Diathesis Alternation Bridge @cite{levin-1993} #
Connects empirical alternation data to the
LevinClass.participatesIn prediction function and Fragment verb entries.
Agreement #
All 40 data points agree with the LevinClass.participatesIn prediction
function. The CI rule correctly blocks cut via !instrumentSpec
(Levin p. 9–10: instrument specification requires an agent, blocking
the agentless inchoative).
Each theorem connects a datum's result to the output of
LevinClass.participatesIn. Changing either the data or
the prediction breaks exactly one theorem.
