  # The release channel. `courier deployed` appends a version to the document
  # releases/hush.prod (the changelog, `git log <serving>..<this>`) and posts one
  # message on the `deploys` topic, as the `releases` agent, whose credential can
  # send and do nothing else. The same call every other substrate makes — see
  # orchard9-k3sf scripts/lib/release.sh; this is the Woodpecker copy.

  # The CLI comes out of courier's own image, pinned by digest, pulled with the
  # bare OCI protocol (zot allows anonymous pulls): the image is distroless and
  # the k8s backend runs steps through /bin/sh, so neither the image itself nor
  # crane:debug (/busybox/sh only) can be the step — measured on pipeline 10.
