The public account of the furnace breath relies on the furnace heat marks and the crew’s pause-and-return log. A review of that source and the field notes finds a specific limit: the count can be repeated, but it does not include a soot line on the draft door that shifts when the intake starts to narrow.
Maela Dorn checked the furnace heat marks and the crew’s pause-and-return log against the field notes. The method is to follow the task through a complete shift, including the cleanup after the bell; it confirms the entries, but not every interpretation attached to them. The comparison covers 21 cooling pauses per completed charge; 21 appear in the prior file. No signed correction to either entry was present when this review closed.
Mera Doss, first smelter on the north furnace crew, said the source register was complete for its stated purpose. The office has not provided a separate measure for whether the new fuel mix can cut smoke without requiring a longer hot shift, so the public record cannot yet show which account is more representative.
The mill measures fuel by charge; the crew says time spent clearing a slow draft is missing from that total. 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 affected crew has tried the revised procedure under ordinary working conditions. The entry belongs to the field review file at the north furnace aisle in the communal ironworks. The next trial will record both charge time and the minutes spent clearing the intake. The next file should preserve the original entries and explain any change in method.
