1\section{Reproducibility and release}2\label{sec:reproducibility}34The repository \texttt{wp41\_uqo} contains the package \texttt{chronos\_x} (data connector, calendar, quality5checks, corporate actions, grids and windows; models; training; scoring and inference; baselines), the numbered6scripts that produced every artifact cited here, the configurations that freeze the protocol7(\texttt{configs/pilot}, \texttt{main}, \texttt{ablations}, \texttt{baselines}, \texttt{final}), the test suite8(calendar and timestamp conventions, grid construction on synthetic bars, leakage gate with a quarantined9future-feature fixture, model shapes and parameter counts, numerical checks of the Student-$t$ density and CRPS10against Monte Carlo, copula sampling and likelihood, live API contract tests), the universe manifest with its hash,11the provenance logs of every API call, the phase reports, and the LaTeX source whose tables and macros are12generated from the saved results. A synthetic cache in the exact FinData schema lets anyone run the entire pipeline13without a license (\texttt{configs/synthetic\_smoke.yaml}). Raw bars, grids and per-origin returns never leave the14compute node; the released artifacts are code, aggregate scores and figures of scores. The FinData dataset versions15used are \num{17375} (stocks) and \num{5162} (ETFs); the API audit and the coverage audit are saved with the16results. Seeds, checkpoints and the exact commands are listed in \texttt{docs/REPRODUCIBILITY.md}.17
