## 요약

Client proto-socket diagnostics follow-up closed after 3 review loops; final verdict PASS.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | FAIL | stale diagnostics cleanup, task service diagnostics coverage, Flutter verification evidence required |
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | FAIL | failed reconnect regression was claimed but missing from actual lifecycle tests |
| `plan_cloud_G07_2.log` | `code_review_cloud_G07_2.log` | PASS | failed reconnect stale diagnostics regression added and verification evidence aligned |

## 구현/정리 내용

- `ProtoSocketLifecycle` reset transitions clear connection-scoped diagnostics on reconnect start, connect failure, and disconnect while preserving protocol version.
- Lifecycle tests now cover disconnect cleanup, reconnect start cleanup, and failed reconnect cleanup after prior envelope diagnostics.
- Task service tests verify lifecycle diagnostics capture for success meta and error envelope code without changing `ProtoSocketTaskService` production API.
- Widget tests were stabilized around bounded pumps and teardown timing for the diagnostics surface.
- Review evidence was corrected to match the actual tests and recorded remote Flutter verification output.

## 최종 검증

- `cd apps/client && flutter test test/integrations/proto_socket_lifecycle_test.dart` - PASS; remote runner reported `00:00 +12: All tests passed!`.
- `cd apps/client && flutter test test/integrations/proto_socket_lifecycle_test.dart test/integrations/proto_socket_task_service_test.dart test/widget_test.dart` - PASS; remote runner reported `00:01 +36: All tests passed!`.
- `cd apps/client && flutter test` - PASS; remote runner reported `00:01 +47: All tests passed!`.
- `cd apps/client && flutter analyze --no-fatal-infos` - PASS; remote runner exited 0 with the known 13 `avoid_print` info findings in `mattermost_auth_service.dart`.
