+# Phase 16 Plan 02: Service Layer userId Scoping Summary
+
+**All 7 service files accept userId parameter with and(eq) isolation on every query — no unscoped reads or writes remain**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-04-05T08:40:21Z
+- **Completed:** 2026-04-05T08:43:55Z
+- **Tasks:** 2
+- **Files modified:** 7
+
+## Accomplishments
+- Every exported service function now accepts userId as second parameter with no default db values
+- All get-by-id, update, and delete operations use and(eq(id), eq(userId)) for cross-user isolation
+- Thread resolution includes userId on new item creation and verifies category ownership
+- Setup item sync validates both setup and item ownership before inserting
+- Candidate operations (add, update, remove) verify parent thread belongs to user
+- CSV import scopes category lookup/creation and item insertion to the importing user
+- Category deletion uses dynamic Uncategorized lookup per user instead of hardcoded ID
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update item, category, totals, and CSV services** - `8d85d28` (feat)
+2. **Task 2: Update thread, setup, and auth services** - `242cace` (feat)
+
+## Files Created/Modified
+- `src/server/services/item.service.ts` - userId on all 6 functions, and() isolation on get/update/delete/duplicate
+- `src/server/services/category.service.ts` - userId on all functions, async Postgres patterns, dynamic Uncategorized lookup on delete
+- `src/server/services/totals.service.ts` - userId filtering on category and global totals
+- `src/server/services/csv.service.ts` - userId on import/export, user-scoped category cache, userId on item inserts
+- `src/server/services/thread.service.ts` - userId on all 9 functions, ownership verification on candidate ops, userId on resolveThread item insert
+- `src/server/services/setup.service.ts` - userId on all 7 functions, inArray item ownership validation in syncSetupItems
+- `src/server/services/auth.service.ts` - removed prodDb defaults, reordered createApiKey params
+
+## Decisions Made
+- Category deletion now uses `getOrCreateUncategorized(db, userId)` instead of hardcoded category ID 1, supporting multi-user where each user has their own Uncategorized category
+- Candidate operations verify parent thread ownership (not just candidate existence) to prevent cross-user manipulation via candidate ID guessing
+- `syncSetupItems` validates item ownership via `inArray` query before inserting, silently filtering out items that don't belong to the user
+- `resolveThread` verifies the candidate's category belongs to the user, falling back to `getOrCreateUncategorized` if not
+- `createApiKey` parameter order changed from `(db, name, userId)` to `(db, userId, name)` for consistency with the userId-second-param pattern
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Category service sync SQLite to async Postgres patterns**
+- **Found during:** Task 1 (category.service.ts)
+- **Issue:** Category service still used synchronous SQLite patterns (.get(), .all(), .run()) that don't work with Postgres driver
+- **Fix:** Converted all functions to async with await and array destructuring, consistent with other services
+- **Files modified:** src/server/services/category.service.ts
+- **Verification:** All functions now use async/await patterns
+- **Committed in:** 8d85d28 (Task 1 commit)
+
+**2. [Rule 2 - Missing Critical] Added getCategoryById function**
+- **Found during:** Task 1 (category.service.ts)
+- **Issue:** Category service had no getCategoryById function — needed for userId-scoped lookups
+- **Fix:** Added getCategoryById(db, userId, id) with and(eq) isolation
+- **Files modified:** src/server/services/category.service.ts
+- **Verification:** Function exists with proper userId scoping
+- **Committed in:** 8d85d28 (Task 1 commit)
+
+**3. [Rule 2 - Missing Critical] Setup operations verify ownership before mutations**
+- **Found during:** Task 2 (setup.service.ts)
+- **Issue:** updateItemClassification and removeSetupItem had no ownership checks — raw SQL conditions without setup ownership validation
+- **Fix:** Added setup ownership verification before both operations
+- **Files modified:** src/server/services/setup.service.ts
+- **Verification:** Both functions check setup belongs to user before proceeding
+- **Committed in:** 242cace (Task 2 commit)
+
+---
+
+**Total deviations:** 3 auto-fixed (1 bug, 2 missing critical)
+**Impact on plan:** All auto-fixes necessary for correctness and security. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Known Stubs
+None - all service functions are fully implemented with proper userId scoping.
+
+## Next Phase Readiness
+- All services now accept userId — route handlers (Plan 03) can pass c.get("userId") from auth middleware
+- MCP tools (Plan 04) can pass userId from MCP auth context
+- Tests will need updating to pass userId to all service calls
+
+## Self-Check: PASSED
+
+All 7 modified service files exist. Both task commits (8d85d28, 242cace) verified in git log.
