  "fields": {
    "annual_value_usd": "Then-year nominal dollars. GS values use the selected new-hire after-FERS basis; military values use the selected taxable-salary-equivalent basis.",

    "parity_gap_vs_gs12_step1": "Comparator index divided by the GS-12 step 1 index, minus one. This measures relative growth, not job equivalence.",
