Novum Xenium v0.1.2

Android companion and clearer workspace

• Install the signed Android APK from this release or NX Hub. Connect to your existing Novum server through the app's embedded Tailscale connection, including approved router subnet routes, without a phone-wide VPN.
• Follow work through compact task cards, clearer run status, grouped tool activity, and a workspace drawer for previews, files, browser activity, and subagents.
• Choose models through a searchable provider-grouped picker with full names and truthful availability. Improved spacing, button alignment, and mobile layout.

Android requires Android 8 or newer, a current System WebView, an existing Novum server, and Tailscale authorization. LAN access requires an approved subnet route and matching tailnet policy. Native uploads and direct server-file downloads are supported; browser-generated blob downloads are not yet supported.

Validation: Go bridge and Kotlin unit tests, Android lint, signed APK and 16 KiB alignment checks, Android 15 emulator connection startup/browser sign-in, and desktop/mobile workspace browser checks. Physical phone and user-router connectivity remain to be verified. See android/VALIDATION.md for the tested boundary.
