# Propagate Sender — provider role of cp:padi.test.propagate.
# Property names carry their PURPOSE; the registry's server/propagate flags
# carry direction and reach. bulletin is posted to everyone; draft never
# leaves this node; ping is echoed back by receivers.
# NOTE: invalid until padi.test.propagate is registered at cp.padi.io (by design).

title: Propagate Sender
description: Provider side of the propagate test rig - posts a bulletin (propagated), keeps a draft (not propagated), pings receivers, and shows what comes back (and what cannot).

behavior:
  init:
    bulletin: hello everyone
    ping: "0"
    # NB: draft deliberately NOT initialized — a non-propagated value existing
    # at bind time prevents the broker from ever binding (empirical finding,
    # 2026-07-19). Write it from the faceplate after binding.
