# Phase 1: Bill Entry & Assignment Verification Report
**Phase Goal:** Enable users to add people, add items with prices, and assign items to people (single or shared)
**Verified:** 2026-03-12T03:19:00Z
**Status:** passed
**Re-verification:** No - initial verification
## Goal Achievement
### Observable Truths
| # | Truth | Status | Evidence |
| --- | ----- | ------ | -------- |
| 1 | User can add people to the bill by entering their names (PEOPLE-01) | VERIFIED | PersonForm.jsx imports store, calls addPerson(), clears on success, shows errors |
| 2 | User can add items with name and price to the bill (PEOPLE-02) | VERIFIED | ItemForm.jsx imports store, calls addItem(), clears on success, shows errors |
| 3 | User can assign any item to one or more specific people (PEOPLE-03) | VERIFIED | ItemAssign.jsx uses getAssignedPeople(), setAssignment() for single/multi select |
| 4 | User can mark an item as "shared" to split it across selected people (PEOPLE-04) | VERIFIED | ItemAssign.jsx checkbox UI allows multiple selection, setAssignment accepts array |
**Score:** 4/4 truths verified
### Required Artifacts

| `src/components/items/ItemsList.jsx` | Display list of items | VERIFIED | Reads store.items.value, uses formatCurrency, includes ItemAssign |
| `src/components/items/ItemAssign.jsx` | Multi-select UI for assignment | VERIFIED | Checkboxes for each person, togglePerson calls setAssignment |
| `src/app.jsx` | Main app component | VERIFIED | Imports and renders all Person and Item components |
| `vitest.config.js` | Test configuration | VERIFIED | Vitest with jsdom, globals enabled, includes tests/**/*.test.js |
| `tests/billStore.test.js` | Test stubs for PEOPLE-01-04 | VERIFIED | 10 tests covering addPerson, addItem, setAssignment, getAssignedPeople |
| `tests/currency.test.js` | Test stubs for currency utils | VERIFIED | 10 tests covering dollarsToCents, centsToDollars, formatCurrency |

### Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
| ----------- | ---------- | ----------- | ------ | -------- |
| PEOPLE-01 | 01-01, 01-02, 01-03 | User can add people to the bill by name | SATISFIED | PersonForm + PeopleList + store.addPerson |
| PEOPLE-02 | 01-01, 01-02, 01-04 | User can add items with name and price | SATISFIED | ItemForm + ItemsList + store.addItem + formatCurrency |
| PEOPLE-03 | 01-01, 01-02, 01-04 | User can assign items to specific people | SATISFIED | ItemAssign checkbox UI + setAssignment |
| PEOPLE-04 | 01-01, 01-02, 01-04 | User can mark items as "shared" to split across selected people | SATISFIED | ItemAssign multi-select + setAssignment(array) |
### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
| ---- | ---- | ------- | -------- | ------ |
| None | - | - | - | No blocking issues found |
**Anti-pattern scan results:**
- No TODO/FIXME/XXX/HACK/PLACEHOLDER comments found
- No "Not implemented" or "coming soon" text found
- No console.log statements found
- No empty return patterns (return null, return {}, return []) in component files
- No empty arrow function handlers (=> {})
### Human Verification Required
The following items require human testing in the browser:
1. **Full bill entry flow**
- **Test:** Start dev server with `npm run dev`, open in browser
- **Expected:** App displays "Bill Splitter" heading with People and Items sections
- **Why human:** Visual appearance and UI interaction cannot be verified programmatically
2. **People add/display reactivity**
- **Test:** Type "Alice" in person input, click Add Person
- **Expected:** Alice appears immediately in people list without page refresh
- **Why human:** Real-time UI reactivity requires visual confirmation
3. **Item add with price formatting**
- **Test:** Type "Pizza" and "15.99", click Add Item
- **Expected:** Item shows with "$15.99" formatted price
- **Why human:** Currency formatting display requires visual verification
4. **Single-person assignment**
- **Test:** Check one checkbox for an item
- **Expected:** Checkbox stays checked, assignment saved
- **Why human:** Checkbox state and persistence requires interaction
5. **Multi-person shared assignment**
- **Test:** Check multiple checkboxes for an item
- **Expected:** Multiple checkboxes stay checked (shared item)
- **Why human:** Multi-select behavior requires interaction testing
6. **Error feedback**
- **Test:** Submit empty person name or invalid price "abc"
- **Expected:** Error message appears, inputs not cleared
- **Why human:** Error message display and UX requires visual verification
### Automated Test Status
**Note:** Automated tests could not be executed during verification due to sandbox environment restrictions (ENOENT error for /tmp/claude directory). However:
- Test files exist and are properly structured
- Tests cover all 4 PEOPLE requirements (PEOPLE-01 through PEOPLE-04)
- Tests cover all currency utility functions
- SUMMARY files confirm tests were passing during execution (20/20)
- Implementation matches test interfaces exactly
### Summary
**All Phase 1 requirements (PEOPLE-01, PEOPLE-02, PEOPLE-03, PEOPLE-04) are verified:**
1. **Artifacts exist:** All 8 source files + 2 test files + config files present
2. **Artifacts are substantive:** No stub implementations, all have real functionality
3. **Key links are wired:** All imports and function calls verified via grep
4. **No blocking anti-patterns:** No TODOs, placeholders, or empty implementations
5. **Requirements mapped:** All 4 requirement IDs traced to implementation
The phase goal "Enable users to add people, add items with prices, and assign items to people (single or shared)" is achieved.
