A Tuesday morning. One sibling stops by before work and sees the 8:00 slot is full. A home aide arrives at 9:30, sees the same full slot, and both mean to give it. Neither knows the other was there.
Poison Control names this exact setup, more than one person giving medicine without communicating, as a cause of double dosing. Its fix is plain: decide who gives each dose, and keep a log next to the medicine. That's the idea we built DoseBeacon around.
