# The release channel: a v* tag ships the exact-version images (plus
# the sha pin the chart's appVersion resolves to) and the exact-version
# chart. Edge publishing on every main push lives in ci.yml. Release
# candidates (a v* tag with a prerelease suffix, v0.2.0-rc1) publish
# nothing. The daemon crate itself is `publish = false`, so no
# crates.io leg runs here: the crates the claw pulls live in the rhema
# repository's release channel.
