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. trace.TracerProvider.Tracer configures tracer instances with WithInstrumentationVersion and WithSchemaURL options
  2. trace.SpanFromContext and trace.ContextWithSpan inject and extract active trace.Span instances into context.Context
  3. span.RecordError records errors on active spans with optional stack trace and timestamp configuration
  4. span.SetStatus sets span status codes and status descriptions using codes.Code constants
  5. span.SetName updates the operation name dynamically on an existing span
  6. trace.WithNewRoot creates a root span that ignores any existing span in the parent context
  7. trace.TraceFlags.WithSampled and trace.TraceFlags.IsSampled manipulate and inspect sampling bit flags
