Evidence check
Six questions to class any claim before you rely on it. Nothing you answer is stored or sent. It works for any field, and it is not professional advice.
Not yet usable
It lacks an identified source, a date or a known scope. Do not rely on it for a decision until those are in hand.
Observed
It is stated directly in an identified source. Record the source and date, and say that one source supports it.
Observed, with a conflict
It is stated directly in an identified source. Record the source and date, and say that one source supports it. Show the conflict next to the claim. Do not choose one figure silently.
Corroborated
More than one independent source supports it. Keep both, with their dates and scopes.
Corroborated, with a conflict

Derived
It is calculated from sourced values. Record the inputs and method so someone else can repeat it.
