* fix(langfuse_otel): send the completion start time
langfuse_otel never set langfuse.observation.completion_start_time, so
Langfuse showed no time to first token for any call, streamed or not.
The legacy langfuse callback already sends kwargs["completion_start_time"].
Send the same value as an ISO timestamp with an explicit offset.
* fix(langfuse_otel): type kwargs and test against a real span
Type the kwargs of _set_langfuse_specific_attributes as dict[str, Any],
the declared type of model_call_details, so the new completion start time
read adds no unknown-type errors. The tests now check a real SDK span
instead of patching safe_set_attribute, and the parameter is typed.
* fix(otel): send the completion start time from the v2 Langfuse mapper
With LITELLM_OTEL_V2 the langfuse_otel spans come from LangfuseMapper,
which had no completion start time either. Carry the payload's
completionStartTime on LLMCallSpanData for streamed calls, the same calls
that get time_to_first_chunk_seconds, and map it to
langfuse.observation.completion_start_time.
* fix(langfuse_otel): take the logging kwargs as a read-only Mapping
The new kwargs annotation tripped LIT001. Both helpers only read the
logging kwargs, so type them Mapping[str, Any] instead of dict.
* fix(langfuse_otel): time /v1/messages streams from the call start and send the V2 completion start time like the default emitter
* fix(langfuse_otel): time Gemini, Interactions and A2A streams from their first chunk and send the start time as JSON
The native Gemini, Interactions and A2A streams never recorded a first chunk, so with
completion_start_time now sent both emitters showed TTFT equal to latency on them. They
now record it, and Gemini and Interactions take the call's start time like /v1/messages.
Both emitters send the completion start time as a JSON string, the form the Langfuse SDK
and the langfuse callback send, through one serializer.
* fix(langfuse_otel): time A2A streams from the call start and record a cached replay's first event
A2A streams took their start time when the iterator was built, so their latency left out
the work before it. They now use the call's start time like every other route.
Cached /v1/messages stream replays recorded no first event, so their time to first token
fell back to the end time. The replay now records it on the first event it yields.
The tests use the real Interactions config and typed logger hooks.
* fix(a2a): time streamed A2A calls from before the agent card fetch and make the cached replay test clock-free
* test(a2a): type the card fetch test and stop rebinding the seed helper's recorder
* test(otel): expect completion_start_time and cache_hit in the B3 span keys

* test(unit): wait on the work itself instead of fixed sleeps in 21 flaky files
Replace sleeps that raced background logging, cache writes, refreshes and
thread work with either awaiting that work directly (logging worker flush,
the batch logger's flush_queue, the tasks the call spawned, thread joins) or
an Event the test's own fake sets when it runs. Each wait keeps a 5s hang
guard that never decides pass or fail. Tests that need a fake clock, real
sockets, or measure latency are left unchanged, and no production code moves
* test(unit): await the tasks each completion spawns instead of yielding once
The logging tests yielded once with asyncio.sleep(0) so the task that
enqueues the success log could run before the worker flush. That relied
on the enqueue happening before the task's first await. Snapshot the
running tasks around each acompletion call and await the ones it spawned,
so the guarantee holds however many steps sit before the enqueue
* ci: run the unit_selection.sh shard files on every event instead of only fork pull requests

* 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.
