+# Phase 10 Plan 01: 旧内容清空 + 站点注册 Summary
+
+**Deleted the entire legacy docs tree (guide/dev/logger/api + homepage, 162 files) and re-registered the site: config.ts decoupled from the generated apiSidebar, `generateSidebar()` guarded for the absent `docs/api`, and a 中级教程 nav + `/intermediate/` sidebar (4 groups / 24 links) wired to the empty `docs/intermediate/` landing directory so the site builds green.**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-10-17T09:34:49Z
+- **Completed:** 2026-10-17T09:39:30Z
+- **Tasks:** 2 (Task 0 approval checkpoint pre-cleared by the user's 「可以执行」)
+- **Files changed:** 164 (162 deletions + 2 modifications)
+
+## Accomplishments
+
+- Removed all legacy documentation: `docs/guide/` (23 files), `docs/dev/` (25), `docs/logger/` (4), `docs/api/` (109), and the VitePress homepage `docs/index.md` — 162 tracked files deleted.
+- Cleaned `docs/.vitepress/config.ts`: dropped the 4 legacy nav entries and the `/guide/`, `/logger/`, `/api/` sidebar keys; removed the `./apiSidebar` default import and the `./api` `generateSidebar` import; deleted the `listenSidebar()` dev plugin and its `vite.plugins` call; removed the now-unused `Plugin` type import.
+- Guarded `generateSidebar()` in `docs/.vitepress/api.ts` with `existsSync(apiDir)` so `tsx docs/.vitepress/init.ts` and `docs:dev` no longer throw `ENOENT` when `docs/api/` is absent — the per-package scan logic is untouched (D-03).
+- Registered the顶栏 `中级教程` entry (`/intermediate/data-vs-render`) and the `sidebar['/intermediate/']` key with 4 collapsed groups (概念与导航 / 基础接口 / 战斗 / 其他) and 24 links in the 4/8/9/3 order (D-20).
+- Site build passes: `cmd /c "pnpm exec tsx docs/.vitepress/init.ts && pnpm docs:build"` prints `build complete` with no dead links and no unresolved imports — the pre-existing `docs/dev/store/tile-store.md` dead-link failure is gone.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: 删除旧文档树与首页，清理 config.ts，并为 apiSidebar 生成加缺失目录守卫** - `e3d61ee` (docs)
+2. **Task 2: 在 config.ts 注册 nav 入口与 '/intermediate/' 侧边栏分组** - `ca3a61f` (docs)
+
+**Plan metadata:** (this SUMMARY commit)
+
+## Files Created/Modified
+
+- `docs/.vitepress/config.ts` - Removed legacy nav/sidebar keys, `apiSidebar`/`api` imports, `listenSidebar()` + `Plugin`; added `中级教程` nav entry and `'/intermediate/'` sidebar (24 links)
+- `docs/.vitepress/api.ts` - Added `import { existsSync } from 'node:fs'` and an early-return guard in `generateSidebar()`
+- `docs/index.md`, `docs/guide/**`, `docs/dev/**`, `docs/logger/**`, `docs/api/**` - Deleted (162 files)
+- `docs/.vitepress/apiSidebar.ts` - Deleted local gitignored generated artifact (no longer consumed)
+
+## Decisions Made
+
+- Delete legacy content outright (no redirect stubs) — D-04: the old interfaces drifted too far from the current implementation to preserve.
+- Keep the per-package `generateSidebar()` mechanism (D-03) and harden it against the missing directory rather than deleting it, so the future API-reference rebuild can reuse the scan.
+- Empty `nav`/`sidebar` containers were used as the intermediate state in Task 1, then filled with only the intermediate entries in Task 2.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+- The plan's Task 1 `<precondition>` was honored exactly: the pre-existing uncommitted `'/intermediate/'` edit in `docs/.vitepress/config.ts` was reverted (`git restore`) to HEAD before any edit, then re-applied cleanly in Task 2.
+
+## Issues Encountered
+
+None.
+
+- Pre-existing uncommitted edits to `.planning/phases/10-docs-restructure/*` (PLAN/CONTEXT/PATTERNS/RESEARCH/VALIDATION) were present before this run and were deliberately left unstaged — they are planning artifacts outside this plan's `docs/**` scope and are owned by the orchestrator/planning flow.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- `docs/` is now empty of markdown pages except the (empty) `docs/intermediate/` landing directory; the site builds green and is ready for the 24 intermediate-tutorial writing plans (10-02 .. 10-06).
+- Nav + sidebar registration is in place, so articles written into `docs/intermediate/` will be visible (D-09 human review gate).
+- No blockers.
