The GPU probe shipped a moment ago did its job on the first live run: it
caught the cudnn failure and asked for a rebuild. The rebuild then stopped
with

    Parler requirements file missing: /opt/coderai/app/requirements-parler.txt

The container mounts `codai/`, `tools/` and `third_party/` over the image, so
a repo-ROOT file added since the running image was built is simply not there —
and a worker that heals itself must not stop for a reason that has nothing to
do with the venv. The same mistake was already on record as ACE-Step
reporting a missing `requirements-acestep.txt` for a venv that was fine.

The file stays the source of truth and wins whenever it is present; the same
pins also live in the worker for when it is not, with a test that parses the
file and compares, because two copies of a pin drift.
