WorldOfSosal pack publishing

The public endpoint is https://store.hectic-lab.com/world-of-sosal/. Nix deploys only its landing page and nginx configuration. Pack files, the checksum manifest, and latest.mrpack stay under /var/www/store/world-of-sosal on the host and never enter Git or the Nix store.

Publish an uploaded pack

Run these commands on hectic-lab as root after the Storage Box pack has already been uploaded to a local staging path. Pick a stable version name; do not replace an existing versioned release.

set -eu
source_pack=/path/to/already-uploaded/WorldOfSosal.mrpack
version=2026-09-16
root=/var/www/store/world-of-sosal
release_name="WorldOfSosal-${version}.mrpack"
release_path="$root/releases/$release_name"

printf '%s  %s\n' \
  f8c18acb9208e4592725632ae50dab4f9c308483b34fd43a6507c74fdbf8169f \
  "$source_pack" | sha256sum --check --status
test ! -e "$release_path"
install -o root -g nginx -m 0640 "$source_pack" "$release_path.new"
mv -T "$release_path.new" "$release_path"

manifest="$root/.SHA256SUMS.$$"
(cd "$root/releases" && sha256sum -- *.mrpack) > "$manifest"
chown root:nginx "$manifest"
chmod 0640 "$manifest"
mv -Tf "$manifest" "$root/SHA256SUMS"

latest="$root/.latest.mrpack.$$"
ln -s "releases/$release_name" "$latest"
mv -Tf "$latest" "$root/latest.mrpack"

Versioned releases use a one-year immutable cache policy. latest.mrpack and SHA256SUMS disable caching so an atomic replacement becomes visible quickly. The manifest is available at https://store.hectic-lab.com/world-of-sosal/SHA256SUMS.

Import the current pack in Prism Launcher with:

prismlauncher://import?url=https%3A%2F%2Fstore.hectic-lab.com%2Fworld-of-sosal%2Flatest.mrpack

Direct URL imports do not auto-update. Repeat the publication and import steps for each new pack version.
