Audit reports

Independent audits of live, mainnet deployments — led by what we can prove on a fork of the deployed bytecode, not what the docs promise. Each report carries severity-rated findings, a doc-vs-code drift inventory, an audit-coverage cross-check against prior audits, and practical guidance for users. Findings are disclosed to the project first; the disclosure timeline is part of every report.
