What

The typed config declarations are collected into a single object rather than scattered namespaces, giving uniform parsing of environment values. Integer entries can now declare minimum, maximum and digits-only constraints, and some entries carry explicit value lists, such as a policy that must be enforce, observe or off.

Evidence

C.enum(["enforce", "observe", "off"])

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
