A note on the workaround: it doesn't work on Windows unless symlinks are allowed. materializeCodexShadowHome calls fs.symlink for every entry in the shared home and has no fallback. On a Windows host with Developer Mode off and T3 running unelevated, it fails with EPERM (WinError 1314), and the instance doesn't build. On a Windows host where symlinks are allowed, the same setting works.
