https://www.ietf.org/id/draft-autocrypt-lamps-protected-headers-02.html Makes it clear that the "Legacy Display" part of an encrypted message with protected headers can (and indeed, should) be of content-type text/plain, though some clients still generate the Legacy Display part as content-type text/rfc822-headers. Notmuch should recognize the part whichever of the two content-types it uses. See also discussion in https://github.com/autocrypt/protected-headers/issues/23 for why the community of implementers is moving in the direction of text/plain.
