+# Phase 14 Plan 03: Service Layer Async Conversion Summary
+
+**All 9 service files (30 functions) converted from synchronous SQLite to async PostgreSQL operations with PGlite smoke test validation**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-04-04T10:31:16Z
+- **Completed:** 2026-04-04T10:35:35Z
+- **Tasks:** 2
+- **Files modified:** 9
+
+## Accomplishments
+- Converted 30 exported service functions across 9 files to async/await
+- Removed all SQLite-only method calls (.all(), .get(), .run()) from service layer
+- Converted 5 transaction callbacks to async pattern (category delete, thread resolve/reorder, setup sync)
+- Fixed OAuth boolean type mismatch (used: 0/1 -> false/true)
+- Server startup now awaits async seedDefaults()
+- PGlite smoke test validates createItem service works end-to-end against async DB
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Convert core data services to async** - `4d705af` (feat)
+2. **Task 2: Convert auth/oauth/csv services, update server index** - `75bf3e0` (feat)
+
+## Files Created/Modified
+- `src/server/services/item.service.ts` - 6 async functions for item CRUD
+- `src/server/services/category.service.ts` - 4 async functions, async transaction in deleteCategory
+- `src/server/services/thread.service.ts` - 10 async functions, async transactions in resolveThread/reorderCandidates
+- `src/server/services/setup.service.ts` - 8 async functions, async transaction in syncSetupItems
+- `src/server/services/totals.service.ts` - 2 async functions for aggregate queries
+- `src/server/services/auth.service.ts` - 10 async functions for user/session/API key management
+- `src/server/services/oauth.service.ts` - 7 async functions, boolean conversion for used field
+- `src/server/services/csv.service.ts` - 2 async functions for CSV export/import
+- `src/server/index.ts` - seedDefaults() call now awaited
+
+## Decisions Made
+- Removed .all() calls entirely since async Drizzle returns arrays directly from queries
+- Used destructured array pattern `const [row] = await ...` for all single-row queries (replaces .get())
+- Converted OAuth `used` field from integer (0/1) to native boolean (false/true) to match PostgreSQL schema
+- image.service.ts was already fully async (no DB calls), no changes needed
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Installed missing @electric-sql/pglite dependency**
+- **Found during:** Task 2 (PGlite smoke test)
+- **Issue:** pglite package not installed, required by test helper db.ts for in-memory PostgreSQL
+- **Fix:** Ran `bun add @electric-sql/pglite`
+- **Files modified:** package.json (auto-updated by bun)
+- **Verification:** Smoke test passes, createItem returns valid item
+- **Committed in:** Part of bun lockfile (auto-managed)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 blocking)
+**Impact on plan:** Dependency installation required for smoke test. No scope creep.
+
+## Issues Encountered
+None - mechanical conversion applied consistently across all files.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Known Stubs
+None - all service functions are fully wired with real async database operations.
+
+## Next Phase Readiness
+- All service functions are async, ready for route layer conversion (Plan 04)
+- Callers (route handlers) still call these functions synchronously -- they need to await the returned promises
+- Test infrastructure (PGlite) confirmed working for service-level validation
