Automated README summary
Automatically summarized from the README on 29 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A browser demo of a small robot walking down a road, driven by wiring from the real MaleCNS v1.0 fruit fly connectome. It is for anyone interested in connectome-based control and TypeSafe's Jev model.
How it uses Jev
Jev receives the robot's senses, mushroom-body valence, visual pathway drive and descending drive, then answers one choice question among six actions (walk_forward, veer_left, veer_right, walk_backward, takeoff, feed). The returned action is applied in js/jev.js; when stalled over 1.5 s, the action is sampled from Jev's probabilities.
Primitives:choice
Technique worth stealing
Use Jev's choice probabilities as a stochastic policy when the robot is stuck, instead of always taking the top action.
Try it
Set TYPESAFE_API_KEY in .env, run python3 arena/server.py, open http://127.0.0.1:8777 and press Play.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
