Open-source 2-of-3 policy-enforced threshold HSM: auto-signs cold→hot treasury refills under on-device Coldcard policy, no human in the loop. Includes the full operator manual + quick-start, the reference coordinator/signing code, and a signer-host bootstrap. No keys, seeds, or secrets — placeholders only. Live signet demo: https://multisighsm.mineracks.com Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
