`Packet.fields_desc` is currently hinted with `# type: List[AnyField]`, which results in a tooling conflict with [RUFF012](https://docs.astral.sh/ruff/rules/mutable-class-default/). Suggestion - import `typing.ClassVar` and apply the type hint to `fields_desc` like so: `# type: ClassVar[List[AnyField]]`
