2026-07-21 (VII) (CELEST.SEAM.01 WP5b executed and promoted: v498 — ``the singular vector as an operator'', the deleting object of the v497 null ideal constructed explicitly and machine-verified singular; contract now WP1–WP4 [formula in source] WP5a [formula in source] WP5b done, WP5c–e \ (roadmap); Wolfram extension [formula in source] (verified engine run); no gate closes, no marker moves, SEAM.EQUIV.01 untouched)

v498_celestial_wp5b_singular_vector.py ( CELEST.WP5B.01, 53 checks, exact integer/Fraction, deterministic, no floats). Success on the preregistered WP5b criterion: the deleting object exists and is explicit. Construction: [formula in source] (weight [formula in source] , level [formula in source] quarter units [formula in source] , an integer level) in a machine-built Chevalley/Frenkel–Kac basis — bimultiplicative [f
