+
+### 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
+
