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

Case
HOW- Goal
- verify pkg:golang/go.opentelemetry.io/otel/trace@v1.43.0
- Created
- 2026-08-19T21:47:30Z
Contract
- trace.ValidateSpanKind and trace.SpanKind.String validate span kind values and map them to their string names
- trace.NewSpanStartConfig and trace.NewSpanEndConfig construct span lifecycle configurations with timestamps, attributes, and kinds
- trace.NewEventConfig builds event configurations with timestamps, attributes, and stack trace flags
- trace.NewTracerConfig and trace.WithInstrumentationAttributes configure tracer metadata and attributes
- trace.SpanContext supports immutable updates via WithRemote, WithTraceID, WithSpanID, WithTraceFlags, and WithTraceState
- trace.ContextWithRemoteSpanContext injects remote span context into context.Context
- trace.TraceState.Walk iterates across all trace state entries in sequence
