Equal spectral distortion was not equally harmful across depth: the most sensitive layer quartile caused much more perplexity damage per surrogate-distortion unit than the least sensitive, with different depth profiles by model, and full-depth errors compounded superadditively on LLaMA.

The complete result group stays with its claim. Assessed rows come first; their judgments do not replace the whole-claim conclusion. Expand a row for conditions, sources, and evidence history.

Each row is a measurement with its reported value, latest available observation, and cumulative evidence state.
