2023-24 Mosaic

• G-001 Hobby release date disagreement: Beckett.com/news lists June 26, 2024 (flagged 'subject to change'); ChecklistInsider and CardLines both list August 7, 2024. Used 2024-08-07 (2-source majority). Needs confirmation from a shipping/street-date source.
• G-002 Blue Mosaic print run disagreement: BreakNinja reports /99 while ChecklistInsider, CardLines and cllct.com all report /199. Used /199.
• G-003 No source publishes RC designations for this release, so rookie_flag is UNKNOWN for all 300 cards. Cards 201-250 are labelled 'Base Rookies' and 251-270 'Base NBA Debut' by two sources, but neither prints an explicit RC marker.
• G-004 Card #135 OG Anunoby is listed with two teams by CardsmithsBreaks (New York Knicks and Toronto Raptors), suggesting an unconfirmed photo/team variation. ChecklistInsider and eBay listings both show New York Knicks; used Knicks. The possible Raptors variation is unverified.
• G-005 No source publishes card counts for ANY of the 17 non-autograph insert sets (Storm Chasers, Overdrive, Razzle Dazzle, Heat Check, In-Season Tournament, Stained Glass, Micro Mosaic, Bank Shot, Stare Masters, Notoriety, Introductions, Montage, Elevate, Jam Masters, Epic Performers, Thunder Road, Give and Go). All recorded as UNKNOWN.
• G-006 CardLines lists hobby inserts 'Men of Mastery', 'Splash', 'Straight Fire' and 'Swagger' for this release; four other sources (ChecklistInsider, Beckett, gogts.net, CardsmithsBreaks) omit them entirely. Likely carryover text from prior Mosaic years - excluded from sets.csv pending confirmation.
• G-007 Autograph counts unstable within a single source: ChecklistInsider returned Autographs Mosaic 54 / Fast Break 95 / Collage 35 / Pictographs 37 in one pass and 60 / 100 / 35 / 40 in another. Used the 54 / 95 figures (corroborated by CardsmithsBreaks); Collage 35 and Pictographs 37 remain single-source.
• G-008 ChecklistInsider lists 'Autographs Mosaic Choice' (53), 'Autographs Mosaic International' (49), 'Collage Autographs Mosaic Choice' (33), 'Collage Autographs Mosaic International' (31) and 'Pictographs Mosaic Choice Autographs' (35). Unclear whether these are distinct sets or channel parallels of the base autograph sets; omitted from sets.csv to avoid double-counting.

• G-010 White Sparkle Mosaic channel inferred from retail pack listings on eBay only; no checklist source states which SKU it comes from. Recorded as 'retail' with single confidence.

• G-011 The International family (International, Red /75, Blue /25, Gold /10) and the FOTL Swirl family (Pink /18, Green /3) are single-source (ChecklistInsider). Channel for International recorded as 'hobby' (international hobby boxes) - not independently confirmed.

• G-012 cardboardconnection.com - the spec's primary source - returned ROBOTS_DISALLOWED on every fetch attempt, so its checklist and print-run data could not be used. tcdb.com and beckett.com full checklists were likewise unavailable (Beckett article returned only summary prose with base set size 'TBA').
• G-013 The full 1-300 base checklist comes from CardsmithsBreaks; ChecklistInsider was used only as a spot-check (cards 130-140, 200, 250, 300 all matched). Cards outside those spot-checked ranges are effectively single-source.
• G-014 Retail-exclusive autograph counts (Scripts 60, Rookie Scripts 40) are single-source (CardsmithsBreaks); the sets' existence is confirmed by retail blaster box product descriptions but the counts are not.
• G-015 "Storm Chasers": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-016 "Overdrive": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-017 "Razzle Dazzle": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-018 "Heat Check": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-019 "In-Season Tournament": no sourced own-parallel-tier colour list found for this non-base set. tcdb lists this only as "NBA In-Season Tournament" with no colour suffixes; checklistcenter documents no parallels line either.
• G-020 "Stained Glass": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-021 "Micro Mosaic": no sourced own-parallel-tier colour list found for this non-base set. Neither tcdb Inserts.cfm nor checklistcenter.com documents a colour tier for this set.
• G-022 "In-Focus Signatures": no sourced own-parallel-tier colour list found for this non-base set. Not found on tcdb's Inserts.cfm page or on checklistcenter.com for this release under this or any similar name.
• G-023 "In-Focus Signatures": no card-by-card checklist could be sourced, and the set itself could not be corroborated. tcdb has no set of this name for any product (Search.cfm returns none) and it is absent from the release Inserts.cfm listing at https://www.tcdb.com/Inserts.cfm/sid/433006/2023-24-Panini-Mosaic . The only source, cardlines.com https://cardlines.com/2023-24-mosaic-basketball-checklist/ , is speculative rather than a checklist - it reads verbatim "Possible autograph sets could include In-Focus Signatures, Rookie Autographs and Showtime Signatures." No rows written; sets.csv card_count is UNKNOWN. The set name itself may be unconfirmed.
• G-024 "Rookie Autographs Mosaic": 34 of the 38 rows tcdb renders were written. tcdb repeats the single code RA-CBY on FOUR different players on both https://www.tcdb.com/Checklist.cfm/sid/457385/2023-24-Panini-Mosaic-Rookie-Autographs-Mosaic and its Black parallel https://www.tcdb.com/Checklist.cfm/sid/457386/2023-24-Panini-Mosaic-Rookie-Autographs-Mosaic-Black . RA-CBY was written only for Colby Jones, the one player it can belong to. WITHHELD (number not sourceable): Dariq Whitehead, Dereck Lively II, Hunter Tyson. That these three carry distinct codes in sibling sets of the same release (FB-DRQ / FB-LIV / FB-TYS in Autographs Fast Break; RS-LIV / RS-TYS in Rookie Scripts) shows RA-CBY is a tcdb data-entry smear, but their true RA- codes are not sourceable and were NOT derived. ALSO WITHHELD: Kobe Brown, whose card number tcdb stores as the literal string TBD. sets.csv card_count is UNKNOWN; 38 rows rendered.
• G-025 "Collage Autographs Mosaic": 33 of the set's 35 cards were written. tcdb stores the literal string TBD as the card number for TWO players on both https://www.tcdb.com/Checklist.cfm/sid/457344/2023-24-Panini-Mosaic-Collage-Autographs-Mosaic and its Black parallel https://www.tcdb.com/Checklist.cfm/sid/457345/2023-24-Panini-Mosaic-Collage-Autographs-Mosaic-Black . WITHHELD: Dejounte Murray, D'Angelo Russell. The Black parallel renders 35, matching sets.csv card_count 35, so the roster is complete and only these two numbers are missing.
• G-026 "Autographs Fast Break": 94 of the set's 95 cards were written. WITHHELD: Luka Doncic, whose card number tcdb stores as the literal string TBD on both https://www.tcdb.com/Checklist.cfm/sid/470554/2023-24-Panini-Mosaic-Autographs-Fast-Break and its Black parallel https://www.tcdb.com/Checklist.cfm/sid/470555/2023-24-Panini-Mosaic-Autographs-Fast-Break-Black . Base Checklist.cfm truncated at 77 rows of 93 (counted by hand; the page's own row-count claim was wrong); indices 71-93 were recovered via Gallery.cfm?PageIndex=8/9/10, and the Black parallel supplied FB-AGB and FB-COL, which the base page omits entirely, bringing the total to 95 = sets.csv card_count.
• G-027 "Showtime Signatures": 24 coded rows written. WITHHELD: Luka Doncic, whose card number tcdb stores as the literal string TBD on both https://www.tcdb.com/Checklist.cfm/sid/457359/2023-24-Panini-Mosaic-Showtime-Signatures-Mosaic and its Black parallel https://www.tcdb.com/Checklist.cfm/sid/457366/2023-24-Panini-Mosaic-Showtime-Signatures-Mosaic-Black . sets.csv card_count is UNKNOWN; the base page renders 23 and the Black parallel 25 (adding SS-ALL Grayson Allen and SS-MNK Malik Monk), so 25 is the best-evidenced size. tcdb names this set "Showtime Signatures Mosaic"; ours is "Showtime Signatures".
• G-028 "Scripts": 59 of the set's 60 cards were written. WITHHELD: Patty Mills, whose card number renders on https://www.tcdb.com/Checklist.cfm/sid/453285/2023-24-Panini-Mosaic---Scripts as the bare ordinal "41" on a page where all 59 other rows carry an MS- code. Its row id sorts into alphabetical position for "Mills", so the printed code is probably an MS- form, but that is an inference and no source prints it, so the number was NOT derived. 60 rendered rows = tcdb Total Cards 60 = sets.csv card_count 60.
• G-029 Genuine duplicate card numbers written verbatim and flagged in this release, per spec (chase_cards is unique on set+number+player, not set+number): "Pictographs Mosaic Autographs" PM-KEY on both Keldon Johnson and Keyonte George; "Rookie Scripts" RS-KEY on both Keyontae Johnson and Keyonte George (on all four of its pages); "Autographs Fast Break" FB-WHT on both Coby White and Colby Jones. Each survived a re-read of a second tcdb page for the same set. Recorded here so a later pass does not mistake them for import errors. Distinct from the RA-CBY smear in G-024, which was judged a source error and withheld.
• G-030 Card counts resolved for sets whose sets.csv card_count is UNKNOWN, from tcdb rendered rows (counted by hand, not from page self-reports): Storm Chasers 20, Overdrive 25, Razzle Dazzle 15, Heat Check 15, In-Season Tournament 25, Bank Shot 20, Stare Masters 20, Notoriety 10, Introductions 20, Montage 30, Elevate 25, Jam Masters 20, Epic Performers 20, Thunder Road 20, Give and Go 15, Rookie Autographs Mosaic 38, Showtime Signatures 25. sets.csv is not writable by this task, so these are recorded here for a later pass. Confirmed counts matching sets.csv already: Autographs Mosaic 54, Pictographs Mosaic Autographs 37, Collage Autographs Mosaic 35, Autographs Fast Break 95, Scripts 60, Rookie Scripts 40.
• G-031 tcdb subsets listed under this release's parent sid 433006 that have NO row in our sets.csv and were deliberately not written: (a) sid 460981 "2023-24 Panini - Private Signings" - a cross-brand Panini signing program that tcdb files under this parent; per spec its cards belong to whichever product they were pulled from and must not be cross-written into this release. (b) sid 457363 sits inside the otherwise contiguous Showtime Signatures run 457359-457367 and redirects to the tcdb homepage - i.e. the sid exists but renders no cards, so it is an empty set rather than a missing one. (c) sid 466051 "Bank Shot Mosaic" sits far outside the 455642-455651 Bank Shot island; it is a parallel tier, not a new set. Sid-block boundaries were confirmed by probing: 450650 and 450660 return genuine 404s while the identical slug shape resolves on live sid 450645, and 457393 resolves to a different product entirely ("2023-24 Upper Deck - Triple Exposure Achievements"), so the Mosaic run ends at 457392.
