Assurance is not a feature. It binds Governance, Evidence and Attribution into an institutionally admissible object that institutions can inspect, rely on, export and reconstruct without Terra Vita becoming the decision-maker.
The Hub closure path turns programme state into a verified, locked, admissible and reliance-ready object. Controlled sharing and the Institutional Ledger ensure that the assured object remains governed after export.
Each component has a bounded purpose, defined functions and non-discretionary outputs. Together they form the closure mechanism: Verification → Locking → Admissibility → Reliance, enforced through controlled sharing and recorded in the Institutional Ledger.
Validates that governance, evidence and attribution are complete, coherent and unbroken.
Freezes programme state at the moment of institutional closure.
Converts the locked state into an audit-ready object institutions can inspect.
Provides the institutional statement that the programme object can be relied on within its stated boundary.
Ensures the assured object is shared only within the correct authority boundaries.
Maintains a tamper-resistant, reconstructable history of all assurance events.
The Programme Evaluation Dossier is an output of the Assurance Layer between admissibility, reliance and committee-ready export. It is not a rating, score, certification, approval, audit opinion or substituted determination.
Minimum evidence met or unmet, gaps, redactions and lineage notes.
Roles, authority boundaries, reviewer routing and workflow integrity.
Methodology attachment, verification notes and scope alignment.
Completeness, coherence, lock integrity and admissibility criteria.
Bounded reliance statement, conditions, exceptions and reviewer accountability.
What can circulate, what remains protected and how the pathway is reconstructed.
Access, permissions and exports are enforced against role, programme, purpose and revocation rules. The assured object remains governed after circulation.
Every verification, locking, admissibility, reliance, access and export event is recorded as institutional memory for audit reconstruction.
The Assurance Layer now connects visibly to the committee export posture: verification report, locked programme state, admissibility certificate, reliance statement, assured sharing log and institutional ledger reconstruction pathway. The export pack remains a governed evidence route; it is not an approval or rating.
Structured export objects with scope, version, hash, reliance boundary, access permissions, unresolved gaps and reconstruction references.
Terra Vita does not approve, finance, regulate, rate or replace the statutory, fiduciary, MRV, audit or committee judgement of the institution.
FieldTrace supplies attributable field evidence, context and local attribution. The Hub receives signed, hash-bound envelopes and routes them into protected review intake before any institutional reliance posture is formed.
The Assurance Layer remains the closure architecture. The protected room turns it into identity-bound reviewer workflow: verification dossier, lock register, admissibility pack, reliance workspace, identity-bound sharing queue and institutional ledger reconstruction.
