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.SpanFromContext and trace.ContextWithSpan inject and retrieve active spans in context.Context
  2. trace.ContextWithSpanContext and trace.SpanContextFromContext inject and retrieve SpanContext directly into context.Context
  3. trace.LinkFromContext creates span links extracting SpanContext and custom attributes from parent contexts
  4. trace.Span.AddLink dynamically attaches Link instances containing valid SpanContext and attributes to active spans
  5. trace.Span.IsRecording and trace.Span.TracerProvider report span recording state and access parent tracer provider
  6. trace.SpanContext.WithRemote, WithTraceID, WithSpanID, WithTraceFlags, and WithTraceState create immutable updated copies
  7. trace.ValidateSpanKind validates standard SpanKind constants and coerces invalid values to SpanKindInternal
