+# ("mac-pangolin-2", label `nas:host`). Neither `runs-on: mac` nor
+# `runs-on: windows` below has any runner registered to pick it up yet — this
+# workflow will queue forever until that's fixed. Options: (a) register
+# mac-pangolin-2 with an additional `mac` label (it's already a mac host —
+# cheapest fix for build-android/release-deploy) and separately stand up +
+# register an actual Windows host runner labeled `windows` for build-windows
+# (no such machine exists per docs/ci-runner.md), or (b) repoint both at
+# `nas` and accept that Android/Windows builds then compete with the
+# docker-in-domain nas jobs on the same single mac host. This mirrors the
+# `runs-on: mac` / `runs-on: windows` split already planned in

+#   - version derived via pangolin's ver_from_tag (client-v* tag; _env.sh),
+#     not jiu's ad-hoc `${TAG#client-v}` strip.
+#   - pangolin embeds sing-box as a native library (io.nekohasekai.libbox,
+#     gomobile bind) — jiu's Flutter app has no embedded core at all. This
+#     script MUST build+deploy libbox.aar (scripts/build-libbox.sh android)
+#     before `flutter build apk`, or the APK links no VPN kernel at all.
+#     Needs JDK 17 (gomobile bind javac step) — see CLAUDE.md "client/ 移动端"
+#     and "已知坑" for why: JDK 21 is rejected outright, NDK 27 fails link.
+#   - signing secrets: RELEASE_KEYSTORE (base64) + KEY_PASSWORD are the
+#     secret names given for this task ("actual configured" names). jiu uses
+#     4 separate secrets (ANDROID_KEYSTORE_BASE64/ANDROID_KEYSTORE_PASSWORD/
+#     ANDROID_KEY_ALIAS/ANDROID_KEY_PASSWORD), and pangolin's OWN prior CI
+#     design docs (docs/cicd-design.html, docs/superpowers/plans/2026-07-05-
+#     cicd.md, docs/superpowers/specs/2026-07-05-cicd-design.md) planned the
+#     same 4-secret jiu-style naming. That is a real conflict with this
+#     task's brief — see the TODO(controller) block below and the draft
+#     report. This script follows the 2-secret brief as instructed, assuming
+#     storePassword == keyPassword == KEY_PASSWORD and a derivable keyAlias
+#     (default "pangolin", overridable via optional RELEASE_KEY_ALIAS).
+#   - dart-define is PANGOLIN_API_URL (client/lib/services/api_config.dart),
+#     not jiu's BASE_URL/PUBLIC_URL/APP_VERSION trio.
+#   - build.gradle previously signed release builds with signingConfigs.debug
+#     (no release signing config existed at all) — this task's draft also
+#     wires client/android/app/build.gradle to add a `release` signingConfig
+#     that reads client/android/key.properties (falls back to debug when
+#     key.properties is absent, so local/no-secret builds still work). See
+#     report for the exact diff.
+#   - universal APK (`flutter build apk --release`, no --split-per-abi) — see
+#     report for the size-vs-single-stable-URL tradeoff discussion; this
+#     deviates from docs/superpowers/plans/2026-07-05-cicd.md Task 7 which

+#     note). Those are fetched by app/kernel/fetch-desktop-bin.sh, NOT built
+#     by scripts/build-libbox.sh — no JDK/NDK/gomobile needed on Windows.
+#   - pangolin already has a working local packaging path:
+#     client/windows/build.ps1 + client/windows/installer/pangolin.iss. This
+#     script re-implements that flow in bash (matching the repo's
+#     jiu-mirrored bash-script-per-platform convention) rather than shelling
+#     out to build.ps1, so it can apply jiu's short-path fix below.
+#   - jiu's short-path fix: the Forgejo Windows runner checks out under
+#     C:\Windows\System32\config\systemprofile\.cache\act\...\hostexecutor,
+#     which triggers WOW64 filesystem redirection that breaks CMake/Flutter
+#     native paths. jiu copies client/ to C:\jiu-build\client and builds
+#     there. pangolin's windows/CMakeLists.txt additionally resolves the
+#     kernel binaries via a path RELATIVE to CMAKE_SOURCE_DIR
+#     (client/windows/../../app/kernel/dist/desktop/windows-*  — see
+#     client/windows/CMakeLists.txt "Pangolin sing-box kernel" section), so
+#     this script must copy app/kernel/dist alongside client/ preserving the
+#     SAME relative layout (BUILD_ROOT/client + BUILD_ROOT/app/kernel/dist),
+#     not just client/ alone like jiu does — jiu has no such cross-directory
+#     kernel reference.
+#   - dart-define is PANGOLIN_API_URL, not jiu's BASE_URL/PUBLIC_URL/APP_VERSION.
+#   - pangolin.iss hardcodes `#define MyAppVersion "1.0.47"` (no #ifndef guard
+#     like jiu's jiu-installer.iss), so ISCC's /D command-line override would
+#     be silently ignored. This script `sed`s the version into the copied
+#     .iss file instead of passing /DAppVer.
