migraguard

PostgreSQL-first, schema-aware deployment control with LLM agents and deterministic CI gates. v0.16.12 — active development, frequent releases (weekly + hotfixes). Key differentiators: 38 AST-based lint rules, tamper detection without a DB connection (offline), regression detection on hotfix reverts, drift detection with shadow DB verification, and LLM-powered 'implement'/'audit'/'explain' commands that encode domain expertise into migration files. Supports MySQL and SQLite with 17 generic lint rules. Uses native CLI (psql/mysql/sqlite3) for execution; focuses on what to forbid rather than a rich execution engine.
