+# Phase 5 Plan 1: Image Display Fix & Hero Area Summary
+
+**Fixed image persistence bug (Zod schema missing imageFilename) and redesigned ImageUpload as 4:3 hero area at top of item/candidate forms**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-15T16:08:51Z
+- **Completed:** 2026-03-15T16:11:27Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Identified and fixed root cause of image display bug: imageFilename was missing from Zod validation schemas, causing @hono/zod-validator to silently strip it from payloads
+- Redesigned ImageUpload into a full-width 4:3 hero image area with placeholder, preview, upload spinner, and remove states
+- Moved ImageUpload to first element in both ItemForm and CandidateForm, removing redundant labels
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Fix image display bug and investigate root cause** - `8c0529c` (fix)
+2. **Task 2: Redesign ImageUpload as hero area and move to top of forms** - `3243be4` (feat)
+
+## Files Created/Modified
+- `src/shared/schemas.ts` - Added imageFilename to createItemSchema and createCandidateSchema
+- `src/client/components/ImageUpload.tsx` - Redesigned as 4:3 hero area with placeholder/preview/spinner states
+- `src/client/components/ItemForm.tsx` - Moved ImageUpload to top, removed label wrapper
+- `src/client/components/CandidateForm.tsx` - Moved ImageUpload to top, removed label wrapper
+
+## Decisions Made
+- Used inline SVGs instead of adding lucide-react dependency -- only 3 icons needed, avoids bundle bloat
+- Root cause identified as Zod schema issue, not static file serving or Vite proxy (both were working correctly)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Image display and upload flow fully functional
+- Hero area component ready for any future image-related enhancements in plan 05-02
+- Forms have clean image-first layout
