## Returns

[PurchasePack](/types/PurchasePack/) `[PurchasePack!]!` — A purchase pack — a purchasing/handling packaging definition ON a variant (case of 24, pallet of 480): NOT a UoM conversion (the inventory ledger is ALWAYS in the variant stock UoM — reaffirmed); a pack is packaging metadata + a line-ENTRY breakdown step (PO/Receipt lines entered in packs resolve to stock units at entry: packQuantity x unitsPerPack). Parent = the VARIANT (0..N packs per variant). unitsPerPack is IMMUTABLE at birth, which keeps every stored document line reconstructible forever. The code is a dup-gated LABEL (trim+case-fold vs LIVE siblings on the same variant, naming the holder — lean 1: no UNIQ marker). Live packs block the parent Variant doom (the children law); live OrgVendorItems naming a pack block ITS doom; deactivate stays FREE everywhere (an inactive pack refuses NEW line entry while its unitsPerPack keeps denominating stored terms).
