Both of the things you're asking about are better regarded as myths or bombastic pipe dreams rather than as functional entities, for the simple reason that the mere mention (much less planning/execution) of either requires an assumption of Nazi defeat, which would have been regarded as defeatist and treasonous by Hitler, and thus punishable by death.

Some fringe historians will naturally latch onto them because of their sinister or romantic nature, however you'd be very hard-pressed to prove that either endeavor produced much of note (with the possible exception of the Allies believing that the Redoubt existed, which ironically did have some minor impact). Both concepts also had some value for Allied propaganda purposes, which further contributed to muddy the waters in terms of determining their existence/impact. In reality most cases of supposed "Werwolf" insurgencies are more easily and simply explained as the spontaneous actions of die-hard individuals or small groups, rather than intentional actions resulting from an officially endorsed plan.
