transport chunk: update the stream parsing logic around the payload-size checks
to measure UTF-8 bytes since the last frame delimiter, retain only incomplete
frame bytes between reads, and allow multiple individually valid frames in one
chunk. Add a regression test covering multiple sub-cap frames delivered in one
oversized chunk.
In `@src/providers/antigravity-quota.ts`:
- Around line 169-187: Update fetchHostQuota to parse each fulfilled quota RPC
independently instead of returning null when either Promise.allSettled result
rejects; preserve any Gemini or weekly quota window produced by the successful
result and return a ProviderQuota whenever either window exists, while retaining
the existing AntigravityQuotaRpcError retry behavior. Add a regression test
covering retrieveUserQuota success with retrieveUserQuotaSummary returning 404.

- Around line 3985-4033: Update the Google HTTP adapter’s cloud-code-assist 429
handling to call recordAntigravityCooldown with the classified cooldown reason
before returning the final response, using the provided antigravityAccountId.
Add a handleResponses regression test covering account selection, token/project
rebinding during failover, and enforcement of the three-failover limit.

리뷰 · 우선순위 52 / 80#1916 슬라이스 3/4다. Claude-on-CCA가 이 슬라이스의 와이어는
같은 diff에 테스트는 wire, adapter, sse-frame-cap, quota다. 전체 스위트 숫자는 설명에 없다. 보안 질문은 Claude beta 헤더와 Bearer가 CCA 호스트로 나가는 기존 경로를 더 dens하게 만드는 일이다. 새 OAuth 모듈은 이 목록에 없다. 해결방안#2068이 먼저 안정된 뒤에 isolated compare만 리뷰하고 머지하라. docs 칸이 비어 있었으니 Claude CCA 계약을 가이드 한 절에 적어라. #2071이 이 위에 쌓이므로 이 와이어를 먼저 고정해야 failover 리뷰가 의미가 있다. 이 댓글은 grok-bot이 작성했습니다 |

messagesToGeminiFormatis shared by all three google modes. Line 164 now applies the repair toai-studioandvertexrequests as well. The justification insrc/adapters/google-antigravity-tools.tsLines 19-23 is CCA-specific: CCA translates Gemini function calls into Anthropic tool blocks and requires both sides of each exchange. Direct Gemini and Vertex accept an unmatched trailingfunctionCalland an out-of-orderfunctionResponse.Failure mode: a client sends a history whose last assistant turn contains a tool call that has no result yet, or whose duplicate-id exchange is intentional. On
ai-studioandvertex, that call part is now silently removed fromcontents. If the assistant turn contains only that call, Lines 73-75 of the repair helper drop the whole turn. The model then sees a different history than the client sent, with no error surfaced.

Reviewed exact head cd44ff9.\n\nThe earlier deterministic CCA wire blockers are fixed. A removed trailing Claude model prefill now forces the user continuation turn, unary CCA is explicitly SSE-only with the pinned flat-payload failure, raw SSE byte accounting is bounded across chunk splits, and duplicate tool-call ids are paired by occurrence. These contracts passed in the combined Antigravity focused run: 336 tests passed, 0 failed.\n\nThe remaining blockers are stack and integration state. This PR depends on #2068, is 66 commits behind current dev, GitHub reports CONFLICTING / DIRTY, and there is no exact-head Cross-platform CI or React Doctor run. Rebase and land #2068 first, restack this isolated CCA wire delta onto that current base, resolve the Google adapter conflicts without weakening the reviewed prefill/SSE/tool-pair rules, then rerun focused tests, typecheck, privacy scan, docs build, and exact-head CI.

Rechecked the restacked exact head f276d32535e2c35e2076d8ac13961ae8977a9f71 after your ping.
The stack shape is now correct and GitHub reports the PR mergeable: it is based on approved #2068 head 54c4f6a6eb8f, then carries the CCA wire slice. The range-diff preserves the already reviewed prefill, SSE byte-bound, duplicate-id, and unmatched-tool contracts. The non-equivalent part is the expected rebase reconciliation in f276d3253; I inspected that delta and it keeps Cloud Code Assist on the early SSE path while restoring Vertex-only non-stream replay/truncation handling and filtering tool results dropped by the repaired message list. I do not see a new conceptual blocker in that reconciliation.
My existing CHANGES_REQUESTED remains for integration state, not for a newly found CCA defect:
- #2068 still requires
@lidge-junexact-head security approval and merge first; - this stacked branch is still 37 commits behind current
dev@3e130d239and remains Draft; - it does not yet have authoritative exact-head Cross-platform CI / React Doctor on the final post-parent stack.
After #2068 lands, restack only this CCA slice onto the resulting current dev, preserve the reviewed contracts above, and request exact-head review again. There is no value in repeatedly rebasing this child while its security-sensitive parent is still open.
