I am not a "dev", but since BTRFS utilizes a COW (Copy On Write)
architecture, it doesn't keep a journal or history of transactions
that can be unwound.

With respect to un-deleting files on BTRFS, the btrfs-find-root/'btrfs
restore' combination are the most effective user-space tools I know
of.

It sounds like you've effectively tried this manually, but here's a
link to an btrfs undelete script that also makes use of
btrfs-find-root and 'btrfs restore':
