Probing problems with repo-review checks on tests + docs folders

[pp-mo]

Aiming to crudely break both the "has a tests folder" and "has a docs folder" checks for sp-repo-review.
(expected both PY004 and PY005 to fail)
Spoiler : oddly, this doesn't seem to trigger either error as expected
- there is no reported error in the pre-commit.ci run ???

Now removed the entire (renamed) docs folder, but the pre-commit.ci still passes, including the repo-review check.
And checking "pp-mo/iris_grib" branch "develop" via their Pyodide-based web interface, likewise also passes + reports "Has a docs folder".
( "develop" branch being same as this, but apparently required as the web-based check only accepts certain branch names )
Total mystery at this point
