+# 測試（`app/test/`）
+
+`app/` 的每個測試都適用。哪種改動跑哪些指令見 `app/AGENTS.md` § 驗證；零聯網與身分
+的規則本身也寫在那裡，這裡只寫怎麼寫測試。
+
+## 分層（ADR 0015 §決定 1）
+
+測試守契約與使用者看得到的行為，不守實作細節；行為變更同一個 PR 補測試，用能證明它
+的最低層。
+
+| 層 | 用在 | 目前的例子 |
+|---|---|---|
+| 單元 | 純邏輯、平台層實作（注入路徑與 callback，在暫存目錄上跑） | `test/platform/app_data_directory_test.dart` |
+| widget | 畫面；依賴以建構子或 provider override 注入 | `test/app/fmp_app_test.dart` |
+| 建置設定 | 原生身分：能執行就執行（`cmake -P`），不能就解析設定檔並附變異案例 | `test/identity/` |
+| 插件契約、整合、golden | M1 PR 9、PR 13 與設計系統元件加入時再寫 | — |
+
+- 正式程式碼不留測試掛鉤（`*ForTesting`、`@visibleForTesting` 的後門）；要替換的東西
+  經建構子或 provider 注入。
+- 不設覆蓋率門檻。
+
+## 零聯網
+
+`test/flutter_test_config.dart` 讓建立真實 `HttpClient` 直接拋 `StateError`；
+`dart_test.yaml` 讓 `live` tag 預設跳過。
+
+- 需要 HTTP 的程式碼注入假的 client 或 adapter，不去碰網路。
+- 真的要打真實 API 的測試：標 `tags: 'live'`，並在測試裡自己放行：
+
+  ```dart
+  final class _AllowNetwork extends HttpOverrides {}
+
+  test('...', () async {
+    await HttpOverrides.runWithHttpOverrides(() async {
+      // 這個 zone 內建立的 HttpClient 是真的
+    }, _AllowNetwork());
+  }, tags: 'live');
+  ```
+
+  執行：`flutter test --run-skipped --tags live`。
+- `flutter_test_config.dart` 先初始化測試 binding 再設 `HttpOverrides.global`：binding
+  初始化時會換上 flutter_test 自己的假 client（回 400、不報錯），順序反過來這道防線
+  就失效。
+
+## 讀原始碼或設定檔的測試
+
+優先寫行為測試。非讀原始碼不可時（例如 Gradle 設定在 CI 上跑太慢），同一個測試檔要有
+兩個變異案例：造一個違規證明解析抓得到，改一次無關的格式或命名證明結果不變。例子：
+`test/identity/android_identity_test.dart` 的 `parser mutations`。
+
+## Quality Check
+
+- `dart format --output=none --set-exit-if-changed .`、`flutter analyze` 乾淨。
+- 新的讀原始碼測試有兩個變異案例。
+- 沒有新的測試直接連網；`live` 測試在自己的 zone 放行。

+# `app/` 骨架與 CI 分流（M1 PR 2）
+
+父任務：`../09-28-m1-skeleton-tracer`（design §2、§3、§5；implement「2.」）。
+
+依據：
+- ADR 0008 §決定 2–3：App 身分；
+- ADR 0009 §決定 7：目錄規則；
+- ADR 0015 §決定 3：零聯網；§決定 8：開發版；§決定 9：CI 切分。
+
+## 做什麼
+
+1. **Flutter 專案**：`app/`，Flutter 3.47.5（Dart 3.13.4）。
+   - 以 `flutter create --org com.personal --project-name fmp --platforms android,windows,linux,macos,ios app` 為起點。
+   - `pubspec.yaml`：
+     - 是 pub workspace 根（`workspace:` 先空，PR 3 加 `packages/fmp_lints`）；
+     - `flutter: default-flavor: dev`；
+     - 依賴只加本 PR 用得到的。
+   - 範本 counter app 換成最小的 `MaterialApp`，只顯示 App 名稱與 flavor。UI 在 PR 12 做。
+2. **flavor 與 App 身分**：
+
+   | 項目 | prod（與舊版相同，ADR 0008） | dev（ADR 0015 §決定 8） |
+   |---|---|---|
+   | Android `applicationId` | `com.personal.fmp` | `com.personal.fmp.dev`（`applicationIdSuffix ".dev"`） |
+   | Android App 名稱 | `FMP` | `FMP Dev` |
+   | Windows AppUserModelID | `com.personal.fmp` | `com.personal.fmp.dev` |
+   | Windows 單一實例 mutex | `Local\FMP_MainInstance` | `Local\FMP_MainInstance-dev` |
+   | Windows 執行檔名 | `fmp.exe` | `fmp.exe`（flavor 只改身分，不改檔名） |
+   | 資料目錄 | ADR 0009 §決定 7 | 同一規則加 `-dev` |
+
+   - Android namespace 維持 `com.personal.fmp`。
+   - Android 簽名：本 PR 只用 debug 簽名；release 簽名在 PR 13 接 `key.properties`，照舊版的做法。
+   - Windows 怎麼依 flavor 設 AUMID 與 mutex，用 Flutter 3.47.5 官方支援的桌面 flavor 機制。先以 context7 或官方文件查證 `--flavor` 在 Windows 的支援方式，並把查證來源寫進 PR 描述。官方不支援時，改用 CMake 的 `FLUTTER_FLAVOR` 或 `--dart-define`，但 C++ 端要能在建立視窗前拿到值。
+   - 單一實例：第二個實例把既有視窗帶到前景後結束，行為照舊版 `windows/runner/main.cpp:12-66`。
+   - dev 的標記圖示：本 PR 只改名稱，圖示留到 PR 12。
+3. **資料目錄**（`lib/platform/` 最小實作；完整的平台層在 PR 4）：
+   - 擁有者 2026-09-29 決定：Windows Portable 版用程式旁的 `userdata/`（dev 為 `userdata-dev/`），不用 ADR 0009 原寫的 `data/`，因為它和 Flutter 的 `data/` 程式資源資料夾同名。
+   - 只做「App 資料目錄」這一項能力：Android 私有目錄；Windows 安裝版 `%APPDATA%`、Portable 版程式旁 `data/`；dev 加 `-dev`。
+   - **開發版拒絕舊版正式資料位置**：解析出的路徑若等於舊版資料位置或在它底下，直接拋錯。舊版位置要到舊專案 `lib/` 裡查（例如 `Documents\FMP`、舊 Android 私有目錄），寫進 dartdoc 並附檔名與行號。
+4. **零聯網兩道防線**（ADR 0015 §決定 3）：
+   - `app/dart_test.yaml`：`tags: live: skip:`，並用 preset 解除；
+   - `app/test/flutter_test_config.dart`：以 `HttpOverrides.global` 讓建立真實 `HttpClient` 直接拋錯；
+   - 測試：一個標 `live` 的測試在裸 `flutter test` 被跳過；以 preset 解除後，它被 `HttpOverrides` 擋下（斷言錯誤訊息）。
+5. **測試**：
+   - prod 身分的每一項等於上表，dev 的每一項都不同；
+   - Android 讀 `build.gradle.kts` 產出的值，或以 Gradle task 檢查；Windows 讀 C++／CMake 設定的常數，方式不拘，但要能在 CI 的 Linux 跑；
+   - 開發版拒絕舊版資料位置；
+   - 零聯網兩道防線。
+6. **`material_ui`**：查 3.47.5 的官方文件，決定 Material 元件的 import 路徑，寫進 `app/AGENTS.md`。
+7. **`app/AGENTS.md`**（繁中）：
+   - 只寫查不到的契約與有閘門的規則；沒有規則守的不寫；
+   - 包含：
+     - 驗證段：本 PR 起的指令；ADR 0027 的實機驗證三句（預設重播或測試插件、真實連線的條件、Android 與 Windows 每個使用者可見的 PR），skill 在 PR 11 前尚未提供，照實寫；
+     - 身分表；
+     - 零聯網；
+     - `material_ui`。
+8. **spec**：建 `.trellis/spec/app/testing/index.md`（繁中），寫零聯網與測試分層；不建 `.trellis/spec/app/index.md`（父任務 design §1）。
+9. **CI**（`.github/workflows/ci.yml`）：
+   - `dorny/paths-filter@v4`（釘 commit SHA，照現有 action 的寫法）；
+   - 觸發：`app/**` 與 `.github/**` 跑 `app` 的 job，`app/` 以外有變動就跑舊專案的三個 job；
+   - 舊 job 內容不動；
+   - `app` job：`dart format --output=none --set-exit-if-changed .`、`flutter analyze`、`flutter test`，Flutter 3.47.5；
+   - 最後一個 `always()` 彙總 job：needs 全部 job，被跳過的算通過，失敗或取消的算失敗；
+   - 檔頭註解改寫：說明為什麼現在有路徑過濾，以及為什麼文件變更仍會跑舊 job。
+10. **`orca.yaml`**：setup 加上 `app/` 的 `flutter pub get`（本 PR 還沒有 slang）。每行都要是 cmd 與 bash 共通的單一指令（照現有註解）。
+11. **Trellis 本機 agent 檔**：`trellis-check.md`、`trellis-implement.md` 第 2 步的 format／analyze 指令依 package 分流：
+    - `legacy` 維持現狀；
+    - `app` 在 `app/` 內跑 `dart format --output=none --set-exit-if-changed .` 與 `flutter analyze`。
+12. **根目錄 `AGENTS.md`**：地圖補上兩列：
+    - `app/` 一列（規則讀 `app/AGENTS.md`）；
+    - `.github/workflows/` 改寫成「`ci.yml` 依路徑分流兩個專案；`release.yml` 發舊專案」。
+    
+    只寫合併後為真的事。
+
+## 驗收
+
+- [ ] 在 `app/` 內 `flutter analyze` 零問題、`flutter test` 全綠；零聯網兩道防線的測試存在並通過。
+- [ ] 舊專案 `flutter test --exclude-tags live` 在 Flutter 3.47.5 下仍全綠（本機）。
+- [ ] Windows：
+  - `flutter build windows --flavor dev` 與 `--flavor prod` 都能建置；
+  - 同時開啟時兩個都在，各自的 AUMID 不同（主對話驗證）；
+  - 同一 flavor 開第二次，會把第一個帶到前景。
+- [ ] Android：`flutter build apk --flavor dev --debug` 與 `--flavor prod --debug`；兩個 App 能同時安裝在模擬器（主對話驗證）。
+- [ ] PR 的 CI：
+  - `app` job 與舊 job 都有跑（這個 PR 同時改到 `app/` 和根目錄）；
+  - 彙總 job 綠；
+  - 再以一個只改 `app/` 的 commit 驗證舊 job 被跳過、彙總仍綠（可在 PR 內做）。

+- https://docs.flutter.dev/deployment/flavors-windows
+  （`flutter/website` `sites/docs/src/content/deployment/flavors-windows.md`）：
+  - 「Built-in support for flavors on Windows requires Flutter 3.47 or later.」
+  - `--flavor` 時 flutter 把 flavor 寫進 `windows/flutter/ephemeral/generated_config.cmake` 的
+    `FLUTTER_APP_FLAVOR`；它在頂層 `CMakeLists.txt` 的 `add_subdirectory(${FLUTTER_MANAGED_DIR})`
+    之後才可見，`windows/runner/CMakeLists.txt` 讀得到。
+  - 建置目錄依 flavor 分開：`build/windows/<arch>/<flavor>/runner/<Config>/`。
+  - 「If you omit `--flavor`, `appFlavor` matches the default flavor configured in `pubspec.yaml`.」
+  - 客製原生設定的建議做法是在 `runner/CMakeLists.txt` 依 `FLUTTER_APP_FLAVOR` 設值。
+    文件用 `configure_file` 產生到原始碼目錄；本 PR 改用 `target_compile_definitions`
+    （Flutter 範本傳 `FLUTTER_VERSION` 給 `main.cpp` 與 `Runner.rc` 的同一個機制），
+    不產生要 gitignore 的檔案。
+- 實作 PR：flutter/flutter#187034（commit `0145a67ea8f`，`git tag --contains` 從 3.47.0 起）。
+  合併版的 `lib/src/cmake.dart:110-117` 註明「The default template does not use it」——
+  PR 描述裡「BINARY_NAME 加 `-<flavor>` 後綴」的範本改動沒有進 3.47.5 的範本
+  （`templates/app/windows.tmpl/CMakeLists.txt.tmpl:7` 仍是 `set(BINARY_NAME "{{projectName}}")`），
+  所以兩個 flavor 的執行檔都是 `fmp.exe`，符合 prd。
+- `default-flavor` 的解析：`flutter_tools/lib/src/runner/flutter_command.dart:1498-1503`，
+  `cliFlavor ?? defaultFlavor`，並加進 dart-define `FLUTTER_APP_FLAVOR`；Windows、Linux、
+  macOS、Android、iOS 裝置的 `supportsFlavors` 都是 true。
+- 實測：`flutter build windows --flavor dev`／`--flavor prod` 的 exe 版本資源與寬字串：
+  dev `ProductName=fmp-dev`、`FileDescription=FMP Dev`、`com.personal.fmp.dev`、
+  `Local\FMP_MainInstance-dev`；prod `fmp`、`FMP`、`com.personal.fmp`、`Local\FMP_MainInstance`。
+
+## 2. Android flavor
+
+- https://docs.flutter.dev/deployment/flavors（`.../deployment/flavors.md`）：
+  - Kotlin DSL：`flavorDimensions += "default"`、`productFlavors { create("staging") { dimension = ...; applicationIdSuffix = ".staging" } }`。
+  - App 名稱放 `src/<flavor>/res/values/strings.xml`，manifest 的 `android:label="@string/app_name"`。
+  - 「If your project sets `app_name` with `resValue()` … builds with AGP 9.0 or later fail by default」→ 不用 `resValue()`。
+- 實測（`aapt2 dump badging`）：`app-dev-debug.apk` 是 `com.personal.fmp.dev`／`FMP Dev`，
+  `app-prod-debug.apk` 是 `com.personal.fmp`／`FMP`。
+
+## 3. `material_ui`
+
+- https://docs.flutter.dev/release/breaking-changes/material-ui-and-cupertino-ui
+  （`.../release/breaking-changes/material-ui-and-cupertino-ui.md`）：
+  - 「In Flutter 3.47, developers can opt in to these packages ahead of the formal deprecation
+    of the in-framework design libraries.」框架內的 Material／Cupertino 自 3.44 凍結。
+  - 手動遷移：`flutter pub add material_ui`，`import 'package:material_ui/material_ui.dart';`。
+- pub.dev API：`material_ui` 1.5.0（2026-09-28），`sdk ^3.13.0`、`flutter >=3.47.0`。
+- SDK 內的 data-driven fix：`packages/flutter/lib/fix_data/fix_material/fix_material.yaml:30-35`
+  把 `package:flutter/material.dart` 換成 `package:material_ui/material_ui.dart`。
+
+## 4. pub workspace
+
+- https://dart.dev/tools/pub/workspaces（`dart-lang/site-www` `src/content/tools/pub/workspaces.md`）：
+  根 pubspec 以 `workspace:` 列成員，成員寫 `resolution: workspace`；Dart 3.11 起可用 glob。
+- 實測：`workspace: []` 在 `flutter pub get` 下可解析。
+
+## 5. 零聯網
+
+- package:test 的 preset（pub cache `test-1.31.2/doc/configuration.md:845-877`）：tag 內可寫
+  `presets: {force: {skip: false}}`，以 `-P force` 解除。
+- **`flutter test` 沒有 `--preset`**：`flutter_tools/lib/src/test/runner.dart:75-91` 組給
+  package:test 的參數只有 `--tags`／`--exclude-tags`／`--run-skipped` 等，沒有 preset；
+  `flutter test -h` 同樣沒有。所以 ADR 0015 §決定 3 的「以 preset 解除」在 `flutter test`
+  做不到，改用 `flutter test --run-skipped --tags live`。實測：裸 `flutter test` 顯示該條
+  `Skip: live: …`；`--run-skipped --tags live` 時該條執行並通過（斷言被第二道擋下）。
+- flutter_test 的 binding 初始化時會設 `HttpOverrides.global = _MockHttpOverrides()`
+  （`packages/flutter_test/lib/src/_binding_io.dart:26-28`，由 `binding.dart:1289` 呼叫）。
+  所以 `flutter_test_config.dart` 先 `TestWidgetsFlutterBinding.ensureInitialized()` 再設自己的
+  override。實測：拿掉那一行後 `test/zero_network_test.dart` 有 3 條失敗。
+
+## 6. 資料目錄與舊版位置
+
+- `path_provider_windows` 2.3.0 `lib/src/path_provider_windows_real.dart:119-120,180-210`：
+  application support 是 RoamingAppData 下的 `<CompanyName>\<ProductName>`（取自 exe 版本資源）。
+- `flutter_secure_storage_windows` 4.1.0 `lib/src/flutter_secure_storage_windows_ffi.dart:234,253`：
+  `flutter_secure_storage.dat` 寫在 application support。舊版 `Runner.rc:92,98` 是
+  `com.personal`／`fmp`，所以舊版憑證在 `%APPDATA%\com.personal\fmp`。
+- 舊版資料庫與 log：`lib/data/database/database_provider.dart:15,23-24,51`、
+  `lib/core/log_file_sink.dart:25-26`（`getApplicationDocumentsDirectory()` 下的 `FMP`）。
+- 安裝版判斷：ADR 0022 §決定 5（程式目錄有 `unins000.exe`），與舊版
+  `lib/services/update/update_service.dart:54-57` 相同。
+
+## 7. CI
+
+- `dorny/paths-filter` v4.0.3 → `ceb8a2b8f2d89434be7ff52d3de7ec3738c5cc9d`
+  （`gh api repos/dorny/paths-filter/git/ref/tags/v4.0.3`，輕量 tag 直指 commit）。
+- README（v4.0.3）：`pull_request` 以 REST API 取變動清單，需要 `pull-requests: read`；
+  push 以 git 比對，需先 checkout；推到 base 同一分支時與推送前的 commit 比。
+  `predicate-quantifier: some-with-excludes` 才能表達「符合 `**` 且不符合 `!app/**`」。
+
+## 8. 建置時發現
+
+- MSVC 以系統字碼頁（本機 950）讀 `main.cpp`，繁中註解觸發 C4819，Flutter 範本的
+  警告即錯誤讓建置失敗。`runner/CMakeLists.txt` 對 CXX 加 `/utf-8`。

+
+新 App（ADR 0008）。每條行為以 `docs/adr/` 的 ADR 為準；這裡只寫從程式碼查不到的
+契約，以及有閘門守著的規則（每條寫出它的閘門）。
+
+## 驗證
+
+在 `app/` 內執行：
+
+| 改動 | 最少要跑 |
+|---|---|
+| 任何改動 | `dart format --output=none --set-exit-if-changed .`、`flutter analyze`、`flutter test` |
+| 原生身分（`android/app/`、`windows/runner/`） | 上一列，加 `flutter build apk --flavor dev --debug`／`--flavor prod --debug` 與 `flutter build windows --flavor dev`／`--flavor prod` |
+
+- `flutter test` 不加參數：`live` 預設跳過（見「零聯網」）。CI 的 `app` job 跑的就是
+  上表第一列。
+- `test/identity/windows_identity_test.dart` 要 `cmake`：CI 的 ubuntu runner 內建；
+  Windows 的 PATH 上沒有時，測試以 vswhere 找 Visual Studio 附的那一份。
+- 不帶 `--flavor` 的 run／build 是 dev（`pubspec.yaml` 的 `default-flavor`）。
+
+### 實機驗證
+
+- 預設用 dev flavor 加測試插件，或把插件切成重播模式（ADR 0027 §決定 1）。
+- 只有改動本身是插件、網路層、登入或正在錄 fixture 時才用真實連線，只做最少的
+  操作，回報寫明「模式：真實」與做了哪些請求（ADR 0027 §決定 2）。
+- 每個使用者看得到的 PR 都要在 Android 模擬器與 Windows 驗（ADR 0027 §決定 3）。
+- `app/` 版的 `verify-on-device` skill 在 M1 PR 11 才建立；在那之前照上面三條手動
+  驗，回報寫明平台與模式。根目錄的 `verify-legacy-on-device` 只給舊專案用。
+
+## App 身分
+
+prod 與舊版相同，舊資料與憑證才讀得到（ADR 0008 §決定 3），改任何一項都要另立
+ADR；dev 每一項都不同（ADR 0015 §決定 8）。
+
+| 項目 | prod | dev | 設定在 |
+|---|---|---|---|
+| Android `applicationId` | `com.personal.fmp` | `com.personal.fmp.dev` | `android/app/build.gradle.kts` |
+| Android App 名稱 | `FMP` | `FMP Dev` | `android/app/src/<flavor>/res/values/strings.xml` |
+| Windows AppUserModelID | `com.personal.fmp` | `com.personal.fmp.dev` | `windows/runner/app_identity.cmake` |
+| Windows 單一實例 mutex | `Local\FMP_MainInstance` | `Local\FMP_MainInstance-dev` | 同上（`Local\` 前綴在 `main.cpp`） |
+| Windows 視窗標題、FileDescription | `FMP` | `FMP Dev` | 同上 |
+| Windows ProductName | `fmp` | `fmp-dev` | 同上 |
+| Windows 執行檔 | `fmp.exe` | `fmp.exe` | `windows/CMakeLists.txt` 的 `BINARY_NAME` |
+
+閘門：`test/identity/android_identity_test.dart`、`test/identity/windows_identity_test.dart`。
+沒有測試的兩處：mutex 的 `Local\` 前綴，以及 `main.cpp`／`Runner.rc` 確實讀這些定義；
+改到它們時，檢查建置出的 exe 的版本資源與內嵌的寬字串。
+
+- Android namespace 兩個 flavor 都是 `com.personal.fmp`；只有 applicationId 帶後綴。
+- Windows 的第二個實例以「視窗類別＋標題」找第一個實例帶到前景，所以兩個 flavor
+  的標題必須不同；之後若在 Dart 端改視窗標題，要一併改 `main.cpp` 的尋找方式。
+- Windows 的 ProductName 決定 path_provider 的目錄（`%APPDATA%\com.personal\<ProductName>`），
+  dev 的 application support、cache 等目錄因此全部與 prod 分開。
+
+## 資料目錄
+
+`lib/platform/app_data_directory/`（ADR 0009 §決定 7）。閘門：
+`test/platform/app_data_directory_test.dart`。
+
+- Windows 以程式目錄有沒有 `unins000.exe` 分安裝版與免安裝版（ADR 0022 §決定 5）。
+  `flutter run` 出來的是免安裝版，dev 的資料在 `build/windows/x64/dev/runner/<模式>/userdata-dev/`，
+  `flutter clean` 會一起清掉。
+- dev 解析到舊版正式資料的位置（Windows 的 `Documents\FMP` 與
+  `%APPDATA%\com.personal\fmp`、Android 舊版沙盒 `com.personal.fmp`）或其下，`main()` 在
+  `runApp` 之前就拋 `LegacyDataLocationException`：Windows 的原生視窗仍會開，但內容空白。
+
+## 零聯網
+
+ADR 0015 §決定 3 的兩道防線：
+
+- `dart_test.yaml` 讓 `live` tag 預設跳過。`flutter test` 沒有 package:test 的
+  `--preset`，解除用 `flutter test --run-skipped --tags live`。
+- `test/flutter_test_config.dart` 讓建立真實 `HttpClient` 直接拋錯；要聯網的測試在自己
+  的 zone 以 `HttpOverrides.runWithHttpOverrides` 放行。
+
+閘門：`test/zero_network_test.dart`——讀 `dart_test.yaml` 確認 `live` 預設跳過；斷言
+建立 `HttpClient` 會被擋（含 widget 測試的 binding 之下）；另有一條 `live` 測試，解除
+跳過後斷言仍被第二道擋下。
+
+## Material
+
+Flutter 3.47 起 Material 以獨立套件 `material_ui` 發佈，框架內的
+`package:flutter/material.dart` 已凍結、之後會棄用
+（https://docs.flutter.dev/release/breaking-changes/material-ui-and-cupertino-ui）。
+`app/` 一律 `import 'package:material_ui/material_ui.dart'`；`widgets.dart`、
+`services.dart` 等非設計系統的函式庫仍從 `package:flutter/` 匯入。Cupertino 同理用
+`cupertino_ui`，需要時再加依賴。
+
+閘門：`test/static_rules/material_import_static_rule_test.dart`（掃 `lib/` 與
+`test/`）。`fmp_lints`（M1 PR 3）接手後刪掉它。

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.

 `validate` 會執行程式碼產生、格式檢查、analyzer 與測試；兩個 build job 只作為跨平臺 release build 煙霧測試，不建立 GitHub Release。`*.g.dart` 等產生檔不進版本控制（見 `.gitignore`），所以本流程不對「產生檔已提交」做檢查——那類檢查在 git 從未追蹤這些檔案的情況下永遠會通過，無法真正偵測任何問題。圖示資產由維護者在本機執行 `dart run flutter_launcher_icons` 後提交，CI 不在每次驗證時重產圖示。
