Tyler Roberts and the verification layer
A systems developer documents a behavioral-health EHR, an audit engine, and the verification methods used to decide when software is actually finished.
Field notes
The portfolio describes an EHR with three portals, iOS and Android applications, ordered signatures, signer-specific records, and a hash chain linking each signature to the previous one. Its verification harness treats execution evidence as the standard: checkers read outputs, guards are mutation-tested, and refusals must trigger a corresponding control. The page also names 33 document templates and reports 110 checkers supporting the broader system.
