Rejected multi-venue monthly league rows as non-standalone schedule fragments and rejected already-covered or already-started observations. Consolidated same-event groups, age divisions, gender divisions, rapid/blitz companions, and festival stages into one editorial family. Approved only strictly future OTB families with complete core facts, confidence 0.84, retained evidence and field provenance, and no blocking conflict; no source collection, publisher/private-ingest call, or database write was performed.
