FORGE_API_RETIRED
What happened
The level the file declares is past its retirement date. A version saved before that date still opens and still runs, so old results stay reproducible. A new version has to use a current level.
What to do
Change FORGE_API to the level the message names when you next edit the file, and fix what the checks then report.
Example
text
strategy.py, line 1: FORGE_API 1 was retired on 2027-06-30. Saved versions still open and run, but a new version must use FORGE_API 2. [FORGE_API_RETIRED]The wording of the message depends on your file, and the code does not. A warning does not stop the file from loading.
