### Purpose Fix the intermittent `RayShuffleTest.test_primary_key_group_writer_does_not_depend_on_fusion` failure. Ray group-by shuffle does not preserve source row order within a group, but the test assumed the last source row (`0799`) must win even though the table has no `sequence.field`. ### Changes - Keep the test focused on its intended contract: one writer and one deduplicated row for the bucket. - Verify that the surviving row is one of the valid input rows instead of assuming shuffle order. - Document that deterministic duplicate-key precedence requires `sequence.field` with a source version and tie-breaker. ### Tests - `python -m pytest pypaimon/tests/ray_repartition_test.py::RayShuffleTest::test_primary_key_group_writer_does_not_depend_on_fusion -q` - `flake8 --config=paimon-python/dev/cfg.ini paimon-python/pypaimon/tests/ray_repartition_test.py` - `git diff --check` -- This is an automated message from the Apache Git Service.
