Routine is defined by repetition, not by importance
A task belongs in routine because it needs doing every time, not because it matters most. Amenities, waste, floors in circulation areas, touchpoints and kitchen surfaces qualify because ordinary use degrades them between every visit. The test is simple: if leaving it for a fortnight produces a visible or hygienic problem, it belongs in routine. If it does not, putting it there just dilutes the visit.
That is why some genuinely important tasks are not routine. A full internal glass detail is important, but doing it every attendance in a building with public traffic wastes effort that the entrance doors need more. Sorting on repetition rather than on priority produces a routine list that can actually be completed in the time available, which is the first condition of a scope being met. A routine list that fits the visit is also the only list a site can reasonably check.
