+### Automated Cleanup System (HIGH)
+**Issue**: Disk space exhaustion on Dokploy server causes CI failures
+
+**Components**:
+- [ ] CI workflow cleanup step - prune build cache after each build
+- [ ] Server-side cron job - daily Docker system prune
+- [ ] Disk monitoring - alert at 80% usage via Grafana
+- [ ] Post-deployment cleanup - remove unused resources after stack deploy
+
+**Implementation**:
+```yaml
+# CI workflows (.gitea/workflows/*.yaml)
+- name: Cleanup build artifacts
+  if: always()
+  run: |
+    docker builder prune -f --keep-storage=2GB
+    docker image prune -f --filter "until=24h"
+```
+
+```bash
+# Server cron (/etc/cron.d/docker-cleanup on 10.100.0.20)
+0 4 * * * root docker system prune -f --volumes --filter "until=72h"
+0 4 * * * root docker exec flexinit-runner docker builder prune -f --keep-storage=5GB
+```
+
+### Web-based TUI Support (HIGH)
+**Feature**: Full TUI (Terminal User Interface) support inside the web browser
+
+**Goal**: Enable rich terminal UI applications (like htop, lazygit, OpenCode TUI mode) to render correctly in the browser-based terminal.
+
+**Components**:
+- [ ] xterm.js integration with full TUI support (colors, mouse, resize)
+- [ ] Proper TERM environment configuration (xterm-256color)
+- [ ] Mouse event passthrough for TUI interactions
+- [ ] Font/rendering optimization for box-drawing characters
+- [ ] Keyboard shortcut handling (Ctrl+C, Ctrl+Z, etc.)
+
+**Technical Options**:
+1. **Upgrade ttyd** - Ensure latest version with full xterm.js features
+2. **Custom xterm.js wrapper** - More control over terminal emulation
+3. **Gotty alternative** - Consider other web terminal solutions
+
+**Use Cases**:
+- OpenCode TUI mode in browser
+- lazygit, lazydocker
+- htop, btop system monitoring
+- vim/neovim with full features
+- Any ncurses-based application
+
+### Other Next Items
 - [ ] User authentication (protect deployments)
 - [ ] Rate limiting (prevent abuse)
 - [ ] Stack management UI (list/delete stacks)

+
+## Technical Notes
+
+### Disk Space Management
+Server: 10.100.0.20 (97GB total)
+- Docker images: ~10GB
+- Containers: ~1.5GB
+- Volumes: ~30GB
+- Build cache: Up to 6GB between cleanups
+- **Safe threshold**: Keep 15GB+ free (85% max usage)
+
+### Key Infrastructure
+- Gitea: git.app.flexinit.nl (repo: flexinit/agent-stack)
+- Runner: flexinit-runner container on 10.100.0.20
+- Registry: git.app.flexinit.nl/flexinit/agent-stack:latest
+- Monitoring: logs.intra.flexinit.nl (dashboard: /d/ai-stack-overview)
