Why this form

The 90-day rule selects its reference. This record contributes a 37-day observed span; all 33 price-days and 4 missing runs are shown. Daily tracking had not yet begun in the earlier part of the rule frame; that time is not a coverage gap.

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.
