Changed the definition of "get_feed"
The Helious feed, newest first: the posts Helious publishes:scored(kind post: releases with their surprise, auction results, board updates, the daily brief and live squawklines.lines)Postsand the wire headlines it carries (kind headline: breaking news, geopolitics, official statements, central bank speakers, bank and business notes). Every item has a stable id, a score and a direction; most carry helious_read,the desk'sHelious's plain-English line on why it matters. A headline also carries carried_at (when Helious put it on the tape; created_at is when it was published) and a URL-free thread_id that stays the same when a story is retitled. No headline names its outlet, author or link. Depth follows your plan (1 day keyless, 7 days free, 12-24 months paid, 10 years Ultimate).for the permanent posts: releases, auctions, desk posts, the brief, the minutes. Headlines are kept 7 days whatever the plan (official statements and Fed speakers 400 days), as are squawk lines and the board lanes. Optional q filters by word; categories narrows to chosenlanes.lanes; kind narrows to headline or post. Delayed 60 minutes without a paid key.
