Ambos hops del climb construidos con el bootstrap real (x.py) en el sandbox devfs,
reusando LLVM 20.1.8 externo en todo (gate >=19) — sin rebuild de LLVM:
mrustc → rustc 1.90.0 → rustc 1.91.0 → rustc 1.91.1
- hop 1 (1.90.0→1.91.0): bootstrap.toml, stage0 = prefix run_rustc musl-host
1.90.0. stage-2 + install → rust-1.91.0-prefix relocatable (rpath).
- hop 2 (1.91.0→1.91.1): bootstrap-1.91.1.toml, stage0 rustc = el 1.91.0 instalado
(bind ro /stage0 vía STAGE0), stage0 cargo = el 1.90.0 (pasa el check minor-1).
extended+cargo. FIX cargo-native-static=true → feature all-static (openssl/curl/
libgit2/libz vendored desde fuente vía gcc), el devfs hermético no tiene OpenSSL.
- run-xpy.sh: añade bind ro opcional /stage0 (env STAGE0) para el stage0 del hop.
VERIFICADO: rust-1.91.1-prefix/bin/{rustc,cargo} corren standalone (solo prefix
montado, rpath). rustc 1.91.1 (ed61e7d7e) host x86_64-unknown-linux-musl LLVM
20.1.8; cargo 1.91.1. Smoke-test compila+corre. Es la versión EXACTA de Alpine,
auto-alojada desde la cadena mrustc. Cada hop ~45min (LLVM reusado).
NEXT: swap rust 1.91.1 en /toolchain + criterio de auto-consistencia (EXPECT_REF).
