// zero-sample-sweep — READ-ONLY, $0. Cycle 68 (DTD-picked A, unanimous).
// Sizes the c67 P1 by the OFFICER-SPECIFIED SIGNATURE across vendors:
//   single-variant + variant title ~ "Sample" + price == $0.00 + available==true
//   = an orderable $0 sample = free-checkout exposure (the RL bug, 111 found in c67).
// METHOD: (Phase 1) discovery scan of the reachable global /products.json (Shopify
// caps unauth at page 100 = ~25k of ~74k → coverage caveat NAMED), classify by signature,
// GROUP affected by vendor. (Phase 2) for each affected vendor, page its full
// /collections/<handle>/products.json for the COMPLETE per-vendor count (reaches products
// beyond the 25k cap). Secondary bucket: single-variant "Sample" at a non-$0/non-$4.25
// price (mis-seed in other directions). NEGATIVE CONTROL: count a healthy multi-variant
// priced product as NOT-defect + reproduce RL in the affected-vendor list.
// EXCLUDES Phillip Jeffries.
