CORRECTIONS
Errors are corrected by disclosure, not by rewriting the past.
Methodology §7 requires a dated notice on the affected print and in the next print. If a published value is wrong, the original remains visible and struck through.

Source vintage and observation months
This receipt uses the September 28, 2026 source retrieval, with August 2026 ZHVI and AHETPI observations. October names the publication month, not the data month. All historical rows and the August 2025 year-ago comparison are recomputed from this vintage; June and July receipts retain their published values. Revisions to source history can change comparisons between receipts. The CPI counterfactual holds the latest annual observation available in this committed snapshot (2024) flat thereafter; it is a reference path, not observed 2025 or 2026 inflation.
Affected print: 2026-10. Pattern: original value corrected value.

Source revision note
Zillow revised its published ZHVI bottom-tier history in the 2026-07-13 retrieval, so every historical row in this print is recomputed from the new vintage and sits about 1% above the June 2026 print (for example, 2000 Q1 is 2.09 work-years here versus 2.07 in June). The June print is unchanged as published; each print reports its own source vintage.
Affected print: 2026-07. Pattern: original value corrected value.
