Do cards spent to build go under the new building or onto the discard pile?
The rulebook's Builder section has you pay by discarding cards; the list of cases where cards stay stacked comes from a forum post.

They go face down to the discard pile. Per a forum post, cards sit on top of other cards only in specific cases: goods on production buildings, cards under a Chapel, and a building covered by a Crane.
