feat(a11y): 面板无障碍批次一——aria-live 播报网络、语义标题、焦点圈与图摘要 (#178) - #264
Conversation
- 模块级 announce()：单例 polite live region 挂 body，九处瞬时反馈 （保存/裁决/刷新/复制）统一经此播报，读屏不再依赖纯视觉 span - StatusCard 标题 div→h3（CSS margin 归零），读屏可按标题导航 - 记忆库弹层焦点管理：Tab 圈在面板内、打开焦点入面板、关闭还原 opener （两个入口按钮均标记 data-mneme-overlay-opener） - 冲突队列：busy 防重、保留 A/B 按钮带条目标题 aria-label、 裁决/刷新结果播报 - ego 关系图 role=img + 中英计数摘要键 memory.graph.summary - 新增 5 条回归测试（client.test.js 31 例全绿）
Reviewer's Guide本 PR 以模块级 aria-live 播报网络为核心，将面板保存、复制及冲突操作反馈统一暴露给读屏用户，同时把状态卡、关系图、记忆库弹层和冲突队列补齐语义、焦点管理与键盘交互，并加入针对关键实现接线的回归测试。 Sequence diagram for accessible panel feedback announcementssequenceDiagram

Hey - I've found 4 issues
Prompt for AI Agents
Please address the comments from this code review:
## Individual Comments
### Comment 1
<location path="dsh-mneme/lib/client.js" line_range="2737-2738" />
<code_context>
+ if (closeBtnRef.current) closeBtnRef.current.focus();
+ return () => {
+ window.removeEventListener("keydown", onKey);
+ const opener = document.querySelector('[data-mneme-overlay-opener]');
+ if (opener) opener.focus();
+ };
}, [open]);
</code_context>
<issue_to_address>
**issue (bug_risk):** Closing the overlay always restores focus to the first element matching `[data-mneme-overlay-opener]`, so opening from the second entry restores focus to the wrong control; if the first opener is hidden, focus is not restored at all.
**Triggers:** When both overlay entry buttons are rendered and the user opens the overlay through the second entry.
**Suggested fix:** Capture `document.activeElement` when opening and restore that exact opener during cleanup, rather than querying the first matching element.
</issue_to_address>
### Comment 2
<location path="dsh-mneme/lib/client.js" line_range="2721" />
<code_context>
+ const onKey = (e) => {
+ if (e.key === "Escape") { setOpen(false); return; }
+ if (e.key !== "Tab" || !panelRef.current) return;
+ const focusables = panelRef.current.querySelectorAll('button, input, select, textarea, a[href], [tabindex]:not([tabindex="-1"])');
+ if (focusables.length === 0) return;
+ const first = focusables[0];
+ const last = focusables[focusables.length - 1];
+ if (e.shiftKey && (document.activeElement === first || !panelRef.current.contains(document.activeElement))) {
+ e.preventDefault();
+ last.focus();
+ } else if (!e.shiftKey && document.activeElement === last) {
</code_context>
<issue_to_address>
**issue (bug_risk):** The focus trap includes disabled buttons in `focusables`. While a conflict request is busy, those buttons remain in the list even though the browser skips them during Tab navigation, so the handler fails to recognize the actual last reachable control and focus can escape the panel.
**Triggers:** When `busy` is true and the focused control is not the final disabled button in the DOM order.
**Suggested fix:** Filter out disabled controls, for example with `:not(:disabled)`, before determining the first and last focusable elements.
```suggestion
const focusables = panelRef.current.querySelectorAll('button:not(:disabled), input:not(:disabled), select:not(:disabled), textarea:not(:disabled), a[href], [tabindex]:not([tabindex="-1"])');
```
</issue_to_address>
### Comment 3
<location path="dsh-mneme/lib/client.js" line_range="3138-3144" />
<code_context>
apiFetch("/api/dsh-mneme/conflicts")
.then((res) => { if (!res.ok) throw new Error("http"); return res.json(); })
- .then((d) => setItems(d.items || []))
+ .then((d) => { setItems(d.items || []); announce(t("memory.status.conflictQueue.refreshed")); })
.catch(() => setItems([]));
};
useEffect(() => { load(); }, []);
</code_context>
<issue_to_address>
**nitpick (bug_risk):** The initial `load()` call announces `conflictQueue.refreshed` even though the user did not request a refresh, causing every status-panel visit to report a misleading “queue refreshed” event.
**Triggers:** When the status panel mounts and its initial conflicts request succeeds.
**Suggested fix:** Separate initial loading from explicit refreshes, or pass a flag to `load` and announce only for user-triggered refreshes and post-resolution reloads.
```suggestion
const load = (announceRefresh = true) => {
apiFetch("/api/dsh-mneme/conflicts")
.then((res) => { if (!res.ok) throw new Error("http"); return res.json(); })
.then((d) => { setItems(d.items || []); if (announceRefresh) announce(t("memory.status.conflictQueue.refreshed")); })
.catch(() => setItems([]));
};
useEffect(() => { load(false); }, []);
```
</issue_to_address>
### Comment 4
<location path="dsh-mneme/test/client.test.js" line_range="812-813" />
<code_context>
+ assert.ok(clientSource.includes('"role", "status"'), "live region must carry role=status");
+ // 接线点：功能开关保存、画像、向量、token、模式、extapi 保存+复制、
+ // 记忆编辑保存、队列刷新、裁决完成 —— 至少 9 处。
+ const wired = (clientSource.match(/\bannounce\(t\(/g) || []).length;
+ assert.ok(wired >= 9, `announce() wiring points expected >= 9, got ${wired}`);
+});
+
</code_context>
<issue_to_address>
**issue (testing):** The regression test only counts occurrences of `announce(t(` and does not verify that each required save, copy, refresh, and resolve path is wired. Duplicating one announcement while removing another still satisfies `wired >= 9`, so a missing feedback path silently passes the test.
**Triggers:** When a future change removes one required announce call but leaves enough duplicate calls elsewhere.
**Suggested fix:** Assert each expected translation key or each specific call site is present, rather than checking only an aggregate count.
```suggestion
for (const key of [
"memory.features.restartHint",
"memory.settings.profileSaved",
"memory.settings.vectorSaved",
"memory.settings.apiTokenSaved",
"memory.settings.mode.savedHint",
"memory.settings.extapi.savedHint",
"memory.settings.extapi.copied",
"memory.status.conflictQueue.refreshed",
"memory.status.conflictQueue.resolved",
"memory.explorer.detail.saved"
]) {
assert.ok(clientSource.includes(`announce(t("${key}")`), `announce() wiring missing for ${key}`);
}

仅在 HTTP 写入成功后播报保存成功。
apiFetch() 直接返回 fetch() 的 Promise。HTTP 401 等非 OK 响应不会触发 catch。两个处理器仍会设置成功状态并调用 announce()。请在这两个操作前检查 res.ok。

在 MemoryOverlay 边界保存实际触发器。 MemoryOverlay 当前通过文档范围的 querySelector 查找恢复目标，因此不会记录实际打开弹层的按钮。SidebarTopEntry 在宿主节点就绪前返回 SidebarFallbackTrigger，就绪后再替换为 portal 入口。如果用户从回退入口打开弹层，入口在弹层关闭前完成替换，关闭时焦点可能恢复到不同的入口。
请在打开流程中传递并保存触发按钮，在关闭时恢复该按钮的焦点。不要使用 [data-mneme-overlay-opener] 的文档范围查询。

从焦点列表中排除禁用控件。
MemoryOverlay 的处理器会把 ConflictsQueue 在 busy 状态下禁用的裁决按钮作为 last。WorkbenchSection 在加载期间可能没有后续焦点控件。此时，浏览器的实际最后可聚焦元素是队列刷新按钮。用户从该按钮按 Tab 时，边界判断不会调用 preventDefault()，焦点会离开覆盖层。

In `@dsh-mneme/lib/client.js` at line 2721, Update the focusable-element selector
in MemoryOverlay to exclude disabled buttons, inputs, selects, textareas, and
tabindex elements while retaining links and other enabled focusable controls.
Ensure focus-trap boundary handling uses only currently focusable elements,
including when ConflictsQueue is busy and WorkbenchSection has no subsequent
control.

审阅（a11y 批次一）：整体思路没问题，31/31 测试过，但发布前需要修两个行为缺陷。
1. [major] lib/client.js:3158 「仅标记已裁决」播报错误
winner === null 时三元落到 ""，会播报「已裁决：保留」且名字为空——「保留」的措辞对"无保留动作"语义也错。建议按 winner !== null 分支，并为该路径新增 conflictQueue.markedReviewed 文案键。
2. [major] lib/client.js:2737 焦点还给错了触发元素
关闭时把焦点还原到文档顺序里第一个 [data-mneme-overlay-opener]（两个入口在 4413/4501），从次要入口打开后关闭会还原到错误按钮，「焦点还给触发元素」只对了一半入口。建议 openLibrary 里用 ref 记录 event.currentTarget（或打开前记 document.activeElement），关闭时还原到它。
3. [minor] lib/client.js:3147 busy 判断 + disabled 都依赖 React 重渲染，双击仍可能双 POST /conflicts/resolve，建议加 busyRef 守卫。
4. [minor] lib/client.js:3141 初次挂载 load() 就播报「队列已刷新」，建议首载跳过播报。
5. [nit] lib/client.js:3091 role="button" 卡片内嵌 <h3>，建议把标题语义移出按钮角色。
新测试是字符串匹配，抓不到 1、2 两个问题。
Part of #178
改了什么（批次一：结构可达性）
面板反馈此前大量依赖纯视觉信号（
mneme-saved短暂 span、队列刷新无提示、裁决后静默重渲染），读屏用户无法感知。本批以最小结构补齐五块：1. aria-live 播报网络（核心）
模块级
announce()+ 单例 polite live region（挂<body>，与组件生命周期解耦），九处瞬时反馈统一走一根管子：memory.features.restartHint（复用，新增零键）memory.settings.profileSaved/vectorSaved/apiTokenSaved（复用）memory.settings.mode.savedHint/extapi.savedHint/extapi.copied（复用）memory.explorer.detail.saved（复用）conflictQueue.refreshed/conflictQueue.resolved（中英成对）2. 状态卡标题语义化
StatusCard标题div→h3（.mneme-xcolheadCSS 补margin:0防默认外边距回归），读屏用户可按标题导航状态页八张卡。3. 弹层焦点管理
记忆库 sheet：打开焦点入面板（关闭按钮为入口）→ Tab/Shift+Tab 圈在面板内 → 关闭焦点还原到触发按钮。两个入口按钮（侧边栏 footer + top entry）均标记
data-mneme-overlay-opener。4. 冲突队列可操作
resolve()加 busy 防重（连点双请求）aria-label（同文案多卡片下可区分）5. ego 关系图摘要
SVG
role="img"+aria-label（新键memory.graph.summary，中英成对）：「实体关系图：{entity} 及其 {nodes} 个节点、{edges} 条关系」。有意不做（等宿主侧联调）
var(--dsw-*)），对比度取决于宿主主题，需联调环境实测，不闭门猜测。[Feature] 面板无障碍批次一：aria-live / 焦点管理 / 逐项标注 / 图表摘要 #178 保持开放，批次二（宿主联调 + 高对比模式验证）另起。验收
node --test test/client.test.js：31/31 绿（含 5 条新回归）npm test见 CI验收观察点：读屏（NVDA/VoiceOver）下保存反馈、裁决结果、图摘要可听见；Tab 进出弹层不逃逸；Esc 关闭后焦点回到侧边栏按钮。
