Principle 01 of 05
Property-first
Anchored to a durable property identity.

What this means
Why it matters
Everything Property Spine does starts from the property. Anchoring to UPRN where appropriate makes the record durable, joinable and auditable across every participant in the lifecycle.
In practice
Workflow implications
Identity is resolved once and reused, not re-matched at every hand-off.
Match quality is scored and visible.
Every fact, inference and action traces back to the same property.
The layer
How this shapes Property Spine
Property Spine is built around the property record, not around any single workflow or participant. That is what makes the intelligence reusable.
