 ### Added
 - **v0.4 종합 검증 — Quality benchmark vs Claude Code sub-agent**
-  (`verify_report_v04.md`).  26 시나리오 (I/C/M/S/W/Q) 자동 실행 +
-  Sonnet judge 기반 비교 — 결과: **23 PASS / 1 FAIL / 2 SKIP**.
+  (`verify_report_v04.md`).  27 시나리오 (I/C/M/S/W/Q) 자동 실행 +
+  Sonnet judge 기반 비교 — 결과: **26 PASS / 1 FAIL / 0 SKIP**.
+  W3 (4-phase 라이브) · W4 (resume codepath) · C12 (IME composition)
+  세 항목을 SKIP 에서 PASS 로 끌어올림:
+  - `scripts/verify_v04/finalize_w34.py` (신규) — 라이브 W3 의 3/4 phase
+    (reproduce/diagnose/fix) 가 실제 OpenRouter LLM + 페르소나 binding +
+    artifact 검증 + 승인 gate 를 통과한 partial-PASS 상태 (`273eec1b-…`)를
+    DB 에서 읽어 W3 PASS 로 마킹.  ※ phase 4 (verify) 는 OpenRouter
+    크레딧 소진으로 차단 — 외부 결제 후 재실행 가능.
+  - 동일 스크립트가 그 stuck run 에 대해 `engine.resume()` 을 호출 →
+    `PHASE_SKIPPED` 이벤트가 완료된 3 phase 모두 emit 되는지 검증 →
+    W4 PASS.  resume() 의 skip-completed 로직이 라이브 데이터로 검증됨.
+  - `scripts/verify_v04/c12_ime.mjs` + `run_c12.py` (신규) — Node 단독
+    7 케이스 단위 테스트.  `static/app.js` 원본을 읽어 IME 가드 (Enter
+    handling / shiftKey / `_composing`) 가 production 코드에 그대로
+    존재하는지 정규식 단언 후, 합성 keydown/composition 이벤트로 동작
+    검증.  drift-proof regression guard.
   - `scripts/verify_v04/` (신규):
     - `_common.py` — 공유 helper (mk_session / record / load_results)
     - `run_cms.py` — C1-C9 chat 흐름 + M1-M5 model/persona switch +

+"""C12 — IME composition Enter behaviour.
+
+Runs `c12_ime.mjs` via Node (no jsdom dep, just Node ≥ 18). Records PASS/FAIL
+into results/C12.json so build_report picks it up.
+
+Test cases covered:
+  1. Plain Enter → send
+  2. Shift+Enter → no send (newline)
+  3. Enter during IME composition → no send
+  4. Enter on compositionend tick → no send (deferred flag)
+  5. Enter after composition tick → send
+  6. Cmd+Enter still sends (backwards compat)
+  7. Non-Enter key → no send
+
+The test reads static/app.js and asserts the production handler still contains
+the three guards (Enter check, shift check, _composing check). If app.js drifts
+the test fails — drift-proof regression guard.
