Complete

Step durations aren't available on this connection, so per-step and total timings are omitted rather than shown as a misleading 0ms. The lifecycle stages above did occur (the Canton↔EVM correlation is confirmed); only the sub-step wall-clock timing is unavailable — it requires a data source that reports distinct step timestamps rather than an atomic commit.
