Reads the three Law sockets and the worn World Law into one value.

A stone is dropped here, once, when it cannot do anything: its template is gone from the catalog, it ships active: false, or its rule needs a chosen law and the player has not chosen one. That last case is the whole of “a stone with no target does nothing” — no rule site repeats the check.
