Notes

FULL-ROW TOKEN SWEEP, never a sample (CAV-050): every rendered row's flag column was read and the DISTINCT token set recorded. 40 of 40 rows carry the identical token string, confirmed on TWO differently-varied fetches: https://www.tcdb.com/Checklist.cfm/sid/154904/2016-17-Panini-Grand-Reserve-Cornerstones-Marble?sort=0 and https://www.tcdb.com/ViewSet.cfm/sid/154904/2016-17-Panini-Grand-Reserve-Cornerstones-Marble , the second asked per row with no summarising and asked specifically to name any card whose token is not SN10, answering "NONE DIFFER". DISTINCT TOKEN SET {AU, MEM, SN10}. Two independent non-tcdb sources state the figure WITHOUT an "or less" qualifier - Panini's own blog "Marble (numbered to 10)" (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/) and cardboardconnection "Marble #/10" (https://www.cardboardconnection.com/2016-17-panini-grand-reserve-basketball) - so source_confidence is `multi`. NOTE the same wording is NOT true of the sibling Marble tiers of Legendary Cornerstones and Rookie Cornerstones, which are variable (G-012). CHANNEL: hobby with basis `sourced-presence`, NOT exclusivity. The statement is PRODUCT-LEVEL - Panini's own blog says "each hobby box of 2017 Grand Reserve Basketball" (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/), cardboardconnection says "three hits per hobby box" and gives one single configuration, "8 cards per pack, 3 packs per box, 8 boxes per case" (https://www.cardboardconnection.com/2016-17-panini-grand-reserve-basketball), and blowoutbuzz gives one SRP for the same pack (https://blowoutbuzz.wordpress.com/2017/05/16/first-buzz-2016-17-panini-grand-reserve-basketball-cards/). No source consulted names a retail, blaster, mega or international SKU for this product, and no source claims exclusivity, so presence is the strongest claim the evidence supports and it is applied at product level rather than per tier. See G-010.
