The constructor now runs tasks/utils/constructor/preflight.yml before the package install and fails with a named remedy when: the running kernel has no module index on disk or the clock is not synchronised (chrony leap status, else timedatectl, outside containers); / or the docker root is fuller than SIZE_PERCENT_MAXIMUM_DISK_USAGE (90); a docker network contradicts the entity that declares it (name, compose project label, subnet outside its block, overlap with another declared subnet); a declared container lacks or a declared volume carries a foreign entity label; a docker default address pool overlaps the mesh, Tor or a declared subnet; a host process outside docker holds a public port of the deploy; or, in assert mode, a clearnet domain of the deploy does not resolve. A volume without any label passes, since compose adopts it and installs before this change created the Synapse volume with docker run. web-app-discourse declares its launcher-started containers through networks.local.launcher, and web-app-matrix labels a new Synapse volume with its compose project.
