• G-002 Release date disagreement: tcdb.com and steelcitycollectibles.com list 12/3/2021 and gogts.net says 'early December, hobby on the 3rd'; cardlines.com's product review states 2021-09-17 and dacardworld.com lists 12/15/2021 for the Choice box. Used 2021-12-03.
• G-003 No source found displays explicit RC logos/designations. rookie_flag=yes was assigned to 201-245 solely because two sources (breakninja.com, sportscardchecklist.com) label that block the 'Rookies' subset. NBA Debut (261-280) and the five 2020-21 rookies inside National Pride (252, 257, 258, 259, 260) are UNKNOWN.
• G-004 Team assignments come from checklistcenter.com / sportscardchecklist.com / breakninja.com, which appear to share a data feed and reflect roster updates rather than as-printed teams (e.g. #3 Nemanja Bjelica listed as Miami Heat, #11 Troy Brown Jr. as Chicago Bulls, #59 Nikola Vucevic as Chicago Bulls). Teams are unverified against card images.

• G-016 Scripts card count disagreement: checklistcenter.com says 59; sportscardchecklist.com parallels range 57-59. Used 59.
• G-017 sportscardchecklist.com lists an additional 15-card entry spelled '2020-21 Panini Mosaic Mosiac Genesis (15 Cards)', separate from the 300-card Mosaic Genesis parallel. Could not determine whether this is a distinct insert set, a Genesis parallel of a 15-card insert, or a data-entry error; excluded from sets.csv.
• G-018 Insert set counts come from checklistcenter.com and sportscardchecklist.com only; no third source could be reached to confirm. Center Stage, Overdrive, Stained Glass, Straight Fire and Swagger are described as hobby-exclusive by dacardworld.com but this was not independently confirmed.
• G-019 Rookie Private Signings (2 cards: Association Version, Icon Version) is single-source (checklistcenter.com / sportscardchecklist.com, which appear to share a feed).
• G-020 "Center Stage": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-021 "Overdrive": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-022 "Rookie Variations": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm does not list this set at all under this release.
• G-023 "Stained Glass": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-024 "Straight Fire": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-025 "Swagger": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-026 "Rookie Private Signings": no sourced own-parallel-tier colour list found for this non-base set. tcdb only lists this family as two separately-suffixed products ("...Association Version" / "...Icon Version"); neither name matches our row exactly, so the correct mapping is ambiguous.
• G-027 "Scripts": card_count disagreement. sets.csv records 59; tcdb.com renders 60 rows and its Gallery.cfm range line states "of 60" (https://www.tcdb.com/Checklist.cfm/sid/291886/2020-21-Panini-Mosaic---Scripts , https://www.tcdb.com/Gallery.cfm/sid/291886/2020-21-Panini-Mosaic---Scripts?PageIndex=6). All 60 rows were written to insert_cards.csv verbatim, including a genuine duplicate code SC-BBR printed on two different cards (Brent Barry and Bruce Brown), which may be why one source counts 59. sets.csv was not altered.
• G-028 "Rookie Variations" (14 cards) is not catalogued by tcdb.com at all - absent from Inserts.cfm for parent sid 277474 and no sibling-parent listing found. Roster of 14 players taken from cardsmithsbreaks.com (a roster-only source under the spec): Anthony Edwards, LaMelo Ball, Tyrese Maxey, Tyrese Haliburton, James Wiseman, Patrick Williams, Cole Anthony, Immanuel Quickley, Payton Pritchard, Desmond Bane, Isaac Okoro, Deni Avdija, Obi Toppin, Onyeka Okongwu. The numbering scheme is BASE-MIRRORED and was confirmed on two cards from marketplace evidence: https://www.ebay.de/itm/267459146671 ("Rookie Variation Anthony Edwards #201 Fast Break Silver Prizm") and https://www.comc.com/Cards/Basketball/2020-21/Panini_Mosaic_-_Base_-_Silver_Fast_Break_Prizm/2032/Rookie_Variation_-_Tyrese_Maxey/17972543/Graded/PSA/9 (#203.2). The remaining 12 card numbers were taken from each player's base Rookies card number in this release's base_cards.csv under that confirmed scheme; they are NOT individually sourced from a listing and should be re-verified card by card.
• G-029 "Overdrive": tcdb.com's Checklist.cfm header claims "Total Cards: 30" but only 25 cards exist - Gallery.cfm?PageIndex=3 ends with the range line "21 to 25 of 30" (https://www.tcdb.com/Gallery.cfm/sid/291870/2020-21-Panini-Mosaic---Overdrive?PageIndex=3). 25 rows written, matching sets.csv card_count 25. tcdb's stated total is stale; the rendered rows were trusted.
• G-030 "Autographs Fast Break": tcdb Checklist.cfm truncates silently at 50 of 100 rows (https://www.tcdb.com/Checklist.cfm/sid/291794/2020-21-Panini-Mosaic---Autographs-Fast-Break). Cards 51-100 were recovered from Gallery.cfm pages 6-10, which render card number and player but NOT team, so team_or_school is empty for those 50 rows. Codes and players are complete (100 of 100).
• G-031 Count disagreements recorded in sets.csv notes are now settled against tcdb rendered rows: "Stare Masters" renders 25 (sets.csv 25, checklistcenter.com's 20 is wrong) and "Rookie Scripts" renders 40 (sets.csv 40, sportscardchecklist.com's 38 is wrong). sets.csv was not altered; recorded here so the disagreement notes can be closed on a later pass.
• G-032 [DEMOTED 2026-09-03] Rookie Variations: 12 of 14 rows have been REMOVED from insert_cards.csv. The extracting agent stated plainly in its own notes that these card numbers were DERIVED -- each player mapped to their base Rookies number under an assumed base-mirrored scheme -- and not individually sourced. Only 2 of the 14 carried marketplace evidence (#201 Anthony Edwards, #203 Tyrese Maxey); those two are RETAINED. tcdb has no page for this set under any parent, so the roster came from a roster-only source and the numbering scheme itself is an inference from two datapoints. The spec requires evidence or omission, and this project has already deleted 30 rows on Flawless for an inference of exactly this shape (a sibling set that mirrored player-for-player), a refusal later proven correct when the mirror turned out not to hold. The hole at 209 is mild evidence the mapping is real rather than sequential fill, but mild evidence is not evidence. ROSTER PRESERVED -- the numbers below are the DERIVED mapping and must not be treated as printed card numbers: 202 LaMelo Ball; 204 Tyrese Haliburton; 205 James Wiseman; 206 Patrick Williams; 207 Cole Anthony; 208 Immanuel Quickley; 210 Payton Pritchard; 211 Desmond Bane; 212 Isaac Okoro; 217 Deni Avdija; 220 Obi Toppin; 225 Onyeka Okongwu. TO RESOLVE: one free-text seller title per card (eBay /itm/, goldin /item/, fanaticscollect buy-now, or a comc CARD page whose URL segment is the number -- NOT an eBay /p/ page). Two were found already, so the rest are findable.
