The database drops the duplicate PS3UPDAT.PUP entry and regains
adler32 on every file. RetroPie gains an install manifest, so the
download table reports its size instead of a dash.
Every other manifest field was treated as hostile input, but
standalone_copies targets were only length-checked before being
expanded and written to: a traversal component or a symlink already
sitting at the destination sent the copy outside the directory the
user opted into. Targets are now validated like the other paths and a
symlinked destination is never followed.
RETROBIOS_BASE_URL serves the manifest and the files it declares, so
it now has to be HTTPS the way both bootstraps already require of the
installer URL; loopback stays open for the end-to-end tests.
install.ps1 left TLS at the Windows PowerShell 5.1 default, which
GitHub refuses, so the download failed before any hash was checked.
check_local read every file once per declared digest, single threaded.
One read now feeds both, across the same pool the downloads use.
RetroPie had no manifest, so the one-line installer answered 'unknown
platform' for a frontend whose packs do ship.
