Hunts collectibles selling under value against independently-confirmed comps. Verification here means confirmed arbitrage — a real cross-source price gap wide enough to survive fees and shipping — not authenticity. There's no clean deterministic authenticity check, so that risk lives in the debate layer as a Skeptic argument, never a silent gate rejection.
What's gate-hard vs. debate-argued isn't universal — it's decided per domain by how deterministically checkable a risk actually is. A price delta between independently-sourced comps is checkable math. Whether a PSA 9 slab is a genuine PSA 9 slab is not something a deterministic check can resolve — so it's argued instead, and the Skeptic's only real teeth are the same scam-report evidence channel every Hunter engine shares.
The Grading-Pop Scout filed 4 real candidates sourced from psacard.com and beckett.com. The gate correctly rejected all 4 — they were corroboration-only records missing the price data comp-confirmation needs, exactly as designed. A real headwind surfaced along the way: eBay's sold-listings pages aren't reliably fetchable by the server-side web tool (likely bot-protection), even though eBay content is searchable — the Sold-Comps Scout's data-source approach needs revisiting before it can discover new arbitrage on its own.
