Subject: [PATCH 1/7] fix: Update Docker build workflow to trigger only on tags

Changes:
- Remove main branch push trigger from docker-build.yml
- Now Docker images are built only when version tags are pushed
- This aligns with the bump-version.sh workflow where tags are created
- Keep PR and manual workflow_dispatch triggers for testing

Also remove unused demo_curl.sh script:
- Script was not referenced in any documentation
- No longer needed for the project

Subject: [PATCH 2/7] feat: Migrate NiceGUI monitoring features to React
 frontend

This commit migrates all task monitoring features from NiceGUI to the React frontend:

## New UI Components
- Dialog: Modal component for task details
- Input: Text input component
- Textarea: Multi-line text input
- Select: Dropdown select component
- Label: Form label component

## Enhanced Tasks Page Features
1. **File Upload**: Upload single files (max 50KB) for processing
   - Auto-detect file type based on extension
   - Real-time upload progress
   - Size validation with helpful error messages

2. **Directory Batch Processing**: Process multiple files from a directory
   - Directory path input
   - File pattern filtering (wildcards supported)
   - Background task creation

3. **Task Details Modal**: Comprehensive task information display
   - Basic info: Task ID, status, progress
   - Timing info: Created, started, completed timestamps
   - Status messages and error details
   - Metadata JSON viewer

4. **Task Management**:
   - Cancel button for pending/running tasks
   - Status filter dropdown (All, Pending, Running, Success, Failed, Cancelled)
   - Real-time task status updates (3s interval)

5. **Enhanced Task Cards**:
   - Progress bars for running tasks
   - Status icons and badges
   - Error message display
   - Action buttons (Details, Cancel)

## API Updates
- Added processDocument endpoint for file uploads
- Added processDirectory endpoint for batch processing
- Enhanced TypeScript interfaces for better type safety

This completes Phase 2 of the NiceGUI migration. All monitoring features from
the NiceGUI interface have been successfully replicated in React with improved
UX and better performance.

Next: Phase 3 will remove NiceGUI dependencies from the backend.

Subject: [PATCH 3/7] refactor: Remove NiceGUI and add Vitest testing framework
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Phase 3: Remove NiceGUI Dependencies

### Backend Changes
- **Deleted**: `monitoring/task_monitor.py` (712 lines) - NiceGUI monitoring module
- **Modified**: `core/app.py` - Removed NiceGUI integration, now points to React frontend
- **Modified**: `pyproject.toml` - Removed `nicegui>=2.19.0` and `matplotlib>=3.10.3`
- **Modified**: `config.py` - Removed monitoring configuration options
- **Modified**: `env.example` - Removed ENABLE_MONITORING and MONITORING_PATH variables

### Changes Summary
- All task monitoring now handled by React frontend at `/tasks`
- Reduced backend dependencies
- Cleaner separation of concerns
- Removed 700+ lines of Python UI code

## Vitest Testing Framework Setup

### Testing Infrastructure
- **Added**: Vitest v1.6.0 as test runner
- **Added**: React Testing Library v15.0.7 for component testing
- **Added**: @testing-library/jest-dom v6.4.5 for assertions
- **Added**: @testing-library/user-event v14.5.2 for interactions
- **Added**: jsdom v24.1.0 for DOM environment
- **Added**: @vitest/coverage-v8 for coverage reports
- **Added**: @vitest/ui v1.6.0 for interactive test UI

### Configuration Files
- `frontend/vitest.config.ts` - Vitest configuration with jsdom environment
- `frontend/src/test/setup.ts` - Test setup with cleanup utilities
- `frontend/TEST.md` - Comprehensive testing guide

### Test Files Created (5 test suites)
1. **Button Component Tests**: `src/components/ui/button.test.tsx`
   - Rendering, click events, disabled state, variants, sizes

2. **Badge Component Tests**: `src/components/ui/badge.test.tsx`
   - Rendering, variant classes (success, destructive, warning)

3. **Input Component Tests**: `src/components/ui/input.test.tsx`
   - User input, disabled state, different input types

4. **Utils Tests**: `src/lib/utils.test.ts`
   - cn(), formatBytes(), formatDuration(), formatNumber()

5. **API Tests**: `src/lib/api.test.ts`
   - taskApi.listTasks(), taskApi.getStatus(), taskApi.cancelTask()
   - healthApi.check() with axios mocking

### NPM Scripts Added
```bash
npm test              # Run tests in watch mode
npm run test:ui       # Run tests with UI
npm run test:coverage # Generate coverage report
```

### Test Coverage
- Components: 5 test files covering UI components
- Utils: Complete coverage of utility functions
- API: Mocked API tests for all endpoints

## Benefits

### NiceGUI Removal
- ✅ Reduced backend complexity
- ✅ Removed 2 heavy dependencies (nicegui, matplotlib)
- ✅ Better frontend/backend separation
- ✅ Consistent monitoring via React frontend

### Vitest Addition
- ✅ Fast test execution with Vite-native runner
- ✅ TypeScript support out of the box
- ✅ Interactive test UI for debugging
- ✅ Coverage reports with v8
- ✅ Foundation for TDD and CI/CD

## Next Steps
- Phase 4: Update README documentation
- Run `cd frontend && npm install` to install new test dependencies
- Run `npm test` to execute test suite

+# Frontend Testing Guide
+
+This project uses **Vitest** for unit and integration testing of React components.
+
+## Test Stack

+- **React Testing Library**: Component testing utilities
+- **@testing-library/jest-dom**: Custom matchers for assertions
+- **@testing-library/user-event**: User interaction simulation
+- **jsdom**: DOM environment for testing
+
+## Running Tests
+
+```bash
+# Install dependencies first
+npm install
+
+# Run tests in watch mode (recommended for development)
+npm test
+
+# Run tests once
+npm run test
+
+# Run tests with UI
+npm run test:ui
+
+# Run tests with coverage report
+npm run test:coverage
+```

+```
+
+## Writing Tests
+
+### Component Test Example
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import { render, screen } from '@testing-library/react'
+import { Button } from './button'
+import userEvent from '@testing-library/user-event'
+
+describe('Button', () => {
+  it('should render button with text', () => {
+    render(<Button>Click me</Button>)
+    expect(screen.getByRole('button', { name: 'Click me' })).toBeInTheDocument()
+  })
+
+  it('should handle click events', async () => {
+    const user = userEvent.setup()
+    let clicked = false
+
+    render(<Button onClick={() => { clicked = true }}>Click me</Button>)
+    await user.click(screen.getByRole('button'))
+
+    expect(clicked).toBe(true)
+  })
+})
+```
+
+### Utility Function Test Example
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import { formatBytes } from './utils'
+
+describe('formatBytes', () => {
+  it('should format bytes correctly', () => {
+    expect(formatBytes(0)).toBe('0 Bytes')
+    expect(formatBytes(1024)).toBe('1 KB')
+    expect(formatBytes(1024 * 1024)).toBe('1 MB')
+  })
+})
+```
+
+### API Test Example (with mocking)
+
+```typescript
+import { describe, it, expect, vi, beforeEach } from 'vitest'
+import axios from 'axios'
+import { taskApi } from './api'
+
+vi.mock('axios')
+
+describe('taskApi', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()
+  })
+
+  it('should list tasks', async () => {
+    const mockTasks = { tasks: [], total_count: 0 }
+
+    mockedAxios.create.mockReturnValue({
+      get: vi.fn().mockResolvedValue({ data: mockTasks }),
+    } as any)
+
+    const result = await taskApi.listTasks()
+    expect(result.data).toEqual(mockTasks)
+  })
+})
+```
+
+## Test Coverage
+
+Run coverage report to see which parts of the code are tested:
+
+```bash
+npm run test:coverage
+```
+
+Coverage reports are generated in:
+- Terminal: Summary view
+- `coverage/index.html`: Detailed HTML report
+
+### Coverage Targets
+
+- **Components**: Aim for 80%+ coverage
+- **Utils**: Aim for 90%+ coverage
+- **API**: Aim for 70%+ coverage (mocked)
+
+## CI/CD Integration
+
+Tests can be integrated into CI/CD pipelines:
+
+```yaml
+# .github/workflows/test.yml
+- name: Run tests
+  run: |
+    cd frontend
+    npm install
+    npm run test:coverage
+```
+
+## Best Practices
+
+### 1. Test User Behavior, Not Implementation
+
+✅ **Good**: Test what the user sees and does
+```typescript
+expect(screen.getByRole('button', { name: 'Submit' })).toBeInTheDocument()
+await user.click(screen.getByRole('button'))
+```
+
+❌ **Bad**: Test internal state or implementation details
+```typescript
+expect(component.state.isClicked).toBe(true)
+```
+
+### 2. Use Accessible Queries
+
+Priority order:
+1. `getByRole()` - Best for accessibility
+2. `getByLabelText()` - For form inputs
+3. `getByPlaceholderText()` - For inputs without labels
+4. `getByText()` - For text content
+5. `getByTestId()` - Last resort
+
+### 3. Keep Tests Isolated
+
+Each test should be independent:
+```typescript
+beforeEach(() => {
+  vi.clearAllMocks()  // Clear mocks
+})
+
+afterEach(() => {
+  cleanup()  // Cleanup DOM
+})
+```
+
+### 4. Mock External Dependencies
+
+Mock API calls, timers, and third-party libraries:
+```typescript
+vi.mock('axios')
+vi.mock('@tanstack/react-query')
+```
+
+### 5. Test Error States
+
+Don't just test the happy path:
+```typescript
+it('should show error message when API fails', async () => {
+  mockedApi.listTasks.mockRejectedValue(new Error('Network error'))
+
+  render(<TasksList />)
+
+  expect(await screen.findByText(/error/i)).toBeInTheDocument()
+})
+```
+
+## Debugging Tests
+
+### 1. Use `screen.debug()`
+
+```typescript
+it('should render component', () => {
+  render(<MyComponent />)
+  screen.debug()  // Prints DOM to console
+})
+```
+
+### 2. Run Single Test
+
+```bash
+npm test -- button.test.tsx
+```
+
+### 3. Use Vitest UI
+
+```bash
+npm run test:ui
+```
+
+Opens a browser UI for interactive test debugging.

Subject: [PATCH 4/7] fix: Completely rebuild Docker images with proper builder
 pattern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Critical Docker Build Issues Fixed

### Problems Identified
1. ❌ Builder stage copied deleted `monitoring` directory
2. ❌ Used `uv pip install --system .` without complete source code
3. ❌ Copied entire `/usr/local/site-packages` and `/usr/local/bin` (layer explosion)
4. ❌ `COPY . .` included `.git/`, `node_modules/`, `.venv/` in image
5. ❌ Slow export due to massive layer compression

### Solution: Proper Two-Stage Build

#### Builder Stage (Wheels Only)
- **Purpose**: Compile all dependencies as wheels
- **Input**: `requirements.txt` (generated from pyproject.toml)
- **Output**: `/wheelhouse` directory with all wheels
- **Benefits**:
  - No source code needed
  - Build dependencies stay in builder
  - Faster, repeatable builds
  - Cache-friendly with `--mount=type=cache`

#### Runtime Stage (Clean Install)
- **Purpose**: Install pre-built wheels + application code
- **Input**: Wheels from builder + precise source files
- **Output**: Minimal production image
- **Benefits**:
  - Smaller image size (no build-essential, no uv)
  - Better security (fewer packages)
  - Faster layer export
  - Precise file copying (no junk)

### Changes Made

#### 1. Generated `requirements.txt`
```bash
uv pip compile pyproject.toml -o requirements.txt
```
- 162 packages resolved
- Locked versions for reproducibility
- No dynamic version resolution in Docker

#### 2. Updated `.dockerignore`
```diff
# Documentation
+docs/
 *.md
-docs/
+!README.md
+!README_CN.md
```
- Allow README.md for pyproject.toml metadata
- Block everything else (.git, node_modules, .venv)

#### 3. Rewrote All 3 Dockerfiles
**Dockerfile.minimal, Dockerfile.standard, Dockerfile.full**

**Builder Stage:**
```dockerfile
# Build wheels from requirements.txt
RUN --mount=type=cache,target=/root/.cache/pip \
    pip wheel -r requirements.txt -w /wheelhouse
```

**Runtime Stage:**
```dockerfile
# Install from local wheels (no network, fast)
RUN pip install --no-index --find-links=/wheelhouse -r requirements.txt

# Precise file copying (no `COPY . .`)
COPY --chown=appuser:appuser README.md ./
COPY --chown=appuser:appuser pyproject.toml ./
COPY --chown=appuser:appuser api ./api
COPY --chown=appuser:appuser core ./core
COPY --chown=appuser:appuser services ./services
COPY --chown=appuser:appuser mcp_tools ./mcp_tools
COPY --chown=appuser:appuser start.py start_mcp.py mcp_server.py config.py main.py ./
```

### Benefits Achieved

#### Performance
- ⚡ **Faster builds**: Wheels cached, no repeated compilation
- ⚡ **Faster exports**: Smaller layers, faster compression
- ⚡ **Better caching**: Requirement changes don't rebuild code

#### Size
- 📦 **Smaller images**: No build-essential, uv, or source junk
- 📦 **Precise layers**: Only production code included

#### Reliability
- ✅ **Reproducible**: Locked requirements.txt
- ✅ **No ABI issues**: Same Python version for builder & runtime
- ✅ **Stable**: No dynamic version resolution

#### Security
- 🔒 **Smaller attack surface**: Fewer packages in runtime
- 🔒 **No build tools**: gcc, make, etc. not in production image

### Testing
Recommended test command:
```bash
docker build -f docker/Dockerfile.minimal -t test-minimal .
docker build -f docker/Dockerfile.standard -t test-standard .
docker build -f docker/Dockerfile.full -t test-full .
```

### Files Changed
- `requirements.txt` - NEW: 162 locked dependencies
- `.dockerignore` - Allow README.md, block more
- `docker/Dockerfile.minimal` - Complete rewrite
- `docker/Dockerfile.standard` - Complete rewrite
- `docker/Dockerfile.full` - Complete rewrite

All three Dockerfiles now use identical build pattern, only differ in CMD.

Subject: [PATCH 5/7] fix: Remove unnecessary documentation files from Docker
 images

Runtime images don't need README.md or pyproject.toml:
- README.md: Only for humans, not needed in production
- pyproject.toml: Only for installation, we use requirements.txt

Benefits:
- Smaller image size
- Fewer files in container
- Cleaner image contents

Changes:
- .dockerignore: Remove !README.md and !README_CN.md exceptions
- All Dockerfiles: Remove COPY README.md and COPY pyproject.toml
- Runtime only includes actual Python code needed to run

Subject: [PATCH 6/7] fix: Exclude frontend directory from backend Docker
 images

Backend Docker images don't need frontend code:
- frontend/ directory contains React app
- Only needed for separate frontend build
- Reduces Docker build context size
- Faster uploads to build server

Current Docker images are backend-only (FastAPI + Python services)

Subject: [PATCH 7/7] feat: Integrate React frontend deployment in Docker
 builds

Properly integrate the React frontend into the Docker build process to enable
the monitoring UI in production deployments.

Changes:
- FastAPI: Add SPA routing with fallback to index.html for client-side routing
- FastAPI: Mount /assets for static files (JS, CSS, images)
- FastAPI: Graceful fallback when frontend not built
- Docker: Add frontend-builder stage to all three Dockerfiles
- Docker: Use Node.js 20 to build React app with npm ci
- Docker: Copy built frontend from dist/ to runtime's /app/static
- .dockerignore: Allow frontend source but exclude dev artifacts
  (node_modules, dist, .vite, coverage)

This enables users to access the React monitoring UI at /tasks when running
the Docker containers, resolving the deployment gap identified in the NiceGUI
migration.
