	DiscoverFunc func() (string, error)

	// BackupFunc performs the actual backup, writing issue data to the
	// provided writer and returning the number of issues written. In
	// production this wraps svc.Backup; tests provide a stub. The
	// writer is a gzip.Writer that the caller manages — BackupFunc
	// should not close it.

	Output string

	// JSON enables machine-readable JSON output.
	JSON bool

	// WriteTo receives the command's human-readable or JSON output.
	WriteTo io.Writer

	// Prefix is the database's issue ID prefix (e.g., "NP"). When
	// non-empty and the default filename is used (Output is empty or
	// Output is a directory), the prefix is included in the filename:
	// backup-<prefix>.<timestamp>.jsonl.gz.
	Prefix string

	// SuccessIcon returns a colored or plain success indicator for
	// human-readable output. When nil, a default "[ok]" is used.
