atlas-auditing

Use when asked to audit, review, QA, or health-check a Graphite Atlas, or before signing off on a process build, or when inheriting an atlas copied from production. Runs a fixed set of read-only checks, as AtlasQL SQL through query_atlas with run_audit and the read tools as the fallback, that detect violations of the Atlas modeling patterns (dependencies at the wrong level, resources pointing at artifacts or vendors, orphaned step membership, steps with no performer, system/vendor names baked into nodes, overloaded part_of, orphan Data Tables, execution-mode contradictions). Reports findings; does not mutate.
