📝 WalkthroughWalkthroughGoogle Antigravity is added to OAuth forced-refresh and 401 replay handling. Refreshed project IDs and routing metadata now propagate through recovery and account-rotation paths. Tests cover refresh, replay, streaming, error sanitization, project validation, repeated 401 responses, and concurrent requests. ChangesGoogle Antigravity OAuth recovery
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to OAuth 401 recovery is covered, but static key-pool recovery may not reliably rotate or terminate after repeated upstream 401 responses. Focused regression tests are needed before relying on this path. Sequence Diagram(s)sequenceDiagram

The rebase is now correct at dbfb3e82a, and the Antigravity allowlist addition remains appropriately narrow. I am withholding security sponsorship for one fail-closed boundary on this exact head.
Both OAuth 401 replay loops spread the refreshed bearer over route.provider and replace project only when refreshed.projectId exists. A project-less Cloud Code Assist snapshot can therefore replay a new bearer with the previous route/config project. Current dev already centralizes the required invariant in applyFailoverSnapshot: for googleMode === "cloud-code-assist", a missing snapshot project must reject the identity replacement instead of retaining another generation or account project. Apply the same guard in both the passthrough and generic adapter 401 replay paths before rebuilding or dispatching.
Please add a negative project-less refresh test for both replay owners, and add one stream: true Responses case that consumes the SSE result and proves exactly one refresh/replay with the fresh bearer and project. The existing non-streaming and concurrency coverage is otherwise strong.
After that new exact head is clean, I can repeat the focused OAuth review and apply maintainer-sponsored. Do not merge this draft head.

Security review approved for exact head fcfe877c7.
The requested fail-closed invariant is now present in both OAuth replay owners before request rebuild or dispatch: a Cloud Code Assist refresh without a project cannot combine the new bearer with the previous route project. The refreshed bearer/project pair is carried together when valid. The allowlist remains exact to google-antigravity, other OAuth providers retain their existing behavior, and the public error does not expose refresh details.
Isolated validation on this head: all 11 Antigravity 401 replay tests pass, including native Responses passthrough, generic adapter, Chat translation, concurrent single-flight, second-401 termination, three project-less negative paths, and a fully consumed streaming replay. TypeScript tsc --noEmit also passes, and protected runtime configuration was not used.
This approval supplies the requested trust-boundary review only. The PR is still Draft and current hygiene/enforce-target checks are red; do not merge until the readiness gate is repaired, the full exact-head CI is green, and the head remains unchanged.

Summary
Closes #3575
Add
google-antigravityto the set of OAuth providers supported by automatic upstream 401 recovery and force-refresh replay (isOAuth401ReplayProviderandFORCE_REFRESH_PROVIDERS), with fail-closed Cloud Code Assist project invariant enforcement.Root Cause
When Google Antigravity OAuth session tokens expire, desynchronize, or are invalidated upstream by Google, upstream API requests fail with 401 Unauthorized. Other OAuth providers (
xai,github-copilot,kiro) automatically intercept upstream 401s, force-refresh the snapshot viaforceRefreshOAuthAccessSnapshot, and transparently replay the request. Forgoogle-antigravity, the absence fromisOAuth401ReplayProviderandFORCE_REFRESH_PROVIDERScaused requests to terminate immediately, returning raw 401 errors to client applications until manual credential re-resolution occurred.Key Changes
