Each detected order is organized by location, authority, start date, end date, and source so the current status is easier to read.
Mast is informational, so active orders include a source link when available and should be verified with the official notice when it matters.

Colorado publishes a dedicated current Flag Status page with ephemeral full-staff or half-staff status and official Governor news posts for dated half-staff directives. 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, and parses dated Governor news posts when discoverable.
Mast answers a common question quickly: should a flag be at half-staff or full-staff today? The page shows the current status, the relevant authority, date range, and source when a known order is available.
