Settlement Items Are Written in the Causing Transaction

Context

A retained outstanding effect must agree with the document change that created it.

Decision

Record document-caused settlement effects through a function that joins the caller’s existing transaction.

Alternatives Considered

Build the ledger entirely from source-document reads. Manual fees and reserves lack matching documents, and arrival timing needs retained facts.

Create effects from asynchronous document notifications. Delayed or failed handling would separate visible outstanding money from committed document effects.

Consequences

Eligible recording can refuse the document change when timing is unavailable. Transactions uses a replaceable port with an explicit Reconciliation contract. Future imports should reconcile effect identity rather than create a separate competing money ledger.
