 Hook it up to an LLM and it becomes a **two-way intelligence assistant**: pushing multi-tier alerts to Telegram and Discord when something meaningful changes, responding to commands like `/brief` and `/sweep` from your phone, and generating trade ideas grounded in real cross-domain data.

 - Do not commit `runs/` or `.env`. API credentials stay in `.env`; memory stores derived observations, not secrets.
 - If you expose the dashboard through a reverse proxy, protect Terminal Actions and memory queries behind your normal authentication boundary.
 
+#### Reverse Proxy SSE
+
+The dashboard receives live sweep updates from `GET /events` using Server-Sent Events. The server sends `retry: 10000` reconnect guidance and lightweight heartbeat comments every `SSE_HEARTBEAT_INTERVAL_MS` milliseconds so reverse proxies do not close an otherwise idle stream between 15-minute sweeps.
+
+Recommended proxy settings:
+
+| Proxy | Setting |
+| --- | --- |
+| Pangolin / Traefik-style frontends | Keep response streaming enabled and set idle timeouts above `SSE_HEARTBEAT_INTERVAL_MS`. |
+| Nginx | Disable proxy buffering for `/events`, keep `proxy_read_timeout` above the heartbeat interval, and preserve `Connection: keep-alive`. |
+| Cloudflare-style proxies | Keep the heartbeat below common idle cutoffs; the default 25s is intentionally conservative. |
+
+If you raise the heartbeat interval, keep it shorter than the lowest idle timeout in the proxy chain.
+
 #### Scenario Watchlist
 
 Intelligence Terminal can track operator hypotheses across sweeps with a runtime scenario file at `runs/scenarios.json`. On first run, the server creates three disabled starter examples:

 ## What You Get
 
 ### Live Dashboard
-A self-contained Jarvis-style HUD with:
+A self-contained app-style operator dashboard with dark mode by default, a large left navigation rail, rounded content surfaces, and view-specific panels:
-- **3D WebGL globe** (Globe.gl) with atmosphere glow, star field, and smooth rotation — plus a classic flat map toggle
+- **Home** - sweep status, alert posture, latest feed, source count, macro summary, and high-level signal state
-- **9 marker types** across both views: fire detections, air traffic, radiation sites, maritime chokepoints, SDR receivers, OSINT events, health alerts, geolocated news, conflict events
+- **Worldview** - Globe.gl 3D globe or flat map, regional focus controls, 9 marker types, flight corridors, and layer focus/hide controls
-- **Animated 3D flight corridor arcs** between air traffic hotspots and global hubs
+- **Sources** - sensor grid, source health, API-key degradation signals, and transparent partial-data states
-- **Region filters** (World, Americas, Europe, Middle East, Asia Pacific, Africa) — rotates the globe or zooms the flat map
+- **Signals** - cross-source signals, sweep delta, scenario watchlist, OSINT feed, and escalation/de-escalation context
-- **Live market data** — indexes, crypto, energy, commodities via Yahoo Finance (no API key needed)
+- **Markets** - live indexes, crypto, energy, commodities, VIX, high-yield spread, supply-chain pressure, and LLM-assisted ideas
-- **Risk gauges** — VIX, high-yield spread, supply chain pressure index
+- **Ops** - browser-triggered terminal actions, performance mode, Telegram/Discord operator workflows, and system status
-- **OSINT feed** — English-language posts from 17 Telegram intelligence channels (expandable)
+
-- **News ticker** — merged RSS + GDELT headlines + Telegram posts, auto-scrolling
+The UI keeps the existing operational features: `/api/data`, SSE live refresh, globe/flat map mode, layer focus/hide, terminal actions, low-performance mode, LLM output, Telegram and Discord alerting, and scenario watchlist data.
-- **Sweep delta** — live panel showing what changed since last sweep (new signals, escalations, de-escalations with severity)
-- **Cross-source signals** — correlated intelligence across satellite, economic, conflict, and social domains
-- **Nuclear watch** — real-time radiation readings from Safecast + EPA RadNet
-- **Space watch** — CelesTrak satellite tracking: recent launches, ISS, military constellations, Starlink/OneWeb counts
-- **Leverageable ideas** — AI-generated trade ideas (with LLM) or signal-correlated ideas (without)
 
 ### Performance Modes
 The `VISUALS FULL` / `VISUALS LITE` button in the top bar only changes rendering behavior - it does **not** remove data sources or reduce sweep coverage.
 
 When you switch to **VISUALS LITE**, the dashboard:
-- Disables decorative background effects such as the radial/grid overlays and scanlines
+- Disables decorative background effects such as radial and grid overlays
 - Removes expensive blur/backdrop-filter effects on panels and overlays
 - Stops non-essential animations like the logo ring blink, conflict rings, and corridor flow effects
 - Disables globe auto-rotation and turns off animated flight-arc dashes
