Covacha (A C)

DateDeath was 1900/1901-01-01 SAWGP unknown-date placeholder; set to Unknown. EstBirthYear derived from that date cleared. SN CORRECTION 25 Aug 2026: ServiceNo 74430166BT cleared -- the pantser.cmvo.org.za SADF deaths PDF lists that number under "COUVELIS, FRANK PAUL" (RFN, Sterf 12 05 83), matching PersonNumber 29855 (Couvelis, DateDeath 1983-05-12) by surname and exact date, not this record. Original value: "74430166BT". Left as an unresolved collision otherwise -- this correction is specific to this one PDF-confirmed case, not a general claim this record's other data is wrong.
FirstName contamination fixed 31 Aug 2026 (systemic full-table scan): FirstName ("Frank Paul") was copied from the unrelated neighbouring record PersonNumber 29855 ("Couvelis, Frank Paul", initials F P) -- this record's own stored initials (A C) don't match "Frank Paul" at all. Confirmed by the existing 25 Aug 2026 SN CORRECTION note on this record, which already identified PersonNumber 29855 as the true owner of this record's copied ServiceNo via the same external source. Cleared back to unknown rather than guessed, AddInfo (also an exact copy from the same neighbour) cleared likewise.
4 Sep 2026: Regiment leftover "SA Army" cleared -- that's the service branch (Army, as distinct from Navy/Air Force), not a specific regiment; the actual unit ("912 Battalion") is already captured in Unit. Per John's decision, the 52 records with no better Unit info were left as-is.
7 Sep 2026: CauseDeath was a forward-fill copy from PN 29855 (Couvelis, Frank Paul (F P)), an unrelated record -- cleared as contamination (CauseDeath-contamination scan, data/causedeath-contamination-scan-2026-09-07.md), not a real cause.
