step.end repeats usage.record and does not count separately. Session-scope compaction counts independently as auxiliary. micro_compaction.apply is a control record with no event. Expected: two events, primary {100,50,400,0} and auxiliary {900,70,0,0}; input_uncached=1000, cache_read=400, output_total=120, input_total=1400, total_tokens=1520.
