CARD TITLE (intent, not commit subject): [lib-audit] S2-23 Mac updater is a no-op: Sparkle never fetched; feed host is not the project domain

Autonomous build of board card tsk-whwh5n.

  • Switch all feed references from taos.app to project domain taos.my:
    • mac/appcast/appcast.xml:5
    • mac/build/sparkle_sign.sh:57
    • mac/launcher/Sources/taOSLauncher/Resources/Info.plist.in:28
    • mac/launcher/Tests/taOSLauncherTests/SparkleBridgeTests.swift:7,10
  • Add fetch_sparkle.sh to mac/build/build.sh stage 4 (after frontend)
  • Update mac/build/assemble_bundle.sh to fail in release builds when:
    • Sparkle.framework is missing (previously silently skipped)
    • ed_public.pem is missing (previously silently disabled)
  • Add checksum file mac/build/checksums/sparkle-2.6.0.sha256
  • Update changelog.d/tsk-whwh5n-sparkle-domain-migration.md

This ensures security fixes reach Mac users and prevents unowned domains from intercepting updates.

Summary by CodeRabbit

  • Bug Fixes
    • Fixed macOS app updates by routing Sparkle update feeds and downloads through the project’s current domain.
    • Added verification for the Sparkle framework download to prevent corrupted or tampered updater components.
    • Release builds now fail when required Sparkle security components are missing.

…le framework fetch

- Switch all feed references from taos.app to project domain taos.my:
  - mac/appcast/appcast.xml:5
  - mac/build/sparkle_sign.sh:57
  - mac/launcher/Sources/taOSLauncher/Resources/Info.plist.in:28
  - mac/launcher/Tests/taOSLauncherTests/SparkleBridgeTests.swift:7,10
- Add fetch_sparkle.sh to mac/build/build.sh stage 4 (after frontend)
- Update mac/build/assemble_bundle.sh to fail in release builds when:
  - Sparkle.framework is missing (previously silently skipped)
  - ed_public.pem is missing (previously silently disabled)
- Add checksum file mac/build/checksums/sparkle-2.6.0.sha256
- Update changelog.d/tsk-whwh5n-sparkle-domain-migration.md

This ensures security fixes reach Mac users and prevents unowned domains from intercepting updates.

📝 Walkthrough

Walkthrough

The macOS updater now uses the taos.my domain. The build downloads and verifies Sparkle 2.6.0 before bundling. Release builds fail when required Sparkle signing assets are missing.

Changes

Sparkle updater domain and release pipeline

Layer / File(s) Summary
Updater domain migration
mac/appcast/appcast.xml, mac/build/sparkle_sign.sh, mac/launcher/.../Info.plist.in, mac/launcher/Tests/.../SparkleBridgeTests.swift
Updater feed and release URLs now use taos.my. The launcher test expects the updated feed URL.
Verified Sparkle acquisition and build wiring
mac/build/checksums/*, mac/build/fetch_sparkle.sh, mac/build/build.sh, changelog.d/*
The build downloads Sparkle 2.6.0, verifies its pinned SHA-256 checksum, extracts it into staging, and runs the fetch step before bundle assembly. Build step labels now cover 10 steps.
Release asset enforcement
mac/build/assemble_bundle.sh
Release builds fail when ed_public.pem or Sparkle.framework is missing. Non-release builds report and skip a missing framework.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 90999

Release builds can omit the updater framework or fail during update signing, while non-release builds now require network access. These build-path regressions should be fixed before merge.

Fix the release-version pattern.

The quoted fragment "[0-9]*" is literal in the Bash pattern. A normal version such as 1.0.0 does not match it. Both release guards can therefore skip their failure paths when ed_public.pem or Sparkle.framework is missing.

Use a regular expression in both conditions:

Proposed fix
-if [[ "${VERSION:-}" == "[0-9]*"* ]]; then
+if [[ "${VERSION:-}" =~ ^[0-9] ]]; then

Apply this change to both release checks.

Preserve the non-release missing-framework behavior.

build.sh requires --version, but a nonnumeric value such as dev selects the non-release branch. In that mode, the unconditional fetch_sparkle.sh call always runs curl; it does not reuse an existing $STAGING/Sparkle.framework. A download or checksum failure therefore stops the build before assemble_bundle.sh can skip the missing framework. Gate this fetch by the same release check used by assemble_bundle.sh, while keeping release failures strict.

Normalize the Sparkle extraction path.

The pinned archive extracts the macOS framework to $OUTPUT/Sparkle.xcframework/macos-arm64_x86_64/Sparkle.framework, not $OUTPUT/Sparkle.framework. assemble_bundle.sh checks only $STAGING/Sparkle.framework and exits for release builds when it is absent. Copy the framework slice to $OUTPUT/Sparkle.framework after extraction and assert that the destination exists.

Normalize bin/sign_update into the staging path.

The archive extracts bin/sign_update separately from Sparkle.xcframework/.../Sparkle.framework. Moving only Sparkle.framework leaves sparkle_sign.sh unable to find Sparkle.framework/Versions/B/Resources/sign_update. When the signing key exists, the release build then exits before producing the signature. Move or copy bin/sign_update to that expected path, preserve its executable mode, and assert that it exists after extraction.

Lead block — the fix ships zero effect; the updater stays a no-op after this PR.

Three independent reasons, each verified against the real artefact / repo:

  1. Extraction path is wrong. I downloaded Sparkle-for-Swift-Package-Manager.zip for 2.6.0: the checksum in checksums/sparkle-2.6.0.sha256 is correct (good), but the archive root contains Sparkle.xcframework/macos-arm64_x86_64/Sparkle.framework/, bin/, CHANGELOG, INSTALL, LICENSE, SampleAppcast.xml — there is no top-level Sparkle.framework. fetch_sparkle.sh therefore prints done: $OUTPUT/Sparkle.framework for a path that does not exist, and dumps bin/ and the docs into the bundle staging dir. (CR thread [3] is this.)
  2. The release guard is inert. [[ "${VERSION:-}" == "[0-9]*"* ]] — the quoted part is a literal [0-9]* in [[ ]], so it matches only a version string that begins with the characters [0-9]*. Both new exit 1 paths are unreachable; a release build with no framework still "skips". (CR thread [1].)
  3. The launcher never links Sparkle. mac/build/build.sh:42 runs swift build -c release on mac/launcher/Package.swift, which declares no Sparkle binaryTarget (it is only a comment). SparkleBridge.swift guards every real call behind #if canImport(Sparkle), so the compiled launcher is a no-op even when Sparkle.framework is copied into Contents/Frameworks. Copying the framework alone cannot fix S2-23.

The feed-domain changes (taos.app → taos.my) are right and are kept by the fix-forward. Fix-forward card carries the correct extraction, a real release flag, the binaryTarget wiring, and a post-build otool -L gate so a Mac build proves the link instead of us assuming it.

Closed mechanically: superseded by #2820.

exec/tsk-27gdvd (63753fb) is a strict superset of this PR's exec/tsk-whwh5n (909999e) — every commit here is contained there, and it carries more.

Evidence (compare/909999ebc...63753fb18): status=ahead ahead_by=2 behind_by=0. Both directions are checked: behind_by == 0 proves containment, ahead_by > 0 proves it is a strict superset rather than an identical head — one direction alone cannot tell those apart.

No work is lost. This closes the fix-forward accounting gap the per-repo throttle already assumed was closed (next_card.py:300-307), which until now nothing implemented: a fix-forward is supposed to TRADE an open slot, not add one. Reopen if this reads wrong — the predicate declines on identical, behind, and diverged heads, so a close here means containment was measured.
