 ## How to Reproduce

-Run several agent sessions (or trigger gate failures that cause restarts). After enough sessions, zombie `[claude] <defunct>` processes accumulate. Check with `ps aux | grep '<defunct>'`. Once enough zombies exist, new agent spawns crash immediately with the fatal runtime error.
+Run several agent sessions. Check with `ps -eo stat,comm | grep Z | awk '{print $2}' | sort | uniq -c | sort -rn`.

 ## Actual Result

-`fatal runtime error: assertion failed: output.write(&bytes).is_ok(), aborting` — process exits instantly, session is None, burns retries. `ps aux` shows many `[claude] <defunct>` zombie processes.
+Zombie processes accumulate continuously. Never reaped.

 ## Expected Result

-All child processes should be properly reaped after exit. No zombie accumulation. New agent spawns should always succeed regardless of how many previous sessions have run.
+No zombie accumulation during normal operation.

 ## Acceptance Criteria

 - [ ] Zombie processes do not accumulate during normal operation (including grandchildren from npm/cargo)
 - [ ] `child.wait()` is called after `child.kill()` in all code paths in `claude_code.rs`
- [ ] Agent restart after gate failure does not crash the PTY
 - [ ] Verified with `ps aux | grep '<defunct>'` after running multiple agent sessions
