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.
• Install actions are source-aware: shadowmounted and unknown titles are never installed by PatchDL.

Source Classification

PatchDL treats the title source as part of the safety policy:

official     check/download/install allowed
external     check/download/install allowed when detected as a real install
shadowmount  check/download allowed, install blocked
unknown      check allowed, download/install blocked

The future ELF scanner should classify titles by app metadata plus mount table inspection. Shadowmounts should be detected through statfs() / getfsstat() and nullfs mount origins instead of trusting title IDs alone.
