Hippocampus

基于图结构的个人记忆，具有 HTTP + MCP 接口，是 Obsidian/Engram 的替代品。

技术栈：uv · Python 3.11+ · SQLModel + SQLite (FTS5) · FastAPI + FastMCP · Typer · Rich。

启动

uv sync                           # OBLIGATORIO
uv run hippocampus init <db-path> # bootstrap (crea BD + siembra)
uv run hippocampus serve          # HTTP+MCP en 127.0.0.1:27130

子命令：init、serve、mcp（stdio）、graph（交互式 HTML 地图，--tui 为表格视图）、backup（SQL dump）。

架构

分层干净架构（依赖方向 → 向内）：

  • api/ — HTTP/MCP 传输（零逻辑）。

  • schemas/ — API 契约（Pydantic，D26）。

  • core/ — 领域（搜索与链接、图、技术）。

  • db/、models/ — 持久化（SQLModel、FTS5、seed）。

两个空间按构造隔离（没有 space 列）：

  1. 个人（图）： 节点 → 边 → 文档 + 附件。替代 Obsidian。

  2. 技术（Engram 风格）： observations 带有 status/type。替代 Engram。

详情参见 docs/sdd-hippocampus.md（完整 SDD）和 docs/todo-hippocampus.md（检查清单）。

文档

  • docs/architecture.md — 原则与结构。

  • docs/data-model.md — 实体关系模式（8 张表 + FTS）。

  • docs/core-services.md — 领域服务（搜索与链接）。

  • docs/http-mcp-api.md — 传输层（15 个工具）。

  • docs/e2e-flows.md — 经过验证的真实流程。

  • docs/startup-and-init.md — 启动 + NO_INIT。

  • docs/runtime-launchd.md — 会话中的自动启动。

  • docs/workspace-rewiring.md — 与 psychologist 的集成。

规格（私有）

  • docs/specs/sdd-hippocampus.md — 详细设计（决策 D1–D26，需求 R1–R13）。

  • docs/specs/todo-hippocampus.md — 实施清单（阶段 0 已完成）。

  • docs/specs/sdd-obsidian-migration.md — 确定性迁移器 Obsidian→hippocampus。
