Editorial policy
Editorial content (titles, explanations, FAQs) lives apart from calculation rates. Money claims on content pages must reference registered sources or the live model version.
Authorship and review
Articles are written by Alan Lee (Founder & Editor) unless otherwise noted. Technical review checks scope vocabulary, model-version alignment, and unsupported-case language before publication.
Separation of concerns
Rate constants live in the cost engine with source IDs and review dates. Editorial modules never embed monetary constants that diverge from the model. Example tables on cost pages are generated from the engine.
Publishing status
Only content with status published generates routes and sitemap entries. Draft and technical_review records do not ship publicly. We do not publish thin regional doorway pages without distinct evidence and analysis.
Dates and corrections
Displayed content dates come from content metadata. Model dates come from MODEL_METADATA. Deploy time is never shown as a content or model date. Send corrections via the contact page.
