 ### Shipped
 
-The reading experience is already complete end to end: a plain-language project manual, hover annotations, a terminology dictionary, natural-language editing, and snippet Q&A, all in a bilingual UI you launch with one command (or as a native Tauri desktop app). On top of that sit a dozen deterministic, no-API-key maps — reading map, core-module ranking, test coverage, git-history hotspots and ownership, tech-debt markers, env-var surface, entry points, external integrations, silent-failure spots, under-documented files, and logic complexity. It all exports offline too: every map stitches into a single `codemap.md`, or a self-contained HTML report you can email to a non-technical stakeholder — no server, no API key, nothing fetched from the network.

Analyses also persist to a small on-disk library (`GET /api/projects`), so you can list past projects and reopen one without remembering its id or re-scanning.
 
 ### Planned
 
@@ -217,7 +217,6 @@ These are the directions I want to take next, roughly in priority order:
 - **Pull-request reading mode** — paste a PR link and get the diff explained in plain language: what changed, why it might matter, and which files to look at first. This is the most-requested extension and a natural fit for the existing annotation engine.
 - **Whole-project chat** — Q&A today is grounded in one file or snippet; the next step is a conversation that can reach across the project's maps and source at once, while staying honest about what it actually read.
 - **Annotation coverage beyond Python** — hover annotations lead with Python today; bringing JavaScript/TypeScript and Go up to the same depth is mostly prompt and tokenizer work.
-- **Persistent project library** — the project store is in-memory and single-process today; a small on-disk library would let you reopen past analyses without re-scanning.
 - **Jump-to-definition reading** — click a function or import and jump to where it's defined or used, so reading a call doesn't mean losing your place.

 ### 已交付
 
-阅读体验已经完整跑通：大白话项目说明书、悬停批注、术语词典、自然语言编辑、片段问答，全部在双语界面里，一条命令就能启动（也可以打包成 Tauri 原生桌面应用）。在这之上是十几张无需 API Key 的确定性图谱：阅读路线、核心模块排序、测试覆盖、Git 历史热点与代码归属、技术债标记、环境变量清单、程序入口、外部依赖、错误被吞点、最缺文档的文件，还有逻辑复杂度。这些还能离线导出：所有图谱可以拼成一份 `codemap.md`，或者一份自包含的 HTML 报告，直接发给不懂技术的同事或老板——不用起服务、不用 API Key、不从网上拉任何东西。

 - **PR 阅读模式**：粘贴一个 PR 链接，用大白话讲清楚这次改动改了什么、为什么可能重要、先看哪几个文件。这是被问得最多的扩展，也最贴合现有的批注引擎。
 - **整项目对话**：现在的问答只盯着单个文件或片段，下一步是让对话能同时调动项目的各张图谱和源码，同时如实交代它到底读了哪些内容。
 - **批注覆盖更多语言**：悬停批注目前优先 Python，把 JavaScript/TypeScript 和 Go 做到同样的深度，主要是 prompt 和分词的工作量。
-- **项目库持久化**：现在的项目数据存在内存里、单进程一次性，做一个小的本地项目库后，重开历史分析就不用再扫一遍。
 - **跳转到定义**：点一个函数或 import 就跳到它定义、被用的地方，读到一处调用时不会丢失上下文。
