2025-26 Cosmic Chrome

• G-002 Print run disagreement on the two SKU-exclusive parallels. cardsmithsbreaks prints "FDI 1 Refractor #/8-#/12 (1:662)" and "Lunar Refractor #/10 (1:764)", implying serial numbering (and a variable /8-/12 range for FDI). checklistinsider, checklistcenter and the official Topps odds sheet show odds only with no serial numbering for either. Recorded as unnumbered on the 3-source majority; unresolved.
• G-003 Rookie flag disagreement on card #30 Stephon Castle and #52 Zaccharie Risacher: cardsmithsbreaks lists both with an RC designation, checklistinsider does not. Both players debuted in 2024-25, so an RC logo in a 2025-26 product is doubtful. Recorded as UNKNOWN pending a third source.
• G-004 Release date disagreement: checklistinsider, checklistcenter, topps.com and steelcitycollectibles give a 2026-04-29 hobby street date (FDI 2026-04-28); blowoutcards "First Buzz" gives 2026-04-30. Recorded as 2026-04-29 on the majority.
• G-005 Purple Nebula Refractor print run: checklistinsider, ripped.topps.com and cardsmithsbreaks show /150; checklistcenter shows /149. Recorded as 150 on the majority.
• G-007 beckett.com/news returned HTTP 403 on every attempt (https://www.beckett.com/news/2025-26-topps-cosmic-chrome-basketball-cards/), so the Beckett checklist could not be used to cross-check set names or counts.
• G-008 cardboardconnection.com has no page for this release (URL pattern /2025-26-topps-cosmic-chrome-basketball-cards fails to resolve), so the spec's highest-priority source was unavailable for this product.
• G-009 Insert set name spelling varies by source and no source is authoritative: Planetary Pursuit / Planetary Pursuits; StarFractor / Starfractor; Re-Entry / Re Entry; Hypernova / Hyper Nova; Propulsion / Propulsions; Electro Static Signatures / Electro-Static Signatures; Cosmic Chrome Autographs / Cosmic Chrome Autograph Variations. Canonical Topps spellings unverified.
• G-010 Card #44 is printed as "Alperun Sengun" by both cardsmithsbreaks and checklistinsider; the player's name is normally rendered Alperen Sengun (Alperen Sengun/Sengün). Both sources appear to share the same upstream Topps checklist file, so the misspelling may be on the card itself. Recorded as printed.
• G-011 checklistcenter's rendering of the base checklist lists both Nikola Jovic and Darius Garland at #101, implying a numbering conflict. cardsmithsbreaks and checklistinsider both place Jovic at #48 and Garland at #101 with a clean contiguous 1-200 run; recorded on the 2-source agreement.
• G-012 Card counts for Hypernova and Cosmic Dust come from checklistinsider and checklistcenter only (20 each); cardsmithsbreaks names both sets but publishes no checklist or count for them, calling them ultra-rare case hits. Geocentric's count (30) likewise comes from checklistinsider and checklistcenter only.
• G-013 No base-card photo-variation or short-print variation set could be confirmed. cardsmithsbreaks states no distinct SP variation set exists beyond the parallel structure, while ripped.topps.com refers to "Cosmic Chrome Autograph Variations" - treated here as the autograph set name (Cosmic Chrome Autographs), not a separate base variation set. Unresolved.
• G-015 Planetary Pursuit is recorded as a single 100-card insert per checklistinsider and cardsmithsbreaks, but ripped.topps.com describes it as ten planet-named tiers (Mercury through Pluto) with tier-specific odds. Whether the ontology should model it as one set or ten is unresolved.
• G-016 PER-SET PARALLEL TIERS: 10 of 17 non-base sets carry an enumerated tier note. The remainder returned NO dedicated parallel section on checklistinsider, the only source that calibrated cleanly for Topps products; a sample was confirmed absent by targeted per-name query rather than inferred from silence. Many appear to be plain unnumbered inserts that genuinely have no ladder. NOTE the source landscape here differs from Panini: tcdb's Inserts.cfm page, which carried this data for every Panini line, is NOT validated for Topps, and ripped.topps.com's Collector's Guide was caught FABRICATING a full rainbow ladder that a verbatim search disproved. Resolving further needs a first-party Topps odds sheet per product, not more scraping.
