[plan] Remove draft state and scrub sensitive information

_Automatically composed from the parent epic at dispatch time._

Split by the architecture's boundaries: 15 coder children across 8 phases. Mirror engine, then check and connectors, then scrubs, then the rename waves R1–R6 in parallel, then v1 retirement, then publish and wipe. Each wave adds at most one migration. Every rename wave needs the dev and prod census before it merges. Acceptance tightened for the ref sweep and the brand sweep. Memory: none applied.
