A diagram is only the beginning.

System-design studies built around constraints, decisions, failure modes, and operational reality. Selected deep dives are available to members.

Ingestion, retrieval, evaluation, observability, and the failure paths between them.

Durable execution, tool boundaries, memory, human approval, and recovery.

Routing, quotas, fallbacks, policy enforcement, caching, and cost attribution.
