Evidence integrity

Verify the files, then verify the claims.

This build includes a machine-readable manifest for 730 evidence files. Every row gives the exact relative filename, byte size, full 64-character SHA-256 digest, and UTC hashing time.

What a matching hash proves

A matching digest shows that the downloaded file is byte-for-byte identical to the file hashed for this manifest. It can detect later alteration or corruption.

What a hash does not prove

A hash does not establish who created a document, whether every statement is true, whether an allegation is proven, or whether a court or agency reached a legal finding. Those questions require source and context review.

This root is a build-generated consistency digest. It is not an independent timestamp, digital signature, notarization, or proof of when any file first existed.

Review standard

  1. 1. Identify the exact file.
    Match the relative filename and byte size.
  2. 2. Calculate SHA-256.
    Use a trusted local hashing tool on the downloaded file.
  3. 3. Compare all 64 characters.
    An abbreviation or partial digest is not sufficient verification.
  4. 4. Check provenance and context.
    Review the source, date, surrounding correspondence, and any agency or court disposition.
