• 2026-10-30 P0: read TASK.md, wrote contract.
• 2026-10-30 P1: audited all inputs (see data_audit.md). Decision: E4 needs a counterfactual/baseline level of the fatal hospitalisation rate per 100,000, which the extract does not print -> not harmonisable.
• 2026-10-30 P2: baseline_naive keys added (printed values at face value).
• 2026-10-30 P3: analysis.py written; 4 harmonised, E4 not harmonisable.
• 2026-10-30 P4: reproducibility IDENTICAL; checks.md written; gate run 1 (20261030T051145.833635Z) failed only on P5 deliverables (report/claims not yet written).
• 2026-10-30 P5: report.md and claims.json written; gate re-run.
• 2026-10-30 P5: final gate receipt 20261030T051220.044021Z passed (24/24). All phases passed.
