 ClawWatch bundles [NullClaw](https://github.com/nullclaw/nullclaw) `v2026.3.7` as a static ARM binary, paired with offline speech recognition (Vosk) and the built-in TTS engine. The current live response path uses Kotlin-side Anthropic calls, while the bundled NullClaw runtime remains in place for local agent state and the native watch runtime path.
