Notes

FULL-ROW TOKEN SWEEP, never a sample (CAV-050): every rendered row's flag column was read and the DISTINCT token set recorded. 18 of 18 rows read and CONFIRMED ROW FOR ROW ON TWO DIFFERENTLY-VARIED FETCHES because this row decides a rule: https://www.tcdb.com/Checklist.cfm/sid/154896/2016-17-Panini-Grand-Reserve-Legendary-Cornerstones-Marble?sort=0 and https://www.tcdb.com/ViewSet.cfm/sid/154896/2016-17-Panini-Grand-Reserve-Legendary-Cornerstones-Marble . tcdb states "Total Cards: 18"; the rendered numbers are 1-20 with 7 and 16 absent. DISTINCT TOKEN SET {AU, MEM, SN5, SN8, SN10}: sixteen rows read SN10, card 11 reads "AU, MEM, SN5" and card 17 reads "AU, MEM, SN8", quoted back identically by both endpoints. A THREE-ROW SAMPLE HERE WRITES A CLEAN, SOURCED-LOOKING FLAT 10 - and so does Panini's own copy, which says "Marble (numbered to 10)" with NO "or less" qualifier (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/) and is therefore WRONG about this tier. UNKNOWN/UNKNOWN per EXTRACTION_SPEC 2.3; census in G-012. source_confidence `single` - tcdb is the only source that renders this tier at all. 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.
