Can an AI Assistant Really Forget? Auditable Deletion from Addressable Memory

Excerpt

arXiv:2607.27539v3 Announce Type: replace-cross Abstract: Certifying that a deletion did what it declared does not certify that the record left no trace: a small distance to the implementation's own reference does not imply a small distance to the state that never stored the record. This paper installs a deletion interface into a pretrained language model and measures both distances. We retrofit a support-vector memory gate into the global attention layers of a frozen Gemma 3 without changing a
