lists version + provider count — derives accurate state from `VERSION` without future maintenance touch-ups).
+
+**Phase 4 process learning recorded.** Per Iron Rule 第二律 (evidence over "should work"), every D-day review pass must include at least one runtime smoke against the default production config. The D-day reviewer rubric is updated implicitly — D74 Suite 36 tests pin the wire-contract shape so a future D-day refactoring server payloads can't silently re-break the CLI / plugin / docs.
+
+- **Test count delta:** 696 (v0.4.0) → 704 (v0.4.1). +8 D74 regression tests in Suite 36.
+- **Files touched:** `lib/doctor.mjs` (P1-1), `bin/olp.mjs` (P1-1 + P2-3), `bin/olp-connect` (P1-2), `olp-plugin/index.js` (P2-4), `server.mjs` (P3-5 banner), `README.md` (P3-5), `test-features.mjs` (Suite 36 regression), `package.json` (version), `CHANGELOG.md` (this entry).

+
+## v0.4.0 — 2026-05-26
+
+### Phase 4 — Operator + Client UX (D60 → D73)
+
+**Overview.** v0.4.0 closes Phase 4 — the "operator + client UX" track that grew OLP from "I built a multi-provider proxy" to "my family can use it without me holding their hand." 5 D-day groups (D60 → D73), ~13 D-days, all under standing-autopilot grant + per-D-day fresh-context opus reviewer per Iron Rule 10. The maintainer-triggered close PR lands all of it under one version tag.
+
+**Test count: 623 (v0.3.2) → 696 (v0.4.0).** +73 tests across the Phase 4 arc.
+
+**Strategic decision recorded:** Phase 4 explicitly DEFERS `/v1/messages` (Anthropic-shape entry surface) per ADR 0010 — re-open strictly gated on ADR 0009 P0 success AND maintainer-named family CC user. README posture: Claude Code listed as Not supported as an OLP client; recommended alternative "Cline + OLP" (same fallback chain available, better cross-provider compatibility because OpenAI tool schema is the multi-provider lingua franca).
+
+**Phase 4 release_kit checklist**
+
+- [x] All 5 D-day groups landed on main (D60 + D61-D63 + D64-D67 + D68-D70 + D71-D73)
+- [x] CI green on every D-day merge commit + on this release commit's head
+- [x] Fresh-context opus reviewer on every implementation D-day group + per-D-day P0/P1/P2 fold-ins where applicable
+- [x] CHANGELOG "Unreleased" promoted to "## v0.4.0 — 2026-05-26"
+- [x] `package.json` bumped 0.3.2 → 0.4.0
+- [x] `CLAUDE.md release_kit.phase_rolling_mode.current_phase` Phase 4 → Phase 5; `current_pre_release_identifier` `0.4.0-phase4` → `0.5.0-phase5`

+- [ ] `release.yml` triggered + GitHub Release created (auto on tag push)
+
+---
+
+### D60 (PR #40) — Phase 4 charter (ADR 0010) + default port 3456 → 4567
+
+Opens Phase 4. No functional code change beyond the default port value; substantive D-day work lands D61 onward.
+
+- **Default `OLP_PORT` changed `3456 → 4567`.** OCP defaults to 3456; OLP and OCP can now co-host on the same machine without `OLP_PORT` env override. Tests use `port: 0` ephemeral — no test-surface impact.
+- **ADR 0010 (Phase 4 charter) ratified.** Records 5 D-day group scope + explicit DEFER of `/v1/messages` with re-open trigger.
+- **ADR 0001 + ADR 0008 amendments.** Port-conflict assumption struck-and-amended; § 6.6 default-port reference updated.
+- **README quick start + Environment Variables table + Migration from OCP § note** updated.
+
+### D61-D63 (PR #41) — SSE heartbeat + recentErrors[20] + /v0/management/status
+
+First substantive Phase 4 implementation. 3 D-days bundled per Iron Rule 11 IDR (shared observability surface).
+
+- **SSE heartbeat** via `streaming.heartbeat_interval_ms` config (default `0` = disabled, matches OCP safe default). When enabled, streaming branch emits `: keepalive\n\n` SSE comment every interval during silent windows; resets on real chunk; cleans up on stream end/error/abort/disconnect. Eager-headers-post-spawn from day one (the OCP `db11105` lesson). `X-Accel-Buffering: no` centralized via new `SSE_DEFAULT_HEADERS` constant. Per-attached-client lifecycle (each tee output gets its own timer).
+- **`recentErrors[20]` ring buffer.** Module-scope bounded ring, populated from 5 server-side error paths. Filter: only `ProviderError` OR `statusCode >= 500` (401/403 brute-force noise excluded; D61-D63 reviewer P2-1 explicit-401/403-reject fold-in). Path sanitization via OCP `server.mjs:1395` port. In-memory only (per OCP precedent).
+- **`GET /v0/management/status` combined endpoint** (owner-only_block). Returns `{ ok, version, uptime_ms, uptime_human, started_at, providers, stats, recent_errors, generated_at }`. `_totalRequests` + `_activeRequests` module-scope counters with idempotent-decrement guard.
+- **Authority:** ADR 0010 § D61-D63; OCP `server.mjs:660-685` (startHeartbeat), `301, 354-358` (ring), `1151-1188` (/status), `1395` (path sanitization), commit `db11105` (eager-headers); ADR 0007 § 7 + ADR 0008 (owner-only_block pattern).
+- **Test count delta:** 623 → 636 (+13).
+
+### D64-D67 (PR #42) — `olp` Node CLI + `olp doctor` framework + per-provider doctor checks + ADR 0002 Amendment 7
+
+Second substantive Phase 4 implementation. 4 D-days bundled — CLI dispatches to doctor; doctor calls plugins via new contract method; ADR amendment authorizes the contract change.
+
+- **`bin/olp.mjs` Node CLI** with 11 subcommands: `status / health / usage / models / cache / providers / chain show / logs / restart / keys / doctor / help`. Node not bash (per ADR 0010 § Notes — bash's python3 JSON-parsing fragility avoided). Token resolution: `OLP_API_KEY` env → `OLP_OWNER_TOKEN` env → helpful 401 message (filesystem manifest tokens are one-way SHA-256 per ADR 0007 § 5, not recoverable). Output: human-readable ANSI text by default, `--json` for scripting. Exit codes `0=ok / 1=usage / 2=network|HTTP / 3=auth`. Installed via `package.json bin.olp` so `npx olp <subcommand>` works.
+- **`lib/doctor.mjs` framework** with machine-readable `next_action.ai_executable[]` for AI-driven self-repair. Per check: `{ id, category, async run(): { status: 'ok'|'fail'|'warn', message, evidence? } }`. Built-in checks: `server.running / server.version / config.exists / config.providers_enabled / config.chains_configured / auth.owner_key_exists / system.node_version`. Per-provider checks dynamically collected via the new `provider.doctorChecks()` contract method. `--json` output emits `{ checks, kind: noop|update|fix_oauth|fix_config|fresh_install|fix_server|fix_provider, next_action: { ai_executable, human_required, verify }, summary }`. `--check <id|category>` for tight repair-loop fast paths. Reviewer P2 fold-in: `_shellQuote()` helper hardens `ai_executable[]` against malicious `OLP_HOME` shell-metacharacter injection.
+- **Per-provider `doctorChecks()`** in anthropic / codex / mistral plugins: CLI-availability probe + auth-presence probe. Each fail returns `evidence.fix_commands` (for `ai_executable[]`) or `evidence.human_required`.
+- **ADR 0002 Amendment 7** adds OPTIONAL `provider.doctorChecks(): DoctorCheck[]` to the Provider contract — backwards compatible (plugins without it contribute no provider checks).
+- **`olp restart`** documented caveat (reviewer P2-2): `launchctl kickstart -k` does NOT re-read plist `EnvironmentVariables`; bootout/bootstrap dance noted for env reloads.

+### D68-D70 (PR #43) — `bin/olp-connect` + `/health.anonymousKey` + ADR 0011
+
+Third substantive Phase 4 implementation. 3 D-days bundled — olp-connect consumes /health.anonymousKey; both governed by ADR 0011 trusted-LAN invariant.
+
+- **`bin/olp-connect <host-ip>` (bash, 564 lines)** zero-config LAN client setup. Bash over Node so client machines without recent Node still work. Auto-detects 6 IDEs and configures each: Claude Code (detect + warn — NOT supported per ADR 0010), Cline (print VSCode-settings snippet — manual), Continue.dev (write idempotent `models:` entry to `~/.continue/config.yaml`), Cursor (snippet + WARNING about known base-URL fragility), Aider (write `OPENAI_API_BASE` + `OPENAI_API_KEY` to rc files), OpenClaw (detect + point at `olp-plugin/`). macOS `launchctl setenv` / Linux `~/.config/environment.d/olp.conf` for GUI-app env inheritance. `--dry-run` exercises every state-change site without modifying anything. Idempotent rc-file writes via bracketed `# OLP LAN ... # /OLP LAN` block.
+- **`/health.anonymousKey` opt-in field** + `auth.advertise_anonymous_key` config. Field appears in both trimmed AND full `/health` payloads when ALL THREE prerequisites hold: `auth.advertise_anonymous_key: true` + `auth.allow_anonymous: true` + at least one non-revoked guest-tier key has `plaintext_advertise` set. Default off — field ABSENT (not null), preserves v0.3.x `/health` shape. Three-prereq gate is graceful-degrade (server warns + boots; request-time re-checks).
+- **`bin/olp-keys keygen --anonymous --advertise`** new flag. Writes plaintext into manifest `plaintext_advertise` field AND prints WARNING + ADR 0011 pointer. Owner-tier rejected at BOTH CLI and lib layers (defense-in-depth). Reviewer P2-1 fold-in: `listKeys()` strips `plaintext_advertise` alongside `token_hash` — callers wanting the advertised plaintext for the `/health` publication path MUST go through `findAdvertisedKey()` (the only sanctioned read site).
+- **ADR 0011 (anonymous-key deployment-context)** new ADR codifying the trusted-LAN-only invariant. Threat model explicit; deployment-context table concrete; soft enforcement via startup warn if `BIND_ADDRESS` resolves to public IP AND `advertise_anonymous_key: true`. No hard allowlist (TLS-fronted private networks indistinguishable from public from server's perspective). Re-evaluation triggers named (Cloudflare Tunnel guidance / Phase 5 multi-tenant).
+- **Authority:** ADR 0010 § D68-D70; ADR 0011 (new); ADR 0007 § 4 (manifest forward-compat unknown fields) + § 7 (identity classes) + § 9 (keygen flow); OCP `ocp-connect` (port reference); 2026-05-26 brainstorm Top 5 inheritance candidate #3.

+
+Final Phase 4 substantive D-day group. 3 D-days bundled — plugin consumes existing endpoints; integration docs reference plugin + olp CLI + olp-connect together.
+
+- **`olp-plugin/` OpenClaw gateway plugin** (482 lines). Port of OCP `ocp-plugin/index.js` minus mutations. Subcommand parity with `olp` CLI: `/olp status / usage / cache` (owner-only) + `/olp health / models / providers / chain show / doctor / help` (informational). **Explicitly NOT ported** for security: `/olp keys keygen` (chat = brute-force-prone), `/olp keys revoke` (mutation), `/olp restart` (misclick risk), `/olp logs` (PII risk). Port resolution: `OLP_PROXY_URL` env → `OLP_PORT` env → plugin config `proxyUrl` → `http://127.0.0.1:4567` (D60 default). Output: Telegram/Discord monospace code block with status icons (🟢🟡🔴). Long responses truncated for 4096-char Telegram limit. No npm deps (OpenClaw provides Telegram/Discord transport).
+- **`docs/integrations/*.md` bundle** (6 pages + index). Per-IDE setup docs with status icons: Continue.dev ✅, Cline ✅ (cites Cline issue #7128 base-URL UI bug), Cursor ⚠️ (documented base-URL fragility), Aider ✅, **Claude Code ❌** (Anthropic wire format only; recommended alternative "Cline + OLP" per ADR 0010 § /v1/messages defer), OpenClaw ✅. Each ~60-120 lines: status / quick setup / known issues / OLP-specific notes / test-it command. `docs/integrations/README.md` is the index.
+- **README updates.** New § "IDE Setup" linking `docs/integrations/README.md`. New § "Telegram / Discord Usage" with install + configure + restart + use. Quick Start mentions `olp-connect <ip>` as family-onboarding command. `package.json files` field extended to include `olp-plugin/` so the published tarball ships it.

+## v0.3.2 — 2026-05-25
+
+### Post-Phase-3 cleanup batch #2 — streaming-path singleflight + TOCTOU close (D57 + D58 + D59)
+
+Patch release closing v1.x roadmap #1 end-to-end. The cache layer's D4 singleflight (one spawn per identical concurrent request) was fully wired on the buffered path since v0.1 but NOT on the streaming path — N concurrent identical streaming requests each spawned their own CLI process. v0.3.2 ships the streaming sibling: tee fan-out, late-joiner replay, per-client backpressure, AbortController propagation, and TOCTOU close. 3 D-day commits (D57 + D58 + D59); ADR 0005 Amendment 8 §§1–14 implemented.
+
+- **D57** (PR #36) — **cache layer.** New `cacheStore.getOrComputeStreaming(keyId, cacheKey, sourceFactory, opts) → { stream, isFirst, role }` mirroring `getOrCompute` on the streaming side. Internals: `_streamingInflight: Map<compositeKey, StreamingInflightEntry>` (composite key `keyId + '\0' + cacheKey`) with synchronous check+insert atomicity (closes TOCTOU per ADR 0005 Amendment 8 §1, §6); single-reader tee fan-out across all attached clients; late-joiner replay buffer (synchronous drain on attach; `STREAM_BACKPRESSURE` terminator if drain or replay-truncation would corrupt); per-client backpressure (`PER_CLIENT_QUEUE_CAP = 1 MB`, overridable via opts); accumulated replay cap (`ACCUMULATED_REPLAY_CAP = 10 MB`, mirrors D23 cache-entry cap); AbortController fires source-iterator return when all clients disconnect. New `'STREAM_BACKPRESSURE'` entry in `PROVIDER_ERROR_CODES` — NOT a hard trigger (whitelist-only `HARD_TRIGGER_CODES`). Suite 27 = 12 unit tests.
+- **D58** (PR #37) — **server wiring.** Streaming branch in `server.mjs` swapped from the peek+spawn pattern to `cacheStore.getOrComputeStreaming(...)`. `tryAcquireSpawn`/`releaseSpawn` moved INSIDE the `sourceFactory` closure per ADR 0005 Amendment 8 §7 (only the first caller acquires; attached joiners share the slot; release fires exactly once on source completion/error/abort). `CONCURRENCY_LIMIT` thrown by the factory triggers fallthrough to the buffered path (preserves today's behaviour). New `X-OLP-Streaming-Inflight: source | attached` HTTP header annotates per-response role (§11). New `cache_status: 'streaming_attached'` audit value tracks the singleflight win. `lib/audit-query.mjs` aggregate APIs (`aggregateRequests`, `cacheHitRateWindow`) extended with `cache_streaming_attached` / `streaming_attached` fields so the cache_status breakdown reconciles. `res.on('close')` propagates client disconnect into the tee's `attachedClients` accounting (§9). D16 truncated-not-cached invariant preserved via server-layer `cacheStore.delete` on stop-less exhaustion (the cache layer is IR-agnostic and writes accumulatedChunks on any source exhaustion; the IR-aware server deletes the entry when the source returned without a `{type:'stop'}` chunk). Suite 28 = 8 HTTP integration tests.
+- **D59** (PR #38) — **docs polish.** README § Known limitations bullet inverted to ✅ shipped marker. `docs/v1x-roadmap.md` #1 rewritten to closed state with 3-D-day breakdown. #6 (streaming SPAWN_FAILED salvage) unbundled from #1 because the tee architecture as implemented does not carry salvage semantics. Issue #16 closed with refs to PRs #36 / #37 / #38.
+- **Test count:** 603 (v0.3.1) → 623 (v0.3.2). +20 streaming-SF tests (Suite 27 = 12 unit, Suite 28 = 8 HTTP integration).
+- **Deferred sub-items (not blocking #1 closure):** (a) `X-OLP-Streaming-Inflight: solo` wire value not emitted — observable only post-stream via `streaming_inflight_source_done` log event's `attached_count: 0`. Future ADR amendment may expose via HTTP trailer. (b) `streaming_inflight_join` log event not emitted from the cache-layer `_attachClient` path because provider/model context lives in the sourceFactory closure (server-layer concern). (c) `isFirst` field returned by `getOrComputeStreaming` is unused by server.mjs (`role` supersedes); could be removed in a future cache-layer API cleanup.
+- **Authority:** ADR 0005 Amendment 8 (design ratified at D42 2026-05-25; implementation gated on maintainer "go" — fired 2026-05-25 post-v0.3.1). `docs/v1x-roadmap.md` #1 (closed). GitHub issue #16 (closed). ADR 0002 Amendment 6 (D38 `tryAcquireSpawn`/`releaseSpawn` semantics, now invoked from sourceFactory closure).
+
+**Patch-release classification.** Per `release_kit.phase_rolling_mode` cross-Phase discipline + maintainer release-cut decision (this session, 2026-05-25): the new wire surface (`X-OLP-Streaming-Inflight` header + `streaming_attached` cache_status) is semver-wise a minor bump, but this is roadmap-cleanup work — NOT Phase 4 product scope. The reserved `0.4.0` identifier stays for the formal Phase 4 close. v0.3.2 ships as a patch under the Phase 4 pre-release banner. Tag push triggers `release.yml`.
+
+## v0.3.1 — 2026-05-25
+
+### Post-Phase-3 cleanup batch #1 (D56)
+
+Patch release closing two XS v1.x-roadmap deferrals (`docs/v1x-roadmap.md` #4 + #7) that became actionable now that Phase 3 management endpoints exist. No new feature surface; pins existing behaviour into tests + finally wires the ADR-documented `activeSpawns` field on `/health`.
+
+- **AUTH_MISSING tuple test** (v1.x roadmap #7 / D45 reviewer P3 deferral). New engine-level test in Suite D40 asserts that an `AUTH_MISSING` hop produces a `fallbackDetail` tuple with `trigger_type: 'auth_missing'` AND that the engine does NOT advance past the AUTH_MISSING hop (per ADR 0004 § Decision — `HARD_TRIGGER_CODES[AUTH_MISSING] = false`). Pre-D56 the behaviour was implicit through other engine-path tests; this commit makes it explicit so a future refactor that moves the tuple-push past the auth_missing branch fails this test directly.
+- **`/health` `activeSpawns` integration** (v1.x roadmap #4 / ADR 0002 Amendment 6 forward note). `handleHealth` now surfaces `providers.status.<name>.activeSpawns` (sourced from D38 `getActiveSpawnCount(name)`). The field is computed BEFORE `healthCheck()` is awaited so it remains present even when `healthCheck()` throws (cheap in-memory counter read). New Suite 21c-extra test pins the field presence + non-negative value for every enabled provider. With no requests in flight: 0; under saturation: equals `hints.maxConcurrent`.
+- **Test count:** 601 (v0.3.0) → 603 (v0.3.1). +2 D56 tests.
+- **Authority:** `docs/v1x-roadmap.md` #4 + #7; ADR 0002 Amendment 6 (concurrency observability forward note); ADR 0004 § Decision + Amendment 5 (X-OLP-Fallback-Detail tuple shape).
+
+**Patch-release classification.** Per `release_kit.phase_rolling_mode` cross-Phase discipline: D56 landed on main after v0.3.0 was tagged, so this is a hotfix-class patch — bump patch, tag, release before next push. Tag push triggers `release.yml`.
+
+## v0.3.0 — 2026-05-25
+
+### Phase 3 — Dashboard + audit query layer + daily audit rotation (D48 → D54)
+
+**Overview.** v0.3.0 closes Phase 3 — the dashboard / audit aggregate query / daily rotation track that grew OLP from "audit ndjson exists but is grep-only" (v0.2.0) to a live multi-panel owner-only dashboard with aggregate queries + automatic daily file rotation. 7 D-day commits (D48 through D54) shipped between 2026-05-25 under the standing-autopilot grant. All 15 ADR 0008 § 10 acceptance criteria are implemented + tested.

+
+**Bonus: also resolved at D53** — D45 fresh-context opus reviewer P2 deferral (`tried_providers` semantics on `key_no_provider_access` 403). ADR 0007 § 8 amended; server.mjs sets `tried_providers = []` on the 403 path so downstream audit queries stay accurate.
+
+**Known limitations carried beyond v0.3.0**
+
+Phase 3 functional scope is complete. The following remain as Phase 4+ deferrals (tracked in `docs/v1x-roadmap.md` + the new Phase 4 entry below):
+
+- **Per-key per-provider auth artifact mapping** — ADR 0007 § 12. Each OLP key independently authenticated to a different provider account.
+- **Audit query rotation / retention policies** — ADR 0008 § 11. Currently unbounded; operator manages disk. A Phase 4+ amendment adds `audit_max_days` config when an operational need emerges.
+- **SQLite hybrid migration** — ADR 0007 § 13. Trigger: query latency > 2s on typical owner session OR > 5 owners polling. Requires engines bump + CI matrix change as a separate prior PR.
+- **Provider-cost weights for spend trend** — ADR 0008 § 11. At v0.3.0 "spend" is proxied by request count; cost integration when commercial cost-tracking lands.
+- **Per-key dashboard views** — owner sees aggregate; per-key drill-down is a future amendment.
+- **Key-mgmt UI on dashboard** — owner can create / revoke / edit keys from web. Out of Phase 3 scope; needs separate security review per ADR 0008 § 11.
+- **Manual smoke for dashboard** — per ADR 0008 § 10 #12 the "no JS console errors in real browser" sub-claim is manual / playwright; Phase 3 acceptance shipped with server-observable checks (Suite 25); a Phase 4+ amendment may add playwright smoke if dashboard complexity grows.
+
+### D54 — README Phase 3 polish (docs-only, no code change)
+
+Seventh Phase 3 D-day. Documentation polish ahead of Phase 3 close (D55, maintainer-triggered). Brings README status header / Implementation Status / API Endpoints / Known limitations / Phase plan up to date with Phase 3 work shipped to main through D48-D53.
+
+- **Status header**: `v0.2.0 shipped` → `v0.2.0 shipped; v0.3.0 in progress` + lists D48-D54 highlights.
+- **Implementation status note**: Phase 3 description updated from "next milestone" to "shipped to main through D54; v0.3.0 release pending maintainer-triggered close (D55)".
+- **Implementation Status table** — 4 row updates:
+  - `lib/audit.mjs`: 🟡 D45-only → ✅ D45 append + D52 rotation; describes both responsibilities.
+  - `lib/audit-query.mjs`: NEW row (D49 shipped, 5-function aggregate query API).
+  - `dashboard.html`: 📋 Planned (Phase 6) → ✅ Phase 3 shipped (D50 stub + D51 full UI); describes the 4 panels.
+  - `bin/olp-audit-rotate.mjs`: NEW row (D52 shipped, external cron tool).
+- **API Endpoints table** — `/cache/stats`, `/v0/management/quota`, `/dashboard` (Phase 6 📋 Planned → Phase 3 ✅ Shipped); new `/v0/management/dashboard-data` row; `/health` row clarified to spell out owner-only-trim semantic. Removed the "placeholder — full table lands" stub since the table is now substantively complete.
+- **Known limitations** — Phase 2 paragraph kept (now reads as historical Phase 2 completion note); new Phase 3 paragraph summarizing D48-D54 shipped + D55 close pending.
+- **Phase plan** — Phase 3 description (was "next") → "🟡 In progress — D48 (ADR) + D49–D54 shipped to main 2026-05-25; v0.3.0 close awaits maintainer trigger." Added Phase 4+ entry covering the deferred items (per-key per-provider auth, SQLite hybrid, audit rotation/retention policies, provider-cost weights).
+- **Test count:** 601 → 601 (docs-only).
+- **Authority:** CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; ADR 0008 § 13 sprint shape (D54 = "E2E + AGENTS / README polish"); standing autopilot grant.
+
+### D53 — `tried_providers` schema semantic fix (D45 P2 deferral closed)
+
+Sixth Phase 3 D-day. Small focused fix for the D45 fresh-context opus reviewer P2 finding that was deferred: `auditCtx.tried_providers` on the `key_no_provider_access` 403 path was being stamped with the ORIGINAL chain (which was filtered out, never dispatched), distorting downstream audit queries like "which providers did key X actually call".
+
+- **`server.mjs` 403 path fix** (around L815): `auditCtx.tried_providers = []` (was `_originalChainProviders`). The configured-but-blocked chain still appears in the human-readable error message body — the audit just doesn't claim those providers were "tried" when the server's filter dispatched zero.
+- **ADR 0007 § 8 amendment**: new paragraph spelling out the `tried_providers` semantic — "the list of providers the server actually dispatched a spawn against. A provider that was configured in the chain but filtered out by `providers_enabled` gating is NOT included — the key didn't try the provider, the gate did. On the 403 path `tried_providers` is the empty array." Plus a forward note that audit log rotation moved to Phase 3 / ADR 0008 § 5.
+- **Suite 20h-extra-audit (+1 test — 600 → 601):** creates a guest key with `providers_enabled: ['mistral']`; fires a request for an Anthropic-routed model; asserts 403 `key_no_provider_access`; reads the audit row from `audit.ndjson`; asserts `tried_providers === []`. This pins the D53 semantic against regression — if a future change reverts to stamping the original chain, the test fails.
+- **Documentation:** CHANGELOG D53 entry; ADR 0007 § 8 amendment.
+- **Test count:** 600 → 601 (+1 D53 regression test).
+- **Authority:** ADR 0007 § 8 amendment (D53, 2026-05-25); D45 fresh-context opus reviewer P2 deferral note; CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; standing autopilot grant.
+
+### D52 — Daily audit rotation (`lib/audit.mjs` extension + `bin/olp-audit-rotate.mjs`)
+
+Fifth Phase 3 D-day. Adds daily UTC-aware rotation to `lib/audit.mjs` per ADR 0008 § 5 + ships an external cron tool. Rotation is **synchronous** at v0.3.0 (Lane 3 = B daily rotation; synchronous design eliminates the race that an async wrapper would create between date-change-detection and the append).
+
+- **`lib/audit.mjs` extended**:
+  - New `_maybeRotateAudit({ olpHome, logEvent })` (synchronous): probes the live `audit.ndjson`; if it holds events from a past UTC date, renames it to `audit-YYYY-MM-DD.ndjson`. Idempotent. If the target file already exists (cron beat the in-server check), logs warn + skips per ADR 0008 § 5.3 race safety.
+  - `appendAuditEvent` extended: cheap fast-path date check via module-cached `_lastSeenUtcDate`. On date change, calls `_maybeRotateAudit` synchronously BEFORE `appendFileSync` — so old-date events land in the rotated file and new-date events land in the fresh live file. No event straddles the boundary.
+  - Why synchronous instead of async: an async wrapper would let the sync `appendFileSync` race the not-yet-completed `renameSync`, landing today's event in the about-to-be-renamed file. Sync rotation is the only correct ordering at the append-fired-from-many-routes scale OLP runs.
+  - New exports: `_maybeRotateAudit` (sync), `getAuditRotateCount`, `getAuditRotateFailCount`, `__resetAuditRotateState`, `__setLastSeenUtcDateForTesting`.
+  - First-event-date discovery: when probing the live file's date, reads only the first ndjson line + parses its `ts`. Falls back to file mtime if events absent (corrupt/empty edge).
+- **`bin/olp-audit-rotate.mjs`** (~95 lines): external cron tool per ADR 0008 § 5.2. Calls `_maybeRotateAudit` once + reports outcome. Exit codes 0 (success or no-op), 1 (bad usage), 2 (rotation failed). Installed via `package.json bin` so `npx olp-audit-rotate [--olp-home=<path>]` works. Example cron line documented in the file header.
+- **Concurrent-safety semantics** (ADR 0008 § 5.3): in-process sequential appends after the first date-change detection short-circuit via the updated `_lastSeenUtcDate` cache → exactly 1 rename even under N sequential appends. Cross-process (cron + server) coexistence handled by the "target already exists → skip + warn" branch.
+- **Test surface (Suite 26, +12 tests — 588 → 600):**
+  - 26a-1..5: `_maybeRotateAudit` (no live file / today already / yesterday→rotate / idempotent re-call / cron-race target-exists warn)
+  - 26b-1: `appendAuditEvent` past UTC date change triggers sync rotation + append lands in fresh live file
+  - 26c-1: 10 sequential `appendAuditEvent` across date change → exactly 1 rotation + all 10 events in new live file
+  - 26d-1..4: `bin/olp-audit-rotate.mjs` CLI (--help / no-live-file / yesterday-file-rotates / unknown-flag exit 1)
+  - 26e-1: rotated files queryable via `lib/audit-query.mjs` `discoverAuditFiles` + `readAuditWindow` cross-file read
+- **`package.json`**: `bin.olp-audit-rotate` + `scripts.olp-audit-rotate` entries added.
+- **Documentation:** AGENTS.md `lib/audit.mjs` marker promoted to ✅ (D45 append + D52 rotation both shipped); new `bin/olp-audit-rotate.mjs` entry.
+- **Test count:** 588 → 600 (+12 D52 tests in Suite 26).
+- **Authority:** ADR 0008 § 5.1 (first-append-after-UTC-midnight trigger), § 5.2 (external cron alternative), § 5.3 (concurrent-rotation safety + cron-coexistence semantics), § 5.4 (renamed-file query path consumed by D49 lib/audit-query.mjs); CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; standing autopilot grant.
+
+### D51 — `dashboard.html` full multi-panel UI (Phase 3)
+
+Fourth Phase 3 D-day. Replaces the D50 `dashboard.html` placeholder with the full 4-panel UI per ADR 0008 § 6. Vanilla HTML + JS + fetch — no build step, no framework, no CDN (Lane 1 = A). 30s page poll with `document.visibilityState` pause/resume (Lane 4 = A).
+
+- **4 panels rendered from `/v0/management/dashboard-data`** (the single backing endpoint, per Lane 2 in-memory query model):
+  - **Panel 1 — Per-provider quota**: table of `{ Provider | Available | Status }`; surfaces `null` available as "n/a" + capturing per-provider `provider.quotaStatus()` errors as a red status pill (graceful degradation per ADR § 9).
+  - **Panel 2 — Last 24h: request count + cache hit + fallback rate**: per-provider row of `{ Requests | Cache hit % | Fallback rate % }`. Cache hit sourced from `cache_hit_24h.by_provider[p].hit_rate`; fallback rate computed from `window_24h.by_provider[p].fallback_count / count`.
+  - **Panel 3 — Request count last 30 days (SVG sparkline)**: vanilla SVG bar chart with `<title>` tooltips showing per-day per-provider breakdown. Y-axis: requests per day (scaled to max); X-axis: 30 daily buckets (UTC). Each bar `<title>` includes the date + total count + provider breakdown.
+  - **Panel 4 — Top fallback chains (last 24h)**: numbered table of `{ # | Chain | Count | First seen | Last seen }` with chain arrows rendered in monospace (`anthropic → openai`).
+- **30s poll + visibilitychange pause** (ADR 0008 § 6.5):
+  - `setInterval(refresh, 30000)` after the initial fetch.
+  - `document.addEventListener('visibilitychange', ...)` → `stopPolling()` on hidden / `refresh() + startPolling()` on visible.
+  - Per ADR § 6.5 this prevents 2880 background polls/day per owner when the dashboard tab is in the background.
+- **Error handling**:
+  - 401 from `/v0/management/dashboard-data` → in-page error banner explains owner-tier requirement + suggests SSH-tunnel + header-injection workaround (browsers can't natively send `Authorization: Bearer` without a proxy/extension).
+  - Other HTTP errors → generic "HTTP <code>" banner; console.warn for operator debugging.
+  - Per-panel "Loading…" / "No requests in window." / "No fallback chains triggered" empty states.
+- **DOM helpers**: small `el(tag, attrs, ...children)` + `svgEl(tag, attrs)` factories — no framework, ~10 lines each. Sparkline uses native `<title>` for tooltips (no JS hover handlers).
+- **Critical correctness invariants** (per ADR 0008 § 6 + Lane 1 = A):
+  - No `<script src>` — entire JS inline in `<script>` tag (Suite 25d asserts).
+  - No `<link rel="stylesheet" href=>` — all CSS in `<style>` tag (Suite 25d asserts).
+  - Only one backing endpoint hit: `/v0/management/dashboard-data` (Suite 25e asserts). All 4 panels consume slices of its response.
+  - 401 path keeps panels in last-good state rather than clearing them; operator sees the error banner + can debug.
+- **Test surface (Suite 25, +6 tests — 582 → 588):**
+  - 25a: owner /dashboard response contains all 4 panel container IDs (`panel-quota`, `panel-24h`, `panel-trend`, `panel-chains`).
+  - 25b: dashboard JS declares `POLL_INTERVAL_MS = 30000` + uses `setInterval` + `clearInterval`.
+  - 25c: visibilitychange listener wired + checks `document.visibilityState === 'hidden'`.
+  - 25d: NO external `<script src>` and NO external stylesheet `<link href>` — pinning Lane 1 = A.
+  - 25e: dashboard JS fetches `/v0/management/dashboard-data` (the single consolidated D50 endpoint).
+  - 25f: 401 in-page error banner mentions owner-tier so a maintainer who lands on a 401 knows the route forward.
+- **Manual smoke (ADR 0008 § 10 #12 manual acceptance)**: the dashboard renders without console errors in a real browser when served by a running OLP instance + owner-tier Bearer token injected via SSH-tunnel + header-injection extension. Not automated at Phase 3 (Lane 4 = A poll model doesn't need playwright; Phase 4+ may add a playwright smoke if dashboard complexity grows).
+- **Documentation:** AGENTS.md `dashboard.html` marker promoted from 🟡 D50 placeholder to ✅ D51 full UI.
+- **Test count:** 582 → 588 (+6 D51 tests in Suite 25).
+- **Authority:** ADR 0008 § 6 (panels + refresh + localhost) + § 6.5 (poll + visibilityState pause) + Lane 1 = A (no build step) + Lane 4 = A (30s poll) + Lane 5 = B (full 4-panel scope); ADR § 9 (graceful degradation surfaced in Panel 1); ADR § 10 criterion #12 (HTML smoke); CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; standing autopilot grant.
+
+### D50 — `server.mjs` management endpoints (Phase 3 dashboard wire-up)
+
+Third Phase 3 D-day. Wires the D49 `lib/audit-query.mjs` aggregate query layer into 4 owner_only_block HTTP endpoints per ADR 0008 §§ 7-8. Ships a placeholder `dashboard.html` at repo root (D51 lands the full multi-panel UI). All endpoints follow the Phase 2 / D45 auth + audit + touchLastUsed pattern.
+
+- **4 new endpoints** (all owner_only_block per ADR 0008 § 8 — anonymous + guest + missing-key all → 401):
+  - `GET /dashboard` — serves `dashboard.html` (Content-Type text/html; charset=utf-8). D50 stub explains the state + lists backing endpoints; D51 replaces with full UI.
+  - `GET /v0/management/dashboard-data` — full aggregate per ADR 0008 § 7.2: `{ generated_at, window_24h (auditAggregateRequests), cache_hit_24h (auditCacheHitRateWindow), quota (per-provider provider.quotaStatus + error capture), spend_trend_30d (auditSpendTrendDaily — exactly 30 entries), top_fallback_chains_24h (auditTopFallbackChains limit 10), cache_stats (live cacheStore.stats()) }`.
+  - `GET /v0/management/quota` — quota subset only (subset of dashboard-data; useful for scripted monitoring).
+  - `GET /cache/stats` — live in-memory `cacheStore.stats()` shape (`{ hits, misses, size, inflightCount }` + `generated_at` wrapper).
+- **`_runOwnerOnlyManagementEndpoint(req, res, method, path, inner)` helper** factors the common auth + audit ctx + owner-block + res.on('finish') wire. inner is async (req, res, olpIdentity, auditCtx) → returns void. Eliminates 4× boilerplate.
+- **`owner_only_block` mode** (ADR 0008 § 8): authenticate → if not owner → 401 `owner_required`. Distinct from `owner_only_trim` (Phase 2 /health pattern). Anonymous identity (when `allow_anonymous: true`) reaches the handler and is 401'd by the owner check — verified by Suite 24c.
+- **Provider quotaStatus error capture**: dashboard-data + quota endpoints catch per-provider throws and surface `{ provider, error, available: null }` so one bad provider doesn't fail the whole panel (ADR 0008 § 9 graceful degradation).
+- **`dashboard.html` placeholder** (~50 lines at repo root): explains the D50 state, lists backing endpoints with curl example. Cached in memory at first /dashboard request (`_loadDashboardHtml` with module-scope `_dashboardHtmlCache`); falls back to an in-memory stub if the file is missing (e.g., test imports from non-repo cwd).
+- **Audit on management endpoints** (ADR 0008 § 7.5): every management request appends an audit row including 401 paths (verified by Suite 24j). Touch wire skips anonymous + env-owner identities (matches Phase 2 pattern).
+- **Router**: 4 new GET branches added between /v1/chat/completions and the 404 fallback.
+- **Test surface (Suite 24, +11 tests — 571 → 582):**
+  - 24a-d: /dashboard owner_only_block (owner 200 / guest 401 / anonymous-with-allow_anonymous=true 401 / no-auth-with-allow_anonymous=false 401)
+  - 24e: dashboard-data owner → 200 JSON with all required ADR § 7.2 fields (asserts `spend_trend_30d.length === 30`)
+  - 24f: dashboard-data guest → 401 owner_required
+  - 24g: quota owner → 200 JSON with quota array
+  - 24h: cache/stats owner → 200 JSON with `{ hits, misses, size, inflightCount, generated_at }`
+  - 24h-401: cache/stats guest → 401
+  - 24i: successful dashboard-data appends audit row with `status_code: 200` + `key_id` + `path: '/v0/management/dashboard-data'`
+  - 24j: 401 (guest blocked) dashboard-data appends audit row with `error_code: 'owner_required'` + `owner_tier: 'guest'`
+- **Documentation:** AGENTS.md `lib/audit-query.mjs` D49 marker note added + new `dashboard.html` entry (D50 placeholder).
+- **Test count:** 571 → 582 (+11 D50 tests in Suite 24).
+- **Authority:** ADR 0008 § 7 (endpoints) + § 8 (owner_only_block mode) + § 9 (graceful degradation) + § 7.5 (audit on management endpoints); ADR 0007 § 7 (auth model reused); ADR 0002 § Provider contract (quotaStatus); ADR 0005 (cacheStore.stats); CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; standing autopilot grant.
+
+### D49 — `lib/audit-query.mjs` audit aggregate query layer (Phase 3)
+
+Second Phase 3 D-day. Implements ADR 0008 § 4 query API. Pure in-memory ndjson scan; cross-file walk over `audit.ndjson` (live) + `audit-YYYY-MM-DD.ndjson` (rotated). No server.mjs integration in this D-day (D50 wires the consuming endpoints).
+
+- **New file `lib/audit-query.mjs`** (~370 lines): 5 public API functions per ADR 0008 § 4.1:
+  - `discoverAuditFiles({ olpHome })` — filesystem scan; returns `Map<date|'live', path>`.
+  - `readAuditWindow({ startMs, endMs, olpHome, logEvent })` — generator over events in half-open window [startMs, endMs). Walks rotated date files + live file. Skips malformed lines + logs warn.
+  - `aggregateRequests({ windowMs, olpHome })` — counts + status buckets + by_provider + by_owner_tier + by_path + median/p95 latency over rolling window.
+  - `topFallbackChains({ windowMs, limit, olpHome })` — top-N chains by trigger count from events with `fallback_hops > 0`. Tied-count tiebreak: ascending first_seen.
+  - `spendTrendDaily({ days, olpHome })` — daily series ending today with sparse-fill for zero-request days. Per-day request_count + median latency + by_provider breakdown.
+  - `cacheHitRateWindow({ windowMs, olpHome })` — audit-derived cache hit rate (bypass excluded from denominator); per-provider + overall.
+- **PII discipline** (ADR 0008 § 4.3): every aggregate function relays only schema fields; never message content. Suite 23g actively asserts the absence of `content`/`message`/`messages`/`prompt`/`response`/`body` keys in every aggregate output.
+- **Cross-file walk semantics** (ADR 0008 § 4.2): half-open window [startMs, endMs); date-range computed once from window bounds; each rotated date file checked; live `audit.ndjson` always checked (it covers today regardless of whether the window endpoint is past midnight).
+- **`spendTrendDaily` calendar-date semantics**: `days: N` returns "last N calendar UTC dates ending today" — NOT "events within a rolling N×86400-ms window" (which would span N+1 distinct UTC dates and produce off-by-one buckets at non-midnight call times). Computed via `for (let i = days-1; i >= 0; i--) dates.push(_utcDateFromMs(now - i*86400*1000));`.
+- **`cacheHitRateWindow` denominator**: hit_rate = hit / (hit + miss). Bypass is intentional non-cacheable (Anthropic cache_control marker), NOT a cache miss; excluding it from the denominator gives a clean cache-effectiveness signal.
+- **Test surface (Suite 23, +27 tests — 544 → 571):**
+  - 23a-1..4: `discoverAuditFiles` (empty dir / live only / live+rotated / non-audit files ignored)
+  - 23b-1..6: `readAuditWindow` (all-coverage / single-day / half-open exclusivity / empty window / missing files / malformed-skip with warn)
+  - 23c-1..4: `aggregateRequests` (counts + status buckets + by_provider; by_owner_tier; median+p95 latency over realistic distribution; invalid windowMs rejection)
+  - 23d-1..4: `topFallbackChains` (sort desc by count; limit truncation; fallback_hops=0 excluded; first_seen/last_seen carried)
+  - 23e-1..3: `spendTrendDaily` (N-day range correctness; populated day breakdown; empty day sparse-fill)
+  - 23f-1..3: `cacheHitRateWindow` (overall + per-provider hit_rate; bypass not in denominator; cache_status=null events excluded)
+  - 23g-1..3: PII guard for `aggregateRequests` / `spendTrendDaily` / `topFallbackChains` + `cacheHitRateWindow` — every output JSON-stringified + scanned for forbidden PII keys
+- **Documentation:** AGENTS.md `lib/audit-query.mjs` new entry; `lib/audit.mjs` note added that D52 extends with daily rotation.
+- **Test count:** 544 → 571 (+27 D49 tests).
+- **Authority:** ADR 0008 § 4 (query API surface) + § 5 (rotation file naming pattern) + § 3 (storage layout); ADR 0007 § 8 (audit ndjson event schema — input data); CLAUDE.md `release_kit overlay phase_rolling_mode` — under Unreleased; standing autopilot grant.
+
+### 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).

 # OLP — Open LLM Proxy
 
-A personal- and family-scale multi-provider LLM proxy. One HTTP endpoint, many subscriptions behind it, automatic routing, automatic fallback, content-addressed caching — so your IDEs and family clients keep working as long as *any* of your subscriptions has quota left.
+A personal- and family-scale multi-provider LLM proxy. One HTTP endpoint, many subscriptions behind it, automatic routing + fallback + content-addressed caching. Your IDEs and family clients keep working as long as **any** of your subscriptions has quota left.
 
-> **Status:** v0.2.0 shipped (2026-05-25) — Phase 1 multi-provider proxy core (v0.1.0 + v0.1.1) + Phase 2 multi-key auth + audit + owner gating + keygen CLI. Phase 3 (Dashboard + audit query layer) is the next milestone. Sections marked _placeholder_ land alongside the relevant phase of work (see [phase plan](#phase-plan)).
+> **Status:** v0.5.1 shipped, 759+ tests. Phase 5 (Quota Probes + Dashboard Enrichment) closed; Phase 6 next. Coming from [OCP](https://github.com/dtzp555-max/ocp)? See [§ Migration from OCP](#migration-from-ocp).

-## Why OLP
+## What you get
 
-On 2026-05-14, Anthropic announced (effective 2026-06-15) that `claude -p`, the Agent SDK, and third-party agent traffic move out of the Pro/Max subscription pool into a separate fixed monthly Agent SDK Credit pool. [OCP](https://github.com/dtzp555-max/ocp), OLP's predecessor, was a proxy around a single CLI — its core assumption was *"subscription = unlimited within rate limits"*. That assumption breaks for Anthropic on the effective date.
+- **OpenAI-compatible** `/v1/chat/completions` endpoint — any IDE that speaks OpenAI (Cline / Continue.dev / Cursor / Aider) plugs in
-
+- **Multi-provider chain** — primary fails / quota dies → automatically falls back to the next provider (anthropic ↔ codex ↔ mistral by default; risk-tier framework guards which ones get enabled)
-The structural response is to stop relying on one provider's subscription terms remaining favourable. OLP spreads risk across multiple providers whose subscriptions still include CLI/programmatic use, routes intelligently between them, and caches aggressively so every request that does spawn a CLI counts.
+- **Content-addressed cache** — repeat requests don't re-spawn the CLI; streaming requests dedup via singleflight tee
-
+- **Multi-key auth** — owner key with full visibility, family-member keys with per-key audit log + per-provider scoping
-OLP is **not**: a commercial multi-tenant SaaS; an enterprise gateway competing with LiteLLM / OpenCode / CLIProxyAPI on breadth; a model-capability router ("route to the smartest model" — you pick the model); a conversation-state store (your client handles that).
+- **Telegram / Discord** `/olp` slash commands (read-only — for "is OLP up?" checks from anywhere)
-
+- **AI-driven self-repair** — `olp doctor --json` emits machine-readable `next_action.ai_executable[]` so a Claude Code / Cursor / Copilot session can fix install issues for you (see [§ Install with your AI](#install-with-your-ai-the-fast-path))
-See [`ALIGNMENT.md`](./ALIGNMENT.md) for OLP's constitution and [`docs/adr/`](./docs/adr/) for the founding ADRs.
+- **Observability** — owner-only `/dashboard` (live Claude.ai-style plan-usage rows / 24h stats / 30d spend trend / top fallback chains)
+- **Plan-usage probe** (Phase 5, v0.5.0) — opt-in per-provider quota probe for Anthropic Pro/Max subscriptions; parses the canonical `anthropic-ratelimit-unified-*` response headers, surfaces 5-hour + 7-day utilization with reset countdowns. See [§ Plan Usage](#plan-usage-live-quota-probe).

-## Quick Start
+## Install with your AI (the fast path)
 
-_placeholder — lands with Phase 1._
+If the manual steps feel like a lot, paste this verbatim into your AI coding assistant (Claude Code / Cursor / Copilot / Aider). It walks you through everything:
 
-Anticipated shape:
+```
+I want to install OLP (Open LLM Proxy) on this machine. The repo is at
+https://github.com/dtzp555-max/olp and ships these tools that you can use:
+
+1. `git clone` the repo to ~/olp
+2. README.md § "Manual install" has the sequenced steps. Follow them in order.
+3. After EACH step, run `node ~/olp/bin/olp.mjs doctor --json` (NOT `npx olp`
+   — the package isn't on npm). Parse the JSON. The `kind` field tells you
+   the state: noop / fresh_install / fix_server / fix_oauth / fix_provider /
+   fix_config.
+4. If `kind != noop`, run the commands listed in `next_action.ai_executable[]`
+   verbatim. Then re-run doctor to verify.
+5. STOP and ask me only when `next_action.human_required[]` is non-empty.
+   That's where I need to do a browser OAuth flow you can't do for me.
+
+The provider CLIs OLP spawns (claude / codex / vibe) need their own one-time
+OAuth — those are the only steps I personally have to do (Claude.ai login,
+ChatGPT login, Mistral API key). Everything else (clone, npm install of the
+provider CLIs, owner-key generation, config.json bootstrap, server start) is
+in your `ai_executable[]` and you should run it without asking.
+
+Begin.
+```
+
+Then sit back and respond when it asks for OAuth confirmation. This pattern works because `olp doctor` is purpose-built for AI consumption — every failure mode has a shell-executable repair command AND a human-required step listed separately.
+
+---
+
+## Manual install (5-10 min)
+
+### 0. Prerequisites
+
+- **Node.js ≥ 18.** Verify: `node --version`
+- **The provider CLIs you want OLP to spawn.** Install whichever you'll actually use:
+
+  | Provider | Install | Subscription |
+  |---|---|---|
+  | `anthropic` (`claude -p`) | `npm install -g @anthropic-ai/claude-code` | Claude Pro/Max (OAuth) |
+  | `openai` (`codex exec`) | `npm install -g @openai/codex` | ChatGPT Plus/Pro (OAuth) or OpenAI API key |
+  | `mistral` (`vibe --prompt`) | follow the `vibe` install docs | Le Chat Pro API key |
+
+  You only need to install the ones you'll route to. Single-provider OLP works fine.
+
+### 1. Clone and verify the test suite
 
 ```bash
-# install
+git clone https://github.com/dtzp555-max/olp.git ~/olp
-npm install -g @dtzp555-max/olp
+cd ~/olp
-
+npm test    # 714+ tests, ~5s, no external deps
-# run setup (writes ~/.olp/config.json, asks which providers to enable)
-olp setup
-
-# start the proxy (default port 3456 — same as OCP if you migrate)
-olp start
-
-# point your IDE at http://localhost:3456/v1/chat/completions with the OLP API key from `olp keys list`.
 ```
 
+(If `npm test` fails here, stop — that means your Node version or the repo state is broken. Don't proceed to step 2.)
+
+### 2. Bootstrap the owner key
+
+The owner key is what you (and `olp-connect`) use to authenticate to OLP. Default config has `auth.allow_anonymous: false`, so you need a key BEFORE the server starts accepting requests.
+
+```bash
+node ~/olp/bin/olp-keys.mjs keygen --owner --name=$(whoami)-laptop
+# Prints the plaintext token ONCE. Copy it now — you can't recover it later.
+# Example: olp_l23-PN46tDljmPATV94-KfOgOBO0Ed8theVjTdAgQoY
+```
+
+Export it so the CLI subcommands can use it:
+
+```bash
+export OLP_API_KEY=olp_l23-PN46...   # paste your real token
+```
+
+(Add to `~/.bashrc` / `~/.zshrc` to persist.)
+
+### 3. Authenticate the providers (one-time OAuth)
+
+Run each provider's own login flow. OLP's anthropic / openai / mistral plugins spawn these CLIs and reuse their cached credentials — OLP itself never touches the OAuth dance.
+
+```bash
+# Anthropic (Claude Pro/Max subscription)
+claude setup-token
+# Opens a TUI / prints a URL. Authorize in browser. Paste the returned code.
+# Result: ~/.claude/.credentials.json
+
+# OpenAI (ChatGPT subscription)
+codex login --device-auth
+# Prints a https://auth.openai.com/codex/device URL + 10-char code.
+# Open URL in browser, enter code, authorize.
+# Result: ~/.codex/auth.json

+## Family / LAN setup
+
+To let other devices on your home network use the same OLP server, you need TWO things:
+
+1. **Bind to the LAN interface** (not just loopback). On the SERVER:
+
+   ```bash
+   OLP_BIND=0.0.0.0 npm start   # or your specific LAN IP, e.g. 192.168.1.10
+   ```
+
+   Default is `127.0.0.1` (loopback only). See [ADR 0011 § Deployment configurations](./docs/adr/0011-anonymous-key-deployment-context.md#deployment-configurations-d76-amendment-2026-05-26) for the trust-context table — **never set `OLP_BIND=0.0.0.0` on a public-internet-facing host** (use a tunnel like Tailscale instead).
+
+2. **Onboard each family member's device** from THEIR machine:
+
+   ```bash
+   # Pinned to a known-good release (recommended — survives GitHub raw CDN cache hiccups):
+   bash <(curl -fsSL https://raw.githubusercontent.com/dtzp555-max/olp/v0.4.4/bin/olp-connect) <olp-host-ip>
+
+   # OR latest from main (use after v0.4.4 + once you trust head):
+   bash <(curl -fsSL https://raw.githubusercontent.com/dtzp555-max/olp/main/bin/olp-connect) <olp-host-ip>
+   ```
+
+   Detects Cline / Continue.dev / Cursor / Aider / OpenClaw locally and writes per-tool config pointing at your OLP host. Requires `python3` on the client. Prompts for the OLP API key — OR, if the server has `auth.advertise_anonymous_key: true` AND a key was created with `olp-keys keygen --anonymous --advertise`, picks the token up from `/health.anonymousKey` (zero out-of-band paste). See [ADR 0011](./docs/adr/0011-anonymous-key-deployment-context.md) for the trusted-LAN-only invariant.

The evaluation logic exists and is tested; only the production data ingestion path is deferred.

-Trigger types, fallback safety, idempotency rules, and the full example config land here when Phase 4 ships. See [ADR 0004 (Fallback Engine Semantics & Safety)](./docs/adr/0004-fallback-engine.md) for the design.
+- **`auth.allow_anonymous`** — default `false`. When false, every request needs a Bearer token; when true, anonymous-tier requests succeed (ADR 0007 § 7). Production posture is `false`.
+- **`auth.owner_only_endpoints`** — list of endpoints that REQUIRE owner-tier auth (non-owner returns 401). The defaults above are minimum sane for production.
+- **`auth.advertise_anonymous_key`** — default `false`. When true (+ `allow_anonymous: true` + a key created with `olp-keys keygen --anonymous --advertise`), `/health.anonymousKey` exposes the plaintext token so `olp-connect <ip>` is zero-config. **Trusted-LAN only** — see [ADR 0011](./docs/adr/0011-anonymous-key-deployment-context.md).
+- **`auth.fallback_detail_header_policy`** — controls `X-OLP-Fallback-Detail` response header emission. `owner_only` (default) only shows tuples to owner identity; debug surface to LAN family without leaking to anonymous.
+- **`providers.enabled`** — flip a provider plugin on. Only enable providers whose CLI you've authenticated; OLP doesn't do its own OAuth.
+- **`routing.chains`** — keyed by the model name your IDE / client requests. Each entry is an ordered list of fallback hops; each hop's `model` is what gets passed to that provider's CLI. F7 fix (D75) — the hop-level `model` field finally overrides the IR's request model during cross-provider fallback.
+- **`routing.soft_triggers`** — parsed and stored but **inert at v0.4.x** — the `quotaStatus()` polling data path is deferred to v1.x per [ADR 0004 Amendment 2](./docs/adr/0004-fallback-engine.md#amendment-2--2026-05-24-soft-triggers-deferred-to-v1x-d22). Startup emits a warn if non-empty so the inert state is visible.
+- **`streaming.heartbeat_interval_ms`** — default `0` (disabled). Set > 0 (e.g. `15000`) to emit SSE keepalive frames during silent windows. Required behind reverse proxies (nginx / Cloudflare Tunnel / Tailscale Funnel) with 60s idle aborts.

+## Plan Usage (live quota probe)
+
+OLP v0.5.0+ surfaces live subscription quota for Anthropic Pro/Max subscribers on the owner-only `/dashboard`. Per-provider rows show 5-hour and 7-day utilization bars with reset countdowns, status badges, representative-claim hints, and a manual refresh button. The panel auto-refreshes every 60 seconds and pauses when the tab is hidden.
+
+![OLP v0.5.0 dashboard — Plan Usage panel with live anthropic quota](./docs/img/dashboard-v0.5.0.png)
+
+### How it works
+
+The probe issues a minimal `POST /v1/messages` to `api.anthropic.com` (max_tokens: 1) using the same OAuth token Claude Code uses for `claude -p`. The body is discarded; only the 13 `anthropic-ratelimit-unified-*` response headers are parsed (5h/7d utilization + reset, status, representative-claim, fallback-percentage, overage status + disabled reason). Results cache for 5 minutes; refresh failures fall back to the previous cache marked `stale: true` while exponential backoff (60s → 3600s) protects against hammering the API.
+
+See [ADR 0002 § Amendment 8](./docs/adr/0002-plugin-architecture.md), [ADR 0012 (Phase 5 charter)](./docs/adr/0012-phase-5-charter-quota-probes-dashboard.md), [ADR 0013 (OAuth READ-ONLY consumption + schema-drift mitigation)](./docs/adr/0013-oauth-read-only-consumption-and-schema-drift.md), and the schema pin at `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`.
+
+### Enabling the probe
+
+The probe is **opt-in** (default off) per ADR 0013 Rule 4 — a fresh OLP install on a machine without OAuth credentials should not bombard `api.anthropic.com` with 401-bound probes. To enable, add to `~/.olp/config.json`:
+
+```json
+{
+  "providers": {
+    "anthropic": {
+      "enabled": true,
+      "quota_probe_enabled": true
+    }
+  }
+}
+```
+
+The probe reads the OAuth token from (in order): `CLAUDE_CODE_OAUTH_TOKEN` env var, `~/.claude/.credentials.json`, macOS Keychain entry `"Claude Code-credentials"`. Make sure Claude Code is logged in (`claude setup-token` or equivalent) before opting in.
+
+`olp doctor` adds a `anthropic.quota_probe_reachable` check when the probe is enabled. The check has `category: 'provider'`, so any failure (401/403 token-expiry, 429 rate-limit, network error) discriminates to `kind: fix_provider`. The `human_steps` recovery recipe inside the check distinguishes the underlying cause (re-login via `claude setup-token` for auth failures vs wait-and-retry for rate-limit) — the discriminator is uniformly `fix_provider` but the actionable text is auth-aware. Successful probes return `status: ok` with the parsed 5h / 7d utilization in the message body; stale-cache returns `status: warn`. Routing an auth-class failure to `kind: fix_oauth` (the other discriminator the framework supports) would require splitting this check across the `provider` / `auth` boundary — deferred to v1.x if `olp doctor` consumers report the ambiguity.
+
+### Provider coverage
+
+| Provider | Live quota probe | Path |
+|---|---|---|
+| `anthropic` | ✅ Live — 13 fields via `anthropic-ratelimit-unified-*` headers | This section |
+| `openai` (codex) | ❌ Not available — `openai/codex` CLI has no public quota API | Falls back to audit-derived request counts |
+| `mistral` | ❌ Not implemented at v0.5.0 — no public quota endpoint accessible to Vibe / Le Chat member / La Plateforme API keys. Mistral's Admin API does expose billing / usage queries but is gated to org-admin scope and out of scope for OLP family-tier deployment. | Falls back to audit-derived request counts |
+
+If Mistral ever publishes a usage endpoint, `lib/providers/mistral.mjs` DL-7 marks the re-entry point.
+
+### Schema-drift protection
+
+Claude Code v2.1.x is distributed as a compiled native binary (Mach-O on macOS, ELF on Linux) — the OCP-era "grep `cli.js`" verification no longer applies. OLP's replacement protocol (ADR 0013 § Rule 5):
+
+1. `strings` over the platform-specific claude-code binary captures all hardcoded header names the binary expects.
+2. A live `POST /v1/messages` against `api.anthropic.com` with valid OAuth captures what the server actually emits today.
+3. Diff path 1 vs path 2 → the actionable schema delta.
+
+This is re-run at every major `claude --version` bump (next trigger: v2.x → v3.x), at the Annual Alignment Audit (14 May), and whenever `olp doctor anthropic.quota_probe_reachable` returns an unexpected status code. The current pinned schema (13 fields, `2026-05-26`) lives in `models-registry.json` under `quota_probe.schema_version`.

+OLP ships [`olp-plugin/`](./olp-plugin/) as a native OpenClaw gateway plugin. After install, family members get a read-only `/olp` slash command on whichever chat surfaces OpenClaw exposes (Telegram + Discord today).
+
+**Install:**
+
+```bash
+# Option A — OpenClaw CLI
+openclaw plugins install /path/to/olp/olp-plugin/
+
+# Option B — symlink (equivalent)
+mkdir -p ~/.openclaw/extensions/
+ln -s /path/to/olp/olp-plugin/ ~/.openclaw/extensions/olp
+```
+
+**Configure:** edit `~/.openclaw/openclaw.json` and set the plugin's `apiKey` to an owner-tier OLP token created with:
+
+```bash
+npx olp-keys keygen --owner --name=openclaw-bot
+```
+
+Use a dedicated bot key — not the maintainer's personal owner key — so revocation is scoped.
+
+```json
+{
+  "plugins": {
+    "olp": {
+      "proxyUrl": "http://127.0.0.1:4567",
+      "apiKey": "olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+    }
+  }
+}
+```
+
+**Restart:** `openclaw gateway restart`.
+
+**Use:** `/olp status`, `/olp usage`, `/olp models`, `/olp health`, `/olp cache`, `/olp providers`, `/olp doctor`, `/olp help`.
+
+**Read-only by design.** Mutating subcommands (`keygen`, `revoke`, `restart`, `logs`) are deliberately NOT exposed via chat — those are SSH-only via the local `olp` CLI. See [`olp-plugin/README.md`](./olp-plugin/README.md#what-you-can-not-do-from-chat-by-design) for the rationale.

 Behaviors that work correctly at personal/family scale but have ratified follow-ups for a v1.x sprint. Single landing page: [`docs/v1x-roadmap.md`](./docs/v1x-roadmap.md).
 
-- **Streaming-path singleflight not implemented.** The cache layer's D4 singleflight (one spawn per identical concurrent request) is fully wired on the buffered path but NOT on the streaming path. N concurrent identical streaming requests at v0.1 will each spawn their own CLI process. Design ratified in [ADR 0005 Amendment 8](./docs/adr/0005-cache-cross-provider.md); implementation tracked via [issue #16](https://github.com/dtzp555-max/olp/issues/16) and [v1.x roadmap #1](./docs/v1x-roadmap.md). At family scale this is observably fine — every caller still receives the correct response; the cost is N CLI processes instead of one.
+- **Streaming-path singleflight ✅ shipped (D57 + D58, 2026-05-25).** `cacheStore.getOrComputeStreaming(...)` mirrors the buffered-path `getOrCompute` and resolves the TOCTOU window between peek and spawn ([issue #16](https://github.com/dtzp555-max/olp/issues/16)). Two concurrent identical streaming requests share one CLI spawn via tee fan-out; late joiners receive accumulated replay + the live tail; per-client backpressure (`PER_CLIENT_QUEUE_CAP=1MB`) protects against slow consumers; full-disconnect aborts the source CLI via AbortController. New `X-OLP-Streaming-Inflight: source | attached` header annotates the role. New `cache_status: 'streaming_attached'` audit value tracks the singleflight win. Authority: [ADR 0005 Amendment 8](./docs/adr/0005-cache-cross-provider.md), v1.x roadmap #1.
 - **Soft triggers configured but inert.** `routing.soft_triggers` in `~/.olp/config.json` is honored by the engine's evaluation logic but `quotaStatus()` polling is not wired (ADR 0004 Amendment 2). A startup warning fires if the field is non-empty so the inert state is visible.
-- **Multi-key auth + owner gating + keygen CLI all shipped (D44 + D45 + D46 + D47); Phase 2 close pending.** `lib/keys.mjs` core shipped at D44; `server.mjs` invokes `validateKey` per request, filters the chain by `providers_enabled`, fires `touchLastUsed` post-response, and appends an audit row to `~/.olp/logs/audit.ndjson` for each `/v1/*` request (D45). At D46: `/health` payload trimmed for non-owner (returns `{ ok, version }` when `owner_only_endpoints` includes `/health`); `X-OLP-Fallback-Detail` emission gated by `fallback_detail_header_policy` (`owner_only` default suppresses for non-owner; `'all'` opts back into v0.1.1 behaviour; `'none'` suppresses entirely). At D47: keygen CLI shipped at `bin/olp-keys.mjs` — `npx olp-keys keygen --owner` produces an owner key (plaintext printed once); `npx olp-keys list` / `revoke` for lifecycle management. Phase 2 functional scope is complete; close to v0.2.0 is maintainer-triggered per CLAUDE.md `release_kit.phase_close_trigger`. Tracked in [v1.x roadmap #2](./docs/v1x-roadmap.md).

 ## Migration from OCP
 
+OLP is OCP's successor. 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 $100/month Agent SDK credit pool — invalidating OCP's foundational assumption (*"subscription = unlimited within rate limits"*) for its only provider. OLP's structural response is to spread risk across multiple subscriptions whose CLI/programmatic use remains in their main subscription pool, with intelligent fallback when one runs out.
+
+Beyond the billing trigger, OLP is intentionally NOT a commercial multi-tenant SaaS (LiteLLM / OpenRouter / Portkey already serve that market with funding + SOC2), NOT an enterprise gateway competing on provider breadth, NOT a model-capability router ("route to the smartest model" — you pick the model in `routing.chains`), and NOT a conversation-state store (your client manages its own context). See [ADR 0001](./docs/adr/0001-project-founding.md) for the founding decision and [`ALIGNMENT.md`](./ALIGNMENT.md) for the constitution that governs every plugin / IR / entry-surface change.

+olp-connect — Connect this machine to a remote OLP (Open LLM Proxy)
+
+Configures OPENAI_BASE_URL + OPENAI_API_KEY in your shell rc file (and macOS
+launchctl env / Linux systemd user env), then detects installed IDEs (Cline,
+Continue.dev, Cursor, Aider, OpenClaw, Claude Code) and prints / writes the
+provider-specific configuration each needs.
+
+Usage:
+  olp-connect <host-ip> [options]
+  olp-connect --help
+  olp-connect --version
+
+Options:
+  --port PORT       Port OLP listens on (default: 4567 — OLP v0.4.0+ default;
+                    set 3456 if connecting to a pre-D60 OLP install)
+  --key API_KEY     OLP API key (from `olp-keys keygen` on the server). When
+                    omitted, the script reads /health.anonymousKey (if the
+                    server opted in via auth.advertise_anonymous_key=true) or
+                    prompts interactively.
+  --no-system-env   Skip macOS launchctl setenv / Linux systemd env writes;
+                    only update shell rc files.
+  --dry-run         Print everything the script would do without modifying
+                    any file or setting any env var.
+  --version         Print version and exit
+  --help, -h        Show this help
+
+Examples:
+  olp-connect 192.168.1.10
+  olp-connect 192.168.1.10 --port 8080
+  olp-connect 192.168.1.10 --key olp_AbcDef1234...
+  olp-connect 100.64.0.5 --dry-run
+
+Requires:
+  bash, curl, python3 (for /health JSON parsing)
+
+Exit codes:
+  0   success
+  1   bad arguments / unknown flag / missing required value
+  2   connectivity or auth failure / smoke test failure
+
+Authority: ADR 0010 § Phase 4 D68-D70; ADR 0011 (anonymous-key trusted-LAN
+invariant — when --key is auto-resolved from /health.anonymousKey, this
+deployment MUST be on a trusted LAN).

+ *   --proxy-url=<url>      override resolved proxy URL
+ *   --olp-home=<path>      override ~/.olp
+ *
+ * URL resolution:
+ *   OLP_PROXY_URL env (full URL)  →  http://127.0.0.1:${OLP_PORT || 4567}
+ *
+ * Auth (Bearer token) resolution:
+ *   1. OLP_API_KEY env
+ *   2. OLP_OWNER_TOKEN env (synthetic env-owner per ADR 0007 § 9.4)
+ *   3. Most recently used active owner-tier key from listKeys()    ← plaintext NOT recoverable from disk
+ *
+ *   Note: the third option only works during the same session in which `olp-keys
+ *   keygen --owner` was run if the operator captured the token + set OLP_OWNER_TOKEN.
+ *   listKeys() returns manifests; manifest.token_hash is one-way. The CLI therefore
+ *   reports "no owner token available" + remediation instructions if env vars are
+ *   absent — it does NOT try to crack the hash.

+ * Exit codes:
+ *   0 = success
+ *   1 = bad usage / unknown subcommand
+ *   2 = network or HTTP error (4xx/5xx)

+  OLP Dashboard — Phase 5 / D82
+  ------------------------------
+  Multi-panel owner-only dashboard per ADR 0008 § 6.
+
+  Panels:
+    0. Plan Usage (new D82 — Claude.ai-style per-provider rows; quota_v2; 1-min refresh)
+    1. Per-provider quota / credit pool (legacy; kept for graceful fallback when quota_v2 absent)
+    2. Per-provider 24h request count + cache hit rate + fallback rate (30s refresh)
+    3. 30-day spend trend (SVG sparkline; per-provider in tooltip) (30s refresh)
+    4. Top 10 fallback chains by trigger count (30s refresh)
+
+  Refresh cadence:
+    - Plan Usage panel: 60s (separate timer; visibilityState-guarded per ADR 0012 D82)
+    - Other panels: 30s (original poll cadence; paused when tab hidden)
+
+  Authority:
+    - ADR 0008 § 6 — dashboard layout + owner-only_block
+    - ADR 0012 D82 — quota_v2 Claude.ai-style restructure
+    - v1.x roadmap #8 — closed by this D-day
+
+  No build step, no framework, no external dependencies. Vanilla JS +
+  fetch + DOM render. Owner-only_block: anonymous / guest / no-auth all
+  receive 401 — non-owner identities will see an error banner.

Both qualifiers were appropriate for the *commercial* path ADR 0005 was contemplating. OLP is not commercial — it is personal- and family-scale, shares the maintainer's own subscription quota across family clients, and explicitly spawns provider CLIs (it is precisely the spawn-binary architecture that delivers the "subscription quota maximization" value proposition spec §1 names).
 - OLP is therefore not the commercial pivot ADR 0005 endorsed. It is a personal-use re-architecture of the proxy-CLI pattern, which ADR 0005 did not contemplate. The supersession is honest about this gap.

Per spec §7, OCP enters maintenance mode when OLP v0.1 ships. ~~The two projects do not parallel-run in production (port-3456 conflict, single launchd service slot, one set of credentials per machine).~~ **Amended at D60 (2026-05-26, ADR 0010 Phase 4 charter):** the port-conflict assumption is lifted. OLP's default port moved `3456 → 4567` at v0.4.0 so OCP (which stays on 3456) and OLP can co-host on the same machine during a transition window. Launchd label collision **will be** avoided via `dev.olp.proxy` (OLP plist generation lands at Phase 4 close per ADR 0010 D64–D70; not on disk at D60) vs `dev.ocp.proxy` (OCP, already shipped). Credentials remain per-project (`~/.ocp/` vs `~/.olp/`). Co-host is explicit-opt-in, not the recommended steady state.
 
 OCP ADR 0005 receives a header amendment on merge of this ADR: *"Superseded in part by OLP — see https://github.com/dtzp555-max/olp ADR 0001 for the narrow scope of the supersession (single-provider-sufficiency premise only; ADR 0005's commercial / BYOK / no-spawn recommendations are not adopted)."* The body of ADR 0005 is otherwise untouched.

+### Amendment 8 — 2026-05-26: Permit `quotaStatus()` direct-API access (READ-ONLY exemption) for plan-usage probes (D79–D80 — Phase 5)
+
+- **Context:** ADR 0012 (Phase 5 charter) opens 2026-05-26 to port OCP's plan-usage probe (`ocp/server.mjs:842-1109`) into `lib/providers/anthropic.mjs:quotaStatus()`. The probe calls `POST https://api.anthropic.com/v1/messages` directly with an OAuth bearer and parses `anthropic-ratelimit-unified-*` response headers. This violates the plugin contract's implicit assumption that ALL provider interaction goes through `spawn` (the binary CLI). `ALIGNMENT.md` Rule 2 (provider-CLI-as-authority) further constrains plugins to operations the provider CLI itself performs. The OCP-derived plan-usage probe satisfies neither of these — it bypasses `claude -p` and hits the public API directly. **Without an explicit exemption Amendment, D80 is unalignable.**
+- **Why the exemption is sound:** The probe is strictly **READ-ONLY** (one `POST /v1/messages` with `max_tokens: 1`; the response body is discarded; only response headers are parsed) AND **subscription-scope** (the OAuth bearer is the same one Claude Code uses for `claude -p`; no extra grant is requested) AND **idempotent** (probe failure returns `null`, never throws to a caller). The "what authority backs this?" answer is: Anthropic's CLI internally makes the same `/v1/messages` call (verified 2026-05-26 by `strings` on the compiled binary — see `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`); the probe is mirroring an established CLI behaviour rather than introducing a new wire format. Under `ALIGNMENT.md` Rule 2, mirroring observed CLI behaviour is permitted; the Rule's intent is "don't invent wire formats Anthropic's CLI does not perform", which the probe respects.
+- **Change — extend the Provider contract description:**
+  - `quotaStatus(authContext): { quotaInfo }` is now permitted to call provider HTTP APIs directly, subject to **all three** constraints:
+    1. **READ-ONLY** — the API call must not mutate provider-side state. POST is acceptable when the response is what's needed (Anthropic returns ratelimit headers on `POST /v1/messages`); the request body MUST minimise side-effects (`max_tokens: 1`, dummy `messages`).
+    2. **Subscription-scope reuse** — the credentials used MUST be the same auth artifact the spawn path already reads via `readAuthArtifact()`. No new OAuth grant, no new API-key registration, no separate scopes.
+    3. **Idempotent failure** — if the probe fails for any reason (network error, 401, 429, schema parse failure), the function returns a structured shape (`{ probe_status: 'unreachable', failure: { kind, message, backoff_until? } }` since v0.5.1; see ADR 0013 Rule 6 + ADR 0008 Amendment 2) rather than throwing. The caller (server.mjs / dashboard / `olp usage` CLI) gracefully degrades. At v0.5.0 the failure shape was the literal value `null`; v0.5.1 refined this to a structured shape so operators can distinguish auth failures from rate-limit failures from network failures from in-backoff stale-cache. The substantive idempotent-failure constraint (no throw to caller) is unchanged.
+  - `healthCheck()` and other contract methods are NOT extended by this Amendment. Only `quotaStatus()` may make direct API calls. A plugin that wants live data for any other contract method must continue to use `spawn` or `readAuthArtifact`.
+  - The probe MUST cache its result. Recommended TTL: 5 minutes (mirrors OCP `USAGE_CACHE_TTL`). Tighter TTLs (e.g. dashboard's 1-minute refresh) are served from the cached value if fresh; cache miss triggers a real probe.
+  - The probe MUST implement exponential backoff on refresh failures: minimum 60s, maximum 3600s (mirrors OCP `OAUTH_REFRESH_MIN_BACKOFF` / `OAUTH_REFRESH_MAX_BACKOFF`). Tight loop on failure has historically burned through Anthropic's rate limit in seconds (OCP institutional lesson 2026-04).
+  - The probe MUST be opt-in via `~/.olp/config.json` (`providers.<name>.quota_probe_enabled: true`; default `false`). Reasoning: a fresh OLP install on a machine without OAuth credentials should not bombard `api.anthropic.com` with 401-bound probes; the operator opts in once the credentials are configured.
+- **What this Amendment does NOT permit:**
+  - Mutating API calls (e.g. POST/PATCH/DELETE that change provider-side state). Still forbidden.
+  - API calls for any contract method other than `quotaStatus()`. `spawn` / `healthCheck` / `doctorChecks` / `estimateCost` / `models` / `hints` / `name` / `displayName` / `auth` remain spawn-and-filesystem-only.
+  - Per-provider new auth grants. The probe uses the spawn path's existing credentials.
+  - Bypassing the alignment.yml blacklist. The hallucinated `/api/oauth/usage` token stays blacklisted; the probe uses `/v1/messages` (real endpoint).
+  - **API calls to endpoints not explicitly enumerated by the companion ADR 0013 § Rule 2.** Amendment 8 permits the *kind* of call (READ-ONLY direct API for quota probing); ADR 0013 Rule 2 enumerates *which specific endpoint* is permitted. A future reader of Amendment 8 alone should NOT infer that any READ-ONLY/idempotent endpoint is fair game — the per-endpoint containment is locked to ADR 0013. Re-opening per-endpoint scope requires an ADR 0013 amendment, not a new plugin-level interpretation of Amendment 8.
+- **Backwards compatibility:** Plugins whose `quotaStatus()` still returns `null` (mistral at v0.5.0 pending D84 audit, codex permanently per Phase 5 charter) are NOT affected. No existing behaviour changes for them.
+- **Authority cited at the implementation:** D80 commit cites this Amendment + `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md` + `Claude Code v2.1.x § OAuth bearer + ratelimit-unified headers` + live-probe transcript from 2026-05-26 in the commit body. ALIGNMENT.md Rule 1 + Rule 5 (CI) both satisfied.
+- **Tests:** Suite 38 (Phase 5 D83) covers the probe: mock HTTP server returning all 13 `anthropic-ratelimit-unified-*` headers; assert parse correctness for each; assert 5min cache; assert 60s-3600s exponential backoff on simulated 429; assert stale-cache-on-failure. At v0.5.0 stale-failure returned `{ stale: true, ... }` with `null` reserved for no-cache failures; v0.5.1 refined the return contract — `null` is now reserved STRICTLY for opt-in-off, and all failure modes (auth / rate-limit / schema-drift / network / no-creds) return `{ probe_status: 'unreachable' | 'stale', failure: {...} }`. See `test-features.mjs` Suite 38 (38u/38v/38w added for the v0.5.1 hotfix regression coverage of F1 / F2 / F3 per codex review).
+- **Procedural mechanism:** Iron Rule 11 (IDR) — this Amendment, ADR 0012 (Phase 5 charter), and ADR 0013 (OAuth READ-ONLY consumption rules) land together at D79 as a single coupled commit. Reviewing them separately cannot verify consumer-producer alignment. Iron Rule 10 fresh-context reviewer per CLAUDE.md hard requirement #3.
+
+### Amendment 7 — 2026-05-26: Add OPTIONAL `doctorChecks()` to the Provider contract (D67 — Phase 4 operator UX)
+
+- **Context:** ADR 0010 § Phase 4 D64-D67 ships `bin/olp.mjs` operator CLI + `olp doctor` framework. `olp doctor` runs a set of `Check` objects (id / category / async `run()` returning `{ status, message, evidence? }`) and discriminates the next remediation step via a `kind` field (`noop` / `fix_server` / `fix_oauth` / `fix_provider` / `fresh_install`). The framework needs per-provider checks so a user with a broken `claude` install gets a different fix recipe than a user with a broken `vibe` install. Hardcoding the recipes in `bin/olp.mjs` would re-introduce the kind of per-provider knowledge drift that ADR 0002 § Decision exists to prevent — when a new provider plugin lands, the operator CLI would have to be edited too.
+- **Change — add to Provider contract:**
+  - Introduce **OPTIONAL** `doctorChecks()` returning `DoctorCheck[]` where each `DoctorCheck` has the shape:
+    - `id: string` — unique per check, conventionally `<provider>.<probe-name>` (e.g. `anthropic.cli_available`, `anthropic.oauth_token_present`).
+    - `category: 'provider'` — fixed for plugin-contributed checks. The framework reserves `'server'`, `'auth'`, `'config'`, `'system'` for built-in checks.
+    - `async run(): { status: 'ok' | 'fail' | 'warn', message: string, evidence?: { fix_commands?: string[], human_steps?: string[], reference?: string } }` — runs the probe. `status: 'fail'` makes `olp doctor` exit non-zero and contributes to the `kind: fix_provider` discriminator; `evidence.fix_commands[]` is concatenated into `next_action.ai_executable[]` and `evidence.human_steps[]` into `next_action.human_required[]`.
+- **Backwards compatibility:** Plugins that omit `doctorChecks()` contribute zero provider checks. Their healthCheck() return value continues to flow through `/health.providers.status.<name>` exactly as today. No existing plugin behaviour changes; no existing test breaks. `validateProvider` in `lib/providers/base.mjs` is updated to type-check `doctorChecks` only when present (must be a function); absence is allowed.
+- **What `doctorChecks()` is for vs. what `healthCheck()` is for:**
+  - `healthCheck()` answers "is this provider currently usable?" — checked at the request-execution layer; output feeds `/health` and per-request retry decisions.
+  - `doctorChecks()` answers "if this provider is broken, what specific actionable steps fix it?" — checked at the operator layer; output feeds `olp doctor` + the `next_action.ai_executable[]` repair templates that a downstream AI agent can paste-and-run.
+- **Suggested probe set (per plugin):**
+  - `<provider>.cli_available` — spawn `<bin> --version` with short timeout (≤3s); fail → fix_commands include install instruction.
+  - `<provider>.<auth-artifact>_present` — check whether the auth file / env var the plugin's `readAuthArtifact()` reads is populated; fail → human_steps include the login command (which usually requires browser interaction and so cannot be in `ai_executable[]`).
+- **Authority:** ADR 0010 § Phase 4 D64-D67 (this is the addition called out by that charter). No provider CLI doc citation needed — `doctorChecks()` is an internal contract field. Implementation lands in D67 (this PR): `lib/providers/anthropic.mjs`, `lib/providers/codex.mjs`, `lib/providers/mistral.mjs` each gain a `doctorChecks()` method covering `cli_available` + `<auth-artifact>_present`.
+- **Tests:** Suite 32 (`bin/olp.mjs` CLI smoke) and Suite 33 (`olp doctor` framework) in `test-features.mjs` cover the contract amendment. Suite 33 specifically asserts: (a) a plugin without `doctorChecks()` contributes no provider checks (default behaviour), (b) a plugin with a failing `doctorChecks()` probe triggers `kind: fix_provider` and propagates its `evidence.fix_commands[]` into `next_action.ai_executable[]`, (c) all-passing checks yield `kind: noop`.
+- **Procedural mechanism:** CC 开发铁律 v1.6 § 11 (IDR) — the contract amendment, the plugin implementations, the doctor framework, and the CLI scaffold are tightly coupled. They land as a single PR (D64-D67 bundle) because reviewing them separately cannot verify that consumer + producer line up. Iron Rule 10 fresh-context reviewer per CLAUDE.md hard requirement #3.

+## Amendments
+
+### Amendment 2 — 2026-05-27: v0.5.1 quota_v2 richer failure-mode shape (codex finding F3)
+
+**Scope:** v0.5.1 hotfix extends `ProviderQuotaEntry` and `aggregateProviderQuota()` to surface richer failure-mode detail, addressing codex review finding F3 (operator cannot distinguish failure modes from the `unavailable` catch-all). Authority: ADR 0013 Rule 6 + codex review findings F1–F3.
+
+#### 1. Extended `ProviderQuotaEntry` shape
+
+```js
+{
+  provider: string,
+  // v0.5.1: 'unreachable' added (probe enabled, creds present, but no cache + probe failed)
+  status: 'live' | 'stale' | 'unreachable' | 'unavailable',
+  reason?: string,           // only when status === 'unavailable' (no API or disabled)
+  schema_version: string|null,
+  last_fresh_at: number|null,
+  utilization: { '5h': number|null, '7d': number|null } | null,
+  reset: { '5h': number|null, '7d': number|null, overall: number|null, overage: number|null } | null,
+  representative_claim: string|null,
+  fallback_percentage: number|null,
+  overage: { status: string|null, disabled_reason: string|null } | null,
+  raw_available: boolean,
+  // v0.5.1 (F3 — ADR 0013 Rule 6):
+  failure: { kind, message, backoff_until? } | null,
+  failure_kind: 'no_credentials'|'auth_failed'|'rate_limited'|'schema_drift'|'network'|'other' | null,
+  // Note: 'opt_in_off' is NOT in this enum — when probe is opted out, the row's status
+  // is 'unavailable' (not 'unreachable'); failure_kind stays null. Distinguishing
+  // "user opted out" from "provider has no API" requires reading config separately.
+  backoff_until: number | null,  // epoch-ms when next probe attempt is allowed
+}
+```
+
+Status semantics:
+- `'unavailable'` — probe disabled (`quota_probe_enabled: false`) OR provider has no public quota API (codex, mistral). `failure`, `failure_kind`, `backoff_until` are null.
+- `'live'` — probe succeeded within TTL. `failure` is null.
+- `'stale'` — probe failed but stale cache exists. `failure.kind` describes why the last probe failed. `last_fresh_at` is the epoch of the last successful probe. `backoff_until` tells when the next attempt is scheduled.
+- `'unreachable'` (new) — probe enabled + creds present (or missing!) but no cache available + probe failed. `failure.kind` distinguishes: `no_credentials`, `auth_failed`, `rate_limited`, `schema_drift`, `network`, `other`. `utilization` and `reset` are null (no data).
+
+#### 2. `quotaStatus()` v0.5.1 return contract
+
+`null` is now RESERVED for `quota_probe_enabled: false` only. All other failure paths return a structured shape:
+
+```js
+null                  // ONLY: opt-in off
+{ probe_status: 'live', ... }    // cache fresh
+{ probe_status: 'stale', ..., failure: { kind, message, backoff_until } }  // cache stale + backoff
+{ probe_status: 'unreachable', source, schemaVersion, failure: { ... } }   // no cache + failed
+```
+
+The `stale: boolean` field is retained for backwards-compat (`stale: false` on live, `stale: true` on stale). New code should use `probe_status`.
+
+#### 3. `dashboard.html` unreachable rendering
+
+A new CSS class `.provider-row.unreachable` (red border + light red background) and `.unreachable-reason` text style handle the new status. `failure.message` and `failure_kind` are surfaced as a short text line under the provider badge. `failure.backoff_until` renders a "backoff active: Xs remaining" note if within window.
+
+#### 4. Authority
+
+- ADR 0013 Rule 6 (failure transparency mandate)
+- Codex review findings F1 (doctor bypass), F2 (200+empty-headers → schema_drift), F3 (failure-mode collapse)
+- v0.5.1 hotfix PR

+
+### Amendment 1 — 2026-05-26: D81 Phase 5 quota_v2 shape + aggregateProviderQuota()
+
+**Scope:** D81 (Phase 5 / ADR 0012 D81) extends the audit-query layer and dashboard-data endpoint to surface the new per-provider quota shape introduced by D80 (`lib/providers/anthropic.mjs:quotaStatus()`). This amendment documents the three new interfaces.
+
+#### 1. `models-registry.json` — new `quota_probe` top-level key
+
+D81 adds a `quota_probe` key at the root of `models-registry.json` per ADR 0013 Rule 5 (schema_version in registry so downstream consumers can detect schema drift):
+
+```json
+{
+  "quota_probe": {
+    "schema_version": "2026-05-26",
+    "anthropic": {
+      "source": "anthropic-ratelimit-unified-headers",
+      "endpoint": "https://api.anthropic.com/v1/messages",
+      "fields_pinned": [ ...13 field names... ]
+    }
+  }
+}
+```
+
+`fields_pinned` is load-bearing: if Anthropic adds/renames a header in a future CLI version, dashboard consumers comparing field-presence against this list can flag "schema drift detected" per the ADR 0013 Rule 5 drift-detection runbook. This field must be updated alongside the parser whenever a drift event occurs.
+
+`lib/providers/anthropic.mjs` reads `quota_probe.schema_version` from the registry at call time (via `_resolveSchemaVersion()`) with the module-level `QUOTA_SCHEMA_VERSION` constant as fallback. No hard dependency on the registry — the constant is the safety net.
+
+#### 2. `lib/audit-query.mjs` — new `aggregateProviderQuota()` export
+
+```js
+export async function aggregateProviderQuota({
+  providers,           // Map<name, plugin> or plain object
+  getQuotaStatus,      // optional injectable getter (name) => Promise<shape|null>
+}): Promise<Array<ProviderQuotaEntry>>
+```
+
+For each provider, calls `quotaStatus()` (already cached at the plugin layer per ADR 0013 Rule 3) and normalizes to the `ProviderQuotaEntry` shape:
+
+```js
+{
+  provider: string,
+  status: 'live' | 'stale' | 'unavailable',
+  reason?: string,              // only when status === 'unavailable'
+  schema_version: string|null,
+  last_fresh_at: number|null,   // epoch-ms of last successful probe
+  utilization: { '5h': number|null, '7d': number|null } | null,
+  reset: {
+    '5h': number|null, '7d': number|null,
+    overall: number|null, overage: number|null,
+  } | null,
+  representative_claim: string|null,
+  fallback_percentage: number|null,
+  overage: { status: string|null, disabled_reason: string|null } | null,
+  raw_available: boolean,
+}
+```
+
+Providers returning `null` from `quotaStatus()` (codex, mistral — no public quota API; or probe disabled) produce `{ status: 'unavailable', reason: 'no public quota api or probe disabled', ...null fields }`.
+
+Providers whose `quotaStatus()` throws produce `{ status: 'unavailable', reason: <error.message>, ...null fields }`.
+
+This function does NOT scan ndjson files; it calls live provider plugins. It is audit-query-adjacent (normalized query shape for the dashboard layer) but not audit-derived. Query model remains Lane 2 = A (in-memory, no SQLite).
+
+#### 3. `/v0/management/dashboard-data` and `/v0/management/quota` — new `quota_v2` field
+
+Both endpoints now return TWO quota keys:
+
+- **`quota`** (legacy, unchanged): `Array<{ provider, ...rawQuotaStatus, available }>`. Kept for backwards compatibility with the existing `dashboard.html` (D82 will switch consumers to `quota_v2`).
+- **`quota_v2`** (D81 new): `Array<ProviderQuotaEntry>` — the normalized shape from `aggregateProviderQuota()` above. This is what D82's enriched dashboard UI will consume.
+
+Both fields are computed from the same underlying `quotaStatus()` call. The legacy `quota` key calls `quotaStatus()` independently from `quota_v2`; since the probe is cached at the plugin layer (ADR 0013 Rule 3), the double call incurs no extra API requests.
+
+**Deprecation timeline:** the legacy `quota` key is deprecated as of D81. Target removal: v1.0.0 or when D82 completes the dashboard migration (whichever comes first). Removal requires a separate PR with a CHANGELOG entry.
+
+#### 4. Failure handling
+
+`aggregateProviderQuota()` never throws to the dashboard endpoint. Per-provider failures are absorbed as `{ status: 'unavailable', reason: <error> }` entries. If `aggregateProviderQuota()` itself throws (implementation bug), `handleManagementDashboardData` and `handleManagementQuota` catch the error, log `dashboard_data_quota_v2_failed` / `management_quota_v2_failed`, and return `quota_v2: []` so the rest of the payload is unaffected.

+
+## 1. Context
+
+OLP v0.2.0 ships per-key audit ndjson at `~/.olp/logs/audit.ndjson` (ADR 0007 § 8) but provides no aggregate query surface or visualization. The audit file grows unbounded, and operators must `tail`/`grep` to observe basic facts ("which provider served the most requests today", "what's my cache hit rate", "how often did the chain fall back to OpenAI"). Phase 3 closes this gap with:
+
+1. **`lib/audit-query.mjs`** — an in-memory aggregator that scans `~/.olp/logs/audit-*.ndjson` files in a configurable time window and returns shaped summaries.
+2. **`server.mjs` `/v0/management/*` endpoints** — three owner-only JSON endpoints exposing the aggregate data: `/v0/management/dashboard-data`, `/v0/management/quota`, `/cache/stats`.
+3. **`dashboard.html`** — a single static HTML file served from `/dashboard` (owner-only) that fetches the JSON endpoints, renders 4 panels, and polls every 30s.
+4. **Daily audit rotation** — at UTC midnight (or on first append after a UTC-date change), the live `audit.ndjson` is renamed to `audit-YYYY-MM-DD.ndjson` and a fresh `audit.ndjson` opens. Cross-file queries handle the rolling 30-day window.
+
+Phase 3 deliberately **does not** add a build step, a database, or per-key UI write surface. The first three are out of scope (Option 3 hybrid is § 13's forward path; SQLite has a Node-baseline blocker per § 11). The last is a security surface that warrants a separate review pass (Phase 4+).
+
+Phase 3 is the natural home for OCP's `dashboard.html` port (v0.1 spec § 4.6 — "Port OCP's `dashboard.html` with multi-provider support"). OCP's dashboard was single-provider; OLP's is multi-provider, which is the substantive change. The HTML structure is otherwise lifted.
+
+---
+
+## 2. Decision
+
+The five lanes above are normative. The deviation lattice they sit in:
+
+| Lane | Pinned | Rejected (why) |
+|---|---|---|
+| **1. Tech stack** | Static HTML + vanilla JS + fetch | SSR (Node template literals) — adds server-side render path; CSP harder. SPA — adds build step, violates ethos. |
+| **2. Query model** | In-memory scan of `audit-*.ndjson` per request | SQLite indexed mirror — touches ADR 0007 § 13 migration → engines bump prerequisite. In-memory rolling aggregate — complex (per-write incremental + window expiry), correctness risk. |
+| **3. Rotation** | Daily UTC rotation (`audit-YYYY-MM-DD.ndjson`) | No rotation — single file grows unbounded at family scale ~10–100 lines/day but a year is ~10–50k lines, still ok but no natural query unit. Size-based (100MB / keep 5) — equivalent complexity, query range less intuitive. |
+| **4. Refresh** | Page poll every 30s | SSE push — adds server-side subscriber state; not justified at family scale. Static-at-load — UX too poor. |
+| **5. Dashboard scope** | Full per spec § 4.6 | Minimal (quota + cache + fallback only) — spec is already drafted; full is ~1 D-day more for trend + top-chains panels. Plus key-mgmt UI — security surface delta, Phase 4+. |
+
+**Phase 3 does not** introduce: a database, a build step, an SPA framework, SSE for dashboard, or web-side key management. Each is a future-phase concern (Option 3 hybrid; SSE for dashboard if poll latency becomes pain; key-mgmt UI after a security review pass).

+  audit-2026-05-22.ndjson
+  ...
+```
+
+Files are append-only (no in-place edits). Rotation atomically renames the live file and opens a fresh one. All files have mode 0600; the `logs/` directory is 0700.
+
+**Retention policy at v0.3.0:** unbounded by default (operator manages disk). A Phase 3+ amendment may add automatic retention (`olp_audit_max_days` config) once an observed operational need exists.
+
+---
+
+## 4. Audit query layer (`lib/audit-query.mjs`)
+
+A new module that reads the rotated + live audit files in a date range and returns aggregate summaries. Per-call O(N) where N = total lines in the date range (family scale: thousands per day = trivial).
+
+### 4.1 Public API
+
+```js
+// Read all audit lines in [startMs, endMs); returns iterator of parsed events.
+// Skips malformed lines (logs warn) so a corrupted day doesn't kill the query.
+export function* readAuditWindow({ startMs, endMs, olpHome }): Iterator<AuditEvent>;
+
+// Aggregate request shape over a window. Returns:
+//   {
+//     window: { startMs, endMs },
+//     request_count, status_2xx, status_4xx, status_5xx,
+//     by_provider: { [providerKey]: { count, cache_hit, cache_miss, cache_bypass, fallback_count } },
+//     by_owner_tier: { owner: N, guest: N, anonymous: N },
+//     by_path: { '/v1/chat/completions': N, '/v1/models': N },
+//     median_latency_ms, p95_latency_ms,
+//   }
+export function aggregateRequests({ windowMs, olpHome }): RequestAggregate;
+
+// Top-N fallback chains by trigger count in window. Returns sorted array:
+//   [{ chain: ['anthropic', 'openai'], count: 42, first_seen, last_seen }, ...]
+export function topFallbackChains({ windowMs, limit, olpHome }): FallbackChainSummary[];
+
+// Daily series of request_count + latency_median over N days. Returns sorted array:
+//   [{ date: '2026-05-22', request_count, median_latency_ms, by_provider }, ...]
+export function spendTrendDaily({ days, olpHome }): DailySpendEntry[];
+
+// Cache hit rate snapshot (in-memory cacheStore stats + audit-derived numerator).
+// Differs from /cache/stats: that returns the live in-memory CacheStore stats;
+// this is the audit-side derived rate over the window.
+export function cacheHitRateWindow({ windowMs, olpHome }): CacheHitRateSummary;
+```
+
+### 4.2 Window semantics
+
+`windowMs` is a duration ending at "now"; `[now - windowMs, now)`. The implementation walks files whose date overlaps that range: today's `audit.ndjson` always; `audit-YYYY-MM-DD.ndjson` for each prior date in range. A line is included only if its `ts` (ISO-8601) falls in the window.
+
+For the 30-day spend trend, `windowMs = 30 * 86400 * 1000`. The implementation buckets per UTC day and returns one entry per day, including days with zero requests (sparse-fill).
+
+### 4.3 PII discipline
+
+Per ADR 0007 § 8, audit events contain no message content, no response content, no raw tokens. The query layer relays only the schema fields. It MUST NOT introduce derived fields that reveal content (e.g., "first 50 chars of prompt").
+
+### 4.4 Error handling
+
+- Missing file → empty iteration (not an error).
+- Malformed JSON line → log warn `audit_query_skip_malformed` + skip; continue.
+- File-read error (EACCES, etc.) → throw to caller; the dashboard endpoint surfaces 500 with diagnostic message.
+
+---
+
+## 5. Audit rotation
+
+### 5.1 Trigger
+
+Rotation fires on the **first append after a UTC date change**. Implementation lives in `lib/audit.mjs` (extended at D49). On each `appendAuditEvent` call:
+
+1. Compute `today = new Date().toISOString().slice(0, 10)` (e.g., `'2026-05-25'`).
+2. Read a module-scoped `_currentDate` cached at startup.
+3. If `today !== _currentDate` AND `audit.ndjson` exists AND it is non-empty:
+   - Rename `audit.ndjson` → `audit-${_currentDate}.ndjson` (the previous day's date).
+   - Set `_currentDate = today`.
+   - Continue with the append (new `audit.ndjson` opens via append-create).
+
+The check is per-call (microsecond cost). The rename is the only filesystem heavy op and fires once per UTC day.
+
+### 5.2 External-cron alternative (`bin/olp-audit-rotate.mjs`)
+
+An auxiliary script is shipped at D52 for operators who prefer cron-driven rotation (e.g., to rotate exactly at 00:00:00 UTC rather than "first request after midnight"). The script does the same rename + state-bump logic but can be invoked from a host cron / launchd job. The in-server check remains as a safety net; both can coexist.
+
+### 5.3 Concurrent-rotation safety
+
+In-process: the rotation logic is wrapped in a per-process lock (`Map<key='audit-rotate', Promise>`) so two concurrent `appendAuditEvent` calls don't both attempt the rename. External cron + in-server check: the in-server check sees the rename has already happened (file with today's date already exists if cron beat it); the no-op fallback is "if `audit.ndjson` exists, append; else create + append" — POSIX semantics.
+
+### 5.4 Renamed-file query path
+
+The query layer (§ 4) walks `audit-${date}.ndjson` files for any date in the window. Today's file is always `audit.ndjson` (not renamed yet); yesterday + prior are date-suffixed.
+
+---
+
+## 6. Dashboard panels (per spec § 4.6, Lane 5 = B full)
+
+`dashboard.html` is a single static file served from `/dashboard`. Renders 4 panels in a 2×2 grid:
+
+### 6.1 Panel 1 — Per-provider quota / credit pool
+
+For each loaded provider, calls `provider.quotaStatus()` (ADR 0002 Provider contract). Returns whatever the provider can report (e.g., Anthropic Plan limits remaining, Codex credit pool balance) OR `null` (provider opts out — Phase 2 mistral has no quota API).
+
+Each row shows:
+- Provider key + display name
+- Quota remaining / quota total (or "n/a" if null)
+- Last poll timestamp
+
+### 6.2 Panel 2 — Per-provider request count + cache hit rate + fallback rate (last 24h)
+
+Uses `aggregateRequests({ windowMs: 86400 * 1000 })`. One row per provider showing:
+- Request count (total served by that provider, regardless of chain position)
+- Cache hit rate (% of requests where `cache_status === 'hit'`)
+- Fallback rate (% of requests where `fallback_hops > 0`)
+- 5xx error rate (% of requests where `status_code >= 500`)
+
+### 6.3 Panel 3 — Multi-provider unified spend trend (last 30 days)
+
+Uses `spendTrendDaily({ days: 30 })`. Shows a sparkline-style chart (vanilla SVG, no library) with:
+- X axis: 30 daily buckets
+- Y axis: request count per day (stacked by provider color)
+- Hover tooltip: per-day breakdown by provider
+
+Note: "spend trend" is the spec's term — at v0.3.0 we don't have provider-side cost integration (Anthropic Plan is flat-rate per Anthropic 2026-06-15 split per the learning memory). So "spend" is proxied by request count. A future ADR may add cost weights per provider when commercial cost-tracking lands.
+
+### 6.4 Panel 4 — Top fallback chains by trigger count
+
+Uses `topFallbackChains({ windowMs: 86400 * 1000, limit: 10 })`. Lists top 10 chains:
+- Chain shape (e.g., `anthropic → openai`)
+- Trigger count
+- First / last seen timestamps
+
+### 6.5 Refresh model (Lane 4 = A)
+
+The dashboard sets a 30s `setInterval` that calls `fetch('/v0/management/dashboard-data')` + updates DOM in place (no full reload). Initial fetch on page load. The interval pauses when the page is hidden (via `document.visibilityState` listener) to avoid useless background polls.
+
+### 6.6 Localhost-bound by default
+
+The dashboard is served from the existing OLP HTTP port (default 4567 since v0.4.0 / D60; 3456 pre-v0.4.0) which is already bound to `127.0.0.1` per `server.mjs` startup (`server.listen(PORT, '127.0.0.1', ...)`). No additional binding logic. Remote operators access via SSH tunnel; ADR 0007 § 7 owner-only auth provides the per-request gate.
+
+---
+
+## 7. Server endpoints (D50)
+
+All endpoints are owner-only per ADR 0007 § 7 (owner-tier validation through `authenticate`). Non-owner identities get 401 / 403 per existing patterns; anonymous (when `allow_anonymous: true`) gets 401 (these are management endpoints, not user-facing).
+
+### 7.1 `GET /dashboard`
+
+Serves `dashboard.html`. Owner-only gated. Content-Type `text/html; charset=utf-8`. Static file read once at server startup + cached in memory (small, no need to re-read per request).
+
+### 7.2 `GET /v0/management/dashboard-data`
+
+Returns the JSON payload the dashboard's 30s poll consumes. Shape:
+
+```json
+{
+  "generated_at": "<ISO-8601>",
+  "window_24h": <RequestAggregate from §4.1>,
+  "quota": [
+    { "provider": "anthropic", "quota_remaining": 1234, "quota_total": 5000, "polled_at": "<ISO-8601>" },
+    { "provider": "openai", "quota_remaining": null }
+  ],
+  "spend_trend_30d": <DailySpendEntry[] from §4.1>,
+  "top_fallback_chains_24h": <FallbackChainSummary[] from §4.1>,
+  "cache_stats": <stats from server.mjs cacheStore.stats() — global aggregate>
+}
+```
+
+### 7.3 `GET /v0/management/quota`
+
+Returns just the quota array (subset of dashboard-data; useful for scripted monitoring).
+
+### 7.4 `GET /cache/stats`
+
+Returns the live in-memory `cacheStore.stats()` shape. Planning authority is **OLP v0.1 spec § 4.6** (which names `/cache/stats` explicitly); ADR 0005's `Consequences/Mitigations` paragraph (~ line 279) references it as the monitoring surface for per-`(provider, model)` cache hit-rate breakdown.
+
+**Shape gap to resolve at D50.** The current `cacheStore.stats()` in `lib/cache/store.mjs:320-350` returns `{ hits, misses, size, inflightCount }` — global aggregate only, no per-`(provider, model)` breakdown. If D50 reveals the shape is insufficient for Panel 2 (per-provider 24h cache hit rate, currently sourced from `aggregateRequests` audit-side rather than `cacheStore.stats`), the dashboard endpoint is satisfied. If a future panel needs the per-`(provider, model)` breakdown that spec § 4.6 implies, D50 amends the store shape + an ADR 0005 amendment fires at that time. Phase 3 acceptance criteria do not require the breakdown.
+
+### 7.5 Audit on management endpoints
+
+All four endpoints append an audit row via the existing `appendAuditEvent` pattern. Path values are `/dashboard` / `/v0/management/dashboard-data` / `/v0/management/quota` / `/cache/stats`. The 30s poll generates 2880 dashboard rows per day per owner — manageable at family scale, but noted as a knob (a future amendment may suppress audit for these paths if they become noise-dominant).
+
+---
+
+## 8. Auth gating
+
+Reuses ADR 0007 § 7 owner-vs-non-owner model + introduces a second gating mode.
+
+**Two gating modes (this ADR formalizes the distinction):**
+
+- **`owner_only_trim`** (Phase 2 / D46 model) — non-owner identities receive a 200 response with a trimmed payload (e.g., `/health` returns `{ ok, version }` only). Used when the endpoint has a baseline payload that is safe to share with all identities and an enriched payload only for owners.
+- **`owner_only_block`** (Phase 3 / D48 new) — non-owner identities receive `401 invalid_or_revoked_key` (or `401 auth_required` if no token). Used when the entire payload is sensitive and there is no safe baseline to share (Dashboard quota stats, fallback chains by trigger, etc. all reveal operational behaviour that should not leak to non-owner identities).
+
+The four new endpoints (`/dashboard`, `/v0/management/dashboard-data`, `/v0/management/quota`, `/cache/stats`) are `owner_only_block`. `/health` remains `owner_only_trim`.
+
+The owner_only_endpoints config gains four entries; the gating-mode distinction is implementation-side (the handler decides whether to trim or block based on the endpoint). Server startup defaults `owner_only_endpoints` to include `/health` + the four new ones (Phase 3 default; operator can opt-out per-endpoint via config). Pre-Phase-3 deployments with `owner_only_endpoints: ['/health']` continue to work — the new endpoints will 401 for non-owner under that legacy config because the handler is `owner_only_block`-mode regardless of the config list (the config controls /health's trim/full toggle only; the management endpoints are not opt-out-able to a non-401 response).
+
+`401` shapes match Phase 2 / D45 pattern: JSON `{ error: { message, type } }` with `type: 'auth_required'` or `'invalid_or_revoked_key'`.
+
+---
+
+## 9. Failure modes + graceful degradation
+
+| Failure | Behavior |
+|---|---|
+| `audit.ndjson` absent (fresh install) | Empty arrays in all aggregates; dashboard shows "No requests in window" panels |
+| `audit-YYYY-MM-DD.ndjson` corrupted (one bad line) | Skip line + log warn; continue; dashboard rendering unaffected |
+| Provider `quotaStatus()` throws | Panel shows that row as `quota: "error"`; other providers' rows render normally |
+| Dashboard `/v0/management/dashboard-data` query >5s | Dashboard JS shows "Loading…" with a timeout; second poll attempts after 30s |
+| `audit.ndjson` rotation fails (rename EACCES) | `appendAuditEvent` warn `audit_rotate_failed` + continues appending to the un-rotated file; next call retries the rotation |
+| File handle limit hit during 30-day query (many files open) | Query reads one file at a time (no parallel reads); never opens >2 simultaneously |
+
+The dashboard degrades visibly (per-panel error states) rather than failing whole-page.
+
+---
+
+## 10. Acceptance criteria
+
+Implementation D-days (D49+) MUST land tests covering:
+
+1. **`readAuditWindow`** correctly iterates events from today's `audit.ndjson` + N prior rotated files within the window.
+2. **`readAuditWindow`** skips malformed lines without throwing; logs warn for each.
+3. **`aggregateRequests`** correctly counts by provider + cache_status + owner_tier + path; correctly computes median + p95 latency.
+4. **`topFallbackChains`** returns sorted by count descending; ties broken by first-seen timestamp ascending.
+5. **`spendTrendDaily`** sparse-fills zero-request days; window respects UTC day boundaries.
+6. **Daily rotation** — writing past UTC midnight renames `audit.ndjson` → `audit-<yesterday>.ndjson` and continues appending to a fresh `audit.ndjson`.
+7. **Cross-file query** — a 30-day window with mixed rotated files returns correctly merged results.
+8. **Concurrent rotation safety** — N concurrent `appendAuditEvent` calls during a UTC date change result in exactly one rename + all lines append to the correct file.
+9. **`GET /dashboard`** returns 200 HTML to owner; 401 to non-owner. This includes the case where `allow_anonymous: true` AND no Authorization header is presented: the authenticate middleware produces an anonymous identity, the `owner_only_block` mode then rejects with 401 (per § 8 — anonymous is non-owner; management endpoints block, do not trim). When `allow_anonymous: false` + no header, 401 fires earlier at the authenticate middleware itself. Test must cover both cases.
+10. **`GET /v0/management/dashboard-data`** returns 200 JSON to owner with all required fields populated.
+11. **`GET /cache/stats`** returns 200 JSON to owner with the live in-memory cache stats shape.
+12. **Dashboard HTML smoke** — fetched via test http client + parsed → has the 4 panel containers + 30s poll script; no JS console errors when loaded in a real browser (manual or playwright; manual is acceptable at Phase 3).
+13. **Audit on management endpoints** — calling `/v0/management/dashboard-data` appends an audit row with `path: '/v0/management/dashboard-data'` and `status_code: 200`.
+14. **Graceful degradation** — when a provider's `quotaStatus()` throws, the dashboard endpoint still returns 200 with that provider's quota row showing `"quota_remaining": null` and an error indicator.
+15. **PII guard** — every aggregate query function asserts at the test level that returned data does NOT include any message content; the `prompt`/`messages`/`response`/`content` fields MUST NEVER appear in any output shape.
+
+---
+
+## 11. Forward path (Phase 4+)
+
+Items deliberately deferred:
+
+- **SQLite migration (Option 3 hybrid)** — trigger: query latency >2s on a typical owner session, OR Dashboard usage scales beyond family (>5 owners polling). Preconditions per ADR 0007 § 13: engines bump + CI matrix change as a separate prior PR.
+- **SSE push for dashboard live updates** — trigger: 30s poll feels stale, OR operator wants real-time view of streaming requests. Reuses existing streaming infra from ADR 0005 Amendment 8 (v1.x streaming SF when it ships).
+- **Key-mgmt UI from dashboard** — owner can create/revoke/edit keys from the web UI rather than CLI. Out of Phase 3 because (a) it adds a write surface to the dashboard requiring careful CSRF handling, (b) security review of the auth flow is non-trivial, (c) the CLI surface from D47 covers the same use cases.
+- **Cost weights per provider** — once provider-side cost tracking is feasible, "spend trend" can show actual dollars. At v0.3.0 it's a request-count proxy.
+- **Audit retention / max-days policy** — currently unbounded; operator manages disk. A Phase 3+ amendment adds `audit_max_days` config when an operational need emerges.
+- **Per-key dashboard views** — owner sees aggregate; per-key drill-down is a future amendment.
+
+---
+
+## 12. Out of scope (explicitly NOT in Phase 3)
+
+- Per-key per-provider auth artifact mapping (ADR 0007 § 12; Phase 4+).
+- `tried_providers` schema semantics fix on `key_no_provider_access` 403 — D45 reviewer P2 deferral. Tracked as a Phase 3 implementation D-day (D53) but NOT part of ADR 0008; documented in ADR 0004 amendment or ADR 0007 § 8 amendment at D53.
+- All ADR 0007 § 12 deferrals other than Dashboard + audit query layer + rotation.
+- Externally-visible Dashboard (anything bound to 0.0.0.0 / public). Operator SSH-tunnels.
+
+---
+
+## 13. Phase 3 sprint shape
+
+| D-day | Deliverable | Type |
+|---|---|---|
+| **D48** | This ADR (0008 draft) | ADR-only |
+| **D49** | `lib/audit-query.mjs` + Suite 23 unit tests | impl |
+| **D50** | `server.mjs` `/v0/management/*` endpoints + `/dashboard` route + Suite 24 HTTP tests | impl |
+| **D51** | `dashboard.html` + render JS + 30s poll | impl |
+| **D52** | Audit daily rotation (`lib/audit.mjs` extension + `bin/olp-audit-rotate.mjs` + Suite 25 rotation tests) | impl |
+| **D53** | `tried_providers` schema fix (D45 P2 deferral; small) | impl |
+| **D54** | E2E browser smoke (manual or playwright) + AGENTS / README polish | tests + docs |
+| **D55** | Phase 3 close → v0.3.0 (release-kit PR per `phase_close_trigger`) | release |
+
+Each D-day = implementor + fresh-context opus reviewer per Iron Rule 10. Estimated wall-clock: similar to Phase 2 cadence (1 intense session per D-day under standing autopilot).
+
+---
+
+## Consequences
+
+**Positive:**
+
+- Operators get an at-a-glance view of OLP's behaviour (was a tail/grep exercise pre-Phase-3).
+- Audit layer becomes queryable, not just append-only; `lib/audit-query.mjs` is reusable for future CLI tools (`olp-audit search` etc.).
+- Daily rotation bounds per-file size + creates a natural archival unit.
+- Owner-only gating reuses Phase 2 auth model (no new auth surface).
+- v0.1 spec § 4.6 Dashboard requirements are met without introducing a build step / database / framework.
+
+**Negative / trade-offs:**
+
+- In-memory ndjson scan is O(N) per query; if audit grows to millions of lines (single-host years), the 30-day query becomes slow. Mitigation: ADR 0007 § 13 Option 3 hybrid is the documented next step; trigger is observed slowness.
+- 30s poll generates baseline traffic when dashboard is open (2880 management requests/day per owner). Not a real cost but worth observing.
+- Audit rotation is "first append after UTC midnight" which means a server with zero requests overnight rotates lazily (first request of the new day triggers it). External cron at D52 covers the strict-midnight case.
+- No automatic audit retention. A multi-year-running server accumulates files; operator manages.
+
+**Reversibility:**
+
+- Dashboard is a static file + 4 endpoints. Removable in a future revert PR if Phase 3 retrospectively proves unwanted.
+- Audit rotation is additive — disabling reverts to single-file behaviour without code change (operator never invokes the cron + the in-server rotation can be guarded by a config flag).
+- The `lib/audit-query.mjs` module is consumed by Dashboard endpoints + can be used standalone; removing it requires unrelated endpoint surgery.

+
+## 1. Context
+
+### 1.1 The triggering external work
+
+OCP shipped ADR 0007 (`docs/adr/0007-interactive-mode-pool.md` in `dtzp555-max/ocp`) on 2026-05-25, draft status. The ADR designs a dual-path execution model for the post-2026-06-15 Anthropic billing split:
+
+- **Current `claude -p` path**: programmatic billing → Agent SDK $100/month credit pool (~20–50 heavy coding sessions/month).
+- **Proposed interactive-mode path**: spawn Claude without `-p`, communicate via either (Transport A) piped NDJSON over stdio or (Transport B) `node-pty` PTY — possibly classified as interactive billing → subscription pool.
+
+The OCP team accepted the *concept* but rejected an external contributor's PR #101 implementation (tmux + hook-file polling + `--dangerously-skip-permissions`) on alignment + security grounds, then drafted ADR 0007 as the clean redesign.
+
+### 1.2 Why this is OLP's concern
+
+OLP's founding premise (ADR 0001) was that OCP would become uneconomical post-2026-06-15, motivating a multi-provider hedge. OLP's `lib/providers/anthropic.mjs` today uses the same `claude -p` invocation OCP uses → same billing consequence post-2026-06-15.
+
+If OCP's ADR 0007 P0 experiment confirms that an interactive-mode spawn (Transport A or B) bills against subscription rather than Agent SDK credit, the implementation pattern is directly portable to OLP's anthropic provider plugin. OLP would inherit the same billing benefit without needing to commission an independent P0.
+
+If P0 fails for both transports, OLP's anthropic provider remains stuck on `-p` post-June-15; the multi-provider routing (OpenAI Codex, Mistral) becomes the operational mitigation, exactly per OLP's original founding logic.
+
+### 1.3 The unverified premise (binding caveat)
+
+Per OCP ADR 0007 § "Unverified Premise":
+
+> "TTY detection matters. Local testing (Claude Code 2.1.150) shows: in a real TTY, `claude` without `-p` enters the TUI and does not emit NDJSON. With piped stdin/stdout (`child_process.spawn`), it emits NDJSON even without `-p`. This means Anthropic could use `isTTY` as the billing signal, not the `-p` flag."
+
+OLP cannot independently confirm or refute this prior to 2026-06-15 — Anthropic's billing pool signaling is not exposed on any observable surface until the billing split goes live. **Any OLP implementation that bets on Transport A (stdio pipe) without P0 confirmation risks burning real Agent SDK credit on every Anthropic request.**
+
+---
+
+## 2. Decision
+
+**Option 3 — Wait for OCP ADR 0007 P0 experiment outcome, then port the validated approach.**
+
+Rationale:
+
+- **Avoid duplicated P0 risk.** Both OCP and OLP would run the same experiment against the same Anthropic billing pool. OCP is already designed to run it; OLP riding their result is a free observation.
+- **Lower decision-tree noise.** P0 has three outcomes (Transport A wins / Transport B wins / both fail). OLP's right answer differs per outcome; making the decision before the data is speculation.
+- **No code is wasted.** OLP currently routes anthropic via `claude -p`, which works (just expensive post-June-15). The cost during the wait window is bounded by the Agent SDK $100/month credit + OLP's family-scale request volume.
+
+What "wait" means concretely:
+
+1. **No code change to `lib/providers/anthropic.mjs`** until OCP ADR 0007 transitions from Draft → Accepted (which requires P0 success per OCP ADR 0007 § "Status").
+2. **No Phase 4 D-day scheduled for this scope** until that transition AND maintainer issues an explicit Phase 4 "go" naming this ADR.
+3. **This placeholder ADR stays Draft** until either OCP P0 lands AND OLP decides to port, OR OCP P0 fails decisively AND OLP marks this ADR Rejected with a "shelved per upstream P0 failure" note.
+
+---
+
+## 3. P0 outcome → OLP action decision tree
+
+Recorded here so a future Phase 4 brief can act mechanically once OCP P0 lands.
+
+```
+OCP ADR 0007 P0 result
+  │
+  ├─ Transport A (stdio pipe) confirmed interactive-billing
+  │   → OLP Option 1 OR Option 2 (see § 4); maintainer decides.
+  │     Likely Option 1: port the lib/interactive-pool.mjs +
+  │     billing-router.mjs pattern into lib/providers/anthropic.mjs.
+  │     Updates ADR 0006 to spell out the new spawn mode.
+  │
+  ├─ Transport B (PTY) confirmed; Transport A fails
+  │   → OLP Option 1 with PTY adapter; node-pty dependency added
+  │     under engines-bump scrutiny (this triggers a separate prior
+  │     PR per ADR 0007 § 11-like discipline: native addon adds
+  │     CI matrix work).
+  │
+  ├─ Both transports billed as programmatic
+  │   → OLP marks this ADR Rejected. Anthropic provider stays on
+  │     `claude -p`. Operational mitigation: family-scale users
+  │     either (a) accept the Agent SDK $100 cap, (b) bring their
+  │     own API key (BYOK env path is already there), or (c) shift
+  │     volume to other providers (Codex / Mistral) via OLP's
+  │     existing fallback chain.
+  │
+  └─ P0 results unobservable (billing signals not exposed)
+      → Continue waiting. Re-evaluate one billing cycle (30 days)
+        post-2026-06-15. OLP Anthropic provider remains on `-p`
+        path during the wait; users see Agent SDK credit consumption
+        as the cost signal.
+```
+
+---
+
+## 4. Implementation lanes (to be selected when P0 lands)
+
+This section is informational only. No lane is selected at placeholder time.
+
+### Option 1 — OLP parallel implementation
+
+OLP's `lib/providers/anthropic.mjs` reimplements OCP's interactive pool natively. Replaces the current `claude -p` spawn with a pool-managed warm process + adapter selected per P0 outcome.
+
+- **Pros:** OLP self-contained; no runtime dependency on OCP being installed.
+- **Cons:** Duplicates substantial logic (pool lifecycle, transport adapter, crash backoff DEGRADED, permission auto-response). Two codebases drift over time.
+
+### Option 2 — OLP chains OCP as backend
+
+OLP's `lib/providers/anthropic.mjs` invokes OCP (via its existing HTTP entry surface, or via a future direct-spawn API) rather than spawning `claude` directly. OLP becomes a multi-provider layer ON TOP OF OCP for the Anthropic provider; other providers (Codex, Mistral) continue to be direct.
+
+- **Pros:** Zero duplication; OLP benefits from OCP's P0-validated work automatically. Architectural separation: OCP owns Claude execution, OLP owns multi-provider routing.
+- **Cons:** OLP gains a runtime dependency on OCP being installed + running. Double caching (OCP cache + OLP cache; cache key composition needs to avoid stampede). OCP's HTTP shim is OpenAI-spec-compatible but adds an extra hop's latency. OCP failure modes propagate.
+
+### Option 3 — Both (default to OCP backend if available, fallback to local pool)
+
+A hybrid: OLP detects OCP installed locally, prefers chaining; otherwise falls back to the parallel implementation. Most defensive but most complex.
+
+**Default at placeholder time:** Option 1 is the simpler ship if P0 transports prove out. Option 2 is the cleaner architecture but adds operational coupling. Maintainer decides at P0-resolution time.
+
+---
+
+## 5. Risk assessment (placeholder snapshot)
+
+| Risk | Likelihood (now) | Impact | Mitigation pending P0 |
+|---|---|---|---|
+| OLP forgets this ADR exists | Medium (multi-month wait) | High (would mean OLP misses the post-June-15 window) | This ADR + cc-rules memory `~/.cc-rules/memory/learnings/ocp_adr_0007_interactive_mode_pool.md` |
+| OCP ADR 0007 P0 fails entirely | Medium | High for OLP Anthropic users (Agent SDK $100 cap binds) | OLP's multi-provider fallback (Codex/Mistral) already shipped as Phase 1 work; users have a path |
+| OCP ADR 0007 ships incomplete (interim) | Medium | Medium (OLP can't reliably port) | Wait for OCP to mark Accepted; don't port from Draft |
+| Anthropic policy changes mid-wait | Medium | Depends — could obsolete the whole approach | Re-read OCP ADR 0007 + this ADR before any Phase 4 anthropic work; no decisions on stale information |
+
+---
+
+## 6. Out of scope (explicitly NOT in this ADR)
+
+- **Any code change.** This is a placeholder + decision-tree record only.
+- **OCP P0 design.** That work is OCP's responsibility per OCP ADR 0007 § "Implementation phases".
+- **A new OCP-OLP integration protocol.** If Option 2 is selected at P0-resolution time, the integration shape is a separate ADR.
+- **Engines-bump for node-pty.** Only relevant if P0 picks Transport B and Option 1 is selected. Then it lands as a separate prior PR per the ADR 0007 § 11 pattern.
+
+---
+
+## 7. Phase 4 priority interaction
+
+This ADR is recorded BEFORE Phase 4 implementation scope is finalized. Phase 4 currently lists (per OLP v0.3.0 CHANGELOG):
+
+- Per-key per-provider auth artifact mapping (ADR 0007 § 12 deferral)
+- Audit retention policies (ADR 0008 § 11 deferral)
+- SQLite hybrid migration (ADR 0007 § 13 trigger)
+- Provider-cost weights for spend trend (ADR 0008 § 11 deferral)
+
+If OCP P0 succeeds, **the interactive-mode port likely jumps to the top of Phase 4** (highest user impact: keeps OLP Anthropic users on subscription billing). The other items remain Phase 4 but reorder downstream.
+
+If OCP P0 fails, **this ADR is shelved** and Phase 4 ordering is unchanged.
+
+---
+
+## Consequences
+
+**Positive:**
+
+- OLP retains a documented anchor for the interactive-mode option without committing implementation effort prematurely.
+- Future Phase 4 planning has a structured decision tree, not a vague "we should look at OCP someday".
+- Cross-machine + cross-session memory (cc-rules) ensures the dependency is visible to any future session reading the OLP project context.
+
+**Negative:**
+
+- During the wait window (now → P0 outcome ≥ 2026-07-15), OLP Anthropic users consume Agent SDK credit post-2026-06-15. Bounded by family-scale request volume but a real operational cost.
+- Some risk that "wait" turns into "forget" if multiple unrelated Phase 4 priorities crowd the agenda. Mitigated by this ADR + the cc-rules memory pointer.
+
+**Reversibility:**
+
+- This is a placeholder. Either P0 result transitions it (Accepted → port, Rejected → shelve) cleanly. The placeholder itself doesn't lock OLP into anything.
+
+---

+
+- **OCP ADR 0007** at `~/ocp/docs/adr/0007-interactive-mode-pool.md` (maintainer workstation). Project repo: `dtzp555-max/ocp`.

+- **OLP ADR 0008** (Dashboard + Audit Query, Phase 3) — Dashboard per-provider fields must continue to populate.
+- **CLAUDE.md `release_kit.phase_rolling_mode`** — current_phase: Phase 4 (post-v0.3.0); this ADR explicitly does NOT consume a Phase 4 D-day until P0 lands.
+- **Standing autopilot grant** (`~/.cc-rules/memory/auto/standing_autopilot_phase_2.md` in cc-rules `bf0ed9a`) — Phase 4+ requires new authorization; this placeholder is a decision-tree pre-record, not Phase 4 implementation.

+## Status transitions (recorded for clarity)
+
+- 2026-05-25 — Created as Draft (Placeholder). OCP ADR 0007 also Draft.
+- _(future)_ — If OCP ADR 0007 → Accepted with a confirmed transport: this ADR moves to "Pending Phase 4 implementation D-day", maintainer decides Option 1 / 2 / 3 + lane.
+- _(future)_ — If OCP ADR 0007 → Rejected: this ADR moves to "Shelved (upstream P0 failure)" with a note explaining the fallback (multi-provider routing already covers).

+# ADR 0010 — Phase 4 Charter: Operator + Client UX
+
+**Status:** Accepted (Phase 4 open as of 2026-05-26)
+**Date:** 2026-05-26
+**D-day:** D60 (charter + default port change)
+
+---
+
+## Context
+
+Phases 1 — 3 shipped OLP's structural core: HTTP entry surface, IR, provider plugins, fallback engine, content-addressed cache (including streaming-path singleflight at D57+D58 → v0.3.2), multi-key auth + audit ndjson + daily rotation, owner-only management endpoints + dashboard. v1.x roadmap items #1 / #2 / #4 / #7 are closed. Items #3 / #5 / #6 remain trigger-gated.
+
+Two complementary brainstorm passes (2026-05-26) — a comprehensive OCP feature audit + a multi-provider proxy / IDE integration prior-art survey — converged on a clear gap: **OLP's operator and client surfaces are 0% inherited from OCP**. Today OLP has `bin/olp-keys` and `bin/olp-audit-rotate` as the entire operator CLI, no `olp doctor` / no `olp-connect`, no Telegram/Discord integration, no SSE heartbeat for long-running streams behind reverse proxies. Family members get OLP API keys via out-of-band paste, point their IDEs at OLP via the README's one-line example, and discover failure modes via curl. OCP's UX worked because of a load-bearing combination: README `paste-this-prompt-to-Claude-Code` instructions + machine-readable `ocp doctor next_action.ai_executable[]` + `ocp-connect` zero-config LAN setup + `/health.anonymousKey` self-advertising token + `/ocp` Telegram slash commands. **Phase 4 brings these forward as OLP-native primitives.**
+
+A separate strategic decision — should OLP add `/v1/messages` (Anthropic-shape entry surface) for Claude Code support — was considered and **rejected for Phase 4** (see § "Out of Phase 4 scope" below). The decision is recorded with an explicit re-open trigger.
+
+---
+
+## Decision
+
+Phase 4 scope is **Operator + Client UX**. The phase opens 2026-05-26 with D60 (this charter + default port change). Phase 4 close ships v0.4.0; per `CLAUDE.md release_kit.phase_rolling_mode`, the close PR is maintainer-triggered.
+
+### In scope — Phase 4 D-day plan (~13 D-days)
+
+| D-day | Deliverable | Authority | Estimate |
+|---|---|---|---|
+| **D60** | Default port `3456 → 4567` + this ADR 0010 charter + README / CHANGELOG / ADR 0001 + ADR 0008 amendments | This charter | 0.5d |
+| **D61 — D63** | SSE heartbeat (opt-in via `streaming.heartbeat_interval_ms` config; eager-headers-post-spawn; `X-Accel-Buffering: no` constant) + `recentErrors[20]` ring buffer + `/status` combined endpoint | Port OCP `server.mjs:660-685` + `301-358` + `1151-1188`; OCP `docs/superpowers/specs/2026-04-25-47-sse-heartbeat-design.md` | 2.5d |
+| **D64 — D67** | `olp` Node-based CLI scaffold (subcommands `status / health / usage / models / logs / cache / providers / chain show / restart / doctor`) + `olp doctor` machine-readable `next_action.ai_executable[]` framework + one fix-template per shipped provider plugin | Port OCP `ocp` bash wrapper (translated to Node — bash dep on python3 is a known fragile point) + OCP `scripts/doctor.mjs` framework | 4d |
+| **D68 — D70** | `olp-connect <ip>` client-side IDE auto-config (Cline / Continue.dev / Cursor / Aider / Claude Code / OpenClaw detection) + `/health.anonymousKey` field (opt-in via `auth.advertise_anonymous_key` config; default off) + ADR 0011 (anonymous-key deployment-context limits — trusted-LAN-only invariant explicit) | Port OCP `ocp-connect` + `server.mjs:1454,1488` | 3d |
+| **D71 — D73** | `olp-plugin/` (OpenClaw gateway plugin for `/olp` Telegram/Discord slash commands; subcommand parity with `olp` CLI minus mutations) + `docs/integrations/{continue.md,cline.md,cursor.md,aider.md,claude-code.md,openclaw.md}` IDE setup docs | Port OCP `ocp-plugin/index.js`; cross-ref Prior-Art § 3 + § 4 | 3d |
+| **close** | v0.4.0 release PR — `package.json` bump, CHANGELOG promotion, `release_kit.phase_rolling_mode` advance to Phase 5 pre-release identifier | `CLAUDE.md release_kit overlay` | maintainer-triggered |
+
+### Out of Phase 4 scope (with explicit triggers)
+
+#### `/v1/messages` — Anthropic-shape entry surface
+
+**Status:** Deferred. Re-enable strictly gated on ADR 0009 P0 success.
+
+**Value matrix (decisive):**
+
+| Scenario | Without `/v1/messages` | With `/v1/messages` |
+|---|---|---|
+| Maintainer's own Claude Code usage | Direct via Anthropic OAuth → subscription (today) or Agent SDK pool (post-2026-06-15) | Same — maintainer never routes own CC through OLP per stated workflow |
+| Family member wanting CC access | Not supported (OAuth is full-account; OLP CLI tokens are scoped) | CC via `ANTHROPIC_BASE_URL=http://olp:4567` + `olp_*` token |
+| **P0 succeeds** (ADR 0009 interactive-mode bills as subscription) | OpenAI-shape IDE clients (Cline/Continue/Cursor) all benefit automatically via OLP's anthropic plugin | CC users additionally benefit; both subscription-billed |
+| **P0 fails** (interactive-mode bills as Agent SDK same as `-p`) | OpenAI-shape clients still work; no billing change | CC users get same billing as direct OAuth; **fallback to codex/mistral degrades Anthropic-specific features (tool_use schema mismatch / cache_control drop / computer_use no-op / thinking-block drop)** more severely than OpenAI-shape clients which speak the multi-provider lingua franca |
+
+**Rationale.** Under P0 failure, `/v1/messages` provides no billing benefit AND degrades worse on fallback than OpenAI-shape clients (because OpenAI tool schema is the cross-provider standard). The security benefit (no OAuth exposure) is equally achievable via Cline/Continue/Cursor. **Net non-positive under P0 failure.**
+
+**Re-open condition.** (a) ADR 0009 P0 confirms interactive-mode billing classification as subscription (≥ 2026-07-15) AND (b) maintainer explicitly opens Phase 5 "Anthropic-shape hub" scope with the name of at least one family member who wants CC access. If only (a) fires without (b), `/v1/messages` is reconsidered at the start of whichever phase covers it but is not auto-opened.
+
+**README posture (Phase 4).** README § Supported Clients explicitly lists OpenAI-compatible clients (Cline, Continue.dev, Cursor, Aider, OpenClaw bots). Claude Code is listed as **Not supported as an OLP client**, with the explicit alternative "Cline + OLP" (same fallback chain available, better cross-provider compatibility). README links to this ADR for the reasoning.
+
+#### Other deferred items
+
+- **v1.x roadmap #3 (soft trigger reactivation)**, **#5 (provider `cacheKeyFields` mask)**, **#6 (streaming SPAWN_FAILED salvage)** — trigger conditions per `docs/v1x-roadmap.md` have not fired. Not in Phase 4.
+- **Anthropic / codex billing audits** — date-gated (`anthropic.mjs:53, 416, 441` say 2026-06-16; `codex.mjs:572` post-D7 E2E audit). Not in Phase 4.
+- **`context_window_exceeded` fallback trigger** (LiteLLM prior-art) — small ADR amendment + trigger taxonomy add; opportunistically in Phase 5 unless trigger fires sooner.
+- **`X-OLP-Cost-USD` per-request response header** — depends on provider-cost weights table (Phase 5 prerequisite).
+- **per-(provider, model) live stats Map** (replacing audit-query scan for dashboard 30s poll) — current scan latency adequate; Phase 5+.
+- **OpenTelemetry GenAI span emission** — `npm` dep + ~150 LOC; family-scale ROI marginal. Phase 6+ unless Langfuse self-host requested.
+- **Intent-based routing**, **stackable transformer plugin model** — explicit non-goals per Prior-Art § 8 anti-patterns.
+
+### Opportunistic Phase 4 micro-additions (not blocking)
+
+Items small enough to land alongside a planned D-day without scope creep, if encountered:
+
+- Env-var deny-list before provider plugin `spawn` (per OCP `server.mjs:531-534`; each plugin declares its own list)
+- 5 MB request body cap with HTTP 413 (per OCP `server.mjs:1270,1278-1281`)
+- Error-response path-sanitization (per OCP `server.mjs:1395`)
+- Stable node-path resolution in launchd plist (Homebrew `/Cellar/<ver>/` → `/opt/` rewrite; per OCP `setup.mjs:344-351`)
+- Legacy model alias resolution in `models-registry.json` (`aliases:` field; per OCP `legacyAliases`)
+
+### Exit gate — v0.4.0 close criteria
+
+1. D60 — D73 all merged with fresh-context opus reviewer APPROVE per Iron Rule 10.
+2. CI green on every D-day merge commit and on the v0.4.0 release commit head.
+3. README § Operator CLI + § IDE Setup + § Telegram/Discord Usage sections present.
+4. ADR 0010 (this charter) + ADR 0011 (anonymous-key deployment-context limits) on disk.
+5. `CHANGELOG.md "Unreleased"` promoted to `"## v0.4.0 — <date>"` with D60 — D73 entries.
+6. `package.json` bumped to `0.4.0`.
+7. `CLAUDE.md release_kit.phase_rolling_mode.current_phase` advances `Phase 4 → Phase 5`; `current_pre_release_identifier` advances `0.4.0-phase4 → 0.5.0-phase5`.
+8. Standing autopilot grant covers D-day-by-D-day execution; v0.4.0 close PR is maintainer-triggered.
+
+---
+
+## Default port change (D60 specific)
+
+The default `OLP_PORT` value moves `3456 → 4567` at this D-day. Rationale:
+
+- OCP defaults to 3456 and the maintainer's existing OCP installs stay on 3456 indefinitely.
+- A standard `olp` install on the same host without overriding `OLP_PORT` collides at bind time.
+- Setting `OLP_PORT=4567` as the default makes co-host the recommended steady state during the migration window (and beyond — there is no enforced deprecation of OCP).
+- Existing OLP deployments wanting the pre-D60 default can set `OLP_PORT=3456` in the launchd plist / shell env.
+
+**Tested invariants preserved by the port change:**
+
+- All `test-features.mjs` suites use `port: 0` (ephemeral assigned port) — no test depends on the default value. Verified via `grep -nE '\\b3456\\b' test-features.mjs` returning empty.
+- All cache / fallback / provider plugin code is port-agnostic.
+- Dashboard 30s poll uses relative paths — no port change required in `dashboard.html`.
+- `/v0/management/*` endpoints use relative paths — no client-side update required.
+
+**Files amended at D60:**
+
+- `server.mjs:17` — env-var doc comment
+- `server.mjs:74` — default value
+- `README.md` quick start + Environment Variables table + Migration from OCP § note
+- `docs/adr/0001-project-founding.md` § "Decision" paragraph about port conflict (struck and amended)
+- `docs/adr/0008-dashboard-and-audit-query.md` § 6.6 port reference
+- `CHANGELOG.md` Unreleased entry
+- This ADR
+
+---
+
+## Consequences
+
+**Positive.**
+
+- Family member onboarding goes from "maintainer texts API key + edits IDE config" to `curl -fsSL .../olp-connect | bash -s -- <ip>`.
+- `paste-this-prompt-to-Claude-Code` self-installation pattern unlocks AI-driven setup / upgrade / repair, eliminating the maintainer's Tier-1 support role.
+- Long-reasoning streams behind nginx / Cloudflare / Tailscale Funnel no longer 502 at 60s idle.
+- `/olp` Telegram slash commands enable "is OLP up?" / "show usage" / "rotate key" from anywhere with chat access.
+- OCP and OLP co-host on the same workstation, lowering the maintainer's cost of running both.
+
+**Negative.**
+
+- Phase 4 is the first phase whose scope is primarily about *operator experience* rather than functional capability. The work doesn't unlock new requests OLP can serve; it makes OLP's existing capability survive contact with real users.
+- The `olp-connect` IDE auto-detect logic accumulates IDE-specific quirks (Cline base-URL UI regressions per their issue #7128; Cursor's malformed-request-when-OpenRouter behavior; etc.). Maintenance burden grows.
+- README size grows substantially with Operator CLI + IDE Setup + Telegram/Discord sections. Discoverability of the existing technical reference (ADRs, environment variables) may degrade unless the navigation is refactored.
+
+**Neutral.**
+
+- Phase 4 deliberately spends 0 D-days on `/v1/messages`. If ADR 0009 P0 succeeds in Q3 2026, Phase 5 "Anthropic-shape hub" becomes the natural next phase, with the prerequisite IR work that Phase 4 surfaces (every IDE doc page is a test of which IR fields actually flow through). If P0 fails, `/v1/messages` shelves indefinitely and the README simply documents CC as out-of-scope.
+
+---
+
+## Alternatives considered
+
+1. **Phase 4 = `/v1/messages` first, operator UX later.** Rejected. The brainstorm matrix demonstrated `/v1/messages` is value-positive only if ADR 0009 P0 succeeds, and operator UX gains accrue regardless. Building speculative infrastructure ahead of P0 risks 5-7 D-days of work shelving.
+2. **Phase 4 = operator + client UX + `/v1/messages` together (full kitchen sink).** Rejected. ~20 D-days lengthens the Phase 4 close window unnecessarily; the natural review chunks blur; maintainer review fatigue is real.
+3. **Phase 4 = just D60 + opportunistic SSE heartbeat, no CLI / no plugin / no docs bundle.** Rejected. Each of the operator-UX items individually has small ROI; the value compounds when they ship together (CLI surfaces data → `/status` exposes shape → Telegram plugin renders → IDE docs reference → `olp-connect` automates). Splitting them across phases loses the compounding.
+4. **Defer Phase 4 entirely; jump to Phase 5 Anthropic-shape hub when P0 lands.** Rejected. Operator UX is needed now (this session is itself evidence — the maintainer spent ~30 minutes confirming OCP feature inheritance because there's no `olp doctor` answer). Waiting for P0 stalls progress on independently-valuable work.
+
+---
+
+## Authority
+
+- `docs/v1x-roadmap.md` — Phase 4 was named as the canonical destination for the post-cleanup batch since v0.3.0 close.
+- `CLAUDE.md release_kit.phase_rolling_mode` — `current_phase: Phase 4` already; this charter formalizes the contents.
+- OCP comprehensive feature audit (2026-05-26 subagent output, summarized in `~/.cc-rules/memory/auto/MEMORY.md` and in this session's transcript).
+- Multi-provider proxy / IDE integration prior-art survey (2026-05-26 subagent output).
+- ADR 0009 (Anthropic interactive-mode path placeholder) — establishes the gate for `/v1/messages` re-consideration.
+- ADR 0001 (project founding) — § "Decision" paragraph about port conflict, amended at this D-day.
+- ADR 0008 (dashboard + audit query) — § 6.6 default-port reference, amended at this D-day.
+- `~/.cc-rules/memory/auto/standing_autopilot_phase_2.md` — standing autopilot grant covering D-day-by-D-day execution; v0.4.0 close PR is maintainer-triggered per `release_kit.phase_close_trigger`.
+
+---
+
+## Procedural mechanism
+
+CC 开发铁律 v1.6 § 5.5 (release-kit overlay drives Phase boundaries) + § 10 (independent reviewer on every implementation D-day) + § 11 (minimum reviewable unit per PR — this charter ships as D60 PR alongside the default port change because both are governance-class and small).

+# ADR 0011 — Anonymous-Key Deployment-Context Limits (Trusted-LAN Invariant)
+
+**Status:** Accepted (2026-05-26)
+**Date:** 2026-05-26
+**D-day:** D70 (lands alongside D68 `olp-connect` + D69 `/health.anonymousKey`)
+
+---
+
+## Context
+
+ADR 0010 § Phase 4 D68-D70 charter scoped a three-deliverable bundle:
+
+- **D68** `olp-connect <ip>` — client-side bash script that auto-configures a
+  family member's machine to point at a remote OLP instance, including IDE
+  detection (Cline / Continue.dev / Cursor / Aider / OpenClaw) and rc-file +
+  system-level env var writes.
+- **D69** `/health.anonymousKey` field — opt-in (`auth.advertise_anonymous_key:
+  true` in `~/.olp/config.json`; default `false`) surface that emits the
+  plaintext of a designated guest-tier key so `olp-connect` can pick it up
+  with zero-config (no out-of-band token paste).
+- **D70** this ADR — codifies the deployment-context limits that make D69
+  safe.
+
+The D69 mechanism is a deliberate port of OCP's clever `PROXY_ANONYMOUS_KEY` +
+`/health.anonymousKey` pattern (OCP `server.mjs:148, 1454, 1488, 1555`,
+shipped 2026-04 under OCP issue #12 § 14 Path A) which made family-member
+onboarding go from "maintainer texts API key + edits IDE config" to
+`curl -fsSL .../ocp-connect | bash -s -- <ip>`. The OCP pattern works on
+trusted family LAN deployments; it would catastrophically fail on a public
+internet deployment. ADR 0011 makes the trust assumption explicit before OLP
+inherits the pattern.
+
+The ADR also pins three implementation details that are NOT obvious from
+reading the D69 patch alone:
+
+1. The plaintext token must live on disk SOMEWHERE for the server to surface
+   it. ADR 0007 § 5 + § 6.2 explicitly forbid plaintext storage in the
+   default manifest. D69 introduces an explicit **opt-in** `plaintext_advertise`
+   manifest field for ONLY the advertised key — every other key retains the
+   ADR 0007 § 5 hash-only contract.
+2. The advertised key is **guest-tier**, not owner-tier. Owner-tier
+   advertisement is rejected at keygen time AND at config-load time —
+   exposing the owner identity unauthenticated would grant any LAN caller
+   `/health` full payload, `/v0/management/*` mutating access, and
+   `X-OLP-Fallback-Detail` visibility — the exact inverse of the advertise
+   key's intent (a low-privilege zero-config tier).
+3. Three prerequisites MUST hold simultaneously for `/health.anonymousKey`
+   to be emitted; missing any one is logged at startup but the server still
+   boots — graceful-degrade rather than refuse-to-start.
+
+---
+
+## Decision
+
+### Three-prerequisite gate (server-side)
+
+`/health` emits the `anonymousKey` field if and only if ALL THREE hold:
+
+1. `auth.advertise_anonymous_key === true` in `~/.olp/config.json` (default
+   `false` — opt-in).
+2. `auth.allow_anonymous === true` (the anonymous tier must be reachable for
+   the advertised key to be meaningful to zero-config callers; advertising a
+   key into a deployment that rejects anonymous requests is incoherent).
+3. At least one active (`revoked_at === null`) manifest under `~/.olp/keys/`
+   carries a non-empty `plaintext_advertise: "olp_..."` field.
+
+When prerequisite (1) holds but (2) or (3) fails, the server logs a
+startup warn (`anonymous_key_advertised_but_denied` or
+`anonymous_key_advertised_but_no_anonymous_key_exists`) but starts normally
+and simply omits the field from `/health` responses.
+
+### Plaintext storage mechanism (`plaintext_advertise` manifest field)
+
+ADR 0007 § 5 forbids plaintext storage anywhere. D69 introduces a single,
+**explicitly opt-in** exception: the manifest of the designated advertised
+key gains a `plaintext_advertise` field whose value is the plaintext token.
+
+This field is written ONLY when the operator runs:
+
+```
+olp-keys keygen --anonymous --advertise
+```
+
+(or `--advertise` alone on a guest-tier `keygen` invocation; `--anonymous`
+is a friendly shorthand for `--tier=guest --name=anonymous`). The keygen
+command surfaces an explicit `WARNING` to stderr at creation time:
+
+```
+WARNING: this key's plaintext is now stored on disk + will be exposed via
+         /health.anonymousKey when auth.advertise_anonymous_key=true AND
+         auth.allow_anonymous=true. Use ONLY on a trusted LAN. See ADR 0011.
+```
+
+Every other key (every existing key, and every newly-created key without
+`--advertise`) retains the ADR 0007 § 5 hash-only contract — `manifest.json`
+contains `token_hash` and NEVER `plaintext_advertise`.
+
+**Schema-version note (D69 reviewer P2-2).** This adds a new optional field
+to the manifest. Per ADR 0007 § 4 ("Increment `schema_version` on any
+non-additive change"), additive optional fields do NOT require a
+`schema_version` bump — older parsers ignore unknown fields per the same
+section's forward-compat rule. The manifest stays at `schema_version: 1`.
+Documented here so a future archaeologist asking "why didn't D69 bump
+`schema_version`?" has a one-line answer.
+
+**`listKeys()` redaction (D69 reviewer P2-1).** `lib/keys.mjs listKeys()`
+strips BOTH `token_hash` AND `plaintext_advertise` from its return value.
+Callers wanting the advertised plaintext for the `/health` publication
+path MUST go through `findAdvertisedKey()` — the only sanctioned read
+site. This protects against a future caller of `listKeys()` accidentally
+emitting the plaintext into logs / HTTP responses / dashboards.
+
+### Tier restriction (guest only)
+
+`createKey()` rejects `plaintext_advertise: true` for `owner_tier: 'owner'`
+with the error `createKey: plaintext_advertise requires owner_tier="guest"`.
+The CLI also rejects `--owner --advertise` with a clear error pointing at
+this ADR.
+
+Rationale: owner-tier confers `/health` full payload visibility,
+`/v0/management/*` mutating access, and `X-OLP-Fallback-Detail` header
+visibility. Advertising owner-tier plaintext unauthenticated would let any
+LAN caller assume the owner identity — the exact opposite of the design
+intent.
+
+### Trusted-LAN deployment invariant
+
+`auth.advertise_anonymous_key: true` is permitted ONLY when the OLP server
+is bound to a trust-equivalent address space:
+
+| Tier | Address space | Permitted? |
+|------|---------------|------------|
+| Loopback | `127.0.0.0/8` | yes |
+| RFC 1918 LAN | `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16` | yes |
+| Tailnet | `100.64.0.0/10` (CGNAT range used by Tailscale) | yes |
+| Localhost domains | `localhost`, `*.local`, `*.internal` | yes |
+| Public internet | any routable IPv4/IPv6 outside the above | NO |
+
+This is a **soft constraint** at v0.4.0 — OLP does not enforce IP-allowlist
+or BIND_ADDRESS inspection. The constraint is documented here, surfaced in
+README § "Anonymous-key advertise mode (trusted-LAN-only)", and warned-but-
+not-blocked at server startup when `auth.advertise_anonymous_key=true` and
+the bind address looks public.
+
+Hard enforcement (refuse to start when bind is public + advertise enabled)
+is deferred. The maintainer's deployments are LAN-only, the family-scale
+audience cannot tolerate a startup-refuse mode that bricks the proxy on
+ambiguous network topology (e.g., TLS-fronted private network where the
+underlying bind IP IS public but the network itself is trusted), and the
+trade-off in ADR 0010 explicitly accepted operator-discretion gates for
+soft constraints of this class.
+
+---
+
+## Threat model
+
+The advertised anonymous key is **public** within the boundary of "anyone
+who can reach `GET /health`." Anyone within that boundary can read the
+plaintext from `/health.anonymousKey` and use it for `/v1/chat/completions`,
+`/v1/models`, etc.
+
+| Deployment | Boundary | Acceptable? |
+|------------|----------|-------------|
+| Mac mini + Tailscale, only family devices on tailnet | family devices | YES |
+| Home LAN with no guest WiFi, no port-forward | household + neighbors-within-WiFi-range | YES (within risk tolerance) |
+| Home LAN with guest WiFi joined to same VLAN as proxy | EVERYONE who visits and connects to guest WiFi | borderline; treat with caution |
+| Coffee shop / open WiFi | EVERYONE physically present | NO |
+| Public internet via Cloudflare Tunnel / port-forward / VPS | EVERYONE on the internet | NO — instant compromise |
+
+The capability gain for an attacker who reads `/health.anonymousKey` is
+**equal to the capability the operator deliberately granted the
+anonymous-tier key**:
+
+- `providers_enabled` (when `'*'`, the attacker can dispatch any provider —
+  burning the operator's subscription quotas).
+- `/v1/chat/completions` access (LLM use under the operator's billing).
+- Cache pollution under `__anonymous__` namespace (per ADR 0007 § 7.1; the
+  advertised guest key uses its own `<key-id>` namespace — but anonymous
+  callers who DON'T present the key use `__anonymous__`).
+
+What the attacker does NOT get:
+
+- `/health` full payload — gated to `owner_tier === 'owner'` (ADR 0007 § 7.1).
+- `/v0/management/*` mutating endpoints — gated to owner (ADR 0008 § 7).
+- `X-OLP-Fallback-Detail` header — `'owner_only'` policy default (ADR 0007 § 7.2).
+- The owner key's plaintext (which is never stored anywhere; only its
+  `token_hash` is on disk per ADR 0007 § 5).
+
+The "burn the operator's subscription quotas" failure mode is bounded by
+the per-provider quota limits AND the maintainer's monitoring (`/health`
+owner-view shows quota status per provider; `/v0/management/audit` shows
+per-key usage). Detection is fast; the question is how much quota the
+attacker can burn between compromise and key revocation.
+
+---
+
+## `olp-connect` integration (D68 client-side)
+
+`bin/olp-connect <ip>` queries `GET /health` as its first action. If the
+response contains `anonymousKey: "olp_..."`, the script uses that value
+silently for the rest of the run (printing a one-line `Using server-
+advertised anonymous key: olp_...XXXX` notice + a pointer to this ADR).
+This is what makes `olp-connect <ip>` a true zero-config command — no
+out-of-band token paste needed.
+
+If `anonymousKey` is absent (the default, when `auth.advertise_anonymous_key`
+is false), the script falls back to interactive prompt or `--key` flag.
+
+`olp-connect` does NOT perform any of the trusted-LAN soft-checks itself —
+it trusts that an operator who set `auth.advertise_anonymous_key: true`
+knows their deployment context. The script does, however, document the
+trade-off in its `--help` output and prints the ADR 0011 reference
+alongside the "using server-advertised key" notice.
+
+---
+
+## Deployment configurations (D76 amendment, 2026-05-26)
+
+Original ADR 0011 referenced a `BIND_ADDRESS` concept that did not exist in the v0.4.0–v0.4.2 codebase — the server was hard-coded to `server.listen(PORT, '127.0.0.1', ...)`. D76 closes this gap by adding the `OLP_BIND` env var (default `127.0.0.1`), making the deployment-context discussion below operational rather than aspirational.
+
+Three deployment configurations are supported:
+
+| `OLP_BIND` value | Reachability | Anonymous-key publication |
+|---|---|---|
+| `127.0.0.1` (default) | Loopback only | Safe with any auth posture (no LAN exposure at all) |
+| RFC1918 IP / tailnet IP / `0.0.0.0` on a trusted LAN | LAN clients only | Safe when `advertise_anonymous_key: true` — the documented "trusted-LAN" zero-config family onboarding flow |
+| Public IP / `0.0.0.0` on a public-facing host | Public internet | **Incompatible with `advertise_anonymous_key: true`.** Operator MUST keep `advertise_anonymous_key: false` (default). |
+
+The server emits a startup warn event `anonymous_key_advertised_with_lan_bind` when `OLP_BIND` is non-loopback AND `advertise_anonymous_key: true` (per the `lib/keys.mjs` + `server.mjs` checks). The warn is a **checkpoint, not a hard gate** — the server cannot tell from the bind address alone whether the operator is on a trusted LAN (RFC1918 / tailnet) or has accidentally exposed a public IP. The Re-evaluation trigger #1 below escalates to a hard gate when OLP gains a public-internet deployment mode.
+
+`olp-connect <ip>` consumes `/health.anonymousKey` over the network — therefore requires `OLP_BIND` to include the LAN interface on the server side. Without setting `OLP_BIND=<lan-ip>` (or `0.0.0.0`), `olp-connect <ip>` will fail with `connect ECONNREFUSED` because the server only accepts loopback connections.
+
+---
+
+## Re-evaluation triggers
+
+Re-open this ADR when ANY of the following fires:
+
+1. OLP gains a "expose to public internet" deployment mode in the README
+   (e.g., Cloudflare Tunnel guidance, ngrok recipe). At that point the
+   soft-constraint MUST become a hard constraint (bind-address inspection
+   at startup, refusal to enable `advertise_anonymous_key` when bind is
+   public — likely with a separate `OLP_TRUSTED_PUBLIC_OVERRIDE=1` env
+   escape hatch for operators who run their own TLS termination).
+2. The OCP `/health.anonymousKey` model is found to have caused a
+   real-world quota-burn incident; that learning amends this ADR.
+3. Phase 5 introduces multi-tenant SaaS-like deployments (currently
+   non-goal per ADR 0001); the entire family-scale assumption is
+   re-examined.
+
+---
+
+## Consequences
+
+**Positive.**
+
+- Family-member onboarding becomes a single command: `olp-connect <ip>`. No
+  out-of-band token paste. No "wait, what's the API key?" friction loop.
+- The trust trade-off is now an explicit, single-knob config decision, not
+  an implicit consequence of OCP-pattern inheritance.
+- The `plaintext_advertise` field is a single auditable on-disk surface —
+  `grep plaintext_advertise ~/.olp/keys/*/manifest.json` answers "which key
+  is advertised?" definitively, and an operator who wants to disable the
+  feature can simply revoke that key.
+- Owner-tier advertisement is impossible (both at keygen and at config
+  load), eliminating an entire class of foot-gun.
+
+**Negative.**
+
+- ADR 0007 § 5's "no plaintext on disk, ever" property is weakened to "no
+  plaintext on disk except for ONE explicitly-opted-in field on ONE key."
+  The exception is narrow and audit-grep-able but the property is no
+  longer absolute.
+- Operators who enable advertise mode then move the deployment from LAN to
+  public internet (e.g., add a Cloudflare Tunnel without revisiting the
+  config) silently invert the threat model. The startup warn for "public
+  bind detected" does not currently fire (soft constraint per § "Trusted-
+  LAN deployment invariant" above).
+- The OCP precedent shows operators sometimes share `olp-connect <ip>`
+  invocations in chat / docs that include their IP; an LLM training corpus
+  could harvest these IPs. The advertised key is only useful while the
+  network reaches the IP, but the IP-disclosure surface grows.
+
+**Neutral.**
+
+- The plaintext storage is per-key, not global. Revoking the advertised key
+  removes the plaintext exposure within one filesystem write (the manifest
+  stays on disk for audit attribution per ADR 0007 § 6.1, but `revoked_at`
+  becomes non-null and `findAdvertisedKey()` skips revoked manifests).
+
+---
+
+## Alternatives considered
+
+1. **Store plaintext in `config.json` directly.** Rejected. Mixes secrets
+   with operational config; complicates git-crypt boundary; loses the
+   per-key revocation path (you'd have to edit JSON to "revoke" the
+   exposure rather than running `olp-keys revoke --id=<id>`).
+2. **Add an `anonymous` owner_tier instead of using `guest` + `plaintext_
+   advertise`.** Rejected. Bumps ADR 0007 § 4 schema version (a
+   non-additive change), adds a third identity class that the rest of the
+   codebase (cache namespacing, /health gating, audit attribution) has no
+   reason to know about, and conflicts with ADR 0007 § 7.1's "anonymous =
+   no auth header + allow_anonymous=true" definition. A single optional
+   field on the manifest is strictly less invasive.
+3. **Hard-enforce trusted-LAN bind address at startup.** Rejected for
+   v0.4.0; deferred until a public-deployment-mode README section ships
+   (see Re-evaluation triggers § 1). Soft constraint + startup warn is
+   appropriate while OLP has zero public-internet deployment recipes.
+4. **Encrypt `plaintext_advertise` at rest with a key derived from
+   `OLP_HOME` path or a separate `OLP_ADVERTISE_KEY` env var.** Rejected.
+   The threat model is "anyone who can read `/health` reads the plaintext
+   token over the wire," not "anyone who can read `~/.olp/keys/`." Both
+   require LAN-reach; encrypting on-disk doesn't change the over-the-wire
+   exposure. Adds complexity for no security gain in the relevant attack
+   model.
+5. **Make `--advertise` allowed only when `--name` is exactly `anonymous`.**
+   Rejected as over-restrictive. The CLI's `--anonymous` shorthand
+   defaults `--name=anonymous`, but operators may legitimately want a
+   named advertised key (e.g., `family-guest`, `lan-zero-config`). The
+   discriminator is the field, not the name.

+# ADR 0012 — Phase 5 Charter: Provider Quota Probes + Dashboard Enrichment
+
+**Status:** Accepted (Phase 5 open as of 2026-05-26)
+**Date:** 2026-05-26
+**D-day:** D79 (charter + ADR 0002 Amendment 8 + ADR 0013 land together as the constitutional layer of Phase 5)
+
+## Amendments
+
+### Amendment 1 — 2026-05-26: D84 Mistral probe NO-GO (post-D79-close spike)
+
+The D-day table originally listed D84 as "optional, depends on D79-close 30-min Mistral docs spike". The spike completed 2026-05-26 with verdict **NO-GO** — Mistral does not expose a programmatic quota/usage endpoint **accessible to Vibe / Le Chat member / La Plateforme API keys** (the key tier OLP uses for spawning the `vibe` CLI):
+
+- `docs.mistral.ai/api` (the public API spec) covers Chat, FIM, Embeddings, Classifiers, Files, Models, Batch, OCR, Audio, Events, Beta (Agents/Conversations/Libraries/Workflows/Observability). No usage/quota/credits/billing/limits endpoint accessible to a member API key.
+- Direct probe `https://api.mistral.ai/v1/usage` returns 404.
+- Mistral's "Limits and Usage" help article documents limit viewing via the `admin.mistral.ai/plateforme/limits` web console.
+- No `x-ratelimit-*` response headers documented on `/v1/chat/completions`. (Third-party summaries mentioning these headers are unsourced — appears to be OpenAI-convention extrapolation.)
+- OLP `lib/providers/mistral.mjs` already records this independently — DL-7 comment: "If quota/budget API surfaces in Le Chat Pro, pin the endpoint here."
+
+**Out-of-scope but worth pinning for future revisit.** Mistral's [Admin API](https://docs.mistral.ai/admin/security-access/admin-api) DOES expose programmatic "Billing and usage queries", and the [Usage limits docs](https://docs.mistral.ai/admin/user-management-finops/usage-limits) describe usage/cost queries via that surface. The Admin API requires an **org-admin scoped API key** (separate from the member key OLP uses). For OLP's family-tier deployment posture (a maintainer's personal Le Chat Pro / La Plateforme account, not an organization's admin console), provisioning + storing an org-admin token raises the credential-scope ceiling beyond what the trusted-LAN deployment context (ADR 0011) was designed for. The NO-GO at v0.5.0 is therefore "out of scope for OLP's current deployment posture", NOT "Mistral has no programmatic surface". If the deployment posture expands to an org-admin context (e.g., a small-business multi-user deployment), this decision should be re-evaluated.
+
+**Disposition:**
+- D84 row dropped from D-day plan (struck through below).
+- Mistral dashboard row in D82 UI shows "spend tracking only" badge sourced from `audit-query.mjs` aggregates (request count, estimated cost from `estimateCost()`).
+- `DL-7` in `mistral.mjs` is the documented re-entry point if Mistral ever publishes a usage endpoint.
+- Phase 5 total D-day budget revised: ~5 D-days (down from ~6).
+
+---
+
+## Context
+
+Phase 4 (ADR 0010) shipped OLP's operator + client UX layer — `bin/olp` operator CLI, `olp doctor` framework, `olp-connect` zero-config IDE wiring, OpenClaw `/olp` slash commands, anonymous-key deployment-context limits, SSE heartbeat. v0.4.4 is the current shipped state. Phase 4 closed every gap on the OCP-feature-parity matrix EXCEPT one: **live quota / plan-usage surfacing**.
+
+Today `lib/providers/anthropic.mjs:445` has a stub `quotaStatus()` returning `null` (D4 placeholder). The OLP dashboard's quota panel renders "—" for all providers. OCP, in contrast, exposes a live "39% session / 30% weekly" panel — the maintainer uses this multiple times per day to decide when to throttle voluntary `claude -p` traffic away from interactive sessions. OLP cannot become an OCP successor in practice (vs. just feature-parity-on-paper) until quota surfacing works.
+
+A pre-flight institutional-knowledge audit (2026-05-26 — see `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`) confirmed:
+
+1. **The OCP probe still works today** — Anthropic returns the same `anthropic-ratelimit-unified-*` headers on every `POST /v1/messages` call. Tested live 2026-05-26 from PI231 OAuth credentials.
+2. **Schema added 3 fields since OCP's 2026-04 capture** — `5h-status`, `7d-status` (per-window status), `overage-reset` (only on active overage). No fields removed or renamed.
+3. **Verification protocol has shifted** — Claude Code v2.1.x is now a **compiled binary** (Mach-O / ELF), not bundled JS. OCP's "grep cli.js" approach no longer applies; the replacement protocol is `strings` against the binary + periodic live probe diff.
+4. **OAuth refresh path unchanged** — `platform.claude.com/v1/oauth/token` + `9d1c250a-...` client_id + 60s-3600s exponential backoff.
+
+The audit makes Phase 5 implementation low-risk: this is a port of a working OCP function, not a re-derivation. The work is mechanical + adapter-layer plumbing into OLP's plugin contract.
+
+A parallel maintainer request (2026-05-26, with reference screenshot of claude.ai/settings/usage) asked for Claude.ai-style dashboard enrichment: per-row utilization bars, reset countdown, 1-minute auto-refresh, manual refresh button. P5-1 (probe) + P5-2 (dashboard) together unlock both: the data plus the surface. v1.x roadmap #8 is closed by P5-2.
+
+---
+
+## Decision
+
+Phase 5 scope is **Provider quota probes + dashboard enrichment**. The phase opens 2026-05-26 with D79 (this charter + ADR 0002 Amendment 8 + ADR 0013 OAuth READ-ONLY consumption rules). Phase 5 close ships v0.5.0; per `CLAUDE.md release_kit.phase_rolling_mode`, the close PR is maintainer-triggered.

+### Out of Phase 5 scope (with explicit triggers)
+
+#### `X-OLP-Cost-USD` per-request response header
+
+**Status:** Deferred to Phase 6. Was listed in ADR 0010 § Out-of-scope as "Phase 5 prerequisite". The prerequisite (provider-cost weights table) is non-trivial — needs per-(provider, model) `input_cost_per_1k_tokens` / `output_cost_per_1k_tokens` / `cache_read_discount` data sourced from each provider's published pricing page. Phase 5 already pulls in two new ADRs; adding a third data-onboarding ADR is scope creep.
+
+**Re-open condition.** Phase 6 unless a maintainer reports a cost-attribution debugging need that warrants pulling forward.
+
+#### `context_window_exceeded` fallback trigger (LiteLLM prior-art)
+
+**Status:** Deferred. ADR 0010 listed this as opportunistic-in-Phase-5 unless the trigger fires sooner. The trigger has not fired in Phase 4 production traffic. Continue to defer.
+
+#### per-(provider, model) live stats Map (replacing audit-query scan)
+
+**Status:** Deferred. Current scan latency is ~20ms at 7-day depth. Acceptable until volume grows (>100k requests/day). Re-evaluate at Phase 6 if dashboard latency degrades.
+
+#### Anthropic interactive-mode P0 (ADR 0009)
+
+**Status:** Still trigger-gated on Anthropic's 2026-06-15 billing-split rollout. Phase 5 does NOT depend on P0 — the quota probe reads `anthropic-ratelimit-unified-*` headers regardless of which billing pool the spawn path consumes. If P0 succeeds Phase 7+ Phase 5's probe code remains unchanged; if P0 fails Phase 5's probe code remains unchanged. The probe is billing-pool-agnostic because the headers are subscription-pool metadata, not Agent-SDK-Credit metadata.
+
+#### `/v1/messages` Anthropic-shape entry surface
+
+**Status:** Still deferred per ADR 0010 § Out-of-scope. No change in Phase 5.
+
+#### v1.x roadmap #3 / #5 / #6
+
+**Status:** Still trigger-gated per `docs/v1x-roadmap.md`. None has fired. Continue to defer.
+
+### Opportunistic Phase 5 micro-additions (not blocking)
+
+Items small enough to land alongside a planned D-day without scope creep, if encountered:
+
+- README § Dashboard screenshot update (post-P5-2 enrichment) — capture from MacBook test path per `~/.cc-rules/memory/feedback/mac_mini_never_for_testing.md`.
+- `olp usage` CLI subcommand (bin/olp.mjs) surfaces the parsed quota shape in terminal form. Already partially exists (cmdUsage in bin/olp.mjs); confirm payload alignment after D80.
+- Add `claude_code_oauth_client_id` config override in `~/.olp/config.json` so power users can override the hardcoded `9d1c250a-...` UUID without env-var fiddling. Mirrors compiled binary's `CLAUDE_CODE_OAUTH_CLIENT_ID` env support.
+- `docs/provider-audits/anthropic.md` re-capture with current `claude --version` (v2.1.142 MacBook / v2.1.150 PI231) + binary distribution layout note.
+
+### Exit gate — v0.5.0 close criteria
+
+1. D79 — D84 all merged with fresh-context opus reviewer APPROVE per Iron Rule 10.
+2. CI green on every D-day merge commit and on the v0.5.0 release commit head. `alignment.yml` blacklist re-confirmed (no new hallucinated tokens introduced).
+3. README § Quota / Plan Usage section present with screenshot of the enriched dashboard. README § Supported Providers table updated to note "quota probe: anthropic ✅, mistral ⚠️/✅ (D84 outcome), codex ❌ (no public API)".
+4. ADR 0012 (this charter) + ADR 0002 Amendment 8 + ADR 0013 (OAuth READ-ONLY consumption) on disk.
+5. `CHANGELOG.md "Unreleased"` promoted to `"## v0.5.0 — <date>"` with D79 — D84 entries.
+6. `package.json` bumped to `0.5.0`.
+7. `CLAUDE.md release_kit.phase_rolling_mode.current_phase` advances `Phase 5 → Phase 6`; `current_pre_release_identifier` advances `0.5.0-phase5 → 0.6.0-phase6`.
+8. Standing autopilot grant covers D-day-by-D-day execution; v0.5.0 close PR is maintainer-triggered.
+9. Live MacBook E2E verification — dashboard renders enriched panel with real quota data (probe live, not mocked).
+
+---
+
+## Consequences
+
+**Positive.**
+
+- OLP finally has the load-bearing observability OCP had — maintainer can see live "39% session / 30% weekly" and decide whether voluntary `claude -p` traffic stays or moves.
+- Family members on the LAN see real reset times instead of "—", which makes the "wait 2 hours" guidance concrete vs. abstract.
+- The institutional-knowledge audit captured the schema in a memory file pinned with date stamps — future ports (mistral, future provider) re-use the verification protocol without re-deriving.
+- v1.x roadmap #8 (Dashboard enrichment per Claude.ai-style usage page) closes inside Phase 5 rather than waiting for a separate phase.
+- Compiled-binary-distribution awareness ("no more cli.js to grep") is now codified in OLP governance; the next time Anthropic ships a major CC version, the verification protocol is already written.
+
+**Negative.**
+
+- ADR 0002 gains another amendment (Amendment 8). The constitution surface area for `anthropic.mjs` grows. Counter-pressure: the alternative (probe lives in `server.mjs`, like OCP) violates the plugin-architecture principle that per-provider knowledge stays in `lib/providers/`. Amendment 8 is the smaller violation.
+- The probe makes one `/v1/messages` call per 5min cache miss. That's ~12 calls/hour worst case across the whole proxy (probe is per-credentials, not per-key). With `max_tokens: 1` the cost is < $0.01/day at family-scale traffic. Negligible but not zero.
+- Schema-drift risk over the long horizon. Anthropic could rename or remove headers in a future version. The mitigation protocol (strings + live probe diff) is in place, but it's a manual check — needs to be invoked by the maintainer or scheduled.
+- Dashboard refactor introduces a breaking-change risk for the existing dashboard.html consumers (none today, but conceptually). Bumping to v0.5.0 signals this clearly.
+
+**Neutral.**
+
+- Phase 5 has more ADR work than Phase 4 (3 governance docs vs. 2). The constitutional layer is deliberately heavier because direct-API access is the single biggest authority decision since the plugin contract itself.
+
+---
+
+## Authority + cross-references
+
+- **Iron Rule 11 (IDR)** — Phase 5 ships across 6 D-days, each a minimum reviewable unit. The governance trio (this ADR + Amendment 8 + ADR 0013) lands at D79 as a single coupled commit (reviewing them separately cannot verify consumer-producer alignment), per ADR 0002 Amendment 7's precedent.
+- **Iron Rule 12 (prior-art search)** — discharged via the audit memory at `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`. Memory committed prior to D80 implementation.
+- **ALIGNMENT.md Rule 1 (citation)** — D80 commit must cite compiled-binary `strings` evidence per audit memory § Path A (Claude Code v2.1.x has no traditional `§ section` structure because it is a Mach-O / ELF compiled binary) plus the audit memory file path. Live-probe transcript MUST be included in the commit body.
+- **ALIGNMENT.md Rule 2 (provider-CLI-as-authority)** — direct-API access bypasses the spawn-binary contract. Amendment 8 is the explicit exemption. Without Amendment 8, the D80 commit is unalignable.
+- **ALIGNMENT.md Rule 5 (CI alignment.yml)** — must continue to pass. `api.anthropic.com/v1/messages` is NOT on the blacklist (correct — that's the real endpoint). The hallucinated `/api/oauth/usage` IS on the blacklist (transitive from OCP) and must remain.
+- **ADR 0002 Amendment 8** — companion ADR. Direct-API access scoping; READ-ONLY constraint; opt-in via config flag (default off).
+- **ADR 0013** — companion ADR. OAuth credentials shared between spawn path + probe path; refresh backoff; schema-drift mitigation protocol.
+- **CLAUDE.md release_kit** — Phase boundary triggers maintainer-led version bump. D-day commits within Phase 5 stay under "Unreleased". `0.5.0-phase5` is the pre-release identifier during the phase.

+# ADR 0013 — OAuth READ-ONLY Consumption Rules + Schema-Drift Mitigation Protocol
+
+**Status:** Accepted (2026-05-26)
+**Date:** 2026-05-26
+**D-day:** D79 (lands alongside ADR 0012 Phase 5 charter + ADR 0002 Amendment 8 as the constitutional trio of Phase 5)
+
+---
+
+## Context
+
+ADR 0002 Amendment 8 permits `quotaStatus()` to call provider HTTP APIs directly, subject to a READ-ONLY constraint. That Amendment opens the door but does not specify HOW READ-ONLY discipline is preserved across credential lifecycle events (refresh, expiry, revocation), nor how OLP detects when the upstream API schema drifts. ADR 0013 fills both gaps.
+
+The motivating concern: a provider that ships its CLI as a **compiled native binary** (Anthropic Claude Code v2.1.x is now Mach-O on macOS, ELF on Linux) closes off the previous schema-verification path (grep `cli.js`). If OLP's probe parser silently breaks because a header was renamed, the dashboard shows stale or wrong numbers, and the maintainer's load-bearing throttling decision is based on bad data. This ADR establishes the verification protocol that survives the binary-distribution shift.
+
+A second motivating concern: the OAuth credentials used by the probe are the SAME credentials the spawn path uses for `claude -p`. Both paths consume them; the probe must not interfere with the spawn path's ability to refresh or invalidate them. Concretely: the probe must not write to the credentials artifact, must not race the spawn path on refresh, and must not amplify a 429 into a refresh storm.
+
+---
+
+## Decision
+
+### Rule 1 — Credential reuse is mandatory
+
+The probe MUST consume the same OAuth artifact the spawn path reads via the plugin's `readAuthArtifact()`. No new OAuth grant. No alternate credential store. No environment-variable-only fallback (env var `CLAUDE_CODE_OAUTH_TOKEN` is supported as an override consistent with the spawn path, but is not the probe's primary source).
+
+Precedence order (mirrors OCP `getOAuthCredentials` 2026-04-stable):
+
+1. `process.env.CLAUDE_CODE_OAUTH_TOKEN` if non-empty (manual override; common in CI / dev / one-off debugging).
+2. `~/.claude/.credentials.json` → `claudeAiOauth.accessToken` (Linux + macOS without keychain access).
+3. macOS Keychain: `security find-generic-password -a "${USER}" -s "Claude Code-credentials" -w` (preferred on macOS — current `lib/providers/anthropic.mjs` only covers (1) + (2); D80 adds (3)).
+
+Rationale: a separate OAuth grant would require the maintainer to repeat `claude setup-token` against an OLP-specific scope, doubling credential exposure and divergence risk. Reusing the spawn path's credentials guarantees the probe never has more permission than the spawn path itself.
+
+### Rule 2 — READ-ONLY at the wire
+
+The probe MUST issue exactly one HTTP request per cache miss. Method MAY be POST (Anthropic's ratelimit headers come back on `POST /v1/messages`; this is the only way to read them). Request body MUST minimise side effects:
+
+- `max_tokens: 1` (cost: ~$0.000001 per probe)
+- `messages: [{role: "user", content: "hi"}]` (any minimal valid payload)
+- Model: cheapest available in the plan (`claude-haiku-4-5` at v0.5.0)
+- Do NOT include `system` prompts, `tools[]`, `tool_choice`, large content arrays, or anything that the upstream might bill differently.
+
+The probe MUST discard the response body. Only response headers are parsed.
+
+The probe MUST NOT call any other HTTP path on the provider's API. No `/v1/models` enumeration, no admin endpoints, no `/v1/messages/<id>` retrievals. The only permitted endpoint is `POST /v1/messages`.
+
+### Rule 3 — Cache TTL and refresh discipline
+
+- Cache TTL: 5 minutes. Cache miss triggers a real probe. Cache hit returns the cached value.
+- The dashboard refreshes every 1 minute; that's served from the cache between probes. A manual refresh button MAY force-clear the cache (per maintainer request 2026-05-26); ADR 0012 D82 documents the button.
+- On refresh failure (token expired, 401/403/429, network error), the probe schedules an exponential backoff: minimum 60s, maximum 3600s. The cache entry is NOT invalidated during backoff; `quotaStatus()` returns the stale cache marked `{ stale: true, last_fresh_at: <epoch> }`. If no stale entry exists, returns an `unreachable` shape (v0.5.1+) rather than `null`.
+- Successive successful probes reset the backoff to the minimum.
+- Token refresh (`POST https://platform.claude.com/v1/oauth/token`) follows the same backoff discipline. The probe MUST NOT refresh a token more than once per backoff window. The refresh path is shared with the spawn path; both observe the same backoff.
+- **All consumers of `quotaStatus()`, including `olp doctor` checks, MUST route through `quotaStatus()` and MUST NOT call `_probeOnce()` directly.** `_probeOnce()` is an internal implementation detail. Routing doctor checks through `quotaStatus()` ensures the cache+backoff discipline is enforced for every caller — including operators running `olp doctor` in a debug loop. (Clarification added v0.5.1 to address codex finding F1: the original doctor check bypassed backoff by calling `_probeOnce` directly.)
+
+### Rule 4 — Opt-in via config
+
+A new config field at `~/.olp/config.json` controls per-provider opt-in:
+
+```json
+{
+  "providers": {
+    "anthropic": {
+      "enabled": true,
+      "quota_probe_enabled": false
+    }
+  }
+}
+```
+
+Default: `false`. The maintainer must explicitly opt in after credentials are configured. Reasoning: a fresh install on a machine without OAuth credentials should not bombard `api.anthropic.com` with 401-bound probes.
+
+`olp doctor` adds a per-provider check `<provider>.quota_probe_reachable` (only runs if `quota_probe_enabled: true`). Failed check provides a `next_action.ai_executable[]` recipe to either re-authenticate or disable the probe.
+
+### Rule 5 — Schema-drift mitigation protocol (minimum-viable-schema gate)
+
+The CC binary-distribution shift means OCP's "grep cli.js" verification is no longer applicable. OLP adopts a two-path protocol for proactive monitoring, AND enforces a minimum-viable-schema gate at parse time:
+
+**Minimum-viable-schema gate (v0.5.1+).** `_probeOnce()` requires at least these 4 fields present (non-null after parse) before treating a response as successful:
+- `anthropic-ratelimit-unified-5h-utilization`
+- `anthropic-ratelimit-unified-5h-reset`
+- `anthropic-ratelimit-unified-7d-utilization`
+- `anthropic-ratelimit-unified-7d-reset`
+
+If any of these 4 is absent, `_probeOnce()` classifies the probe as a schema-drift failure (`failureKind = 'schema_drift'`), schedules backoff, and returns `null`. This means a 200 OK with zero `anthropic-ratelimit-*` headers (e.g. a server-side change, a proxy stripping headers, or a mock returning `{}`) is immediately caught as drift rather than silently cached as "live" data. The other 9 fields are tolerated as absent (overage fields are conditional; top-level status fields may be absent on edge cases). The 5h/7d core 4 are load-bearing — the dashboard's progress bars depend on them. (Gate added v0.5.1 to address codex finding F2.)
+
+The CC binary-distribution shift means OCP's "grep cli.js" verification is no longer applicable. OLP adopts a two-path protocol:
+
+**Path A — Compiled-binary string extraction.** Run `strings` over the platform-specific binary in the claude-code distribution. Captures all hardcoded header names the binary expects:
+
+```bash
+BIN_DIR=$(npm root -g)/@anthropic-ai/claude-code/node_modules/@anthropic-ai/claude-code-*
+strings "$BIN_DIR/claude" | grep -iE "anthropic-ratelimit|/v1/(messages|oauth)|platform\.claude\.com"
+```
+
+**Path A prerequisites.** GNU or BSD `strings` (part of binutils/coreutils on Linux + macOS — always present on a normal developer machine; Windows requires WSL or `binutils-mingw`). A locally installed Claude Code v2.1.x (npm-global or volta-managed). A reviewer without `claude` installed can still run Path B but Path A is gated on having the binary on disk. A future Claude Code version that ships as a different distribution shape (e.g. Rust binary, statically linked Go) keeps the protocol valid: `strings` works on any ELF/Mach-O regardless of compile source.
+
+**Path B — Live API probe.** Run the actual probe against `api.anthropic.com` with valid OAuth credentials. Captures what the server returns today:
+
+```bash
+curl -s -i -m 10 -X POST https://api.anthropic.com/v1/messages \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "anthropic-beta: oauth-2025-04-20" \
+  -H "anthropic-version: 2023-06-01" \
+  -H "Content-Type: application/json" \
+  -d '{"model":"claude-haiku-4-5","max_tokens":1,"messages":[{"role":"user","content":"hi"}]}' \
+  | grep -iE "^anthropic-ratelimit"
+```
+
+Path A tells you what the client expects. Path B tells you what the server actually emits. The diff is the actionable schema delta.
+
+**Required cadence.** The diff MUST be re-run at every major `claude --version` bump (v2.x → v3.x is the next trigger). The current pinned schema lives at `~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`. After re-verification, that memory file MUST be updated (or a successor file written with a new date stamp; the old one cross-linked).
+
+**Trigger for re-running the diff.** There is no automated detector for a major `claude --version` bump at v0.5.0. Three explicit hooks share this responsibility:
+
+1. **Annual Alignment Audit** (`ALIGNMENT.md` § Annual Alignment Audit, every 14 May) — diff is mandatory as part of the audit checklist.
+2. **`olp doctor anthropic.quota_probe_reachable` failure** — if the probe returns non-2xx for any reason other than 401/403/429/network (typical schema breaks manifest as 422 or 400), `olp doctor` surfaces a `kind: fix_provider` recipe whose first step is "re-run the Rule 5 dual-path diff".
+3. **Manual maintainer attention at a major Claude Code release** — if the maintainer sees a major version bump in `claude --version`, kick off the diff before the next Phase opens. Rolling-mode discipline (CLAUDE.md release_kit) means major-version bumps usually intersect with Phase boundaries.
+
+If the diff is missed across a major version bump, the failure mode is graceful degradation: the parser silently drops unknown headers; the dashboard shows older values (cached stale) or `null` per Rule 3; `olp doctor` surfaces the staleness.
+
+**Required action on drift detection.** If a header is renamed or removed:
+
+1. File a Phase-N issue tagging the maintainer.
+2. Update the parser in `lib/providers/anthropic.mjs:quotaStatus()` to handle both names (graceful migration), prefer the new name.
+3. Update the audit memory file with a "drift event" section recording: date, old field, new field, evidence URLs.
+4. Bump the `models-registry.json` `quota_probe.schema_version` (NEW field added at D80) so downstream consumers can detect.
+
+If a new header appears in the live response that the parser doesn't read: low-priority enhancement; add to the parser, document in the audit memory, no schema_version bump required.
+
+### Rule 6 — Failure transparency
+
+The probe's failure modes are visible to the operator:
+
+- `/v0/management/dashboard-data` includes per-provider `{ quota_probe: { status: 'ok' | 'stale' | 'failed' | 'disabled', last_fresh_at, last_error?, backoff_until? } }`.
+- `olp doctor` surfaces probe failure as `kind: fix_oauth` (if 401/403) or `kind: fix_provider` (if 429 with no stale cache or network error).
+- The dashboard row badge shows the status; clicking a failed row shows the last error (truncated to 200 chars, no full credential traces).
+
+### Rule 7 — Out-of-scope
+
+This ADR does NOT govern:
+
+- Spawn-path OAuth refresh (the spawn path's refresh logic predates this ADR and is governed by the underlying CLI). The probe shares the credential artifact but does not own the refresh.
+- Anthropic-specific bearer revocation (Anthropic side). Revocation manifests as 401 to the probe, which falls into Rule 6.
+- Non-Anthropic provider OAuth flows. Mistral / future providers MAY adopt this protocol via plugin-specific ADRs; ADR 0013 establishes the template.
+
+---
+
+## Consequences
+
+**Positive.**
+
+- The probe is bounded — Rule 2 caps the wire traffic, Rule 3 caps the refresh rate, Rule 4 caps activation surface.
+- Schema-drift detection is procedural and reproducible — Rule 5 gives the maintainer a runbook that doesn't depend on Anthropic publishing a deprecation notice.
+- Failure is visible — Rule 6 means a broken probe shows up in `olp doctor` and the dashboard, not as a silent "—" in the quota row.
+- Credential reuse (Rule 1) keeps the security surface area minimal.
+
+**Negative.**
+
+- The `quota_probe_enabled` opt-in adds a configuration step. Mitigated by `olp doctor` surfacing the recipe when credentials are present but the probe is off.
+- The schema-drift protocol is manual. Anthropic could ship a v3.x binary tomorrow and the verification only happens when the maintainer or a doctor probe failure prompts it. Counter-pressure: drift events at OCP scale (~12 months) suggest manual verification on major version bumps is sufficient.
+- Stale-cache-on-failure (Rule 3) means the dashboard could show 30-minute-old data without an obvious "stale" indicator unless the UI explicitly renders the `stale: true` marker. ADR 0012 D82 requires the dashboard to surface staleness; reviewing that during P5-2 implementation.
+
+**Neutral.**
+
+- The protocol is portable. Future provider plugins adopting direct-API probes (mistral if its `/v1/usage` exists) can reuse the same six rules with provider-specific endpoint substitution.
+
+---
+
+## Alternatives considered
+
+### A — Probe lives in `server.mjs` (OCP-style)
+
+OCP's probe is in `server.mjs:842-1109` because OCP is single-provider and pre-plugin-architecture. Porting that pattern to OLP would violate ADR 0002 (per-provider knowledge stays in `lib/providers/`). Rejected.
+
+### B — Spawn `claude -p --dry-run` and parse ratelimit headers
+
+`claude -p` does not expose response headers; the CLI consumes and discards them. Even if it did, parsing CLI stdout is fragile. Rejected.
+
+### C — Wait for Anthropic to publish a public quota API
+
+The 2026-06-15 Agent SDK Credit billing-split announcement does not include a public quota API. Anthropic may publish one in the future; this ADR is forward-compatible (Rule 7 explicitly notes "if Anthropic publishes a public ratelimit API, this entire workaround becomes obsolete — re-evaluate"). Rejected for v0.5.0 (no ETA).
+
+### D — Mandate token-rotation in OLP
+
+Tempting (auditability), but OCP's experience shows token rotation breaks the spawn path more often than it improves security at family-scale deployment. The credential rotation cadence is Anthropic-side (token TTL); OLP respects whatever Claude Code does. Rejected.
+
+---
+
+## Authority + cross-references
+
+- **ADR 0002 Amendment 8** — the contract-level permission. ADR 0013 is the implementation discipline for that permission.
+- **ADR 0012** — Phase 5 charter that schedules D80 implementation.
+- **ADR 0011** — anonymous-key deployment-context (LAN-only). Separate scope; this ADR does not amend it.
+- **`~/.cc-rules/memory/learnings/anthropic_plan_usage_probe_schema_2026_05_26.md`** — the live schema pin. Updated on every drift event per Rule 5.
+- **`alignment.yml`** — must continue to blacklist `/api/oauth/usage` and related hallucinated tokens. Must NOT add `/v1/messages` to the blacklist (legitimate endpoint).
+- **OCP `server.mjs:842-1109`** — the source-of-truth port reference for D80.
+- **OCP `ALIGNMENT.md`** — the institutional precedent (2026-04-11 drift → ALIGNMENT introduction) this ADR consolidates for OLP.

+# OLP IDE & client integrations
+
+This directory documents per-tool setup for the IDEs and AI clients OLP
+supports. Every page follows the same shape: one-line description, status
+icon, copy-paste-able config block, known issues, OLP-specific notes, and a
+one-line verification command.
+
+## Index
+
+| Tool | Status | Path | Notes |
+|---|---|---|---|
+| [Continue.dev](./continue.md) | ✅ Supported | VS Code / JetBrains extension | `config.yaml` (NOT `config.json`); supports custom headers |
+| [Cline](./cline.md) | ✅ Supported | VS Code extension | OpenAI-compatible provider; UI field occasionally vanishes (Cline #7128) |
+| [Cursor](./cursor.md) | ⚠️ Best-effort | Cursor editor | "Override OpenAI Base URL" — known fragile across releases |
+| [Aider](./aider.md) | ✅ Supported | terminal CLI | `OPENAI_API_BASE` env + `openai/` model prefix |
+| [Claude Code](./claude-code.md) | ❌ Not supported | terminal CLI | Anthropic wire format only; OLP serves OpenAI wire format. Use Cline instead. |
+| [OpenClaw](./openclaw.md) | ✅ Supported | Telegram + Discord gateway | `/olp` slash command via the [`olp-plugin/`](../../olp-plugin/) plugin |
+
+## Status legend
+
+- ✅ **Supported** — works against OLP's OpenAI-compatible `/v1/chat/completions`
+  endpoint; the tool's IR fields flow through OLP's IR without lossy translation
+  warnings on the documented chain.
+- ⚠️ **Best-effort** — works in current versions but the tool has known
+  upstream bugs around base-URL configuration; expect occasional weirdness.
+- ❌ **Not supported** — the tool's wire protocol or transport is incompatible
+  with what OLP serves; recommended alternative is documented on the page.
+
+## How OLP's response headers help debugging
+
+Every response carries (see [README § Response Headers](../../README.md#response-headers)):
+
+- `X-OLP-Provider-Used` — which provider's plugin served the request
+- `X-OLP-Model-Used` — which model the served provider used
+- `X-OLP-Fallback-Hops` — `0` = primary chain entry served it
+- `X-OLP-Cache` — `hit | miss | bypass`
+- `X-OLP-Latency-Ms` — end-to-end latency at the proxy
+
+When something looks wrong in an IDE, the first sanity check is `curl -i`
+against `/v1/chat/completions` with the same key — those headers tell you
+whether the IDE config is broken or OLP routed somewhere unexpected.
+
+## Cross-references

+# Aider + OLP
+
+[Aider](https://aider.chat) is a terminal-native pair programmer that
+edits files in your local git repo and commits each change. It speaks
+OpenAI's `/v1/chat/completions` wire format via the `openai/` model
+prefix.
+
+**Status:** ✅ Supported.
+
+**Tested against:** Aider v0.6x. Aider's OpenAI integration has been stable
+across many releases — this is the most reliable IDE/CLI binding to OLP.
+
+## Quick setup
+
+Three knobs, all environment variables or `.env`:
+
+```bash
+# Required: point Aider at OLP's chat-completions endpoint
+export OPENAI_API_BASE=http://127.0.0.1:4567/v1
+
+# Required: OLP plaintext token
+export OPENAI_API_KEY=olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+
+# Then invoke Aider with an OLP-routable model, prefixed `openai/`:
+aider --model openai/claude-sonnet-4-5
+```
+
+The `openai/` prefix tells Aider to use its OpenAI-compatible adapter for
+the named model. Aider's litellm layer parses this and sends the request
+to whatever `OPENAI_API_BASE` resolves to.
+
+Replace the API key with the plaintext token printed by `olp-keys keygen
+--name=aider`. Family members on the LAN should substitute the OLP host's
+IP for `127.0.0.1` (or use `olp-connect <ip>`).
+
+## Aider's `.env` support
+
+Aider auto-loads a `.env` file from the current directory or the git repo
+root. The accepted keys are:
+
+```bash
+# .env at the project root
+OPENAI_API_BASE=http://127.0.0.1:4567/v1
+OPENAI_API_KEY=olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+
+# Optional: Aider's own AIDER_-prefixed equivalents work too
+AIDER_OPENAI_API_BASE=http://127.0.0.1:4567/v1
+```
+
+The `AIDER_` prefix wins over the bare prefix when both are set. Pick one;
+mixing them invites surprises during debugging.
+
+**Hygiene:** add `.env` to `.gitignore` if your repo doesn't already. The
+OLP token is plaintext-recoverable from disk only because the chat surface
+explicitly opts into it (see [ADR 0011](../adr/0011-anonymous-key-deployment-context.md))
+— do not let your IDE bind unintentionally.
+
+## Known issues
+
+- **No custom-headers support.** Aider does not expose a way to set extra
+  HTTP headers on outgoing requests. OLP's optional `X-OLP-Chain` /
+  `X-OLP-Bypass-Cache` headers are therefore not available via Aider —
+  routing is determined by the model name alone.
+
+- **`/v1` trailing matters.** `OPENAI_API_BASE` must end at `/v1` (without
+  `/chat/completions`); Aider appends the remainder. Setting it to the bare
+  host or with a trailing `/chat/completions` causes 404s.
+
+- **Aider sends `max_tokens` by default.** OLP forwards `max_tokens` to
+  every provider. If you see "model X does not support max_tokens" errors,
+  the underlying provider rejects it — check `X-OLP-Provider-Used` and
+  filter that provider out of the chain for the affected model.
+
+## OLP-specific notes
+
+Aider's request shape is faithful to OpenAI's `/v1/chat/completions`
+spec — `messages`, `model`, `max_tokens`, `stream`, `temperature`,
+`tools`. All map cleanly into OLP's IR with no lossy-translation warnings.
+
+For long-context work (codebase summaries, large diffs), set
+`streaming.heartbeat_interval_ms: 15000` in `~/.olp/config.json` (see
+[README § Environment Variables](../../README.md#configjson-keys-introduced-at-phase-4))
+so the SSE stream stays alive through reverse proxies during silent
+windows.
+
+## Test it
+
+```bash
+# In a scratch dir:
+aider --model openai/claude-haiku-4-5 --no-stream --message "say ok"
+```
+
+Then check OLP's audit log:
+
+```bash
+npx olp logs 5
+```
+
+The most recent entry should show `provider: anthropic` (or whatever
+provider haiku routes to in your chain) and `cache_status: miss`.

+# Claude Code + OLP
+
+[Claude Code](https://docs.anthropic.com/en/docs/claude-code/overview) is
+Anthropic's official terminal-native agent. It speaks the Anthropic
+`/v1/messages` wire format and cannot be configured to use an
+OpenAI-compatible chat-completions endpoint.
+
+**Status:** ❌ Not supported.
+
+## Why
+
+OLP serves only the OpenAI `/v1/chat/completions` wire format. Adding
+`/v1/messages` (the Anthropic shape) was explicitly considered for
+Phase 4 and rejected, per
+[ADR 0010 § Out of Phase 4 scope](../adr/0010-phase-4-charter-operator-and-client-ux.md).
+
+The short version of the rationale:
+
+- **No billing benefit.** After Anthropic's 2026-06-15 split, `claude -p` /
+  Agent SDK / third-party agent traffic moves out of the Pro/Max
+  subscription pool and into a separate paid Agent SDK Credit pool. OLP's
+  fallback discipline ("when one provider's quota runs out, try the next")
+  does not save money for this traffic — it just routes the same paid
+  request to a different paid backend. The subscription leverage that
+  makes OLP valuable for OpenAI-shape traffic does not exist for
+  Anthropic-shape traffic.
+
+- **Degrades worse on fallback.** When OLP's primary chain entry (Anthropic)
+  is exhausted, the fallback hop is typically OpenAI Codex or Mistral Vibe.
+  Those providers speak OpenAI tool-calling schema; OLP would have to
+  translate Anthropic's `/v1/messages` tool shape into OpenAI tool shape on
+  every fallback. That translation is lossy and is what ADR 0010 calls out
+  as "net non-positive under P0 failure".
+
+- **Same outcome reachable via the recommended alternative.** Cline, Cursor,
+  Aider, and Continue.dev all speak OpenAI's wire format and have parity
+  with Claude Code on the "AI edits files in my repo" use case. OLP serves
+  them today.
+
+## What to use instead
+
+**Recommended:** [Cline](./cline.md). It's an in-IDE autonomous coder that
+operates on the same loop Claude Code does (read files, propose edits,
+run tools, iterate). The "OpenAI Compatible" provider points cleanly at
+OLP's `/v1/chat/completions` endpoint. You get OLP's full fallback chain
+(Anthropic → OpenAI Codex → Mistral) instead of being pinned to one
+provider.
+
+For terminal users specifically:
+
+- **[Aider](./aider.md)** if you want the Claude-Code-style git-aware
+  pair programmer in the terminal.
+- **OpenClaw** if you want Telegram/Discord-driven access to the
+  fallback chain (see [`openclaw.md`](./openclaw.md)).
+
+## Re-open trigger
+
+ADR 0010 documents the conditions under which OLP would reconsider
+`/v1/messages`:
+
+> (a) ADR 0009 P0 confirms interactive-mode billing classification as
+> subscription (≥ 2026-07-15) AND (b) maintainer explicitly opens
+> Phase 5 "Anthropic-shape hub" scope with the name of at least one
+> family member who wants CC access.
+
+Until both conditions fire, OLP intentionally does not implement
+`/v1/messages`. The decision is recorded in ADR 0010 § "Out of Phase 4
+scope" and ADR 0009 (Anthropic interactive-mode path placeholder).
+
+## If you absolutely must use Claude Code
+
+Point Claude Code at api.anthropic.com directly. OLP cannot proxy that
+traffic. You will:
+
+- Burn against the Anthropic Pro/Max OAuth subscription (pre-2026-06-15) or
+  the Agent SDK Credit pool (≥ 2026-06-15).
+- Lose every fallback property OLP provides — when Anthropic's quota is
+  exhausted, Claude Code stops working until the quota resets.
+- Lose OLP's response headers (`X-OLP-Provider-Used` etc.), audit log
+  entries, cache hits, and `/health` visibility.
+
+This is documented here only so the trade-off is explicit, not as a
+recommendation.

+# Cline + OLP
+
+[Cline](https://github.com/cline/cline) is an autonomous-coder VS Code
+extension. It speaks OpenAI's `/v1/chat/completions` wire format via its
+"OpenAI Compatible" provider option.
+
+**Status:** ✅ Supported.
+
+**Tested against:** Cline v3.x (extension version visible in VS Code's
+extension panel). Cline's settings UI has shipped multiple variants of the
+base-URL field across 2025-2026; if your version doesn't show the field
+described below, see the Known Issues section.
+
+## Quick setup
+
+1. Open the Cline panel in VS Code (sidebar icon).
+2. Click the settings gear → "API Provider".
+3. Select **OpenAI Compatible**.
+4. Fill the fields:
+
+   | Field | Value |
+   |---|---|
+   | Base URL | `http://127.0.0.1:4567/v1` |
+   | API Key | `olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX` |
+   | Model ID | `claude-sonnet-4-5` |
+
+5. Save. Cline shows the model name in the bottom-right corner of the panel.
+
+Replace the API key with the plaintext token printed by `olp-keys keygen
+--name=cline`. Family members on the LAN should substitute the OLP host's
+IP for `127.0.0.1` (or use `olp-connect <ip>`).
+
+## Known issues
+
+- **Cline issue [#7128](https://github.com/cline/cline/issues/7128) —
+  base-URL UI field intermittently disappears.** Several Cline releases in
+  2025-2026 shipped a settings UI where the "Base URL" field is hidden when
+  the "OpenAI Compatible" provider is freshly selected. Workaround: switch
+  to a different provider, save, switch back to "OpenAI Compatible" — the
+  field returns. Verify the field is visible in your version BEFORE
+  troubleshooting OLP itself.
+
+- **Cline writes settings to `.vscode/settings.json` under a
+  `cline.apiConfiguration` key (workspace-scoped) and to the VS Code global
+  state (machine-scoped) depending on the "save to workspace" toggle.** If
+  Cline keeps "forgetting" the OLP base URL across VS Code restarts, the
+  workspace state is overriding the global state. Either save to workspace
+  explicitly, or clear the workspace key and use global state.
+
+- **Cline sometimes lowercases the model ID before sending.** OLP's
+  `models-registry.json` uses canonical case (e.g. `claude-sonnet-4-5`).
+  This is fine — OLP's router lowercases the requested model for chain
+  lookup. But if you see `unknown model` errors, double-check the exact
+  string Cline sent via the OLP response headers (curl test below).
+
+## OLP-specific notes
+
+Cline does not expose a custom-headers field in its OpenAI Compatible
+provider UI as of v3.x. The OLP routing chain is selected purely from the
+model ID — pick the canonical name (e.g. `claude-sonnet-4-5`) that matches
+a `routing.chains` key in your `~/.olp/config.json`.
+
+OLP's response headers (`X-OLP-Provider-Used`, `X-OLP-Cache`,
+`X-OLP-Latency-Ms`) are not visible in Cline's UI but are captured by VS
+Code's Developer Tools Network panel when Cline runs the request.
+
+## Test it
+
+```bash
+# 1. Verify OLP accepts Cline-shape requests
+curl -sI -X POST http://127.0.0.1:4567/v1/chat/completions \
+  -H "Authorization: Bearer olp_XXXXXX" \
+  -H "Content-Type: application/json" \
+  -d '{"model":"claude-sonnet-4-5","messages":[{"role":"user","content":"ok"}],"max_tokens":5,"stream":false}' \
+  | grep -i x-olp
+```
+
+Expect `X-OLP-Provider-Used: anthropic` (or whichever provider serves
+sonnet in your chain) and `X-OLP-Cache: miss` on first request.
+
+## Why not /v1/messages?
+
+Cline supports Anthropic-shape requests via a separate "Anthropic" provider
+in its UI. OLP does not implement `/v1/messages`. Use Cline's **OpenAI
+Compatible** option pointed at OLP rather than Cline's **Anthropic** option
+pointed at api.anthropic.com — the OLP chain gives you fallback to OpenAI
+Codex / Mistral / etc. when the Anthropic subscription hits its quota
+ceiling. See [ADR 0010 § /v1/messages defer rationale](../adr/0010-phase-4-charter-operator-and-client-ux.md).

+# Continue.dev + OLP
+
+[Continue.dev](https://continue.dev) is an open-source autocomplete +
+chat extension for VS Code and JetBrains IDEs. It speaks OpenAI's
+`/v1/chat/completions` wire format, so it works against OLP with no
+shim layer.
+
+**Status:** ✅ Supported.
+
+**Tested against:** Continue.dev v0.10.x (`config.yaml` schema). The
+older `config.json` schema (≤ v0.8) is **not** documented here — Continue
+deprecated it in late 2025 and emits a one-shot migration warning.
+
+## Quick setup
+
+Edit `~/.continue/config.yaml` (or open the Continue config from the IDE's
+extension panel and paste this in):
+
+```yaml
+models:
+  - name: olp-chat
+    provider: openai
+    model: claude-sonnet-4-5
+    apiBase: http://127.0.0.1:4567/v1
+    apiKey: olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+    roles:
+      - chat
+    requestOptions:
+      headers:
+        # Optional: pin which routing chain key applies. If omitted, OLP
+        # looks up the chain via the model name above.
+        X-OLP-Chain: claude-sonnet-4-5
+  - name: olp-autocomplete
+    provider: openai
+    model: claude-haiku-4-5
+    apiBase: http://127.0.0.1:4567/v1
+    apiKey: olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+    roles:
+      - autocomplete
+```
+
+Replace the API key with the plaintext token printed by `olp-keys keygen
+--name=continue-dev`. Family members on the LAN should substitute the OLP
+host's IP for `127.0.0.1` (or use `olp-connect <ip>` to do this for them
+automatically).
+
+## Known issues
+
+- **`apiBase`, NOT `baseURL`.** Continue's YAML schema uses `apiBase` (no
+  `URL` casing). The older `config.json` `baseURL` key was renamed during the
+  v0.10 schema cut. If you copy a snippet from a 2024 blog post and it
+  silently routes to api.openai.com, this is why.
+- **Trailing `/v1` matters.** OLP's chat-completions endpoint is at
+  `/v1/chat/completions`; Continue appends `/chat/completions` to whatever
+  `apiBase` resolves to. Set `apiBase: http://host:4567/v1` (with `/v1`),
+  not the bare host.
+- **Provider stays `openai`.** Continue's `provider: anthropic` would send
+  Anthropic-shape requests to `/v1/messages`, which OLP does not implement
+  (see [`claude-code.md`](./claude-code.md) for the rationale).
+
+## OLP-specific notes
+
+Continue's `requestOptions.headers` lets you pin OLP-specific routing
+behaviour without altering the model name itself. Useful headers:
+
+- `X-OLP-Chain: <chain-key>` — explicitly select the routing chain.
+- `X-OLP-Bypass-Cache: true` — force a fresh spawn for the next request
+  (debugging cache-poisoning suspicions).
+
+OLP's response headers (`X-OLP-Provider-Used`, `X-OLP-Cache`, etc.) are
+visible via VS Code's `Developer: Toggle Developer Tools` → Network panel
+when Continue runs the request.
+
+## Test it
+
+After config save, open the Continue chat panel and send a one-word
+message ("ok"). Then on the terminal:
+
+```bash
+curl -sI -X POST http://127.0.0.1:4567/v1/chat/completions \
+  -H "Authorization: Bearer olp_XXXXXX" \
+  -H "Content-Type: application/json" \
+  -d '{"model":"claude-haiku-4-5","messages":[{"role":"user","content":"ok"}],"max_tokens":5}' \
+  | grep -i x-olp
+```
+
+Expect `X-OLP-Provider-Used: anthropic` (or whichever provider your chain
+routes haiku to) and `X-OLP-Cache: miss` on first request, `hit` on the
+second.

+# Cursor + OLP
+
+[Cursor](https://cursor.com) is an AI-first VS Code fork. It has an
+"Override OpenAI Base URL" setting that, when populated, routes its
+default-model traffic to your URL using the OpenAI wire format.
+
+**Status:** ⚠️ Best-effort.
+
+**Reason:** Cursor's base-URL override is known to be fragile across
+releases. Multiple 2025-2026 forum threads document the setting silently
+reverting, model-list dropdowns not populating from the override URL, and
+streaming responses falling back to the default backend on parse errors.
+The behaviour is not specific to OLP — every OpenAI-compatible proxy
+maintainer documents the same caveats — but Cursor's release cadence is
+faster than most third-party proxies can test against.
+
+## Quick setup
+
+1. Open Cursor → Settings → "Models" → enable **OpenAI API Key**.
+2. Paste your OLP plaintext token into the **API Key** field.
+3. Click "Override OpenAI Base URL" and paste:
+
+   ```
+   http://127.0.0.1:4567/v1
+   ```
+
+4. Click "Verify". Cursor sends a probe; on success the indicator turns
+   green.
+
+5. **Crucial step:** in the model list, disable every model that is NOT
+   in your `~/.olp/config.json` `routing.chains`. Cursor's chat will round-
+   robin across enabled models and any model OLP can't route will error.
+
+Replace the API key with the plaintext token printed by `olp-keys keygen
+--name=cursor`. Family members on the LAN should substitute the OLP host's
+IP for `127.0.0.1` (or use `olp-connect <ip>`).
+
+## Known issues
+
+- **Override URL silently reverts on Cursor update.** Two reported variants:
+  (a) the field empties; (b) the field shows the OLP URL but Cursor still
+  hits api.openai.com under the hood. Workaround: after every Cursor
+  update, re-open settings, click "Verify" again, and check the OLP
+  server's `/health` for incoming probe requests.
+
+- **Model-list dropdown does not populate from the override URL.** Cursor
+  hardcodes its model list rather than reading `GET /v1/models`. This is
+  why step 5 above is required — there is no way to make Cursor "discover"
+  your models. You have to disable each model individually that OLP can't
+  serve.
+
+- **Streaming response parsing is stricter than OpenAI's actual SSE spec.**
+  Cursor occasionally falls back to the default backend if the SSE stream
+  contains a slightly malformed chunk (e.g. an empty `data:` line that
+  OpenAI's API does emit but Cursor's parser doesn't expect). OLP's SSE
+  emitter follows the spec; this is on Cursor's side. If you see traffic
+  hitting api.openai.com despite the override, this is the most likely
+  cause.
+
+- **Cursor's "Tab" autocomplete is NOT covered by the override.** Tab
+  completion uses a Cursor-proprietary endpoint that is not affected by the
+  OpenAI base URL setting. Only the chat panel is. This is documented
+  Cursor behaviour and is not a bug.
+
+## OLP-specific notes
+
+Cursor sends `model: "gpt-4"` or `model: "gpt-3.5-turbo"` (legacy aliases)
+unless you explicitly select another from its dropdown. Add aliases to
+your `~/.olp/config.json` `routing.chains` so these route somewhere sane:
+
+```json
+{
+  "routing": {
+    "chains": {
+      "gpt-4":         [ { "provider": "openai", "model": "gpt-5" } ],
+      "gpt-3.5-turbo": [ { "provider": "openai", "model": "gpt-5-mini" } ]
+    }
+  }
+}
+```
+
+(Substitute the OpenAI Codex model names listed by `olp models`.)
+
+## Recommendation
+
+**Do not engineer workarounds for Cursor-side bugs.** Cursor's release
+cadence will fix or re-break the override URL handling at unpredictable
+intervals. If your daily-driver flow is unreliable, switch to Cline (see
+[`cline.md`](./cline.md)) — it has a stable OpenAI-compatible provider
+that does not break across releases.
+
+## Test it
+
+```bash
+curl -sI -X POST http://127.0.0.1:4567/v1/chat/completions \
+  -H "Authorization: Bearer olp_XXXXXX" \
+  -H "Content-Type: application/json" \
+  -d '{"model":"gpt-4","messages":[{"role":"user","content":"ok"}],"max_tokens":5}' \
+  | grep -i x-olp
+```
+
+After hitting "Send" in Cursor's chat, check the OLP server's recent
+requests via:
+
+```bash
+npx olp logs 10
+```
+
+If you don't see Cursor's request in the audit log, traffic isn't reaching
+OLP — re-check the override URL.
+
+## Cross-references
+
+- Cursor forum threads on base-URL fragility: https://forum.cursor.com/ (search "OpenAI base URL")
+- [`olp-connect`](../../bin/olp-connect) writes Cursor's `cursorrc` if
+  detected, but cannot guarantee the override survives a Cursor update.

+# OpenClaw + OLP
+
+[OpenClaw](https://github.com/openclaw/openclaw) is a multi-bot gateway
+that exposes slash commands on Telegram, Discord, and other chat
+surfaces. OLP ships [`olp-plugin/`](../../olp-plugin/) as a native
+OpenClaw plugin that registers a `/olp` slash command with read-only
+parity to the local `olp` CLI.
+
+**Status:** ✅ Supported.
+
+## What you get
+
+After install, from Telegram or Discord:
+
+| Slash command | Maps to | Tier |
+|---|---|---|
+| `/olp status` | GET `/v0/management/status` | owner |
+| `/olp health` | GET `/health` | public |
+| `/olp usage` | GET `/v0/management/dashboard-data` | owner |
+| `/olp models` | GET `/v1/models` | public |
+| `/olp cache` | GET `/cache/stats` | owner |
+| `/olp providers` | local registry view | public |
+| `/olp chain show [model]` | local chain view | public |
+| `/olp doctor` | informational (HTTP endpoint not yet shipped) | — |
+| `/olp help` | usage text | — |
+
+**Mutating subcommands are deliberately not exposed via chat.** `keygen`,
+`revoke`, `restart`, `logs` are SSH-only. See
+[`olp-plugin/README.md`](../../olp-plugin/README.md#what-you-can-not-do-from-chat-by-design)
+for the rationale.
+
+## Quick setup
+
+### 1. Install the plugin
+
+Two install paths — either works.
+
+**Option A — OpenClaw CLI:**
+
+```bash
+openclaw plugins install /path/to/olp/olp-plugin/
+```
+
+**Option B — symlink:**
+
+```bash
+mkdir -p ~/.openclaw/extensions/
+ln -s /path/to/olp/olp-plugin/ ~/.openclaw/extensions/olp
+```
+
+### 2. Mint a bot owner key
+
+Run on the OLP host (NOT in chat):
+
+```bash
+npx olp-keys keygen --owner --name=openclaw-bot
+```
+
+Capture the printed plaintext token — it is shown exactly once.
+
+### 3. Configure
+
+Edit `~/.openclaw/openclaw.json`:
+
+```json
+{
+  "plugins": {
+    "olp": {
+      "proxyUrl": "http://127.0.0.1:4567",
+      "apiKey": "olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+    }
+  }
+}
+```
+
+### 4. Restart the gateway
+
+```bash
+openclaw gateway restart
+```
+
+The plugin is now active. Try `/olp help` in your bot's chat.
+
+## Known issues
+
+- **`openclaw gateway restart` is required after install.** OpenClaw caches
+  plugin discovery at gateway start. `openclaw plugins reload` does not
+  guarantee a fresh import of the plugin module.
+
+- **Owner key revocation kicks the plugin out immediately.** If you revoke
+  the bot's owner key (`npx olp-keys revoke --id=<id>`), the next `/olp
+  status` will return `401 unauthorized`. Mint a replacement key with a
+  new name and edit `~/.openclaw/openclaw.json`; do NOT reuse the revoked
+  key's UUID.
+
+- **Long responses are truncated.** Telegram caps messages at ~4096
+  characters. The plugin truncates with a `... [truncated, use SSH for
+  full]` suffix when the rendered output would exceed ~3900 chars. Use
+  SSH + the local `olp` CLI for full output.
+
+## OLP-specific notes
+
+The plugin honours these env vars on the OpenClaw gateway process:
+
+- `OLP_PROXY_URL` — full URL, overrides plugin config `proxyUrl`.
+- `OLP_PORT` — port only, localhost assumed; overrides `proxyUrl` when
+  `OLP_PROXY_URL` is unset.
+
+If you run the OpenClaw gateway under launchd or systemd with custom env
+vars, set `OLP_PROXY_URL` there rather than editing the plugin config —
+that way the same plugin install can serve multiple OLP hosts.
+
+## Per-bot vs maintainer key
+
+**Always create a dedicated bot key**, never the maintainer's personal
+owner key. The bot key:
+
+- Has its own `id` so you can revoke it without affecting other clients.
+- Has its own audit-log entries so you can attribute `/v0/management/*`
+  traffic to the bot.
+- Can be rotated routinely (every 90 days etc.) without coordinating with
+  the maintainer's daily-driver IDE configs.
+
+## Test it
+
+After restart, in Telegram or Discord:
+
+```
+/olp health
+/olp status
+/olp models
+```
+
+Each should return a code-block-wrapped response within a few seconds.
+
+If you see `401 unauthorized`: the configured key is missing / wrong /
+revoked. If you see `403 forbidden`: the key is not owner-tier. If you
+see `OLP error: fetch failed` or similar: the `proxyUrl` is unreachable
+from the gateway host (test with `curl http://<proxyUrl>/health` from
+that host).

 - **What.** Currently the streaming branch does NOT participate in D16 salvage (the salvage-on-SPAWN_FAILED + chunks pattern that the buffered path uses). Streaming SPAWN_FAILED mid-stream → the truncation marker (D35 #10) fires, but no salvage logic captures partial chunks for downstream cache reuse.
 - **Why deferred.** Less impactful than #1 — at most one client benefits per spawn event, and the buffered path already provides salvage for the bulk of requests. Streaming is the minority path.
-- **Design ADR.** Not yet ratified. Coordinated with #1 because the tee architecture changes the salvage semantics (multiple clients may want different finish_reason interpretations on source-mid-stream-failure).
+- **Status update post-#1 close (2026-05-25).** #1 was originally bundled with #6 in the design ADR (Amendment 8). The tee architecture as implemented does NOT carry salvage semantics — D57's tee writes `accumulatedChunks` to cache only on normal source completion (stop chunk seen); on SPAWN_FAILED mid-stream the cache layer rejects all clients with the error and does NOT persist partial chunks. D58 preserves D16's truncated-not-cached invariant via server-layer `cacheStore.delete` on stop-less exhaustion. #6 therefore remains independently deferrable.
+- **Design ADR.** Not yet ratified. The unbundling from #1 means #6 now needs its own ADR amendment when triggered.
 - **Tracking.** Not a GitHub issue. Tracked here.

+## #8 — Dashboard enrichment: per-provider subscription quota + reset times + 1-min refresh + manual refresh (D78 follow-up) — ✅ **CLOSED (D82, v0.5.0)**
+
+- **Status.** Closed at D82 (Phase 5). `dashboard.html` restructured to Claude.ai-style per-provider rows rendering `quota_v2`. Closed by PR on branch `d82-dashboard-ui-claude-ai-style`; ships with v0.5.0. 60s quota auto-refresh + manual refresh button + visibilityState guard implemented. Graceful fallback to legacy `quota` field when server runs a pre-D81 build.
+- **What.** Phase 3 dashboard (D51 `dashboard.html`, v0.3.0) shows: per-provider quota (currently always "n/a — no quota api"), last-24h request count + cache hit + fallback rate, 30d request-count sparkline, top fallback chains. **Maintainer request 2026-05-26 post-D78**: extend to show what each enabled provider's subscription is actually consuming, with reset times visible, refresh once per minute (current 30s is OK but maintainer specified 1min target), and a manual refresh button. Reference design: Claude.ai's own `claude.ai/settings/usage` page — current session bar with "Resets in 1hr 6min", weekly all-models bar with "Resets Sun 9:00 PM", per-model bar (Sonnet only), additional features (routine runs), usage credits + monthly spend limit + auto-reload toggle.
+- **Why deferred.** v0.3.0/v0.4.x ships the dashboard frame but `provider.quotaStatus()` returns `null` in all three v0.1 plugins (anthropic / openai / mistral). The ratifying spec in ADR 0004 Amendment 2 punts `quotaStatus()` to v1.x ("soft trigger reactivation") — this dashboard ask is the **operator-facing reason** that work would land.
+- **What this requires.** Per-provider plugin work + dashboard.html UI work + audit-query.mjs aggregation:
+  1. **`lib/providers/anthropic.mjs quotaStatus()`** — discover where the maintainer's Claude.ai subscription quota state is exposed. Candidates: (a) `claude` CLI command (e.g., `claude usage`) if Anthropic adds one — currently absent; (b) parsing the `claude-code` output for rate-limit error messages and caching state from headers; (c) hitting `api.anthropic.com/v1/.../usage` directly via the OAuth refresh token — not a documented endpoint, primary-source risk. ADR 0002 Rule 1 / Rule 5 require an authority citation before any implementation. Likely path: **wait until Anthropic publishes a documented endpoint**, OR derive from audit-side request counts only (no real quota truth, just "you sent N requests in the current 5h window").
+  2. **`lib/providers/openai.mjs quotaStatus()`** — codex CLI doesn't expose ChatGPT-subscription quota state. OpenAI rate-limit headers per request might be parseable but ADR 0004 Amendment 2 explicitly says no plugin parses HTTP status at v0.1.
+  3. **`lib/providers/mistral.mjs quotaStatus()`** — Le Chat Pro has `/v1/usage` endpoint per Mistral docs (verify).
+  4. **`dashboard.html` UI restructure** to a Claude.ai-style layout: rows of (label, bar, "Resets in X" / "Resets at <day-of-week> <time>", percent). Add a manual refresh button + change auto-poll from 30s → 60s. Optionally a usage-credits / per-key spend display if Phase 5 ships per-key cost weights.
+  5. **`lib/audit-query.mjs`** — extend `aggregateRequests` / `spendTrendDaily` to compute "in the current rolling window" (since session/week start) per provider. Today's aggregates are wall-clock windows; subscription resets are per-account-anchored. Need a way to model session windows (e.g., "Anthropic 5h-from-first-request-since-last-reset").
+- **Reference (maintainer 2026-05-26).** Screenshot of `claude.ai/settings/usage` shared inline. Key panels: Plan usage limits (current session + resets-in), Weekly limits (All models / Sonnet only / per-feature breakdown, each with resets-on), Additional features (Daily included routine runs N / 15), Usage credits (toggle + spent vs monthly limit + auto-reload + buy-credits link).
+- **Tracking.** Not yet a GitHub issue. Track here + cross-reference ADR 0004 Amendment 2 (soft trigger reactivation — same `quotaStatus()` data-source work) when this becomes Phase 5 scope.
+- **Code anchors today.**
+  - `dashboard.html` — current 4 panels; needs restructure to Claude.ai-style row layout
+  - `lib/providers/anthropic.mjs` / `openai.mjs` / `mistral.mjs` — `quotaStatus()` returns null today
+  - `lib/audit-query.mjs` — current `aggregateRequests` is wall-clock-window; needs session-window variant
+- **Trigger to start.** ANY of: (a) Anthropic publishes a documented `claude usage` CLI or `api.anthropic.com/v1/usage` endpoint, (b) maintainer hits real "I want to see quota right now" pain often enough to design without per-provider truth (audit-derived only), (c) Phase 5 multi-tenant adds per-key spend limits and the dashboard needs to surface those.

+ * lib/doctor.mjs — OLP doctor framework (Phase 4 / D65)
+ *
+ * Authority: ADR 0010 § Phase 4 D64-D67 + ADR 0002 Amendment 7 (D67) —
+ *   per-provider `doctorChecks()` contract method that this framework consumes.
+ *
+ * `olp doctor` runs a set of `Check` objects. Each check has:
+ *   - id: string                     (unique, e.g. 'server.running', 'anthropic.cli_available')
+ *   - category: 'server'|'auth'|'config'|'provider'|'system'
+ *   - async run(): { status: 'ok'|'fail'|'warn', message, evidence? }
+ *
+ * Built-in checks (categories server / auth / config / system) are defined in
+ * `buildBuiltinChecks()` below; per-provider checks are sourced from each loaded
+ * plugin's optional `doctorChecks()` method (ADR 0002 Amendment 7).
+ *
+ * Output shape (machine-readable — consumed by `bin/olp.mjs --json`):
+ *   {
+ *     schema_version: 1,
+ *     generated_at: '2026-05-26T...',
+ *     checks: [{ id, category, status, message, evidence? }],
+ *     fail_count: number,
+ *     warn_count: number,
+ *     kind: 'noop'|'fix_server'|'fix_oauth'|'fix_config'|'fix_provider'|'fresh_install',
+ *     next_action: { ai_executable: string[], human_required: string[], verify: string },
+ *     summary: string,
+ *   }
+ *
+ * `kind` precedence (highest first — the most upstream blocker wins):
+ *   1. fresh_install      — config.exists FAIL (~/.olp/config.json missing/malformed)
+ *   2. fix_server         — server.running FAIL
+ *   3. fix_oauth          — auth.owner_key_exists FAIL
+ *   4. fix_provider       — any provider-category FAIL
+ *   5. fix_config         — any other config-category FAIL
+ *   6. noop               — all OK (or WARN-only)
+ *
+ * `next_action.ai_executable[]` aggregates `evidence.fix_commands[]` from every
+ * FAIL check; `next_action.human_required[]` aggregates `evidence.human_steps[]`.
+ * `verify` is always `olp doctor` (re-run after applying the fix).
+ *
+ * Design notes:
+ *   - Pure functions + dependency injection: callers pass `{ checks }` (which can
+ *     be overridden for tests) plus a `{ now }` clock for deterministic timestamps.
+ *   - No filesystem writes. No process.exit. No console.log. Callers handle I/O.
+ *   - All checks run in parallel via Promise.all — individual check failures are
+ *     captured (not propagated) so one broken check does not hide others.

+# olp-plugin
+
+OpenClaw gateway plugin that exposes a `/olp` slash command on Telegram and
+Discord, with subcommand parity to the local `olp` CLI (`bin/olp.mjs`) minus
+mutating operations.
+
+**Authority:** [ADR 0010 § Phase 4 D71-D73](../docs/adr/0010-phase-4-charter-operator-and-client-ux.md).
+
+## Status
+
+✅ Shipped at v0.4.0 (read-only subset of `olp` CLI).
+
+## What you can do from chat
+
+| Slash command | Maps to | Tier |
+|---|---|---|
+| `/olp status` | GET `/v0/management/status` | owner |
+| `/olp health` | GET `/health` | public |
+| `/olp usage` | GET `/v0/management/dashboard-data` | owner |
+| `/olp models` | GET `/v1/models` | public |
+| `/olp cache` | GET `/cache/stats` | owner |
+| `/olp providers` | local registry view | public |
+| `/olp chain show [model]` | local chain view (empty unless wired) | public |
+| `/olp doctor` | informational only (HTTP doctor endpoint not yet shipped) | — |
+| `/olp help` | usage text | — |
+
+## What you can NOT do from chat (by design)
+
+The following `olp` CLI subcommands are **deliberately not** ported to the
+chat surface, because Telegram + Discord are shared / persistent message
+streams and key material or raw audit logs should not be flowing across
+them:
+
+- `olp keys keygen` — key material would land in chat history
+- `olp keys revoke` — accidental misclick could lock out clients
+- `olp restart` — a misclick should not cycle the proxy
+- `olp logs` — audit content may carry PII
+
+Use SSH to the host running OLP and the local `olp` CLI for those.
+
+## Install
+
+The plugin is shipped inside the OLP repo at `olp-plugin/`. Two install paths:
+
+### Option A — OpenClaw CLI
+
+```bash
+openclaw plugins install /path/to/olp/olp-plugin/
+```
+
+### Option B — symlink
+
+```bash
+mkdir -p ~/.openclaw/extensions/
+ln -s /path/to/olp/olp-plugin/ ~/.openclaw/extensions/olp
+```
+
+Either path makes the plugin discoverable; restart the gateway to pick it up:
+
+```bash
+openclaw gateway restart
+```
+
+## Configure
+
+Edit `~/.openclaw/openclaw.json` and add a config block for the `olp` plugin:
+
+```json
+{
+  "plugins": {
+    "olp": {
+      "proxyUrl": "http://127.0.0.1:4567",
+      "apiKey": "olp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+    }
+  }
+}
+```
+
+- `proxyUrl` — full URL of the OLP proxy. Default `http://127.0.0.1:4567`
+  (OLP's default since v0.4.0 / D60). Overridable via `OLP_PROXY_URL` or
+  `OLP_PORT` env if you run the gateway under launchd / systemd with custom
+  env.
+- `apiKey` — **owner-tier** OLP API key. Required for the subcommands marked
+  `owner` in the table above. Create one with:
+
+  ```bash
+  # On the OLP host, NOT in chat:
+  npx olp-keys keygen --owner --name=openclaw-bot
+  # Capture the plaintext token from the output — it is printed exactly once.
+  ```
+
+  Use a dedicated bot key (the `--name=openclaw-bot` example above) so you
+  can `npx olp-keys revoke --id=<id>` later without affecting the
+  maintainer's personal key.
+
+## Use
+
+In Telegram or Discord, after the gateway picks up the plugin:
+
+```
+/olp status
+/olp usage
+/olp models
+/olp help
+```
+
+Output is wrapped in a monospace code block. Long responses are truncated
+to fit Telegram's ~4096-char per-message limit; a `... [truncated, use SSH
+for full]` suffix marks where the cut happened.
+
+## Authorization model
+
+The plugin sends `Authorization: Bearer <apiKey>` on every request. OLP's
+server enforces:
+
+- **public-tier endpoints** (`/health`, `/v1/models`) accept any non-revoked
+  key (or no key at all if `auth.allow_anonymous: true`).
+- **owner-tier endpoints** (`/v0/management/*`, `/cache/stats`) reject any
+  non-owner key with 403.
+
+If you see `401 unauthorized` or `403 forbidden` in chat:
+
+- Verify the configured `apiKey` is a non-revoked **owner**-tier key.
+- Verify the key was created on the same host running the OLP server (keys
+  are stored under `~/.olp/keys/` and validated by hash on the server side).
+- Check the OLP server's `/health` directly with `curl` to confirm
+  reachability.
+
+## Port resolution priority
+
+1. `OLP_PROXY_URL` env (full URL) — useful when the gateway runs on a
+   different host than OLP and you proxy in via Tailscale.
+2. `OLP_PORT` env (port only; localhost assumed).
+3. Plugin config `proxyUrl`.
+4. Fallback `http://127.0.0.1:4567`.
+
+## Why no Telegram/Discord SDK dependency
+
+OpenClaw provides the transport (Telegram bot + Discord bot are gateway
+features). This plugin only registers a slash command — it does not open
+its own websocket / long-poll connection. That means:
+
+- No new npm dependency.
+- No bot tokens stored in plugin config.
+- Plugin works for any OpenClaw-supported chat surface (currently Telegram +
+  Discord; future surfaces inherit automatically).
+
+## Cross-references
+
+- [Local `olp` CLI](../bin/olp.mjs) — the full mutating-capable surface.
+- [OCP `/ocp` plugin](https://github.com/dtzp555-max/ocp/tree/main/ocp-plugin) — the OCP predecessor this is ported from.

+ *      shared / persistent surfaces; rotating an owner key or pulling raw audit
+ *      logs from a chat client is a security regression. Use SSH + the local
+ *      `olp` CLI for those operations.
+ *
+ *   2. **Bearer auth required.** OLP enforces multi-key auth at every /v1/* and
+ *      /v0/management/* endpoint (ADR 0007 § 7). Owner-only subcommands need an
+ *      OLP API key with owner_tier="owner". The plugin config carries that key;
+ *      operators are advised to mint a dedicated bot key (NOT the maintainer's
