dsh-web-compat

Accessing the DeepSeek Harness Web UI over a plain HTTP LAN address (e.g. http://192.168.x.x:3080) puts the browser in a non-secure context, where crypto.randomUUID() is simply undefined. The official chat interface crashes the moment you try to attach an image, making the feature completely unusable.

The plugin takes a straightforward approach: since crypto.getRandomValues() remains available even in a non-secure context, it injects a UUID v4 polyfill built on getRandomValues at the top of the client bundle module, ensuring randomUUID works reliably in every network environment. It also registers a new Web Compat status panel in the Settings page, showing in real time whether the current context is secure and where randomUUID is actually sourced from, so you can quickly diagnose your environment.

If you routinely access dsh web via a LAN IP over HTTP, or frequently switch to non-localhost addresses during development and debugging, this plugin removes the browser security-policy friction and keeps the image attachment feature stable across all network configurations.
