The Comedy's Italian is public vernacular practice matching De vulgari's theory, stored as one language-access path
The Comedy's Italian is public vernacular practice matching De vulgari's theory. 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 Comedy's Italian is public vernacular practice matching De vulgari's theory. Dante Alighieri's documented role is: He wrote the poem in Italian. Later print is carrier. One language-choice, not a hundred dialect-Facts.
Context
De vulgari is the theory row. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
That reading is an impact-path choice, not a property stored on the Fact itself.
Why it matters
The welfare reading on this path is improving.
Naming Dante Alighieri does not delete co-authors, institutions, or later transmitters. The lag from 1320-09-01 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.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
