## Technical Details

### Helpwo Architecture
- Pure web application, all data stored in browser IndexedDB
- Built-in CodeMirror 6 editor with syntax highlighting
- AI chat via SSE streaming with OpenAI-compatible function calling
- Remote Agent protocol for CLI-to-Web communication

### Kline-de-pre AI Pipeline
1. Image Detection (OpenCV.js): Screenshot → HSV color space → green/red mask extraction → contour detection → OHLC reconstruction
2. Transformer Trend Extraction: GAF (Gramian Angular Field) encoding → 12-channel polar feature tensor → Transformer ONNX inference → DCT coefficients
3. Diffusion Synthesis: DDPM 1000-step reverse diffusion → UNet ONNX model → OHLC residuals → full K-line prediction

### Platform
- Auth: better-auth with MySQL, Google/GitHub OAuth, email OTP
- Billing: PayPal integration, atomic balance deduction with idempotency
- Inference: MCP protocol, proxy-based with balance pre-check
