Irregular's block catalog fills a private plate per part type, and that fill searched best-fit pairs through the overload that ignores the token. On one CPU the search can take minutes, so a time limit waited for it: the converted Nestbolt m-public-gear-1 job under a 60 s limit ran past 180 s. PrivatePlateFill now passes its token, as PairCatalog does since 9431006e; the search still finishes in the background and fills the shared cache. gear-1, Irregular, one CPU, 60 s limit: killed after 180 s -> stops at 60.0 s (no layout yet; its no-fit polygons are the next bottleneck).
