## ⚠️ READ THESE FILES FIRST
## Overview
### 🚀 Quick Start
1. **AGENTS.md** - Current status + critical requirements (START HERE)
2. **RESUME.md** - Complete resumption guide
3. **QUICK_START.md** - Quick reference commands
KNEL-Football is a highly secure, compliant Debian 13 (Trixie) installation ISO built using a strict Docker-based workflow with Test-Driven Development methodology. The resulting ISO provides a minimal, hardened system with restricted networking designed for tier0 infrastructure access.

## Security Features
### Kernel Module Blacklisting
- WiFi modules: cfg80211, mac80211, brcmfmac, iwlwifi, ath9k, rt73usb
- Bluetooth modules: btusb, bluetooth, btrtl, btintel, btbcm
### Firewall Configuration
- Default deny policy
- Dynamic WireGuard endpoint parsing
- UDP traffic only to WireGuard server
- nftables implementation
### Package Management Security
- Execute permissions removed
- Immutable with `chattr +i`
- APT/DPKG metadata cleared
- No package updates possible
### Boot Security
- UEFI-only boot mode
- Secure Boot enabled
- Measured boot implementation
- Custom keys included
## Compliance
- **CMMC Level 3** - Entry point to tier0 infrastructure
- **FedRAMP LI-SaaS** - Ready for federal government deployment
- **DISA STIG** - Adapted Debian 11 STIG for Debian 13
- **CIS Benchmarks** - Industry best practices for Debian Linux
## User Workflow
### Installation
1. Boot from ISO
2. Complete manual partitioning
3. Set root password
4. Create non-root user (auto-added to sudo)
### Configuration
1. Mount USB drive with WireGuard config
2. Use desktop shortcuts to import/apply configuration
3. QR code scanning available for mobile configuration
### Remote Access
1. Remmina for RDP connections
2. WireGuard tunnel for all network traffic
3. No direct internet access possible
## Development
### Test-Driven Development
- Tests written before implementation
- 100% code coverage mandatory
- BATS framework for testing
- Shellcheck for linting
### Build Environment
- Docker-based container
- No build tools on host
- All dependencies in container
- Proper file permissions
