ADR-0053 — Generate Prisma metadata at build time

Status: accepted

Context

Prisma 7's recommended prisma-client generator no longer exposes the full schema model through the generated client's runtime Prisma.dmmf value. Kavo needs primary-key, default, nullability, and relation metadata to derive its entity contract. Reaching into generated-client internals would make the adapter dependent on unstable implementation details, while compiling the schema inside the application would add a CLI/compiler dependency to runtime.

Decision

@kavo/prisma provides kavo-prisma-generator. Applications run it during prisma generate; it emits a typed metadata module from Prisma's generator protocol input. createInfrastructure and createPrismaKavo accept that generated metadata module through the metadata option. The runtime adapter does not import Prisma.dmmf, Prisma compiler packages, or generated-client internals.

Prisma 7 is the supported Prisma major. The generated client should use the prisma-client generator and a driver adapter, as recommended by Prisma 7.
