You can now download the Evidence Bundle sample

We have received your request. This sample recreates an ordinary U.S. case: a home remodel where, months later, the contractor tries to justify an overrun with a change order, a revised takeoff and a new photo that look doubtful and appear AI-generated or AI-altered.

Downloadable file Backend-generated U.S. remodel dispute sample

This ZIP is now emitted by the HREVN backend runtime. It contains the original package sealed at project start. The later disputed files - a change order with a revised takeoff and a suspicious justification photo - are described in the README, but they are deliberately outside the original sealed package.

What is inside
  • Contract and scope of work
  • Original contractor estimate v1
  • Existing floor plan
  • Initial takeoff spreadsheet
  • WhatsApp screenshot with the original delivery
  • 3 pre-work photos
  • Scenario README
  • manifest.json, CHECKSUMS.sha256, ROOT_HASH_SHA256.txt, ROOT_SPEC_EB1.txt and BLOCKCHAIN_ANCHOR.json
Important:

This sample is fictional and shows the structure of an original sealed package. HREVN does not by itself certify whether the later spreadsheet or photo are true: it helps prove that they were not part of the original package if they appear later.
