-metadata:

-# 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

 `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

 If you're resolving a linear ticket, in the "## Linear ticket" section of the PR, say "Resolves LIT-1234", replacing "LIT-1234" with the actual ticket id that you're resolving. If you don't have the ticket id, don't make one up or search for it. Just drop the section

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. Say in the proof which part you dropped and why

-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 "."

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)".

-## Proving Your Change Works End to End
-
-Tests are required, but they do not prove that your change works for a user. A PR that changes what the proxy or SDK does shows a real run in its "Screenshots / Proof of Fix" section, meaning the exact commands you sent to a live proxy and the output that came back, against real provider APIs and not mocks. `pytest` output does not count as proof, because a passing test only shows that the code does what its mocks expect. A PR that changes only docs or CI shows the rendered page or the CI run instead
-
-A good proof looks like this:
-
-1. Install the proxy dependencies with `make install-proxy-dev`, then start the proxy from your branch with a config that has the model you changed, `uv run litellm --config your_config.yaml --detailed_debug`
-2. Send the request a user would send with `curl`, and paste both the command and the response. When cost or routing is involved, include the response headers, since `x-litellm-response-cost` is what the user sees
-3. For a bug fix, do this twice, once at the merge base with BerriAI/litellm's main (`git merge-base origin/main HEAD`, with your remote for BerriAI/litellm in place of `origin` in a fork clone) to show the bug and once at your branch's latest commit to show the fix. Name both commit hashes
-4. If your change is reachable from more than one endpoint (`/v1/chat/completions`, `/v1/responses`, `/v1/messages`), show each one
-5. If the request can stream, show a `"stream": true` run too, because streaming builds usage and cost on a different path. A stream sends its headers before its usage exists, so show the `usage.cost` on the last chunk, which `/v1/chat/completions` sends when the request has `"stream_options": {"include_usage": true}` and other endpoints send with `include_cost_in_streaming_usage: true` under `litellm_settings`, or, when the proxy has a database, the request's row on the Admin UI's Logs page or `GET /spend/logs`
-6. For UI changes, add before and after screenshots and name the page
-7. If users reach your change through a coding tool such as Claude Code or Codex, drive that tool the way a user does and add before and after screenshots of it, because a `curl` or a headless run alone does not show what the user sees

-## Contributing an LLM Provider Integration
-
-Provider work (a new provider, a new parameter, a new usage or cost field) is the most common kind of contribution, and it is where PRs get reworked most often. Follow these rules
-
-**Preserve zero prices.** In [`model_prices_and_context_window.json`](model_prices_and_context_window.json), an explicit `0.0` means that the priced operation is free. A missing field or `null` means no rate is specified, so the relevant calculator may use a fallback. For example, when no batch input rate is configured, batch cache writes use `cache_creation_input_token_cost` if set, otherwise the regular input rate, then apply the batch discount. A zero ordinary input rate does not make separately priced cache reads or writes free. Test `rate is None` before substituting a fallback, since `row.get("cache_creation_input_token_cost") or fallback` would discard a valid zero. Speech keeps character pricing ahead of token pricing even when the character rate is zero. If neither rate is configured, speech cost calculation raises an error. Its model lookup preserves unset rates instead of treating compatibility defaults as explicit zero prices. Perplexity keeps a configured legacy search rate ahead of the current search rate, including zero. When registering custom prices, `None` leaves an existing rate unchanged and `0.0` overrides it
-
-**Find the existing machinery before you add plumbing.** LiteLLM already has generic paths that move data between the endpoints, the provider transformations, and cost tracking. A second, hand-rolled path for the same data is a common reason a provider PR gets rewritten before merge. [`ARCHITECTURE.md`](ARCHITECTURE.md) shows where the layers live, and the decision records in [`docs/adrs/`](docs/adrs/AGENTS.md) explain why they are shaped that way. For example, [the ADR on provider usage fields](docs/adrs/adr_001_provider_usage_fields_ride_as_usage_extras.md) covers how provider-specific usage fields reach cost tracking. If you cannot find a mechanism for what you need, say so in the PR or ask in [#pr-review on Slack](https://join.slack.com/t/litellmossslack/shared_invite/zt-3o7nkuyfr-p_kbNJj8taRfXGgQI1~YyA) before you build one
-
-**Bill a new provider usage field from the usage object.** Leave the field on the usage object as an extra and read it in that provider's `cost_calculator.py`. A provider without one gets a new `cost_calculator.py` and an arm for it in `cost_per_token` (`litellm/cost_calculator.py`), which picks the calculator by provider. If the provider's transform builds `Usage` from named fields, as the Anthropic, Gemini, and Bedrock Converse ones do, pass the new field there too. Streamed requests rebuild usage in `ChunkProcessor.calculate_usage` (`litellm/litellm_core_utils/streaming_chunk_builder_utils.py`), which does not copy extras yet the way the Responses-to-chat bridge does (minus a short exclusion list), so until it does, bill the field on streams by naming it there, as Anthropic's `inference_geo` is. A provider that reports its own charge for the request, as OpenRouter does in `usage.cost`, is billed at that charge from `_hidden_params` before any calculator runs, unless the deployment sets its own prices. When the field counts a built-in tool such as web search, add the provider to `get_cost_for_web_search_request` in `litellm/llms/__init__.py`, and add a gate to `litellm/litellm_core_utils/llm_cost_calc/tool_call_cost_tracking.py` only when no existing gate fires. Then show the field's cost in your proof on every endpoint it reaches, streaming included
-
-**Do not change what a caller sees to make internals easier.** Each endpoint keeps the schema of the API it emulates. A `/v1/responses` caller gets `input_tokens` and a `/v1/chat/completions` caller gets `prompt_tokens`, whatever the provider sent and whatever cost tracking needs. A provider usage field that shows up as an extra key is fine, since it only adds a key, but renaming, removing, or reshaping a key the endpoint defines is not. Reshaping a public response to feed an internal consumer breaks every user of that endpoint
-
-If your change makes an architecture decision, such as a new cross-cutting mechanism or a deliberate difference from a provider's API shape, add an ADR to [`docs/adrs/`](docs/adrs/AGENTS.md) in the same PR
