SIGMABUS is a working draft for safety-critical, edge-native coordination. Do not deploy this repository as an autonomous control authority without an independent hazard analysis, integration review, and physical override path.

Open a private security advisory or contact the repository owner before publishing vulnerabilities that affect identity, signing, trust calculation, authority delegation, replay prevention, or control handback.

• Human override remains inalienable.
• All CM messages are expected to be signed by conformant implementations.
• Messages below the effective trust floor must not be acted on.
• Local configs contain placeholders only; never commit production credentials, private keys, vessel identifiers, or operational logs.
