real-subagent expectations (anonymized native sample, local ZCode 3.14.3)

This is native test data, extracted read-only locally on 2026-09-25 from the same run as real-main-session. anon numbers share that run’s stable mapping. Source: cli/rollout/model-io-sess_subagent_agent_<id>.jsonl, first four records of seven original lines. Version verification is the same 3.14.3 source as real-main-session.

Single-file expectations

  • Four events, identity zcode:{requestId}:1, call_category=sub_agent, session_id=sess_subagent_agent_anon-19, schema_version=“3.14.3”.
  • Primary AI SDK mapping: input_uncached=2569/3892/1395/1181 (derived), sum=9037.
  • Summary (UTC 2026-09-25): call_count=4, input_total_known=596,365, output_total_known=4,594, cache_read_known=587,328, cache_write_known=Some(0), total_tokens_known=600,959. Zero diagnostics.

Combined expectations (with real-main-session under one cli/rollout root)

  • call_count=8 (four primary, four sub_agent), input_total_known=2,163,849, output_total_known=5,768, cache_read_known=2,153,024, cache_write_known=Some(0), total_tokens_known=2,169,617, input_uncached sum=10,825 (=2,163,849−2,153,024−0).
  • Anthropic sums input_tokens=10,825, cache_read=2,153,024; cache_creation absent. These agree with exclusive AI SDK fields: 10,825+2,153,024=2,163,849. Select one representation; do not mix or add both.
