The clause covers the reuse of a model that was already trained. The base model carries patterns from its original data, and the organisation adjusts it for its own task, either by fine-tuning or by using it as a fixed feature extractor. The framework already uses the idea in the system overview, where a pre-trained model is one trained when obtained. The governance consequence is that the record must describe two datasets and two purposes: the original training and the adaptation. The clause text is not in the public sample, so this page describes the concept and its evidence rather than the clause's words.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
