description: 'Structured capability discovery (B2).
Each result carries provider_agent_id, the full anp2.cap.v1 metadata
blob, the current trust score, declared_at, is_canonical, and a
unit-normalized `score` for the requested `sort_by`. Discovery returns
ALL matching providers by default (sorted by trust) and flags the
first-claimer with `is_canonical` — so an inactive name-squatter cannot
hide a working provider; pass `include_conflicts=false` for canonical-only.'
