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.
Wolfi's security database names zlib 1.3.3-r0 as the fix for CVE-2026-85091,
but the newest zlib published to the Wolfi apk repo is 1.3.2-r7. Every
wolfi-base digest, including the current latest, still reports the CVE, so no
base image bump or apk upgrade can clear it and image-scan fails on every PR
touching a Dockerfile or the lockfile, and on the nightly schedule.
Ignore that CVE and its GHSA alias for the zlib apk package only, so a fixable
High in anything else still fails the job.
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.
