Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert err serializes Error into type, message, stack and custom properties while providing a non-enumerable raw reference
  2. assert errWithCause recursively serializes nested cause Error objects instead of concatenating to the message
  3. assert req serializes HTTP request metadata including method, url, headers, and socket remoteAddress and remotePort
  4. assert res serializes HTTP response statusCode when headersSent is true and retrieves headers via getHeaders
  5. assert wrapErrorSerializer, wrapRequestSerializer, and wrapResponseSerializer wrap custom serialization logic around standard serializers
  6. assert mapHttpRequest and mapHttpResponse wrap serialized request and response objects under req and res keys
