Migrate app code into canonical feature slices, add phone-only AI digest scheduling and review, wire local notification/background task support, and cover the flow with tests.
Signals Slice
This slice owns the derived relationship signal feed.
Use it for product logic that turns stored context into suggestions, signals, or future recommendation hooks.
Current signal sources:
- local synthesized follow-through suggestions derived from people, reminders, ideas, dates, and preference signals
- optional LLM-generated signals when configured
- backend feed items when running against a real gateway or when no better local feed exists
