# One machine that becomes a mesh and then assigns itself mosquitto — the bed that proves the
# run-once primitive (novox/hq ADR 0052) end to end.
#
# mosquitto is the sharp case ADR 0052 was written for: its Dynamic Security plugin loads at broker
# start and refuses to come up unless `dynamic-security.json` already holds an admin client. That
# file is not state a reconcile loop can carry — it is a step that must run once, after the data
# directory exists and BEFORE the broker container starts. mosquitto's manifest declares that step
# as a `run-once: true` init container, placed before the `server` (broker) container: the same
# runtime image, carrying mosquitto's own `bootstrap/` entrypoint and `mosquitto_ctrl`, run to
# completion under the module's own account. The host runs it, requires exit 0, and only then reaches
# the broker — so "the broker came up" is itself the proof the seed ran, because an unseeded store
# crash-loops the broker.

#   scripts/build-module-runtime.sh mosquitto builds mesh-runtime-mosquitto:development (carrying
#   mosquitto_ctrl and the compiled bootstrap entrypoint) into the local daemon, which this scenario
#   stocks and serves by digest from its own registry. eclipse-mosquitto:2 must be in the local
#   daemon to be stocked.
