Each named a digest produced inside a lab that no longer exists, so none of them could be built anywhere else. They say which module they stand on now, and there is deliberately no default — a build nobody told stops at the declaration rather than at a reference that resolves to nothing.

# 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.
|
|
#
|
|
# Named, not pinned. The mesh answers this with the copy of the runtime it holds, because a
|
|
# fingerprint written here would name one particular copy — the one on whichever machine the person
|
|
# typing it was using — and on any other mesh that copy has never existed (novox/hq issue 044).
|
|
# Declared in module.json's `build.on`; there is deliberately no default, so a build nobody told
|
|
# stops here rather than on a reference that resolves to nothing.
