Struct LocationFacts 

pub struct LocationFacts {
    pub id: Uuid,
    pub usage: String,
    pub warehouse_id: Option<Uuid>,
    pub valuation_account_id: Option<Uuid>,
}

The location facts a move’s guards and valuation core need: usage (supplier/view/internal/ customer/inventory/production/transit — the routing + reservation rules key off it), and the warehouse a valuation bin resolves to. usage decodes as text like every other enum here.

Fields

id: Uuid

usage: String

warehouse_id: Option<Uuid>

valuation_account_id: Option<Uuid>

Per-location valuation-account override: when set, an inventory GL leg that touches this location resolves to it ahead of the caller-supplied (door-header / directive) account — the smallest-first override of the account-resolution chain. None = no override.
