- Add project directory structure with config, src, tests directories
- Implement run.sh host wrapper script for Docker-based workflow
- Create Dockerfile for build/test environment with live-build
- Add basic live-build configuration with preseed and package lists
- Add .gitignore and .dockerignore files
This establishes the foundation for building the secure Debian ISO.

Implements minimal, secure login without username display:
1. **LightDM Installation**:
- Added lightdm and lightdm-gtk-greeter packages
- Enabled LightDM service by default
- Set default target to graphical
- Removed .xinitrc direct X boot
2. **Minimal and Secure Greeter**:
- Configured /etc/lightdm/lightdm.conf:
* hide-users=true (no username list displayed)
* show-manual-login=true (manual username entry only)
* allow-guest=false (no guest sessions)
* XDMCP disabled (no remote X sessions)
- Greeter shows only:
* Username field (for manual entry)
* Password field
* Login button
- No account picking, no user list
3. **Security Benefits**:
- No user information leaked before authentication
- Attacker cannot enumerate users
- Manual username required (prevents user enumeration)
- Minimal attack surface (LightDM is lightweight)
- No guest sessions (strict access control)
4. **Removed Direct X Boot**:
- No longer booting directly to IceWM via .xinitrc
- Using proper display manager for authentication
- More secure and standardized login process
Files Updated:
- config/preseed.cfg (LightDM packages, enabled service, late_command)
- config/security-config.sh (LightDM configuration, removed .xinitrc)
This implements the "minimal and secure display manager"
requirement with no usernames displayed and no account picking.

Major updates for production-ready ISO:
1. **Debian Version**:
- Updated to Debian 13.3.0 stable (released)
- No longer using testing/sid
- Using debian:stable Docker image
2. **Password Complexity Enforcement**:
- Added libpam-pwquality and libpwquality packages
- Password complexity enforced during install via PAM
- Configured in security-config.sh:
* Minimum 12 characters
* Mixed case required
* At least one digit
* At least one special character
* 3 character classes required
- Preseed enforces password checks during installer
3. **Auto-Lock After 1 Minute**:
- Added xautolock and xscreensaver packages
- Configured in .xinitrc for auto-lock after 1 minute idle
- Uses xscreensaver-command -lock for screen locking
4. **USB Drive Mounting**:
- Added udisks2, gvfs-backends, gvfs-fuse packages
- Created polkit rules for USB mounting
- User added to plugdev and cdrom groups
- USB drives mountable via file manager
5. **WiFi and Bluetooth Disabling**:
- Created config/disable-wifi-bt.sh script
- Blacklists all WiFi kernel modules
- Blacklists all Bluetooth kernel modules
- Masks bluetooth service
- Removes bluez packages
6. **First-Boot Verification**:
- Created scripts/verify-system.sh
- Created config/football-first-boot.service
- Verifies all functional requirements
- Runs once on first boot
- Prevents re-running via status file
7. **ISO Build System**:
- Updated to use Debian 13.3.0 stable ISO
- Scripts and config baked into ISO
- Docker-based build process
- Corrected ISO filename throughout
8. **Preseed Configuration**:
- Manual user creation (not automated)
- Manual password prompts (enforced via PAM)
- Late_command applies all security configs
- Copies verification script to target
- Enables first-boot verification service
Files Added:
- config/disable-wifi-bt.sh (WiFi/BT disabling)
- config/security-config.sh (password complexity, auto-lock, USB mounting)
- config/football-first-boot.service (first-boot verification systemd service)
- scripts/verify-system.sh (comprehensive verification script)
Files Updated:
- config/preseed.cfg (password enforcement, security packages, late_command)
- scripts/build-iso.sh (Debian 13.3.0, correct filenames)
- docs/FUNCTIONAL-REQUIREMENTS.md (verification strategy)
- AGENTS.md (documentation references)
- README.md (documentation references)
All requirements from this session implemented:
✓ Password complexity enforced during install
✓ Auto-lock after 1 minute idle
✓ USB drive mounting enabled
✓ WiFi/Bluetooth disabled
✓ First-boot verification
✓ Scripts baked into ISO (no internet needed)
✓ All packages in ISO
✓ Debian 13.3.0 stable

Adds ISO creation capability for bare metal deployment:
- preseed.cfg: Debian installer automation file
- Automates all installation steps
- User only sets username/password, root password, target disk
- Installs minimal package set
- build-iso.sh: Docker-based ISO build script
- Downloads Debian 13 netboot ISO
- Extracts ISO contents
- Injects preseed configuration
- Creates custom football-installer.iso
- All work done in Docker container
ISO enables easy bare metal deployment with minimal user input.
