 -- xpm PLATFORM level because mcpp materializes `[xlings] deps` for the ROOT
 -- project only, so a consumer running `mcpp add riscv-virt-rt` would otherwise
 -- get a board package with no way to start it.
+-- ⚠️ 0.4.0's `nolibc` template generates a project that does not run. The
+-- scaffolder injects the template's own package as a dependency, and this
+-- package's module includes <stdio.h> — so on a target with no C library the
+-- injected dependency fails to compile before the generated project is
+-- reached. 0.4.1 declines the injection (`[template.inject] self = false`,
+-- mcpp 2026.8.20.2+) and stops treating an absent C library as an error, while
+-- still supplying the emulator. 0.4.0 stays listed; its default template is
+-- unaffected.
