NASA IMS test 2, peak-fault snapshot 2004-02-19 05:02 (file 975 of 984), bearing 1. Outer-race fully failed; RMS ~9x baseline, kurtosis ~17, impulses hitting the ±5 g accelerometer rail. Paired with healthy/degraded sources to expose a 3-point degradation trajectory.
Standard analysis sees: heavy-tailed; left-skewed; time-irreversible (sharp rises, slow decay). The atlas finds no named structure, but the source is distinctively extreme on Continued Fraction:log_khintchine_mean (+3.4z) — beyond what the standard bank predicts for it.
