Set up PostgreSQL database layer with async SQLAlchemy 2.0 and asyncpg driver. Implements 6 core tables (games, routes, pokemon, route_encounters, nuzlocke_runs, encounters) with foreign keys, indexes, and an initial Alembic migration. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Design and implement the database schema for persistent storage.
|
|
|
|
## Decisions
|
|
- **Database**: PostgreSQL 16 (already in docker-compose)
|
|
- **ORM**: SQLAlchemy 2.0 (async) with asyncpg driver
|
|
- **Migrations**: Alembic
|
|
- **Async**: Full async — asyncpg + async SQLAlchemy sessions
|
|
|
|
## Checklist
|
|
- [x] Choose database (PostgreSQL)
|
|
- [x] Set up database connection and ORM/query builder (SQLAlchemy 2.0 async + asyncpg)
|
|
- [x] Design and create tables/collections:
|
|
- [x] Games (id, name, slug, generation, region, box_art_url, release_year)
|
|
- [x] Routes (id, name, game_id, order)
|
|
- [x] Pokemon (id, national_dex, name, types[], sprite_url)
|
|
- [x] RouteEncounters (id, route_id, pokemon_id, encounter_method, encounter_rate) — unique(route, pokemon, method)
|
|
- [x] NuzlockeRuns (id, game_id, name, status, rules jsonb, started_at, completed_at)
|
|
- [x] Encounters (id, run_id, route_id, pokemon_id, nickname, status, catch_level, faint_level, caught_at)
|
|
- [x] Set up migrations system (Alembic)
|
|
- [ ] Add seed data for initial games/routes/Pokémon
|
|
- [x] Create indexes for common queries (FK indexes on routes, route_encounters, nuzlocke_runs, encounters; status index on nuzlocke_runs)
|
|
|
|
## Notes
|
|
- Use foreign keys for referential integrity
|
|
- Status fields should be enums
|
|
- Use PostgreSQL enums or check constraints for status/type fields |
