Complete original files retain BSD3license and attribution in official/athena-LICENSE.txt. The original source/initial-condition definitions are reference material; the detached replay does not build or run Athena or its3Dregression.

New independent Python/controlled numerical outputs: LICENSE-code.txt. No protected app/Engine or third-party tool binary is included.

Truelove et al.1997, ApJL489,L179–L183, DOI10.1086/310975, was not obtained as a complete paper. ADS403and publisher HTML challenge are retained as failed source attempts. The numerical guard in this prototype is a declared8-cell thermal-Jeans stopping indicator, coupled with actual spatial/time comparisons, not a claimed reproduction or universal certification of the original paper.

The root research source-members.json/download-budget.json retain fixed original bodies, exact bytes/SHA, versions, source URLs and reading/permission scope. Original paper PDFs, metadata HTML and page renderings remain private research caches and are deliberately absent from this ZIP. No simulation data library, observed molecular-cloud cube, real stellar IMF inference, images or large tool installation is included.
