Detection boundary

Trigger. Minimum operational demand reached 649 MW against a 692 MW reference.

Lower registered demand increases the need to manage system strength, essential generation and the midday-to-evening transition on an isolated grid.

This is a deterministic measurement flag. It does not assign causality, estimate commercial exposure or claim the operating outcome was unsafe.
