NASA · Stored JPEG is a resized crop of NASA's S66-32139 asset (stored 2048x1919 SHA-256 2a4915588b5da033b5bd9df24cd139d15eaf602ac32451c5f18950c50f2b23bf; authoritative 2371x3000 SHA-256 e4fc9995c36630a9a59cb9066ab19fdfa0ef5901e62f693134e4bc03567e80c6). A crop-aligned comparison against the authoritative source (source crop y=778, height 2222, resized to the stored dimensions) yielded MAE 13.41, RMSE 15.19, and Pearson correlation 0.99138, conclusively identifying the stored derivative.
