# Prisma Migration Structure

This project uses Prisma as the default data access layer.

Migration policy:

- Create schema changes with `pnpm prisma:migrate:dev --name <change-name>` after the final MySQL connection details are confirmed.
- Commit generated folders under `prisma/migrations/<timestamp>_<change-name>/migration.sql`.
- Run migration checks in deployment before starting the API.
- Keep raw SQL exceptional. If native SQL is required for performance or vendor-specific behavior, place it behind a Repository method and document why Prisma Client is not sufficient.

The first-stage schema is defined in `prisma/schema.prisma`; no live migration is executed until a local or staging MySQL database is explicitly provided.
