# Appendix B — Source Ledger

**Manuscript:** *The Conditional Frontier: A Same-Standards Comparison of Capitalist and Socialist Institutions, 1945–2025*
**Principle:** No claim, statistic, or citation enters the manuscript unless it traces to a verified entry below. Every entry was checked against an authoritative source via live retrieval during research. `confidence` carries forward to the prose: `contested` and `single-source` claims are hedged; `UNVERIFIED` items are not used as load-bearing facts.

**Ledger status:** 41 entries. Theory/primary-text rows gathered in Stream A (before case-universe freeze); dataset/empirical rows gathered in Stream B (after freeze). Verification pass (Citation Auditor) recorded in `04_review/citation-audit.md`.

### Carried flags (govern hedging in prose)

1. **Lavoie1985 verdict** — the "Austrians won the calculation debate" claim is a *position*, not consensus; the computational-planning revival (DapprichCockshott2023) keeps it live. Present symmetrically.
2. **StucklerKingMcKee2009** — report as *association*; note the published *Lancet* methodological challenges; do not state as established causation.
3. **DPRK figures (BankofKorea2023, GoodkindWest2001)** — estimates under data opacity; give ranges, attribute to estimating body.
4. **Cooperative productivity** — evidence is **mixed**: Doucouliagos1995 positive direction vs CraigPencavel1995 null. Do not claim cooperatives are unambiguously more productive.
5. **Cuba** — high life expectancy/HDI at low income is real and notable, but US has marginally *lower* infant mortality, and Cuba scores 9/100 on liberty. Report the bundle, not a cherry.
6. **Exact decimals** (V-Dem LDI, Fraser Nordic, OECD Gini per-country vintage) — **RESOLVED**: re-queried and verified from primary sources (V-Dem Dataset v16, 2025 data; Fraser EFW 2025; OECD IDD Dec 2025 update). Exact values now in the rows above and cited in the manuscript. The Fraser re-query corrected an earlier characterisation: on 2023 data the US ranks *above* the Nordics on Fraser (the reverse of Heritage).
7. **CO₂** — EDGAR 2023 used consistently; territorial basis noted; consumption-based caveat stated where Nordic figures are invoked.
