  "summary": "Static review of Python database access and transactions (SQLAlchemy, Django ORM, DB-API): session and transaction scope, commit/rollback boundaries, N+1 and lazy-loading, connection-pool sizing, migration safety, and multi-tenancy scoping. Reads source, models, and migrations only; never connects to a database or runs a migration.",

  "security_notes": "Static review only — reads ORM models, query code, session/engine configuration, and migration scripts to assess transaction and data-access correctness; never opens a database connection, runs a query, or applies a migration. A claim about actual query counts, lock behavior, or migration runtime is flagged as needing measurement against a real database. Never requests connection strings, database credentials, or customer data.",
