🦉 Die Krümel-Philosophie

"Schnell, native und lesbar für Mensch und Maschine.
Nur ein Krümel, aber das Tor und ein Auge zur Waldwelt." 🥖🌲

Was ist CrumbForest RC1?

Ein schlankes Hardware-Inventar-System für Datacenter Asset Management:

Unit Tests: 100% pass rate (schema, hierarchy, IP allocation, connections)

Migration 003: Datacenter Views

-- 7 SQL Views for asset visualization:
1. view_network_topology      - Recursive hierarchy tree
2. view_datacenter_assets      - Complete asset overview
3. view_rack_layout            - Physical rack organization

- Mobile (<768px): Compact view, essential info only
- Tiny (<480px): Ultra-compact, hide rack info

View Toggle Feature:
- 3-state button: 📱 Mobile → 🖥️ Desktop → ↔️ Auto
- Force view mode on tablets (user choice)
- CSS classes: .force-mobile, .force-desktop
- Instant switching without reload

- Code Coverage: 36.23% (Config: 95%, Auth: 77%)

Test Structure:

./vendor/bin/phpunit                    # All tests
./vendor/bin/phpunit --testsuite Unit   # Fast, no DB
./vendor/bin/phpunit --testsuite Integration  # With DB

📚 Documentation

Updated CLAUDE.md:
- Database Migrations section (manual process)
- Network Topology documentation
- Dev Tools (doktor-crumbforest.sh, macos-setup.sh)
- Deployment workflow with migrations
- Architecture overview

🎯 Design Philosophy: "Naked"

Was bedeutet "Naked"?

bash → php → mysql → backend → vanilla → simple → export

  1. bash first: Setup via Shell Scripts (doktor-setup.sh)
  2. php: Native PHP 8.5+ on LAMP stack, strict types only
  3. mysql: Direct MySQL/MariaDB with PDO, no ORM abstraction
  4. backend: API-first design, all endpoints in single router file
  5. vanilla: Zero frontend build process, pure HTML/CSS/JS
  6. simple: No containers, no webpack, no complexity layers
  7. export: Ultimate goal is Netbox synchronization

Warum "Naked"?

Anti-Docker, Anti-Modern-Framework Ansatz:

❌ Entfernt:
- Docker containers & docker-compose
- SQLite support
- Auto-migrations & complex tooling
- Node.js & npm
- Webpack & build processes
- React/Vue/Angular frameworks
- D3.js & heavy visualization libs

✅ Hinzugefügt:
- Direct LAMP deployment
- Manual database setup
- Simpler file structure
- Vanilla JavaScript
- ASCII visualization
- Pure CSS (no preprocessors)

Ergebnis:

Copy files → configure Apache → import SQL → done

Keine Images zu builden, keine node_modules, keine versteckte Komplexität.
Perfekt für traditionelle Linux Server, RZ-Umgebungen, und Entwickler die jedes bewegliche Teil sehen wollen.
