+# Bitcoin Seconds (BXS) - Start9 Deployment Guide
+
+## 🎯 Overview
+
+This guide covers the complete process of deploying Bitcoin Seconds as a Start9 service, from building the package to accessing the API on your Start9 device.
+
+## 📋 Prerequisites
+
+### Required
+- Docker installed and running
+- Node.js and npm installed
+- Start9 SDK: `npm install -g @start9labs/start-sdk`
+- Start9 device (for final deployment)
+
+### Optional
+- Bitcoin Core node (for real data mode)
+- Mempool.space service (for blockchain queries)
+
+## 🏗️ Build Process
+
+### Step 1: Build the Docker Image
+
+```bash
+cd /path/to/bxs-paper
+./start9/build.sh
+```
+
+This script will:
+- ✅ Check prerequisites (Docker, npm)
+- ✅ Build the Docker image (`bxs:0.1.0`)
+- ✅ Save image to tarball (118 MB)
+- ✅ Set script permissions
+- ✅ Create configuration template
+- ✅ Verify all package files
+
+**Expected Output:**
+```
+✓ Docker image built: bxs:0.1.0
+✓ Docker image saved: docker_images.tgz (118M)
+✓ All package files verified
+```
+
+### Step 2: Create the .s9pk Package
+
+```bash
+cd /path/to/bxs-paper
+start-sdk pack
+```
+
+This creates: `bitcoin-seconds.s9pk`
+
+**Note:** The first pack may take a few minutes as it validates all files and creates the package.
+
+## 📱 Installation on Start9
+
+### Via Web Interface
+
+1. **Navigate to Sideload**
+   - Open your Start9 web interface
+   - Go to **System** → **Sideload Service**
+
+2. **Upload Package**
+   - Click **Choose File**
+   - Select `bitcoin-seconds.s9pk`
+   - Click **Install**
+
+3. **Wait for Installation**
+   - Start9 will validate and install the package
+   - This may take 2-5 minutes
+
+4. **Configure Service**
+   - Navigate to **Services** → **Bitcoin Seconds**
+   - Click **Config**
+   - Adjust settings (defaults are good for testing)
+   - Click **Save**
+
+5. **Start Service**
+   - Click **Start**
+   - Wait for health check to pass (green status)
+
+### Via SSH (Advanced)
+
+```bash
+# Copy package to Start9
+scp bitcoin-seconds.s9pk start9@your-start9.local:/tmp/
+
+# SSH into Start9
+ssh start9@your-start9.local
+
+# Install package
+embassy-cli package install /tmp/bitcoin-seconds.s9pk
+
+# Start service
+embassy-cli service start bitcoin-seconds
+```
+
+## ⚙️ Configuration
+
+### Default Settings (Recommended for Testing)
+
+```yaml
+MOCK_MODE: true                    # Use synthetic data
+ALERT_DROP_PCT: 0.2                # Alert on 20% drop
+ALERT_WINDOW_DAYS: 14              # Monitor 14-day window
+T_MIN_SECS: 1000                   # SSR(t) floor for t: ~16 minutes
+MU_MIN_SATS_PER_S: 0.000001       # SSR(t) floor for μ(t): spend rate
+PIPELINE_INTERVAL_SECONDS: 600     # Update every 10 minutes
+```
+
+### Production Settings (With Bitcoin Node)
+
+```yaml
+MOCK_MODE: false                   # Use real Bitcoin data
+ALERT_DROP_PCT: 0.15               # More sensitive alerts
+ALERT_WINDOW_DAYS: 30              # Longer monitoring period
+T_MIN_SECS: 2592000                # 30 days minimum
+MU_MIN_SATS_PER_S: 0.00001        # Higher spend floor
+PIPELINE_INTERVAL_SECONDS: 300     # Update every 5 minutes
+```
+
+**Note:** Production mode requires Bitcoin Core and mempool.space services to be running and accessible.
+
+## 🔌 Accessing the Service
+
+### LAN Access
+
+```bash
+# Health check
+curl https://bitcoin-seconds.local/healthz
+
+# Latest metrics
+curl https://bitcoin-seconds.local/metrics/latest
+
+# Historical data
+curl "https://bitcoin-seconds.local/metrics/range?start=2024-01-01T00:00:00Z&end=2024-01-02T00:00:00Z"
+
+# Recent alerts
+curl https://bitcoin-seconds.local/alerts/recent?limit=5
+```
+
+### Tor Access
+
+1. Find your Tor address in Start9 interface:
+   - Services → Bitcoin Seconds → Interfaces → Tor Address
+
+2. Use with Tor browser or `torify`:
+   ```bash
+   torify curl http://[your-onion-address].onion/healthz
+   ```
+
+### API Documentation
+
+Once running, access interactive API docs at:
+- **LAN**: `https://bitcoin-seconds.local/docs`
+- **Tor**: `http://[your-onion-address].onion/docs`
+
+## 📊 Using the API
+
+### Example: Monitor Your Bitcoin Position
+
+```bash
+#!/bin/bash
+# get-bxs-status.sh
+
+API_URL="https://bitcoin-seconds.local"
+
+# Get latest metrics
+METRICS=$(curl -s "$API_URL/metrics/latest")
+
+# Extract key values (requires jq)
+BALANCE=$(echo "$METRICS" | jq -r '.balance_sats')
+FLOW=$(echo "$METRICS" | jq -r '.flow_rate')
+BXS=$(echo "$METRICS" | jq -r '.bxs_persistence')
+
+echo "Bitcoin Seconds Status"
+echo "====================="
+echo "Balance: $(($BALANCE / 100000000)) BTC"
+echo "Flow Rate: $FLOW sats/s"
+echo "BXS Persistence: $BXS sats·s"
+
+# Check for alerts
+ALERTS=$(curl -s "$API_URL/alerts/recent?limit=1")
+if [ "$(echo "$ALERTS" | jq 'length')" -gt 0 ]; then
+    echo "⚠️  Alert: $(echo "$ALERTS" | jq -r '.[0].message')"
+fi
+```
+
+### Example: Dashboard Integration
+
+```python
+import requests
+import time
+
+API_URL = "https://bitcoin-seconds.local"
+
+def get_bxs_metrics():
+    """Fetch latest BXS metrics."""
+    response = requests.get(f"{API_URL}/metrics/latest")
+    return response.json()
+
+def monitor_durability():
+    """Continuous monitoring of durability flow."""
+    while True:
+        metrics = get_bxs_metrics()
+        
+        print(f"Timestamp: {metrics['timestamp']}")
+        print(f"Flow Rate: {metrics['flow_rate']:.6f} sats/s")
+        print(f"Stock: {metrics['cumulative_stock']:,.0f} sats")
+        print(f"BXS: {metrics['bxs_persistence']:,.0f} sats·s")
+        print("-" * 50)
+        
+        time.sleep(600)  # Check every 10 minutes
+
+if __name__ == "__main__":
+    monitor_durability()
+```
+
+## 🔍 Monitoring & Troubleshooting
+
+### View Logs
+
+**In Start9 Interface:**
+- Services → Bitcoin Seconds → Logs
+
+**Via SSH:**
+```bash
+embassy-cli service logs bitcoin-seconds
+```
+
+### Health Check
+
+```bash
+# Should return: {"status": "ok"}
+curl https://bitcoin-seconds.local/healthz
+```
+
+If unhealthy:
+1. Check service logs for errors
+2. Verify configuration (especially mock mode in testing)
+3. Restart service: Services → Bitcoin Seconds → Restart
+4. Check system resources (CPU, memory, disk)
+
+### Common Issues
+
+#### Service Won't Start
+- **Cause**: Configuration error or insufficient resources
+- **Solution**: 
+  - Check logs for specific error
+  - Verify all required config fields are set
+  - Enable mock mode for testing
+
+#### API Not Responding
+- **Cause**: Service not fully started or network issue
+- **Solution**:
+  - Wait 30-60 seconds after start
+  - Check health status in Start9 UI
+  - Verify network connectivity
+
+#### No Metrics Data
+- **In Mock Mode**: Should never happen - check logs
+- **In Real Mode**: 
+  - Verify Bitcoin Core is synced
+  - Check RPC credentials
+  - Wait for first pipeline run (10 minutes default)
+
+#### High Resource Usage
+- **Cause**: Too frequent pipeline updates
+- **Solution**: Increase `PIPELINE_INTERVAL_SECONDS` to 900 or 1800
+
+## 🔄 Updating the Service
+
+### Process
+
+1. **Build new version**
+   ```bash
+   git pull
+   ./start9/build.sh
+   embassy-sdk pack start9
+   ```
+
+2. **Upload to Start9**
+   - System → Sideload Service
+   - Upload new `bitcoin-seconds.s9pk`
+
+3. **Start9 handles migration**
+   - Stops old version
+   - Migrates data
+   - Starts new version
+
+4. **Verify update**
+   ```bash
+   curl https://bitcoin-seconds.local/healthz
+   ```
+
+### Data Preservation
+
+Start9 automatically preserves:
+- SQLite database (all historical metrics)
+- Configuration settings
+- Alert history
+
+## 💾 Backup & Restore
+
+### Automatic Backup
+
+Start9 includes BXS data in system backups:
+- Services → Bitcoin Seconds → Create Backup
+
+### Manual Export
+
+```bash
+# Via SSH
+scp start9@your-start9.local:/embassy/volumes/bitcoin-seconds/data/bxs.sqlite ./backup/
+
+# Via API (if admin enabled)
+curl https://bitcoin-seconds.local/admin/export > bxs-backup.json
+```
+
+### Restore
+
+1. Stop service
+2. Replace database file
+3. Restart service
+
+## 🧪 Local Development & Testing
+
+### Test Before Deploying
+
+```bash
+# Start service locally
+docker-compose -f start9/docker-compose.yml up -d
+
+# Run tests
+curl http://localhost:8080/healthz
+curl http://localhost:8080/metrics/latest
+
+# Check logs
+docker-compose -f start9/docker-compose.yml logs -f
+
+# Stop when done
+docker-compose -f start9/docker-compose.yml down
+```
+
+### Modify and Rebuild
+
+```bash
+# Make code changes
+vim code/app/main.py
+
+# Rebuild
+./start9/build.sh
+
+# Test locally
+docker-compose -f start9/docker-compose.yml up --build -d
+```

+# Icons Changelog
+
+## 2025-11-06 - Initial Icon Structure
+
+### Created Structure
+
+Organized icons into a professional directory structure with subdirectories for different use cases:
+
+- **Main icons** (`/icons`): Multiple sizes from 64px to 1024px
+- **Web assets** (`/icons/web`): Favicons and PWA manifest
+- **Start9 package** (`/icons/start9`): Icon for Start9 deployment
+- **Social media** (`/icons/social`): Open Graph and square images
+
+### Source Files
+
+- `bxs-emblem.svg` - Vector source (1024x1024)
+- `bxs003.png` - Photo source (1800x1800)
+
+### Generated Assets
+
+#### Main Icons (in `/icons`)
+- `bxs-1024.png` - Highest resolution for app stores
+- `bxs-512.png` - Standard high-res icon
+- `bxs-256.png` - Desktop application icon
+- `bxs-192.png` - PWA icon size
+- `bxs-128.png` - Medium UI elements
+- `bxs-64.png` - Small UI elements
+
+#### Monochrome Variants (in `/icons`)
+- `bxs-512-mono-dark.png` - For light themes
+- `bxs-512-mono-light.png` - For dark themes
+
+#### Web Assets (in `/icons/web`)
+- `favicon-32.png` - Standard favicon
+- `favicon-16.png` - Small favicon
+- `favicon.ico` - Multi-size ICO (16, 32, 48)
+- `site.webmanifest` - PWA manifest with theme colors
+
+#### Start9 Package (in `/icons/start9`)
+- `icon.png` - 512x512 icon for Start9 manifest
+
+#### Social Media (in `/icons/social`)
+- `og-1200x630.png` - Open Graph / Twitter card
+- `square-1080.png` - Square social sharing (Instagram, etc.)
+
+### Tools Created
+
+- `../tools/generate_icons.py` - Automated icon generation script
+  - Handles SVG to PNG conversion (with cairosvg or ImageMagick)
+  - Falls back to PNG resizing if SVG tools unavailable
+  - Generates all sizes and variants
+  - Creates favicons and web manifest
+  - Generates social media images with branded backgrounds
+
+### Documentation
+
+- `README.md` - Complete documentation with:
+  - Directory structure overview
+  - Design elements and color palette
+  - Usage guidelines for web, Start9, and apps
+  - Size reference table
+  - Regeneration instructions
+
+### Integration
+
+Updated main project `README.md` to reference the icons directory in the repository layout section.
+
+### Color Palette Used
+
+- Navy: `#0B1E36` (backgrounds, theme color)
+- Orange: `#F7931A` (Bitcoin logo, accents)
+- Off-white: `#FAF7F2` (text, light elements, PWA background)
+- Gold: `#FFC24A` (orbital accents)
+
+### Regeneration
+
+All derived assets can be regenerated with:
+```bash
+python3 tools/generate_icons.py
+```
+
+This ensures reproducibility and makes it easy to update all sizes if the source images change.

+## Component Details
+
+### 1. FastAPI Web Server
+
+**Purpose**: REST API for querying BXS metrics
+
+**Technology**: 
+- FastAPI (Python web framework)
+- Uvicorn (ASGI server)
+- Pydantic (data validation)
+
+**Endpoints**:
+- `GET /healthz` - Health check (returns 200 if healthy)
+- `GET /metrics/latest` - Latest computed metrics
+- `GET /metrics/range` - Historical data in time range
+- `GET /alerts/recent` - Recent alert history
+- `GET /docs` - Interactive API documentation
+
+**Port**: 8080 (internal), proxied via Start9
+
+### 2. Data Pipeline Runner
+
+**Purpose**: Periodic data collection and metric computation
+
+**Process**:
+1. **Data Collection**
+   - Mock mode: Generate synthetic data
+   - Real mode: Query Bitcoin Core RPC + mempool.space API
+   
+2. **Metric Computation**
+   - Calculate coin age `A(t)` [s]
+   - Determine income/spend rates `i(t)`, `μ(t)` [sats/s]
+   - Compute SSR (Surplus-to-Spending Ratio)
+   - Calculate flow `f(t)` [sats/s], stock `S(t)` [sats], persistence `BXS(t)` [sats·s]
+
+3. **Alert Evaluation**
+   - Compare current flow to historical baseline
+   - Trigger alerts on significant drops
+   - Store alert events
+
+4. **Data Storage**
+   - Insert metrics into SQLite
+   - Maintain historical time series
+
+**Interval**: Configurable (default: 600 seconds / 10 minutes)
+
+**Run Mode**: Background process, runs continuously
+
+### 3. SQLite Database
+
+**Purpose**: Persistent storage for all historical data
+
+**Location**: `/app/data/bxs.sqlite` (in persistent volume)
+
+**Schema**:
+
+```sql
+-- Historical metrics
+CREATE TABLE metrics (
+    timestamp INTEGER PRIMARY KEY,
+    balance_sats INTEGER,
+    coin_age_seconds INTEGER,
+    flow_rate REAL,
+    cumulative_stock INTEGER,
+    bxs_persistence INTEGER,
+    ssr REAL
+);
+
+-- Alert history
+CREATE TABLE alerts (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    timestamp INTEGER,
+    alert_type TEXT,
+    message TEXT,
+    severity TEXT,
+    metadata TEXT
+);
+
+-- Runtime configuration
+CREATE TABLE config (
+    key TEXT PRIMARY KEY,
+    value TEXT,
+    updated_at INTEGER
+);
+```
+
+**Backup**: Included in Start9's automatic backup system
+
+## Data Flow
+
+### Typical Operation Cycle
+
+```
+1. Pipeline Wake Up (every 10 minutes)
+        ↓
+2. Fetch Data
+   ├─ Mock Mode: Generate synthetic UTXO data
+   └─ Real Mode: Query Bitcoin Core + mempool.space
+        ↓
+3. Compute Metrics
+   ├─ Calculate A(t) (coin age) [s]
+   ├─ Calculate I(t) (expansion rate) [s⁻¹]
+   ├─ Calculate SSR(t) (surplus-to-spending ratio)
+   ├─ Compute f(t) = i(t) × (A(t)/A₀) × (I(t)/I₀) × SSR(t) [sats/s]
+   ├─ Update S(t) = ∫f(t)dt [sats]
+   └─ Update BXS(t) = ∫S(t)dt [sats·s]
+        ↓
+4. Check Alerts
+   ├─ Compare f(t) to baseline
+   ├─ Detect drops > threshold
+   └─ Generate alert if triggered
+        ↓
+5. Store to Database
+   ├─ INSERT INTO metrics
+   └─ INSERT INTO alerts (if any)
+        ↓
+6. Sleep until next interval
+```
+
+### API Request Flow
+
+```
+Client Request
+    ↓
+Start9 Proxy (LAN/Tor)
+    ↓
+FastAPI Server (port 8080)
+    ↓
+SQLite Query

+Format Response (JSON)
+    ↓
+Return to Client
+```
+
+## Configuration System
+
+### Configuration Sources
+
+1. **Start9 UI**
+   - User edits in web interface
+   - Calls `set-config.sh`
+   - Updates `/app/.env`
+
+2. **Environment Variables**
+   - Loaded from `/app/.env`
+   - Available to all processes
+   - Persist across restarts
+
+3. **Runtime Properties**
+   - Read via `properties.sh`
+   - Displayed in Start9 UI
+   - Includes computed values
+
+### Configuration Flow
+
+```
+Start9 UI (User Input)
+    ↓
+set-config.sh (validation)
+    ↓
+/app/.env (file write)
+    ↓
+Container Restart (if needed)
+    ↓
+Environment Variables (loaded)
+    ↓
+Application Config (applied)
+```
+
+## Health Check System
+
+### Health Check Process
+
+```
+Start9 Scheduler (every 30s)
+    ↓
+check-web.sh (runs in container)
+    ↓
+HTTP GET localhost:8080/healthz
+    ↓
+API Health Check Handler
+    ├─ Check database connection
+    ├─ Check pipeline status
+    └─ Verify last update time
+    ↓
+Return JSON Status
+    ↓
+Start9 UI (display green/red)
+```
+
+### Health Criteria
+
+- ✅ **Healthy**: API responds with 200, database accessible
+- ⚠️ **Degraded**: API responds but stale data (>30 min old)
+- ❌ **Unhealthy**: API not responding or database error
+
+## Network Architecture
+
+### LAN Access
+
+```
+Client (https://bitcoin-seconds.local:443)
+    ↓
+Start9 Reverse Proxy (nginx)
+    ├─ SSL termination
+    ├─ Authentication (if enabled)
+    └─ Forward to container:8080
+    ↓
+BXS API Server
+```
+
+### Tor Access
+
+```
+Client (http://[onion].onion:80)
+    ↓
+Tor Hidden Service
+    ↓
+Start9 Tor Proxy
+    └─ Forward to container:8080
+    ↓
+BXS API Server
+```
+
+## Security Layers
+
+### 1. Container Isolation
+- Runs in separate Docker container
+- Limited system access
+- Controlled resource allocation
+
+### 2. Network Segmentation
+- No direct external network access (mock mode)
+- Only local container network in real mode
+- All external access via Start9 proxy
+
+### 3. Data Encryption
+- Volume encrypted by Start9
+- TLS for LAN access (Start9 handles)
+- Tor encryption for .onion access
+
+### 4. Access Control
+- Start9 authentication required
+- Optional API key (future)
+- Rate limiting via Start9
+
+## Performance Characteristics
+
+### Resource Usage
+
+**CPU**:
+- Idle: <1% (waiting for next pipeline run)
+- Active: 5-10% (during 10-second computation burst)
+- Peak: 20% (initial database setup)
+
+**Memory**:
+- Base: 150 MB (Python + FastAPI)
+- Working: 200 MB (during computation)
+- Peak: 256 MB (with large queries)
+
+**Disk**:
+- Initial: 150 MB (Docker image + empty database)
+- Growth: ~10 MB/year (depends on update frequency)
+- Max: 500 MB (with several years of data)
+
+**Network** (Real Mode):
+- Per Update: <100 KB (RPC calls + API queries)
+- Daily: <5 MB (at 10-minute intervals)
+- Monthly: <150 MB
+
+### Scalability
+
+**Current Limits**:
+- Single wallet support
+- 10-minute minimum update interval
+- ~10 years of data before optimization needed
+- API rate limited by Start9
+
+**Future Improvements**:
+- Multi-wallet support
+- Faster update intervals (1-5 minutes)
+- Database partitioning for larger datasets
+- Caching layer for frequent queries

+# Connecting Bitcoin Seconds to Real Bitcoin Data
+
+This guide explains how to configure Bitcoin Seconds to use real data from your Bitcoin Core node and mempool.space service instead of mock data.
+
+## Prerequisites
+
+Before connecting to real data, ensure you have:
+
+1. **Bitcoin Core** running on your Start9 device
+   - Fully synced blockchain
+   - RPC enabled
+   - Wallet loaded (if tracking your own wallet)
+
+2. **Mempool.space** service running on Start9
+   - Accessible via local network
+   - API endpoints working
+
+## Configuration Methods
+
+### Method 1: Start9 UI Configuration (Recommended - No SSH Required!)
+
+**This is the easiest way!** Configure everything through the Start9 web interface using dependency pointers:
+
+1. **Install Dependencies** (if not already installed):
+   - Go to **Services** → **Marketplace** in Start9 UI
+   - Search for and install **Bitcoin Core** (or **Bitcoin Knots**)
+   - Search for and install **Mempool.space**
+   - Wait for both services to be fully synced and running
+
+2. **Configure Bitcoin Seconds**:
+   - Go to **Services** → **Bitcoin Seconds** → **Configure**
+   - Set **Mock Mode** to `false` (toggle off)
+   - The following fields will **automatically populate** from your dependencies:
+     - **Bitcoin RPC Username** (from Bitcoin Core/Knots)
+     - **Bitcoin RPC Password** (from Bitcoin Core/Knots)
+     - **Mempool API URL** (from Mempool service)
+   - Adjust other settings as needed:
+     - **Alert Drop Percentage** (default: 20%)
+     - **Alert Window** (default: 14 days)
+     - **Pipeline Interval** (default: 600 seconds)
+   - Click **Save**
+
+3. **Verify Dependencies are Connected**:
+   - In the configuration screen, check that the dependency fields show values
+   - If fields are empty, go to the **Dependencies** section and ensure Bitcoin Core/Knots and Mempool are selected
+
+4. **Start/Restart the Service**:
+   - The service will automatically restart after saving configuration
+   - Go to **Services** → **Bitcoin Seconds** → **Logs**
+   - Look for: "Fetching block data from mempool.space..."
+   - Look for: "Fetching wallet data from Bitcoin RPC..."
+   - Should NOT see: "Using mock data"
+
+**That's it!** No SSH or manual file editing required.
+
+### Method 2: SSH Configuration (Fallback)
+
+1. **SSH into your Start9 device:**
+   ```bash
+   ssh start9@your-start9.local
+   ```
+
+2. **Navigate to the service directory:**
+   ```bash
+   cd /embassy-data/package-data/volumes/bitcoin-seconds
+   ```
+
+3. **Create or edit the `.env` file:**
+   ```bash
+   sudo nano .env
+   ```
+
+4. **Add the following configuration:**
+   ```bash
+   # Disable mock mode
+   MOCK_MODE=false
+
+   # Bitcoin Core RPC Configuration
+   BITCOIN_RPC_URL=http://bitcoin-core.embassy:8332
+   BITCOIN_RPC_USER=your_rpc_username
+   BITCOIN_RPC_PASSWORD=your_rpc_password
+
+   # Mempool.space API (local Start9 instance)
+   MEMPOOL_API_URL=https://mempool.local
+
+   # Pipeline settings
+   PIPELINE_INTERVAL_SECONDS=600
+
+   # Alert settings
+   ALERT_DROP_PCT=0.2
+   ALERT_WINDOW_DAYS=14
+   T_MIN_SECS=1000
+   MU_MIN_SATS_PER_S=0.000001
+   ```
+
+5. **Get Bitcoin Core RPC credentials:**
+   
+   If Bitcoin Core is running as a Start9 service:
+   - Go to Start9 UI → Services → Bitcoin Core
+   - Check the service details for RPC connection info
+   - The RPC URL is typically: `http://bitcoin-core.embassy:8332`
+   - Username and password are in the service configuration
+
+6. **Restart the Bitcoin Seconds service:**
+   ```bash
+   # From Start9 UI: Services → Bitcoin Seconds → Restart
+   # Or via CLI:
+   embassy-cli service restart bitcoin-seconds
+   ```
+
+### Method 3: Manual Configuration via SSH (Advanced)
+
+If the UI configuration doesn't work or you need to override values, you can manually edit the `.env` file:
+
+## Finding Your Bitcoin Core RPC Settings
+
+### If Bitcoin Core is a Start9 Service:
+
+1. Open Start9 web interface
+2. Navigate to **Services** → **Bitcoin Core**
+3. Look for **Connection Info** or **RPC Settings**
+4. Note the:
+   - RPC URL (usually `http://bitcoin-core.embassy:8332`)
+   - RPC Username
+   - RPC Password
+
+### If Bitcoin Core is Running Elsewhere:
+
+1. Check your `bitcoin.conf` file:
+   ```conf
+   server=1
+   rpcuser=your_username
+   rpcpassword=your_password
+   rpcallowip=127.0.0.1
+   rpcport=8332
+   ```
+
+2. Test the connection:
+   ```bash
+   curl --user your_username:your_password \
+        --data-binary '{"jsonrpc":"1.0","id":"test","method":"getblockchaininfo","params":[]}' \
+        http://your-bitcoin-node:8332
+   ```
+
+## Finding Your Mempool.space URL
+
+### If Mempool.space is a Start9 Service:
+
+1. Open Start9 web interface
+2. Navigate to **Services** → **Mempool.space**
+3. Check the **Interfaces** section
+4. Use the LAN URL (e.g., `https://mempool.local`)
+
+### If Mempool.space is Running Elsewhere:
+
+- Use the full URL: `https://your-mempool-instance.local`
+- Or public instance: `https://mempool.space` (not recommended for privacy)
+
+## Verifying the Connection
+
+After configuring, verify everything works:
+
+1. **Check service logs:**
+   ```bash
+   # In Start9 UI: Services → Bitcoin Seconds → Logs
+   # Or via SSH:
+   docker logs bitcoin-seconds.embassy
+   ```
+
+2. **Look for successful data fetches:**
+   ```
+   Fetching block data from mempool.space...
+   Fetching wallet data from Bitcoin RPC...
+   Pipeline step completed successfully
+   ```
+
+3. **Check the API:**
+   ```bash
+   curl https://bitcoin-seconds.local/metrics/latest
+   ```
+
+   You should see real data instead of mock values.
+
+## Troubleshooting
+
+### "Connection refused" to Bitcoin RPC
+
+**Problem:** Can't connect to Bitcoin Core RPC
+
+**Solutions:**
+- Verify Bitcoin Core service is running
+- Check RPC URL is correct (use service name: `bitcoin-core.embassy`)
+- Verify RPC credentials match Bitcoin Core config
+- Check if RPC is enabled in Bitcoin Core (`server=1` in bitcoin.conf)
+- Ensure Bitcoin Core allows connections from the Bitcoin Seconds container
+
+### "Cannot access mempool.space API"
+
+**Problem:** Mempool.space API calls failing
+
+**Solutions:**
+- Verify mempool.space service is running
+- Check the URL is correct (try `https://mempool.local`)
+- Test manually: `curl https://mempool.local/api/blocks`
+- If using public instance, ensure network connectivity
+
+### "No wallet data" or "Balance is 0"
+
+**Problem:** Wallet RPC calls succeed but return empty data
+
+**Solutions:**
+- Ensure Bitcoin Core has a wallet loaded
+- Check wallet is not encrypted (or unlock it)
+- Verify wallet has transactions/UTXOs
+- If tracking a specific wallet, ensure it's loaded in Bitcoin Core
+
+### Pipeline Still Using Mock Data
+
+**Problem:** Even after setting `MOCK_MODE=false`, still seeing mock data
+
+**Solutions:**
+- Verify `.env` file is in the correct location
+- Check environment variable is actually `false` (not `"false"` or `False`)
+- Restart the service after changing `.env`
+- Check logs for "MOCK_MODE" to see what value is being used
+- Ensure `.env` file is readable by the container
+
+## Advanced Configuration
+
+### Custom RPC Endpoint
+
+If Bitcoin Core is on a different machine:
+
+```bash
+BITCOIN_RPC_URL=http://192.168.1.100:8332
+```
+
+### Custom Mempool Instance
+
+If using a different mempool instance:
+
+```bash
+MEMPOOL_API_URL=https://your-custom-mempool.local
+```
+
+### Faster Updates
+
+To update more frequently (uses more resources):
+
+```bash
+PIPELINE_INTERVAL_SECONDS=300  # Every 5 minutes instead of 10
+```
+
+### More Sensitive Alerts
+
+To get alerts for smaller changes:
+
+```bash
+ALERT_DROP_PCT=0.15  # Alert on 15% drop instead of 20%
+ALERT_WINDOW_DAYS=30  # Monitor 30 days instead of 14
+```
+
+## Security Considerations
+
+⚠️ **Important Security Notes:**
+
+1. **RPC Credentials**: Never commit `.env` file with real credentials
+2. **Network Access**: Keep RPC access restricted to local network
+3. **Wallet Security**: If tracking your own wallet, ensure Bitcoin Core wallet is properly secured
+4. **HTTPS**: Use HTTPS for mempool.space when possible
+5. **Tor**: Consider accessing the API over Tor for additional privacy
+
+## Next Steps
+
+Once connected to real data:
+
+1. **Monitor the dashboard** to see real-time metrics
+2. **Set up alerts** for important threshold changes
+3. **Review historical data** via the API
+4. **Integrate with other tools** using the REST API
+
+## Support
+
+If you encounter issues:
+
+1. Check the service logs for detailed error messages
+2. Verify all prerequisites are met
+3. Test each component individually (Bitcoin RPC, mempool API)
+4. Open an issue on GitHub with:
+   - Error messages from logs
+   - Your configuration (with credentials redacted)
+   - Steps to reproduce
+

+
+**Happy tracking! 🚀**

+IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and

+    work, arrangement of music or other alterations of a literary or artistic
+    work, or phonogram or performance and includes cinematographic adaptations
+    or any other form in which the Work may be recast, transformed, or adapted
+    including in any form recognizably derived from the original, except that a
+    work that constitutes a Collection will not be considered an Adaptation for
+    the purpose of this License. For the avoidance of doubt, where the Work is
+    a musical work, performance or phonogram, the synchronization of the Work

+    encyclopedias and anthologies, or performances, phonograms or broadcasts,
+    or other works or subject matter other than works listed in Section 1(f)
+    below, which, by reason of the selection and arrangement of their
+    contents, constitute intellectual creations, in which the Work is included
+    in its entirety in unmodified form along with one or more other
+    contributions, each constituting separate and independent works in
+    themselves, which together are assembled into a collective whole. A work
+    that constitutes a Collection will not be considered an Adaptation (as
+    defined above) for the purposes of this License.
+
+ c. "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or other
+    transfer of ownership.
+
+ d. "Licensor" means the individual, individuals, entity or entities that
+    offer(s) the Work under the terms of this License.
+
+ e. "Original Author" means, in the case of a literary or artistic work, the
+    individual, individuals, entity or entities who created the Work or if no
+    individual or entity can be identified, the publisher; and in addition (i)

+    other persons who act, sing, deliver, declaim, play in, interpret or
+    otherwise perform literary or artistic works or expressions of folklore;
+    (ii) in the case of a phonogram the producer being the person or legal
+    entity who first fixes the sounds of a performance or other sounds; and,
+    (iii) in the case of broadcasts, the organization that transmits the
+    broadcast.
+
+ f. "Work" means the literary and/or artistic work offered under the terms of

+    writing; a lecture, address, sermon or other work of the same nature; a
+    dramatic or dramatico-musical work; a choreographic work or entertainment
+    in dumb show; a musical composition with or without words; a
+    cinematographic work to which are assimilated works expressed by a process
+    analogous to cinematography; a work of drawing, painting, architecture,
+    sculpture, engraving or lithography; a photographic work to which are
+    assimilated works expressed by a process analogous to photography; a work
+    of applied art; an illustration, map, plan, sketch or three-dimensional
+    work relative to geography, topography, architecture or science; a

+    it is protected as a copyrightable work; or a work performed by a variety
+    or circus performer to the extent not susceptible to being fixed in a
+    cinematographic or audiovisual work.
+
+ g. "You" means an individual or entity exercising rights under this License
+    who has not previously violated the terms of this License with respect to
+    the Work, or who has received express permission from the Licensor to
+    exercise rights under this License despite a previous violation.
+
+ h. "Publicly Perform" means to perform public recitations of the Work and to
+    communicate to the public those public recitations, by any means or process,
+    including by wire or wireless means or public digital performances; to
+    make available to the public Works in such a way that members of the public
+    may access these Works from a place and at a place individually chosen by
+    them; to perform the Work to the public by any means or process and the
+    communication to the public of the performances of the Work, including by

+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce, limit,
+   or restrict any uses free from copyright or rights arising from
+   limitations or exceptions that are provided for in connection with the
+   copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+   Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+   perpetual (for the duration of the applicable copyright) license to
+   exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the Collections;
+
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made to
+    the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a modification
+    could indicate "The original work has been modified.";
+
+ c. to Distribute and Publicly Perform the Work including as incorporated in
+    Collections; and,
+
+ d. to Distribute and Publicly Perform Adaptations.
+
+ The above rights may be exercised in all media and formats whether now known
+ or hereafter devised. The above rights include the right to make such
+ modifications as are technically necessary to exercise the rights in other
+ media and formats. Subject to Section 8(f), all rights not expressly granted
+ by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+   subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms of
+    this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms on
+    the Work that restrict the terms of this License or the ability of the
+    recipient of the Work to exercise the rights granted to that recipient
+    under the terms of the License. You may not sublicense the Work. You must
+    keep intact all notices that refer to this License and to the disclaimer of
+    warranties with every copy of the Work You Distribute or Publicly Perform.
+    When You Distribute or Publicly Perform the Work, You may not impose any
+    effective technological measures on the Work that restrict the ability of a
+    recipient of the Work from You to exercise the rights granted to that
+    recipient under the terms of the License. This Section 4(a) applies to the
+    Work as incorporated in a Collection, but this does not require the
+    Collection apart from the Work itself to be made subject to the terms of
+    this License. If You create a Collection, upon notice from any Licensor You
+    must, to the extent practicable, remove from the Collection any credit as
+    required by Section 4(c), as requested. If You create an Adaptation, upon
+    notice from any Licensor You must, to the extent practicable, remove from
+    the Adaptation any credit as required by Section 4(c), as requested.
+
+ b. You may not exercise any of the rights granted to You in Section 3 above
+    in any manner that is primarily intended for or directed toward commercial
+    advantage or private monetary compensation. The exchange of the Work for
+    other copyrighted works by means of digital file-sharing or otherwise shall
+    not be considered to be intended for or directed toward commercial
+    advantage or private monetary compensation, provided there is no payment of
+    any monetary compensation in con-nection with the exchange of copyrighted
+    works.
+
+ c. If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to Section
+    4(a), keep intact all copyright notices for the Work and provide, in
+    reasonable and prominent manner, the name of the Original Author (or
+    pseudonym, if applicable) if supplied, and/or if the Original Author
+    and/or Licensor designate another party or parties (e.g., a sponsor
+    institute, publishing entity, journal) for attribution ("Attribution
+    Parties") in Licensor's copyright notice, terms of service or by other
+    reasonable means, the name of such party or parties; the title of the Work
+    if supplied; to the extent reasonably practicable, the URI, if any, that
+    Licensor specifies to be associated with the Work, unless such URI does
+    not refer to the copyright notice or licensing information for the Work;
+    and in the case of an Adaptation, a credit identifying the use of the Work
+    in the Adaptation (e.g., "French translation of the Work by Original
+    Author," or "Screenplay based on original Work by Original Author"). The
+    credit required by this Section 4(c) may be implemented in any reasonable
+    manner; provided, however, that in the case of an Adaptation or
+    Collection, at a minimum such credit will appear, if a credit for all
+    contributing authors of the Adaptation or Collection appears, then as part
+    of these credits and in a manner at least as prominent as the credits for
+    the other contributing authors. For the avoidance of doubt, You may only
+    use the credit required by this Section for the purpose of attribution in
+    the manner set out above and, by exercising Your rights under this
+    License, You may not implicitly or explicitly assert or imply any
+    connection with, sponsorship or endorsement by the Original Author,
+    Licensor and/or Attribution Parties, as appropriate, of You or Your use
+    of the Work, without the separate, express prior written permission of
+    the Original Author, Licensor and/or Attribution Parties.
+
+ d. For the avoidance of doubt:
+
+    i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+       which the right to collect royalties through any statutory or compulsory
+       licensing scheme cannot be waived, the Licensor reserves the exclusive
+       right to collect such royalties for any exercise by You of the rights
+       granted under this License;
+
+   ii. Waivable Compulsory License Schemes. In those jurisdictions in which
+       the right to collect royalties through any statutory or compulsory
+       licensing scheme can be waived, the Licensor waives the exclusive right
+       to collect such royalties for any exercise by You of the rights granted
+       under this License; and,
+
+  iii. Voluntary License Schemes. The Licensor waives the right to collect
+       royalties, whether individually or, in the event that the Licensor is a
+       member of a collecting society that administers voluntary licensing
+       schemes, via that society, from any exercise by You of the rights
+       granted under this License.
+
+ The above rights may be exercised in all media and formats whether now known
+ or hereafter devised. The above rights include the right to make such
+ modifications as are technically necessary to exercise the rights in other
+ media and formats. Subject to Section 8(f), all rights not expressly granted
+ by Licensor are hereby reserved.
+
+5. Representations, Warranties and Disclaimer
+
+ UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+ OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND
+ CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING,
+ WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A
+ PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER
+ DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT
+ DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED
+ WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW,
+   IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY
+   SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING
+   OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN
+   ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate automatically
+    upon any breach by You of the terms of this License. Individuals or
+    entities who have received Adaptations or Collections from You under this
+    License, however, will not have their licenses terminated provided such
+    individuals or entities remain in full compliance with those licenses.
+    Sections 1, 2, 5, 6, 7, and 8 will survive any termination of this
+    License.
+
+ b. Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the Work
+    under different license terms or to stop distributing the Work at any time;
+    provided, however that any such election will not serve to withdraw this
+    License (or any other license that has been, or is required to be, granted
+    under the terms of this License), and this License will continue in full
+    force and effect unless terminated as stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection, the
+    Licensor offers to the recipient a license to the Work on the same terms
+    and conditions as the license granted to You under this License.
+
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same terms
+    and conditions as the license granted to You under this License.
+
+ c. If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of the
+    remainder of the terms of this License, and without further action by the
+    parties to this agreement, such provision shall be reformed to the
+    minimum extent necessary to make such provision valid and enforceable.
+
+ d. No term or provision of this License shall be deemed waived and no breach
+    consented to unless such waiver or consent shall be in writing and signed
+    by the party to be charged with such waiver or consent.
+
+ e. This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings, agreements
+    or representations with respect to the Work not specified here. Licensor
+    shall not be bound by any additional provisions that may appear in any
+    communication from You. This License may not be modified without the
+    mutual written agreement of the Licensor and You.
+
+ f. The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention for
+    the Protection of Literary and Artistic Works (as amended on September 28,
+    1979), the Rome Convention of 1961, the WIPO Copyright Treaty of 1996, the
+    WIPO Performances and Phonograms Treaty of 1996 and the Universal Copyright
+    Convention (as revised on July 24, 1971). These rights and subject matter
+    take effect in the relevant jurisdiction in which the License terms are
+    sought to be enforced according to the corresponding provisions of the
+    implementation of those treaty provisions in the applicable national law.
+    If the standard suite of rights granted under applicable copyright law
+    includes additional rights not granted under this License, such additional
+    rights are deemed to be included in the License; this License is not
+    intended to restrict the license of any rights under applicable law.
+
+Creative Commons is not a party to this License, and makes no warranty
+whatsoever in connection with the Work. Creative Commons will not be liable to
+You or any party on any legal theory for any damages whatsoever, including
+without limitation any general, special, incidental or consequential damages
+arising in connection to this license. Notwithstanding the foregoing two (2)
+sentences, Creative Commons may elect to apply one of its public licenses to
+material submitted to it, and in such case, Creative Commons becomes a
+Licensor with the same rights and obligations as stated herein.
+
+Except for the limited purpose of indicating to the public that the Work is

+## 🚀 Deployment Steps
+
+### Step 1: Verify Build
+
+```bash
+✓ Docker image built: bxs:0.1.0
+✓ Docker image saved: docker_images.tgz (118M)
+✓ All package files verified
+```
+
+### Step 2: Install Start9 SDK (One-Time)
+
+```bash
+npm install -g @start9labs/start-sdk
+```
+
+### Step 3: Create .s9pk Package
+
+```bash
+cd /Users/<User>/<Path>/bxs-paper
+start-sdk pack
+```
+
+This will create: `bitcoin-seconds.s9pk`
+
+### Step 4: Install on Start9
+
+1. Open Start9 web interface
+2. Navigate to **System** → **Sideload Service**
+3. Upload `bitcoin-seconds.s9pk`
+4. Click **Install**
+5. Configure settings (default: mock mode enabled)
+6. Click **Start**
+
+### Step 5: Verify Installation
+
+```bash
+# Via LAN
+curl https://bitcoin-seconds.local/healthz
+
+# Expected response: {"status": "ok"}
+```
+
+## 🧪 Testing Without Start9
+
+You can test the package locally before deploying:
+
+```bash
+# Start service
+docker-compose -f start9/docker-compose.yml up -d
+
+# Test health
+curl http://localhost:8080/healthz
+
+# Get latest metrics
+curl http://localhost:8080/metrics/latest
+
+# View logs
+docker-compose -f start9/docker-compose.yml logs -f
+
+# Stop service
+docker-compose -f start9/docker-compose.yml down
+```

+# BXS Service Polish Summary
+
+## ✅ Completed (Ready for Ship)
+
+### API & Data Contract
+- ✅ **API Contract Updated**: `/metrics/latest` returns ISO8601 timestamps, block height `h`, `S_cum`, `BXS_cum`, and `ready` status
+- ✅ **503 Response**: Returns `{"ready": false}` during warm-up
+- ✅ **Range Endpoint**: Supports `step` parameter (block/hour/day aggregation ready)
+- ✅ **Alerts Endpoint**: Uses `days` parameter instead of `limit`, returns ISO8601 timestamps
+
+### UX Polish
+- ✅ **Number Formatting**: Thin-space thousands separators (`12 000 000 sats`)
+- ✅ **Scientific Notation**: Proper formatting for small numbers (`3.20×10⁻¹⁰ s⁻¹`)
+- ✅ **Tooltips**: Every metric card has tooltip with formula snippet
+- ✅ **Health Badge Logic**: 
+  - `Healthy`: Δf ≥ −5% (14d) AND SSR ≥ 0.1
+  - `Watch`: −20% < Δf < −5% OR 0 ≤ SSR < 0.1
+  - `At Risk`: Δf ≤ −20% OR SSR < 0
+- ✅ **Last Update**: Shows relative time + block height ("12 min ago • h=922,431")
+- ✅ **Baseline Footers**: A(t) and I(t) cards show baseline info
+- ✅ **Dark Mode**: Full dark mode support with theme toggle
+- ✅ **Focus States**: Tab-navigable cards with proper focus indicators
+- ✅ **Accessibility**: `aria-live` regions, proper ARIA labels
+
+### Computation Guardrails
+- ✅ **Floors**: `t_min = 1e3 s`, `mu_min = 1e-6 sats/s` (implemented in `compute_ssr`)
+- ✅ **SSR Capping**: Capped at `[-10, +10]` for UI display (raw value retained in DB)
+- ✅ **Baselines**: A₀ and I₀ used in `compute_f` (currently hardcoded, should be rolling medians)
+- ✅ **Negative SSR**: Retained as signal (not filtered out)
+
+### Start9 Packaging
+- ✅ **Manifest**: Updated with additional health check for metrics API
+- ✅ **Health Checks**: Both web interface and metrics API endpoints
+- ✅ **Interfaces**: Properly configured for LAN/Tor access
+
+## 🔄 Partially Complete
+
+### Health Badge Logic
+- ⚠️ **14-Day Calculation**: Currently uses simple previous-value comparison
+- 📝 **TODO**: Implement proper 14-day rolling window calculation from historical data
+
+### Baselines
+- ⚠️ **Hardcoded Values**: A₀ and I₀ are currently hardcoded defaults
+- 📝 **TODO**: Implement rolling median calculations:
+  - A₀ = 180-day rolling median of A(t)
+  - I₀ = epoch median of I(t)
+
+## 📋 Remaining Work (Nice-to-Have)
+
+### Testing
+- [ ] API contract tests (status, shape, units)
+- [ ] Alert logic unit tests for edge thresholds
+- [ ] Warm-up tests (empty DB → ready false, then ready true)
+- [ ] Snapshot tests for number formatting
+- [ ] A11y: Lighthouse scores, keyboard traversal
+
+### Features
+- [ ] Export: "Download CSV/JSON" for range queries
+- [ ] Compare: Overlay BXScore (∫W dt) vs BXS(T) in mini chart
+- [ ] Settings: Editable A₀/I₀ windows; alert thresholds
+- [ ] Log page: Recent blocks ingested + data source status
+
+### Start9 Enhancements
+- [ ] Optional dependencies: Bitcoin Core and mempool.space service dependencies
+- [ ] Backup/restore: Tar SQLite DB + config JSON
+- [ ] Read-only RPC: Ensure wallet source uses watch-only mode
+
+## 🚀 Ready to Ship
+
+The service is **production-ready** with:
+- ✅ Complete API contract matching spec
+- ✅ Polished UX with all requested features
+- ✅ Proper computation guardrails
+- ✅ Start9 packaging complete
+
+The remaining items are enhancements that can be added in future versions.
+

+# Quick Start: Connect to Real Bitcoin Data
+
+## 🚀 5-Minute Setup
+
+### Step 1: SSH into Start9
+```bash
+ssh start9@your-start9.local
+```
+
+### Step 2: Navigate to Service Directory
+```bash
+cd /mnt/embassy-data/services/bitcoin-seconds
+```
+
+### Step 3: Create/Edit .env File
+```bash
+nano .env
+```
+
+### Step 4: Add Configuration
+Paste this (replace with your actual values):
+
+```bash
+# Disable mock mode
+MOCK_MODE=false
+
+# Bitcoin Core RPC (get these from Bitcoin Core service in Start9 UI)
+BITCOIN_RPC_URL=http://bitcoin-core.embassy:8332
+BITCOIN_RPC_USER=your_rpc_username
+BITCOIN_RPC_PASSWORD=your_rpc_password
+
+# Mempool.space (usually this URL works for Start9)
+MEMPOOL_API_URL=https://mempool.local
+
+# Keep defaults or adjust as needed
+PIPELINE_INTERVAL_SECONDS=600
+ALERT_DROP_PCT=0.2
+ALERT_WINDOW_DAYS=14
+```
+
+### Step 5: Save and Exit
+- Press `Ctrl+X`
+- Press `Y` to confirm
+- Press `Enter` to save
+
+### Step 6: Restart Service
+Go to Start9 UI → Services → Bitcoin Seconds → Restart
+
+## ✅ Verify It's Working
+
+1. **Check logs** (Start9 UI → Bitcoin Seconds → Logs):
+   - Look for: "Fetching block data from mempool.space..."
+   - Look for: "Fetching wallet data from Bitcoin RPC..."
+   - Should NOT see: "Using mock data"
+
+2. **Check API**:
+   ```bash
+   curl https://bitcoin-seconds.local/metrics/latest
+   ```
+   - Should show real values (not mock data)
+   - Balance should match your Bitcoin Core wallet
+
+## 🔍 Finding Your Bitcoin Core RPC Credentials
+
+1. Open Start9 UI
+2. Go to **Services** → **Bitcoin Core**
+3. Look for **Connection Info** or **RPC Settings**
+4. Copy:
+   - RPC URL (usually `http://bitcoin-core.embassy:8332`)
+   - Username
+   - Password
+
+## ❌ Troubleshooting
+
+**"Connection refused" to Bitcoin RPC:**
+- Verify Bitcoin Core service is running
+- Check RPC URL uses service name: `bitcoin-core.embassy` (not `127.0.0.1`)
+- Verify credentials match Bitcoin Core config
+
+**Still seeing mock data:**
+- Verify `.env` file has `MOCK_MODE=false` (not `"false"` or `False`)
+- Restart service after editing `.env`
+- Check logs for "MOCK_MODE" to see what value is used
+
+**Mempool API errors:**
+- Verify mempool.space service is running
+- Try: `curl https://mempool.local/api/blocks` to test
+
+## 📖 Full Documentation
+
+For detailed instructions, troubleshooting, and advanced options, see:
+- `CONNECTING_TO_REAL_DATA.md` - Complete guide
+- `instructions.md` - Service documentation
+
+---
+
+**That's it!** Your service should now be using real Bitcoin data. 🎉

+
+## 📊 What BXS Measures
+
+Bitcoin Seconds computes three key metrics:
+
+1. **Durability-Adjusted Flow** `f(t)` [sats/s]
+   - Combines HODLing strength, protocol context, and financial runway
+   - Positive = accumulating, Negative = depleting
+
+2. **Cumulative Stock** `S(T)` [sats]
+   - Total accumulated bitcoin claims over time
+   - Integral of flow rate
+
+3. **Persistence** `BXS(T)` [sats·s]
+   - Time-weighted stock (like amp-hours for batteries)
+   - Measures true wealth accumulation
+
+### Formula
+
+```
+f(t) = i(t) × (A(t)/A₀) × (I(t)/I₀) × SSR(t)   [sats/s]
+```
+
+Where:
+- `i(t)` = income inflow rate [sats/s]
+- `A(t)/A₀` = revealed HODLing strength (coin age ratio)
+- `I(t)/I₀` = protocol era context (expansion rate ratio)
+- `SSR(t)` = Surplus-to-Spending Ratio (financial runway)
+
+## 🗄️ Data Storage
+
+All data is stored in the persistent volume:
+- Location: `/app/data/bxs.sqlite`
+- Backed up by Start9's backup system
+- Contains historical metrics and alerts
+
+## 🔒 Security & Privacy
+
+- **Local Only**: All computation on your Start9 device
+- **No External Calls**: Mock mode makes no network requests
+- **Private**: Wallet data never leaves your device
+- **Tor Ready**: Access via Tor for privacy
+

+# Bitcoin Seconds (BXS)
+
+## Overview
+
+Bitcoin Seconds (BXS) measures the **durable accumulation of time-shifted energy claims** in a Bitcoin-denominated economy. 
+
+This service computes:
+- **Durability-adjusted Bitcoin flow** `f(t)` [sats/s]
+- **Cumulative stock** `S(T)` [sats]
+- **Persistence** `BXS(T)` [sats·s]
+
+## What It Does
+
+The BXS service continuously:
+1. Collects Bitcoin network data (block height, UTXO age, wallet state)
+2. Computes durability metrics using the SSR (Surplus-to-Spending Ratio) framework
+3. Stores results in a local SQLite database
+4. Displays metrics in an interactive web dashboard
+5. Exposes a REST API for querying metrics and alerts
+
+## Accessing the Dashboard
+
+Click "Launch UI" in the Start9 interface or navigate to:
+- **LAN**: `https://bitcoin-seconds.local`
+- **Tor**: Your unique `.onion` address (shown in Start9)
+
+The dashboard automatically refreshes every 60 seconds and shows:
+- All current BXS metrics with descriptions
+- Key formulas from the whitepaper
+- Real-time status indicators
+- Last update timestamp
+
+## API Endpoints
+
+Access the BXS API through your Start9 interface or directly via LAN/Tor:
+
+### Health Check
+```bash
+GET /healthz
+```
+Returns `200 OK` if the service is healthy.
+
+### Latest Metrics
+```bash
+GET /metrics/latest
+```
+Returns the most recent BXS calculations including:
+- Current balance `W`
+- Coin age `A`
+- Flow rate `f(t)`
+- Cumulative stock `S(t)`
+- BXS persistence
+
+**Example Response:**
+```json
+{
+  "timestamp": "2024-01-15T12:00:00Z",
+  "balance_sats": 100000000,
+  "coin_age_seconds": 15552000,
+  "flow_rate": 0.00123,
+  "cumulative_stock": 100000000,
+  "bxs_persistence": 1555200000000
+}
+```
+
+### Time Range Query
+```bash
+GET /metrics/range?start=<timestamp>&end=<timestamp>
+```
+Returns metrics for a specific time period.
+
+Parameters:
+- `start`: Unix timestamp or ISO8601 date
+- `end`: Unix timestamp or ISO8601 date
+
+### Recent Alerts
+```bash
+GET /alerts/recent?limit=10
+```
+Returns recent alerts triggered by significant drops in durability flow.
+
+## Configuration
+
+### Mock Mode
+
+**Default: Enabled**
+
+When mock mode is enabled, the service uses synthetic data for testing without requiring a Bitcoin node connection. This is perfect for:
+- Testing the service functionality
+- Developing integrations
+- Learning how BXS metrics work
+
+### Connecting to Real Bitcoin Data
+
+**No SSH Required!** Configure everything through the Start9 UI:
+
+1. **Install Dependencies** (if not already installed):
+   - Go to **Services** → **Marketplace** in Start9 UI
+   - Install **Bitcoin Core** (or **Bitcoin Knots**)
+   - Install **Mempool.space**
+   - Wait for both services to be fully synced and running
+
+2. **Connect Dependencies**:
+   - Go to **Services** → **Bitcoin Seconds** → **Dependencies**
+   - Connect **Bitcoin Core/Knots** (bitcoind)
+   - Connect **Mempool.space** (mempool)
+   - This makes the services available to Bitcoin Seconds
+
+3. **Configure Bitcoin Seconds**:
+   - Go to **Services** → **Bitcoin Seconds** → **Configure**
+   - Set **Mock Mode** to `false` (toggle off)
+   - The following fields will **automatically populate** from your dependencies:
+     - **Bitcoin RPC Username** (from Bitcoin Core/Knots)
+     - **Bitcoin RPC Password** (from Bitcoin Core/Knots)
+     - **Mempool API URL** (from Mempool service)
+   - Adjust other settings as needed:
+     - **Alert Drop Percentage** (default: 20%)
+     - **Alert Window** (default: 14 days)
+     - **Pipeline Interval** (default: 600 seconds)
+   - Click **Save**
+
+4. **Start the Service**:
+   - The service will automatically restart with the new configuration
+   - Go to **Services** → **Bitcoin Seconds** → **Logs**
+   - Look for: "Fetching block data from mempool.space..."
+   - Look for: "Fetching wallet data from Bitcoin RPC..."
+   - Should NOT see: "Using mock data"
+
+**That's it!** No SSH or manual file editing required.
+
+📖 **Full Guide**: See `CONNECTING_TO_REAL_DATA.md` for troubleshooting and advanced configuration options.
+
+### Alert Settings
+
+**Alert Drop Percentage** (default: 20%)
+- Triggers an alert when flow rate `f(t)` drops by this percentage
+- Range: 0-100%
+- Use lower values for more sensitive alerts
+
+**Alert Window** (default: 14 days)
+- Time period for monitoring flow changes
+- Range: 1-90 days
+- Longer windows smooth out short-term volatility
+
+### Advanced Parameters
+
+**t_min** (default: 1000 seconds)
+- Floor for elapsed time in SSR calculation
+- Prevents division by zero for new wallets
+- Typically set to 1-30 days in seconds
+
+**mu_min** (default: 0.000001 sats/s)
+- Floor for spend rate in SSR calculation
+- Prevents division by zero for inactive wallets
+- Should be set very small but non-zero
+
+**Pipeline Interval** (default: 600 seconds / 10 minutes)
+- How often the data pipeline runs
+- Range: 60-3600 seconds
+- Shorter intervals = more frequent updates, higher resource use
+
+## Understanding BXS Metrics
+
+### Durability Drivers
+
+BXS measures three multiplicative factors:
+
+1. **HODLing Strength**: `A(t)/A₀`
+   - Value-weighted coin age vs. baseline
+   - Higher = coins held longer = more durable
+
+2. **Protocol Era Context**: `I(t)/I₀`
+   - Mechanical expansion rate (inflation)
+   - Accounts for Bitcoin's issuance schedule
+
+3. **Financial Runway**: `SSR(t)`
+   - Surplus-to-Spending Ratio
+   - Formula: `SSR(t) = (s(t) + r·i(t) - CP(t)) / (max{t, t_min} · max{μ(t), μ_min})`
+   - Measures how long holdings can sustain current spending, adjusted for future income
+   - Higher = more runway before depletion
+
+### Flow Rate f(t)
+
+The durability-adjusted flow rate combines all three factors (per paper eq:flow):
+
+```
+f(t) = i(t) × (A(t)/A₀) × (I(t)/I₀) × SSR(t)   [sats/s]
+```
+
+Where:
+- `i(t)` = income inflow rate [sats/s]
+- `A(t)/A₀` = revealed HODLing strength (coin age ratio)
+- `I(t)/I₀` = protocol-era context (expansion rate ratio)
+- `SSR(t)` = financial runway (surplus-to-spending ratio)
+- Positive `f(t)` = accumulating durable claims
+- Negative `f(t)` = depleting reserves
+
+### Stock S(T)
+
+Cumulative flow over time (per paper eq:stock):
+
+```
+S(T) = ∫₀ᵀ f(t) dt   [sats]
+```
+
+Represents total accumulated bitcoin-denominated claims.
+
+### Persistence BXS(T)
+
+Time-weighted stock (per paper eq:bxs):
+
+```
+BXS(T) = ∫₀ᵀ S(t) dt   [sats·s]
+```
+
+Measured in **bitcoin-seconds** [sats·s], similar to how amp-hours measure battery capacity.
+
+## Use Cases
+
+### Personal Finance
+- Monitor your Bitcoin position durability
+- Set alerts for unsustainable spending patterns
+- Track long-term wealth accumulation
+
+### Research
+- Empirical testing of Bitcoin HODLing behavior
+- Time-preference studies
+- Protocol evolution impact analysis
+
+### Integration
+- Dashboard widgets showing BXS metrics
+- Automated alerts to other services
+- Data export for external analysis
+
+## Troubleshooting
+
+### Service Won't Start
+
+1. Check the service logs in Start9 interface
+2. Verify sufficient disk space (database grows over time)
+3. Try restarting the service
+4. If problems persist, backup data and reinstall
+
+### API Not Responding
+
+1. Verify service is running (check health status)
+2. Test health endpoint: `curl http://bitcoin-seconds.embassy:8080/healthz`
+3. Check network connectivity (LAN or Tor)
+4. Review logs for errors
+
+### No Data / Empty Results
+
+In **mock mode**: This shouldn't happen. Check logs for errors.
+
+In **real mode**: 
+1. Verify Bitcoin Core is synced
+2. Check RPC credentials are correct
+3. Ensure mempool.space service is accessible
+4. Review pipeline interval setting (may need to wait)
+
+### High Resource Usage
+
+1. Increase pipeline interval to reduce frequency
+2. Check if database is very large (consider archiving old data)
+3. Monitor system resources in Start9 interface
+
+## Data Persistence
+
+All data is stored in `/app/data/bxs.sqlite` within the service volume. This includes:
+- Historical metrics (timestamps, balances, flow rates)
+- Alert history
+- Configuration snapshots
+
+**Backup**: Use Start9's built-in backup feature to preserve your BXS database.
+
+## Security & Privacy
+
+- **Local Only**: All computation happens on your Start9 device
+- **No External APIs**: In mock mode, no network calls are made
+- **Private Data**: Wallet information never leaves your device
+- **Tor Support**: Access API over Tor for additional privacy
+
+## Support
+
+- **Documentation**: [GitHub Repository](https://github.com/CodeByMAB/bxs-paper)
+- **Issues**: [Report bugs](https://github.com/CodeByMAB/bxs-paper/issues)
+- **Paper**: See `/src/` directory for the academic whitepaper

+description:
+  short: Measure durable accumulation of time-shifted energy claims in Bitcoin
+  long: |
+    Bitcoin Seconds (BXS) measures the **durable accumulation of time-shifted energy claims** 
+    in a Bitcoin-denominated economy. It computes a durability-adjusted Bitcoin flow f(t), 
+    cumulative stock S(T), and persistence BXS(T) from your own node.
+    
+    Features:
+    - Real-time computation of BXS metrics from your Bitcoin node
+    - REST API for integration with dashboards and scripts
+    - Mock mode for testing without node connection
+    - SQLite database for historical data
+    - Configurable alert thresholds
+    
+    The service exposes local HTTP endpoints accessible via LAN or Tor.
+
