tardygrada vs martin-loop

tardygrada: Tardygrada is a programming language that compiles to MCP servers, where every value carries cryptographic proof of its creator, creation time, and integrity. It guarantees integrity via mprotect, SHA-256, ed25519, and BFT consensus (proven in Coq), provenance with signed metadata, and a full audit trail. However, it does not guarantee truth; it only ensures the value has not been changed, providing 100% proof even after 100 handoffs among agents.; martin-loop: MartinLoop is a governance layer for AI coding loops that enforces budget caps, verifier gates, rollback evidence, and audit trails. It prevents unbounded retries by stopping unsafe or uneconomical work before execution, providing visibility and accountability for autonomous coding agents.
