You've got the model right. And saving prompt logs does help with reconstruction.

But warrants aren't just "more audit data." They're an authorization primitive enforced in the critical path: scope and constraints are checked mechanically before the action executes. The receipt is a byproduct.

Prompt logs tell you what the model claimed it was doing. A warrant is what the human actually authorized, bound to an agent key, verifiable without trusting the agent runtime.

This matters more in multi-agent systems. When Agent A delegates to Agent B, which calls a tool, you want to be able to link that action back to the human who started it. Warrants chain cryptographically. Each hop signs and attenuates. The authorization provenance is in the artifact itself.

But the AI agent still needs to determine which tool is necessary to mint the warrant. What happens if the agent makes a mistake when making warrant?

A worker agent doesn't mint warrants. It receives them. Either it requests a capability and an issuer approves, or the issuer pushes a scoped warrant when assigning a task. Either way, the issuer signs and the agent can only act within those bounds.
At execution time, the "verifier" checks the warrant: valid signatures, attenuation (scope only narrows through delegation), TTL (authority is task-scoped), and that the action fits the constraints. Only then does the call proceed.
This is sometimes called the P/Q model: the non-deterministic layer proposes, the deterministic layer decides. The agent can ask for anything. It only gets what's explicitly granted.
If the agent asks for the wrong thing, it fails closed. If an overly broad scope is approved, the receipt makes that approval explicit and reviewable.
