+## Latest Milestone (2026-02-15): Direct Entity Repair Forms From Sync
+
+Implemented deep-link repair forms for rejected sync items:
+
+- Updated `lib/features/sync/sync_view.dart`:
+  - `Open Related Screen` now routes into dedicated entity-specific repair
+    forms, not just general list screens
+  - supported entity repair forms:
+    - `person`
+    - `capture`
+    - `giftIdea`/`eventIdea`
+    - `reminderRule`
+  - each form updates local state via `LocalRepository` directly
+  - focus banner keeps exact `entityType:entityId` context with copy action
+
+Validation for this milestone:
+
+- `flutter analyze` -> pass
+- `flutter test` -> pass

 ## Latest Milestone (2026-02-15): Notification Tap Routing
 
 Implemented initial in-app routing for reminder notification taps:

    - permission UX implemented in settings.
    - notification tap routing implemented for reminder screen handoff.
 2. Conflict resolution UX:
-   - reject/requeue + payload inspect + related-screen navigation implemented.
+   - reject/requeue + payload inspect + direct entity repair forms implemented.
-   - future enhancement: deep-link directly to specific entity edit form.
+   - future enhancement: auto-select and highlight the exact row in main feature
+     screens after save.
 3. Sync trigger maturity:
    - implemented via reachability gating; future improvement is explicit OS
      connectivity event subscription.
