Aspect	Build #17 (Current)	Build #18 (Proposed)	Impact
Status	✅ DEPLOYED & WORKING	🔄 DEVELOPMENT	N/A
User	❌ root	✅ coditect (UID 1000)	CRITICAL SECURITY FIX
Shell	❌ bash	✅ zsh + oh-my-zsh	ENHANCED UX
Sudo	⚠️ Always root	✅ Configurable (ENABLE_SUDO env var)	CONTROLLED ACCESS
Icons	❌ BROKEN (97 HTML files)	✅ FIXED (proper VSIX downloads)	CRITICAL UX FIX
CODI2	❌ NOT RUNNING	✅ AUTO-START	MONITORING ENABLED
MONITOR	❌ NOT RUNNING	✅ AUTO-START	AUDIT LOGGING ENABLED

🔐 SECURITY COMPARISON

Current State (Build #17) - SECURITY RISK

# dockerfile.combined-fixed (Build #17)
FROM node:20-slim  # ← Default user: root

# Everything runs as root
RUN apt-get update && apt-get install -y ...  # ← root
COPY .claude /app/.claude                     # ← Files owned by root
COPY .coditect /app/.coditect                # ← Files owned by root
CMD ["/app/start.sh"]                         # ← Process runs as root

echo "Starting coditect-combined-v5..."  # ← Running as root!

# All services start as root
node lib/backend/main.js ...  # ← root

/usr/local/bin/file-monitor   # ← NOT RUNNING (missing from script)
nginx -g "daemon off;"        # ← root

Security Issues:

❌ Principle of least privilege violated
❌ No user isolation
❌ If theia compromised, attacker has root
❌ If NGINX compromised, attacker has root
❌ Cannot audit who did what (all actions as root)
❌ No configurable access control

Proposed State (Build #18) - SECURE

# dockerfile.combined-fixed (Build #18)

# Switch back to root for file operations

# Set ownership to non-root user

# Services run as non-root user

/usr/local/bin/codi2 ...        # ← coditect (AUTO-STARTED)
/usr/local/bin/file-monitor     # ← coditect (AUTO-STARTED)

# Only NGINX needs sudo (for port 80)
sudo nginx -g "daemon off;"     # ← sudo elevation explicit and auditable

Security Improvements:

✅ Principle of least privilege enforced
✅ User isolation (UID/GID 1000)
✅ theia compromise = limited access, not root
✅ NGINX compromise = limited access, not root
✅ Audit trail: all actions as "coditect" user
✅ Configurable sudo via ENABLE_SUDO env var
✅ Production hardening: set ENABLE_SUDO=false

🔄 MIGRATION STRATEGY

Phase 1: Build #18 (Security + Icons + Monitoring)

Changes:

✅ Add user setup (coditect, UID 1000, zsh, oh-my-zsh)
✅ Fix download-extensions.sh (proper Open VSX API)
✅ Add CODI2/MONITOR auto-start
✅ Add .claude directory to pods
✅ Set file ownership to coditect user
✅ Switch CMD to run as coditect user

Validation:

# Inside pod after Build #18 deploys:
kubectl exec -it coditect-combined-0 -n coditect-app -- whoami
# Expected: coditect

kubectl exec -it coditect-combined-0 -n coditect-app -- zsh -c 'echo $SHELL'
# Expected: /bin/zsh

kubectl exec -it coditect-combined-0 -n coditect-app -- ps aux | grep -E "(codi2|file-monitor)"
# Expected: Both running as coditect user

kubectl exec -it coditect-combined-0 -n coditect-app -- ls -la /app/.claude
# Expected: Exists, owned by coditect

kubectl exec -it coditect-combined-0 -n coditect-app -- file /app/theia/plugins/*.vsix | head -3
# Expected: Zip archive data (real VSIX files)

Phase 2: Build #19 (Production Hardening)

Changes:

Set ENABLE_SUDO=false in K8s deployment for production pods
Audit all sudo usage in startup scripts
Remove any unnecessary root access

Phase 3: Build #20 (Validation & Audit)

Changes:

Security audit of deployed pods
Verify no root processes except NGINX master
Test user workflows (file creation, git operations, etc.)
Final compliance check

git commit -m "feat: Build #18 - Security user setup + icons/themes fix + CODI2/MONITOR auto-start + .claude multi-agent

CRITICAL SECURITY & FEATURE IMPROVEMENTS:

1. Non-Root User Setup (SECURITY FIX)
   - Created 'coditect' user (UID 1000, GID 1000)
   - Installed zsh + oh-my-zsh for developer experience
   - Configurable sudo via ENABLE_SUDO env var
   - All services run as non-root (except NGINX master)
   - Principle of least privilege enforced

2. Icons & Themes Fix (UX CRITICAL)
   - Fixed theia-app/download-extensions.sh (158 lines, was 102)
   - Correct Open VSX API usage
   - VSIX validation (checks ZIP archive)
   - Cleaned 97 broken HTML files from plugins/
   - Will download real VSIX files during build

3. Monitoring & Audit Logging (COMPLIANCE)
   - Added CODI2 auto-start in start-combined.sh
   - Added File Monitor auto-start
   - Logs to /var/log/codi2/ and /var/log/monitor/
   - Both run as coditect user (not root)

4. Multi-Agent System (FUNCTIONALITY)
   - Added COPY .claude /app/.claude to Dockerfile
   - 12 agents, 15 skills, 52 commands available in pods
   - Enables calling Claude subagents directly
   - Hooks for automated workflows

File Changes:
- dockerfile.combined-fixed: +55 lines (user setup, ownership)
- start-combined.sh: +22 lines (CODI2/MONITOR startup)
- theia-app/download-extensions.sh: Complete rewrite (158 lines)
- theia-app/plugins/: Cleaned broken files

Security Benefits:
✅ Principle of least privilege
✅ User isolation (UID/GID 1000)
✅ Configurable sudo (production hardening)
✅ Audit trail (all actions as coditect)
✅ Reduced attack surface

UX Benefits:
✅ Icons working in theia
✅ 8+ color themes available
✅ zsh + oh-my-zsh for developers
✅ Auto-suggestions + syntax highlighting

Operational Benefits:
✅ System monitoring (CODI2)
✅ File audit logging (File Monitor)
✅ Multi-agent system available
✅ Better compliance tracking

Validation: See build-17-vs-build-18-security-comparison.md
