      "description": "Calculate Delta Economic Value of Equity (EVE) under the 6 BCBS d368 / EBA standardised IRRBB shock scenarios (parallel up, parallel down, short up, short down, steepener, flattener), recalibrated effective 1 Jan 2026. Duration-based sensitivity over 6 standardised repricing time buckets using a 200bp reference parallel shock and the BCBS d368 Annex 2 short/long tenor scalars. Returns per-scenario delta_eve, worst_scenario, and worst_delta_eve. Root node of the irrbb-supervisory-outlier-test chain. BCBS d368 (2024 recalibration). NaN-safe. Zero network, zero PII.",
