Key-figure check: median price diverges 29.3% from the nearest retained anchor (prior refresh cycle) — beyond the 12.5% tolerance; an automated validation case is open and the value publishes pending its verdict. Research outlier held out — this pass returned a median of $325,000 (29.3% off the retained reading), contradicting every independent anchor; the prior reading stands pending corroboration. Validation: the flagged $325,000 (-29.3% vs the prior refresh cycle) could not be independently corroborated and was reverted to the prior cycle value pending review; the case is under review in the Command Center.
