## Goal Achievement

### Observable Truths

| #  | Truth                                                                                                               | Status     | Evidence                                                                                       |
|----|---------------------------------------------------------------------------------------------------------------------|------------|-----------------------------------------------------------------------------------------------|
| 1  | User can click a classification badge on any item card within a setup and it cycles through base weight, worn, consumable | VERIFIED | ClassificationBadge renders in $setupId.tsx per item; nextClassification cycles the three values; useUpdateItemClassification mutation fires PATCH call |
| 2  | Items default to base weight classification when added to a setup                                                   | VERIFIED   | schema.ts: `classification text NOT NULL DEFAULT 'base'`; syncSetupItems uses `classificationMap.get(itemId) ?? "base"` |
| 3  | Same item in different setups can have different classifications                                                     | VERIFIED   | Classification stored on setupItems join table (not items); test confirmed in setup.service.test.ts |
| 4  | Classifications persist after adding/removing other items from the setup (syncSetupItems preserves them)            | VERIFIED   | syncSetupItems reads Map<itemId, classification> before delete, restores after re-insert; 2 tests confirm |
| 5  | Setup detail view shows separate weight subtotals for base weight, worn weight, consumable weight, and total        | VERIFIED   | WeightSummaryCard computes baseWeight/wornWeight/consumableWeight/totalWeight and renders 4 SubtotalColumn components |
| 6  | User can view a donut chart showing weight distribution by category in the setup                                    | VERIFIED   | WeightSummaryCard uses Recharts PieChart+Pie with innerRadius=55/outerRadius=80; default viewMode="category" |
| 7  | User can toggle the chart between category breakdown and classification breakdown via pill toggle                   | VERIFIED   | Pill toggle button array maps over VIEW_MODES ["category","classification"]; state switches chartData source |
| 8  | Hovering a chart segment shows category/classification name, weight in selected unit, and percentage                | VERIFIED   | CustomTooltip renders name, formatWeight(weight, unit), (percent*100).toFixed(1)% |
| 9  | Total weight displayed in the center of the donut hole                                                              | VERIFIED   | `<Label value={formatWeight(totalWeight, unit)} position="center" .../>` inside Pie |

**Score:** 9/9 truths verified

### Key Link Verification

#### Plan 01 Key Links

| From | To | Via | Status | Details |
|---|---|---|---|---|
| `ClassificationBadge.tsx` | `/api/setups/:id/items/:itemId/classification` | useUpdateItemClassification mutation hook (apiPatch) | VERIFIED | useSetups.ts exports useUpdateItemClassification which calls `apiPatch(.../classification, ...)`; $setupId.tsx imports and calls it |
| `src/server/routes/setups.ts` | `src/server/services/setup.service.ts` | updateItemClassification service call | VERIFIED | Routes imports updateItemClassification from service; calls it in PATCH handler |
| `src/server/services/setup.service.ts` | `src/db/schema.ts` | setupItems.classification column | VERIFIED | service.ts uses `setupItems.classification` in select (line 56) and `set({ classification })` in update (line 143) |
| `src/client/routes/setups/$setupId.tsx` | `src/client/components/ClassificationBadge.tsx` | ClassificationBadge rendered on each ItemCard | VERIFIED | Imported at line 4; rendered inside item map at lines 235-245 |

#### Plan 02 Key Links

| From | To | Via | Status | Details |
|---|---|---|---|---|
| `WeightSummaryCard.tsx` | recharts | PieChart, Pie, Cell, Tooltip, Label, ResponsiveContainer imports | VERIFIED | All six named imports from "recharts" at lines 2-9 |
| `WeightSummaryCard.tsx` | `src/client/lib/formatters.ts` | formatWeight for subtotals and tooltip display | VERIFIED | `formatWeight` imported at line 12; used in SubtotalColumn, CustomTooltip, and center Label |
| `src/client/routes/setups/$setupId.tsx` | `WeightSummaryCard.tsx` | WeightSummaryCard rendered with setup.items prop | VERIFIED | Imported at line 7; rendered as `<WeightSummaryCard items={setup.items} />` at line 196 |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|---|---|---|---|---|
| CLAS-01 | 09-01 | User can classify each item within a setup as base weight, worn, or consumable | SATISFIED | ClassificationBadge + PATCH endpoint + updateItemClassification service all wired and tested |
| CLAS-02 | 09-02 | Setup totals display base weight, worn weight, consumable weight, and total separately | SATISFIED | WeightSummaryCard renders 4 SubtotalColumn components with computed weights |
| CLAS-03 | 09-01 | Items default to "base weight" classification when added to a setup | SATISFIED | DB default "base" + syncSetupItems fallback + test confirms default |
| CLAS-04 | 09-01 | Same item can have different classifications in different setups | SATISFIED | Classification on join table; cross-setup test passes |
| VIZZ-01 | 09-02 | User can view a donut chart showing weight distribution by category in a setup | SATISFIED | Recharts PieChart with buildCategoryChartData, default viewMode="category" |
| VIZZ-02 | 09-02 | User can toggle chart between category view and classification view | SATISFIED | Pill toggle with VIEW_MODES array, setViewMode state updates chartData source |
| VIZZ-03 | 09-02 | User can hover chart segments to see category name, weight, and percentage | SATISFIED | CustomTooltip renders all three fields; passed to PieChart as `content` prop |

No orphaned requirements — all 7 IDs declared in plan frontmatter and accounted for.

### Anti-Patterns Found

No blockers or warnings found in modified files. The only `return null` instance is a standard React guard clause in CustomTooltip (not a stub).

---

### Human Verification Required

The following items cannot be verified programmatically and require a running browser session:

#### 1. Click-to-cycle badge interaction and stopPropagation

**Test:** Open a setup with items. Click a classification badge on one item card.
**Expected:** Badge label cycles Base Weight -> Worn -> Consumable -> Base Weight. The item edit panel does NOT open when clicking the badge.
**Why human:** stopPropagation correctness and visual badge state update require browser execution.

#### 2. Donut chart renders with correct segment proportions

**Test:** Add items with different categories and weights to a setup. View the setup detail page.
**Expected:** Donut chart segments are proportional to weight distribution. Total weight appears in the center hole.
**Why human:** Chart rendering requires browser + Recharts layout.

#### 3. Pill toggle switches chart data

**Test:** Click the "Classification" pill on the WeightSummaryCard.
**Expected:** Chart segments change from category-based colors to indigo/amber/emerald for base/worn/consumable. Tooltips show "Base Weight", "Worn", or "Consumable" labels.
**Why human:** Visual and interactive behavior requires browser.

#### 4. Tooltip on hover

**Test:** Hover over a chart segment.
**Expected:** Tooltip appears with segment name, formatted weight in the selected unit, and percentage.
**Why human:** Hover state requires browser interaction.

#### 5. Weight unit propagation

**Test:** Toggle the weight unit in the top bar (g / oz / lb / kg). Observe WeightSummaryCard.
**Expected:** All four subtotal columns and the donut center label update to the selected unit.
**Why human:** useWeightUnit hook behavior and re-render requires browser.

---

### Test Suite Results

All 121 tests pass across 10 files (32 setup-specific tests across services and routes).

- `tests/services/setup.service.test.ts` — 5 new classification tests pass (default "base", preservation, new item default, cross-setup independence, update from base to worn)
- `tests/routes/setups.test.ts` — 2 new PATCH classification tests pass (valid update + 400 for invalid value)

---

### Summary

Phase 9 goal is fully achieved. All 9 observable truths are verified against the actual codebase — no stubs, no orphaned artifacts, no broken links. The complete vertical slice from DB schema to UI component is wired and exercised by 7 automated tests. Human verification is needed only for visual/interactive browser behaviors (chart rendering, hover tooltips, click cycling), which are structurally sound in the code.
