Suggested reviewers: Merge Risk: 🟡 Moderate · up to Fix privacy-screen failure handling before merging: a delayed window may remain on screen, and a capture-exclusion failure can leave recordings with black frames. The recorded minus hotkey also activates F12 instead. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The main risk is local recovery: delayed startup or shutdown can leave the screen outside normal cleanup, and a repeated start can report success before concealment is ready. Normal cleanup and hotkey recovery limit the impact. The examined execution path does not introduce additional script-execution privileges. Retained concerns

Review comments at
@src/one_dragon/base/controller/pc_button/pc_button_listener.py:
- Around line 29-63: Update key_to_vk to map the literal '-' recorded by
PcButtonListener to the same virtual key code as 'minus', so the privacy-screen
hotkey matches the recorded value.
Review comments at @src/script_chainer/utils/privacy_screen.py:
- Around line 519-537: Update the privacy-screen lifecycle so a stop request is
not lost when `start()` times out before the window handle is published. Give
each `_run` thread its own stop event; have `stop()` set that event before
reading `_hwnd`, and have `_run` check it after publishing the handle and post
`WM_CLOSE` when set.
- Around line 445-455: Update the window creation flow used by
PrivacyScreen.start so it applies SetWindowDisplayAffinity before showing the
window. If capture exclusion fails, destroy the window and return None; only
show and update the window after exclusion succeeds.

site:pynput.readthedocs.io/en/1.8.1 keyboard KeyCode char on_press character pynput 1.8.1
💡 Result:
The available pynput documentation I found is for **1.7.6**, not the requested **1.8.1**, so it doesn’t establish the exact 1.8.1 behavior.
In the 1.7.6 docs, `on_press(key)` receives a `KeyCode`, a special `Key`, or `None` for an unknown key. For ordinary character keys, the example reads `key.char`; special keys may not have that attribute, so it catches `AttributeError`. ([pynput.readthedocs.io](https://pynput.readthedocs.io/en/latest/keyboard.html?highlight=media&utm_source=openai))
The exact 1.8.1 documentation remains unverified. ([pynput.readthedocs.io](https://pynput.readthedocs.io/en/latest/keyboard.html?highlight=media&utm_source=openai))

让解析器识别录制到的 -。
在 Windows 的 US 键盘布局下录制 - 时，PcButtonListener 会原样提交 event.char。KeySettingCard 会保存这个值，但 key_to_vk 只映射名称 minus，不识别字面值 -。创建隐私屏时，解析失败会使主键回退为 f12，所以实际热键与录制值不同。

捕获排除失败时应让隐私屏启动失败。
如果 SetWindowDisplayAffinity 返回失败，代码已先显示黑色覆盖层，却只记录警告并继续返回窗口句柄。因此 PrivacyScreen.start() 返回 True，脚本项也报告“执行完成”；截图或录屏可能捕获黑色覆盖层，后续依赖截图的脚本可能只得到黑帧。配置明确承诺截图和录屏不会拍到隐私屏。请先设置捕获排除，成功后再显示窗口；失败时销毁窗口并返回 None。

让窗口线程关闭 stop() 请求后才创建的窗口。
start() 最多等待 5 秒。若建窗超过此时限，start() 返回 False，但后台线程仍会运行。若后续关闭操作或 runner 清理在 HWND 发布前执行，stop() 会清空 _thread 和 _hwnd，却无法发送 WM_CLOSE。join() 只等待，不会取消线程。线程随后可能显示置顶黑窗并进入消息循环；runner 再次调用 stop() 也会因 _thread 已清空而无法关闭它。若热键注册成功，可以用热键隐藏窗口；否则黑窗可能持续遮挡桌面，直到进程退出。触发条件较窄：建窗超过 5 秒，且关闭操作或 runner 清理先于 HWND 发布。
给每次启动的线程传递独立停止事件。stop() 应在读取 HWND 前设置事件；窗口线程发布 HWND 后检查事件，并发送 WM_CLOSE。

Update the privacy-screen lifecycle so a stop request is not lost when `start()`
times out before the window handle is published. Give each `_run` thread its own
stop event; have `stop()` set that event before reading `_hwnd`, and have `_run`
check it after publishing the handle and post `WM_CLOSE` when set.
