  "scope_note": "Not a stated figure: regulation 8B gives a rule, and every value here is our computation of it from `employment.rpi.all_items` (D14, D24), recomputed by the build. Published to three decimal places, which is a READING and not a rounding the regulation states: regulation 8B rounds nothing, and regulation 8C(1)(b) makes its worked example (\"2.4% … 0.024 … 1.024\") illustrative only. The record reads \"the percentage increase in the retail price index\" as the one-decimal percentage the ONS publishes as the index's 12-month change, computed here from the archived index — the reading that reproduces the thresholds HMRC publishes: an unrounded quotient would put the plan 1 threshold at £26,070 for 2025-26 and £26,910 for 2026-27 rather than the £26,065 and £26,900 in force. Starts with the year ending 5 April 2025, the first year any threshold in this corpus derives (both bases are stated for 2023-24); the series window opens at March 2022 for the same reason.",
