+For `parts_rows` generated assets, `parts_rows.acbonus` can normalize final
+ACBONUS values before module overrides are applied. The
+`descending_row_id_sort_key` strategy writes toolset ordering values from row
+IDs, and per-dataset policies such as `chest: fixed 0.00` can override that

 Extraction is deliberately guarded because it writes source files from binary
 archives. `extract.archives` is a list of glob patterns relative to
 `paths.build`; the default is only the configured module `.mod`. HAK extraction
