Interval maps generated by erasing block substitutions

The candidate solution reproduces, in essence, the paper’s constructions: it uses the same σ-gluing mechanism (Lemmas 4.2 and 4.5), derives dense orbits, 1/2-sensitivity, and dense periodic points (hence Devaney chaos), builds an uncountable scrambled set (Li–Yorke chaos), proves infinite topological entropy under lim |w|/ε(w) = ∞, and identifies an almost fixed point at x0 = 0.wε^∞. Minor overstatements in the candidate (e.g., claiming ≥1/2 separation in the Li–Yorke construction and “both” left/right accumulation at x0) go beyond what’s proved in the paper, but do not invalidate the main conclusions.
