DCRP75/X72R58: Packet-Centered Pressure Work and the T→X Confluence Bridge

Continuing from DCRP74's proposed 'scale-matched counterflow conveyor' as a candidate zero-stretch T equality, this round rules out the two simplest ways it could stay silent toward X72. First, it proves that the material pressure work can be properly decomposed into a packet-wide translation term Mb·g and a genuinely internal pressure-curvature work Π_P° (which admits a paired-increment representation and is sensitive to the pressure Hessian), completely quotienting out all affine pressure jumps. Second, it proves that any closed, nonzero-vorticity, zero-stretch packet must carry a strictly positive pressure-gradient increment and Hessian-curvature budget, so pure affine pressure alone cannot sustain DCRP74's counterflow conveyor. More strongly, the actual D72/D73 cylinder-mosaic state continually satisfies SΩ=0, so DCRP62 gives E_pΩ=-|Ω|²Ω/6 directly, and hence |E_p|²≥|W_Ω|²/24 holds pointwise — this explicit zero-stretch T conveyor is therefore already an X72 defect state. A T-residual branch genuinely independent of X must instead draw on nonzero stretching, alignment collapse, or genuinely non-closed material replacement, leaving DCRP76 to test the route of 2γ stretch resonance.
