Sprint 107 Plan: Safety-Critical Deployment Profiles

Context

Some environments demand stricter deployment profiles than general stable tiers. Sprint 107 introduces safety-critical deployment profiles and evidence requirements.

---

Goals

1. Define safety-critical deployment profiles with stricter gates
2. Require enhanced evidence and reviewer quorum for promotion
3. Add traceable hazard/risk linkage to migration decisions
4. Support safe downgrade pathways when profiles cannot be met

Safety Rule

• Safety-critical promotions require quorum and complete profile evidence.
