Design specification (v2.0) of the particle data structure for the central projection framework. Major revisions from v1.0: (1) reinterpret xyzt axes as vibrational frequencies (not wave numbers/acceleration), (2) add δV (phase displacement) and δδt (processing-period change) to the Particle structure, (3) introduce Mesh structure to separate longitudinal modes (Higgs, gravitational waves) from Particles, (4) eliminate special status of t-axis with full 6-axis symmetry. All operations close under int256 integer arithmetic. Bilingual (Japanese / English).
