Replace the same-origin checksum with a detached Ed25519 signature
(SHA256SUMS.sig) verified against a pinned public key before extraction,
closing #308: a compromised download mirror can no longer certify a
tampered binary. The signed manifest also binds the release version,
rejecting a forced downgrade to an older signed build.
Verification is mandatory and non-bypassable on the official download path;
custom CLOAKBROWSER_DOWNLOAD_URL mirrors keep the legacy skippable checksum.
Silent auto-update is preserved for everyone because only a constant public
key is pinned, not per-version hashes. Older installed wrappers are
unaffected — the version= line is ignored by their checksum parser.
Python uses cryptography; JS uses node:crypto. Adds tamper, downgrade, and
fail-closed tests in both languages.
Verify that HTTP errors (429, 503, etc.) from cloakbrowser.dev
correctly trigger GitHub Releases fallback for both binary and
checksum downloads. Also test that custom CLOAKBROWSER_DOWNLOAD_URL
disables fallback, and both-sources-fail returns gracefully.
Check for newer wrapper versions on startup (once per process).
Python queries PyPI, JS queries npm registry. Respects
CLOAKBROWSER_AUTO_UPDATE=false and CLOAKBROWSER_DOWNLOAD_URL
(custom mirror mode skips external registry calls).
Includes unit tests for both languages covering: update detection,
env var gating, network error handling, and once-per-process guard.
- Add PLATFORM_CHROMIUM_VERSIONS map (Linux=v145, macOS=v142)
- Add get_chromium_version()/getChromiumVersion() for platform-specific version
- Make auto-update check release assets before offering updates
- Scope version markers per-platform (latest_version_linux-x64)
- Support 5th version segment for hotfix builds (e.g. 145.0.7632.109.2)
- Derive AVAILABLE_PLATFORMS from version map
- Binary downloads now served from CloakHQ/cloakbrowser releases (chromium-v* tags)
- Auto-update: background version check on launch, downloads newer binary for next use
- Graceful error on macOS/Windows (Linux-only binaries for now)
- Rate-limited (1hr), opt-out via CLOAKBROWSER_AUTO_UPDATE=false
- Add release-binary.yml workflow for anonymous binary releases
