…sions Keeps the existing single-job-per-OS workflow structure; no sharding. - Cache: mark the generated-suite cache cross-OS. The suite is pure codegen and identical on every platform, but today only the Build workflow (Linux) seeds the cache, so the PR workflow's Windows/macOS/ARM jobs never hit it and regenerate the whole ~99.5k-case suite on every run. enableCrossOsArchive lets them restore the Linux-seeded cache. - .gitattributes: force the settings file to LF. The cache key hashes it, so a CRLF Windows checkout would change the key (and the MSBuild regen gate) and defeat the cross-OS restore. - Bump test262harness.console 1.0.6 -> 1.1.0, actions/checkout v6 -> v7, actions/cache v5 -> v6.

A focused, structure-preserving subset of #2661 — no sharding, so the workflow keeps one job per OS (the
linux/linux - ARM/windows/macoschecks are unchanged and still report).Caching fix
The generated Test262 suite is pure codegen and byte-identical on every platform, but the cache is effectively OS-scoped and only the Build workflow (Linux) ever seeds it. So the PR workflow's Windows / macOS / ARM jobs never get a cache hit and regenerate the whole ~99.5k-case suite on every run.
Marking the cache
enableCrossOsArchive: true(on both the Build seed and the PR restore) lets every OS restore the one Linux-seeded cache. The cache key and cache action version are otherwise unchanged.The
.gitattributeschange is required for this: the cache key hashesTest262Harness.settings.json, which currently checks out CRLF on Windows (* text=auto), so without pinning it to LF the Windows key wouldn't match the Linux-seeded entry (and the MSBuild regeneration gate would also differ) — defeating the cross-OS restore.Version bumps
