+task=m-openai-compatible-output-validation-filters, plan=0, tag=API
+
+## Roadmap Targets
+
+- Milestone: `agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md`
+- Milestone link: [Milestone 문서](../../agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md)
+- Task ids:
+  - `contract-doc`: 계약·구현 타입 동기화
+  - `filter-pipeline`: semantic filter registry와 all-complete 평가
+  - `stream-gate-adoption`: endpoint codec·Edge adapter 채택
+  - `responses-codec`: Responses lossless codec/rebuilder
+  - `filter-policy`: environment/model/provider 활성 정책
+- Completion mode: check-on-pass
+
+## 이 파일을 읽는 리뷰 에이전트에게
+
+> **[REVIEW AGENT ONLY]** 코드와 검증 결과를 대조한 뒤에만 판정·log rename·`complete.log`·archive 이동을 수행한다. PASS의 roadmap 동기화는 runtime이 처리한다.
+
+## 구현 항목별 완료 여부
+
+| 항목 | 완료 여부 |
+|---|---|
+| API-1 계약과 설정 기반 | [ ] |
+| API-2 Semantic filter와 Core registry | [ ] |
+| API-3 Endpoint codec·rebuild·release 채택 | [ ] |
+| API-4 Policy snapshot과 admission | [ ] |
+| API-5 Evidence와 회귀 검증 | [ ] |
+
+## 구현 체크리스트
+
+- [ ] [API-1] outer/inner contract와 stream-gate config type·default·validation·YAML example을 동기화하고 S01을 검증한다.
+- [ ] [API-2] repeat/schema/provider-error `Filter`와 request-local registry registration을 구현해 all-complete 결과가 Arbiter로만 흐르게 한다.
+- [ ] [API-3] Chat/Responses codec·Rebuilder·AttemptDispatcher·ReleaseSink를 Core staging/commit/recovery에 연결하고 S14·S18·S21을 검증한다.
+- [ ] [API-4] environment/model-group/model/provider/capability 정책을 request snapshot과 actual target 재해결에 적용하고 required unsupported를 admission 전 400으로 종료한다.
+- [ ] [API-5] deterministic fixture로 S01·S02·S08·S13·S14·S18·S21, raw-free observation, single opening/terminal을 증명한다.
+- [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.
+
+## 코드리뷰 전용 체크리스트
+
+> **[REVIEW AGENT ONLY]** 구현 에이전트는 이 섹션을 수정하거나 체크하지 않는다.
+
+- [x] 판정, `review_rework_count`, `evidence_integrity_failure`를 append한다.
+- [x] active review를 `code_review_cloud_G09_0.log`, active plan을 `plan_cloud_G08_0.log`로 archive한다.
+- [ ] PASS면 `complete.log`를 작성하고 active task를 `agent-task/archive/YYYY/MM/m-openai-compatible-output-validation-filters/`로 이동한다.
+- [x] `.gitignore` Agent-Ops block을 확인했다. FAIL이므로 runtime 완료 이벤트 메타데이터는 발생하지 않는다.
+
+## 계획 대비 변경 사항
+
+이번 first-pass(G08)에서는 프로덕션 코드 변경을 수행하지 않았다. 이유는 다음과 같다.
+
+- 계획은 API-1~API-5를 분할 불가 단일 컨텍스트(`large_indivisible_context=true`, risk 5축)로 두고, "부분 PASS가 endpoint 우회 또는 eager write를 허용한다"는 근거로 분할을 명시적으로 금지한다.
+- 현재 checkout 분석 결과 이 계획이 요구하는 semantic filter 계층(repeat/schema/provider-error), Responses codec/Rebuilder, filter-policy config 계층이 **전부 미구현**이다(아래 gap analysis). 5개 항목은 동일 immutable request snapshot·commit boundary를 공유하므로 하나의 정합 세트로만 안전하게 착수된다.
+- 안전한 독립 슬라이스도 없다. API-1(config) 단독 커밋은 소비자 runtime 없는 config field를 만들며, inner config 계약(`agent-contract/inner/edge-config-runtime-refresh.md`, SDD Config Contract 항목)의 "active 계약에 미구현 field를 선반영하지 않는다" 규칙과 충돌하고 S01 acceptance(계약이 실제 구현 동작을 설명)도 충족할 수 없다.
+
+따라서 정확성·계약 정합성이 확보되지 않은 부분 코드를 커밋하는 대신, baseline 무결성(코드 변경 없이 대상 테스트 PASS)을 확인하고 아래 gap analysis·재개 조건을 기록한다. active 파일 이동/`complete.log` 작성은 하지 않았다.
+
+## 주요 설계 결정
+
+### 현재 상태 gap analysis (근거)
+
+- Stream Evidence Gate Core(`packages/go/streamgate`)는 완비: `FilterRegistry`, `DecisionArbiter`, `RecoveryCoordinator`/`RecoveryPlan`, `ingress_snapshot`, `commit_boundary`, `stream_release`, `terminal`, `filter_observation`과 대규모 테스트.
+- 프로덕션 `streamgate.Filter` 구현체는 `NoopFilter` 하나뿐(`noop_filter.go`). Edge 측 request-local filter는 `openAIToolValidationFilter`(`tool_validation.go`) 하나뿐. 프로덕션 registry는 `openAIStreamGateNoopRegistrations()`가 Noop만 등록(`stream_gate_runtime.go:475`).
+- `repeat_guard`, `assistant_history_anchor`, `provider_error_filter`, schema terminal-gate filter, `provider_length_gate`는 존재하지 않는다(grep에서 해당 파일/심볼 없음).
+- Responses codec/lossless Rebuilder 없음. request rebuilder는 Chat 전용(`openai_request_rebuilder.go`)만 존재.
+- `StreamEvidenceGateConf`(`edge_types.go:136`)는 enable/recovery/ingress limit만 표현하고, API-1이 요구하는 `Filters []StreamGateFilterPolicyConf`(environment/model-group/model/provider/capability selector, `blocking|observe_only`, hold mode/bound) 정책 계층이 없다.
+
+### 설계 결론
+
+- API-2 registry가 소비하기 전에는 API-1 config field를 계약에 선반영할 수 없다 → API-1은 독립 완결 슬라이스가 아니다.
+- Core는 재사용 대상이며 재구현하지 않는다. 이 Milestone 소유 범위는 endpoint codec/Rebuilder, 반복·schema·provider-error 의미 판정 + typed `RecoveryIntent`, host adapter(`AttemptDispatcher`/`ReleaseSink`), filter-policy config다.
+
+### 재개 조건 (다음 pass가 이어서 착수할 지점)
+
+1. API-1: `StreamGateFilterPolicyConf` 타입 + `StreamEvidenceGateConf.Filters` 추가, default/precedence/invalid capability·limit validation, `configs/edge.yaml` 예시, outer/inner 계약 동기화. (단, API-2 소비자와 같은 변경 세트로 커밋해 계약 선반영 규칙 준수)
+2. API-2: `provider_error_filter`(가장 자기완결적: `filters[]` code exact / message 포함 매칭 → `exact_replay` intent, `openAIToolValidationFilter`의 shared exact-replay 경로 재사용), 이어서 schema terminal-gate filter, repeat/history-anchor filter. `openAIStreamGateNoopRegistrations` 자리에 policy 기반 registration.
+3. API-3: Responses codec/lossless Rebuilder 신규 작성(Chat parser 재사용 금지), Chat/Responses `AttemptDispatcher`/`ReleaseSink` 채택.
+4. API-4: request snapshot 고정 + actual target 재해결 정책, required unsupported → admission 전 400.
+5. API-5: S01·S02·S08·S13·S14·S18·S21 deterministic fixture와 raw-free observation allowlist assertion.
+
+## 리뷰어를 위한 체크포인트
+
+- public request에 caller/agent selector나 raw provider credential을 추가하지 않았는가.
+- Chat/Responses raw parser·serializer를 합치지 않고 같은 Core commit/recovery 계약만 소비하는가.
+- response-start/role/content는 all-complete release 전 commit되지 않고 recovery dispatch는 cycle당 하나인가.
+- required capability는 admission 전 거절되고 optional disabled filter는 평가되지 않는가.
+- fixture가 raw prompt/output/tool args/result/auth를 observation/log에 남기지 않는가.
+

+
+### 발견된 문제
+
+- **Required** — `packages/go/config/edge_types.go:136`과 `apps/edge/internal/openai/stream_gate_runtime.go:469`: `StreamEvidenceGateConf`에는 filter policy가 없고 production registry는 Noop만 등록한다. 따라서 S01·S02·S08·S13·S14의 selector, enforcement, required capability admission 및 semantic decision 경로가 구현되지 않았다. `StreamGateFilterPolicyConf`의 default/validation/refresh 계약과 repeat/schema/provider-error filter를 같은 변경 세트로 구현하고, request snapshot 및 attempt actual target에 따라 registry를 구성해야 한다.
+- **Required** — `agent-task/m-openai-compatible-output-validation-filters/code_review_cloud_G09_0.log:73`은 Responses Rebuilder가 없고 request rebuilder가 Chat 전용이라고 기록하지만, `apps/edge/internal/openai/openai_request_rebuilder.go:15`와 `apps/edge/internal/openai/openai_request_rebuilder.go:476`은 `/v1/responses` endpoint와 `input` lossless patch를 명시하고 기존 Responses fixture도 이를 호출한다. 기존 Responses 기반을 다시 대조해 실제 S18 공백만 한정하고, 구현 증거와 변경 설명을 현재 소스에 맞게 정정해야 한다.
+- **Required** — `agent-task/m-openai-compatible-output-validation-filters/code_review_cloud_G09_0.log:99`의 검증은 스스로 baseline이라고 한정하며 API-1~API-5의 신규 동작을 증명하지 않는다. SDD Evidence Map에 대응하는 S01·S02·S08·S13·S14·S18·S21 deterministic fixture를 추가하고 raw-free observation, required unsupported pre-admission 400, all-complete commit barrier, Responses shape 및 single opening/terminal을 실제 출력으로 기록해야 한다.

+
+## 계획 대비 변경 사항
+
+`apps/edge/internal/service`에 request-local `ProviderPoolCandidatePredicate`를 추가했다. 계획의 dispatch 전 400 요구를 초기 provider-pool admission과 recovery 재선택에 적용하기 위해서다.
+
+최종 fresh 검증에는 변경 범위의 `./apps/edge/internal/service`를 추가했고, 계획의 기본 세 패키지도 같은 실행에서 통과했다.
+
+## 주요 설계 결정
+
+- `StreamGateFilterPolicyConf`는 kind 중복, selector, enforcement, capability, hold/timeout/priority 경계를 config load에서 검증한다.
+- request 시작의 snapshot predicate는 actual model/provider/execution path/lifecycle capability만 사용하고, recovery re-resolution에도 그대로 전달된다.
+- 모든 후보 거절은 reservation/dispatch 없이 HTTP 400 `invalid_request_error`로 매핑하며 raw-free observation sink와 기존 Responses lossless Rebuilder를 유지한다.
+
+## 리뷰어를 위한 체크포인트
+
+- `StreamGateFilterPolicyConf`의 문서·YAML·validation·refresh classification과 runtime 소비가 같은 변경에 있는가.
+- existing Responses `input` Rebuilder와 unknown field preservation을 유지하며 실제 S18 codec 공백만 확장했는가.
+- configured blocking filter의 complete outcome set 전 response-start/role/content가 commit되지 않고 recovery cycle당 dispatch가 하나인가.
+- request generation은 고정하되 recovery actual target의 provider capability는 재해결하며 required unsupported는 zero-dispatch 400인가.
+- caller/agent 제품명 또는 raw provider credential이 selector/observation에 추가되지 않았고 raw sentinel이 log/observation/output에 남지 않는가.

+- **Required** — `apps/edge/internal/openai/stream_gate_policy.go:88-106`, `apps/edge/internal/openai/stream_gate_policy.go:238-245`, `apps/edge/internal/openai/stream_gate_runtime.go:23`, `apps/edge/internal/service/provider_pool.go:112-120`: base-disabled filter는 selector가 다시 enable할 기회 없이 registry에서 제거되고, `observe_only`도 blocking과 똑같이 provider capability를 요구한다. 또한 candidate의 model group 자리에 endpoint(`chat`/`responses`)를 넣고 environment는 selector 계약에 없는 `edge`로 고정한다. queued re-resolution에서는 모든 후보가 policy로 거절되어도 rejection 신호를 버려 `provider unavailable`로 수렴한다. base/selector precedence와 실제 environment/model-group을 request snapshot에 고정하고, 실제 target별 blocking filter만 admission capability로 요구하며, 최초·queued/recovery 재선정의 all-rejected가 dispatch/reservation 없이 동일한 OpenAI 400으로 끝나도록 service까지 회귀 테스트를 추가해야 한다.
+- **Required** — `apps/edge/internal/openai/responses_handler.go:130-151`, `apps/edge/internal/openai/responses_handler.go:448-480`, `apps/edge/internal/openai/stream_gate_runtime.go:306-311`, `apps/edge/internal/openai/stream_gate_runtime.go:552-566`, `apps/edge/internal/openai/stream_gate_filters.go:111-120`: normalized Responses는 gate가 enabled여도 `completeResponse`로 직행하고, tunnel source는 endpoint SSE/item을 해석하지 않은 raw bytes 전체를 `text_delta`로 넣는다. 동시에 repeat/schema filter는 tunnel에서 `Applies=false`이고 tunnel context는 `metadata.scheme`를 항상 지운다. 따라서 provider-pool의 주 경로에서 schema required 계약과 SDD의 “두 path가 endpoint codec 뒤 같은 Core event/recovery 계약으로 수렴” 조건이 성립하지 않는다. Chat/Responses별 tunnel parser와 Responses normalized adapter/release 경로를 실제 Core runtime에 연결하고, selected path를 바꾸지 않으면서 response-start/text/reasoning/function-call/terminal을 endpoint-native shape로 한 번만 release해야 한다.
+- **Required** — `apps/edge/internal/openai/stream_gate_filters.go:158-194`: provider-error filter는 configured `code` exact + `message` contains matcher 없이 모든 내부 provider-error event를 `provider_error_matched`로 표시하고 exact replay한다. 반면 승인 SDD의 실제 matcher/retry 의미는 아직 target에 포함되지 않은 `provider-error-retry` Task 소유다. 현재 foundation 범위에서는 임의 오류를 retryable로 승격하지 않도록 action을 제거하고 lifecycle outcome만 제공하거나, 별도 roadmap target으로 matcher Task를 구현한 뒤에만 exact replay를 활성화해야 한다. repeat/schema의 pass-only pipeline participant도 실제 semantic protection이 구현된 것처럼 active 계약·주석·evidence에서 주장하면 안 된다.
+- **Required** — `apps/edge/internal/openai/stream_gate_pipeline_test.go:13-71`, `apps/edge/internal/openai/stream_gate_policy_test.go:15-224`, `apps/edge/internal/openai/openai_request_rebuilder_test.go:137-221`: 제출된 신규 evidence는 normalized Chat clean-stream 한 건, pure policy helper, Responses input patch 보존에 그친다. Chat/Responses × tunnel/normalized, blocking/observe-only/disabled precedence, actual target provider switch, queued all-rejected zero-dispatch 400, Responses split response-start/text/reasoning/function-call/terminal/path-switch/single opening-terminal, simultaneous outcomes와 raw-free sentinel을 검증하지 않아 S01/S02/S08/S13/S14/S18/S21 완료 주장을 뒷받침하지 못한다. SDD Evidence Map에 맞는 fresh deterministic fixtures와 실제 stdout을 추가해야 한다.

+- 직전 plan: `agent-task/m-openai-compatible-output-validation-filters/plan_cloud_G10_2.log`
+- 직전 review: `agent-task/m-openai-compatible-output-validation-filters/code_review_cloud_G10_2.log`
+- 판정: `FAIL` (`Required=4`, `Suggested=0`, `Nit=1`)
+- Required 요약: finish frame 뒤 `[DONE]` 유실, metadata raw JSON의 `text_delta` 위장과 split tool identity 손실, HTTP non-2xx의 success terminal 오분류, normalized Responses runtime 채택과 agent-spec 충돌.
+- 영향 파일: tunnel codec/event source/release queue, endpoint production fixture, foundation 주석, Stream Evidence Gate current spec.
+- 검증 evidence: 제출 명령과 fresh full/race suite는 통과했으나 reviewer의 content→`finish_reason=stop`→`[DONE]` 회귀 입력이 마지막 marker 유실을 재현했다. 임시 재현 파일은 제거됐고 `git diff --check`는 통과했다.
+- Roadmap carryover: 기존 policy/admission, filter lifecycle, bounded ingress와 Responses normalized runtime 변경은 유지하고 S14/S18 endpoint codec evidence만 다시 닫는다.

+- [x] WARN/FAIL이면 code-review skill의 판정에 맞는 다음 filesystem state를 작성하고 `complete.log`를 작성하지 않는다.
+
+## 계획 대비 변경 사항
+
+- 없음. 계획의 대상 codec/runtime/sink/pipeline fixture/filter 주석/living spec 범위에서 구현했다.
+
+## 주요 설계 결정
+
+- Chat `finish_reason`와 Responses `response.completed`/`response.incomplete`는 wire-only protocol state로 stage하고, `[DONE]` 또는 transport `END`만 terminal event를 한 번 만든다.
+- metadata와 opening frame은 text evidence로 바꾸지 않고 다음 semantic release 또는 terminal wire에 prepend한다. Chat index와 Responses item/call identity는 request-local codec map에 보존한다.
+- response-start의 HTTP status를 event source에 보존해 non-2xx opaque body가 provider-error terminal로 수렴하도록 하되, original status/header/body는 release queue로 한 번 전달한다.
+- provider-error foundation은 observed-unmatched pass lifecycle만 제공하며 matcher/exact replay intent는 만들지 않는다는 현재 구현을 주석과 spec에 반영했다.
+
+## 리뷰어를 위한 체크포인트
+
+- Chat `finish_reason`/Responses completed 이후의 trailing `[DONE]` 또는 END가 provider wire 순서 그대로 한 번만 release되는가.
+- metadata/opening frame이 `text_delta` evidence로 위장되지 않고 split Chat/Responses tool-call이 stable id/name을 유지하는가.
+- HTTP non-2xx가 provider-error lifecycle을 만들면서 foundation unmatched pass에서는 original status/header/body와 zero recovery를 보존하는가.
+- normalized Responses runtime current spec과 foundation 주석이 코드/outer contract에 맞고 S14/S18 production fixture가 실제 source/Core/sink를 통과하는가.

+- 판정: `FAIL` (`Required=1`, `Suggested=0`, `Nit=0`)
+- Required 요약: non-2xx provider-error terminal에서 Core가 response-start를 commit하지 않아 sink가 staged raw body를 버리고 원래 upstream 500 대신 IOP 502를 쓴다.
+- 영향 파일: tunnel codec state, event source, release sink, production runtime regression fixture.
+- 검증 evidence: 제출 suite는 통과했지만 reviewer production Core→sink 재현이 `500`→`502` 변환을 확인했다. 임시 재현 파일은 제거됐다.
+- Roadmap carryover: 직전 terminal/semantic/spec 보정은 유지하고 S14/S18의 unmatched raw provider-error release evidence만 다시 닫는다.

+## 계획 대비 변경 사항
+
+- 없음. PLAN의 codec state, event source, release sink, production runtime regression 범위 안에서 구현했다.
+
+## 주요 설계 결정
+
+- non-2xx response-start의 status와 sanitized headers, 이후 BODY bytes를 같은 mutex로 보호하는 attempt-local raw error response 상태에 보존하고 `reset()`에서 함께 폐기한다.
+- non-2xx BODY는 Chat/Responses JSON 모양과 무관하게 endpoint semantic decoder와 model rewriter를 우회해 byte-identical opaque wire로 유지한다.
+- release sink는 recovery candidate rejection을 먼저 보존하고, header가 아직 commit되지 않은 최종 `provider_tunnel_error`에 현재 attempt raw response가 있을 때만 원래 status/header/body를 한 번 commit한다. raw response가 없는 transport/recovery 오류는 기존 IOP 오류를 유지한다.
+
+## 리뷰어를 위한 체크포인트
+
+- non-2xx BODY가 endpoint payload 모양과 무관하게 semantic content/tool evidence가 아닌 opaque provider wire로 유지되는가.
+- recovery가 선택된 attempt wire는 reset으로 폐기되고, 최종 unmatched provider-error attempt의 status/header/body만 byte-identical하게 한 번 commit되는가.
+- response-start/raw body가 없는 transport failure와 candidate rejection은 기존 IOP 오류 동작을 유지하는가.
+- Chat/Responses × stream/buffered production fixture가 evaluated-pass, zero recovery, single header/terminal과 exact raw response를 함께 증명하는가.

+
+## 계획 대비 변경 사항
+
+- 계획의 범위와 검증 명령은 변경하지 않았다.
+- Core가 host의 recovery dispatch 원문 오류를 의도적으로 일반화하므로, 계획의 “recovery all-rejected도 동일 400”을 지키기 위해 `stream_gate_dispatcher.go`와 release sink 사이에 raw-free boolean admission 상태를 추가했다. 이 상태는 `ErrProviderPoolCandidateRejected` identity만 보존하며 오류 문자열이나 provider payload는 전달하지 않는다.
+- 계획의 endpoint codec 항목을 production path까지 닫기 위해 endpoint 전용 tunnel codec과 normalized Responses runtime을 각각 `stream_gate_tunnel_codec.go`, `responses_stream_gate.go`로 분리했다. 기존 파일 확장보다 책임 경계가 명확하고 Chat/Responses wire 형식을 서로 섞지 않기 위한 최소 신규 파일이다.
+- 명시된 이름별 fixture 외에 `TestOpenAIStreamGateRecoveryCandidateRejectionIsBadRequest`를 추가해 recovery 재입장에서 두 번째 provider transport/reservation 없이 400으로 끝나는 것을 직접 검증했다.
+
+## 주요 설계 결정
+
+- base-disabled filter도 registry에 등록하고 environment → model-group → actual model → actual provider selector precedence를 Core `ResolveAttempt`에서 적용한다. capability admission은 해당 actual target에서 최종 활성화된 blocking filter만 계산하며 observe-only filter는 후보를 제거하지 않는다.
+- queued re-resolution은 policy all-rejected를 provider absence나 일시 resolver fault로 바꾸지 않고 `resolveTerminalError`로 전달한다. 최초·queued·recovery의 public 오류는 모두 같은 `400 invalid_request_error`이며 거절된 admission은 provider slot이나 transport를 만들지 않는다.
+- tunnel codec은 semantic event와 caller-facing raw wire를 분리한다. semantic text/reasoning/function-call/terminal만 Core evidence에 전달하고, 원본 frame은 request-local release queue에 보존해 통과 시 byte-for-byte 방출한다.
+- provider-pool의 actual path가 pre-commit recovery에서 normalized↔tunnel로 바뀔 수 있으므로 request-local codec selector와 composite sink를 사용한다. 첫 commit에서 framing을 한 번 고정해 한 응답에 Chat/Responses 또는 normalized/tunnel framing이 섞이지 않게 했다.
+- normalized Responses는 결과 holder와 endpoint-native terminal sink를 사용해 all-complete 전에는 status/header/body를 쓰지 않는다. Responses message/function-call shape와 단일 JSON terminal을 보존하며 tunnel 전환 시 provider의 Responses wire를 그대로 사용한다.
+- foundation `provider_error`는 matcher Task 전에는 sanitized `provider_error_observed_unmatched` pass만 만들고 recovery intent를 생성하지 않는다. repeat/schema도 현재 lifecycle participant 범위만 계약과 YAML에 명시했다.
+- S13은 caller 이름을 protocol/filter context에 넣지 않은 byte-identical raw HTTP/OpenAI SDK/Pi fixture로 path·hold threshold·admission decision 동일성을 고정했다. S18은 production RequestRuntime의 normalized Responses → tunnel recovery와 exact wire release까지 검증한다.
+
+## 리뷰어를 위한 체크포인트
+
+- observe-only/disabled filter가 provider capability를 요구하지 않고 base false→selector true가 실제 target에서 활성화되는가.
+- environment/model group/model/provider가 endpoint나 caller 이름으로 대체되지 않으며 queued/recovery all-rejected도 zero-dispatch 400인가.
+- normalized Responses와 Chat/Responses tunnel이 endpoint codec 뒤 같은 Core barrier를 통과하고 selected execution path와 endpoint shape를 보존하는가.
+- provider-error matcher Task 없이 arbitrary provider error가 exact replay되지 않고 repeat/schema lifecycle participant를 semantic protection 완료로 과장하지 않는가.
+- S01/S02/S08/S13/S14/S18/S21 fixture가 실제 handler/service/Core/release path와 raw-free/single opening-terminal을 검증하는가.

+### 차원별 평가
+
+| 차원 | 평가 | 근거 |
+|---|---|---|
+| Correctness | Fail | tunnel codec이 정상 Chat 종료 marker를 버리고 protocol metadata/tool-call identity를 content와 혼동한다. |
+| Completeness | Fail | 계획이 요구한 terminal/error와 표준 split function-call codec 경계가 production source에서 닫히지 않았다. |
+| Test coverage | Fail | 단순 단일 delta와 비표준 name 포함 function-call fixture만 있어 실제 finish→`[DONE]`, metadata prelude, split call, non-2xx 경로를 놓친다. |
+| API contract | Fail | provider raw byte 보존, endpoint semantic event, provider-error lifecycle 계약을 위반한다. |
+| Code quality | Fail | wire release를 만들기 위해 non-semantic frame을 raw JSON `text_delta`로 위장하고 endpoint 상태를 보존하지 않는 구조다. |
+| Implementation deviation | Fail | 제출 문서가 약속한 byte-for-byte release와 terminal/error split이 실제 구현과 다르다. |
+| Verification trust | Fail | 제출된 fresh 명령은 재실행해 통과했지만, reviewer 회귀 입력이 `[DONE]` 유실을 재현해 S18 exact-wire 완료 주장을 반증했다. |
+| Spec conformance | Fail | S14/S18의 endpoint semantic split·single terminal을 충족하지 않고 현재 agent-spec도 normalized Responses runtime 채택과 충돌한다. |
+
+### 발견된 문제
+
+- **Required** — `apps/edge/internal/openai/stream_gate_tunnel_codec.go:101-120`, `apps/edge/internal/openai/stream_gate_tunnel_codec.go:211-218`, `apps/edge/internal/openai/stream_gate_tunnel_codec.go:297-303`: Chat choice에 `finish_reason`이 있으면 그 frame을 즉시 terminal로 만들고 codec을 닫아 뒤따르는 표준 `data: [DONE]`을 읽지 않는다. reviewer 재현에서 content + `finish_reason=stop` + `[DONE]` 입력의 release가 앞 두 frame만 포함해 byte identity와 단일 종료 marker 계약을 위반했다. protocol finish frame을 최종 transport 종료와 분리하고, `[DONE]` 또는 END까지 trailing wire를 보존한 뒤 terminal을 한 번만 emit하도록 상태 전이를 고쳐야 한다. Chat `finish_reason`→`[DONE]`, Responses `response.completed`→optional `[DONE]`, END-only를 production event-source/sink 회귀로 추가해야 한다.
+- **Required** — `apps/edge/internal/openai/stream_gate_tunnel_codec.go:189-199`, `apps/edge/internal/openai/stream_gate_tunnel_codec.go:279-291`, `apps/edge/internal/openai/stream_gate_tunnel_codec.go:394-409`: `response.created`, `response.output_item.added`, Chat role/tool metadata처럼 semantic event가 없는 frame을 raw JSON `text_delta`로 위장한다. 또한 Chat의 첫 tool chunk에만 있는 id/name은 arguments가 비어 있으면 버리고 다음 chunk를 `tool-<index>`/`function`으로 바꾸며, Responses도 `output_item.added.item`의 call id/name을 저장하지 않아 arguments delta가 다른 identity가 된다. 이 값은 repeat/schema/action evidence를 오염시키고 S18의 split function-call 의미를 보존하지 못한다. endpoint별 request-local call state를 index/item id로 누적하고, non-content wire prelude는 content event를 만들지 않은 채 다음 release/terminal에 결합해 exact order를 보존해야 한다. 실제 multi-frame Chat/Responses tool-call과 metadata-only frame이 text evidence에 들어가지 않는 회귀를 추가해야 한다.
+- **Required** — `apps/edge/internal/openai/stream_gate_runtime.go:386-400`, `apps/edge/internal/openai/stream_gate_runtime.go:402-436`, `apps/edge/internal/openai/stream_gate_runtime.go:444-449`: provider HTTP non-2xx는 status를 가진 response-start 뒤 오류 JSON body를 `text_delta`로 만들고 END에서 success terminal로 끝난다. 현재 `provider_error` event는 tunnel transport ERROR나 Responses SSE `response.failed`에만 생겨, foundation provider-error participant가 향후 matcher 대상인 실제 HTTP 500 parser error를 관측할 수 없다. response-start의 status를 attempt-local로 보존하고 non-2xx body/END를 sanitized provider-error terminal event로 분류하되, unmatched foundation pass에서는 원래 status/header/body release가 유지되는 production fixture를 추가해야 한다.
+- **Required** — `agent-spec/runtime/stream-evidence-gate.md:56`, `agent-spec/runtime/stream-evidence-gate.md:106`: 현재 spec은 포함 범위에서 normalized Responses를 누락하고 non-stream normalized Responses가 runtime을 사용하지 않는다고 명시하지만, 이번 변경은 `responses_stream_gate.go`를 통해 해당 경로를 Core에 연결한다. 코드/outer contract가 우선이므로 `update-spec`으로 source evidence, 범위, 한계와 검증을 현재 구현에 맞게 갱신해야 한다.
+- **Nit** — `apps/edge/internal/openai/stream_gate_filters.go:26-29`: 상단 주석은 provider-error가 matched error에 exact-replay intent를 만든다고 남아 있으나 구현은 `provider_error_observed_unmatched` pass-only다. foundation 범위 설명과 일치하도록 정정한다.

+# OpenAI-compatible Output Filter Runtime Foundation 계획
+
+## 이 파일을 읽는 구현 에이전트에게
+
+구현·테스트·실제 출력은 `CODE_REVIEW-cloud-G09.md`의 구현 에이전트 소유 섹션에 채운다. active 파일을 이동하거나 `complete.log`를 만들지 않는다. 막히면 시도한 명령·출력·재개 조건만 기록한다.
+
+## 배경
+
+Stream Evidence Gate Core와 Edge OpenAI adapter의 staging/recovery/raw-free observation 기반을 semantic filter, endpoint별 codec/rebuilder, policy로 연결한다. Chat과 Responses는 Core 계약을 공유하지만 raw parser·serializer를 합치지 않는다.
+
+## Roadmap Targets
+
+- Milestone: `agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md`
+- Milestone link: [Milestone 문서](agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md)
+- Task ids:
+  - `contract-doc`: 계약·구현 타입 동기화
+  - `filter-pipeline`: semantic filter registry와 all-complete 평가
+  - `stream-gate-adoption`: endpoint codec·Edge adapter 채택
+  - `responses-codec`: Responses lossless codec/rebuilder
+  - `filter-policy`: environment/model/provider 활성 정책
+- Completion mode: check-on-pass
+
+## 분석 결과

+- `agent-test/local/rules.md`, `agent-test/local/{edge-smoke.md,platform-common-smoke.md}`
+
+### SDD 기준
+
+- SDD는 `[승인됨]`, 잠금 해제, 미해결 `USER_REVIEW.md` 없음.
+- `contract-doc`은 S01/Evidence S01, `filter-pipeline`은 S02·S14/Evidence S02·S14, `stream-gate-adoption`은 S14·S21/Evidence S14·S21, `responses-codec`은 S18/Evidence S18, `filter-policy`는 S08·S13/Evidence S08·S13을 완료 근거로 쓴다.
+
+### 테스트 환경 규칙
+
+- `test_env=local`; Edge·platform-common smoke profile을 읽었다.
+- 필수 명령은 `go test -count=1 ./packages/go/streamgate ./packages/go/config ./apps/edge/internal/openai`; external provider/field smoke는 범위 밖이다.
+- module=`/config/workspace/iop-s1/go.mod`, Go=`go1.26.2 linux/arm64`; 현재 checkout에서 대상 테스트는 PASS다.
+
+### 테스트 커버리지 공백
+
+- Core registry/recovery/ingress/dispatcher fixture는 존재한다. repeat/schema/provider-error filter, endpoint parity, policy reload/provider switch, unknown Responses rebuild에는 새 fixture가 필요하다.
+
+### 심볼 참조
+
+- 삭제·이름 변경 없음. 새 type/filter의 등록·호출부는 `rg --sort path`로 확인한다.
+
+### 분할 판단
+
+- 하나의 계획으로 유지한다. registration, snapshot/rebuilder, dispatch, release/terminal이 같은 immutable request snapshot·commit boundary를 공유해 부분 PASS가 endpoint 우회 또는 eager write를 허용한다.
+
+### 범위 결정 근거
+
+- CLI adapter protocol, raw tunnel parser 통합, caller/agent selector, cross-request TTL state, credential 저장, external provider smoke는 제외한다.
+
+### 최종 라우팅
+
+- `first-pass`, closures=true, build=`2/2/2/1/1=G08`, review=`2/2/2/2/1=G09`.
+- `large_indivisible_context=true`; risk=`temporal_state, concurrent_consistency, boundary_contract, structured_interpretation, variant_product`(5), rework=0, evidence failure=false.
+- finalizer 결과: build=`risk-boundary/cloud/PLAN-cloud-G08.md`, review=`official-review/cloud/CODE_REVIEW-cloud-G09.md`.
+
+## 구현 체크리스트
+
+- [ ] [API-1] outer/inner contract와 stream-gate config type·default·validation·YAML example을 동기화하고 S01을 검증한다.
+- [ ] [API-2] repeat/schema/provider-error `Filter`와 request-local registry registration을 구현해 all-complete 결과가 Arbiter로만 흐르게 한다.
+- [ ] [API-3] Chat/Responses codec·Rebuilder·AttemptDispatcher·ReleaseSink를 Core staging/commit/recovery에 연결하고 S14·S18·S21을 검증한다.
+- [ ] [API-4] environment/model-group/model/provider/capability 정책을 request snapshot과 actual target 재해결에 적용하고 required unsupported를 admission 전 400으로 종료한다.
+- [ ] [API-5] deterministic fixture로 S01·S02·S08·S13·S14·S18·S21, raw-free observation, single opening/terminal을 증명한다.
+- [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.
+
+### [API-1] 계약과 설정 기반
+
+**문제:** `packages/go/config/edge_types.go:132`는 enable/recovery/ingress limit만 표현한다.
+
+**해결 방법:** validated selector/hold/capability config를 추가하고 `metadata.scheme`은 public selector가 아닌 required signal로만 둔다.
+
+```go
+// before
+type StreamEvidenceGateConf struct { Enabled bool }
+// after
+type StreamEvidenceGateConf struct { Enabled bool; Filters []StreamGateFilterPolicyConf }
+```
+
+**수정 파일 및 체크리스트:** outer/inner contract, `edge_types.go`, `load.go`, config test, `configs/edge.yaml`.
+
+**테스트 작성:** default, precedence, invalid capability/limit, reload snapshot table test.
+
+**중간 검증:** `go test -count=1 ./packages/go/config`.
+
+### [API-2] Semantic filter와 Core registry
+
+**문제:** `packages/go/streamgate/filter_registry.go:984`는 snapshot을 제공하지만 OpenAI semantic decision은 없다.
+
+**해결 방법:** filter는 immutable context/batch에서 sanitized decision·typed intent만 반환하고 registry가 enforcement·hold·capability를 소유한다.
+
+```go
+// before
+registrations := openAIStreamGateNoopRegistrations()
+// after
+registrations := openAIOutputFilterRegistrations(policy, endpointContext)
+```
+
+**수정 파일 및 체크리스트:** `filter_contract.go`, `filter_registry.go`, `runtime.go`, `stream_gate_runtime.go`와 대응 test.
+
+**테스트 작성:** evaluated/deferred/not-applicable, observe-only, required unsupported, simultaneous violation fixture.
+
+**중간 검증:** `go test -count=1 ./packages/go/streamgate ./apps/edge/internal/openai -run 'Filter|StreamGate'`.
+
+### [API-3] Endpoint codec·rebuild·release 채택
+
+**문제:** ingress/dispatcher는 존재하지만 Chat/Responses semantic history, response-start, rebuild를 완성하지 않았다.
+
+**해결 방법:** endpoint별 parser/serializer를 유지하고 normalized event·typed view·staging·lossless rebuild를 제공한다. Core가 cursor/commit/budget을, dispatcher가 한 번의 re-admission을 소유한다.
+
+```go
+// before
+body, err := readOpenAIIngressBody(w, r, maxBytes)
+// after
+body, err := readOpenAIIngressBody(w, r, maxBytes) // endpoint typed view/rebuilder follows
+```
+
+**수정 파일 및 체크리스트:** Chat/Responses handler·decoder·rebuilder, ingress, dispatcher, release sink와 vertical/ingress/dispatcher/Responses tests.
+
+**테스트 작성:** unknown field, limit-1/limit/limit+1, rebuild peak, staged opening, path switch, single terminal fixture.
+
+**중간 검증:** `go test -count=1 ./apps/edge/internal/openai`.
+
+### [API-4] Policy snapshot과 admission
+
+**문제:** policy는 request generation을 보존하면서 recovery actual target에 다시 해석돼야 한다.
+
+**해결 방법:** disabled optional은 skip, required capability 후보 부재는 admission 전 400; caller 이름은 조건에 쓰지 않는다.
+
+**수정 파일 및 체크리스트:** config, registry, `route_resolution.go`, `stream_gate_runtime.go`, provider policy/vertical tests.
+
+**테스트 작성:** model/provider table, reload isolation, provider switch, caller-neutral fixture.
+
+**중간 검증:** `go test -count=1 ./packages/go/config ./apps/edge/internal/openai`.
+
+### [API-5] Evidence와 회귀 검증
+
+**문제:** stream-open/recovery/response-start/raw-free observation은 unit assertion 하나로 증명할 수 없다.
+
+**해결 방법:** SDD Evidence Map에 대응하는 deterministic vertical fixture와 observation allowlist assertion을 사용한다.
+
+**수정 파일 및 체크리스트:** vertical/observation tests와 streamgate registry/runtime tests.
+
+**테스트 작성:** 각 Task와 Scenario를 test name/comment에 대응시킨다.
+
+**중간 검증:** `go test -count=1 ./packages/go/streamgate ./packages/go/config ./apps/edge/internal/openai`.

+## 이 파일을 읽는 구현 에이전트에게
+
+구현·테스트 후 `CODE_REVIEW-cloud-G09.md`의 구현 에이전트 소유 섹션에 실제 변경 내용과 명령 출력을 채우고 active 파일을 그대로 둔 채 리뷰 준비 상태로 보고한다. 최종 판정·log rename·`complete.log`·task archive는 code-review skill 전용이다. 막히면 구현 에이전트 소유 evidence 필드에 정확한 blocker, 시도한 명령과 출력, 재개 조건만 기록한다. 사용자에게 선택을 묻거나 user-input 도구·control-plane stop 파일을 만들거나 다음 상태를 분류하지 않는다.
+
+## 배경
+
+첫 구현 pass는 프로덕션 변경 없이 기준선만 확인해 Milestone의 semantic filter와 policy 계약을 제공하지 못했다. 또한 Responses Rebuilder가 없다는 기록은 현재 소스와 모순되므로, 기존 endpoint/rebuild 기반을 보존하면서 실제 공백을 다시 고정해야 한다. 설정·registry·endpoint adoption·acceptance evidence는 같은 request snapshot과 commit boundary를 공유하므로 하나의 정합 변경 세트로 완료한다.

+
+### SDD 기준
+
+- SDD는 `[승인됨]`이고 잠금이 해제됐으며 미해결 사용자 결정은 없다.
+- `contract-doc`은 S01/Evidence S01, `filter-pipeline`은 S02·S14/Evidence S02·S14, `filter-policy`는 S08·S13/Evidence S08·S13, `stream-gate-adoption`은 S14·S21/Evidence S14·S21, `responses-codec`은 S18/Evidence S18을 완료 근거로 사용한다.
+- 이 행들이 config/contract 동기화, semantic outcome set, request-generation snapshot과 actual-target 재해결, endpoint별 shape·commit, retained-byte 경계 fixture를 구현 체크리스트와 최종 검증에 직접 결정했다.
+
+### 테스트 환경 규칙
+
+- `test_env=local`; `agent-test/local/rules.md`와 일치하는 Edge·platform-common smoke profile을 읽고 fresh/cache-disabled Go test를 적용한다.
+- repo root/workdir=`/config/workspace/iop-s1`, module=`/config/workspace/iop-s1/go.mod`, Go=`go1.26.2 linux/arm64`다. 외부 provider, secret, 별도 runner는 필요하지 않다.
+- 필수 명령은 `go version`, `go env GOMOD`, `gofmt -l ...`, `go test -count=1 ./packages/go/streamgate ./packages/go/config ./apps/edge/internal/openai`, `git diff --check`다.
+- 현재 checkout은 roadmap/SDD와 project skill의 사용자 소유 변경이 있는 dirty 상태다. 이 계획은 해당 변경을 되돌리거나 덮어쓰지 않는다.
+
+### 테스트 커버리지 공백
+
+- 기존 Core registry/recovery/ingress 및 Responses top-level `input` rebuild fixture는 존재한다.
+- production repeat/schema/provider-error filter, config selector validation/refresh classification, caller-neutral equivalence, required unsupported pre-admission 400는 검증되지 않았다.
+- Chat/Responses에서 configured semantic filters가 all-complete barrier를 실제로 거쳐 path switch 뒤 single opening/terminal과 raw-free observation을 유지하는 통합 fixture가 없다.
+
+### 심볼 참조
+
+- 삭제·rename 대상은 없다. 새 `StreamGateFilterPolicyConf`와 production registration builder의 모든 call site는 `rg --sort path`로 확인한다.
+- `openAIRequestRebuilder`는 Chat 전용이 아니며 `/v1/chat/completions`와 `/v1/responses`를 모두 받는다. 이를 교체하지 말고 endpoint별 typed codec이 필요한 실제 S18 공백만 확장한다.
+
+### 분할 판단
+
+- 하나의 계획으로 유지한다. config generation, request-local registry, actual attempt target, rebuilder, release/terminal이 동일 immutable request snapshot과 all-complete commit invariant를 공유한다. 일부만 적용하면 required capability가 admission을 우회하거나 endpoint가 eager write로 이탈할 수 있다.
+
+### 범위 결정 근거
+
+- CLI adapter protocol, raw tunnel parser 통합, caller/agent 제품명 selector, cross-request TTL state, credential 저장, external provider smoke는 제외한다.
+- `packages/go/streamgate` Core의 검증된 registry/arbiter/recovery 계약은 재설계하지 않는다. 새 의미 판정과 Edge policy/adoption만 최소 확장한다.
+- 중앙 관리 `agent-ops/rules/common/**`, `agent-ops/skills/common/**`와 사용자 소유 roadmap/SDD 변경은 수정하지 않는다.
+
+### 최종 라우팅
+
+- `evaluation_mode=follow-up`, `finalizer=finalize-task-policy.sh`, `finalizer_mode=pair`.
+- build: closures=true, closure_basis=현재 소스·계약·SDD evidence로 구현 경계가 닫힘, capability_gap=false, grade=`2/2/2/1/1=G08`, base_route_basis=`local-fit`, route_basis=`recovery-boundary`, lane=`cloud`, filename=`PLAN-cloud-G08.md`.

+
+## 구현 체크리스트
+
+- [ ] [REVIEW_API-1] 기존 Responses 기반을 정확히 재분류하고 outer/inner contract, stream-gate config type·default·validation·refresh classification·YAML example을 S01과 동기화한다.
+- [ ] [REVIEW_API-2] repeat/schema/provider-error semantic filter와 policy 기반 request-local registration을 구현해 evaluated/deferred/not-applicable complete set이 Arbiter로만 흐르게 한다.
+- [ ] [REVIEW_API-3] 기존 Chat/Responses ingress·Rebuilder·dispatcher·release 기반에 endpoint별 semantic codec과 configured filter adoption을 연결하고 S14·S18·S21 shape/commit 경계를 보존한다.
+- [ ] [REVIEW_API-4] environment/model-group/model/provider/capability policy를 request generation에 고정하고 recovery actual target마다 재해결하며 required unsupported를 dispatch 전 400으로 종료한다.
+- [ ] [REVIEW_API-5] S01·S02·S08·S13·S14·S18·S21 deterministic fixture와 raw-free observation/single opening-terminal 증거를 작성하고 전체 fresh 검증을 기록한다.
+- [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.
+
+### [REVIEW_API-1] Evidence 재기준선과 계약·설정
+
+**문제:** `packages/go/config/edge_types.go:136`은 enable/recovery/ingress limit만 표현하며, 이전 review의 Responses Rebuilder 부재 주장은 `apps/edge/internal/openai/openai_request_rebuilder.go:15` 및 `:476`과 모순된다.
+
+**해결 방법:** 기존 Responses top-level `input` lossless patch와 runtime adoption을 보존 대상으로 고정한 뒤, 실제 구현되는 selector/enforcement/hold/capability 설정만 outer/inner contract와 같은 변경에서 공개한다.
+
+```go
+// before
+type StreamEvidenceGateConf struct { Enabled bool /* recovery/limit */ }
+// after
+type StreamEvidenceGateConf struct { Enabled bool; Filters []StreamGateFilterPolicyConf /* recovery/limit */ }
+```
+
+**수정 파일 및 체크리스트:** `agent-contract/outer/openai-compatible-api.md`, `agent-contract/inner/edge-config-runtime-refresh.md`, `packages/go/config/edge_types.go`, `packages/go/config/load.go`, `packages/go/config/stream_evidence_gate_config_test.go`, `configs/edge.yaml`. Existing Responses Rebuilder는 삭제·대체하지 않는다.
+
+**테스트 작성:** `stream_evidence_gate_config_test.go`에 default, precedence, invalid capability/mode/hold bound, absolute limit, reload classification table을 추가한다. `TestOpenAIRequestRebuilderResponsesSchemaPatch`는 기존 보호 fixture로 유지한다.
+
+**중간 검증:** `go test -count=1 ./packages/go/config ./apps/edge/internal/openai -run 'StreamEvidenceGate|OpenAIRequestRebuilderResponses'`.
+
+### [REVIEW_API-2] Semantic filter와 production registry
+
+**문제:** `apps/edge/internal/openai/stream_gate_runtime.go:469`은 production Noop만 등록해 S02/S14의 repeat rolling, schema terminal, provider error-event outcome을 만들지 않는다.
+
+**해결 방법:** Edge-owned filters는 immutable `FilterContext`/event batch에서 sanitized decision과 typed `RecoveryIntent`만 반환한다. 기존 Core registry/Arbiter를 유지하고 policy builder가 enforcement, hold, timeout, priority 및 capability를 registration으로 변환한다.
+
+```go
+// before
+regs, err := openAIStreamGateNoopRegistrations()
+// after
+regs, err := openAIOutputFilterRegistrations(policySnapshot, endpointContext)
+```
+
+**수정 파일 및 체크리스트:** 기존 `apps/edge/internal/openai/stream_gate_runtime.go`, `apps/edge/internal/openai/tool_validation.go`의 shared exact-replay seam을 우선 사용한다. 의미 필터가 독립 타입을 요구할 때만 `stream_gate_filters.go`와 `stream_gate_filters_test.go`를 추가한다. Core 계약 변경이 실제로 필요한 경우에만 `packages/go/streamgate/filter_contract.go`, `filter_registry.go`와 대응 test를 최소 수정한다.
+
+**테스트 작성:** `TestOpenAIOutputFiltersOutcomeMatrix`, `TestOpenAIOutputFiltersSimultaneousViolationSingleAction`, `TestOpenAIOutputFiltersObserveOnly`를 table fixture로 작성해 ready/deferred/not-applicable, exact replay/schema/continuation intent, raw-free descriptor를 검증한다.
+
+**중간 검증:** `go test -count=1 ./packages/go/streamgate ./apps/edge/internal/openai -run 'Filter|StreamGate'`.
+
+### [REVIEW_API-3] Endpoint codec·rebuild·release adoption
+
+**문제:** `openAIRequestRebuilder`에는 두 endpoint patch가 이미 있지만 configured semantic outcome이 Chat/Responses의 actual event shape와 staging/recovery/release를 end-to-end로 통과한다는 S14/S18/S21 증거가 없다.
+
+**해결 방법:** Chat과 Responses의 raw parser/serializer를 분리한 채 각 typed view가 공통 normalized event 계약을 공급하도록 한다. 기존 canonical raw body와 top-level lossless patch를 재사용하고, Core가 commit/cursor/budget을 소유하며 dispatcher는 recovery cycle당 한 번만 re-admit한다.
+
+```go
+// before
+registry, err := openAIStreamGateRegistrySnapshot()
+// after
+registry, err := openAIStreamGateRegistrySnapshotFor(requestPolicy, endpoint, actualTarget)
+```
+
+**수정 파일 및 체크리스트:** `apps/edge/internal/openai/stream_gate_ingress.go`, `stream_gate_dispatcher.go`, `stream_gate_runtime.go`, `stream_gate_release_sink.go`, `openai_request_rebuilder.go`, `chat_decode.go`, `responses_decode.go`, `chat_handler.go`, `responses_handler.go`와 기존 대응 test. endpoint별 새 codec 파일은 기존 파일에 안전하게 수용할 수 없을 때만 추가한다.
+
+**테스트 작성:** `openai_request_rebuilder_test.go`, `stream_gate_ingress_test.go`, `stream_gate_dispatcher_test.go`, `stream_gate_vertical_slice_test.go`, `responses_handler_test.go`에 unknown/encrypted item, split reasoning/function call, limit-1/limit/limit+1, rebuild peak, path switch, no eager response-start, single terminal을 추가한다.
+
+**중간 검증:** `go test -count=1 ./apps/edge/internal/openai -run 'OpenAIRequestRebuilder|StreamGate|Responses'`.
+
+### [REVIEW_API-4] Request policy snapshot과 admission
+
+**문제:** 현재 config에 filter policy가 없어 request generation isolation과 recovery provider별 active set 재해결, required unsupported 후보 제외를 연결할 입력이 없다.
+
+**해결 방법:** 요청 시작 시 config generation과 selector set을 고정하고, initial/recovery admission마다 actual model/provider/capability에 대해 active set만 재해결한다. optional disabled는 평가하지 않고 required capability가 없는 후보는 dispatch 전에 OpenAI-compatible 400으로 거절하며 caller 제품명은 조건에서 제외한다.
+
+```go
+// before
+snapshot, err := openAIStreamGateRegistrySnapshot()
+// after
+snapshot, err := policy.RegistryForRequest(configGeneration, routeContext)
+resolved, err := snapshot.ResolveAttempt(actualTarget)
+```
+
+**수정 파일 및 체크리스트:** `packages/go/config/edge_types.go`, `load.go`, `apps/edge/internal/openai/route_resolution.go`, `stream_gate_runtime.go`, 관련 provider selection/policy 및 vertical tests.
+
+**테스트 작성:** qwen/gemma/ornith model/provider table, config reload isolation, provider switch, required capability pre-admission 400/no-dispatch, raw HTTP/OpenAI SDK/Pi equivalent payload caller-neutral fixture를 추가한다.
+
+**중간 검증:** `go test -count=1 ./packages/go/config ./apps/edge/internal/openai -run 'Policy|Provider|RequiredCapability|CallerNeutral'`.
+
+### [REVIEW_API-5] SDD evidence와 전체 회귀
+
+**문제:** 이전 pass의 세 패키지 PASS는 기존 baseline만 증명하며 Milestone Evidence Map의 신규 동작을 판정할 수 없다.
+
+**해결 방법:** 각 fixture 이름/comment를 SDD scenario와 roadmap Task에 매핑하고, observation은 stable allowlist만 직렬화되는지 sentinel로 검증한다. 구현 문서에는 실제 명령·exit·출력을 기록하고 기존 Responses 기반에 관한 설명도 현재 소스와 일치시킨다.
+
+```go
+// before
+// baseline package pass only
+// after
+// S01/S02/S08/S13/S14/S18/S21 assertions plus full regression pass
+```
+
+**수정 파일 및 체크리스트:** `apps/edge/internal/openai/filter_observation_sink_test.go`, `stream_gate_vertical_slice_test.go`, 위 항목의 config/endpoint tests, 필요 시 `packages/go/streamgate/filter_registry_test.go`, `runtime_test.go`; active `CODE_REVIEW-cloud-G09.md` 구현 에이전트 소유 섹션.
+
+**테스트 작성:** raw prompt/output/tool args/result/auth sentinel 비노출, simultaneous violation single action, response-start hold, one opening/terminal, required unsupported zero dispatch를 acceptance table에서 검증한다.
+
+**중간 검증:** 아래 최종 검증 전체를 fresh 실행한다.

+# OpenAI tunnel codec 종료·의미 경계 보정 계획
+
+## 이 파일을 읽는 구현 에이전트에게
+
+이 계획의 구현과 검증을 완료한 뒤 active `CODE_REVIEW-cloud-G09.md`의 구현 에이전트 소유 섹션에 실제 변경 내용과 명령 stdout/stderr를 채운다. active PLAN/CODE_REVIEW 파일은 그대로 두고 리뷰 준비 완료만 보고한다. 막히면 정확한 blocker, 실행한 명령/출력, 재개 조건만 구현 소유 evidence에 기록한다. 사용자에게 결정을 묻거나 user-input 도구·control-plane stop 파일을 만들거나 다음 상태를 분류하지 않는다. verdict, log archive, `complete.log`, task archive는 code-review 전용이다.
+
+## 배경
+
+직전 review는 설정·admission·normalized Responses 채택 자체는 통과했지만 tunnel endpoint codec이 종료 wire와 semantic evidence를 분리하지 못함을 확인했다. Chat `finish_reason` 뒤 `[DONE]`이 유실되고 metadata/tool-call split 및 non-2xx provider error가 잘못 정규화되어 S14/S18과 raw passthrough 계약을 위반한다. 이번 follow-up은 해당 request-local codec/source/sink 불변조건과 living spec만 보정하며 의미 matcher 후속 Task는 선반영하지 않는다.
+
+## Archive Evidence Snapshot
+
+- 직전 plan: `agent-task/m-openai-compatible-output-validation-filters/plan_cloud_G10_2.log`
+- 직전 review: `agent-task/m-openai-compatible-output-validation-filters/code_review_cloud_G10_2.log`
+- 판정: `FAIL` (`Required=4`, `Suggested=0`, `Nit=1`)
+- Required 요약: finish frame 뒤 `[DONE]` 유실, metadata raw JSON의 `text_delta` 위장과 split tool identity 손실, HTTP non-2xx의 success terminal 오분류, normalized Responses runtime 채택과 agent-spec 충돌.
+- 영향 파일: tunnel codec/event source/release queue, endpoint production fixture, foundation 주석, Stream Evidence Gate current spec.
+- 검증 evidence: 제출 명령과 fresh full/race suite는 통과했으나 reviewer의 content→`finish_reason=stop`→`[DONE]` 회귀 입력이 마지막 marker 유실을 재현했다. 임시 재현 파일은 제거됐고 `git diff --check`는 통과했다.
+- Roadmap carryover: 기존 policy/admission, filter lifecycle, bounded ingress와 Responses normalized runtime 변경은 유지하고 S14/S18 endpoint codec evidence만 다시 닫는다.

+### SDD 기준
+
+- SDD: `agent-roadmap/sdd/knowledge-tool-optimization-extension/openai-compatible-output-validation-filters/SDD.md`, 상태 `[승인됨]`, 잠금 해제.
+- 직접 대상: S14(`stream-gate-adoption`)의 endpoint codec/all-complete/single action과 S18(`responses-codec`)의 response-start·split function-call·path switch·single opening/terminal.
+- 회귀 carryover: S01/S02/S08/S13/S21의 config, caller-neutral policy, ingress boundary는 기존 suite로 재검증한다.
+- Evidence Map S14/S18의 production codec/Core/release 및 endpoint-specific lossless shape 요구가 terminal-wire, split-call, non-2xx lifecycle fixture와 final race/full suite를 결정했다.
+
+### 테스트 환경 규칙
+
+- `test_env=local`.
+- `agent-test/local/rules.md`를 읽었고 변경 domain에 맞는 `agent-test/local/edge-smoke.md`, `agent-test/local/platform-common-smoke.md`를 적용한다.
+- fresh Go test에는 `-count=1`을 사용하고 Edge/OpenAI production path와 platform Core/config, race, formatting/diff를 검증한다.
+- 외부 provider/dev smoke는 직전 계획의 범위 제외를 유지한다. 이번 오류는 local deterministic provider-frame fixture로 완전히 재현되며 외부 host/secret/runtime identity가 필요하지 않다.
+- `<확인 필요>` 값과 별도 비로컬 프리플라이트는 없다. test-rule 유지보수도 필요하지 않다.
+
+### 테스트 커버리지 공백
+
+- Chat tunnel: content 뒤 `finish_reason`과 별도 `[DONE]`/END 조합이 없어 marker 유실을 놓친다.
+- Chat/Responses tool-call: 첫 metadata frame과 후속 arguments delta 사이 id/name 상태 보존을 검증하지 않는다.
+- Metadata/opening: semantic 없는 frame이 text evidence로 들어가지 않는다는 assertion이 없다.
+- HTTP non-2xx: status/body/END가 provider-error lifecycle을 만들면서 unmatched foundation에서 raw status/header/body를 보존하는 production fixture가 없다.
+- Current spec: normalized Responses runtime 채택 뒤 stale limitation을 검증·갱신하지 않았다.

+- renamed/removed public symbol은 없다. `newOpenAITunnelEndpointEventSource`의 Chat pool, direct tunnel, Responses recovery call site는 `stream_gate_runtime.go`와 `responses_stream_gate.go`에서 모두 같은 request-local codec state를 사용한다.
+
+### 분할 판단
+
+- 단일 plan을 유지한다. semantic event 하나와 exact wire release queue의 순서, terminal event의 exactly-once 시점, source status/error state가 하나의 request-local protocol invariant라 분리하면 중간 상태가 byte identity 또는 Core terminal 계약을 깨뜨린다.
+
+### 범위 결정 근거
+
+- `repeat-guard`, `schema-contract`, `provider-error-retry`의 실제 matcher/repair intent는 후속 Roadmap Task이므로 구현하지 않는다.
+- provider selection/admission policy, ingress snapshot/Rebuilder, Core package API와 recovery budget은 직전 review에서 통과했으므로 변경하지 않는다.
+- 외부 provider smoke, roadmap 상태 갱신, dispatcher-owned `WORK_LOG.md`, 중앙 `agent-ops/rules/common/**`와 `agent-ops/skills/common/**`는 범위 밖이다.
+
+### 최종 라우팅
+
+- `evaluation_mode=isolated-reassessment`, `finalizer=finalize-task-policy.sh`, `finalizer_mode=pair`.
+- Build closures: scope/context/verification/evidence/ownership/decision 모두 `true`; capability gap 없음.
+- Build scores: scope=2, state=2, blast=2, evidence=1, verification=1 → `G08`; base=`local-fit`, `large_indivisible_context=false`.
+- Positive loop risks: `temporal_state`, `concurrent_consistency`, `boundary_contract`, `structured_interpretation`, `variant_product` (`loop_risk_count=5`).
+- Recovery signals: `review_rework_count=3`, `evidence_integrity_failure=true`; base가 local-fit이므로 `recovery-boundary`로 cloud 승격.
+- Build route: `cloud/G08`, `PLAN-cloud-G08.md`.

+## 구현 체크리스트
+
+- [ ] [REVIEW_API-1] Chat/Responses tunnel의 protocol finish와 최종 transport terminal을 분리하고 trailing wire를 byte-identical하게 한 번 release한다.
+- [ ] [REVIEW_API-2] metadata/tool-call/non-2xx를 endpoint semantic event로 정확히 분류하고 stable call identity·unmatched raw error passthrough를 보존한다.
+- [ ] [REVIEW_API-3] production 회귀 fixture와 Stream Evidence Gate current spec/foundation 주석을 실제 동작에 맞춰 갱신한다.

+
+### [REVIEW_API-1] Terminal wire와 single-terminal 상태 전이
+
+- 문제: `apps/edge/internal/openai/stream_gate_tunnel_codec.go:101-120,211-218,297-303`은 Chat `finish_reason` 또는 Responses `response.completed`를 보는 즉시 codec을 terminal로 닫아 같은 body나 다음 tunnel frame의 `[DONE]`을 버린다. source는 terminal event를 반환하면 이후 provider frame을 소비하지 않으므로 sink가 marker를 복구할 수도 없다.
+- 해결 방법:
+
+```go
+// Before: apps/edge/internal/openai/stream_gate_tunnel_codec.go:297-303
+if choice.FinishReason != nil {
+    terminal, _ := streamgate.NewTerminalEvent(streamGateChannelDefault, time.Now())
+    events = append(events, terminal)
+}
+```
+
+```go
+// After: protocol finish는 request-local pending terminal/wire로 stage한다.
+codec.stageProtocolFinish(frame)
+// [DONE] 또는 transport END에서 trailing wire를 모두 결합하고 Terminal을 한 번 emit한다.
+return codec.finishTerminal(endFrame)
+```
+
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: protocol finish, `[DONE]`, END와 terminal wire queue를 분리하고 reset/recovery 격리를 유지한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_runtime.go`: END가 codec의 staged terminal을 flush하고 terminal event를 정확히 한 번 반환하게 한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_release_sink.go`: release/terminal queue가 빈 frame, trailing marker, buffered/nonbuffered 순서를 동일하게 처리하는지 필요한 최소 보정을 한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: Chat finish→`[DONE]`, Responses completed→`[DONE]`, END-only와 split tunnel body를 production source/sink로 검증한다.
+- 테스트 작성: `TestOpenAITunnelCodecTerminalWire`를 작성해 각 입력에서 output bytes가 provider frames와 정확히 같고 terminal event/commit 및 `[DONE]`이 각각 한 번인지 assert한다.
+- 중간 검증: `go test -count=1 ./apps/edge/internal/openai -run 'Test(OpenAITunnelCodecTerminalWire|ResponsesStreamGateEventShapeAndPathSwitch)'`가 exit 0이어야 한다.
+
+### [REVIEW_API-2] Endpoint semantic state와 provider-error lifecycle
+
+- 문제: `apps/edge/internal/openai/stream_gate_tunnel_codec.go:189-199`은 semantic 없는 frame의 raw JSON을 `text_delta`로 만들고, `:279-291,394-409`는 split tool-call의 앞 frame id/name을 보존하지 않는다. `apps/edge/internal/openai/stream_gate_runtime.go:386-449`은 HTTP non-2xx status를 저장하지 않아 오류 body 뒤 END를 success terminal로 만든다.
+- 해결 방법:
+
+```go
+// Before: apps/edge/internal/openai/stream_gate_tunnel_codec.go:189-199
+if len(events) == 0 {
+    semantic := data
+    event, _ := streamgate.NewTextDeltaEvent(streamGateChannelDefault, semantic, time.Now())
+    events = []streamgate.NormalizedEvent{event}
+}
+```
+
+```go
+// After: wire-only prelude와 endpoint call metadata는 semantic content와 분리한다.
+codec.stageWirePrelude(frame)
+codec.rememberToolIdentity(indexOrItemID, callID, name)
+// arguments delta는 기억한 stable identity로 ToolCallFragment를 만든다.
+```
+
+```go
+// After: event source는 response-start status를 attempt-local로 기억한다.
+source.responseStatus = status
+// non-2xx body/END는 sanitized ProviderError terminal을 만들고 raw wire는 unmatched pass release queue에 유지한다.
+```
+
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: metadata/prelude wire queue와 Chat index/Responses item-call identity accumulator를 request-local로 구현한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_runtime.go`: response status/error 상태를 source에 보존하고 transport ERROR·HTTP non-2xx·endpoint error event를 일관된 provider-error terminal로 수렴한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_release_sink.go`: unmatched provider-error foundation에서도 original status/header/body가 한 번 노출되고 raw payload가 관측/오류 문자열로 새지 않게 한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: metadata-only no-text, Chat/Responses split tool identity, non-2xx unmatched raw release와 provider-error outcome을 production runtime으로 검증한다.
+- 테스트 작성: `TestOpenAITunnelCodecSemanticFrames`와 `TestOpenAITunnelHTTPErrorLifecycle`을 작성한다. 전자는 표준 multi-frame call의 ID/name/arguments와 text evidence 부재를, 후자는 HTTP 500 status/header/body byte identity, provider-error filter evaluated-pass, single error terminal, zero recovery를 assert한다.
+- 중간 검증: `go test -count=1 ./apps/edge/internal/openai -run 'Test(OpenAITunnelCodecSemanticFrames|OpenAITunnelHTTPErrorLifecycle|OpenAIProviderErrorFoundation)'`가 exit 0이어야 한다.
+
+### [REVIEW_API-3] Regression evidence와 current spec 정합화
+
+- 문제: `agent-spec/runtime/stream-evidence-gate.md:56,106`은 normalized non-stream Responses가 runtime을 사용하지 않는다고 남아 현재 코드/outer contract와 충돌한다. `apps/edge/internal/openai/stream_gate_filters.go:26-29`도 foundation provider-error가 matched exact replay를 만든다는 stale 주석을 가진다.
+- 해결 방법:
+
+```markdown
+<!-- Before: agent-spec/runtime/stream-evidence-gate.md:106 -->
+- normalized `/v1/responses`는 ... Stream Evidence Gate runtime을 사용하지 않는다.
+```
+
+```markdown
+<!-- After: update-spec 경로로 current implementation만 기록 -->
+- normalized non-stream `/v1/responses`와 지원되는 Chat/Responses tunnel은 gate enabled일 때 request-local runtime을 사용한다.
+- semantic matcher/recovery는 각 후속 filter Task 전까지 foundation lifecycle만 제공한다.
+```
+
+- 수정 파일 및 체크리스트:
+  - [ ] `agent-ops/skills/common/router.md`를 통해 `update-spec` 절차를 적용하고 `agent-spec/runtime/stream-evidence-gate.md`의 source evidence, 범위, 한계, 검증을 현재 코드/계약에 맞춘다. 중앙 common skill 파일 자체는 수정하지 않는다.
+  - [ ] `apps/edge/internal/openai/stream_gate_filters.go`: provider-error foundation 주석을 observed-unmatched pass-only 구현과 일치시킨다.
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: REVIEW_API-1/2 fixture가 S14/S18 exact-wire/split/error evidence임을 test 이름과 assertion으로 명시한다.
+- 테스트 작성: 문서/주석 전용 별도 test는 만들지 않는다. REVIEW_API-1/2 production fixtures와 stale 문구 deterministic search, full/race suite를 사용한다.
+- 중간 검증: `rg --sort path -n 'runtime을 사용하지 않는다|exact_replay intent on a matched' agent-spec/runtime/stream-evidence-gate.md apps/edge/internal/openai/stream_gate_filters.go`가 출력 없이 exit 1이어야 하고 `git diff --check`가 exit 0이어야 한다.
+
+## 의존 관계 및 구현 순서
+
+1. REVIEW_API-1에서 terminal/wire queue 상태를 먼저 고정한다.
+2. REVIEW_API-2가 같은 queue 위에 metadata/tool/error semantics를 연결한다.
+3. REVIEW_API-3이 production evidence와 current spec을 최종 동기화한다.

+
+Go test cache는 허용하지 않는다.
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run 'Test(OpenAITunnelCodecTerminalWire|OpenAITunnelCodecSemanticFrames|OpenAITunnelHTTPErrorLifecycle|ResponsesStreamGateEventShapeAndPathSwitch|OpenAIProviderErrorFoundation)'

+git diff --check
+```
+
+기대 결과: focused/full/race test와 `git diff --check`는 exit 0, `gofmt -l`은 출력 없이 exit 0, stale 문구 `rg`는 출력 없이 exit 1이다. terminal marker와 raw non-2xx body는 byte-identical하며 metadata frame은 text evidence가 아니고 split tool-call identity는 안정적이어야 한다.

+# OpenAI tunnel provider-error 원문 응답 종결 계획
+
+## 이 파일을 읽는 구현 에이전트에게
+
+이 계획의 구현과 검증을 완료한 뒤 active `CODE_REVIEW-cloud-G09.md`의 구현 에이전트 소유 섹션에 실제 변경 내용과 명령 stdout/stderr를 채운다. active PLAN/CODE_REVIEW 파일은 그대로 두고 리뷰 준비 완료만 보고한다. 막히면 정확한 blocker, 실행한 명령/출력, 재개 조건만 구현 소유 evidence에 기록한다. 사용자에게 결정을 묻거나 user-input 도구·control-plane stop 파일을 만들거나 다음 상태를 분류하지 않는다. verdict, log archive, `complete.log`, task archive는 code-review 전용이다.
+
+## 배경
+
+직전 follow-up은 tunnel codec의 finish marker, metadata/tool identity, provider-error semantic terminal과 current spec을 보정했다. 그러나 reviewer의 production Core→release sink 재현에서 unmatched HTTP 500의 status/header/body가 원문 그대로 나가지 않고 IOP 502 `provider_tunnel_error`로 교체됐다. 이번 follow-up은 source가 가진 attempt-local response-start와 opaque error wire를 최종 sink disposition까지 보존하고, 실제 recovery가 선택된 attempt에서만 폐기하는 단일 경계를 닫는다.
+
+## Archive Evidence Snapshot
+
+- 직전 plan: `agent-task/m-openai-compatible-output-validation-filters/plan_cloud_G08_3.log`
+- 직전 review: `agent-task/m-openai-compatible-output-validation-filters/code_review_cloud_G09_3.log`
+- 판정: `FAIL` (`Required=1`, `Suggested=0`, `Nit=0`)
+- Required 요약: non-2xx provider-error terminal에서 Core가 response-start를 commit하지 않아 sink가 staged raw body를 버리고 원래 upstream 500 대신 IOP 502를 쓴다.
+- 영향 파일: tunnel codec state, event source, release sink, production runtime regression fixture.
+- 검증 evidence: 제출 focused/full/race suite와 formatting/diff는 통과했지만 reviewer의 `TestReviewG09RuntimePreservesUnmatchedHTTPErrorWire`가 production Core→sink 결과의 `500`→`502` 변환을 재현했다. 임시 재현 파일은 제거됐다.
+- Roadmap carryover: terminal wire, endpoint semantic state, split tool identity, normalized Responses spec 보정은 유지하고 S14/S18의 unmatched raw provider-error release evidence만 다시 닫는다.

+
+### SDD·계약 기준
+
+- SDD는 `[승인됨]`이고 잠금이 해제됐다. 직접 대상은 S14의 production codec/Core/release·all-complete/single action과 S18의 Chat/Responses lossless endpoint codec이다.
+- outer OpenAI-compatible 계약은 tunnel passthrough에서 provider status/header/body 보존을 요구한다. provider-error foundation이 unmatched pass로 끝난 경우에도 이 wire 계약은 유지돼야 한다.
+- 새 사용자 결정은 필요 없다. SDD/contract가 이미 원문 passthrough와 provider-error lifecycle의 우선순위를 결정한다.
+
+### 테스트 환경 규칙
+
+- `test_env=local`이며 fresh Go test에는 `-count=1`을 사용한다.
+- Edge/OpenAI production path, platform Core/config package, race, formatting과 diff를 검증한다.
+- 외부 provider/dev smoke는 필요 없다. 문제와 성공 조건이 deterministic provider-frame fixture에서 status/header/body 단위로 완전히 재현된다.
+- `<확인 필요>` 값과 test-rule 유지보수는 없다.
+
+### 테스트 커버리지 공백
+
+- 기존 `TestOpenAITunnelHTTPErrorLifecycle`은 event source의 status와 codec terminal queue만 검사하고 `RequestRuntime.Run` 및 `openAITunnelReleaseSink.CommitTerminal`을 통과하지 않는다.
+- Chat/Responses와 stream/buffered 조합에서 unmatched HTTP error의 원래 status/header/body, evaluated-pass, zero recovery, single terminal을 동시에 검증하지 않는다.
+- error JSON이 정상 endpoint payload처럼 보일 때 semantic text/tool evidence로 오인되지 않는 production assertion이 없다.
+
+### 심볼 참조
+
+- public symbol rename/remove는 없다.
+- `openAITunnelCodecStateForSink`는 initial/recovery source와 sink가 공유하는 request-local 상태이며 recovery source 생성 시 `reset`된다. 이 경계를 response-start와 error wire의 attempt-local disposition에 재사용한다.
+- `openAITunnelReleaseSink.CommitTerminal`은 Core가 최종 error terminal을 선택한 뒤의 유일한 HTTP commit 지점이다. recovery 선택 전에는 terminal commit이 발생하지 않고 새 attempt가 codec state를 reset하므로 이전 wire 폐기 조건을 별도 전역 상태로 만들 필요가 없다.
+
+### 분할 판단
+
+- 단일 plan을 유지한다. response-start/status/header와 opaque body, provider-error terminal, recovery/reset, 최종 HTTP commit은 같은 attempt-local 상태 전이이며 분리하면 중간 상태가 다시 원문 wire를 잃는다.
+
+## 구현 판단 기준
+
+- HTTP non-2xx BODY는 endpoint JSON 모양과 무관하게 semantic content/tool evidence로 decode하지 않고 opaque provider wire로 stage한다.
+- Core가 recovery를 선택하면 새 attempt 초기화가 이전 response-start/body를 폐기한다. Core가 provider-error terminal을 최종 commit하면 현재 attempt의 원래 status, sanitized passthrough headers와 body를 정확히 한 번 쓴다.
+- transport 자체가 response-start/raw body 없이 실패한 경우와 recovery candidate rejection은 기존 IOP 오류 terminal을 유지한다.
+
+## 라우팅 결과
+
+- Finalizer: `finalize-task-policy.sh pair grade-boundary false 4 4 true 2 2 2 2 1 official-review 2 2 2 2 1`을 plan 본문 확정 후 정확히 한 번 실행했다.
+- Positive risks: `temporal_state`, `boundary_contract`, `structured_interpretation`, `variant_product` (`loop_risk_count=4`).
+- Recovery signals: `review_rework_count=4`, `evidence_integrity_failure=true`; recovery boundary와 G09 grade boundary가 모두 성립한다.
+- Build scores: scope=2, state=2, blast=2, evidence=2, verification=1 → `G09`.
+- Build route: basis=`grade-boundary`, lane=`cloud`, `PLAN-cloud-G09.md`.
+- Review closures 모두 `true`; scores scope=2, state=2, blast=2, evidence=2, verification=1 → `G09`.
+- Review route: basis=`official-review`, lane=`cloud`, `CODE_REVIEW-cloud-G09.md`, adapter=`codex`, model=`gpt-5.6-sol`, reasoning=`xhigh`.
+
+## 구현 체크리스트
+
+- [ ] [REVIEW_API-1] unmatched HTTP provider-error의 attempt-local response-start와 opaque wire를 recovery/reset부터 최종 sink commit까지 보존한다.
+- [ ] [REVIEW_API-2] Chat/Responses × stream/buffered production runtime 회귀와 fresh full/race evidence로 원문 passthrough를 종결한다.
+- [ ] `CODE_REVIEW-*-G??.md`의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.
+
+### [REVIEW_API-1] Provider-error raw terminal 경계
+
+- 문제: `stream_gate_runtime.go`는 non-2xx END에서 provider-error event를 만들지만 Core의 error terminal은 response-start를 sink에 commit하지 않는다. `stream_gate_release_sink.go:324-359`는 `wroteHeader=false`이면 terminal raw wire와 buffered body를 폐기하고 IOP 502를 쓴다.
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: attempt-local error response-start(status/headers)와 opaque terminal wire를 원자적으로 stage/pop/reset하는 최소 상태를 추가한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_runtime.go`: non-2xx response-start를 shared codec state에 보존하고 BODY를 semantic decode하지 않은 채 raw error wire로 stage한 뒤 END에서 sanitized provider-error terminal만 Core에 전달한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_release_sink.go`: 최종 provider-error terminal에 staged raw response가 있으면 original status/headers/body를 한 번 commit하고, staged raw response가 없는 transport/candidate 오류에만 기존 IOP error를 사용한다.
+- 불변조건: recovery source의 `state.reset()`은 폐기된 attempt wire를 제거하며, sink의 최종 error commit은 오직 현재 attempt wire만 노출한다. success terminal과 post-header transport truncation 동작은 바꾸지 않는다.
+- 중간 검증: 새 production regression이 수정 전 502를 재현하고 수정 후 원래 upstream status/header/body로 통과해야 한다.
+
+### [REVIEW_API-2] Variant production regression과 완료 evidence
+
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: Chat/Responses × stream/buffered table fixture를 실제 source→Core→sink로 실행한다.
+  - [ ] 각 variant에서 원래 500 status, 허용 header, byte-identical body, `WriteHeader` 1회, terminal commit 1회, provider-error evaluated-pass, recovery dispatch 0회를 assert한다.
+  - [ ] 정상 endpoint payload처럼 보이는 non-2xx body를 포함해 text/tool semantic evidence로 변환되지 않음을 assert한다.
+  - [ ] 기존 finish marker, split tool identity, normalized/tunnel path-switch 회귀를 함께 fresh 실행한다.
+- 테스트 작성: `TestOpenAITunnelHTTPErrorRawPassthroughRuntime`을 추가하고 기존 source-only lifecycle test는 codec 단위 보조 evidence로 유지한다.
+
+## 의존 관계 및 구현 순서
+
+1. REVIEW_API-1에서 shared codec state와 non-2xx opaque ingestion을 고정한다.
+2. 같은 항목에서 sink의 최종 raw error response commit과 기존 fallback 분기를 연결한다.
+3. REVIEW_API-2가 네 endpoint/stream variant와 기존 회귀를 production runtime에서 검증한다.

+# PLAN - 출력 검증 foundation 경로·정책 교정
+
+## 이 파일을 읽는 구현 에이전트에게
+
+이 계획의 구현과 fresh 검증을 완료한 뒤 `CODE_REVIEW-cloud-G10.md`의 구현 에이전트 소유 섹션에 실제 변경·설계 결정·stdout/stderr를 채운다. active PLAN/review 파일은 그대로 두고 review ready만 보고한다. 막히면 정확한 blocker, 실행 명령과 출력, 재개 조건만 구현 evidence에 기록한다. 사용자에게 선택을 묻거나 user-input 도구·control-plane stop 파일을 만들거나 다음 상태를 분류하지 않는다. log archive, `complete.log`, 최종 판정은 code-review 전용이다.
+
+## 배경
+
+두 번째 review는 설정·filter 등록 자체는 추가됐지만 실제 production path와 계약이 여전히 어긋남을 확인했다. Responses normalized 실행은 Core를 우회하고 tunnel은 endpoint body를 semantic event로 해석하지 않으며, selector/admission은 `observe_only`, environment, model group과 queued re-resolution을 잘못 처리한다. 이번 follow-up은 의미 필터 후속 Task를 선반영하지 않고 foundation Task의 정책·codec·evidence 경계만 안전하게 닫는다.

+
+### SDD 기준
+
+- SDD: `agent-roadmap/sdd/knowledge-tool-optimization-extension/openai-compatible-output-validation-filters/SDD.md`, 상태 `[승인됨]`, 잠금 `해제`.
+- `contract-doc` → S01: active outer/inner contract와 handler/config type을 실제 foundation 동작에 맞춘다.
+- `filter-pipeline` → S02: rolling/terminal/error-event-only lifecycle, blocking/observe enforcement, unsupported pre-admission 400을 증명한다.
+- `filter-policy` → S08/S13: request snapshot, actual target re-resolution, caller-neutral selector를 증명한다.
+- `stream-gate-adoption` → S14/S21: 두 endpoint의 complete outcome barrier와 bounded ingress/rebuild 경계를 증명한다.
+- `responses-codec` → S18: Responses endpoint 전용 parsing/release/rebuild, unknown/encrypted input 보존, path switch와 single opening/terminal을 증명한다.
+- Evidence Map의 S01/S02/S08/S13/S14/S18/S21 행을 각각 REVIEW_API-1~4의 regression fixture와 최종 fresh 명령에 직접 연결했다. `repeat-guard`, `schema-contract`, `provider-error-retry`의 의미 판정 Scenario는 이번 Roadmap Targets가 아니므로 구현하지 않는다.
+
+### 테스트 환경 규칙
+
+- `test_env=local`이며 `agent-test/local/rules.md`를 읽었다. matched profile은 `edge-smoke.md`와 `platform-common-smoke.md`다.
+- setup은 `go version && go env GOMOD`, 필수 baseline은 `go test -count=1 ./packages/go/streamgate ./apps/edge/internal/openai`와 `go test -count=1 ./packages/go/streamgate ./packages/go/config`다.
+- service queue 변경은 profile 밖이므로 repository Go package test와 `-race`를 보완 oracle로 추가한다. 캐시 결과는 허용하지 않고 전부 `-count=1`로 실행한다.
+- rule의 기대 runtime은 Go 1.24이고 checkout은 Go 1.26.2지만 module load와 fresh tests가 성공해 blocker가 아니다. 외부 provider/runtime/credential은 사용하지 않는다.
+
+### 테스트 커버리지 공백
+
+- base disabled selector enable, environment/model_group precedence, observe-only non-gating: 미검증.
+- 최초 admission과 queued/recovery re-resolution의 all-rejected 동일 400·zero dispatch/reservation: 미검증.
+- normalized Responses의 Core registry/release adoption: 미구현·미검증.
+- Chat/Responses tunnel의 endpoint semantic event parsing과 path-preserving release: 미구현·미검증.
+- Responses response-start/text/reasoning/function-call/terminal split, path switch, single opening/terminal: 미검증.
+- provider-error foundation이 arbitrary error를 exact replay하지 않는 경계: 현재 반대로 구현·검증됨.
+- S21의 Responses limit-1/limit/limit+1과 typed-view zero-dispatch: 미검증. Chat 일부만 기존 test가 검증한다.
+
+### 심볼 참조
+
+- 현재 rename/remove된 symbol은 없다. 새 환경/model-group snapshot field나 queue terminal outcome을 도입할 때 `openAIOutputFilterContext`, `openAIOutputFilterRequestContext`, `openAIStreamGateCandidatePredicate`, `filterProviderPoolCandidates`, `resolveQueuedCandidatesLocked`, `pumpOnceLocked`의 모든 call site를 함께 갱신한다.
+
+### 분할 판단
+
+- 단일 plan을 유지한다. filter activation/admission과 endpoint codec/release가 따로 PASS하면 unsupported filter의 silent pass 또는 all-complete 전 commit이 가능하므로 하나의 request snapshot + actual target + commit invariant로 함께 닫아야 한다. queue/recovery와 두 endpoint/두 path를 별도 child로 분리해도 독립적으로 안전한 중간 production state를 만들 수 없다.
+
+### 범위 결정 근거
+
+- `packages/go/streamgate`의 Core arbitration/budget은 재구현하지 않는다.
+- `repeat-guard`, `schema-contract`, `provider-error-retry`, `resume-notice-builder`, `ops-evidence`, `length-continuation`의 의미 판정은 별도 Milestone Task이므로 제외한다.
+- 특히 provider error `code`/`message` matcher를 이번 plan에 몰래 추가하지 않는다. foundation은 arbitrary error에 recovery intent를 내지 않게 fail-safe로 되돌리고 active 계약이 실제 상태를 과장하지 않게 한다.
+- 외부 provider smoke, roadmap 상태 변경, `WORK_LOG.md` 수정은 제외한다.
+
+### 최종 라우팅
+
+- `status=routed`, `evaluation_mode=isolated-reassessment`, `finalizer=finalize-task-policy.sh`, `finalizer_mode=pair`.
+- build closures: scope/context/verification/evidence/ownership/decision 모두 true. scores=`2/2/2/2/2`, grade=`G10`, base/route=`grade-boundary`, lane=`cloud`, filename=`PLAN-cloud-G10.md`.
+- review closures: 모두 true. scores=`2/2/2/2/2`, route=`official-review`, lane=`cloud`, grade=`G10`, filename=`CODE_REVIEW-cloud-G10.md`, adapter=`codex`, model=`gpt-5.6-sol`, effort=`xhigh`.
+- `large_indivisible_context=true`; positive loop risks=`temporal_state`, `concurrent_consistency`, `boundary_contract`, `structured_interpretation`, `variant_product` (5).
+- recovery signals: `review_rework_count=2`, `evidence_integrity_failure=true`; risk/recovery boundary도 match하지만 G10의 route basis는 `grade-boundary`를 유지한다. capability gap은 없다.
+
+## 구현 체크리스트
+
+- [ ] [REVIEW_API-1] request snapshot의 environment/model-group/base-selector precedence를 실제 target에 적용하고 blocking filter만 capability admission에 사용하며 최초·queued·recovery all-rejected를 동일 zero-dispatch 400으로 끝낸다.
+- [ ] [REVIEW_API-2] Chat/Responses endpoint별 codec을 tunnel/normalized path 모두의 Core runtime에 연결하고 Responses shape, lossless rebuild, single opening/terminal과 all-complete commit barrier를 보존한다.
+- [ ] [REVIEW_API-3] foundation filter가 후속 의미 Task를 선반영하지 않도록 arbitrary provider-error exact replay와 semantic 과장 표현을 제거하고 outer/inner contract·config example을 실제 동작과 동기화한다.
+- [ ] [REVIEW_API-4] S01·S02·S08·S13·S14·S18·S21 Evidence Map의 deterministic production-path fixture, raw-free sentinel, ingress/rebuild 경계를 fresh test로 증명한다.
+- [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.
+
+### [REVIEW_API-1] Policy snapshot과 admission terminal 교정
+
+- 문제: `stream_gate_policy.go:88-106`은 base-disabled filter를 제거하고 모든 registration을 enabled/required로 만든다. `stream_gate_policy.go:238-245`는 model group에 endpoint를 넣고 `stream_gate_runtime.go:23`은 environment를 `edge`로 고정한다. `provider_pool.go:112-120`은 queued re-resolution의 all-rejected 신호를 버려 400 대신 unavailable/timeout으로 바꾼다.
+- 해결 방법:
+
+```go
+// Before: apps/edge/internal/openai/stream_gate_policy.go:88-106
+if !fc.EffectiveEnabled() { continue }
+reg, err := streamgate.NewFilterRegistration(filter, fc.EffectiveCapability(), true, enforcement, timeout, priority)
+```
+
+```go
+// After: base layer도 snapshot에 보존하고 실제 target에서 effective policy를 resolve한다.
+reg := NewFilterRegistration(filter, capability, fc.EffectiveEnabled(), enforcement, timeout, priority)
+resolved := requestSnapshot.ResolveAttempt(actualTarget)
+required := capabilitiesOf(resolved, BlockingOnly)
+```
+
+  config의 `environment`와 request model group을 request-start snapshot에 넣고 selector-enabled override를 허용한다. queue resolver는 policy rejection을 recoverable resolver fault나 provider absence로 바꾸지 않고 typed terminal error로 waiter에게 전달한다.
+- 수정 파일 및 체크리스트:
+  - [ ] `packages/go/config/edge_types.go`, `configs/edge.yaml`: environment default/validation과 selector 의미를 고정한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_policy.go`, `stream_gate_runtime.go`: 실제 environment/model group과 blocking-only capability를 resolve한다.
+  - [ ] `apps/edge/internal/service/provider_pool.go`, `model_queue_admission.go`, `model_queue_types.go`: queued policy rejection terminal을 보존한다.
+  - [ ] `packages/go/config/stream_evidence_gate_config_test.go`, `apps/edge/internal/openai/stream_gate_policy_test.go`, `apps/edge/internal/service/provider_pool_admission_test.go`: 회귀를 작성한다.
+- 테스트 작성: `TestOpenAIStreamGatePolicyTargetMatrix`, `TestOpenAIStreamGateObserveOnlyDoesNotGateAdmission`, `TestProviderPoolQueuedPredicateRejectionIsTerminal`을 table-driven으로 작성한다. dev/dev-corp, qwen/gemma/ornith model group, provider 전환, base false→selector true, blocking/observe, zero reservation/dispatch와 `ErrProviderPoolCandidateRejected` identity를 assert한다.
+- 중간 검증: `go test -count=1 ./packages/go/config ./apps/edge/internal/service ./apps/edge/internal/openai -run 'Test(StreamGateFilterPolicy|OpenAIStreamGatePolicy|ProviderPoolQueuedPredicate)'`가 exit 0이어야 한다.
+
+### [REVIEW_API-2] Endpoint codec과 Responses runtime 채택
+
+- 문제: `responses_handler.go:130-151,464-480`은 normalized Responses를 gate 밖의 `completeResponse`로 보낸다. `stream_gate_runtime.go:306-311`은 tunnel body를 opaque `text_delta`로 취급하고 `stream_gate_filters.go:116-120`은 repeat/schema를 tunnel에서 제외한다. `stream_gate_runtime.go:552-566`은 tunnel schema metadata도 지운다.
+- 해결 방법:
+
+```go
+// Before: apps/edge/internal/openai/responses_handler.go:478-480
+s.completeResponse(w, preparedDispatch, handle)
+```
+
+```go
+// After: 실제 selected path의 endpoint codec을 고른 뒤 같은 request runtime으로 수렴한다.
+codec := responsesCodecFor(transport)
+source := codec.EventSource(transport) // response-start/text/reasoning/function-call/terminal
+sink := codec.ReleaseSink(writer)      // Responses shape, one opening/terminal
+return runResponsesStreamGate(snapshot, source, sink, rebuilder)
+```
+
+  Chat/Responses raw parser는 분리하고 tunnel/normalized execution path는 그대로 둔다. codec은 semantic event를 filter에 제공하면서 caller-facing endpoint framing과 unknown/encrypted request item의 lossless rebuild를 보존한다. schema presence를 tunnel context에서도 유지하며 complete outcome 전 status/header/opening/content를 쓰지 않는다.
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/responses_handler.go`, `responses_completion.go`, `responses_types.go`: normalized Responses를 request runtime과 endpoint-native sink에 연결한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_runtime.go`, `stream_gate_release_sink.go`: Chat/Responses × tunnel/normalized codec selection과 path-switch를 연결한다.
+  - [ ] `apps/edge/internal/openai/stream_gate_filters.go`: execution path만으로 foundation filter를 누락하지 않는다.
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`, `openai_request_rebuilder_test.go`: endpoint shape와 lossless rebuild fixture를 확장한다.
+- 테스트 작성: `TestStreamGateEndpointPathMatrix`, `TestResponsesStreamGateEventShapeAndPathSwitch`, `TestTunnelSchemaContextPreserved`를 작성한다. response-start, split text/reasoning/function call, terminal/error, tunnel↔normalized pre-commit switch, unknown/encrypted input, single opening/terminal, no eager header를 assert한다.
+- 중간 검증: `go test -count=1 ./apps/edge/internal/openai -run 'Test(StreamGateEndpointPathMatrix|ResponsesStreamGate|TunnelSchema)'`가 exit 0이어야 한다.
+
+### [REVIEW_API-3] Foundation filter 범위와 active contract 동기화
+
+- 문제: `stream_gate_filters.go:177-194`는 matcher 없이 모든 provider error를 `matched`로 명명하고 exact replay한다. 같은 파일의 repeat/schema는 후속 의미 Task 범위라 pass-only인데 contract/YAML/review는 semantic protection 완료처럼 설명한다.
+- 해결 방법:
+
+```go
+// Before: apps/edge/internal/openai/stream_gate_filters.go:177-194
+if kind == providerError && batchHasProviderError(batch) {
+    return violationWithExactReplay("provider_error_matched")
+}
+```
+
+```go
+// After: foundation은 lifecycle outcome만 만들고 의미 Task 전에는 recovery action을 만들지 않는다.
+if kind == providerError && batchHasProviderError(batch) {
+    return evaluatedPass("provider_error_observed_unmatched")
+}
+```
+
+  `provider-error-retry` Task의 code/message matcher 없이는 `matched`/exact replay를 만들지 않는다. repeat/schema도 rolling/terminal lifecycle participant라는 현재 범위만 명시하고 실제 detection/validation이 활성이라고 문서화하지 않는다.
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_filters.go`, `stream_gate_filters_test.go`: arbitrary error no-recovery와 outcome lifecycle을 고정한다.
+  - [ ] `agent-contract/outer/openai-compatible-api.md`, `agent-contract/inner/edge-config-runtime-refresh.md`, `configs/edge.yaml`: foundation과 후속 의미 Task 경계를 active behavior 기준으로 정정한다.
+- 테스트 작성: `TestOpenAIProviderErrorFoundationDoesNotReplayUnmatchedError`와 rolling/deferred/not-applicable matrix를 작성한다. recovery intent nil, raw-free descriptor, blocking/observe error policy는 Core가 소유함을 assert한다.
+- 중간 검증: `go test -count=1 ./apps/edge/internal/openai -run 'TestOpenAI(OutputFiltersOutcomeMatrix|ProviderErrorFoundation)'`와 `git diff --check`가 통과해야 한다.
+
+### [REVIEW_API-4] SDD Evidence Map closure
+
+- 문제: 현재 `stream_gate_pipeline_test.go:13-71` 한 건과 pure helper/rebuilder test만으로는 S01/S02/S08/S13/S14/S18/S21의 production path를 증명할 수 없다.
+- 해결 방법: REVIEW_API-1~3의 fixture를 SDD scenario id별 table case로 묶고 HTTP handler→service admission→Core→release의 실제 경로를 호출한다. raw sentinel은 input/provider output/tool/auth에 넣고 observation 및 외부 output에 금지된 값이 없음을 검사한다. Responses ingress limit-1/limit/limit+1, typed-view/rebuild overflow는 zero dispatch/budget과 release를 함께 검사한다.
+- 수정 파일 및 체크리스트:
+  - [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: S02/S13/S14/S18 path matrix와 raw-free evidence.
+  - [ ] `apps/edge/internal/openai/stream_gate_ingress_test.go`: Chat/Responses S21 boundary와 zero-dispatch.
+  - [ ] `apps/edge/internal/openai/openai_request_rebuilder_test.go`: Responses retained/rebuild overflow 및 unknown/encrypted item 보존.
+  - [ ] `apps/edge/internal/openai/stream_gate_policy_test.go`, `apps/edge/internal/service/provider_pool_admission_test.go`: S08 actual-target/queue evidence.
+  - [ ] `packages/go/config/stream_evidence_gate_config_test.go`: S01 config default/range/duplicate/selector evidence.
+- 테스트 작성: 위 fixture를 반드시 작성한다. caller-neutral S13은 caller 이름 field 없이 동일 protocol payload 세 변형을 같은 decision/path로 비교한다. 기존 test가 assertion을 이미 충족하면 중복 test 대신 해당 정확한 test name과 stdout을 review evidence에 기록한다.
+- 중간 검증: `go test -race -count=1 ./apps/edge/internal/service ./apps/edge/internal/openai`와 `go test -count=1 ./packages/go/streamgate ./packages/go/config`가 exit 0이어야 한다.
+
+## 의존 관계 및 구현 순서
+
+REVIEW_API-1의 immutable policy/admission을 먼저 고정하고 REVIEW_API-2가 그 snapshot을 소비하게 한다. REVIEW_API-3의 safe foundation behavior와 contract를 같은 변경 세트에서 맞춘 뒤 REVIEW_API-4가 전체 production path를 검증한다. 중간 commit이나 부분 완료를 PASS로 취급하지 않는다.

+//   - provider_error: error-event-only participant -> not-applicable on a clean
+//                     epoch and observed-unmatched pass on a provider error.
+//                     Matcher and recovery intent construction remain follow-up
