 - 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.
