+# The Fossil Record — Attestation Archaeology Visualizer
+
+> **Like looking at geological layers, but for silicon.**
+
+A visual timeline showing every attestation from every miner since genesis, color-coded by architecture family. G4s as ancient amber strata, G5s layered above in copper, POWER8 in deep blue, modern x86 as pale recent sediment.
+
+![Fossil Record Preview](preview.png)
+
+## 🎯 Overview
+
+The Fossil Record is an interactive stratigraphy visualization of RustChain's mining hardware history. Each attestation is a fossil — a preserved trace of the silicon that secured the network. Older architectures form the deep geological foundation, with newer hardware deposited in layers above.
+
+### Features
+
+- **Interactive Timeline**: Click any data point to see detailed attestation information
+- **Architecture Layers**: Color-coded by CPU family, ordered from ancient to modern
+- **Epoch Markers**: Vertical lines mark major settlement epochs (every 25 epochs)
+- **First Appearance Markers**: ✨ indicates when new architectures first joined
+- **Hover Tooltips**: Instant access to miner counts, RTC earned, fingerprint quality
+- **Filtering**: Filter by time range, architecture, or minimum epoch
+- **Data Export**: Export filtered data to CSV for further analysis
+- **Sample Data Mode**: Demo mode with realistic generated data
+
+## 🚀 Quick Start
+
+### Option 1: View with Sample Data (Immediate)
+
+1. Open `fossils/index.html` in a web browser
+2. Click "🎲 Load Sample Data" to see the visualization in action
+3. Explore the data with hover and click interactions
+
+### Option 2: Serve with Live Data
+
+```bash
+# Start the HTTP server
+python3 fossils/fossil_record_export.py --serve --port 8080
+
+# Open in browser
+open http://localhost:8080/fossils/index.html
+```
+
+The server will:
+- Automatically find your RustChain database
+- Serve the visualizer at `/fossils/index.html`
+- Provide API endpoints for data access
+
+### Option 3: Export Data First
+
+```bash
+# Export attestation history to JSON
+python3 fossils/fossil_record_export.py \
+  --db /path/to/rustchain.db \
+  --export attestation_history.json
+
+# Export to CSV for analysis
+python3 fossils/fossil_record_export.py \
+  --db /path/to/rustchain.db \
+  --csv attestation_history.csv
+```

+## 🎨 Visualization Design
+
+### X-Axis: Time (Epochs)
+- Runs from genesis (epoch 0) to present
+- Major tick marks every 10 epochs
+- Settlement markers (dashed lines) every 25 epochs
+
+### Y-Axis: Architecture Layers
+- Ordered from oldest (bottom) to newest (top)
+- Each architecture has a fixed geological color
+- Labels show architecture family names
+
+### Data Points
+- **Size**: Proportional to number of active miners
+- **Color**: Architecture family
+- **Opacity**: 85% for visual depth
+- **Stroke**: White border for separation
+
+### Interactive Elements
+- **Hover**: Shows epoch, architecture, miner count, avg RTC, fingerprint quality
+- **Click**: Expands tooltip with sample miner IDs
+- **First Appearance**: ✨ marker at debut epoch

+
+## 🔧 Configuration
+
+### Environment Variables
+
+```bash
+# Path to RustChain database
+export RUSTCHAIN_DB_PATH=/root/rustchain/rustchain_v2.db
+
+# Server configuration
+export FOSSIL_PORT=8080
+export FOSSIL_HOST=0.0.0.0
+```
+
+### Database Schema
+
+The exporter queries these tables (if available):
+
+```sql
+-- Primary attestation table
+miner_attest_recent (
+    miner TEXT PRIMARY KEY,
+    device_arch TEXT,
+    device_family TEXT,
+    ts_ok INTEGER,
+    fingerprint_passed INTEGER,
+    entropy_score REAL,
+    warthog_bonus REAL
+)
+
+-- Historical fingerprints
+miner_fingerprint_history (
+    id INTEGER PRIMARY KEY,
+    miner TEXT,
+    ts INTEGER,
+    profile_json TEXT
+)
+```
+
+## 🌐 API Endpoints
+
+When running the HTTP server (`--serve`), these endpoints are available:
+
+### GET /api/attestations/history
+Returns full attestation history from the database.
+
+```json
+[
+  {
+    "epoch": 142,
+    "timestamp": 1740326400,
+    "miner_id": "g4-001",
+    "device_arch": "G4",
+    "device_family": "G4",
+    "device_model": "PowerBook G4",
+    "rtc_earned": 87.5,
+    "fingerprint_quality": 0.823,
+    "multiplier": 2.5
+  }
+]
+```
+
+### GET /api/attestations/sample
+Returns generated sample data for testing/demo.
+
+### GET /fossils/index.html
+Serves the visualization UI.
+
+## 🛠️ Development
+
+### Modifying the Visualization
+
+The visualization uses **D3.js v7** for rendering. Key sections:
+
+1. **Data Loading** (`loadData()`): Fetches from API or generates sample data
+2. **Aggregation** (`renderVisualization()`): Groups by epoch × architecture
+3. **Rendering**: Creates SVG circles with appropriate sizing and coloring
+4. **Interactions**: Tooltip show/hide, click handlers, filtering
+
+### Adding New Architectures
+
+Edit the `ARCHITECTURES` constant in `index.html`:
+
+```javascript
+const ARCHITECTURES = {
+    'NEW_ARCH': { 
+        color: '#hexcolor', 
+        label: 'Display Name', 
+        order: 12  // Higher = appears higher on Y-axis
+    },
+    // ...
+};
+```
+
+### Customizing Colors
+
+The color palette uses geological/mineralogical themes:
+- Ancient CPUs → Warm amber/copper tones
+- Modern CPUs → Cool grey/blue tones
+- Rare architectures → Distinctive colors (crimson, jade)

+
+## 🐛 Troubleshooting
+
+### "No database found"
+```bash
+# Specify database path explicitly
+python3 fossils/fossil_record_export.py \
+  --db /absolute/path/to/rustchain.db \
+  --export data.json
+```
+
+### Visualization not loading
+1. Check browser console for errors
+2. Verify D3.js CDN is accessible

+
+### Data looks incorrect
+1. Verify database schema matches expected tables
+2. Check architecture normalization in export script
+3. Review epoch calculation (genesis timestamp)
