Report #84379

[architecture] Undiagnosed failure propagation due to lack of distributed tracing across agent boundaries

Implement OpenTelemetry with LLM semantic conventions \(gen\_ai span attributes for token counts, model IDs, prompt templates\) and deterministic checkpoint versioning; propagate trace context \(traceparent headers\) through message queues and RPC between agents.

Journey Context:
Standard logs create 'blind spots' when Agent A calls Agent B via async message bus; correlating logs requires distributed tracing. LLM-specific conventions capture token usage and latency per agent, not just wall-clock time. Deterministic replay requires checkpointing state \(inputs, random seeds\) at each agent boundary. Tradeoff: tracing adds overhead \(spans per token generation\); requires centralized collector \(Jaeger/Zipkin\).
