DiCara's Citra chapter footnote 20 (line 1437): "An interesting contention is that Maya built great cities in what is now Latin America, founded the Mayan culture, and created their calendar. The classic Indian astronomy textbook, Sūrya Siddhānta is said to be explained by the Sun god to Maya."
This is preserved with [SPECULATIVE — fringe Vedic-revisionist] flag in both the Tvashta-Vishvakarma-Maya page and the Citra enrichment. It is a standalone collision-stub (not a contradiction with another vault source) because the claim raises serious cross-cultural-archaeoastronomy questions while sitting on the fringe of Vedic-revisionist scholarship.
DiCara drops the Mayan-Maya claim into a footnote and moves on. It's startling enough to stop the reader mid-page. The mainstream-historical-archaeology position is the opposite: Mesoamerican Mayans developed independently in the Americas; no transoceanic-contact from South Asia; the Mayan calendar emerged from Mesoamerican astronomical-tradition; Sūrya Siddhānta is a 4th-5th-century-CE Indian text with no documented Mesoamerican connection. Two stories competing for the same set of cosmological-archaeological facts. One says the Vedic-architect built both. The other says they're independent traditions that happen to share some astronomical-iconography. Vault-handling preserves both — flags the DiCara claim as [SPECULATIVE — fringe Vedic-revisionist] and keeps the cosmological-narrative without endorsing the historical-empirical claim.
Three positions are available:
The vault-treatment is option 3 by default: preserve the claim with [SPECULATIVE — fringe Vedic-revisionist] flag so that the apparatus's own narrative is preserved without endorsing the historical-empirical-claim.
For option 1 (reject): mainstream-scholarship's independent-cultural-development consensus would need to remain unrebutted by any new empirical-archaeology.
For option 2 (accept): some new archaeoastronomical-evidence would need to surface demonstrating actual-historical-transoceanic-connection between South-Asian-and-Mesoamerican astronomical-traditions. The cross-cultural-astronomical-iconography convergences (Capricorn-Makara across multiple traditions, calendar-system-similarities) would need to be re-examined as evidence-of-contact rather than as independent-development.
For option 3 (cosmological-narrative without commitment): just preserve the apparatus's own narrative with appropriate flagging.
