API Contract Design — Producing the OpenAPI Spec

When to use

• TRD passed Gate 3 validation
• System exposes APIs (internal or external) that components or clients consume
• Large Track workflow (2+ day features)

Skip when

• Small Track workflow → skip to ring:writing-plans
• No API surface (batch job, library, internal worker) → skip to Data Model
• TRD not validated → complete Gate 3 first
