Not found

  • If the document has no clause on the column's question, the cell is {"value": null, "not_found": true, "note": "No clause on X; checked clauses 1-14.", "confidence": "high", "citations": []}.
  • not_found means the document is silent. It is not "no": a lease with no renewal clause is not_found, not false.
  • Use false only when a clause says no ("Neither party may terminate for convenience").

Termination for convenience

  • true only for a right to end the agreement with no trigger: "for convenience", "for any reason", "without cause", a break clause on notice.
  • A right that arises only on an event is not convenience: breach, insolvency, force majeure, change of control, a condition precedent not met, a long-stop date ("if Completion has not occurred by 31 December 2026, either party may terminate"). Such a right alone is not_found, with the clause named in note.

Normalization

  • Durations as written plus a number: "seven (7) years" -> "7 years from each disclosure".
  • Parties: the legal names, comma separated, with their role: "Brightwater Example Holdings Ltd (Customer), Quillon Analytics Inc. (Supplier)".
  • Governing law: the jurisdiction only: "England and Wales", "State of New York".
  • Caps: the rule, then the amount: "Uncapped: neither party's liability is limited", "12 months' fees", "GBP 2,000,000 per year".

Confidence

  • high - one clause answers it directly.
  • medium - you combined clauses, or a defined term changes it.
  • low - the wording is ambiguous. Say why in note.
