  "summary": "This pull request checks wallet names using `util::TrimStringView` before empty-string validation in `CreateWallet`, `CreateFromDump`, and `WalletTool::ExecuteWalletToolFunc`. Wallet creation and wallet-tool dump restoration are prevented from using names consisting entirely of whitespace, while existing wallets with such names can still be loaded.",

    "maflcko questioned the real-world benefit and motivation, cautioning against any risk of breaking existing wallet UX.",

It addresses an edge case where users could create wallets named solely with spaces, leading to confusing directory listings that look blank. The change has minor usability value and fixes an oversight in the existing empty-name check without affecting existing wallet loading. Concept feedback is generally supportive of disallowing space-only names upon creation, though reviewers question whether the benefit is worth changing validation rules."
