-# Database access
-
-## Situations
-
-- Adding a query or an operation to a repository, read [adding a query](references/python-repository.md#adding-a-query)
-- Moving existing Prisma calls behind a repository, read [moving existing access](references/python-repository.md#moving-existing-access-into-a-repository)
-- Porting a repository from Prisma to Rust and SQLx, read [porting to SQLx](references/python-repository.md#porting-a-repository-to-sqlx)
-- Injecting a repository into a route, read [Python and FastAPI](references/python-fastapi.md) or [Rust and Axum](references/rust-axum.md)
-
-## Adding new database access
-
-- Put Python database access behind an operation in `litellm/repositories`
-- Give each repository its own FastAPI provider, so a route builds only the repositories it uses
-- A provider borrows existing handles and performs no database I/O during construction
-- Define the operations a route calls as a Protocol in `litellm/models/<feature>.py`, next to its domain types
-  - The Protocol takes and returns domain types, never Prisma models, raw rows or serialized payloads
-  - Parsing and serialization of stored values live in the repository
-  - Add a Protocol when a repository gets a provider, not up front for every repository
-- Keep query execution inside the repository, with one implementation per repository and no backend switch or fallback
-- A repository is either all Prisma or all native, never a mix of both
-- Prisma is fine for the implementation, adding a query does not require a Rust port
-- Native Rust callers use `litellm-rust/crates/db` directly
-
-## Framework wiring
-
-- Python routes receive a per-repository dependency such as `UserBannerRepositoryDep` and call its operations, such as `banners.get_banner()`
-- `DatabaseDep` lives in `litellm/proxy/deps/database.py`, repository providers in `litellm/proxy/deps/repositories.py`
-  - A provider returns the feature's Protocol, so routes never see which backend implements it
-  - Dependencies used by one feature only, like the banner audit binding, stay next to that feature's routes
-- Repositories never import FastAPI, so jobs and helpers can use them without a request
-- Use named FastAPI providers with `Annotated[..., Depends(...)]`, ordinary helpers and jobs receive explicit arguments
-- Preserve each route's no-database behavior, authorization precedence and background-task scheduling
-- Read [Python and FastAPI](references/python-fastapi.md) for provider examples, lifespan state and route verification
-- Read [Rust and Axum](references/rust-axum.md) when adding database access to Rust handlers
-
-## Connection ownership
-
-- Keep connection setup and shutdown separate from repositories, which own no pools
-- Reuse existing handles, never connect per request or disconnect from a repository operation
-- Give each pool one owner for setup and shutdown, borrowed handles never close it
-- Finish requests, jobs and queued database work before closing connections
-- Clean up resources opened before a startup failure, without a second disconnect fallback
-- Add a backend to the existing lifecycle owner and pass its handle only to repositories that need it
-- Preserve cancellation, timeout, error and transaction semantics across the native bridge
-
-## Changing ownership or reloading resources
-
-- Inventory initialization, reload, tests, background jobs and shutdown together
-- Move every writer when changing authoritative storage, copying a replaceable global into state is insufficient
-- A frozen repository does not make its clients immutable
-- Decide whether each request captures one resource generation or reads it again during processing
-- Build and validate replacements before publishing them, preserving the old generation on failure
-- Serialize reloads and coordinate publication with shutdown
-- Drain streams and background users before retiring old resources, retaining every generation grows resource use
-- Define multi-worker coordination separately from an in-process swap
-- Choose mechanisms such as `ArcSwap` only after defining publication, capture and retirement
-
-## Migration context and boundaries
-
-- Long-term direction is to centralize Python database access in repositories, then replace their Prisma implementations with Rust APIs one repository at a time
-- Prisma and native repositories coexist during the transition, unrelated existing calls can stay as they are
-- Prisma and SQLx keep separate client pools to PgBouncer, which pools connections to PostgreSQL
-  - Size both layers together and preserve reader/writer routing and pooling-mode compatibility
-- PgBouncer does not share transactions between Prisma and SQLx, keep each atomic unit of work on one backend and transaction
-- Never retry a failed Rust write through Prisma when it may already have committed
-- Prisma owns schema migrations today, eventual SQLx migration ownership and Prisma removal are separate planned steps, not part of a query port

-# Python and FastAPI
-
-## Existing pattern
-
-- `UserBannerStore` in `litellm/models/user_banner.py` is the Protocol the banner routes call
-- `get_database` in `litellm/proxy/deps/database.py` reads the lifespan-owned handle from request state
-- `get_user_banner_repository` in `litellm/proxy/deps/repositories.py` builds the banner repository from that handle
-- Choose each repository's replica routing once in its provider, never at call sites
-- A handler receives `UserBannerStore | None`, never a Prisma client or a concrete repository
-- `UserBannerRepository` implements `UserBannerStore` structurally, keeping the existing Prisma table, serialization and configuration-sync behavior
-- The banner audit provider binds the legacy audit callable at request time, without performing audit I/O
-- A native repository can later implement the same Protocol without changing handler signatures, see [porting a repository to SQLx](python-repository.md#porting-a-repository-to-sqlx)
-
-## Dependency injection
-
-- Add one provider and one `Annotated` alias per repository in `litellm/proxy/deps/repositories.py`
-- Annotate the provider and alias with the feature's Protocol, not the concrete repository
-- A route depends only on the repositories it calls, so a request never builds repositories it does not use
-- Do not build repositories once at lifespan, a reconnect can replace the Prisma client they wrap
-
-```python
-class UserBannerStore(Protocol):
-    async def get_banner(self) -> UserBanner: ...
-
-    async def save_banner(self, banner: UserBanner) -> None: ...
-```
-
-```python
-async def get_user_banner_repository(database: DatabaseDep) -> UserBannerStore | None:
-    return None if database is None else UserBannerRepository(database.prisma)
-
-
-UserBannerRepositoryDep: TypeAlias = Annotated[UserBannerStore | None, Depends(get_user_banner_repository)]
-```
-
-- FastAPI caches each provider within a request, so routes and sub-dependencies share one instance
-- Ordinary helpers and jobs receive explicit arguments, never unresolved `Depends` defaults
-- A route still reading the `prisma_client` global or building a repository inline switches to the repository's `...RepositoryDep`, keeping its no-database behavior and error precedence
-
-```python
-async def get_user_banner(banners: UserBannerRepositoryDep) -> UserBanner:
-    if banners is None:
-        return UserBanner()
-    return await banners.get_banner()
-```
-
-## Lifespan state
-
-- Prisma startup owns connection setup, authentication refresh, health checks and migrations
-- `Database` holds the initialized Prisma client and the `NativeDatabase` handle, without holding fields per feature
-  - The native handle opens no pool yet, its `connect` and `close` are noops
-- The proxy lifespan builds the handle with `Database.open`, registers `Database.aclose` on its exit stack and publishes it in request state
-  - Callers only open and close `Database`, which closes Prisma and the native handle together, and `open` closes Prisma itself when the native connect fails
-- Starlette shallow-copies lifespan state into request state, which is distinct from `app.state`
-- The database module never imports a repository, legacy globals borrow its handle without owning shutdown
-- Drain requests, jobs, logging, spend and audit work before database teardown
-- The exit stack closes the handle on exit, including startup failures after the client is created
-- When adding native resources, initialize them in the serving process, respecting runtime fork restrictions
-- Await native shutdown instead of depending on Python garbage collection
-- Apply the [connection ownership rules](../SKILL.md#connection-ownership) when changing the owner
-
-## Timing and errors
-
-- FastAPI resolves dependencies before entering the handler
-- Handler exception handling cannot catch failures raised during dependency resolution
-- A universal required-database dependency can override authorization and validation behavior
-- Banner GET without a database returns the default disabled banner
-- Banner PATCH checks the admin role before returning the existing missing-database error
-- Invalid stored banner data falls back to the default, but storage failures still propagate
-- Banner writes finish before the success audit is queued as a FastAPI background task
-- Queue post-response work with `BackgroundTasks`, not bare `asyncio.create_task`, so the in-flight drain waits for it before the database closes
-- Do not move background work into an awaited provider merely to remove an import
-
-## Verification
-
-- Exercise real FastAPI handlers using `dependency_overrides` for external boundaries
-- Keep production parsing and persistence code real
-- Restore overrides after each test
-- Verify complete response bodies, status codes and OpenAPI against the base
-- Include combined failure conditions to pin error precedence
-- Check saved values, fresh revisions, audit contents and failed-write behavior
-- Check lifespan state with a running lifespan, not only a TestClient that skips startup
-- Verify providers do not connect, query, disconnect or audit eagerly
-- Use real PostgreSQL and live proxy requests when changing persistence behavior
-
-## Scope
-
-- Preserve direct Python call sites or migrate them explicitly
-- Inventory imports, state writers, side effects and error ordering before migrating a feature
-- Preserve configuration sync and serialization, and state which legacy reads remain
-- Do not migrate every route in a large module just to establish the pattern
-- Do not invent providers for resources without consumers

-# Python repositories
-
-## Adding a query
-
-Use this when a feature needs a read or write that no repository offers yet, including one more operation on an existing repository
-
-### Before starting
-
-- Search `litellm/repositories` for a repository that already owns the table, and extend it instead of adding a second one
-- Check `litellm/models/<feature>.py` for an existing Protocol and domain types
-- Decide the route's behavior when no database is configured, and where that check sits relative to authorization and validation
-
-### Steps
-
-1. Domain types and Protocol in `litellm/models/<feature>.py`
-   - The Protocol takes and returns domain types, never Prisma models, raw rows or serialized payloads
-   - Add the Protocol together with the provider, not for repositories nothing injects
-2. Repository in `litellm/repositories/<feature>_repository.py`
-   - Implement the operation with Prisma, a Rust port is not required
-   - Compose the Prisma client and type the tables it touches with `TableActions` from `prisma_protocols.py`, never inherit `PrismaTableRepository`
-   - Parse and serialize stored values here, so callers only see domain types
-   - Never import FastAPI, connect, disconnect or choose replicas per call
-3. Provider and `Annotated` alias in `litellm/proxy/deps/repositories.py`, see [dependency injection](python-fastapi.md#dependency-injection)
-4. The route takes `<Feature>RepositoryDep`, handles `None` with the behavior decided above, and calls the operation
-5. Jobs and helpers that need the operation receive the repository as an explicit argument, built by their caller from the handle it already holds
-
-### Done when
-
-- Handler tests drive the real route with `dependency_overrides` and the real repository code, see [verification](python-fastapi.md#verification)
-- Tests cover the no-database path, error precedence, and what was actually stored
-- Persistence changes are checked against real PostgreSQL through a live proxy
-
-### Out of scope
-
-- Porting the query to Rust, see [porting a repository to SQLx](#porting-a-repository-to-sqlx)
-- Moving unrelated direct Prisma calls in the same module
-
-## Moving existing access into a repository
-
-Use this when code calls Prisma directly, through `prisma_client.db.<table>` or a helper, and the calls should live behind a repository. The backend stays Prisma
-
-### Before starting
-
-- List every call being moved, its callers, and the transaction or batch it runs in
-- List the module's imports, global state writers, side effects such as audit and config sync, and error ordering
-- Record current return values, raised errors and response bodies, these are what the change must preserve
-
-### Steps
-
-1. Move the existing Prisma code into the relevant repository in `litellm/repositories` without rewriting the queries
-2. Add domain types and a Protocol in `litellm/models/<feature>.py` when a route will inject the repository
-3. Replace each direct call with the repository operation, through a provider for routes and explicit arguments for jobs and helpers, see [Python and FastAPI](python-fastapi.md)
-4. Calls sharing a transaction move into the same repository or unit of work in one change
-5. State which legacy reads remain and why, when the change does not move all of them
-
-### Done when
-
-- Focused regression tests pin the preserved return values, errors and transaction behavior
-- Response bodies, status codes and OpenAPI match the base
-- Configuration sync and serialization behave the same, including invalid stored data
-
-### Out of scope
-
-- Switching the backend, even when an equivalent Rust query exists
-- Converting other routes in the module just to establish the pattern
-- Cleanups unrelated to the moved calls
-
-## Porting a repository to SQLx
-
-Status: TBD. No repository has been ported yet. `database.native` is a `NativeDatabase` from `crates/python-bridge/src/db.rs` whose `connect` and `close` are noops that open no pool, and the PyO3 repository surface does not exist. A real pool takes typed writer/reader settings and a token provider, never the Prisma `DATABASE_URL`, which carries Prisma-only params and rotating IAM tokens. The constraints below are settled, the steps are a sketch to revise after the first port lands
-
-Use this only when a port is explicitly requested. Repository extraction does not require one
-
-### When not to port
-
-- An equivalent Rust or SQLx query existing is not a reason to switch a Prisma caller
-- Leave existing backend selection unchanged unless integration is explicitly requested
-- Never port part of a repository, it is either all Prisma or all native
-
-### Before starting
-
-- Identify the repository's inputs, outputs, errors and transaction boundary
-- List repositories that share a transaction with it, they move together
-- Check `litellm-rust/crates/db` for an equivalent query and reuse it when its behavior matches
-
-### Steps
-
-1. Rust queries, following `litellm-rust/crates/db/AGENTS.md`
-   - Static SQL in `queries/`, compile-checked with SQLx, typed inputs and row projections in `src/`
-   - Dynamic filters and sort keys become closed Rust enums that select static SQL, every value is bound
-   - Refresh SQLx query metadata after SQL changes
-2. PyO3 surface exposing typed operations, never SQL text, table names or column names from Python. TBD: where it lives and how the handle reaches it
-3. Native repository implementing the same Protocol in `litellm/repositories`
-   - Converts typed PyO3 results to domain types, preserving defaults, invalid-data handling and storage errors
-   - Python conversion stays in the bridge, not in `crates/db`
-4. Switch the provider in `litellm/proxy/deps/repositories.py`, the Protocol and routes stay unchanged
-
-```diff
- async def get_user_banner_repository(database: DatabaseDep) -> UserBannerStore | None:
--    return None if database is None else UserBannerRepository(database.prisma)
-+    return None if database is None else NativeUserBannerRepository(database.native)
-```
-
-5. Delete the Prisma repository in the same change and switch every caller, including jobs and helpers
-
-### Done when
-
-- Behavior is verified against real PostgreSQL, covering null handling, conflicts, ordering, errors and transaction semantics
-- `DATABASE_URL=... cargo test -p litellm-db --locked -- --include-ignored` passes against a Prisma-migrated database
-- Live proxy requests show unchanged responses. TBD: a Python-side real-PostgreSQL test harness
-
-### Rollback
-
-- Roll back the release, never retry an uncertain native write through Prisma
-
-### Out of scope
-
-- SQLx owning schema migrations, and removing Prisma
-- Converting unrelated routes to dependency injection

-The `integration` workflow on `main` runs from a scheduled pipeline in the CircleCI project settings, cron `9 0-8,14-23 * * *` (UTC) on `main` with no pipeline parameters. It has no `triggers:` block in this file because a workflow with one runs only on its schedule, so the API pipelines that set `run_migration_tests` or `routing_parity_base` would stop running it. If main stops getting integration runs, check that the schedule still exists and recreate it with these values
-
-Jobs clone with the `checkout_over_https` command, never the built-in `checkout` step, because CircleCI falls back to the project's SSH checkout key without its GitHub App access, GitHub rejects that key, and the public repo needs no key. It fetches the job's commit with full history and no file contents (`--filter=blob:none`), like the built-in step did, so `scripts/path_filter.sh` can find a merge base
-
-A step that checks out files from another commit fetches that commit with `--no-filter`, as `routing_parity` does, because the clone has no file contents and git would otherwise download each missing file in its own request, which took 210 to 896 seconds for the routing parity base

-     Drop every section you have nothing to put in, heading included: a bare "## Relevant issues" or

-## Handwritten 1-3 sentence description

-     An AI agent may draft a starting point here, but always wraps its draft in the make-me-human-readable tags below,
-     backticks included so the tags stay visible on GitHub, so nobody mistakes it for the author's words. The author rewrites it in their own words and deletes the tags.

-## TLDR
-
-<!-- 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 -->

-
-## User Flow
-
-<!-- Two ordered lists, Before and After, walking the same end user through the same task, written strictly from that user's seat
-     Read the linked issue, ticket, or customer thread first so the flow reflects the real application and the routes its users actually hit; don't invent a generic scenario
-     Lead each list with one plain sentence saying where the flow fails (Before) or succeeds (After), then number the steps
-     Keep it tight: aim for 3 to 5 steps per list, one line each, roughly 20 words max, and never pad a shorter flow with filler steps to hit the count. Cover the one path the PR changes and fold variants (case, other field, second endpoint) into a clause on the step they belong to rather than their own steps. The example below is the target length
-     Every step is something the user does or observes: the HTTP method and full URL they hit, what they sent, and what visibly came back (status code, error text, the shape of an ID). UI steps name the page URL and what is on screen
-     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, 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
-
-Example:
-
-Before: a developer whose app streams chat completions gets no token counts back, so their cost dashboard reads zero
-
-1. They send POST https://litellm-domain/v1/chat/completions with `"stream": true` and no `stream_options`
-2. The last SSE chunk arrives with `"usage": null`, so their app records 0 prompt and 0 completion tokens
-3. They open https://litellm-domain/ui/?page=logs and see the request logged at $0 spend
-
-After: the same request comes back with real token counts, so the dashboard shows real spend
-
-1. The proxy admin sets `always_include_stream_usage: true` and restarts the proxy
-2. The developer sends the same POST https://litellm-domain/v1/chat/completions with `"stream": true` and no `stream_options`
-3. The last SSE chunk now carries a `usage` object with real prompt and completion token counts
-4. https://litellm-domain/ui/?page=logs shows that request at non-zero spend

-## Relevant issues
-
-<!-- e.g., "Fixes #000". Drop the section if there is none -->
-
-## Affected release
-
-<!-- Only for a fix to a regression in a released or rc version (perf, memory, crash, or behavior): name the version it regressed in, e.g. "regression in v1.100.0" or "since v1.101.0-rc.1". Add the `backport-stable` label only when the regression is a P0, meaning its Linear ticket is Urgent (a security hole however narrow, data loss, or a crash or outage for every user on that version), because every labeled PR must be cherry-picked onto the baking rc line before the stable can be tagged; every other regression fix ships in the next rc unlabeled. Drop the section otherwise -->
-
-## 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, drop the section rather than guessing -->
-
-## Pre-Submission checklist
-
-**Please complete all items before asking a LiteLLM maintainer to review your PR**
-
-- [ ] I have added meaningful tests
-- [ ] The handful of test files covering my change pass locally, e.g. `uv run pytest tests/unit/<your_test_file>.py -v`. Leave the suites (`make test-unit-*`, `make test-unit`) to CI: it finishes in ~15 minutes where a laptop takes an hour or more
-- [ ] My PR passes all required CI/CD checks (e.g., lint, schema.d.ts sync check, etc.)
-- [ ] My PR's scope is as isolated as possible; it only solves 1 specific problem
-- [ ] Every automated review on my PR's latest commit has finished, and I have addressed or replied to each of its findings before requesting a maintainer review
-
-## 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
-     Simple PR exception (2026-10-28, #49030). A mechanical change fully proven by focused checks may skip before/after e2e. Follow AGENTS.md's eligibility rule, trace callers, and verify bug-fix regression sensitivity. Record E2E exception at <tip SHA>, scope, rationale, commands and results here. Tests/static checks suffice only for this exception. Keep CI and bot gates, reassess changed diffs, and honor explicit e2e requests. Omit the Before/After scaffold for an exception
-     Otherwise proof must be fully e2e, no mocks, with real provider calls where applicable. Pytest alone is insufficient. The following format applies to live proof
-     Show only the latest proof. Before uses the merge base and After the tested tip. Rerun affected QA after behavior changes. Verified neutral diffs may carry proof with the tested SHA, current tip, equivalence reason and focused checks, following AGENTS.md and /qa
-     Use matching Before/After case headings with numbered commands and observed output. Put shared setup above them. For one case, omit case headings
-
-### Before (<hash>)
-
-#### <case 1>
-
-1. ...
-2. ...
-
-#### <case 2>
-
-1. ...
-
-### After (<hash>)
-
-#### <case 1>
-
-1. ...
-2. ...
-
-#### <case 2>
-
-1. ...
-
-     For bug fixes: Before shows the reproduction, After shows the same steps passing
-     For new features: Before shows the capability missing, After shows it working end-to-end
-     If the change applies to all three LLM endpoints (/v1/responses, /v1/chat/completions, /v1/messages), make each endpoint its own case, not just one
-     For UI changes: before/after screenshots under the same headings
-     If the main use case runs through a coding tool like Claude Code or Codex, drive that tool interactively the way the user does (never `claude -p`, `codex exec`, or curl on its own) and embed before/after screenshots of its pane under the same headings; curl replays and headless runs can follow as extra cases, never as the only proof -->

-## Caveats (if any)
-
-<!-- Group caveats under severity subheadings (### Severe, ### High, ### Medium, ### Low), with
-     short bullet points inside each, just like the TLDR: one line per bullet, roughly 10 words max
-     Call out known limitations, follow-up work, or anything a reviewer should watch out for
-     Include only the tiers that have caveats; drop the empty ones
-     - Severe: inherent to what the PR deliberately ships, there even when the code works as intended:
-       it can degrade or take down a running deployment (e.g. a slow or table-locking boot migration),
-       rewrite data by design, break an existing workflow on purpose, or change auth behavior. An
-       operator must plan around it before rollout
-     - High: an unintended hole: a correctness, security, data-loss, or backward-compatibility bug,
-       unsafe to ship as is
-     - Medium: a real gap someone can hit, but with a workaround or a narrow blast radius
-     - Low: anything else worth noting: naming, cleanup, an edge case nobody hits
-     Nest bullets as deep as helps: hierarchy beats one long line when it makes things clearer to a
-     human reader
-     If you assumed something instead of testing it, e.g. "only reproduces with X on" or "no
-     user-observable behavior difference", list it here too with what breaks if it is wrong
-     Drop this section if there are none -->
-
-## 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 $LITELLM_MASTER_KEY" -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

+<!-- The whole description's target audience is humans, not AI agents: write it in plain, simple,
+     everyday engineering language, extremely parsable and readable at a glance. This goes double for
+     the TLDR, User Flow, and Caveats sections
+     Drop every section you have nothing to put in, heading included: a bare "## Relevant issues" or
+     "## Affected release" with nothing under it must not appear in the final description -->
+
+## TLDR
+
+<!-- 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 -->
+
+Problem this solves:
+
+- <blah>
+- ...
+
+How it solves it:
+
+- <blah>
+- ...
+
+## User Flow
+
+<!-- Two ordered lists, Before and After, walking the same end user through the same task, written strictly from that user's seat
+     Read the linked issue, ticket, or customer thread first so the flow reflects the real application and the routes its users actually hit; don't invent a generic scenario
+     Lead each list with one plain sentence saying where the flow fails (Before) or succeeds (After), then number the steps
+     Keep it tight: aim for 3 to 5 steps per list, one line each, roughly 20 words max, and never pad a shorter flow with filler steps to hit the count. Cover the one path the PR changes and fold variants (case, other field, second endpoint) into a clause on the step they belong to rather than their own steps. The example below is the target length
+     Every step is something the user does or observes: the HTTP method and full URL they hit, what they sent, and what visibly came back (status code, error text, the shape of an ID). UI steps name the page URL and what is on screen
+     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, 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
+
+Example:
+
+Before: a developer whose app streams chat completions gets no token counts back, so their cost dashboard reads zero
+
+1. They send POST https://litellm-domain/v1/chat/completions with `"stream": true` and no `stream_options`
+2. The last SSE chunk arrives with `"usage": null`, so their app records 0 prompt and 0 completion tokens
+3. They open https://litellm-domain/ui/?page=logs and see the request logged at $0 spend
+
+After: the same request comes back with real token counts, so the dashboard shows real spend
+
+1. The proxy admin sets `always_include_stream_usage: true` and restarts the proxy
+2. The developer sends the same POST https://litellm-domain/v1/chat/completions with `"stream": true` and no `stream_options`
+3. The last SSE chunk now carries a `usage` object with real prompt and completion token counts
+4. https://litellm-domain/ui/?page=logs shows that request at non-zero spend
+-->
+
+## Relevant issues
+
+<!-- e.g., "Fixes #000". Drop the section if there is none -->
+
+## Affected release
+
+<!-- Only for a fix to a regression in a released or rc version (perf, memory, crash, or behavior): name the version it regressed in, e.g. "regression in v1.100.0" or "since v1.101.0-rc.1". Add the `backport-stable` label only when the regression is a P0, meaning its Linear ticket is Urgent (a security hole however narrow, data loss, or a crash or outage for every user on that version), because every labeled PR must be cherry-picked onto the baking rc line before the stable can be tagged; every other regression fix ships in the next rc unlabeled. Drop the section otherwise -->
+
+## 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, drop the section rather than guessing -->
+
+## Pre-Submission checklist
+
+**Please complete all items before asking a LiteLLM maintainer to review your PR**
+
+- [ ] I have added meaningful tests
+- [ ] The handful of test files covering my change pass locally, e.g. `uv run pytest tests/unit/<your_test_file>.py -v`. Leave the suites (`make test-unit-*`, `make test-unit`) to CI: it finishes in ~15 minutes where a laptop takes an hour or more
+- [ ] My PR passes all required CI/CD checks (e.g., lint, schema.d.ts sync check, etc.)
+- [ ] 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 actual LLM calls costing real $$$ if applicable. `pytest` commands are not enough
+     Show ONLY the latest run: capture Before at the merge base and After at the PR's current tip, and when new commits change behavior, replace this whole section with the fresh run instead of stacking it on top of older ones. The run must be up to date. As soon as a new commit is made and it makes this PR description's after sha stale (it's no longer tip of PR), you must re-run the QA
+     Structure the section exactly as below: Before and After one heading level below this section, each naming the commit hash it was captured at, one lower-level heading per case inside each, the same case names in the same order on both sides, and numbered steps (command, observed output) under every case, never loose prose; shared setup (config, payloads) goes above Before, and with a single case, drop the case headings and number the steps directly
+
+### Before (<hash>)
+
+#### <case 1>
+
+1. ...
+2. ...
+
+#### <case 2>
+
+1. ...
+
+### After (<hash>)
+
+#### <case 1>
+
+1. ...
+2. ...
+
+#### <case 2>
+
+1. ...
+
+     For bug fixes: Before shows the reproduction, After shows the same steps passing
+     For new features: Before shows the capability missing, After shows it working end-to-end
+     If the change applies to all three LLM endpoints (/v1/responses, /v1/chat/completions, /v1/messages), make each endpoint its own case, not just one
+     For UI changes: before/after screenshots under the same headings
+     If the main use case runs through a coding tool like Claude Code or Codex, drive that tool interactively the way the user does (never `claude -p`, `codex exec`, or curl on its own) and embed before/after screenshots of its pane under the same headings; curl replays and headless runs can follow as extra cases, never as the only proof -->

+
+🆕 New Feature
+🐛 Bug Fix
+🧹 Refactoring
+📖 Documentation
+🚄 Infrastructure
+✅ Test
+
+## Caveats (if any)
+
+<!-- Group caveats under severity subheadings (### Severe, ### High, ### Medium, ### Low), with
+     short bullet points inside each, just like the TLDR: one line per bullet, roughly 10 words max
+     Call out known limitations, follow-up work, or anything a reviewer should watch out for
+     Include only the tiers that have caveats; drop the empty ones
+     - Severe: inherent to what the PR deliberately ships, there even when the code works as intended:
+       it can degrade or take down a running deployment (e.g. a slow or table-locking boot migration),
+       rewrite data by design, break an existing workflow on purpose, or change auth behavior. An
+       operator must plan around it before rollout
+     - High: an unintended hole: a correctness, security, data-loss, or backward-compatibility bug,
+       unsafe to ship as is
+     - Medium: a real gap someone can hit, but with a workaround or a narrow blast radius
+     - Low: anything else worth noting: naming, cleanup, an edge case nobody hits
+     Nest bullets as deep as helps: hierarchy beats one long line when it makes things clearer to a
+     human reader
+     If you assumed something instead of testing it, e.g. "only reproduces with X on" or "no
+     user-observable behavior difference", list it here too with what breaks if it is wrong
+     Drop this section if there are none -->
+
+## 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

+# Semantic matrix: each shard groups tests by concern (auth, server, logging, …)
+# rather than alphabetical letter ranges. Adding a new test file means adding it
+# to whichever group it belongs to, not reshuffling slices.
+#
+# `.circleci/tests.yml` runs each group's files on same-repo events under the
+# `proxy-db-<group>` Codecov flag; `.circleci/scripts/unit_selection.sh` holds
+# the file lists. That pipeline is manual-only while the tests migrate, so
+# `unit-flag` makes the shard run that list on every event. `test-path` keeps
+# the files that still reach real providers and never left
+# tests/proxy_unit_tests.
+#
+# Design targets:
+#   * Every shard runs in <= 7 minutes of wall-clock on the default runner.
+#     Most of a shard's time is pytest plugin load + xdist worker imports +
+#     pytest-cov instrumentation, not the tests themselves. Keeping per-shard
+#     work low and matching worker count to runner cores is what controls it.
+#   * `timeout` bounds the pytest step only. Checkout, dependency install, and
+#     Prisma client generation draw on a separate allowance in the base
+#     workflow, so slow setup shows up as a slow job rather than as a
+#     cancelled shard whose tests were passing.
+#   * workers: 4 matches the 4-core ubuntu-latest runner. -n 8 on 4 cores
+#     oversubscribes 2x and workers fight for CPU during their cold-start
+#     imports (measured ~441% CPU for -n 8 locally, i.e. ~55% effective).
+#   * test_key_generate_prisma.py stays serial (workers=0) — it has event-loop
+#     conflicts with the logging worker when run in parallel.
+#   * test_proxy_utils.py runs as a single shard with --dist=worksteal so
+#     xdist balances its 188 parametrized cases across workers instead of
+#     pinning the whole file to one worker (the default --dist=loadscope
+#     behavior for single-file targets).

 `tests/unit/` mirrors `litellm/` in a parallel path (see `tests/unit/AGENTS.md`). Name tests `test_<filename>.py`, but always match the existing test file in the directory you touch — many provider dirs use longer descriptive names (e.g. `test_anthropic_chat_transformation.py`) to avoid ambiguity across sibling folders. For bug fixes, extend the existing mapped test file rather than creating a new one. Only create a new test file for a new feature (provider, endpoint, or transformation module) that has no mapped test yet, following that directory's naming convention (or `test_<filename>.py` if you're the first test there). One focused regression test beats many shallow ones
 
-End-to-end tests belong in `tests/e2e/`. A rule about one directory's files, like its harness or which CI runs it, goes in that directory's `AGENTS.md`, never only in a README or here. Read a directory's `AGENTS.md` before editing files in it
-
-Before you build a new way to move data between the endpoints, the provider transformations, and cost tracking or logging, read the architecture decision records in `docs/adrs/`, which say why those layers are shaped the way they are

Check that two worker PIDs are serving, and use the same worker count and Redis setup for the before and after proof. When the PR is about `--run_gunicorn`, `--run_hypercorn`, or `--run_granian`, which `--reload` does not support, drop `--reload`. When it is about behavior without Redis, drop Redis. When the proxy prints `"workers" flag is ignored when reloading is enabled`, that checkout or its uvicorn reloads only one worker, so drop the two-worker check for it.

-Simple PRs may skip before/after e2e when the full diff is mechanical and focused checks completely prove it, such as #49030 restoring an existing helper name. Trace affected callers and run relevant tests/static checks at the tip. For a bug fix, establish that the regression catches the original defect. Size alone never qualifies. New behavior, API/provider semantics, auth, billing, persistence, concurrency or uncertain integration risk need live e2e. In Screenshots / Proof of Fix, record `E2E exception at <tip SHA>`, scope, rationale, commands and results. Tests count as proof only for this exception. Reassess changed diffs, retain CI/bot gates, and honor explicit e2e requests (2026-10-28, unnecessary live QA for #49030)
-
-For other PRs, proof must show the end user's real flow before and after, with commands and output against a live proxy and real provider calls where applicable. Pytest alone is insufficient. For UI or interactive coding-tool flows, drive that surface and embed before/after screenshots, with URLs, clicks and input fields a reviewer can reproduce
+Never use `pytest` commands or the like as "Screenshots / Proof of Fix". We prefer curl'ing a live proxy instance running on localhost:4000 (I like to run it with `python litellm/proxy/proxy_cli.py --config litellm/proxy/dev_config.yaml --detailed_debug --reload --use_v2_migration_resolver 2>&1 | tee litellm.log`; the Admin UI dev server is `npm run dev` in `ui/litellm-dashboard`, served on port 3000) and showing both the command run and the output. Also, it should hit real LLM provider APIs, not mocks, and cost real $$$ because that is the most realistic test. The proof of fix should be exactly what the end user / customer would see / do. The run logs in PR #27703 is a prime example of how to do it (not a huge fan of using a python test script that future me and the team will have no visibility into; I prefer just curl commands or a short list of bash commands (e.g., using `for`)). If it's a UI thing, or the main use case runs through a headful agentic coding tool like Claude Code or Codex, drive that surface yourself and embed your own before and after screenshots of it in the PR (the Admin UI page, or what the coding tool shows), next to an ordered list of the URLs to go to (e.g., http://localhost:4000/ui/?page=logs), where to click, and what fields to fill out so a reviewer can reproduce it
 
 If you ever write any human-facing text (pull requests, issues, commit messages, discussion posts, github comments, release notes, docs, etc.), always follow these guidelines to sound less AI-y:
 - don't use emojis
-- don't use "—". Don't use ";" or ":" unless it would be nonsensical not to. Instead, reach for ",", ".", conjunction words, etc. in descending order of preference: vary among them, weighted toward the front of the list, and skip "," where it would cause a comma splice or the sentence is getting long. Overusing any one of them also feels AI-y. A word cap does not penalize you for adding more sentences

Overusing any one of them, ";" especially, also feels AI-y. A word cap does not penalize you for adding more sentences: when writing under tight word budgets, prefer a period split or a conjunction over ";", and keep to at most one ";" per message
 - don't use the pattern "It's not X, it's Y", "You're not X, you're Y", etc.
 - unless explicitly asked, don't use bulleted or numbered lists unless it would be nonsensical not to. Instead, prefer prose
-- don't add a trailing "." at the end of paragraphs (just like this file). That means every paragraph, not just the last one (of the markdown file, PR description, GitHub comment, etc.). Rule of thumb: if you're adding new line(s) before the next sentence, don't add a ".". Exception is that docs (i.e., litellm-docs) should have trailing "."

-The five lint gates (`scripts/ruff_strict_gate.py`, `scripts/type_discipline_gate.py`, `scripts/test_quality_gate.py`, `scripts/openapi_docs_gate.py`, `scripts/type_check_gate.py`) compare each rule's codebase count on your branch against the count at its merge-base with the default branch, and a rule may not grow. There are no budget files to edit or ratchet: when a gate fails, fix the violations the branch introduced or remove at least as many of that rule elsewhere in the tree. The one exception is `reportAny` / `reportExplicitAny`, which share a fixed codebase-wide cap in `ANY_CAPS` in `scripts/type_check_gate.py` because Any spreads past the lines you touch. A branch may add Anys while the total stays under that cap. Only lower `ANY_CAPS`, and only in its own PR to the default branch, never raise it on a feature branch
+Never edit or commit `ruff-strict-budget.json`, `type-discipline-budget.json`, `basedpyright-code-budget.json`, or `test-quality-budget.json` on a PR branch, and don't run `make lint-budget-update` there. A scheduled Devin automation lowers the limits on the default branch in its own PR by exactly what landed since the last ratchet, so concurrent PRs don't fight over the same `"limit"` lines. Keep the hosted automation's target in sync when the repository default changes. If your branch already carries a budget edit, drop it before opening the PR
 
 `make check` (f.k.a. `make pre-commit`, which still works identically as an alias) saves its complete output to a log file in .git (overwriting previous logs) and prints that path as its first and last output lines. To inspect a run, read or grep that log instead of re-running the multi-minute checks just to see a different slice
 
-`make check`, `make lint`, `scripts/pre_commit_lint.sh`, and the standalone lint gates (`scripts/ruff_strict_gate.py`, `scripts/type_discipline_gate.py`, `scripts/type_check_gate.py`) each hold one of 2 machine-wide slots, so when other sessions or worktrees on the same box are already running heavy work, yours prints "all N machine-wide slots are busy" followed by "queueing" and then stays quiet until a slot frees.

-If you get an LIT001 fail, refactor the code to follow functional programming best practices rather than introducing mutable data structures. For example, build values in one shot with comprehensions or generators wrapped in `tuple()` / `MappingProxyType()` / `frozenset()` instead of seeding an empty `list`/`dict`/`set` and mutating it over time. Ideally, `# mutable-ok` is never used. Reach for it only as a genuine last resort when an immutable rewrite is truly impossible, and always pair it with a real reason

 Every lint or type suppression must name the exact rule inside brackets and carry a reason comment, e.g. `# pyright: ignore[reportArgumentType]  # stubs lack async overload` or `# noqa: TID251  # <reason>`. `# type: ignore` is banned (LIT009): pyrightconfig.json sets `enableTypeIgnoreComments` to false, so it silently does nothing

 Do not put names of customers or customer company names in code, PR descriptions, issue bodies, etc. This means never mention literally any company name. Especially if you're about to say a sentence mentioning that the reason the PR exists was a feature/model/bug fix/etc. requested by a company. That's the indication that you should replace that company name with "the customer". e.g. not "Model request from Acme (Pylon #1234)" but "Model request from a customer (Pylon #1234)". This is because the codebase is public. The only exception is for publicly known providers or vendors such as OpenAI, Anthropic, AWS Bedrock, etc. only IF we're adding support for that provider/vendor in general and NOT if that PR or whatnot was a request by one of them, and they're actually one of our customers.

 Prisma migrations apply synchronously at proxy boot, before it serves traffic, so a migration must only change schema, never rewrite rows. No `UPDATE`, `DELETE` or `MERGE`, and no `INSERT ... SELECT`: on a spend-log-sized table any of those is minutes of downtime plus a doubled heap that plain autovacuum won't give back. `tests/code_coverage_tests/check_migrations_no_data_rewrites.py` enforces this. When a rewrite is genuinely bounded and has to ship inside the migration, mark the statement `-- data-migration-ok: <what bounds it>`
