What this server can do
4 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
audit_rows(rows)- Audit spreadsheet-like rows for footing, balance-sheet ties, common margins, and cell provenance. Required: rows.
covenant_rules(rows, rules, rule_pack)- Evaluate threshold/covenant rules over spreadsheet-like rows with provenance. Use either rules or rule_pack. Required: rows.
diff_rows(rows_after, rows_before)- Compare two report versions by numeric row labels with provenance. Required: rows_before, rows_after.
verify_claim(claim)- Exactly verify a math/finance claim (VERIFY/REFUTE/ABSTAIN) with a counterexample when false. Use before trusting any AI-produced number, sum, percentage, or formula. Required: claim.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
