The public account of the south ventilation line relies on the fan register and the handwritten checks at each junction. A review of that source and the field notes finds a specific limit: the count can be repeated, but it does not include a canvas test strip that catches the draft at the last occupied junction.
Dara Vek checked the fan register and the handwritten checks at each junction against the field notes. The method is to start at the shift handoff, where an official total can lose its context; it confirms the entries, but not every interpretation attached to them. The comparison covers 20 air checks entered per shift; 17 appear in the prior file. No signed correction to either entry was present when this review closed.
Kora Ennet, ventilation mechanic on the south shift, said the source register was complete for its stated purpose. The office has not provided a separate measure for whether the new fan can support an added working face without weakening the old return route, so the public record cannot yet show which account is more representative.
The mill’s output plan assumes the new fan runs at full power; mechanics note that the return door still sticks on cold starts. The current record does not settle that disagreement. This report does not establish that either side misstated the evidence. It establishes that the published total is narrower than the conclusion being drawn from it.
The first implementation notes have been compared with the promise in the minutes. The entry belongs to the maintenance audit file at the South Ventilation Line beside the old ore pass. A loaded test will be repeated with the return door fitted to its replacement hinge. The next file should preserve the original entries and explain any change in method.
