Example of what I was thinking might be easier to golf (for some approaches):
Input 1:
```text
A
```
Input 2:
```text
A
B
```
Input 3:
```text
CC
CC
AB
```
Input 4:
```text
DDD
DDD
DDD
ACC
BCC
```
Input 5:
```text
EEEEE
EEEEE
EEEEE
EEEEE
EEEEE
BADDD
CCDDD
CC... (more) |

A question about the output rules that didn't occur to me in the sandbox:
> However, the output may be mirrored or rotated by multiples of $90^\circ$ as desired.
If I pick a particular rotation, do I need to use the same rotation for every input, or can I choose different rotations for differen... (more) |

In this particular case you may find `lines` instead of `split` saves you a few bytes. (more) |

In languages which are less restrictive about types than Rust, bytes can be saved by outputting a number instead of a string for a valid Roman number. For example, `return 1` instead of `return "G"`.
In languages which are even less restrictive, bytes can be saved by outputting something like `nul... (more) |

When the input is `CCCCC` the output should be `CCCC` (the relevant substring) but currently the output is `CCCCC` (the original input string). Looks like this may be due to a typo in the return statement.
Should
```rust
if s.contains(b){return s}
```
instead say
```rust
if s.contains(... (more) |

Great challenge. I particularly like the title.
The only other thing I can think to point out is the syntax highlighting on the code blocks. Currently the automatic highlighting is treating the code blocks as a language where `Input:` and `Output:` are coloured red. You might want to keep that as ... (more) |

Having had a think, it seems that 5 "colours" is necessary and sufficient for colouring the squares in order in a cycle (a, b, c, d, e, a, b, c, d, e, ...), and 4 colours is necessary and sufficient for colouring the squares if not restricted to cycling in order (a, b, c, b, c, a, d, a, b, c, b, c, ....

Is the output required to be in the same orientation as the example?
For example, would a mirror image or a rotation through a multiple of 90 degrees be valid?
I don't have a preference either way, but it might be worth explicitly stating which is the case. (more) |

Is it required that the range of characters end at either `z` or `9`? For example, if someone used `a` to `e`, and then wrapped back to `a`, would that be valid?
I don't have a preference either way, just mentioning a possibility.
(I suspect that a range of 5 characters is sufficient that no ad... (more) |

I like the examples. It would also be useful to have a few more test cases, including any edge cases. For example, what should the output be for input 0? (more) |

I understand that regex answers will be similar in most languages. The advantage of posting each language in a separate answer is that anyone wanting to compete in a particular language can easily see from the leaderboard what score they are competing against.

Even though it uses the same regex string, I recommend posting the spreadsheet formula as a separate answer. This way it will show up in the automated leaderboard for ease of comparison with other answers. (more) |

Some of what you mention may be covered by some of the [Meta posts tagged default-rules](https://codegolf.codidact.com/categories/48/tags/5434). Anything not covered could be added to one of those posts or perhaps added as a new post with that tag.

From the Output section:
> Your output is valid if rounding it to $6$ decimal places results in the output shown in the relevant test case.
Note that the competing code does not need to round the output, only to produce output that would match the test cases if it were rounded. So the Python co... (more) |

Interesting. I understand now.
Note that the code is no longer restricted to just that one version of Python - it works in the latest version (3.12) just fine. If you change the language in the heading back to just "Python" then the leaderboard will group this answer correctly with the other Pytho... (more) |

No need to apologise. I don't feel that I have any obligation to test answers, I just sometimes like to out of curiosity.

I know this isn't consistent with how semantic versioning is supposed to work, but it's my best current guess at why it doesn't work on my machine.
I suppose it's also possible there's an inconsistency between operating systems. I tested this on Linux (Fedora 39), on python 3.8.19, 3.9.19, 3.10.14... (more) |

It looks like there was a lot of discussion about whether to permit assignment expressions in comprehensions when they were first introduced in python 3.8. It may be that a change was made to python 3.9 after the version you are using. When I run the 222 byte version on python 3.9.19 I get an error m... (more) |

When the input is a valid Roman number, the output does not need to be specifically the string "VALID". From the first bullet point of the Output section, you just need to "output a consistent value" which "must not be one of the strings from the list of 50".
Hopefully this saves you some bytes. (more) |
