Improve LLM summary for SSI

This household receives $8,958 from SSI, but the explanation reads:

Explanation
SSI (Supplemental Security Income) is a federal program that provides financial support to low-income individuals who are elderly, blind, or disabled.

The simulation result shows that the reported SSI value for 2025 is [0. 0.], indicating no projected change in SSI benefits or eligibility criteria for that year.

This outcome likely stems from:

No scheduled increases in SSI payment rates
Stable eligibility thresholds
Unchanged income and resource limits
Key factors in SSI calculations include:

Federal Benefit Rate (FBR)
Cost of Living Adjustments (COLA)
Income and asset limits
To alter this result, policymakers might consider:

Adjusting the FBR
Modifying income exclusions
Changing resource limits
Implementing new COLA methodologies
These changes could impact SSI eligibility and benefit amounts, potentially leading to non-zero values in future simulations.

Start with the linked household result and trace where the SSI LLM explanation is generated; the issue names no source file, test, or entry point. Reproduce the reported $8,958 case and verify that the summary describes the actual SSI result instead of claiming a zero value.
