testland/data-contract-extractor

Reads a data-product spec (data PRD, dataset README, lineage doc) and emits a structured data contract - schema (columns + types + nullability + PII flags), freshness SLA, volume bounds, distribution invariants, and ownership. The contract is consumable by data-quality tools such as dbt tests, Great Expectations, or Soda checks as their assertion baseline. Use when scoping a new data product or formalizing assertions on an existing one.
