- New paper papers/even_level_graph_generators/: defines Even Level Graph (every level cycle even), derived level graphs, intertwining trees, and the disjunction conjecture (every maximal planar graph is a derived level graph or intertwining tree). Empirically tested through n=11: every iso class is at least an intertwining tree, so the disjunction holds trivially in this range. The intertwining tree disjunct fails at the Tutte graph dual (n=25), so the disjunction becomes non-trivial past some unknown threshold. - Level Switching paper: adds Section 4 (Reachability via edge switches) with the two-step argument (Sleator-Tarjan-Thurston for Case 1; face-merges for Case 2) and Theorem 4.1 (O(n) edge switches suffice to reach all-depth-0).
