- nws.js: new fetchActiveAdvisories() hits the official NWS alerts feed
(api.weather.gov /alerts/active?point=lat,lon) and normalizes each advisory
into the app's alert shape, tagged source:'nws'. Adds classifyAdvisoryEvent
(maps NWS events -> app buckets: heat/wind/cold/storm/precip, else advisory),
nwsSeverity (Extreme/Severe->danger etc.), advisoryId (stable short id from
the URN), advisoryIcon, and local effectiveDate/expiresDate for dedup.
- notifications store: cached _nwsAdvisories + refreshAdvisories() (best
effort, cached 5 min, non-US/no-alerts safe). analyze() now merges
advisories via new pure mergeAdvisories(): an advisory that is officially
in force on a date supersedes the derived forecast alert of the same type
on that date, so the official NWS warning replaces the forecast guess. Both
are dismissible independently (nws-* vs forecast-* ids).
- New per-type toggle "advisory" (defaults on) across app/default settings and
SettingsDialog, so official advisories are configurable like every other
alert and the bell shows them with their own severity/icon.
- Wired: App.svelte calls refreshAdvisories() alongside analyze() on forecast
load and changes.
- Tests: 12 advisory tests (classifier, severity, id, normalize, dedup incl.
disable toggle) + 3 store integration tests (overlap dedup, non-overlap kept,
toggle-off). 107 total pass.
- Verified end-to-end in headless Chromium against the live NWS feed for
Rogers County, OK: the current Heat Advisory appears in the bell, and the
derived heat alerts for the days it covers are suppressed while a
non-overlapping day's forecast heat alert remains.
