ADR-021 Deeply Understand 代码理解引擎的 AGF 入口。Python 原生（tools/codemap/），SQLite 持久图谱 + tree-sitter 多语言 + 反向 BFS 影响分析 + 静态 HTML dashboard。替换 agf-understand（M8 验证后删 agf-understand.js）。
何时用
- 接手遗留项目 Day-1：
codemap build+onboard+dashboard - PR / 改动影响分析：
codemap diff（→ code-reviewer 审查清单） - 解释陌生文件/函数：
codemap explain - PRD/ADR 前现状理解：
codemap understand（接管 agf-understand 的理解地图）
命令（tools/codemap/ 下 uv run codemap <subcmd>）
build [path]— 全量建图 →.agf/code-map.dbupdate— 增量（git diff + 双指纹）diff [--base <ref>] [--hop N]— 变更影响分析（反向 import BFS + 风险评分）explain <target>— 节点深度解释（邻居 + 源码片段）onboard— 项目概览 + 复杂度热点 + 高扇入understand [topic]— 理解地图（目录子系统 + 核心依赖 + 风险点）context "<query>"— 相关子图（给 agent 注入）search "<query>"— 检索（默认 FTS5 关键词；跑过embed后自动启用 semantic 余弦，三态降级）embed— 生成节点 embedding 存.agf/code-map.db（需uv sync --extra semantic；jina-code-v2，首次下载 ~90MB + torch；未装/未跑则 search 自动降级 FTS，功能不中断）dashboard [--out <path>]— 静态 HTML 图（cytoscape，浏览器 open）
语言覆盖
首发 7 语言：Python / TS / JS / SQL / YAML / JSON / Java（04 设计）。Swift/WXML 诚实缺口（04 §6）。
纪律（08）
- DU 是事实层（确定性代码事实），不碰
docs/specs//docs/adr//docs/design/DESIGN.md/ OpenAPI 契约 - 产物
.agf/*gitignored（派生缓存，可重建）；消费层报告落docs/reviews/ - DU 不投票 verdict（ADR-010 不变）——给 reviewer 事实参考，verdict 仍从 findings 推导
