Released as v5.4 (Oct 2026): labour and markets. One pull request into main (merging is the release). Plain-words report for Duke: dev/reports/v5-23-v54-release.md; the design note is dev/reports/v5-21-v54-design.md.

  • Job loss and re-employment (EMPL): Current Population Survey flows and spell lengths, unemployment insurance in both runs, a 10% pay cut on return, automation through job loss, 700 occupations.
  • PTH's balance sheet (PTHB): homes, mortgage debt, members' and community equity, with an enforced yearly identity; equity growth capped at inflation + 2%; members leave at 6.2% a year.
  • PTF by sector (PTFS): food and utilities at the Hub's epsilons, other sectors no cut (swept); members leave at 3.2% a year.
  • Risk measures (RISK, reporting only): drawdown, recovery time, re-entry into poverty.
  • Figures (Reference, 20 years): adult-years below the cost of living 49.2% → 19.6% (−29.6; v5.3: −28.3); too little wealth +11.0 points (v5.3: +5.5), +0.8 at 40 years. Job loss changes the no-programme run too, so compare within a release. The cause of the larger 20-year wealth gap in Reference is not yet isolated.
  • Provenance: 500 seeds, engine fe88599 clean, run in 33 pieces (dev/tools/v54_jobs.sh, merged with dev/tools/merge_parts.py; pieces in BetterToBest/compassionism-sim-results, v54-fe88599/).
  • v5.3.1's notes are in CHANGELOG.md.
