Update: Baseband firmware trace analysis confirms buffer overflow, not just array index issue.
Evidence from Jan 10 crash: - Explicit "!OVERFLOW!" marker in baseband trace (offset 0x00013365) - Watchdog reset: "rst wdog,6vdt_in_1" - Crash recovery: "gcb_crash_wakeup" - SDMState active at crash time Corrected flow: SDM transition → buffer overflow in baseband firmware → memory corruption → firmware deadlock → watchdog timeout → forced reboot Same trigger pattern on Jan 10, 11, 14.
