The preserved report, notebook, and course CSV are historical artifacts for 2025FA_IMEN5300_HOMEWORK03. The report and notebook are owner coursework; the CSV is professor/course-provided material with unresolved upstream provenance.
COLAB_0006 is an exact additional copy of the organized notebook and was not copied. It does not provide an independent result or an additional authorship basis.
The Module 6.65 repair plan and Module 6.75C verdict identify required statistical corrections and publication controls. They are audit evidence, not proof of a live randomized experiment.
The current public implementation is an expanded rebuild derived from graduate coursework and supporting experiments. Historical source files are preserved separately and are not represented as the public implementation. The rebuild uses synthetic data and does not imply production deployment or historical randomization without evidence.
