# lavinmq's runtime: the tool runtime, carrying this module's compiled bootstrap, 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.
#
# 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.

# writes the broker's configuration before it first starts, a provisioner that grants consumers
# their own vhost and user, a set of tools, and an event consumer.

# What the runtime loads from this module in serve mode: its event consumer, its tools, and its
# provisioner — all three in one process, so the provisioner's reconcile loop runs with the broker
# connected (novox/hq issues 060/061; the provisioner used to be run as a separate container `args`
# command, which meant it served no tools and, once, ran nowhere at all). The run-once bootstrap is
# NOT listed here — it is named in its own container's `args`, because it runs to completion before
# the broker starts rather than serving. One image, because they are one module and share a client.
