- #677: Feature: Semantic Memory Recall — Vector Search with Composite Scoring (Similarity + Recency + Importance)
- #42639: feat(memory): Add vector/semantic search + memory lifecycle management to built-in memory tool

- PR #44093: feat(session_search): hybrid semantic search (BM25 + sqlite-vec vectors)

This group contains two distinct themes: multiple feature proposals for semantic/vector memory systems, hybrid search, and memory lifecycle management; alongside several issues alleging plagiarism of the EvoMap/Evolver open-source project without attribution.

## TL;DR

- 17 member(s): 3 open issue(s), 8 closed issue(s), 1 open PR(s), 0 merged PR(s), 5 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.07`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
