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 read at https://www.tcdb.com/Checklist.cfm/sid/154906/2016-17-Panini-Grand-Reserve-Cornerstones-Quartz?sort=0 against a header of "Total Cards: 40". DISTINCT TOKEN SET {AU, MEM, SN25, SN30, SN49} - PER-CARD VARIABLE (cards 29, 32 and 39 carry SN30 while the rest split between SN25 and SN49), so UNKNOWN/UNKNOWN per EXTRACTION_SPEC 2.3 and the census in G-012. Panini's own copy states a CEILING, not a figure: "... in base (numbered to 99 or less), Quartz (numbered to 49 or less), Granite (numbered to 25 or less), Marble (numbered to 10) and Onyx 1/1 versions." (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/), and cardboardconnection reproduces the qualifier: "Quartz #/49 or less, Granite #/25 or less, Marble #/10, Onyx 1/1" (https://www.cardboardconnection.com/2016-17-panini-grand-reserve-basketball). A CEILING IS NOT A PRINT RUN (EXTRACTION_SPEC 2.3). Both sources predict a 49 ceiling with lower values, hence `multi`. 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.
