Truth First means Q tries to keep claims connected to evidence, uncertainty, provenance, dates, contradictions, and correction paths.
An AI answer is not treated as evidence merely because it is fluent or confident. Q asks what supports the claim, what conflicts with it, how fresh the source is, and what should happen when evidence is missing.
Truth First is not a promise that Q or any AI will always be correct. It is a discipline for making support, uncertainty, and correction easier to inspect.
