[architecture] Undebuggable failures in multi-agent chains where causality is lost across asynchronous handoffs

Propagate W3C Trace Context headers \(traceparent/tracestate\) through all agent-to-agent messages, storing span context in distributed tracing backends \(OpenTelemetry/Jaeger\) with explicit event logs for contract validation points and confidence scores

Journey Context:
Without distributed tracing, debugging a 5-agent pipeline is guesswork. Each agent must emit telemetry with shared trace IDs. W3C Trace Context is the standard for this. The 'baggage' feature can carry workflow context, but don't put PII there. This enables latency analysis \(which agent is the bottleneck\) and bottleneck detection in agent chains. Explicit annotations when contracts fail validation or confidence thresholds trigger help correlate business logic errors with infrastructure telemetry.
