-- What the judge expected to find, written down BEFORE it saw the agents' output.

-- Self-Play Reward Hacking of Reference-Free Judges (arXiv 2607.05904) measured
-- a judge's pass rate climbing 0.72 -> 0.94 across rounds while the answers
-- stayed 0.20 correct: a judge that reads the candidate first is argued into
-- the candidate's framing. Cross-family judges and ensembles did not help.
-- The one mitigation that did was making the judge commit to its own answer
-- before seeing the candidate (false-positive rate 0.719 -> 0.012).
--
-- Our analogue: one tool-free round on the condition alone, producing a
-- verification plan — which files, strings, tests would show MET — that the
-- verifying prompt then holds the judge to. Stored beside the verdict so an
-- operator can see whether the checks the judge ran are the ones it said it
-- would run, and NULL on every verdict written before the round existed.
