Direction-Consistency Sequel: Five-Arm Diagnostic Data (CubeAttn d2048 Perturbation)

Diagnostic data for the direction-consistency sequel study. Five-arm perturbation experiment on CubeAttn (linear attention, d=2048) investigating breakthrough dynamics: control, batch_spike (gradient amplification), and ortho_kick (parameter noise), across two seasons (Season 2: post-breakthrough perturbation t=80K-130K; Season 3: pre-breakthrough perturbation t=0-100K). Includes raw sequel diagnostics (CubeAttn d2048 at lr=5e-4 and 3e-4, linear d256, plus phi_k variants) and analysis scripts (sequel_diag.py, resurrect.py). Supports the manuscript "Direction Consistency Sequel Anatomy".
