Add Gherkin feature spec (specs/features/database-schema-drizzle.feature) covering all 20 acceptance criteria for the database schema. Add comprehensive test suite (tests/database-schema.test.ts) with 103 tests: - AC #7: Drizzle ORM and drizzle-kit installation verification - AC #8-11: Database script existence checks - AC #12: SQLite .db gitignore verification - AC #1-5: Schema column and constraint verification via imports - AC #6: Live in-memory SQLite cascade delete tests - AC #13-17: Seed data verification against local.db - AC #18-20: Database client export verification All tests expected to fail until implementation is complete.
- Add drizzle-orm as dependency to apps/api and root package.json - Add drizzle-kit as dev dependency to apps/api - Add drizzle.config.ts targeting SQLite with schema at ./src/db/schema - Add db:generate, db:migrate, db:studio, db:seed scripts - Update .gitignore: add *.db-shm, *.db-wal, test-results/ - Remove apps/api/src/db/.gitkeep (replaced by actual db module)
Add schema files under apps/api/src/db/schema/: - artists.ts: id (uuid), name, email, preferences (json), rider_template, created_at, updated_at - tours.ts: FK → artists (cascade delete), status enum (planning/confirmed/in_progress/completed), budget (real), dates - gigs.ts: FK → tours (cascade delete), state, rider_status enum (draft/sent/signed), fee (real), venue/promoter info - bookings.ts: FK → gigs (cascade delete), type enum (flight/hotel), cost, check_in/check_out, details (json) - riders.ts: FK → gigs (cascade delete, unique constraint on gig_id), content (json), status enum (draft/sent/signed) - index.ts: barrel export of all tables, enums, and types All foreign keys configured with ON DELETE CASCADE. Rider gig_id has unique index for one-to-one relationship.
Add apps/api/src/db/index.ts: - Create Drizzle client using bun:sqlite native driver - Read DATABASE_URL env var with ./local.db fallback - Enable WAL mode for better concurrent read performance - Enable foreign key enforcement (off by default in SQLite) - Export db client, schema, and DbClient type for route handlers
Add apps/api/src/db/migrate.ts: - Programmatic migration runner using drizzle-orm/bun-sqlite/migrator - Enables WAL mode and foreign keys before running migrations - Reads DATABASE_URL with ./local.db fallback Add apps/api/drizzle/0000_bouncy_fat_cobra.sql: - Initial migration with CREATE TABLE for all 5 tables - Foreign keys with ON DELETE CASCADE properly defined - Unique index on riders.gig_id - Generated by drizzle-kit generate from schema definitions
Add apps/api/src/db/seed.ts with: - 1 artist: 'Chic' with preferences and rider template - 1 tour: 'Spring Groove Tour 2026' (Apr 10-28, planning status, $15k budget) - 5 gigs: NYC → Chicago → Austin → LA → Miami (18-day span) - 2 bookings on first gig: 1 Delta flight ($320) + 1 hotel ($275) - 1 rider in draft status with hospitality/technical/travel/misc sections Seed runs migrations first, clears existing data in FK order, then inserts all sample data. Exports seed() function and auto-runs when executed directly.

Summary
Implements the complete data model using Drizzle ORM inside
apps/api, with SQLite for local development, migration tooling, and a seed script with realistic sample data.Schema (
