Recover::askRecover soft-set -wcdate, -mnemonic and -newwallet before every check had passed. SoftSetArg never overwrites a value, so when a check sent the user back to the dialog, the failed attempt's values stuck. A retry with an earlier wallet creation date kept the first date, so the restore scan could start too late and miss transactions, and each retry moved the date shown in the dialog a day earlier. Create new, then "Passphrases don't match", then Recover left -newwallet=1, so the restored wallet was never scanned. A valid seed with mismatched passphrases, then Create new, built the "new" wallet from that seed without scanning it. Run every check first and set the args in one place afterwards. Compute the scan date (one day before the picked date) straight into -wcdate instead of writing it back to the date field. -wcdate also stayed set for the rest of the session, so every later ScanForWalletTransactions (importaddress, importpubkey, importmulti, the BIP47 rescan) started at the restore date instead of its own start block. Clear it in CreateWalletFromFile after the initial scan. Tests: add WalletUiTests::recoveryRetryUsesFinalInput, which fails on the old askRecover whether the failed attempt creates or recovers.

Clear -newwallet after the initial wallet scan.
ScanForWalletTransactions returns before scanning when GetBoolArg("-newwallet", false) is true. CreateWalletFromFile leaves this flag set after the initial scan, so later rescans in the same session can be skipped.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Valid issue, but it's handled in #2011, which clears -newwallet (and -rescan) at this same spot after the startup scan. This PR keeps to -wcdate and the dialog checks so the two PRs don't overlap.

@reubenyap Thanks for clarifying the scope. The -newwallet and -rescan cleanup belongs to #2011. No duplicate change is needed in #2015.
The underlying finding is valid, so I am not marking it as fixed or invalid here.

Summary
After a failed attempt in the Qt "Create or Recover Wallet" dialog, a wallet restore could rescan from the wrong block, or not rescan at all.
Recover::askRecoversoft-set-wcdate,-mnemonicand-newwalletbefore every check had passed, andSoftSetArgnever overwrites a value. So when a check sent the user back to the dialog, the failed attempt's values stuck:-newwallet=1.ScanForWalletTransactionsthen returned early, so the restored wallet was never scanned and showed an empty balance.-mnemonic. The "new" wallet was built from that seed and never scanned.askRecovernow runs every check first and sets the args in one place afterwards. The scan date (one day before the picked date) goes straight into-wcdateand is no longer written back into the date field.-wcdatealso stayed set for the rest of the session. Every laterScanForWalletTransactionscall (importaddress, importpubkey, importmulti, the BIP47 rescan) therefore started at the restore date instead of its own start block.CreateWalletFromFilenow clears it after the initial scan.Related: #2011 does the same for
-newwalletand-rescan. The two PRs change different args. They touch neighbouring lines inCreateWalletFromFilebut merge cleanly in either order.Test plan
WalletUiTests::recoveryRetryUsesFinalInputdrives the dialog through a failed attempt (either creating a wallet or recovering from a later date), then a recover from an earlier date. It passes with the fix and fails on the old code:-newwalletstays set, and-wcdateis14-06-2021instead of09-03-2020.-mnemonicand-wcdate=01-06-2020, mine 250 blocks dated 2020-01-01 and 20 dated 2021-06-01, then runimportaddress <script> "" true. Before the fix it logsRescanning last 270 blocks (from block 51); after,(from block 0).ctest: everything passes exceptWalletUiTests::themeTintColors. That test fails the same way on master in this environment (swatch palette#efefefinstead of#fbeef0).🤖 Generated with Claude Code
