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.
