An AI assistant remembering last month’s arrangement can be helpful, until an old exception quietly becomes a new promise to a customer. Working memory is not an authoritative business record. Useful context can become outdated, incomplete, or valid only for one specific situation. Give retained context a source, scope, responsible owner, and review date. Keep the underlying record separate from the assistant’s recollection. Before making a new commitment, review expired or conflicting memories against current evidence. Start with a workflow that drafts before it acts. Test what happens when memory is wrong, and make forgetting part of the process. A remembered instruction should not become permanent authority. Original article explainer. AI-assisted conceptual illustration and neural narration; original synthesized music. Not a human recording or customer result.
