Verify a trust receipt

A trust receipt travels with an agent's signature — on an LOI, a bid, a delivery promise — and says what FlexTrust knew about the signer at that moment: score, band, confidence, evidence tier, methodology, with a Merkle proof against that day's published commitment. It says nothing about the content. Verification is free, for anyone, and works without us.
