16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo 'P/20304' was CLEARED. It was not a reading of this man's record. PersonNumbers 41715 to 41716 -- 2 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (41715, Kleynhans, Evert Philippus Jacobus (E P J)). 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.
14 Oct 2026: Col (rt) Graham du Toit Last Post, 14 Oct 2026, gives the fuller account: a truck collided with his bicycle while he was pedalling to work; rushed to 1 Military Hospital, where he died shortly after admission -- consistent with the stored "Voortrekkerhoogte Military Hospital" (1 Military Hospital's own location). Rank, date, age and cause already matched.
14 Oct 2026: UNIT CONFLICT, NOT CHANGED: stored Unit "Pay Branch"; Col (rt) Graham du Toit Last Post, 14 Oct 2026, instead names "1 Air Depot". Not cleared as contamination: although "Pay Branch" is shared across a run of five records (41711-41713, 41715-41716), broken only by one differing record (41714), Unit values have not been established as part of this roll's forward-fill signature (see the 28 Sep sweep correction) and "Pay Branch" is a plausible genuine shared posting, not an obviously fabricated value -- flagged for review rather than cleared. ServiceNo, date, age and cause already matched.
