The git-worktree fan-out tool for running Claude Code, Codex and Gemini in parallel shipped v3.42.0 with a breaking safety change: a plugin or wire client that asked wmux to drive a browser page without declaring its workspace used to get whichever page registered first, possibly one in an unrelated workspace, and now gets a non-retryable refusal. GitHub The bundled MCP server, CLI and app UI already send workspace. "mcp": {"mode": "shadow"} restores old behavior if you need it.
