VbzCart/docs/tables/stk lines

About

• Purpose: listing of what is now and what used to be in stock
• Refers to: Template:Vbzcart/table, Template:Vbzcart/table
• Notes: In early versions of VbzCart, this table was partly used as a sort of klugey stock-log. If a row containing qty>1 had less than qty removed from it, a new row was "split off" from the existing row and then the WhenRemoved timestamp was set, rather than setting qty to 0.
• Fields:
  • WhenRemoved: DEPRECATED. Keep setting it properly until it is removed completely, but don't use it.
    • There are currently still a lot of records where WhenRemoved is set but Qty is > 0, so until that remediation has been done, we have to keep referring to WhenRemoved. For now, make sure that Qty is set to 0 whenever all pieces have been removed from a record.
• Future: For all existing data where WhenRemoved is set and Qty>0, create stock log entries showing the removal and set Qty to 0. Finally, remove the WhenRemoved field altogether. Code which uses WhenRemoved as a flag should check the Qty field instead ("WhenRemoved IS NULL" -> "Qty > 0", "WhenRemoved IS NOT NULL" -> "Qty == 0").
