What

Add a mandatory migration gate to req-dev covering existing-model reuse, real consumer tracing, stable API contracts, dual-write/projection, backfill, deduplication, rollback, and end-to-end user-visible acceptance.

Why

Prevent new write paths or ledgers from becoming disconnected from existing APIs and client-visible read models.
