Prisma applies updatedAt in the client, so writes from raw SQL leave the timestamp stale

The updatedAt attribute is not a database trigger or a column default. Prisma sets the value in the UPDATE statement it generates, so any write that bypasses the client, an executeRaw statement, a psql session, another service, or a database-level cascade, leaves the timestamp at its old value.

The same applies to default uuid and default cuid, which are generated in the client rather than in the database, so the migration produces a column with no DEFAULT and a direct INSERT fails on the not-null constraint. default now and default autoincrement do become real database defaults. Read the generated migration SQL rather than assuming which is which. When rows must be written from outside Prisma, add the database default yourself in a migration, or use dbgenerated so Prisma records it in the schema.
