## TLDR
<!-- Fill in the bullets below and keep each one short and concrete: one line per bullet, roughly 10 words max
This section must be extremely human parsable, comprehensible, and readable: its target audience is humans, not AI agents -->
Problem this solves:
- <blah>
- ...
How it solves it:
- <blah>
- ...
## Relevant issues
<!-- e.g., "Fixes #000" -->
## Linear ticket
<!-- if you are an internal contributor, add "Resolves " followed by the Linear ticket e.g., "Resolves LIT-1234" to link the Linear ticket to the GitHub PR. If you don't have one, leave the section blank rather than guessing -->
## Pre-Submission checklist
**Please complete all items before asking a LiteLLM maintainer to review your PR**
- [ ] I have added meaningful tests
- [ ] My PR passes all CI/CD checks (e.g., lint, format, unit tests)
- [ ] 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)
## Delays in PR merge?
If you're seeing a delay in your PR being merged, ping the LiteLLM Team on [Slack (#pr-review)](https://join.slack.com/t/litellmossslack/shared_invite/zt-3o7nkuyfr-p_kbNJj8taRfXGgQI1~YyA).
## Screenshots / Proof of Fix
<!-- Include screenshots, screen recordings, or command (e.g., curl) + output demonstrating that your changes work as expected
The proof must be completely e2e with no mocks, using, for example, actual LLM calls costing real $. `pytest` commands are not enough
For bug fixes: show reproduction before the fix and passing behavior after
Include the commit hash each proof was captured at, for both the before and the after runs
If the change applies to all three LLM endpoints (/v1/responses, /v1/chat/completions, /v1/messages), include proof for every single one of them, not just one
For new features: show the feature working end-to-end
For UI changes: include before/after screenshots -->

## QA runbook
<!-- Only needed when your PR edits tests/e2e; delete this section otherwise
For each e2e test you added or changed, list the manual steps a reviewer can follow to reproduce it by hand against a live proxy, mapping 1:1 to what the test asserts: one top-level bullet per test giving its pytest node id followed by what it proves in plain words, then a nested "- [ ]" checklist where each item is a concrete action (route, request body, expected response) and the final item is the sanity-check step shown in the examples. Note environment prerequisites (provider credentials, config flags) and any nuances a manual run will hit. See PRs #32914 and #32963 for full examples
Example checklists:
- tests/e2e/quota_management/ratelimit/test_rate_limit_e2e.py::TestKeyRateLimits::test_rpm_limit_blocks_over_limit - a key allowed 2 requests a minute serves exactly 2 and refuses the 3rd
- [ ] Generate a limited key: curl -X POST http://localhost:4000/key/generate -H "Authorization: Bearer sk-1234" -d '{"rpm_limit": 2}'
- [ ] Send three /v1/chat/completions requests with that key inside one minute
- [ ] Expect the first two to return 200 and the third to return 429 naming the rpm limit
- [ ] Sanity check: this test makes sense to add and is not hand-wavey (e.g., assert actual expected spend instead of just spend > 0) or potentially flaky
- tests/e2e/management/test_management_e2e.py::TestModelRoutes::test_model_create_appears_in_ui - a deployment created through the API shows up on the Admin UI models page
- [ ] POST /model/new with the master key, a bedrock model, and aws_region_name (needs STORE_MODEL_IN_DB=True and AWS credentials)
- [ ] Open http://localhost:4000/ui/?page=models and expect a deployment row showing the returned model id
- [ ] Sanity check: this test makes sense to add and is not hand-wavey (e.g., assert actual expected spend instead of just spend > 0) or potentially flaky

### 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
