CLASS_CHECKED
What happened
A strategy handed over as a class, in a notebook or a test, is checked as a class. The checks that read the file itself, such as the position of FORGE_API and the lint rules, run when the file is saved.
What to do
Nothing, while you are trying things out. Save the file and check it before you rely on the result.
Example
text
strategy.py, line 1: Loaded from a class: the file-level checks run when the file is saved. [CLASS_CHECKED]The wording of the message depends on your file, and the code does not. A warning does not stop the file from loading.
