(thing permanently committed EVENT OBJECT) means that as a result of EVENT, OBJECT is subsequently put into a configuration and/or a form where it is serving some ongoing role. Things which are re-usable in their typical uses: a videocassette, a battery, a brick, an artist's canvas, a canvas tent. Non-reusable things: paint, glue, mortar. See also input incorporated into the end result, Recyclable Actors. Consider a brick in a wall in a building. It is `committed for future use' in the role of part-of-a-wall in the event of that building existing. While the building is standing, it can't be part-of-a-wall in another building, though it could serve other roles such as an artistic accent, or to anchor a coat-hook. After the building is torn down, that brick might still be intact, and could be used as part-of-a-wall in a future building. Notice that the brick isn't necessarily transformed by being part of a wall. However, so long as OBJECT serves the use to which it is `assigned' by EVENT, OBJECT is unavailable to be assigned the same role by another event of the same type, at least an event that would temporally intersect with this committed use of OBJECT. That is what is meant by it being `committed' for a particular future use. An object may be re-used in a similar event, ONLY IF the role to which it was assigned in EVENT either comes to its natural end or is given up (or thwarted), or in cases where EVENT is composed of discontinous pieces of time --- to illustrate that latter case, consider a tent that's used to shelter a certain group of workers on weekdays, but is used to shelter a different group in a different location on weekends.
