honcho

plastic-labs/honcho
- AGPL-3.0, Python, PostgreSQL
- 专注于“辩证推理”的记忆库。它在后台通过 LLM 提取观察结果，并构建用户与 Agent 的动态模型，支持持久的跨会话状态。
pgvector 维度 Vector(1536) 硬编码，qwen3-embedding-4b 2560 维不兼容 → 用 lancedb (VECTOR_STORE_TYPE=lancedb, VECTOR_STORE_MIGRATED=true)

注意
- pg 用的 vector，最长只有 2000 维
- halfvec, max 4000 维，但是目前无法配置
- 4b qwen3-embedding 有 2560 维，用不了

Notes

Memory Layer
Reasoning Layer
Workspaces
- -> Peers
  - -> Sessions
- -> Sessions
  - -> Messages
Global Representation
- Peer 在所有会话中的交互中提炼出来的合成见解
Local Representation
- Peer 基于特定的、观察到的交互/消息而形成的持久上下文
message → deriver(LLM) → observations → pgvector → dialectic
query → embedding → pgvector cosine 相似度检索 → top-K → 直接用
- 没有做 rerank
Dialectic（辩证）
- 带记忆的问答 agent
记忆噪音 / 清洗 / 去重
- DERIVER_DEDUPLICATE=true
  - 提取 observation 时，和已有的做相似度比对，重复的不存。
- DreamerAgent
  - 归纳（induction）：把多条零散 observation 合并成更高层抽象
  - 演绎（deduction）：从已有 observation 推断新的结论
  - 删冗余：合并后删掉原始条目
  - DREAM_ENABLED=true
- 分层 observation
  - explicit ← 直接从消息里提取的事实
  - deductive ← 从 explicit 推断的结论
