Platform Layer

Evaluation, Observability & Reliability

Teach how AI systems are measured, debugged and operated safely in production.

Why This Matters

You cannot ship a probabilistic system on logs meant for request/response APIs. Evals, traces, and SLOs are how architecture becomes operable.

Architecture Position

Platform Layer: gateways, observability, evals, and infrastructure sit beside every runtime hop. See it on the architecture map.
