Per-row guards in the daily metrics and usage unit flush so a single DB error no longer drops the rest of the batch, plus removal of narrating comments flagged in review
The Noma guardrail sends the conversation to the scanner in `inputs`. It
also forwarded `request_data` whole, which repeats that same conversation
under `messages` (or `input` on the responses API), and attached
`logging_obj.model_call_details`, which repeats it a third time.
For image-heavy calls that duplication is most of the request. A
production scan of a request carrying base64 images measured 100MB total,
of which 94.8MB was `request_data` against 5.1MB of `inputs` - the proxy
was uploading ~95% redundant bytes, and paying to serialize them.
Drop `messages` and `input` from `request_data` and from
`model_call_details`. This is a denylist rather than an allowlist on
purpose: every other key is still forwarded untouched, so a scanner-side
change that starts reading a new `request_data` key needs no matching
release of this hook. The removed keys are ones the scanner never reads -
it takes context only from metadata, litellm_metadata,
provider_specific_header, litellm_session_id/trace_id/call_id, stream,
response/responses ids, and litellm_logging_obj.complete_streaming_response,
all of which still pass through.
The conversation still reaches the scanner in full via `inputs`, so no
detection coverage changes.
Trimming happens before serialization, so the duplicate is never encoded.
Existing payload tests asserted the duplication; they now assert the trim
while keeping what they originally guarded - deep-copy semantics and the
unpicklable-object (uvloop.Loop) regression.
* fix(mcp): scope authorization server issuer

* fix(mcp): keep the bare-origin issuer when no server was named
The scoped issuer must key off whether the request actually carried a server
name. _build_oauth_authorization_server_response rebinds mcp_server_name when
root discovery resolves the single configured OAuth2 server, so gating on the
rebound value also scoped /.well-known/openid-configuration, whose document is
served from the bare origin and whose issuer must stay the bare origin
Adds the named-server regression test for the reported mismatch, restores the
bare-origin assertion, and covers the OIDC document
* test(mcp): type the delegate_auth_to_upstream helper parameter
* refactor(mcp): bind the discovery issuer to a local before building the response

Registry-swap reconciliation used bool(server.url) while registration uses _requires_oauth_discovery, dropping slots for issuer-anchored servers without a url. The preemptive 401 loop awaited discovery before the stamped client_credentials continue, so a deferred discovery failure could 503 requests whose challenge decision never reads metadata
* fix(proxy): cache tag-name registry so unregistered request tags skip Postgres
Request tags are free-form attribution labels, so most have no LiteLLM_TagTable
row. get_tag_objects_batch never cached that absence: every tagged request ran
a find_many that came back empty, and under Prisma pool contention those
per-request queries queued for minutes inside user_api_key_auth.
Cache the bounded set of registered tag names under one aggregate key with the
management-object TTL. Uncached request tags are filtered against it before any
per-tag DB fetch, so unregistered tags cost zero DB reads on a warm path. An
empty registry is cached as a valid answer; DB errors are not cached and fall
back to the per-tag lookup; tables past TAG_REGISTRY_MAX_SIZE cache an overflow
sentinel that disables filtering. Tag create/update/delete endpoints now evict
the registry and per-tag keys and publish cross-worker invalidation (they
previously evicted nothing). The per-tag write-back also gains the management
TTL it was missing, and the hand-built tag:{name} key strings are replaced with
a shared builder.
* fix(proxy): skip per-request end-user DB reads via restricted-id registry
Every request carrying a user id ran get_end_user_object, and with high-cardinality
auto-created end-user rows (hundreds of thousands of ids, all restriction fields
NULL) the per-pod cache missed on nearly every request, so each one paid a Postgres
find_unique that queued behind the Prisma pool during background-job bursts. True
misses were never cached, and unknown ids paid the read twice per request.
Cache the bounded set of end-user ids that carry any restriction (blocked, budget,
region, default model, or object permission) under one aggregate key with the
management-object TTL. When an id misses the per-id cache and is absent from a
usable registry, get_end_user_object returns None with zero DB reads; restricted
ids keep today's fetch-and-cache path. The skip is bypassed whenever
litellm.max_end_user_budget_id is set (default budgets make unrestricted rows
behaviorally distinct from missing rows), validate_end_user_id_in_db is on
(existence checks need the row), or the token carries end_user_max_budget from
custom auth (the row's recorded spend seeds the budget counter). Empty registries
cache as a valid answer, DB errors are never cached, and oversized tables cache an
overflow sentinel that disables filtering. Customer create/update/block/delete now
evict the registry and per-id keys and publish cross-worker invalidation (they
previously evicted nothing), and the per-id write-back gains the management TTL it
was missing so Redis entries no longer live forever.
* refactor(proxy): single generic registry loader with error sentinel and single-flight
Code review follow-ups on the two registry caches. Registry DB errors now cache
the overflow sentinel for a short REGISTRY_ERROR_NEGATIVE_CACHE_TTL window and
log at warning, so a degraded Postgres stops paying the failing registry scan on
every request on top of the per-id fallback. Cold registry loads are single-flight
per worker behind per-registry locks with a recheck after acquire, so a TTL expiry
no longer fans out one full-table scan per in-flight request. The tag and end-user
loaders collapse into one _load_bounded_registry with per-entity fetch closures,
and the triplicated evict-then-broadcast protocol becomes one evict_and_broadcast
helper beside publish_auth_cache_invalidation, shared by the tag, customer, and
project eviction paths.
* chore(lint): suppress fail-safe registry excepts and ratchet BLE001 budget
* docs(proxy): trim registry cache commentary to single-line why docstrings
* fix(lint): move tag fetch return to else block to satisfy TRY300 budget
* fix(guardrails): scan text on /guardrails/apply_guardrail for Azure Content Safety
The two Azure Content Safety guardrails never implemented apply_guardrail, so the
endpoint fell through to the base no-op and answered 200 with the caller's text
echoed back, having scanned nothing.
Implementing that method also flips the proxy's unified-vs-native dispatch, which
would move request traffic off these guardrails' own hooks. Add an opt-out that
keeps every lifecycle event on the native hooks, so only the endpoint changes.
* test(guardrails): cover the remaining native-hook opt-out dispatch sites
Adds regression tests for the parallel post-call path, the MCP post-call hook, and
the policy engine step, so every read of the opt-out flag fails when removed.
Callers can opt into the provider's raw operation response on /v1/ocr with the x-req-format: native header (or req_format in the body) while page-based cost tracking keeps reading usage_info off the normalized response.

Batch retrieval already computed cost/usage on completion, but silently
dropped reasoning tokens and never counted per-line success/failure.
Adds BatchCostUsageResult (replacing bare cost/usage/models tuples) with
successful_requests/failed_requests, and threads reasoning_tokens through
the aggregated Usage. Both surface on SpendLogs the same way batch_models
already does.
Replace _attach_budget_limits_usage, which rewrote the caller's key_info dict, with _budget_limits_with_usage returning a new list. Callers assign the result once. Keeps the response shape and spend-counter read path identical while following the repo's no-mutation rule.
