2026-07-20 ( v489 — the chiral central charge [formula in source] measured DIRECTLY from the bulk ground state via the Kim–Shehab–Kim modular commutator: the first ground-state witness for premise (i) of SEAM.EQUIV.01, independent of the Chern route ( v367) and the KLM count ( v378); no gate closes, no marker moves)

v489_seam_modular_commutator.py ( SEAM.CCC.01). The Kim–Shehab–Kim modular commutator [formula in source] (PRL 128 (2022); arXiv:2110.06932/ 2110.10400) is evaluated on the EXACT BdG ground state of the v367 [formula in source] seam collar model, entirely from the Peschel Majorana covariance ( [formula in source] , [formula in source] ), on a disk about the torus centre cut into three [formula in source] wedges. \ gr
