🟠 Major · Route keyboard paste through ChatTextEditor.Paste(). · ChatInputArea.axaml.cs:460-465
src/Everywhere.Core/Views/Chat/ChatInputArea.axaml.cs:460-465
🎯 Functional Correctness | 🟠 Major | ⚡ Quick winRoute keyboard paste through
ChatTextEditor.Paste().This branch raises
PastingFromClipboardEvent, but the event handler does not mark it handled. The key therefore continues through the tunnel to the innerTextEditor, whose Ctrl/Cmd+V handler callsTextEditor.Paste()instead ofChatTextEditor.Paste(). This bypasses the file and bitmap format checks.Handle the key once and delegate to
ChatTextEditor.Paste(). Update the editor shortcut path to use the same method for modifier combinations that do not reach this exact-modifier branch.🤖 Prompt for AI Agents

Avalonia reports the macOS Command key as `KeyModifiers.Meta`, so every shortcut compared against `KeyModifiers.Control` alone was unreachable on macOS: Command+C/X/V in the chat input, Command+V in the terminal view, Command+1-9 assistant switching, Command+Enter sending, and Command+F/H/T in the chat window. Control kept working, which is why the gap was easy to miss. Add `KeyModifiers.HasApplicationShortcutModifier()` and `KeyModifiers.IsApplicationShortcutModifierOnly()` and use them at those call sites. The `HasFlag` form and the exact-match form stay separate helpers so that no Windows or Linux shortcut changes its semantics. `Meta` is accepted on macOS only: elsewhere it is the Windows key, and Win+V belongs to the system clipboard history. `ChatTextEditor.Paste()` no longer inserts the textual representation of a clipboard payload that the chat window attaches instead, because a copied file also offers its path as plain text on macOS. Rich payloads that carry text next to an image thumbnail keep inserting that text. `ChatWindowViewModel.AddClipboardAsync()` keeps scanning after a non-file storage item and falls back to bitmap data when no file could be added.

Description
在 macOS 上，聊天输入框里按
⌘V粘贴截图或复制的图片没有任何反应，图片不会变成附件。根因不在剪贴板代码：ChatWindowViewModel.AddClipboardAsync()本来就能正确读取位图和文件，所以输入框「+」菜单里的从剪贴板粘贴一直是正常的。坏的只有快捷键判定本身——Avalonia 把 macOS 的 Command 键上报为KeyModifiers.Meta，而这些调用点全部拿KeyModifiers.Control去比较，因此在 macOS 上永远匹配不到。在 Avalonia 12.1.2 / macOS 26.0.1 (arm64) 上用最小 Avalonia 工程实测：
剪贴板一侧不需要改动，TIFF-only 的剪贴板（即
⌘⇧⌃4截图产生的格式）已经能暴露DataFormat.Bitmap并解码：Type of Change
Current Behavior
macOS：
⌘C/⌘X/⌘V⌘V⌘1..9（切换自定义助手）⌘Enter⌘F/⌘H/⌘TControl+...Updated/Expected Behavior
以上快捷键在 macOS 上同时对
⌘和Control生效。验证方式：
⌘⇧⌃4截图后在输入框按⌘V：出现图片附件，且不掺杂多余文本；⌘C/⌘X正常复制、剪切；⌘1..9切换助手；启用「Ctrl+Enter 发送」后⌘Enter发送；⌘F/⌘H/⌘T打开搜索 / 历史 / 切换工具调用；⌘V粘贴，而Control+C仍然投递SIGINT（这一分支刻意保留只认 Control，否则⌘C会误中断进程）。Implementation Details
Everywhere.Extensions.AvaloniaExtensions中新增KeyModifiers.HasApplicationShortcutModifier()与KeyModifiers.IsApplicationShortcutModifierOnly()，语义为「Control，在 macOS 上再加 Command」。拆成两个方法是因为现有调用点本身就有两种语义：ChatTextEditor与TerminalView用HasFlag(KeyModifiers.Control)，ChatInputArea与ChatWindow用全等比较。保留两种形式，就意味着没有任何既有调用点改变自身语义。Meta只在 macOS 上被接受。在其他平台它是 Windows 键，而Win+V是系统剪贴板历史，在 Windows 上接受Meta是错的。ChatTextEditor.Paste()不再把「已被当作附件消费的剪贴板内容」的文本表示插入输入框：macOS 上复制文件时剪贴板同时提供文件路径纯文本，此前会和附件一起插入。富媒体（例如从 Office 复制、同时带正文文本与图片缩略图）仍然照旧插入文本。ChatWindowViewModel.AddClipboardAsync()遇到非file存储项时继续遍历而不是中止，并在没能添加任何文件时回落到位图数据。TerminalView的Control+C -> SIGINT完全没动，只让粘贴分支感知平台。⌘A/⌘Z不在本 PR 范围内，也未做审计。关于 Windows 与 Linux 的安全性
已运行
dotnet build src/Everywhere.Core与dotnet test tests/Everywhere.Core.Tests。457 个用例中，除ApplyPatchAsync/TransferPathAsync/DeletePathsAsync的 17 个失败外全部通过，而这 17 个在同一环境的未修改main上失败清单完全一致。此外新增的AvaloniaExtensionsTests在每个平台都锁定了修饰符契约。由于
OperatingSystem.IsMacOS()分支无法在非 macOS 主机上执行，除了跑测试外还做了穷举比对（而不是仅靠阅读代码）：取全部 16 种KeyModifiers组合与所有受影响的按键，在isMac = false下逐一比对新旧谓词，覆盖复制/剪切/粘贴、终端粘贴与SIGINT、助手切换、搜索/历史/工具调用，以及「Ctrl+Enter 发送」的两种开关状态。V/C/X+Meta(±Shift/Alt)、F/H/T+Meta、Meta触发的助手切换，以及Meta+Enter发送。Checklist
Breaking Changes
无。一处有意的跨平台行为说明：当剪贴板携带文件负载时，不再把文件路径作为文本一并插入聊天输入框。如果此前的双重行为是刻意的，请指出。
Obsoletions / Deprecations
无。
