A str field reached through a chained dot (o.i.s) emitted two loads (ptr, len) and stored a stale CX as the cap — both stages, at any non-zero chain depth. Emit the full header at the chained-dot leaf. Review item #29. Both stages move in one commit: one emission contract; splitting would leave the byte-id gates red between the halves.
