The probe disagreed with the map.
Juno checked its seating at the accessible port, repeated the passive reading, and asked the local observer to read the value without looking at her sheet. The gradient ran opposite to the direction indicated by the old pressure plan. If they followed the existing entry assignment, Kellan would brace the wrong door and the actual retreat point would remain unprotected.
“No load on the brace,” she said.
Kellan held the ordinary equipment clear of the frame. The local builder looked at the port and then at the copied plan. She did not choose the paper because it was familiar or the instrument because it was new. She asked for the second mechanical indicator.
Pela obtained its reading from the safe local position. It agreed with the probe’s direction. The current gradient was not the one the plan assigned to that visible label.
Ilyan opened the later repair note the operator had requested.
The work had reversed the visible inspection labels while leaving the copied pressure plan unchanged. The label at the accessible port now named the opposite branch from the one Juno had expected. The hidden connection itself could not be fully inspected from the approach, but the repair note and two current indications established enough to reject the old entry assignment.
