Notes

FULL-ROW TOKEN SWEEP, never a sample (CAV-050): every rendered row's flag column was read and the DISTINCT token set recorded. 49 of 49 rows carry the identical token string, confirmed on TWO differently-varied fetches: https://www.tcdb.com/Checklist.cfm/sid/154886/2016-17-Panini-Grand-Reserve-Reserve-Signatures-Marble?sort=0 and https://www.tcdb.com/ViewSet.cfm/sid/154886/2016-17-Panini-Grand-Reserve-Reserve-Signatures-Marble . tcdb states "Total Cards: 49"; rendered numbers 1-50 with 41 absent on both endpoints, reconciling to 49. DISTINCT TOKEN SET {AU, SN10}; the second fetch was asked to name any card whose token is not SN10, answering "NONE DIFFER", and to list any empty flag column, answering none. NOTE this tier omits card 41 while its sibling Granite tier omits card 33 - the tiers are not nested. `single`: no non-tcdb source names this tier. 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.
