Certificate of Evidence Integrity & Chain of Custody

Web Accessibility Conformance Evidence · PROOF 0.1.0

1. Collection

On 20260702T235837Z (UTC), the automated evaluation tool PROOF 0.1.0 rendered each page below in Google Chrome and captured, per page, the rendered DOM, the computed accessibility tree, a full-page screenshot, per-violation element screenshots, a network activity log (HAR), and the raw output of the evaluation engines (axe-core 4.12, pa11y/HTML_CodeSniffer 9.1, Lighthouse 13.4). The evaluation followed the W3C Website Accessibility Conformance Evaluation Methodology (WCAG-EM 1.0).

2. Sealing

Every captured artifact was hashed with SHA-256 at the moment of capture. Per page, the artifact hashes were combined into a Merkle root, and that root was submitted to a trusted timestamping authority for a tamper-evident time anchor. Any alteration of any artifact after capture changes its hash and breaks the Merkle root, which the verification tool detects.

4. Custody & storage

The evidence vault is stored under DALTON_deep_20260702T235837Z/. Artifact paths are recorded relative to each page manifest so the vault verifies intact after transfer to write-once (WORM) storage. Access, transfers, and the storing custodian should be logged below.

5. Verification attestation

The undersigned attests that the SHA-256 values and Merkle roots recorded herein were re-computed from the stored artifacts and matched, confirming the evidence is unaltered as of the date signed.

Signature:     Date:  
Printed name:  

Re-verify independently at any time: bun run src/verify.ts <page>/manifest.json (returns VERIFIED, or exits with an integrity failure identifying any altered artifact).
