#758 removed the render-time float-dtype guard on the assumption that spatialdata always rejects float labels at the model boundary. That only holds on spatialdata >=0.8; the library still supports spatialdata >=0.3, where float labels parse fine and would again crash deep in skimage with a cryptic TypeError (#606). Restore the guard so the clear error holds across the whole supported range. - render.py: re-add the float-dtype ValueError guard. - test_render_labels.py: re-add test_render_labels_rejects_float_dtype in a version-agnostic form (assert an "integer dtype" error is raised at whichever layer enforces it: spatialdata on >=0.8, our guard on <0.8). - test_render_shapes.py: sort queried shapes before render so the overlap draw order (and the baseline) is stable across spatialdata's query-order change in 0.8; regenerate the baseline accordingly. The measure_obs float coverage stays as the version-independent _stream_label_centroid_stats unit test added in #758.

#758 (merged) removed
_render_labels' float-dtype guard, assuming spatialdata always rejects float labels at the model boundary. That only holds on spatialdata >= 0.8. The library still declaresspatialdata >= 0.3, and on spatialdata < 0.8Labels2DModel.parseaccepts float labels — so with the guard gone,render_labelsagain crashes deep in skimage with a crypticTypeError(the #606 regression). This PR corrects that.Changes
ValueErrorguard (safety net for spatialdata < 0.8; >= 0.8 rejects earlier at the model boundary).test_render_labels_rejects_float_dtype, now version-agnostic: asserts an"integer dtype"error at whichever layer enforces it (spatialdata on >= 0.8; our guard on < 0.8).sort_index()the queried shapes before rendering the random-shuffling test, so the overlapping circles' draw order (and baseline) is stable across spatialdata's 0.8 query-order change; baseline regenerated.measure_obsfloat coverage stays as the version-independent_stream_label_centroid_statsunit test added in #758.
