The Moon is flat.

Contradicted: P is the physical-shape claim that the Moon is flat. The search assessment addresses P directly and reports that NASA's Earth's Moon page describes the Moon as a three-dimensional differentiated body with a crust, mantle, and core, a cratered surface, and phases caused by viewing a half-sunlit Moon; that evidence strongly contradicts the claim that the Moon is flat. The fact-check assessment found no published fact-check results, so it supplies no independent corroboration or disagreement; its not-checked result is an absence-of-data limitation, not evidence for flatness. Because the search evidence is strong but some cited pages or snippets are unavailable or limited, the combined judgment is contradicted with high but not absolute confidence.

Confidence in this judgment: 95%

No published fact-check ratings or independent fact-check corroboration were supplied; the empty fact-check result means there is no fact-check agreement or disagreement to evaluate.

No retrieved document explicitly states that the Moon is spherical or spheroidal; the contradiction rests on the NASA assessment's description of a three-dimensional Moon and related features rather than an explicit shape statement.

The Wikipedia and Britannica pages were unavailable, so their snippets cannot be treated as reviewed article bodies.

The Moon Trek document contains only a title and provides little substantive evidence.

Further direct authoritative evidence explicitly describing lunar shape, or direct observational or geodetic evidence, would strengthen the judgment; credible contrary evidence about the Moon's physical shape would change it.
