• G-002 Pink Ice Prizm mega-box attribution rests on a single retailer product listing (midwestcards.com 'Mega Box (Pink Ice)'); Red Ice Prizm mega-box attribution rests on a single secondary-market (eBay) listing title. Neither confirmed by a checklist site.

• G-006 Rookie Variations set (14 cards) is single-source (cardboardconnection only); checklistcenter and beckett do not list it.
• G-007 Full 300-card checklist extracted from cardboardconnection.com; second source (checklistcenter.com) verified base set size and a 19-card spot check (including all key rookies), not all 300 rows.
• G-008 White Sparkle Prizm channel unknown; beckett's FOTL note lists only Blue/Gold/Green/Black Shimmer as FOTL exclusives, so White Sparkle placement (FOTL bonus vs other) is unverified.

• G-009 Insert and autograph card counts agree across cardboardconnection and checklistcenter, but checklistcenter's page may be derived from the same Panini sell-sheet; no independent third confirmation.
• G-010 Beckett lists release date as 'March 31, 2021 (subject to change)'; cardboardconnection agrees; no Panini primary source checked.
• G-011 Per-set parallel tier repair pass: left unannotated for Rookie Variations (tcdb.com Inserts.cfm has no entry at all for this photo-variation subset; no suffixed colour-parallel subsets found on any consulted source.)
• G-012 Sensational Swatches: 99 of a stated 100 card-by-card rows written. The 100th card (Mitchell Robinson, New York Knicks) is listed by sportscardchecklist.com and breakninja.com, but both of those number the set 1-100 with a display index rather than the printed SSW- code; no code-bearing source consulted (tcdb.com by-number/by-last-name/by-age orderings, sportscardspro.com, COMC, eBay) yielded his printed card number. Row omitted rather than guessed.
• G-013 Duplicate printed card numbers within autograph sets: Signatures SI-SKE is carried by both Shawn Kemp and Steve Kerr; Penmanship PE-MON by both Miye Oni and Monte Morris; Sensational Signatures SS-JWS by both Jerry West and James Wiseman. The SS-JWS collision is confirmed by two independent eBay listings ('#SS-JWS Jerry West' and '#SS-JWS James Wiseman'); the other two rest on tcdb.com alone (SI-SKE confirmed by a verbatim re-fetch of both rows). Left verbatim; a resolver must not treat (set_name, card_number) as unique for these sets.
• G-014 Emergent #16 and #20 both read 'Malachi Flynn / Toronto Raptors' on all four sources consulted (sportscardchecklist.com, breakninja.com, tcdb.com, cardsmithsbreaks.com retail). Either the set genuinely repeats him or all four derive from one Panini sell-sheet carrying the error; no scan-level source was found to settle it. Written as printed.
• G-015 Card-number semantics differ by set type in this release and the two most-used checklist sites disagree. The ten insert sets are numbered with plain integers (confirmed independently by COMC: 'Dominance #4 - Ja Morant', '#15 - Zion Williamson'). The eight memorabilia/autograph sets are numbered with letter codes (SI-, RS-, RP-, PE-, FBA-, FR-, SSW-, SS-), confirmed on eBay/COMC listings. sportscardchecklist.com and breakninja.com present 1-N display indices for the coded sets; those indices were NOT written. Any earlier or later pass that ingests 1-N numbers for these eight sets is wrong.
• G-016 Contradicts G-006: Rookie Variations (14 cards) is NOT single-source. sportscardchecklist.com (set-214477), breakninja.com and cardsmithsbreaks.com (hobby checklist) all list it, and an eBay listing prints '2020-21 Panini Prizm - Rookie Variation Deni Avdija #290 Fast Break Prizm (RC)'. tcdb.com still has no entry for it (consistent with G-011). G-006 left in place per the no-rewrite rule; this row records the newer evidence.
• G-017 Team-of-record disagreement on Fearless #2 Gary Payton: sportscardchecklist.com and breakninja.com print 'Seattle Supersonics', cardsmithsbreaks.com prints 'Oklahoma City Thunder'. Written as 'Seattle Supersonics' (2 of 3 sources).
• G-018 RETROACTIVE TRUNCATION SWEEP 2026-09-07. Sensational Swatches (99 rows vs sets.csv 100) was re-opened with tcdb Gallery.cfm?PageIndex on sid 264748. The set is NOT tail-truncated: the page states 'Total Cards: 100' and its last page (PageIndex=10, card indices 91-100) renders SSW-RJE, SSW-SDW, SSW-SER, SSW-SON, SSW-TBR, SSW-TMC, SSW-TRO, SSW-TTH, SSW-XAM and SSW-ZCL - every one of which is already stored. The single missing card therefore sits in the interior of pages 1-9 rather than past a truncation point, and isolating it needs a full nine-page membership diff that was not run in this pass. No rows were invented. Still open: 99 of 100.
