description: "Evaluate the Net Interest Income (NII) leg of the EBA Supervisory Outlier Test: the worst-case 1-year delta NII under parallel up/down shocks versus a caller-supplied threshold (EBA leaves NII SOT calibration to competent-authority / institution discretion under EBA Guidelines on IRRBB and CSRBB, EBA/GL/2022/14 -- no single EU-wide bright-line percentage exists, unlike the EVE leg). Returns delta_nii_pct_of_nii, threshold_set, and nii_outlier. Terminal node of the irrbb-supervisory-outlier-test chain. Exports as Policy Mandate JSON or W3C VC. NaN-safe. Zero network, zero PII."
