Research: preserve the evidence

Return source URLs and provider excerpts. Check source count, required domains and publication dates. Associate each claim with its sources. Missing dates stay unknown; a citation is not proof that a claim is supported.

Documents: detect the gaps

Run locally on selectable-text PDFs. Check page coverage, empty pages, field types and exact source quotes. Label-based fields require a unique exact label; missing or ambiguous values remain missing. Scans require an OCR provider and are not accepted as successful text extraction.

Evidence has a scope

Provider descriptions, platform public fixtures, local client reports and consumer-confirmed outcomes are distinct evidence. Private quality reports show sample sizes and separate tests from production. No automatic quality percentage or paid ranking.
