16.1Decision rule
// routing pattern
IF certificates_of_immunity > risk_tolerance -> route to physical risk review

The rule is a pattern, not a policy - you set the operator and the cut-off to your own appetite. On the sample record this field returns [], the kind of value a rule like the above turns into a physical-risk review or a pass.

16.2Where it bites
01

Physical-risk views for supervisory and disclosure work.

02

Portfolio hazard concentration, measured at the address rather than the postcode.

03

Case-level routing where the risk is material.

16.3Provenance

A deterministic spatial join at the property point - a dot, not a postcode - rather than a declared or modelled attribute. Refresh is yearly, rendered from the dictionary rather than assumed.

Covered across Great Britain. Northern Ireland leads with attributes and rebuild, and this layer is GB-today - the coverage column says so rather than implying parity.
