Data Modeling — Producing the Stack-Native Schema

When to use

• OpenAPI spec passed Gate 4 validation (or Gate 4 SKIPPED for features with no API surface)
• System stores persistent data
• Large Track workflow (2+ day features)

Skip when

• Small Track workflow → skip to ring:writing-plans
• No persistent data → skip to Dependency Map
• OpenAPI spec not validated (and Gate 4 not SKIPPED) → complete Gate 4 first
