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.

# amqp-ping's runtime: the tool runtime, carrying this module's compiled code.

#
|
|
# **Built from this module's own directory and nothing else.** The sdk and the tool runtime are not
|
|
# copied out of neighbouring checkouts — they are in the base image, which is published like any
|
|
# other artifact. That is what makes this buildable by the mesh 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 here
|
|
# would make the runtime's contents depend on what somebody last pushed under that name.
