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.

curl -sI "https://api.btcintel.io/v1/claims/att_20934?version=1" | grep -i etag# ETag: W/"4bb070d8032315d010d347df8f27d49434978284110acdf5dfd29699d307397b-gzip" curl -s "https://api.btcintel.io/v1/claims/att_20934?version=1" | jq -r .content_sha256# 4bb070d8032315d010d347df8f27d49434978284110acdf5dfd29699d307397b# the first 16 hex are the citation's: btcintel:attributions:20934@v1 sha256:4bb070d8032315d0

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.
