Labs

A sparse-checkout research workspace of independent lab write-ups, two of which cover Jev: one on API behaviour, input limits and multilingual evaluation, another on moderation and pre-execution command risk checks.

About this project

Small, independent projects for experiments, research, and investigations. Use a shallow, partial clone with sparse checkout to fetch only one lab and the shared tasks: Connecting N orchestrator apps over WebRTC: one brain drives workers on many bodies, every console shows the same state - flutter, dart, webrtc, flutter-webrtc, data-channel, codex, codex-app-server, claude, claude-agent-sdk, kiapi, multi-agent, orchestration, distributed, macos.

Quoted from the project's README. Read the full README.

Highlights

  • Clone one lab instead of the repo with a shallow, blob-filtered clone plus git sparse-checkout set for the shared tasks and a single lab directory.
  • The Jev evaluation lab covers API behaviour, input limits and multilingual evaluation, tagged typesafe, jev, tokenizer, long-context and multilingual.
  • The Jev safety lab covers moderation and pre-execution command risk checks, tagged typesafe, jev, moderation, safety, calibration and agent.
  • Shared mise tasks and a Makefile sit at the root alongside the labs, so each lab inherits the same task runner.

Watch out

This is a workspace of unrelated experiments rather than an installable tool, and the two Jev labs are two write-ups among dozens of others spanning Flutter and Impeller bug reproductions, MLX and quantization benchmarks, an MCP 1 to MCP 2 migration, and video model ports. The labs are partitioned into date-named directories with per-lab READMEs and shared tag pages, so the entry point is an index rather than a command you run. To read a single lab you are expected to use the shallow sparse-checkout flow rather than pulling the whole tree. The listing here is the repository index, so the substance of each lab body lives in its own README rather than at the root. Copy reviewed against the repository README on 2026-10-04, not from running it.

Most Jev accuracy problems are state problems. What belongs in a state, what is a pre-made judgment to leave out, and why naming the slice you ask about matters more than the wording.
