Reading arXiv:2609.29429 RLCDAlignBench: TypeSafe Jev (RLCD) on 10 alignment failures × 44 benchmarks hits median AUROC 0.886 with a generic question, ~63× cheaper than LLM judges; checklist for wiring Just-Ask-Jev into an agent harness monitor.

A deep read of Accenture arXiv:2609.28919—enterprise coding-agent bills are often blamed on “expensive models,” but the paper moves the blame to harness defaults; cache-safe routing with Jev recovers about 14–21% of model spend in a 10k-seat emulation, with a sovereignty ladder from observe to own.

A deep read of arXiv:2609.29769—typed classifier Jev vs three flash LLM judges on nine panels and 5,003 pairs: accuracy seldom separates, cost/latency gaps hit 29–325× and 30–220×, and correlated errors cap a cheap-first cascade at about +1.5pp.

A deep read of arXiv:2609.30243 JevOut—answer-preserving short context can redirect Jev and peer decision models from a correct choice to a pre-fixed wrong target—with checked numbers (Jev TFR 61.4%, high-confidence flips, BFCL tool-routing fragility) and a hardening checklist before treating probabilities as a control plane.
Read →A deep read of arXiv:2609.23986 Jev-Mem—separating memory organize/retrieve/stop into a System-One control plane—contrasted with this site’s Jev decision line and Growing Harness “sink control into code,” with checked LoCoMo numbers and a reusable design checklist.
Read →A deep read of arXiv:2609.30186 Jev-Mobile—moving Jev from judge/memory into an Android GUI executor—with checked AndroidWorld numbers (79% success; −32.7% time and −73.4% API cost on successful trajectories vs step-wise VLM) and a reusable VLM×typed-executor checklist.
Read →arXiv:2609.27678 compares Jev and nine hosted/local models on ContractNLI: cost, latency, baseline accuracy, and All-12 persistent correctness rank differently. Close means can hide flips—select on persistent correctness, not accuracy alone.
Read →A viral YouTube clip ties Jev to Claude Code, but Jev cannot be the CLI chat model. This post covers the official skill, boundary hooks, MCP, and per-turn routing, contrasts NobodyWho’s 25-line minimal build, and discusses OpenAI fast-follow pressure.
