+## Latest Milestone (2026-02-22): Preference Review UI (People + Graph Insights)
+
+Exposed the new chat-derived preference signals in the main person detail
+surfaces and added a user review loop to confirm or dismiss inferred context.
+
+- `lib/features/people/people_view.dart`
+  - added `Chat-derived preferences` section to the People detail workspace
+  - shows inferred/confirmed/dismissed signals sorted by status/confidence
+  - per-signal actions:
+    - `Why?` (evidence preview bottom sheet)
+    - `Confirm`
+    - `Dismiss`
+  - evidence preview includes:
+    - signal metadata (category/polarity/confidence)
+    - evidence snippets extracted from shared chat messages
+    - source app list
+  - added explicit `Close` action in evidence sheet (better UX + testability)
+
+- `lib/features/dashboard/dashboard_view.dart`
+  - added matching `Chat-derived preferences` section to graph long-press
+    `Person Insights` page
+  - same confirm/dismiss/why review flow and evidence preview
+  - keeps profile review experience aligned between People page and graph flow
+
+- `test/features/dashboard/dashboard_graph_interactions_test.dart`
+  - extended graph interaction test to:
+    - seed an inferred preference signal
+    - assert section renders in `Person Insights`
+    - open `Why?` evidence preview
+    - confirm signal and verify local status updates to `confirmed`
+
+- Validation
+  - `flutter analyze` -> pass
+  - `flutter test` -> pass
