Evidence Is Contextual

Evidence is not a free-floating fact. Something becomes evidence in relation to a question, claim, or model.

The same observation may support one proposition, weaken another, and remain irrelevant to a third. QLens therefore records relationships rather than treating evidence as a universal label.

Good evidence records preserve:

• the underlying observation or source;
• provenance and acquisition context;
• verification state;
• the proposition or question to which it is relevant;
• limits on what it can support;
• conflicts with other evidence.

Evidence should not contain more certainty than its source permits. A weak source remains weak even when it supports a preferred conclusion.
