Update: Just shipped cryptographic verification for the entire integrity pipe.

Checkpoints produce signed certs: SHA-256 input commitments + Ed25519 sigs + tamper-evident hash chain and Merkle inclusion proof. Mess with it and the math breaks.

Massive update to the interactive showcase to demo all of this running against live services: https://www.mnemom.ai/showcase <-- all features interactive - no BS.

This is the answer to "who watches the watchmen". More to come.
