feat(combos): opt-in advisory quota signals for JEV decisions (P1)

[geunwoojun99]

Summary

Adds opt-in, cached advisory quota evidence to the JEV decision backends. This is the separate P1 piece discussed in #6665, built on dev after the P0 shared exchange landed in #6791 and merged (not rebased) with dev at 32a25c85e in 5510a35dc at e6950e03b in fe21c8bea, at 17dbbac08 in 2bef3d3d2, and at 9f34ea78a in c17d0d304. It touches nothing in the exchange itself.

It does not approve or imply later demand-level, custom-level, hint, session-pin or escalation features. Config shape and pin identity decisions stay with the owners; this PR adds no level or pin behavior.

• Dormant by default. Per-Combo decisionQuotaSignals is explicit opt-in. With it unset or off, request bytes and routing are unchanged. Optional decisionQuotaTiers overrides merge with defaults (limited: 70, nearlyExhausted: 90; moderate only when configured). Thresholds must be finite, within 0-100 and strictly ascending.
• Loaded-only evidence. The decision path reads only secret-free, in-memory snapshots published by the existing quota producers (account probes, accepted response headers, collector reports). Reading never resolves credentials, loads auth stores or quota files, probes upstream or starts a refresher. Cold, missing, stale (over 30 minutes), future, invalid or reset-expired evidence is unknown, and unknown ties healthy.
• Credential-bound. Per-account evidence is bound to the credential generation it was observed under, so evidence cannot be attributed to a different credential that reuses an account id. A pool is nearly exhausted only when every usable account is.
• Advisory only. TypeSafe, System One and model backends receive the tier. Hard eligibility, vetoes, cooldowns, allowlists and serving-account selection are unchanged. Outbound quota carries tier, used percentage, window and reset delay only, never account ids or credential fingerprints.
• Credits are not windows. Balance-style credit amounts (for example the Ollama Cloud balance added in fix(quota): read the Ollama Cloud quota from /api/balance #6786) are never advisory windows; only percent windows are projected. A new test covers this.
• Second Anthropic pool excluded. After the multi-instance refactor (feat(anthropic): add anthropic2, an independent Anthropic account pool with a green Pool 2 mark #6743), only the primary anthropic instance publishes or is read. The anthropic2 pool publishes nothing and reads as unknown, even if an account id and credential generation collide with the primary. Covered by a regression test and documented.
• Config, management API and ocx combo set --decision-quota-signals on|off|- / --decision-quota-tiers JSON|- validate, preserve and clear the fields. Docs, owning structure docs and generated CLI references are updated. No GUI controls, timers or background quota warmer.

Out of scope: demand levels, custom level ids, hints, session pins, escalation, rich-state fields and new GUI controls.

Review scope

63 files, +1914/-87 versus dev at 9f34ea78a (git diff --shortstat origin/dev...HEAD at c17d0d304; it was +1915/-87 at 2bef3d3d2 versus dev at 17dbbac08, the one fewer insertion being a doc-comment line of this PR that the latest merge dropped in favor of dev's own comment on the same function; it was +1915/-87 at 2dbba60fe versus dev at e6950e03b, and +1915/-85 at 97016d14b versus dev at 71c4ae3c8, the two extra deletions being the layout-registry compaction in 2dbba60fe), of which 40 production files are +781/-73 (CodeRabbit reported 87.2% docstring coverage on the functions this change touches); the rest is tests, docs and the test-layout registries. Six non-merge commits and four merge commits (git log origin/dev..HEAD lists 10). Five were written on dev at 71c4ae3c8: the feature (acb466773), a review-fix commit (3bb8e7f90) that applies the CodeRabbit findings and adds docstrings, an auth-store isolation hardening commit (2f1f01a97), a Codex account-store isolation hardening commit (51dcbd1eb) and a test-only isolation fix (97016d14b). Then come merge 5510a35dc (dev 32a25c85e; its only textual conflict was src/server/messages-native.ts, see Verification), merge fe21c8bea (dev e6950e03b, no conflicts, no overlap beyond the two layout registries) and 2dbba60fe, a registry-only commit: after the second merge scripts/test-layout/layout.json reached exactly 2000 lines and the file-size ratchet reported it as NEW_OVERSIZED, so the two entries this PR adds there were put on existing lines (1998 lines; no cap, baseline or guard changed). The third merge 2bef3d3d2 (dev 17dbbac08; one textual conflict, see Verification) leaves the registry at 1999 lines, the same count as dev's own file, so this PR adds no registry lines; that is one line under the 2000-line ratchet threshold, which dev itself now sits against. It reconciles with #6791 (no shared-exchange changes), #6743 (per-instance recorders and the account probe moved to anthropic-account-quota.ts), #6786 (credits excluded) and #6792 (no overlapping source files). The fourth merge c17d0d304 (dev 9f34ea78a; one textual conflict, see Verification) adds no registry lines either: the file stays at 1999 lines, equal to dev's own.

Verification

Run locally with the repository's pinned Bun 1.4.0 (checksum-verified standalone binary selected via OCX_TEST_RUNNER_BUN), isolated HOME/temp, and bun install --frozen-lockfile. These results are local; hosted CI has not been confirmed green for this head. Each result below states which commit or tree it was run against: acb466773 is the feature commit, 3bb8e7f90 the review-fix commit on top of it, 2f1f01a97 the auth-store hardening 51dcbd1eb the Codex account-store hardening, 97016d14b the head before the merges, 2bef3d3d2 the previous head (third merge), and c17d0d304 the current head (fourth merge).

• Results at the current head c17d0d304 (fourth merge, dev 9f34ea78a; cached Bun 1.4.0, --no-install, repo preload, the worktree's own node_modules; neither package.json nor bun.lock differs from dev on this PR's side, so no install was run):
  • Conflict: one file, src/server/responses/request-transport.ts. Both sides had added a doc comment above oauthDispatch; dev (Copilot Auto, fix(copilot): negotiate Auto for positively restricted accounts (carry #6472) #6885) also added an owner parameter to its signature. Resolution takes dev's signature and doc comment verbatim. This PR's own edit in that file (passing the credential generation to recordAnthropicAccountQuotaFromHeadersForInstance) auto-merged and is intact. Files both sides touched that auto-merged: scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, structure/dashboard-and-usage.md, structure/providers-and-adapters.md.
  • Semantic review (code read, not a new test): the four dev commits (test: isolate host settings and bound native Windows fixtures #6864, fix(copilot): negotiate Auto for positively restricted accounts (carry #6472) #6885, fix(desktop): judge machine-path-conflict from a fresh logon PATH #6888, fix(logs): keep recognized bare upstream error classes in synthesized terminals #6889) touch no quota, JEV, combo or src/oauth/* source, and no src/codex file except catalog/provider-models.ts. fix(copilot): negotiate Auto for positively restricted accounts (carry #6472) #6885 adds Copilot Auto negotiation to the request transport (a wire/adapter selection and a refusal path); it does not read or publish advisory quota evidence, and the anthropic quota-recording call in the same function is unchanged. No source change beyond the conflict resolution was needed and none was made.
  • The 8 quota/JEV and isolation files (tests/routing/jev-quota-*.test.ts, tests/server/server-jev-model-quota-budget.test.ts, tests/oauth/oauth-store-quota-isolation.test.ts, tests/codex-integration/codex-account-store-quota-isolation.test.ts): 65 pass, 0 fail.
  • tests/codex-integration/codex-account-store*.test.ts (3 files): 94 pass, 0 fail. All 45 tests/oauth/*.test.ts files plus those 3, each run in its own process: 922 pass, 0 fail. In one single process the same 48 files give 911 pass, 11 fail (oauth refresh and status cases; I did not re-compare the names with a clean dev run at this head, but the count matches the pre-existing cross-file failure documented below for 71c4ae3c8), and every one of those files passes when run alone.
  • tests/test-layout.test.ts, tests/test-layout-tooling.test.ts, tests/ci-workflows/ci-structure-gate.test.ts, file-size-ratchet.test.ts, structure-ssot.test.ts, fixture-dir-uniqueness.test.ts, plus tests/responses/responses-core-modules.test.ts and tests/providers/github-copilot/github-copilot-auto.test.ts (files dev changed that overlap this PR's changed source): all pass, 0 fail.
  • The three tsc commands from ci.yml: exit 0, no diagnostics. structure-ssot, privacy-scan, file-size-ratchet and generate-ocx-skill-surface --check: pass. git diff --check origin/dev...HEAD: clean. scripts/test-layout/layout.json is 1999 lines, equal to dev's file and under the 2000-line threshold; no cap or baseline changed.
  • Not re-run at this head: the wider per-directory and full-suite runs, the tests/ci-workflows/ directory as a whole, the docs-site build, and hosted CI. The earlier blocks were measured at the heads they name.
• Results at the previous head 2bef3d3d2 (third merge, dev 17dbbac08; same Bun and flags):
  • Conflict: one file, structure/gui-and-management-api.md. dev moved the reset-grants devlog link from devlog/_plan/ to devlog/_fin/ on a row adjacent to the Combos row this PR edits to mention decisionQuotaSignals/decisionQuotaTiers. Resolution keeps dev's _fin link and this PR's Combos row. No source file conflicted; scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, src/codex/main-account.ts, src/server/responses/jev-model-invoke.ts, src/types/config.ts and several structure docs auto-merged.
  • Semantic review (code read, not a new test): dev's changes to files this PR also touches are src/codex/main-account.ts (fix(codex): never discard a rotated native-main refresh token on cancel #6859, the rotated refresh token is persisted before honoring cancellation; this PR's edit there is the quota-generation hook, in a different region), src/server/responses/jev-model-invoke.ts (fix: release active-turn admission when the client cancels #6850, tryAdmitTurn(undefined, signal); the PR's quota change is in request construction, not admission) and src/types/config.ts. Codex pool selection gained failureWindowSteersNewThreads (fix(codex-pool): stabilize account health and reuse WS per thread under concurrency #6860); it filters accounts by failure history and does not read or publish advisory quota evidence. No src/oauth or auth-store change from dev overlaps the PR's publication hooks (comment-only edits in src/oauth/index.ts and types.ts). No source change beyond the conflict resolution was needed and none was made.
  • The 8 quota/JEV and isolation files (tests/routing/jev-quota-*.test.ts, tests/server/server-jev-model-quota-budget.test.ts, tests/oauth/oauth-store-quota-isolation.test.ts, tests/codex-integration/codex-account-store-quota-isolation.test.ts): 65 pass, 0 fail.
  • tests/codex-integration/codex-account-store*.test.ts (3 files): 94 pass, 0 fail. tests/oauth (45 files) with --parallel: 828 pass, 0 fail; in a single process the same directory gives 817 pass, 11 fail, the same count as the pre-existing cross-file failure documented below for 71c4ae3c8 (names not re-compared at this head), and each of the 45 files passes when run alone.
  • tests/test-layout.test.ts, tests/test-layout-tooling.test.ts, tests/ci-workflows/fixture-dir-uniqueness.test.ts and tests/ci-workflows/structure-ssot.test.ts: 72 pass, 0 fail.
  • The three tsc commands from ci.yml: no diagnostics. structure-ssot, privacy-scan, file-size-ratchet, generate-ocx-skill-surface --check and git diff --check origin/dev...HEAD: pass.
  • Not re-run at this head: the wider per-directory and full-suite runs, the tests/ci-workflows/ directory as a whole, the docs-site build, and hosted CI. The "Results at head 2dbba60fe" block below was measured at that head against dev e6950e03b.
• Results at the first merge 5510a35dc (merge of dev 32a25c85e; the later results are listed after this block; cached Bun 1.4.0, --no-install, repo preload, the worktree's own node_modules; the merge changes neither package.json nor bun.lock, so no install was run):
  • Conflict: one file, src/server/messages-native.ts, at the native send helper. Resolution keeps this PR's doc comment and takes dev's widened recovery union (adds "oauth-401", from fix(anthropic): eject an OAuth account whose access token was revoked #6832). Files auto-merged that both sides touched: src/codex/auth-context.ts, src/codex/main-account-cache.ts, src/oauth/store.ts, plus docs, structure and layout registries.
  • Semantic review (code read, not a dedicated new test): dev's main-login dispatch fence (fix(quota): record main-login responses under the observed main credential #6830: captureMainQuotaDispatch, renewMainQuotaDispatchForAttempt) builds its writer through captureMainQuotaWriter, which still records the credential generation this PR's mainDecisionQuotaWriterGeneration checks, and renewal copies share that writer object. Main responses publish through applyAccountQuotaFromUpstreamHeaders, which keeps advisory evidence opt-in (decisionRaw only for a valid observation); a dispatch captured without an observed credential reads as unknown, not as evidence. fix(anthropic): eject an OAuth account whose access token was revoked #6832 (revoked OAuth token ejection) touches src/oauth/store.ts only in markAccountNeedsReauthIfGeneration, away from this PR's roster hooks. No source change beyond the conflict resolution was needed and none was made.
  • Quota/JEV tests (tests/routing/jev-quota-*.test.ts, tests/server/server-jev-model-quota-budget.test.ts) plus tests/oauth/oauth-store-quota-isolation.test.ts and tests/codex-integration/codex-account-store-quota-isolation.test.ts: 65 pass, 0 fail (8 files).
  • Adjacent directories, one bun test per directory with --parallel=4: tests/adapters/anthropic 1187 pass/0 fail, tests/oauth 828/0, tests/providers 6191/0, tests/responses 4577/0, tests/routing 1423/0, tests/usage 998/0, tests/claude-integration 1882 pass/2 fail, tests/cli 4268/5 fail, tests/codex-integration 7782/7 fail, tests/server 4015/2 fail. The failures were in 9 files (claude-desktop-remote-hub, claude-picker-runtime, cli-help, cli-models-reasoning, sibling-home-client-sync, codex-shim-overlay-readiness, codex-shim-path-readiness, local-management-direct-transport, subagent-model-force-api). Re-running those 9 files together: 158 pass, 14 fail at 5510a35dc, and 158 pass, 14 fail with identical names on a clean dev 32a25c85e checkout. The parallel directory runs showed 16 failures in total, so two of them were load-dependent; I did not isolate the cause of the 14 (Docker detection and running as root are plausible, as one cli-help failure shows a Docker-detected message).
  • tests/test-layout.test.ts, tests/test-layout-tooling.test.ts and tests/ci-workflows/: 1545 pass, 1 fail (dev version bump rule > an unwritable target fails closed), which also fails on clean dev 32a25c85e.
  • bun x tsc --noEmit, tsc -p tests/tsconfig.doctor-service-memory-contract.json and the docker-smoke tsc command from ci.yml: exit 0. structure-ssot, privacy-scan, file-size-ratchet, generate-ocx-skill-surface --check and git diff --check origin/dev..HEAD: pass.
  • Results at the previous head 2dbba60fe (after the second merge and the layout fix), run with the same Bun and preload: the 8 quota/JEV and isolation test files: 65 pass, 0 fail; tests/ci-workflows/, tests/codex-integration/codex-account-store*, tests/responses/responses-spill-admission-headroom.test.ts and the layout tests: 1541 pass, 1 fail (the same dev version bump rule > an unwritable target case, which also fails on clean dev); the three tsc commands: exit 0; structure-ssot, privacy-scan, file-size-ratchet (it failed at fe21c8bea on layout.json and passes at 2dbba60fe), generate-ocx-skill-surface --check and git diff --check: pass. The wide per-directory and 9-file comparisons above were not repeated at this head; the second merge only adds dev's e6950e03b (spill headroom in the responses path, structure doc, tests), which shares no source file with this PR.
  • Not re-run at this head: the docs-site build, the full-suite runs and the 242-file import-connected run described below; those figures belong to the earlier heads they name. Hosted CI is not confirmed.
• bun x tsc --noEmit at 3bb8e7f90: exit 0. bun x tsc --noEmit -p tests/tsconfig.doctor-service-memory-contract.json and the docker-smoke tsc command from ci.yml were run at the previous head acb466773: exit 0; the review-fix commit changes one default parameter, one local variable and comments only.
• Focused and import-connected tests: every *.test.ts that references the touched quota/JEV/account/auth-context modules (242 files) via bun scripts/test.ts: 7294 pass, 4 skip, 0 fail. This run predates the final review-fix commit 3bb8e7f90 (its log finished before that commit was made) and was not repeated on the committed head. A later 535-file run (the 242-file set plus tests/cli and tests/server/management, 4x parallel), whose log finished about 10 seconds before the 3bb8e7f90 commit was made, reported 12875 pass, 43 skip, 6 fail, 3 errors; the 6 failures (two CLI-help tests and four live-audio failures, one name three times) also fail on a clean dev checkout here. The cause was not isolated; environment-dependent causes such as Docker detection or running as root are plausible.
• Re-run at head 3bb8e7f90 for this description: the quota/JEV tests (tests/routing/jev-quota-*.test.ts, tests/server/server-jev-model-quota-budget.test.ts): 60 pass, 0 fail. Adjacent: tests/adapters/anthropic/anthropic-instance-*.test.ts, tests/providers/provider-anthropic-instance-quota.test.ts, tests/test-layout.test.ts, tests/test-layout-tooling.test.ts, tests/ci-workflows/file-size-ratchet.test.ts: 190 pass, 0 fail. An earlier 190-pass run of the same adjacent set predated both commits. The new test file is registered in both layout registries; no cap or guard was weakened.
• bun run structure:check, bun run privacy:scan, git diff origin/dev..HEAD --check and the layout/ratchet tests (28 pass) at 3bb8e7f90: pass. bun run skill:surface:check was run at acb466773: pass.
• Docs: bun install --frozen-lockfile then bun --bun run build in docs-site at acb466773: 569 pages, 79,226 internal links checked. The review-fix commit touches no docs. No supported-Node build was run.
• Red/green: removing the primary-only publication guard turns two anthropic2 tests red. Note the guard mutation only went red after the test forced the same account id and credential generation across pools; with distinct generations the existing generation binding already prevented the collision. Restored, all pass. The review-fix commit also adds a regression test (a live main writer that omits explicit decision evidence publishes no codex-main window) that failed before the change and passes after.
• Hardening at 2f1f01a97 (found by a verifier reading the diff): in loadAuthStoreInternal, roster publication ran inside the parse try, so a publication failure would have reached the invalid-config backup path: it wrote a spurious auth.json.invalid-* backup and then threw (the load returned an empty store only if the second, fallback publication in the catch succeeded). Publication now runs after the parse, the auth-owned publisher never throws (on failure it withdraws the Anthropic roster so the pool reads as unknown, not stale), and persist is covered by the same guard, so a failed publication cannot fail or undo an auth write. New tests/oauth/oauth-store-quota-isolation.test.ts (2 tests, registered in both layout registries): red before (injected publication failure propagated), green after. At 2f1f01a97, run locally with the pinned Bun 1.4.0: tests/routing/jev-*.test.ts, routing-policy-pool-quota.test.ts and tests/oauth/ (run before the test file was renamed for the layout registry): 1041 pass, 0 fail; renamed new test plus layout tests: 21 pass, 0 fail; tsc --noEmit, structure-ssot, privacy-scan, file-size-ratchet and git diff --check: pass. The 242-file run and the full-suite numbers below predate this commit and were not repeated.
• Hardening at 51dcbd1eb (same defect on the Codex side, found by a verifier probe that confirmed a spurious codex-accounts.json.invalid-<ts> backup and a thrown error): loadCodexAccountRecordStore published the roster inside the parse try; it now parses inside the try and publishes after it. publishCodexDecisionQuotaRoster (src/codex/store-decision-quota.ts) never throws and withdraws the codex roster on failure, which also covers the call after atomicWriteFile in persist. publishMainDecisionRoster in src/codex/main-account-cache.ts (called from the presence/usability/credential state transitions, with no containment of its own) is guarded the same way for codex-main, so a publication failure cannot abort a cache state change. New tests/codex-integration/codex-account-store-quota-isolation.test.ts (3 tests: load, persist, main presence; registered in both layout registries): all three fail on the previous source (the injected publication failure propagates) and all pass after. At 51dcbd1eb, with the cached Bun 1.4.0 binary: bun x tsc --noEmit exit 0; tests/routing/jev-quota-*.test.ts and tests/server/server-jev-model-quota-budget.test.ts (60 tests), tests/codex-integration/codex-account-store*.test.ts (94 tests) and the files referencing main-account-cache each run per file: 0 fail; every tests/oauth/*.test.ts run per file: 0 fail; layout tests (19) pass; structure-ssot, privacy-scan, file-size-ratchet and git diff --check pass. Running tests/oauth together with the quota/codex files in one bun test process gave 11 failures in oauth refresh/status tests that pass when each file runs alone. Investigated: those 11 are pre-existing and not caused by this PR. Running all tests/oauth/*.test.ts in one process (cached Bun 1.4.0, --no-install, repo preload) gives the identical 11 failures (oauth refresh hardening needsReauth cases, OAuth status privacy needsReauth, one CLI Antigravity live-update case) on a clean origin/dev 71c4ae3c8 tree and on this branch. The wider combined run (every tests/oauth/*.test.ts, every *quota*.test.ts, every tests/codex-integration/codex-*.test.ts, one process) has the same 50 distinct failing test names on origin/dev and on this branch at 97016d14b (50 to 51 failures per run depending on the exact file list; the distinct-name sets match); I did not root-cause those pre-existing cross-file failures. The same combined run did expose one defect in this PR's own new test: tests/routing/jev-quota-codex-reset.test.ts failed (5 pool WHAM retains invalid reset cases, and all 20 tests when run after tests/providers/muse-passive-quota-cache.test.ts) because an earlier file's incomplete-context reconcileStateGeneration leaves the Codex quota fence ahead of the shared generation, so default-generation writers are discarded; the WHAM test also hardcoded writerGeneration: 0. Fixed in 97016d14b (test-only: complete empty reconciliation in beforeEach, real captureConfigGeneration()); after it the combined run's failing set equals origin/dev's. Hosted CI is still unconfirmed.
• Full-suite status: not green here, and not identical to a clean dev control. Repository policy permits a documented full-suite exception; this is the evidence, stated without rounding.
  • bun scripts/test.ts --changed=dev at acb466773 (1668 files): 35554 pass, 110 skip, 40 fail (38 distinct names), 3 errors.
  • Control: a clean dev checkout at 71c4ae3c8 (no changes), same pinned Bun and deps, full bun scripts/test.ts (2156 files): 41940 pass, 118 skip, 48 fail (46 distinct names), 3 errors.
  • This branch at 3bb8e7f90, full bun scripts/test.ts (2162 files): 42026 pass, 118 skip, 22 fail (20 distinct names), 3 errors. 17 of those 20 names also fail in the clean dev full run; the other 3 (web-search sidecar settings/streaming tests) pass when run in isolation on both this branch and clean dev (85 pass).
  • The failing sets are not deterministic: they differ between runs on both dev and this branch (38, then 20 names here; 46 on dev), so the wide runs cannot be compared name-for-name. In the 10-file group that holds most of the failures (CLI help, live-audio, codex-shim PATH readiness, native Codex/Grok toggles, service ownership/SQLite-home/service tests, subagent-force-api), serial and 4x-parallel runs give the same failing-name set on this branch and on clean dev (13 names serial, 14 parallel). The toggle, service-ownership and SQLite-home names that failed only in the wide --changed=dev run pass in that group on both trees.
  • tests/lab/lab-live-review-regressions.test.ts and tests/cli/cli-update-restart-home.test.ts failed or errored only under the wide --changed=dev run; together they pass (16 pass) in isolation on this branch and on clean dev. Neither failed in the clean dev full run or in the later full run on this branch, so the identical-set claim does not hold for them and I attribute those failures to parallel load without proof.
  • No failing test is in a file this change touches. Environment-dependent causes (Docker detection, running as root, localhost IPv6, shared state under parallel load) are plausible but not established for every name.
• A wider test-type check (all test files, not CI's) reports one diagnostic in tests/helpers/anthropic-instance-fixture.ts (TS2352), an existing dev helper that this PR does not modify.

Not checked: hosted CI, cross-platform runs, live provider or hosted TypeSafe/model calls, and the sidecar service path (it publishes no decision evidence, so nothing was exercised there).

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. Explicit maintainer review and maintainer-sponsored requested, because this PR changes src/oauth/store.ts, src/oauth/anthropic-model-quota.ts, two new src/oauth/ files and src/codex/auth-context.ts (+47/-11 lines across those five files, the ones the hygiene gate listed), and, since 51dcbd1eb, the Codex credential-store publication hooks src/codex/account-store.ts, src/codex/main-account-cache.ts and the new src/codex/store-decision-quota.ts (+72/-5; +119/-16 across all eight files; see the PR comment). The producers publish into a credential-bound, loaded-only in-memory evidence boundary (credential generation binding, no credential/file/keychain reads on the decision path, secret-free outbound payload, anthropic2 exclusion). Please review that boundary.

Review readiness

• Required local validation passed with its scope documented. (Targeted, typecheck, layout, structure, privacy and docs checks pass; the full suite is red on both this branch and clean dev with non-identical, load-dependent failing sets, documented above as a full-suite exception request. Not ticked because the failing-name sets are not identical to the control.)
• Branch contains the latest upstream dev (merged 32a25c85e, e6950e03b, 17dbbac08 and then 9f34ea78a, head c17d0d304, on 2026-10-10; the first, third and fourth merges each had one textual conflict, no rebase; origin/dev was at 9f34ea78a when fetched before the merge).
• All correct Codex and CodeRabbit findings are fixed. (CodeRabbit's 2 findings on acb466773 are fixed in 3bb8e7f90 with replies and resolved threads; its re-review of the new head reports no actionable comments, and CodeRabbit reports docstring coverage of 87.2% (125 functions) against its 80% threshold. No Codex review has been posted on this PR.)
• Ready-for-review confirmation. (The author considers the code ready for review. The PR is currently a draft: the repository gate re-drafted it with unsponsored_surface because it touches src/oauth/* and src/codex/auth-context.ts, so it stays a draft until a maintainer reviews that surface and applies maintainer-sponsored. The [Feature]: Demand-level routing for JEV combos — orchestrator-chosen levels, per-session pinning, probability escalation (opt-in series on #6364) #6665 owner questions on config shape and pin identity remain open; this PR does not decide them.)

Summary by CodeRabbit

• New Features

  • JEV Combos can optionally include advisory quota signals, allowing decision backends to consider usage levels and reset times. Signals are off by default, and quota thresholds can be customized.
  • Configure or clear quota settings through the CLI or API. Omitted settings are preserved during updates; switching away from JEV removes them.
  • JEV decisions and usage summaries can report quota-tier counts and the selected tier. Requests that exceed size limits can proceed without quota details.

• Documentation

  • Added guidance on quota signals, configuration, data handling, and update behavior.

Walkthrough

This change adds opt-in advisory quota signals to JEV Combos. It publishes loaded provider quota evidence for use in decisions, adds configuration and CLI/API update handling, and records bounded quota summaries. Model requests can omit quota data when it exceeds the request-size limit.

Changes

JEV advisory quota signals

Layer / File(s)	Summary
Quota policy configuration and updates src/combos/types.ts, src/types/config.ts, src/cli/combo.ts, src/cli/combo-result.ts, src/cli/capabilities-agents-routing.ts, src/server/management/combo-routes.ts, docs-site/src/content/docs/guides/combos.md, docs-site/src/content/docs/reference/cli/agents.md, docs-site/src/content/docs/reference/configuration/routing.md, skills/ocx/references/*, structure/cli-management.md, structure/config.md, structure/gui-and-management-api.md, tests/routing/jev-quota-config.test.ts	JEV configuration accepts an optional signal switch and validated quota-tier thresholds. CLI and API updates support clearing settings and preserve omitted settings in documented update cases. Switching strategies removes quota settings.
Loaded quota snapshots and account rosters src/providers/quota-decision-snapshot.ts, src/providers/api-key-resolve.ts, src/oauth/store*, src/oauth/store-decision-quota.ts, src/codex/account-store.ts, src/codex/store-decision-quota.ts, src/codex/main-account-cache.ts, src/codex/main-account.ts, src/codex/account-runtime-state.ts, src/oauth/anthropic-model-family.ts, src/oauth/anthropic-model-quota.ts, structure/providers/anthropic-account-pool.md, structure/providers/openai-accounts.md, structure/runtime.md	The in-memory snapshot tracks bounded quota windows, account rosters, generations, and usability. Account-store changes publish rosters. Credential and configuration changes invalidate or retire evidence.
Provider quota projection and publication src/providers/quota-decision-publication.ts, src/providers/quota/anthropic-decision-windows.ts, src/providers/quota/account-cache.ts, src/providers/quota/anthropic-*, src/providers/quota/report-cache.ts, src/providers/quota/vendor-probes-oauth.ts, src/providers/quota.ts, src/providers/quota-routing-cache.ts, src/codex/quota.ts, src/codex/auth-api/main-account-probe.ts, src/codex/auth-context.ts, src/server/messages-native.ts, src/server/responses/request-transport.ts, tests/routing/jev-quota-publication.test.ts, tests/routing/jev-quota-codex-reset.test.ts, tests/routing/jev-quota-anthropic2.test.ts	Quota producers publish provider-specific windows with observation times and reset data. Publication uses credential generations and commit checks. Tests cover reset handling, stale evidence, account usability, and isolation of the primary Anthropic pool from anthropic2.
Quota-aware JEV decisions and request limits src/combos/jev-quota-config.ts, src/combos/jev-quota.ts, src/combos/jev-quota-route.ts, src/combos/jev.ts, src/combos/jev-model-backend.ts, src/combos/jev-model-request.ts, src/server/responses/core-combo.ts, src/server/responses/jev-model-invoke.ts, src/usage/jev-stats.ts, tests/routing/jev-quota-signals.test.ts, tests/server/server-jev-model-quota-budget.test.ts, structure/providers/jev-decision.md	JEV classifies loaded quota evidence and adds signals only when enabled. Decision requests and summaries omit account identifiers. If quota enrichment exceeds the byte limit, model requests can be rebuilt without quota data. Persisted summaries contain bounded tier counts and the selected tier.

44-49: 🔒 Security & Privacy

apiKeyPool does not create a separate active credential path. provider.apiKey is the active pool entry and is the value resolved by resolveProviderApiKey. Therefore, a valid single-entry pool has an apiKey, and its credential version is included in keyPolicy. A pool-only provider has no active credential for routing, so the claimed rotation path is not established.

src/providers/api-key-resolve.ts-105-110 (1)

105-110: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Credential observation runs on every key resolution.

resolveProviderApiKey now computes two SHA-256 digests on every call. Callers include cacheKey() in report-cache.ts, which runs for every provider on each quota read, and the request routing paths. The cost per call is small. It also adds digest work on paths where the decision quota opt-in is off. Consider skipping observeDecisionKeyCredential until at least one key quota has been published, for example by checking keys.size.

Maintainer sponsorship request for the unsponsored_surface hygiene finding.

The gate flags five files, and the enforce-target failure has the same cause (PR quality gate failed: unsponsored_surface in every failed run, including the reruns after body edits). Nothing else is failing. All of the changes are credential-bound publication of loaded-only quota evidence for the opt-in decisionQuotaSignals feature, and none changes how credentials are read, stored or selected:

• src/oauth/store.ts (+9/-2): after loadAuthStoreInternal() and persist(), call publishAuthDecisionQuotaRoster(store).
• src/oauth/store-decision-quota.ts (new, 12 lines): projects the loaded store into a secret-free roster of account id, usable flag and a SHA-256 digest of the credential. The digest uses the same inputs as the existing credentialGeneration(). No token or credential value leaves the module.
• src/oauth/anthropic-model-family.ts (new, 8 lines) and src/oauth/anthropic-model-quota.ts: the pure anthropicModelFamily() regex is moved out unchanged and re-exported, so the decision path does not import the credential reader.
• src/codex/auth-context.ts (+6/-3): the reserve capability read already parsed ordinary usage; it now also hands that parsed observation to the evidence cache when it is a valid history observation.

These hooks have to sit with the auth store and the main-account reader, because the evidence is bound to the credential generation under which it was observed. I did not find a smaller seam that keeps that binding without having the decision path read the auth store, which this PR deliberately avoids. I did not split these files into a separate PR, because they publish into src/providers/quota-decision-snapshot.ts, which is introduced here, so the pieces would not be reviewable or testable apart.

Could a maintainer review these files and, if it looks right, apply maintainer-sponsored? Covered by tests/routing/jev-quota-publication.test.ts, jev-quota-anthropic2.test.ts and jev-quota-codex-reset.test.ts; at head 3bb8e7f90 the quota/JEV tests (60) and the adjacent anthropic-instance/layout tests (190) pass locally. The description now states which commit each local result was run against, and it lists the full-suite exception in detail. I left the local-validation box unticked on purpose, since the full suite is not identical to a clean dev run.

[geunwoojun99]

Pushed 2f1f01a97: hardening so advisory quota-roster publication can never affect auth-store loading or persistence. Previously a publication failure inside loadAuthStoreInternal's parse try routed into the invalid-config backup path: it wrote a spurious auth.json.invalid-* backup and then threw (the load returned an empty store only if the second, fallback publication succeeded). Publication now runs after the parse, the publisher never throws (it withdraws the roster on failure), and a regression test covers both load and persist (red before, green after). Validation details are in the description; still Draft pending sponsorship.

Update: pushed 51dcbd1eb, the same hardening on the Codex side. loadCodexAccountRecordStore had the same coupling (a verifier probe confirmed a spurious codex-accounts.json.invalid-<ts> backup and a thrown error). It now publishes after the parse, publishCodexDecisionQuotaRoster never throws and withdraws the roster on failure (covering persist), and publishMainDecisionRoster in src/codex/main-account-cache.ts is guarded the same way. Regression tests for load, persist and main presence are in tests/codex-integration/codex-account-store-quota-isolation.test.ts; all three fail on the previous source and pass now. Reviewable surface for sponsorship is now +47/-11 across the five files the gate listed, plus +72/-5 in three Codex credential-store files (+119/-16 across eight). Counts versus origin/dev: 63 files, +1909/-85.
