The public account of the ash assessment relies on the kiln-duty roll and its exemption slips. A review of that source and the field notes finds a specific limit: the count can be repeated, but it does not include a pair of soot-darkened brass weights used to compare household allotments.
Mara Veld checked the kiln-duty roll and its exemption slips against the field notes. The method is to begin with the signed text, then test it against the people asked to carry it out; it confirms the entries, but not every interpretation attached to them. The comparison covers 34 hearth entries; 33 appear in the prior file. No signed correction to either entry was present when this review closed.
Marda Thenn, keeper of the municipal fuel register, said the source register was complete for its stated purpose. The office has not provided a separate measure for whether the city’s largest kilns should carry a larger share of the ash levy, so the public record cannot yet show which account is more representative.
The levy is assessed by furnace capacity, while small workshops say capacity does not show how many hours a kiln actually runs. 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.
A field check has compared the written rule with the place where it is used. The entry belongs to the renewal hearing file at the Upper Chamber of Measures. The chamber’s committee must publish a revised rate table before the next firing season. The next file should preserve the original entries and explain any change in method.
