Compatibility is pattern+vendor intersection with the destination's audience_activation.methods; receiver fields (destination_ref, consumer_identities, bind_expiry_days) are resolved from the destination at activation time. tmp_identity_match is excluded because no membership file moves. Experimental (signals.delivery_methods); see docs/reference/experimental-status.",
