+# Phase 7 Plan 02: Weight Unit UI Wiring Summary
+
+**Segmented g/oz/lb/kg toggle in TotalsBar with all 8 weight display call sites wired to user-selected unit**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-16T11:20:20Z
+- **Completed:** 2026-03-16T11:23:32Z
+- **Tasks:** 2 (1 auto + 1 checkpoint auto-approved)
+- **Files modified:** 8
+
+## Accomplishments
+- Added segmented pill toggle (g/oz/lb/kg) to TotalsBar with persistent settings via useUpdateSetting
+- Wired all 8 formatWeight call sites to pass the selected unit from useWeightUnit hook
+- All 108 existing tests pass with no regressions, lint clean
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add unit toggle to TotalsBar and update all call sites** - `faa4378` (feat)
+2. **Task 2: Verify weight unit selection end-to-end** - auto-approved (checkpoint)
+
+## Files Created/Modified
+- `src/client/components/TotalsBar.tsx` - Added unit toggle UI, useUpdateSetting mutation, and unit-aware formatWeight calls
+- `src/client/components/ItemCard.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/components/CandidateCard.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/components/CategoryHeader.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/components/SetupCard.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/components/ItemPicker.tsx` - Added useWeightUnit import and unit parameter to formatWeight
+- `src/client/routes/index.tsx` - Added useWeightUnit import and unit parameter to Dashboard formatWeight
+- `src/client/routes/setups/$setupId.tsx` - Added useWeightUnit import and unit parameter to Setup Detail formatWeight
+
+## Decisions Made
+- Unit toggle placed between title and stats in TotalsBar's flex container, keeping it visible but non-dominant as a small utility control
+- Biome requires `type` imports after value imports in destructured statements (e.g., `{ formatWeight, type WeightUnit }`)
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed import order for WeightUnit type in TotalsBar.tsx**
+- **Found during:** Task 1 (TotalsBar modification)
+- **Issue:** Biome lint required `type WeightUnit` to come after value imports in destructured import
+- **Fix:** Changed `{ type WeightUnit, formatPrice, formatWeight }` to `{ formatPrice, formatWeight, type WeightUnit }`
+- **Files modified:** src/client/components/TotalsBar.tsx
+- **Verification:** `bun run lint` passes clean
+- **Committed in:** faa4378 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug - lint import ordering)
+**Impact on plan:** Trivial import ordering fix. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Phase 7 (Weight Unit Selection) is fully complete
+- All 3 requirements (UNIT-01, UNIT-02, UNIT-03) satisfied
+- Ready to proceed to Phase 8 (Candidate Status & Category Icons)
