Why this form

Claim absence changes only the retailer-claim series; offered observations remain continuous.

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 — 2 entries

Point ledger · stable row IDs

Price history, changes, and missing observations

2 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.
