 This project benefited greatly from the work, testing and research of several community contributors — especially: @ZoeBattleSand, @0x189D7997, and @JakeBrxwn. Their reverse-engineering, testing, tooling and discussion (see https://github.com/0x7375646F/Linuwu-Sense/pull/65) made much of this possible.
