P-027Can the staircase of a deep linear network's loss be read backwards, as a measurement of a chosen spectrum?probe
P-028Is the period-doubling past the edge of stability Feigenbaum's cascade, and in what dimension does that stop holding?probe
P-029Is the double-descent spike at p = n quantitatively the Marchenko–Pastur edge?probe
P-030Do a primality classifier's residual errors fingerprint its algorithm — Fermat pseudoprimes for a Fermat-like test, no-small-factor composites for a sieve?probe
P-031Grokking multiplication on the units of Z/561 — which characters appear when the group is not cyclic and no discrete log exists?probe
P-032Do a learned Franklin involution's errors concentrate exactly on the pentagonal-number shapes where the map is undefined?probe
P-033Under weight decay, does a partition-recurrence readout become sparse exactly on the generalized pentagonal lags, with alternating-pair signs?probe
P-034Eta's coefficients indexed by n versus by m — is one coordinate trivial and the other near-impossible?probe
P-035Are learning-curve shapes exactly two kinds — spectral readouts and competitions between coexisting solutions?probe

N-031MPS and CPU training diverge for the same seed in R26_training_dynamics — so a retrain meant to reproduce 037's W_E must run on the same device, and be checkednote
