> This guide started as a migration helper. Backend `integrate-main-into-development@cab0719` now contains the first Postgres implementation layer: Drizzle schemas/migrations through `0008`, `src/db/client.ts`, `id_map`, `pg_dualwrite_gaps`, repository implementations/factory, backfill/verify scripts, conditional `payment_quotes` persistence, and aligned purchase/template request budget validation. The broad service layer is still Mongoose-first and is **not** fully wired through those repositories. Use [[Postgres Runtime Cutover Status]] as the authoritative current-state snapshot.
