// Canonical schema barrel. Repositories import their tables from here and the
// provider-aware `db` from "@/db", so each repository is written ONCE for both
// backends.
//
// The TYPE identity is the SQLite definitions; the runtime VALUES are whichever
// provider is active. `schema-parity.test.ts` asserts the two dialect schemas
// are structurally interchangeable (same tables/columns/nullability/PKs/unique
// indexes), which is what makes the single cast below sound. The Postgres
// schema is the one structural artifact NOT regenerated by `db:generate`, so the
// parity test is its drift guard.
