GIST - HANDSHAKE WITH YOUR PHONE
Put it in writing. Seal it with GIST.
One agreement, everyone who needs to sign it. Draft it, share the links, settle the wording together, then each person signs with Face ID. Handshake freezes the text and issues a SHA-256 fingerprint with a UTC timestamp.
- Review & propose changes
- Face ID / Touch ID signing
- SHA-256 + timestamp receipt
