 * Every business that stands for the foreign-securities portfolio: the tenant's general
 * foreign-securities business, plus one business per traded security.
 *
 * A securities transaction's counterparty is the specific security once it is recognized, and
 * the general business only where none could be resolved — so anything keyed on "is this the
 * securities side" has to ask about the whole set, not just the general id.
 *
 * Both sources are request-cached (admin context per operation, security ids per provider), so
 * calling this per transaction is cheap.
