ScopeProof by Davisville Labs
Authorization before action

Know whether the agent is actually allowed to do it.

ScopeProof checks one proposed machine action against one explicit authority envelope, then returns a deterministic decision and tamper-evident receipt. Global, machine-native, privacy-minimized.

ScopeProof does not infer authority from a prompt and never executes the proposed action. It evaluates only explicit structured constraints supplied by the caller. Credentials and secret-like material are rejected.
