Metis — Verify Claim
verify_claimCheck whether a claim's cited document, page, figures, and quoted text actually exist in the indexed corpus using deterministic rules only, with no model to hallucinate a verdict.
Instructions
Tier A — check a claim against the indexed corpus, deterministically.
Verifies what can be verified WITHOUT a model: that the cited document is
indexed, that the cited page exists, that the claim's figures appear on that
page, and that any quoted string is actually present. It cannot hallucinate a
verdict because it contains no model.
A `supported` verdict means the deterministic checks passed. It does NOT mean
the passage supports the claim — that is entailment (Tier C, Critic's job).
For a source that is not in the corpus, use `verify_doi` to establish whether
it exists at all.
Args:
claim: The sentence or statement being checked.
source: Cited document title or filename, as written in the answer.
page: Cited page number; 0 or omitted searches the whole document.
quote: An exact quotation to locate, if the claim contains one.
record: Append the verdict to the citation ledger (default True).
Returns:
The verdict, what was tested, and which figures (if any) were missing.
