Mast watches federal and state flag-status sources for half-staff orders, observances, and official notices.
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.
Half-staff means lowering the flag below the top of the staff as a sign of mourning, remembrance, or honor for the period named in an official order.

The Puerto Rico source in Mast is Puerto Rico Department of State / Governor, categorized as Official Governor Newsroom And Decrees Archive. Puerto Rico does not publish a dedicated current-status page in the source registry, so Mast checks official notices and dated directives. Mast also uses the source to track historical Puerto Rico half-staff notices when dated orders are available.
Puerto Rico publishes recent Spanish-language Governor flag-lowering notices through La Fortaleza press releases and older official decrees through the Department of State decrees archive. The importer discovers Governor press notices, parses media asta directive text, Spanish date ranges, one-day mourning notices, nonconsecutive listed lowering dates, and archive decree rows; events are marked for LLM enrichment so titles and reasons can be normalized for English-facing Mast surfaces.
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.
