Key-figure check: median price diverges 16.6% from the nearest retained anchor (published ten-year series (2024)) — 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 $790,000 (16.6% off the retained reading), contradicting every independent anchor; the prior reading stands pending corroboration. Validation: the flagged $790,000 (-16.6% vs the published ten-year series (2024)) failed independent re-validation and was reverted to the prior cycle value; the case is under review in the Command Center.
