This scientific packet does not redistribute NumPy, SciPy, Python, a web
Engine, third-party publications, paper images or observational archives.
NumPy 2.3.5 and SciPy 1.17.1 are separately installed dependencies for the
optional full model replay and remain under their upstream licenses. The
standard-library inspection requires neither package. requirements.txt lists
dependencies; it does not bundle their code or transfer their licenses.

The photon-counting allocation here is an independently authored adaptation,
not copied upstream code or a claim to reproduce a published radiative-
transfer implementation. The integrating-factor and geometric references
are original standalone implementations. Original scientific sources:

Madau, Haardt & Rees (1999), astro-ph/9809058v1, global ionized-volume budget.
Hui & Gnedin (1997), astro-ph/9612232v1, Appendix A recombination fit.
Roy Choudhury & Paranjape (2018), arXiv:1807.00836v2, photon-conserving allocation.
Furlanetto, Oh & Briggs (2006), astro-ph/0608032v2, ideal 21 cm line mapping.
NIST/CODATA, declared SI constants; atomic values are frozen in each input.

Only the specified model relations and source sections were used. No full
observational pipeline, posterior or source-paper figure is reproduced by
these scripts. Public evidence files are explicitly labelled projections of
receipts whose full originals remain in the private scientific archive.
