fix(memory): filtrar resultados irrelevantes da busca semântica

[Joao208]

Descricao

A busca semântica do team-memory retornava todos os top N resultados independente da relevância. Resultados com score negativo (distância > 1) são semanticamente distantes e poluíam os resultados. Adicionado threshold mínimo de -0.2 para filtrar ruído.

Motivacao e Contexto

Ao buscar por termos específicos (ex: "arvore-eink cleartext"), a busca retornava todas as memórias do banco, incluindo resultados completamente irrelevantes com scores de -0.88, -0.99 etc. Isso polui o contexto do agente e desperdiça tokens.

📝 Walkthrough

Walkthrough

A minimum relevance threshold (MIN_RELEVANCE_SCORE = -0.2) was added to the semanticSearch function to filter out low-scoring results. Previously, all mapped search results were returned without filtering, regardless of relevance score.

Changes

Cohort / File(s)	Summary
Semantic Search Filtering packages/memory/src/store.ts	Added MIN_RELEVANCE_SCORE constant and post-map filtering logic to exclude semantic search results falling below the -0.2 threshold.

🐰✨ A threshold set with gentle care,
No more results unfit to share!
Below -0.2, they fade away,
Better searches light the way! 🔍
