# Prisma governance

## Single source of truth

- Canonical Prisma schema: `frontend/prisma/schema.prisma`.
- Service copies:
  - `omni_chat/prisma/schema.prisma`
  - `omni_outbound/prisma/schema.prisma`

## Update flow

1. Edit only `frontend/prisma/schema.prisma`.
2. Run `./scripts/prisma-sync.sh`.
3. Run `./scripts/prisma-check.sh`.
4. Commit changed schema copies.

## Rollout policy

- Schema rollout (`prisma db push` / migrations) is allowed only in `frontend`.
- `omni_chat` and `omni_outbound` must use generated Prisma client only.
