Database Schema

Autentico uses a single SQLite database file. Schema versioning uses SQLite's built-in PRAGMA user_version. The current schema version is defined as SchemaVersion in pkg/db/migrations/migrations.go (currently version 7). Fresh databases run all migrations from scratch; existing databases run only pending ones. Migrations are applied automatically on startup by default, or can be applied interactively via autentico migrate.
