Provider 25% Advancement Authorization + Bounded Step Execution Foundation
This gate prevents a clean 15% outcome from silently becoming 25% traffic. QA can rehearse the exact 15% → 25% advancement only. Production authorization, accepted live requests, network dispatch, and any jump toward 50% remain disabled.
