The Two Walls Are Two: #337's Stations Cannot Feed #325's Test, and Each Wall Stands With the Other Torn Down

Works target NT-A5 (tau_confine: the two walls are one wall?) at DERIVED-INDEPENDENT grade, the target's ceiling. Parents: paper #325 (Q_c proved not a function of the record from the tube constitution: the bundle Q_c^-1 = Q_ps^-1 + Q_disp^-1 + Q_drain^-1, the countermodel pair spanning the price 2601.10 across admissible end completions) and paper #337 (the loss ledger run along the load at seven stations: a finite tau_confine at no station, because the radiate history factor H is unpriced in-corner in [0, H_fill(phi)] and tau goes as 1/H^2). Gated first on both parents' printed exhibits, recomputed digit-for-digit. The commissioned expression attempt fails at the slot level: #337's station data fill 0 of #325's 3 test slots at derived grade (its Q_tw and Q_vio are the radiate channel's stores; radiation is neither dispersal nor drain, and #337 contains the words drain/dispersal zero times), touching the phase-slip slot in shape only (cap exponents differ by g(1)/A_ps = 50.00 / 69.31 / 82.84; the coincidence g_100(1) = 0.01 = A_ps is exhibited and refused). Run at all seven stations under the strongest grant, the bundle still spans the price (closed ends: log10 Q_c 7.2914e34 to 1.4990e36, above; geon-rate ends: below sqrt(3), below). Independence is then proved by total removal in both directions: granting all of #325's missing inputs (core fixed with j = a_c = 1, junction law, dispersal data) leaves #337's wall standing (radiate time at the cap 6.605e-11 s at H_fill, 6.605e-9 at H_fill/10, 6.605e-7 at H_fill/100, unbounded at H = 0); granting all of #337's missing inputs (H priced as H_fill(phi), j = a_c = 1; radiate times 2.113e-4 s down to 6.605e-11 s across the stations) leaves #325's wall standing (the bundle still spans 2601.10). The missing lists share one source, the core completion, which closes neither wall. Cross-citation printed as commissioned: paper #337 does not cite paper #325 (zero mentions counted from the files, both ways). The P-01 confinement hole has two doors. tau_confine remains NOT PRODUCED; producing-count 0. Computation only; no design or application content. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
