 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

+`ascending_row_id_sort_key` strategy writes toolset ordering values from row
+IDs so higher part rows can sort before lower rows in the toolset; the legacy
+`descending_row_id_sort_key` strategy remains available for repositories that
+already depend on it. Per-dataset policies such as `chest: fixed 0.00` can
+override the default. When `null_undiscovered_rows` is true, authored part rows
+without discovered model IDs are omitted from the collected row set so dense
+2DA output writes them as `****` null rows. Authored source ACBONUS values are

 Extraction is deliberately guarded because it writes source files from binary
 archives. `extract.archives` is a list of glob patterns relative to
