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
- In json >= 2.9.0, script_safe serialization avoids corrupting 3-byte CJK UTF-8 sequences into line/paragraph separator escapes while preserving U+2028/U+2029 escaping, and GeneratorError provides the invalid_object inspection attribute

Contract
- JSON.generate(..., script_safe: true) preserves 3-byte UTF-8 CJK characters without corrupting them into \u2028 or \u2029 escapes
- JSON.parse round-trips script_safe serialized CJK characters accurately
- JSON.generate(..., script_safe: true) continues to escape U+2028, U+2029, and </script> tags for safe inline HTML script inclusion
- JSON::GeneratorError#invalid_object returns the failing object on serialization errors
