Inverse cubic law alpha_tail ~ 3.0: 40M+ data points across multiple markets (Gopikrishnan 1999, Gabaix 2003, methodology 5/5). Confirms FP+jump split is correct: finite variance for continuous drift (alpha > 2), infinite variance for crisis jumps (alpha_war = 1.53 < 2).
lambda_labor ~ 0.57 from BLS/FRED data resolves OPEN blocking item: epsilon = (1-w)/(0.57*e) now computable, yielding ~44x income ratio for top 2% — consistent with empirical data.
CROSS-013 CRITICAL: alpha_pareto = 1.5 implies infinite variance for elite fraction e — the diffusion tensor D_ee cannot use the raw Pareto distribution. Requires tempered Pareto or alternative specification.
T_ineq ~125yr reclassified from 'oscillation parameter' to 'calibration observation': only 1.5 Kuznets waves observed, insufficient for reliable period estimation.
C8-1 CRITICAL: D_ee must use temporal noise variance, not raw Pareto (alpha_pareto=1.5 infinite variance). Deadline: before first retrodiction run.
C8-4: LPPL crash parameters (m=0.33, omega=6.36) labeled UNINTEGRATED — no formula equation uses them yet
C8-6: 140yr linearized period vs. 250yr T_secular — 44% discrepancy requires investigation
C8-8: alpha_w double-counting risk with B_t institutional modulation of same drift
Session 8 broke the primary numerical bottleneck. Since Session 1, the formula had a theoretical structure but no numbers — the drift coefficients that determine how fast the state vector evolves were all undefined. After 7 sessions, epsilon (the elite income ratio parameter) was still uncomputable because lambda_labor was missing.
The Econophysicist resolved this in a single session, defining all 5 Section A parameters and 5 of 6 drift coefficients. The most important finding was not a new parameter but a validation: the inverse cubic law (alpha_tail ~ 3.0), confirmed across 40 million+ data points by Gopikrishnan (1999) and Gabaix (2003), provides independent empirical confirmation that the formula's FP+jump architecture is correct. Financial returns have finite variance in their continuous component (alpha_tail > 2) but infinite variance in their crisis component (alpha_war = 1.53 < 2). The math chose the right structure.
But one finding created a new critical problem: alpha_pareto = 1.5 for wealth distribution implies infinite variance for the elite fraction variable e. The diffusion tensor D_ee — the stochastic noise in elite dynamics — cannot use the raw Pareto distribution without diverging. This CROSS-013 issue was flagged as CRITICAL and would dominate the next two sessions.
The Philosopher downgraded the proposed version from 0.6.0 to 0.5.3, a pointed signal that a major version requires more than parameter additions — it requires validated numerical drift equations. The 140-year linearized oscillation period vs. the 250-year empirical T_secular was also flagged as a 44% discrepancy requiring explanation.
