* fix(responses bridge): keep every reasoning item on a search-only turn

* fix(responses bridge): leave content unset on a search-only turn so replay adds no empty message

* fix(responses bridge): replay tool search items only with tool_search, count replayed tools in the allowlist, keep namespace off guardrails

* fix(responses bridge): honor drop_params for defer_loading and route tool_search to Responses

Under drop_params, defer_loading is dropped when no tool_search tool is sent,
so the 400 it would cause upstream goes away as before. A non-bool value answers
400 without drop_params and is dropped with it. A null tool-level value falls
back to the nested function value. A request carrying a tool_search tool now
bridges to Responses on OpenAI and Azure endpoints even with reasoning_effort
none, since chat completions rejects the tool_search type.

* fix(responses bridge): replay tool search items in output order and count replayed tools in tool policy

Store the ordered output prefix through the last tool search item, reasoning included, so a
second reasoning item no longer makes OpenAI reject the replay. The shared chat-to-Responses
converter now replays tool search items and namespace only when the bridge opts in, so Noma,
the complexity router and guardrail payloads keep their shape. The tool policy guardrail and
the allowlist count replayed tools only when the request can send them.

* fix(responses bridge): forward defer_loading only beside a tool_search tool

defer_loading only means something with tool_search, and backends without it
reject the key (xAI answers 403). A true value with no tool_search tool now
answers 400 naming drop_params and is dropped under drop_params; a false value
there is a no-op and is dropped.

* fix(tool_loop): keep tool search items and namespace between rounds

* fix(responses bridge): check replayed tool search loads when a deployment adds tool_search

* fix(chat): drop litellm response fields before strict OpenAI-compatible providers

A chat reply from the Responses bridge carries provider_specific_fields on the
message and on each tool call, plus reasoning_items. Groq, Fireworks, Mistral
and Together reject unknown fields, so sending that reply back to them as
history failed with a 400 or 422. Strip them in the shared helper and use it
in those providers.

* fix(caching): keep reasoning_items and tool search items on response cache hits

A cached bridge response lost reasoning_items on a non-streaming hit and lost
both reasoning_items and provider_specific_fields (tool_search_items) on a
streamed hit, so the next turn could not replay the search or the reasoning
around it

* test(integration): cover tool search item replay on the chat to Responses bridge

Proxy, SDK, authorization and chaos cells for returning and replaying
tool_search_call and tool_search_output items and the tool call namespace

* test(integration): add response cache twins for the tool search guardrail cells

Each guardrail cell now has a twin where the answer is already in the Redis response cache: a key opted out of global guardrails caches a replay that loads a policy-blocked tool, the same replay without guardrails is cached before block mode sees it, rewrite mode is not served the unrewritten conversation's cached answer, and an allowed replay is served from the cache.

* fix(responses bridge): forward defer_loading beside a client-executed tool_search

The bridge now replays a client tool_search_call and the client's tool_search_output through provider_specific_fields.tool_search_items, so a deferred function beside a client tool_search keeps defer_loading like it does beside a hosted one

* test(responses bridge): pin the client tool_search turn and its replay, streamed and not

* fix(responses bridge): strip nested namespace for strict providers and keep streamed reasoning_items on text replies

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(responses bridge): keep dropping defer_loading beside a client-executed tool_search

Forwarding defer_loading beside a client tool_search made GPT stop with a
search call the chat client has to answer by hand, so a plain question that
used to get tool calls got none. Keep main's behavior of dropping it there.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
