# Phase 17 Plan 03: Client Image URL Migration and Migration Script Summary

**Replaced all client /uploads/ path references with presigned S3 URLs and created one-time image migration script**

## Performance

- **Duration:** 4 min
- **Started:** 2026-04-05T10:25:33Z
- **Completed:** 2026-04-05T10:30:00Z
- **Tasks:** 2
- **Files modified:** 11

## Accomplishments
- All 6 client image components now use imageUrl from API responses instead of constructing /uploads/ paths
- Zero /uploads/ references remain in client code
- Migration script reads uploads/ directory and uploads each file to MinIO preserving filenames
- ImageUpload component supports both presigned URLs (existing images) and local object URLs (new uploads)

## Task Commits

Each task was committed atomically:

1. **Task 1: Update client components to use imageUrl from API responses** - `8c64bf9` (feat)
2. **Task 2: Create image migration script** - `6f40f94` (feat)

## Files Created/Modified
- `src/client/components/ImageUpload.tsx` - Added imageUrl prop, local preview via createObjectURL
- `src/client/components/ItemCard.tsx` - Added imageUrl prop, use presigned URL for display
- `src/client/components/CandidateCard.tsx` - Added imageUrl prop, use presigned URL for display
- `src/client/components/CandidateListItem.tsx` - Added imageUrl to interface, use presigned URL
- `src/client/components/ComparisonTable.tsx` - Added imageUrl to interface, use presigned URL
- `src/client/components/CollectionView.tsx` - Pass imageUrl to ItemCard
- `src/client/components/ItemForm.tsx` - Pass imageUrl to ImageUpload from item record
- `src/client/components/CandidateForm.tsx` - Pass imageUrl to ImageUpload from candidate record
- `src/client/routes/setups/$setupId.tsx` - Pass imageUrl to ItemCard
- `src/client/routes/threads/$threadId.tsx` - Pass imageUrl to CandidateCard
- `scripts/migrate-images-to-minio.ts` - One-time migration from uploads/ to S3

## Decisions Made
- Used createObjectURL for immediate preview after upload (presigned URL not available until next GET)
- Migration script does not auto-delete originals (user deletes manually after verification)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required. Migration script usage documented in script header comments.

## Next Phase Readiness
- Full stack now uses MinIO for image storage
- Migration script ready to run for existing deployments: `bun run scripts/migrate-images-to-minio.ts`
- All client and server /uploads/ references eliminated
