ci: publish SHA256SUMS and provenance attestations for release executables - #2471
Conversation
…executables
Percy releases shipped percy-{linux,osx,win}.zip with no checksums or
signatures, so nothing that downloads them (including BrowserStack's own
SDKs) can verify what it runs.
Add a "Publish Checksums" job to the Build Executables workflow. It runs
after the macOS build and the Windows signing job, downloads the published
zips, writes SHA256SUMS, attests all four files with GitHub artifact
attestations (Sigstore keyless; verify with `gh attestation verify`), and
uploads SHA256SUMS to the release. A workflow_dispatch trigger with a tag
input runs only this job, to backfill already-published releases.

[warning] 2-10: insufficient job-level concurrency limits (concurrency-limits): workflow is missing concurrency setting
(concurrency-limits)
A workflow_dispatch backfill downloads already-published zips it did not build, so attesting them would record the backfill run as their provenance. Backfills now publish SHA256SUMS only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Claude Code PR ReviewPR: #2471 • Head: 831c290 • Reviewers: code-review (built-in fallback; no in-scope reviewers in repo) SummaryAdds a "Publish Checksums" job to the Build Executables workflow. It writes SHA256SUMS for the three release zips and uploads it to the release. On release events it also attests the zips and SHA256SUMS with GitHub artifact attestations. A tag-scoped workflow_dispatch backfill publishes checksums only, and runs per tag are serialized with a concurrency group. Review Table
FindingsNon-blocking (no Fail rows):
Verdict: PASS |
Resolves conflicts with the eMudhra fix (#2468), release checksums (#2471) and the 1.32.12 release: - .semgrepignore: keep both new ignore blocks. - client/src/utils.js: keep master's explicit proxy agent and this branch's IPv4-first dns lookup. - cli-command/src/lockfileDiff.js: snyk-nodejs-lockfile-parser 2.10.4 (#2442) needs Node ^20.19 || ^22.13 || >=24, so a >=20 floor does not always satisfy it; keep the deferred require and say so.

Why
Part of PER-11104, item 1 (eMudhra CA compromise follow-up). Percy releases ship
percy-linux.zip,percy-osx.zipandpercy-win.zipwith no checksums or signatures, so nothing that downloads them can verify what it runs. That includes BrowserStack's own SDKs (browserstack-binary,browserstack-node-sdk), and SDK-7999 is blocked on having a hash to pin.What
A new Publish Checksums job in
executable.yml:SHA256SUMS, and uploads it to the release.percy/cli.actions/attest-build-provenanceis pinned to thev4.2.2commit SHA, per repo convention. Tag values reach shell commands only throughenv:.A
workflow_dispatchtrigger with ataginput runs only this job (build and sign are skipped), to backfill releases that are already published. The first use will bev1.32.12, the release with the eMudhra fix. Backfills publishSHA256SUMSonly, with no attestation: that run didn't build the zips, so it must not claim their provenance. Attestations start with the next published release.Consumer verification
Testing
v1.32.12assets, and the generatedSHA256SUMSverifies all three zips.v1.32.12, which is additive (it doesn't touch existing zips), and verifyshasum -c.gh attestation verifygets verified on the next published release.🤖 Generated with Claude Code
