Debrief

Flight lines were drawn around exclusion zones exported from the operator’s CAD drawing.

Each finding carries the asset tag from the operator’s register, so the work order lands on the right piece of plant.

It reads our asset register, so a finding arrives as SGT1, not as a pin on a photo.
