+# PatchDL
+
+PatchDL is a planned standalone PS5 ELF payload for controlled official game
+patch downloads.
+
+The target design is deny-by-default:
+
+- Sony domains stay blocked by nanoDNS for the normal PS5 system.
+- PatchDL uses its own internal allowlist resolver for Sony CDN hosts.
+- Games must be explicitly enabled before PatchDL checks or downloads updates.
+- Patch selection is capped to the highest update compatible with the current
+  firmware.

+Open `web/index.html` directly for the mock UI, or serve `web/` from a local
+HTTP server.
