## arch
Linear and branched migration history using Alembic's revision system with merge points to reconcile divergent branches; migrations use declarative SQLAlchemy operations with defensive idempotent checks, conditional existence guards, dialect-specific handling (PostgreSQL/SQLite), and in-place data migrations for template/schema evolution.
