A made-up three-candidate Condorcet contest, one row per ballot: evidence account
In plain words
The count under instant runoff elected Ames because in round 1, 180 of the 300 ballots still counting counted for Ames, more than half.
No audit ran.
No container custody was supplied.
Outcome status: preliminary. Software tallies stay preliminary until an audit on the record confirms them or a full hand count of the record replaces them.
The contest
Title: A made-up three-candidate Condorcet contest, one row per ballot
Candidates: Ames, Baird, Cortez.
Records in this count: 300.
Ballot file: condorcet-cvrs
Source: Synthetic committed CVRs for the Ranked Robin comparison-form assertion audit. Invented for this package. No real election.
180 ballots rank Ames then Baird then Cortez, 60 rank Baird then Ames then Cortez, 60 rank Cortez then Ames then Baird. Ames wins both matchups 240 to 60, so Ranked Robin elects Ames without a tiebreak. Paper rankings are omitted, so they match the committed CVRs. This is a fixture, not a sealed container.
The grouped Alaska 2022 profile is not this file. Comparison-form needs 1:1 CVRs.
Where the records sat:
One stack of 300 records. There is no ballot manifest of sealed containers.
No container custody was supplied.

Election: A made-up three-candidate contest, counted under instant runoff
A demonstration configuration over committed fixture records, counting the same ballots under another rule. No audit ran under it, and no real election was counted under it.
Contests and candidates:
A made-up three-candidate contest (condorcet-cvrs): Ames; Baird; Cortez.
Counting rule: instant runoff.
Tiebreak: not used under this counting rule.
Ballot rules (how marks become a ranking):
Two or more marks at one rank: the ballot counts up to that rank and no further.
A candidate marked again lower down: that rank counts as a rank left blank.
2 ranks in a row left blank: the ballot counts up to there and no further.
A mark for anyone not on the ballot: a mark, so the rank is not blank, but never a vote.
Audit risk limit: 10%. A risk-limiting audit that runs under this configuration stops when the sample confirms the outcome at that limit, or sends the contest to a full hand count.
How a ballot is counted and how an audit stops are fixed by this version. Changing any of the lines above requires a new version id.
