Read the full account

Leonardo's experimental binder on the Last Supper began failing in reports from the next decades, including within living memory. Leonardo da Vinci's documented role is: He rejected buon fresco for an experimental binder. The image flaked; later restorers are not this choice.

Context

Buon fresco would have locked pigment in plaster. Sharing the failure with that technical choice is required. The setting of Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports is the public file around 1498-06-01. Contribution type is direct. Driver personal-data-protection is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

Why it matters

Worsening path from Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports on 1498-06-01. The welfare reading on this path is worsening.

Confidence is stated on the impact path, not hidden in adjectives. Technique is the instrument. Mixed effects of Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports are separate paths.

Established: a sourced public record of Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports under 1498-06-01 for Leonardo da Vinci. Established: a sourced public record of Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports under 1498-06-01.

Shared responsibility is part of Leonardo's experimental Last Supper technique begins to fail within his later lifetime observers' reports. Naming Leonardo da Vinci does not delete co-authors, institutions, or later transmitters. The lag from 1498-06-01 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.

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