   - Upgraded to **Ubuntu 24.04 LTS (Noble Numbat)** base with real-time `linux-image-lowlatency` (1000Hz timer, preemptible) as the default boot kernel.
   - Dual-kernel fallback architecture (`linux-image-generic` alongside low-latency kernel).
   - SCTP kernel tuning, unlimited `RLIMIT_MEMLOCK`, and `SCHED_RR` real-time scheduling for drop-free SDR streaming.

 - **Bundled Offensive Tools**: TelcoChisel deliberately ships security auditing tools (e.g., 5Ghoul, SigPloit, QCSuper, FirmWire, srsRAN, Open5GS) whose intended purpose is finding and demonstrating vulnerabilities in cellular protocols. Behavior that is part of a tool's normal offensive operation is not considered a TelcoChisel vulnerability.
