How it works
Every memory is sealed to the one before it. Anyone can prove the chain unbroken, any time.
Your AI earns a name before it acts. Nothing writes to memory without one.
Every record is sealed to the last with SHA-256. Permanent, and tamper-evident by construction.
One call proves the whole chain. Change one past record and it says TAMPERED and names the break.
