+## 交付记录 — 2026-10-27
+
+按上文四个工单全部落地，构建、资源校验、视口溢出探测均通过。逐项对照：
+
+| 工单 | 状态 | 落地位置 | 偏差 / 说明 |
+| --- | --- | --- | --- |
+| 1 · `/posts/` 混合归档（EN/ZH） | ✅ | `src/components/Archive.astro`、`src/lib/featured.ts`、`src/pages/posts/index.astro`、`src/pages/zh/posts/index.astro`、`src/pages/index.astro` | 旗舰集合用固定 slug（3 张归档 / 4 张首页），不用「最新 N 篇」；不做分页，仍是全量渲染 + 客户端过滤，`Ctrl+F` 与零请求都保住；筛选时旗舰块折叠为 `inert` + 高度 0，状态行从 `All 91 posts` 变为 `Showing 27 of 91 posts` |
+| 2 · `case-studies` 作品集版式 | ✅ | `src/components/PortfolioHero.astro`、`src/lib/portfolio.ts`、`src/components/PostList.astro`、`src/styles/global.css`、`src/pages/{,zh/}categories/[category].astro` | banner 从 3:1 改为 **21:9**（2400×1029），因为 3:1 在 240–300px 展示高度下纵向空间不足；连线由「三根曲线穿面板」改为共享铜总线；纯几何、无烘焙文字、seeded 确定性，重跑不产生 diff。指标 pill 只取正文出现过的数字（容器数 / VRAM / cron） |
+| 3 · 列表组件与多语言对齐 | ✅ | `src/components/PostList.astro`、`src/components/Archive.astro`、`src/styles/global.css` | 动作链接为中英双语且不进 Tab 序（每卡一个键盘停留点）；`Archive.astro` 行尾与分类 chip 原本泄漏英文 slug，已统一走 `categoryLabel()`；移动端标题链接 `min-height: 44px`。**标签 chip 仍是导航链接**（跳 `/tags/x/`），不改为页内过滤——这是先前锁定的决策，保留 |
+| 4 · 端到端验收与发布 | ✅ | `scripts/probe-layout.mjs`（新增） | 9 个页面 × 8 个视口（1920/1280/960/768/430/390/375/320）共 **72/72** 通过，`scrollWidth == clientWidth`；折叠行为在 EN/ZH × 1280/390 实测；`check-assets.mjs` 182 篇资源齐备 |
+
+验收命令：
+
+```bash
+npm run build && node scripts/check-assets.mjs
+python -m http.server 4321 --directory dist &
+chrome --headless=new --remote-debugging-port=9333 about:blank &
+node scripts/probe-layout.mjs          # 退出码 1 = 有横向溢出或折叠失效

+截图评审期间另修的三处（不在原工单内，属于同类体验缺陷）：两条 chip 条带原本无标签且视觉同构
+（`devops` 出现两次：分类 30 / 话题 6）→ 加 *Category* / *Topic* 标签、≤700px 时标签上移；
+列表卡片标签数封顶 4 个 + `+N`，修复卡片元信息行高不一致；导航补 `aria-current="page"`
+（此前四个栏目链接在任何页面都没有当前位置提示）。

+## 4e. Live re-check — 2026-10-27 (hybrid archive + case-study portfolio)
+
+Delivered the four work orders in `docs/consultant-review-2026-10-27-posts-and-casestudies-plan.md`.
+Measured, not assumed — `node scripts/probe-layout.mjs` drives a headless Chrome over CDP and
+reports **72/72** page×viewport checks with `scrollWidth == clientWidth`, plus the collapse test.
+
+- **`/posts/` and `/zh/posts/` are hybrid, not paginated.** Three fixed-slug flagship cards
+  (`src/lib/featured.ts`, 3 on the archive, 4 on the home page) sit above the complete
+  year/month archive, which still lists every post and keeps `Ctrl+F` working. Typing in the
+  filter or clicking a category chip collapses the flagship block (`inert`, height 0,
+  `data-collapsed="true"`) and the status line switches from `All 91 posts` to
+  `Showing 27 of 91 posts`; clearing restores it. Verified at 1280 and 390 in both languages.
+- **`/categories/case-studies/` is a portfolio.** `src/components/PortfolioHero.astro` — copy left,
+  a 21:9 architecture banner right (2400×1029, 33 KB WebP + a 1200 px variant, generated
+  deterministically by `scripts/gen-case-studies-banner.mjs`; pure geometry, no baked text).
+  Ordering comes from `src/lib/portfolio.ts` (`CASE_STUDY_FLAGSHIPS`, narrative order
+  scale → local AI → automation → shipped commercial result), not from `pubDate`, so publishing
+  a new post cannot rewrite the story. Every card carries a measured pill (container counts, VRAM,
+  cron counts — all read from the post body, never invented).
+- **One shipped narrative.** `lib/featured.ts` and `lib/portfolio.ts` share `pickFeatured()`, so the
+  home page, the archive and the portfolio can never disagree about which write-ups are flagship.
+- **Listing rows name their action**: `Read article →` / `Read case study →`
+  (`阅读文章 →` / `阅读案例复盘 →`), as a redundant link kept out of the tab order (`tabindex="-1"`,
+  one keyboard stop per card). Mobile title links get a 44 px minimum tap height.
+- **ZH leak fixed at the source.** `Archive.astro` printed raw category slugs in the row tail and in
+  the category chips; both now go through `categoryLabel(category, lang)` (运维架构 / 工程案例 / …).
+- **Smaller craft fixes found while reviewing screenshots**: the two chip strips were unlabelled and
+  read as one list with a duplicated `devops` (category 30 vs topic 6) → labelled *Category* / *Topic*,
+  stacked above the chips below 700 px; rows now cap tags at four plus a `+N` chip so card rhythm
+  stops breaking; the nav gained `aria-current="page"` (it had no active state at all).
+- **Docs:** `scripts/probe-layout.mjs` is committed as the repeatable gate for this class of bug.
