Wires Morrison-Lab/gha's check-gradient-lhs (gha#1538, from psw#488).

Important

This PR waits on the v3 tag slide, which carries gha#1652. Until then check-caller-permissions fails with a 404 on the new workflow. The runner thread slides the tag; see gha#1654.

Adds .github/workflows/check-gradient-lhs.yml, warn-only (fail is off). This repository has no annotation gate. Infrastructure only.

I fetched PR #357 just now. It is open, not a draft, and not merged. Its head is eadff4a9dcaa234f15cdfb0a9f72206dd8494c0d, the commit I reviewed, so the review still applies.

Verdict

Ready for merge, provided the maintainer confirms the reusable workflow check-gradient-lhs.yml exists at Morrison-Lab/gha@v3. The local gha checkout doesn't contain it, and I couldn't query the remote. I found no blocking defects in the diff.

  "detailed_assessment": "The new caller workflow check-gradient-lhs.yml mirrors sibling thin callers, with correct boolean whole-tree expression and least-privilege permissions; the reusable target could not be found in the local gha checkout.",
  "holistic_assessment": "Scope is a single CI caller with no content or math changes; the remaining integration concern is confirming the upstream reusable workflow exists at the v3 tag before merge."
