Policy timeline

Each policy record should retain original document, issuing body, date, reference identifier, applicable object, and status. Secondary interpretation can be a lead but should not replace original text or be treated as still effective without a date.

Consultation, plan, guidance, implementation detail, and effective rule have different effects. A timeline should make status explicit and link revisions when later revisions appear, avoiding treatment of a historical draft or headline as a current mandatory requirement.

Policy can affect research direction, project process, market access, or disclosure, but actual impact also depends on local implementation, product coverage, and supporting documents. Analysis should state conditions and uncertainty rather than turn policy text directly into company orders or market-size conclusions.
