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. Upstream: openxlings/xlings#536, openxlings/libxpkg#41, mcpplibs/mcpp-index#202

加载器标签现在有唯一的所有者。
elfpatch(libxpkg 0.0.57)给可执行文件打 DT_RPATH 而不是 DT_RUNPATH, 新增 rule E —— 当载荷带着旧标签到达时,在用户机器上、安装时说出来。
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。GL 程序要穿三层 dlopen 才够到驱动,所以决定它在不在 GPU 上渲染的是标签,不是路径。真机 73 个已安装可执行文件里 1 个 DT_RPATH,而另外 68 个里有 55 个路径本来就是对的。
另有两项可观测性:
subos info报宿主驱动漂移(检测器早就存在,缺的是通道),subos use --sandbox不带--gpu时说明沙箱没有 GPU —— 三个条件,只在采取行动能改变结果时才响。三个平台段全部 bump,用解析验证而非看 diff:
哈希取自 xlings-res 上的文件(
XLINGS_RES实际解析到的地方),不是它镜像自的上游 release。CN 镜像本地上传并按大小四平台核对通过 —— 上传前四个都返回 127 字节,所以只看状态码会对不存在的资源报 200。
