What Commons does
Users should be able to upload an image, image pair, or sequence; let the system attempt morphology-family identification; inspect the segmentation and SVG trace; export metrics and routing records; and compare the result against reference families.
Evidence package doctrine
Every claim must travel with its trace. That means the evidence package should preserve the raw image copy or hash, normalized image, binary mask, overlay, SVG trace, metrics tables, routing JSON, and a readable report.
Cross-domain comparison
The interesting question is not whether two forms “look kind of alike.” The question is whether the descriptor profile, trace topology, and process hypothesis survive a disciplined comparison with explicit limits.
