Starting with planner stability, three linked commits by Richard Guo address outer joins and placeholder variables. Commit 3138f24 stops the planner from removing an intermediate result step when a nested placeholder still depends on it, preventing a lateral self-dependency and assertion failure. Commit 7787aec…
