[FEATURE] Retrieval pipeline in code doesn’t match the paper

[BaoBaoGitHub]

Feature Request

In the current codebase, retrieval is implemented as keyword/vector/hybrid/rrf/agentic in MemoryManager.retrieve_mem, but I don’t see the MemScene selection step described in the paper (score MemScenes by max MemCell relevance, select top scenes, then pool Episodes and rerank). Foresight validity filtering also seems only partially applied depending on the path. The paper-like flow appears closer to the evaluation scripts than the main service.

Is this because the production pipeline prioritized a simpler, general retrieval flow while the paper pipeline was only implemented in eval code? Are there plans to bring the MemScene-first retrieval algorithm (and consistent Foresight validity filtering across keyword/hybrid) into the main service?

Use Case

What problem does this feature solve?
Ensure the production retrieval pipeline matches the paper (MemScene selection → Episode pooling/rerank → Foresight validity filtering), so reported results align with actual system behavior.

Who would benefit from this feature?

• End users (application developers using EverMemOS)
• Contributors/developers
• System administrators
• Other: _________________

Another question: why are foresight and event_log supported only in assistant mode, but not in group mode?

In fact, in group mode there may be multiple users, and each user would also have their own foresight and event_log.
