Query efficiency audit worker (L3). Checks redundant entity fetches, N-UPDATE/DELETE loops, unnecessary resolves, over-fetching, missing bulk operations, wrong caching scope. Returns findings with severity, location, effort, recommendations.

Transaction correctness audit worker (L3). Checks missing intermediate commits, transaction scope (too wide/narrow), missing rollback handling, long-held transactions, trigger/notify interaction. Returns findings with severity, location, effort, recommendations.

Runtime performance audit worker (L3). Checks blocking IO in async, unnecessary allocations, sync sleep in async, string concat in loops, missing to_thread for CPU-bound, redundant data copies. Returns findings with severity, location, effort, recommendations.

Resource lifecycle audit worker (L3). Checks session scope mismatch, streaming resource holding, missing cleanup, pool config, error path leaks, factory vs injection anti-patterns.
