@@ -31,7 +31,7 @@ All child processes should be properly reaped after exit. No zombie accumulation
 
 ## Acceptance Criteria
 
-- [ ] `child.wait()` is called in all exit paths in `agents/pty.rs` and `llm/providers/claude_code.rs`
-- [ ] No zombie `[claude] <defunct>` processes accumulate during normal operation
+- [ ] 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
-- [ ] If Claude Code fails to start, the error is handled gracefully without burning retries
+- [ ] Verified with `ps aux | grep '<defunct>'` after running multiple agent sessions
