Mostert (G J)

Database-wide FirstName/Age contamination sweep (extension), 28 Sep 2026: FirstName 'Keith' and Age 51 were forward-filled from PersonNumber 39864 down a contiguous run of 2 records -- this record's own LastName ('Mostert'), Initials ('G J'), ServiceNo ('728541') and DateDeath ('1979-04-07') are all genuinely distinct, confirming a different real person whose FirstName/Age were simply never captured. Unlike the first pass of this sweep, Unit is NOT touched here -- it is not part of this contamination (see the Unit-restoration correction on the related run) and this record's own Unit ('1st Battalion') is left exactly as found. FirstName and Age CLEARED; no replacement guessed.
