Cards 1-200, one continuous run. tcdb parent Total Cards "200" and Gallery.cfm page 20 of 20 ends at card 200 with no block past the base run; Errors.cfm on the parent returns "No errors or variations have been added for this set yet." so no variation set exists (https://www.tcdb.com/Checklist.cfm/sid/253172/2020-21-Panini-Certified). cardboardconnection: "200 cards"; checklistcenter: "200 Cards"; sportscollectorsdaily: "Certified delivers a 200-card checklist with 150 veterans and 50 rookies". Four sources agree. Card counts are distinct cards (EXTRACTION_SPEC 5.4 unit 1). [CORRECTED 2026-09-20: THE Errors.cfm SENTENCE QUOTED ABOVE IS NOT EVIDENCE AND THE CONCLUSION DRAWN FROM IT DOES NOT HOLD. Measured 2026-09-20 on tcdb sid 182809: Errors.cfm returns that identical sentence for a set whose own renderings carry UER on at least two cards (card 260 Mo Bamba, "UER: Statline says Undrafted, was actually drafted 6th", confirmed under &sort=0; card 67 Justin Jackson, "Career stat line is that of Kosta Koufos"). The endpoint returns the same string on a set that provably HAS errata and on one that appears not to, so it discriminates nothing and its silence is uninformative. WHAT SURVIVES: any claim here about base_set_size, about the base run being contiguous, or about no numbered block sitting past the base run, because those rest on the independent contiguous enumeration also cited in this note - the last rendered Gallery page, the empty page after it, and the per-row flag column. WHAT DOES NOT SURVIVE: the narrower claim that NO VARIATION SET EXISTS. A variation set renders as b-suffixed rows (101a/101b) that a base-run enumeration is not designed to surface, and Errors.cfm was the documented route to it, so that claim is now unsupported rather than disproved - it may still be true. Not re-fetched; recorded so it is not read as settled. See reference/caveats.csv CAV-020.]
