What a transaction publishes

A Zcash transaction publishes its version, the pools it touches, its per-pool value balance, its nullifiers, its anchors, its commitments, and its transparent inputs and outputs. All of that is exact. The fee is not among them: a fee is the difference between the outputs a transaction spends and what it pays out, and the outputs it spends belong to earlier transactions, so it is computed here rather than read - and where an earlier output cannot be resolved, this page says so instead of naming a figure. What no transaction publishes is a sender inside the pool, and no amount of arithmetic on the rest produces one - so what follows the public fields is a candidate set, its filters, and the assumptions each filter rests on.
