One-off tasks
Not everything repeats. One-off tasks are for things you do exactly once — renew the passport, register the car, replace a single broken blind. Pick Just once on the task form and choose a due date (it defaults to today, so a quick "remind me to do this" needs only a name).
A one-off behaves like any other task until it's done — it appears on the to-do list, the upcoming-tasks calendar, and the overdue/next-due sensors, and you can log the usual completion details (note, cost, who, photo). The difference is what happens after: instead of rescheduling, it goes dormant and drops out of every active surface, landing in a collapsed Completed section in the panel that keeps its completion record. Undoing the completion brings it right back to its due date.


Tidy up automatically. If you'd rather not let finished one-offs pile up, set
One-off retention (days) in the panel's Settings tab (or via the
home_keeper.set_options service): a completed one-off is deleted that many days
after it's done. The default — 0 — keeps them forever.
