A public-safe walkthrough of the control boundary between model intelligence, policy, authority, approval, action, execution evidence, and evaluation.
The model may analyze and propose. Its output does not create permission.
Independent governed records determine whether a proposed action is permitted and within scope.
Claims of execution are reconciled against receipts, outcomes, and append-only evidence.
Model consensus can increase confidence. It cannot create authority.
This case study intentionally omits private implementation details, complete internal registries, and exploitable security configuration.
