What it is
DGP is an open-source protocol by Numerous ApS for building decision-based AI agents. Applications expose evidence, typed decisions, and guarded actions; an agent assesses choices while application code retains control of permissions and effects.
How it uses Jev
Jev is the intended first assessor. The agent reads an immutable frame of evidence and offered decisions, then produces a typed assessment using Jev or another eligible assessor. The application checks state and authorization before committing, then returns a receipt and next frame.
Primitives:choicescorenoul
Technique worth stealing
Immutable evidence frames with typed assessments and application-guarded commits keep permissions and effects under application control.

Clone repo, run local mock demo with uv, open browser, paste token, connect.
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.
