definitive
This term conveys a sense of absolute finality and authority. When describing a decision or a ruling, it suggests that the matter is closed and no further appeals or changes are possible. It carries a weight of permanence that distinguishes it from a mere decision. In the context of a work or a record, it implies a gold standard of accuracy and comprehensiveness. A definitive biography is not just one of many, but the one that renders others obsolete by being the most complete and reliable source available.
