Field systems architecture.
Designs country-site workstreams, partner routes and field artefact pathways across agriculture, mining, coastal and resilience contexts.
Global field systems, FieldTrace evidence and Terra Vita Hub review intake.
This page explains the public institutional relationship between Terra Vita Global, the FieldTrace field evidence app and Terra Vita Hub. It is a route map only: operational consoles, evidence files, operator records and review decisions remain protected.
Three surfaces, one governed evidence pathway.
Operator-attributed capture.
Captures visit and task events from named operators, producing signed and hash-bound event envelopes for Hub receiver intake.
Protected review intake.
Verifies receiver signatures and manifests, records ingest events and opens protected review-intake rows for institutional review.
The receiver creates review intake, not institutional judgement.
Posture and route metadata.
Public pages describe the relationship between Global, FieldTrace and Hub receiver intake without exposing protected programme records.
Evidence, operators and review records.
Field evidence, signed envelopes, operator identity, receiver ingest rows and review-intake decisions remain behind protected access controls.
Institutions retain authority.
Terra Vita does not rate, certify, approve, finance or replace institutional judgement. The route structures evidence for review only.
The Hub receiver accepts signed, hash-bound FieldTrace envelopes.
| Stage | Function | Institutional value |
|---|---|---|
| FieldTrace outbox | Stages event records with route keys and manifest hashes. | Prevents silent movement of field evidence into review surfaces. |
| Hub receiver | Verifies HMAC signature and manifest hash before ingest. | Creates a tamper-evident acceptance boundary. |
| Review intake | Creates protected Hub-side intake rows. | Allows reviewers to inspect received records without turning receiver intake into approval. |
| Acknowledgement | Returns deterministic Hub acknowledgement IDs to FieldTrace. | Closes the event loop for audit reconstruction. |
