* fix(bedrock): surface a converse-stream 200 that decodes to no events as a 502 instead of an empty turn
* fix(bedrock): quote the body head only when a stream decoded no events
The leftover-bytes error keeps the byte and event counts, the content type and the request id but no longer quotes the first bytes of a stream that already decoded events, since that head is the start of a healthy stream and can hold model output. The anthropic_messages empty-stream warning no longer prints the request's model name.

* 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found superseded by stronger ones kept in this move.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: move tests/test_litellm/llms into tests/unit/llms
Rename-only. Moves the provider tests and the fine-tuning fixtures they
load, mirroring the old paths. Follow-up commits merge, split and wire them.
* test: merge, split and prune the moved llms tests
Merges the Databricks chat transformation tests into the existing unit
file, keeps the tests that need real keys or the network in
tests/test_litellm, deletes the audited tests a stronger unit test
already covers, and points imports at tests.unit.llms.
* ci: run the moved llms tests under their legacy flags
The Vertex AI and All Other Providers shards keep their legacy test-path
for the retained files and add the llm-vertex-ai and llm-other-providers
unit selections. CircleCI gets matching unit jobs.
* test: make the tests/unit/llms directories packages
Adds __init__.py to the moved dirs and drops the legacy ones whose
directories no longer hold tests.
* test: drop script runners and path hacks the llms split left dangling
The __main__ runners in the split openai_like files and the Databricks e2e
runner called tests that now live in the other half of the split or were
deleted. The retained legacy halves also no longer need sys.path edits.
* 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.
* test: keep the Databricks manual e2e runner and fix the SageMaker Nova run path
The Databricks e2e file is a manual script whose main() calls the tests
that were pruned, so pruning them broke the documented run. It is back to
its main version. The SageMaker Nova docstring now points at the file's
real location in tests/local_testing.
* test: keep the job's UNIT_FLAG out of the shard-script tests

* feat(anthropic): placement policy for mid-conversation system messages
Pure functions over the OpenAI-format message list: split off the leading
system run, keep later system messages as role=system at a placement Anthropic
accepts on models flagged supports_mid_conversation_system (after a user turn,
before an assistant turn or the end, never adjacent), and convert them to user
turns in place elsewhere, keeping tool_result first in a merged user turn.
* fix(anthropic): keep mid-conversation system out of the chat completions system prompt
translate_system_message hoisted every role=system message, at any index, into
the top-level system block. On a conversation carrying a mid-session reminder
that rewrites the cached prefix, so the provider re-bills the whole history at
cache-write pricing on every turn (#36559). #36968 fixed this on /v1/messages;
the chat completions path, shared by first-party Anthropic, Vertex, Azure AI
and Bedrock Invoke, still hoisted.
Only the leading system run becomes the system prompt now. Later system
messages go through the placement policy, and anthropic_messages_pt emits a
system message instead of rejecting the role. The caller's message list is no
longer mutated. Tests pin the two-turn prefix invariant across all four chat
configs and both flag states.
* refactor(anthropic): single-source the converted system note
The /v1/messages pass-through and the chat completions path must prefix a
converted system turn with the same operator note.
* test(e2e): prove the prompt cache survives a mid-conversation system reminder on chat completions
Same priming and assertions as the /v1/messages cases, through
/v1/chat/completions with OpenAI-format messages, for first-party Anthropic
and Bedrock Invoke on a flagged (Opus 4.8) and an unflagged (Haiku 4.5) model.
The reminder sits between the assistant turn and the next user turn, the shape
OpenAI-style agent frameworks send, which is the placement the chat path has
to translate.
* test(anthropic): cover the cache_control rebuild shapes and type the test helpers
Codecov flagged the 5m ttl branch and the empty-system path of the wire
builder; both now have a test. Greptile asked for full typing on the new
test helpers.
* refactor(anthropic): read the mid-conversation flag through a public supports_ helper
supports_mid_conversation_system joins the other supports_* helpers in
litellm.utils, so the chat transformation stops importing the private
_supports_factory.
* chore(typing): declare the mid-conversation type aliases with TypeAlias
The Final sweep tightened LIT010, which exempts TypeAlias declarations but
counts a bare alias assignment as an unannotated binding.
* fix(anthropic): let add_code_execution_tool take the pass-through message union
The translator now emits role=system inside messages for models that accept it,
so anthropic_messages_pt returns the pass-through union. add_code_execution_tool
still declared the narrower user/assistant union while only ever reading
content, so upstream's strip_advisor_blocks_from_messages call in between made
the mismatch visible to the type checker.
* fix(bedrock): keep mid-conversation system messages in place on converse path
* fix: ruff format + multi tool_result order + regression test
* fix: satisfy type-discipline gate + update osv ignore for mlflow PYSEC-2026-3865
* fix(bedrock): restore role narrowing in hoisted system loop for basedpyright budget
* test(bedrock): cover mid-conversation system conversion branches
- non-dict guard in _opens_with_tool_result
- in-place conversion without tool context
- str/list cache_control preservation in mid-conversation path
- drop unreachable non-system guard in hoisted loop
* Place type-discipline suppressions on the lines the gate scans
* Narrow hoisted loop to system role so basedpyright sees the right TypedDict
* fix(anthropic): place mid-conversation system runs by their neighbours only
A run after an assistant turn now slides behind the user turn that
immediately follows it, and a run that ends the array or precedes an
assistant turn becomes a user turn in place. No later message can move
an earlier run, so a client that replays the conversation with more
turns appended sends a byte-identical prefix and preserved thinking
blocks keep their binding
* refactor(bedrock): share the converted system note with the anthropic module
Converse imports CONVERTED_SYSTEM_NOTE instead of carrying its own copy
of the same text, and the reordering helpers lose their comments
* test: pin the replayed request prefix across preserved-thinking turns
One test per audited feature, through the real entrypoint: the chat
transformations for anthropic, bedrock invoke, vertex and converse, the
modify_params dummy tool result, dotprompt with unchanged variables, and
Presidio masking against an in-process fake. Each serializes system,
tools and the earlier messages of turn N and N+1 and asserts they match.
The e2e mid-conversation system test imports its content blocks from
models.py again and is marked provider_live
* fix(anthropic): move mid-conversation system placement into prompt_templates
The prompt factory imported the placement helper from the Anthropic provider
package, whose common_utils reads a factory constant at import time, so loading
the factory first raised ImportError. The module now sits next to
anthropic_messages_pt and every consumer imports core utils
A user turn with content [] or None puts no block on the wire, so a system run
anchored to it landed first in messages or behind an assistant turn. Such a run
now converts in place; empty strings and empty text blocks still anchor because
the factory fills them with a placeholder
* fix(anthropic): anchor system messages only on user turns that reach the wire
* fix(bedrock): type the converse system-message helpers over the message TypedDicts
* fix(anthropic): read replayed pydantic messages in the Converse helpers and convert a system run whose assistant follower sends nothing
A history that replays the previous turn as the litellm.Message object
was invisible to the Converse system-message helpers, so a mid-conversation
system stayed between a tool call and its result or reached Converse as
role: system. The helpers now read fields through the shared
message_field and parts_of accessors and drop the local role predicate.
Flagged placement anchored a system run on any assistant follower, but
anthropic_messages_pt drops an assistant turn that puts no block on the
wire (content None, an empty list, an unsigned thinking part), so the
system landed directly before the next user turn, which Anthropic
rejects. Such a run now converts in place. An empty or whitespace text
turn still anchors, since the converter pads it with a placeholder.
* fix(anthropic): treat bridged encrypted reasoning as a vanishing assistant turn for system placement
An assistant turn whose only blocks carry Responses API encrypted reasoning is
dropped by anthropic_messages_pt, so a mid-conversation system run anchored
before it landed directly before the next user turn. The unsignable-thinking
predicate now lives in common_utils and both the factory and the placement
policy consult it.
* fix(anthropic): let an inline thinking part hide separate thinking_blocks in system placement
anthropic_messages_pt skips an assistant turn's separate thinking_blocks as soon
as its content list carries an inline thinking or redacted_thinking part, so a
turn whose inline part is unsigned puts nothing on the wire even when the
separate block is signed. The placement policy now mirrors that rule.

* fix(vertex_ai): translate /v1/responses batch rows through the Responses-to-Chat bridge
Vertex batch uploads treated every non-embeddings JSONL row as a chat
completions body, so a /v1/responses row lost its input and reached GCS
as a blank text part. Route detection now recognizes /v1/responses rows
and bridges them to chat through the same Responses-to-Chat bridge the
real-time path uses. That bridge call moves out of the Bedrock files
transformation into a shared helper both providers call, forwarding the
record's fields as sent, like real time, instead of validating them
against the SDK TypedDicts whose required keys clients omit.

* fix(bedrock): send json_schema as a forced tool on Claude Opus 4.7 and 4.8 Converse
Bedrock rejects outputConfig.textFormat on Opus 4.7 and 4.8 with
"output_config.format: Extra inputs are not permitted", and the AWS
model cards list structured outputs as not supported for both, so
their cost-map entries no longer claim supports_native_structured_output
and json_schema requests fall back to the json_tool_call tool.
Fixes#27846
* test(bedrock): assert Opus 4.7 and 4.8 inline the schema on Invoke, move the native case to Sonnet 4.6
