fix(phase6c): fold review findings — scrub hostname, README prose, parser tests, version citation

P3-1 (binding): scrub private hostname "PI231" from server.mjs comment; replace
with role-based term "the test server". Repo is public — no machine-specific
hostnames may appear.

P3-2: update README.md "How It Works" diagram and prose from stale "claude -p"
to "claude --output-format stream-json", matching the Phase 6c spawn change already
in server.mjs and CHANGELOG.

P2-2: update all five authority citations in server.mjs from bare "claude CLI v2.1.104"
to "claude CLI § <flag> (ported from OLP, verified v2.1.104; behavior stable through
v2.1.158)" — honest about OLP provenance and version range, without inventing new facts.

P2-1: add "Stream-JSON parsers" suite to test-features.mjs (17 new tests, 84 → 101
total). Copies parseStreamJsonLines and parseStreamJsonEvent verbatim from server.mjs
with a MIRRORS header comment; logEvent stubbed to avoid live-server side-effects.
Covers: content_block_delta deltas, assistant-aggregate fallback, no-double-count guard,
aggregate-only short responses, partial-line buffering across two chunks, is_error result
variants, malformed/non-JSON lines, system/user/unknown event types.

 <!-- One or two sentences describing the change and why it is in scope for OCP. -->
 
+## Endpoint Class (REQUIRED)
+
+Per `ALIGNMENT.md` and ADR 0006, every PR that touches a network-facing endpoint must declare its class. Pick the most specific applicable class (Hybrid covers PRs that touch both A and B):
+
+- [ ] **Class A** — forwards a `cli.js` operation (e.g., `/v1/messages`, `/api/oauth/*`, or the Anthropic-side wire call inside `/usage`)
+- [ ] **Class B** — extends an OCP-owned compatibility endpoint (per ADR 0006). Sub-bucket:
+  - [ ] B.1 — OpenAI-compatibility surface (`/v1/chat/completions`, `/v1/models`)
+  - [ ] B.2 — OCP-administrative surface (`/health`, `/dashboard`, `/sessions`, `/logs`, `/status`, `/settings`, `/api/keys*`, `/api/usage`, `/cache*`)
+- [ ] **Hybrid** — touches both classes (e.g., `/usage` if the PR modifies both the Anthropic wire call AND the local synthesis layer). Both evidence sections below must be filled.
+- [ ] **Not endpoint-touching** — refactor / docs / tooling that does not modify any request handler. Skip both evidence sections; explain in Summary.
+

If the endpoint is in fact Class B, switch the class above and use the Class B section instead.)
   <!-- Justification, if applicable. Empty is fine when cli.js does perform the operation. -->
 
 - [ ] **Commit message citations.** Every "Claude Code uses X" or "cli.js uses X" assertion in every commit of this PR is immediately followed by a `cli.js:NNNN` or `cli.js vE4 <functionName>` citation. I have verified this by rereading each commit message.
 
+### If Class B
+
+- [ ] **Authorizing ADR.** Cite the ADR number that authorizes the endpoint this PR modifies (e.g., "ADR 0006 — OpenAI shim scope"). For B.1 endpoints (`/v1/chat/completions`, `/v1/models`), this is ADR 0006. For grandfathered B.2 endpoints, this is "ADR 0006 (grandfathered as of v3.16.4)." For new B.2 endpoints, cite the endpoint's own authorizing ADR; if none exists, the PR cannot proceed — the authorizing ADR must be drafted and merged first.
+  <!-- e.g., ADR 0006 -->
+
+- [ ] **Specification citation.** For B.1 endpoints, link to the relevant section of OpenAI's `/v1/chat/completions` specification (https://platform.openai.com/docs/api-reference/chat/create), including the specific field or behaviour being implemented. For B.2 endpoints with their own ADR, cite the ADR section that specifies the behaviour. For grandfathered B.2 endpoints, the PR must be a behaviour-preserving refactor — link the existing handler code being modified.
+  <!-- B.1 example: OpenAI chat/completions, `response_format` parameter, https://platform.openai.com/docs/api-reference/chat/create#chat-create-response_format -->
+  <!-- B.2 example: ADR 00NN § "Behaviour" -->
+
+- [ ] **No invention beyond the specification.** I confirm this PR does not introduce any field or behaviour not present in OpenAI's spec for the endpoint (B.1) or beyond the scope of the authorizing ADR (B.2). For grandfathered B.2 endpoints, I confirm the change is behaviour-preserving (no contract drift). If something the user actually wants is not in the spec, the right answer is to close this PR and propose an upstream spec change or a new ADR.

 OCP (Open Claude Proxy) is a **proxy layer** for the Claude Code CLI. It forwards, observes, and multiplexes the traffic that `cli.js` already emits. It is **not** an extension layer. If `cli.js` does not perform a given operation, or performs it differently, OCP does not invent one.
 
+This Core Principle applies in full to **Class A** endpoints (the `cli.js`-mirror surface). A second class of endpoint — **Class B**, the OCP-owned compatibility surface — has its own scope discipline anchored to its own specification authority. See "Scope Clarification: OCP-Owned Compatibility Endpoints (Class B)" below and ADR 0006.

 ## Rules
 
+The following Rules apply to **Class A operations** (the `cli.js`-mirror surface — the inbound `/v1/messages` forwarding route, the outbound `/v1/messages` wire call used by `handleUsage()` for rate-limit-header extraction, the OAuth bearer machinery, and any future operations OCP forwards from `cli.js` to Anthropic). For the Class B mapping of each rule, see the Class B section below.
+
 1. **Rule 1 (Grep First).** Before adding, renaming, or changing any endpoint, header, parameter, or response shape, the author must `grep` the reference `cli.js` and record the exact line numbers in the commit message and PR body. An absent grep hit is itself a finding and must be declared.
 
 2. **Rule 2 (No Invention).** OCP must not introduce endpoints, headers, request fields, or response fields that are not present in `cli.js`. Speculative "Claude Code probably uses X" statements are prohibited. If the behavior is not observable in `cli.js`, the feature is out of scope.

+
+## Scope Clarification: OCP-Owned Compatibility Endpoints (Class B)
+
+OCP has two classes of endpoint. Rules 1–5 above were drafted in the aftermath of the 2026-04-11 forwarding drift and are written in the language of a one-to-one proxy; they apply verbatim to **Class A** endpoints. **Class B** endpoints — the OCP-owned compatibility surface where `cli.js` is not the wire authority — have their own scope discipline, anchored to their own specification authority. The full rationale lives in **ADR 0006 (OpenAI Shim Scope)**.
+
+**Class A** — `cli.js`-mirror endpoints. The endpoint exists because `cli.js` performs the equivalent operation and OCP forwards, observes, or multiplexes that operation. Rules 1–5 above apply verbatim. Citation format: `cli.js:NNNN` or `cli.js vE4 <functionName>`.
+
+**Class B** — OCP-owned compatibility endpoints. The endpoint exists because OCP itself surfaces it, with no `cli.js` analogue. Two sub-buckets: **B.1** (OpenAI-compatibility surface — protocol authority is OpenAI's `/v1/chat/completions` specification) and **B.2** (OCP-administrative surface — authority is the ADR that authorized the endpoint's existence).
+
+### Grandfather provision for existing B.2 inventory
+
+ADR 0006 retroactively authorizes the B.2 endpoints listed in the inventory table below, **frozen at their current behaviour as of v3.16.4**. This is a one-time provision; it does not extend to new B.2 endpoints or to B.1 endpoints. Any change to the contract (request shape, response shape, semantics) of a grandfathered B.2 endpoint is treated as a new authorization request and requires either a behaviour-preserving refactor PR or its own ADR. Any new B.2 endpoint, or any new method on a grandfathered B.2 endpoint, requires its own ADR before merge.
+
+### Current Class B inventory
+
+| Endpoint | Method | Sub-bucket | Authorizing ADR |
+|---|---|---|---|
+| `/v1/chat/completions` | POST | B.1 (OpenAI-compat) | ADR 0006 |
+| `/v1/models` | GET | B.1 (OpenAI-compat) | ADR 0006; content sourced from `models.json` per ADR 0003 |
+| `/health` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/dashboard` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/sessions` | GET, DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/logs` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/status` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/settings` | GET, PATCH | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys` | GET, POST | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys/:id` | DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys/:id/quota` | GET, PATCH | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/usage` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/cache/stats` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/cache` | DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+
+**Hybrid note.** `/usage` is a hybrid endpoint: the underlying call to `api.anthropic.com/v1/messages` (used to extract `anthropic-ratelimit-unified-*` headers, per the in-file comment block at `server.mjs` line 845–849) is Class A and requires the standard `cli.js` citation; the local synthesis layer that adds `proxy:` stats and `models:` snapshot is Class B and is authorized by ADR 0006. A PR touching only the wire-call layer is Class A; a PR touching only the synthesis layer is Class B; a PR touching both must satisfy both citation requirements.
+
+### Class B citation requirement
+
+Class B PRs cite **the relevant specification section + the authorizing ADR**, in place of `cli.js:NNNN`. Examples:
+
+- B.1: "OpenAI `chat/completions` API, `response_format` parameter (https://platform.openai.com/docs/api-reference/chat/create), authorized by ADR 0006."
+- B.2 (grandfathered): "Authorized by ADR 0006 (grandfathered as of v3.16.4)."
+- B.2 (with its own ADR): "Authorized by ADR 00NN (the ADR that originally authorized the endpoint)."
+
+### Rule mapping for Class B
+
+| Class A rule | Class B mapping |
+|---|---|
+| Rule 1 (Grep First) | Read the cited OpenAI spec section (B.1) or the authorizing ADR (B.2) before writing code. Record the spec URL and ADR number in the PR body. |
+| Rule 2 (No Invention) | OCP must not introduce fields or behaviour not present in OpenAI's spec for the endpoint (B.1) or outside the scope of the authorizing ADR (B.2). For grandfathered B.2 endpoints, "scope" is the v3.16.4 behaviour snapshot. |
+| Rule 3 (Match the Implementation) | Match OpenAI's spec wire-format (B.1) or the ADR's specified behaviour (B.2). |
+| Rule 4 (Unalignable Features Are Deleted) | A Class B endpoint that maps to nothing in OpenAI's spec **and** lacks an authorizing ADR (including not being in the grandfather inventory) is unalignable and is deleted on the same terms as a Class A unalignable feature. |
+| Rule 5 (Cite Line Numbers in Commits) | Cite the OpenAI spec section URL + authorizing ADR number in the commit body (B.1) or the authorizing ADR number alone (B.2). |
+
+### New Class B endpoint procedure
+
+Any new Class B endpoint, or any new method on an existing Class B endpoint (including grandfathered ones), requires its own ADR before merge. An "ADR-less" new Class B endpoint is itself an alignment finding under Rule 4.

+## v3.16.4 — 2026-05-13
+
+### Refactor — port-literal SPOT + CI guardrail
+
+Closes the structural side of the port-drift cascade addressed by v3.16.2
+and v3.16.3. Those two releases reverted plist / plugin / scripts back to
+3456 line-by-line, but the underlying invitation to drift — a hardcoded
+port literal scattered across six source files — was still intact.
+
+Changes:
+
+- **New `lib/constants.mjs`** — single source of truth for shared literals.
+  Exports `DEFAULT_PORT = 3456`, `LOCAL_HOST = "127.0.0.1"`,
+  `OPENAI_API_BASE = "/v1"`, `LOCAL_PROXY_URL`.
+- **`server.mjs:127`, `setup.mjs:36`, `scripts/upgrade.mjs:137`,
+  `scripts/doctor.mjs:84` + `:205`, `scripts/sync-openclaw.mjs:73`** —
+  all replaced with imports from `lib/constants.mjs`. Behavior is
+  identical; the literal `3456` now exists in exactly one place per
+  language (`lib/constants.mjs` for `.mjs`, `ocp` + `ocp-connect` for
+  bash, `test-features.mjs` for pinned historical-port tests).
+- **`.github/workflows/alignment.yml`** — extended the path filter to
+  `setup.mjs`, `scripts/**`, `lib/**`, `ocp`, `ocp-connect`. Added a new
+  `port-spot` hard-fail job that greps for any hardcoded `3478` or `3456`
+  literal in `.mjs/.js/.ts/.json` outside the EXEMPT_REGEX (which lists
+  `lib/constants.mjs`, `test-features.mjs`, the bash CLIs, docs, and the
+  workflow itself). Any future PR re-introducing a hardcoded port
+  literal will be blocked at CI before it can cascade.
+- Doc comments in `server.mjs` env-var summary and `setup.mjs` usage
+  banner reworded so the literal `3456` no longer appears as
+  documentation text (CI grep is intentionally aggressive — it does not
+  parse comments — so doc strings reference `DEFAULT_PORT from
+  lib/constants.mjs` instead).
+
+No behavior change for any user. `CLAUDE_PROXY_PORT` env var remains
+the runtime override; the only difference is the unset-env fallback
+now flows through one shared constant.
+
+ALIGNMENT.md hard-requirements: this PR modifies `server.mjs` (one-line
+import + one literal swap, mechanical). No cli.js operation changed;
+the citation requirement does not apply. SPOT principle (Rule 2 spirit)
+is the entire motivation.
+
+## v3.16.3 — 2026-05-13
+
+### Fixes — completes v3.16.2 port-drift revert
+
+v3.16.2 reverted the plugin / `openclaw.plugin.json` / README / Mac mini
+plist back to `3456` (the historical source default since `593d0dc`), but
+missed three places in `scripts/` that still defaulted to `3478`. Those
+three lines were the residual cascade source: every time `ocp doctor` or
+`ocp upgrade` ran without `CLAUDE_PROXY_PORT` in the env, they probed
+`3478`, reported "OCP not responding" against a healthy 3456 instance,
+and (in the case of OpenClaw sync follow-ups on the maintainer's host)
+re-introduced 3478 into downstream config.
+
+Changes:
+
+- `scripts/upgrade.mjs:137` — default port `3478` → `3456`.
+- `scripts/doctor.mjs:84` — default port `3478` → `3456`.
+- `scripts/doctor.mjs:205` — default port `3478` → `3456`.
+
+No behavior change for users who set `CLAUDE_PROXY_PORT` explicitly; env
+still takes precedence. The fix only affects the unset-env fallback,
+which now matches `server.mjs:126` and the rest of the codebase.
+
+Test plan: existing `test-features.mjs` cases that pin
+`CLAUDE_PROXY_PORT=3478` continue to pass — they use the env path, not
+the default.
+
+## v3.16.2 — 2026-05-12
+
+### Fixes — corrects v3.16.1
+
+The v3.16.1 fix was directionally correct (plugin now reads env first, falls back to a hardcoded default) but **the narrative and the hardcoded default were both wrong**.
+
+What v3.16.1 said: "OCP server moved to 3478 default in v3.14+; plugin lagged at 3456."
+What is actually true:
+- **OCP server source default has been `3456` since `593d0dc` (initial release) and has never changed.** Every line in `server.mjs`, `setup.mjs`, and the `ocp` CLI still uses `3456` as the documented and code-level default.
+- The single OCP installation observed on `3478` is the maintainer's Mac mini, whose plist was rewritten with `--port 3478` during a PR #71 dogfood smoke-test accident on 2026-05-08 (see `~/.cc-rules/memory/learnings/subagent_setup_mjs_prod_host_collision.md`). The plist drift was never reconciled back to source default, and v3.16.1 incorrectly canonised the post-accident value as if it had been a release decision.
+
+This release:
+- Restores the plugin fallback to `http://127.0.0.1:3456` to match server source default.
+- Updates `openclaw.plugin.json` `configSchema.proxyUrl.default` back to `3456`.
+- Restores README §"Environment Variables" `CLAUDE_PROXY_PORT` default to `3456`.
+- Plugin reads `OCP_PROXY_URL` env (full URL) first, then `CLAUDE_PROXY_PORT` env (port only), then falls back to `3456`. Hosts whose OCP plist injects a non-default port must also inject the same `CLAUDE_PROXY_PORT` into the OpenClaw plist for the plugin to follow.
+- Maintainer's Mac mini plist was reverted from `3478` to `3456` as part of this release deploy (no source change reflects this; it was a one-host correction).

+- No `cli.js` citation needed (no `server.mjs` change). ALIGNMENT.md Rule 2 not engaged.
+
+## v3.16.1 — 2026-05-12 (superseded — narrative incorrect; see v3.16.2 erratum)
+
+### Fixes (as shipped — note erratum above)
+
+- **OCP plugin port lag** — `ocp-plugin/index.js` hard-coded `http://127.0.0.1:3456`. ~~While OCP server moved to 3478 in v3.14+,~~ **(corrected v3.16.2: no such move ever happened.)** The Mac mini's plist was on `3478` only as residue from a dogfood accident. Result: `/ocp` slash commands from the home Telegram bot returned "OCP error: fetch failed". v3.16.1 changed the plugin default to `3478` (wrong direction; v3.16.2 reverts to `3456`).

+
+## v3.16.0 — 2026-05-10
+
+### Features
+
+- **`ocp doctor --check oauth`** (PR #93) — fast path that runs only the OAuth check, skipping
+  version detection / from-version / git operations / models endpoint. ~50ms vs. full doctor's
+  ~200-500ms. Use cases: AI agent repair loops, post-`claude auth login` verify, quick health
+  gates. Help text in `cmd_doctor_help` now reflects working behaviour.
+- **`ocp update --rollback --gc`** — manually garbage-collect old upgrade snapshots.
+  Retention policy: keep last 5 snapshots OR snapshots newer than 30 days OR the single most
+  recent (always-keep safety net). `--dry-run` previews. Successful `ocp update` runs auto-GC
+  at the end of the full path; light path does not (no snapshot created there).
+
+### Behavior changes
+
+- After a successful cross-minor `ocp update`, the auto-GC emits `[gc] removed N old snapshots`
+  to stderr if any were collected. Safe to ignore; manual gc is `ocp update --rollback --gc`.
+
+### Governance
+
+- No `cli.js` citation needed (no `server.mjs` change). ALIGNMENT.md Rule 2 not engaged.
+- PR #93 (--check oauth) merged separately; this release bundles it with the GC feature.
+
+## v3.15.1 — 2026-05-10
+
+### Fixes
+
+- **doctor: dynamic `latest_version` from `origin/main:package.json`** — v3.15.0 doctor used a hard-coded `latest = "v3.14.0"` fallback, which made any v3.15.0+ install report `kind = upgrade` (against a stale value). `ocp update` would then attempt `git checkout v3.14.0` — a downgrade. Doctor now fetches `git -C ~/ocp show origin/main:package.json` to determine the actual latest version; on failure (offline, fresh clone with no remote), falls back to `currentVersion` so `kind = noop` instead of recommending a downgrade.
+
+## v3.15.0 — 2026-05-10
+
+### Features
+
+- **`ocp doctor`** — health & upgrade-readiness check; primary entry for AI-driven debugging.
+  `--json` mode emits a `next_action` with `ai_executable[]` for agents to run verbatim
+  and `human_required[]` for steps requiring the user (typically only OAuth).
+- **`ocp update` cross-version path** — for cross-minor jumps (e.g. v3.10 → v3.14),
+  `ocp update` now runs doctor → snapshot → `setup.mjs` (with the plist env-merge from
+  PR #90) → service restart → post-flight `/health` + `/v1/models` verification.
+  Same-patch updates retain the existing light path; users see no change for routine
+  patch bumps.
+- **`ocp update --rollback`** — restore the most recent (or specified) upgrade snapshot.
+  Snapshots are saved to `~/.ocp/upgrade-snapshot-<ISO-ts>/` and never auto-deleted.
+- **Fresh-install routing** — `ocp update` on installations < v3.4.0 routes to a fresh-install
+  flow (with `--yes` to skip confirmation; AI agents pass this). OAuth survives via Claude
+  Code's credential store; users do not re-OAuth unless their token was independently broken.
+- **AI prompt blocks in README** — §Installation, §Upgrading, and §Troubleshooting each
+  start with a copy-paste prompt for Claude Code / Cursor / Copilot, so users can drive
+  install / setup / upgrade through their existing AI assistant.
+
+### Behavior changes
+
+- `ocp update` may take 10–30s longer when a cross-minor jump triggers the full path
+  (snapshot + post-flight). Patch bumps are unchanged.
+- Pre-v3.4.0 installs are routed to fresh-install rather than failing silently or
+  half-migrating.
+
+### Governance
+
+- No `cli.js` citation needed (no `server.mjs` change). ALIGNMENT.md Rule 2 not engaged.
+- Depends on PR #90 (plist env merge bug fix; merged before this release).
+
+## v3.14.0 — 2026-05-10
+
+### Features (security hardening)
+
+- **Per-key session isolation** (PR #86, S1) — the `sessions` Map in `server.mjs` is now keyed by `${keyName}|${conversationId}` instead of bare `conversationId`. Before this fix, two clients using distinct API keys but the same `session_id` value (e.g. both defaulting to `"default"`) would share the same `cli.js` subprocess and conversation history, creating a cross-tenant leak path. Post-fix each (key, session) pair is isolated end-to-end, extending the per-key cache isolation shipped in v3.13.0 D1 to the session layer.
+- **On-disk credential file modes 0700/0600** (PR #87, S2) — `setup.mjs` now creates `~/.ocp` at mode 0700 and both `admin-key` and `ocp.db` at mode 0600. An idempotent `reconcileFileModes()` call in `server.mjs` startup tightens any existing installation to these modes automatically on every launch, so existing prod boxes fix themselves without manual `chmod`. Before this fix, all three files were created at the process's default umask (typically world-readable 0644 / 0755), leaving plaintext credentials readable by other local users.
+- **`/api/usage` default scope = self; admin all-keys requires `?all=true`** (PR #88, S3) — the usage endpoint now applies a least-privilege default: anonymous callers receive only their own rows, non-admin authenticated callers receive only their own rows, and admin callers receive only their own rows unless they explicitly pass `?all=true`. When `?all=true` is used, an audit log line is emitted. Before this fix, any admin-token holder could silently enumerate usage data for every key on the server.
+
+### Behavior changes
+
+- **Breaking change for admin tooling**: `/api/usage` no longer returns all-keys data by default. Existing cron jobs, dashboards, or scripts that rely on the admin token seeing all-keys output must add `?all=true` to their request URL after upgrading to v3.14.0.
+- **File mode reconcile at server startup** logs a one-line notice per path when mode is tightened (e.g. `[security] tightened ~/.ocp/ocp.db → 0600`). No action is required from the operator; the reconcile is idempotent and silent when modes are already correct.
+- **`sessions` Map key is now `${keyName}|${conversationId}` internally.** No client-visible wire change — the `session_id` field in request/response is unchanged.
+
+### Verification
+
+- Stress-test pass: 11/11 phases including S1/S2/S3 security regression checks (Phase E, I, J). 35-minute sustained run, 60 calls, 0 errors, 0 timeouts. RSS dropped 51→47 MB across the window. Per-key cache isolation, singleflight, cache_control bypass, quota enforcement, file-mode reconcile, and scope guard against escalation all verified against running code.
+
+### Governance
+
+- All three PRs (#86, #87, #88) include the explicit `cli.js`-citation-not-applicable disclaimer (per PR #75 pattern) since they are OCP-internal access-control, session-state, and file-permission changes with no corresponding `cli.js` operation to cite.
+
+### No new env vars / no public API surface change beyond the documented breaking change
+
+This release adds no new env vars or endpoints. The only externally visible change is the `/api/usage` scope guard (breaking for admin all-keys consumers; see Behavior changes above).
+
+## v3.13.0 — 2026-05-07
+
+### Features (cache layer hardening)
+
+- **Per-key cache isolation** (D1) — the cache key now includes the API key id, so distinct keys never share cache entries. Anonymous/unauthenticated callers share one `anon` pool. Hash format upgraded to `v2`; legacy v1-format rows orphan and are reaped by the existing TTL cleanup interval (no migration script).
+- **`cache_control` bypass** (D2) — when a request carries an Anthropic `cache_control` annotation (top-level or nested in a content array), OCP skips its own cache entirely. The caller is using Anthropic-side prompt caching deliberately, and OCP must not interfere. A `cache_skipped{reason: cache_control_present}` log line is emitted on bypass.
+- **Chunked stream replay** (D3) — when a streaming request hits the cache, the cached content is now emitted as multiple SSE chunks (80 codepoints/chunk, codepoint-safe via `Array.from()`) instead of a single large delta. Multibyte characters (CJK / emoji) stay intact.
+- **Singleflight stampede protection** (D4) — concurrent identical cache-miss requests now share one upstream `cli.js` spawn instead of spawning N processes. Followers receive byte-identical responses to what the leader returns. All-or-nothing failure semantics: if the leader errors, all followers receive the same error. Streaming-path singleflight is explicitly out of scope (TODO left for follow-up).
+
+### Behavior changes
+
+- `/cache/stats` response now includes additive fields `inflight` and `requesters` (current in-flight singleflight entries and total waiting callers). Existing fields `entries`, `totalHits`, `sizeBytes` are preserved unchanged.
+
+### Governance
+
+- New ADR [`docs/adr/0005-no-multi-provider.md`](docs/adr/0005-no-multi-provider.md): OCP stays single-provider (Anthropic via `cli.js` spawn). Multi-provider gateway refactor explicitly out of scope; cache improvements are explicitly in scope.
+- Design spec for this release: [`docs/superpowers/specs/2026-05-07-cache-upgrade-design.md`](docs/superpowers/specs/2026-05-07-cache-upgrade-design.md).
+

+This release adds no new env vars or endpoints. All four improvements are internal correctness/concurrency upgrades to the existing `CLAUDE_CACHE_TTL`-gated cache layer. No client-observable wire shape change.
+
+## v3.12.0 — 2026-04-25
+
+### Features
+
+- **Streaming heartbeat** — opt-in SSE comment frame (`: keepalive\n\n`) emitted during silent windows on the streaming response. Controlled by `CLAUDE_HEARTBEAT_INTERVAL` env var (ms; `0` = disabled, default). Covers both pre-first-byte and mid-stream tool-use pauses. Addresses #47. See [design doc](docs/superpowers/specs/2026-04-25-47-sse-heartbeat-design.md).
+- **`X-Accel-Buffering: no`** response header added to SSE responses so heartbeats survive nginx/Cloudflare default buffering.
+
+### Behavior changes
+
+- SSE headers are now sent immediately after the claude CLI spawns successfully, not on first stdout byte. The rare "spawn succeeded but subprocess died before any byte" path now closes the SSE stream cleanly rather than returning a JSON error.
+
+### Config additions
+
+| Variable | Default | Description |
+|---|---|---|
+| `CLAUDE_HEARTBEAT_INTERVAL` | `0` (disabled) | Interval in ms for SSE keepalive comment frames on streaming path. Resets on every real frame. |

 One proxy. Multiple IDEs. All models. **$0 API cost.**
 
+## Why OCP?
+
+There are several Claude proxy projects. OCP picks a specific lane: **align tightly with what `cli.js` actually does, observe + multiplex what's already there, don't extend the protocol.** What you get:
+
+- **LAN multi-user keys** (v3.7.0) — share one Claude Pro/Max subscription with family, friends, or your own devices. Each user gets a per-key API token (no OAuth session leak), with independent usage tracking and one-line revocation.
+- **`ocp-connect` one-shot IDE setup** — one command on the client machine detects and configures Claude Code, Cursor, Cline, Continue.dev, OpenCode, and OpenClaw. No pasting `OPENAI_BASE_URL` six times.
+- **Response cache with per-key isolation + singleflight** (v3.13.0). Optional SHA-256 prompt cache, isolated per API key (cross-user pollution is impossible by hash construction, not by application logic), with stampede protection on concurrent identical prompts. Off by default. ([PR #65](https://github.com/dtzp555-max/ocp/pull/65), [PR #66](https://github.com/dtzp555-max/ocp/pull/66))
+- **Per-key request quotas** (v3.8.0). Daily / weekly / monthly limits per key — set a kid's iPad to 20/day, a partner's laptop to 100/week. ([PR #18](https://github.com/dtzp555-max/ocp/pull/18))
+- **SSE heartbeat for long reasoning** ([v3.12.0](https://github.com/dtzp555-max/ocp/releases/tag/v3.12.0), opt-in). If you've ever watched your IDE die at the 60s idle mark during a long Claude tool-use pause — that's nginx/Cloudflare default behavior. OCP emits an SSE comment frame to keep the connection alive without polluting the response. ([PR #49](https://github.com/dtzp555-max/ocp/pull/49))
+- **`cli.js` alignment + CI guardrail.** LLM-assisted code drifts easily — it's tempting to invent plausible-looking endpoints that `cli.js` doesn't actually use. [`ALIGNMENT.md`](./ALIGNMENT.md) is binding: every endpoint OCP exposes must cite a `cli.js` line. The [`alignment.yml`](./.github/workflows/alignment.yml) CI workflow blocks PRs that introduce known-hallucinated tokens. The payoff is boring: your setup keeps working when `cli.js` ships its next minor.
+- **`models.json` single source of truth** (v3.11.0). Adding a model is one file edit; both `/v1/models` and the OpenClaw bootstrap derive from it. ([PR #30](https://github.com/dtzp555-max/ocp/pull/30))

+### Comparison
+
+OCP and the alternatives serve adjacent but distinct needs. Pick the one that fits your use case:
+
+| Feature | OCP | claude-code-router | anthropic-proxy |
+|---|---|---|---|
+| Forwards Claude Code subscription as OpenAI API | yes | yes | yes |
+| Routes to multiple model backends (OpenAI, Gemini, etc.) | no | yes | partial |
+| SSE heartbeat for long reasoning | yes (opt-in) | no | no |
+| Per-key quota + LAN multi-user keys | yes | no | no |
+| Response cache | yes (opt-in) | no | no |
+| OpenClaw / IDE auto-config | yes | no | no |
+| Model-routing rules / model-switching | no | yes | no |
+| GitHub stars / ecosystem size | small | large | mid |
+| Governance discipline (CI-enforced alignment with cli.js) | yes | n/a | n/a |
+
+**Plain English**: `claude-code-router` is the routing-and-switching power tool — pick it if you want to mix Anthropic, OpenAI, Gemini, and local models behind one endpoint. `anthropic-proxy` is the minimal forwarder. **OCP focuses on disciplined `cli.js`-aligned forwarding plus subscription multiplexing** — pick it if you want to share one Claude Pro/Max subscription across IDEs, devices, and people, with LAN auth, quotas, and a governance contract that prevents endpoint drift.

+OCP is single-maintainer + LLM-assisted, currently pre-1.0. It runs the maintainer's daily Claude Code workflow. If something breaks, [open an issue](https://github.com/dtzp555-max/ocp/issues).

-- [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) installed and authenticated (`claude auth login`)
+- Node.js 22.5+ (Node 23+ recommended — `node:sqlite` is fully stable without flags from 23.0; on 22.5–22.x it works behind `--experimental-sqlite`)
+- `git`
+- [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) — install and authenticate:

+#### Headless install notes
+
+OCP is designed for always-on devices that often don't have a desktop browser — Mac mini, NAS, Raspberry Pi, cloud VPS. The Claude CLI auth flow still works headless:
+
+**Option 1 — interactive OAuth over SSH (one-shot).** `claude auth login` prints a URL + 8-digit code. Open the URL on **any** device with a browser (your laptop, phone), sign in to your Anthropic account, and paste the code back into the SSH session. No browser needed on the server itself.
+
+**Option 2 — long-lived token (auth once, no re-prompts).**
+
+```bash
+claude setup-token   # subscription-backed long-lived token
+```
+
+Same Claude subscription as Option 1; the token is stored in Claude CLI's normal config location. Useful when you'd rather not redo the OAuth flow when sessions expire.
+
+If `claude auth login` errors out with something like `cannot open browser`, you've hit the same case — fall back to either option above.

+
 ### Anonymous Access (optional)
 
 In `multi` mode, the admin can designate a single well-known "anonymous" key that bypasses `validateKey()` and grants public read/write access. This is useful for letting LAN users (or clients like OpenClaw multi-agent setups) connect without individual per-user keys.
 
 **Enable**:
 
+The anonymous key is wired into the service unit (launchd plist on macOS, systemd unit on Linux) at install time. Export `PROXY_ANONYMOUS_KEY` in your shell before running `setup.mjs`, and `setup.mjs` will write it into the service unit env so the auto-started proxy picks it up:
+
 ```bash
 export PROXY_ANONYMOUS_KEY=ocp_public_anon   # or any string of your choice
-ocp start                                    # or however you start the server
+node setup.mjs --bind 0.0.0.0 --auth-mode multi
 ```
 
+If OCP is already installed without it, re-export the env var and re-run `node setup.mjs` (the installer is idempotent — it refreshes the service unit). Then `ocp restart` so the running proxy picks up the new env. Setting `PROXY_ANONYMOUS_KEY` only in your interactive shell **does not** affect the auto-started proxy — the service unit is the source of truth for its environment.
+
 **Client side**: the anonymous key value is exposed via `GET /health` as the field `anonymousKey` (null when not set). Clients like `ocp-connect` can auto-discover and use it, so the end user doesn't need to get a personal key from the admin.
 
 **Security note**: setting this env var is an **opt-in** to public access — anyone who can reach your OCP endpoint can use it, up to any rate limits you configure. Don't enable this on internet-exposed OCP instances without additional protection.

+- Cache key = SHA-256 of `v2|<keyId or "anon">|model + messages + temperature + max_tokens + top_p`
+- **Per-key isolation** — different API keys never share cache entries; anonymous callers share one `anon` pool
 - Cache hits return instantly — no Claude CLI process spawned
-- Works for both streaming and non-streaming requests
+- **Streaming hits** are replayed as multiple SSE chunks (80 codepoints each), not one large delta — incremental render preserved
+- **`cache_control` bypass** — if a request carries an Anthropic `cache_control` annotation (top-level or nested in `content[]`), OCP skips its own cache entirely so it doesn't interfere with Anthropic-side prompt caching
+- **Singleflight stampede protection** — concurrent identical cache-miss requests share one upstream `cli.js` spawn; followers receive byte-identical responses to the leader's call. Non-streaming path only (streaming-path singleflight is a known TODO)

+### Streaming heartbeat
+
+When `CLAUDE_HEARTBEAT_INTERVAL` is set to a positive integer (milliseconds), OCP emits an SSE comment frame (`: keepalive\n\n`) on streaming responses whenever the stream has been idle for that duration. The timer resets on every real chunk, so heartbeats only fire during genuine silent windows (for example, Claude CLI tool-use pauses of 30s–5min, or a long "processing large contexts" delay before the first token).
+
+Use cases: downstream HTTP clients or load balancers with idle-connection timeouts that would otherwise abort a slow-but-alive request. `CLAUDE_HEARTBEAT_INTERVAL=30000` (30s) is a reasonable starting value if your downstream has a 60s idle timeout.
+
+Heartbeats are inert SSE comment lines — conforming SSE clients ignore them. If your downstream client's SSE parser crashes on comment frames, leave this disabled (the default) and file an issue so we can consider an alternate frame format.
+
+OCP also sends `X-Accel-Buffering: no` on SSE responses so nginx-default proxy buffering does not hold heartbeats in an upstream buffer.

+
+- **[`ALIGNMENT.md`](./ALIGNMENT.md)** — the constitution. Every endpoint OCP exposes must correspond to something `cli.js` actually does, with a line-number citation. Background in [ADR 0002](./docs/adr/0002-alignment-constitution.md).

+
+## Support OCP
+
+OCP has been **open source from day one** — not a freemium tool, not a commercial product turned open, just open. It will stay that way forever. No paid tiers, no premium features, no "Pro" version locked behind a paywall.
+
+I built it because my family and I needed it. We use OCP every day across our own machines and IDEs — keeping one Claude Pro/Max subscription powering everything, saving the per-token API cost we'd otherwise pay. It's been quietly heartwarming to hear from users online who say OCP has saved them money the same way it saves ours. That's the whole point.
+
+Behind every version are hundreds of hours that don't show up in commits: building it from scratch, adding new features as the Claude Code ecosystem evolves, debugging across Mac / Windows / Linux machines, validating against half a dozen IDEs (Claude Code, Cursor, Cline, OpenCode, Aider, Continue.dev, OpenClaw), tracking down `cli.js` drift, OAuth refresh edge cases, SSE streaming quirks, concurrency leaks, and the occasional incident that turns into a multi-day investigation (the [2026-04-11 alignment drift](./docs/adr/0002-alignment-constitution.md), the [v3.11.1 concurrency leak](./CHANGELOG.md), the v3.12 SSE replay regression).
+
+**The commitment**: this project will keep being updated, keep getting new features, and will stay open source as long as I'm able to maintain it.
+
+**Please try it.** If something breaks or could be better, [open an issue](https://github.com/dtzp555-max/ocp/issues) — feedback is genuinely what keeps the project moving.
+
+And if OCP saves you (or your team, or your family) real money and you'd like to chip in toward the next debugging session:
+
+- ☕ **[Buy me a coffee](https://buymeacoffee.com/dtzp555)**

+## Context
+
+OCP's `server.mjs` reached 1667 lines and now provides response cache, per-key quota, session tracking, model-level stats, and SSE heartbeat — all targeting a single backend path: `spawn` the locally installed `cli.js` and let it transact with `api.anthropic.com`. This architecture is the source of OCP's only real differentiator: **`cli.js` behavior-level alignment** (session create-vs-resume semantics, tool_use id reuse, SSE quirks, etc.) — none of which a generic LLM gateway has, because none of them speak this protocol.
+
+The maintainer evaluated extending OCP to support OpenAI / Gemini / OpenRouter / Together / Groq / Ollama — i.e., turning OCP into a multi-provider gateway resembling Helicone, LiteLLM, OpenRouter, or Portkey. The motivation for that extension: reduce dependency on Anthropic, broaden OCP's commercial surface, and stop being grayscale-positioned (the `cli.js` spawn pattern depends on the local Pro/Max subscription, which Anthropic could fingerprint and disable).
+
+The honest engineering estimate for that extension:
+
+| Phase | Net New LOC | Calendar Time (part-time) |
+|---|---|---|
+| Provider abstraction + OpenAI | ~1230 + schema migration | 2 weeks |
+| Add Gemini | ~550 | +1.5 weeks |
+| OpenAI-compatible family (OpenRouter / Together / Groq) | ~300 | +1 week |
+| Tests, docs, hardening | — | +1.5 weeks |
+| **Multi-provider v1** | ~2080 | **~7 weeks focused** |
+
+That number is not the real cost. The real cost is **strategic**:
+
+1. **Loss of unique value.** `cli.js` behavior alignment is meaningless for OpenAI / Gemini / Ollama traffic. Going multi-provider means OCP's only moat applies to ~30% of its surface; the other 70% is generic gateway code already done better by Helicone / LiteLLM.
+
+2. **Hybrid architecture awkwardness.** A multi-provider OCP would have two paths: `spawn(cli.js)` for Claude (still grayscale, depends on Pro subscription), and direct API call for everyone else (clean, BYOK). Customers asking "what is OCP?" would hear two different answers depending on which model they pick. This is worse than either pure path.
+
+3. **Direct competition with funded incumbents.** Helicone (~$5M raised, YC W23), OpenRouter (~$1B valuation), LiteLLM (significant enterprise revenue), Portkey, Langfuse, Cloudflare AI Gateway — all already do multi-provider gateway with mature dashboards, audit logs, SOC2, and team features. OCP would enter that market 2+ years late with one engineer.
+
+4. **The grayscale problem isn't solved by adding providers.** As long as OCP keeps the `cli.js` spawn path for Anthropic, it remains grayscale for that path; adding OpenAI alongside doesn't make the Anthropic path any less dependent on a Pro/Max subscription that wasn't licensed for proxying.
+
+The maintainer's separate decision (recorded in personal notes, not this repo) is that **OCP itself will not be commercialized**; it will remain a personal power tool plus open-source contribution. Any commercial gateway work, if pursued, will start from a clean codebase with BYOK from day one — not from OCP.
+
+Given that, the multi-provider extension would buy OCP nothing: not a moat, not commercial readiness, not even meaningfully better personal utility (the maintainer overwhelmingly uses Claude).
+
+## Decision
+
+OCP stays single-provider. Specifically:
+
+1. **No new providers added to `server.mjs`.** The dispatch path remains `spawn(cli.js) → api.anthropic.com`. Pull requests that introduce a `providers/` directory or a model-to-provider router are declined on the basis of this ADR.
+
+2. **`models.json` schema stays Anthropic-only.** No `provider` field, no per-model cost/capability metadata that anticipates other providers. If non-Anthropic models ever need to be referenced (e.g., for OpenClaw provider list completeness), they live in a separate file or in OpenClaw's own config — not in OCP's SPOT.
+
+3. **Cache improvements are in scope.** The existing response cache (in `keys.mjs`: `cacheHash` / `getCachedResponse` / `setCachedResponse` / `clearCache`) is acceptable to upgrade with stream replay, stampede protection (singleflight), per-key isolation, and Anthropic `cache_control` awareness. These reinforce the single-provider position; they do not create provider-extension surface area.
+
+4. **Anthropic alignment work continues to be encouraged.** Anything that deepens `cli.js` behavior alignment — session lifetime, tool_use id semantics, SSE behavior, multi-account routing, model-tier observability — is the project's actual value and should be prioritized over generic-gateway features.
+
+5. **Commercial work, if pursued, starts elsewhere.** A separate repository, separate name, BYOK from day one, no `cli.js` spawn. That repo is out of scope for OCP and is not bound by this ADR.
+
+## Consequences
+
+**Positive**
+
+- Project scope stays bounded. The maintainer can keep evolving OCP at part-time pace without the multi-provider maintenance burden (every provider's API breaks at some point and demands attention).
+- The unique value (`cli.js` alignment) is preserved and continues to compound — every new alignment fix increases OCP's distance from generic gateways.
+- Future contributors reading the code see one architecture, not a hybrid; debugging stays tractable.
+- Decisions about commercialization are decoupled from OCP's technical evolution. OCP can stay grayscale-personal-tool indefinitely without that being a blocker for any future commercial product.
+
+**Negative**
+
+- OCP cannot serve any user who needs OpenAI / Gemini / local LLM access. Those users must route through a different gateway (Helicone, LiteLLM, OpenRouter) or call providers directly.
+- If Anthropic substantially changes `cli.js` (e.g., adds client attestation, removes the spawn-and-forward pattern, or migrates `claude` to a non-CLI form factor), OCP's core architecture breaks and there is no second backend to fall back to.
+- The maintainer must resist a recurring temptation: "while I'm in here, let me just add OpenAI." The whole point of this ADR is to make that temptation cost a documented amendment, not a quiet PR.
+
+**Neutral**
+
+- This ADR records a non-decision in code: nothing in `server.mjs` changes today. Its purpose is to make future contributors (including the maintainer) explain themselves before going against it. Per the project's PR template and Iron Rule 11, an amendment to this ADR is the gating step before any provider-extension PR.
+
+## Trigger conditions for revisiting this ADR
+
+This ADR should be revisited (and possibly amended or superseded) if any of the following occur:
+
+1. Anthropic ships a feature that breaks the `cli.js` spawn pattern OCP depends on, and the maintainer wants to keep OCP useful.
+2. The maintainer makes a deliberate decision to commercialize OCP (rather than start a separate codebase). This requires explicit re-scoping; "let me try" is not enough.
+3. A genuine user need emerges — e.g., the maintainer themselves starts using OpenAI / Gemini frequently from Claude Code workflows — that single-provider OCP cannot serve.
+
+In all three cases, the response is **first amend this ADR**, then write code. Order is not optional.

+# 0006 — OpenAI Shim Scope: Class A vs Class B Endpoints
+
+- **Date**: 2026-05-20
+- **Status**: Proposed — owner reviewing
+- **Authors**: project maintainer (with AI drafting assistance)
+- **Related**: `ALIGNMENT.md` (the constitution); ADR 0002 (Alignment Constitution provenance, PR #20, commit 2853088); PR #99 by external contributor (triggering incident — OpenAI `response_format` honoring on `/v1/chat/completions`)
+
+## Context
+
+`ALIGNMENT.md` was drafted in the aftermath of the 2026-04-11 drift (commit `b87992f` — fabricated `/api/oauth/usage` endpoint) and ratified in PR #20 / commit 2853088. Its five Rules are written in the language of a one-to-one proxy: Rule 1 (Grep First), Rule 2 (No Invention), Rule 3 (Match the Implementation), Rule 4 (Unalignable Features Are Deleted), Rule 5 (Cite Line Numbers in Commits). All five anchor explicitly on `cli.js` as the golden reference. This is correct and binding for the endpoints OCP was originally designed to forward — `/v1/messages`, `/api/oauth/*`, and the rate-limit-header extraction path that backs `/usage` — because for those, `cli.js` is the literal wire authority and any deviation is a drift risk.
+
+OCP also exposes a second class of endpoint that the constitution does not currently distinguish: **OpenAI-compatible surface** that exists so non-Claude-Code clients (Honcho, OpenWebUI, OpenAI SDK consumers, BYO scripts) can talk to claude via OCP. The flagship is `/v1/chat/completions`, which translates between OpenAI's request/response schema and `cli.js`'s native protocol. `cli.js` never speaks OpenAI's wire format — by construction it cannot, because OpenAI and Anthropic are different vendors with different protocols. There is no `cli.js:NNNN` to cite for OpenAI's `messages[].role` field handling, OpenAI's streaming `delta` shape, OpenAI's `stop` event names, or OpenAI's `response_format` parameter. The protocol authority for these is OpenAI's published specification, not `cli.js`.
+
+The structural gap surfaced when PR #99 (external contributor `jaekwon-park`) added support for the OpenAI `response_format` request field on `/v1/chat/completions`. A strict reading of Rule 2 ("OCP must not introduce request fields that are not present in `cli.js`") blocks the PR. But the same strict reading also blocks the existence of `/v1/chat/completions` itself — every OpenAI-shaped field on that endpoint is, by definition, not in `cli.js`. The endpoint has been in OCP since before the constitution was written and is used by real downstream consumers. The constitution and the endpoint cannot both be correct under the current reading.
+
+The 2026-04-11 drift remains the cautionary tale that drove the constitution and remains binding. The drift was not "OCP exposed an endpoint that wasn't in `cli.js`" — it was specifically "OCP claimed to forward `cli.js`'s `/api/oauth/usage` call when no such call exists in `cli.js`." That is a Class A failure mode: a forwarding endpoint that lied about what it was forwarding. The fix to that failure mode (Rules 1, 2, 3, 5; CI blacklist; reviewer gate) was correct then and is correct now. This ADR does not relitigate that decision and does not soften Rules 1–5 for the class of endpoint they were designed to discipline.
+
+What this ADR does is acknowledge that OCP has two classes of endpoint, and that the discipline that fits Class A does not fit Class B without distortion. Class B needs its own anchor (OpenAI's specification) and its own authorization gate (an ADR per endpoint), so contributors know exactly which rule set applies to their PR and so Class B never becomes a backdoor for "OCP can do anything OpenAI-shaped."
+
+## Decision
+
+Introduce an explicit two-class taxonomy of OCP endpoints:
+
+- **Class A — `cli.js`-mirror endpoints.** Endpoints that exist because `cli.js` performs the equivalent operation and OCP forwards, observes, or multiplexes that operation. Rules 1–5 of `ALIGNMENT.md` apply verbatim. The citation requirement is `cli.js:NNNN` (or `cli.js vE4 <functionName>`).
+
+- **Class B — OCP-owned compatibility endpoints.** Endpoints that exist because OCP itself surfaces them, with no `cli.js` analogue. They fall into two sub-buckets:
+  - **B.1 — OpenAI-compatibility surface.** Endpoints implementing OpenAI's published API contract so non-Anthropic clients can use OCP. The protocol authority is OpenAI's specification.
+  - **B.2 — OCP-administrative surface.** Endpoints that exist purely to operate the proxy itself (health, dashboard, key management, cache control). The authority for these is the ADR that authorized the endpoint's existence.
+
+For Class B endpoints, the citation requirement shifts from `cli.js:NNNN` to **(a)** the relevant specification section (OpenAI spec section for B.1, or the authorizing ADR for B.2) **and (b)** the ADR that authorized the endpoint's existence in the first place.
+
+### Grandfather provision for existing B.2 inventory
+
+ADR 0006 retroactively authorizes the existing B.2 endpoints listed in the inventory table below, **frozen at their current behaviour as of v3.16.4**. This is a one-time grandfather provision intended to avoid a 12-ADR back-fill burden for endpoints that have existed in OCP since before any constitutional governance was written.
+
+The grandfather provision is narrowly scoped:
+
+- It covers only the B.2 endpoints enumerated in the inventory table as of this ADR's merge date.
+- It freezes those endpoints at their **current behaviour**. Any change to the request shape, response shape, or semantics of a grandfathered B.2 endpoint is treated as a new authorization request and requires either (a) a behaviour-preserving refactor PR with no contract change, or (b) its own ADR.
+- It does **not** authorize new B.2 endpoints. Any new B.2 endpoint, or any new method on a grandfathered B.2 endpoint, requires its own ADR before merge.
+- It does **not** extend to B.1 (OpenAI-compat) endpoints. B.1 endpoints are bounded by OpenAI's published specification, not by a behaviour snapshot — there is no grandfather equivalent for them.
+
+The structural intent is: take the one-time hit of declaring "current B.2 surface is authorized" cleanly, then make every future addition pay the ADR-per-endpoint cost. This prevents Class B from becoming a backdoor for general OCP-owned-surface invention while not blocking the present ADR on twelve back-fill PRs.
+
+### Current Class B inventory (enumerated from `server.mjs`)
+
+The following endpoints exist today in `server.mjs` and are Class B (no `cli.js` analogue):
+
+| Endpoint | Method | Sub-bucket | Authorizing ADR |
+|---|---|---|---|
+| `/v1/chat/completions` | POST | B.1 (OpenAI-compat) | ADR 0006 |
+| `/v1/models` | GET | B.1 (OpenAI-compat) | ADR 0006; content sourced from `models.json` per ADR 0003 |
+| `/health` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/dashboard` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/sessions` | GET, DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/logs` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/status` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/settings` | GET, PATCH | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys` | GET, POST | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys/:id` | DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/keys/:id/quota` | GET, PATCH | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/api/usage` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/cache/stats` | GET | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+| `/cache` | DELETE | B.2 (administrative) | ADR 0006 (grandfathered as of v3.16.4) |
+
+For Class A reference, the current Class A inventory is `/v1/messages` (forwarded directly to `api.anthropic.com/v1/messages`) and the OAuth bearer / rate-limit-header machinery used by `handleUsage()` (which calls `https://api.anthropic.com/v1/messages` to extract `anthropic-ratelimit-unified-*` headers, per the in-file comment at line 845–849). The `GET /usage` endpoint surface itself is Class B (administrative augmentation: it adds `proxy:` and `models:` blocks not present in any upstream API), but the data fetch underlying it is Class A — see "Hybrid endpoints" below.
+
+### Hybrid endpoints
+
+`/usage` is a hybrid: the wire call out to `api.anthropic.com/v1/messages` is Class A and must continue to cite `cli.js`; the local synthesis on top (`proxy:` stats block, `models:` snapshot, response shape) is Class B and is authorized by this ADR. Any future change strictly to the wire-call layer is Class A; any change strictly to the synthesis layer is Class B. A PR touching both must satisfy both citation requirements.
+
+## What does NOT change
+
+The following continue to apply verbatim and are not weakened by this ADR:
+
+- **Rules 1, 2, 3, 4, 5 of `ALIGNMENT.md`** for all Class A endpoints. The 2026-04-11 drift discipline is unchanged. Class A PRs still require `cli.js:NNNN` citations, still must match `cli.js`'s wire format byte-for-byte, and still face the Unalignable Policy if the citation cannot be produced.
+- **CI blacklist** (`.github/workflows/alignment.yml`). The known-hallucinated token list (currently `api.anthropic.com/api/oauth/usage`) continues to be greppable-and-failable on every PR.
+- **Reviewer gate** (CLAUDE.md hard requirements + Iron Rule 10). Implementation author may not self-approve; a fresh-context reviewer opens `cli.js` at the cited lines for Class A PRs.
+- **Annual Alignment Audit** on 11 April. The Class A audit (re-verify each `server.mjs` Class A reference against the pinned `cli.js` SHA-256) continues unchanged.
+- **Unalignable Policy.** A Class A endpoint that cannot be traced to a `cli.js` reference is still deleted, not deprecated.
+- **Historical Lesson section in `ALIGNMENT.md`.** The 2026-04-11 drift remains the named cautionary incident, with commit SHAs intact.
+
+## What additionally applies to Class B
+
+The following are new and apply only to Class B endpoints:
+
+1. **OpenAI specification as protocol authority (B.1).** The OpenAI compatibility surface follows OpenAI's published `/v1/chat/completions` specification (https://platform.openai.com/docs/api-reference/chat/create) — not OCP imagination, not "OpenAI probably does X," not generalization from adjacent OpenAI endpoints. The same anti-invention discipline that Rule 2 imposes for `cli.js` applies, with OpenAI's spec substituted as the reference.
+
+2. **ADR-authorized endpoint existence.** Any new Class B endpoint, or any new Class B endpoint method, requires its own ADR before merge. The grandfather provision above covers existing B.2 inventory only. An "ADR-less" Class B endpoint added after this ADR merges is itself an alignment finding and is subject to deletion under a Class B equivalent of the Unalignable Policy (see Rule 4 mapping in `ALIGNMENT.md`'s new section).
+
+3. **Class B citation format.** Class B PRs cite (a) the relevant specification section and (b) the authorizing ADR. Example for B.1: "OpenAI `chat/completions` API, `response_format` parameter (https://platform.openai.com/docs/api-reference/chat/create), authorized by ADR 0006." Example for B.2: "Authorized by ADR 0006 (grandfathered)" for grandfathered endpoints, or "Authorized by ADR 00NN" for endpoints with their own ADR.
+
+4. **Class B audit cadence.** Class B endpoints are audited annually alongside the Class A audit. B.1 endpoints are audited against OpenAI's current `/v1/chat/completions` specification snapshot. B.2 endpoints (grandfathered or ADR-specific) are audited against their authorizing ADR — for grandfathered endpoints, the audit verifies the endpoint behaviour still matches its v3.16.4 snapshot; for ADR-specific endpoints, the audit verifies behaviour still matches the ADR. The B.1 specification pin lives in `docs/openai-compat-pin.md` (to be created alongside the first B.1 audit; not a prerequisite for this ADR to land).
+
+5. **Reviewer expectation.** The fresh-context reviewer for a Class B PR opens the cited OpenAI spec section (B.1) or the authorizing ADR (B.2) instead of opening `cli.js`. The "I am not the commit author" rule and the "explicit approval comment naming the verified reference" rule continue.
+
+## Consequences
+
+**Positive**
+
+- PR #99 becomes mergeable with a one-line scope declaration ("Class B — extends `/v1/chat/completions` per ADR 0006") plus the existing alignment-evidence section adapted to Class B citation format. The structural ambiguity that blocked it is removed.
+- Future Class B contributors have a clear template and a defensible scope: "extend `/v1/chat/completions` for an OpenAI-spec field that's already in OpenAI's spec" is a well-formed PR; "add a new OCP-invented field that looks OpenAI-shaped" is not, and the same anti-invention discipline that protects Class A protects Class B.
+- The Class A surface is structurally unchanged. Reviewers reading the new `ALIGNMENT.md` see a clean Class A regime with all five Rules intact, plus an enumerated and explicitly scoped Class B carve-out.
+- The administrative endpoint surface (B.2) is no longer in a "is this even allowed under the constitution?" limbo. The grandfather provision cleanly authorizes the current inventory; new B.2 endpoints must earn their ADR.
+
+**Negative**
+
+- OCP now maintains a second alignment surface. OpenAI's `/v1/chat/completions` specification is also a moving target (OpenAI ships changes more than once per year, including breaking ones), so the B.1 audit has real work attached.
+- The grandfather provision freezes the current B.2 behaviour. If a grandfathered B.2 endpoint has a latent bug or undesirable behaviour, "fixing" it is a contract change and now requires an ADR (or a behaviour-preserving refactor). This is intentional friction to prevent silent contract drift.
+- Contributors must now choose Class A or Class B on every PR. Some will misclassify. The PR template's required Class A/B radio (see PR template update) and the reviewer's spec-or-cli verification step are the structural counter-measures.
+
+**Mitigations**
+
+- The Class B inventory is small (currently 14 endpoints) and is enumerated explicitly in `ALIGNMENT.md`. New entries require an ADR per item 2 above, so the inventory cannot grow silently.
+- Anthropic-side change frequency (which drives Class A audit cost) is structurally higher than OpenAI's `chat/completions` shape, which has been stable across multiple OpenAI API versions. The marginal B.1 audit cost is low. The grandfathered B.2 audit cost is also low — most of those endpoints have not changed in months.
+- The B.1 specification pin in `docs/openai-compat-pin.md` lets the audit anchor on a specific OpenAI spec snapshot, the same way the Class A pin anchors on a specific `cli.js` SHA-256. Drift detection then works the same way for both classes.
+
+## Historical Lesson — explicit non-relitigation
+
+This ADR does not relitigate the 2026-04-11 drift. The drift commit `b87992f` was Class A — it claimed `cli.js` forwarded a call that `cli.js` did not in fact make. The fix (constitution + CI blacklist + reviewer gate) was correct and remains binding for Class A. This ADR carves out Class B because the discipline that fits Class A does not fit a class of endpoint where `cli.js` is not the wire authority — not because the discipline was wrong, and not because the drift lesson is any less load-bearing.
+
+A reviewer or future maintainer reading this ADR should not infer: "OCP relaxed its alignment rules." The Class A regime is structurally identical to the version that shipped in PR #20. What changed is that the constitution now names the scope of that regime precisely (the class of endpoint for which `cli.js` is the wire authority) instead of implicitly applying it to every endpoint, including ones the regime was never designed for.
+
+## Alternatives considered
+
+**(a) Refuse Class B as a category; close PR #99 and delete `/v1/chat/completions`.** This would resolve the structural ambiguity by enforcing Rule 2 maximally — if `cli.js` doesn't speak OpenAI's protocol, neither does OCP. Rejected: there is an existing user base on the OpenAI-compat surface, the surface is genuinely useful (it is OCP's bridge to non-Claude-Code agents), and deletion would be a load-bearing user-facing breakage in service of a doctrinal point that the constitution was never designed to make. The constitution was a response to the 2026-04-11 forwarding drift, not a charter against any OCP-owned surface.
+
+**(b) Soften Rule 2 to "OCP must not introduce surface area not present in `cli.js` OR not authorized by an ADR."** This is the obvious diff and would unblock PR #99 with the smallest possible textual change. Rejected because it loses the precision that Class A needs. A combined Rule 2 means a Class A reviewer has to read the PR description twice to figure out which authority applies. The Class A/B split makes the question explicit at the PR-template level (the author picks the class) and at the reviewer level (the reviewer opens the appropriate reference). The cost of the split is one new section in `ALIGNMENT.md`; the benefit is no ambiguity in either class.
+
+**(c) Move `/v1/chat/completions` and all OpenAI-compat surface out of OCP into a separate "ocp-openai-shim" repository.** This would cleanly resolve the scope question by moving Class B out of OCP entirely. Rejected as premature: the maintainer is one person, the OpenAI-compat surface today is a single endpoint plus its support, and the operational cost of two repositories (separate releases, separate CI, separate version coordination) exceeds the cost of one constitution with two named classes. If the OpenAI-compat surface ever grows to the size where a separate repo is justified, ADR 0006 is the natural pivot point — at that future date, the carve-out becomes a separation.
+
+**(d) Twelve-ADR back-fill for the existing B.2 inventory before this ADR can merge.** Considered and rejected on cost grounds. Each back-fill ADR would be a short paragraph explaining what an existing endpoint does and why it's allowed; the educational value is low and the merge friction is high (12 PRs through the reviewer gate). The grandfather provision above achieves the same authorization outcome in one paragraph, while still requiring an ADR for any future B.2 endpoint. The trade-off: grandfathered endpoints are not individually documented to ADR-depth. Mitigation: the inventory table in `ALIGNMENT.md` lists every grandfathered endpoint by path and method, so the audit surface remains explicit.

+# Design: SSE Heartbeat on Streaming Path
+
+**Issue:** [#47](https://github.com/dtzp555-max/ocp/issues/47)
+**Date:** 2026-04-25
+**Status:** Draft (awaiting maintainer approval)
+**Target version:** v3.12.0 (minor — new opt-in feature + env var)
+
+---
+
+## Overview
+
+Add an opt-in idle-watchdog heartbeat to OCP's streaming response. When enabled, OCP emits an SSE comment frame (`: keepalive\n\n`) whenever the stream has been idle for a configurable interval. Timer resets on every real frame. Covers both pre-first-byte and mid-stream silent windows. Default **disabled**. Zero behavior change for existing deployments on upgrade.
+
+Companion tweak: `X-Accel-Buffering: no` response header added to both SSE header sites so heartbeats survive nginx-default proxy buffering.
+
+## Motivation
+
+Per [#47](https://github.com/dtzp555-max/ocp/issues/47): when `claude -p` takes a long time to respond (processing large contexts, or executing long tool calls that pause the token stream for 30s–5min), OCP emits no bytes to the downstream client for up to 600s. The caller cannot distinguish "slow but alive" from "hung." A recent incident reported 15 consecutive 600s silent waits cascading into a 2-hour downstream gateway outage.
+
+SSE heartbeats at the application layer let a caller observe liveness without OCP introducing any new client-killing timer.
+
+## Key decisions (with rationale)
+
+Six decisions were fixed during brainstorming. Each is presented as "decision → rationale" so future readers can judge whether a decision is still load-bearing.
+
+### D1. Coverage: whole-stream with idle-watchdog reset-on-byte
+
+A per-request timer starts when SSE headers are written and resets on every real `sendSSE()` call. Heartbeat fires only during genuine idle windows — never during healthy token bursts.
+
+**Rationale.** The `server.mjs:8-10` comment documents Claude tool-use pauses as "30s-5min pauses in the token stream." This means silent windows happen both pre-first-byte AND mid-stream. Covering only one of the two windows means re-opening this issue in three months when a different user reports the uncovered case. The reset-on-byte discipline is a ~2-LOC discipline (`clearTimeout` + `setTimeout` inside `sendSSE`) and is the standard "idle watchdog" pattern.
+
+### D2. Frame format: SSE comment (`: keepalive\n\n`)
+
+**Rationale.** Per SSE spec / MDN, lines starting with `:` are comments and MUST be ignored by conforming parsers. This is the maximally inert shape we can emit. Alternatives considered:
+- `event: ping` named event — Anthropic's own Messages API uses this, but on an OpenAI-compatible surface, downstream clients don't recognize that event name, so risk of client confusion is higher.
+- Empty-delta JSON chunk — parser-safe on OpenAI-compatible clients but burns an event id and is less observably "a heartbeat" in logs.
+
+The known risk with SSE comments is that some SDKs crash on empty comment frames (`openai-go` issue #556). The default-disabled posture (D3) mitigates this: users who opt in can also verify their client tolerates comments. If the comment format turns out to be broken in the wild for common OCP callers, we can add a second format behind `CLAUDE_HEARTBEAT_FORMAT` in a follow-up — **not in this PR**.
+
+### D3. Default disabled
+
+`CLAUDE_HEARTBEAT_INTERVAL=0` (meaning disabled) is the default when the env var is unset. Any positive integer enables at that ms interval.
+
+**Rationale.** Existing deployments see zero byte-shape change on upgrade. Users who have pingvvino's problem set the env var and get the fix. This is a reversible posture: once field evidence shows comment frames are safe across current OCP callers, a future minor can flip the default to `30000`.
+
+### D4. Header relocation: `ensureHeaders()` moves earlier
+
+Currently `ensureHeaders()` is invoked inside the `proc.stdout` handler, so SSE headers are written only on first byte from claude CLI. This PR moves the `ensureHeaders()` call to immediately after successful `spawn()` return.
+
+**Rationale.** You cannot emit SSE frames before sending SSE headers. For heartbeats to cover the pre-first-byte silent window (pingvvino's "processing large contexts" case), headers must be sent earlier. Behavioral consequence: the narrow "spawn succeeded but subprocess erroneously died before any byte" branch — currently a JSON error response — becomes an SSE error event + `[DONE]` + `res.end()`. Pre-spawn errors (before `spawn()`) still return JSON, unchanged. The affected path is rare (claude CLI either spawns or it doesn't).
+
+### D5. Transport-layer buffering hint: `X-Accel-Buffering: no`
+
+Added to both SSE response header sites (real-streaming `ensureHeaders()` and the cache-hit simulated-streaming header write).
+
+**Rationale.** nginx (and many LBs / Cloudflare) default to buffering proxied responses. Without this header, heartbeat bytes may accumulate in an upstream buffer and never reach the client, defeating the feature silently. This header is a nginx-specific hint; other stacks ignore it. 1 line per site, 2 sites total, indistinguishable-from-no-op for stacks that don't use it.
+
+### D6. Observability: single log line per affected request
+
+On the first heartbeat fire within a request, emit a structured log entry (`logEvent("info", "heartbeat_active", { session, intervalMs })`). No log spam for subsequent fires in the same request.
+
+**Rationale.** For a first-mover feature the question "did the heartbeat actually work for that hung request?" needs to be answerable from the existing `/logs` endpoint alone, without external tooling. One line per affected request gives proof-of-life without polluting the log stream during healthy traffic (where the timer resets and never fires).
+
+## Architecture
+
+Single-file change in `server.mjs`. One new helper plus small patches to existing sites.
+
+```
+startHeartbeat(res, intervalMs, sessionId) → { reset(), stop() }
+  if intervalMs <= 0: return no-op handle
+  internal: handle = setTimeout(intervalMs, onFire)
+  onFire():
+    res.write(": keepalive\n\n")
+    if !hasFired: logEvent("info", "heartbeat_active", { session, intervalMs }); hasFired = true
+    handle = setTimeout(intervalMs, onFire)
+  reset(): clearTimeout(handle); handle = setTimeout(intervalMs, onFire)
+  stop():  clearTimeout(handle); handle = null
+```
+
+Handle created once per streaming request. `sendSSE()` calls `heartbeat.reset()` before its `res.write()`. All exit paths call `heartbeat.stop()`.
+
+## Components and LOC budget
+
+| Location | Change | Est LOC |
+|---|---|---|
+| `server.mjs` env block | Parse `CLAUDE_HEARTBEAT_INTERVAL` | 1 |
+| `server.mjs` new `startHeartbeat()` function | Per spec above | 12 |
+| `server.mjs:565-579` `ensureHeaders()` | Add `"X-Accel-Buffering": "no"` to header object | 1 |
+| `server.mjs:~548-554` streaming entry | Move `ensureHeaders()` call to post-spawn; create heartbeat handle | 3 (net) |
+| `server.mjs:669` `sendSSE()` | Accept optional `hb` param; call `hb?.reset()` before `res.write()` | 2 |
+| `server.mjs` streaming exit hooks (proc 'close', proc 'error', req 'close') | Call `hb.stop()` | 3 |
+| `server.mjs:~610-611` pre-first-byte error branch | If headers sent, SSE error + `[DONE]` + `res.end()` instead of JSON | 3 |
+| `server.mjs:1171` cache-hit header write | Add `"X-Accel-Buffering": "no"` | 1 |
+| `README.md` env var table | One new row | 1 |
+| `README.md` new short section | "Streaming heartbeat" paragraph + nginx note | 5 |
+| `CHANGELOG.md` new v3.12.0 entry | Features + Config additions | 4 |
+| `package.json` + `ocp-plugin/package.json` + `ocp-plugin/openclaw.plugin.json` | Version bump 3.11.1 → 3.12.0 | 3 |
+
+**Estimated total: ~40 lines.** This is 5–10 lines over the 25–35 budget set in brainstorming. The overshoot is accounted for by D4 (header relocation + SSE error branch) and D5 (X-Accel-Buffering at two sites). Reviewer may reject if actual code lands materially larger than ~45 lines of server.mjs code excluding docs and version files.
+
+## Data flow (streaming request, heartbeat enabled)
+
+1. Client sends `POST /v1/chat/completions` with `stream=true`.
+2. Cache miss → `callClaudeStreaming()` invoked.
+3. `spawn()` claude subprocess succeeds → `ensureHeaders(res)` writes SSE headers including `X-Accel-Buffering: no`.
+4. `const hb = startHeartbeat(res, HEARTBEAT_INTERVAL, sessionId)` arms the watchdog (no-op if interval is 0).
+5. Watchdog ticks after `HEARTBEAT_INTERVAL` ms of idle. On fire: `: keepalive\n\n` out; first-fire logs once; re-arm.
+6. Every real `sendSSE()` write calls `hb.reset()` — cancels and re-arms timer.
+7. Healthy token bursts → heartbeat never fires.
+8. Tool-use pause → timer elapses → heartbeat fires → client stays alive → re-arm → repeat until next chunk arrives.
+9. On proc 'close' (success / `[DONE]`) / proc 'error' / req 'close' / `CLAUDE_TIMEOUT` kill → `hb.stop()`.
+
+## Error handling
+
+- **Client disconnect mid-heartbeat.** `req.on('close')` fires → `hb.stop()`. Any in-flight write becomes a no-op / emits `'error'` on `res`; existing code already tolerates this.
+- **`CLAUDE_TIMEOUT` (600s) fires mid-request.** Existing timeout handler SIGTERM's subprocess → proc 'close' → `hb.stop()`. This PR does **not** fix the separate issue that the current timeout path does not `res.end()` or emit an SSE error frame; that is documented as a separate issue.
+- **`spawn()` throws synchronously.** Heartbeat never started. Existing JSON error response unchanged.
+- **`spawn()` succeeds, subprocess errors before first byte.** Headers have already been written (per D4). Branch emits an SSE error event + `[DONE]` + `res.end()` instead of a JSON error. Documented behavior change.
+
+## Testing plan
+
+OCP has no unit test framework beyond `test-features.mjs`. Verification is manual + cloud-backed.
+
+### Manual local smoke test
+
+1. Set `CLAUDE_HEARTBEAT_INTERVAL=5000` (5s for easy observation) and start OCP.
+2. Issue a streaming completion with a prompt that triggers a tool-use pause (e.g., ask for a large file read or long reasoning):
+   ```
+   curl -N http://localhost:3456/v1/chat/completions \
+     -H "Authorization: Bearer $OCP_KEY" \
+     -d '{"model":"claude-opus-4-7","stream":true,
+           "messages":[{"role":"user","content":"read the attached 200KB text and summarize"}]}'
+   ```
+3. Confirm `: keepalive` comment lines appear in the raw response during the pause, at ~5s cadence.
+4. Confirm `/logs` shows exactly one `heartbeat_active` entry for the request.
+5. With `CLAUDE_HEARTBEAT_INTERVAL=0` (default), confirm no heartbeats and no log line.
+
+### Cloud-backed test run (pre-push, required)
+
+Per project feedback, tests must pass before any push to the public repo. Options, in preference order:
+
+1. **GitHub Actions** — add a temporary smoke workflow (or piggyback on an existing one) that runs `test-features.mjs` against a sandboxed claude mock. Not viable if `test-features.mjs` requires a real claude CLI auth.
+2. **Remote Linux test host via cc-chat handoff** — push feature branch, instruct a cloud machine with claude CLI installed to run the manual steps above, capture output, return verdict via cc-chat.
+3. **Docker/compose locally** — if the maintainer has Docker available, `docker-compose.yml` is present and can be extended.
+
+The implementation subagent and the reviewer subagent MUST include the chosen verification evidence in the PR body (command + output excerpt, sanitized of any identifiers) before the PR is opened for merge review.
+
+### Downstream-parser compatibility
+
+Before merging, verify at least one real downstream client (OCP's own `ocp-connect`, plus — if feasible — the current OpenClaw gateway) does not crash on comment frames. If a target client crashes, either (a) adjust the default to 0 and document the incompatibility, or (b) scope a follow-up PR for `CLAUDE_HEARTBEAT_FORMAT=empty-delta` as an alternative.
+
+## Privacy preflight (for public-repo push)
+
+Before `gh pr create` or any `git push` to `dtzp555-max/ocp`, run the following scan on the full diff (`git diff origin/main...HEAD`):
+
+1. **Use OCP's PR template privacy self-check** — the `.github/PULL_REQUEST_TEMPLATE.md` Privacy self-check section is the canonical list. Fill every checkbox.
+2. **Run `.gitleaks.toml` via gitleaks if available.**
+3. **Manual grep on the diff** for these patterns (sanitize any hits before commit):
+   - Personal names in any language (check commit-author trailers especially — `Co-Authored-By` lines have leaked names before).
+   - Email addresses beyond automated placeholders (`noreply@*`).
+   - Local paths like `/Users/<name>/`, `/home/<name>/`, `C:\Users\<name>\` — replace with `$HOME/` or `~/`.
+   - Machine hostnames — use role-based names or generic descriptors.
+   - IPs, internal URLs, tailnet names.
+4. **Log samples and test output** pasted into spec / README / CHANGELOG / PR body must be sanitized pre-paste, not pre-push. This spec doc itself was drafted under this discipline.
+
+Historical reference: PR #43 / postmortem #44 (2026-04-22) scrubbed a prior leak and established the current apparatus. The user has explicitly flagged this as a scar to avoid re-treading for this PR.
+
+## Scope lock (out of scope)
+
+- `server.mjs:480-489` `CLAUDE_TIMEOUT` dangling-client behavior (no `res.end()` / no SSE error frame on timeout kill) — **will be filed as a separate issue** before this PR opens.
+- Issue #41 (handleSessionFailure deletes on resume only) — separate.
+- Issue #42 (SESSION_TTL and `lastUsed` interaction) — separate.
+- Any new first-byte / idle / adaptive-tier timeout logic — explicitly forbidden per the v3.3 lesson (`server.mjs:8-11`, commit 3843ec8).
+- Non-streaming chat path — no HTTP-level fix possible per [#47](https://github.com/dtzp555-max/ocp/issues/47)'s own conclusion.
+- Named-event format (`event: ping`) or empty-delta JSON chunk variants — possible follow-up PR if field evidence shows comment frames break real clients.
+- Changes to `CLAUDE_TIMEOUT` default — unchanged (stays 600s).
+- Circuit breaker revival — explicitly forbidden.
+
+## ALIGNMENT.md disposition
+
+`cli.js` does not itself emit SSE heartbeat frames — claude CLI speaks newline-delimited JSON to stdout, not SSE. SSE is an OCP-owned translation layer. Per `ALIGNMENT.md` Rule 2 / `AGENTS.md` ("OCP forwards, observes, and multiplexes traffic that cli.js already emits"): heartbeats are a translation-layer response-shaping concern, not a new endpoint and not a behavior mimicry. The PR body will state this explicitly in the `cli.js` citation checkbox and reference this design doc.
+
+## IDR (Iron Rule 11) disposition
+
+Single PR. Scope is one feature (SSE heartbeat) × one layer (streaming response formatting) × one severity (minor opt-in addition). Release-kit companion files (version bump, CHANGELOG, README) are bundled with the code change per the explicit Iron Rule 11 example ("版本 bump 相关的小改动 + README + CHANGELOG 可以同 PR"). The separate filings for the dangling-client bug (`server.mjs:480-489`) and any follow-up heartbeat format variants are IDR-compliant — each lands as its own PR.

+# Design: Response Cache Upgrade (Per-Key Isolation, cache_control Bypass, Chunked Stream Replay, Singleflight)
+
+**Date:** 2026-05-07
+**Status:** Draft (awaiting maintainer approval)
+**Target version:** v3.13.0 (minor — internal correctness/concurrency improvements; no new public env vars or endpoints)
+**Driving ADR:** [ADR 0005 — No Multi-Provider](../../adr/0005-no-multi-provider.md), decision §3 ("Cache improvements are in scope")
+
+---
+
+## Overview
+
+OCP already has a response cache (`keys.mjs:296` `cacheHash` / `keys.mjs:311` `getCachedResponse` / `keys.mjs:324` `setCachedResponse`), wired into the proxy core at `server.mjs:1220` (non-streaming path read), `server.mjs:1227` (cache-hit-on-streaming-request replay), and `server.mjs:683` (streaming write-back). Today it has four functional gaps. This PR pair closes all four, in two minimum-reviewable units, **without changing the public API surface**.
+
+| Gap | Impact today | Fix lands in |
+|---|---|---|
+| All keys share one cache pool | Key A's cache hit can leak Key B's prompt response | PR-A |
+| Anthropic `cache_control` markers not detected | OCP cache may interfere with Anthropic prompt caching that the user explicitly requested | PR-A |
+| Stream cache hit replays whole content in one SSE chunk | Downstream renders all-at-once; some SDKs misbehave on huge single deltas | PR-A |
+| Concurrent identical cache misses all spawn `cli.js` independently | Cache stampede: N requests → N spawns → N billable calls | PR-B |
+
+---
+
+## Constitutional alignment (ALIGNMENT.md)
+
+**`cli.js` does not perform response caching at the proxy layer.** The OCP response cache is a value-add operation that exists only inside OCP, between the wire (clients ↔ OCP) and the spawn (OCP ↔ `cli.js`). It does not introduce, rename, or alter any endpoint, header, request field, or response field that `cli.js` emits or expects. Cache hits return content byte-identical to what `cli.js` returned on the original miss, with the same `chat.completion` / `chat.completion.chunk` shape — **no client-observable wire shape change**.
+
+This PR pair extends the existing cache (introduced in earlier commits) without expanding its surface. No new endpoints. No new headers. No new env vars exposed publicly (we add internal counters readable via the existing `/cache/stats` endpoint, but the response shape only gains numeric fields, not new structural fields).
+
+Per Rule 1 / Rule 5: every commit body in this PR pair will state the absence of `cli.js` reference explicitly and justify scope under Rule 2's value-add carve-out for non-wire-affecting proxy operations.
+
+---
+
+## Key decisions (with rationale)
+
+### D1. Per-key isolation via hash input, not schema column
+
+`cacheHash` gains an optional `keyId` input. Distinct `keyId` values produce distinct hashes for the same prompt, so SQLite-level isolation falls out for free without a schema change.
+
+**Rationale.** Adding a `key_id` column to `response_cache` requires either (a) dropping the existing `hash UNIQUE` index and replacing with a composite `(hash, key_id) UNIQUE`, which SQLite cannot do via plain `ALTER TABLE` and would require a table-rebuild migration, or (b) tolerating duplicate `hash` rows, which contradicts the existing schema comment and breaks `setCachedResponse`'s `ON CONFLICT(hash)` upsert clause.
+
+The hash-input approach is reversible (we can switch to a schema column later if analytics across keys becomes a real need) and zero-risk on the SQL plane. The trade-off — losing the ability to query "which keys have cached this prompt?" — has no current consumer.
+
+**Hash input format.** `cacheHash` prepends a version tag and key tag before the existing inputs:
+
+```
+v2|k:<keyId or "anon">|<model>|...rest as today
+```
+
+The `v2` prefix means existing v1-format rows in the cache table no longer hash-match any new request. They are abandoned, not deleted; the existing TTL-based `clearCache(CACHE_TTL)` cleanup interval at `server.mjs:185` reaps them within one TTL window. **No migration step is needed.** This is acceptable because the cache is by definition ephemeral and best-effort.
+
+**Anonymous fallback.** When the request has no authenticated key (`req._authKeyId === undefined`), `keyId` is `"anon"`. Anonymous-mode users (PROXY_ANONYMOUS_KEY or no auth) share one anonymous pool, which preserves the only legitimate today-multi-user use case (a household running OCP without per-user keys). If this becomes a problem we can add per-IP scoping later, but anonymous-pool sharing is acceptable for v1 because anonymous mode is fundamentally a trust-everyone-on-LAN posture.
+
+### D2. `cache_control` bypass: detect anywhere, skip OCP cache entirely
+
+If any element in `messages` (top-level or nested in `content` arrays) carries a `cache_control` field, OCP sets `req._cacheHash = null` and skips both lookup and write-back.
+
+**Rationale.** Anthropic's [prompt caching](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching) is opt-in by client-side annotation. A user who annotates `cache_control: { type: "ephemeral" }` is explicitly requesting that *Anthropic's* cache serve the call (and is paying the reduced cache-read pricing). Layering OCP's response cache on top in this case is wrong on two counts:
+
+1. The user's intent is "cache at provider, not at proxy." OCP overruling that intent silently is the same drift family as the 2026-04-11 incident — proxy invents behavior the upstream surface doesn't request.
+2. OCP cache hits would make `usage.cache_read_input_tokens` (the client-observable signal that prompt caching worked) appear inconsistent — sometimes present, sometimes absent — depending on whether OCP cached.
+
+Detection is purely structural: walk `messages`, for each `m` check `m.cache_control` (rare top-level form) and if `m.content` is an array, check each part. No semantic interpretation; if the field is present, we bypass.
+
+**Implementation site.** A small helper `hasCacheControl(messages)` exported from `keys.mjs`, called in `handleChatCompletions` immediately before the existing `cacheHash` call. If it returns true, we skip the cache-lookup branch entirely.
+
+### D3. Chunked stream replay (80 chars/chunk, no artificial delay)
+
+Today's cache-hit-on-streaming-request branch (`server.mjs:1227–1237`) sends the entire cached content in a single `delta.content` chunk. This works for spec-compliant SSE clients but visibly degrades the UX (no incremental render) and has tripped at least one buggy SDK in the wild that assumes deltas are small.
+
+The fix splits cached content into ~80-character substrings, each sent as a separate `chat.completion.chunk` SSE event. **No artificial delay between chunks** — they ship as fast as `res.write` accepts. This preserves OCP's "ship as fast as possible" disposition; we are simulating *the chunk shape* of streaming, not the *latency*.
+
+**Why 80 chars?** Compromise: small enough that even a multi-paragraph cached response yields >5 chunks (visible incremental render), large enough that even a 4 KB response only produces 50 chunks (not 4000 single-char events). Tunable later via internal constant; not exposed as env var per scope-creep avoidance.
+
+**Boundary safety.** UTF-8 multibyte characters: we slice by `Array.from(content)` (so each iteration step is a full code point) and group every 80 code points. This avoids producing invalid UTF-8 mid-character.
+
+### D4. Singleflight stampede protection: in-process Map, all-or-nothing failure
+
+`keys.mjs` exports `singleflight(hash, fn)`. An in-memory `Map<hash, Promise>` deduplicates concurrent identical cache-miss flows. The first request executes `fn()`; concurrent requests with the same hash receive the same promise. When the promise settles (resolve or reject), the map entry is deleted.
+
+**Rationale (single-process scope).** OCP runs as a single Node.js process per host. A `Map` is sufficient. Adding Redis or another shared store would be the start of a multi-instance evolution, which is out of scope per ADR 0005 (OCP is a personal power tool, not a horizontally-scaled SaaS).
+
+**All-or-nothing failure semantics.** When the leader's `fn()` rejects, all followers receive the same rejection. The alternative — letting followers retry independently after a leader failure — risks N retries of an already-broken upstream, which is exactly what stampede protection was meant to prevent. Followers can retry at the *next* request, with idle backoff handled by the client. This matches Go's `golang.org/x/sync/singleflight` reference behavior.
+
+**Streaming caveat.** Singleflight wraps the *non-streaming* code path only in PR-B. For streaming, deduplicating concurrent identical streaming requests is materially harder (we'd need to fan out one upstream stream to N downstream connections in real time, with backpressure). It's also a less common case (cache stampedes typically come from non-streaming batch jobs hitting the proxy in parallel). Streaming dedup is **explicitly out of scope** for this PR pair; leave a TODO comment in `callClaudeStreaming` for a future ticket.
+
+**Map size unboundedness.** In normal operation the map is empty most of the time (entries delete on Promise settlement). Pathological case: an upstream call that hangs forever leaks one Map entry per stuck request. The existing `TIMEOUT` guard on `callClaude` (server.mjs spawn timeout) bounds this — the Promise will reject (timeout) within `TIMEOUT` ms, and the entry clears. No additional sweep needed.
+
+---
+
+## PR boundaries
+
+### PR-A — Foundation (D1 + D2 + D3)
+
+**Files touched:**
+- `keys.mjs`: extend `cacheHash` with optional `keyId`/version prefix; add `hasCacheControl(messages)` helper
+- `server.mjs`: pass `req._authKeyId` to `cacheHash`; check `hasCacheControl` and bypass; chunk cache-hit replay at line 1227–1237
+- `test-features.mjs`: add cases for keyId isolation, cache_control bypass, chunked replay shape
+
+**LOC budget:** ~80 production + ~50 test
+**Risk:** Low — all changes are additive or guard-clause; existing cache behavior preserved when `keyId` defaults to "anon" and no `cache_control` present.
+**Backward compat:** v1-format hashes naturally orphan; TTL cleanup reaps within one window; no migration script.
+
+### PR-B — Concurrency (D4)
+
+**Files touched:**
+- `keys.mjs`: add `singleflight(hash, fn)` and `getInflightStats()` exports
+- `server.mjs`: wrap non-streaming cache-miss path through `singleflight`; add inflight count to `/cache/stats` response
+- `test-features.mjs`: add concurrent-request test that asserts only 1 spawn occurs for N=10 simultaneous identical requests
+
+**LOC budget:** ~70 production + ~40 test
+**Risk:** Medium — concurrency code is harder to reason about; mitigation is an explicit test case for the dedup behavior.
+**Streaming explicitly out of scope:** TODO comment placed in `callClaudeStreaming` for follow-up ticket.
+
+---
+
+## Testing strategy
+
+**Unit-ish (in `test-features.mjs`):**
+1. `cacheHash` with two different `keyId` values → different hashes
+2. `cacheHash` v2 prefix present in output (sanity check)
+3. `hasCacheControl` returns true for top-level `cache_control` and for nested in `content[]`
+4. `hasCacheControl` returns false for benign messages
+5. Chunked replay: cached "abcdefgh..." (160 chars) produces 2 deltas
+
+**Integration (manual smoke before merge):**
+1. Set `CLAUDE_CACHE_TTL=60000`; create key A and key B; identical prompt from each → both spawn fresh; second-call from same key → cache hit
+2. Send a message with `cache_control` annotation → OCP logs `cache_skipped: cache_control_present`; no cache write
+3. Streaming cache hit visibly produces multiple SSE deltas (`curl -N | grep "data: "` shows >1 lines)
+
+**Concurrent (PR-B only):**
+1. Spawn 10 simultaneous identical non-streaming requests; assert (via `/cache/stats` inflight peak or via a process spawn counter) only 1 `cli.js` spawn occurred
+
+---
+
+## Out of scope (deliberately deferred)
+
+- **Streaming singleflight** — see D4 streaming caveat. TODO in code.
+- **Semantic cache** (embedding-based near-match) — needs an embedding provider + vector index. Punt to v3.14+ if there's user demand.
+- **Cross-process cache** (Redis backend) — violates ADR 0005's "personal power tool" posture.
+- **Cache versioning by model ID hash** — model upgrades currently invalidate cache organically because model is in the hash; if Anthropic ever silently changes a model's behavior without a model ID bump, that's a separate alignment problem.
+- **Per-key cache TTL override** — single global TTL (existing `CLAUDE_CACHE_TTL`) is fine; per-key TTL is a knob no one has asked for.
+
+---
+
+## Rollback plan
+
+If either PR introduces a regression, the rollback is a clean git revert. The cache layer is opt-in (default `CLAUDE_CACHE_TTL=0` = disabled), so users who never enabled the cache are unaffected by any cache-layer regression. Users who *had* enabled the cache lose only ephemeral state on revert. No persistent on-disk state is reshaped by this PR pair (we explicitly avoid schema migrations per D1 rationale).

-# openclaw-claude-proxy v2.3.0
-
-Use your **Claude Pro / Max** subscription as an **OpenAI-compatible local endpoint**.
-
-`openclaw-claude-proxy` accepts OpenAI-style chat completion requests, then runs them through the local `claude` CLI. That means tools which only know how to talk to an OpenAI API can still use Claude models through a local base URL.
-
-## Why v2 matters
-
-v2 is not just a bugfix release. It changes the runtime model:
-
-- **On-demand spawning** instead of fragile warm pools
-- **Session resume** support for multi-turn conversations
-- **Faster fallback** with first-byte timeout + lower default request timeout
-- **Full tool access** via configurable allowed tools
-- **MCP config + system prompt pass-through**
-- **Health / sessions / diagnostics endpoints**
-- **Safe coexistence with Claude Code channel / interactive mode**
-
-## The short pitch
-
-If Claude's new channel workflow feels useful, OCP v2 now covers the same practical ground for many local agent/tooling setups:
-
-- multi-turn continuity
-- tool-enabled Claude runs
-- local orchestration
-- stable process isolation
-- coexistence with your normal Claude Code workflow
-
-And it adds a few advantages that channel users usually still want:
-
-- **OpenAI-compatible HTTP API** for existing tools
-- **Works with OpenClaw, Cursor, Continue, Open WebUI, LangChain, and anything with custom base URL support**
-- **Explicit health checks and diagnostics**
-- **Model/provider failover can happen outside Claude itself**
-- **No lock-in to a single client UX**
-
-## Coexistence with Claude Code channel
-
-This is the important part: **OCP v2 does not replace Claude Code channel, and it does not need to. They can coexist on the same machine.**
-
-### Claude Code channel / interactive mode
-- persistent interactive workflow
-- MCP protocol / in-process experience
-- great when you are directly driving Claude Code
-
-### OCP v2
-- local HTTP server on `localhost`
-- OpenAI-compatible API surface
-- per-request `claude -p` execution with session resume when you want continuity
-- ideal for external tools, routers, orchestrators, OpenClaw providers, and local automation
-
-### Practical takeaway
-Use both:
-- use **Claude Code channel** when you want Claude's native interactive workflow
-- use **OCP v2** when another app expects an OpenAI-style API but you still want to use Claude
-
-They solve adjacent problems, not identical ones.
-
-## Unique advantages of OCP v2
-
-1. **API compatibility**
-   - Drop into tools that already support OpenAI-compatible endpoints.
-   - No need to wait for each tool to add native Claude channel support.
-
-2. **Routing freedom**
-   - Put OCP behind OpenClaw or another router.
-   - Mix Claude with fallback providers outside the Claude client itself.
-
-3. **Operational visibility**
-   - `/health`, `/sessions`, recent errors, auth state, resolved binary path, timeout config.
-   - Much easier to debug than a black-box local integration.
-
-4. **Safer runtime model**
-   - v2 removes the old pre-spawn pool crash loop.
-   - No stale workers, no degraded warm pool states, fewer hidden failure modes.
-
-5. **Configurable tools and behavior**
-   - allowed tools
-   - skip permissions mode
-   - system prompt append
-   - MCP config passthrough
-   - session TTL
-   - concurrency limits
-
-## Install
-
-```bash
-git clone https://github.com/dtzp555-max/openclaw-claude-proxy
-cd openclaw-claude-proxy
-npm install
-node server.mjs
-```
-
-Default base URL:
-
-```text
-http://127.0.0.1:3456/v1
-```
-
-## Quick OpenAI-compatible config
-
-```json
-{
-  "baseURL": "http://127.0.0.1:3456/v1",
-  "apiKey": "anything"
-}
-```
-
-If `PROXY_API_KEY` is unset, auth is disabled. If you set it, pass it as a Bearer token.
-
-## Environment variables
-
-| Variable | Default | Purpose |
-|---|---:|---|
-| `CLAUDE_PROXY_PORT` | `3456` | Listen port |
-| `CLAUDE_BIN` | auto-detect | Claude CLI binary path |
-| `CLAUDE_TIMEOUT` | `120000` | Overall per-request timeout |
-| `CLAUDE_FIRST_BYTE_TIMEOUT` | `30000` | Abort if Claude produces no stdout quickly |
-| `CLAUDE_ALLOWED_TOOLS` | expanded set | Comma-separated allowed tools |
-| `CLAUDE_SKIP_PERMISSIONS` | `false` | Bypass permission checks |
-| `CLAUDE_SYSTEM_PROMPT` | unset | Append a system prompt to every request |
-| `CLAUDE_MCP_CONFIG` | unset | Path to MCP config JSON |
-| `CLAUDE_SESSION_TTL` | `3600000` | Session TTL |
-| `CLAUDE_MAX_CONCURRENT` | `5` | Max concurrent Claude processes |

-- clarified v2 positioning and coexistence story in docs
-- officially documents faster fallback defaults
-- recommends OCP v2 as the API bridge layer for Claude-powered tools
-
-### v2.2.0
-- first-byte timeout
-- reduced default timeout for faster fallback
-
-### v2.0.0
-- on-demand architecture
-- session management
-- full tool access
-- MCP + system prompt passthrough
-- concurrency control
-- coexistence with Claude Code interactive mode
-
-## When to use OCP v2 vs Claude channel
-
-Choose **OCP v2** when:
-- your app only supports OpenAI-compatible endpoints
-- you want routing / failover outside Claude
-- you want explicit health checks and local diagnostics
-- you want Claude available to multiple local tools through one endpoint
-
-Choose **Claude channel** when:
-- you are primarily living inside Claude Code itself
-- you want Claude's native interactive workflow directly
-
-Use **both together** when you want the best of both worlds.
-
----
-
-If you already pay for Claude Pro or Max, OCP v2 turns that subscription into a practical local API bridge for the rest of your tooling stack.

-/**
- * openclaw-claude-proxy v2.4.0 — OpenAI-compatible proxy for Claude CLI
- *
- * Translates OpenAI chat/completions requests into `claude -p` CLI calls,
- * letting you use your Claude Pro/Max subscription as an OpenClaw model provider.
- *
- * v2.4.0:
- *   - Per-model circuit breaker: consecutive timeouts temporarily mark a model as degraded
- *   - Adaptive first-byte timeout: scales by model tier + prompt size
- *   - Structured JSON logging for key events (easier to parse/alert on)
- *   - On-demand spawning (no pool), session management, full tool access
- *
- * Env vars:
- *   CLAUDE_PROXY_PORT        — listen port (default: 3456)
- *   CLAUDE_BIN               — path to claude binary (default: auto-detect)
- *   CLAUDE_TIMEOUT           — per-request timeout in ms (default: 120000)
- *   CLAUDE_FIRST_BYTE_TIMEOUT — base first-byte timeout in ms (default: 45000)
- *   CLAUDE_ALLOWED_TOOLS     — comma-separated tools to allow (default: expanded set)
- *   CLAUDE_SKIP_PERMISSIONS  — "true" to bypass all permission checks (default: false)
- *   CLAUDE_SYSTEM_PROMPT     — system prompt appended to all requests
- *   CLAUDE_MCP_CONFIG        — path to MCP server config JSON file
- *   CLAUDE_SESSION_TTL       — session TTL in ms (default: 3600000 = 1h)
- *   CLAUDE_MAX_CONCURRENT    — max concurrent claude processes (default: 5)
- *   CLAUDE_BREAKER_THRESHOLD — consecutive timeouts before circuit opens (default: 3)
- *   CLAUDE_BREAKER_COOLDOWN  — ms to wait before retrying after circuit opens (default: 60000)
- *   PROXY_API_KEY            — Bearer token for API auth (optional)
