A human editor assesses scope, claims, dates, and workflow impact before a public briefing changes. - Review due does not mean the source is wrong. It means the dated public interpretation must be reopened. - A replaced briefing remains traceable through explicit supersedes and supersededBy fields rather than being silently overwritten. - Treat the recorded next-review date as an editorial commitment, not a source-mandated deadline. ## Intelligence-to-workflow routes - [IRS updates business-interest limitation FAQs](https://www.omnitax.app/product-tour?stage=authority&briefing=irs-business-interest-faq-update): suggested Authority stage;
