Summary

Carries #7442 by @nordz0r onto the current dev tip and resolves its remaining CHANGES_REQUESTED blocker. Refs #7441.

Antigravity is an OAuth provider, so publishDecisionKeyQuota dropped its quota and every JEV target on it read unknown even while the Cla weekly bucket sat at 100%. With decisionQuotaSignals: true, JEV now sees the Gem and Cla five-hour and weekly buckets from a fresh authenticated probe of the sole active OAuth account:

google-antigravity/claude-sonnet-5-5   quota: unknown  ->  nearly_exhausted (100%, weekly)
google-antigravity/gemini-3.8-flash    quota: unknown  ->  healthy (36%, 5h)

The two carried commits (authored by NorD, cherry-picked unchanged) add the receipt-bound evidence path. The probe captures an opaque receipt, so display reports and direct key publication cannot create evidence. Auth-store transitions such as credential, project, login, selection or roster changes withdraw it. A family (gem | cla) on DecisionQuotaWindow is matched against the resolved native gemini- / claude- model ID. Per-model rows and Argon stay display-only. Account selection, hard eligibility and fallback are unchanged.

The carry commit fixes the open blocker. A renamed Google cloud-code-assist row passed antigravityQuotaEligible. The collector then probed the canonical google-antigravity credential for that row too, and JEV read account A's windows for a row that inference resolves from store[renamed]. Now:

  • eligibility requires the canonical google-antigravity OAuth store key (ANTIGRAVITY_OAUTH_STORE_KEY)
  • fetchAntigravityQuota reads credential, token and account set by the provider name it was called with, the same key getValidAccessTokenSnapshot(route.providerName) uses
  • the collector probes only the canonical row, so the canonical credential is probed once per collection

jevChoiceEfforts moves byte-for-byte (plus one comment) from src/server/responses/core-combo.ts into the new sibling src/server/responses/jev-combo-choice.ts. core-combo.ts goes from 1418 lines on dev to 1395, and the new module is registered in the responses-core inventory.

The second carry commit keeps the fetchAvailableModels fallback out of family evidence. When retrieveUserQuotaSummary fails, that fallback labels the first matching model's counter Gem/Cla. The mapper used to turn that row into a five-hour family window with a fresh observedAt. Decision windows now come only from the summary endpoint. A fallback result keeps its receipt with no windows, so the same owner's summary windows survive with their original clocks.

Decisions

  • Restrict to the canonical store key instead of supporting renamed rows. Inference for a renamed row calls getValidAccessTokenSnapshot("renamed"). That reads store["renamed"] and needs OAUTH_PROVIDERS["renamed"], which does not exist, and ocx login only accepts registered names. A renamed Antigravity OAuth row therefore cannot authenticate inference at all, so there is no account whose quota could truthfully be published for it. It reads unknown, which ties healthy and is the documented safe default. The probe also reads by the provider name, so a later widening of eligibility cannot reopen the cross-account path.
  • Docs and structure updated (docs-site/.../guides/combos.md, structure/providers/jev-decision.md). Both previously promised renamed-instance support.

Review threads

  • Ingwannu CHANGES_REQUESTED at 6f9a111d7 and CodeRabbit src/providers/quota.ts:127 (bind to the inference store key): fixed as described above. A two-store regression gives each account a different quota and covers a missing renamed store, rows with and without explicit CCA mode, and duplicate rows (the canonical bearer is probed once and the renamed bearer never). It fails 4/4 on the carried head and passes after the fix.
  • CodeRabbit src/providers/quota/antigravity.ts:375 on this PR (models fallback becomes family evidence): fixed in 09e1cafba, with regression a models-endpoint fallback naming a family never becomes or restamps family evidence (red without the source check, green with it).
  • CodeRabbit quota-decision-snapshot.ts (require adapter === "google"): not changed. It is outdated, and effectiveGoogleMode already returns null for any non-Google adapter. The carried {"adapter":"openai-chat"} replacement test covers it. The reviewer confirmed this thread targets superseded code.
  • CodeRabbit report-cache.ts (retain previous family windows on an empty refresh): not changed. It is outdated, and replaceAntigravityQuotas already retains same-owner omitted family windows with their original clocks (test display-only refresh retains same live producer's original windows). The reviewer also confirmed this one is superseded.

Verification

All test runs used an isolated home (HOME, CLAUDE_CONFIG_DIR, OPENCODEX_HOME under mktemp -d) and the pinned Bun 1.4.3 runner (OCX_TEST_RUNNER_BUN).

  • bun test on 15 focused files (tests/routing/jev-quota-{antigravity,signals,publication,activation,anthropic2,codex-reset,core-boundary}.test.ts, tests/server/server-jev-{combo-e2e,model-quota-budget}.test.ts, tests/providers/provider-antigravity-{model-quota,quota-retry}.test.ts, tests/responses/responses-core-modules.test.ts, tests/test-layout{,-tooling}.test.ts, tests/lab/core-lab-boundary.test.ts): 237 pass / 0 fail on the final head. tests/providers/provider-quota.test.ts, tests/server/account-import-project-fallback.test.ts and tests/codex-integration/combos.test.ts also import the Antigravity quota module: 273 pass / 0 fail.
  • Red→green: with only the src/providers store-key fix reverted, the new two-store regression fails 4/4. With only the summary-source check reverted, the fallback regression fails. With both fixes, jev-quota-antigravity.test.ts passes 30/30.
  • bun run test:changed (merge base 516aaaaf8, at 3078c38eb): 42885 pass / 108 skip / 0 fail, 1980 files, exit 0. The final commit changes only fetchAntigravityQuota's window source and one test; the focused set above covers every file that imports that module.
  • bun run typecheck: clean on the final head.
  • bun run structure:check: passed. bun run privacy:scan: passed.
  • Windows-sensitive: yes, through the tests/helpers/** path filter (the responses-core inventory entry). The marker scan of added src/tests lines finds 0 markers. Cross-platform CI lane=all is dispatched on exact head 09e1cafba (run 39842743071).
  • Not run: full bun run test (test:changed already covered 1980 files because core-combo.ts is widely imported), the docs-site build (only one paragraph of prose changed), and live measurement against a real Antigravity account.

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. The OAuth credential lookup is narrowed to the provider's own store key, and no credential value, token or account identifier is logged or published. Evidence carries only a one-way digest of the credential generation.

NorD and others added 3 commits October 23, 2026 04:15
Antigravity is OAuth, so publishDecisionKeyQuota dropped its windows and JEV read every target as unknown. Publish the Gem/Cla family buckets from the collected report, bind them to the model family in jevQuotaSignalFromWindows, and keep per-model rows display-only.
…e key

A renamed Google cloud-code-assist row passed antigravityQuotaEligible, so the
collector probed the canonical google-antigravity credential on its behalf and
JEV read account A's Gem/Cla windows for a row that inference resolves from
store[renamed] (which cannot authenticate: no OAuth definition under that name).

Eligibility now requires the canonical google-antigravity store key, the quota
probe reads its store by the provider name inference uses, and the collector
probes the canonical credential once. A two-store regression covers different
accounts and quotas, a missing renamed store, and duplicate rows.

The JEV choice helper moves from core-combo.ts to the jev-combo-choice.ts
sibling so core-combo.ts shrinks instead of growing.

📝 Walkthrough

The change adds Antigravity OAuth quota evidence for JEV. It ties observations to authenticated probes, account ownership, and provider configuration. JEV uses each candidate’s resolved native provider and model identity to select matching quota families.

Changes: Antigravity quota evidence

The Antigravity probe receives provider configuration and can attach receipt-bound Gem and Cla windows to its report. The report cache publishes collected key and OAuth observations together. Tests cover accepted windows and probe changes during collection; the guide documents when evidence may be used.

JEV candidates carry a resolved quota identity when quota signals are enabled. Family-tagged windows are matched to native gemini-* and claude-* models; unknown identities produce unknown tiers. Routing tests and an end-to-end test cover the resulting signals.

Merge Risk: 🔵 Low · up to 3078c

When the quota-summary probe fails, JEV may use one model’s counter as family quota evidence and change its advisory routing choice. The change is mergeable with owner awareness, though restricting publication to summary-derived windows is preferable.

When retrieveUserQuotaSummary fails, the fetchAvailableModels fallback labels
the first matching model's counter "Gem"/"Cla". antigravityDecisionWindows
mapped that row to a five-hour family window with a fresh observedAt, so one
model's counter became family evidence and restamped the retained summary
window. Decision windows now come only from the summary endpoint; a fallback
result keeps its receipt with no windows, so same-owner summary windows survive
with their original clocks.
