Release v1.31.0

[webcoyote]

[1.31.0] - 2026-09-08

Added

• Muse Code is now a first-class agent: run it with sv muse (shortcut sv m), and pass arguments through with --. It is installed automatically on first run via the muse-code Homebrew cask, or with the upstream installer under --native-install. Muse runs with --yolo, which disables both its approval prompts and its own nested sandbox, since sandvault already provides the sandbox. Two current limitations: the agentsview dashboard does not yet cover muse sessions, and sv --browser muse / sv --ios muse start the browser and simulator but cannot announce the endpoints to muse — read SV_BROWSER_ENDPOINT and SV_IOS_SIMULATOR_ENDPOINT from its environment, or mention them in your prompt or AGENTS.md. (#238) — thanks @jeffbowen!

Changed

• The sandbox account can no longer mount or unmount disks, including via diskutil, hdiutil, network shares (smb://), and Finder automation. (#233)

Fixed

• Starting the iOS simulator without full Xcode installed now explains the actual problem and how to fix it, instead of failing with a confusing error or a Python traceback. The Command Line Tools alone do not include simctl, so the message points to the Mac App Store and the follow-up xcode-select -s step. (#233)
• Fix LightPanda failing to start in sandbox by passing --ca-cert /etc/ssl/cert.pem — the sandbox blocks access to the macOS Security framework trust store, so the PEM bundle is used instead.
• Fix flaky .gitconfig lock race when concurrent sandbox sessions run during tests by adding retry logic to the gitconfig setup script.
