# Unknowns & limitations

> Retain unresolved questions and source limits without inventing certainty.

## Unknown is a useful result

Unknown is not false, zero or recently verified. A source-dependent collection may be null when it was not assessed. An empty collection alone does not prove no relationship exists.

A source statement is not an independently verified fact. Preserve contradictory evidence and missing dates. No confidence score or chain-of-thought is part of this contract.
