IF header_tank_probability != 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 "very low", the kind of value a rule like the above turns into a verification prompt or a pass.

01

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

02

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

03

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

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.
