[Phantom8420]

Summary

• Clone detection: every product lookup is scored for the pattern a photocopied label leaves (many distinct networks scanning one code, or bursts of scans). Sold items are held to a stricter threshold. The API returns risk with the record; the product page shows a Scan risk meter and flags a likely clone. Source networks are hashed /24s, never raw IPs.
• Demo: in-browser mirror of the same scoring, with a "Simulate a cloned label" button on the demo item.
• Gas: contracts/test/Gas.ts measures each on-chain action (mint ~196k, stages ~47-64k, full life ~400k) and fails on regressions.
• Tests: +10 backend, +2 frontend unit, +1 e2e (clone flagged, restart clears it).

Notes

• It is a transparent statistical model, not a trained network; documented as such.
• Scan history is in memory (documented; Redis for multi-instance).
