FR-2026-004: TDST_WARNING — Lithospheric Stress Pre-Load Independent of Solar Forcing (Chain-of-Custody Record)

TDST_WARNING field report (chain-of-custody record). Phi_unified=0.3982, Phi_litho=0.1901 (80% collapsed — independent of solar forcing). Prediction issued May 20, 2026 02:35 UTC. Key finding: M5.9 earthquake struck 8 km E of Wadomari, Japan at 02:46 UTC — 11 minutes post-prediction, the shortest tau_release interval in the TDST dataset. Phi_solar had partially recovered to 0.8704 while Phi_litho remained critically depressed (compressed-spring configuration). This report is filed for chain-of-custody integrity. FR-2026-005 (TDST_CRITICAL, DOI: 10.5281/zenodo.20302134) supersedes in severity. Both share the same Phi_litho pre-load state and prediction window.
