Enum Refusal 

pub enum Refusal {
    TerminalLibrary,
    GlibcProgram,
    WindowOnDebianOnly,
}

Why a harness is not offered on a system: what was measured when it was tried there.

Variants

TerminalLibrary

The harness installs, and the terminal library it opens every shell command through is a glibc build that takes the whole program down on musl. Gemini CLI on Alpine: its @lydell/node-pty-linux-x64 has no musl build, and loading it into Alpine’s Node ended the process with a segmentation fault (measured 2026-09-22 with 0.60.0). Qwen Code, Gemini CLI’s fork, carries the same library: on Alpine it started, and the first shell command typed into it ended the program (measured 2026-09-23 with 0.24.4; loading the library alone faulted).

GlibcProgram

The application is a glibc program and the system has no glibc loader, so it does not start at all. Antigravity IDE on Alpine: its program asks for /lib64/ld-linux-x86-64.so.2, which Alpine does not have, and the shell answers not found (measured 2026-09-22 with 2.5.5).

WindowOnDebianOnly

The application opens a window, and that window has been measured on Debian only: the packages it needs, the image’s size, and that the window really comes up. On another system none of that has been seen, so QCode does not build it there.
