What the coverage said
- Visibility was 'patchy' when container ship hit oil tanker, investigators sayrutland-times.co.uk · 2025-04-03

- tier C: only a Wikipedia article, GDELT sub-vocabulary term, or social per-term query fired — not yet confirmed as a real maritime incident (Phase C naming/is_maritime_incident does that).
- naming step found more than one plausible cause in the headlines (alternatives: ['Cargo ship hits US tanker off US coast', 'Seafarer dies in Ningbo collision']) — attribution.confidence is low; label may be an honest compound
- coverage scored on title only (no excerpt) — measured ~8pp frame precision cost vs title+excerpt (docs/HANDOVER-incidents.md §2.3)
- coverage filtered to articles matching this incident specifically (6/219 kept) — see coverage.filter.terms
