+# Phase 11 Plan 02: Drag-to-Reorder UI Summary
+
+Drag-to-reorder candidate ranking with list/grid view toggle, gold/silver/bronze rank badges, and framer-motion Reorder.Group with tempItems flicker prevention.
+
+## What Was Built
+
+### Task 1: useReorderCandidates hook + uiStore view mode + CandidateListItem component
+- Added `useReorderCandidates` mutation hook to `useCandidates.ts` using `apiPatch` to hit `PATCH /api/threads/:id/candidates/reorder`
+- Added `candidateViewMode: "list" | "grid"` and `setCandidateViewMode` to `uiStore.ts`
+- Created `CandidateListItem.tsx` — horizontal card for list view with drag handle (GripVertical), RankBadge (medal icon), 48x48 image thumbnail, badge row (weight/price/category/status/pros-cons), and hover-reveal action buttons
+- Exported `RankBadge` component (gold `#D4AF37`, silver `#C0C0C0`, bronze `#CD7F32`) for reuse
+- Added `style` prop support to `LucideIcon` for colored medal icons
+- Added `pros` and `cons` fields to `CandidateWithCategory` in `useThreads.ts` (Rule 2 auto-fix — missing after Phase 10)
+
+### Task 2: Thread detail page with view toggle, Reorder.Group, rank badges in grid view
+- Updated `CandidateCard.tsx`: added `rank?: number` prop and renders `<RankBadge rank={rank} />` in badge row
+- Updated `threads/$threadId.tsx`:
+  - List/grid view toggle (LayoutList / LayoutGrid icons) using `candidateViewMode` from uiStore
+  - Active list view: `<Reorder.Group>` wrapping `<CandidateListItem>` instances for drag-to-reorder
+  - Resolved list view: plain `<div>` with `<CandidateListItem isActive={false}>` — rank badges visible, drag handles hidden
+  - Grid view: existing `<CandidateCard>` grid with `rank={index + 1}` passed to each card
+  - `tempItems` state: holds in-progress drag order, falls back to `thread.candidates` when null
+  - `handleDragEnd`: fires `reorderMutation.mutate({ orderedIds })` and clears tempItems on settled
+  - `useEffect` clears tempItems when `thread?.candidates` reference changes (fresh server data)
+
+### Task 3: Human verification (auto-approved — auto_chain_active)
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing] Added pros/cons fields to CandidateWithCategory in useThreads.ts**
+- **Found during:** Task 1 (needed by CandidateListItem)
+- **Issue:** `CandidateWithCategory` interface in `useThreads.ts` was missing `pros` and `cons` fields added in Phase 10. CandidateListItem needed these to render the "+/- Notes" badge.
+- **Fix:** Added `pros: string | null` and `cons: string | null` to the interface
+- **Files modified:** `src/client/hooks/useThreads.ts`
+- **Commit:** acfa995
+
+**2. [Rule 2 - Missing] Added style prop to LucideIcon component**
+- **Found during:** Task 1 (needed by RankBadge for medal colors)
+- **Issue:** LucideIcon only accepted `className` for styling; RankBadge needed inline `style={{ color }}` for gold/silver/bronze hex colors not achievable via Tailwind
+- **Fix:** Added optional `style?: React.CSSProperties` prop to LucideIcon and passed through to icon component
+- **Files modified:** `src/client/lib/iconData.tsx`
+- **Commit:** acfa995
+
+## Self-Check: PASSED
+
+All created/modified files exist. Both task commits (acfa995, 94c07e7) confirmed in git log.
