jschoubben 87243bc524 Every module stands on a base the mesh built
The base was a digest typed in by hand, for an image nothing in the mesh could
produce — so the graph held edges pointing at it with no version on the far end,
and the one change that reaches every module at once could never be noticed.
It is a module now, and these edges resolve.

# 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.

# this module's own container runs. One image, because they are one module and share a client.
