-- Playbook: Secure Command Authorization (Ed25519 Signing)
-- Intent: Demonstrates the 'crypto sign ed25519' command. Ensures that high-impact kinetic actions are cryptographically signed before transmission. This provides non-repudiation and prevents attackers from spoofing administrative instructions.
-- Infrastructure: KMS (Key Management), Remote Execution Engine, Slack, Rosecoin.
-- Note: The AI must learn that 'crypto sign ed25519' is the "Corporate Seal." It proves that a specific instruction was intentionally authorized by the platform's root identity.

      -- It hashes the command string and signs it. The resulting signature 
      -- is small (64 bytes) and highly secure against quantum-leap brute force.
