Trimming the streamed buffer to the retained tail could drop a category
exception phrase that suppresses a later keyword, or the identifier word
of an unfinished sentence that a conditional category pairs with a later
block word. Refuse the cut while either would leave the buffer so the
bounded scan masks and blocks exactly like a scan of the full text

The streaming post-call hook rescanned the whole accumulated choice buffer on every chunk, so scan cost grew quadratically with output length. Keep a bounded per-choice buffer instead: once it exceeds twice the scan context, drop the head when masking the head and tail separately yields the same output as masking the whole buffer, so no pattern, phrase or exception straddles the cut. Detections from the dropped head are kept and merged, deduplicated, into the final log row

A body that serializes litellm_trace_id as null or an empty string carries no identity, so it must not
block the server span fallback. Also mark the nested metadata write as an out-param store

UserAPIKeyAuth.parent_otel_span is Any at runtime (opentelemetry is an optional extra), so the OTel
trace-id fallback must only format an int trace id, otherwise an object that merely quacks like a span
turns the whole request into a 500

When the otel callback is enabled and the client sends no trace or session identity, the request now inherits the W3C trace id of the proxy's server span as litellm_trace_id and metadata.trace_id. The missing_session_id policy and SpendLogs then persist that value as session_id, so a trace in the OTel backend and its row in the Logs UI carry the same id. Explicit x-litellm-trace-id, traceparent, body metadata.trace_id and litellm_trace_id keep priority.

The first cache-enabled litellm-e2e build (211) showed three gaps in the shared provider cache:
Every OpenAI response carries Cloudflare bot-management Set-Cookie headers, and the capture rejected any response with Set-Cookie, so no OpenAI response was ever recorded (179 of 372 misses rejected). The edge already withholds Set-Cookie from the proxy, so drop it before validating and storing instead of rejecting.
The provider prompt-caching tests need fresh provider state: a replayed priming response reports cache creation rather than a cache read, and the TPM test then trips the key limit. Mark both modules provider_live.
TestApiBaseSeam::test_live_mode_returns_none ran inside the cache-enabled runner and saw the shared edge; isolate it from E2E_PROVIDER_CACHE.
The reset job moved from zeroing spend to an atomic decrement of the amount
it cleared, so every batched write now carries {"decrement": <cleared>}
instead of 0. Four tests still pinned 0 and had been failing since, which
also meant they no longer checked the amount at all. Assert the decrement
equals each row's own pre-reset spend, so a wrong amount fails the test.
simple_shuffle logs the selected deployment at INFO whenever a weight set
applies, so the fallback group's selection line lands between the fallback
notice and the success notice and pushed the notice out of the tail-3 window.
Filter it the same way the neighbouring get_available_deployment noise is
already filtered.
Removes the Singulr async_logging_hook and logging_hook overrides so logging_only runs through CustomGuardrail.async_logging_hook: the response scope reaches Singulr as an assistant message instead of a raw ModelResponse dump, a vendor timeout is recorded as guardrail_failed_to_respond, a request-scope block ends the scan, and the sync success callback thread makes no Singulr call.
Decides MCP versus LLM by the proxy logging object's call_type (then the call_type or server-only markers in request_data), never by name, arguments or mcp_tool_name keys a client can put in a chat body. REST /mcp-rest/tools/call pre-scans reach Singulr as mcp_request and a non-mapping arguments value is forwarded as tool_arguments instead of raising.
should_block is a strict bool defaulting to false so a null verdict is an invalid response that block_on_error decides; payload fields drop Any for Sequence, Mapping and AssistantMessage types; metadata carries only the keys present; docstrings and section comments removed per the repo comment policy.
Squash of BerriAI/litellm#37464 (head da298ca7) by @aniket-kardile, adopted onto main: v2 gateway payload contract with request, response, mcp_request and mcp_response scopes, typed payload models, proxy user, org and team metadata forwarded to Singulr, and the logging_only, pre_mcp_call and post_mcp_call modes.
