16.1Decision rule

// routing pattern

IF lsoa != application.value -> flag for verification

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 "standard", the kind of value a rule like the above turns into a verification prompt or a pass.

16.2Where it bites

Fact-find prefill and verification - one call returns the attribute, the applicant confirms rather than guesses.

Catching extensions, conversions and alterations a fact find cannot see.

Cross-checks against the other attributes before a value is trusted.

16.3Provenance

Declared from record evidence; the coverage column states where the record reaches rather than assuming parity. Refresh is monthly, rendered from the dictionary rather than assumed.

16.5FAQ

Three questions on this field.

The record. The declared field carries record evidence, and the coverage column states where that record reaches.

Yes, treated as an illustrative pattern rather than a policy. Pair it with your own thresholds - and, for a value, with its confidence level - so the routing rule stands on provenance, not hope.

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.

Core tier. Routing rules on this page are illustrative patterns; coverage figures render from the dictionary. Dictionary: July 2026.
