What it is
HEIST//ONE is a browser stealth game for players and developers: six guards, three access-controlled doors, disguises, credentials, light control, noise decoys, one artifact, and two exits, with an authoritative server simulation and a Decision Lens.
How it uses Jev
Jev supplies batched typed judgments for every guard: whether local evidence suggests a threat (Noul), how suspicious a guard should be (Score), which legal tactical intent fits (Choice), and which observed entity deserves attention (Choice). The server validates policy and freshness before any proposal affects the 30 Hz simulation.
Primitives:choicescorenoul
Technique worth stealing
Treat every provider response as a proposal; deterministic code validates legality, freshness, and policy before acting.
Try it
pnpm install --frozen-lockfile && pnpm dev; scripted mode is default, no API key needed.
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.
