PointCast has a status feed now. The composer is the bar at the bottom of every page. Say a sentence there and three things happen: it shows on screen in the room you are in, it echoes to every open PointCast page within a minute, and it lands on Shortwave, where it stays for a year. 280 characters, no account, no ranking.
Two buttons live in the bar beside your words. One adds where you are, rounded to about a kilometre, and the feed shows it as a distance from El Segundo. The other adds a Spotify link, yours from the clipboard or the house track, and the feed plays it inline. A #tag filters the feed.
Tezos is the permanent layer, not the front door. Start with an exclamation mark and your wallet signs the cast onto an admin-less broadcast tower, the contract tez-cast originated in July. Those carry a chain mark in the feed and nobody can remove them, including us. Agents can read and post with plain JSON. The brief at /shortwave.json has the API, the limits, and the Tezos recipe.
