-- Seed data: dt=20260507 in-window rows (kept) + dt=20260506 decoys (filtered by dt rule).
-- Coverage design (decoy + positive-example pattern):
--   * dt filter decoy:        2 rows at dt=20260506 with value 99/50 -> must be excluded.
--   * SUM aggregation:        AppGrp1/AppGrp2 have multiple tasks per group -> SUM != MAX/MIN/COUNT.
--   * GROUP BY dw_appgroup:  PlanA/ObsA/ProdA spans AppGrp1, AppGrp2, NULL -> dropping it merges rows.
--   * GROUP BY plan_product_name: PlanE vs PlanF share (ObsE,ProdE,AppGrp5) -> dropping plan merges them.
--   * GROUP BY obs_product_name:  ObsG vs ObsH share (PlanG,ProdG,AppGrp6) -> dropping obs merges them.
--   * GROUP BY product_name:      ProdI vs ProdJ share (PlanI,ObsI,AppGrp7) -> dropping product merges them.
--   * NULL boundary values in grouping fields (dw_appgroup=NULL, obs_product_name=NULL).
