All pilot runs evaluated before the fix are re-evaluated with the same oracles; original receipts are kept in runs/pilot/\textless{}run\textgreater{}/evaluation\_receipt\_pre-A00 \textit{Rationale:} Pilot diagnosis: F4-dev-01 failed in all four arms with a spurious fabrication violation although every required criterion passed. Harness defect, not an oracle change. \\18A-003 & 2026-10-30T04:02 & 06 & before\ confirmatory\ results & Preregistration frozen as v1.0 (adds §10 pilot-informed decisions: confirmatory design 24 tasks $\times$ 4 arms $\times$ 3 repeats = 288 runs, seed 301); freeze manifest protocol/freeze\_manifest\_conf.json records SHA-256 of all 24 confirmatory bundles and oracles, arm texts, gate, launcher, scheduler, evaluator, configs and analysis scripts; tasks/registry.csv stamped frozen\_utc. \textit{Rationale:} Scale decision per §6 of the preregistration using measured pilot costs; no hypothesis, endpoint or analysis rule changed. \\19\bottomrule20\end{longtable}21
