 - Schema changes are forward-only in production. Destructive migrations require a dedicated maintenance window and an explicit plan.

+- **Agentic contributors working in a project with a Postgres dependency will usually have MCP access to a Postgres MCP server scoped to that project's database(s).** Prefer using the MCP server to inspect schema, verify query shapes against real tables, and sanity-check migrations before applying them — don't guess at column names or types when you can look them up. The scope is limited to the project's own databases; don't assume access to unrelated ones.
 
 ### Distributed database: Turso
 When the app's data model is distributed (edge replicas, per-site local copies with sync), use Turso. Auth via Turso-issued tokens stored in the per-host secret store, not in `manifest.yml`.
