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
- Compare embedded structs containing unexported fields using cmpopts.IgnoreUnexported without runtime panics
- Packages
- Symbols
-
- cmp.Diff
- cmp.Equal
- cmpopts.IgnoreUnexported
- cmpopts.IgnoreFields
- Environment
- go
- Created
- 2026-08-16T12:11:34Z
Contract
- assert cmpopts.IgnoreUnexported on an outer struct panics when comparing embedded structs with unexported fields
- assert cmpopts.IgnoreFields panics when given a promoted field name from an embedded struct
- assert cmpopts.IgnoreUnexported succeeds when every embedded struct type is explicitly passed alongside the outer struct
- assert cmp.Diff detects differences in public fields of embedded structs when unexported fields are ignored
