As for editing the `undefined` score answer, I haven't made any edit myself because it's not just a different format - the answer is labelled as "not a golfing answer". I don't know whether higher Meta traffic in future might bring a consensus on whether non-competing answers are to be allowed, and w... (more) |

Thanks for spotting the new evidence - hopefully that helps someone understand the underlying cause(s).
I think that this is rare, as most challenges do not have invalid format answers. However, there may be a problem even when all answers are formatted correctly:
I tried ticking and unticking ... (more) |

[An upvoted answer on the defaults for I/O Meta post](https://codegolf.codidact.com/posts/282784/282842#answer-282842) suggests general truthy and falsy outputs can be used where the challenge does not explicitly require exactly 2 distinct values. You could suggest a more general default that allows ... (more) |

When the community grows and there is more conclusive voting, I would like to see those rules that have reached consensus moved to a help page. I agree it's not definitive at present.

The Meta post is deliberately in the form of a list of proposals, so that voting can indicate which ones have community approval. If there are plenty of upvotes and no downvotes I take that as a default rule. If there are very few upvotes, or a mix of up and downvotes then I'm more likely to make a c... (more) |

I agree that it is arbitrary. The only difference is simply that input as function arguments has support in the form of upvotes, whereas input as a pre-existing variable has support for only being allowed when there is no other alternative.
I don't have a strong opinion on what the rules should be... (more) |

So the general answer is "yes you can use a library but it will be classed as a different language", but for this challenge specifically I'm not expecting a graphics library to be necessary, or even particularly advantageous. I'm aiming for a graphics challenge that is so reduced that the code can be... (more) |

Consensus on Meta seems to be that an answer in a language can include the standard library, although the bytes needed for importing it (if any) count towards the score. For other libraries, using them would count as competing in a different language. See [Default Rules: Libraries](https://codegolf.... (more) |

I'm happy to accept the defaults on Meta: [Default Rules: Code Golf I/O](https://codegolf.codidact.com/posts/282784).
This means taking input as command line arguments, or from STDIN, or as function arguments are all acceptable approaches. I didn't see reading from a text file mentioned there but ... (more) |
