### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-----------|-------------|--------|----------|
| DISC-01 | 06-01, 06-02 | Instant fuzzy search begins when user types any letter or space | SATISFIED | filter_cards_by_search implemented and tested (34 tests), SearchBar component with auto-focus via character-pressed callback, search-changed wired to filter pipeline |
| DISC-04 | 06-01, 06-03 | By Recipient mode starts with recipient option grid then transitions to filtered card view | SATISFIED | extract_recipient_tiles implemented and tested, RecipientGrid component with A-Z section headers, tile-clicked transitions to FilteredCards, breadcrumb-back returns to grid |
| DISC-05 | 06-01, 06-03 | By Product Shipped mode starts with product option grid then transitions to filtered card view | SATISFIED | extract_product_tiles implemented and tested, ProductGrid component with image hints, tile-clicked and breadcrumb-back wired |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| search-bar.slint | 36 | Comment "Search icon placeholder" | Info | Visual comment only, not a code stub -- magnifying glass emoji is used |
| main.rs | 563-574 | card_save_note, card_add_item, card_remove_item, card_summary are println!() stubs | Info | Pre-existing from earlier phases, not Phase 6 scope |

No blocker or warning-level anti-patterns found in Phase 6 artifacts.

### Human Verification Required

### 1. Search Auto-Focus and Filtering

**Test:** Launch app with `cargo run -p app`. Type any letter while no input is focused.
**Expected:** Search bar auto-focuses, typed character appears, cards filter in-place, result count badge shows.
**Why human:** Keyboard interaction and visual rendering require running the app.

### 2. Status Chip Toggling

**Test:** Click status chips in the bottom bar.
**Expected:** Chips highlight with accent blue (#4a7cff), cards filter by selected statuses (OR logic). Multiple chips can be selected.
**Why human:** Visual feedback and interactive toggle behavior.

### 3. Recipient Option Grid

**Test:** Switch to Recipient mode (press Down arrow twice from default).
**Expected:** Alphabetical tile grid with A-Z section headers. Click a name tile -- filtered card view with breadcrumb back-arrow. Press Esc -- returns to tile grid.
**Why human:** Grid layout, section headers, and transition flow need visual verification.

### 4. Product Option Grid

**Test:** Switch to Product Shipped mode (press Down arrow three times from default).
**Expected:** Product tile grid with names. Click a product tile -- filtered card view with breadcrumb. Esc returns to tiles.
**Why human:** Tile layout and image placeholder rendering.

### 5. Three-Layer Esc Behavior

**Test:** Type a search query, then press Esc three times.
**Expected:** 1st Esc: search bar defocuses (text stays, cards stay filtered). 2nd Esc: search text clears, all cards shown. 3rd Esc: mode home (ClearFiltersAndScrollTop toast). Double-Esc from mode home resets to default.
**Why human:** Timing-sensitive keyboard interaction sequence.

### 6. Per-Mode State Persistence

**Test:** Type a search in Recipient mode. Switch to Status Updated mode. Switch back to Recipient mode.
**Expected:** Search text is restored. Similarly, chip selections persist per mode independently.
**Why human:** Multi-step stateful interaction.

### Gaps Summary

No automated gaps found. All 8 observable truths verified through code inspection, 73 passing tests, successful compilation, and wiring analysis. All 4 requirement IDs (DISC-01, DISC-04, DISC-05, DISC-06) are satisfied with implementation evidence.

Human verification is needed to confirm the visual and interactive experience works correctly at runtime. The code analysis shows all components are substantive (not stubs), all callbacks are wired to real filter/state logic, and the filter pipeline composes correctly.
