Find the way a player can lose the item a quest still needs

The key is given once, the shop buys everything, and ten minutes later the door cannot be opened any more. Here is the search over everything a player can do with their pockets that finds the first moment the quest becomes impossible.

Why this works

A quest breaks when the player reaches a situation from which no road leads to the goal, and that situation may sit several steps away from any single item. Looking at every possible situation, and asking which ones can still win, finds what checking items one by one cannot.

When not to use it

Skip it when the quest is a short straight line with nothing to sell, drop or lose; a quick play-through is enough there. It also gets slow when the player can hold many different things, so split the world into small parts and check each part alone.
