the.com/vindication

means The act of being proven right or justified, usually after someone doubted, accused, or dismissed you.

from From Latin vindicare, 'to claim, avenge, or liberate' — built from vim dicare, roughly 'to assert force or power.' In Roman law it meant formally laying claim to something, or defending a claim against a rival. That sense of legal self-defense curdled over time into something more personal: proving, publicly and satisfyingly, that you were right all along.
