TRD Creation — Architecture Before Implementation

When to use

• PRD passed Gate 1
• Feature Map passed Gate 2 (Large Track only)
• About to design technical architecture

Skip when

• PRD not validated → complete Gate 1 first
• Architecture already documented → proceed to API Design (Large) or plan (Small)
• Pure business requirement change → update PRD

Sequence

Runs before: ring:designing-api-contracts (Large Track) / ring:writing-plans (Small Track) Runs after: ring:mapping-feature-relationships (Large Track) / ring:writing-prds (Small Track)
