Subject: [PATCH 005/317] fix(proxy): renew budget reservation counter TTL
 while the request is in flight

A reservation lives inside spend counter keys that expire on the Redis idle
TTL (60s). A stream that outlives the TTL dropped its reservation, so a
concurrent request on any worker was admitted against the DB floor until the
stream reconciled. Renew the counter TTL with EXPIRE every ttl/2 while the
reservation is open and stop once it is finalized, so an idle counter still
expires on its own if the worker dies.

Subject: [PATCH 007/317] fix(proxy): stop reservation lease renewal once the
 request task is gone

A streaming /v1/messages client disconnect skips reconciliation, so the
lease kept the orphaned reservation alive until request_timeout instead of
the plain 60s counter TTL the base branch had. Stop renewing when the
request task that took the reservation is done.

Subject: [PATCH 008/317] feat(ui): add upgrade banner with latest release
 changelog stats

Adds GET /get/latest_release_info, which fetches the latest stable GitHub
release once per hour per worker and buckets its PR bullets by conventional
commit prefix into new features, fixes, and other updates. The Admin UI
compares the running proxy version to that release and shows a dismissible
top banner with the stat line when the proxy is behind. Dismissal is stored
per release version in localStorage so the banner returns for the next one.

Subject: [PATCH 009/317] fix(ui): fix CI failures on upgrade banner PR

Use Annotated[..., Depends(...)] instead of a call in the default value
to clear the B008 ruff budget. Extract an inline test object over the
no-large-inline-object-arg eslint budget. Mock UpgradeBanner in the
layout test, matching the other top banners, since it now renders through
react-query hooks that need a QueryClientProvider the test doesn't set up.

Subject: [PATCH 016/317] fix(auth): screen bulk-update passwords concurrently
 before any db write

/user/bulk_update awaited a separate HIBP lookup for each user in the
batch, so a degraded-slow HIBP (5s timeout per lookup) could stretch a
500-user batch to ~2500s and time out the request after some updates
had already persisted.

validate_passwords_bulk dedupes the batch's passwords, strength-checks
first, then fires every needed HIBP lookup concurrently, bounding the
worst case at one 5s timeout window. bulk_update_processed_users now
screens the whole batch before the serial update loop, so a rejected
password fails only its own entry and validation failures precede any
persistence.

Subject: [PATCH 018/317] fix(auth): annotate the strict-rule suppressions the
 merged gates now count

The staging merge brought BLE001 into the strict ruff set and lowered the
LIT002 ceiling, so the HIBP fail-open except and the params/headers dicts
in password_policy.py now need their noqa and mutable-ok reasons. The
headers dict moves to an annotated Final so the suppression fits the line
limit.

Subject: [PATCH 019/317] feat(auth): add self-service change-password endpoint

Admin password sets on /user/update and per-user /user/bulk_update stay
supported and policy-enforced. The request model hides the password from
repr so management alerts never format the plaintext, and the all_users
bulk path rejects passwords instead of writing one plaintext value to
every row.

Subject: [PATCH 020/317] fix(auth): clear the CI gates on the change-password
 PR

The Terraform endpoint audit wanted POST /user/password/change covered
or allowlisted; it is a caller-scoped one-shot action, so allowlist it
next to /user/bulk_update. leftnav.test.tsx mocked next/navigation
without useRouter, which SidebarAccountMenu now calls, so every render
in that file threw. The two unannotated audit-log patches in
test_password_endpoints.py get their test-quality-ok reasons.

Also removes the LIT002 violations the PR added: prisma input TypedDicts
annotate the where/data dicts, a shared HTTPExceptionErrorDetail
TypedDict covers the HTTPException detail dicts, and the route decorator
takes a tags tuple.

Subject: [PATCH 022/317] feat(auth): screen the login password inline and
 restrict the session on a fresh breach hit

A breach found during a login previously only flagged the account for the
NEXT login, handing out one free unrestricted 24h session. The HIBP screen
is now awaited before the session key is minted (worst case one 5s window
per user per 24h, fail-open unchanged), so a fresh hit restricts the
current session and the dashboard routes straight to change-password.

Also repairs two casualties of merge f5e47974db that the layout tests
caught: the lost usePathname import and a call to migratedHref, which
staging renamed to uiHref.

Subject: [PATCH 023/317] refactor(auth): type the breach-screen DB dicts and
 flatten the session-key kwargs

Annotate screen_login_password_for_breach's update/where dicts with
prisma input TypedDicts and replace authenticate_user's conditional
dict splat with plain keyword arguments, clearing the LIT002 lines
this branch added in login_utils.py. No behavior change: an unflagged
login now passes allowed_routes=None and metadata={} explicitly, which
are the parameter defaults

Subject: [PATCH 027/317] perf(proxy): serialize /model/info listing once with
 orjson

FastAPI walked the multi-megabyte /model/info payload through jsonable_encoder
before json.dumps on every request. Return a prebuilt orjson Response instead,
keeping jsonable_encoder as the fallback for datetimes and other non-native values

Resolves LIT-5724

 success handler twice

_client_async_logging_helper re-submitted logging_obj.success_handler to the
executor after _dispatch_success_logging had already done so, running the same
success pipeline twice per async request and racing on shared logging state.

Subject: [PATCH 031/317] feat(edenai): add Eden AI as a provider

Routes edenai/<provider>/<model> deployments to Eden AI's OpenAI-compatible API at https://api.edenai.run/v3
with EDENAI_API_KEY and EDENAI_API_BASE, and bills the per-request cost Eden reports instead of a price-map
estimate, streams included

Chat completions and the edenai/* wildcard (Eden's live catalog) go through the OpenAI-compatible base.
/v1/responses and /v1/messages reach Eden's native endpoints so stateful Responses and untranslated Anthropic
payloads work. Embeddings, transcription, speech, image generation and video generation get per-surface
configs that lift Eden's cost from the body or the x-edenai-cost header. A completed Responses stream event
that reports usage.cost is now billed that number for every provider, matching chat streams

Admin UI provider entry, README row, endpoint matrix and provider docs tests updated; tests live under
tests/test_litellm/llms/edenai

Subject: [PATCH 041/317] fix(proxy): count unprefixed release bullets and
 coalesce concurrent latest release fetches

Unprefixed release bullets now count as other_updates, concurrent cache misses share one upstream GitHub request through an injected asyncio.Lock, and the dashboard upgrade banner is announced as status rather than alert

Subject: [PATCH 042/317] feat(team): show whether a member follows the team
 default budget and allow resetting to it

Adds budget_source (team_default, custom, none) to each membership in /team/info and a
POST /team/{team_id}/member/{user_id}/reset_budget route that relinks a member to the team's
shared team_member_budget row without touching their spend. The Admin UI team members table
shows a Team default or Custom badge next to each member's budget and offers a
Use team default action on customized members

Subject: [PATCH 047/317] fix: apply configured cache_control_injection_points
 beside client cache_control marks

Configured injection points were dropped whenever the request already
carried a client-set cache_control anywhere, so an operator's rolling
tail checkpoint silently never landed once a caller marked its own
system prompt. Only the automatic defaults stand down now. Configured
points skip a target the client already marked and stay under the
provider's 4-block cap, counting the client's marks on messages, system,
tools and the root cache_control first. The chat path carries the tool
count as a stamp on the points because the prompt-management hook never
receives tools.

Fixes #40675

+Unit tests for the bedrock_mantle native Anthropic Messages route.
+
+Mantle serves its Claude models only on `/anthropic/v1/messages` (the OpenAI
+paths reject them), so `bedrock_mantle/anthropic.claude-*` requests on
+/v1/messages must hit that endpoint directly instead of the chat-completions
+bridge. These tests lock the dispatcher gate, the URL derivation from the
+OpenAI-surface base that get_llm_provider pre-fills, the version header, the
+Bearer/SigV4 auth chain, and the wire request through the public entrypoint.

Subject: [PATCH 094/317] fix(azure_ai): bridge Foundry function-tool requests
 only where the chat surface rejects them

Foundry's OpenAI v1 chat surface rejects function tools with an explicit
reasoning_effort from gpt-5.6 on and with reasoning left on from gpt-6 on,
while gpt-5.4, gpt-5.5 and unset-effort gpt-5.6 serve them. Key the
azure_ai bridge on those measured boundaries instead of the azure
provider's gpt-5.4+ rule so working chat traffic keeps its n, logprobs,
seed and chatcmpl ids.

Subject: [PATCH 097/317] fix(token_counter): count replayed redacted_thinking
 blocks so prompt_caching keeps pinning

A conversation that replays a redacted_thinking block (Anthropic redacted reasoning, or the
/v1/messages bridge's stand-in for a reasoning item that carries no summary) made
_count_content_list raise, is_prompt_caching_valid_prompt swallowed that to False, and the
prompt_caching pre-call check neither recorded nor pinned the serving deployment, so the
conversation bounced across the group and paid a cache write on every deployment. The block
now counts like a thinking block with no text: zero tokens for the encrypted payload.

Subject: [PATCH 099/317] fix(anthropic_messages): only Mantle consumes
 get_llm_provider's api_base

The /v1/messages handler passed the api_base get_llm_provider resolved to every
provider's native messages config, which shadowed DEEPSEEK_ANTHROPIC_API_BASE and
TENCENT_ANTHROPIC_API_BASE with the chat default and changed the azure_ai
precedence. Messages configs now opt in through uses_get_llm_provider_api_base(),
true only for Bedrock Mantle, whose region-prefixed model must resolve to a
region host before the prefix is stripped. Also registers
BedrockMantleAnthropicMessagesConfig in the lazy import registry.

Subject: [PATCH 101/317] fix(litellm): keep a function tool without a body on
 the chat route

A tools entry of only {"type": "function"} has nothing for the Responses
bridge to convert, and the bridge raised a 500 for it where the chat
route returns the provider's own 400. The gate now counts a tool as a
function tool only when it carries a function body or a top-level name,
on every provider the gate serves

 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:
+
+```python
+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

Subject: [PATCH 105/317] fix(router): keep prompt caching affinity when the
 breakpoint moves

The prompt_caching pre-call check keyed a deployment pin on a hash of the
whole cacheable prefix, cache_control markers included. Agent clients
such as Claude Code move the marker to the newest user turn on every
request, so the key changed every turn, the pin never matched, and a
multi-turn session drifted across deployments and lost its provider
cache.

Hash the prefix per content block with the markers stripped, chained so
every block position has a key, and write the pin at the breakpoint
block. Lookup walks back over the last PROMPT_CACHE_LOOKBACK_POSITIONS
positions (a run of tool_use or tool_result blocks counting as one), the
same window the provider probes for a cached prefix, in one batch cache
read. Both sides hash the prefix after base64 truncation so a request
carrying raw image bytes derives the keys the success event stored.

Subject: [PATCH 109/317] fix(router): hash the prompt caching affinity prefix
 off the event loop

Offload the per-block hashing through offload_token_count on both the pre-call
read and the success-event write, hash raw bytes as base64 instead of raising,
drop the unused serialize_object helper, and bind the chained digest, the
message envelope, and the bytes path in the regression tests

Subject: [PATCH 115/317] ci(e2e): fix the stage-mirror batch reds and keep a
 redacted pytest log

The changed-test gate booted its stage-mirror stack without files_settings
or finetune_settings, so every raw upload with a custom_llm_provider hit a
500, and it exported the whole provider env into the gateways, so the
AWS_ROLE_NAME the assume-role test needs made the GovCloud deployment run
an AssumeRole with its static keys. The gate also deleted its pytest output,
so a red run left nothing to read. The mirror config now carries the
openai, azure, and vertex_ai file settings, gateways start without
AWS_ROLE_NAME, and the workflow uploads the pass logs and junit files with
every secret value, every field of a JSON-valued secret, and their
XML-escaped forms replaced before the raw files are removed.

Subject: [PATCH 121/317] feat(proxy): default to the v2 migration resolver

The migrations Job entrypoint (migrations/run.py) has defaulted to v2 with
USE_V2_MIGRATION_RESOLVER=false as the opt-out, and the Helm chart documents
that knob. Proxy startup still defaulted to v1, so the two paths disagreed
about which resolver a deployment runs.

Proxy startup now resolves the same way: v2 unless USE_V2_MIGRATION_RESOLVER
is false or --use_legacy_migration_resolver is passed.

- --use_v2_migration_resolver stays accepted as a no-op that warns, so
  existing commands and Helm values do not fail on an unknown option.
- The dedicated Postgres smoke-test job is repointed at the legacy resolver
  so v1 keeps real-DB proxy-boot coverage, and the two jobs that deselected
  it by name are updated to match the rename.

#39178 reverted an earlier flip because two replicas sharing a database
deadlocked (40P01 / P3018) with neither answering /health/liveliness. That
contention is what #40932 coordinates, which is why this builds on it.

Subject: [PATCH 122/317] ci: keep real-database coverage for both migration
 resolvers

The Postgres-backed smoke job previously exercised one resolver. Running
the default and the legacy variants in it covers v2 now that it is the
default, without losing v1's coverage.

Subject: [PATCH 123/317] test(llms): migrate phase 6 provider unit tests to
 tests/unit

Migrate 18 provider test files from tests/test_litellm/llms to tests/unit/llms.
194 kept tests move as-is after mutation testing; 1 test deleted
(test_completion_datarobot_with_environment_variables, env-gated no-assert);
the fixture-only fal_ai cost calculator file is removed.

Subject: [PATCH 131/317] test(llms): migrate phase 7 provider unit tests to
 tests/unit

Move the wave 1 phase 7 batch (fireworks_ai, gemini, gigachat, github_copilot; 20 files) from tests/test_litellm to tests/unit after judging every test function under a behaviour mutation. Seven wiring or mock-echo tests that stayed green are deleted. The fireworks cost calculator tests get a local model_cost save/restore fixture since the tests/unit tree has no shared conftest for it

 New rules and lowered/equal limits are fine. So is a rule that graduated: once a
 paired config (ruff.toml for the ruff-strict budget) selects the rule outright it
 hard-fails at the first violation, which is stricter than any ceiling the budget
 could hold, so dropping its entry tightens the guard rather than removing it.
+Likewise a retired rule: once the paired checker (check_test_quality.py for the

+loosen.
 
 This is deliberately NOT a gating check. It should turn the run red so that a
 loosening is impossible to miss in review, but it must stay OUT of the

Subject: [PATCH 139/317] fix(proxy): only warn about the deprecated flag when
 it came from the CLI

USE_V2_MIGRATION_RESOLVER=true is a supported way to select v2, but click
sets the same parameter from that env var, so the deprecation notice fired
for environment-based config that is not deprecated. The notice now keys off
click's parameter source.

Also drops an em dash from the notice, and moves the resolver decision under
mock-free tests by making it take the env value as an argument.

Subject: [PATCH 142/317] feat(policy_engine): add default fallback policy
 attachments

A policy attachment with default: true applies only when no non-default
attachment matches the request, so an opt-in guardrail policy replaces the
fallback one instead of running alongside it. Supported in config.yaml,
/policies/attachments, the Admin UI Attachments tab and the resolver
(matched_via is prefixed with default:).

Subject: [PATCH 143/317] test(google): boot the unified Google proxy fixture
 with a real master key

#42019 made the proxy refuse to start on a publicly known master key, and the
session fixture in tests/unified_google_tests started its in-process proxy with
sk-1234, so six tests errored in setup before reaching a provider

Give the fixture, the config it loads, and the SDK client the same non-default
key instead of the override the other harnesses took, so the boot check stays
live in this suite

-"""
-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.

+Dispatch-contract tests for litellm/videos/main.py
+
+Each public video operation is a pair: a sync `video_*` worker (decorated with
+@client) that resolves the provider, fetches the provider config, logs, and then
+forwards to exactly one `base_llm_http_handler.video_*_handler`; and an async
+`avideo_*` wrapper that delegates to the sync worker in an executor.
+
+This file locks the contract of that layer so a regression fails loudly:
+
+  1. DISPATCH   - the one correct handler fired and every sibling video handler
+                  asserted NOT called. A copy-paste that calls the wrong handler
+                  (e.g. remix -> edit) flips this.
+  2. RESULT     - the handler's return value is propagated by identity.
+  3. PROVIDER   - custom_llm_provider is decoded from an encoded video id when not
+                  passed (status/content/remix/edit/extension), or defaults to
+                  "openai" (list/create_character/get_character). This is the exact
+                  surface of the historical "content defaulted to openai" bug.
+  4. PAYLOAD    - the provider config object and the operation's identifying args
+                  (video_id/prompt/name/...) reach the handler; _is_async is False
+                  on the sync path.
+  5. SHORT-CIRCUIT - mock_response returns a typed object without any handler call.
+  6. UNSUPPORTED   - a None provider config raises before any handler fires.
+  7. DELEGATION    - avideo_* returns the sync worker's result untouched, sets
+                     async_call=True, and pre-resolves the provider where it must.
+
+Seams mocked: the http handler (network), the provider-config registry lookup,
+get_llm_provider, and the video-generation optional-param builders. The id decode
+helper runs for real against genuinely-encoded ids, so the provider assertions
+reflect production.

-@client) that resolves the provider, fetches the provider config, logs, and then
-forwards to exactly one `base_llm_http_handler.video_*_handler`; and an async
-`avideo_*` wrapper that delegates to the sync worker in an executor.
-
-This file locks the contract of that layer so a regression fails loudly:
-
-  1. DISPATCH   - the one correct handler fired and every sibling video handler
-                  asserted NOT called. A copy-paste that calls the wrong handler
-                  (e.g. remix -> edit) flips this.
-  2. RESULT     - the handler's return value is propagated by identity.
-  3. PROVIDER   - custom_llm_provider is decoded from an encoded video id when not
-                  passed (status/content/remix/edit/extension), or defaults to
-                  "openai" (list/create_character/get_character). This is the exact
-                  surface of the historical "content defaulted to openai" bug.
-  4. PAYLOAD    - the provider config object and the operation's identifying args
-                  (video_id/prompt/name/...) reach the handler; _is_async is False
-                  on the sync path.
-  5. SHORT-CIRCUIT - mock_response returns a typed object without any handler call.
-  6. UNSUPPORTED   - a None provider config raises before any handler fires.
-  7. DELEGATION    - avideo_* returns the sync worker's result untouched, sets
-                     async_call=True, and pre-resolves the provider where it must.
-
-Seams mocked: the http handler (network), the provider-config registry lookup,
-get_llm_provider, and the video-generation optional-param builders. The id decode
-helper runs for real against genuinely-encoded ids, so the provider assertions
-reflect production.

Subject: [PATCH 187/317] fix(anthropic): forward safeguards and anthropic-beta
 unchanged on native /v1/messages

Native Anthropic Messages requests derived their allowlist from
AnthropicMessagesRequestOptionalParams, which lacked safeguards, and the
shared beta-header filter dropped betas unknown to the provider mapping
even when the upstream is api.anthropic.com itself. Claude Code auto mode
then saw no safeguard_results and fell back to billed classifier calls

+# Token counting
+
+`Tokenizer` is the text-counting interface. `TokenCounter` applies LiteLLM request, message, and tool accounting using any implementation of that interface
+
+The `fast` feature provides `fast::FastTokenizer` from `litellm-token-counter-fast`. `TokenCounter::from_json_fast`, `TokenCounter::from_cl100k_ranks`, and `TokenCounter::from_o200k_ranks` use 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`
+
+The Hugging Face and tiktoken backends are enabled by default. The hand-written fast backend is opt-in. With `default-features = false`, callers can supply their own `Tokenizer` to `TokenCounter::new` without compiling a built-in 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

+The Hugging Face and tiktoken backends are enabled by default. The hand-written fast backend is opt-in. The Python extension builds with `fast` only, which keeps the wheel at the size it had before the split. With `default-features = false`, callers can supply their own `Tokenizer` to `TokenCounter::new` without compiling a built-in 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

+All three backends are enabled by default. The Python extension builds with `fast` only, which keeps the wheel at the size it had before the split. With `default-features = false`, callers can supply their own `Tokenizer` to `TokenCounter::new` without compiling a built-in backend

+# 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

+# 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, and the Python-compatible response codec. 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. 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. Each Redis constructor currently opens its own connection; shared connection pools remain follow-up work
+
+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 exposes `NativeCacheHandle`, `CacheResolver`, and captured `CacheBinding` objects for host integration. Memory and Redis handles support synchronous and asynchronous response lookup and storage
+
+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
+
+Explicit facade registration checks object identity, method overrides, and configuration changes before selecting native execution. Registration does not migrate entries or replace Python methods. Until activation configures one shared service, a registered facade and its native handle 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
+
+## 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 batches, response reconstruction, callback scheduling, and failure-policy integration. This foundation does not switch those request paths
+
+Redis cluster, disk, cloud stores, dual caching, and semantic caching remain follow-ups. Atomic counters, affinity claims, reservations, queues, and pubsub need explicit capabilities owned by their consuming features. Adding a cache backend does not establish those guarantees

Subject: [PATCH 223/317] test(e2e): gate the Bedrock edge capture behind a
 provider_edge_host opt-in

The Buildkite ephemeral stack runs the gateway in another pod, so it cannot reach the pytest host's provider edge. The GitHub changed-e2e lane runs gateways on the runner and sets E2E_PROVIDER_EDGE_HOST_REACHABLE

 Point the proxy at bogus provider credentials for the replay run and it still has to pass: that is the whole proof that nothing left the process. Bundles are never committed. `tests/e2e/.fixtures` is gitignored because a bundle holds verbatim provider response bodies and hard-fails after seven days. CI records and replays this lane on a schedule in `.github/workflows/e2e_record_replay.yml`, publishing the bundle as a private `e2e-fixtures-bundle` artifact instead of committing it, selecting the tests with the `@pytest.mark.replayable` marker, and proving the bogus-credentials replay hermetic by counting provider egress with `.github/scripts/e2e_egress_sentinel.py`
 
-Current limits: Bedrock cannot be mounted (SigV4 signs the Host header, so a rewritten api_base fails signature verification), deployments baked into the proxy's config file cannot be edge-wired (only `/model/new` registrations can carry the edge api_base), and a file upload routed by `custom_llm_provider` through the proxy's `files_settings` block never passes a deployment at all, so the batches `model_param` and `provider_fallback` scenarios keep uploading live in every mode
+Current limits: Bedrock cannot be mounted in record or replay (SigV4 signs the Host header, so a rewritten api_base fails signature verification); a test that needs to observe the Converse body registers its own `LiveEdge` with `provider_edge_bedrock.bedrock_signer` re-signing the forwarded request, and carries the `provider_edge_host` opt-in marker because the gateway must reach the pytest host, which the Buildkite ephemeral stack cannot (the GitHub changed-e2e lane, whose gateways run on the runner, sets `E2E_PROVIDER_EDGE_HOST_REACHABLE`). Deployments baked into the proxy's config file cannot be edge-wired (only `/model/new` registrations can carry the edge api_base), and a file upload routed by `custom_llm_provider` through the proxy's `files_settings` block never passes a deployment at all, so the batches `model_param` and `provider_fallback` scenarios keep uploading live in every mode

Subject: [PATCH 230/317] fix(model_prices): add groq qwen3.6-27b deprecation
 date and bedrock qwen3-next regional pricing

Groq lists qwen/qwen3.6-27b for shutdown on 2026-09-14. Adds the six regional
Bedrock qwen.qwen3-next-80b-a3b entries priced per AWS's published regional
rates (absorbs #42191) with a regression test that the regional entry is used
instead of the US rate

Subject: [PATCH 237/317] fix(anthropic): type safeguards and safeguard_results
 as the arrays Anthropic sends

Driving a real Claude Code 2.1.278 through the proxy, and a direct call to
api.anthropic.com, both show these two fields are JSON arrays on the wire rather
than objects. The request carries safeguards as
[{"type": "dangerous_tool_use", "classifier_context": {...}}] under beta
dangerous-tool-use-2026-09-03, and the 200 comes back with safeguard_results as
[{"type": "dangerous_tool_use", "status": {"type": "available", "tool_uses": {...}}}].

No runtime change: the request filter matches on TypedDict keys and never inspects
the value. The test fixtures move to the captured shapes so the regression tests
pin what the client and the provider actually exchange.

+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 move that blocking work off the executor
 
 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

+The extension exposes `NativeCacheHandle`, `CacheResolver`, and captured `CacheBinding` objects for host integration. Memory and Redis handles support single and batch response lookup and storage. Batch lookup returns ordered values plus missing indices for embedding partial-hit wiring
 
 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
 
-Explicit facade registration checks object identity, method overrides, and configuration changes before selecting native execution. Registration does not migrate entries or replace Python methods. Until activation configures one shared service, a registered facade and its native handle can hold separate data. Existing public cache constructors remain on Python
+Explicit facade registration checks object identity, method overrides, effective TTL, and configuration changes before selecting native execution. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. Registration does not migrate entries or replace Python methods. Until activation configures one shared service, a registered facade and its native handle 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

+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, cloud stores, dual caching, and semantic caching remain follow-ups. Atomic counters, affinity claims, reservations, queues, and pubsub need explicit capabilities owned by their consuming features. Adding a cache backend does not establish those guarantees

+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 exposes `NativeCacheHandle`, `CacheResolver`, and captured `CacheBinding` objects for host integration. Memory and Redis handles support single and batch response lookup and storage. Batch lookup returns ordered values plus missing indices for embedding partial-hit wiring
+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
+
+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
 
-Explicit facade registration checks object identity, method overrides, effective TTL, and configuration changes before selecting native execution. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. Registration does not migrate entries or replace Python methods. Until activation configures one shared service, a registered facade and its native handle can hold separate data. Existing public cache constructors remain on Python
+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 configuration changes before selecting native execution. It does not compare Redis connection settings. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. 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

+Redis cluster, disk, cloud stores, and semantic caching remain follow-ups. 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.

 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

It does not compare Redis connection settings. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. 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.

+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. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. Public activation must construct the shared native service from the initial Python Redis settings. 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

Subject: [PATCH 252/317] fix(bedrock): send s3BucketOwner on batch input and
 output data config

Resolve s3_bucket_owner from litellm_params, then optional_params, then
AWS_S3_BUCKET_OWNER and emit it on both S3 data configs so cross-account
batch buckets pass Bedrock ownership validation. Omitted when unset

 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. Redis defaults come from the Python settings snapshot, including `litellm.default_redis_ttl`, and buffered async writes honor `redis_flush_size`. Public activation must construct the shared native service from the initial Python Redis settings. 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

Subject: [PATCH 275/317] fix(bedrock_mantle): bill Mantle's un-versioned
 Claude ids from a Mantle cost row

Mantle serves anthropic.claude-haiku-4-5 without the dated -20251001-v1:0
suffix the Bedrock row carries, so the native route billed it at 0. Add a
bedrock_mantle/anthropic.claude-haiku-4-5 row and let a
bedrock_mantle/<region>/<model> name fall back to the region-free
bedrock_mantle/<model> row before the provider-prefixed lookup. Also
satisfy the mutable-collection gate in the native messages transformation.

Subject: [PATCH 276/317] chore: keep main's lazy OpenAPI snapshot

The snapshot check runs on Python 3.12, which keeps the indentation of a route docstring that Python 3.13+ strips at compile time, so regenerating it locally on 3.14 produces a file CI rejects.

Subject: [PATCH 286/317] fix(anthropic): forward Claude Code safeguards and
 dangerous-tool-use beta to Bedrock Invoke and Vertex on /v1/messages

Claude Code's server-side auto-mode classifier sends a `safeguards` body field
together with the `dangerous-tool-use-2026-09-03` beta. PR #42152 made the
first-party anthropic route pass them through, but the beta header mapping
left the other two Claude platforms at null, so Bedrock Invoke dropped both
(classifier silently disabled) and Vertex forwarded the body field without
the beta, which the platform rejects with "safeguards: Extra inputs are not
permitted" (a 400 Claude Code hides by retrying without them).

Map the beta for bedrock and vertex_ai in the beta headers config and add
`safeguards` to the Bedrock Invoke request allowlist so the pair reaches
both platforms unchanged. Nothing is injected: a client that sends
`safeguards` without the beta still gets the platform's 400, exactly as
api.anthropic.com answers it.

Subject: [PATCH 304/317] fix(ci): let the install smoke test boot its key-less
 proxy config

The install smoke test starts the proxy on test_config_no_auth.yaml, which has no master key on purpose, and #42019's boot check now refuses that, so the three installing_litellm_on_python jobs have been red on main since 2026-09-20. Pass the documented local-dev override to the proxy child so the test keeps its no-auth config and the boot check stays as it is
