Agent identity is all the rage bait debate right now. But it’s not hard really.
The agent's identity isn't a username or a UUID assigned by an IAM system. It's the hash of what it is: config, model, toolset, prompt. Change any of those and you have a different agent. The hash proves it.
So:
• NHI → machine_hash config_hash
• Session binding → every checkpoint signed with the operator's Ed25519 key, chained to the previous hash
• JIT tokens → the checkpoint IS the token — scoped to one decision, one moment, one signed state

Agent identity is unsolved and everyone needs it.
Right now agents have no identity. They borrow the operator's credentials, share API keys, leave no cryptographic trail of who did what. The 6-pillar framework calls it out as Pillar 1 but has no answer for how to actually implement it for agents — just "give each one a unique account" which is a human-IAM concept bolted onto something fundamentally different.
The hash-as-identity model solves it natively:
• Zero new infrastructure — identity emerges from what the agent already is
• Tamper-evident by construction — change the config, change the identity
• Auditable without a central authority — verify the chain yourself

You don't need a separate IAM layer. The proposed attestation chain IS the identity system. Every action is cryptographically bound to the agent state that took it.

French people are skinny because they exist on black coffee and nicotine and one meal a day and their food is not toxic.
It's Analog GLP1.
Prove me wrong.
