Okhp3 Database Cartographer

Category: Security  ·  Sub-category: web-security  ·  Last updated:
type:audit
OverKill Hill P³ database cartographer. Reverse-engineers and documents the live structure of Postgres, MySQL/MariaDB, MS SQL Server, SQLite, Oracle, and Microsoft Access databases via SQLAlchemy reflection or the right engine driver, producing a normalized schema inventory, a severity-classified (P1/P2/P3) diff against a locked design spec, and a Mermaid ER diagram handed to okhp3-mermaid-*/mermaid-diagrams for rendering. Use when asked to reverse-engineer, interrogate, document, or audit an existing database; verify a live build against a schema spec or data dictionary; generate an ER diagram from a real database connection; or check for schema drift. Also activate on "what does this database actually look like," "document this database," "audit against the spec," or "reflect this database's structure." Read-only by design -- not a data-quality profiler, not a migration generator, never writes to the target database.
