// issue 0105 / F3 — the const cycle guard must key on (name, AUTHOR-source), not
// name alone. `a.sx` declares `M :: 1` and `K :: M + 1` (= 2). `b.sx` flat-imports
// `a.sx` and declares a DIFFERENT same-name `M :: K + 1` (= 3) — so the SAME name
// `M` appears at two levels of one fold chain, in two different modules
// (b's `M` → a's `K` → a's `M`). A name-only cycle guard sees `M` twice and trips
// a FALSE cycle, folding b's `M` to null → the array dimension `[M]u8` becomes a
// non-const error. Keyed on (name, source) the two `M`s are distinct, so the
// chain folds: `m=3 len=3`, coherent for the value read and the dimension.
