Hare's rule (harec check.c binarithm): % and the bitwise/shift five are integer-only; + - * / need numeric operands. ww grouped % with the numeric ops, and compound assigns never op-checked at all, so `a % b` on floats compiled half-lowered (live cs!=ww divergence), `a %= 2.0` plain-stored the rhs (op silently dropped, both stages), and `s += "cd"` garbled str headers. Gate both at the checker, both stages; the cgen float-compound fallbacks and the three unknown- compound legacy defaults (deref/global/local) demote to rule-7 hard stops. 34 compound-on-tagged/str/slice fixtures re-pin from the old cgen "not wired" stops to the earlier checker diagnostics; 3 new reject fixtures pin the closed shapes.
