The triage mapped the forges' notification reasons onto the claw's
verdicts, but it co-evolves with the vocabulary, not with the claw:
a reason that enters it (Gitea's collapsed shape) needs a verdict in
the same change, and its tests pin the mapping against the
vocabulary's own types. It now lives in the integration crate as the
default classification; a consumer may reclassify on top. The claw
imports it like the rest of the forge seam.
