Start with the stone-load register and the night watch’s closure notices. It is the source used to make a decision about whether the fourth arch can carry trade carts while repair stones are brought up the same road; it is not the decision itself. The rule only works if the source describes the conditions at the Seven Arches crossing above the east ravine.

The latest count is 18 loaded crossings; the prior file listed 19. The affected crew has tried the revised procedure under ordinary working conditions. The difference is a signal to check, not a verdict about who is right.

The disputed point is practical: The inspector’s limit protects the oldest span; carriers say the alternate route adds a full stair and a second toll. One side relies on the posted total, while the other points to a pale repair seam beneath the fourth arch, visible from the lower path.

The risk of reading the file too broadly is that an entry becomes a conclusion. Tavi Orr checked the stone-load register and the night watch’s closure notices against the field notes. The method is to trace a system from its control gate to the last household it is meant to serve; it confirms the entries, but not every interpretation attached to them.

Next: The masons will place a temporary measure stone before authorizing the next heavy load. A useful update will publish the method, exceptions and review date with the number.
