In California, precinct (plus party in primary elections) uniquely
determines ballot style (set of contests). (Multiple precincts may use
the same ballot style.) While some polling places may serve multiple
precincts, each voter's ballot is determined by their precinct.

You will want to record on the printed ballot, in both human- and
machine-readable fashion, the precinct ID (and party in primary
elections). Since precinct IDs are assigned by county, you may also
want to add county information, but it is highly unlikely that ballots
from different counties will be mixed. (I note that county information
will probably be on the ballot in human readable form, as will the date
of the election.)

128 bits is probably overkill. Ballots will definitely be kept
segregated by county, and will certainly be segregated by election (the
ballots from one election safely locked up before the next election
begins).

I note that you are rediscovering the same issues that exist today with
optical scan and (recently decertified) punch card technology. I know
that Doug Jones is well-versed in election administration issues; you
might also enlist some VVPAT-friendly election officials to advise
you. (Yolo County Registrar Freddie Oakley has spoken out against
paperless DREs. San Mateo County Registrar Warren Slocum is another
possibility.)
