live1. Pin the work
Choose the record and say what you are actually going to do with it. The product re-reads the work live and stores a snapshot, so your docket records what the institution said today.
2. Read the arithmetic
Six weighted factors: the institution's own claim, the creator's term, the publication-age rule, the restrictions in their statement, your use, and whether a credit line is even possible.
3. Seal and export
Record the decision into a SHA-384 chain, then export a dated docket as JSON, CSV or Markdown with the credit line and the seal a colleague can re-verify.
