Matched-cutoff spatial refinement
Finite-model direction survives; magnitude remains spatially sensitive
This page summarizes the linked research at its stated verification level. It is not a new proof certificate or experimental confirmation.
At one packet center, three new spatial refinements match the supplied baseline's omitted-mode energy threshold rather than mode count. Peak and whole-packet signed strain transport remain expansion-directed, but the combined-grid peak magnitude changes by −27.482%. Each new fixture has one full-S central-energy test and 32 prepared-column tests. Small equation/conservation residuals are not spatial error bounds. Tilt/hinge grids remain unchanged, closed modes remain truncated, and no continuum limit, physical particle identity, speed law or crossover energy is certified. Compare the four fixtures and separate residuals · Full methods.
