test: characterize pg-erd partial upstream response - #21
Conversation
📝 WalkthroughWalkthroughpg-erd에 HTTP 200 헤더 이후 부분 응답을 검증하는 통합 테스트가 추가되었습니다. 테스트는 응답 framing, readiness, 오류 메트릭, 독립 라우팅을 확인합니다. graceful-drain과 릴리스 증거 문서도 갱신되었습니다. Changes부분 응답 및 종료 계약
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This adds coverage for truncated committed responses, but the framing check can pass without a single valid Content-Length: 20 header. Tighten the assertion before merge so the test reliably protects the intended response behavior. Sequence Diagram(s)sequenceDiagram

Exact-head owner technical sweep for d4d4565854cc924a2214de2b67a966d2f253da3e...7b371cb341d42563eb112beab7dd421b7aa51b74: reviewed the complete six-path effective range. The partial-response fixture withholds origin close until the downstream has observed a complete committed HTTP/1.1 200 header and exact partial prefix, then requires termination before declared Content-Length: 20 completion; EOF/reset before that commit evidence fails the test. The request-error oracle is exact-line equality, /readyz and an independent frontend route remain acceptance gates, and the docs preserve the post-header no-second-response/no-failover boundary from pinned Pingora failure semantics without widening product retry authority. Fresh compare is behind=0 with merge base exactly the current #20 head and no stale parent source/workflow blob is in the effective range. No additional actionable source/documentation finding found. Current hosted CI/Supply Chain are still exact-head queued and are not credited by this review.

I verified the requested exact range. The parent is the merge base and an ancestor of the head. The effective diff changes exactly the six specified paths. The backend writes the complete HTTP/1.1 The downstream sends that acknowledgement only after it observes The test requires retained HTTP/1.1 The metric oracle uses exact-line equality: line == "cwl_pingora_gateway_request_errors_total 1"It cannot accept This is fresh source-level technical review evidence only. I did not run builds, tests, or hosted CI. It is not independent human approval. ✅ Action performedReview finished.

Exact-head owner technical sweep for d4d4565854cc924a2214de2b67a966d2f253da3e...51f1242663ccbf164efc50ca2ac74c4d0a1c7126: reviewed the complete six-path effective range after the CodeRabbit framing finding. The source now parses the original response header block by individual field lines, matches Content-Length case-insensitively, trims field-value whitespace, and requires the integration response to produce exactly one value 20. A focused regression separately proves X-Content-Length is ignored, mixed-case Content-Length is accepted, and duplicate/conflicting values remain observable as multiple values so the integration cardinality assertion rejects them. The existing downstream-commit handshake, exact single-error telemetry oracle, readiness/recovery gates, one-attempt/no-failover boundary, and product-authority separation remain unchanged. CHANGELOG.md, TEST_STRATEGY.md, TRD, TRACEABILITY and the product/technical gap baseline describe the same current behavior. Fresh compare is behind=0 with merge base exactly #20 and six effective paths. No additional actionable source/documentation finding found in this sweep. Hosted CI/Supply Chain for this exact head remain non-terminal and are not credited. This COMMENT is technical evidence only, not self-approval and not an independent human APPROVED review.

The focused regression covers lookalike names, mixed-case field identity, optional whitespace, and duplicate/conflicting fields. This is source-level technical review evidence only. I did not run builds, tests, or hosted CI. It is not independent human approval or merge authorization.

Buyer-visible migration gap
This child owns orderly post-header partial-response failure semantics for the characterized pg-erd migration profile. It does not add product auth, business routing, Wardnet/EgressWeave policy authority, or Keyverse identity behavior.
Current exact acceptance
The final exact head is
51f1242663ccbf164efc50ca2ac74c4d0a1c7126on exact parent #20d4d4565854cc924a2214de2b67a966d2f253da3e. Ordinary/non-force succession preserved only the valid partial-response child delta. The backend declaresContent-Length: 20, commits only the seven-bytepartialprefix, waits until that prefix has been observed downstream, and only then closes. Acceptance requires the committed 200/framing to remain visible without invented second status/failover,/readyz200, exactcwl_pingora_gateway_request_errors_total 1, and an independentfrontendrecovery request.The prior framing-oracle finding is repaired semantically: header lines are parsed,
