What an account leaves out may still matter.

Aperture here means the route through which information becomes available: a sensor, document, conversation or selected search. Source selection is part of that route. A wider search may add missing evidence, noise, or more copies of the same source. A failed search or fetch does not by itself show that its target is absent, unsafe or inactive. Keep the observed result, a report of that result, and an explanation of its cause distinct. Before changing the target, ask what this route could actually detect.
Another position
A formal record and a lived account can each contain facts unavailable to the other. Neither is automatically complete or correct.
Challenge
Different viewpoints do not make incompatible factual claims equally supported. Independent checking still matters; imagining another view is not obtaining its testimony. Non-detection can support absence when a check's coverage, timing and ability to detect the target are established. A successful check through another route does not prove the first route works.
Open question
What could this route fail to show, and what would establish it?
