spike-solutions

Unpolarized Gowdy spike-sector test finding a converged localized mismatch for four-function VTD data while leaving the ordinary region architecture-limited.

Almost-everywhere and centered-spike architecture with three-resolution slices, diagnostic figures, and independently verified nonclosure.

Exact true- and false-spike known-answer controls validating amended formulas and centered reconstruction while exposing translation/periodic-domain nonclosure.

Dual-scale exceptional-footprint test localizing a growing unpolarized Gowdy feature while showing the sealed history is too short for asymptotic scoring.
