 ### Fixed
 
 - Fixed `omp update` leaking Bun's raw `fetch()` error ("pass `verbose: true` in the second argument to fetch()") when a proxy environment variable (`HTTPS_PROXY`, `ALL_PROXY`, …) uses an unsupported scheme such as SOCKS; the update check now reports an actionable message naming the offending variable and the http/https proxy requirement ([#8784](https://github.com/can1357/oh-my-pi/issues/8784)).
+- Fixed worker subprocesses (memory embeddings, tiny-model titles, TTS/STT, JS eval, browser relay, LSP mux, daemon broker) running with their cwd pinned to the CLI install directory. They share the agent's foreground process group, and terminal cwd heuristics such as kitty's `new_tab_with_cwd` pick the newest process in that group, so new terminal tabs opened in `~/.bun/install/global/node_modules/@oh-my-pi/pi-coding-agent/dist` while any worker was alive. Workers now spawn with the absolute host entry and inherit the agent's cwd.
