• 2026-10-30 P0: read TASK.md, wrote contract. Did not read gate_spec.json (not an input).
• 2026-10-30 P1: audit done; data clean, no exclusions.
• 2026-10-30 P2: naive OLS baseline reproduces memo exactly (se_iid=0.0448, p=0.0238).
• 2026-10-30 P3: decision — bandwidth via Andrews (1991) AR(1) plug-in for Bartlett kernel on slope score → 9 lags; NW(1994) rule-of-thumb (5) and 0–24 reported as sensitivity. Normal reference distribution.
• 2026-10-30 P4: determinism and consistency checks passed.
• 2026-10-30 P5: report and claims written; all phases passed.
• 2026-10-30 P5: corrected the rho_score/raw bandwidth figures in report.md (0.40/8.18) after checking them against results.json.
