…Hub runners

Measures whether the Jenkins Check Test List stage can move to a GitHub runner: runner resources and docker support, container jobs, network reach to urm/artifactory and the public package indexes, and the install time, disk use and collection result for requirements-dev with CPU torch, with CUDA torch, and with GPU-only packages removed. Results are reported in the job summary; nothing is gated.

Dev Engineer Review

• The workflow probes runner resources, Docker container jobs, network reachability, dependency installation, CUDA library visibility, and check_test_list.py collection. It reports results in the job summary and does not gate the probe on install or collection failures.
• The reduced dependency probe filters packages by name pattern. Its results may not represent every GPU-only dependency or transitive dependency in requirements-dev.txt.
• The workflow runs three independent jobs and does not make the collection job depend on the runner or container-job results.

QA Engineer Review

No test changes.

Per-File QA Perspective

• .github/workflows/check-test-list-probe.yml: Adds a manually dispatched and branch-triggered diagnostic workflow. Verify the runner label, package-index access, CUDA package index, and collection summary on the target GitHub runner; the workflow’s continue-on-error steps preserve diagnostic output when installs or collection fail.

Walkthrough

The new GitHub Actions workflow reports runner and network diagnostics, checks container-job support, and runs three dependency probes. Each probe attempts test-list collection and records installation, collection, and resource results.

Changes

Test-list probe

Layer / File(s)	Summary
Probe setup and execution .github/workflows/check-test-list-probe.yml	The workflow adds runner and network diagnostics, a container-job support check, and full, CUDA-full, and reduced dependency probes. It records installation and collection outcomes, timings, disk use, and collection errors. Failed dependency installation and collection steps do not stop subsequent steps.

The informational probe can run, but its dependency installs have unnecessary access to the checkout token and potentially to write permissions. Restrict both before relying on the workflow.

Add a workflow-level permissions block.

The workflow has no permissions: block, so it uses the default token scope. Every job only reads the repository. Several jobs install third-party packages. Restrict the token to read-only access.

Based on learnings: jobs that do not push commits, tags, or releases should declare minimal workflow-level permissions such as contents: read.

Disable checkout credential persistence in the collect job.

The collect step loads llm/scripts/check_test_list.py, disables its internal pip installation, and runs module.main() with the L0, QA, waiver, validation, parity, and duplicate-waiver checks. Its visible operations use trt-test-db, pytest collection, and file handling. They do not require an authenticated Git operation.

The earlier pip installation steps can execute third-party build code in the same job. That code can access the checkout token while credentials remain persisted. In checkout v6, the token is stored in the runner temporary directory and referenced through Git configuration; it is not stored directly as a token value in llm/.git/config.
