Survival and healthspan are different outcomes. Population survival supplies a baseline. Healthy active years are an exploratory scenario and are never presented as a measured breed fact unless a study directly measured that endpoint.
Breed mappings fail closed. Exact normalized names and recorded human-approved aliases may inherit a cohort record. Fuzzy suggestions do not publish values.
Indexability requires page-specific evidence. A breed page enters the sitemap only when the cohort measure, sample, source identifier and mapping are present. A populated legacy JSON record is not enough.
Commercial separation. Affiliate status, sponsorship or a future owned product cannot alter evidence grades or eligibility for editorial inclusion.
Review status is literal. Until a named veterinary reviewer signs a version, the page says that medical review is not recorded.
