Price record

This is the independent record for the Home Depot listing above. It does not borrow prices, claims, or observations from another retailer.

Evidence instrument · full point-by-point record

Offered price vs. their claimed ‘was’

Home Depot · Aug 21 2026–Sep 23 2026

No observations · 5 separate runs; dates in the point ledger.

Why this form

The complete relevant record is already in this pane; a second map would repeat it.

Every line uses reduced price-days for one exact retailer offer. Both series share the coverage mask; intraday and Class B facts remain detached marks. The receipt ledger below is the complete text alternative.

Price history, changes, and missing observations — 12 entries

Point ledger · stable row IDs

Price history, changes, and missing observations

12 entries · change points, gaps, and dated facts

Complete dated text alternative to the price chart. A gap records missing knowledge; it never records an offer change.
