## Phase 1: Performance Optimization (Feb 2026) – 4 Wochen

**Goal:** TUIkit kann große Listen, viele Komponenten und Rapid-Redraws ohne Performance-Degradation handhaben.

### Milestones

#### Week 1: Profiling & Analysis
- [ ] Profile Current Rendering Pipeline
  - Identify bottlenecks in List/Table rendering
  - Measure Re-rendering frequency with 1000+ items
  - Benchmark memory usage patterns

- [ ] Analyze Re-rendering Overhead
  - Trace unnecessary subtree updates
  - Identify expensive View comparisons
  - Document worst-case scenarios

#### Week 2: Caching & Memoization
- [ ] Improve Render Cache Strategy
  - Implement more aggressive line-diffing
  - Add cell-level caching for Lists/Tables
  - Cache computed layout measurements

- [ ] Optimize View Equality Checks
  - Fast-path for identical views
  - Reduce struct comparison overhead
  - Profile @State change propagation

#### Week 3: List/Table Virtualization
- [ ] Implement Virtual Scrolling for List
  - Only render visible items + buffer
  - Lazy-load item content
  - Benchmark with 10,000+ items

- [ ] Optimize Table Rendering
  - Column-by-column render optimization
  - Cache column widths across renders
  - Reduce table redraw frequency

#### Week 4: Testing & Validation
- [ ] Performance Benchmarks
  - Create benchmark suite (large lists, many components, rapid updates)
  - Set performance targets (e.g., <16ms render time for 1000 items)
  - CI integration for regression detection

- [ ] Load Tests
  - Stress test with complex UI hierarchies
  - Validate memory stability over time
  - Real-world scenario testing

### Deliverables
- ✓ Performance benchmarks suite
- ✓ 50%+ speedup on large list rendering
- ✓ Render cache improvements documented
- ✓ No regressions in existing tests

## Phase 2: TextInput / TextField Component (March 2026) – 3 Weeks

**Goal:** Developers can collect user input with a production-ready TextInput component.

### Milestones

#### Week 1: Design & Architecture
- [ ] Define TextInput API
  - SwiftUI-compatible modifiers (`.placeholder()`, `.disabled()`, `.keyboardType()`)
  - Validation support
  - Focus behavior

- [ ] Architecture Design
  - Cursor position management
  - Edit state tracking
  - Keyboard event handling

#### Week 2: Implementation
- [ ] TextInput Component
  - Basic text editing (insert, delete, backspace)
  - Cursor navigation (arrow keys, Home, End)
  - Text selection (Shift+arrows, Ctrl+A)
  - Paste/Copy support

- [ ] Modifiers & Validation
  - `.placeholder()`, `.disabled()`, `.onChange()`
  - Input validators (min/max length, regex patterns)
  - Error state display

#### Week 3: Testing & Polish
- [ ] Comprehensive Test Suite
  - Keyboard input scenarios
  - Edge cases (empty string, max length, special chars)
  - Integration with Forms

- [ ] Documentation & Examples
  - TextInput usage guide
  - Form pattern example
  - Validation patterns

### Deliverables
- ✓ TextInput component (stable API)
- ✓ 100+ test cases
- ✓ Documentation with examples
- ✓ Example form app

---

## Phase 3: Documentation & SDK Polish (April 2026) – 3 Weeks

**Goal:** TUIkit is discoverable, learnable, and production-grade.

### Milestones

#### Week 1: Documentation Expansion
- [ ] Component Gallery
  - Interactive examples for every component
  - Copy-paste ready code snippets
  - API reference generation (DocC)

- [ ] Developer Guides
  - "Getting Started" tutorial
  - "Building Your First App" (step-by-step)
  - Common patterns (forms, lists, modals)
  - State management best practices

#### Week 2: Example Applications
- [ ] 3+ Real-World Examples
  - TODO App (CLI-style)
  - System Monitor (data visualization)
  - Form-Based Config Tool (TextInput showcase)

- [ ] Template Refinement
  - Update project-template with best practices
  - Add example code structure
  - Document template extensions

#### Week 3: Community & Release
- [ ] API Stability Review
  - Mark all public APIs stable (post 1.0)
  - Document breaking change policy
  - Version bump (1.0.0)

- [ ] Launch Preparation
  - Blog post: "TUIkit 1.0 – Production Ready"
  - Example gallery on landing page
  - GitHub release with migration guide

### Deliverables
- ✓ Complete API documentation
- ✓ 3+ example applications
- ✓ Developer onboarding guides
- ✓ TUIkit 1.0.0 release

---

## Cross-Cutting Work (Ongoing)

### Code Quality
- [ ] Maintain 100% test pass rate
- [ ] Keep SwiftLint warnings at 0
- [ ] Regular dependency updates

### Community
- [ ] GitHub Issues triage (weekly)
- [ ] Respond to discussions
- [ ] Collect feedback on TextInput design

### Architecture
- [ ] Swift 6 compliance (if new warnings emerge)
- [ ] SwiftUI API parity tracking
- [ ] Refactoring backlog management

---

## Success Metrics

**By End of Q1:**

- **Performance:** List rendering with 1000+ items at 60fps, <16ms per frame
- **Features:** TextInput fully functional, 100+ test cases
- **Documentation:** Developer can build app without Slack asking questions
- **Adoption:** TUIkit 1.0 release, public example apps, clear roadmap for Q2

---

## Open Questions / Decisions Needed

1. **Virtual Scrolling Trade-offs**
   - Should we prioritize viewport matching (Vim-style) or smooth scrolling?

2. **TextInput Scope**
   - Multi-line support in Q1, or defer to Q2?

3. **Example Apps Priority**
   - Which use case is most important to showcase first?

---

## Q2 Preview (May-July 2026)

- [ ] Advanced Form Components (DatePicker, Dropdown with async)
- [ ] Clipboard integration improvements
- [ ] Plugin/Extension system for custom components
- [ ] macOS/Linux-specific optimizations

---

## Resources Needed

- **Developer:** You (primary implementation)
- **AI Assistant:** Code generation, testing, documentation
- **Testing:** CI/CD already in place, expand benchmark suite

---

## Notes

- This roadmap is flexible – performance findings may shift priorities
- Community feedback on Phase 1 may inform Phase 2/3
- CI/CD can auto-validate performance benchmarks
