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.

Contract
- assert script_safe escapes HTML script tags and JS line terminators without corrupting 3-byte CJK characters sharing trailing bytes with U+2028 and U+2029
- assert JSON.parse supports JavaScript comments by default but rejects trailing commas unless allow_trailing_comma is enabled
- assert JSON.pretty_generate formats empty arrays and objects compactly on a single line without inner newlines
- assert JSON::GeneratorError captures the exact offending instance in invalid_object when strict generation fails on nested objects or symbols
- assert default generate silently coerces unknown objects and symbols via to_s unless strict mode is enabled
