Zaino Respecification

Too early to vote.

Zingo Labs: Unanticipated architectural challenges have emerged in the Zaino project due to inaccuracies in the published zcashd RPC specifications. To address this without delaying the overall Zaino timeline, we are reallocating additional development resources to rewrite key components of the architecture. This grant will support the effort to define, implement, and test a reliable and authoritative spec that aligns with the updated Zaino implementation. They are requesting $44,000. This grant was posted yesterday so the committee has not yet had time to review.
