Description​

Independently-owned state backing the filter stack.

The logger holds this by shared_ptr; each FilterToken references it by weak_ptr. A token that outlives its logger therefore removes nothing instead of dereferencing a destroyed logger — no use-after-free. Only the top entry is consulted per message; entries are removed by id, so out-of-order token destruction is handled correctly even though nested decorators normally pop in LIFO order. Empty in the common case, in which logging behaves identically to before this mechanism existed.
