W107: Dispose inventory

Records the permanent removal of finished goods. Triggered from the Finished Goods Inventory page, "Dispose". Mirrors the materials equivalent (W100).

Steps

1. Validate the SKU and location. Confirm both exist.

2. Write the DISPOSE ledger entry. Call FinishedGoodsInventory.recordDisposal({ skuId, locationId, quantity, eventDate, notes }). quantity is positive (per the L1 invariant); DISPOSE encodes outflow direction. ref is null.

Returns

The ledger entry.

Business rules

• Disposal is distinct from adjustment. The DISPOSE event type lets reporting separate scrap and loss from positive corrections.
• No stock guard. The workflow does not block disposals that would take on-hand below zero.

Errors

• NotFoundError. The SKU or location was not found.
