CUSTOMVANHow it works

History keeps its original date

Observed amounts.
Visible limits.

Same exact variant,merchant,native currency,condition and package basis stay separate. No days are backfilled,overwritten or interpreted as missing stock. Current pilot amounts have one observation date: no price trend or discount is established.

Source dates never move by themselves
Source dates never move by themselves
  1. Retained record
  2. Observed amount
  3. No invented trend

Original immutable-history explanation; one dated cohort does not establish a trend.

Merchant stock claims are evidence snapshots,not guaranteed live availability. Saved builds keep their own snapshots beside current facts.
