### Circular References (Crush Auto-Detection)

**AGENTS.md → RESUME.md**:
- AGENTS.md top section: "⚡ CURRENT STATUS"
- AGENTS.md reference: "⚠️ READ THIS FIRST: RESUME.md"
- Crush sees: Build running status + reference to RESUME.md

**RESUME.md → AGENTS.md**:
- RESUME.md top section: "# ⚡ AGENTS.md contains current status - READ IT FIRST"
- Crush sees: Reference to AGENTS.md for requirements

**README.md → AGENTS.md + RESUME.md**:
- README.md top section: "⚠️ READ THESE FILES FIRST"
- README.md hierarchy: AGENTS.md (START), RESUME.md, QUICK_START.md
- Crush sees: File hierarchy and where to start

### Crush Auto-Start Flow

1. **Crush reads AGENTS.md** (first file checked)
2. **Sees CURRENT STATUS** at top (build running, expected completion)
3. **Sees reference**: "⚠️ READ THIS FIRST: RESUME.md"
4. **Reads RESUME.md** for complete details
5. **Knows exactly where we left off**:
   - Build status (running)
   - Current stage (lb binary_chroot)
   - Expected completion (~15 min)
   - Working configuration (attempt 7, minimal flags)
   - Issues encountered (7 attempts with solutions)
   - Commands to monitor or restart

### Build Status

**Current**: Running successfully (attempt 7, minimal configuration)
- **Started**: 18:04 CST
- **Current Stage**: lb binary_chroot (creating binary filesystem)
- **Expected Completion**: 19:00-19:15 CST
- **Log**: /tmp/knel-iso-build.log
- **Output**: output/knel-football-secure-v1.0.0.iso (when complete)

### First Actions When Returning

```bash
cd /home/tsys/Projects/KNEL/football

# 1. Check if ISO is ready
ls -lh output/

# 2. If ready, verify
cd output/
sha256sum -c knel-football-secure-v1.0.0.iso.sha256

# 3. If not ready, monitor
tail -f /tmp/knel-iso-build.log

# 4. Read complete guide
cat RESUME.md
```

### Compliance Verified (AGENTS.md)

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

### Key Lessons Learned

1. **Default container user matters**: builder (UID 999) needs explicit `--user root`
2. **Privileged flag required**: Even root user needs `--privileged` for mount operations
3. **Volume permissions issue**: Cannot write to mounted volumes from container
4. **Use container /tmp**: Build entirely inside container, not on mounted volume
5. **Minimal config wins**: Remove unnecessary flags to avoid conflicts
6. **Ownership preservation**: Use chown with passed UID/GID environment variables
7. **Document everything**: AGENTS.md + RESUME.md + README.md for easy resumption

### Project Completion Status

**Completed**:
- ✅ Docker build environment (Dockerfile)
- ✅ Root run.sh entry point
- ✅ Docker-only workflow (AGENTS.md compliance)
- ✅ All configuration files
- ✅ Security hardening hooks
- ✅ Custom package lists
- ✅ Desktop environment setup
- ✅ Live-build configuration
- ✅ Append-only JOURNAL.md
- ✅ Comprehensive RESUME.md guide
- ✅ Circular references (Crush auto-detection)

**In Progress**:
- ⏳ ISO build (running in background)
  - Bootstrap: ✅ Complete
  - Chroot: ✅ Complete
  - Binary: ⏳ In progress (15 min remaining)
  - Finalization: ⏳ Pending

**Pending**:
- ⏳ ISO testing with libvirt/virsh
- ⏳ Security feature validation
- ⏳ Documentation finalization
- ⏳ Release preparation

### Next Actions (When Returning)

1. **Check output/** for ISO (ls -lh output/)
2. **Verify ISO** if present (sha256sum -c output/*.sha256)
3. **Monitor build** if not ready (tail -f /tmp/knel-iso-build.log)
4. **Read RESUME.md** for complete details
5. **Test ISO** with libvirt/virsh when ready
6. **Validate security features** in live environment
