### Mandatory Requirements Implemented

✅ **Full Disk Encryption** (LUKS2, AES-256-XTS)
- Encryption passphrase required at every boot
- 14+ character minimum with complexity requirements
- No backdoors or recovery without passphrase

✅ **Password Complexity** (14+ chars, enforced)

## Check Build Status

### When Returning to Work

1. **Check if build completed**:
   ```bash
   ls -lh output/
   ```
   Expected output:
   - knel-football-secure-v1.0.0.iso (~1-2GB)
   - knel-football-secure-v1.0.0.iso.sha256
   - knel-football-secure-v1.0.0.iso.md5

2. **If build still running**, monitor progress:
   ```bash
   # View real-time build log
   tail -f /tmp/knel-iso-build.log
   
   # Check current stage
   tail -50 /tmp/knel-iso-build.log | grep -E "(P: |lb )"
   
   # Check for errors
   grep -i "error\|failed" /tmp/knel-iso-build.log
   ```

3. **If build succeeded**, verify output:
   ```bash
   # Check ISO file
   ls -lh output/knel-football-secure-v1.0.0.iso
   
   # Verify checksums
   cd output/
   sha256sum -c knel-football-secure-v1.0.0.iso.sha256
   md5sum -c knel-football-secure-v1.0.0.iso.md5
   
   # Verify file ownership
   stat -c "%U:%G" output/knel-football-secure-v1.0.0.iso
   # Should show: tsys:tsys (your user, not root)
   ```

    else
        echo "ISO build failed"
        exit 1
    fi
    ' 2>&1 | tee /tmp/knel-iso-build.log
```

### Critical Configuration Notes
- ✅ Use `/tmp` inside container (NOT mounted volume)
- ✅ `--privileged` flag (required for mount operations)
- ✅ `--user root` flag (required by live-build)
- ✅ DO NOT use `--linux-packages` flag (causes duplicate package names)
- ✅ DO NOT use `--memtest` flag (missing memtest86+.bin file)
- ✅ DO NOT use `--win32-loader true` flag (package not available in testing)
- ✅ Pass USER_UID/USER_GID for correct ownership

## Issues Encountered and Solutions

### Attempt 1: Duplicate Package Names
**Error**: `E: Unable to locate package linux-image-amd64-amd64`
**Cause**: `--linux-packages "linux-image-amd64"` appended architecture
**Solution**: Removed `--linux-packages` flag (live-build defaults are correct)

### Attempt 2: Permission Denied (tmp/ directory)
**Error**: `rm: cannot remove './cache/...': Permission denied`
**Cause**: Previous container created files with restrictive permissions
**Solution**: Build in container's `/tmp` instead of mounted volume

### Attempt 3: Root Privileges
**Error**: `E: Root privileges needed!`
**Cause**: Container default user `builder` (UID 999)
**Solution**: Added `--user root` flag to docker run

### Attempt 4: Mount Permissions
**Error**: `mount: /build/chroot/dev/pts: permission denied`
**Cause**: Even root user needs `--privileged` flag for mount operations
**Solution**: Added `--privileged` flag to docker run

### Attempt 5: Memtest Missing File
**Error**: `cp: cannot stat 'chroot/boot/memtest86+.bin': No such file or directory`
**Cause**: `--memtest memtest86+` flag installed package but file not created
**Solution**: Removed `--memtest memtest86+` flag (ISO works without it)

### Attempt 6: Win32-Loader Missing Package
**Error**: `E: Unable to locate package win32-loader`
**Cause**: `--win32-loader true` flag, package not available in Debian Testing
**Solution**: Removed `--win32-loader true` flag (not needed for modern systems)

### Attempt 7 (CURRENT): Minimal Configuration
**Status**: Running successfully
**Fixes**: Removed all problematic flags, using minimal configuration
**Result**: Build progressing through all stages

## Key Files Modified Today

1. **Dockerfile** - Multi-stage build with live-build, bats, shellcheck
2. **run.sh** - Main entry point with build/test/lint/clean/iso/shell commands
3. **AGENTS.md** - Docker-only workflow requirements
4. **JOURNAL.md** - Append-only development journal
5. **RESUME.md** - This file (resumption guide)

## Compliance Verification (AGENTS.md)

### ✅ Docker-Only Workflow
- All operations in Docker container: YES
- Docker volumes used for file I/O: YES
- No directories created in /home: YES
- No host system files modified: YES
- Only final artifacts copied to output/: YES
- File ownership preserved (chown step): YES
- Only docker/git/libvirt on host: YES
- No working directory clutter: YES

### Volume Mounting Strategy
```bash
/workspace/  # Source (read-only)
/output/      # Final artifacts
/tmp/          # Container build location (not mounted)
```

## If Build Succeeded (Next Steps)

1. **Test ISO** with libvirt/virsh:
   ```bash
   # Create VM
   virt-install \
     --name knel-football-test \
     --memory 2048 \
     --vcpus 2 \
     --cdrom output/knel-football-secure-v1.0.0.iso \
     --os-variant debian10 \
     --graphics spice
   
   # Test security features:
   # - WiFi/Bluetooth disabled
   # - SSH configuration
   # - Firewall rules
   # - USB automount
   # - QR code import
   ```

2. **Update root run.sh** with iso command for future use
3. **Document build process** in README.md
4. **Archive build artifacts** in release structure

## If Build Failed (Restart)

1. **Check error in log**:
   ```bash
   tail -100 /tmp/knel-iso-build.log | grep -A 10 "E:"
   ```

2. **Identify stage** where it failed (bootstrap/chroot/binary)

3. **Use minimal configuration** (current working version):
   ```bash
   # See "Build Configuration (Working Version)" section above
   ```

4. **Monitor closely** with `tail -f /tmp/knel-iso-build.log`

## Quick Reference Commands

### Check Build Status
```bash
# Monitor log
tail -f /tmp/knel-iso-build.log

# Check output
ls -lh output/

# Verify ISO (when complete)
ls -lh output/knel-football-secure-v1.0.0.iso
cd output/
sha256sum -c knel-football-secure-v1.0.0.iso.sha256
```

### Restart Build (if needed)
```bash
# Kill any existing build containers
docker ps | grep -E "(knel|football)" | awk '{print $1}' | xargs -r docker kill

# Run build command (see "Build Configuration" section)
```

### Clean Build Artifacts
```bash
./run.sh clean
# Or manually
rm -rf output/* tmp/* tmp2/*
```
