Sprint 69 Plan: Multi-Team Policy Federation and Tenant Isolation

Context

Different teams require different risk tolerances and policies. Sprint 69 adds federated policy support with strict tenant isolation.

---

Goals

1. Support organization/team-scoped transpilation policies
2. Isolate metrics, decisions, and waivers by tenant
3. Allow shared adapters with tenant-specific gate policies
4. Preserve reproducibility under federated configurations

Isolation Rule

• Tenant data/artifacts must never leak across policy scopes.
