Detection boundary

Trigger. Evening operational ramp reached 2,412 MW against a 2,385 MW reference.

A steeper ramp raises the quantity and speed of dispatchable response required as rooftop solar output falls away.

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