Explanation
~るまでだ is used to highlight that a situation or amount is limited to a certain point or extent. It emphasizes that there is nothing more beyond that point; the matter ends at that boundary. It can convey a sense of resignation or inevitability, depending on context. The phrase often appears after a verb in its dictionary form to mark the limit of what is true or possible, or after a noun/adjective to indicate that the state ends at that limit.
