Evidence archive

Contemporaneous material captured as it appeared, so that it can be relied on later.

Rule

Every item is saved as a dated PDF or image and recorded in manifest.md with:

Field Why
Date captured Establishes it was taken at the time, not reconstructed
Source URL or origin Lets anyone go back to it
SHA-256 hash Shows the file has not changed since capture
One-line description So the manifest can be read without opening anything

Generate the hash with shasum -a 256 <file> and paste it in. It costs one line per item and turns a folder of screenshots into a record whose integrity can be demonstrated.
