Why haunting is the interesting one
Haunting needs Soul Fire beneath a moving item rather than a machine, which makes it the cheapest automation in the whole addon to build and the easiest to overlook. A belt, a soul campfire and a chest is the entire setup, and it runs continuously without power once the belt is turning.
That matters because haunting is how this addon makes several of its rare outputs renewable. An item that previously required a structure or a mob drop becomes something a belt produces while you are elsewhere.
Compacting the expensive things
Compacting covers the other half of the rare-item list, and it behaves differently: it wants a basin under a Mechanical Press, and it consumes the exact ingredients each time. Because rare inputs are by definition in short supply, build the compacting station with a filtered input rather than a raw belt feed, so a mis-delivered stack cannot be pressed into something you did not want.
Running both unattended
The two processes pair well. Haunting is slow, continuous and cheap; compacting is fast, batched and expensive. Feeding a haunting belt from a bulk storage and letting its output accumulate into the compacting basin gives you a line that converts common material into rare material overnight, with no player interaction beyond restocking the input.
Keep an overflow on the haunting output. A soul-fire belt does not stop when the destination chest fills, and items that back up onto the belt will simply be re-processed or lost.
