Engineered with a \"security-first\" mindset, PayNix features encrypted data storage, strict buffer-overflow protections, atomic financial transactions, and role-based access control.\n\n---\n\n## ✨ Key Features\n\n### 🔐 Security \u0026 Data Integrity\n* **Role-Based Access Control (RBAC):** Distinct administrative and employee interfaces.\n* **Brute-Force Lockout Gates:** Progressive time delays on failed login attempts.\n* **Safe Memory Management:** Custom `SafeString` implementation prevents buffer overflows and mitigates scanner-paste injection attacks.\n* **Binary File Protection:** All database files feature Magic Number validation (`PNIX`), strict schema versioning, and cryptographic checksums to prevent data tampering.\n* **Schema Desync Gate:** Graceful schema migration and automatic legacy data archiving.\n* **Graceful OS Intercepts:** Traps `SIGINT` and `SIGTERM` to safely flush buffers and lock vaults during unexpected shutdowns.\n\n### 💰 Financial \u0026 Billing Engine\n* **Integer Cent Math:** Eliminates floating-point inaccuracies for absolute financial safety.\n* **Atomic Transactions:** \"Reality Gate\" validates inventory stock *before* processing to prevent race conditions or negative stock.\n* **Live \"Blind Biller\" Terminal:** Real-time cart editing, stock viewing, and interactive quantity management.\n* **JSON Export:** Automatically exports all finalized transactions to a secure JSON format.\n* **Z-Reports:** Automated end-of-day gross revenue and audit report generation.\n\n### 📦 Inventory Management\n* Full CRUD operations for items (Add, Update, Soft-Delete).\n* Stock validation and automated deductions.\n\n## 🛠️ Prerequisites\n\nTo build and run PayNix, you will need:\n* **CMake:** Version 3.20 or higher.\n* **C++ Compiler:** C++20 compatible compiler (GCC, Clang, or MSVC).\n* **Threads:** OS-level threading support (pthreads/Windows threads).\n\n## 🚀 Build Instructions\n\nPayNix uses CMake for cross-platform compilation. Follow these steps to build from source:\n\n1. **Clone the repository:**\n```bash\n   git clone [https://github.com/yourusername/projectpaynix.git](https://github.com/yourusername/projectpaynix.git)\n   cd projectpaynix\n```\n\n---\n\n## 📂 Project Structure\n```\nprojectpaynix/\n├── CMakeLists.txt        # Build configuration\n├── security.md           # Vulnerability reporting \u0026 supported versions\n├── include/              # Header files\n│   ├── Core.hpp          # System constants, types, and logging\n│   ├── Data.hpp          # Secure binary repository patterns\n│   ├── Logic.hpp         # Business logic (Auth, Inventory, Billing)\n│   ├── Models.hpp        # Data structures and SafeStrings\n│   ├── Security.hpp      # Cryptography, hashing, and sanitization\n│   └── UI.hpp            # Terminal rendering and inputs\n└── src/                  # Implementation files\n    ├── Logic.cpp         \n    ├── UI.cpp            \n    └── main.cpp          # Application entry point \u0026 OS traps\n\n```\n\n---\n\n© 2026 [Zenith Open Source Projects](https://zenithopensourceprojects.vercel.app/).
