Strategies, pre-call checks, cooldown and fallback helpers, and the auto, complexity and quality
sub-routers now take a RoutingContext instead of the Router, and read the router only through
registry(), settings(), health() and the context's forwarding methods. Router-free helpers move
from router_utils to litellm_core_utils, outside callers of router state switch to entry points,
and the surface allowlist shrinks to the endpoint methods plus the entry points
* refactor(anthropic): rename llms/anthropic/pass_through to llms/anthropic/messages
Move the unified /v1/messages code out of a directory called pass_through, since it is not the
passthrough feature. The inner messages sub-package becomes native, and the Vertex AI partner
model experimental_pass_through package becomes messages. The old packages stay as import shims
that warn once and alias every submodule in sys.modules, so old deep imports still resolve

* fix(router): bound fake-streamed calls by the request timeout, not stream_timeout
A stream=True call that the provider serves as one non-streaming request (Bedrock Converse for json_schema on models without native structured output, tools on some Llama models, ai21) gets no byte until generation ends, so stream_timeout acted as a total-duration cap. The Router now passes timeout and stream_timeout separately to chat completion calls, and completion() applies stream_timeout only when it reads a live stream.
* test(timeout): cover stream_timeout on live streams only and the router's timeout split
* fix(router): cover every fake-stream site and keep the target group's stream_timeout under prompt management
* fix(router): never shorten a fake stream below stream_timeout, and split timeouts on every surface
A faked stream now takes the longer of timeout and stream_timeout, so a caller
who raised stream_timeout to cover a slow fake stream keeps that headroom.
Azure o-series dispatch is mirrored when deciding whether a stream is faked.
text_completion, /v1/messages and /v1/responses through the Router now get
timeout and stream_timeout separately, like chat calls.
* fix(router): report the effective stream timeout, split adapter streams, and cover M365 and Rust messages
* fix(router): report and log the timeout each stream was bounded by
Native /v1/messages and /v1/responses now record the timeout they applied, so
x-litellm-timeout and the cooldown guard read the real limit instead of the raw
request value. A prompt-managed model also passes on only the caller's or its
own timeout, so the target deployment's timeout still wins.
* fix(router): keep the caller's request_timeout on a prompt-managed handoff and report the applied stream limit
* fix(router): give streams answered in one piece the longer limit and accept text timeouts on responses
* fix(router): give /v1/messages and /v1/responses streams answered in one piece the longer limit
* test(integration): cover faked, live and converted stream timeout limits per endpoint
* test(router): regression tests for faked-stream timeouts
* feat(microsoft_365_copilot): add Microsoft 365 Copilot chat provider with OAuth token exchange
* fix(ui): create a credential for credential-only auth types in Add Model
* fix(microsoft_365_copilot): accept max_tokens and list the chat model
* fix(microsoft_365_copilot): register provider model set
* fix(ui): hide other auth types' fields when credential-only types are filtered
* fix(health): do not inherit stored auth settings when a connection test brings its own api_key
* docs(health): restore connection-test inheritance docstrings
* fix(lint): suppress justified provider boundary casts
* fix(lint): satisfy M365 type-discipline gate
* fix(types): eliminate type-check gate regressions
* style: shorten suppression reasons so ruff format leaves them on one line
* refactor(types): drop shared-file type widening unrelated to the Copilot provider
* fix(health): pass caller headers as secret_fields to connection-test probes
* fix(types): type connection-test probe and token counter locally
* fix(lint): drop cast import from connection-test header getter
* chore: remove explanatory comments flagged by review
* fix(proxy): gate OAuth client credentials behind proxy admin
* fix(router): skip cooldown on caller-scoped OAuth auth failures
* fix(router): skip fallback cooldown on caller-scoped OAuth auth failures
* fix(router): type caller-scoped cooldown lookups
* fix(ci): include Microsoft 365 Copilot tests in unit shard
* fix(proxy): keep saved endpoint when test_connection retests a deployment by id
* fix(m365): collapse doubled Graph replies
* fix(m365): preserve trailing system messages
