Frente rust, fase climb: la toolchain mrustc-bootstrapped 1.90.0 (host musl) ya sirve de stage0 para construir rust 1.91.0 con el bootstrap real (x.py). - bootstrap.toml: build/host/target=x86_64-unknown-linux-musl, stage0 rustc/cargo = prefix run_rustc 1.90.0 host-musl, LLVM 20.1.8 reusado vía llvm-config (pasa el gate >=19, sin rebuild de LLVM), crt-static=false (link dinámico contra el musl del devfs, como Alpine y la toolchain de run_rustc), rpath=true. - run-xpy.sh: corre x.py en el sandbox devfs (bind /src, /out, /mrustc) para que resuelvan los paths de stage0 + llvm-config del bootstrap.toml. - README: documenta ambos. dry-run de x.py VALIDADO (stage0 pasa el version-check minor+1, LLVM hallado, target ok). Build stage-2 de 1.91.0 EN MARCHA en background. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
