A practical field guide to turning model capability into a reliable product system.

The map

01 · System boundariesDefine users, responsibilities, trust boundaries, and failure domains.

02 · Model & runtimeChoose models, serving paths, fallbacks, and operating envelopes.

03 · OrchestrationDesign control flow, tool use, and human intervention.

04 · Data & stateHandle context, memory, persistence, and provenance deliberately.

05 · ReliabilityOperate for latency, cost, resilience, and observable quality.

06 · ReviewMake trade-offs and risks explicit before shipping.
