  - "Image cleanup: call deleteImage() in try/catch on entity deletion (missing object = silent)"

# Phase 17 Plan 02: Server-Side Storage Integration Summary

**Replaced all local filesystem image operations with S3 storage service calls across routes, services, and MCP tools**

## Performance

- **Duration:** 4 min
- **Started:** 2026-04-05T10:19:05Z
- **Completed:** 2026-04-05T10:22:45Z
- **Tasks:** 2
- **Files modified:** 11

## Accomplishments
- All image uploads (direct file and URL fetch) now go through S3 storage service
- All image deletions (item delete, candidate delete, thread delete) use deleteImage() instead of unlink()
- API responses for items, threads, setups, and MCP tools enriched with presigned imageUrl fields
- Static /uploads/* serving removed from server entry point

## Task Commits

Each task was committed atomically:

1. **Task 1: Refactor image service and routes to use storage service** - `5ce3f92` (feat)
2. **Task 2: Wire storage into all routes and MCP tools, remove static serving** - `f5d7907` (feat)

## Files Created/Modified
- `src/server/services/image.service.ts` - Replaced Bun.write/mkdir with uploadImage() call
- `src/server/routes/images.ts` - Replaced local write with uploadImage() for direct uploads
- `src/server/routes/items.ts` - deleteImage() on delete, withImageUrl(s) on GET responses
- `src/server/routes/threads.ts` - deleteImage() on delete, withImageUrls on GET thread candidates
- `src/server/routes/setups.ts` - withImageUrls on GET setup items
- `src/server/index.ts` - Removed /uploads/* static file serving line
- `src/server/mcp/tools/items.ts` - withImageUrl/withImageUrls on list and get tool responses
- `src/server/mcp/tools/threads.ts` - withImageUrls on get_thread candidate responses
- `src/server/mcp/tools/images.ts` - Updated description text (local -> storage)
- `tests/services/image.service.test.ts` - Mock storage service, verify uploadImage calls
- `tests/routes/images.test.ts` - Mock storage service, added upload test

## Decisions Made
- Enrichment happens at route/handler level, not service level, keeping services storage-agnostic
- Setup list endpoint not enriched (doesn't return item images), only setup detail GET /:id

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Removed unused withImageUrl import from threads.ts**
- **Found during:** Task 2 (lint check)
- **Issue:** Imported withImageUrl but only used withImageUrls in threads route
- **Fix:** Removed unused import to pass lint
- **Files modified:** src/server/routes/threads.ts
- **Committed in:** f5d7907 (part of Task 2 commit)

---

**Total deviations:** 1 auto-fixed (1 bug/unused import)
**Impact on plan:** Trivial cleanup. No scope creep.

## Issues Encountered
None

## Known Stubs
None - all image operations fully wired to storage service.

## User Setup Required
None - no additional external service configuration required (MinIO setup was done in Plan 01).

## Next Phase Readiness
- Server-side storage integration complete
- Ready for Plan 03: client-side refactoring to use presigned imageUrl from API responses instead of /uploads/ paths
