+# Response cache foundation
+
+`ResponseCache<B>` adds request keys, independent read/write controls, response envelopes, and freshness checks to any `B: BaseCache<Value = CacheEntry>`
+
+## Ownership
+
+`litellm-cache` defines typed storage and codec traits. Memory and Redis implement those traits without depending on response policy. Other consumers can store their own value types using the same backend implementations
+
+`litellm-cache-response` owns response keys, controls, entries, the Python-compatible response codec, and `WriteBuffer`, the backend-neutral deferred-write policy. It has no runtime dependency on a specific cache backend or Python
+
+The Python bridge constructs backends and selects them through its private `NativeResponseCache` enum, which only dispatches. Generic Rust callers inject their backend directly. A native gateway can construct the same generic response service in its own host
+
+## Native Rust use
+
+```rust
+use std::{sync::Arc, time::Duration};
+use litellm_cache_memory::InMemoryCache;
+use litellm_cache_response::{CacheKeyInput, ResponseCache, ResponseCacheRequest};
+use serde_json::json;
+
+let cache = ResponseCache::new(Arc::new(InMemoryCache::default()));
+let request = ResponseCacheRequest::new(CacheKeyInput {
+    preset: Some("example:key".into()),
+    ..Default::default()
+});
+let now = Duration::from_secs(100);
+cache.store(&request, json!({"answer": 7}), now)?;
+assert_eq!(cache.async_lookup(&request, now).await?, Some(json!({"answer": 7})));
+```
+
+For Redis, inject `RedisCache::new(url, ttl, ResponseCacheCodec)` instead. Namespaces are optional and existing namespace prefixes are preserved. Sync operations check out independent connections from a bounded pool, while async callers, including counters and claims, move that blocking work off the executor. The pool skips the checkout PING and instead discards any connection whose command failed
+
+Callers supply Unix time for response freshness. Backend TTL uses its own clock. A read can reject an entry through `max_age` even while the backend still retains it
+
+## Python integration boundary
+
+The extension keeps a private test harness for memory and Redis single and batch response lookup and storage. Batch lookup returns ordered values plus missing indices for embedding partial-hit wiring. No bridge-only cache type is part of the public API
+
+The bridge also exposes a production-shaped response cache runtime selected through the Rust catalog. Its shipped rule set is empty, so current SDK, Router, and proxy calls stay on Python and do not construct native cache resources. Tests can inject a rule and build the native memory runtime from an ordinary Python `Cache` configuration without changing the legacy cache classes
+
+Object responses are written as they are, and every other response shape is written as a serialized string, which is the pair of shapes Python reads. A string on the wire is therefore always a serialized response, so string-valued responses round trip. Typed backends such as memory never pass through the codec
+
+The resolver reads the namespace's `cache` attribute each time it resolves. A captured binding retains the selected service for its operation, including background writes. `None` disables caching. Custom Python cache objects keep their original methods, arguments, returned awaitables, exceptions, and caller-task execution
+
+Python callbacks use the built-in `Cache` API, so a `Cache` subclass works unchanged. A batch lookup takes one original kwargs mapping per request and returns the list of `get_cache` or gathered `async_get_cache` results, while native bindings return `{values, missing_indices}`. A batch store hands the caller's original result to `async_add_cache_pipeline`. `ping` calls `ping`, and a flush goes to the facade's backend
+
+The private facade test harness checks object identity, method overrides, effective TTL, Redis namespace, memory capacity, and later configuration changes before selecting native execution. Its snapshot includes Redis connection settings, so a later `redis_kwargs` change, including an SSL option, selects Python callback execution. Buffered async writes honor `redis_flush_size`. Public activation must construct the shared native service from the initial Python Redis settings, including `litellm.default_redis_ttl` and SSL options. A buffered entry keeps the time it was produced, and a failed flush drops its batch instead of growing the buffer during an outage. The harness does not migrate entries or replace Python methods. Until activation configures one shared service, the Python facade and native test service can hold separate data. Existing public cache constructors remain on Python
+
+Native cache handles must be recreated after fork. The bridge releases the GIL around native operations, and Redis runs blocking connection operations off the async executor. Native errors propagate to the host, which owns the existing fail-open and logging policy
+
+The Redis backend also provides the primitives needed to preserve its direct Python surface later: TLS URLs, ping, bulk delete, counter batches, TTL, scan, set membership, raw queue push and pop, queue and counter pipelines, counter floor and maximum operations, script evaluation, client information, namespaced flush, and full flush. These are backend operations only and are not exported to Python by this PR. Memory provides TTL, oldest-key, and counter-pipeline operations
+
+## Adding another backend
+
+Implement `BaseCache` for the backend with its associated value type, and accept a `CacheCodec` when wire serialization is needed. `ResponseCache<B>` then works without another response implementation. Add a concrete bridge enum variant and constructor only when exposing that backend to Python
+
+Verify typed values, TTL precedence, missing entries, serialization failures, namespaces, batch ordering, and sync/async behavior. Run response fixtures with `ResponseCacheCodec`, including both Python envelope encodings, before enabling a public facade
+
+## Follow-up scope
+
+Public SDK, Router, and proxy activation still need constructor parity, stream replay, embedding partial-batch integration, response reconstruction, callback scheduling, and failure-policy integration. This foundation does not switch those request paths
+
+Redis cluster, disk, and cloud stores remain follow-ups. Semantic backends plug in through `SemanticCacheContext`, which carries the prompt inputs and metadata alongside the cache TTL. The generic dual cache takes read, write, and remote-failure policies, runs its async operations through the async L2 methods, and provides L2-first counters and atomic affinity claims. Errors propagate by default, and `RemoteFailurePolicy::UseLocal` opts key-value operations and claims into the local tier when L2 is unavailable. Claims compare decoded values, so a pin written by Python still matches. Public Router integration remains follow-up work. Reservations and pubsub still need explicit capabilities owned by their consuming features. Adding a cache backend does not establish those guarantees

+Native OCR uses `SecretSource` with `EnvironmentSecrets`, preserving process-environment reads. Readable Python secret managers still make OCR decline to the existing Python implementation. `ResolvedSecrets` and the separate `secret_manager_binding()` snapshot are inactive foundations for a later rollout
+
+Cache and secret-manager catalog entries remain Python-only, including when `LITELLM_RUST=1`. The new cache runtime is not connected to SDK or gateway caching
+
+OCR provider requests use the shared `litellm-http` pool. AWS and Google secret-manager SDK clients keep their SDK transports, which do not yet inherit the pool's proxy, TLS, certificate, timeout, or observability configuration. Preserve those SDK transports and configure them equivalently instead of forcing them through reqwest

+# Secret resolution
+
+Construct `SecretManagerState::new(backend, settings)` for a configured manager or use `SecretManagerState::default()` for environment lookups. The configured backend determines its provider identity. Write-only settings and names excluded by `hosted_keys` use the environment directly. `secret_manager_would_be_consulted` follows the same routing decision as resolution
+
+`get_secret` returns `Ok(Some(value))` for a found value, `Ok(None)` when no source contains the value, and `Err(error)` when lookup fails. For managed names, resolution checks the manager, then the environment, then the caller's default. An empty string, `false`, or an explicitly stored JSON null is a found value
+
+Backend failures propagate by default. To allow fallback during a backend failure, construct the resolver with `.with_failure_policy(FailurePolicy::EnvironmentFallback)`. It then tries the environment and default, in that order. If neither exists, the original error is returned. This policy applies to manager lookups. Explicit OIDC references retain their own authentication errors and never fall back to environment secrets under the reference name
+
+`get_secret` preserves value types. `get_secret_str` accepts a string default and rejects boolean or JSON values with `Error::TypeMismatch`. `get_secret_bool` accepts a boolean default and converts strings containing `true` or `false`, ignoring surrounding whitespace and ASCII case. Other strings and JSON values produce `Error::TypeMismatch`. Conversion failures never activate fallback or replace a found value with the default
+
+Provider payloads remain strings unless explicitly selecting a field from an AWS primary JSON secret. Google caches only successfully decoded string payloads, so reads have identical values and types before and after caching. Confirmed absence and failed reads are not cached. AWS resource-not-found responses and Google HTTP 404 responses indicate absence. Other provider errors remain errors, and successful responses without the required payload are malformed responses rather than missing secrets
+
+The HashiCorp Vault backend is enabled with the `hashicorp` feature and reads KV v2 values from `HCP_VAULT_*` environment variables. It supports static tokens, AppRole authentication, and TLS certificate authentication

+# Token counting
+
+`Tokenizer` is the text-counting interface. `TextCodec` adds encoding, decoding, and a name. `TokenCounter` applies LiteLLM request, message, and tool accounting using any `Tokenizer`
+
+Counts follow the codec: tiktoken treats special-token spellings as ordinary text, while Hugging Face applies its added tokens, post-processing, padding, and truncation. `fast=True` preserves those semantics and requests acceleration where available. Unsupported configurations use the normal codec, including tiktoken encodings without a scanner and builds without the `fast` feature. Invalid input and process-guard errors still propagate. Runtime request counting currently uses the normal codec; the custom accelerator is retained for explicit use and testing
+
+`FastCounter: TextCodec` exposes an optional accelerator over a loaded codec. `None` means callers should use that codec. The Python bridge caches this selection per immutable tokenizer, shares it with request counters, and initializes it with the GIL released. Hugging Face can also choose the full encoder per input when added tokens require it
+
+The `fast` feature provides `fast::FastTokenizer` from `litellm-token-counter-fast`. `TokenCounter::from_json_fast` uses this implementation
+
+The `huggingface` feature provides `huggingface::HuggingFaceTokenizer` through the upstream `tokenizers` library. `TokenCounter::from_json` uses this implementation
+
+The `tiktoken` feature provides `tiktoken::TiktokenTokenizer` through `tiktoken-rs`. Select an encoding with `TokenCounter::from_tiktoken`. The supported names are `cl100k_base`, `o200k_base`, `o200k_harmony`, `p50k_base`, `p50k_edit`, `r50k_base`, and `gpt2`
+
+All three backends are enabled by default in this crate and the Python extension. With `default-features = false`, Rust callers can supply their own `Tokenizer` to `TokenCounter::new` without compiling a built-in backend
+
+Python `tiktoken` and `tokenizers` remain runtime dependencies and the default implementations. The catalog independently selects the tokenizer and request-counting routes. Enabling Rust changes factory dispatch; existing tokenizer objects keep their backend. Native Hugging Face wrappers provide an immutable encoding and decoding API, while training and mutable configuration remain available through the Python backend
+
+Budget checks, cost calculation, and the `max_tokens` adjustment policy belong to `litellm-core-utils`. The counter does not own prices, budgets, or request limits
+
+Run the feature matrix with:
+
+```sh
+cargo test -p litellm-token-counter
+cargo test -p litellm-token-counter --no-default-features
+cargo test -p litellm-token-counter --no-default-features --features fast
+cargo test -p litellm-token-counter --no-default-features --features huggingface
+cargo test -p litellm-token-counter --no-default-features --features tiktoken

 LiteLLM MCP Client allows you to use MCP tools with LiteLLM
 
+Install the optional dependencies with `pip install 'litellm[mcp]'`, then use the existing public imports:

+from litellm.experimental_mcp_client import call_openai_tool, load_mcp_tools
+from litellm.experimental_mcp_client.client import MCPClient
+
+client = MCPClient(server_url="https://mcp.example.com/mcp")
+```
+
+Core `import litellm` works without the MCP extra. Importing the experimental MCP client without its MCP or HTTPX2 dependency raises an error with this installation command
+
 ## MCP Python SDK compatibility
 
 The `mcp` and `proxy` extras require MCP Python SDK 2.2 or newer within the 2.x release line. Installing core LiteLLM without these extras does not require MCP

 See the official [SDK migration guide](https://py.sdk.modelcontextprotocol.io/migration/) for Python API changes
 
+## Custom HTTP clients and authentication
+
+MCP HTTP and SSE transports now use `httpx2`. Custom authentication passed through `aws_auth` or `resolved_auth` must implement `httpx2.Auth`. Integrations that override the client's HTTP client factory or customize its event hooks must use `httpx2.AsyncClient`, request, response, timeout and transport types
+
+HTTPX1 clients, auth objects and hooks are not adapted by a compatibility shim. Migrate those integrations to HTTPX2 before upgrading. Ordinary `MCPClient` construction and LiteLLM's existing helper imports remain supported; this does not restore SDK1 Python imports or camelCase SDK model attributes in the shared Python environment
+
 ## HTTP redirects
 
 For streamable HTTP POST requests, the MCP SDK follows method-preserving redirects such as HTTP 307/308 within the configured endpoint's origin. Redirects to another path on the same scheme, host and port work. The SDK also permits an HTTP-to-HTTPS upgrade on the same host using the default ports

+Tokenizer factories return Python tokenizer objects by default. Set `LITELLM_RUST=1` or call `litellm.rust(True)` before constructing tokenizers to select the Rust backend through `Route.TOKENIZER` in the Rust catalog. Missing native bindings or unsupported native features fall back to Python. Existing tokenizer objects keep their selected backend. Rust-backed tokenizer objects carry the read-only `tiktoken.Encoding` / `tokenizers.Tokenizer` surface and are immutable: `enable_padding`, `enable_truncation` and `add_tokens` stay on the Python tokenizer.

+    original error surviving only as ``__context__``), so the outage check walks the cause chain, and a
+    missing user falls through to ``no_active_key`` rather than an opaque gateway fault.
     ``source="database"`` reads the row from the database, never the cache, so the credential mint refuses
     a user that a writer deactivated or deleted without evicting the cached row, and it leaves the fresh
     row in the cache for the requests the credential makes next. Every other caller keeps the cache read,

 - **team**: Optional `team_id` argument on `litellm_team`, so teams can be created with a stable, human-readable ID instead of a provider-generated UUID; changing it forces replacement
+- `litellm_jwt_key_mapping` accepts `token_id` as an alternative to `key`, so a

+  of by the plaintext. Exactly one of the two is required. This is what lets a
+  mapping reference a key managed in the same configuration
+  (`token_id = litellm_key.foo.token_id`), which `key` cannot do, because
+  `litellm_key` marks its generated key write-only and referencing it fails at
+  plan time. `POST /jwt/key/mapping/new` and `/jwt/key/mapping/update` gained a
+  matching `token` field, validated as 64 lowercase hex characters so a
+  plaintext key sent by mistake is rejected instead of hashed twice
 - **jwt_key_mapping**: New `litellm_jwt_key_mapping` resource for the proxy's JWT to virtual key mappings, so JWT clients identified by a claim (`client_id`, `azp`, `sub`) map to virtual keys and inherit their models, budgets and rate limits. Supports `description` and `is_active`, rotating the mapped key in place, and forces replacement when the claim name or value changes
 - **team**: `soft_budget`, `tags`, and `soft_budget_alerting_emails` attributes on `litellm_team`, matching what `/team/new` and `/team/update` already accept; `soft_budget_alerting_emails` is sent under `metadata`, where the proxy reads it
 - **user**: New `litellm_user` resource and `litellm_user` / `litellm_users` data sources for managing internal users

The SDKs raise their own typed exceptions on failure, which is exactly the customer-observable contract; management routes (model/key CRUD, spend read-back) and endpoints no official SDK covers (e.g. `/v1/rerank`, `/v1/ocr`, custom passthrough paths) stay on the shared transport.

    Buildkite runs this suite against a Keycloak deployed beside the ephemeral stack by project-releaser. It fetches the realm from the test-runner revision even when it reuses a gateway image from another commit. The GitHub Actions changed-test stack starts the same digest-pinned Keycloak through `.github/e2e-stack/start-idp.sh`, imports the checked-out realm, and exports the IdP URL and credentials in `stack.env`. Both runners configure issuer/audience validation and store the realm, keys and users in a separate schema in the stack's PostgreSQL, so replacing Keycloak preserves token validity. Both wait for realm discovery before running tests. Losing the whole ephemeral database invalidates the stack. Keycloak skips imports into an existing realm, so changes to the realm export require a fresh stack (or deliberately replacing the local data volume). A stack without it fails the JWT tests rather than skipping them

 ### The pull request check
 
-Every same-repository PR that adds, modifies, or renames a `tests/e2e/**/test_*.py` file runs those changed files three times. A change to the harness itself, meaning a root-level `tests/e2e/*.py` file or `pytest.ini`, `tests/e2e/gateway/`, `.github/e2e-stack/`, or the workflow, also runs the `access_control` suite and both JWT suites as canaries, because those files have no test of their own that exercises the stack. `.github/e2e-stack/select_tests.py` applies both rules. The stack config at `tests/e2e/gateway/stage_mirror_ci_config.yml` must declare every model the selected suites use; a missing one shows up as a failed test id in the public log. The suite's own single rerun for network errors and 5xx responses (see `pytest.ini`) applies on every pass, so a transport blip does not fail the check while a race inside a test still does. The stage-mirror stack has a control-plane backend, two gateways behind nginx, Postgres, Keycloak, Jaeger, and TLS cluster-mode Valkey. Realm-only edits also trigger these canaries. The stack exports every gateway address in `LITELLM_PROXY_REPLICA_URLS`, so model registration waits until each gateway lists the new model rather than whichever one the load balancer answered from.

The `ui/`, `claude_code/`, and `load/` directories, `batches/test_managed_files_enforcement_e2e.py`, `llm_translation/realtime/test_realtime_pipecat_audio_e2e.py`, and `guardrails/test_presidio_masking_e2e.py` remain outside this check because they use separate tooling or need a differently configured stack: the pipecat audio suite skips itself at import time unless the NLTK `punkt_tab` data is installed, and the presidio suite fails without the analyzer and anonymizer services this stack does not start. The Redis chaos test under `load/` needs a proxy it can pause the Redis of on the same host (`gateway/redis_chaos_ci_config.yml`), which `.github/workflows/test-e2e-redis-chaos.yml` boots, and which the Buildkite `e2e-redis-chaos` step in project-releaser runs co-located with Postgres and Valkey in one pod; it is deselected unless `E2E_REDIS_CHAOS` is set
+Every same-repository PR that adds, modifies, or renames a `tests/e2e/**/test_*.py` file runs those changed files three times. A change to the harness itself, meaning a root-level `tests/e2e/*.py` file or `pytest.ini`, `tests/e2e/gateway/`, `.github/e2e-stack/`, or the workflow, also runs the `access_control` suite and both JWT suites as canaries, because those files have no test of their own that exercises the stack. `.github/e2e-stack/select_tests.py` applies both rules. The stack config at `tests/e2e/gateway/stage_mirror_ci_config.yml` must declare every model the selected suites use; a missing one shows up as a failed test id in the public log.

The Redis chaos test under `load/` needs a proxy it can pause the Redis of on the same host (`gateway/redis_chaos_ci_config.yml`), which `.github/workflows/test-e2e-redis-chaos.yml` boots, and which the Buildkite `e2e-redis-chaos` step in project-releaser runs co-located with Postgres and Valkey in one pod; it is deselected unless `E2E_REDIS_CHAOS` is set
 
 Every selected file must execute at least one passing test in each pass, and any test failure, collection error, or entirely skipped or deselected file fails the check. A file whose tests are all marked skip therefore cannot pass this check, so unskip at least one of them, or add the file to `UNSUPPORTED` in `select_tests.py` with the reason, before changing one. A failed pass stops the run. The public log prints pytest's one-line summary for each pass, including the rerun count, and names each failed or errored test as `classname::name`, so a retried network error or a failing test is visible without the raw output. The final `e2e-changed-tests` job succeeds only when no supported test files changed or the approved run completed all three passes. Fork PRs with selected tests fail this gate until a maintainer brings the reviewed change onto a same-repository branch
 
@@ -206,6 +206,8 @@ That snippet only conveys intent. What you actually write uses the real harness:
 
 Every HTTP call goes through the shared transport, never through `requests.*` in a test. `e2e_http.py` is the only module permitted to call `requests.*`, and that is enforced in CI by `tests/code_coverage_tests/check_e2e_no_raw_requests.py`. A test that imports requests will fail the check
 
+One deliberate exception: LLM-endpoint calls in `llm_translation/` go through the real provider SDKs (OpenAI, Anthropic) via the suite's `sdk` fixture (`llm_translation/sdk_clients.py`), because that is what customers actually run against the proxy (LIT-4577). Management routes and endpoints no official SDK covers stay on the shared transport, and raw HTTP client imports remain banned either way
+
 The shape is layered so tests stay declarative
 
 `transport.py` exposes a `Transport` Protocol with `post`, `get`, `delete`, `send`, `stream`, `probe`, plus `bearer(key)` and the `master` header. `HttpTransport` fulfils it, and `SplitTransport` routes each call by path to the data plane or the control plane so a split control-plane/data-plane deployment works without any change in the test

+"""Live e2e: the OTel v2 Langfuse generation carries output for every non-chat endpoint (LIT-8309).
+
+With LITELLM_OTEL_V2=true the proxy exports one generation per request to the
+team's Langfuse destination. Chat, Responses, embeddings and OCR already fill
+its output; this file pins the remaining five families. Each test registers a
+real OpenAI deployment, drives the endpoint through the shared transport, then
+reads the generation back from Langfuse and asserts its output reflects what
+the caller received: the completion text, the transcript, the moderation
+verdict, and for images and speech a bounded summary that never carries the
+raw base64 or audio bytes.

+"""Live e2e: a client hanging up mid-request under cancel_on_disconnect never
+benches the deployment it was talking to.
+
+The group is the cooldown suite's pair: the live Azure deployment holding all of
+the shuffle weight, benched on its first failure of any class with a cooldown that
+outlasts the test, plus a healthy backup at weight 0 the shuffle only reaches once
+the Azure deployment is benched. A cheap call first proves the Azure deployment
+answers the key and warms its auth path. The test then asks for an answer far
+longer than CLIENT_HANGS_UP_AFTER_SECONDS of generation, retries off, and hangs up
+that many seconds in: late enough that the proxy has handed the call to Azure (a
+hang-up before the provider call is in flight cancels nothing the router could
+bench, so the cell would pass vacuously). An answer that comes back inside the
+window proves nothing and benches nothing either, since a success never counts
+against the deployment, so the cell asks again up to HANG_UP_ATTEMPTS times and
+fails out loud naming the window only when every ask came back early. After the
+cooldown suite's replica propagation window, every one of the next calls has to
+come back 200 from the Azure deployment itself, named in x-litellm-model-id; a
+single answer from the backup means the hang-up was booked as a failure.
+
+The test reads `cancel_on_disconnect` back from the proxy first: without the flag
+the hang-up cancels nothing and the cell would pass vacuously.

-"""
-Regression test for https://github.com/BerriAI/litellm/issues/28505 -
-the Responses API bridge double-strips the provider prefix from the
-model name when a Chat Completions request has both `tools` and
-`reasoning_effort`.
-
-Root cause: the bridge handler called `litellm.responses()` /
-`litellm.aresponses()` without passing the already-resolved
-`custom_llm_provider`. The downstream call then re-invoked
-`get_llm_provider()` with `custom_llm_provider=None`, which stripped
-a second provider prefix from a `provider/provider/model` deployment
-string.
-
-This test pins both the sync and async bridge handler call sites:
-the resolved `custom_llm_provider` must be forwarded to the underlying
-`responses` / `aresponses` call so the provider isn't re-detected.

+Tests for BudgetReservationReleaseMiddleware.
+
+Auth reserves budget before the handler runs and hands the reservation to the
+request or socket state. A litellm call made through the async client wrapper
+claims it for the cost callback that runs after the call; anything still unclaimed
+when the response is done or the socket has closed would keep the spend counter
+pinned until its TTL, so the middleware releases it.
