Screenshots / Proof of Fix

Before, on litellm_internal_staging, six cases failed because the two workflow files they parametrize over no longer exist:

$ .venv/bin/python -m pytest tests/test_litellm/test_github_triage_workflows.py -q
FAILED ...::test_llm_client_install_is_hash_pinned[review_gate.yml] - FileNotFoundError: .../.github/workflows/review_gate.yml

Changes

#30784 removed the pull_request_target Agent Shin workflows, deleting .github/workflows/review_gate.yml and .github/workflows/triage_pr_with_llm.yml. tests/test_litellm/test_github_triage_workflows.py still named both files in DESTRUCTIVE_GATE_ENV and LLM_CLIENT_INSTALLER_WORKFLOWS, and _load_workflow reads each file with no existence guard, so every parametrized case for the two deleted workflows raised FileNotFoundError.

This drops the two stale entries from both tables. The four workflows that still exist (triage_issue_with_llm.yml, close_low_quality_prs.yml, triage_reconsider.yml, triage_rollout_heads_up.yml) keep their guardrail coverage unchanged

Greptile Summary

This PR removes two stale entries (review_gate.yml and triage_pr_with_llm.yml) from the test parametrization tables in test_github_triage_workflows.py after those workflow files were deleted in #30784, restoring a clean test run.

• Drops review_gate.yml and triage_pr_with_llm.yml from DESTRUCTIVE_GATE_ENV and LLM_CLIENT_INSTALLER_WORKFLOWS; every parametrized test case for those two files was raising FileNotFoundError because _load_workflow reads the file with no existence guard.
• The four workflows that still exist (triage_issue_with_llm.yml, close_low_quality_prs.yml, triage_reconsider.yml, triage_rollout_heads_up.yml) are unchanged and keep their full guardrail coverage.

Confidence Score: 5/5

Safe to merge — removes only the two dead entries that were causing test failures after the workflow files were deleted.

The change is entirely surgical: two filename strings are removed from two lookup tables in a test file. No production code is touched, no assertions are weakened, and the four active workflows retain identical test coverage.

No files require special attention.
