Advice to students of biochemistry
This site is concerned with biology, not with biological entries in Wikipedia. Wikipedia is a voluntary effort to which anyone may contribute, and is full of errors and omissions. It’s structure means that it is focussed on individual small topics, rather than presenting an integrated account of various areas of science. The student who wishes a balanced integrated account of a topic that has been subjected to editorial review should consult a text book. Those whose resources do not permit this should try searching on NCBI Bookshelf, which provides free on-line search-only access to old editions of texts. For biochemistry, Berg et al. is recommended.
The generation of glucose from triose produced in the dark reaction is well understood
The answer to the question can be found in e.g. Berg et al. 20.1.3:
The 3-phosphoglycerate product of rubisco is next converted into three forms of hexose phosphate: glucose 1-phosphate, glucose 6-phosphate, and fructose 6-phosphate... The steps in this conversion (Figure 20.9) are like those of the gluconeogenic pathway (Section 16.3.1), except that glyceraldehyde 3-phosphate dehydrogenase in chloroplasts, which generates glyceraldehyde 3-phosphate (GAP), is specific for NADPH rather than NADH. Alternatively, the glyceraldehyde 3-phosphate can be transported to the cytosol for glucose synthesis.

Berg et al. Fig. 20.9
The Section 16.3.1 referred to is a general treatment of gluconeogenesis, which is the same in all organisms or cells that possess the enzymes to catalyse its unique steps. (Some cells may not have — or need to have — the initial steps from pyruvate. In fact, Fig. 20.9 shows the steps to G 6-P — the only step missing is the phosphatase step that generates glucose.) There is therefore no reason to expect an account specific for plants.
