Assignment Rules
We assign the level supporting the central claim, disclose weaker dependencies, and do not upgrade an article because an unrelated stronger source is present. Philippine regulation and licensing claims require relevant Level A support and Human Approval.
Freshness
Sources can become outdated or change scope. Last Verified and Next Review are separate from ordinary editorial update dates.
