The Dark Sector in Computational Finitism: A Framework and Its Open Problems

We present a framework for the dark sector within Computational Finitism. The framework has two components. First, the Topological Redundancy Buffer (TRB) of the electron's algebra E drains into a noise field whose equilibrium density is (or in the normalization of prior work). This noise field is the natural candidate for the dark sector: it does not couple to the Fano channels (invisible to ordinary matter), it has energy density (gravitates), and it accumulated during the Big Bang crystallization (frozen in at ). Second, the algebra admits a second chiral solution G with instead of . G contains stable elements that annihilate the Fano sector. These are mathematically natural dark matter candidates. We test both components against the observed cosmological ratio . We find a numerical match from the framework: , where 7 is the Fano point count, and 33 is a combinatorial factor from the electron's neighborhood. This match is presented as an empirical observation, not as a derivation. The paper closes with an honest list of what remains open: the correct derivation of the 7/33 factor, the mass scale of the dark sector, the physical realization of G, and the abundance calculation. The framework is coherent, falsifiable, and does not overclaim.
