  "scope": "All millimeter coordinates inherit the provisional152mm engine stud span and interpreted photo frame. Sparse surface points, manual feature/region interpretation and shared cameras do not establish metric accuracy, silhouette extrema or fitted dimensions. The selected front/back planes, upper seam,15mm backplate depth, corner radii and lid sections are rounded construction choices. The existing100mm X envelope and unobserved lower/outboard datums stay as estimates. The independent250x120x30mm filter comparison is retained; it is not resized to fit this case. Inlet geometry follows the revised rear wall using the previous estimated8mm port inset; its shape and onward circuit remain unverified. No compatible element, seal, latch engagement, fitted clearance, cold-air circuit, operating flow or verified removal path is established.",
