fix(proxy)!: answer 400 for malformed tools on count_tokens instead of crashing (#46583)
* fix(proxy): answer 400 for malformed tools on count_tokens instead of crashing

A non-list tools value crashed the vector store lookup during auth and the
built-in tool cost lookup in the failure logging path, so the proxy answered
an unhandled 500 and closed the keep-alive connection. count_tokens now
answers a 400 invalid_request_error for a malformed body, drops malformed
tools when drop_params is on, and both lookups skip values of the wrong shape.

* fix(proxy): skip non-list tools in the tool allowlist check

Also validate the count_tokens body without recursion, which the recursion detector rejects.

* test(integration): restore the int tools case on count_tokens

The proxy now answers a non-list tools value with a 400, so the case is deterministic again.

* fix(proxy): reject malformed tools at the LLM route entry and keep vector store checks on malformed ids

* fix(proxy): apply drop_params like core when dropping malformed tools, and reject malformed tool vector store ids

Check tools after request setup so the Claude Code default and the logged call type apply, read the request,
global, and model group drop_params the way core does, drop tool_choice and friends with tools, cover Gemini
generateContent, and answer 400 for a malformed tools[].vector_store_ids with the strict flag off

* fix(proxy): keep the request's call type when logging a gate rejection after request setup

The body-shape fallback relabeled a /v1/messages rejection as acompletion and a list-input /v1/responses
rejection as aembedding, so it now only applies when the logging object carries no known call type

* fix(proxy): share the malformed tools check across tool routes and honor drop_params per entry

* fix(proxy): accept null vector_store_ids, read every named store id in auth, check the responses websocket

* refactor(proxy): leave the responses websocket out of the request-level tool check

* fix(proxy): let a request's additional_drop_params replace the deployment list and keep compact's call type on rejections

* fix(proxy): read router default drop lists and deployment ids in the malformed tools check

* fix(proxy): leave malformed tools to the router when it can pick another deployment

Fallbacks, auto-routers, model strings, comma batches and team model names
let the router pick a deployment after the proxy checks the request, so the
proxy now forwards a malformed tools field there as main does, and only
rejects it when the deployment it checks is the one that serves. Token
counting never reroutes, so count_tokens and input_tokens keep reading the
group they count with. additional_drop_params names are read the way core
reads them, so a list with a non-string entry still names its strings.

* test(integration): cover malformed tools on reroutable models, router defaults and deployment ids

* fix(proxy): resolve malformed tools at the deployment the router picks

* fix(proxy): keep provider-repaired tool schemas, honor fallback_on_unsupported_params, skip cooldown on malformed tools

Empty schemas and JSON-string schemas pass the tools check the way litellm's provider paths already read them. The rejection is a BadRequestError subclass carrying the deployment's provider, so fallback_on_unsupported_params: false keeps the 400, and the router never cools a deployment down for a request litellm rejected before calling it. Adds the audit's pre_call guardrail and cross-provider bridge cells.

* test(integration): expect a 400 for an empty-string tools field on /v1/messages

Real Anthropic rejects tools "" with a 400 on main too, so the case joins the malformed tools test

* fix(router): keep web search routing for tools passed as a tuple

* fix(router): keep a deployment's own tools when drop_params drops a malformed request tools

* test(router): list _merged_tools as covered through the deployment tools merge tests

* fix(router): drop the request's tool settings with its malformed tools when deployment tools replace them

* fix(router): skip a tool whose type is not a string in the web search filter instead of raising TypeError

* fix(prometheus): keep deployment health metrics clean on a malformed tools rejection

* test: type the new malformed tools tests

* test: mark new test locals Final and type kwargs dicts

fix(vector_stores): stop sharing one list across default-constructed registries (#38879)
* fix(vector_stores): stop sharing one list across default-constructed registries

VectorStoreIndexRegistry and VectorStoreRegistry took a mutable list as their
default argument. Python evaluates that once at class definition, so every
registry built without arguments shared one list. The proxy builds one that way
during startup, so an upsert into it leaked into every registry created after,
and into the class default itself.

Default to None and build a fresh list per instance. A caller-supplied list is
still used as given, including an empty one, so nothing that passes its own list
changes behaviour.

Fixes #38874

* test(vector_stores): annotate locals Final and mutate registries through their public API

The leak tests now go through add_vector_store_to_registry and upsert_vector_store_index rather than appending to the registry's list directly, which is closer to how the proxy hits the bug.

* fix(vector_stores): drop the last mutable list default and identity-only tests

refactor(types): replace Any with proven types in 137 files (#44478)
* refactor(types): prove runtime types at harness, search, rag and client boundaries

Replace Any with adapter-validated types in the litellm.agent() harness, the
search provider transformations, RAG ingestion and query, the vector store
pre-call hook and registry, the galileo and opik logging integrations and the
proxy client CLI. Each boundary gets unit tests for well-formed and malformed
payloads.

* chore(typing): prove types at more provider boundaries and restore search transformations

Second pass over a2a, embedding, rerank, image, audio and small provider
modules. Search transformations go back to their previous form because
validating their response bodies would change the proxy status for
malformed upstream bodies from 400 to 500.

* refactor(types): prove types at logging, files, rerank, image, audio and management boundaries

Replace Any with validated or annotation-only types in 37 more files: logging
integrations, token counters, provider files/rerank/image generation/audio
transcription transformations, pass-through logging handlers and management
endpoints. No proxy HTTP status or error type changes.

* refactor(types): prove types at repository, spend, files and router boundaries

Replace Any with repository table accessors, validated mappings and
annotation-only types in 33 more files: Prisma repositories, the enterprise
batch and responses cost checkers, budget reservation, files endpoints,
management endpoints, the policy registry, the adaptive and complexity routers
and the secret managers. No proxy HTTP status or error type changes.

* test(types): run the aiohttp transformation test in-process and cover repository row conversion

The aiohttp chat transformation test no longer starts a server. It feeds the
transformation a response whose json() returns the body under test.

The proxy unit shards now exercise stored model rows whose params are JSON
strings and the object permission create and update paths.

test: move tests/test_litellm root and small trees into tests/unit (#43186)
* ci: run the unit_selection.sh shard files on every event instead of only fork pull requests

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: 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.
