Exemplo

SpanFromContext never returns nil on untraced contexts but yields invalid non-recording spans whose IDs format to 32-character and 16-character zero strings rather than empty strings, RecordError does not set error status, and NewSpanContext drops all fields if either TraceID or SpanID is zero

Contrato

• assert SpanFromContext returns non-nil noopSpan with IsRecording false and invalid SpanContext on untraced context
• assert invalid TraceID and SpanID format to fixed-length zero strings instead of empty strings
• assert ContextWithSpan with nil does not clear span and still returns non-nil noopSpan
• assert RecordError creates exception event but leaves span status code Unset without explicit SetStatus
• assert TraceIDFromHex and SpanIDFromHex return errors on all-zero hex strings
• assert NewSpanContext returns invalid empty SpanContext when either TraceID or SpanID is missing or zero
• assert ContextWithRemoteSpanContext forces IsRemote true on non-recording span context
• assert Tracer.Start inherits parent TraceID by default but generates fresh TraceID when WithNewRoot is specified
