01 / Operational model
Who acts, and what changes?
Principal and authority origin
A maintenance scheduler acting for an authorized utility team. Approved work package and named operator delegation.
Consequential action
Create a switching work order or request a substation maintenance window.
02 / Action-time control
Make the requested effect testable.
Asset, circuit, outage window, crew presence and system-operator clearance. Deny a work-order change outside the approved circuit and hold any switching command for operational interlock.

03 / Evidence and responsibility
Permission, execution, and outcome are separate.
Work package, clearance reference, evaluated asset, decision and control-room acknowledgement.
ProofGrid can model and record the digital authority check; it cannot replace grid safety procedures or a SCADA interlock.
