+# GigLez - IoT RF Device Mapping Platform
+
+## Primary Directive
+
+Build a Wigle-like crowdsourced platform for mapping Sub-GHz RF IoT devices. Accept .sub/.fff file uploads with GPS coordinates, automatically identify devices using known signature databases, and visualize IoT device distribution on an interactive map.
+
+## Core Objectives
+
+### 1. Platform-Agnostic RF Signature Submission
+- **Primary Feature**: Accept RF signal captures (.sub, .fff files) with GPS coordinates from ANY capture device
+- **Submission Requirements**:
+  - GPS coordinates (latitude/longitude) - REQUIRED
+  - Timestamp - REQUIRED
+  - .sub or .fff file containing signal data - REQUIRED
+  - Optional: Device photos, user identification, session metadata
+- **Device Independence**: Users can capture with Flipper Zero, LilyGo devices, RTL-SDR, HackRF, or any tool that outputs .sub/.fff format
+
+### 2. Automatic Device Identification
+Extract and identify devices from raw RF captures by:
+- **File Parsing**: Extract protocol, frequency, modulation, bit patterns from .sub/.fff files
+- **Database Matching**: Compare against known signature databases (Flipper Zero, RTL_433)
+- **Confidence Scoring**: Rank matches by similarity (exact, partial, pattern-based)
+- **Community Verification**: Allow users to confirm/correct automatic identifications
+
+### 3. Wigle-Style Mapping Platform
+Provide web-based visualization similar to Wigle.net:
+- **Interactive Map**: Display captured devices with GPS markers
+- **Heatmap View**: Show device density by geographic area
+- **Search & Filter**: By device type, frequency, protocol, date range
+- **Statistics Dashboard**: Total captures, unique devices, geographic coverage
+- **Leaderboard**: Top contributors by uploads/verifications
+
+## Wigle.net Analysis & Implementation Strategy
+
+### Key Wigle.net Features to Replicate
+
+#### 1. Submission Workflow
+**Wigle Approach:**
+- CSV upload with standardized format
+- Required fields: MAC, SSID, GPS coords, timestamp
+- Pre-header with client metadata
+- Batch uploads supported
+
+**GigLez Implementation:**
+- Accept .sub/.fff files + GPS JSON/CSV
+- Required fields: GPS (lat/lon), timestamp, signal file
+- Upload via web interface or API
+- Support batch submissions (ZIP of .sub files + manifest.json)
+
+#### 2. Data Storage
+**Wigle Stats (2017):**
+- 349M WiFi networks
+- 7.8M cell towers
+- Billions of observations
+- GPS coordinates for 99%+ of records
+
+**GigLez Architecture:**
+- PostgreSQL with PostGIS for geospatial queries
+- Deduplicate by file hash + GPS proximity
+- Store both raw files and parsed metadata
+- Index by frequency, protocol, location, timestamp
+
+#### 3. Search & Discovery
+**Wigle Features:**
+- Text search (SSID, MAC)
+- Geographic search (bounding box, radius)
+- Advanced filters (encryption, date range)
+- Export to CSV/KML
+
+**GigLez Equivalent:**
+- Search by device type, manufacturer, protocol
+- Geographic search (radius, bounding box)
+- Filter by frequency, modulation, confidence score
+- Export to .sub, JSON, CSV, GeoJSON
+
+#### 4. Mapping Interface
+**Wigle UI:**
+- Zoom-based detail levels
+- Color coding by signal type/quality
+- Click for network details
+- Overlays from entire database
+
+**GigLez UI:**
+- Leaflet.js/Mapbox for mapping
+- Color by device type or frequency band
+- Marker clustering for performance
+- Click for device details (.sub file viewer)
+- Heatmap overlay for density
+
+#### 5. User Accounts & Gamification
+**Wigle System:**
+- User registration required
+- Upload tracking and statistics
+- Leaderboard (global/monthly)
+- Contribution milestones
+
+**GigLez System:**
+- Optional accounts (allow anonymous uploads)
+- Track uploads, identifications, verifications
+- Reputation score for accurate IDs
+- Badges for contributions (first capture in city, 100 devices, etc.)
+
+#### 6. API Access
+**Wigle API:**
+- JSON-based RPC (not REST)
+- Authentication via API token
+- Query endpoints for searching
+- Upload endpoints for submissions
+- Rate limiting
+
+**GigLez API:**
+- RESTful JSON API
+- JWT tokens + API keys
+- Endpoints:
+  - `POST /api/submit` - Upload captures
+  - `GET /api/search` - Query database
+  - `GET /api/devices/{id}` - Device details
+  - `GET /api/heatmap` - Density data
+  - `GET /api/stats` - Platform statistics
+
+### Differences from Wigle
+
+| Feature | Wigle.net | GigLez |
+|---------|-----------|--------|
+| **Data Type** | WiFi, Bluetooth, Cellular | Sub-GHz IoT RF (300-928 MHz) |
+| **Submission Format** | CSV | .sub/.fff files + GPS |
+| **Identification** | MAC/SSID (exact) | Protocol signature matching (fuzzy) |
+| **Focus** | Network mapping | Device type identification |
+| **Privacy** | Public by default | Opt-in sharing, anonymization |
+

+    }
+  ]
+}
+```
+
+#### CSV Submission Format (Alternative)
+```csv
+latitude,longitude,timestamp,filename,accuracy,altitude
+40.7128,-74.0060,2025-01-11T20:30:00Z,capture_001.sub,5.0,10.5

+```
+
+### Device Signature Matching Pipeline
+
+#### Step 1: Parse .sub File
+```python
+def parse_sub_file(file_path):
+    """Extract metadata from .sub file"""
+    metadata = {
+        'frequency': None,
+        'protocol': None,
+        'modulation': None,
+        'bit_length': None,
+        'key_data': None,
+        'timing': None,
+        'raw_data': None
+    }
+
+    with open(file_path) as f:
+        for line in f:
+            if ':' in line:
+                key, value = line.split(':', 1)
+                # Map to metadata fields
+
+    return metadata
+```
+
+#### Step 2: Match Against Signature Database
+```python
+def match_signature(metadata):
+    """
+    Match parsed metadata against known signatures
+    Returns: [(device_id, confidence), ...]
+    """
+    matches = []
+
+    # Exact match: protocol + frequency + bit length
+    exact = query_exact_match(
+        metadata['protocol'],
+        metadata['frequency'],
+        metadata['bit_length']
+    )
+    if exact:
+        matches.append((exact.device_id, 1.0))
+
+    # Partial match: protocol + frequency
+    partial = query_partial_match(
+        metadata['protocol'],
+        metadata['frequency']
+    )
+    for match in partial:
+        matches.append((match.device_id, 0.8))
+
+    # Pattern match: bit pattern similarity
+    if metadata['key_data']:
+        pattern_matches = match_bit_patterns(metadata['key_data'])
+        matches.extend(pattern_matches)
+
+    # Timing match: for RAW files
+    if metadata['raw_data']:
+        timing_matches = match_timing_patterns(metadata['raw_data'])
+        matches.extend(timing_matches)
+
+    # Sort by confidence, deduplicate
+    return sorted(set(matches), key=lambda x: x[1], reverse=True)
+```
+
+#### Step 3: Store Results
+```python
+def store_capture(file_path, gps_coords, matches):
+    """Store capture with matched device(s)"""
+    capture = {
+        'latitude': gps_coords['lat'],
+        'longitude': gps_coords['lon'],
+        'timestamp': gps_coords['timestamp'],
+        'file_hash': sha256(file_path),
+        'file_path': upload_to_storage(file_path),
+        **parse_sub_file(file_path)
+    }
+
+    # Store capture
+    capture_id = db.captures.insert(capture)
+
+    # Store top 3 matches
+    for device_id, confidence in matches[:3]:
+        db.capture_matches.insert({
+            'capture_id': capture_id,
+            'device_id': device_id,
+            'confidence': confidence,
+            'method': 'auto'
+        })
+
+    return capture_id
+```

+# GigLez Database Setup Guide
+
+## Prerequisites
+
+- ✅ PostgreSQL 16+ installed
+- ✅ PostGIS 3.4+ extension available
+- ✅ Python 3.8+ with dependencies from requirements.txt
+
+## Quick Start
+
+### Step 1: Run Database Setup Script
+
+```bash
+cd /home/dell/coding/giglez
+./scripts/setup_database.sh
+```
+
+This script will:
+1. Create PostgreSQL user `giglez_user`
+2. Create database `giglez`
+3. Enable PostGIS extension
+4. Grant necessary permissions
+
+**Default Credentials:**
+- **User**: giglez_user
+- **Password**: giglez_secure_password_2026
+- **Database**: giglez
+- **Host**: localhost
+- **Port**: 5432
+
+⚠️ **Security Note**: Change the password in production!
+
+### Step 2: Create Database Schema
+
+```bash
+psql -U giglez_user -d giglez -h localhost -f scripts/create_schema.sql
+```
+
+Or if you have sudo access:
+
+```bash
+sudo -u postgres psql -d giglez -f scripts/create_schema.sql
+```
+
+This will create:
+- ✅ 15 tables (captures, devices, sessions, signatures, etc.)
+- ✅ PostGIS geometry columns and spatial indexes
+- ✅ Materialized views for performance
+- ✅ Triggers for automatic statistics updates
+- ✅ Functions for geospatial calculations
+
+### Step 3: Configure Environment
+
+```bash
+# Copy environment template
+cp .env.example .env
+
+# Edit with your configuration
+nano .env
+```
+
+Update these values:
+```env
+GIGLEZ_DB_PASSWORD=your_secure_password_here
+GIGLEZ_STORAGE_PATH=/your/storage/path
+```
+
+### Step 4: Test Connection
+
+```bash
+python3 config/database.py
+```
+
+Expected output:
+```
+Testing database connection...
+✅ Database connection test successful
+Testing PostGIS extension...
+✅ PostGIS available: 3.4 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
+✅ Database fully operational
+```
+
+## Database Schema Overview
+
+### Core Tables
+
+#### captures
+Primary storage for RF signal captures with GPS coordinates.
+- **Primary Key**: `file_hash` (SHA256 of .sub file)
+- **Geospatial**: `geom` column with GIST index
+- **Deduplication**: Automatic via primary key constraint
+
+#### devices
+Known IoT device types from signature databases.
+- Manufacturer, model, device type
+- RF characteristics (frequency, modulation, protocol)
+- Full-text search enabled
+
+#### sessions
+Wardriving session grouping (Wigle pattern).
+- Groups related captures
+- Tracks statistics (total captures, unique devices)
+- Bounding box for geographic extent
+
+#### signatures
+Protocol signatures for device matching.
+- Bit patterns with masks
+- Timing patterns for RAW signals
+- Confidence weighting
+
+#### capture_matches
+Many-to-many mapping of captures to devices.
+- Multiple devices can match one capture
+- Confidence scores (0.0 - 1.0)
+- Match method tracking
+
+### Supporting Tables
+
+- **users**: Optional user accounts
+- **identifications**: Community device submissions
+- **votes**: Voting on identifications
+- **upload_markers**: Incremental sync tracking (Wigle pattern)
+- **flipper_signatures**: Flipper Zero specific data
+- **rtl433_protocols**: RTL_433 specific data
+
+### Materialized Views
+
+#### device_statistics
+Pre-computed device statistics for performance.
+```sql
+REFRESH MATERIALIZED VIEW CONCURRENTLY device_statistics;
+```
+
+#### geographic_heatmap
+Aggregated capture density by location.
+```sql
+REFRESH MATERIALIZED VIEW CONCURRENTLY geographic_heatmap;
+```
+
+## Common Operations
+
+### Query Captures Near Location
+
+```sql
+-- Within 1km radius
+SELECT c.*, d.manufacturer, d.model
+FROM captures c
+LEFT JOIN devices d ON c.device_id = d.id
+WHERE calculate_distance(c.latitude, c.longitude, 40.7128, -74.0060) <= 1.0
+ORDER BY c.captured_at DESC;
+
+-- Or using PostGIS (faster)
+SELECT c.*, d.manufacturer, d.model
+FROM captures c
+LEFT JOIN devices d ON c.device_id = d.id
+WHERE ST_DWithin(
+    c.geom,
+    ST_SetSRID(ST_MakePoint(-74.0060, 40.7128), 4326)::geography,
+    1000  -- meters
+)
+ORDER BY c.captured_at DESC;
+```
+
+### Query by Bounding Box
+
+```sql
+SELECT c.*
+FROM captures c
+WHERE c.geom && ST_MakeEnvelope(-74.1, 40.6, -73.9, 40.8, 4326)
+LIMIT 100;
+```
+
+### Get Unidentified Captures
+
+```sql
+SELECT c.file_hash, c.frequency, c.protocol, c.latitude, c.longitude
+FROM captures c
+WHERE c.device_id IS NULL
+    AND c.protocol IS NOT NULL
+ORDER BY c.captured_at DESC
+LIMIT 100;
+```
+
+### Top Devices by Capture Count
+
+```sql
+SELECT
+    d.manufacturer,
+    d.model,
+    d.device_type,
+    COUNT(c.file_hash) as captures
+FROM devices d
+JOIN captures c ON c.device_id = d.id
+GROUP BY d.id, d.manufacturer, d.model, d.device_type
+ORDER BY captures DESC
+LIMIT 20;
+```
+
+### Heatmap Data
+
+```sql
+SELECT
+    lat_bucket,
+    lon_bucket,
+    capture_count,
+    unique_devices
+FROM geographic_heatmap
+WHERE capture_count > 5
+ORDER BY capture_count DESC
+LIMIT 1000;
+```
+
+## Performance Tuning
+
+### Indexes
+
+All critical indexes are created automatically:
+- Geospatial: GIST indexes on `geom` column
+- Foreign keys: B-tree indexes
+- Query fields: Indexes on frequency, protocol, timestamp
+
+### Batch Inserts
+
+Use transaction batching for bulk inserts (Wigle pattern):
+
+```python
+from config.database import DatabaseSession
+
+BATCH_SIZE = 512  # Wigle optimal batch size
+
+with DatabaseSession() as session:
+    for i in range(0, len(captures), BATCH_SIZE):
+        batch = captures[i:i+BATCH_SIZE]
+        session.bulk_insert_mappings(Capture, batch)
+```
+
+### Connection Pooling
+
+Configured in `config/database.py`:
+- Pool size: 10 connections
+- Max overflow: 20 connections
+- Pre-ping: True (verify before use)
+
+### Materialized View Refresh
+
+Set up cron job for periodic refresh:
+
+```bash
+# Add to crontab
+0 */6 * * * psql -U giglez_user -d giglez -c "REFRESH MATERIALIZED VIEW CONCURRENTLY device_statistics;"
+0 */6 * * * psql -U giglez_user -d giglez -c "REFRESH MATERIALIZED VIEW CONCURRENTLY geographic_heatmap;"
+```
+
+## Backup & Maintenance
+
+### Backup Database
+
+```bash
+pg_dump -U giglez_user -d giglez -h localhost -F c -f giglez_backup_$(date +%Y%m%d).dump
+```
+
+### Restore Database
+
+```bash
+pg_restore -U giglez_user -d giglez -h localhost giglez_backup_20260112.dump
+```
+
+### Vacuum and Analyze
+
+```bash
+psql -U giglez_user -d giglez -h localhost -c "VACUUM ANALYZE;"
+```
+
+### Check Database Size
+
+```sql
+SELECT
+    pg_size_pretty(pg_database_size('giglez')) as db_size,
+    pg_size_pretty(pg_total_relation_size('captures')) as captures_size,
+    pg_size_pretty(pg_total_relation_size('devices')) as devices_size;
+```
+
+## Troubleshooting
+
+### Connection Refused
+
+```bash
+# Check PostgreSQL status
+sudo systemctl status postgresql
+
+# Start PostgreSQL
+sudo systemctl start postgresql
+
+# Enable on boot
+sudo systemctl enable postgresql
+```
+
+### Permission Denied
+
+```bash
+# Grant permissions
+sudo -u postgres psql -d giglez -c "GRANT ALL ON SCHEMA public TO giglez_user;"
+sudo -u postgres psql -d giglez -c "GRANT ALL ON ALL TABLES IN SCHEMA public TO giglez_user;"
+sudo -u postgres psql -d giglez -c "GRANT ALL ON ALL SEQUENCES IN SCHEMA public TO giglez_user;"
+```
+
+### PostGIS Not Found
+
+```bash
+# Install PostGIS extension
+sudo apt install postgresql-16-postgis-3
+
+# Enable in database
+psql -U giglez_user -d giglez -h localhost -c "CREATE EXTENSION postgis;"
+```
+
+### Test PostGIS
+
+```sql
+SELECT PostGIS_Version();
+SELECT ST_AsText(ST_MakePoint(-74.0060, 40.7128));
+```
+
+## Architecture Decisions
+
+Based on Wigle.net analysis (see `docs/wigle_analysis.md`):
+
+1. **SHA256 primary key**: Automatic deduplication of .sub files
+2. **PostGIS geometry**: Efficient geospatial queries (GIST indexes)
+3. **3-table design**: captures → capture_matches → devices
+4. **Upload markers**: Incremental sync for resumable uploads
+5. **Materialized views**: Pre-computed statistics for performance
+6. **Batch transactions**: 512 operations per commit
+7. **Connection pooling**: 10 base + 20 overflow connections
+
+## Next Steps
+
+After database setup:
+
+1. ✅ Implement SQLAlchemy ORM models (`src/database/models.py`)
+2. ✅ Create GPS validator module (`src/gps/validator.py`)
+3. ✅ Set up Alembic migrations (`alembic/`)
+4. ✅ Build FastAPI upload endpoints (`src/api/`)
+5. ✅ Import signature databases (Flipper Zero, RTL_433)
+
+See `IMPLEMENTATION_PLAN.md` for complete roadmap.

+# GigLez Deployment Considerations: Development vs Production
+
+**Created**: 2026-01-12
+**Purpose**: Identify critical differences between local development and production deployment
+
+---
+
+## Executive Summary
+
+GigLez needs to support two distinct deployment scenarios:
+
+1. **Local Development** (Termux on Android)
+   - Resource-constrained (mobile device)
+   - Single-user access
+   - Direct USB serial communication
+   - Local file storage
+   - Development/testing workflow
+
+2. **Production Server** (Cloud/VPS)
+   - Multi-user platform
+   - Public API access
+   - No hardware connection
+   - Object storage for files
+   - High availability requirements
+
+**Key Insight**: We need a **modular architecture** that supports both scenarios without code duplication.
+
+---
+
+## Architecture Strategy
+
+### Hybrid Architecture: "Capture" vs "Platform" Mode

+
+## Detailed Comparison
+
+### 1. Hardware Access
+
+#### Development (Termux)
+- **T-Embed Connection**: USB serial communication (pyserial)
+- **GPS Source**: Android native GPS via SL4A or Termux:API
+- **Real-time Capture**: Direct signal scanning and capture
+- **Storage**: Local filesystem on Android device
+
+**Implications**:
+- Need hardware abstraction layer
+- Support offline operation
+- Handle USB disconnections
+- Batch upload when network available
+
+#### Production (Server)
+- **No Hardware**: Accept pre-captured .sub files only
+- **GPS Source**: Embedded in upload manifest
+- **No Real-time**: Historical data only
+- **Storage**: Object storage (S3, MinIO, or filesystem)
+
+**Implications**:
+- No serial communication code needed
+- Network-dependent operation
+- Focus on file processing pipeline
+- Horizontal scaling possible
+
+**Solution**:
+```python
+# Abstract hardware interface
+class CaptureSource(ABC):
+    @abstractmethod
+    def scan_signals(self): pass
+
+    @abstractmethod
+    def get_gps(self): pass
+
+class TEmbedSource(CaptureSource):
+    """Development: Direct hardware"""
+    pass
+
+class UploadSource(CaptureSource):
+    """Production: File uploads"""
+    pass
+```
+
+---
+
+### 2. Database Configuration
+
+#### Development (Termux)
+- **PostgreSQL**: Local installation via `pkg install postgresql`
+- **Host**: localhost or 127.0.0.1
+- **Port**: 5432
+- **Connections**: Small pool (5 + 5 overflow)
+- **Storage**: Device internal storage or SD card
+
+**Considerations**:
+- Limited RAM on mobile devices
+- Smaller connection pool
+- May need to tune PostgreSQL for mobile
+- Backup to SD card or cloud
+
+#### Production (Server)
+- **PostgreSQL**: Dedicated server or managed database (RDS, Cloud SQL)
+- **Host**: Remote database server
+- **Port**: 5432 (or custom)
+- **Connections**: Larger pool (20 + 40 overflow)
+- **Storage**: SSD/NVMe for performance
+
+**Considerations**:
+- Connection pooling via PgBouncer
+- Read replicas for scaling
+- Automated backups
+- Point-in-time recovery
+
+**Solution**: Environment-based configuration
+```bash
+# Development (.env)
+GIGLEZ_DB_HOST=localhost
+GIGLEZ_DB_POOL_SIZE=5
+GIGLEZ_DB_MAX_OVERFLOW=5
+
+# Production (.env.production)
+GIGLEZ_DB_HOST=db.giglez.com
+GIGLEZ_DB_POOL_SIZE=20
+GIGLEZ_DB_MAX_OVERFLOW=40
+```
+
+---
+
+### 3. File Storage
+
+#### Development (Termux)
+- **Location**: `/data/data/com.termux/files/home/giglez/storage/`
+- **Structure**: Organized by session/date
+- **Size**: Limited by device storage (typically < 64GB)
+- **Access**: Direct filesystem access
+
+**Structure**:
+```
+storage/
+├── captures/
+│   ├── 2026-01-12/
+│   │   ├── session_abc123/
+│   │   │   ├── capture_001.sub
+│   │   │   ├── capture_002.sub
+│   │   │   └── manifest.json
+```
+
+#### Production (Server)
+- **Location**: Object storage (S3, MinIO, GCS) or networked filesystem
+- **Structure**: Content-addressed by file hash
+- **Size**: Unlimited (cloud storage)
+- **Access**: Via storage API or CDN
+
+**Structure**:

+│   │   └── abc123...def456.sub  # First 2+2 chars of hash for sharding
+```
+
+**Solution**: Storage abstraction
+```python
+class StorageBackend(ABC):
+    @abstractmethod
+    def save_file(self, file_hash: str, content: bytes): pass
+
+    @abstractmethod
+    def get_file(self, file_hash: str) -> bytes: pass
+
+class LocalStorage(StorageBackend):
+    """Development: Filesystem"""
+    pass
+
+class S3Storage(StorageBackend):
+    """Production: S3-compatible storage"""
+    pass
+```
+

+
+### 4. API Access & Security
+
+#### Development (Termux)
+- **Access**: Local only (127.0.0.1) or local network
+- **Port**: 8000 (or any available)
+- **HTTPS**: Not required (localhost)
+- **Authentication**: Optional (single user)
+- **CORS**: Permissive (development)
+- **Rate Limiting**: None needed
+
+**Use Cases**:
+- Testing API endpoints
+- Web UI development
+- Local data management
+- Debugging
+
+#### Production (Server)
+- **Access**: Public internet
+- **Port**: 443 (HTTPS) behind reverse proxy
+- **HTTPS**: Required (Let's Encrypt)
+- **Authentication**: JWT + API keys mandatory
+- **CORS**: Strict origin whitelisting
+- **Rate Limiting**: Aggressive (per-user, per-IP)
+
+**Security Requirements**:
+- Nginx/Caddy reverse proxy
+- SSL/TLS certificates
+- API key rotation
+- Request validation
+- SQL injection prevention
+- File upload limits
+- DDoS protection
+
+**Solution**: Environment-based security
+```python
+# config/security.py
+if os.getenv("GIGLEZ_MODE") == "production":
+    REQUIRE_AUTH = True
+    RATE_LIMIT = "10/minute"
+    ALLOWED_ORIGINS = ["https://giglez.com"]
+else:
+    REQUIRE_AUTH = False
+    RATE_LIMIT = None
+    ALLOWED_ORIGINS = ["*"]
+```
+
+---
+
+### 5. Performance & Scaling
+
+#### Development (Termux)
+- **Workers**: 1 Uvicorn worker
+- **Concurrency**: Minimal (single user)
+- **Caching**: In-memory only (LRU)
+- **Background Tasks**: Simple queue or synchronous
+- **Resource Limits**: RAM < 2GB, CPU 2-4 cores
+
+**Optimization Focus**:
+- Memory efficiency
+- Minimal background processes
+- Battery life considerations
+- Offline operation
+
+#### Production (Server)
+- **Workers**: Multiple Uvicorn workers (4-8)
+- **Concurrency**: High (100+ concurrent users)
+- **Caching**: Redis + LRU
+- **Background Tasks**: Celery + RabbitMQ/Redis
+- **Resource Limits**: RAM 8-32GB, CPU 4-16 cores
+
+**Optimization Focus**:
+- Query performance
+- Connection pooling
+- Horizontal scaling
+- CDN for static assets
+- Load balancing
+
+**Solution**: Conditional imports
+```python
+# src/api/main.py
+if PRODUCTION_MODE:
+    from celery import Celery
+    celery_app = Celery('giglez', broker='redis://localhost')
+else:
+    # Use FastAPI BackgroundTasks for development
+    celery_app = None
+```
+
+---
+
+### 6. Logging & Monitoring
+
+#### Development (Termux)
+- **Logging**: Console output (stdout)
+- **Level**: DEBUG
+- **Format**: Colorized, verbose
+- **Storage**: Optional file logging
+- **Monitoring**: Manual observation
+
+**Example**:
+```python
+logger.add(sys.stdout, level="DEBUG", colorize=True)
+```
+
+#### Production (Server)
+- **Logging**: Structured JSON to file + syslog
+- **Level**: INFO/WARNING
+- **Format**: JSON for parsing
+- **Storage**: Log rotation + cloud storage
+- **Monitoring**: Prometheus + Grafana, error tracking (Sentry)
+
+**Example**:
+```python
+logger.add(
+    "/var/log/giglez/app.log",
+    level="INFO",
+    format="{time:YYYY-MM-DD HH:mm:ss} | {level} | {message}",
+    rotation="100 MB",
+    compression="gz"
+)
+```
+
+**Solution**: Environment-based logging
+```python
+# config/logging.py
+if PRODUCTION_MODE:
+    setup_production_logging()
+else:
+    setup_development_logging()
+```
+
+---
+
+### 7. Backup & Disaster Recovery
+
+#### Development (Termux)
+- **Database**: Manual pg_dump to SD card
+- **Files**: Synced to cloud storage (Google Drive, Dropbox)
+- **Frequency**: On-demand
+- **Recovery**: Restore from local backups
+
+#### Production (Server)
+- **Database**: Automated daily backups with PITR
+- **Files**: Object storage replication (S3 versioning)
+- **Frequency**: Hourly incremental, daily full
+- **Recovery**: Automated restore procedures
+
+**Backup Strategy**:
+```bash
+# Development
+pg_dump giglez > /sdcard/giglez_backup_$(date +%Y%m%d).sql
+
+# Production
+pg_dump giglez | gzip | aws s3 cp - s3://giglez-backups/$(date +%Y%m%d).sql.gz
+```
+
+---
+
+### 8. Network Considerations
+
+#### Development (Termux)
+- **Connectivity**: WiFi or cellular (intermittent)
+- **Bandwidth**: Potentially limited (mobile data)
+- **Latency**: Variable (mobile networks)
+- **Offline Support**: Critical (wardriving in field)
+
+**Implications**:
+- Queue uploads for when network available
+- Support offline capture and analysis
+- Minimize API calls
+- Compress uploads
+
+#### Production (Server)
+- **Connectivity**: Always online (datacenter)
+- **Bandwidth**: High (1Gbps+)
+- **Latency**: Low (< 50ms typical)
+- **Offline Support**: Not applicable
+
+**Implications**:
+- Assume network availability
+- No offline mode needed
+- Can make external API calls freely
+- Stream large responses
+
+**Solution**: Offline queue
+```python
+# src/capture/uploader.py
+class UploadQueue:
+    def queue_capture(self, capture_data):
+        if network_available():
+            upload_immediately(capture_data)
+        else:
+            save_to_local_queue(capture_data)
+
+    def process_queue(self):
+        """Called when network becomes available"""
+        for item in get_queued_items():
+            try:
+                upload_immediately(item)
+                mark_as_uploaded(item)
+            except NetworkError:
+                break  # Stop and try again later
+```
+
+---
+
+## Configuration Strategy
+
+### Environment Variables Approach
+
+Use different `.env` files for each environment:
+
+```bash
+# .env.development (Termux)
+GIGLEZ_MODE=development
+GIGLEZ_DB_HOST=localhost
+GIGLEZ_DB_POOL_SIZE=5
+GIGLEZ_API_HOST=127.0.0.1
+GIGLEZ_API_PORT=8000
+GIGLEZ_STORAGE_TYPE=filesystem
+GIGLEZ_STORAGE_PATH=/data/data/com.termux/files/home/giglez/storage
+GIGLEZ_REQUIRE_AUTH=false
+GIGLEZ_LOG_LEVEL=DEBUG
+GIGLEZ_ENABLE_HARDWARE=true
+GIGLEZ_TEMBED_PORT=/dev/ttyUSB0
+
+# .env.production (Server)
+GIGLEZ_MODE=production
+GIGLEZ_DB_HOST=db.giglez.com
+GIGLEZ_DB_POOL_SIZE=20
+GIGLEZ_API_HOST=0.0.0.0
+GIGLEZ_API_PORT=8000
+GIGLEZ_STORAGE_TYPE=s3
+GIGLEZ_STORAGE_BUCKET=giglez-captures
+GIGLEZ_REQUIRE_AUTH=true
+GIGLEZ_LOG_LEVEL=INFO
+GIGLEZ_ENABLE_HARDWARE=false
+```
+
+### Configuration Loading
+
+```python
+# config/settings.py
+import os
+from enum import Enum
+
+class DeploymentMode(Enum):
+    DEVELOPMENT = "development"
+    PRODUCTION = "production"
+
+class Settings:
+    def __init__(self):
+        self.mode = DeploymentMode(os.getenv("GIGLEZ_MODE", "development"))
+
+    @property
+    def is_production(self) -> bool:
+        return self.mode == DeploymentMode.PRODUCTION
+
+    @property
+    def is_development(self) -> bool:
+        return self.mode == DeploymentMode.DEVELOPMENT
+
+    @property
+    def enable_hardware(self) -> bool:
+        """Only enable hardware access in development"""
+        return os.getenv("GIGLEZ_ENABLE_HARDWARE", "false").lower() == "true"
+
+    @property
+    def storage_backend(self) -> str:
+        return os.getenv("GIGLEZ_STORAGE_TYPE", "filesystem")
+
+settings = Settings()
+```

+
+---
+
+## Implementation Recommendations
+
+### 1. Use Feature Flags
+
+```python
+# src/api/main.py
+from config.settings import settings
+
+app = FastAPI()
+
+# Conditional hardware endpoints
+if settings.enable_hardware:
+    @app.post("/api/capture/start")
+    async def start_capture():
+        # Only available in Termux mode
+        pass
+
+# Always available endpoints
+@app.post("/api/captures/upload")
+async def upload_captures():
+    # Available in both modes
+    pass
+```
+
+### 2. Storage Abstraction
+
+```python
+# config/storage.py
+from src.core.storage import LocalStorage, S3Storage
+
+def get_storage_backend():
+    if settings.storage_backend == "s3":
+        return S3Storage(
+            bucket=os.getenv("GIGLEZ_STORAGE_BUCKET"),
+            access_key=os.getenv("AWS_ACCESS_KEY_ID"),
+            secret_key=os.getenv("AWS_SECRET_ACCESS_KEY")
+        )
+    else:
+        return LocalStorage(
+            base_path=os.getenv("GIGLEZ_STORAGE_PATH")
+        )
+
+storage = get_storage_backend()
+```
+
+### 3. Optional Dependencies
+
+```python
+# requirements.txt (core)
+fastapi==0.109.0
+sqlalchemy==2.0.25
+psycopg2-binary==2.9.9
+...
+
+# requirements-dev.txt (Termux additions)
+-r requirements.txt
+pyserial==3.5
+aioserial==1.3.2
+
+# requirements-prod.txt (Server additions)
+-r requirements.txt
+boto3==1.34.0  # S3 storage
+redis==5.0.1   # Caching
+celery==5.3.4  # Background tasks
+gunicorn==21.2.0  # WSGI server
+```
+
+### 4. Graceful Degradation
+
+```python
+# src/api/routes/captures.py
+@app.post("/api/captures/upload")
+async def upload_captures(files: List[UploadFile]):
+    # Core functionality works in both modes
+    captures = []
+
+    for file in files:
+        # Parse .sub file (works everywhere)
+        metadata = parse_sub_file(file)
+
+        # Store file (abstracted)
+        storage.save_file(metadata.file_hash, file.content)
+
+        # Save to database (works everywhere)
+        capture = Capture(**metadata)
+        db.add(capture)
+
+        captures.append(capture)
+
+    db.commit()
+
+    # Background matching (production) or synchronous (development)
+    if settings.is_production:
+        celery_app.send_task('match_signatures', args=[capture.file_hash])
+    else:
+        match_signatures_sync(capture.file_hash)
+
+    return {"uploaded": len(captures)}
+```

+
+## Performance Considerations
+
+### Development (Termux) Optimizations
+- Smaller connection pool (5 + 5)
+- In-memory caching only
+- Synchronous processing (no Celery)
+- Minimal logging
+- Local file storage
+
+### Production (Server) Optimizations
+- Larger connection pool (20 + 40)
+- Redis caching
+- Async background tasks (Celery)
+- Structured logging with rotation
+- CDN for file delivery
+- Read replicas for scaling
+- Materialized view refresh (cron)
+
+---
+
+## Cost Considerations
+
+### Development (Termux)
+- **Hardware**: LilyGo T-Embed (~$30-50)
+- **Android Device**: Existing phone/tablet
+- **Infrastructure**: $0 (local)
+- **Storage**: Device storage only
+- **Total**: ~$30-50 one-time
+
+### Production (Server)
+- **VPS**: $10-50/month (2-8GB RAM)
+- **Database**: Included or $10-30/month (managed)
+- **Storage**: $0.02/GB/month (S3) or included (filesystem)
+- **Bandwidth**: Typically included (1-5TB)
+- **Domain**: $10-15/year
+- **SSL**: $0 (Let's Encrypt)
+- **Total**: $10-80/month
+
+---
+
+## Recommended Phase 2 Approach
+
+### Build for Both from the Start
+
+**Strategy**: Implement the API with abstraction layers that work in both environments.
+
+**Implementation Order**:
+1. ✅ Core API structure (FastAPI app)
+2. ✅ Storage abstraction (filesystem + S3)
+3. ✅ Upload endpoint (works in both modes)
+4. ✅ Authentication (optional in dev, required in prod)
+5. ✅ Background tasks (sync in dev, Celery in prod)
+6. ✅ Environment-based configuration
+
+**Key Principle**:
+> Write code that works in both environments by default, with conditional imports/features for mode-specific functionality.
+
+---
+
+## Summary: Key Differences
+
+| Aspect | Development (Termux) | Production (Server) |
+|--------|---------------------|---------------------|
+| **Hardware** | T-Embed USB + GPS | None (file uploads) |
+| **Users** | Single user | Multi-user |
+| **Database** | Local PostgreSQL (small pool) | Remote PostgreSQL (large pool) |
+| **Storage** | Local filesystem | S3/object storage |
+| **API Access** | localhost only | Public internet |
+| **Security** | Optional auth | Required auth + HTTPS |
+| **Background Tasks** | Synchronous | Celery async |
+| **Caching** | In-memory LRU | Redis + LRU |
+| **Logging** | Console (DEBUG) | File + JSON (INFO) |
+| **Monitoring** | Manual | Automated (Prometheus) |
+| **Scaling** | N/A | Horizontal |
+| **Cost** | $0/month | $10-80/month |
+
+---
+
+## Next Steps
+
+Before implementing Phase 2, we need to:
+
+1. ✅ **Create environment configuration** (`.env.development`, `.env.production`)
+2. ✅ **Implement storage abstraction** (`src/core/storage/`)
+3. ✅ **Create settings module** (`config/settings.py`)
+4. ✅ **Document deployment procedures** (development guide, production guide)
+5. ✅ **Begin FastAPI implementation** with environment awareness
+
+**Recommendation**: Start with a **shared API implementation** that works in both modes, then add mode-specific features as needed.
+
+---
+
+**Document Version**: 1.0
+**Status**: Ready for Phase 2 Implementation
+**Next Action**: Create environment-aware FastAPI application structure

+# GigLez Deployment Strategy Summary
+
+**Created**: 2026-01-12
+**Purpose**: Quick reference for development vs production differences
+
+---
+
+## 🎯 Core Strategy: Hybrid Architecture
+
+GigLez supports **two deployment modes** with shared codebase:
+
+### Development Mode (Termux on Android)
+```bash
+GIGLEZ_MODE=development
+```
+- **Purpose**: Local wardriving with T-Embed hardware
+- **Hardware**: USB serial + GPS access
+- **Users**: Single user
+- **Storage**: Local filesystem
+- **Auth**: Optional
+- **Database**: Local PostgreSQL (small pool: 5+5)
+- **API**: localhost:8000
+- **Background**: Synchronous processing
+
+### Production Mode (Server/VPS)
+```bash
+GIGLEZ_MODE=production
+```
+- **Purpose**: Public multi-user platform
+- **Hardware**: None (file uploads only)
+- **Users**: Multi-user with authentication
+- **Storage**: S3/MinIO object storage
+- **Auth**: Required (JWT + API keys)
+- **Database**: Remote PostgreSQL (large pool: 20+40)
+- **API**: Public HTTPS with reverse proxy
+- **Background**: Celery async tasks
+
+---

+# GigLez Implementation Plan - Post Wigle Analysis
+
+**Date**: 2026-01-12
+**Status**: Ready to Implement
+**Based on**: Wigle.net 15+ years of proven wardriving infrastructure
+
+---
+
+## Executive Summary
+
+We've completed a comprehensive analysis of Wigle.net's infrastructure, including:
+- Technology stack (MySQL/MariaDB, ElasticSearch, custom mapping)
+- Android client source code analysis (database schema, upload mechanisms, GPS handling)
+- API documentation (authentication, CSV format, rate limiting)
+- Architectural patterns (deduplication, performance optimizations, session management)
+
+**Key Finding**: Wigle has successfully scaled to **349M WiFi networks** and **billions of observations** using proven patterns we can adapt for GigLez's IoT RF device mapping.
+
+---
+
+## Current State Assessment
+
+### ✅ Completed
+- Project architecture and documentation (CLAUDE.md)
+- Database schema design (docs/database_schema.md)
+- .sub file parser implementation (src/parser/sub_parser.py)
+- Signature matching engine foundation (src/matcher/engine.py)
+- Wigle infrastructure analysis (docs/wigle_analysis.md)
+- Architecture decisions (docs/architecture_decisions.md)
+
+### 🚧 In Progress
+- None (ready to start implementation)
+
+### ❌ Not Started
+- PostgreSQL database setup
+- SQLAlchemy ORM models
+- FastAPI endpoints
+- Web interface
+- Signature database imports
+
+---
+
+## Wigle Analysis Key Takeaways
+
+### 1. Database Architecture
+
+**Wigle's Approach** (SQLite 3-table design):
+```
+network (BSSID primary key) → Core entity storage
+location (observations)      → Many-to-one with network
+route (GPS tracks)           → Independent session tracking
+```
+
+**GigLez Adaptation** (PostgreSQL + PostGIS):
+```
+captures (file_hash primary key) → .sub file + GPS
+capture_matches (many-to-many)   → Device identification results
+devices (reference data)         → Known device signatures
+sessions (run_id equivalent)     → Wardriving sessions
+```
+
+**Why Different**:
+- Wigle: BSSID is a natural unique identifier (MAC address)
+- GigLez: SHA256 file hash ensures deduplication of .sub files
+- Wigle: Observation-level GPS (one per scan)
+- GigLez: File-level GPS (one per .sub file)
+
+### 2. Deduplication Strategy
+
+**Wigle's Multi-Level Approach**:
+1. **Primary key**: BSSID prevents duplicate networks
+2. **Upload markers**: Track last uploaded ID per user
+3. **Spatial/temporal**: Filter observations within 100m and 24h
+4. **Network-level**: Update existing records instead of duplicating
+
+**GigLez Implementation**:
+```python
+# Primary deduplication (database level)
+file_hash = sha256(file_contents)  # Primary key
+
+# Spatial/temporal deduplication (optional)
+existing = query_captures_within(
+    latitude=lat,
+    longitude=lon,
+    radius_meters=50,
+    time_window_hours=1
+)
+
+# Upload markers (incremental sync)
+last_uploaded_id = get_user_marker(user_id, session_id)
+new_captures = filter_captures_after(last_uploaded_id)
+```
+
+### 3. GPS Handling
+
+**Wigle's Quality Checks**:
+- Minimum accuracy threshold: 32 meters
+- Null Island detection: (0.0, 0.0) rejected
+- Multi-provider fallback: GPS → Network → Last known
+- Location interpolation: Fill gaps between observations
+- Kalman filtering: Smooth noisy GPS tracks
+
+**GigLez GPS Validation** (from wigle_analysis.md):
+```python
+def validate_gps(lat: float, lon: float, accuracy: float) -> bool:
+    # Bounds check
+    if not (-90 <= lat <= 90 and -180 <= lon <= 180):
+        return False
+
+    # Null Island check
+    if abs(lat) < 0.001 and abs(lon) < 0.001:
+        return False
+
+    # Accuracy threshold
+    if accuracy > 50:  # meters
+        return False
+
+    return True
+```
+
+### 4. Upload System
+
+**Wigle CSV Format**:
+```csv
+WigleWifi-1.6,appRelease=2.70,model=Pixel,release=13,device=blueline,...
+MAC,SSID,AuthMode,FirstSeen,Channel,Frequency,RSSI,CurrentLatitude,CurrentLongitude,...
+00:11:22:33:44:55,MyNetwork,WPA2,2026-01-12 10:00:00,6,2437,-65,40.7128,-74.0060,...
+```
+
+**GigLez JSON + Binary Format**:
+```json
+{
+  "version": "GigLez-1.0",
+  "session_id": "550e8400-e29b-41d4-a716-446655440000",
+  "device_info": {
+    "model": "LilyGo T-Embed",
+    "firmware": "Bruce-2.1",
+    "app_version": "1.0.0"
+  },
+  "captures": [
+    {
+      "filename": "capture_001.sub",
+      "sha256": "abc123...",
+      "latitude": 40.7128,
+      "longitude": -74.0060,
+      "accuracy": 5.0,
+      "altitude": 10.5,
+      "timestamp": "2026-01-12T10:00:00Z"
+    }
+  ]
+}
+```
+
+### 5. Performance Optimizations
+
+**Wigle's Proven Patterns**:
+- Transaction batching (512 operations per commit)
+- Prepared statements (avoid SQL parsing overhead)
+- LRU caching (256 entries for device lookups)
+- Background threading (offload DB writes)
+- Pragma optimizations (temp_store=MEMORY, journal_mode=PERSIST)
+
+**GigLez Adaptations**:
+```python
+# Transaction batching (PostgreSQL)
+with db.begin():
+    for i in range(0, len(captures), 512):
+        batch = captures[i:i+512]
+        db.bulk_insert_mappings(Capture, batch)
+
+# LRU caching (device signatures)
+from functools import lru_cache
+
+@lru_cache(maxsize=256)
+def get_device_signature(device_id: int):
+    return db.query(Device).filter_by(id=device_id).first()
+
+# Async background tasks (FastAPI)
+from fastapi import BackgroundTasks
+
+@app.post("/api/captures")
+async def upload_captures(files: List[UploadFile], background: BackgroundTasks):
+    background.add_task(process_captures, files)
+    return {"status": "processing"}
+```

+## Risk Mitigation
+
+### Technical Risks
+1. **Database size growth**: Implement archival strategy, compress old captures
+2. **Query performance**: Add indexes, use materialized views, implement caching
+3. **File storage limits**: Use object storage (S3/MinIO) for .sub files
+4. **GPS accuracy**: Follow Wigle's validation patterns (32m threshold)
+
+### Implementation Risks
+1. **Scope creep**: Focus on MVP first (upload → parse → match → visualize)
+2. **Over-engineering**: Start simple, optimize when needed (measure first)
+3. **Signature database maintenance**: Automate imports with scripts
+
+---
+
+**Next Action**: Start Phase 1 database setup (PostgreSQL + PostGIS installation)

+**Purpose**: Phase 1 completion summary
+
+---
+
+## 🏗️ Architecture Highlights
+
+### Wigle Patterns Implemented
+
+1. **3-Table Design**
+   - `captures` (entity storage) → Primary RF file data
+   - `capture_matches` (observations) → Device identifications
+   - `sessions` (GPS tracks) → Wardriving sessions
+
+2. **SHA256 Primary Key**
+   - Automatic deduplication at database level
+   - Cryptographically strong uniqueness
+   - No application-level dedup logic needed
+
+3. **Upload Markers**
+   - Track last uploaded capture per user/session
+   - Enable incremental sync
+   - Resume after failed uploads
+
+4. **PostGIS Integration**
+   - GIST indexes for spatial queries
+   - Automatic geometry population (triggers)
+   - Efficient radius and bounding box queries
+
+5. **Performance Optimizations**
+   - Connection pooling (10 + 20 overflow)
+   - Materialized views for statistics
+   - Pre-ping connection validation
+   - Transaction batching support (512 ops)
+
+### Key Design Decisions
+
+#### 1. PostgreSQL + PostGIS (vs SQLite)
+**Reason**: Better geospatial query performance, ACID guarantees, multi-user support
+
+#### 2. SHA256 Hash Primary Key (vs Auto-increment ID)
+**Reason**: Automatic deduplication, content-based addressing
+
+#### 3. Separate Matches Table (vs Single Device Reference)
+**Reason**: Support multiple device matches per capture with confidence scores
+
+#### 4. Materialized Views (vs Real-time Queries)
+**Reason**: Pre-compute expensive aggregations for dashboard performance
+
+#### 5. Trigger-based Statistics (vs Application Updates)
+**Reason**: Guaranteed consistency, no application-level logic needed

+2. **Environment Awareness** - Settings-based feature flags
+3. **Optional Authentication** - Required in prod, optional in dev
+4. **Middleware Stack** - CORS, GZip, timing, logging
+5. **Error Handling** - Debug vs production error messages
+6. **Lifespan Management** - Startup validation, graceful shutdown
+
+---
+
+## 🚀 How to Test (Current Implementation)
+
+### 1. Install Dependencies
+```bash
+cd /home/dell/coding/giglez
+pip install -r requirements.txt
+pip install python-multipart  # For file uploads
+```
+
+### 2. Setup Database (if not done)
+```bash
+./scripts/setup_database.sh
+psql -U giglez_user -d giglez -h localhost -f scripts/create_schema.sql
+```
+
+### 3. Configure Environment
+```bash
+# Use development environment
+cp .env.development .env
+
+# Test configuration
+python config/settings.py
+```
+
+### 4. Start API Server
+```bash
+# Development mode with auto-reload
+python src/api/main.py
+
+# Or with uvicorn directly
+uvicorn src.api.main:app --host 127.0.0.1 --port 8000 --reload
+```
+
+### 5. Test Endpoints
+```bash
+# Health check
+curl http://localhost:8000/health
+
+# API info
+curl http://localhost:8000/
+
+# OpenAPI docs
+open http://localhost:8000/docs
+```
+
+### 6. Test Upload (Manual)
+```bash
+# Create test manifest
+cat > manifest.json << 'EOF'
+{
+    "session_uuid": "test-session-001",
+    "captures": [
+        {
+            "filename": "test.sub",
+            "latitude": 40.7128,
+            "longitude": -74.0060,
+            "accuracy": 5.0,
+            "timestamp": "2026-01-12T10:00:00Z"
+        }
+    ]
+}
+EOF
+
+# Create test .sub file (minimal)
+cat > test.sub << 'EOF'
+Filetype: Flipper SubGhz Key File
+Version: 1
+Frequency: 433920000
+Preset: FuriHalSubGhzPresetOok270Async
+Protocol: Princeton
+Bit: 24
+Key: 00 00 00 00 00 95 D5 D4
+EOF
+
+# Upload
+curl -X POST http://localhost:8000/api/v1/captures/upload \
+  -F "manifest=@manifest.json" \
+  -F "files=@test.sub"
+```
+

+
+## 📝 Next Session Plan
+
+### Priority 1: Authentication
+1. Create `src/api/auth.py`
+2. Implement JWT token generation
+3. Implement token validation
+4. Add login endpoint
+5. Update dependencies.py with real JWT decoding
+6. Test authentication flow
+
+### Priority 2: Background Tasks
+1. Create `src/api/tasks.py`
+2. Implement sync/Celery abstraction
+3. Add signature matching task
+4. Integrate with upload endpoint
+5. Test both modes
+
+### Priority 3: Query Endpoints
+1. Expand `src/api/routes/query.py`
+2. Implement geospatial queries (PostGIS)
+3. Add filtering and pagination
+4. Test performance
+
+---
+
+## 💡 Design Decisions Made
+
+### 1. Manifest in Form Data (vs Separate File)
+**Choice**: JSON string in form data
+**Reason**: Single POST request, no need for separate manifest file upload
+
+### 2. SHA256 Primary Key
+**Choice**: file_hash as primary key in Capture table
+**Reason**: Automatic deduplication at database level (Wigle pattern)
+
+### 3. Storage Path Sharding
+**Choice**: ab/c1/abc123...sub (first 2+2 chars)
+**Reason**: Prevents too many files in single directory (filesystem limits)
+
+### 4. Temporary File for Parsing
+**Choice**: Write to temp file before parsing
+**Reason**: Existing parser expects file path, not bytes
+
+### 5. Batch Commit
+**Choice**: Commit all captures after loop
+**Reason**: Atomicity - all or nothing (can be optimized later with batch size)
+
+---
+
+## 🔧 Technical Debt
+
+### Items to Address Later
+1. **Batch Size**: Currently commits all at once, should use 512-batch pattern
+2. **Parser Interface**: Should accept bytes directly, not file path
+3. **Error Recovery**: Partial uploads not resumable (need upload markers)
+4. **File Validation**: Should validate .sub format before parsing
+5. **Response Size**: Large uploads return large responses (consider streaming)
+6. **Async Storage**: Storage operations are sync (could be async)
+

+### 5. First Capture (Day 5)
+- Integrate all components
+- Capture real signal with GPS
+- Store in database
+- Verify data integrity
+
+## Known Challenges
+
+### Technical
+1. **Battery Life**: Continuous GPS + RF scanning drains battery quickly
+   - Solution: Implement duty cycling, power management
+2. **Serial Reliability**: USB serial can disconnect on Android
+   - Solution: Auto-reconnect logic, connection monitoring
+3. **Database Size**: Raw captures can grow large quickly
+   - Solution: Compression, selective storage, archival strategy
+
+### Hardware
+1. **CC1101 Frequency Gaps**: Can't cover entire spectrum
+   - 300-348, 387-464, 779-928 MHz only
+2. **Antenna Tuning**: Different frequencies need different antennas
+   - Solution: Multi-band antenna or frequency-specific sessions
+
+### Community
+1. **Verification Quality**: User-submitted IDs may be incorrect
+   - Solution: Multi-voter verification, reputation system
+2. **Privacy**: GPS coordinates could reveal home locations
+   - Solution: Anonymization options, GPS precision controls
+
+## Resources Needed
+
+### Development
+- [ ] Termux on Android with USB OTG support
+- [ ] LilyGo T-Embed CC1101 device
+- [ ] SD card (16GB+) for T-Embed
+- [ ] Multi-band sub-GHz antenna
+
+### Testing
+- [ ] Known devices for validation (garage remote, car key fob, etc.)
+- [ ] RTL-SDR for signal verification (optional)
+
+## Success Metrics
+
+### Phase 1 Complete When:
+- ✅ Database schema created and tested

+# GigLez - IoT RF Device Mapping Platform
+
+A Wigle.net-inspired crowdsourced platform for mapping and identifying Sub-GHz IoT RF devices.
+
+## Overview
+
+GigLez is a **platform-agnostic** web service that accepts .sub/.fff file uploads with GPS coordinates, automatically identifies IoT devices using signature databases, and visualizes device distribution on interactive maps. Think of it as Wigle.net for RF IoT devices instead of WiFi networks.
+
+**Key Principle**: We don't care what hardware you use to capture signals. If you can generate .sub files with GPS coordinates, you can contribute to the platform.
+
+## Features
+
+### Core Platform Features
+- **File Upload**: Submit .sub/.fff files with GPS coordinates via web or API
+- **Automatic Parsing**: Extract frequency, protocol, modulation, and timing from files
+- **Device Identification**: Match against 1000+ known signatures (Flipper Zero, RTL_433)
+- **Interactive Maps**: Visualize captured devices with heatmaps and clustering
+- **Search & Filter**: Query by location, device type, frequency, protocol
+- **Anonymous Uploads**: No account required (but optional for tracking contributions)
+
+### Community Features
+- **Manual Identification**: Add or correct device IDs with photo evidence
+- **Voting System**: Upvote/downvote community identifications
+- **Verification**: Earn reputation for accurate identifications
+- **Leaderboards**: Track top contributors
+- **Data Export**: Download captures as .sub, JSON, CSV, or GeoJSON
+
+## How It Works
+
+```

+# Project Refocus Summary
+
+**Date**: 2025-01-11
+**Major Pivot**: Hardware-specific → Platform-agnostic approach
+
+## What Changed
+
+### Before: Device-Dependent Architecture
+- Focused on LilyGo T-Embed integration
+- Termux + Android GPS as primary setup
+- Serial communication protocols
+- Hardware-specific capture workflow
+
+### After: Platform-Agnostic Web Service
+- **Accept uploads from ANY capture device**
+- .sub/.fff file submission with GPS coordinates
+- Web platform like Wigle.net
+- Focus on parsing, matching, and visualization
+
+## Key Principle
+
+> **We don't care what hardware you use.** If you can generate .sub files with GPS coordinates, you can contribute to GigLez.
+
+## Core Platform Features
+
+### 1. File Upload System
+- **Input**: .sub/.fff files + GPS coordinates
+- **Submission Methods**:
+  - Web drag-and-drop interface
+  - REST API (`POST /api/submit`)
+  - Batch uploads (ZIP + manifest.json)
+- **Anonymous or Authenticated**: User's choice
+
+### 2. Automatic Device Identification
+
+#### .sub File Parser (`src/parser/`)
+Extracts metadata from Flipper Zero .sub files:
+- Frequency, protocol, modulation
+- Bit length, key data, timing
+- RAW signal data (timing arrays)
+- Custom preset configurations
+
+**Files Created:**
+- `src/parser/metadata.py` - Data structures for signal metadata
+- `src/parser/sub_parser.py` - Complete .sub file parser with validation
+
+#### Signature Matching Engine (`src/matcher/`)
+Multi-strategy matching against known devices:
+
+1. **ExactMatcher** (100% confidence)
+   - Protocol + Frequency + Bit Length
+
+2. **PartialMatcher** (80% confidence)
+   - Protocol + Frequency only
+
+3. **PatternMatcher** (70-90% confidence)
+   - Bit pattern similarity with masks
+   - Hamming distance calculations
+
+4. **TimingMatcher** (60-80% confidence)
+   - Pulse timing characteristics from RAW files
+   - Average pulse width matching
+
+5. **FrequencyMatcher** (50-70% confidence)
+   - Fuzzy frequency matching within tolerance
+
+**Files Created:**
+- `src/matcher/engine.py` - Main matching coordinator
+- `src/matcher/strategies.py` - All matching strategy implementations
+
+### 3. Wigle.net-Inspired Platform
+
+#### Analyzed Features
+
+| Wigle.net Feature | GigLez Implementation |
+|-------------------|----------------------|
+| CSV upload format | .sub file upload + GPS JSON/CSV |
+| 349M+ WiFi networks | Start with IoT RF devices |
+| Text search (SSID/MAC) | Search by device type/protocol |
+| Geographic bounding box | PostGIS geospatial queries |
+| Heatmap visualization | Device density by location |
+| User leaderboards | Contribution tracking + reputation |
+| API access | RESTful JSON API |
+
+#### Key Differences
+
+- **Wigle**: Exact identification (MAC address = unique)
+- **GigLez**: Fuzzy matching (signal patterns → likely device)
+
+- **Wigle**: Public by default
+- **GigLez**: Opt-in sharing, anonymization options
+
+## Documentation Updates
+
+### CLAUDE.md (Primary Directive)
+Complete rewrite focusing on:
+- Platform-agnostic submission workflow
+- Wigle.net analysis and implementation strategy
+- .sub file parsing and matching pipeline
+- System architecture diagram
+- Submission API format specs
+
+**Removed**: All T-Embed/Termux/hardware-specific references

+# Returns: SignalMetadata with frequency, protocol, modulation, etc.
+```
+
+**Features**:
+- Handles KEY, RAW, and BinRAW formats
+- Extracts timing patterns from RAW files
+- Validates file structure
+- Error collection and reporting
+
+#### 2. Signature Matching Engine
+```python
+from src.matcher import SignatureMatcher
+
+matcher = SignatureMatcher(database)
+matcher.add_strategy(ExactMatcher())
+matcher.add_strategy(PartialMatcher())
+matcher.add_strategy(PatternMatcher())
+
+matches = matcher.match(metadata, max_results=10)
+# Returns: List[MatchResult] with confidence scores
+```
+
+**Features**:
+- Pluggable strategy pattern
+- Automatic deduplication
+- Confidence-based sorting
+- Detailed match explanations
+
+### Database Schema (Already Complete)
+- `captures` - RF captures with GPS

+# GigLez Architecture Decisions (Based on Wigle Analysis)
+
+## Overview
+
+This document captures key architectural decisions for GigLez, informed by analysis of the Wigle Android wardriving client.
+
+**Date**: 2026-01-12
+**Status**: Proposed
+**Source**: Wigle Analysis (/docs/wigle_analysis.md)
+
+---
+
+## Decision 1: Database Schema - PostgreSQL with PostGIS
+
+**Context**: Need to store millions of RF captures with GPS coordinates for geospatial queries.
+
+**Decision**: Use PostgreSQL + PostGIS with a 3-table structure:
+- `captures` - Primary RF file data (like Wigle's `network` table)
+- `capture_matches` - Device identification results (like Wigle's `location` table)
+- `devices` - Known device signature database (reference data)
+
+**Rationale**:
+- Wigle's 3-table design (network/location/route) has scaled to **349M WiFi networks** and **billions of observations**
+- PostGIS provides efficient geospatial indexing for radius/bounding box queries
+- Separate matches table allows many-to-many relationships (one capture → multiple device matches)
+
+**Alternatives Considered**:
+- MongoDB: No ACID guarantees, weaker geospatial query performance
+- Single table: Would duplicate device info, slower queries
+
+**Implementation**:
+```sql
+CREATE TABLE captures (
+    file_hash text primary key,
+    latitude double precision not null,
+    longitude double precision not null,
+    geom geometry(Point, 4326),  -- PostGIS spatial index
+    timestamp bigint not null,
+    frequency integer not null,
+    protocol text,
+    session_id text
+);
+CREATE INDEX idx_captures_geom ON captures USING GIST(geom);
+```
+
+---
+
+## Decision 2: File Deduplication - SHA256 Hash as Primary Key
+
+**Context**: Prevent duplicate .sub file submissions (same file uploaded multiple times).
+
+**Decision**: Use SHA256 hash of file contents as primary key in `captures` table.
+
+**Rationale**:
+- Wigle uses BSSID (MAC address) as primary key for natural deduplication
+- SHA256 provides **cryptographically strong** uniqueness guarantee
+- Automatic deduplication at database level (INSERT fails on duplicate)
+- No need for separate deduplication logic
+
+**Alternatives Considered**:
+- Auto-increment ID + separate hash check: More complex, requires application-level logic
+- GPS + timestamp composite key: Could have legitimate duplicates
+
+**Implementation**:
+```python
+import hashlib
+
+def compute_file_hash(file_path: str) -> str:
+    sha256 = hashlib.sha256()
+    with open(file_path, 'rb') as f:
+        for chunk in iter(lambda: f.read(8192), b''):
+            sha256.update(chunk)
+    return sha256.hexdigest()
+```
+
+---
+
+## Decision 3: Upload Format - JSON Manifest + Binary Files
+
+**Context**: Need to upload .sub files with GPS metadata to server.
+
+**Decision**: Use multipart/form-data with:
+- JSON manifest (GPS coordinates, metadata)
+- Binary .sub files (unmodified)
+
+**Rationale**:
+- Wigle uses CSV for structured data export - works for text but not binary files
+- JSON provides structured metadata (per-file GPS, session info)
+- Binary files preserve exact capture data (no encoding issues)
+- Supports batch uploads naturally (multiple files in one request)
+
+**Alternatives Considered**:
+- CSV with base64-encoded files: Bloated (33% overhead), parsing complexity
+- Separate API calls per file: Network inefficiency, no atomic batch
+
+**Implementation**:
+```json
+{
+  "version": "GigLez-1.0",
+  "session_id": "uuid",
+  "captures": [
+    {
+      "file": "capture_001.sub",
+      "sha256": "abc123...",
+      "gps": {
+        "latitude": 40.7128,
+        "longitude": -74.0060,
+        "accuracy": 5.0,
+        "timestamp": "2025-01-11T20:30:00Z"
+      }
+    }
+  ]
+}
+```
+
+---
+
+## Decision 4: Background Processing - Async Task Queue
+
+**Context**: .sub file parsing and device matching are CPU-intensive operations.
+
+**Decision**: Use async background task queue (FastAPI BackgroundTasks or Celery/RQ) for:
+- File parsing
+- Device signature matching
+- Database writes
+
+**Rationale**:
+- Wigle uses **background thread** for all database writes (THREAD_PRIORITY_BACKGROUND)
+- Prevents API timeouts on large uploads
+- Enables **immediate response** to user (202 Accepted)
+- Allows **horizontal scaling** of workers
+
+**Alternatives Considered**:
+- Synchronous processing: Slow, API timeouts on large files
+- Lambda functions: Cold start overhead, cost at scale
+
+**Implementation**:
+```python
+from fastapi import BackgroundTasks
+
+@app.post("/api/submit")
+async def submit_capture(file: UploadFile, background_tasks: BackgroundTasks):
+    file_path = await save_upload(file)
+    task_id = uuid4()
+
+    background_tasks.add_task(
+        process_capture_pipeline,
+        file_path=file_path,
+        task_id=task_id
+    )
+
+    return {"status": "accepted", "task_id": str(task_id)}
+```
+
+---
+
+## Decision 5: GPS Validation - Multi-Level Checks
+
+**Context**: GPS coordinates can be invalid (null island, extreme accuracy, out of bounds).
+
+**Decision**: Implement Wigle's multi-level GPS validation:
+1. Bounds check (-90≤lat≤90, -180≤lon≤180)
+2. Accuracy threshold (reject if >100m)
+3. Null island check (reject lat=0, lon=0)
+4. Timestamp validation (reject if 0)
+
+**Rationale**:
+- Wigle's horribleGps() function filters out **GPS noise** from hardware bugs
+- Prevents database pollution with junk coordinates
+- 100m threshold balances accuracy vs. rejection rate
+
+**Alternatives Considered**:
+- Accept all GPS: Database pollution, poor map quality
+- Strict threshold (<10m): Too restrictive, rejects valid mobile captures
+
+**Implementation**:
+```python
+def validate_gps(lat, lon, accuracy=None, timestamp=None):
+    if not (-90 <= lat <= 90) or not (-180 <= lon <= 180):
+        raise ValueError("GPS out of bounds")
+    if accuracy and accuracy > 100:
+        raise ValueError(f"GPS accuracy too low: {accuracy}m")
+    if lat == 0.0 and lon == 0.0:
+        raise ValueError("GPS at null island")
+    if timestamp == 0:
+        raise ValueError("Invalid timestamp")
+```
+
+---
+
+## Decision 6: Upload Marker System - Incremental Sync
+
+**Context**: Users may upload same database multiple times (after adding new captures).
+
+**Decision**: Track last uploaded capture ID per user (like Wigle's PREF_DB_MARKER).
+
+**Rationale**:
+- Wigle's marker system enables **incremental sync** (only new data)
+- Prevents re-uploading entire database on each sync
+- Enables **resume after failure** (upload only remaining captures)
+
+**Alternatives Considered**:
+- Always upload all captures: Wasteful bandwidth, slow
+- Client-side tracking only: Lost on app reinstall
+
+**Implementation**:
+```python
+class UploadMarker(Base):
+    __tablename__ = 'upload_markers'
+    user_id = Column(String, primary_key=True)
+    last_uploaded_id = Column(Integer, default=0)
+    last_upload_time = Column(BigInteger)
+
+def get_unuploaded_captures(user_id):
+    marker = db.query(UploadMarker).filter_by(user_id=user_id).first()
+    last_id = marker.last_uploaded_id if marker else 0
+
+    return db.query(Capture).filter(
+        Capture.id > last_id,
+        Capture.uploaded == False
+    ).all()
+```
+
+---
+
+## Decision 7: Session Management - Run ID System
+
+**Context**: Group captures by wardriving session for batch operations and statistics.
+
+**Decision**: Add `session_id` to captures table (like Wigle's `run_id`).
+
+**Rationale**:
+- Wigle's run_id groups **route points** by wardriving session
+- Enables batch operations (upload session, view session stats)
+- Useful for statistics (captures per session, coverage area)
+- Supports partial uploads (session-by-session)
+
+**Alternatives Considered**:
+- No grouping: Hard to track wardriving runs, no batch operations
+- Timestamp-based grouping: Unreliable (gaps in time)
+
+**Implementation**:
+```sql
+CREATE TABLE sessions (
+    session_id text primary key,
+    user_id text not null,
+    start_time bigint not null,
+    end_time bigint,
+    capture_count integer default 0,
+    uploaded boolean default false
+);
+
+ALTER TABLE captures ADD COLUMN session_id text REFERENCES sessions(session_id);
+CREATE INDEX idx_captures_session ON captures(session_id);
+```
+
+---
+
+## Decision 8: Performance - Transaction Batching
+
+**Context**: Writing captures one-at-a-time is slow (disk I/O overhead).
+
+**Decision**: Batch database writes in transactions (up to 512 operations).
+
+**Rationale**:
+- Wigle batches up to **512 DB updates** per transaction
+- Reduces disk I/O by 100x+ (one fsync per batch vs. per operation)
+- Critical for write-heavy workloads (wardriving generates 1000s of observations)
+
+**Alternatives Considered**:
+- Individual transactions: 100x slower, disk thrashing
+- Larger batches (>1000): Increased memory, longer transaction locks
+
+**Implementation**:
+```python
+from sqlalchemy.orm import Session
+
+def batch_insert_captures(captures: List[Capture], batch_size=512):
+    session = Session()
+
+    for i in range(0, len(captures), batch_size):
+        batch = captures[i:i+batch_size]
+        session.bulk_insert_mappings(Capture, batch)
+        session.commit()  # One commit per batch
+```
+
+---
+
+## Decision 9: Caching - LRU Cache for Device Lookups
+
+**Context**: Device signature matching queries database frequently for same devices.
+
+**Decision**: Add LRU cache (64-256 entries) for device lookups.
+
+**Rationale**:
+- Wigle uses **64-entry LRU cache** for network lookups
+- Reduces database queries by 90%+ (most captures match known devices)
+- Small memory footprint (few KB per entry)
+
+**Alternatives Considered**:
+- No cache: Database bottleneck, slow matching
+- Redis cache: Overkill for simple lookups, adds network latency
+
+**Implementation**:
+```python
+from functools import lru_cache
+
+@lru_cache(maxsize=256)
+def get_device_by_id(device_id: int) -> Device:
+    return db.query(Device).filter_by(device_id=device_id).first()
+```
+
+---
+
+## Decision 10: API Authentication - JWT + API Keys
+
+**Context**: Need to authenticate users for uploads and API access.
+
+**Decision**: Support both JWT tokens (web) and API keys (scripts/tools).
+
+**Rationale**:
+- Wigle uses **basic auth with API tokens** (retrieved via username/password)
+- JWT for web sessions (short-lived, stateless)
+- API keys for CLI tools (long-lived, revocable)
+- Flexible for different use cases
+
+**Alternatives Considered**:
+- Username/password only: Insecure for API, no token revocation
+- OAuth only: Overkill for simple use cases
+
+**Implementation**:
+```python
+from fastapi import Depends, HTTPException
+from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
+
+security = HTTPBearer()
+
+def get_current_user(credentials: HTTPAuthorizationCredentials = Depends(security)):
+    token = credentials.credentials
+
+    # Try JWT first
+    try:
+        payload = jwt.decode(token, SECRET_KEY, algorithms=["HS256"])
+        return payload["user_id"]
+    except:
+        pass
+
+    # Try API key
+    user = db.query(User).filter_by(api_key=token).first()
+    if user:
+        return user.user_id
+
+    raise HTTPException(status_code=401, detail="Invalid authentication")
+```
+

+    .fields         = output_fields,
+};
+```
+
+### JSON Output Format
+
+RTL_433 outputs decoded data as JSON:

+  "id": 12345,
+  "channel": "A",
+  "battery_ok": 1,
+  "temperature_C": 22.5,
+  "humidity": 45,
+  "mic": "CRC"
+}
+```
+

+
+### Extracting Protocol Definitions
+
+#### Step 1: Extract from Source Code
+```bash
+cd signatures/rtl433
+git clone --depth 1 https://github.com/merbanan/rtl_433.git temp
+grep -r "r_device" temp/src/devices/*.c > protocols.txt
+rm -rf temp
+```
+
+#### Step 2: Parse Protocol Definitions
+```python
+import re
+import json
+
+def parse_rtl433_protocol(protocol_string):
+    """Extract protocol definition from C code"""
+    pattern = r'r_device\s+(\w+)\s*=\s*{([^}]+)}'
+    match = re.search(pattern, protocol_string, re.DOTALL)
+
+    if not match:
+        return None
+
+    name = match.group(1)
+    body = match.group(2)
+
+    # Extract fields
+    modulation = re.search(r'\.modulation\s*=\s*(\w+)', body)
+    short_width = re.search(r'\.short_width\s*=\s*(\d+)', body)
+    long_width = re.search(r'\.long_width\s*=\s*(\d+)', body)
+    model_name = re.search(r'\.name\s*=\s*"([^"]+)"', body)
+
+    return {
+        'protocol_name': name,
+        'model': model_name.group(1) if model_name else None,
+        'modulation': modulation.group(1) if modulation else None,
+        'short_width': int(short_width.group(1)) if short_width else None,
+        'long_width': int(long_width.group(1)) if long_width else None
+    }
+```
+
+#### Step 3: Generate Protocol Database
+```python
+# Read all protocol definitions
+protocols = []
+for c_file in Path('temp/src/devices').glob('*.c'):
+    with open(c_file, 'r') as f:
+        content = f.read()
+        parsed = parse_rtl433_protocol(content)
+        if parsed:
+            protocols.append(parsed)
+
+# Save as JSON
+with open('signatures/rtl433/protocols.json', 'w') as f:
+    json.dump(protocols, f, indent=2)
+```
+
+### Using rtl_433 Test Data
+
+RTL_433 provides test signals with expected JSON output:
+
+```bash
+# Clone test repository
+git clone https://github.com/merbanan/rtl_433_tests.git signatures/rtl433/tests
+
+# Test files are organized as:
+# rtl_433_tests/tests/{protocol_name}/{signal_type}/*.cu8
+# rtl_433_tests/tests/{protocol_name}/{signal_type}/*.json
+```
+
+Example test data structure:
+```
+rtl_433_tests/tests/acurite/01/
+├── g001_433.92M_250k.cu8  # Raw signal capture
+└── g001_433.92M_250k.json # Expected decoded output
+```
+
+### Importing RTL_433 Signatures
+
+```python
+def import_rtl433_protocol(protocol_data, device_id):
+    """Import RTL_433 protocol to database"""
+    # Determine frequency from modulation
+    frequency_map = {
+        'OOK': 433920000,
+        'FSK': 868000000  # Varies by device
+    }
+
+    modulation_type = protocol_data.get('modulation', 'OOK')
+    base_freq = frequency_map.get(modulation_type[:3], 433920000)
+
+    signature = {
+        'device_id': device_id,
+        'protocol': protocol_data.get('model'),
+        'frequency': base_freq,
+        'modulation': modulation_type,
+        'timing_min': protocol_data.get('short_width'),
+        'timing_max': protocol_data.get('long_width'),
+        'source': 'rtl433',
+        'source_file': protocol_data.get('source_file')
+    }
+
+    # Insert into rtl433_protocols table
+    db.rtl433_protocols.insert({
+        'protocol_name': protocol_data.get('protocol_name'),
+        'model': protocol_data.get('model'),
+        'modulation': modulation_type,
+        'short_width': protocol_data.get('short_width'),
+        'long_width': protocol_data.get('long_width'),
+        'json_fields': protocol_data.get('fields', {})
+    })
+
+    # Also create general signature
+    db.signatures.insert(signature)
+```
+
+## 3. Universal Radio Hacker (URH)
+
+### Source
+- **Repository**: https://github.com/jopohl/urh
+- **Format**: `.urh` project files, `.complex` signal files
+
+### Signal File Formats
+
+#### .complex Files
+Raw I/Q signal data in binary format:
+- Interleaved I and Q samples
+- Typically 32-bit float or 8-bit integer
+- Sample rate metadata in accompanying .cfl file
+
+#### .urh Project Files
+XML-based project containing:
+- Signal definitions
+- Demodulation parameters
+- Protocol structure
+- Labeled message fields
+
+### Extracting URH Protocols
+
+URH projects often contain valuable protocol information in the community wiki.
+
+```bash
+# Download community-shared URH projects
+cd signatures/urh
+# Check URH GitHub wiki for shared project links
+```
+
+## 4. Community Signatures
+
+### User Submission Format
+
+When users identify a device, they can submit:
+
+```json
+{
+  "device": {
+    "manufacturer": "Chamberlain",
+    "model": "KLIK3U-SS",
+    "type": "garage_door_opener",
+    "fcc_id": "K49KLIK3U"
+  },
+  "signature": {
+    "frequency": 433920000,
+    "protocol": "Security+ 2.0",
+    "modulation": "OOK",
+    "notes": "Rolling code, 3-button remote"
+  },
+  "evidence": {
+    "photos": ["device_front.jpg", "device_back.jpg", "fcc_label.jpg"],
+    "capture_file": "chamberlain_klik3u_001.sub"
+  },
+  "location": {
+    "latitude": 40.7128,
+    "longitude": -74.0060,
+    "accuracy": 10
+  }
+}
+```
+
+### Verification Process
+
+1. User submits identification with photo evidence
+2. Community members vote (upvote/downvote)
+3. After 5 net upvotes, identification is auto-verified
+4. Verified identifications create new signature entries
+5. High-reputation users can verify immediately
+
+## 5. Signature Matching Algorithm
+
+### Matching Strategy
+
+```python
+def match_capture_to_signatures(capture):
+    """
+    Match a capture against known signatures

+        WHERE protocol = ? AND frequency = ? AND ? BETWEEN timing_min AND timing_max
+    ''', [capture.protocol, capture.frequency, capture.timing_element])
+    matches.extend(exact)
+
+    # Protocol + frequency match (80% confidence)

+            unique_matches[device_id] = conf
+
+    return sorted(unique_matches.items(), key=lambda x: x[1], reverse=True)
+```
+
+### Bit Pattern Matching
+
+```python
+def match_bit_pattern(key_data, signatures):
+    """
+    Match key data against signature patterns with masks
+    """
+    matches = []
+
+    for sig in signatures:

+        if masked_capture == masked_signature:
+            confidence = 0.9 * sig.weight
+            matches.append((sig.device_id, confidence))
+
+    return matches
+
+def apply_mask(data, mask):

+
+## Python Communication Library
+
+### Basic Usage
+
+```python
+import serial
+import json
+import time
+
+class TEmbedController:
+    def __init__(self, port='/dev/ttyUSB0', baudrate=115200):
+        self.serial = serial.Serial(port, baudrate, timeout=1)
+        self.request_id = 0

+            'params': params or {},
+            'id': self.request_id
+        }
+
+        # Send
+        self.serial.write(json.dumps(message).encode() + b'\n')
+
+        # Wait for response
+        line = self.serial.readline().decode().strip()
+        if line:

+
+device.listen_events(on_event)
+```
+
+### Async Implementation
+
+For better performance in production:
+
+```python
+import asyncio
+import aioserial
+
+class AsyncTEmbedController:
+    def __init__(self, port='/dev/ttyUSB0', baudrate=115200):
+        self.port = port
+        self.baudrate = baudrate
+        self.request_id = 0
+        self.pending_requests = {}
+
+    async def connect(self):
+        self.serial = aioserial.AioSerial(port=self.port, baudrate=self.baudrate)
+        await asyncio.sleep(2)
+
+    async def send_command(self, cmd, params=None):
+        self.request_id += 1
+        message = {
+            'cmd': cmd,
+            'params': params or {},
+            'id': self.request_id
+        }
+
+        # Send
+        await self.serial.write_async(json.dumps(message).encode() + b'\n')
+
+        # Create future for response
+        future = asyncio.Future()
+        self.pending_requests[self.request_id] = future
+
+        return await future
+
+    async def listen(self, event_callback):
+        """Background task to listen for responses and events"""
+        while True:
+            line = await self.serial.readline_async()
+            if line:
+                try:
+                    data = json.loads(line.decode().strip())
+
+                    # Handle response
+                    if 'id' in data and data['id'] in self.pending_requests:
+                        self.pending_requests[data['id']].set_result(data)
+                        del self.pending_requests[data['id']]
+
+                    # Handle event
+                    elif 'event' in data:
+                        await event_callback(data)
+
+                except json.JSONDecodeError:
+                    pass
+```
+
+## GPS Coordination
+
+### Timestamp Synchronization
+
+The T-Embed doesn't have GPS, so timestamps come from Android:
+
+```python
+import time
+
+# Send timestamp to device
+device.send_command('CONFIG', {
+    'system_time': int(time.time())
+})
+
+# Device will use this to calibrate its internal clock
+```
+
+### Capture with GPS
+
+When a signal is captured, immediately tag it with GPS:
+
+```python
+import android
+from tembed import TEmbedController
+
+# Initialize Android SL4A for GPS
+droid = android.Android()
+droid.startLocating()
+
+# T-Embed controller
+device = TEmbedController()
+
+# Event handler
+async def on_signal(event):
+    if event['event'] == 'SIGNAL_DETECTED':
+        # Get current GPS location
+        location = droid.getLastKnownLocation().result
+        gps = location.get('gps') or location.get('network')
+
+        if gps:
+            # Store in database with GPS
+            store_capture({
+                'frequency': event['data']['frequency'],
+                'rssi': event['data']['rssi'],
+                'latitude': gps['latitude'],
+                'longitude': gps['longitude'],
+                'accuracy': gps.get('accuracy', 0),
+                'timestamp': event['data']['timestamp']
+            })
+
+# Start listening
+await device.listen(on_signal)
+```
+
+## Troubleshooting
+
+### Device Not Detected
+
+```bash
+# Check USB devices
+lsusb
+
+# Check serial ports
+ls -l /dev/ttyUSB* /dev/ttyACM*
+
+# Grant permissions (Termux)
+termux-usb -l  # List devices
+termux-usb -r /dev/bus/usb/XXX/YYY  # Request permission
+```
+
+### Serial Communication Errors
+
+```python
+# Add error handling
+try:
+    response = device.send_command('STATUS')
+except serial.SerialException as e:
+    print(f"Serial error: {e}")
+    # Attempt reconnection
+    device.serial.close()
+    device.serial.open()
+```
+
+### Firmware Update
+
+```bash
+# Backup SD card first
+adb pull /sdcard/giglez /path/to/backup
+
+# Flash new firmware
+esptool.py --chip esp32s3 --port /dev/ttyUSB0 erase_flash
+esptool.py --chip esp32s3 --port /dev/ttyUSB0 write_flash 0x0 firmware.bin
+```
+
+## Next Steps
+
+1. Flash Bruce firmware to T-Embed
+2. Test serial communication from Termux
+3. Implement capture coordination with GPS
+4. Build async event handling system
+5. Develop custom firmware optimized for GigLez
