The mix-net now runs across separate parties over the signed transport: the server pads the ballot box and hands it to CC0; each CC shuffles + partially decrypts and passes the (validated) ciphertexts to the next; the electoral board performs the final shuffle + decryption. Ciphertext handoffs cross the authenticated transport; each party posts its shuffle and decryption proofs to the public transcript (the bulletin board). - tally.go: RunTally orchestration + per-party handlers (server pad, CC shuffle, EB final decrypt). Persists the padded mix input and per-stage partial decrypts to the transcript (fixes F7/F8 in the multi-party setting). - verify.go: RunVerify has the verifier independently re-check every CC Schnorr proof and the whole shuffle chain from the transcript alone (no secrets). - returncodes: DecodeVoteChecked returns an error instead of panicking on a non-smooth plaintext (fixes F12), used on the tally path so a corrupt ballot is counted as spoiled rather than crashing the tally. Tests: the full ceremony (setup -> cards -> voting -> tally -> verify) produces the correct tally over 124 verified transport messages; the verifier rejects a transcript with swapped Schnorr proofs.
