# Phase 6 Plan 02: Search Bar and Chip Bar UI Summary

**SearchBar and ChipBar Slint components with instant search filtering, status chip toggling, character-key auto-focus, and per-mode state persistence**

## Performance

- **Duration:** 8 min
- **Started:** 2026-03-08T04:49:49Z
- **Completed:** 2026-03-08T04:58:00Z
- **Tasks:** 2
- **Files modified:** 8

## Accomplishments
- Search bar always visible above card grid, auto-focuses when user types any character
- Status chip bar with 6 toggleable chips (Not Shipped, Label Created, In Transit, Delivered, Return In Transit, Returned) filters cards by OR/union logic
- Per-mode state persistence: search text and chip selections survive mode switches independently
- Three-layer Esc: defocus search -> clear search -> mode home, without triggering double-Esc reset
- 73 unit tests pass covering filter functions, Esc layering, and per-mode state

## Task Commits

Each task was committed atomically:

1. **Task 1: Create SearchBar and ChipBar Slint components** - `1cb4fc4` (feat)
2. **Task 2: Integrate search bar, chip bar, and character-key forwarding into dashboard** - `a88cbbf` (feat)

## Files Created/Modified
- `crates/app/ui/search-bar.slint` - SearchBar component with text binding, result count badge, focus-input function
- `crates/app/ui/chip-bar.slint` - ChipBar component with toggleable status chips in horizontal Flickable
- `crates/app/ui/option-grid.slint` - RecipientGrid and ProductGrid components (scaffolding for Plan 03)
- `crates/app/ui/dashboard.slint` - Updated layout: search bar in title bar, chip bar at bottom, conditional content areas
- `crates/app/src/main.rs` - Wired search-changed, chip-toggled, character-pressed callbacks with filter pipeline
- `crates/app/src/dashboard/discovery.rs` - Added ModeState, ModeViewState, extended EscAction, filter functions, tile extraction
- `crates/app/src/dashboard/mod.rs` - Added DashboardRuntime methods for search, filters, and extended Esc
- `crates/app/src/dashboard/projection.rs` - Added filter_cards_by_search and filter_cards_by_status re-exports

## Decisions Made
- Implemented Plan 01's Rust backend inline because it was a blocking dependency (Plan 02 depends on 06-01 which hadn't been executed yet). This includes filter_cards_by_search, filter_cards_by_status, ModeState, extended EscAction with DefocusSearch/ClearSearch/ReturnToOptionGrid, handle_esc_layered, extract_recipient_tiles, extract_product_tiles.
- Character-key forwarding uses a Slint callback to main.rs which appends the character to search text and triggers filtering, since Slint TextInput.focus() may not forward the initial keypress.
- Filter pipeline converts seed CardData to DashboardCardViewModel for Rust filtering, then maps survivors back to CardData for Slint display.
- Accepted linter-generated option-grid.slint and expanded dashboard.slint with breadcrumb/grid-switching layout as scaffolding for Plan 03.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Implemented Plan 01 Rust backend as blocking dependency**
- **Found during:** Task 1 pre-analysis
- **Issue:** Plan 02 depends on Plan 01 (filter functions, ModeState, EscAction extensions) which had not been executed
- **Fix:** Added all Plan 01 backend code: filter_cards_by_search, filter_cards_by_status, ModeState, ModeViewState, extended EscAction enum, handle_esc_layered, extract_recipient_tiles, extract_product_tiles, DashboardRuntime methods, and 22 new tests
- **Files modified:** discovery.rs, mod.rs, projection.rs
- **Verification:** All 73 dashboard tests pass
- **Committed in:** 1cb4fc4 (Task 1 commit)

**2. [Rule 3 - Blocking] Accepted linter-generated option-grid.slint scaffolding**
- **Found during:** Task 2
- **Issue:** Linter auto-generated option-grid.slint and expanded dashboard.slint with RecipientGrid/ProductGrid imports and breadcrumb layout
- **Fix:** Included the scaffolding since the linter persisted changes. Components are unused but ready for Plan 03.
- **Files modified:** option-grid.slint, dashboard.slint
- **Verification:** Build compiles cleanly with no errors
- **Committed in:** a88cbbf (Task 2 commit)

---

**Total deviations:** 2 auto-fixed (2 blocking)
**Impact on plan:** Both auto-fixes necessary for task completion. Plan 01 backend was required for UI wiring. Option grid scaffolding is forward-compatible with Plan 03.

## Issues Encountered
None beyond the blocking dependency on Plan 01.

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

## Next Phase Readiness
- Search bar and chip bar fully functional with filter pipeline
- Option grid Slint components scaffolded, ready for Plan 03 to wire tile-clicked and breadcrumb-back
- Per-mode state persistence and three-layer Esc complete
- All 73 dashboard tests pass

## Self-Check: PASSED

- All 8 key files verified present on disk
- Commit 1cb4fc4 (Task 1) verified in git log
- Commit a88cbbf (Task 2) verified in git log
- Build compiles with zero errors
- 73 dashboard tests pass
