# 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.
#
# Two bases, named rather than pinned: the image this is COMPILED in, and the image it RUNS in.
# They are different images on purpose — the first carries a compiler and the second must not, or
# every running container would carry one it never invokes. The mesh answers both with the copies it
# holds, because a fingerprint written here would name one particular copy and no other mesh has it
# (novox/hq issue 044). Declared in module.json's `build.on`; deliberately no defaults, so a build
# nobody told stops here and says which module to build first.
