Derived memory

The definition

Anything a system built from a stored item: a summary, a reflection, a plan, a cached tool result, a learned skill, an embedding, a copy in a peer agent. Deleting the item leaves derived memory in place unless the system traces and repairs it; 2026 research shows this is where deleted facts survive and return.

The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.
