# Catch the gaps before an officer does *Gap & consistency checks* — Lexova checks every personal history and address history for uncovered months, overlapping periods and locations that contradict each other — and refuses to let a form be submitted until every uncovered month is filled in and every overlap or conflict is fixed or explained. A one-month hole in a ten-year history is the kind of thing that surfaces as a procedural fairness letter months later. Finding it by hand, across a family of applicants, is exactly the work software should do. Lexova walks each timeline month by month, inside the window IRCC actually asks about — the last ten years, or since the applicant turned 18, whichever is more recent — and stops the form from being submitted with a hole in it. ## How it works 1. **Continuous coverage, checked by month** — Personal history is checked month by month: an activity ending 1 October followed by one starting 1 November is continuous, but a month nobody accounted for is flagged by name. Address history is checked to the day. 2. **Contradictions surfaced** — Overlapping activities in different cities, and addresses that disagree with where the client says they worked or studied, are raised as one clear question per entry — not a wall of duplicates. 3. **Fix it, or explain it — before submitting** — A missing period must be filled; there is no way to talk past it. A contradiction may instead be explained in the client's own words, and Lexova AI checks that the explanation actually answers the question before accepting it. ## Why it matters - **No silent holes** — Forms cannot be submitted with an uncovered month, so the timeline you file is continuous by construction. - **Explanations on file** — Legitimate overlaps come with the client's own written explanation, captured while the facts are fresh — ready if IRCC ever asks. - **Straight to the problem** — Every warning carries a button that opens the exact section and row it refers to, for the right applicant. - **Reviewed, not rubber-stamped** — Filler answers are refused, and your coherence check re-tests every explanation against the uploaded documents. ## Histories filed newest-first, automatically Clients rarely enter their history in order. Personal history, address history, employment and travel tables are re-sorted most-recent-first the moment they are saved — on screen and in the generated IRCC PDF — so the officer reads the timeline the way the form expects it, and the gap check runs on the same ordered rows. Nothing is retyped and no entry is lost; only the order changes. ## Questions ### What counts as a gap? In personal history, a calendar month that no entry touches, inside the last ten years or since the applicant's 18th birthday — whichever is more recent. Address history is stricter and checked to the day. ### Can a client explain away a missing period? No. Gaps must be filled — even with "unemployed" or "job search", which are perfectly acceptable answers. Only contradictions are explainable. Documents that contradict the forms?
