Verifythe hash of what is served must begin with the citation's 16 hex

A citation names a claim, a version and the first 16 hex of that version's content hash. Fetch the version and compare: the hash must begin with the citation's 16 hex. The ETag of the answer carries the same hash: production answers it weak (W/) and with its encoding's suffix (-gzip), or bare.

Every change to the content writes a new version with its own hash; the previous version keeps its hash and its citation, so a quote never changes under the reader.
