Governance Spine → Institutional Review Surfaces → Stewardship Benchmarking.
Governance Architecture
The architecture is organised around the seven-layer Governance Spine: identity, evidence, routing, assurance, MRV attachment, export and audit reconstruction.

Stewardship Benchmarking (Governance Spine Placement)
Institutional Surface — Governance Spine Layer. Stewardship Benchmarking is a governed Hub module that reconstructs capital behaviour on land using attributable evidence from FieldTrace, land records, ownership records and transaction histories. It enables institutions to review land-use, capital and ecological behaviour through a canonical reviewer route, without issuing ratings, certifications or investment advice. All outputs are reviewer-grade, evidence-bound and aligned with the governance spine. This module provides the transparency required for land-use oversight, generational transition, and capital-behaviour accountability.
Reviewer route
Evidence Intake → Attribution → Behaviour Reconstruction → Reviewer Assessment → Benchmark Output.
Authority boundary
No regulatory substitution, ratings, certification, ESG scoring or investment advice.
Architecture now sits before assurance and evidence request.
Reviewers can move from orientation into the Governance Spine, then into the Assurance Layer and FieldTrace evidence route before requesting protected diligence.

Public orientationArchitecture + assurance reviewProtected diligence
FieldTrace → Hub Integration — signed field evidence envelopes into assurance.
FieldTrace envelopes enter Terra Vita Hub through a signed, hash-bound receiver. The receiver verifies the manifest and HMAC signature, records the ingest event, opens a protected review-intake row, and returns a deterministic Hub acknowledgement ID.
Public posture
Reviewer-facing architecture only: receiver posture, authority boundary, event-envelope route and search metadata.
Protected intake
Operator records, evidence files, review-intake rows and intake decisions remain in protected Hub workspaces.
Authority retained
FieldTrace receiver intake is non-binding until an institution, committee or authorised reviewer acts under its own authority.

Assurance Layer — verification, locking, admissibility and reliance.
The Assurance Layer binds Governance, Evidence and Attribution into an institutionally admissible object. Controlled sharing and the Institutional Ledger preserve the reliance boundary after export.
Verification
Completeness, coherence, authority and attribution checks before reliance.
Integrity Lock
Freeze, hash and snapshot the programme state at institutional closure.
Reliance
Generate the institutional reliance statement without replacing judgement.
