## 요약

10개 plan/code-review 루프에서 CommitBoundary와 StreamReleaser의 irreversible commit, exact confirmation, discard/cancel/terminal 회귀 evidence를 폐쇄했으며 9회 FAIL 뒤 최종 판정은 PASS다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_local_G06_0.log` | `code_review_local_G07_0.log` | FAIL | 구현과 대상 회귀 테스트가 없어 staged commit/release 계약을 구현했다. |
| `plan_local_G06_1.log` | `code_review_local_G07_1.log` | FAIL | partial confirm, attempt reservation, selected-attempt identity와 deterministic concurrency assertion을 보완했다. |
| `plan_local_G07_2.log` | `code_review_local_G08_2.log` | FAIL | stale/duplicate commit 방지, success-terminal gate와 exact named regression을 보완했다. |
| `plan_local_G07_3.log` | `code_review_local_G08_3.log` | FAIL | sink forward-state 보존, known-complete epoch와 callback barrier/order 검증을 보완했다. |
| `plan_local_G07_4.log` | `code_review_local_G08_4.log` | FAIL | operation-aware sink outcome과 confirmation/terminal/discard assertion을 보완했다. |
| `plan_local_G06_5.log` | `code_review_local_G07_5.log` | FAIL | terminal returned-state 단조 반영과 public confirmation/re-entry 경로를 보완했다. |
| `plan_local_G06_6.log` | `code_review_local_G07_6.log` | FAIL | reservation operation identity, terminal no-reentry와 실제 회귀 evidence를 보완했다. |
| `plan_local_G06_7.log` | `code_review_local_G07_7.log` | FAIL | reservation attempt identity, exact confirmation/cancel evidence와 명령 기록을 보완했다. |
| `plan_local_G06_8.log` | `code_review_local_G06_8.log` | FAIL | 위치 구별 suffix matrix, cancel hook snapshot과 검증 기록 일치를 보완했다. |
| `plan_local_G06_9.log` | `code_review_local_G06_9.log` | PASS | distinct confirmation identity, discard-before-cancel-before-terminal과 fresh evidence가 최종 통과했다. |

## 구현/정리 내용

- CommitBoundary가 attempt/generation/operation reservation을 검증하고 sink가 반환한 irreversible forward state를 오류와 함께 보존하도록 정리했다.
- response-start staging, 첫 safe release, selected-attempt replacement, post-open replay 거부와 single terminal 경계를 named regression으로 고정했다.
- StreamReleaser가 zero/partial/full sink progress를 exact token과 cursor에 confirm하고 success terminal은 confirmed epoch에만 허용하도록 검증했다.
- 위치가 구별되는 payload로 remaining suffix와 consumed epoch를 검증하고, cancel hook 시점의 pending/prepared invalidation과 `discard-verified → cancel → terminal` 순서를 고정했다.
- 리뷰 중 exact inventory의 합성 출력 표기와 package module 경로 오타를 실제 명령 의미에 맞게 정정했다.

## 최종 검증

- `command -v go && readlink -f "$(command -v go)" && go version && go env GOROOT` - PASS; `/config/.local/bin/go` → `/config/opt/go/bin/go`, `go1.26.2 linux/arm64`, GOROOT `/config/opt/go`.
- `gofmt -d packages/go/streamgate/stream_release_test.go` - PASS; 출력 없음.
- exact 8-test inventory 명령 - PASS; exit code 0, stdout 없음.
- `go test -race -count=20 ./packages/go/streamgate -run '^Test(CommitBoundary(PreservesReturnedStateAcrossSinkErrors|RejectsWrongOrMissingAttempt|SerializesConcurrentStartAndTerminal|RejectsPostOpenReplacement)|StreamReleaser(ConfirmsProgressEvenWhenSinkFails|SuppressesSuccessTerminalUntilConfirmation|RejectsReentrantCallbackWithoutDeadlock|FailPendingOrdersDiscardCancelTerminal))$'` - PASS; `ok iop/packages/go/streamgate`.
- `go test -count=1 -v ./packages/go/streamgate -run '^Test(CommitBoundary|StreamReleaser)'` - PASS; 리뷰 재실행 전체 stdout=`/tmp/iop-streamgate-review-review-api-9-review.log`.
- `go test -count=1 ./packages/go/streamgate` - PASS; `ok iop/packages/go/streamgate`.
- `go test -race -count=1 ./packages/go/streamgate` - PASS; race 없음.
- `go vet ./packages/go/streamgate` - PASS; 출력 없음.
- `make proto` - PASS; 생성물 추가 diff 없음.
- `go test -count=1 ./apps/edge/internal/transport ./apps/node/internal/transport` - BLOCKED; host GOROOT의 `/config/opt/go/src/crypto/internal/fips140cache` 누락으로 두 package가 setup 전에 exit code 1.
- forbidden-pattern, assertion inventory, `git diff --check`와 proto generated hygiene - PASS.

## 잔여 Nit

- 없음

## 후속 작업

- host `/config/opt/go` 설치를 복구한 뒤 Edge/Node transport unit을 재실행한다. 현재 test-only write-set의 동작 판정과 분리된 환경 복구 항목이다.
