New auxiliary formalization for the ResourceScheduling Q2 reduction. The target is the unchanged CookPvsNP one-tape machine model, following Cook, The P versus NP problem, Clay Mathematics Institute (2000), Appendix. This explicit finite-column stack compiler and its simulation lemmas are new contributions, not numbered claims from Cook or the scheduling source paper.
