Determine whether high-frequency reconfiguration contains unpriced structural information
Determine whether the high-frequency component of the reconfiguration index contains structural information that is simply unpriced, rather than being dominated by re-estimation noise, by directly testing the direction of eigenspace increments rather than only their magnitude.

Whether it also carries structural content that simply goes unpriced is not settled here: the autocorrelation of the magnitude series is consistent with contamination but does not establish that the increment is noise-dominated, and separating the two would require a direct test on the direction of the increment rather than its size.
