Jack Grigg 0abc0ef11a book: Revert to the previous nullifier design 
We examined the nullifier designs more closely, and determined that the
previously-selected design was actually fine, but for a somewhat-subtle
reason: even though an adversary with knowledge of a victim's full viewing
key could choose psi to cancel out Hash_nk(rho), the nullifier still
directly depends on rho via the note commitment.

Jack Grigg 9410d14d0a book: Switch to a new nullifier design 
The previously-selected design was broken because an adversary with
knowledge of a victim's full viewing key could perform a Faerie Gold
attack: given knowledge of nk, they can choose psi to cancel out
Hash_nk(rho) and cause a collision.

Jack Grigg 0fcacf9af0 book: Start adding Orchard design notes 
Some of this content may move into the concepts section, or possibly into
a dedicated specification area, but for now the design section includes
our choices alongside the reasoning.
