Iteration analysis after the classical ladder

Summary

A read-through of CSP, FBCSP, Riemannian tangent-space LDA, truncated SVD+SVM, and EEGNet on the Nieto Inner Speech set.

What transferred

Subject-wise splits stayed honest. The classical ladder ran end-to-end with logged configs.

What collapsed

Leave-session-out accuracies stayed near chance across the board. No recipe on scalp EEG alone cleared a decoder go/no-go.

Next gate

Controls, alternate data, and different feature assumptions before hardware integration.
