Sources and data governance

Source types include official publications, supplier-published data, installer submissions, user submissions, verified quotations, and SolarGabay planning estimates. Each record should show observation date, location and product scope, confidence, review date, and expiry.

Solar price and installer records are administered in Supabase. Public pages show only published, current records; installer verification and sponsorship remain separate. Public-source checking confirms listed public details, not workmanship or customer outcomes.

Expired records are labeled or excluded. Public users cannot modify approved records directly, sponsorship cannot change source quality or verification, and every administrative change is written to an audit log.
