Transferable evidence reconstruction (TER) is introduced: a Ridge regressor fits evidence from representations in one group and predicts it in an identity-disjoint group without refitting, and uses meaningful signal properties to supervise not only what a representation preserves, but how reliably it can be read across...

In-situ representation refinement is developed: support labels guide changes to the episode's representations, improving the information available to later queries, in a competitive, memory-efficient model.
