It lets viewers understand the vessel's scale and shape before opening the hull to inspect the systems within it. ## What Forge has demonstrated The envelope follows the best-documented primary survey state while later observations remain available as separate evidence layers. This keeps the visual assembly coherent without losing the history of how the vessel was recorded. ## What a partner could unlock Offset tables, higher-resolution surveys, shell records, and current-condition data could turn the visual envelope into a more exact hull definition and support future hydrostatic and engineering evaluation.
