Phase 25 Plan 01: Catalog Enrichment Data Layer Summary

globalItems attribution columns (sourceUrl, imageCredit, imageSourceUrl) with unique(brand, model) constraint, upsertGlobalItem/bulkUpsertGlobalItems service functions, and Zod schemas — 21 tests passing

Performance

• Duration: ~3 min
• Started: 2026-04-10T08:55:26Z
• Completed: 2026-04-10T08:58:39Z
• Tasks: 2
• Files modified: 5

Accomplishments

• Added three attribution columns to globalItems table with unique(brand, model) constraint and generated migration
• Implemented upsertGlobalItem with onConflictDoUpdate, three-way tag sync, and created/updated tracking
• Implemented bulkUpsertGlobalItems processing arrays in a single atomic transaction
• Defined upsertGlobalItemSchema and bulkUpsertGlobalItemsSchema Zod validation schemas
• All 21 tests pass (13 pre-existing + 8 new upsert operation tests)

Task Commits

Each task was committed atomically:

1. Task 1: Schema migration — attribution columns + unique constraint - 39ef9cc (feat)
2. Task 2: TDD RED — failing tests - 9093a2c (test)
3. Task 2: TDD GREEN — Zod schemas, service functions, tests passing - c8ebbf8 (feat)

Note: TDD tasks have multiple commits (test RED → feat GREEN)

Files Created/Modified

• src/db/schema.ts - Added sourceUrl, imageCredit, imageSourceUrl columns and unique().on(brand, model) constraint to globalItems
• drizzle-pg/0003_loving_serpent_society.sql - Migration adding 3 columns + unique constraint
• src/shared/schemas.ts - Added upsertGlobalItemSchema and bulkUpsertGlobalItemsSchema
• src/shared/types.ts - Added UpsertGlobalItemInput and BulkUpsertGlobalItemsInput types
• src/server/services/global-item.service.ts - Added upsertGlobalItem, bulkUpsertGlobalItems, syncGlobalItemTags
• tests/services/global-item.service.test.ts - Added 8 upsert operation tests

Decisions Made

• Three-way tag handling: undefined leaves existing tags untouched, [] clears all tags, [names] replaces tags. This allows callers to selectively update tags without clobbering existing data.
• Unique constraint on (brand, model): Required for ON CONFLICT DO UPDATE semantics. Without it, duplicate inserts would fail rather than update.
• Created/updated tracking via pre-check: The service checks for existing row before upsert to accurately report created vs updated counts, since ON CONFLICT DO UPDATE doesn't distinguish via returning rows alone.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed drizzle-kit generated spurious duplicate DDL in migration 0003

• Found during: Task 1 (schema migration)
• Issue: drizzle-kit generated a migration that re-created global_item_tags, re-added FKs on items and thread_candidates, and re-added oauth_codes.user_id — all already present in migration 0002. PGlite tests failed with "relation already exists".
• Fix: Trimmed migration 0003 to only include the three new ALTER TABLE ADD COLUMN statements and the unique constraint.
• Files modified: drizzle-pg/0003_loving_serpent_society.sql
• Verification: 21 tests pass including all new upsert tests
• Committed in: c8ebbf8 (Task 2 feat commit)

---

Total deviations: 1 auto-fixed (Rule 1 - bug in generated migration) Impact on plan: Fix was necessary for test correctness. No scope creep.

Issues Encountered

• drizzle-kit migration generation included duplicate DDL from prior migrations — likely a state tracking issue in the drizzle-kit snapshots. Fixed by manually editing the migration to contain only the new changes.

User Setup Required

None - no external service configuration required. Production database push (bun run db:push) will apply the migration when the database is available.

Next Phase Readiness

• Data layer complete: globalItems has attribution columns, unique constraint, and upsert service functions
• Plan 02 (HTTP routes + MCP tools) can now import upsertGlobalItem and bulkUpsertGlobalItems directly
• No blockers
