On a Windows installation I see this:

    PS C:\Users\user> ls C:\Users\user\.cache\codex-runtimes\codex-primary-runtime\dependencies\native\
    Mode                 LastWriteTime         Length Name
    ----                 -------------         ------ ----
    d-----         8/27/2026  10:09 AM                git
    d-----         6/16/2026   9:18 PM                jxrlib
    d-----         8/26/2026   7:37 PM                libheif
    d-----         6/17/2026   5:32 AM                poppler
    d-----         8/27/2026  10:09 AM                powershell

So doesn't seem bundled with all installs at least.

Is this perhaps because the aim is to read Office documents and there are (maybe, I don't know for sure) default components within Windows that can do that?
