Except with 3 catches:
- It must invert the keys ("bit-reversal permutation")
- It must be a dependency-free, pure recursive function
- It must have type

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.
Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

| # Apple Silicon laptops with firmware > 13.0 have a native charge threshold that does not required any userspace daemon running. | |
| # This native limit works even when the laptop is sleeping or powered off therefore it is preferable to the userspace daemon. | |
| # Nonetheless, it only works with fixed thresholds (80% as upper limit and 70% as lower limit). | |
| # CHWA key is the one used to enable/disable the native limit. 01 = 80% limit, 00 = no limit | |
