// The audit-logger's entrypoint. The per-node module runtime imports this once the broker is
// bound; the on("#") subscription is the whole handshake — it consumes every event on the mesh
// (module.*, mesh.*, node.*) and writes each to the trail.
//
// **No event is lost** (novox/hq issue 276). A line that cannot be written is thrown, so the bus offers
// the event again; the first failure spools it on disk, its last delivery is taken from the spool, and
// the spool is replayed into the trail once writing works again (spool.ts). The trail skips an event id
// it already holds, so a redelivery or a replay never writes it twice (audit.ts).
