Flag 4 (fail) combines two independent exclusions: this variable’s own gross-range and spike tests, and the whole-cast soak / on-deck trim, which flags the same pre-descent and post-recovery scans on every variable. A variable can therefore show flagged samples that its own thresholds did not raise.
