④段整套同步（六节 ＋ P/S/F/J ＋ 模板）＋ open-design 移到技能根

一、④段整套同步（用户选候选 A）
- 新增 `references/stage-proto-doc/assets/产品文档模板.html`（16 KB／247 行，从备份拷、转 LF）。
- ④段 SKILL.md 换成备份 15:28 那版，并按模板口径改齐：
  · 「产品文档框架」从「四块＋一附录」改成**六节** —— 页面结构／功能清单／使用场景／操作流程／
    跨页与界面状态／待确认与偏离；与模板同构，⛔ 不从空白页重写结构。
  · 编号从 R/S/F 改成 **P 页面／S 场景／F 功能／J 二级功能**，各自唯一、按展示顺序通排。
  · 保留旧版有价值的要求：每项功能补齐 做什么／入口在哪／输入边界／异常与恢复；重点功能三处标红；
    横向流程图每步写清页面／功能／操作／完成判据。
  · 完成标准「七节」→「六节」，自查清单同步换掉「需求」那批条目，补模板与配图两条。
  · 路径 `designs/<项目>/` → `docs/pm/<项目>/ui/`（2 处）。
  · 补回本机那条「每份产出文档开头都要有一张图」的引用（指向主 skill，段内不复述）。
- 主 skill 同步：四段结构表④行、④段沿革、画图小节（④段画页面结构图 ＋ 用户路径）。

二、open-design 移到技能根（用户选候选 A）
- `git mv product-planning/references/stage-delivery/assets/open-design → open-design/`（4178 文件）。
- `.gitignore` 白名单加 `!/open-design/` —— 否则移出去就不再纳入版本控制。
- 引用改 11 处：路径形态 `assets/open-design/...` → `<技能根>/open-design/...`；
  「随段携带的自带件」改称「同根技能」；「路径怎么找」那条改成自带件（段内相对路径）与
  同根技能（`<技能根>/<技能名>/`）两类分开写。
- open-design 自己的 ATTRIBUTION.md 两处同步（它现在与 oil-ui-pro 同层）。
- 副作用（有益）：命名闸门读数由 2063 降到 225 —— 此前它把 open-design 里 919 个第三方 md
  当成规则一起扫了；现在只扫本包 23 个 md。已确认④段的 H1 与 4a/4b/4c 子步仍在检查范围内。

三、验收
- check_naming.py --ws E:/ProgramData/AIProject/contentm_agent ＝ 通过 225 / 失败 0 / 提示 27。
- 活文件里 `assets/open-design` 残留 0；工作区 CRLF 文件 0。

+# Mobile app checklist
+
+Run this before emitting `<artifact>`. P0 must pass.
+
+## P0 — must pass
+
+- [ ] **Frame looks like a phone, not a generic card.** Dynamic Island visible, status bar SVG icons present (signal/wifi/battery), home indicator at bottom. The seed already does this — verify you didn't accidentally delete the island/rails/indicator markup.
+- [ ] **Status bar shows real glyphs**, not text like `· · · 5G · 100%`. Use the SVG icons from the seed.
+- [ ] **Home indicator is the last visible thing.** Anything below it (e.g. extra padding, accidental `<div>`) breaks the illusion.
+- [ ] **Content scrolls, frame doesn't.** `<main class="content">` has `overflow-y: auto`; the surrounding `.device` does not. The page background never moves.
+- [ ] **Tap targets ≥ 44px tall.** The seed's `.btn-primary` (48px), `.tab` (~50px), `.icon-btn` (36px ≥ touch with padding), `.list-row` (≥48px with padding) all pass. Don't ship a button under 44px.
+- [ ] **Body text ≥ 14px.** `--fs-body: 15px` already enforces this on most copy. List-row sub text uses 13px max — that's the floor.
+- [ ] **One accent, used at most twice on the screen.** Typically: one active tab + one CTA, OR one accent card + one tab. Never three.
+- [ ] **No external image URLs.** Use the `.ph-img` placeholder class. External CDN images break the OD preview iframe and look fake when they 404.
+- [ ] **Tab bar matches the screen kind.** Onboarding / detail / checkout: drop the `<nav class="tabbar">` entirely. Feed / focus / profile: keep it.
+- [ ] **Display headlines use `var(--font-display)` (serif).** The seed binds this via `.h1`, `.h2`, `.header h1`. Don't override headings to system-sans — it instantly looks like a stock template.
+- [ ] **No emoji icons in the UI.** SVG monoline only. Emoji in copy is fine ("9:41 ☀️ Tuesday" is not, but "Sunny day in Berlin" is).
+- [ ] **`data-od-id` on the device, content, header, and any major sections.**
+
+## P1 — should pass
+
+- [ ] **One screen, one job.** A profile screen does profile things. Don't graft a checkout form onto a feed.
+- [ ] **Caption above the device** names the screen (e.g. "FILEBASE · INBOX"). The seed already has the slot — fill it.
+- [ ] **Status bar time is `9:41`** (Apple convention) unless the brief asks otherwise.
+- [ ] **Mono font for numerics** — counts, prices, durations, dates. The seed's `.num` class binds this.
+- [ ] **Real, specific copy.** "Mira Hassan · CTO" beats "User Name". "$1,920" beats "$X,XXX".
+- [ ] **First-screen content fits inside the 844px frame** without requiring scroll for the primary action. If the CTA is below the fold, it's the wrong layout.
+
+## P2 — nice to have
+
+- [ ] **Subtle accent radial gradient on the page background** (already in seed). Removing it makes the device feel pasted onto a flat sheet.
+- [ ] **Backdrop-blurred tab bar** (already in seed via `backdrop-filter`).
+- [ ] **At most one image placeholder per screen.** Two placeholders on a small canvas competes for attention.
+- [ ] **Subtle metallic side rails on the bezel** (already in seed via `::before`/`::after`).
+
+## Anti-fake-device checklist
+
+If any of these are true, the screen looks like a *card pretending to be a phone* rather than a phone:
+
+- The device's outer corners aren't visibly more rounded (~56px) than the inner screen (~44px).
+- There's no Dynamic Island gap at the top centre.
+- The status bar text is grey or low-opacity (it should be `var(--fg)` at full strength).
+- The home indicator is missing.
+- The bottom tab bar has no top border or no backdrop blur.
+
+The seed prevents all of these — the most common regression is the agent rewriting the frame with `border-radius: 24px` and losing the depth.
