Phase 8 · National Property Graph

The shared intelligence foundation for every U.S. property.

The AIREx Property Graph replaces flat property tables with a living network — canonical identity, typed relationships, versioned regulation, evidenced observations, and append-only history — so every AIREx product answers the same questions from the same source of truth.

Pillar
STRUCTURAL
Canonical Identity
Every parcel receives a permanent AIREx Property ID — stable across owner, address, and provider changes.
Pillar
STRUCTURAL
Universal Relationships
27 typed relationships connect land, buildings, owners, rights, permits, projects, and infrastructure.
Pillar
STRUCTURAL
Append-only Event Ledger
Every material change is recorded. Corrections create new corrective events — nothing is silently overwritten.
Pillar
STRUCTURAL
Source Provenance
Every observation carries source, retrieval date, license, confidence, and verification status.
Pillar
STRUCTURAL
Conflict Preservation
Disagreements between sources are stored, queued for analyst review, and versioned — not resolved by overwrite.
Pillar
STRUCTURAL
Versioned AIRScore
A configurable 10-component scoring registry so models evolve without destroying historical scores.

Demonstration Data — Not a Verified Public Record. Live national data connectors are DEFERRED / BLOCKED pending credentials and licensing. Every simulated record is labeled as such throughout the platform.
One graph, every product
Digital Twin, Opportunity Engine, Deal Room, Reports — all read from the graph.

Every future AIREx feature operates from the shared Property Graph. Nothing is siloed; nothing is copied without provenance.
