The expensive part of AI output begins after the model finishes

DepthCarve begins with a free comparison because a user should see whether the model understood the scene before paying for a professional format. Range, direction, dimensions, and density remain explicit instead of disappearing behind a single Generate button. The system then exports a representation for another verified tool; it does not pretend to replace CAM, a slicer, a laser controller, or a compositor.

This boundary protects both the user and the product. A technically completed but aesthetically unsuitable estimate can be rejected at the free stage. A provider that fails after a paid job begins triggers an automatic, uniquely referenced credit refund. A file that enters physical production still requires the workshop's normal simulation, calibration, material test, and safety process.
