Esta rede oferece uma coisa: uma amostra que compila. Ela a executou em um sandbox e guardou o recibo assinado. Não classifica nem garante nada — se o mesmo código compila onde você está, ela não mediu.
Quantas chaves de assinatura distintas enviaram um recibo de contrato aprovado. Uma é só o autor; mais de uma significa que outra pessoa também o compilou. Uma chave é gerada por conta própria e não tem identidade registrada por trás, então conta chaves, não pessoas.

Contrato
- assert JSON.parse hands back String keys at every depth while symbolize_names: true changes keys only and leaves String values alone
- assert generate accepts symbol keys, so a Hash keyed by symbols round trips into string keys and stops equalling itself
- assert a non-String key is stringified by generate, symbolize_names then yields :"1" rather than 1, and two keys that stringify alike are both written and then collapsed by the parser, last one winning
- assert JSON.generate and to_json emit the same bytes for an object whose to_json accepts the state
- assert what to_json receives is a JSON::State that only a direct call omits, and that an object which accepts the state and drops it comes out compact inside a pretty document that still parses equal
- assert an arity-zero to_json works only on a direct call and raises ArgumentError through JSON.generate or from inside any container, including via Hash#to_json
- assert the generator splices in whatever to_json returned without checking it, so an invalid fragment builds a document JSON.parse rejects
- assert an object with no to_json is emitted as its to_s in quotes, symbols included, and only strict: true turns that back into a JSON::GeneratorError
- assert JSON.generate refuses NaN and Infinity, to_json refuses them identically, allow_nan writes them, and JSON.parse rejects that output unless it is given allow_nan too
- assert JSON::GeneratorError and JSON::ParserError are both JSON::JSONError, so one rescue covers both directions
- assert JSON.dump defaults to allow_nan and writes a document JSON.parse cannot read while JSON.load can, and that JSON.load defaults to allow_blank so an empty string is nil where JSON.parse raises
- assert a 2**53+1 integer and a thirty digit integer survive a round trip exactly, while the same digits with a decimal point lose the low bit and regenerate in exponent form
- assert bigdecimal is not visible under bundler at all, and that decimal_class: String keeps every digit of a fraction while leaving integers as Integer
- assert JSON.pretty_generate parses equal to the compact output, preserves key order in both, keeps empty containers on one line and writes no trailing newline
- assert json is absent from the bundle yet answers as a default gem at the version the purl names, and that the parser and generator actually loaded are .so files under the interpreter's own archdir
- assert no compiler and no make are on PATH and that requiring oj is a LoadError
