Raw Normal View History

Rework secondary check flow Checks.cs initially started out small, but over the years it has grown to handle multiple types of checks. With all these checks next to eachother, it's hard to see the overall groups. Splitting them up (potentially further?) allows for more focused maintenance & understanding. Not sure if I'm happy with the overall bandaids used (checks no longer done within LegalityAnalysis so variable repointing is excessively used), but I'm happier the way it is now compared to the huge Checks.cs
