The supersteps-based delta history walk requires update_state to write counters_since_delta_snapshot metadata, but passing updated_channels to create_checkpoint also overrode checkpoint["updated_channels"] (was None), breaking deferred-node triggering on resume for non-delta graphs (test_in_one_fan_out_state_graph_defer_node). Keep updated_channels at its default so resume/trigger semantics are unchanged; still write the counter metadata and snapshot delta channels that hit their cadence.
