Turns the raw failure list into a worklist driven by understanding each rule,
not by chasing the count. Three categories: (A) genuine correctness bugs in
instance validation worth fixing (union restriction facets ~200, QName length
~36, regex Unicode blocks ~155, duration ordering ~50, particles/int facets);
(B) schema-for-schemas structural validity, the bulk of the 2467 invalid
schemas accepted, unimplemented by design and documented as a deliberate
exclusion; (C) arguable cases needing investigation. Records the evidence
sampled per cluster.
