Documents the focused security review of the protocol-versioning migration and the cargo-deny policy addition. Result: no high-confidence vulnerabilities — the versioned_topic XOR transform is entropy-preserving, signature binding uses the raw topic_id consistently, and the ALPN/domain changes are handshake-level compatibility only.
