   - timeline 조립 helper를 [ChatWindow.TimelinePresentation.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.TimelinePresentation.cs) 로 분리했다. `RenderMessages()`가 직접 처리하던 visible 메시지 필터링, execution event 노출 집계, timestamp/order 기반 timeline action 조립을 helper 메서드로 옮겨 메인 렌더 루프를 더 단순화했다.

   - timeline presentation 정리를 이어서 진행했다. [ChatWindow.TimelinePresentation.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.TimelinePresentation.cs) 에 `CreateTimelineLoadMoreCard`, `ToAgentEvent`, `IsCompactionMetaMessage`, `CreateCompactionMetaCard`까지 옮겨 `RenderMessages()` 주변의 timeline helper를 한 파일로 모았다.

+  - 대화 목록 관리 interaction을 [ChatWindow.ConversationManagementPresentation.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.ConversationManagementPresentation.cs) 로 분리했다. 제목 인라인 편집 `EnterTitleEditMode(...)` 와 대화 메뉴 `ShowConversationMenu(...)`가 메인 [ChatWindow.xaml.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Views/ChatWindow.xaml.cs) 밖으로 이동해, 고정/이름 변경/카테고리 변경/삭제 같은 목록 관리 UI 책임도 별도 presentation surface에서 다루게 정리했다.
+  - 이 단계까지 완료된 구조 개선은 상태선/권한/도구 결과 카탈로그화, inline ask/plan 분리, footer/Git/preset/list/message/timeline 분리, 그리고 conversation management 분리까지다. 이제 남은 건 큰 구조 개선이 아니라 개별 surface polish와 후속 UX 고도화 수준이다.

 - Document update: 2026-04-06 10:36 (KST) - This keeps `RenderMessages()` closer to a simple orchestration loop and reduces mixed responsibilities inside the main chat window file.
 - Document update: 2026-04-06 10:44 (KST) - Continued timeline presentation cleanup by moving `CreateTimelineLoadMoreCard`, `ToAgentEvent`, `IsCompactionMetaMessage`, and `CreateCompactionMetaCard` into `ChatWindow.TimelinePresentation.cs`.
 - Document update: 2026-04-06 10:44 (KST) - This consolidates timeline-related helpers in one place and leaves the main chat window file with less transcript-specific rendering logic around `RenderMessages()`.
+- Document update: 2026-04-06 10:56 (KST) - Split conversation-management interactions out of `ChatWindow.xaml.cs` into `ChatWindow.ConversationManagementPresentation.cs`. Inline title editing and the conversation action popup (pin/unpin, rename, category change, delete) now live in a dedicated presentation partial.
+- Document update: 2026-04-06 10:56 (KST) - With this pass, the remaining large structure-improvement track is effectively complete; follow-up work is now mostly UX polish and surface-level tuning rather than further decomposition of the main chat window orchestration file.
