Pre-Submission checklist

Please complete all items before asking a LiteLLM maintainer to review your PR

• I have added meaningful tests (N/A: this deletes an unreferenced markdown doc; see Proof of Fix for why no test applies)
• My PR passes all CI/CD checks (e.g., lint, format, unit tests) (all green except the pre-existing repo-wide osv-scan, which is red on other open PRs too and is unaffected by this doc-only diff)
• My PR's scope is as isolated as possible; it only solves 1 specific problem
• I have received a Greptile Confidence Score of at least 4/5 before requesting a maintainer review (Greptile reviews automatically once the PR is opened; only comment @greptileai to re-request a review after pushing changes)

Screenshots / Proof of Fix

This is a deletion of an unreferenced markdown doc, so there is no runtime behavior to exercise. The proof is that the file existed on the base branch, is gone at HEAD, and nothing in the tree references it. No meaningful automated test applies to "an unreferenced doc no longer exists"; a test asserting the absence of a file would be hollow, so none was added. The regression this guards against (a stray dashboard-as-prose doc drifting from the real Grafana dashboard) is prevented by removing the file, not by a test

Base: litellm_internal_staging. Proof captured at commit da9bb2b391

The file existed on base and is gone at HEAD:

$ git ls-tree origin/litellm_internal_staging tests/e2e/grafana/status_history_panels.md
100644 blob f8cda509c6313a76ae0d60fa3004d4babde47a96	tests/e2e/grafana/status_history_panels.md
$ git ls-files tests/e2e/grafana/
                       # empty: the file was the only thing in the directory, so the dir is gone too

Zero references anywhere in the repo (code, CI configs, mkdocs, other markdown):

$ rg -n "status_history_panels|e2e/grafana" --hidden -g '!.git'
                       # no matches (rg exit 1)

The two e2e modules that mention Grafana never depended on the doc; they only emit the E2E_RESULT logfmt lines the panels consume, and they still parse cleanly after the deletion:

$ python3.13 -c "import ast; ast.parse(open('tests/e2e/e2e_result_reporter.py').read()); ast.parse(open('tests/e2e/conftest.py').read()); print('parse OK')"
parse OK

Type

🧹 Refactoring

Changes

Deletes tests/e2e/grafana/status_history_panels.md, which was prose describing Loki/Grafana status-history panels and their LogQL queries. Nothing in the tree imports, reads, or links to it; the e2e suite only emits the E2E_RESULT lines those panels consume (tests/e2e/conftest.py, tests/e2e/e2e_result_reporter.py) and never depends on the markdown. Dashboards drift when they are versioned as prose in the code repo, so it should not live here. If we want the dashboards versioned, the right home is dashboard-as-code (Grafana JSON model / Terraform) in the observability repo, not markdown in this one

The file was the only entry in tests/e2e/grafana/, so that directory is removed as well

Final Attestation

• The tests check the right things, including the edge cases, and regressions in the respective real-world customer use-cases are not possible after this PR (deleting an unreferenced doc changes no runtime behavior and no customer-facing path)

Greptile Summary

This PR removes tests/e2e/grafana/status_history_panels.md, a prose document describing Loki/Grafana status-history panels and their LogQL queries, along with the now-empty tests/e2e/grafana/ directory. No code, CI config, or other markdown file references the deleted file.

• The deletion is consistent with the repository rule that documentation belongs in the litellm-docs repo rather than here.
• The two e2e modules that emit E2E_RESULT logfmt lines (conftest.py, e2e_result_reporter.py) never depended on this doc and are unaffected.

Confidence Score: 5/5

Safe to merge — deletes only an unreferenced markdown doc with no impact on runtime behavior or CI.

The change removes a single markdown file that no code, CI config, or other document depends on. Nothing is altered in the runtime path, test logic, or any importable module. The deletion also aligns with the repo policy of keeping documentation in the dedicated docs repo.

No files require special attention.
