# postgres's runtime: the tool runtime, carrying this module's compiled provisioner, tools and
# event consumer.
#
# **Built from this module's own directory and nothing else.** The sdk is in the base image, so
# nothing is copied out of a neighbouring checkout — which is what lets the mesh build this from a
# repository and a path (novox/hq ADR 0069) rather than only on a workstation that happens to have
# the siblings.
#
# The base is named by ARG so it can be pinned to a digest the mesh's registry assigned. A tag would
# make this runtime's contents depend on what somebody last pushed under that name.
