Observability isn't a dashboard or log aggregator; it's an architectural discipline. This module teaches you to build the Observability Stack: a four-layer architecture that turns cognition in motion into evidence in motion. From instrumentation at the source to response loops that drive correction, you'll implement the complete 5-phase field framework proven in enterprise deployments.

You'll work with production-ready code templates for event schemas, emitter SDKs, privacy masking, and secure collection pipelines. Through hands-on labs, you'll instrument reasoning loops, implement policy-bound telemetry, and build replay capabilities that make decisions reproducible under identical conditions. The module culminates in implementing a complete trace → drift → trust loop for your own agentic components.
