Prototype · Mock evidence

A working pipeline, not a price guide.

This runs the Identify → Authenticity → Quality → Weight → Explain pipeline live, over a hand-built set of sample transactions per card. Nothing here calls a real marketplace yet — swap the evidence source for PriceCharting, TCGplayer or a submitted-sale feed once access is in place.

How this number was built

Identify → Authenticity → Quality → Weight → Explain — runs live against the ledger above, not a fixed lookup.

01
Identity
Match set, variant, language, grade — reject wrong-item matches.
02
Authenticity
Keep only events that appear to be completed, settled sales.
03
Quality
Remove statistical outliers, duplicates, relists (IQR pass).
04
Weighting
Weight qualified sales by source reliability and recency.
05
Explainability
Decompose confidence, surface every excluded record.
