Exercise 3: An Outdated Electoral Roll Entry Isn't a Behavioral Problem — Possible Solution
====================================================================

The specific real effect here is a missing identity-verification
signal, not a mark against this person's actual financial behavior.
The electoral roll is a real, standard part of how a UK credit
reference agency verifies identity and address history - not being
registered at the current address removes that particular signal from
the credit file, which can make it harder for a lender to confirm who
this person is and where they currently live, separate from anything
about how responsibly they've actually managed credit.

This genuinely doesn't reflect their actual financial behavior because
excellent payment history and low credit utilization are real,
positive indicators of exactly the kind of responsible credit use
lenders care about - neither of those is affected by an outdated
electoral roll entry at all. The missing electoral roll registration
is a separate, administrative gap rather than a sign of financial
mismanagement, and it's a real, simple gap to fix by updating the
registration at the new address.

ANSWER: The specific real effect is a missing identity-verification
signal in this person's credit file, not a mark against their actual
financial behavior - their strong payment history and low utilization
remain genuinely positive and unaffected. The electoral roll gap is
an administrative issue (identity/address verification), separate from
and unrelated to how responsibly they've actually managed credit, and
is fixed simply by updating the registration.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly separates the electoral roll's real identity-
verification role from the person's actual credit behavior, explaining
why the gap exists without incorrectly treating it as evidence of poor
financial management.
