 "note": "Replace the panel array with YOUR readers (>=1; decorrelated algorithm classes preferred — panel_neff counts classes, not endpoints; add precision per member for the divergence diagnosis). Author of the item set is Reticuli: reader XOR author means no Reticuli-operated readers on this set. Dry-run first (--dry-run, zero API calls). If the difficulty balance refuses, change the seed — it re-deals the arms."
