- 2026-10-30 P0 passed: contract written.
- 2026-10-30 P1: audit done. Assembled file has errors (overlap uses old vintage; 2016-07 dropped and later values shifted one month; spurious 2026-10 row). Decision: compute only from the two vintage files; assembled file read for audit only. 2025-10 missing in 2026 vintage -> g_2025-10 missing, not imputed.
- 2026-10-30 Incident: state files were mistakenly first written to data/out/ (shell cwd error); moved to ./out/. Input CSV hashes re-verified unchanged.
- 2026-10-30 P1 passed (audit, exclusion ledger produced by script).
- 2026-10-30 P2 passed: baseline = mean_growth_12m_2001_2013 (task-named baseline key), plain unconditional mean.
- 2026-10-30 P3 passed: analysis.py written; feasibility "partial" because g_2025-10 not computable.
- 2026-10-30 P4 passed: deterministic re-run identical; 18 independent checks pass.
- 2026-10-30 P5 passed: report, claims, final phase statuses written. Task complete.
