Wallpapers and templates
GoldenNugget imports PosterBoard wallpaper packages as .tendies and template packages as .batter. Use the PosterBoard page to import them. Wallpapers are handled separately from presets.
Before importing a package, click Check Package… on the PosterBoard page. The checker reads the archive structure and reports path, ZIP, descriptor, and supported document-syntax problems. You can save its report as JSON. A passing static check does not guarantee that a wallpaper will look or behave correctly on a device.
CLI checks
python nugget_cli.py wallpaper validate wallpaper.tendies --json
python nugget_cli.py wallpaper validate template.batter --ios-version 27.0 --json
The checker does not extract or run package contents. It warns about embedded PosterBoard databases, external script references, and older package families. See package format documentation.
