Supported formats: .gtl, .gts, .gto, .gbo, .gbl, .gbs, .txt
1nm Precision
All coordinate transformations and patches are scaled and calculated using strict 1nm integer math to prevent floating point drift.
Round-trip Integrity
Every single export undergoes semantic subsequence block validation to guarantee that 0% of the original physical shapes were mutated.
Visual Diff Mode
Toggle Difference mode in the 3-panel workspace to immediately highlight injected patches in stark cyan against the original traces.
