I don't really know how to interpret this but I've been getting consistent crashes once my battery hits around 25% charge and the widely reported "AP watchdog expired" error message. Battery capacity's now at 71% and dropping rapidly after sub 500 charge cycles. Couple months out of 1 year warranty. Any advice is appreciated, would hope I'm not just shit out of luck for such an expensive device after ~15 months.

You have a bad battery and need a new one. Should be fine afterwards.

2020 M1 Air running whatever the latest beta macOS is. Not too shabby all things considered... I mostly do light dev work and music production (primarily live instrumentation so not too much in the way of sample-based plugins) so this kind of makes sense.
