v5.4.1
Released as v5.4.1 (Oct 2026): how to read the wealth result. Words only. No figure, row or engine line changes from v5.4, and the panels and release data are v5.4's. Plain-words report for Duke: dev/reports/v5-24-wealth-measure-reading.md; decision: dev/DECISIONS.md, session 1c.
- Why the 20-year wealth gap grew in Reference (+11.0 points against v5.3's +5.5). The v5.4 report and notes now name the cause: mostly the 10% lower pay on return to work. Without that cut the gap is +6.6, with a 20% cut +15.7, and the new PTH and PTF rules move it by less than 0.3 (readings
cut0,cut20,pthbold,ptfs25indev/runs/release-panel.json). - "How to read this measure" (release page, under the Savings result, id
rel-wealth-frame). The note gives Duke Johnson's framing: with the basics guaranteed and work more optional, people need a savings reserve less, and the gain shows in how people live more than in dollars. It cites outside evidence that a guaranteed minimum lowers emergency saving (Hubbard, Skinner and Zeldes, 1995). It states that the model does not include this: the spending share is the same in both runs, no well-being is measured, and the gap comes from prices against unprotected savings and from lower pay after job loss. The verdict line is unchanged. - v5.4's notes are in CHANGELOG.md.
