# Database Audit
Audit a database layer — schema, queries, migrations, and the operational habits around them — for the design defects that surface as slow queries, silent data corruption, and unrunnable migrations in production. Read-only: it reports findings and a verdict; it never edits schema, data, or code. Works from the repo's schema files, migrations, and query sites; a live connection is optional and read-only when present.
**Evidence, not taste.** Every finding cites its artifact — a `file:line` in a migration or model, a query site, a schema definition, an `EXPLAIN` output if a connection exists. A "smelly" table name is a lead; confirm the defect (the missing constraint, the unindexable predicate) before flagging.
Four audit tracks — run the ones in scope:
- **A. Schema design** — types, keys, and the anti-pattern catalog.
- **B. Query patterns and indexes** — what the code asks, and whether an index can answer it.
- **C. Integrity and concurrency** — constraints, transactions, locking strategy.
- **D. Migrations and operations** — evolution, restore path, seeds, pooling.
## Scope and method
1. **Establish scope** — the whole schema, one domain's tables, or the migration history. Name it; findings without a boundary don't prioritize.
2. **Locate the source of truth** — schema files, ORM models, migration directory; note the engine and version (Postgres/MySQL/SQLite behave differently and some findings are engine-specific — say which).
3. **Read schema before
