Notes
tcdb sid 184226, "Total Cards: 20". THE DISTINCT SERIAL-TOKEN SET OF THIS TIER IS EXACTLY {SN10, SN9, SN7}, enumerated over all 20 rows in one fetch and NOT sampled: https://www.tcdb.com/Checklist.cfm/sid/184226/2017-18-Panini-Vanguard-Postseason-Heroes-Autographed-Materials-Gold. SN10 on 17 rows, SN9 on one (PH-CMX Cedric Maxwell) and SN7 on two (PH-BWL Bill Walton, PH-JKD Jason Kidd). ⚠ PER-CARD VARIABLE RUN, SO print_run AND serial_numbered ARE BOTH UNKNOWN. The tier is PROVABLY serial numbered - every row carries an SN token - but the tokens disagree with each other, and migrations/003_parallels.sql (run_and_serial_agree) cannot express serial_numbered=yes with print_run=UNKNOWN, so the fact is carried here and in a gaps row instead. Writing the modal token would be a false sourced integer on the minority rows. EXTRACTION_SPEC 2.3. ⚠ A CEILING IS NOT A PRINT RUN, AND THIS IS THE PROOF: cardboardconnection writes "Gold #/10 or less" (https://www.cardboardconnection.com/2017-18-panini-vanguard-basketball-nba-cards). Writing 10 would have been FALSE on three of twenty rows, not merely unsupported. Both sources agree the tier is not flat. PH-KLV Kevin Love additionally renders EXCH on this tier. See gaps G-005. CHANNEL NOT ASSIGNED, DELIBERATELY. No source found in this build asserts channel EXCLUSIVITY for this product or for any tier of it. The two strongest statements anywhere are both PRESENCE statements in the sense of reference/caveats.csv CAV-010: Panini America's own blog says "On average, each hobby box of 2017-18 Vanguard Basketball (five cards per box, six boxes per case) will deliver four autographs and one base card or parallel." (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2017-18-vanguard-basketball-50-images/) and cardboardconnection says "Formerly a Pacific brand across several sports from the early 2000s, each Hobby box of the basketball product averages four autographs." (https://www.cardboardconnection.com/2017-18-panini-vanguard-basketball-nba-cards). Both describe what a hobby box CONTAINS; neither says the product is sold only through hobby. channel is therefore UNKNOWN with an EMPTY channel_basis and an EMPTY channel_confidence, which migrations/003_parallels.sql requires (basis_iff_channel_known rejects channel=UNKNOWN with channel_basis=unsupported). See gaps G-004.
