The shared disconnect release dispatched to the legacy limiter, which decrements unconditionally, so a rejected realtime attempt freed a slot it never took. The generic release is v3-only again and the Responses WebSocket close releases through its own method

* test(e2e): perf datastore limits count what a request waits on, background Postgres and Redis work reported on its own
postgres_calls_per_request and redis_calls_per_request were whole-server totals (pg_stat_database commits, Redis INFO
commands), so spend flushes and config reloads moved them and a new per-request lookup could hide in the noise. They
now count the statements and commands a request waits on before it is forwarded (auth and routing reads, the
rate-limiter script), from pg_stat_statements read before and after the run and a Redis MONITOR connection held
during it. Spend writes, daily aggregates, config reloads and cache invalidations are postgres_background_calls_per_request
and redis_background_calls_per_request. The run output lists the top statements and commands per bucket, and the
counters are read right after the run so the test's own spend sample is not counted

* fix(terraform): send additional_drop_params to the proxy instead of deleting the keys it names
litellm_model treated additional_drop_params in additional_litellm_params as a
provider-side delete list: it never sent the list and removed every key it named
from litellm_params, so vertex_location vanished and requests still carried
store. The list now goes to the proxy like any other JSON value, so the proxy
drops those params per request. Approach credited to #38345.
Fixes#38349
* fix(terraform)!: validate additional_drop_params and read it back from the proxy on refresh
* docs(terraform): note that a non-list additional_drop_params now fails the apply
* fix(terraform)!: check additional_drop_params at plan time and refresh listed keys and outside lists
* fix(terraform)!: show every listed key an older provider deleted in the upgrade plan and leave outside drop lists alone
Refresh no longer reads listed keys back from the proxy, which left a
plan diff that never cleared when a listed key was removed from config.
When the proxy has no stored list, the plan now shows the list and each
listed key the config sets as changes. A drop list set outside Terraform
on a model whose config has none stays out of the plan, and an empty
value now fails the plan
* fix(terraform): show a listed merge_reasoning_content_in_choices in the upgrade plan
The refresh now clears merge_reasoning_content_in_choices when it is listed and the proxy has no stored list, since an older provider deleted it, and no longer clears litellm_credential_name, which the older provider always sent
* test(e2e): attach perf case metrics and limits as JUnit properties
The perf case only printed its metrics table, so a green run left no numbers
behind. Each observed metric and its limit now land as <property> entries on
the test's JUnit testcase, named perf_<metric>[_p<percentile>] and
perf_<metric>[_p<percentile>]_limit, so project-releaser can collect them
* test(e2e): compare perf properties exactly instead of through pytest.approx
basedpyright flags pytest.approx as partially unknown in the e2e lint step,
so the harness test now uses metric values that are exact in binary floating
point
* fix(responses): write one spend-log row per native WebSocket turn
Each response.create turn on a native Responses WebSocket connection logs and bills as its own call when its terminal event arrives, keyed by the resp_ id the client saw, instead of one row at socket close that sums every turn
* test(responses): mock the websocket slot release and mark the per-turn start time naive
* style(responses): keep the per-turn start time line within ruff format
* refactor(responses): type websocket turn events as read-only mappings
* fix(responses): settle the websocket budget reservation on the first turn only
Every per-turn logging copy carried the connection's admission reservation, so two turns whose cost callbacks overlapped could both reconcile it. The first turn keeps the reservation and later turns charge their cost directly
* fix(proxy): keep the legacy limiter's websocket slot until disconnect
A websocket turn callback no longer decrements current_requests in the legacy limiter. The socket's slot is released once from arelease_max_parallel_requests_on_disconnect, which now dispatches to the legacy handler as well

* fix(sso): share SAML sign-in state over Redis without enable_redis_auth_cache
SAML login tickets, the single-use assertion mark and cached IdP metadata
lived in user_api_key_cache, which only gets Redis when
enable_redis_auth_cache is on. With several replicas or workers the IdP
callback often landed on a process that never saw the ticket and got a
401, and IdP-initiated sign-in was refused even with Redis configured.
SAML state now has its own DualCache that _attach_redis_usage_cache
always wires to Redis, like the CLI SSO session cache, and the SAML cache
calls are async.

* fix(guardrails): honor streaming settings on the Noma v2 guardrail
The Noma v2 initializer now passes streaming_buffer_until_moderated,
streaming_end_of_stream_only, streaming_sampling_rate and
streaming_buffer_release_on_scan from the guardrail config to
NomaV2Guardrail, so the unified streaming hook applies them. The
constructor validates them, so a custom guardrail class built on
NomaV2Guardrail gets the same checks. Unset keys keep the hook defaults,
and an invalid value is ignored with a warning naming the guardrail, so
the guardrail still loads.
Resolves LIT-9633
* test(guardrails): cover Noma v2 streaming settings across clients, failures and workers
Adds integration cells for the custom-subclass loader, string and invalid
values, unset and false keys, a Noma outage with and without block_failures,
an upstream rejection, n=2 choices, pre_call and non-streaming guardrails,
the OpenAI and Anthropic SDKs (sync and async), stored-guardrail info, a
PATCH while traffic flows, a burst while Noma is down, a slow Noma, and
replaced workers.
Resolves LIT-9633
* test(guardrails): pin the PATCH probes to one worker at a time
Each probe suspends the other worker and opens a fresh connection, so the
test checks that every worker applies the patched setting.
Resolves LIT-9633
* test(guardrails): check sampled scans by count, not window position
/v1/messages hands the streaming hook raw network reads, so where the
default sampling windows fall depends on timing; the base leg caught one
shifted window. Check the scan count and the final full-text scan instead.
Resolves LIT-9633

K2 in test_logging_only_scope_chaos.py flaked on CircleCI with
AttributeError: type object 'BaseModel' has no attribute '__pydantic_core_schema__'
raised inside the OpenAI client while its 30-thread control burst parsed responses
The SDKs define their response models with deferred schemas, so the first parse of each
model rebuilds it, and pydantic's model_rebuild is not safe when several threads hit it
at once. Every integration worker now builds those schemas in pytest_configure, before
any test can start a thread pool

* test(responses): verify websocket authorization

* test(responses): type the authorization capture
Replace the mutable header list with a typed, final Future carrying the upstream authorization value, addressing the review on #40853
* Refactor test_openai_websocket_authorization method
* fix(responses): resolve websocket keys with the deployment's provider
Pass the deployment custom_llm_provider to get_llm_provider so an api_base
host never swaps in another provider's env key, and drop the OpenAI-only
global key fallbacks so non-OpenAI websocket deployments resolve their own
env keys the way the HTTP route does
* fix(responses): let a deployment's own websocket key beat env keys
A deployment with an api_base on a host litellm recognizes, and no declared
provider, got that host's env key ahead of its own api_key. The explicit key
now always wins, matching the HTTP Responses route. Drop the litellm_params
api_key fallback, which could never be set because api_key is a named argument
* fix(responses): keep openai deployments on other providers' known hosts on the HTTP stream
An openai deployment whose api_base is a known OpenAI-compatible provider
host (DeepSeek, Groq, ...) opened a native Responses WebSocket there and got
a 405, because those hosts serve /responses over HTTP only. Route it through
the managed HTTP stream with the deployment's own key instead.
* fix(responses): resolve openai deployments on known provider hosts as that provider
An openai deployment whose api_base is a known provider host (DeepSeek,
Mistral, ...) now resolves to that host's provider on the Responses
WebSocket again, as before this branch, so it keeps that provider's
chat completions bridge, pricing and env key fallback. Its own api_key
still wins over the env key. The known-host test now mocks the upstream
HTTP route and checks the route, the bearer and response.completed.
* test(responses): prove websocket deployment keys and declared providers reach the provider socket
* test(responses): use the reported bare model shape for the websocket deployment key cell

* refactor(rust-bridge): let each route host pick the body params
The native routes projected request body params from a name list, hard-coded in
Rust for Messages and read from `PARAMETERS` for Chat Completions and Responses.
Each route host now answers `body_params(request)` over the keywords the call would
send, so the Python side owns which params reach the provider. No behavior change

* test(ui): close each federation spec API connection so the proxy cannot drop an idle keep-alive socket
* test(ui): send Connection: close on every integration browser spec API call
* test(ui): send Connection: close on every integration browser request from the Playwright config
* fix(router): carry a 429 status on cooldown and no-deployment errors
RouterRateLimitError and RouterRateLimitErrorBasic had no status_code, so the
proxy answered an all-deployments-cooled-down request as a generic 500 class
error and logged the bug report notice for every cooldown. Both now carry
status_code 429, which the proxy maps to a rate_limit_error and which the
retry policy already treats as retryable
* fix(proxy): start Sentry at config load and never attach request bodies
Sentry only came up inside set_callbacks on the first LLM call, so boot and
background errors were never reported, and general_settings.alerting: [sentry]
always raised Missing SENTRY_DSN because the alerting path read a dead
litellm.utils pin instead of the live SDK. The proxy now initializes Sentry
once while loading the config whenever sentry is a configured callback or
alerting target, the alerting and failure handlers read the live instance, and
max_request_body_size is pinned to never so prompts and completions stay out
of Sentry events
* fix(tracing): log Lens failures at ERROR and export row counters to Prometheus
A tracing store that fails to start, or a Lens service that rejects a batch,
was only logged at WARNING, so operators running at the default ERROR level
never saw tracing silently go dark. Both now log at ERROR and name the lens
store. The exporter's rows_written and rows_dropped tallies were never
exported, so the two counts are now Prometheus counters
litellm_lens_export_rows_written_total and
litellm_lens_export_rows_dropped_total, registered lazily on the default
registry like the other proxy-level counters and charted on the all-metrics
Grafana dashboard
* test(proxy): drop the litellm import the alerting tests no longer use
* fix(proxy): start Sentry once a DSN is set, from any config source
Boot-time init used to lock Sentry in even with no SENTRY_DSN, so a DSN loaded later from DB environment_variables was never picked up. initialize_sentry now skips when no DSN is set and re-inits when the DSN changes. alerting_handler calls it too, so alerting: [sentry] set through the DB works. Drops the litellm_settings.callbacks check since that config fails to load with sentry in it
* fix(sentry): keep stack frame locals out of events unless PII is opted in
Frame locals carried prompts (messages, request bodies, provider options) into every error event. include_local_variables now follows SENTRY_SEND_DEFAULT_PII
* test(router): drop the test that only pinned the 429 class attribute
* fix(proxy): start Sentry at boot when it is only an input callback
* fix(proxy): keep Sentry init and alerting within the strict ruff and basedpyright ceilings

The proxy answers POST /v1/mcp/server with 201 and DELETE /v1/mcp/server/{id} with 202, but handleMCPAPIResponse, handleAPIResponse, Client.sendRequest and resourceLiteLLMMCPServerDelete treated every status other than 200 as a failure. terraform apply created the server on the proxy, then reported an error and never wrote the resource to state, so the next apply created a duplicate, and destroy failed on the 202.
Accept any 2xx in the four status checks, treat an empty or null 2xx body in handleAPIResponse as an empty ModelResponse, and cover each path with httptest tables that fail on the 200-only comparison.
Re-lands the diff from #40723 on current main.

* test(integration): hand every harness server a port from one per-worker block
About 45 places in the integration harness picked a port by binding port 0,
reading the number back, closing the socket and starting a server on that
number later. Another process could take the port in between, which surfaced
as "Address already in use" flakes. Earlier fixes retried around the race in
single call sites without removing it.
tests/integration/_support/ports.py now owns every port the harness picks
ahead of a server. Each pytest process claims a 200-port block between 10000
and 32767 by taking an exclusive flock on a per-block lock file in the system
temp directory, so parallel runs on one machine never share a block and the
lock goes away with the process. The range is above the fixed service ports
and below the Linux and macOS ephemeral ranges. Ports go out in order, are
never reused in a run, skip anything an outside process already holds, and
a process that exhausts its block claims the next free one.
The three _free_port copies, worker_endpoints' port-0 binds,
free_loopback_port, the owned proxy's lost-port-race retry and the owned
Redis retry loop are gone. Tests that restart a server on the same port now
allocate that port up front instead of reading it back from the first
server. TQ012 in scripts/check_test_quality.py rejects a port-0 bind read
back with getsockname anywhere under tests/integration.
* ci(integration): record listening sockets and the ephemeral port range
* Revert "ci(integration): record listening sockets and the ephemeral port range"
This reverts commit d3fafc3da2.
The route host now reports get_configured_request_timeout() in MessagesSettings, and prepare uses the call timeout first, then that setting, then the 600s default. Before this, litellm_settings.request_timeout and REQUEST_TIMEOUT were ignored on the native path, so a long turn that works on Python timed out after 10 minutes

* fix(anthropic): drop unknown legacy thinking keys under drop_params when rebuilding adaptive thinking
* fix(bedrock): drop unknown thinking keys under drop_params on display updates rebuilds

* fix(gemini): continue long decode on CONTINUATION and cancel interactions at /cancel
* feat(gemini): add public gemini-4-argon cost-map rows for AI Studio and Vertex AI
Add gemini/gemini-4-argon and vertex_ai/gemini-4-argon alongside the existing
early-access row, carrying the same limits and capabilities. The AI Studio row
mirrors the early-access entry; the Vertex row differs only in provider and
pricing source. Prices follow once Google publishes them.
Extend the mapped metadata test to cover all three ids, that each routes to its
provider, that its backup copy matches, and that the public rows carry the same
limits as the early-access row.
* feat(gemini): raise gemini-4-argon to the 1M long decode cap and report initial_prompt_tokens across hops
* chore(prices): build on the merged gemini-4-argon rows and only raise the long decode cap
* fix(gemini): follow continuation hops in a loop instead of recursion
The unary hop collectors and the stream iterator called themselves once per continuation request, which the recursion check in CI rejects and which would hit the interpreter's call depth on a very long output. They now loop, and a test follows more hops than the interpreter allows nested calls
* fix(gemini): bill Google Search grounding from every continuation request
Google sends search grounding once, on the request that ran the search, and does not repeat it on a continuation request. The merged response kept only the last request's grounding, so usage.web_search_requests and the per-search fee dropped every earlier search. Unary merges and the stream iterator now carry the grounding of every request in the chain
* fix(gemini): continue long gemini-4-argon answers on streams and Vertex AI
A continued stream stopped after the first chunk of its second request. The stream wrapper asks the iterator for a fresh start before every chunk, and that reset it to the first request's finished stream. The iterator now reads from the newest request's stream
On Vertex AI the continuation request went to the v1 API version, which rejects continuationToken with a 400. A request that carries the token now goes to v1beta1, which accepts it, including a token that v1 issued
On a stream, initial_prompt_tokens came from a usage chunk in the middle of the stream, which reports a smaller prompt count than the last chunk. It is now the count the first request's stream ends with, the same number a unary call reports
continuation_token is no longer forwarded on the Interactions API, which answers 400 for the field. It is dropped there as it was before this branch
* chore(gemini): name the type errors the dual-mode stream iterator trips
The stream iterator holds a sync or an async line iterator in one untyped attribute. Pointing it at a continuation request's stream gave the type checker a concrete union for it, so six existing lines that only ever run in one of the two modes started to report errors
This adds a rule-named suppression with a reason on each of those lines and changes no code. Splitting the class into a sync and an async iterator would remove them and is left for a follow-up
* fix(gemini): continue only when Google ends a request with CONTINUATION, and stop streaming mid-answer tokens
A long decode now sends the next request only when Google's finish reason is CONTINUATION, so an answer cut at the caller's own max_tokens returns in one request with its continuation_token instead of drawing a rejected extra request
A request for more than one choice is never continued, since Google rejects a continuation with more than one candidate
Chat-format streams no longer carry the tokens Google sends mid-answer. Only a stream that ends cut off carries a continuation_token, on its last content chunk
The response cache key now includes continuation_token, so a resend with a token is not served the earlier segment
* fix(gemini): keep one response id across a continued answer
A continued chat stream changed its chunk id each time the next request to Google started, and a unary answer came back under the last request's id. Every chunk and the unary answer now carry the first request's id, including the chunk that ends a cut-off stream
A request whose n or max_tokens arrives as a string is sent once and never continued, where it used to fail with a 500 on the comparison. An empty continuation_token no longer changes the cache key
* test(gemini): add integration cells for long decode continuation
Covers continued answers on chat, /v1/messages and /v1/responses, streamed and not, on the Gemini API and Vertex AI against a scripted Google, plus concurrency, outage and worker restart runs
Also moves the Google stand-in cancel route to /cancel, the URL this PR now calls for Interactions cancel, and checks the cancel test posts there exactly once
* fix(vertex_ai): fetch the access token again before each continuation request
A long Gemini 4 answer on Vertex AI can run for over half an hour of follow-up requests, and every one of them reused the bearer token fetched before the first request. Once that token expired Google answered 401 and the caller got a cut-off answer with finish_reason length
Each Google request in a chain now asks for the token again, which is a cache hit until the token nears expiry, on the streamed and unary paths, sync and async. A refresh that fails counts as a failed follow-up, so the caller still gets the answer so far with its continuation token. A caller's own Authorization in extra_headers still wins on every request, and the Gemini API key path is unchanged
* fix(vertex_ai): start each continuation stream with an empty parser buffer
When a Google stream ended on an unfinished frame, its leftover text stayed in the stream parser and every frame of the next continuation stream was appended to it. None of them could be decoded, so the whole continuation was billed and dropped without an error
Each continuation stream now starts with a fresh buffer, and a test covers a stream that ends on an unfinished frame, sync and async
* fix(vertex_ai): treat a continuation stream with no readable frame as a failed follow-up
A continuation stream that answered 200 and then sent Google's error frame first, sent a body that is not JSON, or dropped before its first frame ended the caller's stream with `stop` or an error and no token, so a cut answer looked complete or was lost. It now ends the way a refused follow-up does, with the answer so far, `finish_reason` length and that request's token
Every continuation stream request now also gets the caller's per-request timeout, which #46349 added to the first one, so a follow-up that never answers ends at that timeout the same way
* fix(vertex_ai): keep every follow-up's citations and URL context in a continued answer
A non-streamed answer that took several Google requests kept citationMetadata and urlContextMetadata from the last request only, and left every later request's offsets counting from that request's own text. So a URL read on the first request was missing from the answer, citations from earlier requests were dropped, and a later request's citations and search supports pointed at the wrong part of the joined answer
The joined answer now keeps every request's citations (Vertex AI's `citations` and AI Studio's `citationSources`) and URL context, and shifts each later request's citation and search support offsets by the UTF-8 bytes of the answer text sent before it, thought parts excluded, since Google counts these offsets in bytes
* fix(vertex_ai): answer when a candidate sends null citationMetadata or urlContextMetadata
A Gemini candidate whose citationMetadata or urlContextMetadata was JSON null made the call fail on every Gemini model, non-streamed with a 422 or 500 and streamed with an error event, because the per-request metadata helper handed the null back as is and the caller tried to extend a list with it. A continued answer also failed when a follow-up's citation or search support came with a null startIndex
A null field is now kept as one entry on a single request, as it was before this branch, a follow-up's null URL context adds nothing to a continued answer, and a null startIndex counts from the start of that request's text. Tests cover missing, null and empty fields on one request and on a continued answer, streamed and not
* fix(vertex_ai): pass through spans with no end index and point a continued stream's citations into the whole answer
A later request's citation or search support with no endIndex made the whole non-streamed answer fail with a 500, so a span Google sends without an end index now comes back as Google sent it, the way one request for the whole answer returns it. A span with an end index but no start index still counts from 0
A continued stream handed callers each later request's citation and search support offsets counted from that request's own text. The stream now adds the answer bytes of every earlier request, so the offsets point into the whole answer like the non-streamed path and one request for the whole answer
Adds the audit's wire tests for both, which fail 24 cells before this change
* test(vertex_ai): cover a later request whose cited span starts at its first byte with no start index
Google leaves out a zero startIndex, so the second request of a continued answer can cite its own opening with only an endIndex. These wire cells check that span lands where one request for the whole answer puts it, on Gemini and Vertex AI, chat and Responses, unary and streamed
* fix(vertex_ai): log a continued answer's raw response as one object
A non-streamed answer joined from several Google requests logged its raw response as a JSON list of every request's body. The OpenTelemetry logger reads that raw response as one Gemini body to set its `llm.gemini.*` attributes, so on a continued answer it hit a validation error and set none of them
It now logs the merged body, which carries only the last request's token, and a single request still logs Google's body unchanged. The new unit test fails with the change reverted
Also adds integration cells for a cut chat stream's token chunk, an answer joined from 41 requests, a caller that gave up on a non-streamed call, counts and caps that are not numbers or are sent twice, `n` sent as true, a partial answer cached after a refused continuation, the token in another provider's cache key, and the sync SDK path with its Vertex token refetch
* test(integration): check a continued answer logs one merged raw response
A non-streamed Gemini answer that took several Google requests now hands logging one merged response, so the OpenTelemetry span carries the llm.gemini attributes. These 12 cells fail on the merge base and on the commit before that fix, and pass on the branch
* test(vertex_ai): cover a follow-up tool call and its thought signature in long decode
* test(gemini): pin that a one-request answer logs Google's body unchanged
* test(integration): assert the streamed usage.cost matches the spend row on every cost case
* test(integration): type the streamed usage frames as JsonValue
* test(integration): only require streamed usage.cost when the client received a usage frame
