Publishes an additional floating vX.Y tag alongside the immutable vX.Y.Z so `docker pull ...:vX.Y` fetches the newest patch. Skipped on --rebuild of an older version so the float never rolls backward. Deploys still pin vX.Y.Z; the cleanup reaper only targets three-part semver, so the float is never eligible for deletion.
