What the sources establish

Britannica and the later journal independently describe padrões as a Portuguese claim-ritual on Gama’s voyage. Official: Britannica — Vasco da Gama, padrões (https://www.britannica.com/biography/Vasco-da-Gama (opens in a new tab); Encyclopaedia Britannica). Independent: Journal of the First Voyage — pillars English (https://www.gutenberg.org/ebooks/22599 (opens in a new tab); Project Gutenberg). The two URLs are different pages. Where the carrier is a later edition or a received narrative, that limit is stated rather than upgraded to an autograph.

Independent carrier: Journal of the First Voyage — pillars English (https://www.gutenberg.org/ebooks/22599 (opens in a new tab); Project Gutenberg).

Established: padrões as a first-voyage claim-ritual. Not established: that every later museum pillar is his 1498 cut. Established: a sourced public record of The first voyage plants padrões as stone claim-markers on African shores under 1498-01-20.

Shared responsibility is part of The first voyage plants padrões as stone claim-markers on African shores. Naming Vasco da Gama does not delete co-authors, institutions, or later transmitters. The lag from 1498-01-20 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.

That reading is an impact-path choice, not a property stored on the Fact itself.
