ChangesGoogle Antigravity integration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The PR changes provider wire formatting and stream parsing. It is mergeable with owner awareness because one exact-cap stream test can pass without proving a terminal completion event, which could allow a regression in truncated-stream handling to go undetected; strengthening that assertion is recommended.

Inline comments:
In `@src/adapters/google.ts`:
- Around line 835-843: Update the cloud-code-assist branch of parseResponse to
call retainTranslatedEventBatch(events, budget) after collecting parseStream
events and before returning them, matching the normal finish() path. Add a
regression test covering a large unary CCA response with a constrained
translator budget.
- Around line 609-610: Enforce sseFrameMaxBytes per SSE frame rather than per
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.
In `@src/server/responses/core.ts`:
- 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.

- Around line 320-331: Update scanSseLineBytes to process LF bytes before
incrementing lineBytes, so the newline is excluded from the incomplete-line
maximum; preserve residual tracking for bytes after the newline. Add a
regression test covering an exact sseFrameMaxBytes data line followed by \n and
verify it is accepted.

Keep the CCA wire regression aligned with the upstream Claude prefill guard after restacking onto current dev.

adapter test to expect both the retained model turn and the appended user

collected events end with done. Preserve the existing replay/signature assertion
while ensuring the stream completes normally instead of ending without a
terminal signal.

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 |
