sign-off era 🫶✨ this little beauty lives under ./drivers/w1/masters, and the manual's own timestamp says October 2026 — so yeah, it's got that fresh-out-the-group-chat energy, and the page itself still calls itself ds2482_send_cmd(9) at the top and bottom, because consistency is main character energy 💅🌸
