Engram shows how agent memory can keep, rewrite, or delete facts asynchronously

Prajjwal Yd argues that memory is not about storing facts, but about deciding when a fact stops being true.
Engram handles conversational memory with an asynchronous pipeline: extract candidate memories, apply explicit keep/rewrite/delete actions, then commit the reconciled result.
Retrieval is done through Weaviate when context is needed, and the system uses topics and scopes to control what gets extracted and what can influence each memory.
The design separates project-wide memory, user-scoped memory with hard isolation, and property-scoped memory for boundaries such as a single conversation.
The visual explains that the pipeline runs non-blocking, so the agent can keep working while memory reconciliation happens in the background.
