Classifies each statement of a PostgreSQL, MySQL or SQLite migration (up to 20000 characters) as reversible, needing a backup, needing the original definition, or irreversible, for agents that write or review schema migrations. Flags DROP TABLE/COLUMN, TRUNCATE, unbounded DELETE/UPDATE, lossy type changes, NOT NULL or constraints that fail on existing rows, table-rewrite and lock hazards, and MySQL's non-transactional DDL, with a mechanical inverse statement where one exists. Tokenizer-level: it does not know the table's row counts or contents, runs nothing, and returns unsupported for statement forms it does not classify.
