Pike, bowfin, snakehead: Jay 'looks good' 2026-09-18 10:12; muskellunge: Jay 'include' after Claude's check, 2026-09-18. SHA-256 verified against the approved packages. Batch 2 (13 close-ups: bass pair, six sunfish, crappie pair, three bullheads): Jay approved 11 on 2026-09-21 and the rebuilt largemouth + L. megalotis longear the same evening ('approve both'); an entry's 'states' limits the sites it appears on (warmouth and longear are Indiana-only). Ontario (Jay, 2026-09-22 'add the close-ups to the Ontario fish guide'): the bass pair, bluegill + pumpkinseed (the only sunfish Ontario's catch data and look-alike notes name; its longear is L. peltastes, not the L. megalotis drawn here), both crappies and all three bullheads (the Ontario page names black bullhead).",
