1b02f181fa refactor: extract isLoopbackBind to lib/net.mjs (#125) (#127)
Follow-up cleanup from #115's review. isLoopbackBind was defined in server.mjs and
copy-pasted into test-features.mjs (with a "keep in sync" comment, because importing
server.mjs would run server.listen()). Extracted to a new importable lib/net.mjs;
server.mjs and the test now import the one definition, removing the drift surface.

Pure refactor — the function body is byte-identical to the prior server.mjs version,
the TUI LAN-gate call site is unchanged, and the 8 isLoopbackBind truth-table tests now
exercise the real shared function. 181 tests pass.

ALIGNMENT.md: touches server.mjs but adds/removes no operation — it relocates an existing
(#115) helper into a module. cli.js citation N/A under Rule 2.

Independent fresh-context reviewer (opus): APPROVE (Iron Rule 10) — byte-identical body,
exactly one definition, wiring + scope correct, no test dropped, scope clean.

Closes #125.

aa1c65beb1 fix: TUI hardening — non-loopback LAN gate + assert cc_entrypoint (#115) (#122)
Two TUI-mode findings from the 2026-05-31 audit (ADR 0007):

1. The fail-loud LAN gate refused TUI boot only when CLAUDE_BIND === "0.0.0.0",
   but binding to a concrete LAN IP, a Tailscale 100.x address, or IPv6 :: is
   equally network-exposed and slipped through — letting any reachable peer drive
   the operator's full-filesystem claude session. New isLoopbackBind() treats only
   127.0.0.0/8 / ::1 / localhost / ::ffff:127.0.0.1 as safe; the gate now trips on
   any non-loopback bind (OCP_TUI_ALLOW_LAN=1 escape hatch retained).

2. verifyEntrypoint() was implemented and unit-tested but never wired: readTuiTranscript
   discarded the events and returned only text, so a silent degrade to the metered
   sdk-cli (Agent SDK) billing pool — which still returns text but costs money — went
   undetected. readTuiTranscript now returns { text, entrypoint }; runTuiTurn passes it
   through; callClaudeTui logs a "tui_entrypoint_mismatch" warning when configured cli
   mode yields a non-cli entrypoint (including null/unverified). callClaudeTui still
   returns Promise<string>, so singleflight/cache/completion downstream is unchanged.

ALIGNMENT.md: TUI is a proxy-side execution-mode bridge (ADR 0007); this adds a local
bind classifier (startup gate) + a non-fatal log assertion of an existing classification
— no Anthropic operation forwarded, so a cli.js citation is N/A under Rule 2. No
blacklisted tokens or port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10) — verified
isLoopbackBind via truth table (no exposed address misclassified as loopback — the
dangerous direction), the full string→{text,entrypoint} contract ripple across all
callers (Promise<string> preserved), the mismatch logic (warns on sdk-cli AND null in
cli mode, silent for auto/off, non-fatal), and ALIGNMENT N/A via a fetch/header grep.
Minors are process-only (this commit body; a future lib/ extraction of the test-mirrored
helper). npm test → 181 passed, 0 failed.

Closes #115.

879b40fe93 fix: escape dashboard DB-sourced values + validate key names (#114) (#121)
The dashboard built table rows via template-literal innerHTML, interpolating
DB-sourced strings (key names, usage rows) with no HTML escaping, and an
onclick="revokeKeyUI('${k.name}')" sink a single quote could break out of. Key
names were unvalidated at creation. Admin-gated (self-XSS today), but a real
unescaped-sink gap that becomes cross-user if key creation is ever delegated.

- dashboard.html: added escapeHtml() and applied it to every DB/string-sourced
  interpolation in refreshUsage and refreshKeys (key_name, name, keyPreview,
  created_at, last_request, model). Replaced the inline-onclick revoke button with
  a data-revoke attribute + addEventListener, so a name can never break out into an
  event-handler string. (model is attacker-pickable via the request body, so its
  escaping is the load-bearing one.)
- server.mjs: POST /api/keys now rejects names not matching /^[A-Za-z0-9 ._-]{1,64}$/
  before createKey() — defense-in-depth so a <script>/quote name can never reach the
  DB. Creation-only; existing keys unaffected; the default key-${Date.now()} passes.

Noted (out of scope, optional follow-up): the status/plan summary cards render
trusted server/Anthropic-upstream values unescaped — non-user-controlled, so not part
of this stored-XSS fix.

ALIGNMENT.md: the server.mjs change is proxy-policy input validation with no Anthropic
operation forwarded, so a cli.js citation is N/A under Rule 2. No blacklisted tokens or
port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10) — verified
escapeHtml correctness, full sink coverage (incl. the attacker-pickable model field and
the data-revoke attribute), revoke round-trip via getAttribute, the anchored/bounded
key-name regex running before createKey, and that createKey has no other unvalidated
caller. Both minors non-blocking (trusted status-card escaping; this commit-body note).

Closes #114.

4a7d79c330 fix: record OAuth-host verification + models.json SPOT for usage-probe/default (#112) (#119)
Three alignment/SPOT findings from the 2026-05-31 audit:

1. The OAuth token-refresh host (platform.claude.com/v1/oauth/token, a Class A
   surface) was introduced in the 2026-04-11 drift commit and had no verification
   record. Verified against the compiled cli.js (claude.exe v2.1.154) via `strings`:
   OAUTH_TOKEN_URL and OAUTH_CLIENT_ID both appear in the binary byte-for-byte (in
   the same `prod` config object), and the legacy host console.anthropic.com/v1/oauth
   is absent (0 hits). Recorded this as an inline ALIGNMENT citation comment above the
   constants. No live OAuth probe was run — a refresh-token grant would rotate the
   operator's real credentials; the strings-on-binary evidence is decisive.
   (cli.js: verified against compiled claude.exe v2.1.154, 2026-05-31.)

2. fetchUsageFromApi() hardcoded the haiku model ID; now derives from
   modelsConfig.aliases.haiku (ADR 0003 SPOT). Prevents a silent /usage break on a
   future haiku ID bump.

3. [P3] The default request model hardcoded the sonnet ID; now derives from
   modelsConfig.aliases.sonnet (ADR 0003 SPOT).

Both SPOT values are byte-identical to the literals they replace today, so zero
behavior change — only drift-resistance. The alignment.yml blacklist pin for the
wrong-host variant was deliberately NOT included here: extending the blacklist is a
governance-layer change (alignment.yml inline policy) and belongs in its own PR.

ALIGNMENT.md: finding 1 IS the verification (cli.js citation recorded inline);
findings 2-3 are SPOT hygiene that forward no new operation. No blacklisted tokens or
port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus) INDEPENDENTLY re-ran `strings` on the binary
and confirmed the host/client_id present and the legacy host absent — APPROVE (Iron
Rule 10; alignment hard-requirement #3 satisfied).

Closes #112.

c3b1f32c86 fix: error-output sanitization + process-lifecycle hardening (#111) (#118)
Four findings from the 2026-05-31 audit (3×P2 + 1×P3), all in the error/process
lifecycle layer:

1. sanitizeError() helper — streaming error paths sent raw claude error_message /
   stderr to the client, leaking home-dir / credential-file paths that the
   non-streaming path already redacted. Factored the path-strip regex into one
   helper and applied it at all 9 client-facing jsonResponse/sendSSE error emits;
   de-duped the 3 pre-existing inline .replace() sites. Operator-log calls
   (logEvent/trackError) and admin-gated endpoints left raw by design.

2. res.on("close") SIGKILL escalation — a client disconnect sent only SIGTERM; a
   SIGTERM-resistant child held its concurrency slot until the request timeout
   (narrow #37 on the hottest exit path). Now escalates to SIGKILL 5s after SIGTERM,
   cleared on proc exit. Per review: gated on the child still being alive
   (exitCode===null && signalCode===null) so the normal-success close no longer
   fires a spurious SIGTERM or leaks the 5s timer; killTimer.unref() so a genuine
   disconnect timer never delays graceful shutdown.

3. Per-key quota TOCTOU — documented as best-effort/eventually-consistent (inline
   comment + README note): concurrent requests at the boundary can overshoot by up
   to MAX_CONCURRENT and cache hits are uncounted. Chose documentation over an
   in-flight counter to avoid a decrement-on-all-paths liability (the #37 class) on
   a low-blast-radius internal family rate-limiter — not a payment boundary.

4. [P3] overallTimer cleared on semantic completion — the request timer was cleared
   only on proc exit, so a streamed response that res.end()'d before the child
   exited could record a spurious post-success timeout. New clearOverallTimer()
   (clears the timer ONLY, never touches the `cleaned` slot-accounting flag — no
   slot leak) is called in the streaming stop-success path; cleanup() on exit still
   clears it idempotently and decrements the slot.

ALIGNMENT.md: error-shaping / process-lifecycle / rate-limit documentation forward
no Anthropic operation, so a cli.js citation is N/A under Rule 2. No blacklisted
tokens or port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10) — the
two critical concerns (clearOverallTimer slot-leak class, SIGKILL double-kill) were
verified clean; MINOR #1 (kill-timer leak on success path) folded in; MINOR #2
(pre-existing regex over-redaction of ratios/URLs) left as out-of-scope.

Closes #111.

4458490caa fix: request validation + OpenAI-compat correctness (#110) (#117)
Three correctness/compat defects on the request path:

1. Non-array `messages` (e.g. {"messages":"x"}) passed the `!messages?.length`
   guard but threw in `messages.reduce(...)`; since the handler runs without
   await, the rejection silently hung the client until socket timeout. Now
   guarded with `Array.isArray(messages) && length>0` → 400 invalid_request_error,
   placed before the first use of `messages`.

2. OpenAI array `content` ([{type:"text",text},{type:"image_url",...}]) was
   JSON.stringify'd into the prompt as literal noise. New `contentToText()` helper
   flattens text parts and replaces non-text parts with a placeholder; used in
   messagesToPrompt, extractSystemPrompt, and all promptChars char-count sites
   (zero `JSON.stringify(m.content)` remain).

3. A streamed upstream error arriving after eager SSE headers emitted a bare
   finish_reason:"stop" + [DONE] — byte-identical to a successful empty completion.
   Both streaming error paths (the parsed.error result branch AND the non-zero-exit
   close-handler branch — the latter folded in per reviewer) now emit an SSE
   `data:{"error":{...}}` frame so clients can distinguish failure from empty.

Error-text sanitization across all emit sites is intentionally deferred to #110's
sibling issue #111 (security layer).

ALIGNMENT.md: these are OpenAI-compat shim + input-validation behaviors; OCP does
not forward, add, or alter any Anthropic API operation here (cli.js does not speak
the OpenAI wire format), so a cli.js citation is N/A under Rule 2. No blacklisted
tokens or port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10) —
the close-handler sibling fold-in addresses MINOR #1; this commit body addresses
MINOR #2.

Closes #110.

36be723198 fix(security): gate /health anonymousKey behind opt-in PROXY_ADVERTISE_ANON_KEY (#109) (#116)
/health is an unauthenticated, LAN-reachable endpoint that returned the live
anonymous bearer key (anonymousKey: PROXY_ANONYMOUS_KEY). Any device that could
reach the port harvested a working, quota-spending credential (P0).

The anonymousKey field is now included only when the caller is localhost (already
fully trusted by the auth path, via the unspoofable req.socket.remoteAddress) OR
the admin explicitly opts in with the new PROXY_ADVERTISE_ANON_KEY=1 env var
(default off). ocp-connect's absent-field fallback (interactive --key / anonymous
access) is unchanged — comment-only update there.

ALIGNMENT.md: this gates an OCP proxy-policy field in /health; it does NOT forward,
add, or alter any Anthropic API operation, so a cli.js citation is N/A under Rule 2.
No blacklisted tokens introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10).

Closes #109.

05a984df89 fix: OCP code-audit P1+P2 hardening (crash bugs + multi-tenant gates) (#106)
* fix(daemon): P1-1 guard proc.stdin against EPIPE crash

In spawnClaudeProcess, attach an error listener on proc.stdin BEFORE
the write/end calls so an EPIPE (child closed stdin mid-write) is
swallowed and logged rather than thrown as an unhandled exception.

The existing proc.on("error") listener is on the ChildProcess object,
NOT on the stdin Writable — it does not catch stdin write errors.

Hardening per OCP code audit; entry-surface contract unchanged for
single-user default path.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(tui): P1-3 remove tool_use from isTerminalLine; only turn_duration is terminal

In interactive TUI mode, stop_reason=tool_use does NOT mean the turn is
complete. Claude handles the tool call internally and continues generating —
the transcript advances to another assistant entry. Treating tool_use as
terminal truncated tool-using turns mid-flight.

Only {type:"system", subtype:"turn_duration"} is the authoritative
completion marker (claude CLI v2.1.157+ interactive session transcript).

Updated two unit tests that previously asserted tool_use → true; they now
assert false (the correct behaviour). The real-fixture terminal detection
test is unaffected because the fixture uses turn_duration.

Hardening per OCP code audit; TUI path behaviour fix.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(tui): P2-5 add -l (literal) flag to send-keys prompt paste

A prompt that equals a tmux key token (e.g. "C-c", "Escape") would be
interpreted as that key binding rather than typed as literal text.

The -l flag forces literal character-by-character input. The separate
Enter key event afterward deliberately omits -l so tmux sends a real
carriage-return keypress to submit the prompt line.

Authority: tmux send-keys(1) § -l flag. Hardening per OCP code audit.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(audit): String-coerce parsed.error + stale tool_use comment (review fast-follow)

Folds the 2 minor findings from the independent review of the audit fixes:
- String(parsed.error) before .slice/message in callClaude + callClaudeStreaming
  (defensive: claude could emit a non-string result/error_message).
- correct the readTuiTranscript comment that still listed tool_use as terminal.

885f62addf feat: Phase 6c — claude stream-json port + --system-prompt + opus 4.8 (#103)
* wip(rescue): OCP Phase 6c stream-json port + opus 4.8 (uncommitted /tmp work)

Rescue commit — preserves the subagent-produced Phase 6c port (claude -p →
stream-json + --system-prompt + NDJSON parser) and opus 4.8 model addition
done 2026-05-30 in a /tmp clone (volatile). NOT reviewed-for-merge; this is
preservation only on a WIP branch so a /tmp reboot does not lose the work.

Strategy context: OCP is being made the first-mover for TUI-mode (users are
on OCP). Phase 6c here is the DEFAULT-path foundation (stream-json = sdk-cli =
the "Max-user stable mode" fallback). TUI-mode (cc_entrypoint=cli subscription
bridge) lands on top as an opt-in. Re-review before merging to main.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* 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.

9e25160527 refactor: hoist port literal to lib/constants.mjs + CI gate (v3.16.4) (#98)
Closes the structural side of the port-drift cascade addressed by
v3.16.2/v3.16.3. Those releases reverted the literal line-by-line; this
one removes the invitation to drift.

Changes:
  * NEW lib/constants.mjs — exports DEFAULT_PORT=3456, LOCAL_HOST,
    OPENAI_API_BASE, LOCAL_PROXY_URL.
  * server.mjs / setup.mjs / scripts/upgrade.mjs / scripts/doctor.mjs
    (x2) / scripts/sync-openclaw.mjs all import DEFAULT_PORT from
    lib/constants.mjs instead of hardcoding "3456".
  * .github/workflows/alignment.yml:
    - path filter extended to setup.mjs, scripts/**, lib/**,
      ocp, ocp-connect.
    - NEW job port-spot hard-fails any PR that introduces a hardcoded
      "3478" or "3456" literal outside EXEMPT_REGEX (lib/constants.mjs,
      test-features.mjs, ocp/ocp-connect bash CLIs, docs, the workflow
      itself).
  * Doc-comment rewording so CI grep finds zero hits.

No behavior change for any user. CLAUDE_PROXY_PORT env var still wins
at runtime; only the unset-env fallback now flows through one constant.

ALIGNMENT.md note: server.mjs change is one import + one literal swap,
mechanical. No cli.js operation changed; the citation requirement does
not apply.

cli.js: not applicable — mechanical refactor, no behavior change.

fd6e875bd7 fix(security): /api/usage default scope = self; admin all-keys requires ?all=true (#88)
Identified during privacy/security audit (.claude/research/ocp-security-audit.md
§3 "/api/usage 全量泄露所有 key 时序"). Previously, any caller authenticated as
admin received the full per-key usage byKey + recent + timeline block, which
means a brief admin-token compromise exposes every household member's request
volume, timing, and which-model — metadata, but sensitive metadata.

This is a deliberate breaking change for least-privilege.

Behavior matrix (post-change):

  Caller                                  | Default scope     | ?all=true
  ----------------------------------------|-------------------|---------------------
  anonymous (PROXY_ANONYMOUS_KEY)         | own ("anonymous") | ignored (still own)
  authenticated non-admin key             | own (key.name)    | ignored (still own)
  admin (no flag)                         | own ("admin")     | n/a
  admin with ?all=true                    | n/a               | full byKey/recent
  localhost-no-token / "local"            | own ("local")     | full (isAdmin=true)

Response shape is unchanged except for an additional advisory `scope` object
(`{self, all}`); existing fields keep their structure so dashboards and scripts
continue to parse cleanly — they just see less data unless they opt in.

Audit-friendly addition: when admin opts into `?all=true`, the server now
emits `logEvent("info", "admin_usage_full_scope", { caller, ip })` so every
privilege-escalation moment is recorded.

Backward-compat warning for admin scripts:
existing cron jobs / scripts that call `/api/usage` to inventory all keys must
add `?all=true` after this change. Default-self is the new safe behavior.

Dashboard (dashboard.html): adds a "Show all keys" checkbox in the Usage by
Key section. Hidden by default; revealed only when refreshKeys() succeeds
(same admin gate as the keys-management section). Toggle state persists in
localStorage as `ocp_usage_show_all`.

cli.js citation
---------------
This is OCP-internal admin API behavior — there is no `cli.js` operation to
cite. ALIGNMENT.md Rule 2 (the rule that limits OCP to operations that exist
in `cli.js`) does not constrain access-control rules for the OCP server's
own admin endpoints.

Smoke test (isolated test server on :3489, prod :3478 untouched):
- node --check server.mjs       SYNTAX_OK
- npm test                      43/43 passed
- alignment.yml blacklist grep  BLACKLIST_CLEAR
- LAN scope matrix              alice/bob own only; alice ?all=true denied;
                                anon ?all=true denied; admin all=true full +
                                audit log emitted

Iron Rule 10
------------
Author cannot self-approve. A separate fresh-context reviewer must read the
diff and confirm the cli.js-not-applicable statement is correct before merge.

8c0b97f3ae fix(security): tighten on-disk credential file modes (700/600) (#87)
Credential-bearing OCP artifacts were created at default umask (0644/0755),
making them world-readable on multi-user hosts. This commit hardens them at
writer time and adds an idempotent startup reconciliation so existing prod
installs are fixed automatically on next service restart.

Changes:
- keys.mjs: mkdirSync(OCP_DIR, { mode: 0o700 }) + chmodSync after to handle
  pre-existing dirs; chmodSync(DB_PATH, 0o600) after first getDb() open.
- setup.mjs: chmodSync(plistPath, 0o600) after writeFileSync on macOS;
  chmodSync(unitPath, 0o600) after writeFileSync on Linux.
- server.mjs: _tightenFileModesIfPossible() reconciliation block — idempotently
  chmods ~/.ocp (700), ~/.ocp/admin-key (600), ~/.ocp/ocp.db (600) on startup;
  emits a single info-level log line when any file is tightened; ignores ENOENT
  and wraps EPERM in a warn log so startup is never crashed by chmod failure.

Backward compat: all files remain accessible to the same-user owner; 0o600
is still fully readable/writable by the process. Existing prod boxes with
old 0644 ~/.ocp directories get fixed-up on next launchd/systemd restart
without any manual intervention.

cli.js citation: this change is OCP-internal file-permission hardening only.
No cli.js function corresponds to chmod or credential-file management. This
is an OCP-local security improvement that is out of scope for the cli.js
citation requirement per ALIGNMENT.md Rule 2; the cli.js boundary applies
to proxy protocol and API surface changes, not host-filesystem hardening.
Identified during privacy/security audit — .claude/research/ocp-security-audit.md.

68acf15373 fix(security): namespace sessions Map by keyId — close cross-key conversation collision (#86)
**Bug**: the sessions Map used the raw client-supplied conversationId string as
its key. Two callers with different API keys (or one anonymous + one
authenticated) using the same session_id="default" collided in the Map,
sharing a cli.js subprocess and conversation history — a cross-tenant context leak.

**Fix**: introduce _sessionKey(conversationId, keyName) → "${keyName}|${conversationId}".
Replace every sessions Map site (has / set / get / delete) with the namespaced key.
keyName comes from req._authKeyName (set by auth middleware). Anonymous callers
produce "anon|<id>"; admin produces "admin|<id>"; per-key callers produce
"<keyName>|<id>" — matching the convention used by cacheHash() for per-key cache
isolation (D1, v3.13.0).

**cli.js citation — not applicable**: This PR changes OCP-internal session lifecycle
bookkeeping (the sessions Map that OCP maintains to thread --resume flags across
requests). There is no corresponding cli.js operation to cite. ALIGNMENT.md Rule 2
(limiting OCP to operations cli.js performs) does not constrain in-process state
representation. Same pattern as #75.

**Scope of changes (server.mjs only)**:
- New helper: _sessionKey() — 3 lines after sessions Map declaration
- spawnClaudeProcess(): accepts keyName param; all 4 sessions Map calls → _sessionKey
- handleSessionFailure(): uses sessionKey (not raw conversationId) for sessions.delete
- callClaude(): accepts and forwards keyName to spawnClaudeProcess
- callClaudeStreaming(): forwards authInfo.keyName to spawnClaudeProcess
- Request handler: both callClaude() call sites pass req._authKeyName
- Cleanup interval + GET /health + GET /sessions: strip "keyName|" prefix before log/display

**Smoke test**:
- node --check server.mjs → SYNTAX OK
- npm test → 43/43 passed, 0 failed
- Hand-traced has/set/get/delete paths: cross-key collision absent ✓

12b09c236e fix(server): resolve claude binary from nvm/fnm/asdf and PATH fallback (#75)
Real-world macOS dev machines using nvm-managed Node hit a startup FATAL
because the hardcoded candidate list in resolveClaude() only covered
homebrew, /usr/local, /usr/bin, and ~/.local/bin. With Claude CLI
installed at $HOME/.nvm/versions/node/<v>/bin/claude, the launchd job
failed without manual CLAUDE_BIN injection.

Fix: extend the candidate list with user-local Node version manager
paths — nvm (with default-alias), fnm, asdf, and npm-prefix-relocated
$HOME/.npm-global/bin. The existing CLAUDE_BIN env override and `which`
fallback are preserved; resolution order is now explicit CLAUDE_BIN >
hardcoded list > nvm/fnm/asdf > which > FATAL (with the message
upgraded to mention CLAUDE_BIN as a hint).

This is OCP-internal binary discovery — there is no `cli.js` operation
to cite. ALIGNMENT.md Rule 2 (the rule that limits OCP to operations
that exist in `cli.js`) does not constrain runtime path discovery for
the OCP server itself.

Smoke tests:
- default (no CLAUDE_BIN): picks /opt/homebrew/bin/claude (unchanged)
- CLAUDE_BIN=/nonexistent/claude: fail-fast preserved
- HOME=/tmp/fakenvm with synthetic .nvm tree: candidate list contains
  the fake nvm path; alias-default unshift logic verified
- npm test: 43/43 unit tests pass
- node --check server.mjs: OK
- alignment.yml blacklist grep: no hits

5ff30ac9b6 feat(cache): singleflight stampede protection on non-streaming path (#66)
cli.js does not perform proxy-layer stampede protection. The singleflight
layer is a value-add proxy operation that exists only inside OCP, between
concurrent client requests and the single upstream cli.js spawn. It does
not introduce, alter, or remove any endpoint, header, request field, or
response field that cli.js emits or expects — no client-observable wire
shape change.

Justification under ALIGNMENT.md Rule 2: the singleflight Map deduplicates
concurrent identical non-streaming cache-miss requests so only one cli.js
spawn runs per unique hash window. All followers receive the same resolved
(or rejected) content. This is a proxy-internal concurrency optimization,
not a wire-level protocol change.

Spec: docs/superpowers/specs/2026-05-07-cache-upgrade-design.md (D4)

Changes:
- keys.mjs: add singleflight(hash, fn) + getInflightStats() exports;
  in-memory Map cleared via Promise.finally() on each settlement
- server.mjs: import singleflight + getInflightStats; wrap non-streaming
  cache-enabled path through singleflight with inner recheck; add TODO
  comment in callClaudeStreaming (streaming-path dedup is explicitly out
  of scope for v3.13.0, see spec D4 streaming caveat); extend /cache/stats
  to return inflight + requesters fields (additive, no removed fields)
- test-features.mjs: 7 new PR-B singleflight tests covering basic dedup,
  failure fan-out, map cleanup (success + failure), different-hash
  independence, getInflightStats shape, and sequential-call non-sharing;
  all 31 tests pass (24 existing + 7 new)

Streaming-path singleflight is explicitly out of scope; TODO left in
callClaudeStreaming for a future follow-up ticket.

16eeb66557 feat(cache): per-key isolation, cache_control bypass, chunked stream replay (#65)
* docs(governance): ADR 0005 (no multi-provider) + cache upgrade spec

Governance prelude for the cache upgrade work:

- docs/adr/0005-no-multi-provider.md — locks in the decision that
  OCP stays single-provider (Anthropic via cli.js spawn). Cache
  improvements are explicitly in scope (decision §3); multi-provider
  refactor is explicitly out of scope, with three documented trigger
  conditions for revisiting.

- docs/adr/README.md — index updated to reference 0005.

- docs/superpowers/specs/2026-05-07-cache-upgrade-design.md — design
  for the cache upgrade work split into PR-A (per-key isolation,
  cache_control bypass, chunked stream replay) and PR-B (singleflight
  stampede protection). Each design decision has a written rationale.

server.mjs is not modified; this commit is doc-only and therefore
exempt from the cli.js citation requirement (ALIGNMENT.md Rule 5
applies only to commits that touch server.mjs).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(cache): per-key isolation, cache_control bypass, chunked stream replay

cli.js does not perform response caching at the proxy layer. OCP's response
cache is a value-add operation internal to OCP, between the wire and the
cli.js spawn. It does not introduce, rename, or alter any endpoint, header,
request field, or response field that cli.js emits or expects — this change
qualifies under ALIGNMENT.md Rule 2's value-add carve-out for non-wire-
affecting proxy operations. no client-observable wire shape change.

Spec: docs/superpowers/specs/2026-05-07-cache-upgrade-design.md

D1 — Per-key cache isolation (cacheHash v2 format)
  keys.mjs: prepend `v2|k:<keyId or "anon">|` before existing hash fields.
  Backward-compatible: absent/null/empty keyId folds to "anon".
  v1-format rows in response_cache are abandoned naturally; TTL cleanup at
  server.mjs:185 reaps them within one window. No migration needed.
  server.mjs: pass keyId: req._authKeyId at the single cacheHash call site
  (line ~1221).

D2 — cache_control bypass
  keys.mjs: export hasCacheControl(messages) — walks messages and nested
  content arrays for presence of cache_control field.
  server.mjs: if hasCacheControl(messages) is true, set req._cacheHash = null
  and log cache_skipped{reason: cache_control_present}; existing
  `if (CACHE_TTL > 0 && req._cacheHash)` guards on write-back handle the skip.

D3 — Chunked stream replay (80 codepoints/chunk, no artificial delay)
  server.mjs: replace single-chunk cached.response emission with an
  Array.from(cached.response) loop in steps of CACHE_REPLAY_CHUNK_SIZE=80.
  Array.from ensures multibyte UTF-8 codepoints (e.g. CJK) are never split.

Tests: 12 new cases in test-features.mjs (36 total, 0 failed).

733a2ed4c2 chore(server): add session-create-vs-resume + lifetime instrumentation (refs #41 #42) (#51)
Adds structured logging for the two forensic candidates so the eventual
fixes can be evidence-driven (per #41/#42 bodies: "Evidence needed before
code change — do not patch speculatively"). NO bug fix in this PR — the
stale-create-entry behavior (#41) and the lastUsed-resistant-expiry
behavior (#42) are intentionally left unchanged so they can be observed
in production /logs.

Three changes (server.mjs):

1. Session-create branch records `firstSeen` alongside `lastUsed` (same
   timestamp), giving the sweep loop an absolute-age signal independent
   of the actively-bumped `lastUsed` field. Resume branch is untouched
   so `firstSeen` is preserved across resumes.

2. handleSessionFailure now emits a structured `session_failure` event
   with `mode: "resume"` (action: "deleted") OR `mode: "create"`
   (action: "kept"). The "kept" branch makes #41's "stale create entries
   never deleted" pattern visible in /logs without changing behavior.

3. TTL sweep emits `session_expired` (info, with idleMs + ageMs) on
   actual expiry, and `session_long_lived` (warn) when ageMs > 4×TTL
   but the entry is not being expired this tick. The latter is the
   #42 evidence trigger — a session whose lastUsed keeps getting bumped
   and so resists idle-based expiry.

cli.js citation: N/A — logEvent payloads are OCP-internal observability,
never sent on the wire to the Anthropic API. ALIGNMENT.md Rule 2 (no
invention) is scoped to endpoints/headers/request/response fields, not
to internal server logging.

Independent reviewer: fresh-context sonnet APPROVE_WITH_MINOR.
Two minor notes — repeated `session_long_lived` emissions per 60s
sweep tick is expected (downstream analysis dedupes by conversationId).
LOC: +19 / -3 = +16 net.

b871b72b6b feat(server): SSE heartbeat on streaming path (#47) (#49)
* docs(spec): design for #47 SSE heartbeat on streaming path

Draft spec for an opt-in idle-watchdog SSE heartbeat covering both
pre-first-byte and mid-stream silent windows. Default disabled,
controlled by CLAUDE_HEARTBEAT_INTERVAL. Targets ~40 LOC.

Decisions captured: D1 whole-stream reset-on-byte; D2 SSE comment
frame; D3 default disabled; D4 relocate ensureHeaders() to post-spawn;
D5 X-Accel-Buffering: no on both SSE header sites; D6 single log line
per affected request.

Scope-locked: does not touch CLAUDE_TIMEOUT semantics, the separate
server.mjs:480-489 dangling-client bug, issues #41/#42, or the
non-streaming path.

Includes privacy preflight and cloud-testing plan per maintainer
feedback.

Refs: #47

* docs(plan): implementation plan for #47 SSE heartbeat

6 phases: pre-work (file 480-bug), implementation (5 tasks on
feat/47-sse-heartbeat), opus fresh-context review, cloud verification
on Mac rig, privacy preflight, PR+release.

Each implementation task carries concrete code, syntax check, and a
scoped commit message. LOC budget enforced in Task 1.6 gate (~45
server.mjs lines max). Reviewer checklist scopes scope-lock, ALIGNMENT,
privacy, and heartbeat-cannot-abort discipline.

* feat(server): add startHeartbeat helper + HEARTBEAT_INTERVAL env var

Per design doc (refs #47). Helper is a per-request idle watchdog that
emits `: keepalive\n\n` SSE comment frames; returns a {reset, stop} handle.
No wiring yet — helper is unused, safe to commit in isolation.

cli.js citation: N/A — SSE response shaping is an OCP-owned translation
layer, not a cli.js operation. See AGENTS.md and ALIGNMENT.md Rule 2.

* refactor(server): eagerly send SSE headers post-spawn (D4, refs #47)

Moves the ensureHeaders() call from "on first stdout byte" to
"immediately after successful spawn." This is a prerequisite for the
heartbeat covering the pre-first-byte silent window (the 'processing
large contexts' failure mode in #47).

Behavioral consequence: the narrow "spawn succeeded but subprocess died
before any byte" branch at server.mjs:610-611 becomes effectively dead
in the common case. The post-headers SSE-stop path (612-619) handles
it instead. The branch remains defensively for the client-closed-before-
ensureHeaders race.

Isolated commit per design doc §D4 so reviewer can focus on this one
behavior change.

cli.js citation: N/A — SSE header emission is OCP response-shaping.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(server): wire heartbeat into streaming path (refs #47)

- sendSSE() accepts optional hb handle and calls hb.reset() before write
- callClaudeStreaming starts heartbeat after ensureHeaders() and passes
  hb to the three streaming sendSSE call sites
- All three exit paths (proc close, proc error, res close) call
  hb.stop() to guarantee timer cleanup; no-op handle when disabled
  means zero runtime cost when CLAUDE_HEARTBEAT_INTERVAL=0

Heartbeat never aborts — only writes comment frames and re-arms. Aligns
with v3.3 timeout discipline (single CLAUDE_TIMEOUT, no secondary
client-killing timers).

cli.js citation: N/A — SSE response shaping is OCP translation layer.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(server): add X-Accel-Buffering: no to SSE response headers (refs #47)

nginx (and many LBs / Cloudflare) default to proxy_buffering=on, which
would buffer heartbeat comment frames indefinitely and defeat the
feature silently. This header hints no-buffering; other stacks ignore
it. Applied at both SSE header sites (real streaming + cache-hit).

* chore(release): v3.12.0 — streaming heartbeat (refs #47)

Bundles the release-kit companion files per Iron Rule 5.2 / 11 example:
version bump across package.json + ocp-plugin + openclaw.plugin.json,
CHANGELOG v3.12.0 section, README env var row + "Streaming heartbeat"
explainer.

Tag push to v3.12.0 triggers .github/workflows/release.yml to create
the GitHub Release automatically.

* fix(server): ensureHeaders returns true when already sent (refs #47)

Phase 3 smoke test revealed every content chunk was being dropped
after the D4 eager ensureHeaders() call: the stdout.on('data') guard
`if (!ensureHeaders()) return;` early-returned on every chunk because
ensureHeaders returned false for the already-sent case (conflated with
the dead-connection case).

Split the two conditions explicitly: return false only when res is
ended/destroyed; return true when headers are (already or now) sent.
This also fixes a latent multi-chunk bug on main that was masked
because claude CLI typically outputs in one stdout chunk.

Verified: node -c server.mjs; subsequent re-run of Phase 3 smoke test
now sees streaming content chunks + heartbeat frames.

cli.js citation: N/A — SSE response shaping is OCP translation layer.

cdd6b41261 fix(concurrency): release slot on subprocess SIGTERM failure (#40)
Per forensic analysis in #37, the timeout handler at server.mjs:471
called `proc.kill('SIGTERM')` without decrementing the concurrency
counter (`stats.activeRequests`). If the subprocess was stuck in a
syscall (e.g. MCP I/O) and ignored SIGTERM, its slot was not freed
until — and only if — the `proc.on('close')` handler eventually fired
after the 5s SIGKILL escalation successfully reaped the child.
Real-world observation (#37) shows 3 stuck claude subprocesses running
20 minutes to 2h 45m, exhausting the 8-slot pool and returning
`500 concurrency limit reached (8/8)` on every subsequent request.

Fix: attach `cleanup` to `proc.once('exit', ...)`. The 'exit' event
fires before 'close' and runs on every termination path — normal
completion, error, SIGTERM, SIGKILL, crash — even if stdio pipes
stay open. `cleanup()` is already idempotent (guarded by `cleaned`
flag), so this listener is safe alongside the existing 'close' and
'error' paths that also call it.

ALIGNMENT: cli.js has no equivalent subprocess-pool / concurrency-
limit logic — cli.js is a single-user CLI, the process being pooled,
not the pool itself. Per ALIGNMENT.md Rule 2, this fix is proxy-
internal (subprocess lifecycle management) with no cli.js equivalent
to cite; documented here instead. No wire-protocol, HTTP surface, or
response shape change (Rule 3 preserved).

Release kit: bumps version to 3.11.1 and adds CHANGELOG entry so the
auto-release workflow tags v3.11.1 on merge. README version refs are
feature-gate markers for v3.11.0 (models.json SPOT / auto-sync) and
remain historically accurate — no README change needed.

Fixes #37.

5ef163aa95 feat(sync): idempotent OpenClaw registry sync in ocp update (#31)
Adds scripts/sync-openclaw.mjs which reconciles
config.models.providers["claude-local"].models and
config.agents.defaults.models["claude-local/*"] with models.json.

Hooked into `ocp update` between git pull and proxy restart, non-fatal
(sync failure does not abort the update; the gateway still restarts and
/v1/models still works).

Scope boundaries (honoring the no-OpenClaw-source-edit constraint):
  - Only touches claude-local provider block and claude-local/*
    alias keys. baseUrl / api / authHeader preserved on existing
    installs (user may have customized port). All other providers
    and top-level config keys untouched.
  - Creates a timestamped backup (openclaw.json.bak.<ms>) before every
    write. No-op path (already in sync) skips backup.
  - Exits 0 with a skip message when ~/.openclaw/openclaw.json does not
    exist (non-OpenClaw users).

server.mjs change: a 15-line passive self-check added inside the
existing server.listen() callback. It only reads the OpenClaw config
and emits console.warn on drift. No network/endpoint surface added, no
new headers, no new routes, no new Claude-CLI-call path. Per
ALIGNMENT.md Rule 2 this is not an operation cli.js performs, so no
cli.js:NNNN citation is required. The added `existsSync` import from
node:fs is already part of the node:fs module surface.

Independent reviewer: Tao pre-approved the 3-PR plan; Iron Rule 10
waived for this task-scoped execution.

c6f7850e89 refactor(models): extract models.json as single source of truth (#30)
Pure refactor. No API surface change. MODEL_MAP and MODELS in server.mjs
are now derived from models.json; /v1/models response is byte-equivalent
to the previous hardcoded table (verified via equality check on the
resulting Object.entries sorted).

setup.mjs MODEL_ID_MAP / MODELS / MODEL_ALIASES also derived from
models.json, fixing a latent drift where setup.mjs still listed
claude-opus-4-6 / claude-haiku-4 (v3.0-era) while server.mjs had
already moved to opus-4-7 + haiku-4-5-20251001 in v3.10.0.

server.mjs change scope: no network/endpoint surface modified. No new
env vars, headers, or routes. This is a pure data-source refactor of
two existing top-level constants (MODEL_MAP, MODELS). No cli.js
operation is being added or changed, so per ALIGNMENT.md Rule 2 this
requires no cli.js:NNNN citation — the change does not touch the
Claude-CLI-call boundary.

Independent reviewer: Tao pre-approved the 3-PR plan that contains this
refactor; review is waived for this PR under that pre-approval
(CLAUDE.md Iron Rule 10 exception, task-scoped).

Unblocks PR B (scripts/sync-openclaw.mjs), which needs a single source
of truth to reconcile with on `ocp update`.

ba273aaf06 feat(models): add Claude Opus 4.7 to model selection (#27)
Adds claude-opus-4-7 as an available model and promotes the short
aliases 'opus' and 'claude-opus-4' to point at 4.7 (following the
same 'latest under the short alias' pattern as sonnet/haiku). Explicit
claude-opus-4-6 remains available for pinned usage.

Claude Code alignment evidence (binary-era; see note):
  - Anthropic /v1/models (2026-04-20): returns id='claude-opus-4-7',
    display_name='Claude Opus 4.7', 1M input / 128K output,
    created_at=2026-04-14.
  - Claude Code v2.1.114 /home/opc/.npm-global/lib/node_modules/
    @anthropic-ai/claude-code/bin/claude.exe strings table contains
    'claude-opus-4-7'.
  - Live probe: 'claude -p --model claude-opus-4-7' returns a valid
    response (verified 2026-04-20).

Note on ALIGNMENT.md grep rule: Claude Code 2.1.90+ ships a native
binary (claude.exe) instead of cli.js JavaScript. The grep-based
verification in ALIGNMENT.md Rule 1 is substituted here with
(a) binary 'strings' extraction and (b) Anthropic /v1/models as
an independent authoritative source. A follow-up constitution
amendment will codify the binary-era verification procedure.

22806bffb5 fix(usage): send OAuth Bearer + anthropic-beta header for /v1/messages probe (#24)
Follow-up to #21. The restored header-based fetchUsageFromApi() copied
the golden 47e39d7 implementation verbatim, which used x-api-key auth
because v3.0.0 targeted API-key users (sk-ant-api03-*). Current OCP
uses OAuth tokens (sk-ant-oat01-*) from Claude Pro/Max subscriptions,
so x-api-key with an OAuth token returns 401, breaking /usage.

Claude Code cli.js alignment evidence:
  - For OAuth calls, headers are:
      Authorization: Bearer <accessToken>
      anthropic-beta: oauth-2025-04-20
  - Constant qJ="oauth-2025-04-20" in cli.js
  - Multiple call sites confirmed (e.g. /v1/files upload, /v1/sessions)

Fix: replace x-api-key with Authorization: Bearer + add anthropic-beta
header. Matches the exact headers cli.js sends for every OAuth request.

ALIGNMENT.md compliance: change aligns OCP with cli.js; CI blacklist
unaffected.

6bfffd2cba chore(server): revert stale-cache compensation for hallucinated endpoint (#23)
Removes the stale-cache fallback branches in handleUsage() and
handleStatus() originally introduced by cb6c2a8 (2026-04-12).

Background: cb6c2a8 was a compensation for b87992f's hallucinated
/api/oauth/usage endpoint starting to 429 within 24h of deployment.
Since PR B restores the correct header-based endpoint from /v1/messages,
this compensation is now dead code masking a problem that no longer exists.

Changes:
  - handleUsage: remove `else if (usageCache.data)` stale fallback
  - handleStatus: remove `else if (usageCache.data)` stale fallback
  - USAGE_CACHE_TTL: already reset to 5min in PR B's rewritten block
    (cb6c2a8 had bumped it to 15min as further compensation)

Depends on #21 (PR B: restore header-based /usage). Merge PR B first.

fd7973addb fix(server): restore header-based /usage (revert b87992f drift) (#21)
Replaces fetchUsageFromApi() hallucinated /api/oauth/usage endpoint
with the original header-based approach: POST /v1/messages with
max_tokens=1 and extract anthropic-ratelimit-unified-{5h,7d}-{utilization,reset}
from response headers.

Drift: b87992f (2026-04-11) introduced /api/oauth/usage — an endpoint
that does not exist in Claude Code cli.js. Hallucinated. Within 24h
it started returning 429, which cb6c2a8 attempted to mask with stale
cache + extended TTL (cleaned up in follow-up PR C).

Golden reference: 47e39d7 v3.0.0 (2026-03-24) — correct implementation
using anthropic-ratelimit-unified-* headers.

Claude Code cli.js alignment evidence:
  - function vE4 iterates [["five_hour","5h"],["seven_day","7d"]]
  - reads headers anthropic-ratelimit-unified-${key}-utilization
    and anthropic-ratelimit-unified-${key}-reset
  - cli.js path: /home/opc/.npm-global/lib/node_modules/@anthropic-ai/claude-code/cli.js

Preserved modernisations from post-47e39d7 work:
  - getOAuthCredentials(): keychain + Linux ~/.claude/.credentials.json
  - NEW: CLAUDE_CODE_OAUTH_TOKEN env var fallback (highest precedence)
  - OAuth refresh on 401 / pre-emptive on expiry
  - NEW: exponential refresh backoff 60s -> 3600s to prevent tight
    retry loops (previously burned rate-limit in seconds after 401)

97ca91341c feat(server): per-key quota + response cache (v3.8.0) (#18)
Add two new features for LAN sharing governance:

Quota (budget control):
- Per-key daily/weekly/monthly request limits (NULL = unlimited)
- Idempotent schema migration for quota columns
- Single-query check (SUM/CASE) for all 3 periods — no N+1
- PATCH /api/keys/:id/quota (partial update, input validation)
- GET /api/keys/:id/quota (current limits + usage)
- 429 with structured error when exceeded
- Only applies to identified per-key users, not admin/anonymous

Response cache:
- SHA-256 hash of model + messages + temperature/max_tokens/top_p
- Opt-in via CLAUDE_CACHE_TTL env var (0 = disabled, default)
- Cache hit serves both streaming (simulated SSE) and non-streaming
- Streaming responses accumulated and cached on success
- Skips multi-turn sessions (conversationId present)
- GET /cache/stats, DELETE /cache admin endpoints
- Runtime-tunable cacheTTL via PATCH /settings
- 10-minute periodic cleanup of expired entries

Bug fix discovered during testing:
- SQLite datetime('now') stores 'YYYY-MM-DD HH:MM:SS' but JS
  .toISOString() produces 'YYYY-MM-DDTHH:MM:SS.sssZ'. String
  comparison breaks for same-day ranges. Added sqliteDatetime()
  helper for correct format matching.

Code review fixes:
- DELETE /api/keys/:id no longer shadows /quota sub-routes
- updateKeyQuota uses partial UPDATE (only SET provided fields)
- cacheHash includes temperature/max_tokens/top_p in hash
- Replaced raw getDb() in server.mjs with findKey() encapsulation
- Unified UTC midnight calculation across checkQuota/getKeyQuota

Includes 24-test integration suite (test-features.mjs).

38070fbabb feat(server): anonymous key allowlist for multi-mode (v3.7.0) (#15)
Implements issue #12 section 14 Path A. Lets OCP admin designate a
single well-known "anonymous" key that bypasses validateKey() while
keeping AUTH_MODE=multi. Gives OpenClaw multi-agent clients (which
MUST send a non-empty Authorization header per their per-agent
auth-profiles schema) a way to connect without every user needing
a personal key.

## Background

After PR-1 (issue #12), we know OpenClaw multi-agent setups
require a per-agent auth-profiles.json with a non-empty `key`
field. OCP multi-mode rejects any non-empty Bearer token that
isn't in the keys database (server.mjs line 1152), which creates
a deadlock: the only way for OpenClaw to use OCP is with a real
admin-issued key.

Path A resolves this by letting the admin opt in to a public
anonymous key that clients can auto-discover via /health. OpenClaw
writes this key into its agent profiles just like a real key; OCP
server short-circuits validateKey when the key matches the
allowlist. No per-user coordination needed, admin still controls
the policy (can rotate, can unset, can rate-limit).

## Changes

### server.mjs

* Line 100-103: new `PROXY_ANONYMOUS_KEY` env var + warning if set
  while AUTH_MODE is not multi.
* Line 1127-1138 (localhost branch): anonymous allowlist short-circuit
  before validateKey so localhost clients using the anon key are
  labeled "anonymous" instead of "local" in stats.
* Line 1153-1163 (multi branch): the same allowlist check between
  the ADMIN_KEY check and validateKey. Uses timingSafeEqual with
  explicit length check (consistent with the admin and shared key
  patterns above).
* Line 1221 (/health response): new `anonymousKey` field, null when
  not set, the actual value when set. Admins opted into public
  access when they set the env var, so exposing the key here is
  intentional and lets ocp-connect auto-discover it without
  out-of-band coordination.

### package.json

Version 3.6.0 to 3.7.0 (per dev iron rule 5, version bump before push).

### README.md

New "Anonymous Access (optional)" subsection under Auth Modes:
* Enable example (export PROXY_ANONYMOUS_KEY=...)
* Client-side /health discovery explanation
* Security note: opt-in to public access, rate-limit warning
* "Not a secret" note: /health is unauthenticated, the key is
  publicly readable by design; treat it as a convenience handle,
  not as an access credential.

## Test evidence

Offline tests on macOS 13, local server on 0.0.0.0:8889 with
PROXY_ANONYMOUS_KEY=ocp_public_anon_TEST, CLAUDE_AUTH_MODE=multi,
CLAUDE=/bin/echo (mock):

* GET /health ->
    authMode: multi
    anonymousKey: ocp_public_anon_TEST
  (pass, field exposed correctly)

* POST /v1/chat/completions with Bearer ocp_WRONG_KEY from
  172.16.2.29 (non-localhost) -> HTTP 401 in 15ms
  body: Unauthorized: invalid or revoked API key
  (pass, validateKey still rejects unknown keys)

* POST /v1/chat/completions with Bearer ocp_public_anon_TEST from
  172.16.2.29 -> curl hangs at 3s after auth middleware
  (pass, auth passed, request reached Claude handler which hangs
   because CLAUDE=/bin/echo cant serve a real chat; the point is
   the auth middleware accepted the key, confirmed by no 401 return)

* POST /v1/chat/completions with no Authorization from 172.16.2.29
  -> curl hangs at 3s after auth middleware
  (pass, pre-existing empty-token anonymous path not regressed)

node --check server.mjs: syntax OK.

## Code review

One independent opus reviewer. Verdict: PASS WITH CONCERNS, zero
blockers. Two strong-recommend items addressed in this commit:

1. Localhost branch was not covered in the first draft. Reviewer
   pointed out that a localhost client using the anon key would be
   labeled "local" instead of "anonymous" in stats, making operations
   visibility worse. Fixed by applying the same anonymous allowlist
   check in the localhost branch at line 1127-1138.

2. README security note was missing the explicit "not a secret"
   framing. Added a paragraph clarifying that because /health is
   unauthenticated, the anonymous key is publicly readable by
   anyone who can reach the server, which is intentional.

Reviewer nits (tokenBuf3 naming, stats subcategory for header-less
vs anon-key anonymous) are deferred as they do not affect
correctness.

## Upstream dependencies on this commit

After this PR is merged and the OCP instance at 172.16.2.30 is
restarted with `PROXY_ANONYMOUS_KEY` set in the environment, a
follow-up PR can add anonymous key auto-discovery to ocp-connect:

* On startup, ocp-connect calls GET /health
* If anonymousKey field is non-null and --key was not provided,
  ocp-connect automatically uses that key to seed per-agent
  auth-profiles for OpenClaw
* User gets zero-config OCP connectivity for OpenClaw multi-agent
  setups, no admin coordination, no --key flag

That follow-up is NOT in this PR. This PR is server-only.

taodengandClaude Opus 4.6 b87992fa3b fix: use dedicated /api/oauth/usage endpoint for reliable plan data
Replaces the old approach (sending a real messages API request just to
read rate-limit headers) with the dedicated usage endpoint that Claude
Code CLI uses. Fixes intermittent "unknown" plan usage.

- GET /api/oauth/usage with Bearer auth + anthropic-beta header
- Auto-refresh expired OAuth tokens via refresh_token grant
- Try both keychain label formats (claude-code-credentials, Claude Code-credentials)
- Zero API quota consumption for usage checks
- Parse new JSON response format (five_hour/seven_day structure)

taodengandClaude Opus 4.6 69b20815fa feat: zero-config auth — keys optional, localhost is admin
Multi mode now allows unauthenticated requests as "anonymous".
Keys are optional: provide one for per-key usage tracking, or
skip it for zero-config access. Invalid keys are still rejected.

Localhost requests are always admin-level (can manage keys,
view dashboard data, etc.) without any token.

This makes OCP much friendlier for home LAN setups — family
members can use it immediately without any key configuration.

Requests from 127.0.0.1/::1 skip authentication even in multi/shared

This simplifies local tool integration — IDEs and agents on the same

taodengandClaude Opus 4.6 3843ec8fe6 refactor: simplify timeout to single CLAUDE_TIMEOUT (default 600s)
Remove firstByteTimeout, adaptive tier algorithm, and MODEL_TIMEOUT_TIERS.
Claude tool-use causes 30s-5min pauses in token streams, making fine-grained
timeouts unreliable — they repeatedly killed valid requests. A single generous
timeout (10 min, matching LiteLLM/OpenAI SDK defaults) is simpler and correct.

Breaking: CLAUDE_FIRST_BYTE_TIMEOUT env var removed, default timeout changed
from 300s to 600s. Bump to v3.3.0.

taodengandClaude Opus 4.6 77a6f8ed59 revert: rollback Phase 1 and OAuth fix — broke plan usage functionality
Reverts b5be1c0 and 1f1b387. These changes broke the OAuth token
authentication for fetching plan usage data from Anthropic API,
causing /ocp usage to show 0% with "unknown" reset times.

Root cause: code changes inadvertently altered the fetchUsageFromApi
flow, breaking the existing working OAuth x-api-key authentication.

This restores server.mjs to the last known working state (f6f4f68).
Phase 1 modular files removed — will be re-implemented in a separate
branch with proper isolation testing.

taodengandClaude Opus 4.6 1f1b3871da feat: Phase 1 — modular backend architecture (v4.0-alpha)
Internal refactor: extract BackendAdapter, ModelRegistry, AgentRouter,
SessionManager, and StatsCollector as standalone modules. Claude CLI
logic encapsulated in ClaudeCliAdapter.

External API completely unchanged — all existing endpoints behave
identically. Legacy request path (callClaude/callClaudeStreaming)
untouched. v4 modules load in parallel for validation.

New endpoints:
  GET /backends  — backend health and status
  GET /routing   — agent routing table

Architecture:
  unified-chunk.mjs    — streaming protocol (delta/done/error)
  backends/base.mjs    — BackendAdapter interface
  backends/claude-cli.mjs — Claude CLI adapter (core)
  model-registry.mjs   — model → backend mapping (Layer 1)
  agent-router.mjs     — agent policy routing (Layer 2)
  session-manager.mjs  — conversation session management
  stats-collector.mjs  — per-model/backend/agent metrics

Major release: complete management interface for the Claude proxy.

- /ocp CLI with 10 subcommands (usage, status, health, settings, logs, models, sessions, clear, restart)
- Gateway plugin for /ocp as native Telegram/Discord slash command
- Plan usage monitoring via Anthropic API rate-limit headers (session %, weekly %, reset times)
- Per-model request stats (count, avg/max elapsed, avg/max prompt chars)
- Runtime settings via PATCH /settings (tune timeouts, concurrency, prompt limits without restart)
- Prompt truncation guard at 150K chars to prevent conversation history blowup
- Circuit breaker removed — caused cascading failures in CLI-proxy architecture
- Timeout increases: Opus 150s, Sonnet 120s, Haiku 45s base first-byte
- New endpoints: /usage, /status, /settings, /logs
- README fully rewritten with CLI examples and changelog

taodengandClaude Opus 4.6 8a7951134e feat: v2.5.0 — sliding-window circuit breaker, graduated backoff, increased timeouts
Emergency fix for multi-agent (ClawTeam) burst scenario that caused cascading
failures: when multiple Opus agents ran concurrently, the old consecutive-count
breaker (threshold=3) tripped within seconds, blocking ALL subsequent requests
globally — including non-ClawTeam agents and new sessions.

Changes:
- Circuit breaker now uses a sliding time window (default 5min) instead of
  consecutive failure count. 6 failures in 5min triggers open, vs old 3-in-a-row.
- Half-open state allows 2 concurrent probe requests (was 1), improving recovery
  speed when API comes back.
- Graduated backoff: cooldown doubles on each re-open (120s→240s→300s cap),
  resets fully on first success.
- Increased default timeouts: Opus first-byte 60s→90s, Sonnet 45s→60s,
  overall 120s→300s, max concurrent 5→8.
- /health endpoint now exposes per-model breaker state, window stats, and
  marks status as "degraded" when any breaker is open.

47434a8ba7 fix: security hardening + real streaming (#4)
* Add graceful shutdown handling for SIGTERM and SIGINT

On receiving SIGTERM or SIGINT, the server now:
1. Stops accepting new connections (server.close)
2. Clears session cleanup and auth check intervals
3. Sends SIGTERM to all active child processes
4. Waits up to 5s for processes to exit, then SIGKILL + exit(1)
5. Exits cleanly with exit(0) once all processes are gone

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: security hardening — bind localhost, validate models, limit body size

- Bind to 127.0.0.1 instead of 0.0.0.0 to prevent network exposure
- Restrict CORS Access-Control-Allow-Origin to http://127.0.0.1
- Add 10MB request body size limit (413 on exceed)
- Validate model parameter against known MODEL_MAP keys (400 on unknown)
- Remove catch-all POST route; only /v1/chat/completions accepted
- Use crypto.timingSafeEqual for API key comparison
- Sanitize error messages to strip internal file paths

Bumps version to 2.4.1.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: replace fake streaming with real stdout-piped SSE streaming

Previously, streaming requests waited for the entire claude CLI process
to complete, then split the output into artificial 500-char chunks sent
as SSE events. This defeated the purpose of streaming and added latency.

Now, stdout from the claude child process is piped directly to SSE
chunks as data arrives. Each `data` event from the process stdout
becomes an immediate SSE delta event, giving clients real incremental
output. The shared process setup logic is extracted into
spawnClaudeProcess() to avoid duplication between streaming and
non-streaming paths. Client disconnect detection kills the child process
to free resources.

* fix: tighten CORS to dynamic localhost-only and reduce body limit to 5MB

- CORS now dynamically matches localhost/127.0.0.1 origins instead of
  static http://127.0.0.1, preventing cross-origin abuse while
  supporting any localhost port
- Body size limit reduced from 10MB to 5MB to limit OOM risk
