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.

HOW- Goal
- json.Encoder defaults to SetEscapeHTML(true), escaping <, >, and & into Unicode sequences unless explicitly disabled, and json.Marshal provides no option to disable this escaping.

Contract
- assert json.NewEncoder with default settings escapes <, >, and & into \u003c, \u003e, and \u0026
- assert json.Marshal unconditionally applies HTML escaping to <, >, and & with no option to disable it
- assert calling SetEscapeHTML(false) on json.Encoder produces literal <, >, and & in JSON strings
