 - `./labctl update_wiki` hard-resets the managed wiki checkout to the remote latest, rebuilds it, and restarts only the managed wiki service on port `80`.
 - `./labctl start core` starts only `ollama` and `open-webui`.
 - `./labctl start all` starts every managed web service.
-- `./labctl open kiln` launches the Kiln desktop app installed into the project state.
 - The scripted Promptfoo install drops a starter config at `state/lab6/promptfoo.yaml`.
 - `labctl start all` includes Promptfoo via `promptfoo view` and the cloned wiki app.
 - Lab 2 includes `state/lab2/download_whiterabbitneo-gguf.sh`, which uses `git` + `git lfs` to pull only the supported WhiteRabbitNeo quants. Add `--download-only` if you want the files without Ollama registration.
