Everything runs locally, no cloud. Tauri-based, signed and notarized macOS binary.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception. (v0.4.3, tagged semver release)
• brew audit --cask --online voicebox is error-free.
• brew style --fix voicebox reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused.
• brew audit --cask --new voicebox worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask voicebox worked successfully.
• brew uninstall --cask voicebox worked successfully.

Claude wrote the initial cask file. Manual verification performed:

• SHA-256 hashes computed locally via shasum -a 256 on both DMGs downloaded fresh from the v0.4.3 release.
• Notarization confirmed twice: once by mounting each DMG and running spctl -a -t exec -vv Voicebox.app on the contained .app, and once on the brew-installed /Applications/Voicebox.app. Both return accepted, source=Notarized Developer ID.
• Install / uninstall verified end-to-end locally. brew install --cask placed the app at /Applications/Voicebox.app, brew list --cask listed it, and brew uninstall --cask voicebox cleanly removed it.
• zap paths verified against a real Voicebox install. Running find ~/Library -iname '*voicebox*' surfaced that the app writes to both sh.voicebox.app (primary bundle id) and voicebox (WKWebView + Tauri productName fallback) variants under Application Support, Caches, Preferences, and WebKit. Both variants are captured in the zap stanza.

The notarization error may be a CI-related issue, because it is only occurring macos-15. Local checks seem ok to me.
There's no way for us to add macos-15 specifically to the skiplist at the moment, so we may need to make a change in Homebrew/brew to allow for it.

CI is an issue on my end actually, exposed a bug users were reporting that I couldn't replicate until running through your CI, our .app bundle was being notarized but not the DMG. I've just published a 0.4.3 update that fixes this, updating the PR now and addressing that livecheck feedback.

Huh, macOS 15 is still failing. However, 0.4.3 is locally clean: xcrun stapler validate passes on both the DMG and the inner .app, and spctl -a -vvv -t install returns accepted, source=Notarized Developer ID.

Not sure whats up with the CI, let me know if there's anything else I can do.

Nice work here. Thanks for showing how simple this is.
