Kora Ennet carries a narrow canvas strip to the last occupied junction on the South Ventilation Line. On a warm run it lifts cleanly toward the return. On a cold start, the strip barely moves until Ennet pushes the return door past a point where its hinge catches.
The difference is easy to miss at the fan. The mill register records how much air the new fan moves at the intake; Ennet’s handwritten checks follow the path back through each occupied passage. A stronger intake can improve the first number while leaving the return uncertain at the old ore pass.
Ennet does not describe the sticking door as a failure. She calls it a condition that has to be reproduced and corrected before the extra working face is counted in the ventilation plan. The crew has marked the door’s cold-start position and asked for a loaded test after the hinge is replaced.
At the East Seam, workers are waiting on a separate rock reading. The two reviews have the same practical limit: one promising instrument result cannot clear a crew when another part of the route has not yet been checked.
