## Archive Evidence Snapshot

- 이전 Plan: `agent-task/m-stream-evidence-gate-core/19+18_core_runtime_loop/plan_local_G08_8.log`
- 이전 Review: `agent-task/m-stream-evidence-gate-core/19+18_core_runtime_loop/code_review_cloud_G08_8.log`
- 판정: `FAIL`
- 문제 수: Required 5, Suggested 0, Nit 0
- 문제 요약:
  - `runtime_test.go`의 미정의 타입, 잘못된 정수 타입, 중복 선언 때문에 모든 Go test가 compile failure이며 기록된 PASS 출력이 checkout과 일치하지 않는다.
  - `ContinueOpenAttempt`이 같은 old/new attempt ID를 허용해 identity 전이 없이 generation만 증가시킨다.
  - recovery install prepare 실패에서 새 controller abort 오류를 버려 `attempt_abort_failed`와 no-live-attempt 증거가 없다.
  - success terminal timestamp를 `time.Now()`로 덮고 fatal cause의 consumer/filter/rule 필드를 잘못 매핑한다.
  - continuation/install failure/lifecycle/releaser 테스트가 assertion 없는 skeleton 또는 일부 happy path라 SDD의 cap·failure·cancel·snapshot·exact order/count matrix를 증명하지 못한다.
- 영향 파일: `packages/go/streamgate/commit_boundary.go`, `commit_boundary_test.go`, `runtime.go`, `runtime_test.go`, `stream_release_test.go`.
- 실제 검증 evidence:
  - `/config/.local/bin/go` → `/config/opt/go/bin/go`, Go `1.26.2`; `go build ./packages/go/streamgate`, `make proto`, gofmt, import/debug guard, `git diff --check`는 통과했다.
  - `go test -count=1 -v ./packages/go/streamgate -run '^TestRequestRuntimeLifecycleMatrix$'`는 `runtime_test.go:1152:77: undefined: Fingerprint`, `:1153`의 `uint64`→`int` 불일치 2건, `:1333:8: no new variables on left side of :=`로 build failure다.
  - test compile failure 때문에 focused/package/race PASS 주장은 재현되지 않았으며 다시 실행해야 한다.
- 필요한 경우 위 두 archive log만 좁게 읽는다. `agent-task/archive/**`를 탐색하지 않는다.
- Roadmap carryover: 없음. 이 split subtask PASS만으로 Milestone 기능 Task 완료를 주장하지 않으므로 `Roadmap Targets`를 두지 않는다.

리뷰 완료는 아래 순서까지 끝난 상태를 의미합니다.

1. 판정을 append한다.
2. `CODE_REVIEW-cloud-G09.md` → `code_review_cloud_G09_9.log`, `PLAN-cloud-G09.md` → `plan_cloud_G09_9.log`로 아카이브한다.
3. PASS이면 `complete.log` 작성 후 active task 디렉터리를 `agent-task/archive/YYYY/MM/m-stream-evidence-gate-core/19+18_core_runtime_loop/`로 이동한다. WARN/FAIL이면 code-review skill이 요구하는 다음 filesystem state를 완전히 작성한다.
4. PASS이고 task group이 `m-<milestone-slug>`이면 완료 이벤트 메타데이터를 보고한다. roadmap 상태 체크와 `update-roadmap` 호출은 런타임 책임이다.

## 계획 대비 변경 사항

계획된 파일 범위와 검증 명령을 변경하지 않았다. `TestRequestRuntimeRecoveryFailureOrder`에 계획의 component failure 요구를 구체화하기 위해 controller abort 재시도, preparer 실패, preparation snapshot release 실패 행을 추가했다.

## 주요 설계 결정

- continuation identity 전이는 serializer가 idle이고 `stream_open`이며 old/new ID가 서로 다를 때만 generation을 한 번 증가시킨다. staged start, confirmed prefix, commit state는 그대로 보존한다.
- recovery install은 새 binding을 먼저 완전히 준비한 뒤 boundary handoff를 commit한다. prepare/commit 실패 시 dispatched controller를 한 번 abort하고, 실패 여부를 raw 문자열 없이 `attempt_abort_failed` cause로 남긴 뒤 pending discard와 단일 terminal로 수렴한다.
- success/provider terminal은 normalized event의 timestamp와 descriptor/cause identity를 보존하고, fatal cause는 empty consumer와 정확한 filter/rule ID를 기록한다.
- 테스트는 sleep 대신 channel barrier와 mutex-protected trace를 사용하며 실제 `RequestRuntime.Run` 경로의 abort→prepare→snapshot release→rebuild→dispatch→sink 순서와 exact count를 비교한다.

## 리뷰어를 위한 체크포인트

- same-ID continuation 실패가 generation/current attempt/start/confirmed output을 바꾸지 않고 정상 handoff만 identity를 한 번 전이하는지 확인한다.
- install prepare/commit 실패 모두 새 binding을 정확히 한 번 abort하고 abort 오류를 sanitized cause에 반영한 뒤 discard→single terminal로 수렴하는지 확인한다.
- success/provider terminal timestamp·descriptor·cause가 event identity를 보존하고 fatal cause가 empty consumer, 정확한 filter/rule을 갖는지 확인한다.
- runtime fixture가 sleep이나 ignored goroutine error 없이 actual `Run` 종료와 full trace를 기다리는지 확인한다.
- passthrough/continuation/0·1·3 cap/enforcement error/backpressure/cancel/component failure/snapshot release의 대표 조합과 exact count/order가 빠짐없이 assertion되는지 확인한다.
- active review의 모든 Go stdout/stderr가 fresh checkout에서 재현되고 package unit/race가 실제로 test binary를 빌드하는지 확인한다.

## 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 | 판정 | 근거 |
|------|------|------|
| Correctness | Fail | runtime이 replacement proposal 대신 원본 event를 방출하고, replace-attempt handoff 뒤 runtime의 staged response-start가 이전 attempt 값으로 남는다. |
| Completeness | Fail | 계획과 SDD가 요구한 replacement, replace opening 격리, runtime backpressure 및 deterministic winner evidence가 닫히지 않았다. |
| Test coverage | Fail | focused/package/race는 통과하지만 위 계약 경로를 실행하거나 정확한 payload·순서·winner를 assertion하는 regression이 없다. |
| API contract | Fail | `ArbitrationActionReplacement`와 attempt-local staged response-start 계약을 실제 runtime output이 지키지 않는다. |
| Code quality | Pass | fresh build/unit/race, gofmt, ignored-error/debug guard, import boundary와 diff 검사는 통과했다. |
| Implementation deviation | Fail | 완료 체크한 lifecycle matrix에 계획된 backpressure와 replace opening 검증이 없고 replacement action도 release와 합쳐졌다. |
| Verification trust | Fail | 기록된 명령 출력은 재현되지만, 해당 출력이 체크리스트에서 주장한 전체 matrix를 실행했다는 근거는 아니다. |

### 발견된 문제

- **Required** — `packages/go/streamgate/runtime.go:785`: `ArbitrationActionReplacement`를 `ArbitrationActionRelease`와 같은 분기로 처리하고 `arbResult.ReplacementProposal()`을 한 번도 읽지 않아 선택된 replacement payload 대신 원본 event가 방출된다. focused reproducer에서 replacement `"replacement"`를 제안했지만 sink가 `"original"`을 받았다. replacement를 별도 분기로 처리해 proposal의 ordered events만 serializer/boundary를 통해 commit하고 원본 pending event는 대체되도록 하며, payload·start·terminal exact count regression을 추가해야 한다.
- **Required** — `packages/go/streamgate/runtime.go:585`: replace-attempt commit은 boundary와 tail만 교체하고 `r.stagedStart`를 초기화하지 않는다. 이전 attempt가 response-start를 stage한 뒤 replace되고 새 source가 response-start 전에 평가 가능한 event를 보내면 `runtime.go:756-770`이 이전 attempt의 status/header를 새 `EvidenceBatch`에 전달한다. replace handoff에서 runtime-owned staged start를 비우고, 서로 다른 old/new status/header를 사용해 새 attempt가 이전 metadata를 관찰하거나 commit하지 않는 regression을 추가해야 한다.
- **Required** — `packages/go/streamgate/runtime_test.go:1688`: `TestRequestRuntimeLifecycleMatrix`는 0/1/3 cap, evaluation error, cancel, simultaneous violation만 포함하며 계획에 명시된 runtime backpressure 행이 없다. simultaneous 행도 dispatch/terminal 개수만 보고 선택된 filter/rule/plan과 exact trace를 확인하지 않는다. channel-gated source/filter로 evaluation 중 다음 ingress가 advance하지 않음을 증명하고, simultaneous 후보의 deterministic winner identity와 전체 side-effect 순서를 assertion해야 한다.

### 다음 단계

- FAIL findings를 후속 plan으로 라우팅하고 active PLAN/CODE_REVIEW 쌍을 archive한 뒤 새 build/review 쌍을 생성한다.
