Cookbook: Pre-Parsed Value Extraction

Regex finds candidate emails, phone numbers, and amounts; Jev picks the requested span so code copies a verbatim value that cannot be invented, with no free-text extraction required.

Highlights

  • Jev only chooses among regex-found spans, so the returned value is copied verbatim and cannot be invented.
  • A receipt email was picked at 0.98, a cell number normalized to +14155550177, and an invoice total read as $1,315.50.
  • Amounts parse to Decimal in code, while a $50.00 courtesy credit was flagged at P(credit) 0.99.
  • find() over-finds and dedupes while pick() offers the spans as options plus a none hatch.

Watch out

Choice caps at 255 options, and candidates without a regex, such as names, must come from a roster, NER, or an LLM.
