CLAUDE: Migrate to technology-first documentation architecture

Complete restructure from patterns/examples/reference to technology-focused directories:

• Created technology-specific directories with comprehensive documentation:
  - /tdarr/ - Transcoding automation with gaming-aware scheduling
  - /docker/ - Container management with GPU acceleration patterns
  - /vm-management/ - Virtual machine automation and cloud-init
  - /networking/ - SSH infrastructure, reverse proxy, and security
  - /monitoring/ - System health checks and Discord notifications
  - /databases/ - Database patterns and troubleshooting
  - /development/ - Programming language patterns (bash, nodejs, python, vuejs)

• Enhanced CLAUDE.md with intelligent context loading:
  - Technology-first loading rules for automatic context provision
  - Troubleshooting keyword triggers for emergency scenarios
  - Documentation maintenance protocols with automated reminders
  - Context window management for optimal documentation updates

• Preserved valuable content from .claude/tmp/:
  - SSH security improvements and server inventory
  - Tdarr CIFS troubleshooting and Docker iptables solutions
  - Operational scripts with proper technology classification

• Benefits achieved:
  - Self-contained technology directories with complete context
  - Automatic loading of relevant documentation based on keywords
  - Emergency-ready troubleshooting with comprehensive guides
  - Scalable structure for future technology additions
  - Eliminated context bloat through targeted loading

+- **Documentation Maintenance Reminder**: At the end of coding sessions, proactively ask: "Should I update our documentation to reflect the changes we made today?" Focus on CONTEXT.md files, troubleshooting guides, and any new patterns discovered.
+- **Context Window Management**: When approaching 25% context window remaining, prioritize documentation updates before auto-summarization occurs. Ask: "We're approaching context limits - should I update our documentation now to capture today's work before we lose context?"

 ### Directory Usage Guidelines
 
-- `/scripts/` - Contains actively used scripts for home lab management and operations
+- Each technology directory is self-contained with its own context, troubleshooting, examples, and scripts
-  - Organized by subsystem (e.g., `tdarr/`, `networking/`, `vm-management/`)
+- `CONTEXT.md` files provide technology overview, patterns, and best practices for Claude
-  - Each subsystem includes its own README.md with complete documentation
+- `troubleshooting.md` files contain error handling and debugging information
-- `/examples/` - Contains example configurations and template scripts for reference
+- `/scripts/` subdirectories contain active operational code with their own `CONTEXT.md`
-- `/patterns/` - Best practices and architectural guidance  
+- `/examples/` subdirectories contain template configurations and reference implementations
-- `/reference/` - Troubleshooting guides and technical references
+- `/development/` contains general programming language patterns that apply across technologies
+- `/legacy/` provides backward compatibility during the migration from the old structure
+
+## Documentation Maintenance Protocol
+
+### Automated Maintenance Triggers
+Claude Code should automatically prompt for documentation updates when:
+
+1. **New Technology Integration**: When working with a technology that doesn't have a dedicated directory
+   - Prompt: "I notice we're working with [technology] but don't have a dedicated `/[technology]/` directory. Should I create the technology-first structure with CONTEXT.md and troubleshooting.md files?"
+
+2. **New Error Patterns Discovered**: When encountering and solving new issues
+   - Prompt: "We just resolved a [technology] issue that isn't documented. Should I add this solution to `[technology]/troubleshooting.md`?"
+
+3. **New Scripts or Operational Procedures**: When creating new automation or workflows
+   - Prompt: "I created new scripts/procedures for [technology]. Should I update `[technology]/scripts/CONTEXT.md` and add any new operational patterns?"
+
+4. **Session End with Significant Changes**: When completing complex tasks
+   - Prompt: "We made significant changes to [technology] systems. Should I update our documentation to reflect the new patterns, configurations, or troubleshooting procedures we discovered?"
+
+### Documentation Update Checklist
+When "update our documentation" is requested, systematically check:
+
+**Technology-Specific Updates**:
+- [ ] Update `[technology]/CONTEXT.md` with new patterns or architectural changes
+- [ ] Add new troubleshooting scenarios to `[technology]/troubleshooting.md`
+- [ ] Update `[technology]/scripts/CONTEXT.md` for new operational procedures
+- [ ] Add working examples to `[technology]/examples/` if new configurations were created
+
+**Cross-Technology Updates**:
+- [ ] Update main CLAUDE.md loading rules if new keywords or triggers are needed
+- [ ] Add new technology directories to the Documentation Structure section
+- [ ] Update Directory Usage Guidelines if new organizational patterns emerge
+
+**Legacy Cleanup**:
+- [ ] Check if any old patterns/examples/reference files can be migrated to technology directories
+- [ ] Update or remove outdated information that conflicts with new approaches
+
+### Self-Maintenance Features
+
+**Loading Rule Validation**: Periodically verify that:
+- All technology directories have corresponding keyword triggers
+- Troubleshooting keywords include all common error scenarios
+- File paths in loading rules match actual directory structure
+
+**Documentation Completeness Check**: Each technology directory should have:
+- `CONTEXT.md` (overview, patterns, best practices)
+- `troubleshooting.md` (error scenarios, emergency procedures)
+- `examples/` (working configurations)
+- `scripts/CONTEXT.md` (if operational scripts exist)
+
+**Keyword Coverage Analysis**: Ensure loading rules cover:
+- Technology names and common aliases
+- Error types and troubleshooting scenarios  
+- Operational keywords (start, stop, configure, monitor)
+- Emergency keywords (shutdown, reset, recovery)
+
+### Warning Triggers
+Claude Code should warn when:
+- Working extensively with a technology that lacks dedicated documentation structure
+- Solving problems that aren't covered in existing troubleshooting guides
+- Creating scripts or procedures without corresponding CONTEXT.md documentation
+- Encountering loading rules that reference non-existent files

+# Database Troubleshooting Guide
+
+## Connection Issues
+
+### Cannot Connect to Database
+**Symptoms**: Connection refused, timeout errors, authentication failures
+**Diagnosis**:
+```bash
+# Test basic connectivity
+telnet db-server 3306  # MySQL
+telnet db-server 5432  # PostgreSQL
+nc -zv db-server 6379  # Redis
+
+# Check database service status
+systemctl status mysql
+systemctl status postgresql
+systemctl status redis-server
+```
+
+**Solutions**:
+```bash
+# Restart database services
+sudo systemctl restart mysql
+sudo systemctl restart postgresql
+
+# Check configuration files
+sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
+sudo nano /etc/postgresql/*/main/postgresql.conf
+
+# Verify port bindings
+ss -tlnp | grep :3306  # MySQL
+ss -tlnp | grep :5432  # PostgreSQL
+```
+
+## Performance Issues
+
+### Slow Query Performance
+**Symptoms**: Long-running queries, high CPU usage, timeouts
+**Diagnosis**:
+```sql
+-- MySQL
+SHOW PROCESSLIST;
+SHOW ENGINE INNODB STATUS;
+EXPLAIN SELECT * FROM table WHERE condition;
+
+-- PostgreSQL  
+SELECT * FROM pg_stat_activity;
+EXPLAIN ANALYZE SELECT * FROM table WHERE condition;
+```
+
+**Solutions**:
+```sql
+-- Add missing indexes
+CREATE INDEX idx_column ON table(column);
+
+-- Analyze table statistics
+ANALYZE TABLE table_name;  -- MySQL
+ANALYZE table_name;        -- PostgreSQL
+
+-- Optimize queries
+-- Use LIMIT for large result sets
+-- Add WHERE clauses to filter results
+-- Use appropriate JOIN types
+```
+
+### Memory and Resource Issues
+**Symptoms**: Out of memory errors, swap usage, slow performance
+**Diagnosis**:
+```bash
+# Check memory usage
+free -h
+ps aux | grep mysql
+ps aux | grep postgres
+
+# Database-specific memory usage
+mysqladmin -u root -p status
+sudo -u postgres psql -c "SELECT * FROM pg_stat_database;"
+```
+
+**Solutions**:
+```bash
+# Adjust database memory settings
+# MySQL - /etc/mysql/mysql.conf.d/mysqld.cnf
+innodb_buffer_pool_size = 2G
+key_buffer_size = 256M
+
+# PostgreSQL - /etc/postgresql/*/main/postgresql.conf
+shared_buffers = 256MB
+effective_cache_size = 2GB
+work_mem = 4MB
+```
+
+## Data Integrity Issues
+
+### Corruption Detection and Recovery
+**Symptoms**: Table corruption errors, data inconsistencies
+**Diagnosis**:
+```sql
+-- MySQL
+CHECK TABLE table_name;
+mysqlcheck -u root -p --all-databases
+
+-- PostgreSQL
+-- Check for corruption in logs
+tail -f /var/log/postgresql/postgresql-*.log
+```
+
+**Solutions**:
+```sql
+-- MySQL table repair
+REPAIR TABLE table_name;
+mysqlcheck -u root -p --auto-repair database_name
+
+-- PostgreSQL consistency check
+-- Run VACUUM and REINDEX
+VACUUM FULL table_name;
+REINDEX TABLE table_name;
+```
+
+## Backup and Recovery Issues
+
+### Backup Failures
+**Symptoms**: Backup scripts failing, incomplete backups
+**Diagnosis**:
+```bash
+# Check backup script logs
+tail -f /var/log/backup.log
+
+# Test backup commands manually
+mysqldump -u root -p database_name > test_backup.sql
+pg_dump -U postgres database_name > test_backup.sql
+
+# Check disk space
+df -h /backup/location/
+```
+
+**Solutions**:
+```bash
+# Fix backup script permissions
+chmod +x /path/to/backup-script.sh
+chown backup-user:backup-group /backup/location/
+
+# Automated backup script example
+#!/bin/bash
+BACKUP_DIR="/backups/mysql"
+DATE=$(date +%Y%m%d_%H%M%S)
+
+mysqldump -u root -p$MYSQL_PASSWORD --all-databases > \
+    "$BACKUP_DIR/full_backup_$DATE.sql"
+
+# Compress and rotate backups
+gzip "$BACKUP_DIR/full_backup_$DATE.sql"
+find "$BACKUP_DIR" -name "*.gz" -mtime +7 -delete
+```
+
+## Authentication and Security Issues
+
+### Access Denied Errors
+**Symptoms**: Authentication failures, permission errors
+**Diagnosis**:
+```sql
+-- MySQL
+SELECT user, host FROM mysql.user;
+SHOW GRANTS FOR 'username'@'host';
+
+-- PostgreSQL
+\du  -- List users
+\l   -- List databases
+```
+
+**Solutions**:
+```sql
+-- MySQL user management
+CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
+GRANT ALL PRIVILEGES ON database.* TO 'newuser'@'localhost';
+FLUSH PRIVILEGES;
+
+-- PostgreSQL user management
+CREATE USER newuser WITH PASSWORD 'password';
+GRANT ALL PRIVILEGES ON DATABASE database_name TO newuser;
+```
+
+## Replication Issues
+
+### Master-Slave Replication Problems
+**Symptoms**: Replication lag, sync errors, slave disconnection
+**Diagnosis**:
+```sql
+-- MySQL Master
+SHOW MASTER STATUS;
+
+-- MySQL Slave
+SHOW SLAVE STATUS\G
+
+-- Check replication lag
+SELECT SECONDS_BEHIND_MASTER FROM SHOW SLAVE STATUS\G
+```
+
+**Solutions**:
+```sql
+-- Reset replication
+STOP SLAVE;
+RESET SLAVE;
+CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=4;
+START SLAVE;
+
+-- Fix replication errors
+SET GLOBAL sql_slave_skip_counter = 1;
+START SLAVE;
+```
+
+## Storage and Disk Issues
+
+### Disk Space Problems
+**Symptoms**: Out of disk space errors, database growth
+**Diagnosis**:
+```bash
+# Check database sizes
+du -sh /var/lib/mysql/*
+du -sh /var/lib/postgresql/*/main/*
+
+# Find large tables
+SELECT table_schema, table_name, 
+       ROUND((data_length + index_length) / 1024 / 1024, 2) AS 'Size (MB)'
+FROM information_schema.tables 
+ORDER BY (data_length + index_length) DESC;
+```
+
+**Solutions**:
+```sql
+-- Clean up large tables
+DELETE FROM log_table WHERE created_date < DATE_SUB(NOW(), INTERVAL 30 DAY);
+OPTIMIZE TABLE log_table;

+# Docker Container Technology - Technology Context
+
+## Overview
+Docker containerization for home lab environments with focus on performance optimization, GPU acceleration, and distributed workloads. This context covers container architecture patterns, security practices, and production deployment strategies.
+
+## Architecture Patterns
+
+### Container Design Principles
+1. **Single Responsibility**: One service per container
+2. **Immutable Infrastructure**: Treat containers as replaceable units
+3. **Resource Isolation**: Use container limits and cgroups
+4. **Security First**: Run as non-root, minimal attack surface
+5. **Configuration Management**: Environment variables and external configs
+
+### Multi-Stage Build Pattern
+**Purpose**: Minimize production image size and attack surface
+```dockerfile
+# Build stage
+FROM node:18 AS builder
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci --only=production
+
+# Production stage  
+FROM node:18-alpine AS production
+WORKDIR /app
+COPY --from=builder /app/node_modules ./node_modules
+COPY . .
+USER 1000
+EXPOSE 3000
+CMD ["node", "server.js"]
+```
+
+### Distributed Application Architecture
+**Pattern**: Server-Node separation with specialized workloads
+
+```
+┌─────────────────┐    ┌──────────────────────────────────┐
+│   Control Plane │    │        Worker Nodes              │
+│                 │    │  ┌─────────┐ ┌─────────┐         │
+│  - Web Interface│◄──►│  │ Node 1  │ │ Node 2  │ ...     │
+│  - Job Queue    │    │  │ GPU+CPU │ │ GPU+CPU │         │
+│  - Coordination │    │  │Local SSD│ │Local SSD│         │
+│                 │    │  └─────────┘ └─────────┘         │
+└─────────────────┘    └──────────────────────────────────┘
+         │                              │
+         └──────── Shared Storage ──────┘
+              (NAS/SAN for persistence)
+```
+
+## Container Runtime Platforms
+
+### Docker vs Podman Comparison
+**Docker**: Traditional daemon-based approach
+- Requires Docker daemon running as root
+- Centralized container management
+- Established ecosystem and tooling
+
+**Podman** (Recommended for GPU workloads):
+- Daemonless architecture
+- Better GPU integration with NVIDIA
+- Rootless containers for enhanced security
+- Direct systemd integration
+
+### GPU Acceleration Support
+**NVIDIA Container Toolkit Integration**:
+```bash
+# Podman GPU configuration (recommended)
+podman run -d --name gpu-workload \
+    --device nvidia.com/gpu=all \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    -e NVIDIA_VISIBLE_DEVICES=all \
+    myapp:latest
+
+# Docker GPU configuration
+docker run -d --name gpu-workload \
+    --gpus all \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    myapp:latest
+```
+
+## Performance Optimization Patterns
+
+### Hybrid Storage Strategy
+**Pattern**: Balance performance and persistence for different data types
+
+```yaml
+volumes:
+  # Local storage (SSD/NVMe) - High Performance
+  - ./app/data:/app/data              # Database - frequent I/O
+  - ./app/configs:/app/configs        # Config - startup performance
+  - ./app/logs:/app/logs              # Logs - continuous writing
+  - ./cache:/cache                    # Work directories - temp processing
+  
+  # Network storage (NAS) - Persistence & Backup  
+  - /mnt/nas/backups:/app/backups     # Backups - infrequent access
+  - /mnt/nas/media:/media:ro          # Source data - read-only
+```
+
+**Benefits**:
+- **Local Operations**: 100x faster database performance vs network
+- **Network Reliability**: Critical data protected on redundant storage
+- **Cost Optimization**: Expensive fast storage only where needed
+
+### Cache Optimization Hierarchy
+```bash
+# Performance tiers for different workload types
+/dev/shm/cache/          # RAM disk - fastest, volatile, limited size
+/mnt/nvme/cache/         # NVMe SSD - 3-7GB/s, persistent, recommended
+/mnt/ssd/cache/          # SATA SSD - 500MB/s, good balance
+/mnt/nas/cache/          # Network - 100MB/s, legacy compatibility
+```
+
+### Resource Management
+**Container Limits** (prevent resource exhaustion):
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 8G
+      cpus: '6'
+    reservations:
+      memory: 4G
+      cpus: '2'
+```
+
+**Networking Optimization**:
+```yaml
+# Host networking for performance-critical applications
+network_mode: host
+
+# Bridge networking with port mapping (default)
+network_mode: bridge
+ports:
+  - "8080:8080"
+```
+
+## Security Patterns
+
+### Container Hardening
+```dockerfile
+# Use minimal base images
+FROM alpine:3.18
+
+# Run as non-root user
+RUN addgroup -g 1000 appuser && \
+    adduser -u 1000 -G appuser -s /bin/sh -D appuser
+USER 1000
+
+# Set secure permissions
+COPY --chown=appuser:appuser . /app
+```
+
+### Environment Security
+```bash
+# Secrets management (avoid environment variables for secrets)
+podman secret create db_password password.txt
+podman run --secret db_password myapp:latest
+
+# Network isolation
+podman network create --driver bridge isolated-net
+podman run --network isolated-net myapp:latest
+```
+
+### Image Security
+1. **Vulnerability Scanning**: Regular image scans with tools like Trivy
+2. **Version Pinning**: Use specific tags, avoid `latest`
+3. **Minimal Images**: Distroless or Alpine base images
+4. **Layer Optimization**: Minimize layers, combine RUN commands
+
+## Development Workflows
+
+### Local Development Pattern
+```yaml
+# docker-compose.dev.yml
+version: "3.8"
+services:
+  app:
+    build: .
+    volumes:
+      - .:/app              # Code hot-reload
+      - /app/node_modules   # Preserve dependencies
+    environment:
+      - NODE_ENV=development
+    ports:
+      - "3000:3000"
+```
+
+### Production Deployment Pattern
+```bash
+# Production container with health checks
+podman run -d --name production-app \
+    --restart unless-stopped \
+    --health-cmd="curl -f http://localhost:3000/health || exit 1" \
+    --health-interval=30s \
+    --health-timeout=10s \
+    --health-retries=3 \
+    -p 3000:3000 \
+    myapp:v1.2.3
+```
+
+## Monitoring and Observability
+
+### Health Check Implementation
+```dockerfile
+# Application health check
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+    CMD curl -f http://localhost:3000/health || exit 1
+```
+
+### Log Management
+```bash
+# Structured logging with log rotation
+podman run -d --name app \
+    --log-driver journald \
+    --log-opt max-size=10m \
+    --log-opt max-file=3 \
+    myapp:latest
+
+# Centralized logging
+podman logs -f app | logger -t myapp
+```
+
+### Resource Monitoring
+```bash
+# Real-time container metrics
+podman stats --no-stream app
+
+# Historical resource usage
+podman exec app cat /sys/fs/cgroup/memory/memory.usage_in_bytes
+```
+
+## Common Implementation Patterns
+
+### Database Containers
+```yaml
+# Persistent database with backup strategy
+services:
+  postgres:
+    image: postgres:15-alpine
+    environment:
+      POSTGRES_DB: myapp
+      POSTGRES_USER: appuser
+      POSTGRES_PASSWORD_FILE: /run/secrets/db_password
+    volumes:
+      - postgres_data:/var/lib/postgresql/data  # Persistent data
+      - ./backups:/backups                      # Backup mount
+    secrets:
+      - db_password
+```
+
+### Web Application Containers
+```yaml
+# Multi-tier web application
+services:
+  frontend:
+    image: nginx:alpine
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf:ro
+    ports:
+      - "80:80"
+      - "443:443"
+    depends_on:
+      - backend
+      
+  backend:
+    build: ./api
+    environment:
+      - DATABASE_URL=postgresql://appuser@postgres/myapp
+    depends_on:
+      - postgres
+```
+
+### GPU-Accelerated Workloads
+```bash
+# GPU transcoding/processing container
+podman run -d --name gpu-processor \
+    --device nvidia.com/gpu=all \
+    -e NVIDIA_DRIVER_CAPABILITIES=compute,video \
+    -v "/fast-storage:/cache" \
+    -v "/media:/input:ro" \
+    -v "/output:/output" \
+    gpu-app:latest
+```
+
+## Best Practices
+
+### Production Deployment
+1. **Use specific image tags**: Never use `latest` in production
+2. **Implement health checks**: Application and infrastructure monitoring
+3. **Resource limits**: Prevent resource exhaustion
+4. **Backup strategy**: Regular backups of persistent data
+5. **Security scanning**: Regular vulnerability assessments
+
+### Development Guidelines
+1. **Multi-stage builds**: Separate build and runtime environments
+2. **Environment parity**: Keep dev/staging/prod similar
+3. **Configuration externalization**: Use environment variables and secrets
+4. **Dependency management**: Pin versions, use lock files
+5. **Testing strategy**: Unit, integration, and container tests
+
+### Operational Excellence
+1. **Log aggregation**: Centralized logging strategy
+2. **Metrics collection**: Application and infrastructure metrics
+3. **Alerting**: Proactive monitoring and alerting
+4. **Documentation**: Container documentation and runbooks
+5. **Disaster recovery**: Backup and recovery procedures
+
+## Migration Patterns
+
+### Legacy Application Containerization
+1. **Assessment**: Identify dependencies and requirements
+2. **Dockerfile creation**: Start with appropriate base image
+3. **Configuration externalization**: Move configs to environment variables
+4. **Data persistence**: Identify and volume mount data directories
+5. **Testing**: Validate functionality in containerized environment
+
+### Platform Migration (Docker to Podman)
+```bash
+# Export Docker container configuration
+docker inspect mycontainer > container-config.json
+
+# Convert to Podman run command
+podman run -d --name mycontainer \
+    --memory 4g \
+    --cpus 2 \
+    -v /host/path:/container/path \
+    myimage:tag
+```
+
+This technology context provides comprehensive guidance for implementing Docker containerization strategies in home lab and production environments.

+
+## Problem Summary
+Docker daemon fails to start with persistent error:
+```
+failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to register "bridge" driver: failed to create NAT chain DOCKER: COMMAND_FAILED: INVALID_IPV: 'ipv4' is not a valid backend or is unavailable
+```
+
+## Root Cause Analysis
+
+### Initial Discovery
+1. **Missing iptables**: Docker couldn't find `iptables` command in PATH
+2. **Backend conflict**: System using nftables but Docker expects iptables-legacy
+3. **Package inconsistency**: `iptables-nft` package installed but binary missing initially
+
+### Key Findings
+- `dnf list installed | grep -i iptables` initially returned nothing
+- `firewalld` and `nftables` services were both inactive
+- `iptables-nft` package was installed but `/usr/bin/iptables` didn't exist
+- After reinstall, iptables worked but used nftables backend
+- NAT table incompatible: `iptables v1.8.11 (nf_tables): table 'nat' is incompatible, use 'nft' tool.`
+
+## Troubleshooting Steps Performed
+
+### Step 1: Package Investigation
+```bash
+# Check installed iptables packages
+dnf list installed | grep -i iptables
+# Result: No matching packages (surprising!)
+
+# Check service status
+systemctl status nftables    # inactive (dead)
+firewall-cmd --get-backend-type  # firewalld not running
+
+# Check if iptables binary exists
+which iptables  # not found
+/usr/bin/iptables --version  # No such file or directory
+```
+
+### Step 2: Package Reinstallation
+```bash
+# Reinstall iptables-nft package
+sudo dnf reinstall -y iptables-nft
+
+# Verify installation
+rpm -ql iptables-nft | grep bin
+# Shows /usr/bin/iptables should exist
+
+# Test after reinstall
+iptables --version
+# Result: iptables v1.8.11 (nf_tables) - SUCCESS!
+```
+
+### Step 3: Backend Compatibility Testing
+```bash
+# Test NAT table access
+sudo iptables -t nat -L
+# Error: iptables v1.8.11 (nf_tables): table `nat' is incompatible, use 'nft' tool.
+```
+
+### Step 4: Legacy Backend Installation
+```bash
+# Install iptables-legacy
+sudo dnf install -y iptables-legacy iptables-legacy-libs
+
+# Set up alternatives system
+sudo alternatives --install /usr/bin/iptables iptables /usr/bin/iptables-legacy 10
+sudo alternatives --install /usr/bin/ip6tables ip6tables /usr/bin/ip6tables-legacy 10
+
+# Test NAT table with legacy backend
+sudo iptables -t nat -L
+# SUCCESS: Shows empty NAT chains
+```
+
+### Step 5: Docker Restart Attempts
+```bash
+# Remove NVIDIA daemon.json config (potential conflict)
+sudo rm -f /etc/docker/daemon.json
+
+# Load NAT kernel module explicitly
+sudo modprobe iptable_nat
+
+# Try starting firewalld (in case Docker needs it)
+sudo systemctl enable --now firewalld
+
+# Multiple restart attempts
+sudo systemctl start docker
+# ALL FAILED with same NAT chain error
+```
+
+## Current State
+- ✅ iptables-legacy installed and configured
+- ✅ NAT table accessible via `iptables -t nat -L`
+- ✅ All required kernel modules should be available
+- ❌ Docker still fails with NAT chain creation error
+- ❌ Same error persists despite backend switch
+
+## Analysis of Persistent Issue
+
+### Potential Causes
+1. **Kernel State Contamination**: nftables rules/chains may still be active in kernel memory
+2. **Module Loading Order**: iptables vs nftables modules loaded in conflicting order
+3. **Docker Caching**: Docker may be caching the old backend detection
+4. **Firewall Integration**: Docker + firewalld interaction on Fedora/Nobara
+5. **System-Level Backend Selection**: Some system-wide iptables backend lock
+
+### Evidence Supporting Kernel State Theory
+- Error message is identical across all restart attempts
+- iptables command works fine manually
+- NAT table shows properly but Docker can't create chains
+- Issue persists despite configuration changes
+
+## Next Session Action Plan
+
+### Immediate Steps After System Reboot
+1. **Verify Backend Status**:
+   ```bash
+   iptables --version  # Should show legacy
+   sudo iptables -t nat -L  # Should show clean NAT table
+   ```
+
+2. **Check Kernel Modules**:
+   ```bash
+   lsmod | grep -E "(iptable|nf_|ip_tables)"
+   modprobe -l | grep -E "(iptable|nf_table)"
+   ```
+
+3. **Test Docker Start**:
+   ```bash
+   sudo systemctl start docker
+   docker --version
+   ```
+
+### If Issue Persists After Reboot
+
+#### Alternative Approach 1: Docker Configuration Override
+```bash
+# Create daemon.json to disable iptables management
+sudo mkdir -p /etc/docker
+cat <<EOF | sudo tee /etc/docker/daemon.json
+{
+  "iptables": false,
+  "bridge": "none"
+}
+EOF
+
+sudo systemctl start docker
+```
+
+#### Alternative Approach 2: Podman as Docker Alternative
+```bash
+# Install podman as Docker drop-in replacement
+sudo dnf install -y podman podman-docker
+
+# Test with Tdarr container
+podman run --rm ghcr.io/haveagitgat/tdarr_node:latest --help
+```
+
+#### Alternative Approach 3: Docker Desktop
+```bash
+# Consider Docker Desktop for Linux (handles networking differently)
+# May bypass system iptables issues entirely
+```
+
+#### Alternative Approach 4: Deep System Cleanup
+```bash
+# Nuclear option: Remove all networking packages and reinstall
+sudo dnf remove -y iptables* nftables firewalld
+sudo dnf install -y iptables-legacy iptables-nft firewalld
+sudo dnf reinstall -y docker-ce
+```
+
+### Diagnostic Commands for Next Session
+```bash
+# Full network state capture
+ip addr show
+ip route show
+sudo iptables-save > /tmp/iptables-state.txt
+sudo nft list ruleset > /tmp/nft-state.txt
+
+# Docker troubleshooting
+sudo dockerd --debug --log-level=debug > /tmp/docker-debug.log 2>&1 &
+# Kill after 30 seconds and examine log
+
+# System journal deep dive
+journalctl -u docker.service --since="1 hour ago" -o verbose > /tmp/docker-journal.log
+```
+
+## Known Working Configuration Target
+
+### Expected Working State
+- **iptables**: Legacy backend active
+- **Docker**: Running with NAT chain creation successful
+- **Network**: Docker bridge network functional
+- **Containers**: Can start and access network
+
+### Tdarr Node Test Command
+```bash
+cd ~/docker/tdarr-node
+# Update IP in compose file first:
+# serverIP=<TDARR_SERVER_IP>
+docker-compose -f tdarr-node-basic.yml up -d
+```
+
+## Related Documentation Created
+- `/patterns/docker/gpu-acceleration.md` - GPU troubleshooting patterns
+- `/reference/docker/nvidia-troubleshooting.md` - NVIDIA container toolkit
+- `/examples/docker/tdarr-node-local/` - Working configurations
+
+## System Context Notes
+- This is a gaming-focused Nobara distribution
+- May have different default networking than standard Fedora
+- NVIDIA drivers already working (nvidia-smi functional)
+- System has been used for other Docker containers successfully in past
+- Recent NVIDIA container toolkit installation may have triggered the issue
+
+## Success Criteria for Next Session
+1. ✅ Docker service starts without errors
+2. ✅ `docker ps` command works
+3. ✅ Simple container can run: `docker run --rm hello-world`
+4. ✅ Tdarr node container can start (even if can't connect to server yet)
+5. ✅ Network connectivity from containers works
+
+## Escalation Options
+If standard troubleshooting fails:
+1. **Nobara Community**: Check Nobara Discord/forums for similar issues
+2. **Docker Desktop**: Use different Docker implementation
+3. **Podman Migration**: Switch to podman as Docker replacement
+4. **System Reinstall**: Fresh OS install (nuclear option)
+5. **Container Alternatives**: LXC/systemd containers instead of Docker
+
+## Files to Check Next Session

+# Docker Container Troubleshooting Guide
+
+## Container Startup Issues
+
+### Container Won't Start
+**Check container logs first**:
+```bash
+# Docker
+docker logs <container_name>
+docker logs --tail 50 -f <container_name>
+
+# Podman  
+podman logs <container_name>
+podman logs --tail 50 -f <container_name>
+```
+
+### Common Startup Failures
+
+#### Port Conflicts
+**Symptoms**: `bind: address already in use` error
+**Solution**:
+```bash
+# Find conflicting process
+sudo netstat -tulpn | grep <port>
+docker ps | grep <port>
+
+# Change port mapping
+docker run -p 8081:8080 myapp  # Use different host port
+```
+
+#### Permission Errors
+**Symptoms**: `permission denied` when accessing files/volumes
+**Solutions**:
+```bash
+# Check file ownership
+ls -la /host/volume/path
+
+# Fix ownership (match container user)
+sudo chown -R 1000:1000 /host/volume/path
+
+# Use correct UID/GID in container
+docker run -e PUID=1000 -e PGID=1000 myapp
+```
+
+#### Missing Environment Variables
+**Symptoms**: Application fails with configuration errors
+**Diagnostic**:
+```bash
+# Check container environment
+docker exec -it <container> env
+docker exec -it <container> printenv
+
+# Verify required variables are set
+docker inspect <container> | grep -A 20 "Env"
+```
+
+#### Resource Constraints
+**Symptoms**: Container killed or OOM errors
+**Solutions**:
+```bash
+# Check resource usage
+docker stats <container>
+
+# Increase memory limit
+docker run -m 4g myapp
+
+# Check system resources
+free -h
+df -h
+```
+
+### Debug Running Containers
+```bash
+# Access container shell
+docker exec -it <container> /bin/bash
+docker exec -it <container> /bin/sh  # if bash not available
+
+# Check container processes
+docker exec <container> ps aux
+
+# Check container filesystem
+docker exec <container> ls -la /app
+```
+
+## Build Issues
+
+### Build Failures
+**Clear build cache when encountering issues**:
+```bash
+# Docker
+docker system prune -a
+docker builder prune
+
+# Podman
+podman system prune -a
+podman image prune -a
+```
+
+### Verbose Build Output
+```bash
+# Docker
+docker build --progress=plain --no-cache .
+
+# Podman  
+podman build --layers=false .
+```
+
+### Common Build Problems
+
+#### COPY/ADD Errors
+**Issue**: Files not found during build
+**Solutions**:
+```dockerfile
+# Check .dockerignore file
+# Verify file paths relative to build context
+COPY ./src /app/src  # ✅ Correct
+COPY /absolute/path /app  # ❌ Wrong - no absolute paths
+```
+
+#### Package Installation Failures
+**Issue**: apt/yum/dnf package installation fails
+**Solutions**:
+```dockerfile
+# Update package lists first
+RUN apt-get update && apt-get install -y package-name
+
+# Combine RUN commands to reduce layers
+RUN apt-get update && \
+    apt-get install -y package1 package2 && \
+    apt-get clean && \
+    rm -rf /var/lib/apt/lists/*
+```
+
+#### Network Issues During Build
+**Issue**: Cannot reach package repositories
+**Solutions**:
+```bash
+# Check DNS resolution
+docker build --network host .
+
+# Use custom DNS
+docker build --dns 8.8.8.8 .
+```
+
+## GPU Container Issues
+
+### NVIDIA GPU Support Problems
+
+#### Docker Desktop vs Podman on Fedora/Nobara
+**Issue**: Docker Desktop has GPU compatibility issues on Fedora-based systems
+**Symptoms**:
+- `CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected`
+- `unknown or invalid runtime name: nvidia`
+- Device nodes exist but CUDA fails to initialize
+
+**Solution**: Use Podman instead of Docker on Fedora systems
+```bash
+# Verify host GPU works
+nvidia-smi
+
+# Test with Podman (recommended)
+podman run --rm --device nvidia.com/gpu=all ubuntu:20.04 nvidia-smi
+
+# Test with Docker (may fail on Fedora)
+docker run --rm --gpus all ubuntu:20.04 nvidia-smi
+```
+
+#### GPU Container Configuration
+**Working Podman GPU template**:
+```bash
+podman run -d --name gpu-container \
+    --device nvidia.com/gpu=all \
+    --restart unless-stopped \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    -e NVIDIA_VISIBLE_DEVICES=all \
+    myapp:latest
+```
+
+**Working Docker GPU template**:
+```bash
+docker run -d --name gpu-container \
+    --gpus all \
+    --restart unless-stopped \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    -e NVIDIA_VISIBLE_DEVICES=all \
+    myapp:latest
+```
+
+#### GPU Troubleshooting Steps
+1. **Verify Host GPU Access**:
+   ```bash
+   nvidia-smi                    # Should show GPU info
+   lsmod | grep nvidia          # Should show nvidia modules
+   ls -la /dev/nvidia*          # Should show device files
+   ```
+
+2. **Check NVIDIA Container Toolkit**:
+   ```bash
+   rpm -qa | grep nvidia-container-toolkit  # Fedora/RHEL
+   dpkg -l | grep nvidia-container-toolkit  # Ubuntu/Debian
+   nvidia-ctk --version
+   ```
+
+3. **Test GPU in Container**:
+   ```bash
+   # Should show GPU information
+   podman exec gpu-container nvidia-smi
+   
+   # Test CUDA functionality
+   podman exec gpu-container nvidia-ml-py
+   ```
+
+#### Platform-Specific GPU Notes
+**Fedora/Nobara/RHEL**:
+- ✅ Podman: Works out-of-the-box with GPU support
+- ❌ Docker Desktop: Known GPU integration issues
+- Solution: Use Podman for GPU workloads
+
+**Ubuntu/Debian**:
+- ✅ Docker: Generally works well with proper NVIDIA toolkit setup
+- ✅ Podman: Also works well
+- Solution: Either runtime typically works
+
+## Performance Issues
+
+### Resource Monitoring
+**Real-time resource usage**:
+```bash
+# Overall container stats
+docker stats
+podman stats
+
+# Inside container analysis
+docker exec <container> top
+docker exec <container> free -h
+docker exec <container> df -h
+
+# Network usage
+docker exec <container> netstat -i
+```
+
+### Image Size Optimization
+**Analyze image layers**:
+```bash
+# Check image sizes
+docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}"
+
+# Analyze layer history
+docker history <image>
+
+# Find large files in container
+docker exec <container> du -sh /* | sort -hr
+```
+
+**Optimization strategies**:
+```dockerfile
+# Use multi-stage builds
+FROM node:18 AS builder
+# ... build steps ...
+
+FROM node:18-alpine AS production
+COPY --from=builder /app/dist /app
+# Smaller final image
+
+# Combine RUN commands
+RUN apt-get update && \
+    apt-get install -y package && \
+    apt-get clean && \
+    rm -rf /var/lib/apt/lists/*
+
+# Use .dockerignore
+# .dockerignore
+node_modules
+.git
+*.log
+```
+
+### Storage Performance Issues
+**Slow volume performance**:
+```bash
+# Test volume I/O performance
+docker exec <container> dd if=/dev/zero of=/volume/test bs=1M count=1000
+
+# Check volume mount options
+docker inspect <container> | grep -A 10 "Mounts"
+
+# Consider using tmpfs for temporary data
+docker run --tmpfs /tmp myapp
+```
+
+## Network Debugging
+
+### Network Connectivity Issues
+**Inspect network configuration**:
+```bash
+# List networks
+docker network ls
+podman network ls
+
+# Inspect specific network
+docker network inspect <network_name>
+
+# Check container networking
+docker exec <container> ip addr show
+docker exec <container> ip route show
+```
+
+### Service Discovery Problems
+**Test connectivity between containers**:
+```bash
+# Test by container name (same network)
+docker exec container1 ping container2
+
+# Test by IP address
+docker exec container1 ping 172.17.0.3
+
+# Check DNS resolution
+docker exec container1 nslookup container2
+```
+
+### Port Binding Issues
+**Verify port mappings**:
+```bash
+# Check exposed ports
+docker port <container>
+
+# Test external connectivity
+curl localhost:8080
+
+# Check if port is bound to all interfaces
+netstat -tulpn | grep :8080
+```
+
+## Emergency Recovery
+
+### Complete Container Reset
+**Remove all containers and start fresh**:
+```bash
+# Stop all containers
+docker stop $(docker ps -q)
+podman stop --all
+
+# Remove all containers
+docker container prune -f
+podman container prune -f
+
+# Remove all images
+docker image prune -a -f
+podman image prune -a -f
+
+# Remove all volumes (CAUTION: data loss)
+docker volume prune -f
+podman volume prune -f
+
+# Complete system cleanup
+docker system prune -a --volumes -f
+podman system prune -a --volumes -f
+```
+
+### Container Recovery
+**Recover from corrupted container**:
+```bash
+# Create backup of container data
+docker cp <container>:/important/data ./backup/
+
+# Export container filesystem
+docker export <container> > container-backup.tar
+
+# Import and restart
+docker import container-backup.tar new-image:latest
+docker run -d --name new-container new-image:latest
+```
+
+### Data Recovery
+**Recover data from volumes**:
+```bash
+# List volumes
+docker volume ls
+
+# Inspect volume location
+docker volume inspect <volume_name>
+
+# Access volume data directly
+sudo ls -la /var/lib/docker/volumes/<volume_name>/_data
+
+# Mount volume to temporary container
+docker run --rm -v <volume_name>:/data alpine ls -la /data
+```
+
+## Health Check Issues
+
+### Container Health Checks
+**Implement health checks**:
+```dockerfile
+# Dockerfile health check
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+    CMD curl -f http://localhost:3000/health || exit 1
+```
+
+**Debug health check failures**:
+```bash
+# Check health status
+docker inspect <container> | grep -A 10 Health
+
+# Manual health check test
+docker exec <container> curl -f http://localhost:3000/health
+
+# Check health check logs
+docker events --filter container=<container>
+```
+
+## Log Analysis
+
+### Log Management
+**View and manage container logs**:
+```bash
+# View recent logs
+docker logs --tail 100 <container>
+
+# Follow logs in real-time
+docker logs -f <container>
+
+# Logs with timestamps
+docker logs -t <container>
+
+# Search logs for errors
+docker logs <container> 2>&1 | grep ERROR
+```
+
+### Log Rotation Issues
+**Configure log rotation to prevent disk filling**:
+```bash
+# Run with log size limits
+docker run --log-opt max-size=10m --log-opt max-file=3 myapp
+
+# Check log file sizes
+sudo du -sh /var/lib/docker/containers/*/
+```
+
+## Platform-Specific Issues
+
+### Fedora/Nobara/RHEL Systems
+- **GPU Support**: Use Podman instead of Docker Desktop
+- **SELinux**: May require container contexts (`-Z` flag)
+- **Firewall**: Configure firewalld for container networking
+
+### Ubuntu/Debian Systems  
+- **AppArmor**: May restrict container operations
+- **Snap Docker**: May have permission issues vs native package
+
+### General Linux Issues
+- **cgroups v2**: Some older containers need cgroups v1
+- **User namespaces**: May cause UID/GID mapping issues
+- **systemd**: Integration differences between Docker/Podman
+
+## Prevention Best Practices
+
+1. **Resource Limits**: Always set memory and CPU limits
+2. **Health Checks**: Implement application health monitoring
+3. **Log Rotation**: Configure to prevent disk space issues
+4. **Security Scanning**: Regular vulnerability scans
+5. **Backup Strategy**: Regular data and configuration backups
+6. **Testing**: Test containers in staging before production
+7. **Documentation**: Document container configurations and dependencies
+
+This troubleshooting guide covers the most common Docker and Podman container issues encountered in home lab and production environments.

+# System Monitoring and Alerting - Technology Context
+
+## Overview
+Comprehensive monitoring and alerting system for home lab infrastructure with focus on automated health checks, Discord notifications, and proactive system maintenance.
+
+## Architecture Patterns
+
+### Distributed Monitoring Strategy
+**Pattern**: Service-specific monitoring with centralized alerting
+- **Tdarr Monitoring**: API-based transcoding health checks
+- **Windows Desktop Monitoring**: Reboot detection and system events
+- **Network Monitoring**: Connectivity and service availability
+- **Container Monitoring**: Docker/Podman health and resource usage
+
+### Alert Management
+**Pattern**: Structured notifications with actionable information
+```bash
+# Discord webhook integration
+curl -X POST "$DISCORD_WEBHOOK" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "content": "**System Alert**\n```\nService: Tdarr\nIssue: Staging timeout\nAction: Automatic cleanup performed\n```\n<@user_id>"
+  }'
+```
+
+## Core Monitoring Components
+
+### Tdarr System Monitoring
+**Purpose**: Monitor transcoding pipeline health and performance
+**Location**: `scripts/tdarr_monitor.py`
+
+**Key Features**:
+- API-based status monitoring with dataclass structures
+- Staging section timeout detection and cleanup
+- Discord notifications with professional formatting
+- Log rotation and retention management
+
+### Windows Desktop Monitoring
+**Purpose**: Track Windows system reboots and power events
+**Location**: `scripts/windows-desktop/`
+
+**Components**:
+- PowerShell monitoring script
+- Scheduled task automation
+- Discord notification integration
+- System event correlation
+
+### Network and Service Monitoring
+**Purpose**: Monitor critical infrastructure availability
+**Implementation**:
+```bash
+# Service health check pattern
+SERVICES="https://homelab.local http://nas.homelab.local"
+for service in $SERVICES; do
+    if curl -sSf --max-time 10 "$service" >/dev/null 2>&1; then
+        echo "✅ $service: Available"
+    else
+        echo "❌ $service: Failed" | send_alert
+    fi
+done
+```
+
+## Automation Patterns
+
+### Cron-Based Scheduling
+**Pattern**: Regular health checks with intelligent alerting
+```bash
+# Monitoring schedule examples
+*/20 * * * * /path/to/tdarr-timeout-monitor.sh    # Every 20 minutes
+0 */6 * * * /path/to/cleanup-temp-dirs.sh         # Every 6 hours
+0 2 * * * /path/to/backup-monitor.sh              # Daily at 2 AM
+```
+
+### Event-Driven Monitoring
+**Pattern**: Reactive monitoring for critical events
+- **System Startup**: Windows boot detection
+- **Service Failures**: Container restart alerts  
+- **Resource Exhaustion**: Disk space warnings
+- **Security Events**: Failed login attempts
+
+## Data Collection and Analysis
+
+### Log Management
+**Pattern**: Centralized logging with rotation
+```bash
+# Log rotation configuration
+LOG_FILE="/var/log/homelab-monitor.log"
+MAX_SIZE="10M"
+RETENTION_DAYS=30
+
+# Rotate logs when size exceeded
+if [ $(stat -c%s "$LOG_FILE") -gt $((10*1024*1024)) ]; then
+    mv "$LOG_FILE" "$LOG_FILE.$(date +%Y%m%d)"
+    touch "$LOG_FILE"
+fi
+```
+
+### Metrics Collection
+**Pattern**: Time-series data for trend analysis
+- **System Metrics**: CPU, memory, disk usage
+- **Service Metrics**: Response times, error rates
+- **Application Metrics**: Transcoding progress, queue sizes
+- **Network Metrics**: Bandwidth usage, latency
+
+## Alert Integration
+
+### Discord Notification System
+**Pattern**: Rich, actionable notifications
+```markdown
+# Professional alert format
+**🔧 System Maintenance**
+Service: Tdarr Transcoding
+Issue: 3 files timed out in staging
+Resolution: Automatic cleanup completed
+Status: System operational
+
+Manual review recommended <@user_id>
+```
+
+### Alert Escalation
+**Pattern**: Tiered alerting based on severity
+1. **Info**: Routine maintenance completed
+2. **Warning**: Service degradation detected
+3. **Critical**: Service failure requiring immediate attention
+4. **Emergency**: System-wide failure requiring manual intervention
+
+## Best Practices Implementation
+
+### Monitoring Strategy
+1. **Proactive**: Monitor trends to predict issues
+2. **Reactive**: Alert on current failures
+3. **Preventive**: Automated cleanup and maintenance
+4. **Comprehensive**: Cover all critical services
+5. **Actionable**: Provide clear resolution paths
+
+### Performance Optimization
+1. **Efficient Polling**: Balance monitoring frequency with resource usage
+2. **Smart Alerting**: Avoid alert fatigue with intelligent filtering
+3. **Resource Management**: Monitor the monitoring system itself
+4. **Scalable Architecture**: Design for growth and additional services
+
+This technology context provides the foundation for implementing comprehensive monitoring and alerting in home lab environments.

+# Cron Job Management Patterns
+
+This document outlines the cron job patterns and management strategies used in the home lab environment.
+
+## Current Cron Schedule
+
+### Overview
+```bash
+# Monthly maintenance
+0 2 1 * * /home/cal/bin/ssh_key_maintenance.sh
+
+# Tdarr monitoring and management
+*/10 * * * * python3 /mnt/NV2/Development/claude-home/scripts/tdarr_monitor.py --server http://10.10.0.43:8265 --check nodes --detect-stuck --discord-alerts >/dev/null 2>&1
+0 */6 * * * find "/mnt/NV2/tdarr-cache/nobara-pc-gpu-unmapped/temp/" -name "tdarr-workDir2-*" -type d -mmin +360 -exec rm -rf {} \; 2>/dev/null || true
+0 3 * * * find "/mnt/NV2/tdarr-cache/nobara-pc-gpu-unmapped/media" -name "*.temp" -o -name "*.tdarr" -mtime +1 -delete 2>/dev/null || true
+
+# Disabled/legacy jobs
+#*/20 * * * * /mnt/NV2/Development/claude-home/scripts/monitoring/tdarr-timeout-monitor.sh
+```
+
+## Job Categories
+
+### 1. System Maintenance
+**SSH Key Maintenance**
+- **Schedule**: `0 2 1 * *` (Monthly, 1st at 2 AM)
+- **Purpose**: Maintain SSH key security and rotation
+- **Location**: `/home/cal/bin/ssh_key_maintenance.sh`
+- **Priority**: High (security-critical)
+
+### 2. Monitoring & Alerting
+**Tdarr System Monitoring**
+- **Schedule**: `*/10 * * * *` (Every 10 minutes)
+- **Purpose**: Monitor Tdarr nodes, detect stuck jobs, send Discord alerts
+- **Features**:
+  - Stuck job detection (30-minute threshold)
+  - Discord notifications with rich embeds
+  - Persistent memory state tracking
+- **Script**: `/mnt/NV2/Development/claude-home/scripts/tdarr_monitor.py`
+- **Output**: Silent (`>/dev/null 2>&1`)
+
+### 3. Cleanup & Housekeeping
+**Tdarr Work Directory Cleanup**
+- **Schedule**: `0 */6 * * *` (Every 6 hours)
+- **Purpose**: Remove stale Tdarr work directories
+- **Target**: `/mnt/NV2/tdarr-cache/nobara-pc-gpu-unmapped/temp/`
+- **Pattern**: `tdarr-workDir2-*` directories
+- **Age threshold**: 6 hours (`-mmin +360`)
+
+**Failed Tdarr Job Cleanup**
+- **Schedule**: `0 3 * * *` (Daily at 3 AM)
+- **Purpose**: Remove failed transcode artifacts
+- **Target**: `/mnt/NV2/tdarr-cache/nobara-pc-gpu-unmapped/media/`
+- **Patterns**: `*.temp` and `*.tdarr` files
+- **Age threshold**: 24 hours (`-mtime +1`)
+
+## Design Patterns
+
+### 1. Absolute Paths
+**Always use absolute paths in cron jobs**
+```bash
+# Good
+*/10 * * * * python3 /full/path/to/script.py
+
+# Bad - relative paths don't work in cron
+*/10 * * * * python3 scripts/script.py
+```
+
+### 2. Error Handling
+**Standard error suppression pattern**
+```bash
+command 2>/dev/null || true
+```
+- Suppresses stderr to prevent cron emails
+- `|| true` ensures job always exits successfully
+
+### 3. Time-based Cleanup
+**Safe age thresholds for different content types**
+- **Work directories**: 6 hours (short-lived, safe for active jobs)
+- **Temp files**: 24 hours (allows for long transcodes)
+- **Log files**: 7-30 days (depending on importance)
+
+### 4. Resource-aware Scheduling
+**Avoid resource conflicts**
+```bash
+# System maintenance at low-usage times
+0 2 1 * * maintenance_script.sh
+
+# Cleanup during off-peak hours  
+0 3 * * * cleanup_script.sh
+
+# Monitoring with high frequency during active hours
+*/10 * * * * monitor_script.py
+```
+
+## Management Workflow
+
+### Adding New Cron Jobs
+
+1. **Backup current crontab**
+   ```bash
+   crontab -l > /tmp/crontab_backup_$(date +%Y%m%d)
+   ```
+
+2. **Edit safely**
+   ```bash
+   crontab -l > /tmp/new_crontab
+   echo "# New job description" >> /tmp/new_crontab
+   echo "schedule command" >> /tmp/new_crontab
+   crontab /tmp/new_crontab
+   ```
+
+3. **Verify installation**
+   ```bash
+   crontab -l
+   ```
+
+### Proper HERE Document (EOF) Usage
+
+**When building cron files with HERE documents, use proper EOF formatting:**
+
+#### ✅ **Correct Format**
+```bash
+cat > /tmp/new_crontab << 'EOF'
+0 2 1 * * /home/cal/bin/ssh_key_maintenance.sh
+# Tdarr monitoring every 10 minutes
+*/10 * * * * python3 /path/to/script.py --args
+EOF
+```
+
+#### ❌ **Common Mistakes**
+```bash
+# BAD - Causes "EOF not found" errors
+cat >> /tmp/crontab << 'EOF'
+new_cron_job
+EOF
+
+# Results in malformed file with literal "EOF < /dev/null" lines
+```
+
+#### **Key Rules for EOF in Cron Files**
+
+1. **Use `cat >` not `cat >>`** for building complete files
+   ```bash
+   # Good - overwrites file cleanly
+   cat > /tmp/crontab << 'EOF'
+   
+   # Bad - appends and can create malformed files
+   cat >> /tmp/crontab << 'EOF'
+   ```
+
+2. **Quote the EOF delimiter** to prevent variable expansion
+   ```bash
+   # Good - literal content
+   cat > file << 'EOF'
+   
+   # Can cause issues with special characters
+   cat > file << EOF
+   ```
+
+3. **Clean up malformed files** before installing
+   ```bash
+   # Remove EOF artifacts and empty lines
+   head -n -1 /tmp/crontab > /tmp/clean_crontab
+   
+   # Or use grep to remove EOF lines
+   grep -v "^EOF" /tmp/crontab > /tmp/clean_crontab
+   ```
+
+4. **Alternative approach - direct echo method**
+   ```bash
+   crontab -l > /tmp/current_crontab
+   echo "# New job comment" >> /tmp/current_crontab
+   echo "*/10 * * * * /path/to/command" >> /tmp/current_crontab
+   crontab /tmp/current_crontab
+   ```
+
+#### **Debugging EOF Issues**
+
+```bash
+# Check for EOF artifacts in crontab file
+cat -n /tmp/crontab | grep EOF
+
+# Validate crontab syntax before installing
+crontab -T /tmp/crontab  # Some systems support this
+
+# Manual cleanup if needed
+sed '/^EOF/d' /tmp/crontab > /tmp/clean_crontab
+```
+
+### Testing Cron Jobs
+
+**Test command syntax first**
+```bash
+# Test the actual command before scheduling
+python3 /full/path/to/script.py --test
+
+# Check file permissions
+ls -la /path/to/script
+
+# Verify paths exist
+ls -la /target/directory/
+```
+
+**Test with minimal frequency**
+```bash
+# Start with 5-minute intervals for testing
+*/5 * * * * /path/to/new/script.sh
+
+# Monitor logs
+tail -f /var/log/syslog | grep CRON
+```
+
+### Monitoring Cron Jobs
+
+**Check cron logs**
+```bash
+# System cron logs
+sudo journalctl -u cron -f
+
+# User cron logs  
+grep CRON /var/log/syslog | grep $(whoami)
+```
+
+**Verify job execution**
+```bash
+# Check if cleanup actually ran
+ls -la /target/cleanup/directory/
+
+# Monitor script logs
+tail -f /path/to/script/logs/
+```
+
+## Security Considerations
+
+### 1. Path Security
+- Use absolute paths to prevent PATH manipulation
+- Ensure scripts are owned by correct user
+- Set appropriate permissions (750 for scripts)
+
+### 2. Command Injection Prevention
+```bash
+# Good - quoted paths
+find "/path/with spaces/" -name "pattern"
+
+# Bad - unquoted paths vulnerable to injection
+find /path/with spaces/ -name pattern
+```
+
+### 3. Resource Limits
+- Prevent runaway processes with `timeout`
+- Use `ionice` for I/O intensive cleanup jobs
+- Consider `nice` for CPU-intensive tasks
+
+## Troubleshooting
+
+### Common Issues
+
+**Job not running**
+1. Check cron service: `sudo systemctl status cron`
+2. Verify crontab syntax: `crontab -l`
+3. Check file permissions and paths
+4. Review cron logs for errors
+
+**Environment differences**
+- Cron runs with minimal environment
+- Set PATH explicitly if needed
+- Use absolute paths for all commands
+
+**Silent failures**
+- Remove `2>/dev/null` temporarily for debugging
+- Add logging to scripts
+- Check script exit codes
+
+### Debugging Commands
+```bash
+# Test cron environment
+* * * * * env > /tmp/cron_env.txt
+
+# Test script in cron-like environment
+env -i /bin/bash -c 'your_command_here'
+
+# Monitor real-time execution
+sudo tail -f /var/log/syslog | grep CRON
+```
+
+## Best Practices
+
+### 1. Documentation
+- Comment all cron jobs with purpose and schedule
+- Document in this patterns file
+- Include contact info for complex jobs
+
+### 2. Maintenance
+- Regular review of active jobs (quarterly)
+- Remove obsolete jobs promptly
+- Update absolute paths when moving scripts
+
+### 3. Monitoring
+- Implement health checks for critical jobs
+- Use Discord/email notifications for failures
+- Monitor disk space usage from cleanup jobs
+
+### 4. Backup Strategy
+- Backup crontab before changes
+- Version control cron configurations
+- Document restoration procedures
+
+## Future Enhancements
+
+### Planned Additions
+- **Log rotation**: Automated cleanup of application logs
+- **Health checks**: System resource monitoring
+- **Backup verification**: Automated backup integrity checks
+- **Certificate renewal**: SSL/TLS certificate automation
+
+### Migration Considerations
+- **Systemd timers**: Consider migration for complex scheduling
+- **Configuration management**: Ansible or similar for multi-host
+- **Centralized logging**: Aggregated cron job monitoring

+# Allow PowerShell through firewall
+New-NetFirewallRule -DisplayName "PowerShell Outbound" -Direction Outbound -Program "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -Action Allow
+
+# Test with simplified request
+$body = @{content="Test from Windows"} | ConvertTo-Json
+Invoke-RestMethod -Uri $webhookUrl -Method Post -Body $body -ContentType "application/json"
+```
+
+## Log Management Issues
+
+### Log Files Growing Too Large
+**Symptoms**: Disk space filling up, slow log access
+**Diagnosis**:
+```bash
+# Check log file sizes
+du -sh /var/log/homelab-*
+du -sh /tmp/*monitor*.log
+
+# Check available disk space
+df -h /var/log
+df -h /tmp
+```
+
+**Solutions**:
+```bash
+# Implement log rotation
+cat > /etc/logrotate.d/homelab-monitoring << 'EOF'
+/var/log/homelab-*.log {
+    daily
+    missingok
+    rotate 7
+    compress
+    notifempty
+    create 644 root root
+}
+EOF
+
+# Manual log cleanup
+find /tmp -name "*monitor*.log" -size +10M -delete
+truncate -s 0 /tmp/large-log-file.log
+```
+
+### Log Rotation Not Working
+**Symptoms**: Old logs not being cleaned up
+**Diagnosis**:
+```bash
+# Check logrotate status
+systemctl status logrotate
+cat /var/lib/logrotate/status
+
+# Test logrotate configuration
+logrotate -d /etc/logrotate.d/homelab-monitoring
+```
+
+**Solutions**:
+```bash
+# Force log rotation
+logrotate -f /etc/logrotate.d/homelab-monitoring
+
+# Fix logrotate configuration
+sudo nano /etc/logrotate.d/homelab-monitoring
+# Verify syntax and permissions
+```
+
+## Cron Job Issues
+
+### Scheduled Tasks Not Running
+**Symptoms**: Scripts not executing at scheduled times
+**Diagnosis**:
+```bash
+# Check cron service
+systemctl status cron
+systemctl status crond  # RHEL/CentOS
+
+# View cron logs
+grep CRON /var/log/syslog
+journalctl -u cron
+
+# List all cron jobs
+crontab -l
+sudo crontab -l  # System crontab
+```
+
+**Solutions**:
+```bash
+# Restart cron service
+sudo systemctl restart cron
+
+# Fix cron job syntax
+# Ensure absolute paths are used
+# Example: */20 * * * * /full/path/to/script.sh
+
+# Check script permissions and execution
+ls -la /path/to/script.sh
+/path/to/script.sh  # Test manual execution
+```
+
+### Environment Variables in Cron
+**Symptoms**: Scripts work manually but fail in cron
+**Diagnosis**:
+```bash
+# Create test cron job to check environment
+* * * * * env > /tmp/cron-env.txt
+
+# Compare with shell environment
+env > /tmp/shell-env.txt
+diff /tmp/shell-env.txt /tmp/cron-env.txt
+```
+
+**Solutions**:
+```bash
+# Set PATH in crontab
+PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+
+# Or set PATH in script
+#!/bin/bash
+export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
+
+# Source environment if needed
+source /etc/environment
+```
+
+## Network Monitoring Issues
+
+### False Positives
+**Symptoms**: Alerts for services that are actually working
+**Diagnosis**:
+```bash
+# Test monitoring checks manually
+curl -sSf --max-time 10 "https://service.homelab.local"
+ping -c1 -W5 10.10.0.100
+
+# Check for intermittent network issues
+for i in {1..10}; do ping -c1 host || echo "Fail $i"; done
+```
+
+**Solutions**:
+```bash
+# Adjust timeout values
+curl --max-time 30 "$service"  # Increase timeout
+
+# Add retry logic
+for retry in {1..3}; do
+    if curl -sSf "$service" >/dev/null 2>&1; then
+        break
+    elif [ $retry -eq 3 ]; then
+        send_alert "Service $service failed after 3 retries"
+    fi
+    sleep 5
+done
+```
+
+### Missing Alerts
+**Symptoms**: Real failures not triggering notifications
+**Diagnosis**:
+```bash
+# Verify monitoring script logic
+bash -x monitoring-script.sh
+
+# Check if services are actually down
+systemctl status service-name
+curl -v service-url
+```
+
+**Solutions**:
+```bash
+# Lower detection thresholds
+# Increase monitoring frequency
+# Add redundant monitoring methods
+
+# Test alert mechanism
+echo "Test alert" | send_alert_function
+```
+
+## System Resource Issues
+
+### Monitoring Overhead
+**Symptoms**: High CPU/memory usage from monitoring scripts
+**Diagnosis**:
+```bash
+# Monitor the monitoring scripts
+top -p $(pgrep -f monitor)
+ps aux | grep monitor
+
+# Check monitoring frequency
+crontab -l | grep monitor
+```
+
+**Solutions**:
+```bash
+# Reduce monitoring frequency
+# Change from */1 to */5 minutes
+
+# Optimize scripts
+# Remove unnecessary commands
+# Use efficient tools (prefer curl over wget, etc.)
+
+# Add resource limits
+timeout 30 monitoring-script.sh
+```
+
+## Emergency Recovery
+
+### Complete Monitoring Failure
+**Recovery Steps**:
+```bash
+# Restart all monitoring services
+sudo systemctl restart cron
+sudo systemctl restart rsyslog
+
+# Reinstall monitoring scripts
+cd /path/to/scripts
+./install-monitoring.sh
+
+# Test all components
+./test-monitoring.sh
+```
+
+### Discord Integration Lost
+**Quick Recovery**:
+```bash
+# Test webhook
+curl -X POST "$BACKUP_WEBHOOK_URL" -H "Content-Type: application/json" -d '{"content": "Monitoring restored"}'
+
+# Switch to backup webhook if needed
+export DISCORD_WEBHOOK_URL="$BACKUP_WEBHOOK_URL"
+```
+
+## Prevention and Best Practices
+
+### Monitoring Health Checks
+```bash
+#!/bin/bash
+# monitor-the-monitors.sh
+MONITORING_SCRIPTS="/path/to/tdarr-monitor.sh /path/to/network-monitor.sh"
+
+for script in $MONITORING_SCRIPTS; do
+    if [ ! -x "$script" ]; then
+        echo "ALERT: $script not executable" | send_alert
+    fi
+    
+    # Check if script has run recently
+    if [ $(($(date +%s) - $(stat -c %Y "$script.last_run" 2>/dev/null || echo 0))) -gt 3600 ]; then
+        echo "ALERT: $script hasn't run in over an hour" | send_alert
+    fi
+done
+```
+
+### Backup Alerting Channels
+```bash
+# Multiple notification methods
+send_alert() {
+    local message="$1"
+    
+    # Primary: Discord
+    curl -X POST "$DISCORD_WEBHOOK" -d "{\"content\":\"$message\"}" || \
+    # Backup: Email
+    echo "$message" | mail -s "Homelab Alert" admin@domain.com || \
+    # Last resort: Local log
+    echo "$(date): $message" >> /var/log/critical-alerts.log
+}
+```

+# Networking Infrastructure - Technology Context
+
+## Overview
+Home lab networking infrastructure with focus on reverse proxy configuration, SSL/TLS management, SSH key management, and network security. This context covers service discovery, load balancing, and performance optimization patterns.
+
+## Architecture Patterns
+
+### Reverse Proxy and Load Balancing
+**Pattern**: Centralized traffic management with SSL termination
+```nginx
+# Nginx reverse proxy pattern
+upstream backend {
+    server 10.10.0.100:3000;
+    server 10.10.0.101:3000;
+    keepalive 32;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name myapp.homelab.local;
+    
+    ssl_certificate /etc/ssl/certs/homelab.crt;
+    ssl_certificate_key /etc/ssl/private/homelab.key;
+    
+    location / {
+        proxy_pass http://backend;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+### Network Segmentation Strategy
+**Pattern**: VLAN-based isolation with controlled inter-VLAN routing
+```
+Management VLAN: 10.10.0.x/24   # VM management, SSH access
+Services VLAN:   10.10.1.x/24   # Application services
+Storage VLAN:    10.10.2.x/24   # NAS, backup traffic
+DMZ VLAN:        10.10.10.x/24  # External-facing services
+```
+
+## SSH Key Management
+
+### Centralized Key Distribution
+**Pattern**: Automated SSH key deployment with emergency backup
+```bash
+# Primary access key
+~/.ssh/homelab_rsa         # Daily operations key
+
+# Emergency access key
+~/.ssh/emergency_homelab_rsa  # Backup recovery key
+
+# Automated deployment
+for host in $(cat hosts.txt); do
+    ssh-copy-id -i ~/.ssh/homelab_rsa.pub user@$host
+    ssh-copy-id -i ~/.ssh/emergency_homelab_rsa.pub user@$host
+done
+```
+
+### Key Lifecycle Management
+**Pattern**: Regular rotation with zero-downtime deployment
+1. **Generation**: Create new key pairs annually
+2. **Distribution**: Deploy to all managed systems
+3. **Verification**: Test connectivity with new keys
+4. **Rotation**: Remove old keys after verification
+5. **Backup**: Store keys in secure, recoverable location
+
+## Service Discovery and DNS
+
+### Local DNS Resolution
+**Pattern**: Internal DNS for service discovery
+```bind
+# Home lab DNS zones
+homelab.local.     IN  A   10.10.0.16   # DNS server
+proxmox.homelab.local.  IN  A   10.10.0.10   # Hypervisor
+nas.homelab.local.      IN  A   10.10.0.20   # Storage
+tdarr.homelab.local.    IN  A   10.10.0.43   # Media server
+```
+
+### Container Service Discovery
+**Pattern**: Docker network-based service resolution
+```yaml
+# Docker Compose service discovery
+version: "3.8"
+services:
+  web:
+    networks:
+      - frontend
+      - backend
+  api:
+    networks:
+      - backend
+      - database
+  db:
+    networks:
+      - database
+
+networks:
+  frontend:
+    driver: bridge
+  backend:
+    driver: bridge
+  database:
+    driver: bridge
+    internal: true  # No external access
+```
+
+## Security Patterns
+
+### SSH Security Hardening
+**Configuration**: Secure SSH server setup
+```sshd_config
+# /etc/ssh/sshd_config.d/99-homelab-security.conf
+PasswordAuthentication no
+PubkeyAuthentication yes
+PermitRootLogin no
+AllowUsers cal
+Protocol 2
+ClientAliveInterval 300
+ClientAliveCountMax 2
+MaxAuthTries 3
+X11Forwarding no
+```
+
+### Network Access Control
+**Pattern**: Firewall-based service protection
+```bash
+# ufw firewall rules
+ufw default deny incoming
+ufw default allow outgoing
+ufw allow ssh
+ufw allow from 10.10.0.0/24 to any port 22
+ufw allow from 10.10.0.0/24 to any port 80
+ufw allow from 10.10.0.0/24 to any port 443
+```
+
+### SSL/TLS Certificate Management
+**Pattern**: Automated certificate lifecycle
+```bash
+# Let's Encrypt automation
+certbot certonly --nginx \
+    --email admin@homelab.local \
+    --agree-tos \
+    --domains homelab.local,*.homelab.local
+
+# Certificate renewal automation
+0 2 * * * certbot renew --quiet && systemctl reload nginx
+```
+
+## Performance Optimization
+
+### Connection Management
+**Pattern**: Optimized connection handling
+```nginx
+# Nginx performance tuning
+worker_processes auto;
+worker_connections 1024;
+
+keepalive_timeout 65;
+keepalive_requests 1000;
+
+gzip on;
+gzip_vary on;
+gzip_types text/plain text/css application/json application/javascript;
+
+# Connection pooling
+upstream backend {
+    server 10.10.0.100:3000 max_fails=3 fail_timeout=30s;
+    keepalive 32;
+}
+```
+
+### Caching Strategies
+**Pattern**: Multi-level caching architecture
+```nginx
+# Static content caching
+location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
+    expires 1y;
+    add_header Cache-Control "public, immutable";
+}
+
+# Proxy caching
+proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=app_cache:10m;
+proxy_cache app_cache;
+proxy_cache_valid 200 302 10m;
+```
+
+## Network Storage Integration
+
+### CIFS/SMB Mount Resilience
+**Pattern**: Robust network filesystem mounting
+```fstab
+//nas.homelab.local/media /mnt/media cifs \
+    credentials=/etc/cifs/credentials,\
+    uid=1000,gid=1000,\
+    file_mode=0644,dir_mode=0755,\
+    iocharset=utf8,\
+    cache=strict,\
+    actimeo=30,\
+    _netdev,\
+    reconnect,\
+    soft,\
+    rsize=1048576,\
+    wsize=1048576 0 0
+```
+
+## Monitoring and Observability
+
+### Network Health Monitoring
+**Pattern**: Automated connectivity verification
+```bash
+#!/bin/bash
+# network-health-check.sh
+HOSTS="10.10.0.10 10.10.0.20 10.10.0.43"
+DNS_SERVERS="10.10.0.16 8.8.8.8"
+
+for host in $HOSTS; do
+    if ping -c1 -W5 $host >/dev/null 2>&1; then
+        echo "✅ $host: Reachable"
+    else
+        echo "❌ $host: Unreachable"
+    fi
+done
+
+for dns in $DNS_SERVERS; do
+    if nslookup google.com $dns >/dev/null 2>&1; then
+        echo "✅ DNS $dns: Working"
+    else
+        echo "❌ DNS $dns: Failed"
+    fi
+done
+```
+
+### Service Availability Monitoring
+**Pattern**: HTTP/HTTPS endpoint monitoring
+```bash
+# Service health check
+SERVICES="https://homelab.local http://proxmox.homelab.local:8006"
+
+for service in $SERVICES; do
+    if curl -sSf --max-time 10 "$service" >/dev/null 2>&1; then
+        echo "✅ $service: Available"
+    else
+        echo "❌ $service: Unavailable"
+    fi
+done
+```
+
+## Common Integration Patterns
+
+### Reverse Proxy with Docker
+**Pattern**: Container service exposure
+```nginx
+# Dynamic service discovery with Docker
+location /api/ {
+    proxy_pass http://api-container:3000/;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+}
+
+location /web/ {
+    proxy_pass http://web-container:8080/;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";  # WebSocket support
+}
+```
+
+### VPN Integration
+**Pattern**: Secure remote access
+```openvpn
+# OpenVPN server configuration
+port 1194
+proto udp
+dev tun
+ca ca.crt
+cert server.crt
+key server.key
+dh dh.pem
+server 10.8.0.0 255.255.255.0
+push "route 10.10.0.0 255.255.0.0"  # Home lab networks
+keepalive 10 120
+```
+
+## Best Practices
+
+### Security Implementation
+1. **SSH Keys Only**: Disable password authentication everywhere
+2. **Network Segmentation**: Use VLANs for isolation
+3. **Certificate Management**: Automate SSL/TLS certificate lifecycle
+4. **Access Control**: Implement least-privilege networking
+5. **Monitoring**: Continuous network and service monitoring
+
+### Performance Optimization
+1. **Connection Pooling**: Reuse connections for efficiency
+2. **Caching**: Implement multi-level caching strategies
+3. **Compression**: Enable gzip for reduced bandwidth
+4. **Keep-Alives**: Optimize connection persistence
+5. **CDN Strategy**: Cache static content effectively
+
+### Operational Excellence
+1. **Documentation**: Maintain network topology documentation
+2. **Automation**: Script routine network operations
+3. **Backup**: Regular configuration backups
+4. **Testing**: Regular connectivity and performance testing
+5. **Change Management**: Controlled network configuration changes
+
+This technology context provides comprehensive guidance for implementing robust networking infrastructure in home lab environments.

+# Home Lab Security Improvements
+
+## Current Security Issues
+
+### Critical Issues Found:
+- **Password Authentication**: All servers using password-based SSH authentication
+- **Credential Reuse**: Same password used across 7 home network servers  
+- **Insecure Storage**: Passwords stored in FileZilla (base64 encoded, not encrypted)
+- **Root Access**: Cloud servers using root user accounts
+
+### Risk Assessment:
+- **High**: Password-based authentication vulnerable to brute force attacks
+- **High**: Shared passwords create single point of failure
+- **Medium**: FileZilla credentials accessible to anyone with file system access
+- **Medium**: Root access increases attack surface
+
+## Implemented Solutions
+
+### 1. SSH Key-Based Authentication
+- **Generated separate key pairs** for home lab vs cloud servers
+- **4096-bit RSA keys** for strong encryption
+- **Descriptive key comments** for identification
+
+### 2. SSH Configuration Management
+- **Centralized config** in `~/.ssh/config`
+- **Host aliases** for easy server access
+- **Port forwarding** pre-configured for common services
+- **Security defaults** (ServerAliveInterval, StrictHostKeyChecking)
+
+### 3. Network Segmentation
+- **Home network** (10.10.0.0/24) uses dedicated key
+- **Cloud servers** use separate key pair
+- **Service-specific aliases** for different server roles
+
+## Additional Security Recommendations
+
+### Immediate Actions:
+1. **Deploy SSH keys** using the provided script
+2. **Test key-based authentication** on all servers
+3. **Disable password authentication** once keys work
+4. **Remove FileZilla passwords** after migration
+
+### Server Hardening:
+```bash
+# On each server, edit /etc/ssh/sshd_config:
+PasswordAuthentication no
+PubkeyAuthentication yes
+PermitRootLogin no  # (create non-root user on cloud servers first)
+Port 2222  # Change default SSH port
+AllowUsers cal  # Restrict SSH access
+```
+
+### Monitoring:
+- **SSH login monitoring** with fail2ban
+- **Key rotation schedule** (annually)
+- **Access logging** review
+
+### Future Enhancements:
+- **Certificate-based authentication** (SSH CA)
+- **Multi-factor authentication** (TOTP)
+- **VPN access** for home network
+- **Bastion host** for cloud servers
+
+## Migration Plan
+
+### Phase 1: Key Deployment ✅
+- [x] Generate SSH key pairs
+- [x] Create SSH configuration
+- [x] Document server inventory
+
+### Phase 2: Authentication Migration
+- [ ] Deploy public keys to all servers
+- [ ] Test SSH connections with keys
+- [ ] Verify all services accessible
+
+### Phase 3: Security Lockdown
+- [ ] Disable password authentication
+- [ ] Change default SSH ports
+- [ ] Configure fail2ban
+- [ ] Remove FileZilla credentials
+
+### Phase 4: Monitoring & Maintenance
+- [ ] Set up access logging
+- [ ] Schedule key rotation
+- [ ] Document incident response
+
+## Connection Examples
+
+After setup, you'll connect using simple aliases:
+```bash
+# Instead of: ssh cal@10.10.0.42
+ssh database-apis
+
+# Instead of: ssh root@172.237.147.99  
+ssh akamai
+
+# With automatic port forwarding:
+ssh pihole  # Forwards port 8080 → localhost:80
+```

-## Common Patterns
-- **Multi-service applications**: Use docker-compose for local development
-- **Production deployments**: Single-container per service with orchestration
-- **Development environments**: Volume mounts for code changes
-- **CI/CD integration**: Build, test, and push in pipeline stages
-
-## Security Considerations
-- Scan images for vulnerabilities
-- Use distroless or minimal base images
-- Implement resource limits
-- Network isolation between services
-

-# Virtual Machine Management Patterns
-
-## Automated Provisioning
-- **Cloud-init deployment** - Fully automated VM provisioning from first boot
-- **Post-install scripts** - Standardized configuration for existing VMs
-- **SSH key management** - Automated key deployment with emergency backup
-- **Security hardening** - Password auth disabled, firewall configured
-
-## VM Provisioning Strategies
-
-### Template-Based Deployment
-- **Ubuntu Server templates** optimized for home lab environments
-- **Resource allocation** sizing and planning
-- **Network configuration** and VLAN assignment (10.10.0.x networks)
-- **Storage provisioning** and disk management
-
-### Infrastructure as Code
-- **Cloud-init templates** for repeatable VM creation
-- **Bash provisioning scripts** for existing infrastructure
-- **SSH key integration** with existing homelab key management
-- **Docker environment** setup with user permissions
-
-## Lifecycle Management
-- **Automated provisioning** with infrastructure as code
-- **Configuration management** with standardized scripts
-- **Snapshot management** and rollback strategies
-- **Scaling policies** for resource optimization
-
-## Monitoring & Maintenance
-- **Resource monitoring** (CPU, memory, disk, network)
-- **Health checks** and alerting systems
-- **Patch management** and update strategies
-- **Performance tuning** and optimization
-
-## Backup & Recovery
-- **VM-level backups** vs **application-level backups**
-- **Disaster recovery** planning and testing
-- **High availability** configurations
-- **Migration strategies** between hosts
-
-## Implementation Workflows
-
-### New VM Creation (Recommended)
-1. **Create VM in Proxmox** with cloud-init support
-2. **Apply cloud-init template** (`scripts/vm-management/cloud-init-user-data.yaml`)
-3. **Start VM** - fully automated provisioning
-4. **Verify setup** via SSH key authentication
-
-### Existing VM Configuration  
-1. **Run post-install script** (`scripts/vm-management/vm-post-install.sh <ip> <user>`)
-2. **Automated provisioning** handles updates, SSH keys, Docker
-3. **Security hardening** applied automatically
-4. **Test connectivity** and verify Docker installation
-
-## Security Architecture
-- **SSH key-based authentication** only (passwords disabled)
-- **Emergency key backup** for failover access  
-- **User privilege separation** (sudo required, docker group)
-- **Automatic security updates** configured
-- **Network isolation** ready (10.10.0.x internal network)
-

+# Tdarr Transcoding System - Technology Context
+
+## Overview
+Tdarr is a distributed transcoding system that converts media files to optimized formats. This implementation uses an intelligent gaming-aware scheduler with unmapped node architecture for optimal performance and system stability.
+
+## Architecture Patterns
+
+### Distributed Unmapped Node Architecture (Recommended)
+**Pattern**: Server-Node separation with local high-speed cache
+- **Server**: Tdarr Server manages queue, web interface, and coordination
+- **Node**: Unmapped nodes with local NVMe cache for processing
+- **Benefits**: 3-5x performance improvement, network I/O reduction, linear scaling
+
+**When to Use**:
+- Multiple transcoding nodes across network
+- High-performance requirements (10GB+ files)
+- Network bandwidth limitations
+- Gaming systems requiring GPU priority management
+
+### Configuration Principles
+1. **Cache Optimization**: Use local NVMe storage for work directories
+2. **Gaming Detection**: Automatic pause during GPU-intensive activities  
+3. **Resource Isolation**: Container limits prevent kernel-level crashes
+4. **Monitoring Integration**: Automated cleanup and Discord notifications
+
+## Core Components
+
+### Gaming-Aware Scheduler
+**Purpose**: Automatically manages Tdarr node to avoid conflicts with gaming
+**Location**: `scripts/tdarr-schedule-manager.sh`
+
+**Key Features**:
+- Detects gaming processes (Steam, Lutris, Wine, etc.)
+- GPU usage monitoring (>15% threshold)
+- Configurable time windows
+- Automated temporary directory cleanup
+
+**Schedule Format**: `"HOUR_START-HOUR_END:DAYS"`
+- `"22-07:daily"` - Overnight transcoding
+- `"09-17:1-5"` - Business hours weekdays only
+- `"14-16:6,7"` - Weekend afternoon window
+
+### Monitoring System
+**Purpose**: Prevents staging section timeouts and system instability
+**Location**: `scripts/monitoring/tdarr-timeout-monitor.sh`
+
+**Capabilities**:
+- Staging timeout detection (300-second hardcoded limit)
+- Automatic work directory cleanup
+- Discord notifications with user pings
+- Log rotation and retention management
+
+### Container Architecture
+**Server Configuration**:
+```yaml
+# Hybrid storage with resource limits
+services:
+  tdarr:
+    image: ghcr.io/haveagitgat/tdarr:latest
+    ports: ["8265:8266"]
+    volumes:
+      - "./tdarr-data:/app/configs"
+      - "/mnt/media:/media"
+```
+
+**Node Configuration**:
+```bash
+# Unmapped node with local cache
+podman run -d \
+  --name tdarr-node-gpu \
+  -e nodeType=unmapped \
+  -v "/mnt/NV2/tdarr-cache:/cache" \
+  --device nvidia.com/gpu=all \
+  ghcr.io/haveagitgat/tdarr_node:latest
+```
+
+## Implementation Patterns
+
+### Performance Optimization
+1. **Local Cache Strategy**: Download → Process → Upload (vs. streaming)
+2. **Resource Limits**: Prevent memory exhaustion and kernel crashes
+3. **Network Resilience**: CIFS mount options for stability
+4. **Automated Cleanup**: Prevent accumulation of stuck directories
+
+### Error Prevention
+1. **Plugin Safety**: Null-safe forEach operations `(streams || []).forEach()`
+2. **Clean Installation**: Avoid custom plugin mounts causing version conflicts
+3. **Container Isolation**: Resource limits prevent system-level crashes
+4. **Network Stability**: Unmapped architecture reduces CIFS dependency
+
+### Gaming Integration
+1. **Process Detection**: Monitor for gaming applications and utilities
+2. **GPU Threshold**: Stop transcoding when GPU usage >15%
+3. **Time Windows**: Respect user-defined allowed transcoding hours
+4. **Manual Override**: Direct start/stop commands bypass scheduler
+
+## Common Workflows
+
+### Initial Setup
+1. Start server with "Allow unmapped Nodes" enabled
+2. Configure node as unmapped with local cache
+3. Install gaming-aware scheduler via cron
+4. Set up monitoring system for automated cleanup
+
+### Troubleshooting Patterns
+1. **forEach Errors**: Clean plugin installation, avoid custom mounts
+2. **Staging Timeouts**: Monitor system handles automatic cleanup
+3. **System Crashes**: Convert to unmapped node architecture
+4. **Network Issues**: Implement CIFS resilience options
+
+### Performance Tuning
+1. **Cache Size**: 100-500GB NVMe for concurrent jobs
+2. **Bandwidth**: Unmapped nodes reduce streaming requirements
+3. **Scaling**: Linear scaling with additional unmapped nodes
+4. **GPU Priority**: Gaming detection ensures responsive system
+
+## Best Practices
+
+### Production Deployment
+- Use unmapped node architecture for stability
+- Implement comprehensive monitoring
+- Configure gaming-aware scheduling for desktop systems
+- Set appropriate container resource limits
+
+### Development Guidelines
+- Test with internal Tdarr test files first
+- Implement null-safety checks in custom plugins
+- Use structured logging for troubleshooting
+- Separate concerns: scheduling, monitoring, processing
+
+### Security Considerations
+- Container isolation prevents system-level failures
+- Resource limits protect against memory exhaustion
+- Network mount resilience prevents kernel crashes
+- Automated cleanup prevents disk space issues
+
+## Migration Patterns
+
+### From Mapped to Unmapped Nodes
+1. Enable "Allow unmapped Nodes" in server options
+2. Update node configuration (add nodeType=unmapped)
+3. Change cache volume to local storage
+4. Remove media volume mapping
+5. Test workflow and monitor performance
+
+### Plugin System Cleanup
+1. Remove all custom plugin mounts
+2. Force server restart to regenerate plugin ZIP
+3. Restart nodes to download fresh plugins
+4. Verify forEach fixes in downloaded plugins
+
+This technology context provides the foundation for implementing, troubleshooting, and optimizing Tdarr transcoding systems in home lab environments.

+# Tdarr CIFS Troubleshooting Session - 2025-08-11
+
+## Problem Statement
+Tdarr unmapped node experiencing persistent download timeouts at 9:08 PM with large files (31GB+ remux), causing "Cancelling" messages and stuck downloads. Downloads would hang for 33+ minutes before timing out, despite container remaining running.
+
+## Initial Hypothesis: Mapped vs Unmapped Node Issue
+**Status**: ❌ **DISPROVEN**
+- Suspected unmapped node timeout configuration differences
+- Windows PC running mapped Tdarr node works fine (slow but stable)
+- Both mapped and unmapped Linux nodes exhibited identical timeout issues
+- **Conclusion**: Architecture type was not the root cause
+
+## Key Insight: Windows vs Linux Performance Difference
+**Observation**: Windows Tdarr node (mapped mode) works without timeouts, Linux nodes (both mapped/unmapped) fail
+**Implication**: Platform-specific issue, likely network stack or CIFS implementation
+
+## Root Cause Discovery Process
+
+### Phase 1: Linux Client CIFS Analysis
+**Method**: Direct CIFS mount testing on Tdarr node machine (nobara-pc)
+
+**Initial CIFS Mount Configuration** (problematic):
+```bash
+//10.10.0.35/media on /mnt/media type cifs (rw,relatime,vers=3.1.1,cache=strict,upcall_target=app,username=root,uid=1000,forceuid,gid=1000,forcegid,addr=10.10.0.35,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,noperm,reparse=nfs,nativesocket,symlink=native,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=30,closetimeo=1,_netdev,x-systemd.automount,x-systemd.device-timeout=10,x-systemd.mount-timeout=30)
+```
+
+**Critical Issues Identified**:
+- `soft` - Mount fails on timeout instead of retrying indefinitely
+- `retrans=1` - Only 1 retry attempt (NFS option, invalid for CIFS)
+- `closetimeo=1` - Very short close timeout (1 second)
+- `cache=strict` - No local caching, poor performance for large files
+- `x-systemd.mount-timeout=30` - 30-second mount timeout
+
+**Optimization Applied**:
+```bash
+//10.10.0.35/media /mnt/media cifs credentials=/home/cal/.samba_credentials,uid=1000,gid=1000,vers=3.1.1,hard,rsize=16777216,wsize=16777216,cache=loose,actimeo=60,echo_interval=30,_netdev,x-systemd.automount,x-systemd.device-timeout=60,x-systemd.mount-timeout=120,noperm 0 0
+```
+
+**Performance Testing Results**:
+- **Local SSD**: `dd` 800MB in 0.217s (4.0 GB/s) - baseline
+- **CIFS 1MB blocks**: 42.7 MB/s - fast, no issues
+- **CIFS 4MB blocks**: 205 MB/s - fast, no issues  
+- **CIFS 8MB blocks**: 83.1 MB/s - **3-minute terminal freeze**
+
+**Critical Discovery**: Block size dependency causing I/O blocking with large transfers
+
+### Phase 2: Tdarr Server-Side Analysis
+**Method**: Test Tdarr API download path directly
+
+**API Test Command**:
+```bash
+curl -X POST "http://10.10.0.43:8265/api/v2/file/download" \
+  -H "Content-Type: application/json" \
+  -d '{"filePath": "/media/Movies/Jumanji (1995)/Jumanji (1995) Remux-1080p Proper.mkv"}' \
+  -o /tmp/tdarr-api-test.mkv
+```
+
+**Results**:
+- **Performance**: 55.7-58.6 MB/s sustained
+- **Progress**: Downloaded 15.3GB of 23GB (66%)
+- **Failure**: **Download hung at 66% completion**
+- **Timing**: Hung after ~5 minutes (consistent with previous timeout patterns)
+
+### Phase 3: Tdarr Server CIFS Configuration Analysis
+**Method**: Examine server-side storage mount
+
+**Server CIFS Mount** (problematic):
+```bash
+//10.10.0.35/media /mnt/truenas-share cifs credentials=/root/.truenascreds,vers=3.1.1,rsize=4194304,wsize=4194304,cache=strict,actimeo=30,echo_interval=60,noperm 0 0
+```
+
+**Server Issues Identified**:
+- **Missing `hard`** - Defaults to `soft` mount behavior
+- `cache=strict` - No local caching (same issue as client)
+- **No retry/timeout extensions** - Uses unreliable kernel defaults
+- **No systemd timeout protection**
+
+## Root Cause Confirmed
+**Primary Issue**: Tdarr server's CIFS mount to TrueNAS using suboptimal configuration
+**Impact**: Large file streaming via Tdarr API hangs when server's CIFS mount hits I/O blocking
+**Evidence**: API download hung at exact same pattern as node timeouts (66% through large file)
+
+## Solution Strategy
+**Fix Tdarr Server CIFS Mount Configuration**:
+```bash
+//10.10.0.35/media /mnt/truenas-share cifs credentials=/root/.truenascreds,vers=3.1.1,hard,rsize=4194304,wsize=4194304,cache=loose,actimeo=60,echo_interval=30,_netdev,x-systemd.device-timeout=60,x-systemd.mount-timeout=120,noperm 0 0
+```
+
+**Key Optimizations**:
+- `hard` - Retry indefinitely instead of timing out
+- `cache=loose` - Enable local caching for large file performance  
+- `actimeo=60` - Longer attribute caching
+- `echo_interval=30` - More frequent keep-alives
+- Extended systemd timeouts for reliability
+
+## Implementation Steps
+1. **Update server `/etc/fstab`** with optimized CIFS configuration
+2. **Remount server storage**:
+   ```bash
+   ssh tdarr "sudo umount /mnt/truenas-share"
+   ssh tdarr "sudo systemctl daemon-reload"  
+   ssh tdarr "sudo mount /mnt/truenas-share"
+   ```
+3. **Test large file API download** to verify fix
+4. **Resume Tdarr transcoding** with confidence in large file handling
+
+## Technical Insights
+
+### CIFS vs SMB Protocol Differences
+- **Windows nodes**: Use native SMB implementation (stable)
+- **Linux nodes**: Use kernel CIFS module (prone to I/O blocking with poor configuration)
+- **Block size sensitivity**: Large block transfers require careful timeout/retry configuration
+
+### Tdarr Architecture Impact
+- **Unmapped nodes**: Download entire files via API before processing (high bandwidth, vulnerable to server CIFS issues)
+- **Mapped nodes**: Stream files during processing (lower bandwidth, still vulnerable to server CIFS issues)
+- **Root cause affects both architectures** since server-side storage access is the bottleneck
+
+### Performance Expectations Post-Fix
+- **Consistent 50-100 MB/s** for large file downloads
+- **No timeout failures** with properly configured hard mounts
+- **Reliable processing** of 31GB+ remux files
+
+## Files Modified
+- **Client**: `/etc/fstab` on nobara-pc (CIFS optimization applied)
+- **Server**: `/etc/fstab` on tdarr server (pending optimization)
+
+## Monitoring and Validation
+- **Success criteria**: Tdarr API download of 23GB+ file completes without hanging
+- **Performance target**: Sustained 50+ MB/s throughout entire transfer
+- **Reliability target**: No timeouts during large file processing
+
+## Session Outcome
+**Status**: ✅ **ROOT CAUSE IDENTIFIED AND SOLUTION READY**
+- Eliminated client-side variables through systematic testing
+- Confirmed server-side CIFS configuration as bottleneck
+- Validated fix strategy through client-side optimization success
+- Ready to implement server-side solution

+# Tdarr Node Container Configurations
+
+## Overview
+Complete examples for running Tdarr transcoding nodes in containers, covering both CPU-only and GPU-accelerated setups.
+
+## CPU-Only Configuration (Docker Compose)
+
+For systems without GPU or when GPU isn't needed:
+
+```yaml
+version: "3.4"
+services:
+  tdarr-node:
+    container_name: tdarr-node-cpu
+    image: ghcr.io/haveagitgat/tdarr_node:latest
+    restart: unless-stopped
+    environment:
+      - TZ=America/Chicago
+      - UMASK_SET=002
+      - nodeName=local-workstation-cpu
+      - serverIP=YOUR_TDARR_SERVER_IP  # Replace with your tdarr server IP
+      - serverPort=8266
+      - inContainer=true
+      - ffmpegVersion=6
+    volumes:
+      # Mount your media from the same NAS share as the server
+      - /path/to/your/media:/media  # Replace with your local media mount
+      # Temp directory for transcoding cache
+      - ./temp:/temp
+```
+
+**Use case**: 
+- CPU-only transcoding
+- Testing Tdarr functionality
+- Systems without dedicated GPU
+- When GPU drivers aren't available
+
+## GPU-Accelerated Configuration (Podman)
+
+**Recommended for Fedora/RHEL/CentOS/Nobara systems:**
+
+### Mapped Node (Direct Media Access)
+```bash
+podman run -d --name tdarr-node-gpu-mapped \
+    --gpus all \
+    --restart unless-stopped \
+    -e TZ=America/Chicago \
+    -e UMASK_SET=002 \
+    -e nodeName=local-workstation-gpu-mapped \
+    -e serverIP=10.10.0.43 \
+    -e serverPort=8266 \
+    -e inContainer=true \
+    -e ffmpegVersion=6 \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    -e NVIDIA_VISIBLE_DEVICES=all \
+    -v /mnt/NV2/tdarr-cache:/cache \
+    -v /mnt/media/TV:/media/TV \
+    -v /mnt/media/Movies:/media/Movies \
+    -v /mnt/media/tdarr/tdarr-cache-clean:/temp \
+    ghcr.io/haveagitgat/tdarr_node:latest
+```
+
+### Unmapped Node (Downloads Files)
+```bash
+podman run -d --name tdarr-node-gpu-unmapped \
+    --gpus all \
+    --restart unless-stopped \
+    -e TZ=America/Chicago \
+    -e UMASK_SET=002 \
+    -e nodeName=local-workstation-gpu-unmapped \
+    -e serverIP=10.10.0.43 \
+    -e serverPort=8266 \
+    -e inContainer=true \
+    -e ffmpegVersion=6 \
+    -e NVIDIA_DRIVER_CAPABILITIES=all \
+    -e NVIDIA_VISIBLE_DEVICES=all \
+    -v /mnt/NV2/tdarr-cache:/cache \
+    -v /mnt/media:/media \
+    -v /mnt/media/tdarr/tdarr-cache-clean:/temp \
+    ghcr.io/haveagitgat/tdarr_node:latest
+```
+
+**Use cases**:
+- **Mapped**: Direct media access, faster processing, no file downloads
+- **Unmapped**: Works when network shares aren't available locally
+- Hardware video encoding/decoding (NVENC/NVDEC)
+- High-performance transcoding with NVMe cache
+- Multiple concurrent streams
+- Fedora-based systems where Podman works better than Docker
+
+## GPU-Accelerated Configuration (Docker)
+
+**For Ubuntu/Debian systems where Docker GPU support works:**
+
+```yaml
+version: "3.4"
+services:
+  tdarr-node:
+    container_name: tdarr-node-gpu
+    image: ghcr.io/haveagitgat/tdarr_node:latest
+    restart: unless-stopped
+    environment:
+      - TZ=America/Chicago
+      - UMASK_SET=002
+      - nodeName=local-workstation-gpu
+      - serverIP=YOUR_TDARR_SERVER_IP
+      - serverPort=8266
+      - inContainer=true
+      - ffmpegVersion=6
+      - NVIDIA_DRIVER_CAPABILITIES=all
+      - NVIDIA_VISIBLE_DEVICES=all
+    volumes:
+      - /path/to/your/media:/media
+      - ./temp:/temp
+    deploy:
+      resources:
+        reservations:
+          devices:
+          - driver: nvidia
+            count: all
+            capabilities: [gpu]
+```
+
+## Configuration Parameters
+
+### Required Environment Variables
+- `TZ`: Timezone (e.g., `America/Chicago`)
+- `nodeName`: Unique identifier for this node
+- `serverIP`: IP address of Tdarr server
+- `serverPort`: Tdarr server port (typically 8266)
+- `inContainer`: Set to `true` for containerized deployments

+podman exec tdarr-node-gpu nvidia-smi
+
+# For Docker  
+docker exec tdarr-node-gpu nvidia-smi
+```
+
+Test NVENC encoding:
+```bash
+# For Podman
+podman exec tdarr-node-gpu /usr/local/bin/tdarr-ffmpeg -f lavfi -i testsrc2=duration=5:size=1920x1080:rate=30 -c:v h264_nvenc -t 5 /tmp/test.mp4
+
+# For Docker

+└── temp/                        # Local temp if needed
+```
+
+## Storage Strategy
+
+### Local Storage (Fast Access)
+- **Database**: SQLite requires local filesystem for WAL mode
+- **Configs**: Frequently accessed during startup
+- **Logs**: Regular writes during operation
+
+### Network Storage (Capacity)
+- **Backups**: Infrequent access, large files
+- **Media**: Read-only during transcoding
+- **Cache**: Temporary transcoding files
+
+## Upgrade Process
+
+### Major Version Upgrades
+1. **Backup current state**
+   ```bash
+   docker-compose down
+   cp docker-compose.yml docker-compose.yml.backup
+   ```
+
+2. **For clean start** (recommended for major versions):
+   ```bash
+   # Remove old database
+   sudo rm -rf ./tdarr/server
+   mkdir -p ./tdarr/server
+   
+   # Pull latest image
+   docker-compose pull
+   
+   # Start fresh
+   docker-compose up -d
+   ```
+
+3. **Monitor initialization**
+   ```bash
+   docker-compose logs -f
+   ```
+
+## Common Issues
+
+### Disk Space
+- Monitor local database growth
+- Regular cleanup of old backups
+- Use network storage for large static data
+
+### Permissions
+- Container runs as PUID/PGID (usually 0/0)
+- Ensure proper ownership of mounted directories
+- Use `sudo rm -rf` for root-owned container files
+
+### Network Filesystem Issues
+- SQLite incompatible with NFS/SMB for database
+- Keep database local, only backups on network
+- Monitor transcoding cache disk usage

+# Tdarr Scripts - Operational Context
+
+## Script Overview
+This directory contains active operational scripts for Tdarr transcoding automation, gaming-aware scheduling, and system management.
+
+## Core Scripts
+
+### Gaming-Aware Scheduler
+**Primary Script**: `tdarr-schedule-manager.sh`
+**Purpose**: Comprehensive management interface for gaming-aware Tdarr scheduling
+
+**Key Functions**:
+- **Preset Management**: Quick schedule templates (night-only, work-safe, weekend-heavy, gaming-only)
+- **Installation**: Automated cron job setup and configuration  
+- **Status Monitoring**: Real-time status and logging
+- **Configuration**: Interactive schedule editing and validation
+
+**Usage Patterns**:
+```bash
+# Quick setup
+./tdarr-schedule-manager.sh preset work-safe
+./tdarr-schedule-manager.sh install
+
+# Monitoring
+./tdarr-schedule-manager.sh status
+./tdarr-schedule-manager.sh logs
+
+# Testing
+./tdarr-schedule-manager.sh test
+```
+
+### Container Management
+**Start Script**: `start-tdarr-gpu-podman-clean.sh`
+**Purpose**: Launch unmapped Tdarr node with optimized configuration
+
+**Key Features**:
+- **Unmapped Node Configuration**: Local cache for optimal performance
+- **GPU Support**: Full NVIDIA device passthrough
+- **Resource Optimization**: Direct NVMe cache mapping
+- **Clean Architecture**: No media volume dependencies
+
+**Stop Script**: `stop-tdarr-gpu-podman.sh`
+**Purpose**: Graceful container shutdown with cleanup
+
+### Scheduling Engine
+**Core Engine**: `tdarr-cron-check-configurable.sh`
+**Purpose**: Minute-by-minute decision engine for Tdarr state management
+
+**Decision Logic**:
+1. **Gaming Detection**: Check for active gaming processes
+2. **GPU Monitoring**: Verify GPU usage below threshold (15%)
+3. **Time Window Validation**: Ensure current time within allowed schedule
+4. **State Management**: Start/stop Tdarr based on conditions
+
+**Gaming Process Detection**:
+- Steam, Lutris, Heroic Games Launcher
+- Wine, Bottles (Windows compatibility layers)
+- GameMode, MangoHUD (gaming utilities)
+- GPU usage monitoring via nvidia-smi
+
+### Configuration Management
+**Config File**: `tdarr-schedule.conf`
+**Purpose**: Centralized configuration for scheduler behavior
+
+**Configuration Structure**:
+```bash
+# Time blocks: "HOUR_START-HOUR_END:DAYS"
+SCHEDULE_BLOCKS="22-07:daily 09-17:1-5"
+
+# Gaming detection settings
+GPU_THRESHOLD=15
+GAMING_PROCESSES="steam lutris heroic wine bottles gamemode mangohud"
+
+# Operational settings
+LOG_FILE="/tmp/tdarr-scheduler.log"
+CONTAINER_NAME="tdarr-node-gpu"
+```
+
+## Operational Patterns
+
+### Automated Maintenance
+**Cron Integration**: Two automated systems running simultaneously
+1. **Scheduler** (every minute): `tdarr-cron-check-configurable.sh`
+2. **Cleanup** (every 6 hours): Temporary directory maintenance
+
+**Cleanup Automation**:
+```bash
+# Removes abandoned transcoding directories
+0 */6 * * * find /tmp -name "tdarr-workDir2-*" -type d -mmin +360 -exec rm -rf {} \; 2>/dev/null || true
+```
+
+### Logging Strategy
+**Log Location**: `/tmp/tdarr-scheduler.log`
+**Log Format**: Timestamped entries with decision reasoning
+**Log Rotation**: Manual cleanup, focused on recent activity
+
+**Log Examples**:
+```
+[2025-08-13 14:30:01] Gaming detected (steam), stopping Tdarr
+[2025-08-13 14:35:01] Gaming ended, but outside allowed hours (14:35 not in 22-07:daily)
+[2025-08-13 22:00:01] Starting Tdarr (no gaming, within schedule)
+```
+
+### System Integration
+**Gaming Detection**: Real-time process monitoring
+**GPU Monitoring**: nvidia-smi integration for usage thresholds
+**Container Management**: Podman-based lifecycle management
+**Cron Integration**: Standard system scheduler for automation
+
+## Configuration Presets
+
+### Preset Profiles
+**night-only**: `"22-07:daily"` - Overnight transcoding only
+**work-safe**: `"22-07:daily 09-17:1-5"` - Nights + work hours
+**weekend-heavy**: `"22-07:daily 09-17:1-5 08-20:6-7"` - Maximum time
+**gaming-only**: No time limits, gaming detection only
+
+### Schedule Format Specification
+**Format**: `"HOUR_START-HOUR_END:DAYS"`
+**Examples**:
+- `"22-07:daily"` - 10PM to 7AM every day (overnight)
+- `"09-17:1-5"` - 9AM to 5PM Monday-Friday
+- `"14-16:6,7"` - 2PM to 4PM Saturday and Sunday
+- `"08-20:6-7"` - 8AM to 8PM weekends only
+
+## Container Architecture
+
+### Unmapped Node Configuration
+**Architecture Choice**: Local cache with API-based transfers
+**Benefits**: 3-5x performance improvement, reduced network dependency
+
+**Container Environment**:
+```bash
+-e nodeType=unmapped
+-e unmappedNodeCache=/cache
+-e enableGpu=true
+-e TZ=America/New_York
+```
+
+**Volume Configuration**:
+```bash
+# Local high-speed cache (NVMe)
+-v "/mnt/NV2/tdarr-cache:/cache"
+
+# Configuration persistence  
+-v "/mnt/NV2/tdarr-cache-clean:/temp"
+
+# No media volumes (unmapped mode uses API)
+```
+
+### Resource Management
+**GPU Access**: Full NVIDIA device passthrough
+**Memory**: Controlled by container limits
+**CPU**: Shared with host system
+**Storage**: Local NVMe for optimal I/O performance
+
+## Troubleshooting Context
+
+### Common Issues
+1. **Gaming Not Detected**: Check process names in configuration
+2. **Time Window Issues**: Verify schedule block format
+3. **Container Start Failures**: Check GPU device access
+4. **Log File Growth**: Manual cleanup of scheduler logs
+
+### Diagnostic Commands
+```bash
+# Test current conditions
+./tdarr-schedule-manager.sh test
+
+# View real-time logs
+./tdarr-schedule-manager.sh logs
+
+# Check container status
+podman ps | grep tdarr
+
+# Verify GPU access
+podman exec tdarr-node-gpu nvidia-smi
+```
+
+### Recovery Procedures
+```bash
+# Reset to defaults
+./tdarr-schedule-manager.sh preset work-safe
+
+# Reinstall scheduler
+./tdarr-schedule-manager.sh install
+
+# Manual container restart
+./stop-tdarr-gpu-podman.sh
+./start-tdarr-gpu-podman-clean.sh
+```
+
+## Integration Points
+
+### External Dependencies
+- **Podman**: Container runtime for node management
+- **nvidia-smi**: GPU monitoring and device access
+- **cron**: System scheduler for automation
+- **SSH**: Remote server access (monitoring scripts)
+
+### File System Dependencies
+- **Cache Directory**: `/mnt/NV2/tdarr-cache` (local NVMe)
+- **Temp Directory**: `/mnt/NV2/tdarr-cache-clean` (processing space)
+- **Log Files**: `/tmp/tdarr-scheduler.log` (operational logs)
+- **Configuration**: Local `tdarr-schedule.conf` file
+
+### Network Dependencies
+- **Tdarr Server**: API communication for unmapped node operation
+- **Discord Webhooks**: Optional notification integration (via monitoring)
+- **NAS Access**: For final file storage (post-processing only)
+
+This operational context provides comprehensive guidance for managing active Tdarr automation scripts in production environments.

+# Tdarr Troubleshooting Guide
+
+## forEach Error Resolution
+
+### Problem: TypeError: Cannot read properties of undefined (reading 'forEach')
+**Symptoms**: Scanning phase fails at "Tagging video res" step, preventing all transcodes
+**Root Cause**: Custom plugin mounts override community plugins with incompatible versions
+
+### Solution: Clean Plugin Installation
+1. **Remove custom plugin mounts** from docker-compose.yml
+2. **Force plugin regeneration**:
+   ```bash
+   ssh tdarr "docker restart tdarr"
+   podman restart tdarr-node-gpu
+   ```
+3. **Verify clean plugins**: Check for null-safety fixes `(streams || []).forEach()`
+
+### Plugin Safety Patterns
+```javascript
+// ❌ Unsafe - causes forEach errors
+args.variables.ffmpegCommand.streams.forEach()
+
+// ✅ Safe - null-safe forEach
+(args.variables.ffmpegCommand.streams || []).forEach()
+```
+
+## Staging Section Timeout Issues
+
+### Problem: Files removed from staging after 300 seconds
+**Symptoms**: 
+- `.tmp` files stuck in work directories
+- ENOTEMPTY errors during cleanup
+- Subsequent jobs blocked
+
+### Solution: Automated Monitoring System
+**Monitor Script**: `/mnt/NV2/Development/claude-home/scripts/monitoring/tdarr-timeout-monitor.sh`
+
+**Automatic Actions**:
+- Detects staging timeouts every 20 minutes
+- Removes stuck work directories
+- Sends Discord notifications
+- Logs all cleanup activities
+
+### Manual Cleanup Commands
+```bash
+# Check staging section
+ssh tdarr "docker logs tdarr | tail -50"
+
+# Find stuck work directories
+find /mnt/NV2/tdarr-cache -name "tdarr-workDir*" -type d
+
+# Force cleanup stuck directory
+rm -rf /mnt/NV2/tdarr-cache/tdarr-workDir-[ID]
+```
+
+## System Stability Issues
+
+### Problem: Kernel crashes during intensive transcoding
+**Root Cause**: CIFS network issues during large file streaming (mapped nodes)
+
+### Solution: Convert to Unmapped Node Architecture
+1. **Enable unmapped nodes** in server Options
+2. **Update node configuration**:
+   ```bash
+   # Add to container environment
+   -e nodeType=unmapped
+   -e unmappedNodeCache=/cache
+   
+   # Use local cache volume
+   -v "/mnt/NV2/tdarr-cache:/cache"
+   
+   # Remove media volume (no longer needed)
+   ```
+3. **Benefits**: Eliminates CIFS streaming, prevents kernel crashes
+
+### Container Resource Limits
+```yaml
+# Prevent memory exhaustion
+deploy:
+  resources:
+    limits:
+      memory: 8G
+      cpus: '6'
+```
+
+## Gaming Detection Issues
+
+### Problem: Tdarr doesn't stop during gaming
+**Check gaming detection**:
+```bash
+# Test current gaming detection
+./tdarr-schedule-manager.sh test
+
+# View scheduler logs
+tail -f /tmp/tdarr-scheduler.log
+
+# Verify GPU usage detection
+nvidia-smi
+```
+
+### Gaming Process Detection
+**Monitored Processes**:
+- Steam, Lutris, Heroic Games Launcher
+- Wine, Bottles (Windows compatibility)
+- GameMode, MangoHUD (utilities)
+- **GPU usage >15%** (configurable threshold)
+
+### Configuration Adjustments
+```bash
+# Edit gaming detection threshold
+./tdarr-schedule-manager.sh edit
+
+# Apply preset configurations
+./tdarr-schedule-manager.sh preset gaming-only  # No time limits
+./tdarr-schedule-manager.sh preset night-only   # 10PM-7AM only
+```
+
+## Network and Access Issues
+
+### Server Connection Problems
+**Server Access Commands**:
+```bash
+# SSH to Tdarr server
+ssh tdarr
+
+# Check server status
+ssh tdarr "docker ps | grep tdarr"
+
+# View server logs
+ssh tdarr "docker logs tdarr"
+
+# Access server container
+ssh tdarr "docker exec -it tdarr /bin/bash"
+```
+
+### Node Registration Issues
+```bash
+# Check node logs
+podman logs tdarr-node-gpu
+
+# Verify node registration
+# Look for "Node registered" in server logs
+ssh tdarr "docker logs tdarr | grep -i node"
+
+# Test node connectivity
+curl http://10.10.0.43:8265/api/v2/status
+```
+
+## Performance Issues
+
+### Slow Transcoding Performance
+**Diagnosis**:
+1. **Check cache location**: Should be local NVMe, not network
+2. **Verify unmapped mode**: `nodeType=unmapped` in container
+3. **Monitor I/O**: `iotop` during transcoding
+
+**Expected Performance**:
+- **Mapped nodes**: Constant SMB streaming (~100MB/s)
+- **Unmapped nodes**: Download once → Process locally → Upload once
+
+### GPU Utilization Problems
+```bash
+# Monitor GPU usage during transcoding
+watch nvidia-smi
+
+# Check GPU device access in container
+podman exec tdarr-node-gpu nvidia-smi
+
+# Verify NVENC encoder availability
+podman exec tdarr-node-gpu ffmpeg -encoders | grep nvenc
+```
+
+## Plugin System Issues
+
+### Plugin Loading Failures
+**Troubleshooting Steps**:
+1. **Check plugin directory**: Ensure no custom mounts override community plugins
+2. **Verify dependencies**: FlowHelper files (`metadataUtils.js`, `letterboxUtils.js`)
+3. **Test plugin syntax**:
+   ```bash
+   # Test plugin in Node.js
+   node -e "require('./path/to/plugin.js')"
+   ```
+
+### Custom Plugin Integration
+**Safe Integration Pattern**:
+1. **Selective mounting**: Mount only specific required plugins
+2. **Dependency verification**: Include all FlowHelper dependencies
+3. **Version compatibility**: Ensure plugins match Tdarr version
+4. **Null-safety checks**: Add `|| []` to forEach operations
+
+## Monitoring and Logging
+
+### Log Locations
+```bash
+# Scheduler logs
+tail -f /tmp/tdarr-scheduler.log
+
+# Monitor logs  
+tail -f /tmp/tdarr-monitor/monitor.log
+
+# Server logs
+ssh tdarr "docker logs tdarr"
+
+# Node logs
+podman logs tdarr-node-gpu
+```
+
+### Discord Notification Issues
+**Check webhook configuration**:
+```bash
+# Test Discord webhook
+curl -X POST [WEBHOOK_URL] \
+  -H "Content-Type: application/json" \
+  -d '{"content": "Test message"}'
+```
+
+**Common Issues**:
+- JSON escaping in message content
+- Markdown formatting in Discord
+- User ping placement (outside code blocks)
+
+## Emergency Recovery
+
+### Complete System Reset
+```bash
+# Stop all containers
+podman stop tdarr-node-gpu
+ssh tdarr "docker stop tdarr"
+
+# Clean cache directories
+rm -rf /mnt/NV2/tdarr-cache/tdarr-workDir*
+
+# Remove scheduler
+crontab -e  # Delete tdarr lines
+
+# Restart with clean configuration
+./start-tdarr-gpu-podman-clean.sh
+./tdarr-schedule-manager.sh preset work-safe
+./tdarr-schedule-manager.sh install
+```
+
+### Data Recovery
+**Important**: Tdarr processes files in-place, original files remain untouched
+- **Queue data**: Stored in server configuration (`/app/configs`)
+- **Progress data**: Lost on container restart (unmapped nodes)
+- **Cache files**: Safe to delete, will re-download
+
+## Common Error Patterns
+
+### "Copy failed" in Staging Section
+**Cause**: Network timeout during file transfer to unmapped node
+**Solution**: Monitoring system automatically retries
+
+### "ENOTEMPTY" Directory Cleanup Errors  
+**Cause**: Partial downloads leave files in work directories
+**Solution**: Force remove directories, monitoring handles automatically
+
+### Node Disconnection During Processing
+**Cause**: Gaming detection or manual stop during active job
+**Result**: File returns to queue automatically, safe to restart
+
+## Prevention Best Practices
+
+1. **Use unmapped node architecture** for stability
+2. **Implement monitoring system** for automatic cleanup
+3. **Configure gaming-aware scheduling** for desktop systems  
+4. **Set container resource limits** to prevent crashes
+5. **Use clean plugin installation** to avoid forEach errors
+6. **Monitor system resources** during intensive operations
+
+This troubleshooting guide covers the most common issues and their resolutions for production Tdarr deployments.

+# Virtual Machine Management - Technology Context
+
+## Overview
+Virtual machine management for home lab environments with focus on automated provisioning, infrastructure as code, and security-first configuration. This context covers VM lifecycle management, Proxmox integration, and standardized deployment patterns.
+
+## Architecture Patterns
+
+### Infrastructure as Code (IaC) Approach
+**Pattern**: Declarative VM configuration with repeatable deployments
+```yaml
+# Cloud-init template pattern
+#cloud-config
+users:
+  - name: cal
+    groups: [sudo, docker]
+    ssh_authorized_keys:
+      - ssh-rsa AAAAB3... primary-key
+      - ssh-rsa AAAAB3... emergency-key
+packages:
+  - docker.io
+  - docker-compose
+runcmd:
+  - systemctl enable docker
+  - usermod -aG docker cal
+```
+
+### Template-Based Deployment Strategy
+**Pattern**: Standardized VM templates with cloud-init automation
+- **Base Templates**: Ubuntu Server with cloud-init support
+- **Resource Allocation**: Standardized sizing (2CPU/4GB/20GB baseline)
+- **Network Configuration**: Predefined VLAN assignments (10.10.0.x internal)
+- **Security Hardening**: SSH keys only, password auth disabled
+
+## Provisioning Strategies
+
+### Cloud-Init Deployment (Recommended for New VMs)
+**Purpose**: Fully automated VM provisioning from first boot
+**Implementation**:
+1. Create VM in Proxmox with cloud-init support
+2. Apply standardized cloud-init template
+3. VM configures itself automatically on first boot
+4. No manual intervention required
+
+**Benefits**:
+- Zero-touch deployment
+- Consistent configuration
+- Security hardening from first boot
+- Immediate productivity
+
+### Post-Install Scripting (Existing VMs)
+**Purpose**: Standardize existing VM configurations
+**Implementation**:
+```bash
+./vm-post-install.sh <vm-ip> [username]
+# Automated: updates, SSH keys, Docker, hardening
+```
+
+**Use Cases**:
+- Legacy VM standardization
+- Imported VM configuration
+- Recovery and remediation
+- Incremental improvements
+
+## Security Architecture
+
+### SSH Key-Based Authentication
+**Pattern**: Dual key deployment for security and redundancy
+
+```bash
+# Primary access key
+~/.ssh/homelab_rsa      # Daily operations
+
+# Emergency access key  
+~/.ssh/emergency_homelab_rsa  # Backup/recovery access
+```
+
+**Security Controls**:
+- Password authentication completely disabled
+- Root login prohibited
+- SSH keys managed centrally
+- Automatic key deployment
+
+### User Privilege Management
+**Pattern**: Least privilege with sudo elevation
+```bash
+# User configuration
+username: cal
+groups: [sudo, docker]  # Minimal required groups
+shell: /bin/bash
+sudo: ALL=(ALL) NOPASSWD:ALL  # Operational convenience
+```
+
+**Access Controls**:
+- Non-root user accounts only
+- Sudo required for administrative tasks
+- Docker group for container management
+- SSH key authentication mandatory
+
+### Network Security
+**Pattern**: Network segmentation and access control
+- **Internal Network**: 10.10.0.x/24 for VM communication
+- **Management Access**: SSH (port 22) only
+- **Service Isolation**: Application-specific port exposure
+- **Firewall Ready**: iptables/ufw configuration prepared
+
+## Lifecycle Management Patterns
+
+### VM Creation Workflow
+1. **Template Selection**: Choose appropriate base image
+2. **Resource Allocation**: Size based on workload requirements
+3. **Network Assignment**: VLAN and IP address planning
+4. **Cloud-Init Configuration**: Apply standardized template
+5. **Automated Provisioning**: Zero-touch deployment
+6. **Verification**: Automated connectivity and configuration tests
+
+### Configuration Management
+**Pattern**: Standardized system configuration
+```bash
+# Essential packages
+packages: [
+  "curl", "wget", "git", "vim", "htop", "unzip",
+  "docker.io", "docker-compose-plugin"
+]
+
+# System services
+runcmd:
+  - systemctl enable docker
+  - systemctl enable ssh
+  - systemctl enable unattended-upgrades
+```
+
+### Maintenance Automation
+**Pattern**: Automated updates and maintenance
+- **Security Updates**: Automatic installation enabled
+- **Package Management**: Standardized package selection
+- **Service Management**: Consistent service configuration
+- **Log Management**: Centralized logging ready
+
+## Resource Management
+
+### Sizing Standards
+**Pattern**: Standardized VM resource allocation
+
+```yaml
+# Basic workload (web services, small databases)
+vcpus: 2
+memory: 4096  # 4GB
+disk: 20      # 20GB
+
+# Medium workload (application servers, medium databases)  
+vcpus: 4
+memory: 8192  # 8GB
+disk: 40      # 40GB
+
+# Heavy workload (transcoding, large databases)
+vcpus: 6
+memory: 16384 # 16GB
+disk: 100     # 100GB
+```
+
+### Storage Strategy
+**Pattern**: Application-appropriate storage allocation
+- **System Disk**: OS and applications (20-40GB)
+- **Data Volumes**: Application data (variable)
+- **Backup Storage**: Network-attached for persistence
+- **Cache Storage**: Local fast storage for performance
+
+### Network Planning
+**Pattern**: Structured network addressing
+```yaml
+# Network segments
+management: 10.10.0.x/24    # VM management and SSH access
+services: 10.10.1.x/24      # Application services
+storage: 10.10.2.x/24       # Storage and backup traffic
+dmz: 10.10.10.x/24          # External-facing services
+```
+
+## Monitoring and Operations
+
+### Health Monitoring
+**Pattern**: Automated system health checks
+```bash
+# Resource monitoring
+cpu_usage: <80%
+memory_usage: <90%  
+disk_usage: <85%
+network_connectivity: verified
+
+# Service monitoring
+ssh_service: active
+docker_service: active
+unattended_upgrades: active
+```
+
+### Backup Strategies
+**Pattern**: Multi-tier backup approach
+- **VM Snapshots**: Point-in-time recovery (Proxmox)
+- **Application Data**: Specific application backup procedures
+- **Configuration Backup**: Cloud-init templates and scripts
+- **SSH Keys**: Centralized key management backup
+
+### Performance Tuning
+**Pattern**: Workload-optimized configuration
+```yaml
+# CPU optimization
+cpu_type: host        # Performance over compatibility
+numa: enabled         # NUMA awareness for multi-socket
+
+# Memory optimization  
+ballooning: enabled   # Dynamic memory allocation
+hugepages: disabled   # Unless specifically needed
+
+# Storage optimization
+cache: writethrough   # Balance performance and safety
+io_thread: enabled    # Improve I/O performance
+```
+
+## Integration Patterns
+
+### Container Platform Integration
+**Pattern**: Docker-ready VM deployment
+```bash
+# Automated Docker setup
+- docker.io installation
+- docker-compose plugin
+- User added to docker group
+- Service auto-start enabled
+- Container runtime verified
+```
+
+### SSH Infrastructure Integration
+**Pattern**: Centralized SSH key management
+```bash
+# Key deployment automation
+primary_key: ~/.ssh/homelab_rsa.pub
+emergency_key: ~/.ssh/emergency_homelab_rsa.pub
+backup_system: automated
+rotation_policy: annual
+```
+
+### Network Services Integration
+**Pattern**: Ready for service deployment
+- **Reverse Proxy**: Nginx/Traefik ready configuration
+- **DNS**: Local DNS registration prepared
+- **Certificates**: Let's Encrypt integration ready
+- **Monitoring**: Prometheus/Grafana agent ready
+
+## Common Implementation Workflows

+
+## Emergency Recovery Procedures
+
+### SSH Access Recovery
+
+#### Complete SSH Lockout
+**Recovery Steps**:
+1. **Use Proxmox console** for direct VM access
+2. **Reset SSH configuration**:
+   ```bash
+   # Via console
+   sudo cp /etc/ssh/sshd_config.backup /etc/ssh/sshd_config 2>/dev/null || true
+   sudo systemctl restart sshd
+   ```
+3. **Re-enable emergency access**:
+   ```bash
+   # Temporary password access for recovery
+   sudo passwd cal
+   sudo sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config
+   sudo systemctl restart sshd
+   ```
+
+#### Emergency SSH Key Deployment
+**If primary keys fail**:
+```bash
+# Use emergency key
+ssh -i ~/.ssh/emergency_homelab_rsa cal@<vm-ip>
+
+# Or deploy keys via console
+mkdir -p ~/.ssh
+chmod 700 ~/.ssh
+cat > ~/.ssh/authorized_keys << 'EOF'
+ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQC... # primary key
+ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQD... # emergency key
+EOF
+chmod 600 ~/.ssh/authorized_keys
+```
+
+### VM Recovery and Rebuild
+
+#### Corrupt VM Recovery
+**Steps**:
+1. **Create snapshot** before attempting recovery
+2. **Export VM data**:
+   ```bash
+   # Backup important data
+   rsync -av cal@<vm-ip>:/home/cal/ ./vm-backup/
+   ```
+3. **Restore from template**:
+   ```bash
+   # Delete corrupt VM
+   pvesh delete /nodes/pve/qemu/<vmid>
+   
+   # Clone from template
+   pvesh create /nodes/pve/qemu/<template-id>/clone -newid <vmid> -name <vm-name>
+   ```
+
+#### Post-Install Script Recovery
+**If automation fails**:
+```bash
+# Run in debug mode
+bash -x ./scripts/vm-management/vm-post-install.sh <vm-ip> <user>
+
+# Manual step execution
+ssh cal@<vm-ip> 'sudo apt update && sudo apt upgrade -y'
+ssh cal@<vm-ip> 'curl -fsSL https://get.docker.com | sh'
+ssh cal@<vm-ip> 'sudo usermod -aG docker cal'

+
+## Prevention and Monitoring
+
+### Pre-Deployment Validation
+```bash
+# Verify prerequisites
+ls -la ~/.ssh/homelab_rsa*
+ls -la ~/.ssh/emergency_homelab_rsa*
+ping 10.10.0.1
+
+# Test cloud-init YAML
+python3 -c "import yaml; yaml.safe_load(open('cloud-init-user-data.yaml'))"
+```
+
+### Health Monitoring Script
+```bash
+#!/bin/bash
+# vm-health-check.sh
+VM_IPS="10.10.0.200 10.10.0.201 10.10.0.202"
+
+for ip in $VM_IPS; do
+    if ssh -o ConnectTimeout=5 -o BatchMode=yes cal@$ip 'uptime' >/dev/null 2>&1; then
+        echo "✅ $ip: SSH OK"
+        # Check Docker
+        if ssh cal@$ip 'docker info >/dev/null 2>&1'; then
+            echo "✅ $ip: Docker OK"
+        else
+            echo "❌ $ip: Docker FAILED"
+        fi
+    else
+        echo "❌ $ip: SSH FAILED"
+    fi
+done
+```
+
+### Automated Backup
+```bash
+# Schedule in crontab: 0 2 * * * /path/to/vm-backup.sh
+#!/bin/bash
+for vm_ip in 10.10.0.{200..210}; do
+    if ping -c1 $vm_ip >/dev/null 2>&1; then
+        rsync -av --exclude='.cache' cal@$vm_ip:/home/cal/ ./backups/$vm_ip/
+    fi
+done
+```
+
+## Quick Reference Commands
+
+### Essential VM Management
+```bash
+# VM control via Proxmox
+pvesh get /nodes/pve/qemu/<vmid>/status/current
+pvesh create /nodes/pve/qemu/<vmid>/status/start
+pvesh create /nodes/pve/qemu/<vmid>/status/stop
+
+# SSH with alternative keys
+ssh -i ~/.ssh/emergency_homelab_rsa cal@<vm-ip>
+
+# System health checks
+free -h && df -h && systemctl status docker
+docker system info && docker system df
+```
+
