The effective route binds one principal, slot, profile, upstream model, resource selector, credential revision, route revision, and projection generation; caller metadata and legacy provider-auth headers cannot replace any binding field.
 - `openai.principal_tokens[]`는 raw token을 저장하지 않고 hash/reference로 principal 매핑을 관리한다. 각 entry는 `token_ref` (non-empty, unique), `token_hash_sha256` (64-char hex, duplicate hash rejection), `principal_ref` (non-empty), optional `principal_alias` 필드를 갖는다. 여러 entry가 같은 `principal_ref`와 `principal_alias`를 공유할 수 있으며, 이때 `token_ref`가 앱/통합/용도별 사용량 분해 기준이 된다. tracked config에는 raw token을 저장하지 않고 hash/reference만 둔다.
 - `protocol_profiles` is the top-level map of custom profile overlays, keyed by stable profile id. Each `ProtocolProfileConf` can declare `base`, `driver`, `base_url`, an operation-path map, `auth`, `capabilities`, `model_mapping`, `normalization`, and `extensions`. A custom overlay extends one built-in or custom base; cycles, unknown bases, and invalid driver/operation/capability combinations are rejected during config normalization.
-- `normalization.effort[operation]` declares the provider wire, supported normalized grades, whether the operation preserves effort with caller tools, and whether it preserves an explicit thinking token budget. Every normalization operation must exist in the profile operation map. Grade keys use `none|low|medium|high|xhigh|max`; exact miss falls back only to the nearest declared lower key. A canonical mapped value above its source key is rejected so config cannot silently upgrade requested effort.

A canonical mapped value above its source key is rejected so config cannot silently upgrade requested effort. This Edge-local selection fact is consumed before tunnel dispatch and is not serialized into a new caller or Edge-Node wire field. The built-in `gemini` Chat Completions operation declares only `low`, `medium`, `high`; `xhigh` and `max` fall through the common normalizer to `high`, and `none` is rejected because it is not declared.
+- `normalization.tool_calls[operation].wire` declares operation-scoped provider tool-call metadata normalization independently from effort mapping. The only current value is `gemini_openai_chat`; the built-in `gemini` Chat Completions operation declares it, custom overlays inherit it, and unknown wires or undeclared operations fail config validation. This runtime-only fact is attached to the selected dispatch and is not a caller selector or a new Edge-Node field.
 - `nodes[].providers[].profile` selects a built-in or custom catalog entry. If the selector is empty, legacy provider-type normalization can select a compatibility profile; this is distinct from `base` inheritance. Normalization resolves the selection into the runtime-only `ProviderDefinition.RuntimeProfile` snapshot, which is not serialized back into YAML. The resolved snapshot is copied into the nested OpenAI-compatible adapter config, not into a per-request tunnel message.
 - `ConcreteProtocolProfile.MapModel(model)`은 provider의 model alias 정규화를 수행한다. provider가 model mapping을 정의하면 IOP external `model` key를 provider served target으로 변환한다. 매핑이 없으면 original model을 그대로 사용한다.
 - `ConcreteProtocolProfile.HasCapability(cap)`는 provider capability admission에 사용된다. closed vocabulary (`models`, `chat`, `messages`, `responses`, `streaming`, `tool_calling`, `count_tokens`)만 허용한다.

-- provider-pool model group route(`models[]`)의 `/v1/responses` 호출은 selected provider가 Responses operation/capability와 요청의 tool/effort semantics를 선언한 tunnel candidate이면 provider `POST /v1/responses`에 전달한다. This admission is not exclusive to the `openai_responses` driver. caller body는 served target과, 필요한 경우 operation별로 매핑된 `reasoning.effort`만 rewrite하고 `max_output_tokens`, `tools`, `store`, provider-specific knobs 및 `reasoning`의 다른 field는 보존한다. `stream:true`는 provider raw SSE로 relay한다. Managed mode injects the selected slot lease at the Node; legacy mode may apply configured provider-auth forwarding. Response model echo rewrite is not applied, and this path never falls back to normalized `SubmitRun`.
+- provider-pool model group route(`models[]`)의 `/v1/responses` 호출은 concrete protocol profile이 선택한 wire로 tunnel dispatch한다. Native Responses operation은 served target과 operation별 `reasoning.effort`만 rewrite하고 body/SSE를 raw passthrough한다. Anthropic Messages 또는 OpenAI Chat profile은 `instructions`, message/input, function call/result, tools, tool choice, parallel calls, output limit, stream, structured output 및 선언된 reasoning mapping을 모두 보존할 수 있을 때만 각각 `/v1/messages` 또는 `/v1/chat/completions`로 변환한다. Bridge 응답은 canonical Responses JSON/SSE로 다시 렌더하며 provider-native framing을 caller에게 노출하지 않는다. 표현 불가능한 control은 provider dispatch 전에 `400 invalid_request_error`로 거부한다. 이 선택은 caller/SDK identity가 아니라 request requirement와 profile에만 따른다.
+- Gemini Chat bridge의 `extra_content.google.thought_signature`는 opaque Responses `call_id`에 캡슐화한다. caller가 후속 `function_call_output`에 그 값을 replay하면 Edge가 original tool id와 signature를 복원한다. Managed mode injects the selected slot lease at the Node; legacy mode may apply configured provider-auth forwarding. 이 경로도 normalized `SubmitRun`으로 fallback하지 않는다.
 - provider-pool model group route는 provider candidate를 먼저 선택한다. 선택된 provider가 OpenAI-compatible 호출 방식을 지원하면 `ProviderTunnelRequest` passthrough를 사용하고, Ollama/native provider이면 normalized `RunRequest`를 사용한다. provider type만으로 Ollama를 candidate set에서 제거하지 않으며, OpenAI-compatible provider의 tunnel 구현이 없으면 normalized fallback이 아니라 unsupported/implementation error다.
 - provider-pool pending request는 lease 반환, config refresh, provider disable, Node disconnect/reconnect 때 live config와 dispatch-ready registry에서 candidate를 다시 계산한다. 후보가 full인 상태는 queue policy에 따라 계속 대기하지만 live candidate가 모두 사라지면 원래 queue timeout까지 기다리지 않고 terminal unavailable로 끝난다.
 - provider-pool admission/unavailable 실패는 현재 외부 error envelope를 유지해 HTTP `502`와 `type="node_dispatch_error"`로 반환한다. 별도 public status code나 response field를 추가하지 않으며 error message에는 raw token이나 private endpoint를 포함하지 않는다.

 - `metadata`는 경로 선택자가 아니다. Edge는 route 결정 뒤 인증 principal, usage/observability 등 IOP가 아는 bounded metadata key만 발췌한다. 이 발췌 정보는 provider body를 바꾸는 selector가 아니며, passthrough 응답 body에 IOP marker/event/envelope를 섞지 않는다.
 - Chat Completions 성공 응답의 top-level `model` echo가 provider-served model이면 caller가 요청한 IOP model alias로 정규화할 수 있다. reasoning/content/tool_calls 같은 provider payload field는 보존한다.
+- Selected protocol profile의 `normalization.tool_calls.chat_completions.wire`가 `gemini_openai_chat`일 때만 Edge는 Gemini의 opaque `extra_content.google.thought_signature`를 표준 `tool_calls[].id` 안에 캡슐화하고 provider extension field를 caller 응답에서 제거한다. Caller는 받은 tool-call id를 assistant history와 tool result의 `tool_call_id`에 변경 없이 replay해야 한다. 다음 요청에서 Edge는 원래 id와 signature를 복원해 Gemini provider에 전달한다. 다른 profile, signature 없는 Gemini 응답, tool call 없는 응답에는 적용하지 않으며 caller/SDK 이름으로 분기하지 않는다. IOP prefix를 가진 malformed id와 충돌하는 signature는 provider dispatch 전에 거부한다.

In `prepare-follow-up`, treat the reviewer's closed finding packet as the decision authority: repository reads validate its consistency and supply implementation mechanics, but do not reopen root cause or solution selection. If required evidence, root cause, or a selected fix is missing or contradicted, return `needs_evidence` to code-review so the reviewer corrects it in the same review pass; never pass investigation or alternatives to the worker.

In `prepare-follow-up`, require the reviewer to have collected every fact needed for diagnosis and fix selection; derive only mechanical command/path details, and return `needs_evidence` rather than performing missing review analysis.

+- Roadmap: [ROADMAP.md](../../../../ROADMAP.md)
+- Phase: [PHASE.md](../../../../phase/knowledge-tool-optimization-extension/PHASE.md)
+
+## 목표
+
+벤치마크에 사용할 caller/model/route 조합만 고정된 최소 HTML 생성 요청으로 빠르게 확인한다.
+IOP 전체 안정성을 처음부터 재검증하지 않고, 실패가 재현된 경로만 제품·caller·provider·환경 중 한 경계에 귀속해 국소 수정한 뒤 그 경로만 다시 확인한다.
+
+## 상태

+## 구현 잠금
+
+- 상태: 해제
+- SDD: 필요
+- SDD 문서: [SDD.md](../../../sdd/knowledge-tool-optimization-extension/benchmark-route-minimal-html-smoke/SDD.md)
+- 잠금 해제 조건:
+  - [x] SDD 잠금이 해제되어 있다
+  - [x] SDD 사용자 리뷰가 없거나 승인/해결되었다
+  - [x] Acceptance Scenario가 Milestone 기능 Task와 연결되어 있다
+  - [x] Evidence Map이 완료 시 `complete.log` 첫 줄의 `milestone-task` id별 집계와 최종 검증 evidence로 검증 가능하게 연결되어 있다
+- SDD 사유: OpenCode direct 실측이 Gemini Chat thought-signature 왕복 결함을 재현했고, 이를 caller 예외가 아닌 operation-scoped protocol profile config와 외부 Chat tool-call 계약으로 고정해야 한다.
+- 결정 필요: 없음
+
+## 범위
+
+- 아래 9개 기존 벤치 대상 조합을 순서와 무관하게 한 경로씩 직접 실행한다.
+  - Claude Code → Claude direct
+  - Claude Code → Gemini direct
+  - OpenCode → Gemini direct
+  - Claude Code → GPT direct
+  - Codex → GPT direct
+  - Claude Code → Gemini execution preset
+  - OpenCode → Gemini execution preset
+  - Claude Code → GPT execution preset
+  - Codex → GPT execution preset
+- 모든 경로에 같은 구현 요구를 사용한다: 외부 asset과 JavaScript 없이 exact marker가 있는 단일 `index.html`을 구현하고 종료한다.
+- 각 경로는 최초 1회만 실행하고 120초 안에 terminal을 확인한다. direct 경로는 caller workspace의 `index.html`, Edge-owned execution preset은 비공개 workspace 정리 계약 때문에 caller 로컬 파일이 아니라 caller-visible `decision.output`의 완료·marker를 판정한다.
+- 실패하면 자동 retry나 전체 재실행을 하지 않는다. sanitized terminal/error와 IOP request stage만 확인해 소유 경계를 정하고, 변경된 원인이 있을 때 실패 경로만 1회 재검증한다.
+- 제품 코드를 수정한 결함에는 해당 소유 package의 focused regression test를 추가하고 관련 Go test를 실행한다.
+
+## 기능
+
+### Epic: [route-smoke] 벤치 경로 초경량 확인
+
+- [x] [minimal-html-calls] 9개 조합에 동일한 최소 HTML 구현 요청을 한 번씩 직접 실행하고, 경로별 caller/model/route, terminal, 경과 시간, marker 확인 결과를 한 개의 Markdown 표에 기록한다. direct는 caller workspace 파일, Edge-owned execution preset은 caller-visible terminal output을 확인한다. 사설 dev CA가 필요한 호출은 caller가 공식 지원하는 command-scoped CA 변수에 managed CA bundle을 전달한다. Codex는 `CODEX_CA_CERTIFICATE`, Node 기반 caller는 필요한 경우 `NODE_EXTRA_CA_CERTS`를 사용한다. 검증: 새 runner/manifest 없이 각 행에 실제 호출 결과가 하나만 있어야 하며, 호출 전후 ambient Codex/IDE/shell 환경에는 CA 변수가 없어야 한다.
+- [x] [failed-path-fixes] 실패한 조합마다 제품·caller·provider·환경 중 소유 경계를 기록하고, IOP 제품 결함이 재현된 경우에만 국소 수정과 focused regression을 수행한 뒤 해당 조합만 다시 호출한다. 검증: 성공한 조합의 반복 실행이 없고, 재실행 행에는 변경된 원인과 연결된 수정·테스트 근거가 있어야 한다.
+- [x] [thin-bench-handoff] 9개 조합의 통과 또는 구체적 외부 차단 상태를 짧게 정리해 `[bench-lite-01]` 실행 가능 여부를 남긴다. 검증: 비교 점수나 순위가 아니라 호출 가능 여부와 남은 소유자만 기록한다.
+
+## 완료 리뷰
+
+- 상태: 통과
+- 요청일: 2026-08-14
+- 완료 근거: 동일한 최소 HTML 요청으로 9개 caller/model/route 경로가 모두 통과했다. 실패 경로는 제품·provider·환경 경계로 귀속해 원인 변경 뒤에만 재검증했고, IOP 결함은 provider normalization과 focused regression으로 한정해 수정했다.
+- 검토 항목:
+  - [x] 새 benchmark script, runner, manifest, state store가 생성되지 않았다.
+  - [x] 성공 경로는 한 번만 실행했고 실패 경로만 변경된 원인 뒤 재검증했다. 단, 사용자 지시의 세션 한정 hybrid Work 모델 전환 확인은 경로 복구 검증과 분리해 기록했다.
+  - [x] 제품 수정은 재현된 결함과 focused regression으로 한정됐다.
+- agent-ui 상태 반영: 해당 없음
+- Spec sync: [OpenAI-Compatible 입력 표면](../../../../../agent-spec/input/openai-compatible-surface.md)에 operation-scoped normalization, nearest-lower effort, Gemini Chat signature 왕복과 관련 코드·테스트 evidence가 이미 반영되어 추가 갱신이 필요하지 않다.
+- 리뷰 코멘트: 2026-08-14 종료 감사를 통과했다. 관련 config/OpenAI/service 회귀 테스트와 9/9 dev 실호출 evidence를 확인했으며 제품·호출 경로 차단은 남지 않았다. `[bench-lite-01]`의 단일 시도 비교를 시작할 수 있다. 표준 release tag finish는 다른 active release와 충돌하므로 배포 성공 판정과 분리해 남겨 둔다.

+
+## 작업 컨텍스트
+
+- 계획 범위: 짧은 단일 test plan으로 즉시 실행할 수 있게 유지한다. 별도 설계·SDD·다단계 복구 계획으로 확장하지 않는다.
+- 실행 방식: 기존 공식 caller 명령을 한 번씩 직접 실행한다. 공통화가 필요해 보여도 이 Milestone에서는 script로 승격하지 않는다.
+- TLS 환경 경계: 개발 Edge용 사설 CA는 Edge leaf 인증서가 아니라 managed CA bundle을 해당 벤치 caller process에만 전달한다. Codex에는 공식 변수 `CODEX_CA_CERTIFICATE`, Node 기반 caller에는 필요한 경우 `NODE_EXTRA_CA_CERTS`를 사용하며 Codex/IDE 시작 환경이나 셸 전역에 `export`하지 않는다. 그렇지 않으면 공개 TLS 연결에도 같은 CA override가 적용될 수 있다.
+- evidence 위치: `agent-test/dev/iop-benchmark-route-minimal-html-smoke.md`
+- 현재 사전 확인: 2026-08-13 실제 원격 실행기에서 Claude Code 2.1.177과 Codex 0.146.0을 확인했고, 현재 workspace의 OpenCode 1.18.3을 별도 사용자 설정 변경 없이 command-scoped provider config로 준비했다. 원격 SOPS에 보관된 기존 IOP principal token으로 token 원문을 출력하지 않은 `/v1/models`가 HTTP 200임을 확인했다. 새 벤치 전용 token은 발급하거나 사용하지 않는다.
+- 현재 경로 결과: 9개가 모두 통과했다. Claude Code → GPT direct는 caller-neutral operation normalization 반영 뒤 9초, Codex → GPT direct와 Codex → GPT execution preset은 각각 10초/16초에 통과했다. OpenCode → Gemini execution preset은 `ornith-fast` Node 복구 뒤 19초에 통과했다. 이후 사용자 지시로 이 세션의 hybrid Work 바인딩만 `ornith:35b`로 임시 전환했고, Claude Code → GPT execution preset은 71초, OpenCode → Gemini execution preset은 51초에 terminal success·caller marker·오류 0으로 통과했다. 마지막 OpenCode → Gemini direct는 normalization 포함 dev 배포 뒤 11초에 `glob`/`write`/`read`, terminal marker, exact `index.html`을 확인했다.
+- 추가 분리 결과: agy는 text completion은 가능하지만 trusted workspace에서도 파일 도구를 호출하지 않아 구현 Agent 벤치 대상에서 제외했다. 대체한 OpenCode → Gemini direct는 첫 tool 호출 뒤 `extra_content.google.thought_signature`를 일반 Chat history로 보존하지 못해 두 번째 provider 호출이 HTTP 400으로 닫혔다. IOP가 선택된 `gemini_openai_chat` tool-call wire에서만 opaque id로 캡슐화·복원하도록 공통 provider normalization을 추가했고 focused HTTP 연속 호출 회귀와 live tool continuation이 통과했다. Codex → GPT direct의 최초 실패는 CA bundle 대신 Edge leaf 인증서를 전달한 측정 환경 결함이었다. Claude Code → Gemini/GPT preset의 이전 default-selector 및 profile operation normalization 결함도 국소 수정과 회귀 검증이 완료됐다.
+- 배포 경계: source `de35e6d4`로 Edge와 네 Node를 다시 빌드·배포했고 빌드 전후 Go package 49개, Node/provider health, managed-capacity Chat·Responses 네 건을 통과했다. 배포 source는 `archive/release-dev-1019-de35e6d`에 보존했다. 이후 별도 framework sync와 다른 active release가 생겨 표준 release tag finish만 fail-closed로 남았으며 live dev 배포·9개 경로 판정과 분리한다.
+- 세션 한정 override: tracked 설정은 변경하지 않고 live runtime config의 Gemini/GPT hybrid Work 바인딩 네 곳만 `ornith:35b`로 바꾸었다. 원본 백업, config check, refresh dry-run/apply 통과 근거를 확인했으며 세션 종료 시 원래 `ornith-fast`로 복구한다.

+- 입력:
+  - `normalization.tool_calls[operation].wire`: provider tool-call metadata normalization 선택자
+  - `tool_calls[].id` / `tool_call_id`: caller가 왕복 보존하는 표준 id 표면
+- 출력:
+  - Gemini signature가 있는 tool call은 signature를 별도 extension으로 노출하지 않고 opaque id를 반환한다.
+- 금지:
+  - caller/SDK 이름으로 분기하지 않는다.
+  - effort mapping을 tool-call metadata selector로 재사용하지 않는다.
+  - non-Gemini profile 응답을 변환하지 않는다.

+| S01 | `minimal-html-calls` | OpenCode가 Gemini direct route에서 tool을 호출한다 | tool result를 같은 Chat history로 재전송한다 | Edge가 signature를 복원하고 provider continuation이 성공한다. |
+| S02 | `failed-path-fixes` | Gemini와 non-Gemini protocol profile | 동일 signature 모양의 응답 및 malformed opaque id를 처리한다 | Gemini wire만 왕복하고 non-Gemini는 무변경, malformed는 fail-closed다. |
+| S03 | `thin-bench-handoff` | direct/hybrid를 포함한 9개 얇은 경로 결과 | 결과표를 갱신한다 | 호출 가능 여부와 남은 소유 경계만 남고 새 harness는 없다. |

-- 각 경로는 최초 1회만 실행하고 120초 안에 terminal을 확인한다. direct 경로는 caller workspace의 `index.html`, Edge-owned execution preset은 비공개 workspace 정리 계약 때문에 caller 로컬 파일이 아니라 caller-visible `decision.output`의 완료·marker를 판정한다.
-- 실패하면 자동 retry나 전체 재실행을 하지 않는다. sanitized terminal/error와 IOP request stage만 확인해 소유 경계를 정하고, 변경된 원인이 있을 때 실패 경로만 1회 재검증한다.
-- 제품 코드를 수정한 결함에는 해당 소유 package의 focused regression test를 추가하고 관련 Go test를 실행한다.

-- [ ] [minimal-html-calls] 9개 조합에 동일한 최소 HTML 구현 요청을 한 번씩 직접 실행하고, 경로별 caller/model/route, terminal, 경과 시간, marker 확인 결과를 한 개의 Markdown 표에 기록한다. direct는 caller workspace 파일, Edge-owned execution preset은 caller-visible terminal output을 확인한다. 사설 dev CA가 필요한 호출은 caller가 공식 지원하는 command-scoped CA 변수에 managed CA bundle을 전달한다. Codex는 `CODEX_CA_CERTIFICATE`, Node 기반 caller는 필요한 경우 `NODE_EXTRA_CA_CERTS`를 사용한다. 검증: 새 runner/manifest 없이 각 행에 실제 호출 결과가 하나만 있어야 하며, 호출 전후 ambient Codex/IDE/shell 환경에는 CA 변수가 없어야 한다.
-- [ ] [failed-path-fixes] 실패한 조합마다 제품·caller·provider·환경 중 소유 경계를 기록하고, IOP 제품 결함이 재현된 경우에만 국소 수정과 focused regression을 수행한 뒤 해당 조합만 다시 호출한다. 검증: 성공한 조합의 반복 실행이 없고, 재실행 행에는 변경된 원인과 연결된 수정·테스트 근거가 있어야 한다.
-- [ ] [thin-bench-handoff] 9개 조합의 통과 또는 구체적 외부 차단 상태를 짧게 정리해 `[bench-lite-01]` 실행 가능 여부를 남긴다. 검증: 비교 점수나 순위가 아니라 호출 가능 여부와 남은 소유자만 기록한다.

-- 계획 범위: 짧은 단일 test plan으로 즉시 실행할 수 있게 유지한다. 별도 설계·SDD·다단계 복구 계획으로 확장하지 않는다.
-- 실행 방식: 기존 공식 caller 명령을 한 번씩 직접 실행한다. 공통화가 필요해 보여도 이 Milestone에서는 script로 승격하지 않는다.
-- TLS 환경 경계: 개발 Edge용 사설 CA는 Edge leaf 인증서가 아니라 managed CA bundle을 해당 벤치 caller process에만 전달한다. Codex에는 공식 변수 `CODEX_CA_CERTIFICATE`, Node 기반 caller에는 필요한 경우 `NODE_EXTRA_CA_CERTS`를 사용하며 Codex/IDE 시작 환경이나 셸 전역에 `export`하지 않는다. 그렇지 않으면 공개 TLS 연결에도 같은 CA override가 적용될 수 있다.
-- evidence 위치: `agent-test/dev/iop-benchmark-route-minimal-html-smoke.md`
-- 현재 사전 확인: 2026-08-13 실제 원격 실행기에서 Claude Code 2.1.177, agy 1.1.12, Codex 0.146.0을 확인했고, 원격 SOPS에 보관된 기존 IOP principal token으로 token 원문을 출력하지 않은 `/v1/models`가 HTTP 200임을 확인했다. 새 벤치 전용 token은 발급하거나 사용하지 않는다.
-- 현재 경로 결과: Claude Code → Claude direct와 Claude Code → Gemini direct는 최소 HTML 1회 호출을 통과했다. Claude Code → GPT direct는 Chat Completions의 tools+reasoning 조합 미지원으로 실패했으나 caller-neutral operation normalization 반영 뒤 9초 안에 caller success와 `index.html` marker 1회를 확인했다. Codex → GPT direct와 Codex → GPT execution preset도 각각 10초/16초에 통과했다.
-- 추가 분리 결과: agy → Gemini direct는 누락된 caller `modelProvider=gemini`를 보정한 뒤 공식 URL-encoded model label을 IOP Gemini path parser가 거부하는 제품 결함까지 좁혔다. Codex → GPT direct의 최초 실패는 CA bundle 대신 Edge leaf 인증서를 전달한 측정 환경 결함이었다. Claude Code → Gemini/GPT preset은 모두 provider 호출 뒤 Plan `validation`으로 닫혔고, 원인은 `default` selector가 비워 둔 provider ID와 pool이 선택한 실제 provider ID를 사후에 무조건 비교한 IOP 결함으로 확인했다. explicit selector와 profile/model/credential/path fence는 유지하면서 default selector의 pool 선택만 인정하도록 수정했고, private Plan/Work/Review에도 profile별 Chat/Responses 선택과 nearest-lower effort mapping을 적용한 focused regression 및 Edge 전체 테스트가 통과했다. 개발 런타임에는 아직 배포되지 않았다.

+- 2026-08-14: Added operation-scoped `normalization.tool_calls` and Gemini-only Chat thought-signature round trips across standard OpenAI-compatible callers, including non-stream, SSE, and recovery-selected dispatches. Effort mapping and caller identity remain independent (`packages/go/config/protocol_profile.go`, `apps/edge/internal/openai/provider_model_rewrite.go`).
 - 2026-08-13: Added official agy 1.1.12 model-role `functionResponse` continuation support while retaining fail-closed rejection for mixed assistant/tool-response content (`apps/edge/internal/openai/gemini_handler.go`).
 - 2026-08-12: Admitted Claude Code's `advisor-tool-2026-03-01` beta as a consumed compatibility marker for both direct and marked-preset Messages ingress. It grants no internal capability and is not forwarded through the Chat bridge (`apps/edge/internal/openai/anthropic_types.go`).
 - 2026-08-12: Replaced free-form PlanMD generation with a stage-owned strict `goal`/`steps`/`verification` JSON response and deterministic Edge rendering of the frozen Plan template. Internal artifact customization and all caller-visible Messages schemas remain unchanged (`apps/edge/internal/openai/single_request_plan_stage.go`, `packages/go/singlerequesttemplate/template.go`).

 - 2026-08-09: Extended `output_config.effort` to accept `low`, `medium`, `high`, `xhigh`, and `max` across Anthropic native and Chat bridge routes without substitution or normalization. Unknown effort values remain `400 invalid_request_error` before provider dispatch. Deterministic Go coverage added for exact bridge mapping, native `max` preservation, and invalid-value rejection. (`apps/edge/internal/openai/anthropic_types.go`, `apps/edge/internal/openai/anthropic_bridge_test.go`, `apps/edge/internal/openai/anthropic_native_test.go`)
 - 2026-08-13: Added caller-neutral provider operation normalization for Messages/Responses routes. Tool-bearing adaptive effort can select Responses when Chat cannot preserve the combination, and unsupported effort grades fall only to the nearest declared lower grade (for example `max` to `xhigh`).
 - 2026-08-14: Normalized Anthropic mid-conversation `system` messages across strict ingress, logical-request lineage, Chat, and Responses provider wires. Ordered system authority is preserved; first-position, invalid-placement, non-text, and pending-tool interruption shapes remain fail-closed.
+- 2026-08-14: `/v1/responses` provider-pool bridge now selects native Responses, Anthropic Messages, or OpenAI Chat by protocol profile. Messages/Chat responses are rendered back to canonical Responses; unrepresentable controls fail closed and Gemini thought-signature tool continuations retain opaque `call_id` replay.
 - 2026-08-14: Applied the same provider-normalization boundary to private single-request Plan/Work/Review stages. Removed pre-selection Chat operation pinning, added Chat↔Responses stage conversion and nearest-lower effort mapping, and corrected default-selector dispatch validation so the pool-selected provider is accepted without weakening explicit provider, profile, credential, target, or execution-path fences.
 - 2026-08-14: Canonicalized private Chat Completions stage responses before strict Plan/Work/Review decoding. Standard OpenAI bookkeeping fields are stripped centrally, a non-null refusal remains fail-closed, and Responses/Chat now converge on the same private envelope instead of making stage codecs provider-specific.
 - 2026-08-14: Added provider `timings` to the bounded Chat response bookkeeping stripped before private stage decoding, aligning the common normalizer with the existing Ornith Work codec without admitting unknown response fields.

+
+## Key Design Decisions
+
+- Messages `content_block_start`의 `tool_use.input`이 `{}`여도 tool fragment를 생성한다. 후속 `input_json_delta`가 있는 호출의 기존 fragment 조립 경로는 유지한다.
+- handler/runtime regression fixture는 argument delta 없이 종료되는 `call-zero`/`ping` 호출을 사용하고, canonical argument completion, id/name/`{}` 보존, usage 및 단일 terminal/DONE을 함께 확인한다.
+
+## Reviewer Checkpoints
+
+- `{}` at Anthropic `content_block_start` produces one tool fragment with the original id/name.
+- Non-empty fragmented tool arguments remain correctly assembled without duplication.
+- Handler/runtime output contains one canonical completed `function_call`, one `response.completed`, and one `[DONE]`.
+- Existing usage preservation, error sanitation, native Responses passthrough, and caller-neutral selection remain green.

+## Code Review Result
+
+- Overall Verdict: `FAIL`
+- Dimension Assessment:
+  - Correctness: Fail — fragmented Anthropic tool arguments are prefixed with the start-frame `{}` placeholder.
+  - Completeness: Fail — the plan required preserving existing non-empty fragmented argument assembly, but that path regressed.
+  - Test coverage: Fail — the Messages `fragmented` case covers text only and does not exercise `tool_use` plus `input_json_delta`.
+  - API contract: Fail — canonical Responses emits invalid concatenated function-call arguments for a valid Anthropic stream.
+  - Code quality: Pass.
+  - Implementation deviation: Fail — REVIEW_REVIEW_API-1 did not retain the plan's fragmented-delta invariant.
+  - Verification trust: Fail — the recorded commands pass but the claimed preservation is contradicted by a fresh focused reproducer.
+- Findings:
+  - Required R6 — preserve zero-argument calls without prefixing ordinary fragmented tool arguments.
+    - Evidence: `stream_gate_tunnel_codec.go:471-477` emits `{}` at every `tool_use` start, while `stream_gate_tunnel_codec.go:494-507` also emits each later `input_json_delta`; `openAIResponsesPoolReleaseSink.Release` appends both fragments. A fresh temporary package test using `input:{}` followed by `partial_json:"{\"q\":\"x\"}"` failed with `assembled arguments="{}{\"q\":\"x\"}"`, want `"{\"q\":\"x\"}"`. The temporary test file was removed after the run.
+    - Root Cause: the decoder treats Anthropic's ambiguous start-frame `{}` as completed arguments before it knows whether later argument deltas exist. The sink has no replacement semantics, so it correctly concatenates the placeholder and real fragments.
+    - Selected Fix: in `stream_gate_tunnel_codec.go`, track pending empty-object tool starts by block index, do not emit `{}` immediately, discard the pending placeholder when the first `input_json_delta` arrives, and emit one `{}` fragment at `content_block_stop` (or terminal fallback) only if no argument delta arrived. In `stream_gate_pipeline_test.go`, add both codec and handler/runtime cases: zero-delta calls remain exactly `{}`, while start `{}` plus fragmented deltas assembles exactly the delta JSON with one canonical completed function call and one terminal/`[DONE]`.
+- Routing Signals:
+  - `review_rework_count=3`
+  - `evidence_integrity_failure=true`
+- Next Step: Archive this pair and execute the code-review follow-up plan for R6 after fresh isolated routing.

+
+## Archive Evidence Snapshot
+
+- 이전 계획: `agent-task/responses_provider_bridge/plan_cloud_G05_2.log`
+- 이전 리뷰: `agent-task/responses_provider_bridge/code_review_cloud_G05_2.log`
+- 판정: `FAIL`; Required R6 1건, Suggested/Nit 없음.
+- 리뷰어 재현: `input:{}` 뒤 `partial_json:"{\"q\":\"x\"}"`가 `{}{\"q\":\"x\"}`로 조립됐다. 기존 focused/package/race/diff 명령은 통과했지만 이 변형을 검사하지 않았다.
+
+## For the Review Agent
+
+Compare implementation with the Finding Resolution Map in `PLAN-cloud-G05.md`, run every applicable command fresh, append one verdict, then finalize according to the code-review skill.
+
+## Implementation Item Completion
+
+| Item | Status |
+|---|---|
+| REVIEW_REVIEW_REVIEW_API-1 Deferred empty-object completion | [x] |
+| REVIEW_REVIEW_REVIEW_API-2 Dual lifecycle regression | [x] |
+
+## Implementation Checklist
+
+- [x] Implement REVIEW_REVIEW_REVIEW_API-1 deferred empty-object Messages tool-call completion.
+- [x] Implement REVIEW_REVIEW_REVIEW_API-2 zero-delta and fragmented public Responses regressions.
+- [x] Run focused inventory/package/race/diff verification.
+- [x] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.
+
+## Review-Only Checklist
+
+> Review agent only. Implementing agents must not modify this section.
+
+- [x] Append one PASS/WARN/FAIL verdict and verified routing signals.
+- [x] Verify dimensions and finding classifications match.
+- [x] Run and record applicable fresh verification.
+- [x] Close evidence/root cause/selected fix for any finding.
+- [x] Archive this review to `code_review_cloud_G05_3.log` and plan to `plan_cloud_G05_3.log`.
+- [x] Verify Agent-Ops `.gitignore` block.
+- [x] On PASS, write `complete.log` and move the task to `agent-task/archive/YYYY/MM/responses_provider_bridge/`.
+- [ ] On WARN/FAIL, materialize the required next state and do not write `complete.log`.
+
+## Deviations from Plan
+
+없음.
+
+## Key Design Decisions
+
+`tool_use input:{}`는 block index별 `pendingEmpty`로만 기록한다. 첫
+`input_json_delta`는 pending 상태를 폐기한 뒤 delta만 emit한다. block stop은
+여전히 pending인 도구에만 `{}`를 한 번 emit하며, block stop이 누락된 provider
+stream은 terminal 직전 fallback flush로 동일하게 처리한다. pending flag를
+emit 직전에 해제하므로 stop과 terminal fallback은 중복 completion을 만들지
+않는다.
+
+## Reviewer Checkpoints
+
+- Zero-delta `input:{}` emits exactly one `{}` completed call.
+- `input:{}` followed by argument deltas assembles only the deltas, never a `{}` prefix.
+- Block-stop and terminal fallback cannot duplicate a tool call.
+- Both variants preserve id/name/usage and emit one function-call completion, one `response.completed`, and one `[DONE]`.

+## Code Review Result
+
+- Overall Verdict: `PASS`
+- Dimension Assessment:
+  - Correctness: Pass — deferred `{}` is discarded on the first argument delta and emitted only by the first stop/terminal fallback path when no delta exists.
+  - Completeness: Pass — both R6 implementation items and their public Responses lifecycle checks are present.
+  - Test coverage: Pass — codec fragmentation, zero-delta fallback, exact arguments, identity, usage, function-call completion, response terminal, and `[DONE]` are covered.
+  - API contract: Pass — canonical Responses SSE output is preserved for Anthropic Messages provider wire without changing request admission or public schema.
+  - Code quality: Pass — the state transition is request-local, deterministic for multiple pending indices, and contains no debug or unrelated cleanup.
+  - Implementation deviation: Pass — no deviation from the selected R6 fix or modified-file scope was found.
+  - Verification trust: Pass — fresh reviewer commands reproduced the recorded successful inventory, focused, package, race, and diff results.
+- Findings: None.
+- Routing Signals: `review_rework_count=3`, `evidence_integrity_failure=false`
+- Next Step: Archive this PASS pair, write `complete.log`, and move the task to the monthly task archive.

+
+## For the Review Agent
+
+> **[REVIEW AGENT ONLY]** Compare every item with source and run fresh verification. Implementation output is handoff evidence only. Append verdict and routing signals, archive the active pair, and create `complete.log`/archive the task directory only on PASS. WARN/FAIL must follow the code-review skill and include reviewer-proven root cause plus one selected fix.
+
+## Implementation Item Completion
+
+| Item | Status |
+|---|---|
+| API-1 Profile-selected Responses request bridge | [x] |
+| API-2 Convert provider responses and streams to Responses | [x] |
+| API-3 Lock compatibility with tests and contracts | [x] |
+
+## Implementation Checklist
+
+- [x] Implement API-1 profile-selected Responses request bridging and fail-closed admission without caller-specific branches.
+- [x] Implement API-2 provider response/stream conversion back to canonical Responses while preserving tools, reasoning, usage, errors, and exactly-one terminal.
+- [x] Implement API-3 focused regression coverage and synchronize the OpenAI outer contract and living spec.
+- [x] Run local focused/package verification; external cycles are blocked pending the plan-required approved `origin/dev` implementation commit and clean exact-source redeploy.
+- [x] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.
+
+## Review-Only Checklist
+
+> **[REVIEW AGENT ONLY]** Implementing agents must not modify or check this section.
+
+- [x] Append one verdict of `PASS`, `WARN`, or `FAIL` and verified `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
+- [x] Verify verdict, dimensions, and Required/Suggested/Nit classifications match.
+- [x] Run applicable required verification and record fresh output.
+- [x] For each Required/Suggested finding, record evidence, root cause, one selected fix, files/symbols/tests, and acceptance commands.
+- [x] Archive active review to `code_review_cloud_G08_0.log` and plan to `plan_local_G08_0.log`.
+- [x] Verify the Agent-Ops managed `.gitignore` block.
+- [ ] On PASS, write `complete.log`, remove active markdown files, and move the task directory to `agent-task/archive/YYYY/MM/responses_provider_bridge/`.
+- [x] On WARN/FAIL, write the next filesystem state required by the code-review skill and do not write `complete.log`.
+
+## Deviations from Plan
+
+External dev deployment/Codex cycles were not run. The plan requires an approved implementation commit on `origin/dev` and a clean exact-SHA runner rebuild/redeploy before those cycles; this worker must not commit/push or start deployment orchestration. Local bridge and package/race verification was completed.
+
+## Key Design Decisions
+
+- `selectProviderOperation` chooses native Responses for profiles that expose it, otherwise Anthropic Messages or OpenAI Chat from the profile driver and capability set. No caller/SDK identity participates.
+- `PrepareProtocolTunnel` changes operation/path/body only after candidate selection. Native Responses and nil-profile legacy paths keep their existing raw tunnel behavior.
+- Responses→Messages/Chat conversion rejects controls or input items that cannot be represented. Gemini tool thought signatures continue through the existing opaque call-id envelope.
+- StreamGate remains the terminal owner. Messages and Chat tunnel frames are decoded into normalized text/reasoning/tool events and rendered as canonical Responses for bridge attempts.
+
+## Reviewer Checkpoints
+
+- Native Responses profile and nil-profile fallback remain byte-compatible.
+- Selection is based only on request requirements and concrete protocol profile, never caller/agent identity.
+- Unsupported Responses controls fail before provider dispatch rather than being dropped.
+- Claude uses Messages wire and Gemini uses Chat wire; both return canonical Responses JSON/SSE.
+- Gemini thought signature survives function call → `call_id` → function result replay.
+- StreamGate remains the single response/terminal owner, including recovery attempts.
+- Contract/spec match code and keep normalized non-provider limitations unchanged.

+## Code Review Result
+
+- Overall Verdict: `FAIL`
+- Dimension Assessment:
+  - Correctness: Fail
+  - Completeness: Fail
+  - Test coverage: Fail
+  - API contract: Fail
+  - Code quality: Pass
+  - Implementation deviation: Fail
+  - Verification trust: Fail
+- Findings:
+  - Required R1 — Messages bridge admission accepts a request whose provider body cannot be built.
+    - Evidence: `prepareResponsesMessagesBridge` requires `max_output_tokens` at `apps/edge/internal/openai/provider_normalization.go:535-538`, but `TestResponsesProtocolProfileBridgesToAnthropicMessages` sends none at `apps/edge/internal/openai/responses_protocol_profile_test.go:457`. The fake provider-pool path suppresses `BuildBody` errors in `apps/edge/internal/openai/provider_test_support_test.go:351-359`, so the test returns 200 although the real provider-pool builder propagates the error.
+    - Root Cause: candidate admission and pre-dispatch validation do not prove that the selected Messages wire has an effective positive `max_tokens`, and the happy-path regression test neither supplies nor asserts the planned max-token mapping.
+    - Selected Fix: in `responses_handler.go`/`provider_normalization.go`, resolve the catalog output-token policy before Messages body construction; map a positive effective value to `max_tokens`, and reject the request as `400 invalid_request_error` before tunnel dispatch when neither caller nor catalog provides one. Update `responses_protocol_profile_test.go` to assert the built Messages body and add the no-effective-limit fail-closed case. Acceptance: the focused profile tests pass and the no-limit case records zero tunnel requests.
+  - Required R2 — Anthropic Messages usage is lost from the canonical Responses result.
+    - Evidence: `decodeMessagesTunnelFrame` parses content only at `apps/edge/internal/openai/stream_gate_tunnel_codec.go:367-510`; `providerChatAssembler.consumeSSELine` understands only OpenAI `usage` and nested Responses usage at `apps/edge/internal/openai/provider_observation.go:152-189`. Consequently Anthropic `message_start.usage.input_tokens` and `message_delta.usage.output_tokens` never reach the usage holder, and the terminal Responses object renders zeros.
+    - Root Cause: the new Messages wire discriminator was added to the semantic codec but not to the usage observer that owns provider-reported token accounting.
+    - Selected Fix: make the tunnel usage observer operation/wire-aware, parse Anthropic non-stream and streaming usage into the existing `usageObservation`, bind the selected provider wire for every initial/recovery attempt, and add handler-level assertions that canonical Responses usage preserves input/output/total counts. Acceptance: focused streaming/non-stream bridge tests and the full package/race commands pass.
+  - Required R3 — streaming bridge provider errors can expose provider-native bodies.
+    - Evidence: `openAIResponsesPoolReleaseSink.CommitTerminal` calls `commitProviderErrorLocked` whenever a codec error response exists and headers are not committed; that helper copies provider headers/status/body directly. It does not check whether the selected codec is native Responses or a Messages/Chat bridge. The planned `TestResponsesProviderBridgeProviderErrorSanitized` does not exist.
+    - Root Cause: raw-error relay remained transport-oriented after the success path became public-wire aware.
+    - Selected Fix: retain raw error relay only for native Responses passthrough; for Messages/Chat bridge attempts render the existing sanitized canonical Responses error terminal with exactly one `[DONE]`, without provider body/header leakage. Add the exact provider-error regression test through the handler/pool sink. Acceptance: the named error test proves one sanitized terminal and absence of provider-native secret text.
+  - Required R4 — required response/lifecycle regressions were not implemented and the verification regex hid their absence.
+    - Evidence: `go test -list` returned only `TestResponsesProviderBridgeStreaming`; `TestResponsesProtocolProfileAnthropicBridgeResponse`, `TestResponsesProtocolProfileGeminiBridgeResponseAndSignature`, `TestResponsesProviderBridgeStreamingTerminalExactlyOnce`, and `TestResponsesProviderBridgeProviderErrorSanitized` are absent. The existing codec-only test at `stream_gate_pipeline_test.go:161-200` does not exercise canonical JSON/SSE rendering, usage, error sanitation, or terminal ownership.
+    - Root Cause: broad alternation-based `-run` commands were treated as proof without verifying the named test inventory, and handler-level acceptance assertions were replaced by one codec aggregation test.
+    - Selected Fix: add all four exact tests with handler/runtime fixtures, including canonical output items, Gemini call-id replay, usage, provider-native framing exclusion, one response terminal, and one `[DONE]`; add deterministic `go test -list` verification before the focused run. Acceptance: all five exact names are listed and run, then package/race/diff verification passes.

+
+## Deviations from Plan
+
+None.
+
+## Key Design Decisions
+
+- Responses provider-pool ingress freezes the existing model catalog output-token policy into a bridge-only request body. Messages admission validates that the resulting `max_output_tokens` is a positive integer before a tunnel request can be recorded or sent.
+- `providerChatAssembler` remains the single usage observation owner and is bound to the selected provider wire. Anthropic `message_start.message.usage`, `message_delta.usage`, and non-stream `usage` merge into the existing holder used by canonical Responses rendering and attempt metrics.
+- The Responses pool sink binds each attempt's provider wire. Only native Responses streaming can relay a raw provider error; Messages/Chat bridge failures emit one sanitized Responses `error` event and one `[DONE]`.
+
+## Reviewer Checkpoints
+
+- R1: Messages wire always gets a positive effective `max_tokens` or rejects before dispatch.
+- R2: Anthropic stream/non-stream usage reaches canonical Responses usage and existing metrics owner.
+- R3: bridge provider error leaks no provider-native body/header and owns one terminal/`[DONE]`.
+- R4: all five exact tests exist and exercise handler/runtime public output.
+- Native Responses passthrough and caller-neutral profile selection remain unchanged.

+
+## Code Review Result
+
+- Overall Verdict: FAIL
+- Dimension Assessment:
+  - Correctness: Fail — Anthropic streaming `tool_use` with valid empty-object arguments is omitted from canonical Responses output.
+  - Completeness: Fail — R4's required function-call/public-output bridge coverage does not include this valid Messages lifecycle variant.
+  - Test coverage: Fail — the exact Messages streaming test is codec-level text-only and cannot detect the dropped public function call.
+  - API contract: Fail — the bridge contract promises function call/result preservation when representable.
+  - Code quality: Pass
+  - Implementation deviation: Fail — the R4 selected fix required handler/runtime public-output coverage for the bridge inventory.
+  - Verification trust: Fail — the recorded claim that all five exact tests exercise handler/runtime public output is contradicted by the fresh source/test inspection.
+- Findings:
+  - Required R5 — Preserve zero-argument Anthropic streaming tool calls in canonical Responses output.
+    - Evidence: `nl -ba apps/edge/internal/openai/stream_gate_tunnel_codec.go | sed -n '420,490p'` shows the streaming `content_block_start` branch at line 471 explicitly rejects `input:{}`; `nl -ba apps/edge/internal/openai/stream_gate_pipeline_test.go | sed -n '155,260p'` shows the exact Messages streaming test covers text only. Existing repository fixtures such as `hot_path_anthropic_gate_test.go` establish `input:{}` as a valid provider tool-call shape.
+    - Root Cause: `decodeMessagesTunnelFrame` treats `{}` as a placeholder that must wait for `input_json_delta`, but a zero-argument Anthropic tool call may terminate without any delta. Because no `ToolCallFragment` is emitted, `openAIResponsesPoolReleaseSink` never opens or completes a canonical `function_call` item.
+    - Selected Fix: In `apps/edge/internal/openai/stream_gate_tunnel_codec.go`, emit the tool identity and `{}` arguments for `content_block_start` even when the input object is empty, while retaining fragmented non-empty argument assembly. Extend `TestResponsesProviderBridgeStreaming` in `apps/edge/internal/openai/stream_gate_pipeline_test.go` through the handler/runtime path to assert one canonical `function_call` with the original id/name and `arguments:"{}"`, one `response.completed`, and one `[DONE]`.
+- Routing Signals: `review_rework_count=2`, `evidence_integrity_failure=true`
+- Next Step: Create and execute a routed WARN/FAIL follow-up plan for Required R5; do not write `complete.log`.

+# Zero-Argument Anthropic Tool Call Review Fix Plan
+
+## For the Implementing Agent
+
+Required R5의 선택된 수정만 구현한다. 원인을 재조사하거나 다른 해결책을 선택하지 않는다. 검증 명령을 실제 실행하고 결과 원문을 `CODE_REVIEW-cloud-G05.md`의 구현 담당 섹션에 기록한 뒤 active 파일을 그대로 둔다. 사용자 질문, archive, `complete.log` 작성은 하지 않는다.
+
+## Background
+
+두 번째 리뷰에서 Anthropic Messages streaming `tool_use`의 `input:{}`가 canonical Responses `function_call`로 복원되지 않는 결함이 확인됐다. 이 follow-up은 zero-argument tool call identity와 empty-object arguments를 public Responses lifecycle에 보존한다.
+
+## Archive Evidence Snapshot
+
+- 이전 계획: `agent-task/responses_provider_bridge/plan_cloud_G08_1.log`
+- 이전 리뷰: `agent-task/responses_provider_bridge/code_review_cloud_G08_1.log`
+- 판정: `FAIL`; Required R5 1건, Suggested/Nit 없음.
+- 리뷰어 검증: focused/package/race/diff는 통과했으나 `stream_gate_tunnel_codec.go:471`가 `input:{}`를 명시적으로 제외하고, Messages streaming test는 text-only라 public function call 누락을 검출하지 못했다.
+

+|---|---|---|---|---|---|---|
+| R5 | `decodeMessagesTunnelFrame`의 `content_block_start`가 `input:{}`를 제외하며 handler/runtime Messages fixture가 tool call을 포함하지 않음 | empty object를 무조건 후속 `input_json_delta` 대기 placeholder로 취급해 zero-argument call의 fragment가 한 번도 생성되지 않음 | start frame에서 tool identity와 `{}` argument fragment를 emit하고, handler/runtime streaming test에서 canonical function call과 exactly-one terminal을 검증 | direct-fix | valid zero-argument Messages tool call이 normalized fragment 및 Responses sink에 도달 | focused regression, package, race, diff |

+
+### SDD Criteria
+
+해당 없음. 비-Milestone API 호환성 결함의 좁은 follow-up이다.
+
+### Verification Context
+
+- local worktree에서 Go test를 fresh 실행한다.
+- review evidence가 exact branch와 test gap을 확정했으므로 추가 진단이나 외부 runner가 필요하지 않다.
+- 외부 dev cycle은 승인 commit/push 및 exact-source redeploy 이후 범위이며 R5 구현 검증의 선행 조건이 아니다.
+
+### Test Coverage Gap
+
+`TestResponsesProviderBridgeStreaming`의 Messages case는 codec text만 검사하고, handler/runtime public output의 zero-argument `function_call`을 검사하지 않는다.
+
+### Symbol References
+
+공개 symbol rename/remove 없음. `decodeMessagesTunnelFrame` 내부 branch와 기존 test fixture만 변경한다.
+
+### Split Judgment
+
+단일 plan이다. decoder fragment 생성과 public Responses lifecycle 회귀 검증은 하나의 결함 수정이며 독립 배포 가능한 중간 계약이 없다.
+
+### Scope Rationale
+
+profile schema, request admission, usage/error policy, contract/spec, Node wire, roadmap은 변경하지 않는다. 기존 non-empty fragmented argument 조립을 유지한다.
+
+### Final Routing
+
+- evaluation_mode: `isolated-reassessment`
+- finalizer: `finalize-task-policy.sh`, mode `pair`
+- closures: build/review 모두 scope, context, verification, evidence, ownership, decision closed
+- build/review scores: scope=1, state=1, blast=2, evidence=0, verification=1; grade `G05`

+- positive loop risks: `boundary_contract`, `structured_interpretation` (2)
+- canonical files: `PLAN-cloud-G05.md`, `CODE_REVIEW-cloud-G05.md`
+
+## Implementation Checklist
+
+- [ ] Implement REVIEW_REVIEW_API-1 zero-argument Messages tool-call preservation.
+- [ ] Implement REVIEW_REVIEW_API-2 handler/runtime public Responses regression coverage.
+- [ ] Run focused/package/race/diff verification.
+- [ ] Fill implementation-owned sections in `CODE_REVIEW-*-G??.md` with actual implementation notes and verification output.
+
+### [REVIEW_REVIEW_API-1] Preserve empty-object Messages tool calls
+
+#### Problem
+
+`apps/edge/internal/openai/stream_gate_tunnel_codec.go:471` emits a `ToolCallFragment` only when `content_block_start.input` is not `{}`. A valid zero-argument Anthropic tool call can end without `input_json_delta`, so its id, name, and arguments are lost.
+
+#### Solution
+
+Emit the tool identity and the valid JSON object from `content_block_start` even when it is `{}`. Preserve the existing delta path for calls whose arguments arrive as `input_json_delta`; do not emit duplicate argument content for non-empty starts.
+
+```go
+// before: empty-object calls are discarded
+if payload.ContentBlock.Type == "tool_use" && len(payload.ContentBlock.Input) > 0 && string(payload.ContentBlock.Input) != "{}" {
+
+// after: every valid start input, including {}, creates the initial fragment
+if payload.ContentBlock.Type == "tool_use" && len(payload.ContentBlock.Input) > 0 {
+```
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: include `{}` in the start-frame tool fragment path while retaining id/name defaults and fragmented delta assembly.
+
+#### Test Strategy
+
+Regression test is mandatory. The existing handler/runtime test will prove the public lifecycle, so no new test file is needed.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run '^TestResponsesProviderBridgeStreaming(TerminalExactlyOnce)?$'
+```
+
+Expected: zero-argument tool fixture and existing streaming variants pass.
+
+### [REVIEW_REVIEW_API-2] Lock the public Responses lifecycle
+
+#### Problem
+
+`apps/edge/internal/openai/stream_gate_pipeline_test.go:162-209` checks codec-level Messages text only, while the handler/runtime fixture at lines 211-236 has no tool event. Neither assertion detects a dropped canonical function call.
+
+#### Solution
+
+Extend the Messages handler/runtime frames with one `content_block_start` tool call whose `input` is `{}` and no argument delta follows. Assert the response contains exactly one completed `function_call` with original id/name and `arguments:"{}"`, exactly one `response.completed`, and exactly one `[DONE]`. Keep existing usage assertions.
+
+```go
+// fixture addition
+data: {"type":"content_block_start","index":1,"content_block":{"type":"tool_use","id":"call-zero","name":"ping","input":{}}}
+
+// public-output assertions
+strings.Count(body, `"type":"function_call"`) == 1
+strings.Contains(body, `"call_id":"call-zero"`)
+strings.Contains(body, `"arguments":"{}"`)
+```
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: add the zero-argument Messages fixture and canonical output/terminal assertions.
+
+#### Test Strategy
+
+Use the existing `TestResponsesProviderBridgeStreamingTerminalExactlyOnce` handler/runtime path. The test must fail against the current source and pass after REVIEW_REVIEW_API-1.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run '^TestResponsesProviderBridgeStreamingTerminalExactlyOnce$'
+```
+
+Expected: one canonical function call with preserved identity/empty arguments and one terminal/`[DONE]`.

+# Anthropic Fragmented Tool Argument Preservation Plan
+
+## For the Implementing Agent
+
+Required R6의 선택된 수정만 구현한다. 원인을 재조사하거나 다른 해결책을 선택하지 않는다. 검증 명령을 실제 실행하고 결과 원문을 `CODE_REVIEW-cloud-G05.md`의 구현 담당 섹션에 기록한 뒤 active 파일을 그대로 둔다. 사용자 질문, archive, `complete.log` 작성은 하지 않는다.
+
+## Background
+
+zero-argument `tool_use` 보존 수정이 Anthropic의 일반 fragmented argument 호출을 `{}<delta>`로 조립하는 회귀를 만들었다. 이 follow-up은 start-frame `{}`를 delta 존재 여부가 확정될 때까지 보류해 zero-argument와 fragmented 호출을 모두 보존한다.

+단일 plan이다. pending placeholder 상태 전이와 두 상호 배타적 종료 변형은 하나의 조립 불변조건이며 분리하면 독립 PASS 계약이 없다.
+
+### Scope Rationale
+
+Responses sink의 append 계약, profile schema, request admission, usage/error policy, contract/spec, Node wire는 변경하지 않는다. decoder가 올바른 fragment sequence를 제공하는 선에서 닫는다.
+
+### Final Routing

+
+### [REVIEW_REVIEW_REVIEW_API-1] Defer ambiguous empty-object completion
+
+#### Problem
+
+`apps/edge/internal/openai/stream_gate_tunnel_codec.go:471-507` emits both start `{}` and later `input_json_delta`. `apps/edge/internal/openai/responses_stream_gate.go:1023-1040` appends fragments, yielding invalid concatenated JSON.
+
+#### Solution
+
+Extend the Messages codec's per-index tool state with pending-empty and argument-delta state. A `tool_use` start with non-empty input other than `{}` emits immediately. A `{}` start records pending state only. The first `input_json_delta` clears pending state before emitting the delta. `content_block_stop` emits `{}` only for a still-pending zero-delta tool. Terminal handling must flush any valid still-pending tool once if a provider omits block stop, without duplicating a prior stop flush.
+
+```go
+// before: ambiguous empty input is emitted immediately
+if payload.ContentBlock.Type == "tool_use" && len(payload.ContentBlock.Input) > 0 {
+    events = append(events, newTool(..., string(payload.ContentBlock.Input)))
+}
+
+// after: defer only the ambiguous empty-object placeholder
+if args == "{}" {
+    state.pendingEmpty = true
+} else {
+    events = append(events, newTool(..., args))
+}
+```
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: implement per-index pending empty-tool completion and exactly-once stop/terminal flush.
+
+#### Test Strategy
+
+Regression tests are mandatory in the existing pipeline test. Preserve a non-empty start input if present and verify start `{}` plus deltas never retains the placeholder.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run '^TestResponsesProviderBridgeStreaming(TerminalExactlyOnce)?$'
+```
+
+Expected: both zero-delta and fragmented tool calls pass.
+
+### [REVIEW_REVIEW_REVIEW_API-2] Lock both public lifecycle variants
+
+#### Problem
+
+`apps/edge/internal/openai/stream_gate_pipeline_test.go:162-248` covers Messages text fragmentation and a zero-delta tool call separately, but not a `tool_use input:{}` followed by `input_json_delta` through the handler/runtime Responses renderer.
+
+#### Solution
+
+Add a Messages codec case whose tool start is `{}` and whose argument JSON arrives in at least two deltas; assert assembled arguments equal only the delta JSON. Add or table-drive handler/runtime fixtures for zero-delta and fragmented calls, asserting original id/name, exact completed arguments, one `response.function_call_arguments.done`, one `response.completed`, one `[DONE]`, and preserved usage.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: add exact codec and public Responses lifecycle assertions for both variants.
+
+#### Test Strategy
+
+Use deterministic in-memory provider tunnel frames. The fragmented case must fail against `plan_cloud_G05_2.log` source behavior and pass only after REVIEW_REVIEW_REVIEW_API-1.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -list '^TestResponsesProviderBridgeStreaming(TerminalExactlyOnce)?$'
+go test -count=1 ./apps/edge/internal/openai -run '^TestResponsesProviderBridgeStreaming(TerminalExactlyOnce)?$'
+```
+
+Expected: both exact test names are listed and all variants pass.

+# Responses Provider Bridge Review Fix Plan
+
+## For the Implementing Agent
+
+아래 R1–R4의 선택된 수정만 구현한다. 검증 명령을 실제 실행하고 결과 원문을 `CODE_REVIEW-cloud-G08.md`의 구현 담당 섹션에 기록한 뒤 active 파일을 그대로 둔다. 원인 재조사, 대안 선택, 범위 변경, 사용자 질문, archive/`complete.log` 작성은 하지 않는다. 막히면 정확한 blocker와 시도 결과, 재개 조건만 기록한다.
+
+## Background
+
+첫 구현은 기본 패키지 테스트를 통과했지만 Messages 요청의 필수 token limit, Anthropic usage, bridge error sanitation, lifecycle 회귀 테스트가 닫히지 않았다. 이 follow-up은 리뷰에서 확정한 네 결함을 같은 provider-wire/public-Responses 경계 안에서 수정한다.
+
+## Archive Evidence Snapshot
+
+- 이전 계획: `agent-task/responses_provider_bridge/plan_local_G08_0.log`
+- 이전 리뷰: `agent-task/responses_provider_bridge/code_review_cloud_G08_0.log`
+- 판정: `FAIL`; Required R1–R4, Suggested/Nit 없음.
+- 리뷰어 검증: focused/package/race/diff는 통과했지만 `go test -list`에서 계획된 다섯 response/lifecycle 테스트 중 하나만 존재했다.
+- 외부 dev cycle은 고친 source의 승인 commit/push 및 exact-source redeploy 뒤에 수행한다.
+
+## Finding Resolution Map
+
+| ID | Reviewer evidence | Root cause | Selected fix | Mode | Changed precondition | Acceptance |
+|---|---|---|---|---|---|---|
+| R1 | Messages builder가 `max_output_tokens` 누락을 거부하지만 happy-path test는 값을 보내지 않고 fake가 BuildBody error를 무시함 | candidate admission과 request policy가 effective Messages `max_tokens`를 보장하지 않음 | catalog output-token policy를 bridge 전 적용하고 positive `max_tokens`를 생성하거나 dispatch 전 400으로 거부; body/fail-closed test 추가 | direct-fix | 실제 body build 성공 또는 명시적 pre-dispatch rejection | exact profile tests + zero-dispatch assertion |
+| R2 | Messages codec/assembler가 Anthropic `message_start`/`message_delta` usage를 읽지 않아 terminal usage가 0 | provider wire를 semantic decoder에만 전달하고 usage observer에는 전달하지 않음 | usage observer를 wire-aware로 만들고 Anthropic stream/non-stream usage를 `usageObservation`에 누적; canonical usage assertion 추가 | direct-fix | Anthropic usage가 existing holder/sink에 도달 | exact bridge tests + package/race |
+| R3 | pool sink가 bridge codec에서도 provider error body/header를 raw relay함 | raw error policy가 public wire 선택과 분리됨 | native Responses에서만 raw relay, Messages/Chat은 sanitized Responses error + `[DONE]` 1회 | direct-fix | error terminal도 public Responses wire를 따름 | exact sanitized-error test |
+| R4 | `go test -list` 결과 exact five 중 codec test 하나만 존재 | regex 성공을 test inventory 증거로 오판하고 handler lifecycle coverage를 생략 | 누락된 exact four tests를 handler/runtime 수준으로 추가하고 inventory check를 verification 앞에 둠 | direct-fix | named acceptance tests가 실제 존재하고 public output을 검증 | list count/name + focused/full/race/diff |

+
+### Verification Context
+
+- 현재 local worktree와 Go test를 사용하며 cache를 금지한다.
+- reviewer fresh package/race/diff는 통과했으나 exact test inventory와 source inspection이 R1–R4를 증명했다.
+- external runner는 `ssh toki@toki-labs.com`, workdir `/Users/toki/agent-work/iop-dev`, branch `dev`다. 승인 implementation SHA가 `origin/dev`에 있고 runner가 clean exact SHA로 rebuild/redeploy된 뒤에만 Claude/Gemini Codex cycle을 실행한다. 이 follow-up worker는 commit/push/deploy를 수행하지 않는다.
+
+### Test Coverage Gaps
+
+- Messages effective max token: happy/fail-closed body assertion 없음.
+- Anthropic usage: streaming/non-stream canonical Responses assertion 없음.
+- bridge provider error: sanitized public terminal assertion 없음.
+- exactly-one terminal: handler/runtime bridge assertion 없음.
+
+### Symbol References
+
+public symbol rename/remove 없음. wire-aware usage 변경 시 `providerChatAssembler` 생성/사용 호출부 전체를 갱신한다.
+
+### Split Judgment
+
+단일 plan이다. request admission, provider observation, public response terminal은 “선택한 provider wire를 canonical Responses로 손실 없이 복원”하는 동일 불변조건이며 각각 따로 PASS할 수 없다.
+
+### Scope Rationale
+
+provider profile schema, Node wire, roadmap, caller identity 분기, 새 config는 변경하지 않는다. `WORK_LOG.md`는 dispatcher-owned라 수정하지 않는다. 계약/spec은 현재 문구가 선택된 fix와 충돌할 때만 좁게 보정한다.
+
+### Final Routing
+
+- evaluation_mode: `isolated-reassessment`
+- finalizer: `finalize-task-policy.sh`, mode `pair`
+- closures: build/review scope, context, verification, evidence, ownership, decision closed

+
+## Implementation Checklist
+
+- [ ] Implement REVIEW_API-1 effective Messages token-limit admission and body mapping with fail-closed tests.
+- [ ] Implement REVIEW_API-2 wire-aware Anthropic usage preservation and canonical Responses usage tests.
+- [ ] Implement REVIEW_API-3 sanitized bridge error and exactly-one terminal lifecycle tests.
+- [ ] Implement REVIEW_API-4 exact test inventory verification, then run focused/package/race/diff verification.
+- [ ] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.
+
+### [REVIEW_API-1] Close Messages max-token admission
+
+#### Problem
+
+`provider_normalization.go:535-538` requires `max_output_tokens`, while the accepted test request omits it and the fake suppresses the body-build error.
+
+#### Solution
+
+Apply the existing model-catalog output-token policy to the bridge request before selection/body construction. Messages must receive a positive effective `max_tokens`; otherwise return `errProviderRequestValidation` before tunnel dispatch. Do not invent a global constant.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/responses_handler.go`: freeze effective catalog token policy for bridge preparation.
+- [ ] `apps/edge/internal/openai/provider_normalization.go`: map/validate positive Messages `max_tokens`.
+- [ ] `apps/edge/internal/openai/responses_protocol_profile_test.go`: assert body and zero-dispatch failure.
+
+#### Test Strategy
+
+Add normal caller/catalog mapping and no-effective-limit rejection cases to exact profile tests.
+
+#### Verification
+
+Run the exact profile inventory and focused test commands in Final Verification.
+
+### [REVIEW_API-2] Preserve Anthropic usage
+
+#### Problem
+
+`stream_gate_tunnel_codec.go:367-510` and `provider_observation.go:152-218` do not parse Anthropic Messages usage.
+
+#### Solution
+
+Bind the selected provider wire to the existing attempt assembler. Parse non-stream `usage`, streaming `message_start.usage.input_tokens`, and `message_delta.usage.output_tokens` into the existing observation/holder without creating a second terminal or metric owner.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/provider_observation.go`: wire-aware Messages usage parsing.
+- [ ] `apps/edge/internal/openai/responses_stream_gate.go`: bind provider wire on initial/recovery attempts.
+- [ ] `apps/edge/internal/openai/responses_protocol_profile_test.go`: non-stream canonical usage assertion.
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: streaming usage assertion.
+
+#### Test Strategy
+
+Fixtures must contain non-zero input/output counts and assert canonical total.
+
+#### Verification
+
+Run exact response bridge tests plus package/race.
+
+### [REVIEW_API-3] Sanitize bridge errors and terminal lifecycle
+
+#### Problem
+
+`openAIResponsesPoolReleaseSink.CommitTerminal` raw-relays provider error bodies regardless of public wire.
+
+#### Solution
+
+Gate raw error relay to native Responses passthrough. Messages/Chat bridge errors use the canonical sanitized Responses error path and emit exactly one terminal and one `[DONE]`.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/responses_stream_gate.go`: public-wire-aware error terminal.
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: exact terminal/error tests.
+
+#### Test Strategy
+
+Exercise handler/runtime sink, not codec only. Assert no provider secret/header/body leak.
+
+#### Verification
+
+Run exact response bridge tests and package/race.
+
+### [REVIEW_API-4] Make verification prove test inventory
+
+#### Problem
+
+Go regex test execution succeeds when alternatives name absent tests.
+
+#### Solution
+
+Add the four missing exact tests and precede focused execution with deterministic `go test -list` plus `rg` count/name check.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/responses_protocol_profile_test.go`: exact non-stream response tests.
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: exact streaming terminal/error tests.
+- [ ] `agent-task/responses_provider_bridge/CODE_REVIEW-cloud-G08.md`: actual evidence.
+
+#### Test Strategy
+
+All five exact names must be listed before execution.
+
+#### Verification
+
+Use Final Verification verbatim.

+# Responses Provider Bridge Plan
+
+## For the Implementing Agent
+
+`CODE_REVIEW-cloud-G08.md`의 구현 담당 섹션 작성은 필수다. 아래 범위만 구현하고 검증 명령을 실제로 실행한 뒤, 결과 원문과 구현 결정을 active review 파일에 기록하고 두 active 파일은 그대로 둔 채 review 준비 완료를 보고한다. 최종 판정, 사용자 리뷰 분류, archive 이동, `complete.log` 작성은 code-review skill 전용이다. 막히면 blocker, 시도한 명령/출력, 재개 조건만 구현 증거란에 남기고 사용자 입력 도구 호출, control-plane stop 파일 생성, 다음 상태 분류를 하지 않는다.
+
+## Background
+
+Codex는 표준 설정에서 `/v1/responses` wire만 사용한다. 현재 IOP provider-pool은 Responses ingress를 native Responses operation으로만 입장시키므로 Claude Messages 및 Gemini OpenAI-compatible Chat profile을 dispatch 전에 거부한다. 이 plan은 caller/agent별 분기 없이 선택된 protocol profile에 따라 Responses 요청과 응답을 기존 provider wire로 변환하는 한 경계만 추가한다.

+
+### SDD Criteria
+
+not applicable. 이 작업은 현재 Milestone에 연결하지 않은 외부 API 호환성 결함 수정이며, 새 제품 의미나 저장 상태를 정의하지 않는다.
+
+### Verification Context
+
+- handoff 문서는 없고, 실제 dev cross-test 결과를 재현 근거로 사용했다.
+- Codex → GPT는 통과했지만 Codex → Claude/Gemini는 파일 생성 전에 `no provider profile supports the requested Responses operation`으로 실패했다. Claude Code caller의 Claude/Gemini/GPT 및 OpenCode의 표준 provider 설정은 통과했다.
+- `responses_handler.go:323-424`는 Responses 요구사항으로 후보를 고른 뒤 `protocolTunnelPreparer(... OperationResponses)`와 Responses body rewrite만 사용한다.
+- `provider_normalization.go:429-564`는 Responses 요구사항에서 stream/structured-output을 수집하지 않고, `selectProviderOperation`에 Responses ingress driver 분기가 없어 Claude/Gemini profile을 거부한다.
+- `anthropic_handler.go:658-710`은 반대 방향인 Messages ingress를 profile별 Messages/Chat/Responses로 변환하고, `anthropic_handler.go:318-340`은 선택 operation별 응답 writer를 사용한다. 이번 구현도 동일한 profile-operation 원칙을 따른다.
+- 기존 StreamGate는 Responses caller에 native Responses tunnel bytes를 그대로 노출한다. bridge operation에서는 provider Chat/Messages wire를 그대로 내보내면 안 되므로, provider operation으로 decode한 semantic event를 caller-facing Responses JSON/SSE로 다시 render해야 한다.
+- 캐시된 Go test 결과는 허용하지 않는다. 모든 Go 명령은 `-count=1`을 사용한다.
+
+#### External Verification Preflight
+
+- runner: `ssh toki@toki-labs.com`
+- repo/workdir: `/Users/toki/agent-work/iop-dev`
+- 기준 branch: `dev`; live 검증 직전 local/remote/runner의 exact SHA가 같고 runner가 clean이어야 한다.
+- 기존 확인 CLI: Claude Code `2.1.177`, Codex `0.146.0`, OpenCode `1.18.3`; live 검증 전에 다시 `--version`으로 확인한다.
+- endpoint: `https://toki-labs.com:18083/v1`; Edge listener `18083`, Node TCP `18084`.
+- CA: `/Users/toki/agent-work/iop-dev/build/dev-runtime/.secrets/credential-plane/ca.pem`; Codex/agent 설정에는 복사된 사용자 소유 CA 경로를 사용하며 tracked 파일에 인증서나 token을 넣지 않는다.
+- secret source: runner의 SOPS/age-managed dev secret. raw token, key, header 값은 task evidence에 기록하지 않는다.
+- runtime identity: 기존 실행 중 binary를 최신으로 간주하지 않는다. `agent-test/dev/rules.md`와 private `dev-runtime-deploy` skill에 따라 exact verified SHA에서 Edge 및 참여 Node를 rebuild/redeploy/restart하고 binary source identity, process, port를 확인한다.
+- OS/arch: runner macOS arm64, dev-runtime 참여 Node에는 macOS, Linux arm64, Windows amd64 산출물이 있으므로 같은 source ref에서 전체 rebuild한다.
+- source가 origin에 없거나 runner SHA가 다르면 live test를 시작하지 않는다. 먼저 승인된 commit/push 흐름으로 exact implementation SHA를 `dev`에 반영한 뒤 clean sync한다.
+- 성공했던 cross path는 반복하지 않는다. 배포 후 Codex 표준 custom model provider 설정으로 Claude와 Gemini direct route만 각각 한 cycle 실행하고, 각 cycle은 workspace 내부 파일 생성 및 내용 확인까지 포함한다.
+
+### Test Coverage Gaps
+
+| Behavior | Existing coverage | Gap to close |
+|---|---|---|
+| native Responses profile raw passthrough | `responses_protocol_profile_test.go` | 그대로 유지하는 회귀 assertion 필요 |
+| Responses → Anthropic Messages request/response | 현재 거부 테스트만 존재 | non-stream text/tool/usage 및 unsupported field 테스트 필요 |
+| Responses → Gemini Chat request/response | effort rewrite만 존재 | reasoning, tool call/result, thought signature 왕복 테스트 필요 |
+| provider Chat/Messages stream → Responses SSE | 없음 | fragmented delta, tool args, reasoning, terminal exactly-once 테스트 필요 |
+| bridge 중 오류/지원 불가 control | Responses operation 부재만 검증 | dispatch 전 fail-closed와 sanitized error 테스트 필요 |
+
+### Symbol References
+
+기존 public symbol rename/remove는 없다. `selectProviderOperation` 호출 지점은 `anthropic_bridge.go`, `anthropic_handler.go`, `provider_normalization.go`, `responses_handler.go`, `single_request_provider_stage.go`, `single_request_work_stage.go`, 관련 테스트에 있으며 기존 ingress 동작을 유지해야 한다. `newOpenAITunnelEndpointCodec` 호출 지점은 Responses/Chat StreamGate runtime과 pipeline tests에 있으므로 새 provider-wire 선택 인자는 모든 호출부에서 명시한다.
+
+### Split Judgment
+
+단일 plan이다. 분리할 수 없는 invariant는 “provider profile이 선택한 wire로 요청을 보냈다면 같은 attempt의 응답을 원래 Responses caller 계약으로 정확히 복원한다”이다. admission/request 변환과 response/SSE 복원을 따로 배포하면 잘못된 wire가 caller에게 노출되므로 분리하지 않는다.
+
+### Scope Rationale
+
+- `packages/go/config`의 built-in profile/schema는 이미 Messages, Chat, Responses operation과 Gemini effort/tool-call normalization을 표현하므로 변경하지 않는다.
+- agent extension, proxy extension, caller product-name 분기, Codex 전용 설정 키를 추가하지 않는다. 일반 custom model provider의 Responses wire만 전제로 한다.
+- Gemini reasoning 자체의 새 `thinkingLevel` 호환이나 profile mapping 확대는 별도 항목이다. 이번 plan은 현재 profile이 이미 선언한 reasoning mapping만 보존한다.
+- `apps/agent/**`, bench agent 설치/config, AGY 경로, current Milestone/roadmap은 수정하지 않는다.
+- native OpenAI Responses raw passthrough와 legacy nil-profile fallback은 유지한다.
+
+### Final Routing

+
+### [API-1] Profile-selected Responses request bridge
+
+#### Problem
+
+`provider_normalization.go:429-443` extracts only tools and effort, and `provider_normalization.go:505-528` has no `OperationResponses` driver selection. `responses_handler.go:409-424` also binds the preparer to native Responses before the selected plan is applied.
+
+```go
+// apps/edge/internal/openai/provider_normalization.go:505
+operations := []config.ProtocolOperation{ingress}
+switch ingress {
+case config.OperationMessages:
+    // ...
+case config.OperationChatCompletions:
+    // ...
+}
+```
+
+#### Solution
+
+Add `OperationResponses` selection: `openai_responses → responses`, `anthropic_messages → messages`, `openai_chat → chat_completions`, subject to capability and normalized requirements. Decode `stream`, tools, reasoning effort, token/output limits, structured output, tool choice, parallel calls, and input item variants needed to decide lossless eligibility. For the selected plan, build the provider-native body and operation/path/header contract instead of invoking the native Responses-only preparer.
+
+```go
+// after: selected profile controls the provider wire
+case config.OperationResponses:
+    switch profile.Driver {
+    case config.ProtocolDriverOpenAIResponses:
+        operations = []config.ProtocolOperation{config.OperationResponses}
+    case config.ProtocolDriverAnthropicMessages:
+        operations = []config.ProtocolOperation{config.OperationMessages}
+    case config.ProtocolDriverOpenAIChat:
+        operations = []config.ProtocolOperation{config.OperationChatCompletions}
+    }
+```
+
+Map Responses `instructions`, message/input items, function calls/results, tools/tool choice, `parallel_tool_calls`, max output tokens, stream, structured output, and the profile-declared reasoning effort. Reuse the existing opaque Gemini thought-signature tool-id envelope: encode returned signature into Responses `call_id`, then decode it when the caller sends `function_call_output`. Reject controls/items that the selected wire cannot preserve before provider dispatch; do not silently drop unknown semantic controls.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/provider_normalization.go`: requirements, operation selection, Responses→Messages/Chat request converters, validation.
+- [ ] `apps/edge/internal/openai/responses_handler.go`: apply selected operation, path, headers, and body for initial/recovery attempts.
+- [ ] `apps/edge/internal/openai/anthropic_bridge.go`: reuse the existing Chat/Anthropic types and opaque Gemini signature helpers without renaming public behavior.
+
+#### Test Strategy
+
+Write tests in `responses_protocol_profile_test.go`:
+
+- `TestResponsesProtocolProfileBridgesToAnthropicMessages`: body/operation/path, text/tool/result/max-token mapping.
+- `TestResponsesProtocolProfileBridgesToGeminiChat`: effort mapping, Chat body, tool choice, signature replay.
+- `TestResponsesProtocolProfileBridgeRejectsUnrepresentableControls`: HTTP 400 before tunnel dispatch.
+- Update the old Anthropic rejection cases to assert admission only when the requested features are representable.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run 'TestResponsesProtocolProfile(BridgesToAnthropicMessages|BridgesToGeminiChat|BridgeRejectsUnrepresentableControls|OperationPassthrough|OperationAdmissionTable)$'
+```
+
+Expected: all named tests pass; native Responses and legacy behavior remain green.
+
+### [API-2] Convert provider responses and streams to Responses
+
+#### Problem
+
+`responses_stream_gate.go:1166-1183` always decodes a tunnel as Responses, while `responses_stream_gate.go:441-443` exposes raw tunnel wire for streaming attempts. After request bridging this would parse or return Anthropic/Chat wire as if it were Responses.
+
+```go
+// apps/edge/internal/openai/responses_stream_gate.go:1177
+tunnelSource := newOpenAITunnelEndpointEventSource(
+    transport.tunnel.Stream(), transport.tunnel.WaitTimeout(),
+    rewriter, assembler, openAIRebuildEndpointResponses, codecState,
+)
+```
+
+#### Solution
+
+Derive the provider decoder from `RunDispatch.ProfileOperation`: Responses remains lossless raw passthrough; Chat and Messages are decoded as provider wire and rendered through the existing Responses sink. Extend the endpoint codec with a Messages decoder or a narrow provider-wire discriminator, and ensure non-stream JSON and streaming SSE both produce canonical Responses message/reasoning/function-call items, usage, incomplete status, safe errors, and exactly one terminal. Keep response IDs/model echo stable at the public route and preserve Gemini signatures in the opaque call ID.
+
+```go
+// after: provider wire and public wire are independent
+providerWire := responsesProviderWire(dispatch.ProfileOperation)
+publicWire := responsesPublicWire(providerWire) // raw only for native Responses
+tunnelSource := newOpenAITunnelEndpointEventSource(
+    transport.tunnel.Stream(), transport.tunnel.WaitTimeout(),
+    rewriter, assembler, providerWire, codecState,
+)
+```
+
+The bridge must handle fragmented Chat/Messages tool arguments, reasoning deltas, usage-only/final frames, provider error frames, and terminal ordering. Do not create a second response owner outside StreamGate.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/stream_gate_tunnel_codec.go`: decode Chat/Messages/Responses provider frames into normalized events and usage-safe state.
+- [ ] `apps/edge/internal/openai/responses_stream_gate.go`: select raw vs bridge rendering per attempt operation for initial and recovery paths.
+- [ ] `apps/edge/internal/openai/provider_normalization.go`: non-stream provider response→Responses conversion helpers.
+
+#### Test Strategy
+
+Write tests in `responses_protocol_profile_test.go` and `stream_gate_pipeline_test.go`:
+
+- `TestResponsesProtocolProfileAnthropicBridgeResponse`
+- `TestResponsesProtocolProfileGeminiBridgeResponseAndSignature`
+- `TestResponsesProviderBridgeStreaming`: table over Chat and Messages with fragmented text/reasoning/tool deltas.
+- `TestResponsesProviderBridgeStreamingTerminalExactlyOnce`
+- `TestResponsesProviderBridgeProviderErrorSanitized`
+
+Assertions include valid Responses JSON/SSE, function call ID/name/arguments, signature replay, usage mapping, event order, one completed/error terminal, one `[DONE]`, and no provider-native framing leak.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run 'TestResponses(ProtocolProfileAnthropicBridgeResponse|ProtocolProfileGeminiBridgeResponseAndSignature|ProviderBridgeStreaming|ProviderBridgeStreamingTerminalExactlyOnce|ProviderBridgeProviderErrorSanitized)$'
+```
+
+Expected: all named bridge response tests pass for non-stream and stream fixtures.
+
+### [API-3] Lock compatibility with tests and contracts
+
+#### Problem
+
+`agent-contract/outer/openai-compatible-api.md` and `agent-spec/input/openai-compatible-surface.md` currently state provider-pool Responses requires a native Responses operation and uses raw passthrough. That statement becomes incomplete once profile-selected Messages/Chat bridges are supported.
+
+```text
+# agent-spec/input/openai-compatible-surface.md:235
+A provider model-group route relays /v1/responses to the selected provider when that candidate declares the Responses operation/capability.
+```
+
+#### Solution
+
+Document that native Responses candidates preserve raw bytes, while Anthropic Messages and OpenAI Chat candidates may be selected only when every requested Responses feature can be represented and their responses are converted back to Responses. State fail-closed behavior, profile-driven reasoning mapping, opaque Gemini tool signature replay, and no caller identity branch. Keep normalized non-provider limitations unchanged.
+
+#### Modified Files and Checklist
+
+- [ ] `apps/edge/internal/openai/responses_protocol_profile_test.go`: handler/admission/non-stream regression matrix.
+- [ ] `apps/edge/internal/openai/stream_gate_pipeline_test.go`: streaming codec/terminal regression matrix.
+- [ ] `agent-contract/outer/openai-compatible-api.md`: external request/response compatibility contract.
+- [ ] `agent-spec/input/openai-compatible-surface.md`: living implementation spec and change history.
+
+#### Test Strategy
+
+Tests are mandatory because this is a public API compatibility bug fix. No new test file is needed; extend the two existing focused suites.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai
+rg --sort path -n 'Responses.*(Messages|Chat)|Gemini.*(signature|thought)' agent-contract/outer/openai-compatible-api.md agent-spec/input/openai-compatible-surface.md
+```
+
+Expected: package tests pass fresh and both documents contain the bridge boundary without contradicting native passthrough.

+
+## Final Verification
+
+Run locally with fresh results:
+
+```bash
+gofmt -w apps/edge/internal/openai/provider_normalization.go apps/edge/internal/openai/responses_handler.go apps/edge/internal/openai/anthropic_bridge.go apps/edge/internal/openai/stream_gate_tunnel_codec.go apps/edge/internal/openai/responses_stream_gate.go apps/edge/internal/openai/responses_protocol_profile_test.go apps/edge/internal/openai/stream_gate_pipeline_test.go
+go test -count=1 ./apps/edge/internal/openai -run 'TestResponses(ProtocolProfile|ProviderBridge)'
+go test -count=1 ./apps/edge/internal/openai
+go test -race -count=1 ./apps/edge/internal/openai -run 'TestResponsesProviderBridgeStreaming'
+git diff --check
+```
+
+Expected: formatting produces no unplanned paths, all tests pass, race detector is clean, and `git diff --check` is empty.
+
+Before live validation, require an approved exact implementation commit on `origin/dev`, then run the private `dev-runtime-deploy` skill from its clean-sync step through whole-runtime rebuild/redeploy/restart and identity/port checks. On the runner record only sanitized output for:
+
+```bash
+ssh toki@toki-labs.com '/bin/zsh -lc '\''cd /Users/toki/agent-work/iop-dev && git status --short --branch && git rev-parse HEAD && git rev-parse origin/dev && command -v go && go version && codex --version && claude --version && opencode --version && lsof -nP -iTCP:18083 -sTCP:LISTEN && lsof -nP -iTCP:18084 -sTCP:LISTEN'\'''
+```
+
+Expected: clean `dev`, `HEAD == origin/dev == approved implementation SHA`, required tools exist, rebuilt Edge owns `18083`, and Node ingress listens on `18084`.
+
+Using standard Codex `model_providers.<id>.wire_api="responses"` custom providers and the existing copied CA/token setup, run only these two one-cycle cases against `https://toki-labs.com:18083/v1`:
+
+1. Codex → IOP Claude route: create a uniquely named file in a temporary test workspace and verify exact requested content.
+2. Codex → IOP Gemini route: create a different uniquely named file, verify exact content, and include one normal tool-call continuation so call ID/signature replay is exercised.
+
+Expected: both commands exit 0, both files exist with exact content, no extension/workaround is enabled, and sanitized Edge evidence shows the selected provider operation is Messages for Claude and Chat for Gemini. Raw credentials, prompts, tool payloads, and generated file contents stay out of tracked evidence.
+
+After completing all code changes, fill implementation-owned sections in `CODE_REVIEW-*-G??.md`.

+# Gemini Reasoning Normalization Plan
+
+## For the Implementing Agent
+
+기존 operation-scoped `normalization.effort` 경계만 사용한다. 구현·검증 뒤 `CODE_REVIEW-cloud-G04.md`의 구현 담당 섹션에 실제 결과를 기록하고 active pair를 둔 채 review 준비 완료를 보고한다. verdict, archive, `complete.log`, 사용자 질문은 구현 담당 범위가 아니다.
+
+## Background
+
+Gemini profile은 이미 `normalization.effort` 방식으로 reasoning grade를 처리하지만 현재 levels가 IOP 전체 등급의 identity mapping이라 Gemini Chat의 portable 상한을 넘는 `xhigh|max`도 그대로 전달한다. 별도 adapter나 `thinking_level` 변환기를 만들지 않고 profile mapping만 교정해 기존 normalization 흐름이 올바른 provider value를 선택하게 한다.
+
+## Analysis
+
+### Files Read
+
+- `packages/go/config/protocol_profile.go`
+- `packages/go/config/protocol_profile_test.go`
+- `apps/edge/internal/openai/provider_normalization.go`
+- `apps/edge/internal/openai/responses_protocol_profile_test.go`
+- `agent-contract/inner/edge-config-runtime-refresh.md`
+- `agent-contract/outer/openai-compatible-api.md`
+- `agent-spec/input/openai-compatible-surface.md`
+- `agent-test/dev/rules.md`
+- `agent-ops/rules/project/domain/platform-common/rules.md`
+
+### SDD Criteria
+
+not applicable. 기존 normalization profile의 작은 호환성 결함 수정이다.
+
+### Verification Context
+
+- 최신 `dev` 기준 `protocol_profile.go`의 Gemini Chat effort는 `identityEffortMapping(...)`이며 `none|low|medium|high|xhigh|max`를 모두 그대로 매핑한다.
+- 공통 `MapReasoningEffort`는 exact level이 없으면 가장 가까운 명시적 하위 등급을 고르고 상향하지 않는다. 이 함수가 source of truth다.
+- 진행 중인 `responses_provider_bridge`도 `selectProviderOperation`에서 동일한 profile mapping을 사용하므로 변환 코드를 추가할 필요가 없다.
+- Gemini 공식 OpenAI-compatible Chat은 `reasoning_effort`를 지원한다. `thinking_level`/`thinking_budget`을 함께 보내면 안 되므로 IOP가 native field를 합성하지 않는다.
+- fresh test는 `-count=1`로 실행한다.
+
+#### External Verification Preflight
+
+- runner/workdir: `ssh toki@toki-labs.com`, `/Users/toki/agent-work/iop-dev`
+- clean `dev`에서 `HEAD == origin/dev == approved implementation SHA`를 확인한다.
+- exact source로 dev-runtime Edge/참여 Node를 rebuild/redeploy/restart하고 `18083/18084` listener와 binary identity를 확인한다.
+- existing copied CA 및 SOPS/age-managed token을 사용하며 secret 원문은 evidence에 남기지 않는다.
+- Gemini direct route에서 standard Responses caller의 `low`, `high`, `max` 한 cycle씩 확인한다. extension이나 `thinking_level` 우회는 사용하지 않는다.
+
+### Test Coverage Gaps
+
+| Behavior | Existing coverage | Gap |
+|---|---|---|
+| nearest-lower mapping | custom OpenAI profile | built-in Gemini mapping 없음 |
+| Gemini tools + effort | profile은 `WithTools=true` | xhigh/max fallback 회귀 없음 |
+| Responses→Gemini | 진행 중 bridge가 공통 selector 사용 | corrected mapping 상속 assertion 없음 |
+
+### Symbol References
+
+rename/remove 없음. `MapReasoningEffort`와 `selectProviderOperation` call sites는 변경하지 않는다.
+
+### Split Judgment
+
+단일 plan이다. compact invariant는 “Gemini profile의 declared levels가 기존 공통 nearest-lower normalization을 통해 provider-supported grade만 반환한다”이다.
+
+### Scope Rationale
+
+- `provider_normalization.go`의 알고리즘과 handler/adapter에 새 정규화 경계를 추가하지 않는다.
+- `thinking_level`, `thinking_budget`, model-name 분기, caller/agent 분기, extension 우회를 추가하지 않는다.
+- Gemini-native `thinkingConfig`, response reasoning text, `thought_signature`는 변경하지 않는다.
+- portable scale은 `low|medium|high`로 둔다. `xhigh|max`는 기존 규칙으로 `high`, `none`은 지원 mapping이 없어 fail closed한다.
+
+### Final Routing
+
+- evaluation_mode: `first-pass`; finalizer=`finalize-task-policy.sh`, mode=`pair`
+- build/review closures: all true
+- build scores: scope=1,state=0,blast=1,evidence=1,verification=1; route=`local/G04`, basis=`local-fit`
+- review scores: scope=1,state=0,blast=1,evidence=1,verification=1; route=`cloud/G04`, basis=`official-review`
+- large_indivisible_context=false
+- positive loop risks: `boundary_contract`, `variant_product` (2); risk boundary=false
+- recovery signals: review_rework_count=0, evidence_integrity_failure=false; capability gap 없음
+- canonical files: `PLAN-local-G04.md`, `CODE_REVIEW-cloud-G04.md`
+
+## Implementation Checklist
+
+- [ ] Implement API-1 the Gemini portable effort levels inside the existing profile normalization.
+- [ ] Implement API-2 focused config and Responses-bridge regression tests plus contract/spec synchronization.
+- [ ] Run fresh local verification and the exact-source dev Gemini reasoning cycles.
+- [ ] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.
+
+### [API-1] Correct Gemini profile levels
+
+#### Problem
+
+```go
+// packages/go/config/protocol_profile.go:251
+string(OperationChatCompletions): identityEffortMapping(ProtocolEffortWireGeminiChat, true, true),
+```
+
+Identity mapping declares unsupported upper/disable grades instead of letting the common normalizer choose a supported lower grade or reject.
+
+#### Solution
+
+Replace only the Gemini Chat levels with explicit `low`, `medium`, `high`. Retain `Wire=gemini_openai_chat`, `WithTools=true`, and the existing token-budget fact. Do not change `MapReasoningEffort`.
+
+```go
+// after: existing MapReasoningEffort supplies xhigh/max -> high
+ProtocolEffortMappingConf{
+    Wire: ProtocolEffortWireGeminiChat,
+    WithTools: true,
+    TokenBudget: true,
+    Levels: map[string]string{"low":"low", "medium":"medium", "high":"high"},
+}
+```
+
+#### Modified Files and Checklist
+
+- [ ] `packages/go/config/protocol_profile.go`: Gemini Chat levels only.
+
+#### Test Strategy
+
+Write `TestGeminiProtocolProfileReasoningEffortScale` in `protocol_profile_test.go`: low/medium/high exact, xhigh/max→high, none unsupported, with-tools true, and `base: gemini` inheritance.
+
+#### Verification
+
+```bash
+go test -count=1 ./packages/go/config -run 'TestGeminiProtocolProfileReasoningEffortScale|TestProtocolProfileEffortNormalizationOverlayAndValidation'
+```
+
+Expected: all cases pass without changing generic normalization.
+
+### [API-2] Prove bridge inheritance and synchronize contracts
+
+#### Problem
+
+No regression test proves that Responses ingress selecting Gemini Chat consumes the corrected profile mapping; documentation does not state Gemini's portable IOP grade behavior.
+
+#### Solution
+
+After `responses_provider_bridge` is present, add a focused assertion that a Responses request with effort `max` selects Gemini Chat and sends `reasoning_effort=high`. Do not add conversion logic in the test's production path. Document that direct native provider fields remain passthrough, while profile-normalized bridges use low/medium/high with nearest-lower fallback and no synthetic native thinking field.
+
+#### Modified Files and Checklist
+
+- [ ] `packages/go/config/protocol_profile_test.go`: profile mapping coverage.
+- [ ] `apps/edge/internal/openai/responses_protocol_profile_test.go`: bridge inheritance coverage only.
+- [ ] `agent-contract/inner/edge-config-runtime-refresh.md`: Gemini operation-scoped levels.
+- [ ] `agent-contract/outer/openai-compatible-api.md`: Responses→Gemini reasoning semantics.
+- [ ] `agent-spec/input/openai-compatible-surface.md`: living implementation state/change history.
+
+#### Test Strategy
+
+Write `TestResponsesProtocolProfileGeminiEffortFallsBackToHigh`. Assert selected operation is Chat, provider body contains `reasoning_effort=high`, tools still admit the candidate, and no `thinking_level`/`thinking_budget` is synthesized.
+
+#### Verification
+
+```bash
+go test -count=1 ./apps/edge/internal/openai -run 'TestResponsesProtocolProfileGeminiEffortFallsBackToHigh'
+rg --sort path -n 'Gemini.*reasoning_effort|xhigh|max.*high' agent-contract/inner/edge-config-runtime-refresh.md agent-contract/outer/openai-compatible-api.md agent-spec/input/openai-compatible-surface.md
+```
+
+Expected: bridge test and documents agree with the profile mapping.

+
+Expected: fresh tests pass and the implementation diff contains no handler/adapter reasoning normalizer or native thinking field synthesis.

Write the file, read it back, and then finish with `BENCH_LITE_01_DONE` on its own line followed by the exact full `index.html` in one `html` fenced code block.

+
+## 실행 규칙
+
+- 각 조합은 빈 임시 workspace에서 정확히 한 번만 실행한다.
+- 실패도 결과이며 같은 측정에서 retry, resume, recovery 또는 대체 실행을 하지 않는다.
+- direct 경로는 caller workspace의 `index.html`과 terminal marker를 확인한다.
+- execution preset은 Edge private workspace cleanup 계약을 유지하므로 caller-visible terminal marker와 최종 응답의 exact HTML code block을 확인한다.
+- usage는 caller가 직접 제공한 값만 기록하고 없으면 `미제공`으로 둔다.
+- 기존 원격 SOPS token과 command-scoped managed CA만 사용하며 별도 benchmark token이나 전역 CA override를 만들지 않는다.
+- 이 세션의 execution preset Work는 live `ornith:35b` 바인딩을 사용한다. tracked runtime 설정은 변경하지 않는다.
+- 각 exact HTML source와 SHA-256, `1440×900` desktop 및 `390×844` mobile render만 ignored run evidence에 보존한다. render는 품질 분석 입력이지 제품 경로의 pass/fail gate가 아니다.
+- full source를 얻지 못한 실행은 `실행 실패`와 별개로 `채점 불가`로 기록하며 0점으로 바꾸지 않는다.
+- scorable source에는 실행 후 opaque 평가 ID를 부여한다. 단일 평가 pass에는 ID, source와 두 render만 제공하고 route·model·시간·usage 매핑은 점수와 evidence가 고정된 뒤 결합한다.

+## 공통 평가 기준표 — 100점
+
+평가자는 route, model, 경과 시간과 usage를 보지 않고 opaque 평가 ID, exact source와 두 고정 viewport render만 사용한다. `A`는 명시된 세부 점수를 합산한다. `B`~`D`의 각 5점 항목은 `5=명확히 충족`, `3=대체로 충족하나 눈에 띄는 결함 1개`, `1=일부 흔적만 있거나 결함이 여러 개`, `0=없거나 깨짐`의 네 anchor만 사용한다. 중간 점수는 쓰지 않는다.
+
+| 축 | 세부 기준 | 배점 | 허용 점수 |
+|---|---|---:|---|
+| A. 요청 충족 | 완전한 HTML 문서 4, 내부 `<style>` 4, 외부 asset/framework 없음 4, JavaScript 없음 4, exact meta 1회 4 | 20 | 세부 항목별 0 또는 4 |
+| A. 요청 충족 | `header/main/footer` 3, hero title+CTA 2개 4, feature card 3개 4, service 3개+visible label 4, 720px 이하 실제 breakpoint 5 | 20 | 명시 세부 점수만 합산 |
+| B. 반응형·레이아웃 | desktop hierarchy, mobile reflow, overflow/clipping 방지, component/readability consistency | 20 | 각 0/1/3/5 |
+| C. 사용성·접근성 | heading/landmark 구조, CTA 의미·focus, status의 non-color cue, viewport·대비·가독성 | 20 | 각 0/1/3/5 |
+| D. 시각 완성도 | 정보 위계, palette/type/spacing, component/status cohesion, polish/distinctiveness | 20 | 각 0/1/3/5 |
+
+총점은 `A+B+C+D`의 단순 합이며 별도 가중·정규화·상대 순위 보정은 없다. 요구 위반은 해당 `A` 점수에서만 반영하고 같은 결함을 다른 축에서 중복 감점하지 않는다. 단, 그 위반이 실제 레이아웃·사용성·시각 결함을 별도로 만든 경우에는 해당 render 증거를 적고 감점할 수 있다.
+
+## 단일 평가 기록
+
+각 scorable 산출물마다 아래 한 행과 짧은 evidence block 하나만 작성한다. 모든 산출물 평가가 끝날 때까지 rubric을 바꾸지 않는다.
+
+| 평가 ID | A /40 | B /20 | C /20 | D /20 | 총점 /100 | 채점 상태 |
+|---|---:|---:|---:|---:|---:|---|
+| 미부여-01 | — | — | — | — | — | 미채점 |
+| 미부여-02 | — | — | — | — | — | 미채점 |
+| 미부여-03 | — | — | — | — | — | 미채점 |
+| 미부여-04 | — | — | — | — | — | 미채점 |
+| 미부여-05 | — | — | — | — | — | 미채점 |
+| 미부여-06 | — | — | — | — | — | 미채점 |
+| 미부여-07 | — | — | — | — | — | 미채점 |
+| 미부여-08 | — | — | — | — | — | 미채점 |
+| 미부여-09 | — | — | — | — | — | 미채점 |
+
+Evidence block 형식: `평가 ID — A: 충족/누락 selector와 점수; B~D: source selector 또는 viewport에서 직접 관찰한 근거; 감점: 기준·anchor·사유`. 한 결함당 한 문장으로 제한한다. 평가는 산출물별 한 번만 수행하고, 이후 수정은 합계 산술 오류나 evidence 전사 오류만 허용하며 수정 사유를 같은 block에 남긴다.
+
+이 총점은 고정 rubric과 직접 evidence에 기반한 재검산 가능한 단일 평가 점수다. 반복 표본이나 다중 평가자 합의가 아니므로 통계적 모델 우위나 절대적 품질 척도로 해석하지 않는다.
+
+## 결론
+
+9개 단일 시도와 단일 평가가 끝난 뒤 scorable 결과의 총점과 축별 강점·약점만 짧게 비교한다. 실행 성공률·속도·usage는 품질 총점과 별도로 제시한다. 실패, 채점 불가와 미제공 usage를 0점으로 바꾸거나 반복 실행·통계적 우위로 일반화하지 않는다.
