Verified Asset checks a second-hand listing's claims ("set of 4 chairs", "white", "no visible damage") against the seller's own photos and gives buyers a report before they make the trip. The seller writes or dictates the claims, takes only the photos those claims need (with the listing's code on paper), and gets a report link to paste into the listing; buyers open it without signing up.

Muse Spark 1.3 describes each photo blind, never seeing the claims; fixed Python rules decide whether each claim is supported, contradicted or can't be settled from photos; SAM 3.1 gives a second-opinion count and boxes damage; when a photo can't settle a claim, Spark plans the one missing shot and marks it on the seller's photo. The report is bound to the listing version and each photo's hash, so editing the listing voids it, and missing evidence is never turned into reassurance.

Second-hand buying runs on trust buyers cannot check: the US FTC reported on 27 April 2026 that reported losses to scams that started on social media reached $2.1 billion in 2025, with more money lost to scams that began on Facebook than on any other platform. Verified Asset does not claim to stop fraud; it makes the seller's words checkable.

Built during the hackathon (Oct 27 to Nov 4) on top of a disclosed research prototype; what is new is in the repo's provenance record. Live: https://verified.adwentech.com · Code: https://github.com/cpu-16/verified-asset
