 - 📦 **PURL-native** — [ECMA-427](https://github.com/package-url/purl-spec) identifiers as first-class input
 - 🏷️ **Normalized data model** — same `Package`, `Version`, `Dependency`, `Maintainer` types everywhere
 - 💾 **Storage-backed cache + lockfile** — unstorage-native, sha256 integrity checks, configurable TTL

 Scoped packages work as expected: `pkg:npm/%40vue/core` or `npm/@vue/core` in the CLI.
 
+Arch Linux packages use a namespace: `pkg:alpm/arch/pacman` (or just `pkg:alpm/pacman`) for official repos, `pkg:alpm/aur/paru` for AUR. Official packages default to `arch` when the namespace is omitted; AUR requires the explicit `aur` namespace.
