• G-004 Insert counts for Luck of the Lottery (15), NBA Finalists (10) and Widescreen (10) are single-source (checklistcenter.com only); cardboardconnection page truncated before these sections.
• G-005 Relationship between 'Base Signatures' (192 cards) and 'Signatures' (60 cards) unclear; the 192-card figure may be a combined autograph checklist. Both sources list both entries identically.
• G-006 checklistcenter.com parallel/insert lists are word-for-word identical to cardboardconnection.com; corroboration may not be independent (possible mirrored content).
• G-007 rookie_flag=no for cards 1-247 inferred from absence of RC tags in source checklists; RC tags were explicitly shown only for cards 248-300.
• G-008 Card #176 initially extracted as duplicate 'Frank Ntilikina'; resolved as Emmanuel Mudiay (Utah Jazz) via verbatim cardboardconnection quote and checklistcenter.com agreement.
• G-009 White Sparkle Prizm is commonly described in the hobby as a Premium FOTL exclusive, but no consulted source confirmed this; channel left UNKNOWN.

• G-010 Per-set parallel tier repair pass: left unannotated for Base Signatures (tcdb.com Inserts.cfm listed 'Base Signatures' with no suffixed colour-parallel subsets (unlike every other insert/auto set on the page); relationship to 'Signatures' already flagged in G-005.)
• G-011 Penmanship checklist written with 55 of the 56 cards in sets.csv. https://www.tcdb.com/Checklist.cfm/sid/221253/2019-20-Panini-Prizm---Penmanship lists 55 rows (its own stated Total Cards is 55) with printed PM-* codes; https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ lists 56 players, the extra being Mitchell Robinson. No source consulted printed a card number for the Mitchell Robinson card, so the row was omitted rather than given an invented PM- code.
• G-012 Signatures checklist written with 54 of the 60 cards in sets.csv. https://www.tcdb.com/Checklist.cfm/sid/221280/2019-20-Panini-Prizm---Signatures lists 54 rows with printed SG-* codes; https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ lists 60 players. The six with no sourced printed code are Harry Giles, Isaiah Thomas, Felipe Lopez, Kyrie Irving, Julius Erving and Cuttino Mobley. Rows omitted rather than numbered by guess.
• G-013 Fast Break Autographs written with 59 of 60. Both https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ and https://www.tcdb.com/Checklist.cfm/sid/221247/2019-20-Panini-Prizm---Fast-Break-Autographs include a Kobe Bryant card, but tcdb prints its card number as the placeholder 'TBA' rather than an FB- code. 'TBA' is not a printed card number, so the row was omitted rather than written with a placeholder or a guessed code.
• G-014 Sensational Swatches written with 68 of the 100 cards in sets.csv, covering codes SS-AAG through SS-LBJ. https://www.tcdb.com/Checklist.cfm/sid/220818/2019-20-Panini-Prizm---Sensational-Swatches is the only source found that carries the printed SS-* codes, and its page content is cut off by the fetch pipeline partway through the alphabetical run; the set is a single tcdb page so pagination could not reach the remainder. https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ has all 100 players but renumbers them 1-100, which is not what is printed on the card. The ~32 remaining rows need a source that prints the codes.
• G-015 Sensational Signatures written with 72 of the 100 cards in sets.csv, covering codes SS-AAD through SS-MJN. Same cause as Sensational Swatches: https://www.tcdb.com/Checklist.cfm/sid/221268/2019-20-Panini-Prizm---Sensational-Signatures is the only code-bearing source and its content is truncated partway through the alphabetical run. Note tcdb states its own Total Cards as 98, not 100, so the true set size is also unconfirmed. https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ lists 100 players but renumbers them 1-100.
• G-016 Two duplicate printed card numbers transcribed verbatim from tcdb and believed to be source errors, not real: FB-TYG appears on both Thaddeus Young and Trae Young in https://www.tcdb.com/Checklist.cfm/sid/221247/2019-20-Panini-Prizm---Fast-Break-Autographs, and SS-DGR appears on both Danny Green and Devean George in https://www.tcdb.com/Checklist.cfm/sid/221268/2019-20-Panini-Prizm---Sensational-Signatures. Written as printed per the no-normalisation rule; each needs one code corrected against a second code-bearing source.
• G-017 Card-number scheme conflict across all code-numbered sets in this release. https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ and cardboardconnection.com renumber Penmanship, Rookie Penmanship, Signatures, Rookie Signatures, Fast Break Autographs, Fast Break Rookie Autographs, Sensational Swatches and Sensational Signatures as a plain 1..N sequence; tcdb.com prints letter codes (PM-, RP-, SG-, RS-, FB-, FR-, SS-). The codes were taken as the printed card number after marketplace listings for the Zion Williamson Sensational Swatches card showed '#SS-ZWL'. This was checked on one card only; the other seven sets' schemes are inferred from the same tcdb convention.
• G-018 Three single-field team conflicts between sources, resolved by majority and recorded in the row's notes rather than silently picked: Fireworks #9 Kyrie Irving (Brooklyn Nets per https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ and this release's own base_cards.csv, Cleveland Cavaliers per tcdb); Rookie Penmanship RP-JXH Jaxson Hayes (New Orleans Pelicans per checklistcenter and sportscardchecklist.com, Atlanta Hawks per tcdb - Atlanta was his draft-night team before the trade); Penmanship PM-OPJ Otto Porter Jr. (Washington Wizards per tcdb, Chicago Bulls per checklistcenter) where the sources are 1-1 and tcdb was used as the card_number source.
• G-019 Positive finding against G-004, recorded without altering that row. G-004 flags the counts for Luck of the Lottery (15), NBA Finalists (10) and Widescreen (10) as single-source (checklistcenter.com only). All three are now independently corroborated card-for-card by tcdb.com: https://www.tcdb.com/Checklist.cfm/sid/220811/2019-20-Panini-Prizm---Luck-of-the-Lottery, https://www.tcdb.com/Checklist.cfm/sid/220814/2019-20-Panini-Prizm---NBA-Finalists, https://www.tcdb.com/Checklist.cfm/sid/220815/2019-20-Panini-Prizm---Widescreen. tcdb also names the third set 'Widescreen', matching our sets.csv spelling, against checklistcenter's 'Wide Screen'. G-004 looks closeable by a human reviewer.
• G-020 Luck of the Lottery card 15 is a group/class card, not a player card. https://www.tcdb.com/Checklist.cfm/sid/220811/2019-20-Panini-Prizm---Luck-of-the-Lottery prints it as 'Class of 2019'; https://www.checklistcenter.com/2019-20-panini-prizm-basketball-card-checklist/ prints it as '23 Player Group Photo' (confirmed by a narrow verbatim re-fetch of that single line). 'Class of 2019' was written as player_name with an empty team; the two source spellings are not reconciled.
• G-021 RETROACTIVE TRUNCATION SWEEP 2026-09-07. These insert/auto checklists were completed before tcdb's Gallery.cfm?PageIndex endpoint was known; Checklist.cfm truncates silently and stochastically, so short sets were recorded as complete. Re-opened all five partial sets with Gallery.cfm (paginates by card INDEX at 10/page and states the set total) and with Errors.cfm. RECOVERED: Sensational Swatches 68 -> 100 rows, reconciles EXACTLY against tcdb sid 220818 'Total Cards: 100' (pages 7-10); Sensational Signatures 72 -> 98 rows against tcdb sid 221268 'Total Cards: 98' (pages 8-10, page 10 renders 8 rows). NOT TRUNCATED, no rows invented: (a) Signatures - sid 221280 states 'Total Cards: 54' and page 6 renders 4 rows (5x10+4=54), card-for-card identical to our 54 stored rows; sets.csv says 60, so 6 cards are absent from tcdb entirely, not withheld by truncation. (b) Fast Break Autographs - sid 221247 states 'Total Cards: 60'; page 6 renders our final 9 codes plus a literal 'TBA - Kobe Bryant'. Errors.cfm renders that row as 'TBA Kobe Bryant AU, EXCH', i.e. an exchange/redemption card with no catalogued printed number. 59 written + 1 unwritable = 60. (c) Penmanship - sid 221253 states 'Total Cards: 55' and page 6 renders 5 rows (=55), identical to our 55; sets.csv says 56, so 1 card is absent from tcdb. UNRESOLVED: Sensational Signatures is 98 against sets.csv's 100 (tcdb's header and its rendered row count agree at 98); Signatures 54 vs 60; Penmanship 55 vs 56. team_or_school is EMPTY on all 58 rows added here because Gallery.cfm renders no team and no second source was read for it; the card_number and player_name are fully sourced.
