16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo '70223318' was CLEARED. It was not a reading of this man's record. PersonNumbers 33789 to 33791 -- 3 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (33789, Wallis, Charles William Peter (C W P)). A value repeated down an unbroken block of PersonNumbers is a forward-fill import artefact, not men who shared a service number; the pattern holds across 850 such runs on this roll and is independently confirmed by Mike Sandham's research log, which attaches such numbers to the head of the run 167 times against 6 contradictions (all examined). No replacement is guessed: this man's real service number is simply not known, and a blank field says so honestly where another man's number did not.
25 Sep 2026, Unit2 service-branch sweep: the stored Secondary Unit "Air Force" was CLEARED. It was not a sub-unit, it was a service-branch word, and it CONTRADICTED this record's own Branch, "Army". Across the roll 787 records carried such a contradiction; judged against Corps and Regiment -- independent of both columns -- the evidence backed Branch 744 times and Unit2 not once. Branch is therefore kept and the contradicting word removed. Nothing is guessed: this man's branch of service is already recorded, and his sub-unit, if any, is simply not known.
