 개발 참고: Claw Code 동등성 작업 추적 문서

+- `claw-code` 대비 AX Agent 추정 진척율 기준선을 문서에 남겼습니다. 현재 기준은 핵심 엔진 `82%`, 채팅 메인 UI `68%`, Cowork/Code 상태 UX `63%`, 내부 설정 연결 `88%`, 전체 AX Agent 동등 품질 `74%`입니다.
+- 메인 핵심 엔진 로직에 직접 영향을 주는 설정은 최소화 원칙으로 다시 검토하기 시작했습니다. 이미 실질 선택지가 사라진 `계획 모드` 계열은 사용자 노출을 더 줄였고, 남은 엔진성 설정은 개발자 탭 중심으로 계속 정리합니다.
+- 메시지 행과 좌측 대화 목록도 `claw-code` 방향으로 다시 단순화했습니다. 사용자/assistant 버블의 패딩, 라운드, 메타 텍스트를 줄였고, 대화 목록의 실행 상태도 배지 카드보다 얇은 텍스트 요약 중심으로 바꿔 읽는 축이 먼저 보이도록 눌렀습니다.

 - `document_plan` 후속 실행 분기를 `claw-code` 기준으로 다시 보강했습니다. 이제 문서 플래너 출력에서 body 골격과 즉시 실행 지시를 깨진 문자열 비교에 의존하지 않고 안정적으로 추출해, `html_create / document_assemble / docx_create / markdown_create` 후속 호출 유도가 실제로 이어집니다.
 - 코워크 문서형 작업은 설정이 `planMode=off`여도 내부적으로 `always` 플랜 경로를 타도록 보정했습니다. 그래서 문서/보고서/제안서 요청은 먼저 계획을 세우고, 그 계획을 바탕으로 실제 문서 생성 단계까지 이어가도록 정리했습니다.

 # AX Copilot - 媛쒕컻 臾몄꽌
 
+- Document update: 2026-04-05 16:55 (KST) - Recorded the current `claw-code` parity estimate for AX Agent: core execution engine `82%`, main chat UI `68%`, Cowork/Code status UX `63%`, internal settings linkage `88%`, overall AX Agent parity `74%`.
+- Document update: 2026-04-05 16:55 (KST) - Added an engine-settings review rule for ongoing cleanup: settings that materially alter the main execution route should be minimized, kept developer-only when necessary, or removed from user-facing surfaces when they no longer represent real runtime choices. Plan-mode remnants were reduced further as part of this pass.
+- Document update: 2026-04-05 16:55 (KST) - Simplified AX Agent message rows and sidebar conversation items toward the `claw-code` reading model. Message bubbles now use tighter padding/radius/meta text, and conversation rows now prefer lightweight running/failure summary text over heavier success/failure badge cards.
 - Document update: 2026-04-05 16:02 (KST) - Fixed the Cowork document execution handoff around `document_plan`. The loop no longer depends on broken localized marker strings to detect the scaffold/body block or the immediate-next-step hint; it now extracts body markers robustly and resolves the correct follow-up tool (`html_create`, `document_assemble`, `docx_create`, `markdown_create`) before re-prompting the model.
 - Document update: 2026-04-05 16:02 (KST) - Added `ResolveEffectivePlanMode(...)` so Cowork document/content tasks automatically use the `always` plan path even when the persisted plan mode is `off`. This brings Cowork closer to the `claw-code` expectation of plan-first execution for document-heavy work.
 - Document update: 2026-04-05 16:02 (KST) - Strengthened `BuildCoworkSystemPrompt()` so document/report/proposal/manual requests must produce an execution plan first and are not considered complete until a real output file path has been created or updated.

 - Updated: 2026-04-05 15:34 (KST)
 - Rebased the AX Agent improvement plan on actual `claw-code` runtime files instead of earlier AX snapshots. The reference spine is now `src/bootstrap/state.ts -> src/bridge/initReplBridge.ts -> src/bridge/sessionRunner.ts -> src/screens/REPL.tsx -> src/components/Messages.tsx -> src/components/StatusLine.tsx`.
 - AX Agent work should follow that same quality order: state first, execution second, render last. UI-only fixes that bypass state/execution should be treated as temporary.
+- Updated: 2026-04-05 16:55 (KST)
+- Current estimated parity vs `claw-code`: core execution engine `82%`, main chat UI `68%`, Cowork/Code status UX `63%`, internal settings linkage `88%`, overall AX Agent `74%`.
+- Engine-affecting settings should be handled conservatively during parity work. If a setting changes the main execution route, approval flow, or recovery behavior without representing a stable real-world user choice, it should be moved to developer-only UI or removed from user-facing surfaces.
 
 ## Preserved History (Summary)
 - Core loop guards and post-tool verification gates are already partially implemented.
