  "hypothesis": "The complete two-permutation 150-set representation may be more effectively navigated by steepest legal bipartite 2-switches than by the random annealing plateau of TERRA-EXP-0002.",
  "method": "From a two-permutation state, select a random row and one of the two permutation layers. Evaluate every legal image transposition in that layer, using the same exact incremental collinear-triple objective as TERRA-EXP-0002; apply the strictly best improving swap and stop the restart on a no-improving selected row. Verify each restart endpoint by exhaustive integer determinant enumeration.",

Exact endpoint counts were 100,106,109,92; global best 92. Wall 18.55 s, user CPU 18.97 s. A preliminary corrected 2x500 calibration gave 100 and108. No 150 candidate.",
      "status": "FAILED",
      "interpretation": "Each selected row/layer exhaustively considered all legal transpositions, but this strict-improvement descent was worse than TERRA-EXP-0002 random annealing's 83 best conflicts. Endpoints were independently checked by all C(150,3) integer determinants and matched the incremental objective exactly. This falsifies the practical claim that this greedy neighborhood improves the prior annealing at this budget; do not extend the identical descent. It does not exclude any 150 configuration or other two-permutation search methods.",
