Summary

Adds GET /api/quota-pool, the producer side of GOAT's ocx.quota-pool/1 contract (goat-si/goat packages/contracts/src/quotaPool.ts on feat/quota-pool-contract, #690; design in #684 §3.3, consumer refinement in #695). GOAT can now read every account quota this Home already tracks in one provider-neutral shape, either on the Home or from a Child at GET /api/machine/hub-relay/api/quota-pool.

The read is passive for every caller. The whole assembly runs inside runPassiveRead and reads only existing caches:

• Codex pool StoredAccountQuota and the main-account reading, from the passive account list.
• Held provider reports, reported as pooled; for the Codex pool this is OpenCodex's own aggregate.
• The per-account OAuth quota cache: Anthropic instances, Kiro, Antigravity groups, xAI, Cursor, Kimi, Command Code, Devin, DSH and Meta.
• The Claude CLI usage-admission snapshot, including a parsed CLI limit refusal.

No probe, token refresh, upstream call or cache write happens on this path. A refresh query is ignored.

Contract rules:

• An unknown window is omitted, never reported as 0%. A window whose reset has already passed is omitted too. Optional fields are left out instead of set to null.
• Window kinds come from what the existing parsers stored. A short Codex primary maps to burst_5h, with windowSeconds only when upstream stated it; 7-day maps to weekly; Kiro and USD credits map to credits with a unit.
• Proven model scope becomes scopeModel. Such a window never makes the whole account exhausted. Unscoped exact-model rows are dropped.
• Refusal evidence becomes exhausted: true.

Identity:

• accountRef is acct_ + base64url(HMAC-SHA256(per-install secret, provider ‖ accountId)), truncated to 128 bits. It is stable across restarts, distinct per provider, and never an email, raw id or token.
• homeId (home_<32 hex>) and the secret live in <OPENCODEX_HOME>/quota-pool-identity.json (owner-only). The server mints the file at startup, so the read path only reads it, or returns 503 quota_pool_identity_unavailable.
• Creation is exclusive and never follows a link (private temp file hard-linked into place). Concurrent first starts adopt one identity, and a symlink or malformed file at the path is refused, never overwritten.
• Account labels reuse the existing log labels (main, p<hex6>, o<hex6>).
• producer.role follows runtimeRole; producer.version is the package version.

Surfaces:

• Home: authorized like the neighbouring management reads.
• Remote Link Child: the path is added to LINK_MANAGEMENT_READ_PATHS. The shared refresh-key rule still refuses a link read that carries refresh, reload, force or quota. GOAT never sends these.
• Hub client: the existing hub relay already forwards /api/* with the caller's management credential, so no relay change was needed.

Not produced yet: driver (no confirmed GOAT ProviderDriverKind mapping) and pooled.headroom.

Docs: new structure/quota-pool.md, plus updates to gui-and-management-api.md, remote-link.md and the docs-site management API reference.

Management/relay read surface: needs maintainer security review. This exposes account quota over the link relay and the hub relay. The response carries only opaque references, log labels and quota numbers.

Verification

• bun run typecheck: pass.
• tests/usage/quota-pool.test.ts: contract shape snapshot against a strict local zod mirror (tests/helpers/quota-pool-schema.ts), no null anywhere, absent-not-zero and elapsed-reset cases, kind mapping through parseUpstreamQuotaHeaders, preserved scope and refusal verdicts, accountRef stability across a restart, rotation, and no email, raw id or token in the body. It also covers symlink and malformed-file refusal, and four processes racing on a fresh home agreeing on one identity.
• tests/server/quota-pool-relay.test.ts: a real Home with an expired-token Codex pool account. It exercises the authenticated Home read (including ?refresh=1), the Remote Link relay (link key only; writes refused) and the Hub-client relay. Any fetch, spawn or file write inside the read fails the test, and so does any change to the Home's files. I drove it red by injecting a WHAM fetch into the assembler: all three paths failed.
• tests/server/link-management-relay.test.ts now covers /api/quota-pool through its allowlist loop and stays green.
• Route registry, core Lab boundary, quota boundary, test-layout, structure-ssot and repo-hygiene tests: pass.
• bun run test:changed: 34498 pass / 42 skip / 0 fail.
• bun run privacy:scan, bun run structure:check and bun run skill:surface:check: pass.
• bun run test (full, under the shared lock): one failure, claude-desktop-remote-hub.test.ts > connected Desktop uses hub IDs across a cold restart (stored profile=false), a model-list ordering mismatch. It fails identically on the untouched base 845ac6b87 on this machine and passes in CI test shards 1–4, so it is a pre-existing local environment failure, unrelated to this change. Everything else passed.
• Review fixes (exclusive identity creation, passive reauth state, CORS headers) re-verified: focused files, the link relay test run in-process together with the new files, route registry, boundary guards, typecheck, structure and privacy. The full suite above ran on e1ab5d090; CI covers head 3a7db3ee9.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

📝 Walkthrough

Adds the ocx.quota-pool/1 contract and a passive producer that assembles cached quota observations. The management API serves the response through Home and relay routes. Identity handling, authorization, validation, tests, and documentation are also added.

Changes: Quota Pool API

Layer / File(s)	Summary
Contract and install identity src/quota-pool/contract.ts, src/quota-pool/identity.ts, src/server/background-lifecycle.ts	Defines the response types and persisted install identity. Account references use HMAC-derived opaque values. Server lifecycle acquisition attempts identity creation and continues if it fails.
Passive quota assembly src/adapters/claude-cli/usage-admission.ts, src/codex/quota-history.ts, src/codex/quota.ts, src/quota-pool/assemble.ts	Adds read-only access to cached observations and assembles provider and account quota windows, account states, sources, and producer metadata. Unknown or expired windows are omitted.
Management and relay access src/server/management-api.ts, src/server/management/quota-pool-routes.ts, src/server/management/route-registry.ts, src/link/management-routes.ts	Registers GET /api/quota-pool. The route returns JSON with no-store; the Remote Link read allowlist includes the endpoint.
Validation and documentation tests/helpers/quota-pool-schema.ts, tests/usage/quota-pool.test.ts, tests/server/quota-pool-relay.test.ts, structure/quota-pool.md, docs-site/src/content/docs/reference/management-api.md	Adds strict schema checks and producer and relay tests. Documents the contract, data mappings, identity, passive-read behavior, authorization, and route behavior.

Merge Risk: ⚪ Minimal · up to 3a7db

The quota-pool change is mergeable after normal checks. A narrow concurrent-startup timing window may briefly make the endpoint unavailable, but it recovers when identity creation finishes.

Review comments at @src/quota-pool/assemble.ts:
- Line 55: Update assemble.ts to reuse the exported VERSION constant from
management-api.ts instead of calling packageVersion with a duplicate fallback,
ensuring producer.version stays aligned with the management version.
- Line 226: Update the reauth value passed to accountState in the account
assembly flow to depend only on dto.needsReauth === true; do not infer reauth
from dto.hasCredential, so passive reads without credential checks remain
routable.

Review comments at @src/quota-pool/identity.ts:
- Around line 72-73: Update ensureQuotaPoolIdentity to use an exclusive create
when persisting a newly generated identity, preventing replacement of an
identity created by another process. If exclusive creation reports that the file
already exists, reread the persisted identity and memoize that value instead of
the locally generated identity; keep the existing memoization path for a
successful create.

Review comments at @src/server/management/quota-pool-routes.ts:
- Line 17: Update the response construction around jsonResponse so both the
success and error branches pass req and config, preserving status 200 for
success and 503 for errors to ensure generated CORS headers are included.

@codex review — the two identity findings from e1ab5d0 are addressed in 3a7db3e (exclusive no-follow creation; the race loser adopts the winner).

[lidge-jun]

Merged with owner authority per maintainer decision 2026-10-21 (jun): the project owner authorized owner-path (--admin) merges for the pending green PRs after the 2.90.0 release; no second-maintainer approval is available.

Exact-head verification on 3a7db3ee98bb35e11923b47295c4c2da417c528a: all checks completed with no failures, the PR is mergeable, there are no change requests, and no unresolved current Major/Critical/P0/P1 review threads. A local squash of this head onto current dev 561347cca passed typecheck, structure:check, the file-size, import-cycle and test-layout ratchets, and this PR's own tests ( 116 pass 0 fail ). The merge is a squash pinned with --match-head-commit.
