## 개요

date=2026-07-26
task=m-stream-evidence-gate-core/10+09_policy_hook, plan=3, tag=REVIEW_REVIEW_API

## Archive Evidence Snapshot

- `agent-task/m-stream-evidence-gate-core/10+09_policy_hook/plan_local_G08_2.log`, `agent-task/m-stream-evidence-gate-core/10+09_policy_hook/code_review_cloud_G08_2.log`: `FAIL`(Required 2, Suggested 0, Nit 0). exact-set test에 resolved empty와 applicability missing/extra/duplicate가 없고, storage-envelope test가 실제 tail buffer/prepare/confirm/look-behind lifecycle을 검증하지 않는다.
- 영향 범위는 `packages/go/streamgate/evidence_tail_test.go`다. 직전 생산 변경의 focused/package/race와 `make proto`, Edge/Node transport, stale-symbol search, `git diff --check`는 fresh PASS했다.
- 선행 의존성은 `agent-task/archive/2026/07/m-stream-evidence-gate-core/09_decision_arbiter/complete.log` 하나로 충족된다. Roadmap Targets는 없고 `policy-hook` completion은 후속 `11+09,10_policy_hook_contract`에 유지된다.

## 이 파일을 읽는 리뷰 에이전트에게

> **[REVIEW AGENT ONLY]** 아래 종결 절차는 코드리뷰 에이전트 전용이다. 구현 에이전트는 이 섹션을 실행하지 않는다.

각 항목의 구현을 실제 소스 파일과 대조하고, `검증 결과` 섹션의 출력이 코드와 일치하는지 확인하세요.
리뷰 완료는 아래 순서까지 끝난 상태를 의미합니다.

1. 판정을 append한다.
2. `CODE_REVIEW-cloud-G04.md` → `code_review_cloud_G04_3.log`, `PLAN-local-G04.md` → `plan_local_G04_3.log`로 아카이브한다.
3. PASS이면 `complete.log` 작성 후 active task 디렉터리를 `agent-task/archive/YYYY/MM/m-stream-evidence-gate-core/10+09_policy_hook/`로 이동한다. WARN/FAIL이면 code-review skill이 요구하는 다음 filesystem state를 완전히 작성한다.
4. 이 partial task는 Roadmap Targets가 없으므로 PASS여도 milestone task 완료 이벤트를 보고하지 않는다.
5. 적용 가능한 `코드리뷰 전용 체크리스트` 항목을 최종 `.log` 위치에서 체크한 뒤 보고한다.

- [x] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다.

## 코드리뷰 전용 체크리스트

> **[REVIEW AGENT ONLY]** 이 체크리스트는 코드리뷰 에이전트만 사용한다.
> 구현 에이전트는 이 섹션을 수정하거나 체크하지 않는다.

- [x] `코드리뷰 결과`에 `PASS`, `WARN`, `FAIL` 중 하나의 판정을 append한다.
- [x] 판정과 `차원별 평가`, Required/Suggested/Nit 분류가 서로 일치한다.
- [x] active `CODE_REVIEW-*-G??.md`를 `code_review_cloud_G04_3.log`로 아카이브한다.

- [x] `.gitignore`의 Agent-Ops 관리 block이 `agent-task/**/*.md`와 `agent-task/**/*.log`를 unignore하고 `agent-roadmap/current.md`를 ignore하는지 확인한다.
- [ ] PASS이면 `agent-ops/skills/common/code-review/templates/complete-log-template.md` 기준으로 `complete.log`를 작성하고 active `.md` 파일을 남기지 않는다.
- [ ] PASS이면 active task 디렉터리 `agent-task/m-stream-evidence-gate-core/10+09_policy_hook/`를 `agent-task/archive/YYYY/MM/m-stream-evidence-gate-core/10+09_policy_hook/`로 이동하고 최종 archive 경로에서 이 체크리스트를 갱신한다.

- [ ] PASS split 작업이면 이동 후 active parent는 dispatcher-owned `WORK_LOG.md`와 후속 sibling 때문에 유지한다고 확인한다.
- [x] WARN/FAIL이면 code-review skill의 판정에 맞는 다음 filesystem state를 작성하고 `complete.log`를 작성하지 않는다.

## 계획 대비 변경 사항

계획에 명시된 두 테스트 파일 확장만 수행했다. 수정 파일은 `packages/go/streamgate/evidence_tail_test.go` 하나이다.

- REVIEW_REVIEW_API-1: `TestMultiRequirementPolicyHookExactSetBinding`을 table-driven matrix로 통합하고 `resolvedEmpty`, `applicabilityMissing`, `applicabilityExtra`, `applicabilityDuplicate` sub-case를 추가했다. 기존 `resolvedSubset`/`resolvedExtra`/`resolvedDuplicate`와 정상 `exactSetSuccess` case를 유지하면서 cross-channel `f2` explicit not-applicable 단언을 그대로 유지했다.
- REVIEW_REVIEW_API-2: `TestMultiRequirementPolicyHookStorageEnvelope`에 `runtimeStorageEnvelopeLifecycle` sub-test를 추가했다. 100-rune text 이벤트 + terminal trigger → prepare → confirm 풀 confirm 후 committedCursor=1, pending=0, trailing 80-rune look-behind를 단언한다. 기존 accessor + incompatible aggregate 검증은 유지했다.
- VERIFY-3: focused/package/race/proto/transport를 fresh 실행하고 formatting/diff를 확인했다. 모든 검증이 PASS했다.

## 주요 설계 결정

- REVIEW_REVIEW_API-1: 기존 4개 독립 sub-test를 table-driven matrix로 통합하고 resolved empty, applicability missing/extra, applicability duplicate case를 추가했다. 정상 exact set 검증은 table case로 통합하면서 cross-channel explicit not-applicable 단언을 유지했다.
- REVIEW_REVIEW_API-2: 기존 accessor + incompatible aggregate 검증에 이어 실제 tail lifecycle 서브테스트(runtimeStorageEnvelopeLifecycle)를 추가했다. 100-rune text 이벤트 + terminal trigger → prepare → confirm 풀 confirm → committedCursor=1, pending=0, trailing 80-rune look-behind를 단언한다.
- applicabilityDuplicate는 constructor 수준 오류로 검증한다(내부 map 위조 아님).

## 리뷰어를 위한 체크포인트

- resolved empty/subset/extra/duplicate와 applicability missing/extra/duplicate가 각각 실제 constructor/bind 경계에서 결정적 오류로 거절되는가.
- 정상 exact set의 stable `f1,f2` order와 cross-channel `f2` explicit not-applicable assertion이 유지되는가.
- mixed rolling 80/max 2000 + terminal/max 1500 plan이 runtime channel에 max buffer 1500/effective window 80을 설정하는가.
- 100-rune pending event와 terminal trigger의 prepare/confirm이 한 token, 한 release event, cursor 1, pending empty, 정확한 trailing 80-rune look-behind를 남기는가.
- `evidence_tail_test.go` 외 production/test source, proto, contract/spec/roadmap, dispatcher-owned `WORK_LOG.md`를 수정하지 않았는가.
- focused/package/race/proto/transport와 formatting/diff evidence가 fresh 실행 결과와 일치하는가.

## 섹션 소유권

| Section | Owner | Note |
|---------|-------|------|
| Header comment, 개요, 리뷰 에이전트 지시 | Fixed at stub creation | Implementing agent must not modify or execute these (archive, complete.log, and task-directory archive move are review-agent only) |
| Roadmap Targets | Fixed at stub creation from plan when present | Implementing agent must not modify; code-review copies it into `complete.log` as `Roadmap Completion` only on PASS |
| Archive Evidence Snapshot | Fixed at stub creation from plan when present | Implementing agent uses it as default prior-loop context; read only the specific archive files cited there when more detail is required |
| Agent UI Completion | Mixed | Present only for plan-required agent-ui code work; implementing agent fills actual evidence, review agent applies `구현됨` status/evidence update on PASS and copies the section into `complete.log` |
| 구현 항목별 완료 여부 (item names) | Fixed at stub creation | Implementing agent checks `[ ]` → `[x]` only |
| 구현 체크리스트 (item text/order) | Fixed at stub creation from plan | Implementing agent checks `[ ]` → `[x]` only |
| 코드리뷰 전용 체크리스트 | Review agent only | Implementing agent must not modify or check this section |
| 계획 대비 변경 사항, 주요 설계 결정 | Implementing agent | Replace placeholder text with actual content |
| 리뷰어를 위한 체크포인트 | Fixed at stub creation | Pre-filled from plan |
| 검증 결과 (section headings + commands) | Fixed at stub creation | Implementing agent fills in command output only; command changes require a `계획 대비 변경 사항` entry |
| 코드리뷰 결과 | Review agent appends | Not included in stub |

## 코드리뷰 결과

### 종합 판정

FAIL

### 차원별 평가

| 차원 | 평가 | 근거 |
|---|---|---|
| correctness | Pass | exact-set malformed 행렬과 실제 append/trigger/prepare/confirm 경로는 현재 구현에서 fresh focused/package/race 검증을 통과했다. |
| completeness | Fail | storage-envelope 항목이 계획에 명시된 position-distinct suffix fixture와 대표 `terminal_gate` mode 단언을 구현하지 않았다. |
| test coverage | Fail | 현재 10-rune 주기 문자열은 앞 80 rune과 뒤 80 rune이 같아 선두 slice 회귀도 trailing-suffix assertion을 통과한다. |
| API contract | Pass | 이 후속은 public API를 변경하지 않았고 exact-set/applicability 계약 회귀 행렬은 요구 사례를 포함한다. |
| code quality | Pass | 변경은 기존 테스트 파일 하나에 국한되고 debug/TODO/불필요한 production 변경은 추가하지 않았다. |
| implementation deviation | Fail | `PLAN-local-G04.md`가 요구한 distinct prefix/suffix와 strongest terminal representative 검증이 실제 테스트에 없다. |
| verification trust | Fail | fresh 명령은 모두 PASS했지만 fixture가 잘못된 suffix 방향을 구분하지 못해 핵심 assertion의 신뢰가 부족하다. |

### 발견된 문제

- **Required** — `packages/go/streamgate/evidence_tail_test.go:4737`: `runtimeStorageEnvelopeLifecycle`은 `strings.Repeat("ABCDEFGHIJ", 10)`을 사용해 첫 80 rune과 마지막 80 rune이 동일하다. 따라서 `trimLookBehind`가 suffix 대신 prefix 80 rune을 보존해도 `released == expected`가 통과한다. 또한 mixed plan의 대표 requirement가 `terminal_gate`인지 직접 단언하지 않아 계획의 strongest bounded requirement 조건도 증명하지 않는다. 위치별로 구분되는 100-rune fixture로 바꾸고 prefix와 suffix가 다름을 보장한 뒤 exact trailing 80 rune과 `BlockingRequirement("ch").Mode() == FilterHoldModeTerminalGate`를 단언한다.

Required 1, Suggested 0, Nit 0.

### 다음 단계

WARN/FAIL follow-up: 동일 테스트 함수만 수정하는 최소 테스트 전용 계획으로 mutation-resistant suffix fixture와 representative mode assertion을 추가하고 fresh focused/package/race/proto/transport 검증을 다시 수행한다. `complete.log`와 Roadmap 완료 이벤트는 작성하지 않는다.
