Backport of #45108 to stable/1.105.x.
Cherry-picked from 5cd1126870 (main).
Prerequisite for #45151: adds the claude-haiku-5-5 entries that fix corrects. Cost-map conflicts resolved by appending the new entries.
The #46342 backport carried block_binding through every subclass of the
Anthropic and Bedrock Invoke configs, so Bedrock Mantle, Claude Platform and
OpenAI-compatible Anthropic endpoints started sending it. Each of the six chat
and messages configs now opts in by exact class, and the Bedrock Invoke
display updates and clear_thinking rebuilds carry block_binding only when the
config opts in. Every other config sends the same thinking as 1.105.1
* fix(proxy): authorize the public name of a team-scoped model on batch retrieve/cancel
A unified batch id resolves to the deployment's internal model_name
(model_name_{team_id}_{uuid}), which is in no key or team allowlist, so
authorize_model_for_key always denied and team keys got 403 retrieving or
cancelling their own batches. Authorize against model_info
team_public_model_name when the resolved deployment is team-scoped, falling
back to the resolved name otherwise.
Fixes#46958
* fix(proxy): authorize team-scoped batch models by their public name on both auth paths
* fix(proxy): accept the owning team's public name for its own team deployment on every auth path
Managed batch, file, fine-tuning, vector store, character and video ids resolve to the
team deployment's internal name again, so teams that granted the internal name keep access.
The model access check now also accepts the owning team's public name and its legacy team
aliases for that internal name, and only when the caller's team owns the deployment.
* fix(proxy): match a team deployment's public and alias names against the caller's own grants

* fix(anthropic): treat adaptive thinking as enabled when mapping response_format
is_thinking_enabled only recognised thinking.type=enabled, so a request that
paired thinking.type=adaptive with response_format took the synthetic JSON
tool path with a forced tool_choice, which Anthropic rejects alongside
thinking. The same check also gates the Bedrock Converse and Databricks
forced tool_choice downgrades, so they now see adaptive thinking too.
* fix(anthropic): keep signed thinking blocks with empty text on chat completions
Models that default to display: omitted return signed thinking blocks whose
text is empty, and Anthropic rejects the next turn when they are not replayed
unchanged. is_unsignable_thinking_block dropped them along with unsigned
blocks, and the inline content path required non-empty text, so a tool-use
turn on Opus 4.7+ or the 5 families lost its thinking blocks and 400ed on the
tool-result turn. Only a missing signature now drops a block, and the
mid-conversation system placement mirrors that rule. The /v1/messages strip
helper is left to #41362.
* fix(anthropic): skip the thinking-strip retry when block_binding asks for an error
The /v1/messages retry loop strips thinking blocks and resends on any
invalid-thinking 400, including the binding mismatch a caller opted into
with thinking.block_binding.prefix_mismatch_behavior: error. The retry
decision now sees the request body and surfaces that 400 instead of
overriding the caller's choice. #42888 covers the litellm_params side.
* fix(bedrock): carry thinking.block_binding through the Invoke thinking rebuilds
Bedrock Invoke rebuilt the thinking param from scratch when display: updates
was requested, on both the /v1/messages and chat completions paths, and the
legacy enabled-to-adaptive translation plus the clear_thinking injection did
the same, so thinking.block_binding never reached Bedrock. Every rebuild now
spreads the caller's thinking and only overrides the keys it owns, and
AnthropicThinkingParam types block_binding. The thinking-binding-controls
beta was already on the Bedrock allowlist.
* fix(anthropic): keep forcing the response_format tool under adaptive thinking
This reverts ad9e861ae7. Anthropic, Bedrock Invoke and Vertex all accept a
forced tool_choice next to thinking.type=adaptive and only reject it with
type=enabled, so counting adaptive as enabled fixed no live failure. It did
drop the forced JSON tool, so Claude answered response_format requests in
prose, and it downgraded a required tool_choice to auto on Bedrock Converse
* test(e2e): drop the adaptive thinking tool round trip case
With adaptive thinking the model often skips thinking on the weather prompt, so
turn 1 carries no signed empty block and the case fails before the replay it is
meant to cover. Anthropic also answers the replay with a 200 whether or not the
block is forwarded, so the case could not tell the fix from main. The factory
unit tests pin the outgoing shape instead
* fix(anthropic): only skip the thinking-strip retry for a binding mismatch 400
prefix_mismatch_behavior: error asks Anthropic to reject a block bound to
another conversation. It says nothing about unrelated bad blocks such as a
null signature, so those still get the strip-and-retry self-heal. Also trims
the empty-thinking docstrings to what the code guarantees and types the new
test parameters
* refactor(anthropic): narrow thinking fields with the mapping validator instead of typing.cast
typing.cast is banned by the strict ruff gate (TID251), so the three new casts pushed that rule one over its merge-base count. The existing pydantic mapping validator gives the same typed view without an unchecked cast, and it now has a generic name since it is no longer only used for Claude Code payloads
* refactor(anthropic): read thinking settings through the validated mapping so basedpyright stays at its merge-base count
The Bedrock clear_thinking rewrite still narrowed with a cast and an untyped dict fallback, which added two reportUnknownVariableType errors. It now uses the same pydantic mapping validator, made public for that reuse, and the retry hook validates the request body itself so the handler passes a typed dict instead of an untyped one

(cherry picked from commit f470e418ea)
The request-side sanitizer on /v1/messages dropped every thinking block whose
text is empty, even with a valid signature. Claude Opus 4.8 / Fable 5 / Fable 5.1
return exactly that shape by default (thinking.display omitted): the signature
is the preserved reasoning. Replaying the assistant turn as returned therefore
lost the model's reasoning on every multi-turn request, silently (the provider
answers 200 without it), and left preserved-thinking enforcement
(thinking.block_binding) nothing to bind.
Anthropic accepts an empty thinking block that carries a signature and binds it
to its prefix; only an empty block with no signature (the LIT-6357 case, a turn
a non-Anthropic model served through the bridge) is rejected with "each
thinking block must contain thinking". Use the signature-aware predicate
is_empty_unsigned_thinking_block, which #38809 already applied on the emit
side, for the request side too. The unsigned case is still dropped.

* fix(proxy): stop queued registry read-throughs spending the resync budget
RegistryReadThrough.attempt serializes misses behind one lock, but every
request that was queued behind the first one still spent a unit of the
20-per-5s resync budget and re-ran the DB resync, even though the first
request had already loaded the object. A burst of more than 20 requests
for a model created on another worker therefore exhausted the budget and
the rest got 400 "Invalid model name".
attempt now checks whether the key is already loaded once it holds the
lock and returns early without touching the budget. Models check the
router's model names and deployment ids, guardrails and agents reuse
their existing registry lookups.
* test(proxy): gate the queued read-through test on events and cover each registry's loaded check
The queued-requests test now holds the first resync on an asyncio.Event instead of
a timed sleep and records calls in a recorder with tuple and frozenset state. New
tests show the model, guardrail and agent read-throughs each answer an object that
is already loaded without reading the database, so rewiring any registry's loaded
check now fails a test
* test(proxy): keep the queued read-through recorder inside its test and type the agent registry fixture

* feat(strands_decider): call a Strands Decider on an AgentCore runtime ARN

* fix(decisions): keep APIConnectionError for unreachable deployments on every provider
`_map_upstream_exception` now maps a status `_handle_error` synthesized for a
non-HTTP failure to `APIConnectionError` before `exception_type` runs, so a
Perplexity (openai-compatible) deployment that cannot be reached no longer
answers `InternalServerError` where main answers `APIConnectionError`.
Audit cells: the unreachable-deployment integration cell is parametrized over
the five providers, OpenRouter connection failures are pinned on chat, stream,
embeddings, decisions and the SDK, a deployment whose provider has no decisions
config gets the 400 naming every supported provider, and a unit cell pins the
mapper alone. The first docstring sentence of the five translation bases is
dropped.

System One requests to openai/ models are translated to OpenAI's Decisions shape on the way out and OpenAI's answers are translated back, so both /v1/systemone and /v1/decisions can route to gpt-6-luna.
(cherry picked from commit b94bbbc318)
* refactor(decisions): move the OpenAI wire translation into llms/openai
(cherry picked from commit d209a85076)
* feat(decisions): route both request formats through a shared decisions IR
System One and OpenAI-format bodies now convert to one internal representation, and each provider translates it to its own wire format. OpenAI deployments receive the caller's messages, images, names, typed choice values, level descriptions and safety_identifier unchanged. System One providers return a 400 for image input. Cached and cache-write tokens are priced on both response shapes, and provider response extras survive the round trip.
(cherry picked from commit 0dd207fde1)
* fix(decisions): keep provider fields inside System One answers
(cherry picked from commit 1348de864f)
* fix(decisions): load on Python 3.10 and 3.11 and bill cached tokens once under custom pricing
Decisions IR dataclasses used a mappingproxy default, which is only hashable from Python 3.12, so import litellm failed on 3.10 and 3.11. Decisions usage now reaches cost_per_token as a Usage with prompt_tokens_details, so custom pricing no longer adds cached and cache-write tokens on top of input_tokens that already include them
(cherry picked from commit 39012f1c22)
* fix(decisions): honor litellm OpenAI key and base settings for the openai provider
OpenAI decisions now resolve the key from litellm.api_key, litellm.openai_key, then OPENAI_API_KEY, and the base from litellm.api_base, OPENAI_BASE_URL, then OPENAI_API_BASE, matching other OpenAI calls. Providers own their configured key and base lookup through the endpoint config.
(cherry picked from commit e465919004)
* test(decisions): clear every OpenAI base setting in the proxy OpenAI deployment test
(cherry picked from commit a2951b318d)
* fix(decisions): send OpenAI instructions for System One questions without them and reject single-option questions
(cherry picked from commit e4081f77c6)
* fix(decisions): return guardrail_information on OpenAI-format decisions when requested
Backport of the #45184 and #45214 guardrail fix.
Cherry-picked from 855f0bb765 (litellm_systemone_endpoint) as merged into #45214 at c19ada66ed (litellm_openai_decisions_provider).
