Driving the sad path against a live Atlas cluster showed four cases returning
an empty result set instead of failing: a missing index, a missing database, a
missing collection, and the async path for all three. $vectorSearch reports
none of these as errors, so a misconfigured store looked exactly like a query
that matched nothing, which is the worst shape for this to fail in.
An empty result set is now checked against the index catalogue, which does
report all three correctly, and a store that cannot work says so. The check
costs one extra round trip and only on the empty path, so a search that
returned hits is unaffected.
Atlas also reports a wrong vector path and a dimension mismatch under the same
error code. Both previously surfaced as "index not found", which sent the
reader looking in the wrong place; they are now told apart and each names the
setting that is actually wrong.
65 cases across pipeline construction, response mapping, parameter validation,
client caching, and driver-error translation. The sad-path cases assert on the
message the caller actually sees, since a vector search that fails quietly
returns an empty result set rather than an error.
* fix(guardrails): run apply_guardrail-only providers in logging_only mode
A CustomGuardrail that implements only apply_guardrail inherited the CustomLogger
no-op async_logging_hook, so mode: logging_only never scanned anything and never
recorded guardrail_information. CustomGuardrail.async_logging_hook now routes the
logged request and response through the call type's guardrail translation on
copies and appends the verdict to standard_logging_object.guardrail_information.

Gemini 3.8 Flash launches today with the same promotional pricing, limits,
and thinking settings as Gemini 3.7 Flash, so the gemini/, vertex_ai/, and
bare cost map entries mirror the 3.7 Flash ones. Regression tests lock the
launch prices, the 4096-token cache minimum, and the gemini-3 thought
signature gate in for the new model.
Tamper tests rewrote the last two base64url characters of the signature,
which on roughly 1 in 250 RS256 tokens (1 in 1000 HS256) only touched
padding bits, so the decoded signature was unchanged and still verified.
Corrupt the decoded signature bytes instead.
The fuzzy picker driver sent keys after fixed sleeps, so a slow worker
could receive the filter text before the widget had highlighted the match.
Wait on the widget's highlighted choice instead.

initialize_presidio registers up to three callbacks per guardrail but the
registry only kept the first, so deleting or re-syncing the guardrail left
the post_call siblings serving the old config. The initializer now returns
every callback it registered, the registry tracks primary and siblings per
guardrail id, delete purges all of them from every callback list, and
update pushes the new params into each while siblings keep their stage.
* fix(search): forward search-tool params through the router, complete Parallel AI v1 param mapping
SearchAPIRouter dropped every parameter configured on a search tool, forwarding
only per-request kwargs. Any tool-level setting (mode, max_results, ...) was
silently lost on the way to the adapter, for every search provider.
Also completes the Parallel AI v1 search surface: after_date, fetch_policy,
location and include_domains now nest under advanced_settings instead of being
sent as unknown top-level fields, responses preserve search_id / session_id /
warnings / raw excerpts, and search cost is derived from the request mode and
the provider's reported usage rather than a single flat rate.
* fix(parallel_ai): stop a caller from pricing its own search request
`_parallel_ai_usage` carries the provider's reported usage into cost
calculation. It was only written when the response contained a usage block, so
a caller could pass `_parallel_ai_usage=[{"name": "sku_search", "count": 0}]`
and, whenever the provider omitted usage, bill $0.00 instead of $0.005 — the
value also reached the upstream request body as an unknown field.
The key is now stripped from inbound params and written unconditionally from
the parsed response, so only the provider can populate it.
* fix(parallel_ai): price fast search mode correctly
* test(parallel_ai): fake search at HTTP boundary
* fix(parallel_ai): tolerate null search result fields

tests/e2e/test_junit_properties.py fed a hand-rolled FakeItem to
result_properties and attach_result_properties, both typed pytest.Item,
so uv run basedpyright tests/e2e reported 3 reportArgumentType errors on
litellm_internal_staging and every make check that scopes a litellm/ or
tests/e2e/ Python file failed.
Each test now looks up its own collected Item in request.session.items
and applies the covers marker at run time through request.applymarker,
so the coverage registry's collect-only pass never sees the test ids and
the production functions keep their pytest.Item signatures. No casts, no
ignores.

* fix(proxy): keep passthrough logging metadata and model_info dicts when team callbacks are wired
Passing team callback vars into Logging(kwargs=...) makes get_litellm_params materialize a full litellm_params, where metadata and model_info default to None instead of being absent. Readers that resolve them as .get(key, {}).get(...) then raise, so any passthrough request from a team with logging callbacks 500s once a pre-call guardrail is on, and the router strategy loggers log a traceback per request.
* test(proxy): annotate the closure dicts the passthrough logging tests record into
The LLM Obs callback copied litellm's OpenAI-shaped objects into the span
verbatim, so every field Datadog names differently landed somewhere it does
not read: tool calls kept their nested `function` wrapper instead of DD's
name/arguments/tool_id, tool messages carried no result linking them to their
call, the request's tools were never sent, and prompt-cache counts sat inside
meta.metadata rather than the span metrics its cache dashboards chart.
One rule governs the message mapper: add the fields Datadog declares, and never
destroy content it did not understand. Content collapses to its text only when
it has text, so a content list carrying tool or image blocks rides along
unchanged, and absent messages map to an empty input rather than a fabricated
turn. Tool calls and results are read from both dialects, the OpenAI
`tool_calls` / `role: tool` shape and the Anthropic `tool_use` / `tool_result`
content blocks, so /v1/messages sessions gain tool linking they never had.
Cache counts come from the same owners the savings dashboard uses, so every
provider spelling resolves through one place rather than a second local guess.
The three cache metrics partition the input count: litellm's normalized prompt
total includes both cache categories, as the cost calculator's pricing helper
documents, so the non-cached residual subtracts reads AND writes. Counting a
primed prefix as ordinary input had inflated non-cached usage by exactly the
cache-write count on every priming request.
Correlating a result to its call reads ids and names structurally and parses no
arguments, so a tool call's arguments are decoded once per span rather than
once per pass, and arguments past a size bound ship as the raw string instead
of paying a decode that multiplies memory on hostile compact JSON.
The flat `output_tool_calls.*` metadata copies go away with this: they were a
second representation of a fact that now has its own field on the same span.
Bedrock rejects requests carrying cachePoint blocks for models whose entry in the cost map does not declare supports_prompt_caching (403 "You invoked an unsupported model or your request did not allow prompt caching"). Clients like Claude Code attach cache_control to every request, so any such model behind the gateway failed on every call. The new bedrock_model_accepts_cache_points predicate drops cachePoint emission for map-known non-caching models at all three emission funnels, keeps emitting for unmapped ids (application inference profile ARNs), and skips the gateway injection credit when the tool_config point is not placed.
aiohttp shields its DNS resolution task; when the connector closes it cancels
that child, so the request task sees CancelledError without ever being
cancelled itself. map_aiohttp_exceptions() only caught Exception, so the
BaseException skipped transport mapping, router retries and proxy error
handling, and /v1/responses answered 500 "No response returned".
Catch CancelledError in the mapper, re-raise when the current task is really
being cancelled (Task.cancelling() > 0), and otherwise map it to
httpx.ConnectError so the usual retry, fallback and error mapping apply.
