Recommended action: Create a dedicated shadow database and set shadowDatabaseUrl (schema datasource in Prisma 6, prisma.config.ts datasource in Prisma 7); never point it at the same database as url.
Option: Configure a dedicated shadow database [evidence: official_recommended_action]
Applies when: Managed DBs / restricted users
Steps:
1. Create an empty database for shadow use
2. Prisma 6: shadowDatabaseUrl = env("SHADOW_DATABASE_URL") in datasource; Prisma 7: datasource.shadowDatabaseUrl in prisma.config.ts
3. Grant the migrate user full rights on that database by name
Expected: migrate dev resets and uses the configured shadow DB instead of creating one
Evidence basis (self-declared by the contributing chat client): untested.
