+## Verification (2025-06-25)
+Implementation verified complete. All cleanup mechanisms are in place:
+- ✓ `cleanup_orphans()` called at startup in `main()`
+- ✓ `CleanupGuard` ensures cleanup on all exit paths via Drop
+- ✓ `cleanup_temp_dir()` handles cleanup before `process::exit()`
+- ✓ `exit_with_cleanup()` wrapper used throughout `main()`
+
+All exit paths covered: normal exit, errors, watchdog timeout, signal interruption.
