Proactive should mean dependable, not persistent.
A checklist for the things that continue
Some requests are not finished in one exchange: watch this flight, tell me when the parcel moves, check this every Friday, keep the morning brief outside quiet hours.
Heartbeat places those routines, watchers, active travel checks and fixed rhythms in one legible list. It is the answer to a simple question: what is SA‑NT doing when I am not talking to her?
The same control, everywhere
Every cancellable item uses the same underlying stop action as the conversational tools. Ending a watcher on the page is the same decision as texting SA‑NT to stop it; there is no second shadow list.
Brief rhythm, stand-up timing and quiet hours remain in Settings and are linked from the same view.
Designed for absence
A conventional automation screen rewards activity. Heartbeat is designed to make inactivity comprehensible too. If nothing changed, nothing needs to interrupt you. If the list is empty, that emptiness should feel complete rather than broken.
