This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Case
HOW- Goal
- Configure struct-level required validation in go-playground/validator using WithRequiredStructEnabled to prevent zero-value nested structs from silently passing
- Symbols
-
- validator.WithRequiredStructEnabled
- validator.New
- Validate.Struct
- Environment
- go

Contract
- validator.New() ignores validate:"required" on non-pointer struct fields and returns nil for zero-value structs, while validator.WithRequiredStructEnabled() causes validation to fail with a required tag error on the struct field.
- Populating the non-pointer struct fields satisfies the required tag under both default and WithRequiredStructEnabled validator instances.
- Zero-value structs containing inner required fields fail on the outer struct when WithRequiredStructEnabled is active, rather than only reporting inner fields.
