The logging statements were updated to remove the string values because the variables were moved on lines 1298-1299. However, these log statements are now less informative. Consider either: 1) keeping the original code without std::move() for these variables since the performance gain is minimal for short-lived local variables, or 2) logging the values before the move operations.

After moving stashAccountId into the set_RFCProperty function at line 1345, the variable is in a valid but unspecified state. The assignment at line 1356 (_accountId = stashAccountId) will assign this unspecified value to _accountId, which is incorrect. The std::move should be removed from line 1345, or the assignment at line 1356 should use the value before it was moved.

The TOCTOU fix is correct in removing the race condition between stat() and remove(). However, silently ignoring all remove() failures (via void cast) may hide legitimate errors like permission issues. Consider logging at DEBUG level if remove() fails, checking errno to distinguish between "file not found" (expected race condition) and other errors like EACCES (permission denied).

Using std::move on a local variable (value) to assign to a member variable (_valid_accountId) prevents copy elision and doesn't provide any benefit here since the local variable is going out of scope anyway. Additionally, if value is moved and later accessed in the logging or comparisons that follow, it would be in an undefined state. In this case, the move appears safe since value is not used after the assignment, but it's unnecessary and could be confusing. Consider removing std::move and letting the compiler optimize the assignment.

An unnecessary blank line was added at the beginning of the file. This appears to be unintentional and should be removed to maintain code consistency.
