Terra Vita Hub — Reviewer Compression Layer (v255)

1. Terra Vita Hub is enterprise assurance infrastructure for governance and MRV workflows.
2. It sits between institutional evidence and human authorisation.
3. It is not a financial service, rating activity, statutory authority, investment adviser, client-asset custodian or MRV methodology.
4. Institutions retain approvals, fiduciary judgement, policy authority and public accountability.
5. Evidence remains attributable to source, programme context, reviewer action and export state.
6. MRV methodologies remain external authority objects and are attached to evidence, not substituted.
7. Reviewer actions are identity-bound, role-scoped, purpose-bound and auditable.
8. Overrides require authorised roles, recorded rationale, evidence basis and risk context.
9. Access is revocable, role-scoped and time-bounded where required.
10. Public pages show posture, route, templates and redacted proof objects only.
11. Protected diligence contains deployment-specific evidence, controls, exports and audit detail.
12. Tenancy can be single-tenant by default or logically separated multi-tenant when approved.
13. Export packs are versioned, controlled and reconstructible for committee review.
14. The only canonical route is: Brief -> Review Index -> Evidence Request -> Protected Diligence.
