Wallpaper Packs

Themed wallpaper bundles you can install into the Library tab in a single click.

How it works

The Configurator's Library tab has a 📦 Wallpaper packs section at the bottom. Open it and the bridge fetches a manifest from this docs site (library-packs.json) listing every available pack — name, description, image count, total download size, and a SHA-256 of the ZIP.

Click Load on a pack and the bridge:

1. Downloads the pack ZIP from the library-packs-v1 GitHub release.
2. SHA-256-verifies the downloaded bytes against the digest in the manifest. Mismatch → install aborts, ZIP deleted.
3. Walks every entry in the ZIP before extracting anything and refuses any non-image entry (.exe, .dll, .bat, .ps1, …). A pack can only ever drop image files (.webp, .png, .jpg, .gif, .bmp, .avif) on disk.
4. Extracts the images into %LOCALAPPDATA%\SignalRGBWallpaper\library\ and rebuilds the library catalogue. Tiles appear in your Library grid immediately.

All four steps run server-side in the bridge's executor pool — the Configurator stays responsive during the download.

Available packs

Currently 13 packs, each containing 9 – 17 1920×1080 wallpapers (plus 4K + thumbnail siblings). Total catalogue around 400 MB if you install everything; individual packs are ~9 – 52 MB.

Why is this different from v2.0.x?

v2.0.0 had an in-app pack downloader. v2.0.1 ripped it out because Windows Defender's ML heuristic flagged the urlopen + zipfile.extractall pattern on the (then-unsigned) bridge as Wacatac.B!ml. The combination unsigned bridge in user-writable %LOCALAPPDATA% + downloads binary content into its own neighbourhood triggered classifiers that look for the "loader → payload" pattern of real malware.

v2.3.0-beta reintroduces the in-app installer with the v2.2.x mitigations in place:

• Bridge moved to C:\Program Files (v2.2.1). Admin-only ACL, not a user-writable persistence location.
• User-triggered downloads only — opening the section and clicking Load on a specific pack. No background polling for the pack manifest, no auto-installation.
• Manifest hosted on GitHub Pages (this docs site) rather than raw.githubusercontent.com — Pages traffic looks like normal docs fetches to AV / firewall heuristics.
• Image-extension whitelist enforced before extraction. The bridge inspects every ZIP entry up front; any non-image extension aborts the install. The extracted footprint is provably "image data only", which is much harder to classify as loader-shaped.
• SHA-256 verification of every downloaded ZIP against the manifest digest.

If Defender still flags the download on your machine, the browse packs on GitHub fallback is one click away — same ZIPs, manual extract into %LOCALAPPDATA%\SignalRGBWallpaper\library\, same end result.

Licensing

Every pack carries its full generator + license chain in the manifest. Current packs were all produced with the same workflow:

• Image generation — Juggernaut XL v9 (RunDiffusion Photo v2), under the CreativeML Open RAIL-M license plus the RunDiffusion addendum.
• 4K upscale — 4xNomos8kDAT by Philip Hofmann (Phips), CC-BY-4.0.

Pack contents are redistributable as MIT-compatible material — you can use them in personal wallpapers, streams, screenshots, etc. without further attribution. The manifest entries spell out the chain in machine-readable form for anyone who needs it.
