What's Wrong?

When I run claude-code with a max number of turns, it sometimes ignores the max-turns and just runs for much longer.

What Should Happen?

Claude should respect the max_turns, not just ignore and blow past it.

Error Messages/Logs

See the attached log in the additional information section of the bug report, which shows us running very long, despite starting with max-turns being 100.

Steps to Reproduce

1. Create a task.md file containing some (hard) task.
2. Launch claude code in headless mode, with a max number of turns specified

claude -p "<entire TASK.md content>" \
  --max-turns 100 \
  --dangerously-skip-permissions \
  --output-format stream-json \
  --verbose \
  --model claude-sonnet-4-6

1. Watch it run for beyond 100 turns.

I cannot tell if this is because of compaction or something else – but compaction happened for us at turn ~67.
