test expected why_human
Navigate to Collection page and verify unit toggle is visible in TotalsBar A segmented g/oz/lb/kg pill toggle appears in the top bar between the title and stats Cannot verify visual rendering or UI element presence without a browser
test expected why_human
Click 'oz' in the toggle, verify all weight badges update to ounces ItemCards, CategoryHeaders, TotalsBar total, SetupCard weights all update to e.g. '15.9 oz' React Query invalidation and re-render behavior requires runtime verification
test expected why_human
Navigate to Dashboard, then to a Setup detail page, verify weights use selected unit All weight displays across pages reflect the chosen unit after selecting 'oz', 'lb', or 'kg' Cross-page state propagation via settings API requires runtime verification
test expected why_human
Select 'kg', then refresh the page After refresh, weights still display in kg (unit persists) Settings persistence across sessions requires runtime verification

Phase 7: Weight Unit Selection Verification Report

Phase Goal: Users see all weights in their preferred unit across the entire app Verified: 2026-03-16T12:00:00Z Status: human_needed Re-verification: No - initial verification

Goal Achievement

Observable Truths

# Truth Status Evidence
1 formatWeight converts grams to g, oz, lb, kg with correct precision VERIFIED src/client/lib/formatters.ts switch statement with toFixed(1) oz, toFixed(2) lb/kg. 21 tests all pass.
2 formatWeight defaults to grams when no unit is specified (backward compatible) VERIFIED Signature unit: WeightUnit = "g". Test: formatWeight(100) returns "100g".
3 formatWeight handles null/undefined input for all units VERIFIED Null guard if (grams == null) return "--" fires before switch. 7 null/undefined tests pass.
4 useWeightUnit hook returns a valid WeightUnit from settings, defaulting to 'g' VERIFIED useWeightUnit.ts validates against VALID_UNITS array and returns "g" fallback.
5 User can see a unit toggle (g/oz/lb/kg) in the TotalsBar ? NEEDS HUMAN Toggle code exists in TotalsBar.tsx (lines 70-90), but visual rendering requires browser.
6 Clicking a unit in the toggle changes all weight displays across the app ? NEEDS HUMAN useUpdateSetting.mutate({ key: "weightUnit", value: u }) wired. React Query invalidation behavior requires runtime.
7 Weight unit selection persists after page refresh ? NEEDS HUMAN Persistence via GET /api/settings/weightUnit in useSetting. Requires runtime verification.
8 Every weight display in the app uses the selected unit VERIFIED All 9 formatWeight call sites in src/client/ pass unit argument. Grep confirms no bare formatWeight(grams) calls remain in components.

Score: 5/5 automated truths verified, 3/3 runtime truths require human verification

Required Artifacts

Plan 01 Artifacts

Artifact Expected Status Details
src/client/lib/formatters.ts WeightUnit type export and parameterized formatWeight VERIFIED Exports WeightUnit, formatWeight, formatPrice. Contains switch for all 4 units. 28 lines, substantive.
src/client/hooks/useWeightUnit.ts Convenience hook wrapping useSetting for weight unit VERIFIED Exports useWeightUnit. Imports WeightUnit from formatters, useSetting from useSettings. 13 lines, substantive.
tests/lib/formatters.test.ts Unit tests for formatWeight with all 4 units and edge cases VERIFIED 98 lines (min_lines=30 satisfied). 21 tests across 7 describe blocks covering g/oz/lb/kg, null/undefined, backward compat, zero, edge cases. All pass.

src/client/components/ItemCard.tsx Unit-aware item weight display VERIFIED Contains useWeightUnit. formatWeight(weightGrams, unit) on line 127.
src/client/components/CandidateCard.tsx Unit-aware candidate weight display VERIFIED Contains useWeightUnit. formatWeight(weightGrams, unit) on line 93.
src/client/components/CategoryHeader.tsx Unit-aware category total weight display VERIFIED Contains useWeightUnit. formatWeight(totalWeight, unit) on line 90.
src/client/components/SetupCard.tsx Unit-aware setup weight display VERIFIED Contains useWeightUnit. formatWeight(totalWeight, unit) on line 35.
src/client/components/ItemPicker.tsx Unit-aware item picker weight display VERIFIED Contains useWeightUnit. formatWeight(item.weightGrams, unit) on line 119.
src/client/routes/index.tsx Unit-aware dashboard weight display VERIFIED Contains useWeightUnit. formatWeight(global?.totalWeight ?? null, unit) on line 34.
src/client/routes/setups/$setupId.tsx Unit-aware setup detail weight display VERIFIED Contains useWeightUnit. formatWeight(totalWeight, unit) on line 110.

Requirements Coverage

Requirement Source Plan(s) Description Status Evidence
UNIT-01 07-02-PLAN User can select preferred weight unit (g, oz, lb, kg) from settings VERIFIED (automated) / NEEDS HUMAN (runtime) Segmented toggle code in TotalsBar.tsx lines 70-90. Runtime: needs human to confirm visual and click behavior.
UNIT-02 07-01-PLAN, 07-02-PLAN All weight displays across the app reflect the selected unit VERIFIED All 9 formatWeight call sites in components pass unit. No bare formatWeight(grams) calls remain.
UNIT-03 07-01-PLAN, 07-02-PLAN Weight unit preference persists across sessions VERIFIED (mechanism) / NEEDS HUMAN (runtime) useSetting("weightUnit") reads from /api/settings/weightUnit. useUpdateSetting writes to same endpoint. Persistence across refresh requires runtime verification.

No orphaned requirements. REQUIREMENTS.md marks all three as complete for Phase 7. All three requirement IDs appear in at least one plan's requirements field.

Anti-Patterns Found

File Line Pattern Severity Impact
— — None found — —

Scanned all 11 modified files. No TODOs, FIXMEs, placeholder comments, empty implementations, or stub returns found. All formatWeight calls outside formatters.ts carry the unit argument.

Human Verification Required

1. Unit Toggle Visibility

Test: Start bun run dev:client and bun run dev:server, navigate to http://localhost:5173/collection Expected: A segmented pill toggle showing g / oz / lb / kg is visible in the sticky top bar, positioned between the GearBox title and the stats (items / total / spent) Why human: Visual rendering cannot be verified programmatically

2. Unit Toggle Click Behavior

Test: With the app running, click "oz" in the toggle on the Collection page Expected: All weight badges on ItemCards, CategoryHeader totals, and the TotalsBar total update immediately to ounce values (e.g., "15.9 oz"). No page reload required. Why human: React Query cache invalidation and live re-render require runtime observation

3. Cross-Page Unit Consistency

Test: Select "lb" on the Collection page, then navigate to the Dashboard (/), then navigate to a Setup detail page Expected: The Dashboard Collection card weight shows in lb; all weights in the Setup detail sticky bar and ItemCards show in lb Why human: Cross-page state propagation via TanStack Router and shared React Query cache requires runtime verification

4. Persistence Across Refresh

Test: Select "kg", then hard-refresh the page (Ctrl+R or F5) Expected: After refresh, all weights still display in kg. The kg button appears active/highlighted in the toggle. Why human: Browser session handling and settings API round-trip require runtime verification

Gaps Summary

No automated gaps found. All artifacts exist, are substantive, and are correctly wired. The 3 human verification items are standard runtime behaviors (visual rendering, live updates, persistence) that cannot be verified statically.

The implementation is complete and correct based on static analysis:

  • formatWeight conversion math is verified by 21 passing tests
  • All 8 component call sites pass unit from useWeightUnit() — confirmed by exhaustive grep
  • TotalsBar contains the full toggle UI with useUpdateSetting wired to weightUnit key
  • useWeightUnit correctly wraps useSetting("weightUnit") with type validation and "g" default
  • Full test suite (108 tests) passes with no regressions
  • Lint clean (78 files, no issues)
  • All 4 phase commits verified in git history (431c179, 6cac0a3, ada3791, faa4378)
