+# Phase 35 Plan 03: Cursor-Pointer Audit Summary
+
+Explicit `cursor-pointer` added to all interactive elements that lacked it — ItemCard navigable outer button, FabMenu menu item buttons and main FAB, and BottomTabBar's three anonymous tab buttons. Resolves FIX-05.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Add cursor-pointer to ItemCard navigable case | e1d516c | src/client/components/ItemCard.tsx |
+| 2 | Add cursor-pointer to FabMenu and BottomTabBar buttons | d58f7fa | src/client/components/FabMenu.tsx, src/client/components/BottomTabBar.tsx |
+
+## What Was Built
+
+### Task 1 — ItemCard (FIX-05)
+
+The outer `<button>` in `ItemCard.tsx` had a conditional className: `cursor-default` when `linkTo === null` (setup cards, non-navigable), but was missing `cursor-pointer` in the non-null branch (collection cards, navigable). Added `cursor-pointer` to the non-null branch. The `cursor-default` branch is preserved unchanged.
+
+### Task 2 — FabMenu and BottomTabBar (FIX-05)
+
+FabMenu: Added `cursor-pointer` to both `motion.button` elements — the menu item buttons rendered per `menuItems` array, and the main FAB toggle button.
+
+BottomTabBar: Added `cursor-pointer` to all three anonymous user `<button>` elements — the collection tab, setups tab, and search tab. Biome formatter required multi-line attribute expansion (type, onClick, className each on their own line) to pass lint.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Format] Biome formatter required multi-line button attribute splitting**
+- **Found during:** Task 2 verification (lint)
+- **Issue:** Biome's formatter rejected single-line `<button type="button" onClick={...} className="cursor-pointer">` — three attributes triggered multi-line expansion requirement
+- **Fix:** Split all three BottomTabBar button elements to multi-line format matching Biome's output
+- **Files modified:** src/client/components/BottomTabBar.tsx
+- **Commit:** d58f7fa (included in same task commit)
+
+## Verification
+
+- `grep -n "cursor-pointer hover:border-gray-200" ItemCard.tsx` — 1 match on outer button (confirmed)
+- `grep -n "cursor-default" ItemCard.tsx` — 1 match on null linkTo branch (preserved)
+- `grep -c "cursor-pointer" FabMenu.tsx` — 2 (menu item button + FAB button)
+- `grep -c "cursor-pointer" BottomTabBar.tsx` — 3 (collection, setups, search tabs)
+- `bun run lint` — passes (0 errors, 1 pre-existing warning in scripts/)
+- `bun test` — 464 pass, 0 fail
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None — pure CSS class changes, no logic, data flow, or auth boundary touched.
+
