The sequential version sent one request at a time, so a Redis outage never
reached the concurrency where the failed-tracking alert body actually grows.
This drives the proxy with locust against one model group of three mock
deployments, two failing at order 1 and one serving at order 2, so every
request spends its retries on the failing pair and lands on the serving
deployment through the order-based fallback. Two phases, a healthy baseline
and a CLIENT PAUSE WRITE window, and every request must succeed in both.
Latency, RSS and CPU are reported as p50/p90/p99 per phase rather than
asserted on: RSS and CPU come from psutil on the proxy's process tree, since
a multi-worker proxy serves /metrics from the prometheus multiprocess
collector and that drops the process collector's series. Thresholds stay open
until weekly runs give real baselines.

redis-py's blocking pool reports a saturated pool as ConnectionError chained
from asyncio.TimeoutError. The circuit breaker classified that as a hard
connectivity failure and opened at once while Redis was healthy. Follow the
explicit cause chain so it counts as a timeout and stays behind the
timeout_min_duration gate
Each checkpoint now samples until no new worker has answered for the settle
window, and the growth assertion refuses a worker set that changed between the
warm and after checkpoints instead of comparing only the intersection, so a
leaking worker reached by one checkpoint alone cannot drop out of the gate
The provider budget push runs inside the request success callback, so
awaiting the Redis pipeline there made every request wait for the round
trip. Hand it back to a task whose failure is logged through the breaker
aware logger, so an open breaker stays a debug line and a real Redis error
is one error line instead of an unretrieved task traceback
The release image installs only the proxy extras, and psutil is a locust and mirakuru dev
dependency, so /debug/memory/summary answered with an error and no ram_usage_mb on the e2e
gate. Fall back to /proc/self/statm and /proc/meminfo on Linux when psutil cannot be imported
On the release gate the e2e tests only see the nginx router, and the chart's
ingress sent /debug/memory/summary to the backend catch-all, so the RSS check
measured the backend pod instead of the gateway workers that serve the failing
requests. Render it as an Exact gateway path next to /test, name the host in the
summary response so workers behind one origin never collide on pid alone, and
key the harness readings by (origin, hostname, pid)
Rebuild the shared member table on DataTable so admins can search members by name, email or user id, sort by name, email, role, budget and spend, and filter by role. /team/info now returns each member's user_alias so the table can show a human-readable name

* fix(streaming): keep usage-only chunks from crashing streams with empty stream_options
The usage-only chunk branch in CustomStreamWrapper.chunk_creator indexed stream_options["include_usage"] directly, so a caller passing stream_options={} hit a KeyError that surfaced as MidStreamFallbackError. Streaming mock_response with an admission input_tokens count (#40637) now always emits such a chunk, which made the crash reachable. Reuse the send_stream_usage policy computed at init instead. Also annotate the #40637 test bindings with Final.

A call admitted before the breaker opened could finish while the breaker was
HALF_OPEN and close it before the designated probe reported, so Redis traffic
resumed on a stale answer. The admission now records whether the call is the
probe and only the probe's success closes a half-open breaker.
The cron job lock manager also logged an error every cycle the open breaker
refused its Redis call, one line per job per pod. That refusal is now a debug
line like every other guarded call, while real Redis errors still log at error
A lite login token carried a snapshot of the team's models, aliases and the
user's role taken at login, so team or role changes never reached that CLI
until the user logged in again.
Pull the user, membership and team row loading that the JWT path did inline in
JWTAuthManager.get_objects into a GrantResolver under auth/resolvers, and have
the session token branch of the auth builder resolve the same rows on every
request. A user removed from the team now gets 403, a deleted user 401, and a
demoted admin no longer takes the admin early return.
Team Usage and the main Usage page render every key in the selected
scope with no way to narrow the list. Add a client-side search box
above Key Activity that filters the loaded keys by alias, hash, user
id, or user email, and expose user_id on the daily activity key
metadata so the id is searchable

The sync Redis read now raises while the circuit breaker is open, and the
health state merge caught that as a generic error, skipping the local write
and logging an error on every background health check cycle. Read the shared
snapshot through a helper that treats the refused read as a miss so the merge
falls back to the pod-local copy the way a swallowed connection error already did
* fix(logging): finish response metadata before the sync logging thread reads it
The async and sync client wrappers handed the response to the threaded success handler before computing its cost, call id, and api_base, so that thread inserted into the same metadata dict the request coroutine was still iterating and a finished chat completion turned into a 500 (dictionary changed size during iteration). Metadata is now finalized first, and the merge and header copies snapshot their dicts before iterating.
* fix(logging): snapshot metadata with a dict copy and drop redundant comment

* fix(logging): copy metadata via dict.copy and dedupe Final import

The sync get path was unguarded, logged with a stray format argument, and never fed the
breaker. The sync batch read swallowed the breaker's refusal as an ERROR plus a service
failure event per call, so DualCache dropped its in-memory hits and left batch reservations
behind. record_success closed an OPEN breaker on stale in-flight successes, skipping the
recovery timeout and the half-open probe. The spend counter pipeline re-raised the refusal
into the cost callback, which logged an ERROR and fired the failed-tracking alert per request.
A team or key priority that is not Latin-1 encodable (for example CJK text) was
attached as a response header by the dynamic rate limiter v3 post-call hook, and
Starlette then raised UnicodeEncodeError while writing headers, turning a
successful /v1/messages call into HTTP 500. The header is now omitted for such
values while x-litellm-rate-limiter-version and the v3 rate limit headers are
still attached.

* perf(mock): emit admission-time usage chunk on streaming mock_response
Streaming mock_response chunks carried no usage, so the chunk builder re-tokenized the whole prompt in Python after the stream ended even when budget reservation had already counted it at admission. The mock streaming generators now yield a final usage-only chunk carrying the admission prompt count (same completion count as the non-streaming path). Without an admission count the old tokenizer fallback stays.
* fix(mock): type the mock stream generators and keep the usage chunk on the content stream id
Review follow-up: the usage-only chunk was built with a fresh id, so CustomStreamWrapper switched response_id for the finish-reason and usage chunks. It now copies the content stream id. The generators also get full parameter and return annotations.
