patterns-established:
  - "Projection layer owns fallback normalization from raw snapshot fields"
  - "Partial payloads collapse to explicit MissingPartialData rendering state"

# Phase 03 Plan 02: Core Card Dashboard Summary

**Service-backed dashboard projection pipeline with deterministic stale and missing-data rendering semantics**

## Performance

- **Duration:** 6 min
- **Started:** 2026-02-28T04:22:00Z
- **Completed:** 2026-02-28T04:28:07Z
- **Tasks:** 3
- **Files modified:** 9

## Accomplishments
- Extended recipient snapshot contract with all card projection fields needed by the dashboard.
- Added app projection logic that maps snapshots into card view models with stale policy and fallback states.
- Added regression tests for normal, partial, stale, and missing-image scenarios.

## Task Commits

1. **Task 1: Extend service snapshot contract for card projection needs** - `f2ae3e4` (feat)
2. **Task 2: Implement dashboard projection and thumbnail fallback policy** - `bac94cd` (feat)
3. **Task 3: Bind projection fields into Slint card components with edge-state rendering** - `2ebf63c` (test)

## Files Created/Modified
- `crates/service/src/api/recipients.rs` - Card-focused snapshot fields and defaults.
- `crates/app/src/service_client.rs` - Dashboard snapshot retrieval client contract.
- `crates/app/src/dashboard/projection.rs` - Snapshot-to-view-model mapping + stale threshold logic.
- `crates/app/tests/dashboard_projection_tests.rs` - Projection regression suite.

## Decisions Made
- Kept snapshot shape additive to avoid breaking existing service callers.
- Made projection the single owner of fallback normalization so UI bindings stay simple.

## Deviations from Plan

None - plan executed exactly as written.

---

**Total deviations:** 0 auto-fixed (none)
**Impact on plan:** None.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
Ready for refresh interaction wiring and shared command dispatch across per-card, refresh-all, and F5 triggers.
