Devin's Dreaming feature builds a memory graph across sessions

Cognition introduced Dreaming, saying Devin builds a memory graph of how users like to work across sessions and improves it at night. Cognition also says it is creating an open-source standard called Agent Memory Repo. A post sharing the announcement says the memory format supports graph relationships and updates with historical records, is backed by Git and Markdown, and can be used with agents beyond Devin.
