[WARNING] cache problem : 20200105/WXO-DD/meteocode/atl

likely spurious warning message... running a static flow test I see it popping up:

```

```

It looks like it is complaining about a directory path not being covered by any accept/reject patterns... defaults to accept, and gets published... so I think it is harmless... but the error message is ... distracting? investigation needed.

Start by reproducing the static flow test described in the report and trace where the cache warning is emitted for the 20200105/WXO-DD/meteocode/atl path. Determine whether the path should trigger that warning despite default acceptance; done means the warning behavior is corrected or its harmless nature is made explicit, with a regression check if the project has one.
