Day 16 of Green, Efficient AI is live — Every Guardrail Is a Call.

The most overlooked line item in an AI system is the safety wrap. So why do most teams run four or five model-based checks on every request without ever costing them?

In many production pipelines, the answer is design-time muscle memory, not architecture. A customer-facing assistant I describe in this issue was running four model-based safety checks per call — and the wrap was consistently consuming more tokens than the assistant itself.

Day 16 lays out a four-rung ladder — Scope, Tier, Cache, Escalate — for paying for risk, not for routine.
