Observation
The source still contains a high-contrast dark round point near the reticle and a broader tonal boundary in the surrounding image field. The submitted thermal-style view makes the boundary easier to perceive as a rim-like arc or edge band, but the source does not resolve a three-dimensional hull, material surface, or measured thickness. The most useful source-backed phrasing is narrow: FBI Photo A003 contains a rim-like tonal boundary around the target-region view. The feature can support morphology review, but it does not prove that the rim is a physical craft edge.
