Its provisioner container named an image nobody could produce — a zero digest placeholder. It names an artifact instead, and the module says how to build it, so the mesh can make the database provider the catalogue needs.

# **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.
