## 5. Detailed Project Catalog

### 5.1 Byakugan Scan
- **Portfolio URL**: https://www.aritro.cloud/projects/byakugan-scan
- **Official Website**: https://byakugan-scan.aritro.cloud
- **Support & Docs**: https://byakugan-scan.aritro.cloud/support
- **Source Code**: https://github.com/halcyon-past/byakugan-scan
- **Install via Homebrew**: `brew install --cask halcyon-past/tap/byakugan-scan`
- **Tech Stack**: Swift 6.0, AppKit, SwiftUI, Apple Vision Framework, Neural Engine, macOS 14+, Homebrew Cask
- **Overview**: Byakugan Scan is a native macOS menu bar utility for instant, in-memory screen OCR, QR code, and barcode recognition. Unlike conventional screenshot OCR tools that write temporary image files to `/tmp` and wake up macOS Spotlight (`mdwrite`) or `MADService` daemons, Byakugan Scan captures selected screen regions directly into `NSPasteboard` memory as a `CGImage` buffer and runs `VNRecognizeTextRequest` and `VNDetectBarcodesRequest` on the Apple Neural Engine in under 50ms—with zero temporary files, zero network calls, and zero external Swift package dependencies.
- **Key Features**:
  - Zero-Disk In-Memory Pipeline (`NSPasteboard` -> `CGImage` -> Neural Engine in <50ms).
  - 60/120Hz Custom AppKit Overlay (`SelectionOverlayController`) with theme accents (`Byakugan Violet`, `Tenseigan Cyan`, `Sharingan Crimson`, `Sage Emerald`, `Nine-Tails Amber`).
  - Multi-Language OCR across 13+ languages and barcode decoding (QR, MicroQR, EAN-8/13, UPC-E, Code 128/39/93, PDF417, Aztec, Data Matrix).
  - Frosted-glass Floating HUD pill with word/character counts and one-click `Open URL`, `Send Email`, and `Call` actions.
  - Deep-link automation via `byakugan://` URL scheme for Raycast, Alfred, and macOS Shortcuts, plus searchable local scan history.
