Sparse Model Nexus (LLM↔Quantum continuum)

One sparsity dial spans dense LLMs to the sparse-limit model — the minimal, self-contained, composable unit (“quantum”). Quanta compose via a four-operator algebra (⊕ mixture, ∘ sequential, ▷ route, ⊗ merge) under maximal self-organized criticality, planned by a receding-horizon policy over expected future frames, and honestly bounded by an undecidable Tarski residual.
