+# Agent Note: Hover popup pointer grace
+
+Status: implemented
+
+English | [中文](2026-07-30-hover-popup-pointer-grace.zh.md)
+
+## Problem
+
+Both popups the workspace browser rows raise floated out of reach of the pointer. `HoverCard` closed on the first `pointerleave` from its anchor and rendered its card `pointer-events: none`, but the card sits 8px off the anchor's right edge, so every path to it crossed ground belonging to neither and killed the card before it arrived — the full workspace path and session title it exists to show could be read only in passing. The row action menus passed `closeOnPointerLeave`, whose handler sat on the portaled list: aiming back at the `...` trigger that opened the list closed it, and so did any overshoot past a list edge, with no window to come back.
+
+## Decision
+
+`usePointerGrace` ([packages/client/ui-primitives/src/pointer-grace.ts](../../../../packages/client/ui-primitives/src/pointer-grace.ts)) owns one cancelable delayed close, shared by both atoms, with `POINTER_GRACE_MS` at 200. Leaving arms the close; coming back cancels it. Transit through an anchor-to-popup gap is therefore survivable, while a pointer that has genuinely moved on still dismisses the popup.
+
+`HoverCard` arms the grace on leave instead of closing, and its card no longer sets `pointer-events: none`, so resting on the card holds it open. Re-entering while already open cancels the pending close without restarting the dwell, which keeps the card from blinking when the pointer crosses the gap. A press on the card starts a selection instead of dismissing it; only anchor-region presses and an owner flipping `disabled` dismiss immediately, ahead of the grace.
+
+`Menu` moves pointer-leave dismissal from the portaled list to the wrapper span. React's enter/leave traversal runs over the React tree, so the trigger and the portaled list are one region there: crossing the 4px gap between them, or aiming back at the trigger, no longer counts as leaving. Leaving is only armed while the list is open, and an owner-driven close (selection, Escape, outside click) disarms a pending grace close in an effect keyed on `open` alone — folding that into the outside-click effect would cancel the grace on every re-render, since owners pass a fresh `onClose` closure each time.
+
+## Alternatives considered
+
+**Close the popups only on outside click and Escape.** Rejected because both popups are hover-raised and unlabeled as dismissible; leaving them up after the pointer has moved to another row would strand a card over unrelated content.
+
+**Widen the anchor's hit area to abut the popup.** Rejected because the 8px and 4px offsets are the design's, and an invisible bridge element would have to track every reposition the fixed-positioned popups already do on scroll and resize.
+
+**Keep the hover card `pointer-events: none` and only add the grace.** Rejected because the pointer resting on the card would then hit whatever is behind it, so the grace would expire and close the card the user had just reached.
+
+**Give each atom its own timer.** Rejected because the two closes are the same behavior with the same tuning; a shared hook keeps them from drifting apart.
+
+## Consequences
+
+The hover card is now hit-testable and covers 244px of whatever it overlays while shown, which is the price of being reachable; it still lives only as long as the pointer is on the row or the card. Row menus survive the round trip between trigger and list, and a menu that closes for its own reason cannot be reopened into a stale pending close. Menus without `closeOnPointerLeave` are untouched — the wrapper handlers are only attached when it is set.
+
+## Testing
+
+`packages/client/ui-primitives/tests/hover-card.spec.tsx` and `tests/atoms.spec.tsx` pin the grace boundary, cancel-on-return, no-second-dwell, disarm-on-owner-close, and the no-arming-while-closed case. The reachability gestures themselves — hovering onto the card, and moving between an open list and its trigger — are pinned in the real browser by `apps/web/tests/workspace-management.e2e.ts`, since they depend on hit testing and layout that jsdom does not model.

+# Agent Note: 悬浮弹层的指针宽限期
+
+Status: implemented
+
+[English](2026-07-30-hover-popup-pointer-grace.md) | 中文
+
+## 问题
+
+工作区浏览器行弹出的两种弹层都处于指针无法抵达的位置。`HoverCard` 在指针离开锚点的第一个 `pointerleave` 上就关闭，其卡片还设置了 `pointer-events: none`；但卡片位于锚点右边缘外 8px 处，因此通往卡片的每条路径都要穿过既不属于锚点也不属于卡片的区域，卡片在指针抵达之前就已被销毁——它本应展示的完整工作区路径和会话标题只能匆匆一瞥。行操作菜单传入了 `closeOnPointerLeave`，而其处理器挂在传送后的列表上：把指针移回打开该列表的 `...` 触发按钮会关闭列表，越过列表边缘的任何一次抖动同样如此，且没有任何折返窗口。
+
+## 决策
+
+`usePointerGrace`（[packages/client/ui-primitives/src/pointer-grace.ts](../../../../packages/client/ui-primitives/src/pointer-grace.ts)）持有唯一一个可取消的延迟关闭，由两个原子组件共享，`POINTER_GRACE_MS` 为 200。离开会启动关闭，折返则取消它。因此指针可以安全穿越锚点与弹层之间的间隙，而真正移开的指针仍会关闭弹层。
+
+`HoverCard` 在离开时启动宽限期而不再立即关闭，其卡片也不再设置 `pointer-events: none`，因此指针停在卡片上即可让它保持打开。在已打开状态下重新进入只取消待执行的关闭，而不重启停留计时，从而避免指针穿越间隙时卡片闪烁。在卡片上按下指针用于开始文本选择，不会关闭卡片；只有锚点区域内的按下和所有者将 `disabled` 置真，才会抢在宽限期之前立即关闭卡片。
+
+`Menu` 把指针离开关闭的处理从传送后的列表移到包裹 span 上。React 的 enter/leave 遍历基于 React 树进行，因此触发按钮与传送后的列表在这里属于同一区域：穿越两者之间 4px 的间隙、或把指针移回触发按钮，都不再算作离开。只有在列表打开时才会启动离开关闭；由所有者驱动的关闭（选择、Escape、外部点击）会在一个仅以 `open` 为依赖的 effect 中解除待执行的宽限关闭——若把它折叠进外部点击的 effect，则每次重新渲染都会取消宽限期，因为所有者每次都传入新的 `onClose` 闭包。
+
+## 考虑过的替代方案
+
+**仅通过外部点击和 Escape 关闭这两种弹层。** 之所以否决：两者都由悬停唤起，且没有可见的关闭标识；在指针已移到其他行之后仍让它们停留，会把卡片遗留在无关内容之上。
+
+**扩大锚点的命中区域，使其与弹层相接。** 之所以否决：8px 与 4px 的偏移来自设计稿，而一个不可见的桥接元素还必须跟随这两个固定定位弹层已经在滚动和缩放时执行的每一次重新定位。
+
+**保留悬浮卡片的 `pointer-events: none`，只加入宽限期。** 之所以否决：那样指针停在卡片上时命中的是卡片背后的元素，宽限期仍会到期，并关闭用户刚刚够到的卡片。
+
+**让两个原子组件各自持有计时器。** 之所以否决：这两处关闭是同一种行为、同一套调参；共享 hook 可以防止它们各自漂移。
+
+## 后果
+
+悬浮卡片现在可被命中，显示期间会遮挡其覆盖区域的 244px——这是可抵达性的代价；它依然只在指针位于行或卡片上时存在。行菜单现在能承受触发按钮与列表之间的往返，而因自身原因关闭的菜单也不会被残留的待执行关闭重新关掉。未设置 `closeOnPointerLeave` 的菜单不受影响——只有设置该属性时才会挂上包裹层处理器。
+
+## 测试
+
+`packages/client/ui-primitives/tests/hover-card.spec.tsx` 与 `tests/atoms.spec.tsx` 固定验证宽限期边界、折返取消、不重启停留计时、所有者关闭时解除待执行关闭，以及列表关闭时不启动关闭。可抵达性手势本身——把指针移到卡片上，以及在打开的列表与其触发按钮之间移动——由 `apps/web/tests/workspace-management.e2e.ts` 在真实浏览器中固定验证，因为它们依赖 jsdom 无法建模的命中测试与布局。

+# Agent Note: Hover cards copy their primary value on activation
+
+Status: implemented
+
+English | [中文](2026-07-31-hover-card-click-copy.zh.md)
+
+## Problem
+
+Workspace and Session rows clip the two values their hover cards expose in full: the Workspace directory path and Session title. The [reachable card](../bug-fix/2026-07-30-hover-popup-pointer-grace.md) permits text selection, but selecting and copying a single known value is a needlessly precise gesture, and the card gives no confirmation that the clipboard accepted it.
+
+## Decision
+
+`HoverCard` accepts an optional `copyText` plus `copyLabel` and `copiedLabel`. With `copyText`, the whole card has button semantics for pointer and keyboard activation; its accessible name combines the localized action prefix with the exact value, it writes that value through the shared clipboard helper, and it replaces its content with the success label for up to one second only after the host accepts the write. The feedback retains the pre-copy card height and clears with the card. Without `copyText`, the atom retains its read/select-only behavior.
+
+The Workspace browser chooses the payload rather than making the primitive infer it from rendered text: a Workspace card passes the full directory path, and a non-blank Session card passes the full display title. A provisional blank New Session card remains read-only because its localized label is a placeholder, not session content. The browser's locale seat supplies `Copy`/`复制` and the success state `Copied`/`已复制`.
+
+Press and activation remain separate contracts. A pointer press inside the card keeps it mounted so text selection can begin; a completed non-collapsed selection intersecting the card suppresses pointer-click activation, while a plain click or button key activates copy. Anchor-region presses still dismiss immediately, and clipboard rejection leaves the original content visible without claiming success.
+
+## Alternatives considered
+
+**Copy the card's rendered `textContent`.** That would concatenate the primary value with creation time or running status, making the clipboard payload depend on presentation and localization.
+
+**Implement clipboard state in both Workspace card bodies.** The two consumers would duplicate host fallback, keyboard behavior, timer ownership, and success rendering even though the card owns the activation surface.
+
+**Change the common Chinese `copied` label from `复制成功` to `已复制`.** That would alter every existing copy control to satisfy one card interaction. The Workspace dictionary owns the card-specific wording instead.
+
+## Consequences
+
+Both non-placeholder hover-card variants gain the same click and keyboard affordance while retaining consumer-owned payload semantics and localized feedback. The generic atom adds one optional behavior path and a one-second timer; it clears copied state on close, ignores completion after close or unmount, and never reports a rejected write as success. Focused component coverage pins pointer selection precedence, activation, failure, feedback geometry and expiry, and cleanup, while the real-browser Workspace scenario verifies the English label, stable feedback height, and browser clipboard.

+# Agent Note（agent 决策记录）：悬浮卡片激活时复制主要值
+
+Status: implemented
+
+[English](2026-07-31-hover-card-click-copy.md) | 中文
+
+## 问题
+
+Workspace 与 Session 行会截断对应悬浮卡片完整展示的两个值：Workspace 目录路径和 Session 标题。这张[可抵达的卡片](../bug-fix/2026-07-30-hover-popup-pointer-grace.md)支持文本选择，但复制单个已知值仍需精确选择，操作没有必要地繁琐；卡片也不会确认剪贴板是否接受了写入。
+
+## 决策
+
+`HoverCard` 接收可选的 `copyText`，以及 `copyLabel` 和 `copiedLabel`。传入 `copyText` 后，整个卡片都会为指针与键盘激活提供按钮语义；其无障碍名称由本地化操作前缀和原值组成，卡片通过共享剪贴板辅助函数写入该值，并且只有宿主接受写入后，才会用成功标签替换内容最长一秒。反馈保持复制前的卡片高度，并会随卡片关闭一同清除。未传入 `copyText` 时，该原子组件维持只读且可选择文本的行为。
+
+Workspace 浏览器选择复制载荷，不让基础组件从渲染文本中推断：Workspace 卡片传入完整目录路径，非空白 Session 卡片传入完整显示标题。临时的空白「新会话」卡片保持只读，因为其本地化标签是占位文案，并非会话内容。浏览器的 locale 席位提供 `Copy`／`复制`，成功状态则使用 `Copied`／`已复制`。
+
+按下与激活仍是两份独立契约。卡片内发生指针按下时，卡片保持挂载，以便用户开始选择文本；文本选择完成后，若非折叠选区与卡片相交，就会阻止指针点击激活，而普通点击或按钮激活键会激活复制。锚点区域内发生指针按下时，卡片仍会立即消失；剪贴板拒绝写入时，卡片继续显示原内容，不会声称复制成功。
+
+## 备选方案
+
+**复制卡片渲染后的 `textContent`。** 这会把主要值与创建时间或运行状态拼接起来，使剪贴板载荷依赖表现形式和本地化结果。
+
+**在两个 Workspace 卡片主体中分别实现剪贴板状态。** 两个消费方会重复实现宿主回退、键盘行为、计时器所有权和成功状态渲染，尽管激活表层由卡片持有。
+
+**将通用中文 `copied` 标签从 `复制成功` 改为 `已复制`。** 这样会为了满足一种卡片交互而改变所有现有复制控件。卡片专用文案应由 Workspace 字典持有。
+
+## 后果
+
+两种非占位悬浮卡片都获得相同的点击与键盘操作能力，同时保留由消费方决定载荷的语义和本地化反馈。通用原子组件增加一条可选行为路径和一个一秒计时器；卡片关闭时会清除已复制状态，关闭或卸载后到达的完成结果会被忽略，写入被拒绝时绝不会报告成功。聚焦组件测试会固定指针选择文本的优先级、激活、失败、反馈尺寸与到期清除以及清理行为，真实浏览器中的 Workspace 场景则验证英文标签、反馈期间高度稳定和浏览器剪贴板。
