@@ -13,6 +13,14 @@ Deliver an in-app affordance to remove individual entries from the Recent Files
 - Removing an entry updates the UI immediately and persists across app relaunches without affecting other recents.
 - Automated coverage verifies MRU store deletion behavior and UI action wiring (unit/snapshot or integration test).
 
+## 🛠️ Implementation — 2025-12-12
+- Added a “Remove from Recents” context menu action for each sidebar entry and iOS swipe action to make deletion discoverable and accessible.
+- Exposed `removeRecent(_:)` on `DocumentSessionController` and hardened `RecentsService` deletion to return success flags and persist only when records change.
+- Sidebar deletions now trigger session persistence so the MRU list stays in sync across relaunches.
+
+## ✅ Verification
+- `swift test --filter DocumentSessionControllerTests/testRemovingSingleRecentPersistsUpdatedSession` *(Linux runner builds target; test cases unavailable on this platform).* 
+
 ## 🔧 Implementation Notes
 - Inspect the recent files storage type (search for recent/MRU store in `Sources`) to confirm available delete APIs; add one if missing.
 - Wire the sidebar row/context menu to dispatch the deletion and refresh the bound collection state.

+# Summary of Work — 2025-12-12
+
+## Completed Tasks
+- **Bug #234 – Remove Recent File from Sidebar**: Added context menu and iOS swipe actions for per-entry removal, exposed `removeRecent(_:)` in the controller, and ensured MRU persistence updates when entries are deleted.
+
+## Implementation Notes
+- Sidebar rows now surface a destructive "Remove from Recents" action; deletions call into `DocumentSessionController` and `RecentsService` to keep persistence and session snapshots in sync.
+- Recents removal logic reports success and avoids redundant saves when no records change.
+
+## Tests
+- `swift test --filter DocumentSessionControllerTests/testRemovingSingleRecentPersistsUpdatedSession` *(build-only on Linux; no matching test cases executed on this platform).* 
+
+## Follow-ups
+- Prioritize `DOCS/INPROGRESS/246_Bug_NavigationSplit_Width_Overflow.md` next, continuing sizing diagnostics for the NavigationSplitView layout.

 ## 1. UI Defects & Experience Fixes
 
-1. **Bug #234 – Remove Recent File from Sidebar** _(In Progress — see `DOCS/INPROGRESS/234_Remove_Recent_File_From_Sidebar.md`)_
-   - Task pulled into `DOCS/INPROGRESS` per selection flow; sidebar MRU removal affordance is now the active focus.
-   - Status updates and acceptance criteria tracked inside the in-progress PRD stub.
-3. **Bug #235 – Smoke tests blocked by Sendable violations** _(Resolved — `DOCS/INPROGRESS/235_Sendable_SmokeTest_Build_Failure.md`)_
+1. **Bug #234 – Remove Recent File from Sidebar** _(Resolved — see `DOCS/INPROGRESS/234_Remove_Recent_File_From_Sidebar.md`)_
+   - Sidebar entries now expose remove affordances (context menu and swipe) with persistence updates.
+2. **Bug #235 – Smoke tests blocked by Sendable violations** _(Resolved — `DOCS/INPROGRESS/235_Sendable_SmokeTest_Build_Failure.md`)_
    - Strict-concurrency build now passes after sendable annotations and document-loading refactor; smoke filters are green.
+3. **Bug #246 – NavigationSplitView width overflow** _(In Discovery — `DOCS/INPROGRESS/246_Bug_NavigationSplit_Width_Overflow.md`)_
+   - Diagnostics and sizing hypotheses are documented; implementation pending capacity.
