  The **Arena** tab (`/arena`) is the site's drama desk and competitive board, in the owner's words "drama alert type competitive shit … based on streamer activity". It replaced the mic-only Battle Cam home (v3, 2026-09-10): the mic still feeds it (beefs, the judged lines), and now so does everything else streamers measurably do.
  
--- **ARENA ALERT** (`server/arena/drama.js`, `public/js/arena-alert.js`) — every 5 min the desk reads the last 3 hours of activity and writes one story per event (`arena_drama`, deduped): **rage quits** (a stream over in < 15 min from someone who usually goes 45+), **viewer crashes** (halved within 20 min, from 3+) and **spikes** (doubled, to 4+), **chat explosions** (3× the stream's usual rate, 15+ in 5 min), **meltdowns** and **tears** (3+ yells/screams/shouts, or sobs, within 2 min on the sound timeline, quoted with what was said around them), **marathons** (8 h+), **ghost towns** (an hour+ to 0-1 viewers and no chat), **comebacks** (14+ days away), **title drama**, **new personal peaks**; once a day **fell off** (4+ streams the month before, none for 7 days), **no days off** (every 7 days in a row) and the **quote of the day**; beefs report their opening, win and forfeit. A story gets a template headline at once (facts and numbers only) and an AI rewrite from OpenVibe.AI's `live.arena.drama` (≤ 20 an hour): drama-news voice, roast what happened on stream, never invent an event or accuse, no identity slurs, sexual content, threats, doxxing or self-harm jokes; quotes are the streamer's own words. Alert level 1-5 (🚨). A subject with alert ≥ 3 is notified.

Alert level 1-5 (🚨). A subject with alert ≥ 3 is notified, and the story is announced in chat as **ARENA ALERT** (their stream room, mirrored to global chat, while they are live; else global chat; at most 6 an hour).
  - **Reactions** — 🔥 💀 🤡 W L, one per viewer per story (`arena_drama_reactions`; the person, else a salted address hash).
  - **Lolcow Index** — cow points from stories over the last 7 days (newer counts more; rage quits, crashes, meltdowns, tears, ghost towns, dramatic titles, falling off, ducking a beef), 0-100 against the top cow, who wears the 🐄.
  - **Clout Rankings** — the last 7 days: hours live ×2 + average viewers ×10 + peak ×3 + chat messages ÷ 50 + new followers ×5 + the clout points of their stories (spikes, records, comebacks, streaks, beef wins) + beef wins ×10 − half their cow points. This week's moves against the snapshot taken each Monday (`arena_clout_weeks`); tags COOKED (cow meter 70+), ON THE RISE, FALLING, UNDEFEATED.
