## 요약

Client integration boundary 표준화 작업을 2회 리뷰 루프로 완료했다. 최종 판정은 PASS다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | WARN | README Mattermost host 책임 문구가 adapter/interface 경계와 충돌해 follow-up 필요 |
| `plan_local_G04_1.log` | `code_review_local_G04_1.log` | PASS | README 문구를 `MattermostPushClient`/`MattermostPushPluginClient` 경계와 일치시킴 |

## 구현/정리 내용

- proto-socket local Dart dependency, endpoint config, lifecycle facade, focused tests를 추가했다.
- Mattermost push plugin singleton 접근을 production adapter로 격리하고 host integration/auth handoff 경계를 정리했다.
- contracts compatibility note와 client README의 integration boundary 설명을 갱신했다.
- follow-up에서 README의 Mattermost host authentication 책임 문구를 adapter/interface 경계와 일치시켰다.

## 최종 검증

- `cd apps/client && flutter pub get` - PASS; dependency resolution completed.
- `cd apps/client && dart format --set-exit-if-changed lib test` - PASS; 16 files formatted, 0 changed.
- `cd apps/client && flutter test` - PASS; all tests passed.
- `cd apps/client && flutter analyze --no-fatal-infos` - PASS; exit 0 with existing `avoid_print` info only.
- `rg --sort path -n "MattermostPushPlugin.instance" apps/client/lib apps/client/test` - PASS; production singleton access remains isolated to the adapter file.
- `rg --sort path -n "Mattermost Authentication|MattermostPushPlugin.instance|MattermostPushClient|MattermostPushPluginClient" apps/client/README.md apps/client/lib/src/integrations/mattermost` - PASS; README and source show the adapter/interface boundary.
- `! rg --sort path -n 'by calling `MattermostPushPlugin.instance' apps/client/README.md` - PASS; stale direct-call wording is absent.
