* refactor(rust): drop the tool discriminator without mutation and use rstest in DeepSeek tests
* feat(rust): add the Vertex AI Anthropic Messages config
* fix(rust): normalize Vertex system turns the way Python does
Vertex uses the shared normalize_system_role_messages: a leading run is
hoisted, a later turn stays or is converted in place by the model's
supports_mid_conversation_system, and billing blocks are filtered after the
hoist so one inside a system-role message no longer reaches Vertex.
* fix(rust_bridge): keep non-Claude Vertex Messages calls on Python
The catalog admits every vertex_ai Messages call, but Rust serves only Claude
there and reports anything else as a terminal InvalidProvider instead of a
decline. The dispatcher now bypasses Rust for those models, as
get_provider_anthropic_messages_config does.
* refactor(rust): template the Vertex location and project errors
The location failure is the shared InvalidType detail and the missing project
is MissingSetting with the provider, setting, param and variable name, so no
sentence is spelled at the return site.
* test(rust): use rstest in the Vertex AI Messages tests
* refactor(rust): derive the missing Vertex project error from its spec
* refactor(rust): give Messages configs typed litellm params
* feat(rust): port _normalize_system_role_messages for Messages hosts
mid_conversation_system mirrors Python's module function for function: a
leading run of system turns is hoisted into the top-level system, a later
turn stays in place when the model map flags supports_mid_conversation_system
and otherwise becomes a user turn where it was, never between a tool_use and
its tool_result, and billing blocks are stripped from the hoisted system. The
capability joins MessagesModelCapabilities and the bridge projection. Azure AI
uses it in place of fold_system_role_messages, which hoisted every turn.
* fix(rust): keep the Bedrock runtime endpoint behind a blank api_base
* refactor(rust): import LitellmParams from its crate instead of a re-export
* refactor(rust): template the Messages request decode errors
Both decode failures go through ErrorDetail::invalid with the subject and the
serde error as source instead of a preformatted sentence.
* refactor(rust_bridge): read the module globals the param specs name
The Messages host no longer keeps its own list of litellm globals; a spec
whose spellings the call leaves out names the global to read, so the next
family that has one needs no host change.
* refactor(rust): give each route lookup Python's implicit None
ProviderConfigManager's per-route methods list only the providers the route
serves and fall through to None; the Rust lookups now do the same, so a new
LlmProviders variant touches only the route that serves it.
* refactor(python-bridge): ship a signature base and read the resolved call
NativeCall carries base (positionals by name plus signature defaults) instead
of the fully bound dict. resolved lays kwargs over base, which is what bound
held, so every pre-hook read and every route host keeps seeing the same values.

* fix(lens): price agent traces by joining gen_ai.response.id to spend logs
Trace spend now joins each model call to spend_logs on one key: the
span's response id (gen_ai.response.id or the id the normalizers read
from OpenInference/LangChain output) against spend_logs.response_id or
the upstream id embedded in a managed resp_ id. The litellm.call_id and
traceparent transport join paths and the per-row ownership gate are
removed; the spend SQL still restricts rows to what the reader can see.
A run with some unpriced calls now reports the sum of its priced calls
plus priced_calls, instead of an unknown total.
* test(lens): cover response id spend join and partial trace totals
* chore(lens): regenerate trace types for priced_calls
* feat(lens): show partial run cost as a lower bound with priced call count
* fix(lens): treat litellm.call_id as the same assigned call id for spend joins
The id LiteLLM assigned to a call is either the response id it returned
(gen_ai.response.id -> spend_logs.response_id) or its gateway call id
(litellm.call_id -> spend_logs.litellm_call_id). Both are exact ids the
gateway mints and logs, so the join stays one rule. Transport span
matching and the ownership gate stay removed.
* test(lens): cover litellm.call_id spend joins and restore captured totals
* feat(lens): link each priced model call to its spend log
Spans gain spend_log_request_id, the spend_logs.request_id the call was
priced from, and spend_match, which says whether a model call matched or
why not (no assigned id on the span, no spend log with that id, or an
ambiguous match). A model call span is priced from the same ids as the
run total, so its cost and the total agree.
* test(lens): cover spend log links on model call spans
* chore(lens): regenerate trace types for spend log links
* feat(lens): open the matched spend log from an LLM step
An LLM step's header now shows a Spend log chip with the matched
request id and cost; clicking it opens the request log drawer over the
run, fetched by the exact spend_logs.request_id instead of the span's
own response id. Unpriced steps say why (no assigned id on the span, or
no spend log with it). Tree rows show each model call's cost, and a
partial run cost shows its priced call count inline.
* test(lens): cover the spend log link and unmatched cost reasons
* feat(lens): show the spend log link as a bordered LiteLLM Spend Log button
* feat(lens): add a back link from the spend log drawer to the agent trace
* feat(lens): label the spend log back link Back to Lens trace with the Lens icon
* fix(lens): ignore assigned ids that name no spend log when pricing a call
An id that names no row no longer vetoes the call, so a span carrying
both a response id and a call id still prices from a spend row logged
before litellm_call_id existed. An id naming two or more rows makes the
call ambiguous, and the match reason comes from the same per-id result,
so a single matched row with no cost is reported as matched.
* fix(lens): price a trace only from spend logs in its own team
A reader with several teams could see the same assigned id in another
team's spend log; only rows from the trace's team now price it. The
user and key ownership gate stays removed.
* perf(lens): resolve each model call's spend once per trace
Model call matches are computed once when the trace is resolved and
looked up by span index, instead of scanning the model call list for
every span and walking the graph again for spans, agents and the run
total.
* fix(lens): hide a step's Cost fact only when its spend log link shows the cost
* chore(lens): drop narrative doc comments from the spend join
* fix(lens): price a model call only when its ids agree on one spend log per span
* fix(lens): keep pricing spend logs written before litellm_call_id by their request id
* fix(lens): price every attempt a model call's ids name when they agree
* refactor(rust_bridge): remove rule-gated native secret-manager selection
Mirror the cache treatment: SecretManagerRule/SecretManagerContext and the resolve_native_* binding plumbing are gone. The Rust bridge now selects the native backend from the explicitly configured client (capture_secret_manager / _SecretManagerRuntime.from_client), and get_secret_from_manager is the plain Python handler path.

if-chain in mod.rs that reached into each module differently.
The modules now share one way to read attributes: present() for the first
non-empty key and Payload for a text that also reports the key it consumed,
replacing three different idioms and the &mut Vec threaded through payload
readers. Instrumentation::adjust returns a new Extraction instead of mutating
one, with each SDK rule as its own function, and the LangChain middleware
suffix list exists once.

Replace the AnyOf grant tree with a flat OwnedLogs(user_id, team_ids) scope,

the tree back into that shape.
A caller with no user id now gets an empty scope instead of matching ownerless
rows through Prisma's IS NULL. The dead request_id guard in ui_view_spend_logs
is removed, and the management facets inject the log team lookup and reuse
read_scope_sql instead of the list shim.

* 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"

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

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
* 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.
* test: keep the job's UNIT_FLAG out of the shard-script tests
* fix(url_utils): block 192.0.0.0/24 on every Python patch release
* test: move the new budget limiter tests into tests/unit/router_strategy
* test: move the new sentry scrubbing tests into tests/unit/litellm_core_utils
* test: move the new zerobus tests into tests/unit/integrations
* test: make tests/unit/integrations/zerobus a package
* test: load litellm's own tiktoken cache setup once instead of resetting it per test
