What it is
A web app where players ask free-form Japanese questions to solve lateral thinking puzzles, and Jev answers yes/no/irrelevant and judges final answers.
How it uses Jev
Jev receives the puzzle statement, truth, and player's question, and returns a Choice among yes/no/irrelevant. For final answers, Jev receives the solution conditions and player's answer, and returns a Noul probability of correctness.
Primitives:choicenoul
Technique worth stealing
Use typed primitives (Choice, Noul) instead of text generation to avoid off-format replies and hint leakage.
Try it
terraform init && terraform apply, then open the site_url output.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
