## 💡 Core Philosophy & Features

**Mini Diag Tool** is an advanced, driver-less hardware diagnostic tool built entirely from scratch in native C++ and Qt to handle Qualcomm chipsets without relying on heavy external wrappers (`QPST.dll`, `QMSL`, or third-party engines).

* **⚡ 100% Standalone:** Zero external DLL dependencies. Talks directly to COM serial ports.
* **🔌 Native HDLC & CRC-16 Engine:** Low-level implementation of HDLC framing (`0x7E`/`0x7D` escaping) and CRC-16 checksum verification for sub-millisecond response latency.
* **📶 Complete Dual-SIM (SIM 1 & SIM 2) Architecture:** Native SIM selection controls with mutual exclusion and independent identity/EFS parsing.
* **🔍 Silent SIM 2 Auto-Discovery:** Automatic background path discovery across 7 Qualcomm dual-SIM base paths (`/nv/item_files_1/`, `/policyman_1/`, etc.) with path masking.
* **⚙️ 3-Tier NV Fallback Engine:** Smart automatic fallback across Standard (`0x26`), Subsystem (`0x4B`), and Extended (`0x75`) DIAG commands, providing full compatibility with Snapdragon 8 Gen 1/2/3 chipsets.
* **🛡️ Watchdog-Protected Range Backup:** Unstoppable NV range backup with a dedicated 250ms watchdog timer (`m_backupWatchdog`) and 100ms item deadline to skip unpopulated NV IDs instantly.
