- classify a carrier throw under a caller-aborted signal as gateway/cancelled instead of gateway/internal, matching the code the Host produces when the abort wins the wire round-trip. - read $host facts from the construction-time Connection handle, matching $stream; the service cannot be replaced without restarting this plugin, so the live re-lookup was dead complexity. - state rebuiltFailure's actual contract in its comment: codes pass through verbatim without runtime validation. - correct the @module name in dsh-util-time.
