+`var_arm64` has three states. **Only claim `yes` when it has actually been run on
+arm64** — the mere existence of an arm64 artifact is not verification:
+
+- `yes` — verified working, proceeds silently
+- `no` — known broken (x64-only artifact, x86 dependency, CUDA), aborts
+- *unset* — never tried. The user is told so and asked whether to attempt it
+  anyway, with a pointer to report the result. Aborts non-interactively.
