elfpatch now stamps DT_RPATH on executables instead of DT_RUNPATH. DT_RUNPATH is consulted only for the object carrying it; DT_RPATH is consulted for every dlopen anywhere in the process. The graphics stack's load chain is three to four dlopens deep, so only the transitive tag reaches the bottom — measured, the same path content stamped DT_RPATH puts GLX, EGL, GLESv2 and headless surfaceless EGL all on the GPU, and stamped DT_RUNPATH renders on llvmpipe. Executables only. Forcing DT_RPATH on a library is measured harmful (xim-pkgindex#593) because transitivity runs downward too. All THREE platform sections, verified by PARSING the recipe rather than reading the diff — a regex edit to a .lua applies cleanly and can mean something else: linux 0.0.57=yes sha=7b24c2f156ce versions=18 macosx 0.0.57=yes sha=7b24c2f156ce versions=18 windows 0.0.57=yes sha=7b24c2f156ce versions=18 CN mirror uploaded and verified by SIZE (gitcode returns 200 with an HTML landing page for an asset that is not there, so the status code proves nothing): 147212 bytes, matching the GitHub archive. Upstream: openxlings/libxpkg#41

The loader tag now has one owner. elfpatch (libxpkg 0.0.57) stamps DT_RPATH on executables instead of DT_RUNPATH, and closure_check gains rule E to say so at install time on the user's machine when a payload arrives with the old tag. DT_RUNPATH is consulted only for the object carrying it; DT_RPATH is consulted for every dlopen anywhere in the process. A GL program reaches its driver through three levels of dlopen, so the tag — not the path — decided whether it rendered on the GPU. Of 73 installed executables on a real home, 1 carried DT_RPATH and 55 of the other 68 already carried the correct path. Also: `subos info` reports host driver drift (the detector existed as `xlings-gl-doctor` and lacked a channel), and `subos use --sandbox` without `--gpu` says the sandbox exposes no GPU — under three conditions, so it can only fire where acting on it changes the outcome. All THREE platform sections, verified by PARSING rather than reading the diff: linux latest=2026.8.10.4 arch=[aarch64,x86_64] macosx latest=2026.8.10.4 arch=[aarch64] windows latest=2026.8.10.4 arch=[x86_64] Hashes taken from the assets in xlings-res — what `XLINGS_RES` actually resolves to — not from the upstream release they were mirrored from. CN mirror uploaded from a local shell and verified by SIZE on all four platforms; before the upload all four returned 127 bytes, so the status code would have said 200 for assets that were not there.

elfpatch 现在给可执行文件打 DT_RPATH 而不是 DT_RUNPATH。
DT_RUNPATH 只对携带它的对象生效;DT_RPATH 对进程内任意深度的 dlopen 都生效。图形栈的加载链有三到四层 dlopen,只有传递性标签能到底 —— 实测:同样的路径内容,DT_RPATH 让 GLX/EGL/GLESv2/无显示 surfaceless EGL 全部到 GPU,DT_RUNPATH 则是 llvmpipe。
只改可执行文件。 在库上强制 DT_RPATH 是实测有害的(xim-pkgindex#593),传递性向下也成立。
三个平台段全部补齐,用解析验证而非看 diff:
CN 镜像已上传并按大小校验(gitcode 对不存在的资源返回 200 + HTML 落地页,状态码不是证据):147212 bytes,与 GitHub archive 一致。
