* fix(vertex_ai): dial the multi-region Live API host for realtime sessions
A realtime deployment with vertex_location us or eu dialed
{location}-aiplatform.googleapis.com, which Vertex does not serve for a
multi-region, so the WebSocket handshake came back 404. The URL builder now
resolves its host through the shared Vertex host resolver, which already
maps us and eu to aiplatform.{geo}.rep.googleapis.com and leaves regions
and global unchanged.
* test(vertex_ai): annotate the realtime multi-region URL tests
* fix(vertex_ai): skip the TLS argument when the realtime api_base is plain ws://
The Vertex realtime session and health-check connects passed the shared
TLS context to every websocket dial, so an api_base the transformation
already maps from http:// to ws:// failed with 'ssl argument is
incompatible with a ws:// URI' before any frame was sent. The OpenAI
realtime handler already skips the argument for ws://; the shared helper
now does the same for the Vertex path
* test(integration): cover the Vertex realtime multi-region host through the proxy
Fourteen cells on the scripted Gemini Live upstream: api_base overrides for
us, eu, us-central1 and global complete a turn; malformed locations are
refused before any dial; a missing location defaults to us-central1; the
realtime health check handshakes the override host and reports a malformed
location without dialing; a refused handshake reaches the client and the
next session connects; twelve concurrent sessions across locations each
reach the upstream once; an upstream outage closes every open session and
the proxy recovers
* test(realtime): type the health-check helpers and flatten the burst order
* test(http_handler): type the realtime TLS test signatures
* test: move the unit half of 126 mixed legacy files into tests/unit
* test: restore litellm globals that moved tests set
* test: finalize migration test cleanup
* test: restore original bodies of moved legacy tests
The move into tests/unit had rewritten 612 test bodies, and some of the rewrites dropped assertions. Each moved test now carries its original body from the legacy file, with only the imports, helpers, fake provider credentials and monkeypatched env it needs to run under tests/unit
test_timeout_streaming goes back to tests/local_testing because it needs the fake OpenAI endpoint server. The image payload fixture moves with its only user, and two tests that leaked global state (a registered model cost entry and queued logging tasks) are now isolated
* test: drop module imports shadowed by restored local imports
* test: assert on LiteLLM output in no-assertion moved tests and isolate leaks
Twenty no-assertion candidates get one assertion on the value LiteLLM returns, with the original lines unchanged. Four tests go back to their legacy files because they only check types or imports, write into the working directory, or cannot assert without a body change
Two moved tests leaked globals into later tests in the same worker, so monkeypatch fixtures now restore the retry-after header parser and the end user cost tracking flags
* test: drain queued logging tasks before the Phoenix span test
The moved Phoenix test counted spans from logging tasks that earlier tests had queued, so the drain fixture moves to tests/unit/conftest.py and both it and the Datadog batch test use it. test_factory_function goes back to its legacy file because its returned wrapper calls the real Assistants API and cannot be asserted on without a body change

* fix(openai/realtime): drop model from upstream URL for intent=transcription
* fix(openai/realtime): keep model on the upstream URL for non-OpenAI hosts
A custom api_base on the openai provider can be a gateway that routes on
the model query param, so the transcription model drop now applies only
to OpenAI's own hosts. xAI's URL is unchanged again
* test(integration): audit realtime transcription upstream URL on a custom api_base
Twenty-two integration cells cover transcription and conversation sessions on every realtime route, the OpenAI SDK sync and async clients, malformed and duplicated query params, unauthenticated and refused upgrades, an unknown model, idempotent spend logging, a twenty-session burst, an upstream outage mid burst, a worker kill, and a proxy restart, each asserting the exact query pairs the upstream received. The scripted upstream now records every websocket upgrade as an observation

* test(e2e): move live-provider legacy tests into tests/e2e
Port legacy tests that exercise real providers into the tests/e2e suites that own them, using the harness (/model/new plus deferred cleanup) and asserting on what the caller receives. Delete legacy tests already covered at equal or stronger strength by e2e, integration or unit tests, and drop the now empty ocr_testing CircleCI job
* test(e2e): address review on the live-provider test move
Assert the SSE error frame a client actually receives when a post_call guardrail blocks a stream, and require a tool call for every requested city before checking the answer. Restore the OCR matrix and its CircleCI job, the Claude Agent SDK streaming test, and test_async_create_batch, since their SDK-level and callback assertions have no equivalent in tests/e2e
* test(e2e): accept both guardrail block shapes on a blocked stream
A post_call block before the first chunk reaches the client as HTTP 400 with either a JSON error body or a single SSE error frame, depending on whether the block surfaced as an exception or an error chunk. Assert the policy message is present and the blocked output is absent in both
* test(realtime): restore direct SDK realtime tests against OpenAI
The e2e realtime tests go through the proxy and the remaining SDK tests either mock the upstream or assert less, so keep the direct litellm._arealtime tests with and without intent, and TestOpenAIRealtime::test_realtime_connection, in place
* test: make realtime and Nova stream checks deterministic
The direct SDK realtime tests now fail on a refused connection instead of skipping. The with-intent test asserts OpenAI rejects the exact intent value sent, which only happens when the intent is forwarded. The Nova /v1/messages stream test asserts stream structure, stop reason and usage instead of model wording
* test(realtime): own intent forwarding with a unit test instead of a live rejection
Assert litellm._arealtime passes the intent query param into the OpenAI realtime websocket URL, which is the behavior LiteLLM owns, and drop the live test that depended on OpenAI's rejection wording
