Not every imaging run covers a full rectangular grid. When a Keyence BZ scan skips positions on the stage grid — imaging only the wells or regions you care about — the resulting montage is sparse or non-rectangular, and previously those scans were flattened into a single-row layout that didn't reflect what was actually captured.
The agent now reads physical image dimensions and tile coordinates directly from the scan metadata, so each tile is stitched into its true position on the montage. Sparse layouts, rectangular layouts, and single-row scans all render with the correct geometry, and tile positions travel with the imaging metadata so downstream tools can work with the real stage layout.
