The Relation Registry.
What the system will seal, and what it will not.
A relation is the classification of what a declaration represents. CTinFold seals a fixed set of allowed relations and refuses a short list of forbidden ones. The refusal is not a moral judgement. It is a boundary of proof. The system seals what it can prove, and declines what it cannot.
Every declaration carries a relation, the economic meaning of the event: a sale, a lease, a deposit, a settlement. CTinFold recognizes twenty-nine allowed relations, eighteen already established and eleven newly added, several mapped to recognized Islamic finance standards. It also names six forbidden relations. The forbidden set exists for one reason. These relations cannot be mapped to a deterministic proof chain without importing assumptions that belong to scholarly or regulatory authority, not to a sealing system. CTinFold does not adjudicate what is permitted in law or in faith. It seals what is declared, when what is declared can be proven.
A relation is the meaning of a declaration.
When a partner declares an event, they are not only stating an amount and a counterparty. They are stating what kind of event it is. That classification is the relation, and it determines how the decision engine reads the declaration and what a valid outcome looks like. A sale is not a loan. A deposit is not a service fee. The registry of relations is the vocabulary the system will accept.
The established relations. Eighteen.
These relations were part of CTinFold from the outset. Four of them map to recognized Islamic finance standards under AAOIFI.
The new relations. Eleven, in four behaviours.
The eleven additions are grouped by how they behave over time. Some are a single event where money moves once and the matter is done. Some open a registry of payments that run to zero. One is declared once but triggers later. Two operate together as a deposit and its withdrawal.
The deposit pair is described in full in Paper No. 03, The Deposit Registry.
The forbidden relations. Six.
Six relations are declined. They are unchanged, and they will not be sealed.
Why these are forbidden. CTinFold does not adjudicate what is permitted or forbidden in law or in faith. The forbidden list exists because these relations cannot be mapped to a deterministic proof chain without embedding assumptions that belong to scholarly or regulatory authority, not to the system. To seal them, CTinFold would have to decide questions it has no standing to decide. So it declines. The boundary is one of proof, not of judgement.
