Control UI “device signature invalid” — token field mismatch between client signing and server
증상
Regression (worked before, now fails)
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
A Tampermonkey userscript that injects #token=<shared-token> into the URL on every page load (@run-at document-start), before the app’s <script type="module"> executes. The app reads the token from the URL hash in applySettingsFromUrl(), re-establishing the connection on each refresh.
