We propose that dark matter is not a single substance native to our universe, but a spectrum of matter types that originated in shallow shells of the Chute—a recursive structure of nested black hole interiors described in the parent framework (Barkley, 2026). In this model, our observable universe occupies Shell 7 in a 10-shell chain. Matter types native to Shells 4 through 6 leaked through event horizons into our shell during and after the shell transition event that created our universe. This immigrant matter gravitates (gravity crosses shell boundaries) but does not couple to Shell 7 electromagnetism, which is a shell-local force. The result is matter that is gravitationally present but electromagnetically invisible—precisely the observational signature of dark matter. This framework makes several distinctive predictions. First, dark matter comprises multiple types with different properties, each reflecting the physics of its shell of origin, resolving persistent small-scale structure problems in ΛCDM cosmology including the cuspy halo problem, the too-big-to-fail problem, and the diversity of rotation curves. Second, the observed dark-to-baryonic mass ratio of approximately 85/15 is derived from the shell structure rather than assumed as a free parameter: approximately four matter-producing shells, each converting ~4–5% of inherited matter, yield a cumulative ratio of ~84/16. Third, the decades-long failure of direct detection experiments is reinterpreted not as insufficient sensitivity but as a categorical impossibility—detectors built from Shell 7 matter cannot interact with matter from Shells 4–6. Fourth, the unexpectedly massive and mature galaxies observed by JWST at high redshift are explained by inherited dark matter scaffolding that was already in place at the time of our Big Bang.
