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
- sign HS256 with SignJWT and verify with jwtVerify, asserting it resolves to {payload, protectedHeader} rather than to the claims
- assert an HMAC key must be bytes: a plain string secret fails with a TypeError that is not a JOSEError and carries no .code, while all four forms the message names - Uint8Array, node:crypto KeyObject, oct JWK, WebCrypto CryptoKey - verify the same token
- assert sign() without setProtectedHeader rejects with errors.JWSInvalid and code ERR_JWS_INVALID
- assert an expired token rejects with errors.JWTExpired, code ERR_JWT_EXPIRED, claim exp, reason check_failed and the decoded payload attached, and that clockTolerance lets the same token through
- assert JWTExpired is a sibling of JWTClaimValidationFailed and not a subclass, so catching claim-validation failures misses expiry
- assert nbf is checked without being asked and fails as a plain JWTClaimValidationFailed with claim nbf, on the other side of that split from expiry
- assert a wrong key and a tampered payload both reject with errors.JWSSignatureVerificationFailed and code ERR_JWS_SIGNATURE_VERIFICATION_FAILED, while decodeJwt still reports the forged claims
- assert issuer and audience are validated only when passed as options, failing with ERR_JWT_CLAIM_VALIDATION_FAILED and reason check_failed for a mismatch and reason missing for an absent claim
- assert a token minted with no exp verifies forever unless requiredClaims names exp
- assert alg is taken from the token header unless algorithms is pinned: a real HS512 token verifies unpinned but is refused with ERR_JOSE_ALG_NOT_ALLOWED when pinned
- assert an UnsecuredJWT alg:none token is refused by jwtVerify even unpinned, with ERR_JOSE_NOT_SUPPORTED, and that an RS256 header with a symmetric key is refused by the alg check when pinned and by a TypeError when not
- assert jose does not enforce the RFC 7518 minimum HMAC key size: a five-byte HS256 key signs and verifies, and WebCrypto underneath imports the same 40-bit HMAC key without complaint
- assert jwtVerify never throws synchronously, so an unawaited call yields a truthy Promise and its failure reaches process.unhandledRejection, and measure in a child process that the same orphaned rejection exits node with status 1
- assert jose ships no CJS export condition and no default export, that importing a default binding from it fails at link time with a SyntaxError, and measure that require('jose') nonetheless succeeds on Node 22
