//! Cloud mining recovery — recover mined webcash and transfer to main wallet.

//! is recovered independently (deterministic secret scan), then its balance
//! is transferred to the main wallet via a secret webcash string.

/// 1. Open the labeled webcash wallet (caller provides the opener)
/// 2. Run `recover_from_wallet(50)` — deterministic secret scan

///
/// The `open_wallet` closure takes a label and returns (labeled_wallet, main_wallet).
/// This avoids pulling CLI-specific functions into the library.
