credential-store --file fails in WinRM on Windows (path escaping, no helper binary resolution in non-interactive shell). Switch to http.extraHeader: git -c credential.helper= -c 'http.extraHeader=Authorization: Basic <b64>' clone ... Advantages: - No credential helper binary needed - No temp file (no cleanup required) - Token never in URL, command display, or Write-Host output - Works in WinRM non-interactive sessions (no TTY dependency) - GCM still cleared by credential.helper= prefix §1.5 compliant: Base64 is in git process argv (not logged by Write-Host).
