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.

Case
HOW- Goal
- verify pkg:golang/go.opentelemetry.io/otel/trace@v1.43.0
- Created
- 2026-08-19T21:29:00Z
Contract
- trace.TraceIDFromHex and trace.SpanIDFromHex decode valid hexadecimal string representations
- trace.NewSpanContext creates a valid SpanContext with TraceID, SpanID, and TraceFlags
- trace.ParseTraceState and trace.TraceState manage W3C trace context key-value pairs with Get, Insert, and Delete
- trace.ContextWithSpanContext and trace.SpanContextFromContext store and propagate SpanContext across context.Context boundaries
- trace.LinkFromContext and trace.WithLinks attach span links to spans
- trace.NewNoopTracerProvider creates a tracer provider returning no-op spans
