Rank-Positional Threshold Languages: ResetStructure, Census Rigidity, and Finite Reconstruction

Let L be a prefix-closed language over a finite ordered digit alphabet, and assume that at every reachable residual the legal next digits form an initial interval {0, 1, …, d(q)}. Write Cn = L ∩ Σn , C0 = 1, and let Rn(w) be the zero-based lexicographic rank of w ∈ L ∩ Σn.
