Field notes
The proposed sequence is reserve, run, settle, or refuse: the page says a reservation is held against every applicable budget, then unused value is released after the actual charge is known. Its embedded note contrasts that mechanism with limits that react to a bill after a delay, and describes loop and velocity breakers. These are the maintainers’ claims and simulations; the homepage does not establish production performance. A paused scope is described as requiring a named person to resume it.
