Environment

• macOS 26.2 (25C56)
• Mac mini M4 (Mac16,10)
• Clawdbot App 2026.1.23 (build 7750)
• Gateway running as LaunchDaemon (not LaunchAgent)
• No microphone connected

Problem

The desktop app crashes in two scenarios:

1. TalkMode crash (on startup)

TalkModeRuntime.startRecognition() fails because there's no microphone available. The app calls AVAudioNode installTapOnBus which throws an exception.

Workaround: Disable VoiceWake via:

defaults write com.clawdbot.mac VoiceWakeEnabled -bool false
defaults write com.clawdbot.mac TalkModeEnabled -bool false

2. CodeTokenizer crash (after connecting to gateway)

After applying the VoiceWake workaround, the app connects to the gateway successfully but then crashes on NSBundle.module / CodeTokenizer.init() with _assertionFailure.

Stack trace:

_assertionFailure(_:_:file:line:flags:)
closure #1 in variable initialization expression of static NSBundle.module
one-time initialization function for module
CodeTokenizer.init()
HighlightedTextFragment.Model.tokenize(content:languageHint:)

Expected behavior

The app should:

1. Gracefully handle missing microphone instead of crashing
2. Not crash on CodeTokenizer initialization

Notes

• Gateway works correctly (Telegram + webchat are functional)
• The Mac mini is used as a headless server without audio input devices
