I am currently completing and reviewing this pull request.

Maybe @marstamm can have a look since I did quite some work on this and don't want to merge it without double-checking.

Will have a look

[q] how does the secret rule work for inputs? In the test case in camunda-compat, it is marked as valid with source="{{}}". However, we enforce FEEL expressions for inputs, so ={{secrets.FOO}} causes a syntax error. Is ="{{secrets.FOO}}" the correct way then?

Yes, from a user's perspective only ="{{secrets.foo}}" would work. For the sake of the test case which only uses the secrets rule FEEL isn't relevant.

Makes sense, thanks you!

Looks good to merge to me after we adjust the error messages
