### Fixed

- Fixed Sparkle framework integration for macOS updater
- Updated `fetch_sparkle.sh` to properly extract Sparkle 2.6.0 framework from correct archive layout (`Sparkle.xcframework/macos-arm64_x86_64/Sparkle.framework/`)
- Updated `sparkle_sign.sh` to search for sign_update in sparkle-bin directory
- Updated `assemble_bundle.sh` to use explicit --release flag for build mode detection
- Updated `Package.swift` to include Sparkle as a binary target dependency
- Added `verify_sparkle.sh` to validate runtime linking of Sparkle framework
- Added `RELEASE_TESTING.md` manual verification step for Mac builds
- Improved checksum verification to handle both shasum and sha256sum commands

- Changed Sparkle feed host from `taos.app` to project domain `taos.my` for better security
- Updated mac/appcast/appcast.xml
- Updated mac/build/sparkle_sign.sh
- Updated mac/launcher/Sources/taOSLauncher/Resources/Info.plist.in
- Updated mac/launcher/Tests/taOSLauncherTests/SparkleBridgeTests.swift

- Added fetch_sparkle.sh script to fetch and verify Sparkle 2.6.0 framework

- Modified assemble_bundle.sh to fail when Sparkle.framework is missing in release builds
- Modified assemble_bundle.sh to fail when ed_public.pem is missing in release builds

- Added mac/build/checksums/sparkle-2.6.0.sha256

- Updated mac/build/build.sh to fetch Sparkle.framework prior to bundling

S2-23: Mac updater is a no-op - security fixes never reached users

Consume --release in both argument parsers.

When either script receives --release, its loop sets RELEASE=1 without advancing the argument list. The loop then processes the same argument forever, so release assembly or verification cannot complete.

Add shift to both --release cases:

Proposed fix
-    --release) RELEASE=1 ;;
+    --release) RELEASE=1; shift ;;

Apply this change in both files.

Verify the executable at Contents/MacOS/taOS.

assemble_bundle.sh creates Contents/MacOS/taOS, and Info.plist declares taOS as CFBundleExecutable. verify_sparkle.sh checks Contents/MacOS/taOSLauncher, which is absent from every assembled bundle. The script therefore skips both linkage checks. Check the taOS path and fail in release mode when it is missing. Keep the warning-only path for development builds.

🌐 Web query:

Apple otool -l LC_RPATH output cmd path format

💡 Result:

When using the otool -l command on a Mach-O binary, the output for an LC_RPATH load command follows a standard format displaying the command details and the specific run path added [1][2]. The output generally appears as follows: Load command [N] cmd LC_RPATH cmdsize [size_in_bytes] path [the_rpath_string] (offset [offset_value]) In this format: - cmd: Identifies the load command type as LC_RPATH [3][1]. - cmdsize: Specifies the size of this load command structure, including the path string [3][4]. - path: The actual directory path (or path containing an expansion token like @executable_path or @loader_path) added to the run path search list [4][5][1][6]. - offset: The byte offset within the load command where the path string begins [1][6]. Under the hood, the Mach-O binary stores this as an rpath_command structure, defined in the Apple loader.h header as follows [3][7]: struct rpath_command { uint32_t cmd; /* LC_RPATH / uint32_t cmdsize; / includes string / union lc_str path; / path to add to run path */ }; Each LC_RPATH command represents a directory that the dynamic linker (dyld) will search when resolving libraries prefixed with the @rpath install name [4][5][2]. If multiple LC_RPATH commands exist, dyld searches them in the order they appear in the binary [4][6].

Citations:


Parse the LC_RPATH record across lines.

When "$APP/Contents/MacOS/taOSLauncher" exists, otool -l emits cmd LC_RPATH and path @executable_path/../Frameworks on separate lines. The current grep cannot match this valid record, so release verification can reject the launcher. Parse the LC_RPATH block and compare the path exactly.

Proposed fix
-    if ! otool -l "$LAUNCHER_BINARY" 2>/dev/null | grep -q "LC_RPATH.*`@executable_path/`../Frameworks"; then
+    if ! otool -l "$LAUNCHER_BINARY" 2>/dev/null | awk '
