Mast tracks current federal flag orders and known Texas local orders so residents, public buildings, schools, businesses, and local websites can quickly check whether flags should be at half-staff or full-staff today.
The Texas source in Mast is Texas Governor / gov.texas.gov, categorized as Official Governor Flag Status And Newsroom.
Texas has an official source Mast can check for current flag status. Mast also uses the source to track historical Texas half-staff notices when dated orders are available.
Texas publishes ephemeral current flag status through the official Governor flag-status page and dated half-staff directives as Governor news posts. The importer reads the live flag-status signal first, creates an observed same-day event if that page reports half-staff without a matching dated notice, discovers recent half-staff notices from the Governor news index, and parses statewide, state-government, and local orders with through-sunset, return-at-sunrise, and within-ten-days windows.
