The 1604 supernova is used by Galileo as a public anti-immutable-heavens heading
Galileo Galilei's documented role is: He lectured that a new star argued against immutable orbs. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.
Read the full account
The star is nature's. The lectures are his. Galileo Galilei's documented role is: He lectured that a new star argued against immutable orbs. The sky event is nature's; the lectures are his.
Context
Kepler also wrote the star. Sharing the sky with that independent file is required. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
If a number is not in the two records named above, it is not supplied here.
Why it matters
Public lectures on a new star are an education path. The welfare reading on this path is improving.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

That reading is an impact-path choice, not a property stored on the Fact itself.
Confidence is stated on the impact path, not hidden in adjectives.
Naming Galileo Galilei does not delete co-authors, institutions, or later transmitters. The lag from 1604-10-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
