Against the published package (presidio-evidence 0.5.1, tag v0.5.1 = 2ab6905): the
first two files are byte-identical. In ed25519-golden.json only the "description"
text differs (the published copy names the consumers differently); every key,
message and signature is the same. tests/test_canonical_conformance.py checks both:
the code against these copies, and these copies against the installed library's
vectors, ignoring "description".

Do not edit these files. If presidio-evidence publishes new vectors, copy them in as
new files and update this note.
