The pre-call hook passed the proxy's whole per-request metadata dict into the
request identity, so proxy-owned siblings such as requester_ip_address were
promoted alongside the caller's keys. Only the requester_metadata mapping is
read now, keyed under its wrapper, which keeps the default allowlist behaviour
unchanged

Strip only the proxy's requester_metadata. wrapper from an allowlisted key so
requester_metadata.trace_id lands as litellm.metadata.trace_id while other
dotted keys keep their full path and cannot collide on a shared leaf name

baggage_metadata_keys entries such as requester_metadata.trace_id now resolve the caller's nested metadata.trace_id and stamp it on the LLM-call span as litellm.metadata.trace_id, in both the OTEL v2 logger and the legacy OpenTelemetry callback. Nested metadata mappings are flattened to dotted paths, only allowlisted leaves are promoted, and the requester_metadata blob itself is never promoted

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

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.
