Fixes #8990.

Description

This modifies the actions to permit running in merge queues. This is something which could be used to accelerate PR integration and automate updating PR branches when other PRs merge into dev. This should be discussed in the issue before merging.

This also removes the paths-ignore component of the main CI script as this was blocking documentation-only PRs.

Types of changes

  • Non-breaking change (fix or new feature that would not break existing functionality).
  • Breaking change (fix or new feature that would cause existing functionality to change).
  • New tests added to cover the changes.
  • Integration tests passed locally by running ./runtests.sh -f -u --net --coverage.
  • Quick tests passed locally by running ./runtests.sh --quick --unittests --disttests.
  • In-line docstrings updated.
  • Documentation updated, tested make html command in the docs/ folder.

📝 Walkthrough

Walkthrough

The build documentation, CI tests, and CodeQL workflows now trigger on GitHub merge_group events with the checks_requested type. The CI workflow now runs for all push and pull request paths. CI jobs now use pyrefly, generated dependencies, package extras, pinned Hyena dependencies, configurable package indexes, no-build-isolation installs, and an additional uv installation check.

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

Merge Risk: 🟠 High · up to de36f

Merge-group jobs can execute queued pull-request code with access to NGC credentials, creating a credible secret-exfiltration path; workflow token scope is also not explicitly constrained, and build-isolated installs may create conflicting PyTorch environments. Merge should be blocked until secret access is gated and dependency setup is corrected.

Do not expose NGC secrets to merge-group test code.

Prepare build dependencies in each workflow job.

Both pip install .[all,testing] commands use build isolation. [build-system].requires includes torch>=2.8.0, so pip can install a second PyTorch copy. Install tomli when Python is below 3.11, install generated build requirements with --no-build-isolation, and use that flag for the package install. Also update runtests.sh because --build later runs pip install -e . without the flag.

merge_group runs in the base-repository context and can receive repository secrets.

@coderabbitai how would any untrusted code which exposes these keys get into the merge queue? No code should get to the queue that hasn't been approved in a PR.

@ericspod You are correct. The merge queue runs approved PR code under your stated process. I did not establish an approval bypass. My “untrusted code” claim was incorrect.

The workflow does provide the NGC secrets to ./runtests.sh --min during merge_group, but that is consistent with treating approved merge-queue code as trusted. I withdraw the finding.

This adds the merge_group trigger for the GitHub-Actions-hosted checks, but the branch protection ruleset (ID 16034365) also requires third-party checks: DCO, DeepSource (Docker/Python/Shell), and pre-commit.ci. A merge queue entry only completes when every required check reports on the gh-readonly-queue/... branch. Have these external apps been verified to support merge_group events, or will they be excluded from the merge queue's required checks? If not, enqueued PRs will wait until the queue times out.

I don't honestly know, we might have to see if it goes through or adjust our branch rules. The DCO, pre-commit, and other checks don't need to be run again in the queue, only code that's gotten through a PR is in the queue, so it would be good to exclude them.

Removing paths-ignore means every documentation-only PR now triggers the full test matrix (min-dep across OS/Python/PyTorch combinations, full-dep, and packaging). Note that the merge_group trigger does not use path filters, so this removal is not required for merge queue support. Could you confirm the CI cost increase is intentional, and whether a lighter-weight always-required job could preserve the doc-skip behavior while still satisfying the required check?

When the doc-only PRs come through the actions don't run at all so don't get counted as passing either. This is to re-enable these until I work on a better solution involving a script to filter things and predicate actions on its output.

This workflow is currently disabled on the repository (disabled_manually), so the merge_group trigger here will not take effect until CodeQL is re-enabled.
