This fork of dry-validation is based of v0.13 but works under a different namespace LegacyDry to avoid conflicts with the original gem. It doesn't depend on any other dry-rb gems, except for dry-configurable v0.13+, which is a very small dependency.
This will allow you to use both the latest version of dry-validation and this legacy version in the same project. Then you can migrate your codebase to the latest version of dry-validation at your own pace.
