Mera Doss opens the furnace heat marks and the crew’s pause-and-return log at the north furnace aisle in the communal ironworks. Before anyone moves a cart or changes a mark, the crew checks a soot line on the draft door that shifts when the intake starts to narrow. The grain fall air brings its own pace to the passage.

The latest page holds 69 cooling pauses per completed charge. Mera Doss reads the previous count (69) before the next mark is made. It is a small pause, long enough for the people at the rail to hear what the number leaves out.

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. The difference between those accounts is visible here: a rule on the board and a working condition just beyond it.

A field check has compared the written rule with the place where it is used. The entry belongs to the follow-up survey file at the north furnace aisle in the communal ironworks. The next check will be made by another crew, asked to repeat the measure without borrowing the first crew’s conclusion.

When the shift closes, the file remains beside the marked place. The next trial will record both charge time and the minutes spent clearing the intake. Until then, the route, schedule or allotment stays as it was at the opening bell.
