Every stack movement now goes through pushv/popv and increments a depth word on the function context. A call pads to 16 from wherever the expression evaluator has left rsp, and asserts the parity before it emits the call. The nested probe passes. The stack-argument path is folded into the same counter rather than keeping its own, because two independent notions of parity is how the bug comes back.
