Logistiki.BusinessEntities.BusinessEntityClosure (logistiki v0.1.0)

Closure table for the business entity hierarchy.

Each row records that ancestor is an ancestor of descendant at depth. A self-row has depth 0. The closure table is maintained by Logistiki.BusinessEntities on insert and move.

Fields

id — integer() — primary key (e.g. 1)
ancestor_id — integer() — the ancestor entity id (e.g. 1 for Acme Holdings)
descendant_id — integer() — the descendant entity id (e.g. 2 for Acme Trading Ltd)
depth — integer() — 0 for self, 1 for direct child, 2 for grandchild (e.g. 1)
inserted_at — DateTime.t() | nil — set on insert (no updated_at; e.g. ~U[2026-07-07 12:00:00Z])

Example

%Logistiki.BusinessEntities.BusinessEntityClosure{
  id: 1,
  ancestor_id: 1,    # Acme Holdings
  descendant_id: 2,  # Acme Trading Ltd
  depth: 1,
  inserted_at: ~U[2026-07-07 12:00:00Z]
}
