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 JSON.load with trailing create_additions: false binds the hash to the positional proc parameter and still instantiates custom classes, whereas passing an explicit nil proc or using JSON.parse safely returns a Hash
- assert JSON.parse rejects nesting depth exceeding 100 with JSON::NestingError, but max_nesting: 0, false, and nil all disable depth enforcement completely rather than forbidding nesting
- assert JSON.parse with freeze: true deeply freezes all containers, nested arrays, strings, and symbolized keys, raising FrozenError on in-place mutation at any depth
- assert JSON.generate leaves </script> unescaped by default, while script_safe: true escapes </ to <\/ without altering round-trip parsed data and ascii_only: true encodes non-ASCII into unicode escapes
- assert custom container classes passed via object_class receive Symbol keys directly when symbolize_names: true is enabled
