Public endpoint

The catalog is served via jsDelivr, which mirrors GitHub raw content over a global CDN with a 12-hour edge cache:

https://cdn.jsdelivr.net/gh/xt0n1-t3ch/DLSSync-Manifest@main/manifest.json

DLSSync consumes this URL by default. Override at runtime via the DLSSYNC_MANIFEST_URL environment variable.

Upstream sources

The cdn_url field on every release points to the upstream GitHub release asset or NuGet flat-container URL. This repo does not mirror DLL binaries — DLSSync downloads them directly from the publisher, verifies the SHA-256 against the manifest, and verifies the Authenticode publisher subject at install time.

Schema

The manifest validates against manifest.schema.json (Draft 2020-12). The current schema version is 2. Each release entry carries:

{
  "version": "310.6.0",
  "version_packed": 87169138736103424,
  "filename": "nvngx_dlss.dll",
  "sha256": "<64-hex SHA-256, or 32-hex MD5 for dlss-swapper-sourced entries>",
  "size_bytes": 1234567,
  "signed": true,
  "released_at": "2026-04-15T00:00:00Z",
  "source": "NVIDIA/DLSS@v310.6.0",
  "cdn_url": "https://github.com/.../release/asset.zip",
  "release_notes": "...",
  "signature_subject": "NVIDIA Corporation",
  "channel": "stable",
  "is_dev": false,
  "min_driver": null
}

Why a separate repository

1. The manifest rebuilds on an hourly cron. Keeping it in the app repo would pollute the git log of the application code with hundreds of chore: rebuild manifest commits.
2. jsDelivr caches per commit SHA. Refreshing the catalog should not invalidate the app's CDN entries.
3. The catalog is a public service — other tools (Vortex extensions, CLIs, mod managers) can consume it without depending on the app codebase.

Build locally

The builder lives in the app repo, not here:

git clone https://github.com/xt0n1-t3ch/DLSSync.git
cd DLSSync
cargo run --release -p manifest-builder -- --out manifest.json

Then validate against the schema:

npx --yes ajv-cli@5 validate -s manifest.schema.json -d manifest.json --strict=false --spec=draft2020 --all-errors

License

Apache-2.0 for the catalog metadata, schema and workflows. Each linked DLL retains the EULA of its original publisher (NVIDIA, AMD, Intel, Microsoft). The manifest does not redistribute DLL binaries; it indexes their authoritative upstream locations.
