||| DISCHARGED: spec anchor — the 9 ref characters forbidden by
||| git-check-ref-format. `forbiddenRefChars` is `public export` with
||| this exact list literal as its body (SafeGit.idr L24-26), so the
||| elaborator unfolds the LHS to the RHS for `Refl`. No "Char-list
||| reduction" is needed — both sides are the same list literal.
