- Local experiment on MacBook Air M1, 16 GB, macOS 26.5.1, Flutter 3.44.7 / Dart 3.12.2, on battery. The table covers Flutter profile, with 50 requests per strategy and size. No Android/iOS/Web, memory, energy, input latency, user preference, cancellation or request-race measurements. Copying cost was not isolated. Two hidden-window attempts were excluded in full and preserved. Publication preparation did not rerun the experiment.
