What the Record Engine does
The Record Engine is the horizontal layer underneath every product GeoClear ships. For eligible GeoClear verdict responses:
- Records the relevant operational inputs, binds them to policy context, and issues an operational evidence record through the GeoClear trust boundary.
- Persists the operational evidence record append-only on the GeoClear side; emits it on the response header so the customer also holds it.
- Cross-references a public Key Transparency surface so any verifier can audit which key issued at which time.
- Cross-references the unified trust manifest so every channel a verifier needs is discoverable from one URL.
The issuance substrate is decision-domain-agnostic: the same trust boundary issues operational evidence records for an address verification, a flood determination, a credit decision, or an autonomous-routing verdict. The Record Engine doesn’t care what the decision is, it cares that the decision is bound to a tamper-evident operational evidence record the customer can verify later.
Reference Implementations
Each Tier 2 product is evidence the Record Engine works for a specific decision domain. The Record Engine itself is decision-domain-agnostic.
The framing rule: GeoClear is an operational-evidence-record platform for machine decisions. We’ve built the Tier 2 products as the blueprints for how we issue tamper-evident operational evidence records in specific decision domains. If we can issue an operational evidence record for a flood verdict, we can apply the same record architecture to other machine decisions.

- Key Transparency ArchivePublic verification material across four channels.
- location-trust.jsonUnified trust-substrate manifest for verifier scripts.
- Security architectureTrust-boundary diagram + record issuance + honesty disclosure.

- Compliance briefAudit-heavy workflow surface.
What this Record Engine verifies, and what it doesn’t
What this verifies
- GeoClear issued this verdict at the record’s timestamp.
- The retained operational evidence matches the issued record.
- The retained verification material verifies the record.
- The record was not modified after issuance.
What this does not verify
- That every upstream dataset was perfect.
- Full legal or regulatory compliance.
- That a downstream business decision was risk-free.
- That the physical world matched the recorded values.
This is the right boundary. The Record Engine makes the verification path verifiable on the customer’s terms without overclaiming what cryptography can verify about the world.
Try it
The Record Engine issues operational evidence records for eligible GeoClear verdict responses across every public API surface, and produces records customers can retain. Three ways to see it:
