Continuity with boundaries
Relationship memory should help a system remember stable preferences, prior commitments, and the meaning of shared events. It should not retain everything by default or silently transform uncertain interpretations into permanent facts.
Proposed memory layers
We distinguish session state, user-approved preferences, episodic summaries, and revisable relationship hypotheses. Every layer needs provenance, scope, a way to correct it, and a way to delete it.
Evidence boundary
Prior work shows that stored experiences, reflection, and retrieval can support coherent agent behavior. Our privacy-preserving relationship model is a separate hypothesis and has not yet been validated through longitudinal user research.
