DB schema migrations you can trust your agent to write.

Migratrom turns schema changes into typed, self-verifying operations for PostgreSQL and SQLite. Write migrations in your application language, prove each change, and keep applied history tamper-evident.

## Why Migratrom?

### Typed, not textual

Schema changes are typed values in your language, not SQL files with hand-written up/down scripts. Refactor and review them like any other code.

### Idempotent by construction

Every operation carries a postcheck: a boolean SQL probe that proves whether the change already exists. Re-running a migration batch is always safe.

### Tamper-evident history

A SHA-256 checksum is stored with each applied migration. Editing the body of an already-applied migration is rejected with no silent drift.

### DAG ordering

Migrations form a parent/child graph. The engine validates the graph and applies pending migrations in dependency order.

### Multi-runtime

JavaScript supports Bun, Node, and Deno. Swift supports Swift 6.2+ with PostgresNIO or SQift. Same concepts, idiomatic implementations.

### Multi-dialect

PostgreSQL and SQLite ship built in. Dialect selection is always explicit, so you always know which SQL you're generating.
