# Phase 03 Plan 01: Core Card Dashboard Summary

**Dashboard card-grid shell with hierarchy-safe card fields and deterministic missing-data fallbacks**

## Performance

- **Duration:** 11 min
- **Started:** 2026-02-28T04:10:00Z
- **Completed:** 2026-02-28T04:21:34Z
- **Tasks:** 3
- **Files modified:** 8

## Accomplishments
- Added the dashboard Slint artifact with a dense but readable three-column card-grid baseline.
- Introduced dashboard view-model/state contracts that preserve recipient/status/item/note hierarchy and explicit fallback states.
- Added regression coverage for layout baseline, single-line note truncation, and missing image/note handling.

## Task Commits

1. **Task 1: Add Slint dashboard shell and card-grid component** - `b3885ad` (feat)
2. **Task 2: Define card view-model and rendering state contracts** - `40cc854` (feat)
3. **Task 3: Add layout and hierarchy regression coverage** - `cfd2241` (test)

## Files Created/Modified
- `crates/app/ui/dashboard.slint` - Dashboard shell and card-grid artifact.
- `crates/app/src/dashboard/view_model.rs` - Card field ordering and note/image fallback helpers.
- `crates/app/src/dashboard/state.rs` - Missing-data, refresh, and selection state enums.
- `crates/app/src/dashboard/mod.rs` - Dashboard module exports and card container.
- `crates/app/tests/dashboard_layout_tests.rs` - Regression tests for hierarchy/layout/fallback invariants.

## Decisions Made
- Kept dashboard contracts UI-first (not raw service payload shape) to avoid coupling before projection wiring.
- Encoded missing-data behavior as explicit enums so rendering behavior is deterministic and testable.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Deferred external Slint runtime dependency installation**
- **Found during:** Task 1 (dashboard shell setup)
- **Issue:** Project currently compiles without external UI runtime crate wiring and no existing Slint build pipeline.
- **Fix:** Added `.slint` UI artifact plus Rust-side dashboard contracts/tests first; runtime binding is completed in subsequent wiring plans.
- **Files modified:** crates/app/ui/dashboard.slint, crates/app/src/main.rs, crates/app/Cargo.toml
- **Verification:** `cargo test -p app dashboard_layout -- --nocapture`
- **Committed in:** b3885ad (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** No functional regression; established UI baseline artifacts and contracts required for Phase 3 data/refresh wiring.

## Issues Encountered
None

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

## Next Phase Readiness
Ready for 03-02 projection/data wiring with stable card contracts and fallback semantics already locked by tests.
