  Entity-relationship graph derived from OpenAPI component schema id-reference
  fields (integer/uuid foreign keys). In Campfire's model, "customer" on nearly
  every object is the tenant organization (belongs_to customer / multi-tenant
  scoping), while "vendor" records represent external payees/customers. All
  amounts reference a "currency" and most records reference a "ChartEntity"
  (entity) — the legal entity within the org. Relationships listed are those the
  schema field names make explicit; not exhaustive.
