+# Intercept Distributed Agent System
+
+This document describes the distributed agent architecture that allows multiple remote sensor nodes to feed data into a central Intercept controller.
+
+## Overview
+
+The agent system uses a hub-and-spoke architecture where:
+- **Controller**: The main Intercept instance that aggregates data from multiple agents
+- **Agents**: Lightweight sensor nodes running on remote devices with SDR hardware

+```
+
+## Quick Start
+
+### 1. Start the Controller
+
+The controller is the main Intercept application:
+
+```bash
+cd intercept
+python app.py
+# Runs on http://localhost:5050
+```
+
+### 2. Configure an Agent
+
+Create a config file on the remote machine:
+
+```ini
+# intercept_agent.cfg
+[agent]
+name = sensor-node-1
+port = 8020
+allowed_ips =
+allow_cors = false
+
+[controller]
+url = http://192.168.1.100:5050
+api_key = your-secret-key-here
+push_enabled = true
+push_interval = 5
+
+[modes]
+pager = true
+sensor = true
+adsb = true
+wifi = true
+bluetooth = true
+```
+
+### 3. Start the Agent
+
+```bash
+python intercept_agent.py --config intercept_agent.cfg
+# Runs on http://localhost:8020
+```
+
+### 4. Register the Agent
+
+Go to `http://controller:5050/controller/manage` and add the agent:
+- **Name**: sensor-node-1 (must match config)
+- **Base URL**: http://agent-ip:8020
+- **API Key**: your-secret-key-here (must match config)
+
+## Architecture
+
+### Data Flow
+
+The system supports two data flow patterns:
+
+#### Push (Agent → Controller)
+
+Agents automatically push captured data to the controller:
+
+1. Agent captures data (e.g., rtl_433 sensor readings)
+2. Data is queued in the `ControllerPushClient`
+3. Agent POSTs to `http://controller/controller/api/ingest`
+4. Controller validates API key and stores in `push_payloads` table
+5. Data is available via SSE stream at `/controller/stream/all`
+
+```

+
+The controller can also pull data on-demand:
+
+1. User selects agent in UI dropdown
+2. User clicks "Start Listening"
+3. Controller proxies request to agent
+4. Agent starts the mode and returns status
+5. Controller polls agent for data

+
+### Authentication
+
+API key authentication secures the push mechanism:
+
+1. Agent config specifies `api_key` in `[controller]` section
+2. Agent sends `X-API-Key` header with each push request
+3. Controller looks up agent by name in database
+4. Controller compares provided key with stored key
+5. Mismatched keys return 401 Unauthorized
+
+### Database Schema
+
+Two tables support the agent system:
+
+```sql
+-- Registered agents
+CREATE TABLE agents (
+    id INTEGER PRIMARY KEY,
+    name TEXT UNIQUE NOT NULL,
+    base_url TEXT NOT NULL,
+    api_key TEXT,
+    capabilities TEXT,      -- JSON: {pager: true, sensor: true, ...}
+    interfaces TEXT,        -- JSON: {devices: [...]}
+    gps_coords TEXT,        -- JSON: {lat, lon}
+    last_seen TIMESTAMP,
+    is_active BOOLEAN
+);
+
+-- Pushed data from agents
+CREATE TABLE push_payloads (
+    id INTEGER PRIMARY KEY,
+    agent_id INTEGER,
+    scan_type TEXT,         -- pager, sensor, adsb, wifi, etc.
+    payload TEXT,           -- JSON data
+    received_at TIMESTAMP,
+    FOREIGN KEY (agent_id) REFERENCES agents(id)
+);
+```
+
+## Agent REST API
+
+The agent exposes these endpoints:
+
+| Endpoint | Method | Description |

+      }
+    }
+  }
+}
+```
+
+## Supported Modes
+
+All modes are fully implemented in the agent with the following tools and data formats:
+
+| Mode | Tool(s) | Data Format | Notes |
+|------|---------|-------------|-------|
+| `sensor` | rtl_433 | JSON readings | ISM band devices (433/868/915 MHz) |
+| `pager` | rtl_fm + multimon-ng | POCSAG/FLEX messages | Address, function, message content |
+| `adsb` | dump1090 | SBS-format aircraft | ICAO, callsign, position, altitude |
+| `ais` | AIS-catcher | JSON vessels | MMSI, position, speed, vessel info |
+| `acars` | acarsdec | JSON messages | Aircraft tail, label, message text |
+| `aprs` | rtl_fm + direwolf | APRS packets | Callsign, position, path |
+| `wifi` | airodump-ng | Networks + clients | BSSID, ESSID, signal, clients |
+| `bluetooth` | bluetoothctl | Device list | MAC, name, RSSI |
+| `rtlamr` | rtl_tcp + rtlamr | Meter readings | Meter ID, consumption data |
+| `dsc` | rtl_fm (+ dsc-decoder) | DSC messages | MMSI, distress category, position |
+| `tscm` | WiFi/BT analysis | Anomaly reports | New/rogue devices detected |
+| `satellite` | skyfield (TLE) | Pass predictions | No SDR required |
+| `listening_post` | rtl_fm scanner | Signal detections | Frequency, modulation |
+
+### Mode-Specific Notes
+
+**Listening Post**: Full FFT streaming isn't practical over HTTP. Instead, the agent provides:
+- Signal detection events when activity is found
+- Current scanning frequency
+- Activity log of detected signals
+
+**TSCM**: Analyzes WiFi and Bluetooth data for anomalies:
+- Builds baseline of known devices
+- Reports new/unknown devices as anomalies
+- No SDR required (uses WiFi/BT data)
+
+**Satellite**: Pure computational mode:
+- Calculates pass predictions from TLE data
+- Requires observer location (lat/lon)
+- No SDR required
+
+**Audio Modes**: Modes requiring real-time audio (airband, listening_post audio) are limited via agents. Use rtl_tcp for remote audio streaming instead.
+
+## Controller API
+
+### Agent Management
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/controller/agents` | GET | List all agents |
+| `/controller/agents` | POST | Register new agent |
+| `/controller/agents/{id}` | GET | Get agent details |
+| `/controller/agents/{id}` | DELETE | Remove agent |
+| `/controller/agents/{id}?refresh=true` | GET | Refresh agent capabilities |
+
+### Proxy Operations
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/controller/agents/{id}/{mode}/start` | POST | Start mode on agent |
+| `/controller/agents/{id}/{mode}/stop` | POST | Stop mode on agent |
+| `/controller/agents/{id}/{mode}/data` | GET | Get data from agent |
+
+### Push Ingestion
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/controller/api/ingest` | POST | Receive pushed data from agents |
+
+### SSE Streams
+
+| Endpoint | Description |
+|----------|-------------|
+| `/controller/stream/all` | Combined stream from all agents |
+
+## Frontend Integration
+
+### Agent Selector
+
+The main UI includes an agent dropdown in supported modes:
+
+```html
+<select id="agentSelect">
+    <option value="local">Local (This Device)</option>
+    <option value="1">● sensor-node-1</option>
+</select>
+```
+
+When an agent is selected:
+1. Device list updates to show agent's SDR devices
+2. Start/Stop commands route through controller proxy
+3. Data displays with agent name badge
+
+### Multi-Agent Mode
+
+Enable "Show All Agents" checkbox to:
+- Connect to `/controller/stream/all` SSE
+- Display combined data from all agents
+- Show agent name badge on each data item
+
+## GPS Integration
+
+Agents can include GPS coordinates with captured data:
+
+1. Agent connects to local `gpsd` daemon
+2. GPS position included in `/capabilities` and `/status`
+3. Each data snapshot includes `agent_gps` field
+4. Controller can use GPS for trilateration (multiple agents)
+
+## Configuration Reference
+
+### Agent Config (`intercept_agent.cfg`)
+
+```ini
+[agent]
+# Agent identity (must be unique across all agents)
+name = sensor-node-1
+
+# Port to listen on
+port = 8020
+
+# Restrict connections to specific IPs (comma-separated, empty = all)
+allowed_ips =
+
+# Enable CORS headers
+allow_cors = false
+
+[controller]
+# Controller URL (required for push)
+url = http://192.168.1.100:5050
+
+# API key for authentication
+api_key = your-secret-key
+
+# Enable automatic data push
+push_enabled = true
+
+# Push interval in seconds
+push_interval = 5
+
+[modes]
+# Enable/disable specific modes
+pager = true
+sensor = true
+adsb = true
+ais = true
+wifi = true
+bluetooth = true
+```
+
+## Troubleshooting
+
+### Agent not appearing in controller
+
+1. Check agent is running: `curl http://agent:8020/health`
+2. Verify agent is registered in `/controller/manage`
+3. Check API key matches between agent config and controller registration
+4. Check network connectivity between agent and controller
+
+### Push data not arriving
+
+1. Check agent status: `curl http://agent:8020/status`
+   - Verify `push_enabled: true` and `push_connected: true`
+2. Check controller logs for authentication errors
+3. Verify API key matches
+4. Check if mode is running and producing data
+
+### Mode won't start on agent
+
+1. Check capabilities: `curl http://agent:8020/capabilities`
+2. Verify required tools are installed (check `tool_details`)
+3. Check if SDR device is available (not in use by another process)
+
+### No data from sensor mode
+
+1. Verify rtl_433 is running: `ps aux | grep rtl_433`
+2. Check sensor status: `curl http://agent:8020/sensor/status`
+3. Note: Empty data is normal if no 433MHz devices are transmitting nearby
+
+## Security Considerations
+
+1. **API Keys**: Always use strong, unique API keys for each agent
+2. **Network**: Consider running agents on a private network or VPN
+3. **HTTPS**: For production, use HTTPS between agents and controller
+4. **Firewall**: Restrict agent ports to controller IP only
+5. **allowed_ips**: Use this config option to restrict agent connections
+
+## Dashboard Integration
+
+Agent support has been integrated into the following specialized dashboards:
+
+### ADS-B Dashboard (`/adsb/dashboard`)
+- Agent selector in header bar
+- Routes tracking start/stop through agent proxy when remote agent selected
+- Connects to multi-agent stream for data from remote agents
+- Displays agent badge on aircraft from remote sources
+- Updates observer location from agent's GPS coordinates
+
+### AIS Dashboard (`/ais/dashboard`)
+- Agent selector in header bar
+- Routes AIS and DSC mode operations through agent proxy
+- Connects to multi-agent stream for vessel data
+- Displays agent badge on vessels from remote sources
+- Updates observer location from agent's GPS coordinates
+
+### Main Dashboard (`/`)
+- Agent selector in sidebar
+- Supports sensor, pager, WiFi, Bluetooth modes via agents
+- SDR conflict detection with device-aware warnings
+- Real-time sync with agent's running mode state
+
+### Multi-SDR Agent Support
+
+For agents with multiple SDR devices, the system now tracks which device each mode is using:
+
+```json
+{
+  "running_modes": ["sensor", "adsb"],
+  "running_modes_detail": {
+    "sensor": {"device": 0, "started_at": "2024-01-15T10:30:00Z"},
+    "adsb": {"device": 1, "started_at": "2024-01-15T10:35:00Z"}
+  }
+}
+```
+
+This allows:
+- Smart conflict detection (only warns if same device is in use)
+- Display of which device each mode is using
+- Parallel operation of multiple SDR modes on multi-SDR agents
+
+### Agent Mode Warnings
+
+When an agent has SDR modes running, the UI displays:
+- Warning banner showing active modes with device numbers
+- Stop buttons for each running mode
+- Refresh button to re-sync with agent state
+
+### Pages Without Agent Support
+
+The following pages don't require SDR-based agent support:
+- **Satellite Dashboard** (`/satellite/dashboard`) - Uses TLE orbital calculations, no SDR
+- **History pages** - Display stored data, not live SDR streams
