Sources and data policy
CostMage prefers official statistical series and published fee tables. Marketplace or survey sources are used only when labeled, and only for facts they actually state.
Each cost page lists publisher, title, URL, source date, data period, last verification, and licensing status. Factual figures may be restated. We do not copy protected narrative wholesale.
Licensing statuses in the data model are SAFE_FACTUAL_USE, SAFE_WITH_ATTRIBUTION, REVIEW_REQUIRED, and DO_NOT_USE. Records with core licensing blockers are not allowed in the active cohort.
Citing a government agency or publisher does not mean CostMage is affiliated with that organization.
