<!-- Fill in the bullets below and keep each one short and concrete: one line per bullet, roughly 10 words max
If the PR intentionally changes what existing users see or how a screen behaves, add a line under the bullets that starts "Intentional product change:" describing what changes, why, and what users lose. Reviewers must never have to infer a deliberate UX change from the diff -->

@ -28,7 +29,8 @@ How it solves it:
No LiteLLM internals: never name functions, files, DB tables, config classes, hooks, callbacks, or code paths. "The upload hands back an ID that looks like OpenAI's own `file-abc123` instead of the scrambled one the gateway returned" is right, "no managed-file row was registered" is wrong
Keep the two lists step-for-step identical until they diverge, so the changed step is obvious
If the bug had a security or authorization consequence, end each list with what another user could or could no longer do
Regenerate this section whenever new commits change the PR's behavior, so it never describes an older revision
Regenerate this section, screenshots included, whenever new commits change the PR's behavior, so it never describes an older revision
If the PR changes what an Admin UI page shows, embed a before and an after screenshot of that page right after its list, taken at the same URL on the same data, with the rows, fields, or controls that changed boxed in red so a reader spots the difference without reading the steps. These are the UI screenshots for Screenshots / Proof of Fix too: embed them once here and have that section's Before and After steps point back to them instead of repeating the images

# Rust workspace rules
## Test placement
- Never create a `tests.rs` (or `test.rs`) file under `src/`, and never `#[path = "tests.rs"] mod tests;`
- A test that reaches private items lives inline, in a `#[cfg(test)] mod tests { ... }` at the bottom of the file that owns those items
- A test that only uses the crate's public API lives in `crates/<crate>/tests/<subject>.rs`, next to `src/`
- Split a mixed test file along that line instead of widening visibility to move it
- A test for another crate's item belongs in that crate, not in a downstream one
- Never set `autotests = false` or hand-list `[[test]]` targets; every file directly under `tests/` is discovered by cargo, and a shared helper goes in `tests/<name>/mod.rs` or `tests/<subject>/support.rs` so it is not picked up as a test crate of its own
