* fix(responses): run stream failure and success hooks on the iterating loop instead of blocking it
A dropped provider stream on native /v1/responses ran the failure logging through run_async_function from inside the async iterator, which parks the event loop thread on a helper-thread future until every failure callback returns, and never returns when a callback waits on state only that loop can advance. With a running loop the failure handlers (and the completed-stream success deployment hook) are now scheduled as tasks on it, the way chat streaming already does; the sync iterator keeps its blocking path
* fix(responses): await stream failure and success logging on the iterating loop before propagating
Keep the merge-base hook set for the native Responses stream: async_failure_handler plus the executor-thread failure_handler on failure, and the post-call success deployment hook on completion. Inside a running loop the async handler is scheduled as a task on that loop and the async iterator awaits it before re-raising, so the loop is never blocked on a foreign-loop future and the failure is attributed before the router's fallback wrapper re-enters the same logging object. The sync iterator inside a running loop keeps the task fire-and-forget with a strong reference.
* fix(responses): submit the sync failure handler only after the async one finishes

* fix(proxy): read the compaction rate-limit gate's limiter from the proxy hook registry
* fix(proxy): count the pending request in read-only rate-limit checks and keep the compaction gate off the caller's parallel slot
The compaction polyfill's summary-model gate, once it ran against the real v3 limiter, showed two behaviors nobody had chosen. The read-only check compared the stored counter with the same `>` the increment path uses, but a read-only check decides a request that has not been counted yet, so a summary model exactly at its rpm limit still went out. The read-only path now adds the pending increment of 1 before comparing; the increment path is unchanged.
The gate also passed the key's max_parallel_requests gauge through, and the read-only gauge count includes the caller's own in-flight slot, so a key with max_parallel_requests: 1 never compacted. The gate now drops that gauge from its descriptors, since the summary call runs inside a request the limiter already admitted.

* fix(otel): detach post-response service spans by request phase, name redis spans by operation
Service spans logged from the post-response phase (success callbacks, the response-cache write) now root their own trace linked to the request span even while the server span is still recording, instead of only when they happen to end after it. Redis service spans are named `redis <operation>`; the litellm call chain that issued them moves to the `litellm.service.caller` attribute via a typed `ServiceLoggerPayload.caller` field.

* fix(otel): mark anthropic messages stream cache write as post-response phase
The /v1/messages streaming cache writer awaits async_add_cache inline
instead of going through create_cache_write_task, so its redis span
stayed parented under the request trace. Wrap the write in
post_response_phase so it detaches like the chat completions write.

* fix(ci): stop five stale or flaky CI reds and retry CyberArk policy-load conflicts
The Langfuse redaction unit test exports to a local OTLP capture instead of
polling Langfuse Cloud through a recorded lookup. The passthrough worker-kill
test only requires spend rows for requests the surviving worker served. The
spend-routes sweep treats the intentional /spend/capture_rate 503 as expected.
CyberArk retries a 409 policy load in Python, Rust and the e2e Conjur helper
instead of reading it as "variable exists". The integration egress guard now
matches the script's own cgroup, so it no longer blocks the CircleCI agent,
which runs as the same user.
* fix(ci): keep the policy-load backoff typed as float
* fix(ci): retry CyberArk policy loads without blocking the event loop and tighten the worker-kill and Langfuse tests
* fix(secrets): load CyberArk policy one request at a time per manager
* test(secrets): pin that non-conflict CyberArk policy failures are not retried
* test(unit): run tests/unit with only an allowlisted host environment
CircleCI's unit job inherits every project env var, so real provider keys,
REDIS_HOST, DATABASE_URL and AWS or Azure credentials reached tests that
assume none are set. Locally, litellm's import-time load_dotenv did the same
from any .env up the tree. The unit conftest now drops every variable outside
a small allowlist and disables dotenv before litellm is imported.
* test(e2e): name a failed search and the stuck batch status instead of misattributing them
The websearch session test read an empty web_search_tool_result_error block as a
successful search, so a failing search tool surfaced as a session billing bug.
The batch cancellation timeout now reports the last status the proxy returned.
* fix(ci): scrub the host environment per unit test instead of for the whole pytest process
GHA shards run tests/unit next to other suites in one process, so the import-time
scrub deleted MCP_TEST_PEER_PYTHON before tests/mcp_tests read it and the MCP
upstream fell back to the SDK2 interpreter. The two websearch tests that called
OpenAI and Perplexity live are removed: tests/unit no longer sees their keys.
* fix(ci): scrub only the host variables present before litellm is imported
The per-test scrub also deleted TIKTOKEN_CACHE_DIR, which litellm sets at import to
its bundled encodings, so tokenizer paths tried to download them and hit the
socket guard. The prisma setup test now passes its own database URL instead of
reading one another test leaked into the process environment.
* fix(ci): stop the order-dependent unit reds and settle logging tasks on their own queue
LoggingWorker marked a task done on whichever queue was current when the callback
finished, so a callback that outlived an event-loop change raised "task_done()
called too many times" or undercounted the new loop's queue. It now settles the
queue the task came from.
The rest are test isolation fixes for failures that only appeared when another
file ran first on the same xdist worker: a replaced user_api_key_cache, breaker
metrics unregistered by prometheus tests, semantic_router's health-check filter on
uvicorn.access, logging tasks carried over from bedrock tests, a Router-written
model_cost entry, and a stray post captured by the langflow test. The token
counter check now asserts bounded chunking instead of wall-clock time.
* test(e2e/ui): wait for the logout redirect before visiting a protected page
Logout revokes the session server-side before clearing cookies and navigating, so an immediate page.goto either ran with the cookie still set or was aborted by the logout redirect (net::ERR_ABORTED).
* test(unit): restore the prometheus metrics config per test and settle logs carried from earlier tests in the a2a cost tests
* test(router): pin the router clock in the usage counter tests so a minute rollover cannot empty the read
* test(e2e/ui): wait for logout to clear the token cookie instead of for a login redirect

* refactor(types): derive Anthropic beta string conversions with Strum
* fix(anthropic): report missing max_tokens as a missing field
* refactor(rust): type Anthropic messages headers and auth after the Python layout
Delete anthropic/messages/headers.rs. Its OAuth handling, credential ladder
and beta merging move to anthropic/common_utils.rs where Python keeps them
(optionally_handle_anthropic_oauth, get_auth_header, _merge_beta_headers),
and the feature beta injection becomes update_headers_with_anthropic_beta on
the messages config, as in Python. The BaseAnthropicMessagesConfig impl is
unchanged apart from the bodies of validate_environment and request_headers
Beta values are now the AnthropicBeta enum and BetaSet, which sort, dedupe
and comma-join by construction. Request params gain typed speed, tools and
context_management through Recognized, so the beta logic matches on enums
instead of string-comparing JSON. OauthToken parses the sk-ant-oat token once
and the chat config shares that detection instead of its own copy
Case-insensitive header helpers move next to has_header in litellm-http.
One deliberate divergence: a Bearer-prefixed OAuth key configured through
api_key or ANTHROPIC_API_KEY is sent with a single Bearer scheme, where
Python would emit "Bearer Bearer"

* fix(team): reject malformed team_member_max_budget_alert_emails on team writes
Thresholds outside 1-100, non-list recipients, and invalid emails now return 422 on
/team/new, /team/update and PATCH /team/{id} instead of being stored and silently
ignored. The value is stored canonically. Read-side LiteLLM_TeamTable is unchanged,
and the PATCH body stays a raw merge patch so a null threshold still deletes it.
* fix(auth): enforce and alert on team member budgets only in common_checks
The builder re-checked the team member budget inline before common_checks ran the same
check, so one request that crossed a team_member_max_budget_alert_emails threshold
dispatched two alerts. Drop the inline check; common_checks is the single authorization
point and already covers per-member rows, the team default member budget, zero-cost
skips and the cross-pod spend counter. Its 422 message now uses the TeamMember=user:team
form the builder and budget reservation already returned.
* Revert "fix(team): reject malformed team_member_max_budget_alert_emails on team writes"
This reverts commit 703e754b46.
* fix(alerting): keep BaseBudgetAlertType.get_event_message zero-arg
Requiring user_info broke existing callers and out-of-tree subclasses. The team member
label now comes from SlackAlerting.budget_alerts, so the interface and its Readme are
unchanged from main.
* fix(mcp): keep team member budget enforcement on the MCP OAuth auth dependency
The MCP OAuth dependency stops at _user_api_key_auth_builder and never reaches common_checks, so removing the builder's inline member budget check would have let over-budget members through there. Enforce it explicitly for that caller.
* fix(auth): keep main's team member budget enforcement, alert once per request
Restore the builder's team member budget check and 422 message exactly as on main and drop the MCP-only gate. The builder sends the member alert only on the request it rejects; common_checks sends it for requests that get past the builder, so no request alerts twice.

proxy_server.proxy_logging_obj with a MagicMock and never restored it.
Since the proxy unit tests joined tests/unit (#42903), 14 JWT mapping,
end-user and MCP tests on the same xdist worker awaited that mock and
failed. The test now uses monkeypatch.
test_prometheus_logging_callbacks set verbose_logger to DEBUG and
litellm.set_verbose at import, so every worker in the unit job ran with
DEBUG on. That broke caplog equality in the JEV classifier test, the
vertex streaming memory ratio, and four event-loop lag checks. The
module-level setup is removed; nothing in the file depended on it.
#43081 removed the OCR harness modules but left them in the
importability parametrize list.
test_get_model_info_bedrock_region reassigned litellm.model_cost and set
LITELLM_LOCAL_MODEL_COST_MAP without restoring either, and never cleared
the get_model_info caches, so it failed whenever an earlier test had
looked up the regional model. It now uses monkeypatch and invalidates
the caches; the local_testing isolation fixture also invalidates them
after restoring model_cost.
The Windows job hit CircleCI's 10 minute no-output limit while cargo

The legacy callback crate carried two rewrites that have nothing to do with the
Logging contract: litellm_credential_name inheritance and the max_budget and
num_retries_per_request checks. Any later callback host would need them
unchanged, which is the smell the crate's AGENTS.md now names. They are now a
Preflight the driver in litellm-host-python runs on the keyword view begin
returned, before the host projects from it, supplied by python-bridge and passed
through run_legacy_call. The call order is unchanged (setup, deployment hook,
credentials, limits) and a rejection still fails the call as a host failure, so
the failure callbacks run as before. The preflight rewrites the adapter's own
copy in place, so no extra dict copy and no new lifecycle method

* ci: rename fork-flag to unit-flag now that it applies on every event
* test: move tests/test_litellm root and small trees into tests/unit
Pure renames, no content changes. Follow-up commits in this PR fix
references, merge the three files that already existed in tests/unit,
keep live-provider tests in tests/test_litellm and wire CI.
* test: carry tests/test_litellm conftest isolation into tests/unit
Callback lists, routing fallbacks, cached HTTP clients, logger state, AWS,
proxy-URL and keychain env, and session-end client cleanup now reset for
unit tests too. The environment isolation owns its MonkeyPatch so a test's
own monkeypatch is undone before the model-cost teardown runs.
* test: merge, split and prune the moved root and small-tree tests
Merge batches/test_batch_utils.py and the chat_completions and messages
dispatch tests into the files that already existed in tests/unit. Keep
the live Gemini interactions tests, the async image-fetch format test and
the OpenAI embedding scorer test in tests/test_litellm since they need
real network or keys. Put test_router.py under tests/unit/test_router so
the existing package no longer shadows it. Delete eight tests the audit
found superseded by stronger ones kept in this move.
* ci: run the moved root and small-tree tests under their legacy flags
Add the misc and responses-caching-types flags to unit_selection.sh and
CircleCI, extend enterprise-routing and mcp-integration, and point the
legacy GHA shards, Makefile, redis-compat workflow, merge smoke manifest
and change classifier at the new paths.
* test: make the new tests/unit directories packages
tests/unit/test_package_layout.py requires every directory to carry an
__init__.py, and without one the moved and retained
test_litellm_responses_bridge.py modules collide on import.
* test: scope the unit socket block to tests/unit in shared sessions
The GHA shards collect the legacy test-path and the unit selection in one
pytest session. The unit conftest's loopback-only block leaked into legacy
modules that reach the network at import. The legacy conftest now lifts the
restriction at collect and setup time, and the unit conftest re-applies it
when collecting its own modules.
* test: move tests/test_litellm/llms into tests/unit/llms
Rename-only. Moves the provider tests and the fine-tuning fixtures they
load, mirroring the old paths. Follow-up commits merge, split and wire them.
* test: merge, split and prune the moved llms tests
Merges the Databricks chat transformation tests into the existing unit
file, keeps the tests that need real keys or the network in
tests/test_litellm, deletes the audited tests a stronger unit test
already covers, and points imports at tests.unit.llms.
* ci: run the moved llms tests under their legacy flags
The Vertex AI and All Other Providers shards keep their legacy test-path
for the retained files and add the llm-vertex-ai and llm-other-providers
unit selections. CircleCI gets matching unit jobs.
* test: make the tests/unit/llms directories packages
Adds __init__.py to the moved dirs and drops the legacy ones whose
directories no longer hold tests.
* test: drop script runners and path hacks the llms split left dangling
The __main__ runners in the split openai_like files and the Databricks e2e
runner called tests that now live in the other half of the split or were
deleted. The retained legacy halves also no longer need sys.path edits.
* test: give the shard-script tests their own GITHUB_OUTPUT
They only passed where the runner set it. The CircleCI unit job's env
allowlist drops it, so the script's redirect failed there.
* test: point the router and module-deletion checks at tests/unit
router_code_coverage and code_qa_check_tests only searched tests/test_litellm,
so the moved router tests no longer counted. The two silent-experiment tests
the audit deleted were the only direct callers of those methods; they are
replaced with tests that assert the forwarded shadow request and the
recursion guard.
* test: move tests/test_litellm integrations and secret_managers into tests/unit
Rename-only. Mirrors the old paths, including the directory conftests
and the prompt and JSON fixtures. Follow-up commits prune and wire them.
* test: prune and repoint the moved integrations tests
Deletes the 7 audited tests a stronger test in the same tree already
covers, imports the TLS sink helpers from their new conftest path, and
restores os.environ after each integrations test. Some presets write
OTEL_EXPORTER_OTLP_HEADERS straight into os.environ, and without the
legacy tree's test ordering that header leaked into the AgentOps tests.
* ci: run the moved integrations tests under their legacy flag
The integrations GHA shard and a new CircleCI job run the integrations
unit selection. secret_managers joins the misc selection.
* docs: point integrations and secret_managers references at tests/unit
* test: make the moved integrations directories packages
* test: keep the Databricks manual e2e runner and fix the SageMaker Nova run path
The Databricks e2e file is a manual script whose main() calls the tests
that were pruned, so pruning them broke the documented run. It is back to
its main version. The SageMaker Nova docstring now points at the file's
real location in tests/local_testing.
* test: move tests/test_litellm core utils, routing, responses, caching and rust_bridge into tests/unit
Rename-only. Mirrors the old paths, including fixtures, the stubtest config
and the native-route wheel script. Two files that collide with existing unit
files are merged in a follow-up commit.
* test: merge, prune and repoint the moved core, routing, responses, caching and rust_bridge tests
Merges the two files that collided with existing unit files, folding the
legacy extra case into test_is_chat_completion_cached_dict, and deletes the
9 audited tests a stronger test in the same file already covers.
Keeps what needs the network in tests/test_litellm: test_tokenizers pulls a
tokenizer from the Hugging Face hub, and the gpt2 and r50k_base tokenizer
cases download their BPE files. The unit core_utils conftest points
TIKTOKEN_CACHE_DIR at litellm's bundled encodings so the rest never depend on
import order to stay offline, and FakeSecretVault moves to a shared module
so both trees can build it.
* ci: run the moved core, routing, responses, caching and rust_bridge tests under their flags
core_utils gets a core-utils flag and CircleCI job, and its GHA shard keeps
the legacy path for the retained network tests. router_utils and
router_strategy join enterprise-routing, responses joins
responses-caching-types (minus responses/mcp, which mcp-integration owns),
caching joins caching-local and rust_bridge joins misc. The redis-compat,
test-rust, stubtest and merge-smoke paths follow the move.
* docs: point the Rust crate references at tests/unit
* test: make the moved core, routing and rust_bridge directories packages
* test: keep the no-loop DualCache batch_get_cache regression test
It runs the sync path outside any event loop, which the inside-loop test
cannot, so a change that picks the Redis client by loop state would only
show up there.

* fix(logging): redact raw_request when turn_off_message_logging is set in the proxy config
The raw request branch bound turn_off_message_logging by name at import, before the proxy config set it, so loggers kept receiving the prompt in metadata.raw_request and raw_request_typed_dict. It now runs the same per-request redaction check messages use, and json_logs is read at call time for the same reason

* fix(proxy): send a real error event when a /v1/messages stream fails
When a stream failed halfway through, the proxy wrote the error as a plain
`data: {"error": ...}` line with no `event:` in front of it. Anthropic clients
pick stream events by that name, so they skip the line and the request looks
like it simply stopped with nothing in it.
Write the failure as an `event: error` frame with Anthropic's own payload, and
take the error type from the status code
* fix(proxy): use the shared Anthropic error mapping for the stream error frame
The first pass added a third copy of the status to error-type table, and it
disagreed with the documented one: 529 came out as `api_error` rather than
`overloaded_error`, and 413 as `invalid_request_error` rather than
`request_too_large`, which hides the two failures a client can actually act on.
Drop that copy and put the frame builder next to the table litellm already
keeps in anthropic_interface/exceptions. The bridged adapter path was building
the same frame inline, so it uses the shared one now too
* fix(proxy): seal a torn SSE frame before the /v1/messages error event
An upstream that drops mid-frame leaves the client inside an open event,
so the error frame that follows is glued onto the torn data line and the
Anthropic SDK raises a JSON decode error instead of an APIStatusError.
Close the open frame with a ping event the SDK skips before writing the
error event, and add the e2e stream-cut edge with Bedrock, Anthropic
boundary, and Anthropic mid-frame legs.
* fix(proxy): keep the SSE tail unchanged on a chunk that is not text
A serializer that hands a dict or model object through as-is has no bytes
the frame tail can learn from, so advance_sse_tail leaves it alone instead
of slicing it.
* fix(proxy): answer a /v1/messages stream that fails before its first byte as a JSON error carrying its status
* test: move the Anthropic error frame tests into tests/unit
* test(e2e): cut the upstream stream only after content has been relayed
* test(e2e): carry split SSE lines across chunks and always tear a data line mid-frame

* fix(bedrock): surface a converse-stream 200 that decodes to no events as a 502 instead of an empty turn
* fix(bedrock): quote the body head only when a stream decoded no events
The leftover-bytes error keeps the byte and event counts, the content type and the request id but no longer quotes the first bytes of a stream that already decoded events, since that head is the start of a healthy stream and can hold model output. The anthropic_messages empty-stream warning no longer prints the request's model name.

* fix(responses): fall back on pre-output stream drops, fail truncated streams, honor request_timeout
A native /v1/responses stream that drops before any output item now raises
the router's fallback-eligible MidStreamFallbackError, so configured
fallbacks retry the original input. A stream that ends with a clean EOF or
a [DONE] marker but no response.completed, response.incomplete or
response.failed event now raises litellm.APIConnectionError instead of
ending as if it had completed: fallback-eligible before any output, an
explicit error after partial output. The sync iterator mirrors every branch.
resolve_llm_passthrough_timeout now consults an explicitly set
litellm_settings.request_timeout right after the router timeout and before
general_settings.pass_through_request_timeout, so the router's native
responses path honors it.
* test(responses): give the normal-completion stream tests a terminal event

Deletes the 7 audited tests a stronger test in the same tree already
covers, imports the TLS sink helpers from their new conftest path, and
restores os.environ after each integrations test. Some presets write
OTEL_EXPORTER_OTLP_HEADERS straight into os.environ, and without the

* feat(anthropic): placement policy for mid-conversation system messages
Pure functions over the OpenAI-format message list: split off the leading
system run, keep later system messages as role=system at a placement Anthropic
accepts on models flagged supports_mid_conversation_system (after a user turn,
before an assistant turn or the end, never adjacent), and convert them to user
turns in place elsewhere, keeping tool_result first in a merged user turn.
* fix(anthropic): keep mid-conversation system out of the chat completions system prompt
translate_system_message hoisted every role=system message, at any index, into
the top-level system block. On a conversation carrying a mid-session reminder
that rewrites the cached prefix, so the provider re-bills the whole history at
cache-write pricing on every turn (#36559). #36968 fixed this on /v1/messages;
the chat completions path, shared by first-party Anthropic, Vertex, Azure AI
and Bedrock Invoke, still hoisted.
Only the leading system run becomes the system prompt now. Later system
messages go through the placement policy, and anthropic_messages_pt emits a
system message instead of rejecting the role. The caller's message list is no
longer mutated. Tests pin the two-turn prefix invariant across all four chat
configs and both flag states.
* refactor(anthropic): single-source the converted system note
The /v1/messages pass-through and the chat completions path must prefix a
converted system turn with the same operator note.
* test(e2e): prove the prompt cache survives a mid-conversation system reminder on chat completions
Same priming and assertions as the /v1/messages cases, through
/v1/chat/completions with OpenAI-format messages, for first-party Anthropic
and Bedrock Invoke on a flagged (Opus 4.8) and an unflagged (Haiku 4.5) model.
The reminder sits between the assistant turn and the next user turn, the shape
OpenAI-style agent frameworks send, which is the placement the chat path has
to translate.
* test(anthropic): cover the cache_control rebuild shapes and type the test helpers
Codecov flagged the 5m ttl branch and the empty-system path of the wire
builder; both now have a test. Greptile asked for full typing on the new
test helpers.
* refactor(anthropic): read the mid-conversation flag through a public supports_ helper
supports_mid_conversation_system joins the other supports_* helpers in
litellm.utils, so the chat transformation stops importing the private
_supports_factory.
* chore(typing): declare the mid-conversation type aliases with TypeAlias
The Final sweep tightened LIT010, which exempts TypeAlias declarations but
counts a bare alias assignment as an unannotated binding.
* fix(anthropic): let add_code_execution_tool take the pass-through message union
The translator now emits role=system inside messages for models that accept it,
so anthropic_messages_pt returns the pass-through union. add_code_execution_tool
still declared the narrower user/assistant union while only ever reading
content, so upstream's strip_advisor_blocks_from_messages call in between made
the mismatch visible to the type checker.
* fix(bedrock): keep mid-conversation system messages in place on converse path
* fix: ruff format + multi tool_result order + regression test
* fix: satisfy type-discipline gate + update osv ignore for mlflow PYSEC-2026-3865
* fix(bedrock): restore role narrowing in hoisted system loop for basedpyright budget
* test(bedrock): cover mid-conversation system conversion branches
- non-dict guard in _opens_with_tool_result
- in-place conversion without tool context
- str/list cache_control preservation in mid-conversation path
- drop unreachable non-system guard in hoisted loop
* Place type-discipline suppressions on the lines the gate scans
* Narrow hoisted loop to system role so basedpyright sees the right TypedDict
* fix(anthropic): place mid-conversation system runs by their neighbours only
A run after an assistant turn now slides behind the user turn that
immediately follows it, and a run that ends the array or precedes an
assistant turn becomes a user turn in place. No later message can move
an earlier run, so a client that replays the conversation with more
turns appended sends a byte-identical prefix and preserved thinking
blocks keep their binding
* refactor(bedrock): share the converted system note with the anthropic module
Converse imports CONVERTED_SYSTEM_NOTE instead of carrying its own copy
of the same text, and the reordering helpers lose their comments
* test: pin the replayed request prefix across preserved-thinking turns
One test per audited feature, through the real entrypoint: the chat
transformations for anthropic, bedrock invoke, vertex and converse, the
modify_params dummy tool result, dotprompt with unchanged variables, and
Presidio masking against an in-process fake. Each serializes system,
tools and the earlier messages of turn N and N+1 and asserts they match.
The e2e mid-conversation system test imports its content blocks from
models.py again and is marked provider_live
* fix(anthropic): move mid-conversation system placement into prompt_templates
The prompt factory imported the placement helper from the Anthropic provider
package, whose common_utils reads a factory constant at import time, so loading
the factory first raised ImportError. The module now sits next to
anthropic_messages_pt and every consumer imports core utils
A user turn with content [] or None puts no block on the wire, so a system run
anchored to it landed first in messages or behind an assistant turn. Such a run
now converts in place; empty strings and empty text blocks still anchor because
the factory fills them with a placeholder
* fix(anthropic): anchor system messages only on user turns that reach the wire
* fix(bedrock): type the converse system-message helpers over the message TypedDicts
* fix(anthropic): read replayed pydantic messages in the Converse helpers and convert a system run whose assistant follower sends nothing
A history that replays the previous turn as the litellm.Message object
was invisible to the Converse system-message helpers, so a mid-conversation
system stayed between a tool call and its result or reached Converse as
role: system. The helpers now read fields through the shared
message_field and parts_of accessors and drop the local role predicate.
Flagged placement anchored a system run on any assistant follower, but
anthropic_messages_pt drops an assistant turn that puts no block on the
wire (content None, an empty list, an unsigned thinking part), so the
system landed directly before the next user turn, which Anthropic
rejects. Such a run now converts in place. An empty or whitespace text
turn still anchors, since the converter pads it with a placeholder.
* fix(anthropic): treat bridged encrypted reasoning as a vanishing assistant turn for system placement
An assistant turn whose only blocks carry Responses API encrypted reasoning is
dropped by anthropic_messages_pt, so a mid-conversation system run anchored
before it landed directly before the next user turn. The unsignable-thinking
predicate now lives in common_utils and both the factory and the placement
policy consult it.
* fix(anthropic): let an inline thinking part hide separate thinking_blocks in system placement
anthropic_messages_pt skips an assistant turn's separate thinking_blocks as soon
as its content list carries an inline thinking or redacted_thinking part, so a
turn whose inline part is unsigned puts nothing on the wire even when the
separate block is signed. The placement policy now mirrors that rule.

* refactor(types): declare litellm-owned params in one registry
* refactor(types): re-export registry constants without redundant aliases
* refactor(types): satisfy type-discipline rules in registry projections and tests
* refactor(types): classify every registry entry and check groups against typed config models
* test(types): pin load-bearing names and exact projections in registry tests
* style(types): keep agentic projection comment within ruff format
* refactor(types): declare litellm-owned params as typed objects and derive the lists from their fields
* refactor(types): fields of the typed objects become the registry; tests use a hand-written inventory
* refactor(types): split traversal into wire_names and owned_wire_names, move rust to kwarg artifacts
rust is a module-level switch (litellm.rust) that nothing reads from a call's kwargs, so it
joins self, use_client and model_config as a registered artifact instead of a DispatchOptions
field. The field constants now import from litellm.types.litellm_params directly instead of
through a re-export in litellm.types.utils. metadata and litellm_metadata are MutableMapping
because their readers mutate them in place, and client accepts raw httpx clients
* refactor(types): own max_agentic_loops as an option and walk only nested leaves
Move max_agentic_loops from AgenticLoopState to a new AgenticLoopOptions leaf under
LiteLLMOptions, since the interception handlers read it as a deployment ceiling rather
than stamping it. Drop the owned_wire_names fallback that treated an unresolved annotation
as a direct field, which under postponed annotations silently shrank the registry. Re-export
TRUSTED_CALLBACK_VARS_FIELD and ADDRESSED_RESPONSE_ID_FIELD from types.utils so that import
path keeps working. Tests use hand-written inventories for the callback and pricing names
* refactor(types): move data_residency to call state and drop aliased re-exports
data_residency is stamped by get_litellm_params and responses.main during the
call, so it lives on CallState, not CostOptions. mock_response also accepts a
float sequence, which main.py reads for mock embeddings. The types/utils.py
re-exports become one plain import with an exact F401 suppression instead of
two X as X aliases that pushed PLC0414 over its strict-gate ceiling. Redundant
leaf docstrings and the structural artifact test are gone; the re-exported
FIELD constants are checked by identity instead
* refactor(types): project owned kwarg names once and keep pass-through extraction in request order
* refactor(types): type caching_groups from its cache reader and hoist the pass-through ownership set
caching_groups is a sequence of flat model-group sequences, which is what
Cache._get_caching_group iterates. A regression test drives the public
cache key path so two groups in one caching group share a key and a third
does not. The pass-through endpoint builds its frozenset of owned names
once at import instead of per request, reads the two metadata carriers
from the extracted mapping instead of popping them, and its extraction
mappings are read-only. Concatenation tests assert the whole derived list
and tuple, docstrings drop reader claims that nothing in the module backs
* refactor(types): read owned names live in pass-through and pin tests to literal inventories
The pass-through endpoint checks body keys against the public all_litellm_params
list at request time again, as the base does, instead of a frozenset taken at
import, so a name registered after import is still extracted. A test drives
that path with a name added after import, and another sends both metadata
carriers interleaved with provider keys and asserts the whole merged result.
retry_policy accepts the mapping form its router reader builds a RetryPolicy
from. The pricing inventory in the typed tests is a literal tuple checked
against the model's fields, the agentic compatibility test asserts type, length
and set instead of declaration order, and the typed-model overlap tests assert
the exact intersection.
* refactor(types): move model_alias_map to CallState and read the owned registry in registry order in pass-through

* fix(vertex_ai): stop advertising OpenAI platform-only params on Gemma and Llama routes
The Anthropic /v1/messages bridge derives prompt_cache_key from Claude Code's
session id whenever the provider config advertises it, and every Vertex
OpenAI-compatible route (gemma/, openai/<endpoint>, meta/) inherited the full
OpenAI list, so the Model Garden vLLM container rejected each turn with a
pydantic extra_forbidden 400. Vertex's Llama and Gemma configs now filter one
shared list of platform-only params (prompt_cache_key, prompt_cache_retention,
safety_identifier, service_tier, store, web_search_options, modalities,
prediction, audio, max_retries) out of their supported params, so the bridge
no longer derives the key and drop_params drops an explicit one.

login's spend rows carried a different sha256 hash as api_key and the usage APIs
could resolve neither key_alias nor user_email for them. Spend rows and logging
callbacks now attribute a session request to its stable alias,
cli-session-<user_id>, and the usage endpoints derive that alias and owner from
the key itself instead of scanning for a matching digest
* fix(spend): resolve the CLI session team from the user's first team in usage metadata
A cli-session key carries no team of its own in the DB, so the usage
breakdown showed team_id None for it and the export grouped it as
Unassigned. The login attaches the user's first team to the session, so
the recovery mirrors that rule for cli-session keys only.
* fix(spend): claim the session team only for a single-team user
The CLI login attaches a team on its own only when the user has exactly
one; a user in several teams picks one per login, so usage metadata for
the alias would otherwise name a team the login may not have used.
* test(pass_through): mark the mocked auth object as a plain key
The logged key follows the alias only for a session token; a bare
MagicMock reads as one, so the test names the field it relies on.
* fix(spend): attribute CLI session pass-through, queue, and managed batch spend to the cli-session alias

* fix(spend): only treat the exact cli-session-<created_by> value as a batch key alias
A managed object row written by an older build can still carry the raw per-login
session token, which shares the cli-session- prefix. Matching on the prefix alone
would have surfaced that token as a trusted alias and persisted it verbatim in the
batch cost spend log, so the alias check now requires the exact per-user value and
every other prefixed value keeps going through redaction

* fix(spend): log proxy executed batch rows under the cli-session alias instead of the session token
_row_metadata set user_api_key from the raw bearer token while user_api_key_hash carried the alias, so the spend log redaction rejected the alias as untrusted and hashed the random session token instead

Replace passthrough_url/passthrough_transform with passthrough_response,

The binding drops the unused headers, status and api_base arguments.
Catch the ValueError/RuntimeError the binding raises so a relayed body
that is not OCR-shaped falls back to the passthrough object instead of
failing logging, and cover the relay against the real binding.

* fix(vertex_ai): translate /v1/responses batch rows through the Responses-to-Chat bridge
Vertex batch uploads treated every non-embeddings JSONL row as a chat
completions body, so a /v1/responses row lost its input and reached GCS
as a blank text part. Route detection now recognizes /v1/responses rows
and bridges them to chat through the same Responses-to-Chat bridge the
real-time path uses. That bridge call moves out of the Bedrock files
transformation into a shared helper both providers call, forwarding the
record's fields as sent, like real time, instead of validating them
against the SDK TypedDicts whose required keys clients omit.

* fix(logging): pass provider response headers to callbacks on every endpoint
Custom callbacks only received kwargs["response_headers"] for chat
completions. Responses, image generation and edit, speech, and
transcription calls either never recorded the provider's headers or
recorded them in one place and not the other.
Every handler now records the provider's httpx headers on the response's
hidden params as "headers" (raw) and "additional_headers" (processed,
with LiteLLM's own entries winning on a clash), and the logging object
derives model_call_details["response_headers"] from those hidden params
before cost calculation on the non-stream and both streaming success
paths, keeping a handler-set value authoritative. Binary speech responses
expose their hidden params to the standard logging payload, and the sync
OpenAI transcription request always fetches the raw response.
* test(images): point the legacy image and speech fakes at the raw response surface
Image generation now goes through the SDK's raw response so the provider headers can be read, and the speech binary response now carries hidden params. The unit fakes in the image generation, xinference, proxy provider, image edit, Vertex speech, and otel suites still pinned the old call surface and the old "no hidden params" assertion, so they read an uncalled mock or a fake response without headers.
* test(images): drop the rewritten mock comments and the generated edit PNGs
* test(images): move the llm-span test's image fake to the raw response surface

* feat(vertex): native batch JSONL passthrough with cost tracking
Add a per-request `passthrough=true` multipart field on `POST /v1/files`
(and the same kwarg on `litellm.create_file`) that uploads a native
Vertex AI batch JSONL to the deployment's GCS bucket unchanged, so rows
using `googleSearch` and other Gemini-only features run as written and
the output, `groundingMetadata` included, comes back untouched.
Passthrough is sticky through the GCS object path
(`litellm-vertex-files/passthrough/...`), so batch create and output
retrieval inherit it without new state. Native output rows are costed
from their `usageMetadata` with the deployment's model and model_info,
in the polling and retrieve paths and for the existing global
`disable_vertex_batch_output_transformation` flag, which billed $0
before.
The proxy requires the target to resolve to vertex_ai deployments only,
refuses `passthrough` with a non-batch purpose, a non-default
`target_storage`, or pre-call guardrails, and validates native rows on
`request` instead of the OpenAI batch keys.
* refactor(vertex): keep native batch row pricing inside the Vertex adapter
Moves native Vertex batch row detection, response parsing, and per-row
pricing from litellm/batches/batch_utils.py into
litellm/llms/vertex_ai/batches/transformation.py, so batch_utils only
aggregates the rows it gets back. Adds tests/test_litellm/files to the
misc unit shard so the new test directory is claimed by a shard.
* fix(files): say what a passthrough batch upload takes when a row is not native
The missing-key 400 listed bare key names, so an OpenAI-shaped row under
passthrough=true read "Each line must be a JSON object with keys request".
The batch line shape now carries its own hint, and the passthrough one says
a passthrough upload takes native Vertex batch rows with a request key
* fix(batches): bill native Vertex embedding batch rows on the native cost path
A native Vertex output row whose response holds an embedding was validated as a
generateContent response, so the documented tokenCount-only shape counted as a failed
row. Price embedding rows from their own usage (promptTokenCount, else tokenCount) with
the helper the transformed embeddings path already used, and drop the prompt-details
helper nothing calls anymore.
* fix(batches): keep modality batch rates on native Vertex embedding rows
An embedding row that carries usageMetadata was billed from promptTokenCount alone, so
its promptTokensDetails no longer reached the audio, image, and video batch rates the
way it did before the native cost path. Run every row with usageMetadata through the
Gemini usage parser and keep the flat tokenCount fallback for embedding rows without it.
* fix(batches): price native Vertex batch rows by modelVersion under a wildcard deployment
A `vertex_ai/*` deployment hands the batch cost path `*` as the deployment model, which
no cost map resolves, so every native (passthrough or flag-on) row was billed at $0. A
wildcard deployment model now defers to the row's own `modelVersion`, the way the
transformed path already prices by the row's `model`.
Also moves the native passthrough tests under tests/test_litellm, the tree codecov
reads, and covers the raw upload chunking, the embedding output translation, the
unpriceable-row path, and the flag-on dispatch.
* fix(batches): keep explicit deployment prices for native Vertex rows without a modelVersion
Under a wildcard deployment a native batch row that carries no modelVersion (an embedding
row, or a generateContent row Vertex returned without one) was billed at $0 even when the
deployment's model_info sets explicit batch prices, because the cost calculator was never
called. The row now falls back to the wildcard name, which the cost calculator prices from
the explicit model_info, and only a row with neither a modelVersion nor a deployment model
is billed at $0 with the warning

The new CircleCI tests pipeline (#42773) runs tests/unit under pytest-cov on
CPython 3.12.2, where coverage traces every line through sys.settrace. The two
tracemalloc peak comparisons in test_vertex_ai_files_streaming.py drive 8000-row
payloads through both pipelines and slow from ~10s to over 3 minutes under that
tracer, so both hit the 90s pytest-timeout on every run.
Mark them no_cover so pytest-cov pauses tracing for just these two. Their
assertions are unchanged and every other test in the file still reports coverage.

* test: point CircleCI-only suites at models still in the cost map
#42435 removed cost map entries past their deprecation date and #42437 added
litellm_uisettings to the config-synced tables, but both only updated
tests/test_litellm. The CircleCI-only suites (local_testing, llm_translation,
logging_callback_tests, litellm_utils_tests, unit) kept using the removed
models or the old table list and went red on main.
Each test keeps its assertions and swaps the removed model for a current one
with the same provider and capabilities. The fireworks tests pick a vision
model from the cost map because #34941 set supports_vision false on
minimax-m3, and the vertex image provider test injects the image model set
because #42435 removed every vertex_ai-image-models entry.
