Review Summary

What survived the funnel

Open this run to answer one question: is this real attacker-relevant behavior with real impact, or just normal contract plumbing?

Review Checklist
1. Read the findings table first. Ignore raw jobs until the result looks real.
2. Confirm attacker control, not just the existence of a sink.
3. Confirm money or privilege impact.
4. Keep it if the behavior is real. Kill it if this is normal proxy, admin, or upgrade plumbing.
