## 요약

Dart TCP/WS 1MB payload guard review loop completed after 2 reviews; final verdict PASS.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_local_G05_0.log` | `code_review_local_G05_0.log` | FAIL | quick baseline comparison did not include Dart 1MB payload rows, and WS 1MB test lacked tail verification. |
| `plan_local_G06_1.log` | `code_review_local_G06_1.log` | PASS | Added WS 1MB tail assertion and recorded focused Dart TCP/WS 1MB baseline comparison evidence. |

## 구현/정리 내용

- Added `WS 1MB payload roundtrip` coverage in `dart/test/socket_test.dart` using an isolated dynamic WebSocket request server port.
- Added response tail verification so the WS 1MB test catches truncation or tail corruption, not just length/prefix.
- Recorded focused Dart TCP/WS `payload=1MB` baseline comparison evidence from full payload stress records.
- Cleaned duplicated review-stub residue in `CODE_REVIEW-local-G06.md` before archiving; no source behavior was changed by that cleanup.

## 최종 검증

- `dart format --output=none --set-exit-if-changed dart/test/socket_test.dart` - PASS; `Formatted 1 file (0 changed)`.
- `cd dart && dart test test/socket_test.dart` - PASS; `00:17 +43: All tests passed!`.
- `bash agent-ops/skills/project/run-proto-socket-test-matrix/scripts/run_stress.sh --full --lang dart --transport tcp,ws --profile payload` - PASS; `DONE dart: PASS (rows=6 skips=0 required_skips=0 violations=0)`, record=`agent-test/runs/20260614-112932-proto-socket-stress-full.md`.
- focused Dart 1MB comparator with `baseline=agent-test/runs/20260613-141506-proto-socket-performance-full.md` and `current=agent-test/runs/20260614-112932-proto-socket-stress-full.md` - PASS; tcp/ws 1MB rows were found and compared.
