AirNow remained accessible with AQI, wildfire, fire-and-smoke, state, map, API, mobile-app, and activity-guide links while CDC heat dashboards were down. [1]

AirNow provides the source record; no verified same-session X post is attached, so the article treats the public record as the evidence. [2]

The reader task is narrow: keep the public record in view, and do not let a summary substitute for the document, label, count, schedule, method, product name, lot number, public tally, governing line, affected place, or household action that can actually be checked. [1] [2] [3]

That is enough for a brief because the useful news is practical: AirNow supplies the record, no verified same-session X post is attached, and the public value is knowing exactly what to verify next before the story becomes another generic warning, market slogan, or institutional talking point detached from the person who has to act.

If the next update changes the product, source date, public count, schedule, vote, measurement method, named actor, affected route, or consumer instruction, the story changes; if it only changes the volume of the argument, it does not.
