Filed INSIDE the parent checklist as cards 101-110 with no sid of its own (EXTRACTION_SPEC 5.3 hidden-block pattern); every row flagged "AU, RC, SN99" and, unlike 111-150, carrying no MEM. cardboardconnection heads it "Rookie Autographs Set Checklist" and states "10 cards. Serial numbered #/99."; checklistcenter renders the same block as "2018-19 Panini Impeccable - Rookie Auto Set" at 10 cards. Excluded from base_set_size. Note cardboardconnection and checklistcenter are ONE editorial lineage (CAV-033), so the count outside tcdb is effectively single-source; the 10-card extent is independently confirmed by the tcdb parent's own flag boundary at 110/111. https://www.tcdb.com/Checklist.cfm/sid/192094/2018-19-Panini-Impeccable?PageIndex=2 ; https://www.cardboardconnection.com/2018-19-panini-impeccable-basketball-nba-cards ; https://www.checklistcenter.com/2018-19-panini-impeccable-basketball/
