+# Database Workflow
+
+## Migrations
+
+- Raw SQL in `database/migrations/` — numbered files (e.g. `012_feature.sql`)
+- Apply: `./database/migrate.sh` or `docker exec` into `meshkee-postgres`
+- Docker auto-runs migrations only on **first** Postgres volume init
+
+## After schema change
+
+```bash
+npm run prisma:pull
+npm run prisma:generate
+```
+
+Never edit `prisma/schema.prisma` without a corresponding SQL migration (except post-pull formatting).
+
+## Conventions in SQL
+
+- `set_updated_at()` triggers on mutable tables
+- `BIGINT GENERATED BY DEFAULT AS IDENTITY` for PKs
+- Foreign keys with explicit `ON DELETE` (Cascade for owned data, Restrict/SetNull where appropriate)
+- Seed permissions in the same migration when adding new resources
+
+## Prisma relations
+
+Keep relation names aligned with existing schema style. `businessId` maps to `business_id`, enums use `@@map` for snake_case DB names.
