feat(memory): P1 长期记忆升级 —— 异步攒批 Consolidate + 软删 + importance/last_seen
把"逐轮盲写抽取"升级为 Mem0 式对账(方案见 memory_industry_analysis.md 落地节):
mcp-go:
- Profile 加 Importance(1~10, poignancy) + LastSeenAt(为 Generative Agents 读路径
Score=w1·Relevance+w2·Recency+w3·Importance 铺路)。
- Upsert 收 importance + 每次置 last_seen(印证);新增 Delete(软删,BaseModel.DeletedAt
已具备,失效不物删可审计)+ Touch;memory_upsert 透传 importance、新增 memory_delete 工具。
dispatcher:
- extractMemory → consolidateMemory:一次 LLM 调用同时做 抽取+对账,输出
[{op:ADD|UPDATE|DELETE|NOOP,key,value,importance}];ADD/UPDATE→upsert、DELETE→软删;
sanitizeOps 防幻删(DELETE 须命中已有)/夹 importance[1,10]/同key保末个/丢 NOOP。
- 攒批:每 3 轮(per-session 计数)才 consolidate 一次,省成本,对齐 ChatGPT 周期整理。
从根上解决 exact-key 盲写的记忆腐烂。
验证:parseOps/sanitizeOps/parseProfile 纯逻辑单测;store 集成测试(真 PG)覆盖
importance/last_seen 写入 + 软删(live 0 / 物理 1);dispatcher -race 全过。
(注:完整多轮 LLM consolidate 未做实跑,属构造性验证 + 沿用已证 pool.Chat 模式。)
P2 待做:读路径按 Score(Recency+Importance) 排序/衰减/截断 + 桌面端记忆面板。
