How to instrument multi-agent systems with OpenTelemetry, propagate trace context across an in-memory bus, and build a layered evaluation pipeline — from real-time policy gates to async LLM-as-judge to SLO-based trust scoring. Everything I learned building Genie.
Notes from integrating OpenTelemetry into airshipit, an open-source bare-metal Kubernetes lifecycle project with contributions from Ericsson, AT&T, Microsoft, and others. The hard part wasn't OTel; it was making distributed traces useful across foreign code.
