This object reports the kernel version stored in boot bank 1 of the module, the counterpart to bank 0 in the device's dual-bank boot design. Because bank 1 typically holds a different kernel build than bank 0 (often the previous release, kept intact as insurance), this field is what an admin checks to confirm exactly which version would boot if the device ever had to fall back to this specific bank. For example, bank 1 might report an older kernel version that predates the one currently running from bank 0, confirming a genuine fallback option exists.
