Summary	0012149: Deleting a transaction from its page ends on "Internal core error" (7052 transaction not found): the list row asks for the transaction just deleted (patch attached)
Description	Deleting a completed payment works, and the user is then shown an error for it. Steps (no fault injected; first seen in fuzz campaign c2h-29, episode 39, then reproduced by a scenario): 1. Pay an order. Open the payment from "Recent transactions". 2. Scroll down, "Delete from history", confirm (delete-confirmation.jpg). 3. The page closes, and "Internal core error -- 7052 -- transaction txn:payment:... not found" comes up (delete-shows-internal-core-error.jpg). From the app log: 27.965 deleteTransaction{txn:payment:8K60...} 27.982 handleStateTransition: Deleted: txn:payment:8K60... 27.991 switching from 22 to 11 BalancesListView.swift:72 27.993 getTransactionById{txn:payment:8K60..., includeContractTerms:true} 27.994 ... error: { "code": 7052, "hint": "transaction ... not found" } Cause. Back on Balances the row of the deleted payment is still on screen for a moment, until the list has reloaded. TransactionRowView.viewDidLoad() fetches the full transaction for payments to get the merchant's logo: if let fullTx = try? await model.getTransactionById(txId, includeContractTerms: true) { The `try?` shows the failure is meant to be ignored, but sendRequest() reports every error to the user unless the caller passes viewHandles: true. (A log line in TransactionSummaryList.loadTransaction() confirmed the request does not come from the detail page.) Patch (delete-transaction-7052.diff): pass viewHandles: true for this cosmetic lookup. Built and run: the same scenario now returns to Balances with no error. The same pattern -- `try?` around a request that still raises the error sheet -- is used in other places, so other "harmless" lookups can surface as Internal core error in the same way.
