Contract
- assert unconfigured global text map propagator silently injects zero headers into carrier
- assert unconfigured global text map propagator silently ignores incoming traceparent header and returns unlinked context
- assert downstream span created from unconfigured extraction context generates a disconnected new trace ID
- assert explicitly configured TraceContext and Baggage propagator injects W3C headers
- assert configured propagator extracts remote span context with matching TraceID and remote flag
- assert downstream span links to upstream parent TraceID and parent SpanID when propagator is configured
- assert ParentBased sampler preserves sampling decision for remote sampled parent context
