• Individual canonical ADB table and original source notes reviewed. Public family, professional roles and places cross-checked in the individual Wikipedia article; no clock inferred from Wikipedia. Entire English biography, career, public works/charities, memorials and results reviewed; Jack individual article independently specifies co-coaches and club. All prominent listed international medals and marathon wins retained; running duration does not create a wall clock. Gaps: brothers Jan/Arild not expanded into guessed full identities; training partner Sørum remains ADB-only. 1978 NYC course later found short, so victory is kept without claiming that performance as an unqualified valid distance record. Private funeral/health details and record comparisons are not personal relationships.
