+# Phase 12: Comparison View - Context
+
+**Gathered:** 2026-03-17
+**Status:** Ready for planning
+
+
+## Phase Boundary
+
+Users can view all candidates for a thread side-by-side in a tabular comparison layout with relative weight and price deltas. The table scrolls horizontally on narrow viewports with a sticky label column. Resolved threads display the comparison in read-only mode with the winning candidate visually marked. Impact preview (setup deltas) is a separate phase (13).
+
+
+
+
+## Implementation Decisions
+
+### Compare mode entry point
+- Add a third icon to the existing list/grid toggle bar, making it list | grid | compare (three-way toggle)
+- Use `candidateViewMode: 'list' | 'grid' | 'compare'` in uiStore — extends the existing Zustand state
+- Compare icon only appears when 2+ candidates exist in the thread (hidden otherwise)
+- "Add Candidate" button visibility in compare mode is Claude's discretion
+
+### Table orientation and layout
+- Candidates as columns, attribute labels as rows (classic product-comparison pattern — Amazon/Wirecutter style)
+- Sticky left column for attribute labels; table scrolls horizontally on narrow viewports
+- Attribute row order: Image → Name → Rank → Weight (with delta) → Price (with delta) → Status → Product Link → Notes → Pros → Cons
+- Image row: sizing is Claude's discretion (balance compactness with product visibility)
+- Multi-line text (notes, pros, cons): rendering approach is Claude's discretion (keep table scannable)
+
+### Delta highlighting style
+- Lightest candidate's weight cell gets a subtle colored background tint (e.g., bg-green-50); cheapest similarly
+- Non-best cells show delta text in neutral gray — no colored badges for deltas, only the "best" cell gets color
+- Missing weight/price data: Claude's discretion on indicator style (must satisfy COMP-04 — no misleading zeroes)
+- Delta format (absolute + delta, or delta only): Claude's discretion based on readability
+
+### Resolved thread presentation
+- Winner column highlight and trophy/banner approach: Claude's discretion (existing resolution banner + column tint are both available patterns)
+- Interactive elements in resolved comparison (links clickable vs everything static): Claude's discretion, following the existing Phase 11 pattern where resolved threads disable mutation actions but keep read-only indicators
+- Existing resolution banner above the comparison table: Claude's discretion on whether to keep it, remove it, or adapt it
+
+### Claude's Discretion
+- "Add Candidate" button visibility when in compare view
+- Image thumbnail sizing in comparison cells (square crop vs wider aspect)
+- Multi-line text rendering strategy (clamped with expand vs full text)
+- Missing data indicator style (dash with label, empty cell, etc.)
+- Delta format: absolute value + delta underneath, or delta only for non-best cells
+- Winner column marking approach (column tint, trophy icon, or both)
+- Resolved thread interactivity (links clickable vs all read-only)
+- Resolution banner behavior in compare view
+- View mode persistence (already in Zustand — whether compare resets on navigation or persists)
+- Compare toggle icon choice (e.g., Lucide `columns-3`, `table-2`, or similar)
+- Table cell padding, border styling, and overall table chrome
+- Column minimum/maximum widths
+- Keyboard accessibility for horizontal scrolling
+
+
+
+
+## Existing Code Insights
+
+### Reusable Assets
+- `candidateViewMode` in `uiStore` (`stores/uiStore.ts`): Already stores `'list' | 'grid'` — extend to include `'compare'`
+- `CandidateCard` / `CandidateListItem`: Data shape reference for what fields are available per candidate
+- `formatWeight()` / `formatPrice()` in `lib/formatters.ts`: Unit-aware formatting for table cells and deltas
+- `useWeightUnit()` / `useCurrency()` hooks: Current unit/currency for display
+- `RankBadge` (`CandidateListItem.tsx`): Exported component for gold/silver/bronze medals — reuse in compare table name row
+- `StatusBadge` (`StatusBadge.tsx`): Click-to-cycle status — render as static text in compare view (no interaction needed)
+- `LucideIcon` helper: For compare toggle icon and any icons in the table
+- `useThread(threadId)` hook: Returns `thread.candidates[]` with all fields needed (name, weightGrams, priceCents, status, pros, cons, notes, productUrl, imageFilename, categoryName, categoryIcon)
+
+### Established Patterns
+- Three-way toggle: Extend existing `bg-gray-100 rounded-lg p-0.5` toggle bar pattern from thread toolbar
+- Pill badges: blue=weight, green=price, gray=category, purple=pros/cons — table can reference these colors for consistency
+- framer-motion already installed — AnimatePresence for view transitions if desired
+- React Query for server data, Zustand for UI-only state
+- Resolution banner: amber-50 bg with amber-200 border in resolved thread header — reusable pattern for winner column
+
+### Integration Points
+- `src/client/routes/threads/$threadId.tsx`: Add compare view branch to the existing list/grid conditional rendering
+- `src/client/stores/uiStore.ts`: Extend `candidateViewMode` union type to include `'compare'`
+- New component: `ComparisonTable.tsx` (or similar) — receives candidates array, renders the tabular comparison
+- No backend changes needed — all data already available from `useThread` hook
+- No schema changes — this is a pure frontend/UI phase
+
+
+
+
+## Specific Ideas
+
+- Classic product-comparison table like Amazon or Wirecutter — candidates as columns, attributes as rows
+- Subtle green tint on the "best" cell rather than heavy badges or bold formatting — keeps the minimalist feel
+- Gray delta text for non-best values — visual hierarchy: best stands out, others recede
+
+
+
+
+## Deferred Ideas
+
+None — discussion stayed within phase scope

+# Plan 29-01 Summary: Schema + Dominant Color Extraction
+
+## What was built
+- Installed Sharp image processing library for server-side color extraction
+- Added `dominant_color`, `crop_zoom`, `crop_x`, `crop_y` columns to items, global_items, and thread_candidates tables
+- Created `extractDominantColor()` function that resizes image to 1x1 pixel for weighted average color
+- Integrated color extraction into both image upload endpoints (direct and from-url)
+- Updated Zod schemas for items, candidates, and global items to accept new fields
+- Generated Drizzle migration (db:push deferred — requires running database)
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| 1 | cee1500 | Install Sharp for image processing |
+| 2 | 36363a8 | Add dominantColor and crop fields to schema |
+| 3 | b637b10 | Generate migration for image presentation fields |
+| 4 | e305fa7 | Add dominant color extraction via Sharp |
+| 5 | 2696b78 | Extract dominant color in image upload endpoints |
+| 6 | 3480473 | Add image presentation fields to Zod schemas |
+| 7 | — | No changes needed (storage service already spreads fields) |
+
+## Deviations
+- Task 3 (db:push): Database not accessible in dev environment — migration generated but push deferred to deployment. This is non-blocking for frontend work.
+
+## Self-Check: PASSED
+- Sharp installed: YES
+- dominant_color in 3 tables: YES (grep confirms 3 occurrences)
+- Zod schemas updated: YES (3 schemas)
+- Upload returns dominantColor: YES
+- Lint passes: YES
