# Dependency graph
requires:
  - phase: 09-item-note-crud-wiring
    provides: on_lookup_item_selected and on_lookup_create_confirmed callbacks, item_summary field on CardData
provides:
  - Multi-item accumulation via pipe-separated item_summary string
  - word-wrap on card item-summary Text element for multi-item display
affects: [ui, item-management]

# Tech tracking
tech-stack:
  added: []
  patterns: [Pipe-separated delimited string for multi-value single-field accumulation]

key-files:
  created: []
  modified:
    - crates/app/src/main.rs
    - crates/app/ui/card.slint

key-decisions:
  - "Pipe-separated (' | ') delimited string for multi-item display preserves existing item_summary pipeline (filter/sort/projection) without structural refactor"
  - "Card-level remove clears all items (not per-item); acceptable for v1.0 since UI has one remove button for the whole item area"

patterns-established:
  - "Append-not-overwrite pattern: check current.is_empty() before deciding set vs format!('{} | {}', current, new)"

# Phase 9 Plan 04: Item Append (Multi-Item) Summary

**Pipe-separated append logic for item_summary field in both lookup callbacks, with word-wrap on card Text for multi-item display**

## Performance

- **Duration:** ~5 min
- **Started:** 2026-03-20T07:10:00Z
- **Completed:** 2026-03-20T07:15:00Z
- **Tasks:** 1
- **Files modified:** 2

## Accomplishments
- `on_lookup_item_selected` appends new item to `item_summary` with ` | ` separator instead of overwriting
- `on_lookup_create_confirmed` applies same append pattern in both code paths (with Shopify URL and without)
- `card.slint` item-summary Text element gains `wrap: word-wrap` for readable multi-item display

## Task Commits

Each task was committed atomically:

1. **Task 1: Convert item add to append and update card UI for multi-item display** - `f12b861` (feat)

**Plan metadata:** (docs commit — see below)

## Files Created/Modified
- `crates/app/src/main.rs` - Three append-logic changes in on_lookup_item_selected and on_lookup_create_confirmed
- `crates/app/ui/card.slint` - Added `wrap: word-wrap` to item-summary Text element

## Decisions Made
- Used ` | ` (space-pipe-space) as delimiter: visually clear and unlikely to appear in product names
- Kept `apply_optimistic_item_remove` as-is (clears all items); card-level remove is v1.0 acceptable behavior

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- UAT Test 6 fix complete: adding a second item from the lookup modal appends "Item A | Item B" instead of replacing Item A
- All phase 09 gap-closure plans complete; project is ready for final UAT validation pass
