237-237: 扩展名匹配更稳健：对“去查询串后的路径”使用 endsWith当前用 id.includes(ext) 可能被诸如 ?lang.ts 等查询参数误触发，也可能命中非文件后缀的中间片段。建议基于 cleanId（已去查询串）使用 endsWith，提高命中精度。
- if (cleanId.startsWith(normalizedSourceDir) && exts.some((ext) => id.includes(ext))) { + if (inSourceDir && exts.some((ext) => cleanId.endsWith(ext))) {若需进一步严谨，可先取真正的文件后缀再比对（注意要同时覆盖 .vue 等框架文件场景）。
236-237: Windows 大小写不敏感：建议在 win32 平台做不区分大小写的匹配在大小写可能不一致的情况下，Windows 文件系统不区分大小写，startsWith 仍可能受大小写影响。可在 win32 下将两侧统一为小写再比较，增强鲁棒性。
与上一条边界处理合并后的建议：
- let normalizedSourceDir = viteCompilerContext.sourceDir.replace(/\\/g, '/') // 👈 替换斜杠方向 - normalizedSourceDir = normalizedSourceDir.replace(/\/+$/, '') + '/' - const inSourceDir = cleanId.startsWith(normalizedSourceDir) + let normalizedSourceDir = viteCompilerContext.sourceDir.replace(/\\/g, '/') + normalizedSourceDir = normalizedSourceDir.replace(/\/+$/, '') + '/' + const isWin = process.platform === 'win32' + const a = isWin ? cleanId.toLowerCase() : cleanId + const b = isWin ? normalizedSourceDir.toLowerCase() : normalizedSourceDir + const inSourceDir = a.startsWith(b)
239-241: 建议使用 cleanId 作为 Babel 的 filename/sourceFileName传入带查询串或虚拟前缀的 id 可能影响 sourcemap 或下游插件基于 filename 的逻辑。既然已得到 cleanId，建议用于 Babel 选项，提升一致性。
- const result = await transformAsync(code, { - filename: id, + const result = await transformAsync(code, { + filename: cleanId, + sourceFileName: cleanId,

Learning: 在 NervJS/taro 项目的 .github/advanced-issue-labeler.yml 中，平台标签被设计为可以多个共存。当用户选择"所有平台"时，系统会同时应用多个平台标签（如 T-h5, T-rn, T-weapp 等），这是期望的行为而非冲突。同样，"所有小程序"也会为小程序相关的标签应用多个标签。这种设计有助于跨平台问题的管理和维护者关注。

227-237: 肯定：路径归一化修复直击问题本质，能在 Windows 下恢复 Taro API 转换处理了三类常见 Vite id 场景：移除前缀空字符、去掉查询串、将反斜杠统一为正斜杠，并同步规范 sourceDir。这样 startsWith 判定在 win32 不再失效，有助于确保 babel-plugin-transform-taroapi 被正确应用，从而解决 Taro.request 等 API 在 Windows 开发环境不可用的问题。此处改动方向正确且与 PR 目标一致。
230-237: 验证路径匹配边界已通过
- 在
/srcvs/src2、带查询串和大小写差异场景下，新逻辑（给sourceDir添加尾部斜杠再做startsWith）表现符合预期；- 原有正常匹配场景（如
C:\proj\src\app.ts）未受影响。无需进一步修改。

🛠️ Refactor suggestion
避免路径前缀误匹配：建议加“目录边界”判定
当前使用 startsWith 可能将 /src 与 /src2 误判为命中。建议在归一化后为 sourceDir 补尾随斜杠，或计算相对路径/使用边界判断，降低误伤范围。
可考虑最小变更如下：
- const normalizedSourceDir = viteCompilerContext.sourceDir.replace(/\\/g, '/') // 👈 替换斜杠方向
- if (cleanId.startsWith(normalizedSourceDir) && exts.some((ext) => id.includes(ext))) {
+ let normalizedSourceDir = viteCompilerContext.sourceDir.replace(/\\/g, '/') // 👈 替换斜杠方向
+ normalizedSourceDir = normalizedSourceDir.replace(/\/+$/, '') + '/'
+ const inSourceDir = cleanId.startsWith(normalizedSourceDir)
+ if (inSourceDir && exts.some((ext) => id.includes(ext))) {🤖 Prompt for AI Agents
In packages/taro-platform-h5/src/program.ts around lines 236 to 237, the current
use of startsWith to check if cleanId begins with normalizedSourceDir can cause
false positives when paths like <sourceDir>/src2 are mistaken for
<sourceDir>/src. To fix this, ensure normalizedSourceDir ends with a trailing
slash after normalization, then check if cleanId starts with this adjusted path
to enforce directory boundary matching and avoid incorrect matches.
