afd7917b8b fix(mcp): separate issuer identity from anchoring so carry-forward keeps endpoints
Making the in-memory issuer reflect a trust-on-first-use discovered value fixed
the registry/row token-identity drift, but it overloaded a single field: the
carry-forward gate keyed on issuer truthiness as a proxy for "endpoints are
anchored to a pinned issuer, fail-closed". A discovered issuer is truthy yet not
anchored, so a resource-rooted server that had learned its issuer would drop its
last-known-good endpoints on a transient discovery blip instead of carrying them
forward.

Anchoring is now a first-class property rather than a proxy. MCPServer carries
issuer_is_anchored, set at both build paths from the single _uses_issuer_anchor
definition (a pinned issuer on a discovery auth type). issuer stays the identity
value used by the token-identity tuple and the serializers; issuer_is_anchored is
the provenance value the carry-forward gate reads to decide fail-closed. The two
properties can no longer be conflated, so a discovered issuer keeps its
resource-rooted endpoints carrying forward while a pinned issuer still fails
closed.

Regression tests pin both directions: a discovered-but-not-anchored server
restores its endpoints on a discovery blip, an anchored server does not, and the
build sets issuer_is_anchored true only when the issuer is pinned

feat(complexity_router): enable session_affinity by default (#33500)
Pin a session's first-turn model for the rest of the session by default
instead of reclassifying every turn. Keeps multi-turn sessions on a single
model, preserving provider prompt caches and avoiding cross-model
conversation-history errors (e.g. Anthropic rejecting a thinking block
produced by a different model). Requests without a resolvable session_id are
unaffected. Set session_affinity: false to opt out.

feat(cli): add lite up/down to ambiently route Claude Code through the proxy (#33231)
* feat(cli): add `lite up`/`lite down` to ambiently route Claude Code through the proxy

Patches ~/.claude/settings.json in place (env.ANTHROPIC_BASE_URL + apiKeyHelper
via `lite auth print-token`) so any `claude` session started afterward, from
any terminal, routes through the local LiteLLM proxy with no wrapper command
needed, unlike the existing `lite claude` subprocess-exec approach. Backs up
the original file first and restores it on Ctrl-C/SIGTERM, or via `lite down`
after an unclean exit. Cursor is not supported: no equivalent file-based config
to patch.

* feat(cli): add lite autoroute to QA complexity-based auto-routing against a real proxy (#33249)

* feat(cli): add lite autoroute to QA complexity-based auto-routing against a real proxy

Lets a customer try litellm's complexity_router against models they already
have on their existing, unmodified production proxy, with no config.yaml
edits and no new infra. lite autoroute configure discovers accessible
models via /model_group/info and walks through tier assignment (plus
optional LLM classifier / semantic matching / adaptive selection); every
referenced model becomes its own litellm_proxy/<name> deployment forwarding
back to the real proxy with the real key, so every actual call, routed
completions, classifier calls, embedding calls, still lands on their real
proxy. lite autoroute up launches that generated config as an ephemeral
local proxy, patches ~/.claude/settings.json to point Claude Code at it, and
streams routing decisions live; Ctrl-C/SIGTERM (or lite autoroute down
after an unclean exit) restores everything.

Also adds lite model-groups list (a thin CLI wrapper over the existing
ModelGroupsManagementClient), and generalizes up.py's settings-backup/restore
helpers to take explicit paths so this feature can reuse them instead of
duplicating the logic.

Depends on litellm_lite_up_down (#33231) for that generalization.

* feat(cli): allow multiple models per autoroute tier

complexity_router already supports a pool of models per tier (randomly
picked per request; adaptive mode specifically needs a pool to choose
within), but the configure wizard only ever let you assign one. Tiers are
now a tuple of model names; the wizard prompt accepts comma-separated
indices to pick more than one per tier.

* feat(cli): fuzzy model picker and auto-route Claude Code to autorouter

Numbered-index selection didn't scale past a handful of models, so switch
the tier picker to InquirerPy's fzf-style fuzzy search. Also set
ANTHROPIC_DEFAULT_{SONNET,HAIKU,OPUS}_MODEL to "autorouter" in Claude
Code's settings, since Router resolves auto-router deployments by literal
model name with no wildcard support, so a "*" catch-all model_name would
never match real traffic.

* feat(cli): allow installing lite CLI from source via LITELLM_CLI_REF

Lets testers try an unreleased branch's CLI changes with the same
curl-piped installer, instead of waiting for a PyPI release.

* fix(ci): modernize type hints to clear ruff strict-rule budget

* fix(ci): bump httplib2 and setuptools to patched versions

Clears osv-scan findings for PYSEC-2026-3444 and PYSEC-2026-3447.

* fix(cli): write autoroute's secret-bearing files with mode 0600

commands.py wrote config.yaml (embeds the real proxy key) and Claude
Code's settings.json (embeds the ephemeral proxy's master key) with
plain open(), landing at the umask-derived default (commonly 0644)
until a later chmod call caught up. That window, and the missed case
where settings.json already exists (chmod never ran at all there),
left a credential-bearing file readable by another local account.

secure_create() fixes the mode via fchmod on the fd before any
content is written, covering both the brand-new-file and
already-exists cases, and commands.py/wizard.py now route their
sensitive writes through it.

* docs(cli): warn that a stale Claude Code session can leak to a squatted port

lite autoroute up's master key is embedded statically (unlike lite up's
apiKeyHelper, resolved per request), so a Claude Code session still
running after teardown keeps sending it, along with prompt content, to
a now-unbound loopback port that another local account can bind. This
is the same one-time-patch tradeoff lite up already accepts, just with
a static secret instead of a re-resolved one -- document it in the
README's Caveats section and surface it in the teardown message itself.

* fix(cli): address greptile review feedback on autoroute PR

- terminate the ephemeral proxy child process when its health check
  fails, instead of leaking an orphaned, unrecoverable process bound
  to the port
- replace bare assert isinstance checks (no-ops under python -O) with
  click.ClickException in the model-groups list and configure wizard
  code paths
- close launch_proxy's log file handle once the child process has
  inherited its fd, instead of leaking it
- add build_generated_proxy_config to config.py's __all__

* fix(cli): close TOCTOU window in lite up's settings backup write

write_backup wrote the backup (which can embed the original
apiKeyHelper/settings content) with plain open() + a chmod call after
the fact -- the same permissive-until-corrected window already fixed
for autoroute's config.yaml and Claude settings writes, and missed
entirely when the backup file already exists with broader permissions.

Moves secure_create (atomic-enough 0600 via fchmod before any content
is written) to up.py, the module both lite up and lite autoroute
share, and has autoroute/process.py import it from there instead of
keeping its own copy.

* fix(cli): refuse autoroute up when a stale backup exists from a crash

The pid-record check only catches a still-live duplicate process; a
SIGKILL'd `up` leaves no live pid but does leave AUTOROUTE_BACKUP_PATH
behind. Without this guard, a fresh `up` overwrote that backup with
the currently-patched Claude settings instead of the true originals,
so `down`/Ctrl-C would restore the wrong content permanently. up.py's
`lite up` already guards the analogous case; mirror it here.

* fix(cli): bind the ephemeral autoroute proxy to loopback only

proxy_cli.py defaults --host to 0.0.0.0 when not passed explicitly.
launch_proxy never passed it, so the ephemeral proxy -- despite every
base_url in this module being built from 127.0.0.1 -- was actually
reachable from other hosts on the network, including its
unauthenticated-until-config-lands routes before the master key is
wired in.

* docs(cli): show curl install for the autoroute QA flow

Points readers at scripts/install-cli.sh's curl one-liner instead of
assuming uv/pip is already set up, and documents the LITELLM_CLI_REF
override for trying an unreleased branch or commit.

* fix(cli): surface a clean error on an empty or corrupt autoroute config

A configure run killed between secure_create's O_TRUNC and the write
completing leaves an empty config.yaml on disk. The next up read that
via yaml.safe_load (None) into the generated-config TypeAdapter
uncaught, surfacing a raw pydantic.ValidationError instead of pointing
the user back at `lite autoroute configure`.

* fix(cli): bind lite up's apiKeyHelper to the proxy it was started against

_ensure_fresh_login only checked token freshness, not which proxy the
cached token belonged to, and resolve_api_key_helper built a bare
`lite auth print-token` command with no --base-url. A user logged into
proxy A who ran `up --base-url proxy-b` (or LITELLM_PROXY_URL=proxy-b)
would silently get proxy A's real token wired into Claude Code's
apiKeyHelper; since apiKeyHelper is invoked bare, print-token's
existing origin check never engaged, so proxy B -- attacker-controlled
or not -- received every subsequent request's Authorization header
carrying proxy A's credential.

_ensure_fresh_login now requires the cached token's base_url to match
before treating it as usable, forcing a fresh login for the selected
proxy otherwise. resolve_api_key_helper now takes that base_url and
threads it through as an explicit --base-url, so print-token's
existing (but previously unreachable in the apiKeyHelper flow)
base_url_explicit check actually enforces the match at request time
too.

* fix(cli): surface clean errors instead of raw tracebacks in lite up/down

load_json_or_empty and read_backup both delegate to pydantic's
validate_json, which raises ValidationError on invalid JSON or a
non-object root -- neither up() nor down() caught it, so a corrupt
settings or backup file surfaced an unformatted Python traceback
instead of a clean CLI error. Both now convert to UpError, and down()
(previously uncaught entirely) and up()'s teardown path now handle it.

restore_claude_settings also gained a parent.mkdir guard before
rewriting CLAUDE_SETTINGS_PATH: if ~/.claude/ was removed while `lite
up` was running, the restore would crash before deleting the backup
file, permanently stranding it and breaking every future `lite down`.

* docs(cli): call out env-var auth for autoroute commands

* fix(cli): clean up leaked proxy and surface clean errors in autoroute

Three related gaps, all following an UpError getting raised somewhere
that wasn't catching it yet:

- up() left the just-launched ephemeral proxy running with no pid
  record if load_json_or_empty/write_backup/secure_create raised after
  the health check passed, mirroring the existing ProcessLaunchError
  cleanup for the health-check-failure branch.
- _teardown() didn't catch restore_claude_settings raising UpError
  (e.g. a corrupt backup at stop time), which would otherwise escape
  to Click as an unhandled error in the normal-exit path, or print
  "Error in atexit" in the atexit path. up.py's own _restore_once
  handles the identical case the same way.
- read_pid_record let a corrupt PID file surface a raw
  pydantic.ValidationError instead of a clean message, and did so in
  down(), the command specifically meant for crash recovery. down()
  now clears an unreadable pid record and continues cleanup instead of
  aborting, since a corrupt pid file must never block the one command
  meant to recover from exactly this kind of crash.

ad73f3a7a2 fix(mcp): keep issuer provenance consistent when it changes or is discovered
Two lifecycle gaps let the issuer trust anchor drift out of sync with the
endpoints it governs. Changing or clearing a previously pinned issuer left the
authorization_url and token_url that were resolved under the old issuer in the
row, so clearing the anchor could revive stale, possibly untrusted endpoints
instead of re-discovering. And a build that discovered an issuer
trust-on-first-use persisted it to the row while the returned in-memory server
kept the issuer unset, so the registry and the row disagreed and the per-user
OAuth token identity, which includes the issuer, differed between that build and
the next rebuild and forced a spurious re-auth.

update_mcp_server now treats a change to a previously pinned issuer the same as a
url or auth_type change and clears the auth-flow-scoped endpoint fields that were
resolved under it. The trigger fires only when an issuer was already pinned and
is now changed or cleared, so establishing one for the first time, including the
trust-on-first-use discovery write-back, does not wipe the fields it just
resolved.

Both build paths, build_mcp_server_from_table and load_servers_from_config, now
construct the server with effective_issuer = manual_issuer or the discovered
issuer, skipping an origin-fallback guess exactly as the persistence does, so the
in-memory object always reflects what the row will hold.

Regression tests pin each case: clearing and re-pointing a pinned issuer clear
the stale endpoints, a first-time establish preserves the discovered fields, and
a build reflects the discovered issuer while an origin-fallback guess is not
reflected

fix(complexity_router): return empty dict from _classifier_call_metadata when metadata is absent (#33452)
* fix(complexity_router): return empty dict from _classifier_call_metadata when metadata is absent

The LLM classifier reads request_kwargs.get("litellm_metadata"), but the proxy stores request metadata under "metadata", so this returned None. _classifier_call_metadata then passed None straight through to the classifier acompletion call, which assumes a dict and blows up with 'NoneType' object has no attribute 'update'; the router swallowed it and silently fell back to heuristic scoring, so the configured LLM classifier never ran. Returning an empty dict keeps the classifier call well-formed.

* test(e2e): cover complexity-router LLM classifier routes over the proxy

Add a live e2e regression for the complexity auto-router: a lexically simple but hard prompt ("Is P equal to NP?") is routed by the LLM classifier to the higher-tier anthropic backend, read back from the spend log's model. Before the metadata fix the classifier silently crashed and the router fell back to heuristic SIMPLE scoring on the openai backend, so this test fails pre-fix and passes post-fix.

032a2f2d76 fix(mcp): enforce the issuer trust anchor at every endpoint adoption site
When an admin pins an issuer, RFC 8414 section 3.3 makes that issuer the sole
authoritative source of the authorization and token endpoints, so a compromised
or misconfigured upstream cannot smuggle a token endpoint by echoing the pinned
authorize URL. The first cut enforced that only on the database build path; the
carry-forward, persistence, config-load, serialization and sanitization paths
could still restore or emit upstream-derived endpoints for an issuer-anchored
server, which is the class of gap the review flagged.

Every site now routes through one predicate. _endpoints_yield_to_issuer returns
all-None whenever the issuer is the anchor, so both build paths,
has_all_upstream_oauth_fields, needs_discovery and the endpoint merge defer to
the issuer. _carry_forward_resolved_oauth_endpoints carries only scopes for an
issuer-anchored server and fails closed on endpoints.
_persist_discovered_oauth_endpoints skips endpoint writes under the anchor. The
two table serializers round-trip the issuer and both non-admin sanitizers redact
it. Scope selection stays resource-driven per the MCP authorization spec:
_fetch_issuer_anchored_oauth_metadata takes endpoints from the issuer document
and scopes from the resource document.

The OAuth metadata resolution and corroboration gating for the database build
path move into _resolve_table_oauth_metadata so build_mcp_server_from_table
stays within the cyclomatic-complexity budget without changing behavior.

Regression tests pin the invariant at each site: the issuer overrides stored
endpoints even when they are populated, carry-forward does not restore endpoints
under the anchor, persistence does not write endpoints under the anchor, a url or
auth_type change clears stale issuer-scoped fields even when resubmitted
unchanged, the Azure heuristic stays reachable under a required issuer, and
anchored metadata takes endpoints from the issuer while scopes come from the
resource

b3af125078 fix(mcp): keep scopes resource-driven under a pinned issuer
The issuer anchor is for the token/registration endpoints only (the RFC 9700
mix-up). Scope selection stays resource-driven per the MCP authorization spec
Scope Selection Strategy: _fetch_issuer_anchored_oauth_metadata now validates
the issuer document (RFC 8414 §3.3) for the endpoints and separately fetches the
resource's advertised scopes (WWW-Authenticate challenge, else RFC 9728
scopes_supported) for the scope value, instead of using the issuer document's
own scopes_supported. The resource can influence only the requested scope, which
the authorization server and user consent bound (RFC 6749 §3.3), never the token
endpoint.

031922eec6 feat(mcp): discover-by-default issuer (trust-on-first-use) + stale-clear on url/auth_type change + UI
Discover the issuer from the upstream and persist it trust-on-first-use (fill-empty-only,
frozen thereafter), so admins do not have to type it; an admin-configured issuer always wins
and is never overwritten. Re-pointing the server url now clears the discovered issuer and
endpoints (matching the existing auth_type-change clearing) so a new upstream re-discovers
instead of anchoring on the previous upstream's issuer. Adds the issuer to the per-user OAuth
token identity so re-pointing it purges stale tokens. Surfaces the issuer as an optional,
auto-discovered, overridable field in the create and edit MCP server forms.

C901 gate shows +1 vs staging; that is inherited from the #33317 stack base (delta 0 against

8e73ff057f feat(mcp): issuer-anchored OAuth discovery (RFC 8414 §3.3) as the trust anchor
Adds an admin-configured issuer to MCP servers. When set, OAuth metadata is
fetched from the issuer's own origin and adopted only when the document
self-attests that same issuer (RFC 8414 §3.3), making token_endpoint,
registration_endpoint, and scopes authoritative for the pinned issuer instead
of a document the MCP resource server chose. This closes the mix-up where a
compromised resource echoes a pinned authorization_url to smuggle its own
token endpoint and inflated scopes past the corroboration gate. Discovery is
same-authority against the issuer origin, fails closed on a §3.3 mismatch, and
does not fall back to resource-rooted discovery. Rows without an issuer keep
the existing corroboration-gate behavior unchanged.

Backend + schema only; UI field and live-proxy proof follow.

e4a6516b49 fix(mcp): keep scope selection resource-driven, not authorization-server-driven
Reverts the over-correction that restricted a pinned-authorization_url server's
discovered scopes to the authorization server's own scopes_supported. Per the MCP
authorization spec Scope Selection Strategy and RFC 9700 §2.3, the scopes a client
requests are resource-driven: the WWW-Authenticate 401 challenge scope, else the
RFC 9728 protected-resource scopes_supported. The authorization server's RFC 8414
scopes_supported is a non-exhaustive capability list (the server MAY omit supported
scopes) and is never the selection source; scope inflation by a compromised resource
is bounded by the authorization server and user consent (RFC 6749 §3.3), not by the
client restricting the request. The corroboration gate now rejects only the
uncorroborated token_url/registration_url (the RFC 9700 endpoint mix-up) and leaves
scopes untouched. Removes the now-unused authorization_server_scopes field.

feat(guardrails): forward optional metadata on POST /guardrails/apply_guardrail (#33067)
Clients calling the standalone apply_guardrail endpoint had no way to pass
per-request configuration to custom guardrail implementations. This adds an
optional metadata field to ApplyGuardrailRequest and forwards it to
CustomGuardrail.apply_guardrail via request_data, only when the client sends
it. The messages guard is aligned to the same is-not-None semantics so an
explicitly-sent empty list is forwarded instead of silently dropped.

The Admin UI's Guardrail Test Playground gains an optional Metadata JSON
input (validated client-side) wired through applyGuardrail in networking.tsx,
so parameterized guardrails can be exercised from the dashboard.

Tests cover metadata alone, metadata with messages, explicit empty values,
the omitted-field passthrough, and the UI panel's parse/error behavior

fix(logging): stop pinning large request payloads past request end (#33455)
Three process-lifetime retention points kept full request payloads
(messages included) alive after the request finished. Under bursts of
large-token traffic (~73K tokens/request mean) this presented as
stepwise RSS growth that never returned to baseline, ending in OOM:

1. Logging.pre_call/post_call stored their entire locals() (messages,
   the Logging object, complete_input_dict) in the module-level
   litellm.error_logs dict, pinning the most recent request's payload
   per worker forever. Nothing reads that dict; the writes are removed.

2. LLMCachingHandler.request_kwargs kept litellm_logging_obj inside the
   stored kwargs while the handler itself hangs off
   logging_obj._llm_caching_handler, closing a reference cycle
   (Logging -> LLMCachingHandler -> kwargs -> Logging). Cyclic payloads
   are only reclaimed by generational GC, so megabytes of dead request
   data lingered until a rare gen-2 pass, and the transient copies
   fragment the allocator into a permanent RSS high-water mark. The
   handler now drops litellm_logging_obj from its stored kwargs; the
   caching layer never reads it.

3. The router stored every request's kwargs in the ITPM/OTPM contextvar
   even when no deployment configures itpm/otpm. Pooled resources
   created mid-request (e.g. redis connections) capture the asyncio
   context, extending that pin far past the request. The slot is now
   populated only for deployments with io token limits and overwritten
   with None otherwise.

Live-proxy verification (bursts of 30 x ~300KB requests, PII guardrail
+ prometheus + redis cache): unfixed grows 16-29MB per burst without
release; fixed grows under 1MB per burst after warmup and flattens.

feat(guardrails): add Compresr guardrail for query-aware context compression (#33295)
* feat(guardrails): add Compresr guardrail for query-aware context compression

Adds a first-class guardrail that compresses bulky message content (tool
outputs, RAG chunks, search results) through the Compresr API before the
request reaches the LLM, via the apply_guardrail / structured_messages hook
so it covers /chat/completions, /v1/messages, and /v1/responses (the latter
through the texts channel, mirrored only when the replacement is
unambiguous; anything ambiguous is left uncompressed).

Distinct from whole-conversation compressors:
- Query-aware: each message is compressed against the intent that produced
  it (a tool output against its originating tool call's name + arguments,
  resolved via tool_call_id; otherwise the last user message).
- Recoverable: each compressed message carries a hash marker and the request
  gains a compresr_retrieve tool, so the model can pull the original content
  back through the agentic loop when the compressed version is not enough.
  Originals are cached in-process, scoped to the caller's virtual-key hash
  plus the request's litellm_call_id, with a TTL and a per-call byte cap;
  recovery is skipped when no caller scope is available so one caller can
  never read another's originals. The store is per-process, so multi-worker
  deployments need sticky routing (or enable_retrieval=false).

Fail-closed by default (fail_open configurable), SSRF-validated api_base
(alternate IP-literal encodings included), cross-tenant-isolated recovery
store, and upstream errors redacted from client-facing responses. The
outbound client follows redirects and re-resolves DNS per request, so the
api_base host/IP checks are defense-in-depth, not a full SSRF guarantee;
this is documented as a known limitation. Requests where nothing was
actually compressed are returned untouched (same object identity) so
handlers skip the write-back. Auto-discovered via the guardrail_hooks
registry.

* fix(guardrails): cap Compresr recovery store total memory

The recovery store bounded bytes per call and entry count, but had no
aggregate cap: 256 tracked call ids at the 10 MiB per-call default could
retain ~2.5 GiB per worker. A flood of requests with distinct
x-litellm-call-id values and large compressible tool outputs could
exhaust a shared proxy worker.

Add a global byte budget (_MAX_TOTAL_STORE_BYTES, 256 MiB) across all
entries. A running total is maintained on every insert/eviction so the
cap is enforced without re-encoding the whole store on the request path;
oldest entries are evicted once the budget is exceeded, always keeping
the most-recent entry so recovery still works for the request populating
the store. +2 regression tests.

* fix(guardrails): gate and bound Compresr recovery loop

Two hardening fixes to the compresr_retrieve agentic loop:

1. Only run the loop when a retrieve call resolves to recovery state this
   guardrail actually created for the request. Previously the gate checked
   only that the caller-supplied tool list contained a compresr_retrieve
   function and that the model emitted a call, so a caller could define
   their own same-named tool and force an extra provider round-trip with
   nothing to recover. The plan now returns run_agentic_loop=False when no
   requested hash resolves.

2. Bound the follow-up against retrieval amplification: each distinct hash
   is expanded at most once (repeats get a short marker) and at most
   _MAX_RETRIEVALS_PER_LOOP calls are honored, so prompting the model to
   call compresr_retrieve many times with the same marker cannot balloon
   the follow-up. _retrieve_original now returns None on miss.

+3 regression tests; two existing security tests updated to assert the
stronger veto behavior (forged/cross-tenant hashes now stop the loop
entirely instead of returning a not-found follow-up).

* fix(guardrails): warn when Compresr recovery is skipped without auth scope

When enable_retrieval is on (the default) but the proxy has no per-key
auth, the request has no caller scope, so recovery is silently disabled:
content is compressed but the compresr_retrieve tool is never injected and
the originals are dropped, with no runtime indication. Emit a one-shot
call-time warning so operators can see recovery is being suppressed and
configure virtual-key auth. +1 regression test.

* style(guardrails): tighten Compresr guardrail comments

Condense the verbose multi-line inline comments and the api_base docstring
to concise form. No behavior change.

* fix(guardrails): keep injected tool on Responses API + bound recovery markers by byte cap

Two fixes for reviewer-flagged defects in the Compresr guardrail:

- Responses API: _merge_tools_after_guardrail iterated only over the
  request's original tools, dropping any tool a guardrail appended (the
  compresr_retrieve recovery tool) whenever the request already had tools.
  Keep the appended tools so recovery works on /v1/responses.

- Recovery markers: markers + originals were built for every compressed
  target before the per-call byte cap trimmed the store, so an evicted
  original left a marker the model could never retrieve. Attach recovery
  only while the store (existing entries under the same key + this call's
  originals) stays within the cap, so a shipped marker is always retrievable
  -- including on a later turn that reuses the store key.

Adds regression tests for both paths.

* refactor(guardrails): extract _existing_originals to keep apply_guardrail under the complexity gate

The byte-cap fix added a branch to apply_guardrail, tipping it past the
C901 complexity ceiling. Move the store lookup into a small helper; no
behavior change.

* fix(guardrails): harden Compresr SSRF blocklist, re-arm no-scope warning, tolerate odd tool shapes

* fix(guardrails): rerun input guardrails on Compresr retrieval follow-up

* chore: remove unrelated deepkeep files committed by mistake

feat(proxy): push-based OTLP billable-request metering for enterprise deployments (#31592)
* feat(proxy): push-based OTLP billable-request metering for enterprise deployments

Adds opt-in, license-gated metering that counts 2xx HTTP requests to LLM
inference, MCP, and A2A endpoints and exports them over mutual TLS to a global
OpenTelemetry Collector for request-based billing.

A pure ASGI middleware (BillableRequestMetricsMiddleware) classifies each
request by route and records one count per 2xx response via an injected
recorder. The recorder (BillingMetricsRecorder) owns a dedicated OTEL meter
provider and an OTLP/gRPC exporter authenticated with client certificates, kept
isolated from the global meter provider so a customer's own OTEL metrics are
untouched. The recorder is built only when a valid LITELLM_LICENSE is present
and the cert material is configured; otherwise the middleware is a transparent
pass-through.

Deployment identity rides on the mTLS client certificate rather than the
payload, so the secret license key is never sent as an attribute or header; only
the license org id travels as a resource attribute for cross-checking.

Resolves LIT-4089

* fix(proxy): align billable-request metering with the global collector

- switch the exporter to OTLP/HTTP with a TLS client certificate. The
  collector front end terminates mutual TLS and validates the client cert
  against our CA; server verification uses the system trust store, so the
  CA env var is now an optional override for private collectors
- resolve the metrics recorder on the first request via a factory instead
  of at import time, so deployments that provide the license and cert env
  vars through the YAML config's environment_variables export correctly
- close the metering bypass: classify /images/edits, /images/variations,
  /v1/messages, /v1/videos, video remix, /v1/ocr and Gemini generateContent
  as billable, and gate LLM routes to POST so GET reads (list videos, fetch
  a response) do not bill. Verified live: the collector count matches the
  UI usage page successful_requests exactly, with failures excluded on both
  sides

* fix(proxy): wrap enterprise billing import in try-except per code-quality gate

The check_unsafe_enterprise_import gate requires every import from an
enterprise-pathed module to be guarded. Annotate the factory with the
middleware's BillingRecorder protocol so no enterprise type import is
needed at type-check time

* chore: satisfy strict lint gates in billing modules

- builtin generics per UP006 (dict/tuple instead of typing.Dict/Tuple)
- noqa the deliberate blind catch that keeps metering from breaking startup
- sort proxy_server import blocks split by the guarded enterprise import

* fix(proxy): bill provider passthrough, search, and rag routes

Route-inventory audit against LiteLLMRoutes.llm_api_routes found more
SpendLogs-producing surfaces the classifier missed: provider passthrough
(/bedrock, /vertex-ai, /cohere and the rest of mapped_pass_through_routes),
/v1/search and vector-store search, and the rag ingest/query routes. All are
counted by the dashboard usage page, so missing them undercounts billing.

The passthrough prefix list is read from LiteLLMRoutes so new providers are
picked up without touching this module. /langfuse is excluded: it forwards
observability traffic and writes no SpendLogs row. Known limitation recorded
in the PR: /v1/realtime is a websocket flow the HTTP middleware does not see

* fix(proxy): bill MCP and A2A requests by protocol transport routes only

The billable-request classifier matched the whole /v1/mcp prefix, so
management and discovery reads such as GET /v1/mcp/tools and GET
/v1/mcp/server counted as billable MCP requests, while real MCP tool
calls on the /{server}/mcp and /toolset/{name}/mcp aliases were missed
because their route handlers rewrite the ASGI scope only after this
middleware has already classified the original path. Classify MCP by the
concrete transport surface (the /mcp streamable-HTTP and SSE sub-app plus
the single-segment server and toolset aliases) and exclude the /v1/mcp
management API. Apply the same shape to A2A, which had the identical
issue: only the /message/send invoke route bills, not /v1/a2a/discover or
the .well-known agent-card reads.

* fix(proxy): harden billable-request classification and recorder lifecycle

Exact-match Anthropic /v1/messages so OpenAI Assistants thread-message
routes no longer bill, add Google Interactions create routes, guard
recorder.record() so a broken exporter can never fail a served request,
lock lazy recorder resolution against concurrent first requests, and
disable metering on empty-string env config instead of accepting a
blank endpoint

* chore(ui): regenerate eslint metrics after staging merge

* docs(proxy): state the lower-bound billing contract in middleware comments

* fix(proxy): bill mcp-rest tool calls and bare a2a agent invokes

POST /mcp-rest/tools/call executes a tool and fires the same MCP spend
logging as the /mcp transport, and POST /a2a/{agent_id} is the JSON-RPC
invoke route whose method (message/send or message/stream) travels in
the body; both returned 2xx without being recorded

* fix(proxy): flush billable-request counts on proxy shutdown

PeriodicExportingMetricReader buffers up to one export interval of
counts; without a final flush every restart silently dropped them. The
factory registers the recorder it builds and proxy_shutdown_event pops
and flushes it, bounded by a 5s timeout so a dead collector cannot
stall shutdown

* fix(proxy): stop billing bare a2a task RPCs and close the shutdown race

POST /a2a/{agent_id} multiplexes JSON-RPC methods off the request body. Only
message/send and message/stream write a SpendLogs row; tasks/get, tasks/cancel
and the pushNotificationConfig RPCs are forwarded upstream and write none.
Classifying the bare path as billable counted those task RPCs and pushed the
metric above the dashboard's successful-request count. Since a path-only
classifier cannot read the body, the bare route no longer bills; the explicit
/message/send routes still do. Missing a bare-path invoke undercounts, which is
the only direction this metric is allowed to drift. The /mcp transport keeps
billing every method because its list path logs a SpendLogs row too.

The billing middleware also sat outside InFlightRequestsMiddleware, and it
records after the inner app returns. A request could therefore be counted as
drained while its record() had not yet run, letting proxy_shutdown_event flush
and stop the exporter underneath it. Registering it before the in-flight
tracker nests it inside, so wait_for_drain covers the record

* test(proxy): stub the OTLP exporter in the recorder-build test

test_premium_with_full_config_builds_recorder built a real MeterProvider, so
the shutdown flush resolved collector.example and opened a TLS connection from
a unit test. The exporter is now stubbed, and a getaddrinfo spy asserts nothing
resolves the collector host so the stub cannot be quietly dropped later

* fix(helm): truncate the helm.sh/chart label to 63 bytes

Kubernetes caps a label value at 63 bytes and .Chart.Version is unbounded. CI
publishes branch builds as 0.0.0-branch-<branch>-<sha>, so helm.sh/chart
rendered as a 64 byte value and the API server rejected every labeled resource
with "must be no more than 63 bytes", including the migrations Job. The
litellm-helm chart already guards this through a litellm.chart helper; this
adds the same helper here.

Swept the rest of the chart for label and name values built from unbounded
input. .Chart.Version appeared only in this label. The remaining candidates all
derive from .Release.Name, which helm itself caps at 53 characters, so they
cannot overflow; three of them are selector labels feeding immutable Deployment
matchLabels, where adding trunc would risk churn for no gain. They are left
alone deliberately.

Verified with a new helm-unittest suite, tests/chart_label_tests.yaml, which
overrides chart.version per test:

  helm unittest -f 'tests/*.yaml' helm/litellm      # 13 passed
  helm unittest -f 'tests/*.yaml' helm/litellm-helm # 54 passed

The truncation cases fail against the previous helper. Reproduced the original
overflow by rendering with the real branch version and measuring the label:

  helm template rel helm/litellm -f helm/litellm/tests/values/required.yaml \
    | grep helm.sh/chart   # 64 bytes before, 63 after

* feat(proxy): accept inline PEM for the billing-metrics mTLS credentials

LITELLM_BILLING_METRICS_CLIENT_CERT, _CLIENT_KEY and _CA_CERT took a filesystem
path. ECS injects Secrets Manager values as environment content and cannot mount
them as files, so a licensed deployment there could not turn metering on.

Each variable now takes either a path or the PEM itself. Inline PEM, detected by
the "-----BEGIN" prefix, is written once when the recorder is built into a 0700
temp dir as a 0600 file, and the config points at that path. The OTLP exporter
still only ever sees paths. A write failure disables metering through the
existing failure-as-None path rather than raising, and path-valued variables are
passed through untouched, so nothing changes for deployments that mount files.

The mixed case works too: mount the CA, inject the client credentials

* feat(helm): add first-class billingMetrics values to the componentized chart

Turning enterprise billable-request metering on meant hand-rolling the env vars
and the cert volume through gateway.extraEnv and gateway.volumes. This adds a
top-level billingMetrics block, off by default, consumed only by the gateway
since that is the component serving billable traffic.

When enabled it renders LITELLM_BILLING_METRICS_ENDPOINT plus the two cert paths
and mounts secretName read-only at /etc/litellm/billing-mtls. caSecretName is
optional and only needed for private collectors whose server certificate is not
on the public web PKI; when set it mounts at /etc/litellm/billing-mtls-ca and
adds the CA env var. exportIntervalMs is passed through only when set.

Enabling without secretName or with an empty endpoint fails the render with a
named message rather than producing a gateway that silently never exports.

The generic gateway.volumes, gateway.volumeMounts and gateway.extraEnv paths are
untouched and still compose with this, so existing overlays keep working.

The chart has no values.schema.json and no README, so there is nothing further to
update. Verified with a new helm-unittest suite:

  helm unittest -f 'tests/*.yaml' helm/litellm      # 23 passed
  helm unittest -f 'tests/*.yaml' helm/litellm-helm # 54 passed

* feat(terraform): billing-metrics variables for the aws and gcp templates

* feat(helm): add billingMetrics values to the classic chart

The componentized chart just gained a first-class billingMetrics block; this
mirrors it in litellm-helm so enabling enterprise billable-request metering no
longer means hand-rolling the env vars and the cert volume through envVars and
volumes.

When enabled the proxy Deployment renders LITELLM_BILLING_METRICS_ENDPOINT plus
the two cert paths, and mounts secretName read-only at /etc/litellm/billing-mtls.
secretName defaults to litellm-billing-metrics-mtls, the conventional name, so
enabling the block is enough once that Secret exists. caSecretName is optional
and only needed for private collectors whose server certificate is not on the
public web PKI; when set it mounts at /etc/litellm/billing-mtls-ca and adds the
CA env var. exportIntervalMs is passed through only when set.

The env entries render after envVars and extraEnvVars, so a user-supplied
LITELLM_BILLING_METRICS_ENDPOINT cannot silently redirect the export under
Kubernetes last-wins duplicate-env semantics; this is the same ordering the
migrations Job relies on for DISABLE_SCHEMA_UPDATE.

Enabling with an emptied secretName or endpoint fails the render with a named
message rather than producing a proxy that silently never exports.

The generic volumes, volumeMounts, envVars and extraEnvVars paths are untouched
and still compose with this, so existing overlays keep working. The chart has no
values.schema.json; README parameters and a setup section are updated.

  helm unittest -f 'tests/*.yaml' helm/litellm-helm  # 68 passed (54 + 14 new)
  helm lint helm/litellm-helm                        # 0 failed

* test(helm): pin that the migrations job never mounts the billing cert

The componentized chart's suite asserts the backend Deployment stays clear of the
billing wiring, since only the gateway serves billable traffic. The classic chart
has no backend, but it does have a second pod: the migrations Job, which renders
its own env from envVars and extraEnvVars. Nothing today wires the billing
include into it, and nothing stopped a future edit from doing so.

Asserts absence of the env, and that the Job grows no volumes or volumeMounts at
all. Both are notExists rather than notContains because the Job renders neither
key by default, so a notContains would fail on an unknown path instead of
checking the absence it looks like it is checking.

* fix(helm): meter the backend too, it serves the MCP transport

Scoping billingMetrics to the gateway was wrong. Applying each component's own
route allowlist to the proxy app shows the split is 75 billable routes on the
gateway and one on the backend: /{mcp_server_name}/mcp, the named-server MCP
transport, which writes a SpendLogs row on success. Metering only the gateway
would have silently dropped every MCP transport call from the counter, an
undercount proportional to a customer's MCP traffic.

The backend deployment now renders the same env and mounts the same read-only
cert secret. The migrations job still gets neither; it runs prisma and serves no
traffic, and a test pins that.

  helm unittest -f 'tests/*.yaml' helm/litellm      # 25 passed
  helm unittest -f 'tests/*.yaml' helm/litellm-helm # 69 passed

This also aligns the chart with the terraform templates, which inject the
credentials into both components.

* fix(proxy): never log billing credential values when they fail to resolve

Accepting inline PEM turned the cert env vars into secret-bearing values, but
the disable warning still echoed them. A value that is neither a readable path
nor `-----BEGIN`-prefixed PEM, for example a key with a preamble or a malformed
secret, fell through to the path branch and was written to the proxy logs
verbatim, exposing the client certificate or private key to anyone who can read
them.

The warning now names the offending environment variables and tells the operator
what a valid value looks like, without ever printing one

* Revert "fix(helm): truncate the helm.sh/chart label to 63 bytes"

This reverts commit 4f7f706a63.

Version hygiene belongs to the pipeline that mints chart versions, not to the
chart. The build workflow now caps the version slug so litellm-<version> fits
the 63 byte label budget, which removes the overflow at the source rather than
silently truncating a value operators use to identify the build.

Drops the litellm.chart helper, restores the direct helm.sh/chart printf, and
removes tests/chart_label_tests.yaml. Both chart suites stay green:

  helm unittest -f 'tests/*.yaml' helm/litellm      # 20 passed
  helm unittest -f 'tests/*.yaml' helm/litellm-helm # 69 passed

* feat(helm): default billingMetrics.secretName to the conventional name

The componentized chart required an explicit secretName while the classic chart
defaults to litellm-billing-metrics-mtls. Both now default to it, so the common
path is to create that Secret with tls.crt and tls.key and set enabled: true.

The required() guard stays, and with a default it now only fires when someone
explicitly blanks the override, which the tests pin from both sides

* feat(proxy): log once when billing metrics are actually enabled

build_billing_metrics_recorder returned None silently when the deployment was
not licensed, while every other disable path logged a warning. An operator
reading logs could not tell "metering active" from "metering off because this
component never saw the license", and a component can carry the cert mount and
the billing env and still meter nothing. That is the undercount direction the
metric is not allowed to drift in.

A successful build now emits one info line naming the collector endpoint and the
export interval; neither the certificate contents nor the license appear. The
unlicensed path logs at debug rather than warning, because unlicensed is the
common case and a warning there would be noise on every OSS proxy

* fix(terraform): fail the plan on a partial billing-metrics config

Each PEM secret is created only when its own variable is non-empty, so setting
billing_metrics_endpoint with a certificate but no key applied cleanly and left
the proxy logging "missing config" and never exporting. Silent non-export is the
undercount direction this metric must not drift in, and every other surface
fails fast on a half-configured metering block.

Both templates now carry a lifecycle precondition requiring the client
certificate and its key together whenever the endpoint is set. It lives on the
gateway task definition (aws) and the gateway Cloud Run service (gcp) rather
than on the secret resources, because those are themselves count-gated on the
PEM being present and would never evaluate in the failing case. Cross-variable
`validation` blocks would need terraform 1.9; versions.tf pins >= 1.6, and
preconditions work there.

ca_cert_pem stays optional, so an empty value still falls back to the system
trust store.

  endpoint  cert  key           result
  ""        any   any           metering off, no secrets created
  set       set   set           metering on
  set       missing either      plan fails

Verified each row with `terraform console` against the condition, and reran
`terraform fmt -check` and `terraform validate` in both directories

* docs(terraform): record why the billing guard sits on the gateway resource

The precondition cannot live on the cert secret, which is count-gated on
the cert itself and so has zero instances in exactly the case the guard
must catch. That makes the guard's correctness depend on this resource
staying unconditional, which nothing else records and no test enforces

* fix(terraform): guard the backend against a partial billing config too

The precondition only sat on the gateway, but the backend receives the billing
endpoint as well, because it serves the named-server MCP transport and meters
it. A targeted apply of just the backend task or service would therefore skip
the guard entirely and provision a component holding a billing endpoint with no
credentials to use it, which is the silent never-export failure the guard exists
to prevent.

Both templates now carry the same precondition on the backend resource. The
condition and truth table are unchanged; ca_cert_pem stays optional.

  terraform fmt -check and terraform validate clean in both directories

feedab214e fix(mcp): normalize blank OAuth endpoint fields to None at build entry points
A whitespace-only authorization_url was truthy to the row/config merges and
has_all check but blank to the corroboration gate, so discovery and
carry-forward adopted token_url/registration_url/scopes as if unpinned while
the broken whitespace value was still used for redirects. Rather than add
another strip() at each site, the pinned authorization_url/token_url/
registration_url are normalized once per build path (DB and config) via
_blank_to_none, so the merge, has_all gate, discovery gate, persist hook, and
carry-forward all see a single notion of blank. Empty and whitespace pins now
behave identically to an omitted field.

8650f6c7d3 fix(mcp): bound pinned-config discovery to the corroborated authorization server, scopes included
Provenance is a property of the whole discovered metadata document, not per
field. Waving scopes through while gating endpoints left a second inflation
vector: a compromised upstream advertises broad scopes via the resource
metadata (RFC 9728 / WWW-Authenticate), the gateway requests them from the
trusted authorization server, and the resulting token flows back to the
upstream. Both that and the token-endpoint mix-up are now one rule: when
authorization_url is admin-pinned, discovered token_url/registration_url are
kept only if the document corroborates the pin, and scopes come from the
authorization server's own scopes_supported (a new authorization_server_scopes
field, trusted tier) rather than the resource-advertised scopes. A document
that does not corroborate backfills nothing. Blank (empty-string)
authorization_url is treated as unpinned so the merge and the gate agree.
Carry-forward, the other non-manual source, drops the same three across an
authorization_url change.

447d50fa40 fix(mcp): enforce the OAuth endpoint trust rule at carry-forward too, elide default port
The corroboration check belongs to adopting a token_url from any non-manual
source, not to discovery alone. Carry-forward is the other such source: it
copied a prior registry entry's token_url/registration_url onto a rebuild
whose authorization_url had been re-pointed to a different server, reviving an
uncorroborated token endpoint the discovery gate would reject. Both sites now
share one predicate, _endpoints_corroborate_authorization_url: previous
endpoints carry forward only when the previous authorization_url corroborates
the authorize endpoint the build will use (absent -> the previous one is
adopted too, a consistent group; else it must match). Endpoint comparison now
elides the default port so :443 and formatting-only differences still match.

a81c6ce350 fix(mcp): reject discovered token endpoints uncorroborated by the manual authorization_url
Discovery is rooted at the MCP resource, so a compromised upstream can
advertise an attacker-run authorization server. When authorization_url is
manually configured and another field is blank, the per-field merge would
combine the trusted authorize endpoint with the advertised token_url, and
the gateway would redeem authorization codes (with the stored client secret
and PKCE verifier) at that endpoint, then persist it. Discovered token_url
and registration_url are now accepted only when the same metadata document
advertises an authorization_endpoint matching the configured value
(scheme+host+path). Scope backfill is unaffected. Applies to both the DB
and config build paths.

feat(router): resolve auto-router routing plugins from proxy YAML config (#33251)
* feat(router): resolve auto-router routing plugins from proxy YAML config

Router(plugins=[...]) was Python-SDK constructor only, so proxy/YAML users
had no way to configure it, and the merged pipeline narrowed candidates
from the outer model alias rather than the auto-router's actual tier pool,
making it a no-op for auto_router deployments.

Add complexity_router_config.plugins (dotted-path strings resolved via
get_instance_fn, the same convention litellm_settings.callbacks uses) and
run the resolved plugins against ComplexityRouter's tier pool at every
model-pick site, so a policy plugin narrows what get_model_for_tier
actually returns instead of the outer alias list. adaptive=True with
plugins set now raises at config validation instead of silently ignoring
the plugins, since the bandit selector doesn't consume narrowed pools yet.

Also fixes a latent bug in Router._generate_model_id: it json.dumps every
litellm_params dict value to build a deployment hash id, which crashed
once a live plugin object could land inside complexity_router_config.

* fix(router): use stable class name, not object repr, in model-id json fallback

json.dumps(v, default=str) on a litellm_params dict containing a live
RoutingPlugin instance fell back to object.__repr__'s default
<module.Class object at 0x...>, embedding the instance's memory address.
_generate_model_id's hash (and therefore the deployment id) changed on
every process restart/hot-reload for any deployment with
complexity_router_config.plugins configured, defeating the function's own
"consistently generate the same id" contract and orphaning anything keyed
on that id across restarts (e.g. Redis-backed per-deployment state).

Use the plugin's fully-qualified class name instead, which is stable
across restarts.

* test(router): cover _json_default_stable_id for router_code_coverage gate

router_code_coverage.py's AST scanner requires every router.py function be
called by name somewhere in tests/, and flagged the new
_json_default_stable_id helper from the previous commit.

* fix(router): close two routing-plugin policy-bypass gaps flagged by Veria AI

Session-affinity pin shortcut: async_pre_routing_hook returned a session's
first-turn pinned model on every later turn without ever re-running it
through the plugin pipeline, so a policy plugin (e.g. a budget cap crossed
mid-session) was only enforced on turn one. Now the pin shortcut is
disabled whenever plugins are configured, so every turn re-runs
_classify_and_route (and therefore the plugins).

Plugin resolution validation: get_instance_fn accepts any dotted path and
returns whatever object it finds there, so a misconfigured
complexity_router_config.plugins entry passed proxy startup silently and
only surfaced as a confusing AttributeError on the first request that
reached the plugin pipeline. Extracted the resolution logic into
resolve_complexity_router_plugins() and added an isinstance(...,
RoutingPlugin) check that fails proxy startup immediately with a clear
error instead.

* fix(router): raise instead of falling back to default_model on empty plugin-narrowed tier

default_model was never checked against the configured plugins, so it
functioned as an unconditional escape hatch around whatever policy a
plugin enforces -- a tenant/budget plugin narrowing a tier to zero
candidates could still be bypassed by the fallback. Drop the fallback
entirely for this path; a plugin narrowing to zero is a policy decision,
not something to route around, matching the fail-closed behavior the
Router-level plugin pipeline already uses for the same situation.

Flagged by Veria AI on PR #33251.

* style: ruff format complexity_router.py

* style(proxy): use modern str | None instead of Optional[str] in resolve_complexity_router_plugins

* fix(router): stop default_model short-circuit from skipping plugins on no-user-message path

self.config.default_model or await self._pick_model_for_tier(...) -- Python's
`or` short-circuits on a truthy default_model, so _pick_model_for_tier (and
therefore the plugin pipeline) never ran at all for the no-user-message path
whenever default_model was configured. A tenant/budget plugin's decision was
silently bypassable this way even after the other two policy-bypass fixes,
since this call site had a different shape from the other three pick sites.

Removed the short-circuit; falls through to _pick_model_for_tier ->
get_model_for_tier, which already checks the MEDIUM tier before default_model
-- the same priority every other call site uses.

Flagged by Veria AI on PR #33251.

* fix(router): address Greptile findings on the plugin-bypass fixes

Preserve default_model-first priority in the no-user-message path when no
plugins are configured, instead of unconditionally flipping to the MEDIUM
tier -- the plugin-bypass fix must not silently change model selection for
the (much larger) population of users who don't use plugins at all. Gated
on self.config.plugins, matching the pattern already used elsewhere in
this PR, per CLAUDE.md's guidance against backwards-compat flags when a
plain conditional does the job.

Also close a gap in the plugin validation added earlier:
@runtime_checkable only checks that `run` exists as an attribute, not that
it's a coroutine function, so a synchronous `def run(self, context)`
passed isinstance(resolved_plugin, RoutingPlugin) at startup and only
failed at request time with a confusing TypeError. Added an
inspect.iscoroutinefunction check.

Both flagged by Greptile on PR #33251.

2f15b5fb1d fix(mcp): cap per-user OAuth token cache TTL at the token's own lifetime
token_storage_ttl_seconds previously won outright over the token's expires_in, so a TTL longer than the token's lifetime kept the Redis fast path serving an expired bearer until eviction, while the stored refresh_token sat unused because refresh only runs on the DB read-through

The configured TTL is now capped at expires_in minus the expiry buffer. Shorter TTLs and servers without the field behave exactly as before, and the TTL still applies verbatim when the upstream reports no expires_in. The dashboard tooltips on the create and edit forms are updated to describe the capped behavior

109a1637a0 refactor(mcp): one traversal and one carrier choice-point for upstream listing failures
Both review findings shared one root cause: two exception-tree walkers with drifted semantics.
_extract_upstream_auth_failure walked the incidental __context__ chain before explicit causes, so a
403 raised while handling the causal 401 could shadow it; and the generic _get_tools_from_server arm
classified without extracting the challenge, so a nested 401 at client-build time surfaced without
the WWW-Authenticate the client needs. upstream_auth_challenge and raise_classified_list_failure in
faults/list_outcomes.py are now the single traversal and the single choice-point; both fetch arms
and _extract_upstream_auth_failure (also serving tool calls and the connect-time probe) delegate to
them, with dcr_bridge challenge suppression as a parameter so it holds on every path. The stale
_fetch_tools_with_timeout docstring describing the pre-change 403 absorb is rewritten to the actual
contract: 403 relays with its own status, an upstream-sent challenge relays verbatim per RFC 6750
insufficient_scope, and a challenge is only ever fabricated for a challenge-less 401

f776ea7f9b feat(mcp): per-server outcomes for aggregate tools/list and truthful single-server REST statuses
The aggregate MCP tools/list absorbed every per-server failure (upstream 401/403/5xx, timeouts,
network errors) into that server contributing zero tools, making a broken upstream indistinguishable
from a healthy server with no tools; the single-server REST list masked the same failures as
{"tools": [], "error": null, "message": "Successfully retrieved tools"}

Phase 2 of the MCP error-handling framework (LIT-4419): the manager fetch hops now raise a
classified MCPServerListError (faults/list_outcomes.py: total classifier, frozen outcome values)
instead of returning [], and each boundary applies the relay-vs-absorb policy matrix. The aggregate
keeps serving the healthy subset but records each server's outcome, surfaced on the tools/list
result _meta under litellm.ai/server_outcomes (the SDK passes a ListToolsResult through unwrapped)
and in spend logs as per_server_list_outcomes. Single-server REST requests relay truthful statuses
(unreachable/upstream_error 502, timeout 504, internal 500) and access denials now surface as real
403s instead of 200 unexpected_error bodies; upstream 403s surface through MCPUpstreamAuthError
like 401s. Outcome wire values carry category and status code only, never upstream prose

8ca809d426 fix(mcp): scope semantic filter matching and indexing errors to the requesting call
Match candidates are restricted to the request's own tool names via
route_filter, so routes learned from other principals' listings cannot
displace the caller's tools from top_k. Lazy indexing now uses the
async aadd flow exclusively; an embedding failure, including a
context-window overflow on an oversized description, raises for the
requesting call only and never writes the shared context_window_error,
so one request cannot poison the filter for every user on the worker.
The router is also sized to the configured top_k, which the
semantic-router index layer otherwise silently caps at its default
of 5.

feat(bedrock guardrails): add resource-less InvokeGuardrailChecks (detect-only) mode (#33299)
* feat(bedrock guardrails): add resource-less InvokeGuardrailChecks (detect-only) mode

Adopted from #30830 by OS-joaocastilho; the original PR was merged into
litellm_oss_staging_230626, which never landed, so this re-lands it on
litellm_internal_staging

Beyond the original diff, this fold includes the review fixups that were
made on the staging branch (warn on unrecognized check keys, keep empty
known checks as enable-with-defaults, fail fast when the checks block has
no usable keys, tz-aware datetimes, stricter typing) and adapts the block
path to the ModifyResponseException contract from LIT-4186, which replaced
GuardrailInterventionNormalStringError after the original PR was written

* fix(bedrock guardrails): only evaluate configured checks in violation collection

An unsolicited score in the InvokeGuardrailChecks response (e.g. a future
API revision returning checks the user never requested) previously fell
through to the default 0.5 threshold and could block a request the user
only asked to scan with other checks. Violation collection now skips any
check absent from the configured checks block

* fix(bedrock guardrails): fail closed on truncated PII results and tighten checks-path typing

Truncated sensitiveInformation results now count as a violation when the
PII check is configured: Bedrock omitted detections that were never
scored, so sub-threshold visible entries no longer let the request pass.
Also blocks on score == threshold per the documented contract (regression
test added), rejects checks combined with guardrailVersion, turns a
malformed 200 body into a logged guardrail_failed_to_respond 500 instead
of a raw ValidationError, types the checks parameter and violations
(BedrockChecksConfigModel, BedrockChecksViolation) instead of dict/object,
types _sign_and_post against AWSPreparedRequest, hoists stdlib imports,
and builds checks messages without intermediate mutation

* fix(bedrock guardrails): tag all InvokeGuardrailChecks INPUT content as user

Bedrock excludes system content from prompt-attack evaluation (per the
AWS guardrails docs), so mapping a caller-supplied system/developer
message onto the system role let a caller hide a prompt injection from
the promptAttack check by self-labeling its role. At the proxy every
INPUT message is caller-controlled, so all of it is now tagged as
untrusted user input, which also matches AWS guidance to tag untrusted
content as user input. OUTPUT stays assistant. Removes the now-unused
role map; the input-message test asserts the new tagging as a regression

* fix(bedrock guardrails): pass prepared request headers to httpx without dict coercion

httpx accepts botocore's HTTPHeaders mapping directly, and wrapping it in
dict() broke the existing test_bedrock_guardrail_make_api_request_passes_api_key
which supplies a bare Mock as the prepared request (dict(Mock) calls
Mock.keys())

chore(ci): sync litellm_internal_staging into daily OSS branch (#33337)
* feat(router): add LLM-based classifier option to complexity router (#32169)

* feat(router): add LLM-based classifier option to complexity router

Adds classifier_type: "heuristic" | "llm" to complexity_router_config.
When set to "llm", the router calls a configured model (e.g. a small
model like haiku) via structured output to pick the complexity tier,
falling back to the existing regex/keyword scorer on any error, empty
response, or unparseable output.

* feat(ui): add classifier_type option to complexity router UI, fix edit flow

Adds an "Advanced: Classification Method" section to ComplexityRouterConfig
with a heuristic/LLM toggle, revealing a classifier model picker and timeout
when LLM is selected.

Also fixes the auto router edit modal, which never rendered the complexity
router UI at all (it only handled the semantic router), and the "Edit Auto
Router" button visibility check, which was gated on auto_router_config and
never matched complexity router deployments.

* fix(router): attribute classifier calls to caller, raise default timeout

Forwards the original request's litellm_metadata into the classifier's
acompletion call. Without it, the proxy's cost-tracking gate sees no
user_api_key/team_id/user_id and silently drops spend logging and budget
accounting for every classifier call, letting an authenticated user rack
up unaccounted provider spend via repeated requests.

Also raises the default classifier timeout from 400ms to 3000ms (400ms
undershoots real LLM latency and would silently degrade to the heuristic
scorer on most requests) and corrects the module/class docstrings, which
still claimed zero external API calls after the llm classifier path was
added.

* fix(ci): resolve ruff strict-budget and frontend-lint failures

- Use PEP 585 generics (dict/tuple/list) in the new aclassify/_classify_with_llm
  signatures instead of typing.Dict/Tuple/List, and suppress BLE001 on the
  intentionally broad except in aclassify's fallback path with a reason.
- Fix prettier formatting in ComplexityRouterConfig.tsx.
- Regenerate eslint-metrics.json (was stale after the classifier UI changes).

* fix(ci): regenerate stale eslint-metrics.json

* fix(router): strip parent budget reservation from classifier metadata

The classifier's internal acompletion call previously forwarded the
parent request's full litellm_metadata, including its budget
reservation (user_api_key_budget_reservation / user_api_key_auth).
That reservation belongs to the routed completion the classifier is
deciding on, not to the classifier call itself, so it's now stripped
while key/team attribution fields are still forwarded for spend
logging.

completion_tokens_details.reasoning_tokens was None or absent. Also change
OutputTokensDetails.reasoning_tokens from int=0 to Optional[int]=None so that
re-instantiation without explicit reasoning_tokens no longer silently zeroes out
the field, and remove the same hardcoded zero from the mock_responses_api_response
initializer.

* test(responses): update assertions to match Optional[int] reasoning_tokens default

* fix(responses): preserve explicit reasoning_tokens=0 in usage translation

Align the reasoning_tokens guard with the is-not-None guards used for
text_tokens and image_tokens: a provider-reported zero passes through
while an absent value stays omitted.

  so callers see an exception instead of a benign stream chunk
- rate_limit* codes map to 429; client error codes (invalid_request_error,
  context_length_exceeded, etc.) map to 400; all other codes default to 500;
  raw integer codes are never used as-is as HTTP status codes
- ErrorEventError.param widened from Optional[str] to Optional[Union[str, Dict]]
  to prevent Pydantic ValidationError on dict-typed param payloads silently
  dropping error events before any type inspection

* test(responses-api): set completion_start_time on mock logging objects for internal staging _process_chunk

* fix(responses-api): map insufficient_quota to 429, derive failed-response log status from error code, and record failed-stream usage for spend accounting

insufficient_quota moves out of the 400 bucket; OpenAI returns HTTP 429 for it and the non-streaming exception mapping treats 429 as RateLimitError, so the in-stream mapping now agrees

_handle_logging_failed_response previously hardcoded APIError(status_code=500), so a rate-limited response.failed was logged to integrations as 500 while the caller saw 429; it now shares the same error-code-to-status mapping via _error_event_fields and _status_code_for_error_code

usage carried on a response.failed event is now stashed as combined_usage_object with its computed cost on the logging object before failure handlers run, reusing the mid-stream-interruption spend recovery path (_failure_handler_helper_fn, proxy post_call_failure_hook, _ProxyDBLogger), so failed streams count their billed tokens instead of logging zero cost

dedupe: TestMaybeRaiseForErrorEvent in tests/llm_responses_api_testing duplicated tests/test_litellm/responses/test_streaming_iterator_error_events.py, which is the canonical mirrored location and CI-covered via test-unit-responses-caching-types; the duplicate class is removed

* fix(responses-api): wrap retriable in-stream errors in MidStreamFallbackError and map error type field to status

Mirror chat streaming semantics from _handle_stream_fallback_error: 429 and
5xx in-stream error events now raise MidStreamFallbackError carrying the
mapped APIError so the router's FallbackResponsesStreamWrapper triggers
mid-stream fallback and cooldown; non-retriable 4xx still raise APIError
directly. Status mapping now reads both the OpenAI error type and code
fields, so type-classified client errors (e.g. invalid_request_error with
code invalid_prompt) map to 400 instead of falling through to 500.

* fix(responses-api): accumulate streamed output text so mid-stream fallback continues instead of restarting

MidStreamFallbackError was always raised with generated_content="", so the
router's stream_with_fallbacks treated every mid-stream error as pre-first-chunk
and retried with the original input, streaming duplicated content to clients
that had already received partial output. The iterators now accumulate
response.output_text.delta text (mirroring chat's response_uptil_now) and pass
it as generated_content, letting the router build a continuation input via
_build_responses_continuation_input.

* test(responses-api): pin in-stream token limit error to raised APIError

* fix(anthropic): strip @version suffix in _model_map_lookup_candidates (#32833)

vertex_ai/claude-opus-4-8@default (and sibling @default models) were
misclassified as non-adaptive because _model_map_lookup_candidates only
stripped provider prefixes but never the @<suffix> portion. The lookup
produced candidates like ["vertex_ai/claude-opus-4-8@default",
"claude-opus-4-8@default"], neither of which exists in model_cost, so
_is_adaptive_thinking_model returned False. LiteLLM then sent
thinking.type=enabled to a @default Vertex AI endpoint that requires
thinking.type=adaptive, resulting in a 400.

_strip_version_suffix now removes @<suffix> from each candidate,
adding the bare model name (e.g. "claude-opus-4-8") to the lookup
chain. Also adds supports_adaptive_thinking: true to the three
@default model_cost entries that were missing it as belt-and-suspenders.

* fix(datadog): split log batches proactively under intake payload limits

* fix(datadog): size intake chunks with exact wire serialization

* fix(anthropic): translate adaptive thinking/effort to pre-4.6 model support (#32867)

* fix(anthropic): translate adaptive thinking/effort to pre-4.6 model support

AnthropicMessagesConfig now reshapes the 4.6+ adaptive-thinking interface
(thinking:{type:adaptive} + output_config:{effort:...}) to whatever the routed
model supports. Thinking-capable non-adaptive models (e.g. Haiku 4.5, Sonnet 4.5)
get the effort translated to a legacy thinking budget_tokens. Models with no
reasoning support have thinking/effort dropped under drop_params. And because
adaptive thinking carries no budget while the legacy form must satisfy Anthropic's
max_tokens > budget_tokens rule, the translated budget is capped below max_tokens,
dropping thinking when max_tokens can't fit the minimum budget. 4.6+ models pass
through untouched.

This matters because clients like Claude Code speak native Anthropic /v1/messages
and send the adaptive interface unconditionally, regardless of the routed model.
The native passthrough previously only capability-gated the OpenAI-style
reasoning_effort alias and forwarded native output_config/adaptive thinking raw, so
a pre-4.6 model rejected it with "This model does not support the effort parameter"
and the request failed. Claude Code already gets drop_params auto-set, so its
requests now succeed.

* test(anthropic): gate undersized-max_tokens thinking drop on drop_params; add edge tests

Addresses review feedback on the max_tokens-too-small branch. Previously a
thinking-capable model whose max_tokens could not fit the minimum thinking budget
had thinking silently dropped regardless of drop_params, while a residual
output_config field in the same call still raised when drop_params was off. Gate
both consistently on drop_params: raise a clear error (naming max_tokens for the
undersized case) when drop_params is off, drop otherwise. Claude Code gets
drop_params auto-set, so it still succeeds.

Adds tests for the undersized-max_tokens raise, the residual output_config raise,
and the no-adaptive-interface passthrough on a non-adaptive model.

* fix(anthropic): make adaptive-effort translation silent to avoid breaking provider strip contracts

The previous raise-when-not-drop_params behavior broke existing bedrock and vertex
messages tests: those providers already silently strip unsupported output_config
for pre-4.6 models (issue #22797) with no drop_params required, and the shared
parent transform raising pre-empted that. It also conflicted with the goal of
keeping requests working rather than failing them.

Make the reshape silent: translate effort to legacy thinking for thinking-capable
models, drop thinking for non-reasoning models, and remove only the consumed effort
key from output_config, leaving any residual (e.g. format) for provider subclasses
(bedrock/vertex) to handle. No raise, no drop_params gating. This also resolves the
review note about inconsistent drop_params handling by making every path uniform.

Updates the tests to assert the silent behavior and residual output_config
preservation.

* fix(anthropic): handle output_config-capable but non-adaptive models (Opus 4.5)

Greptile caught a real bug: the early-return guard treated supports_output_config
as equivalent to supporting adaptive thinking. Claude Opus 4.5 advertises
supports_output_config (it accepts output_config.effort) but is not adaptive, so it
rejects thinking:{type:adaptive} with "adaptive thinking is not supported on this
model". The guard early-returned for Opus 4.5 and forwarded the adaptive thinking
block raw, reproducing the exact failure the fix is meant to prevent.

thinking:{type:adaptive} and output_config.effort are independent capabilities.
Only early-return for adaptive-thinking models. For a model that supports
output_config.effort but is not adaptive, keep the native effort and drop only the
unsupported adaptive thinking block. Verified live against Opus 4.5: the Claude Code
payload now returns 200 instead of 400.

Adds regression tests for Opus 4.5 with and without adaptive thinking.

* fix(anthropic): translate adaptive thinking for effort-capable pre-4.6 models

Claude Opus 4.5 advertises supports_output_config but not adaptive thinking,
so the early-return guard forwarded thinking.type=adaptive raw and Anthropic
rejected it. The guard now only skips true adaptive models; effort-only
requests on effort-capable models still pass through untouched. The
_map_reasoning_effort call is wrapped to surface unrecognized effort values
as a clean 400, matching _translate_reasoning_effort_to_anthropic

* fix(anthropic): fall back to legacy thinking when effort level unsupported

Opus 4.5 accepts output_config.effort but only low/medium/high; Claude Code
defaults to xhigh on newer models, so preserving that level raw gets rejected
by Anthropic. Gate the native-effort passthrough on _validate_effort_for_model
and fall through to the budget translation for unsupported levels

* fix(anthropic): keep effort-only requests untouched for provider normalization

The xhigh fall-through consumed effort-only requests on effort-capable
models, breaking bedrock invoke's own normalization which clamps xhigh to
the model's ceiling after the base transform runs
(test_bedrock_messages_normalizes_output_config_effort_for_opus). Restrict
the fall-through to requests that carry adaptive thinking; effort-only
requests pass through so provider subclasses keep owning level clamping

* test(models): assert capability fields on regional Azure gpt-5.6 entries (#32875)

* feat(auto_router): keyword tier overrides and semantic keyword matching for the complexity router

Add deterministic keyword-to-tier overrides and optional embedding-based
(semantic) keyword matching to the complexity router, and surface both in the
Add Auto Router UI behind a Router Type selector: "Auto-Router v2 [Recommended]"
(complexity tiers + keyword overrides + semantic matching, the default) and
"Semantic Router [to be deprecated]" (the existing utterance-based router,
unchanged). Keyword-to-tier overrides resolve to the highest tier matched
rather than the first keyword matched, so match order no longer affects the
routing decision.

Backend:
- config: KeywordTierRule model plus keyword_tier_rules, semantic_keyword_matching,
  embedding_model, and match_threshold on ComplexityRouterConfig, with a validator
  requiring an embedding model and rules when semantic matching is on
- complexity_router: evaluate keyword rules before scoring; lexical matches escalate
  to the most-severe matched tier (order-independent), and semantic mode reuses
  LiteLLMRouterEncoder + SemanticRouter to match paraphrases by cosine similarity,
  falling back to the scorer when nothing matches
- model management: clear complexity_routers on cache reload so config edits take effect

Frontend:
- Add Auto Router tab restores the Router Type radio (Auto-Router v2 recommended
  by default, Semantic Router still available) and sends keyword_tier_rules plus
  the semantic settings on the recommended path, instead of flattening keywords
  into custom_technical_keywords
- client-side guard blocks submit when semantic matching is enabled without an

* fix(bedrock): flag mapped Claude 4.8+ entries with supports_mid_conversation_system (#32882)

Exact cost-map hits resolve before fallback-generalization rules, so the
mapped Sonnet 5, Fable 5 and jp Opus 4.8 Bedrock entries bypassed the
bedrock-anthropic-claude-mid-conversation-system rule and hoisted
mid-conversation system messages, invalidating the prompt cache.

* feat(team): let org admins reach PATCH /team/{team_id} like POST /team/update

Wire the coarse route gate so PATCH /team/{team_id} is reachable by exactly the roles that can call POST /team/update: proxy admins, org admins of the team's own organization, and JWT admins. Regular internal users and view-only proxy admins stay blocked, matching the existing endpoint

Because the team id lives in the path rather than the body, the org-context resolver now also reads it from path_team_id for the bare /team/{team_id} route, so an org admin's organization is resolved and injected the same way it already is for POST /team/update. /team/{team_id} is added to management_routes rather than the role-agnostic self_managed_routes; the latter would have opened POST /team/new to any authenticated user through the shared /team/{team_id} path pattern

* feat(ui): root the gateway breadcrumb in the AI Gateway selector

The AI Gateway select (ViewSwitcher) now sits at the root of the DashboardHeader breadcrumb instead of on the right, so the top bar reads [AI Gateway select] > Page to match the redesign. It keeps the same dropdown, including the Chat / Chat UI options.

When no plugins are registered and Chat UI is disabled there is nothing to switch between, so the breadcrumb falls back to the static section crumb rather than rendering a dangling leading separator

* fix(complexity_router): build semantic route index once under concurrent cold-start

Concurrent first requests each hit asyncio.to_thread to build the SemanticRouter
index, firing duplicate embedding calls for the static route utterances. Guard the
lazy build with a per-router asyncio.Lock (double-checked) so the index is
constructed exactly once regardless of how many callers race in cold.

Adds a regression test asserting ten simultaneous cold-start requests build the
index the same number of times as a single request, and reworks the fake embedding
router to count builds by how often a route utterance is embedded (robust to which
embedding path the library uses) while still recording sync-call thread ids for the
off-event-loop assertion.

* feat(ui): always show the gateway selector with a discoverable Chat entry

The AI Gateway selector now always renders at the breadcrumb root, even with no plugins and Chat UI disabled, so the Chat feature stays discoverable. The Chat entry is always listed: clickable when enabled, and disabled with an "Admins can enable in Settings" hint when it is off.

Since the selector is now unconditional, the useViewSwitcherVisible hook and the section-crumb fallback added in the previous commit are removed

* fix(proxy): guard delete_model router eviction on auto_router/ prefix

delete_model popped the auto_routers/complexity_routers registries by the deleted
deployment's model_name without checking it was actually an auto_router/* deployment.
Deleting a regular DB model that merely shares a name with a config-defined router
therefore evicted that router, which add_deployment never restores, leaving it
unroutable until a proxy restart. This is the same cross-tenant DoS clear_cache was
hardened against; mirror its auto_router/ prefix guard here.

Extracts _deployment_name_and_model to read model_name and litellm_params.model from
the deployment (delete_deployment returns the raw model_list dict at runtime despite
its Deployment annotation), and adds a regression test asserting a same-named config
router survives deletion of an unrelated regular model.

* fix(team): bound json merge patch recursion depth

apply_json_merge_patch recurses into nested objects, which the repo's recursive_detector code-quality check flags because unbounded recursion over caller-supplied JSON has caused CPU/stack issues before. Cap the recursion at a depth far above any realistic team-metadata shape and reject deeper patches with a ValueError so a pathologically nested body fails closed instead of overflowing the stack, then register the function in the detector's ignore list alongside the other depth-bounded JSON walkers

* fix(auth): tolerate request objects without path_params in common_checks

The PATCH /team/{team_id} org-context wiring reads request.path_params to
resolve the team id from the path. A real Starlette Request always exposes
path_params, but common_checks is exercised with lightweight request doubles
that don't, which raised AttributeError. Read it defensively so a missing or
null path_params falls back to no path team id, matching the "not a bare team
route" outcome; real requests are unaffected

* fix(mcp): re-register DCR client when proxy origin no longer matches its registered redirect_uri

A dynamically registered (RFC 7591) OAuth client persisted onto the MCP server row is bound to the redirect_uri it was first registered with, but that binding was never recorded. After the proxy's public origin changed, every authorize paired the reused client with the new callback and the IdP rejected it permanently.

The DCR persist now records redirect_uris alongside the client identity. The admin register path treats a positive mismatch between the recording and the current callback as stale and re-registers a replacement client; rows without a recording (pre-existing installs and admin-configured clients) are grandfathered so upgrades never re-mint client_ids or orphan refresh tokens. The persist also writes client_secret and token_endpoint_auth_method explicitly as None when absent so the credential blob merge cannot pair a re-registered public client with the previous client's secret. Public register routes and non-admin callers keep existing behavior.

Closes #32473

* fix(mcp): emit one operator warning per DCR re-registration event

The stale-redirect path logged three warnings for a single re-registration: the staleness probe plus the reuse skip in both register_client_with_server and the persist race guard. The reuse-skip message is a mechanical consequence of the probe's decision, so it now logs at debug; the actionable warning that names both bindings and the re-authentication impact is emitted once by _persisted_dcr_redirect_uri_is_stale

* refactor(ui): use TanStack Pacer debounce for the team keys search

Replace lodash/debounce in TeamVirtualKeysTable with useDebouncedValue from
@tanstack/react-pacer, matching the sibling VirtualKeysTable and
PaginatedKeyAliasSelect which already debounce their key-alias search that way.
Pacer is already a dependency, so this drops the odd-one-out lodash usage and
keeps the search-debounce pattern consistent across the key tables.

* feat(ui): typed openapi-fetch foundation (fetchClient) + first typed caller (useCustomers) (#29884)

* feat(ui): add the typed openapi-fetch client (fetchClient) as the dashboard fetch foundation

Introduces fetchClient (openapi-fetch) bound to schema.d.ts, used inside ordinary TanStack Query hooks so path/query/body types come from the proxy's OpenAPI spec. A small runtime registry feeds the client the base URL and auth header name (registered by networking) and the session token (published by AuthContext), so call sites carry no token plumbing; auth-header injection and ApiError mapping live in openapi-fetch middleware reusing deriveErrorMessage/ApiError from client.ts, and non-2xx maps to a thrown ApiError so query functions just read .data.

The base URL default resolves from NEXT_PUBLIC_BASE_URL so a request still targets the right origin if it fires before networking registers its getter. AuthContext clears accessToken alongside the token on logout so no query fires unauthenticated after the session ends.

Foundation only; callers migrate one at a time, each fully typed, in follow-up changes.

* feat(ui): migrate useCustomers to the typed fetchClient

Converts useCustomers from allEndUsersCall to fetchClient.GET("/customer/list"); the response is typed as LiteLLM_EndUserTable[] from the schema, so the hand-written Customer/CustomersResponse types are deleted. They were also inaccurate (allowed_model_region was string but is "eu"|"us", and a budget_id the table has no field for). No cast; the schema type flows to the one consumer. First caller on the new pattern.

* fix(ui): route typed-client errors through the session-expiry handler

The typed fetchClient middleware threw ApiError without invoking the
handleError side effect that the legacy createApiClient wires via
onError, so a migrated caller hitting an expired key no longer triggered
the auto-logout. Add an error-handler seam to runtime.ts, register
handleError from networking.tsx alongside the base-url/header getters,
and call it in the middleware before throwing so both clients behave the
same. Regression test asserts the handler fires with the derived message
on non-2xx and stays silent on success

* fix(ui): point the customers EndUser type at CustomerResponse

The /customer/list response model was renamed to CustomerResponse on
staging; the merged branch still aliased EndUser to LiteLLM_EndUserTable,
so the exported type and its test mock had drifted from what the schema
actually returns. CustomerResponse is also the accurate shape (it types
allowed_model_region as 'eu' | 'us' and carries budget_id)

* chore(ui): refresh eslint-metrics baseline after staging merge

The recorded baseline predated the litellm_internal_staging merge, so its
no-explicit-any and no-large-inline-object-arg counts were higher than the
merged tree actually has. Regenerate via npm run lint:metrics so the gate
reflects current reality

* refactor(ui): source the typed client token from the session cookie, not AuthContext

The typed client read its bearer from a runtime value that AuthContext pushed
via setAuthToken, but migrated hooks gate enabled on useAuthorized, which
decodes the cookie directly. Two independent derivations of the same cookie with
different timing: on first load the query fires (useAuthorized sees the token)
before AuthContext's async effect publishes it, so the first request goes out
unauthenticated and only succeeds on a React Query retry.

Make the token a registered getter like the base-url and header-name getters,
reading the same cookie useAuthorized decodes, so the client's token and the
gate can't diverge. Revert the AuthContext changes entirely; nothing is pushed
from React state anymore.

* test(e2e): cover Langfuse logging.yaml P0 logs_spend cells (#32857)

* test(e2e): cover Langfuse logging.yaml P0 logs_spend cells

Team, user/key, and org-scoped dynamic Langfuse callbacks drive real chat
traffic and assert calculatedTotalCost matches StandardLogging response_cost
and proxy spend. Also assert tool calls and applied guardrails land on the
trace. Missing env or proxy is a hard failure, never a skip

* test(e2e): use langfuse_otel callback for Langfuse spend coverage

* fix(complexity_router): use max aggregation for semantic keyword route scoring

SemanticRouter defaults to mean aggregation across a route's utterances. Since
each tier's route holds one utterance per configured keyword, a real semantic
match on one keyword was averaged together with the tier's other, unrelated
keywords and dragged below match_threshold — e.g. a MEDIUM tier with keywords
[beep, boop, new york] never fired for a genuine "new york" paraphrase, because
mean(sim_to_beep, sim_to_boop, sim_to_new_york) landed well under the threshold
even though sim_to_new_york alone cleared it. Pass aggregation="max" so a tier
matches if the query is close enough to any one of its keywords, not the
average of all of them.

Verified against live Voyage embeddings: raw cosine similarity for "new york"
vs a paraphrase was 0.54 (above a 0.5 threshold), but the route scored 0.28
under mean aggregation and never matched; max aggregation fixes it.

Adds a regression test with a tier holding one matching and two unrelated
keywords, asserting the tier still fires; fails without aggregation="max".

* refactor(auth): resolve PATCH team org-context from the route template

Replace the request.path_params read (and its defensive getattr guard) with
the route template. A real Starlette request always exposes path_params, but
common_checks runs on lightweight request doubles that don't, so reading it
directly forced a getattr workaround that only existed to tolerate those
doubles.

Instead, match the route template (/team/{team_id}) to identify the RESTful
update route and take the team id from the last path segment. This drops the
path_params dependency entirely, and because the template distinguishes the
PATCH route from its single-segment siblings (/team/new, /team/list, ...), it
also avoids a spurious team lookup those routes would otherwise trigger if we
matched the resolved path shape alone.

* chore(ui): remove eslint-metrics.json lint-count snapshot

The eslint-metrics.json snapshot duplicated the violation counts already
enforced by eslint-budgets.json. Keeping it current added a CI drift check,
a pre-commit regenerate-and-flag step, and a standalone npm run lint:metrics
script, none of which caught anything the budget gate did not, yet all of
which failed noisily whenever the snapshot went stale. This drops the file
and that machinery while leaving eslint-budgets.json as the actual ratchet
gate

* fix(complexity_router): preserve user_api_key_auth in sub-call metadata

Removing user_api_key_auth entirely from classifier/embedding sub-call
metadata (as _BUDGET_RESERVATION_METADATA_KEYS previously did) prevented
_filter_deployments_by_model_access_groups from scoping those sub-calls to
the caller's authorized access groups. An access-group-scoped caller could
therefore reach embedding/classifier deployments outside their group.

Only strip user_api_key_budget_reservation, which is the actual budget-
reservation state that must not reach sub-calls. user_api_key_auth is now
kept so access-group filtering works correctly for both the embedding path
and the LLM classifier path.

* test(e2e): drop vertex from pipecat tool smoke (#32925)

Exclude vertex_ai from pipecat tool smoke; raw-ws tool_call_round_trip

* fix(complexity_router): sanitize budget reservation inside forwarded user_api_key_auth

* fix(complexity_router): review hardening - blank keywords, router registry eviction, edit-modal controls

- config: KeywordTierRule now strips and drops blank/whitespace keywords (a stray
  "" makes _keyword_matches match every prompt, silently forcing that tier for all
  traffic); still requires at least one real keyword to remain
- frontend build_complexity_router_config: trim keywords and drop rules left empty so
  an unfilled "Add keyword rule" row no longer ships a rule the backend rejects with a
  400 in the heuristic (non-semantic) flow, where the client-side semantic guard doesn't run
- proxy clear_cache / delete_model: the auto_router/ prefix also covers quality_router/
  and adaptive_router/, so pop the model_name from all four router registries (no-op
  where absent) instead of only auto/complexity; otherwise a DB quality_router's stale
  entry made reload raise "already exists" and abort, and adaptive left a leak
- frontend ComplexityRouterConfig: only render the Keyword Tier Overrides and Semantic
  keyword matching sections when their change handlers are provided, so the edit-auto-
  router modal (which omits them) no longer shows interactive-but-dead controls

* fix(anthropic): thread real provider through capability probes instead of pinning anthropic

* fix(anthropic): override custom_llm_provider in provider config subclasses so capability probes use the right namespace

* feat(mcp): admit dcr_bridge oauth_delegate clients via a single envelope bearer

* fix(mcp): admit dcr_bridge envelopes under the live key, not a frozen identity

The bridge envelope sealed only user_id/server_id, and admission fabricated a
UserAPIKeyAuth(user_id=...) with no object_permission, team_id, org_id, or key
identity. Downstream MCP permission checks read the missing restrictions as
unrestricted, so a caller holding a valid envelope for a restricted key could
reach tools and servers that key was never granted, and a revoked key kept
working until the envelope expired.

Bind the hashed authorizing key into the envelope identity and reload the live
UserAPIKeyAuth by it at admission via get_key_object, failing closed with a 401
when the key is missing, blocked, or expired. Authorization is resolved fresh
per request instead of frozen at mint time, so current key/team/org and tool
restrictions plus revocation are enforced.

* fix(mcp): enforce team block and alias-priority token injection on bridge admission

Two follow-ups on the envelope admission arm flagged in review.

Team revocation bypass: _reload_admitted_key checked only the key's own
blocked/expires, so blocking a key's team left every envelope minted under it
live until expiry. Reload the team and reject a blocked team, mirroring
common_checks, so a team block revokes its envelopes immediately.

Caller-overridable upstream token: egress resolves the per-server auth header
alias-first, but injection keyed under server_name, so for a server with a
distinct alias a caller-forwarded x-mcp-{alias}-authorization sat at the
higher-priority slot and paired the admitted identity with an attacker's
upstream credential. Inject under alias-first so the sealed token owns the slot
egress resolves.

* fix(mcp): route bridge admission through the centralized policy gate and mirror the SCIM owner check

* fix(mcp): import assert_never from typing_extensions for Python 3.10

* fix(mcp): surface real status from bridge admission policy gate instead of flattening to 401

Over-budget rendered 401 (should be 429), model-access and other typed
failures collapsed to 401, and a transient DB outage was masked as an auth
error. Mirror UserAPIKeyAuthExceptionHandler: budget maps to 429, a sub-check's
own HTTPException/ProxyException keeps its status, a DB outage is a retryable
503, and only a genuinely unresolvable failure stays the fail-closed 401.

* fix(rate-limit-v3): populate x-ratelimit-* remaining/limit values in standard_logging_object for streaming (LIT-4333) (#32711)

Streaming requests return from common_request_processing before
async_post_call_success_hook runs, so response._hidden_params.additional_headers
never gets the v3 x-ratelimit-{descriptor_key}-{remaining|limit}-{rate_limit_type}
entries. Prometheus / logging callbacks that read those values from
standard_logging_object.hidden_params.additional_headers then see nothing;
combined with the pre-existing gap that Prometheus reads from that same slot
(LIT-2577 / PR #28816), per-key remaining RPM/TPM cannot be monitored for
streaming traffic at all.

Fix in three parts:

- Stash the pre-call RateLimitResponse in the metadata channels the async
  success-logging callback inherits, alongside the existing top-level entry
  the non-streaming path reads.
- Add async_logging_hook to the v3 handler. It fires in a distinct earlier
  loop inside async_success_handler (all callbacks' async_logging_hook
  complete before any async_log_success_event starts), so mirroring the
  pre-call snapshot into standard_logging_object.hidden_params.additional_headers
  and response._hidden_params.additional_headers here guarantees every
  downstream success callback sees the values regardless of registration
  order. Non-streaming keeps the existing async_post_call_success_hook write
  and this hook re-populates the same values idempotently.
- Extract the shared `_merge_ratelimit_statuses_into_additional_headers`
  helper the non-streaming path already had inlined so both callsites emit
  the identical key shape.

* fix(proxy): skip None model_name in clear_cache router eviction set

* fix(mcp): map a DB outage during bridge key reload to a retryable 503

get_key_object's raw transport error propagated uncaught out of
_reload_admitted_key as an opaque 500; classify it via the shared
_raise_503_if_db_unavailable helper (also used by the live-policy gate) so a
database outage is a retryable 503, while a key-not-found ProxyException stays
the fail-closed 401.

* test: remove live OpenAI fine-tuning job-creation test blocked by platform wind-down (#32933)

OpenAI is winding down self-serve fine-tuning and the org can no longer
create fine-tuning jobs (403 training_not_available; the CI key surfaces
it as a 500 server_error), so test_create_fine_tune_jobs_async fails on
every batches_testing run since 2026-07-11 and reruns never clear it.
The request contract stays covered by the mocked create/list/cancel/
retrieve tests in the same file, and the deleted test's unique
standard_logging_object assertions now run inside
test_mock_openai_create_fine_tune_job.

* refactor(anthropic): consolidate the provider fallback into a _resolved_provider property

* feat: add lite auth print-token for Claude Code apiKeyHelper support (#32846)

* feat: add silent CLI token refresh for apiKeyHelper support

lite auth print-token prints a valid proxy credential for use as Claude
Code's apiKeyHelper, transparently refreshing it first if the cached JWT
is stale. This unblocks MDM-managed apiKeyHelper deployments (managed
via `lite auth print-token`) that need silent mid-session credential
rotation without restarting the client.

Refresh capability is backed by a virtual key minted with an empty model
list and cli_refresh metadata, kept strictly separate from the actual
(short-lived, real-model-scoped) call credential -- so a leak of the
credential that flows through every LLM request and subprocess env var
can't also self-renew. The refresh flow is single-use: /sso/cli/refresh
mints a fresh JWT + refresh token pair and blocks the presented refresh
token immediately, so a replay can't mint a second pair from it.

Server: /sso/cli/refresh (rotate) and /sso/cli/logout (revoke) endpoints.
lite login now also stores a refresh token; lite logout revokes it
server-side instead of only clearing the local file.

* fix: allow non-admin users to hit CLI refresh routes; resolve apiKeyHelper base_url from token.json

Found via a live end-to-end test against a real proxy + real Claude Code
session: /sso/cli/refresh and /sso/cli/logout were unreachable for any
non-proxy-admin caller, since Depends(user_api_key_auth) pulls in a
route-RBAC gate that 403s any route not on an explicit allowlist. That
made the feature unusable for actual end users, who authenticate as
internal_user. Add both routes to internal_user_routes; the handlers
already do their own fine-grained check (metadata.cli_refresh) same as
/key/block does today.

Also: `lite auth print-token` required an explicit --base-url/
LITELLM_PROXY_URL matching the stored token's origin, defaulting to
localhost:4000 otherwise. But apiKeyHelper is configured bare (no
flags), so this always mismatched a real deployment. Track whether
--base-url was explicitly passed (via click's ParameterSource) and, if
not, resolve the server from token.json directly instead of the CLI
default.

* test: mock refresh-token minting in test_cli_poll_key_tolerates_missing_user_row

Landed on litellm_internal_staging after this branch's refresh-key minting
change; needs the same mock as the other cli_poll_key tests since minting
now runs unconditionally whenever a JWT is generated.

* fix(ci): update test_cli_auth.py for refresh_token contract, regenerate schema.d.ts

_poll_for_authentication now always includes "refresh_token" in its
returned dict, and _handle_team_selection_during_polling returns a dict
instead of a bare JWT string -- test_cli_auth.py predates this branch's
refresh-token work and still asserted the old shapes.

schema.d.ts regenerated via `npm run gen:api` to pick up the new
/sso/cli/refresh and /sso/cli/logout routes (plus unrelated drift from
other PRs merged since it was last generated).

* fix(ci): apply CI's own schema.d.ts diff (enterprise routes I can't generate locally)

Local `npm run gen:api` only sees OSS routes -- this machine's
litellm_enterprise editable install points at a now-deleted temp
directory, so it silently drops enterprise-only routes from the spec.
Applied the exact diff CI's own generation produced instead of
re-running the generator locally.

* fix: close refresh-token race, fail closed on DB down, fix logout base_url

Addresses Greptile review findings on the CLI refresh-token PR:

- cli_refresh_token minted a new JWT + refresh token BEFORE blocking the
  presented one. Two concurrent requests bearing the same refresh token
  could both pass auth and both mint fresh pairs, yielding four live
  credentials from one consumed token. Now the presented token is
  consumed atomically first via update_many (only succeeding if it flips
  blocked from False/None to True); the loser gets count=0 and is
  rejected before anything is minted.
- When prisma_client is None, refresh silently returned a new JWT
  without ever being able to mark the presented token consumed, leaving
  it valid indefinitely. Now fails closed with a 500 instead.
- `lite logout` sent its revocation POST to ctx.obj["base_url"], which
  defaults to localhost:4000 when --base-url isn't passed -- the same
  bug print_token had before the base_url_explicit fix, just missed
  here. Now resolves the same way: trust the stored token's origin
  unless the caller explicitly overrode --base-url.

* fix(ci): satisfy ruff format and narrow token_data type in logout

* fix(security): never trust refresh-token metadata for authorization

Addresses a real privilege-escalation path Veria flagged: cli_refresh_token
read team_id, team_alias, and max_budget straight off the presented
token's own metadata and used them to authorize the new JWT. Since any
authenticated user can self-mint a virtual key with arbitrary metadata
via the ordinary /key/generate endpoint, a self-forged key with
{"cli_refresh": true, "team_id": "<any-team>", "max_budget": 999999999}
would sail through _require_cli_refresh_token's only check
(metadata.cli_refresh == True) and get a JWT scoped to a team the
caller never belonged to, with a budget it never had -- full
cross-team / budget bypass, and a removed team member could keep
refreshing team-scoped sessions indefinitely.

Metadata's team_id is now treated as an untrusted UX hint only: honored
solely if the CALLER (identified by the authenticated key's own
user_id, not client input) is a current member per a fresh
get_user_object lookup. team_alias and max_budget are never read back
from metadata at all -- team_alias comes from a live get_team_object
lookup and max_budget is recomputed with the exact same capping logic
the initial SSO login poll uses. _mint_cli_refresh_token no longer
accepts or stores team_alias/max_budget, only the team_id hint.

Added regression tests proving: a forged/stale team_id is dropped
(falls back to no team, not silently honored), and a forged max_budget
in metadata never reaches the issued JWT.

* fix(ci): catch HTTPException specifically instead of bare Exception (BLE001)

* fix: un-consume refresh token if minting the replacement fails

Greptile flagged a real reliability gap: cli_refresh_token blocks the
presented token atomically, then does several more DB calls before
returning a replacement (user lookup, team lookup, JWT mint, new
refresh-key mint). Since this endpoint exists specifically for fully
unattended apiKeyHelper operation, a single transient failure in that
window (DB hiccup, etc.) permanently stranded the user: their old
token was already dead and no new one was issued, with no recovery
path short of a full interactive browser re-login.

Wrap that window in try/except; on any failure, best-effort revert the
consumed token back to usable (blocked=False) before re-raising, so a
retry can succeed. Standard compensating-action pattern since
generate_key_helper_fn doesn't take an injectable transaction, so
wrapping the whole thing in a real DB transaction isn't practical here.

* fix(security): refresh key had unrestricted model access, not none

Critical bug: _mint_cli_refresh_token used models=[] intending "no LLM
access", but that's backwards in this codebase. Per
_check_model_access_helper: `len(filtered_models) == 0 and len(models)
== 0` -> all_model_access = True. An empty models list on a key with no
team_id means UNRESTRICTED access to every model, not zero access. The
CLI refresh token -- meant to be usable for nothing but silently
exchanging itself for a new JWT -- was actually a fully unrestricted
API key for its entire 90-day lifetime, completely undermining the
whole point of keeping it separate from the short-lived call
credential.

Fixed with two independent layers: allowed_routes hard-restricts the
key to exactly /sso/cli/refresh and /sso/cli/logout (the real enforced
boundary, checked in the shared user_api_key_auth dependency for every
route); models is set to an unmatchable sentinel string as
defense-in-depth in case any code path only consults the models field.

Added an end-to-end regression test that exercises the actual
model-access-control function against a key shaped like the minted
refresh token, rather than only asserting on what arguments were passed
to the key-generation call -- the latter kind of test is exactly what
let the original bug ship, since asserting `models == []` is equally
consistent with "no access" and "unrestricted access" without checking
what the access-control code actually does with that shape.

Also: the compensating-rollback added for reliability un-blocked a
consumed refresh token even when the underlying user no longer exists.
That's a permanent, intentional rejection, not a transient failure --
un-blocking it would let a stale refresh token become valid again for a
different account if the user_id is ever reused/re-registered. Moved
the user-existence check outside the rollback-on-failure block so it
stays permanently blocked.

* refactor: rotate CLI refresh tokens via regenerate_key_fn instead of hand-rolled consume/rollback

The refresh token is already a plain litellm virtual key, so rotation can
delegate to the same atomic DB update /key/regenerate uses instead of a
bespoke update_many + compensating-rollback dance. This makes silent CLI
refresh an Enterprise feature, same as regular key regeneration.

* refactor: replace CLI stateless JWT + refresh-key pair with one self-rotating virtual key

The CLI previously minted two credentials on login: a stateless self-signed
JWT for LLM calls, and a separate DB-backed refresh-only key (scoped away
from ever calling an LLM) just to authorize minting a new JWT. Collapse
this into a single real virtual key, used directly as the LLM bearer token
and re-presented to /sso/cli/refresh to rotate its own secret in place.

This also means the CLI session key now shows up in the Admin UI's Keys
page and can be revoked/regenerated like any other key, rather than being
an invisible, unmanageable stateless token.

* refactor: drop silent CLI refresh, key just expires and requires re-login

/sso/cli/refresh only ever benefited Enterprise deployments (regenerate_key_fn's
gate), while everyone else already fell through to "re-run lite login" on
failure. Cut the endpoint, the rotation logic, and the client-side refresh
path entirely; print-token now just prints the cached key until it hits its
LITELLM_CLI_JWT_EXPIRATION_HOURS duration, then fails fast telling the user
to log in again. Session key itself is unaffected: still a real, revocable
virtual key visible in the Keys UI, `lite logout` still revokes it directly.

* fix(ci): regenerate schema.d.ts after removing /sso/cli/refresh route

* revert: go back to stateless JWT, keep only lite auth print-token

The virtual-key redesign (revocable, Keys-UI-visible credential) wasn't
needed just to support print-token, and cost real server-side surface
(a mint path, a logout-revoke endpoint, migrated tests/docs) for a property
this repo doesn't need yet. Reverting cli_poll_key/_types.py/schema.d.ts
back to the original stateless-JWT design; the only durable addition from
this whole effort is `lite auth print-token` (reads the cached credential,
prints it while fresh, fails with a clear message once it's past
LITELLM_CLI_JWT_EXPIRATION_HOURS) plus the base_url_explicit plumbing it
needs. `lite logout` goes back to clearing the local file only, since a
stateless JWT can't be revoked server-side.

* refactor: move CLI token freshness check to cli_token_utils, drop unnecessary renames

Addresses review: the freshness check is a pure token-shape/timestamp
util, not command logic, so it belongs alongside the other SDK-level
CLI token helpers (load_cli_token, get_litellm_gateway_api_key) rather
than in commands/auth.py. Also reverted a few incidental jwt_token/
session_key variable and string renames that weren't load-bearing.

* fix(mcp): run the route gate on bridge admission so allowed_routes are enforced

The envelope arm reloaded the identity and ran _run_centralized_common_checks
but skipped RouteChecks.should_call_route, which the standard pipeline runs
between the builder and common_checks. Because the centralized checks treat MCP
as an inference route and never re-check allowed_routes, a key barred from MCP
routes could mint an envelope at the token endpoint (not itself an MCP route)
and replay it against MCP. Run the route gate before admitting, and clear the
request-scoped budget_reservation, matching the wrapper's sequence; a disallowed
route now surfaces the gate's own 403.

* fix(proxy): reserve budget for tiered pricing

Ensure tier-only models reserve their estimated request cost so concurrent requests cannot bypass exhausted budgets.

* fix(proxy): bill tier-only deployments instead of $0

Route cost calculation to the deployment's router_model_id entry when it carries tiered_pricing but no flat per-token rate, so models like dashscope/qwen3.7-plus are billed via their tier table rather than the pricing-stripped shared alias.

* refactor(ui): convert activity metrics charts to shadcn/recharts (#32726)

* refactor(ui): convert activity metrics charts to shadcn/recharts

Swap the seven tremor AreaChart/BarChart sites in activity_metrics.tsx to
the shared shadcn/recharts wrappers and switch CustomLegend/CustomTooltip
to the ported versions in shared/charts. Chart props, colors, formatters,
and legend behavior are unchanged; tests now assert on real recharts SVG
output instead of tremor mocks.

* fix(ui): restore tremor No data placeholder for empty AreaChart data

* test(ui): scope activity metrics chart assertions to card titles instead of render order

* feat(ui): extend topnav border across the sidebar header (#32920)

Pin the sidebar header to the same 56px height as the dashboard topnav and
give it a matching bottom border, so the two borders sit flush and read as one
continuous line. Revert to auto height when the rail is collapsed so the
stacked logo and toggle are not clipped.

* fix(cost): coerce string tiered-pricing costs and share tier helper

YAML-parsed tier costs can arrive as strings (e.g. "4e-07"), which broke
arithmetic in the graduated tiered-pricing calculation. Coerce per-token
costs to float in both the in-range and remaining-tokens paths.

Move the tiered-cost helper out of the Dashscope module into a
provider-neutral home so the proxy budget reservation no longer depends on
a provider-specific module.

Co-authored-by: Cursor <cursoragent@cursor.com>

* docs(anthropic): clarify the Opus 4.5 branch in adaptive-effort translation

Add an inline comment explaining that the effort-capable non-adaptive branch in
_translate_adaptive_effort_for_non_adaptive_model exists for models like Claude Opus
4.5 that accept output_config.effort but reject adaptive thinking, and why effort-only
requests pass through while adaptive requests with an unsupported effort level fall
through to the legacy translation.

* fix(anthropic): translate raw adaptive thinking for chat completions on pre-4.6 models

Clients that pass thinking={"type": "adaptive"} directly (not via the
reasoning_effort alias) on the /chat/completions interface had it forwarded
unmodified to pre-4.6 Anthropic models, which reject the shape. Mirrors the
translation already applied on the native /v1/messages passthrough (#32867):
translate to legacy thinking={type: enabled, budget_tokens}, capped below
max_tokens, dropping thinking when max_tokens can't fit even the minimum
budget. Hoists the shared budget-capping helper onto AnthropicConfig so both
paths use one implementation.

* fix(proxy): reserve tiered budget all-or-nothing across all deployments

Alibaba Model Studio (Dashscope) tiered pricing is all-or-nothing: the tier is
selected by a request's total input tokens and every token, input and output, is
billed at that one tier's rate. The reservation path used graduated slicing and,
worse, picked the output tier from the output-token count, so a long-context
request with a large output allowance reserved far less than the provider charges
and could slip past a depleted budget. Select the tier from input tokens and apply
its rates to all input and output tokens.

Reservation also read tiered pricing from only the first deployment in a model
group. A caller could hit an alias whose cheaper deployment was listed first and
exceed the budget once routed to a costlier sibling. Estimate against every
eligible deployment's pricing and reserve the maximum.

* feat(complexity_router): log the cause of each routing decision

The complexity router's info log didn't say what drove a routing decision.
Literal and semantic keyword matches logged an identical "keyword rule fired"
line (no way to tell which mechanism fired), and the scorer's line carried no
consistent marker tying it to the same question.

Emit one greppable line per decision naming the cause: literal_keyword_match,
semantic_keyword_match, or complexity_scorer. The hook already knows which ran
(the config's semantic_keyword_matching flag distinguishes lexical from
semantic; the override-vs-scorer branch distinguishes keyword match from
scorer), so this is label-only: no behavior change, no new types, no added
latency.

Adds regression tests asserting each decision path logs its cause; they fail if
a label is swapped or the cause= marker is dropped.

* feat(ui): add redesigned sidebar account menu (#32931)

* feat(ui): add redesigned sidebar account menu

Introduce SidebarAccountMenu, a sidebar-only account/logout menu built on
shadcn Popover/Switch/Badge/Separator/Button, and wire it into leftnav in
place of the shared UserDropdown. The panel has a LiteLLM header with the
bouncing moon and a clickable version tag, Tier/Role/Email/User ID rows
with copy actions, the five display toggles, and Logout.

UserDropdown is left untouched so the control-plane / chat navbar keeps
its existing menu. The version tag links to the same release notes page
as the navbar tag, and the bouncing icon reuses the existing header
animation gated by the Hide Bouncing Icon toggle.

* test(ui): point account-menu e2e specs at the migrated sidebar menu

The sidebar account menu moved from an antd Dropdown to a Base UI popover
(SidebarAccountMenu), so the login, logout, proxy-logout-url, and internal
user identity specs were still waiting on antd-era locators
(.ant-dropdown, the popupRender wrapper class, the user-dropdown-panel test
id, and a menuitem-role Logout). Point them at the new panel test id
(sidebar-account-menu-panel) and the button-role Logout instead. The logout
behavior is unchanged since both menus call the same useLogout handler.

* fix(bedrock-converse): translate adaptive thinking for pre-4.6 models

Follow-up to #32867 (native /v1/messages) and the /chat/completions
commit earlier on this branch, extending the same adaptive-thinking
translation to the Bedrock Converse path.

Clients like Claude Code send thinking={type: "adaptive"} on every
request. When routed via Bedrock Converse to pre-4.6 models
(claude-haiku-4-5, claude-sonnet-4-5), this was forwarded as-is and
rejected by the model. Mirrors the translation already applied on the
/chat/completions and /v1/messages paths: map to legacy
thinking={type: enabled, budget_tokens}, capped below max_tokens.

Also fixes the missing custom_llm_provider arg in the chat completions
path's call to AnthropicConfig._map_reasoning_effort.

* fix(mcp): run proxy-wide pre-DB gates on bridge envelope admission

The envelope arm bypasses user_api_key_auth, so it never ran
pre_db_read_auth_checks (request-size and body-safety limits, the IP allowlist,
and the general_settings route allowlist) that the normal MCP admission path
runs before any key lookup. A caller blocked by IP or a disallowed proxy route
could be admitted through an envelope where the same principal on the normal
path is rejected. Run those gates before the envelope crypto, mirroring the
pipeline's pre-DB ordering; a blocked IP or route surfaces its own 403.

* fix(anthropic): pass resolved provider to adaptive-thinking check

The rebase onto staging changed _is_adaptive_thinking_model to require
custom_llm_provider (no default), so the one-arg call in the raw adaptive
thinking branch raised TypeError at runtime for any /chat/completions
caller sending thinking={type: adaptive}. Use self._resolved_provider,
matching the reasoning_effort branch just below. Caught by Greptile.

* test(bedrock-converse): cover adaptive-thinking drop when max_tokens too small

Adds the regression test for the warning-drop branch in the Converse
adaptive-thinking translation, mirroring the chat completions path's
test_raw_adaptive_thinking_dropped_when_max_tokens_too_small.

* fix(guardrails): filter Add-Guardrail mode dropdown per provider (#32712)

* fix(guardrails): filter Add-Guardrail mode dropdown per provider

The GET /guardrails/ui/add_guardrail_settings endpoint returned every
GuardrailEventHooks value in one flat supported_modes list, so the Admin
UI rendered pre_mcp_call as a selectable Mode for every guardrail. Saving
Content Filter or Tool Permission with pre_mcp_call then failed with a
400 because those guardrails' server-side supported_event_hooks list
excludes it.

Expose each guardrail's supported hooks as a get_supported_event_hooks
classmethod on CustomGuardrail (mirrors the existing get_config_model
pattern) and have the endpoint iterate guardrail_class_registry to build
a supported_modes_by_provider map. The UI Mode dropdown filters by that
map when the selected provider is known and falls back to the global
list otherwise. __init__ now sources its own supported_event_hooks list
from the classmethod so the two sides can't drift.

Also register BedrockGuardrail, ToolPermissionGuardrail, lakera,
lakera_v2, and presidio in guardrail_class_registry so they participate
in the map (they were previously only in guardrail_initializer_registry
and had no class-registry entry).

Behavior change: guardrails that previously had no supported_event_hooks
declared (aim, javelin, azure/text_moderation, cato_networks,
crowdstrike_aidr, headroom, hiddenlayer, lasso, noma, onyx,
prompt_security, qualifire, repelloai, zscaler_ai_guard, aporia_ai,
lakera_ai, lakera_ai_v2, mcp_jwt_signer, model_armor, presidio) now
validate the configured mode at instantiation. Existing configs where
the mode was silently a no-op will fail at proxy startup with a clear
validation error rather than running as a broken guardrail.

Resolves LIT-4226

* fix(guardrails): add LITELLM_STRICT_GUARDRAIL_MODES escape hatch, preserve current mode in edit form

Address Greptile P1 (startup break) and P2 (edit form UX):

LITELLM_STRICT_GUARDRAIL_MODES defaults to true (raise on unsupported
event_hook, unchanged behavior for the guardrails validated pre-PR).
Setting it to false logs a warning and continues, giving deployments an
opt-out while they fix configs that now surface as errors instead of
silently no-op'ing. Regression test covers both modes.

Edit form now surfaces the currently-saved mode even when it is not in
the filtered per-provider list, so a legacy row (e.g. content_filter
saved with pre_mcp_call before this fix) no longer disappears from the
dropdown; the option renders with a 'not supported by <provider>' note
so the user knows to pick another.

* fix(guardrails): correct audited hook lists, prune stale modes on provider switch, clean form lint

Audited every get_supported_event_hooks classmethod against the hooks
each guardrail's own tests exercise and its handler methods. Five were
too narrow and their tests caught it in CI: rubrik gains pre_call,
presidio gains during_call and pre_mcp_call, prompt_security, onyx and
qualifire gain during_call. The remaining classes match either their
original __init__ declarations or their exercised modes exactly.

Cursor review fixes: the Add form now drops selected modes the new
provider does not support when the user switches providers, so a
pre_mcp_call selection cannot ride along into a provider that rejects
it at save; the edit form handles list-shaped stored modes instead of
treating mode as always a string.

Extracted shared toModeArray and getSupportedModesForProvider helpers
into guardrail_info_helpers so both forms use one implementation, typed
the remaining any usages in both forms, removed nested ternaries, and
committed the ratcheted-down eslint metrics and pruned suppressions

* fix(proxy): reserve tiered output at the higher reasoning rate

Some tiered Dashscope models price reasoning output above standard output
(output_cost_per_reasoning_token > output_cost_per_token). The reservation charged
all output at the standard rate, so a reasoning-heavy request reserved too little
and concurrent calls could exceed the budget before reconciliation. The reasoning
share is unknown before the request runs, so reserve every output token at the
higher of the two configured rates, for both tiered and flat pricing.

* refactor(ui): convert user agent and per-user usage charts to shadcn/recharts (#32725)

* refactor(ui): convert user agent and per-user usage charts to shadcn/recharts

Swap the tremor BarChart import for the shared shadcn/recharts wrapper in
user_agent_activity.tsx (DAU/WAU/MAU charts) and per_user_usage.tsx (usage
distribution histogram). All chart props are unchanged; the wrapper exposes
the same tremor prop surface with matching defaults.

Extend user_agent_activity.test.tsx and add per_user_usage.test.tsx with
parity assertions on the real recharts SVG output: bar series per category,
stacked x positions, resolved fill colors, axis bucket labels, legend text,
and value formatter output on axis ticks. Remove the dead ResizeObserver
polyfill in user_agent_activity.test.tsx now that the scoped global mock in
tests/setupTests.ts renders charts, which also lowers the no-explicit-any
metric by one.

* test(ui): harden bar x-position parsing against recharts path format

* feat(ui): working Test Connection for the complexity auto router

The consolidated auto-router tab dropped the Test Connection button because
the shared prepareModelAddRequest helper returns an empty array for an auto
router (it has no model_mappings), so the caller crashed destructuring
result[0].litellmParamsObj. That is the crash in #31590 and the open PR
#31794. #31794 only silenced the crash by pointing the test at
auto_router/complexity_router, which is not a provider model, so the
/health/test_connection health check (a real litellm.ahealth_check
completion) would still error.

Bring the button back and make it meaningful: an auto router dispatches to
saved model groups, so Test Connection now probes those directly. It builds
a deduped target list from the configured tiers (tiers sharing a model group
collapse to one probe) plus the embedding model when semantic keyword
matching is on, then runs a live /health/test_connection against each and
shows per-target pass/fail. This never touches prepareModelAddRequest, so the
original destructure crash cannot recur.

Scope is the recommended complexity router only; the to-be-deprecated
semantic router is untouched. No backend changes.

Supersedes #31794. Resolves #31590.

* refactor(ui): extract a shared CopyButton and fix the sidebar copy confirmation (#32945)

* fix(ui): show sidebar copy confirmation only on a successful write

The sidebar account menu's copy button switched to the checkmark
synchronously, before the clipboard write settled, so it confirmed a
copy that never happened when navigator.clipboard was undefined on
non-secure origins or when writeText rejected. The handler now guards
navigator.clipboard, awaits the write, and flips to the checkmark only
on success

Also updates the header accent emoji in the same menu

* refactor(ui): extract a shared CopyButton for the sidebar account menu

The copy-icon-to-checkmark pattern was hand-rolled in several places,
including the sidebar account menu whose private copy button held the
false-confirmation bug. Extract a single canonical CopyButton into
components/shared, built on the Button primitive with a guarded and
awaited clipboard write so the checkmark appears only on a real
success, and have SidebarAccountMenu consume it

The success and failure-mode coverage now lives in the shared
component's own test; the sidebar test keeps one case asserting the
email row is wired to it

* fix(ui): probe auto-router tiers via real proxy routing, not /health/test_connection

Live testing showed the first cut was broken: /health/test_connection merges
{...configParams, ...requestParams}, so passing the public model_group name as
the request model overrode the resolved provider model and every tier failed
with "LLM Provider NOT provided". The frontend only has the public group name,
not the underlying litellm_params, so it cannot build the request that endpoint
needs.

Switch to testing each model group the way production actually routes it: send a
minimal request to /v1/chat/completions (or /v1/embeddings for the embedding
model) by public group name through the shared apiClient. The router resolves
the group, credentials, and provider itself, so a green row means the tier is
genuinely reachable. Verified live: voyage embedding returns 200, a tier with a
bad key returns the real provider auth error.

Also address Greptile feedback: rows now update progressively as each probe
settles instead of all at once, and TIER_ORDER is derived through a
`satisfies Record<keyof ComplexityTiers, null>` guard so adding a tier without
listing it is a compile error.

* fix(completion): forward aws credential kwargs into litellm_params so the responses bridge keeps WIF auth

Chat-completions requests to responses-only Bedrock Mantle models are
bridged to the Responses API, but completion() forwarded only
aws_bedrock_project_id into get_litellm_params, so aws_role_name,
aws_web_identity_token, aws_session_name and the other SigV4 credential
kwargs never reached sign_request and botocore fell back to the default
credential chain ("Bedrock Mantle auth failed: no Bearer token and no
usable AWS credentials"). Forward the whole AWS credential kwarg family,
extracted from the OPTIONAL_KWARGS_KEYS set get_litellm_params already
supports.

* refactor(ui): convert entity usage and usage page charts to shadcn/recharts (#32729)

* refactor(ui): convert entity usage and usage page charts to shadcn/recharts

Swap the tremor BarChart/DonutChart render sites in EntityUsage,
SpendByProvider, TopKeyView, TopModelView, KeyModelUsageView and
UsagePageView to the shared shadcn/recharts wrappers. Convert the two
sole-chart Daily Spend cards and the KeyModelUsageView card to the
shadcn Card primitives.

Close the donut parity gap with strictly additive optional DonutChart
props: showLabel/label render a center total (tremor showed
valueFormatter(sum) by default) and startAngle/endAngle forward to the
Pie so both provider donuts keep tremor's clockwise-from-12 layout.
Defaults preserve the previous wrapper behavior.

DailyData and two site-local row types move from interface to type
alias so they satisfy the wrappers' Record<string, unknown> constraint;
interfaces lack implicit index signatures.

Tests now assert on real recharts output: bar/sector counts, cyan
fills, axis labels, donut center totals, and the TopKeyView bar-click
drill-down into the key info modal. The dead tremor chart mocks in
UsagePageView.test.tsx are removed and lint metrics/suppressions are
regenerated for the dropped tremor imports.

* fix(bedrock): allow bedrock-mantle:CreateInference in the web identity session policy

* fix(ui): drop max_tokens from the auto-router connection probe

max_tokens=1 makes reasoning models (o1/o3/...) return a 400 "max_tokens
reached" because reasoning tokens count against the cap, so a reachable
reasoning tier showed a false failure in Test Connection. Live-verified: o3
400s with the cap and succeeds without it.

Extract the request shape into a pure buildModelGroupTestRequest and cover it
with a test asserting the chat body carries no max_tokens (or
max_completion_tokens), so this regression is caught in unit tests instead of
only against a live reasoning model.

* feat(proxy): add expires filter to GET /key/list

Add an opt-in expires query param to GET /key/list so callers can fetch
only expired or only active keys without paginating every page and
filtering client-side. 'expired' matches keys whose expires is in the
past (NULL expires excluded); 'active' matches keys that never expire or
expire in the future. Omitting the param preserves existing behavior for
every caller. An unrecognized value returns HTTP 400 rather than silently
returning all keys.

The filter is pushed to the database via the existing Prisma where
builder so callers avoid pulling the full key table into application
memory.

derives the query key from method + path (dropping the hand-written

* feat(mcp): mint gateway-bound envelope at the token endpoint for dcr_bridge oauth_delegate

* feat(mcp): seal the authorizing key hash in the dcr_bridge envelope

The mint bound only user_id/server_id into the envelope, which gave admission
no way to reload the caller's key and enforce its current restrictions. Seal the
hashed authorizing key instead (a one-way digest, not a usable credential), so
admission reloads the live UserAPIKeyAuth by it and the key's team/org/tool
permissions and revocation apply per request.

Extract the token endpoint's key resolution into a shared _resolve_active_litellm_key
so the per-user token store (user_id) and the bridge mint (key hash) derive from one
active-key-gated path, and fail the mint closed with invalid_request when no active
key accompanies the request.

* fix(mcp): return 502 not KeyError when a bridge upstream response lacks access_token

The eager access_token = token_response["access_token"] extraction ran before
the dcr_bridge branch, so a missing upstream access_token raised an unhandled
KeyError and _bridge_grant_from_token_response's nil guard (which maps to a clean
502) was dead code. Move the extraction onto the non-bridge result path so the
bridge branch reaches its 502 guard.

* fix(mcp): let a keyless-user active key mint a bridge envelope

_resolve_active_litellm_key gated on _active_key_user_id, which returns None both
for blocked/expired keys AND for valid keys with no user_id, so a team-scoped or
service-account key was wrongly rejected with invalid_request at bridge token
exchange. Split the active-state gate (_key_is_active: blocked/expiry only) from
the user_id extraction; the mint seals the key hash, not the user, and admission
already handles a keyless-user key. The per-user token store still gets no user
for such a key, as there is none to key a stored credential by.

* style(mcp): use X | None annotations on the touched key-resolution helpers

The keyless-user fix moved these signatures, so their pre-existing Optional[...]
annotations counted against the diff and tripped the UP045 strict-budget gate.
Modernize the four touched return annotations to the X | None form the gate
wants; runtime behavior is unchanged.

* fix(mcp): coerce numeric expires_in and make the active-key check total

Two correctness gaps in the bridge mint. _bridge_grant_from_token_response only
accepted an int expires_in, dropping a float (3600.0) or numeric-string ('3600')
lifetime to None so the envelope fell back to its 1h cap and could outlive a
shorter-lived upstream token; coerce it to a positive int (bool excluded). And
_key_is_active called datetime.fromisoformat on the str|datetime expires outside
the resolver's try, so a malformed stored expiry raised an unhandled 500 instead
of the fail-closed invalid_request; it now fails closed (inactive) on an
unparseable expiry. Regression tests cover int/float/string/bool coercion, the
short-float TTL, and the malformed-expiry fail-closed path.

* fix(mcp): harden the bridge token mint (multi-lens review pass)

Findings from a full adversarial review of the mint path across security,
correctness, error-handling, concurrency, and OAuth-protocol dimensions.

- expires_in coercion is now total: int(float(...)) can raise OverflowError on
  Infinity / a giant numeric string, which escaped the ValueError/TypeError catch
  and 500'd the token endpoint. Unified to catch OverflowError too.
- Resolve the litellm identity BEFORE exchanging the single-use upstream code, so
  a missing or transiently-unresolvable identity fails closed with invalid_request
  without burning the code (the mint re-resolves via a cache hit).
- The no-identity failure is now an RFC 6749 5.2-shaped invalid_request
  (JSONResponse, top-level error, no-store) instead of a detail-wrapped
  HTTPException, matching the BYOK OAuth endpoint.
- EnvelopeTooLarge (upstream token too big to seal) surfaces a 502, not a 500.
- The upstream refresh_token is no longer sealed into the envelope: the edge
  never consumes it, so it was dead weight embedding a long-lived upstream
  credential in the client bearer and enlarging the envelope; refresh is a
  follow-up (a dedicated refresh-envelope).

Security review found no exploitable defect (forgery, cross-server/user replay,
leakage, confused-deputy all closed). Regression tests cover the OverflowError,
the code-not-burned path, the RFC-shaped error, the 502, and the dropped refresh.

* fix(mcp): close the burn-before-check gate for both grants and validate master_key first

Follow-up to the pre-exchange identity gate, which I had only added to the
authorization_code branch and which left the master_key check inside the mint
(after the upstream exchange) - so the very burn-then-fail pattern it was meant to
prevent still applied to refresh_token grants and to a misconfigured gateway.

- Hoist a single pre-exchange gate above the upstream call that covers BOTH grant
  types: it fails closed (invalid_request) on an unresolvable litellm identity and
  500s on an unset master_key BEFORE the single-use code or refresh token is
  exchanged/rotated, so a bad key or a misconfigured gateway never burns the
  upstream credential.
- Report expires_in from the envelope JWT's own second-truncated exp (rounding the
  elapsed portion up) instead of the raw expires_at - now delta, so the client is
  never told the bearer is valid past the ~1s point admission already expires it.

Regression tests assert the upstream exchange is never called on the no-identity
refresh grant and the master_key-unset path, and that the reported expires_in does
not overstate the JWT exp.

* refactor(mcp): make the bridge delegate mint a phased failures-as-values pipeline

The dcr_bridge oauth_delegate token mint validated its preconditions in two
places: a pre-exchange guard inside exchange_token_with_server (master_key set,
resolvable litellm identity) and an authoritative re-check inside the post-exchange
_mint_bridge_delegate_token_response. Keeping the two in step by hand is what kept
producing the same class of finding: a precondition guarded on one grant branch but
not the other, master_key checked after the exchange on one path, identity resolved
twice, and each failure raising an ad-hoc HTTPException with its own status and body
shape.

Model the mint as three phases whose failures are values. _prepare_bridge_mint runs
before the exchange, checks every precondition once (master_key, then identity), and
returns either a frozen _BridgeMintReady carrying the resolved key hash and the
master-key-derived envelope keys, or a _BridgeMintError literal. Because every
precondition lives in prepare, and prepare runs before the upstream POST, no failure
can burn the single-use code or rotate a refresh token, for either grant type, by
construction rather than by a guard we have to remember to keep in sync.
_finish_bridge_mint runs after the exchange and has no preconditions left that can
fail; its only failure values are properties of the upstream response itself (no
usable access_token, or a token too large to seal). One mapper,
_bridge_mint_error_response, turns each _BridgeMintError into an RFC 6749 section
5.2-shaped body with a status truthful about where the failure is (400 for the
caller, 500 for gateway config, 502 for the upstream), with an exhaustive match plus
assert_never so a new failure mode cannot be added without a matching status.

Behavior is unchanged for the client. Every failure that previously raised now
returns the same status as an OAuth error body, which is the correct token-endpoint
contract; the three tests that asserted a raised HTTPException now assert the
returned response. _exchange_for_bridge_server additionally asserts the identity
resolver is awaited exactly once for a bridge server and never for a non-bridge one.

* fix(mcp): let the bridge envelope report expires_in 0 at the jwt exp boundary

_finish_bridge_mint floored the reported expires_in at 1. Admission expires the
envelope against the JWT's second-truncated exp, so when the mint lands in the same
second that exp falls on (a sub-second upstream lifetime, for instance), the true
remaining life is 0 and reporting 1 tells the client the bearer lives one second past
the point admission already rejects it. Floor at 0 instead so the reported lifetime
never overstates the exp; the value still cannot go negative.

The regression pins the boundary directly: minting at now=100.25 with a 1s upstream
token seals exp=101, and the reported expires_in is max(0, 101 - ceil(100.25)) = 0.
Under the old floor of 1 it reads 1, so the test fails on that mutation.

Also drops the unused mcp_server parameter from _prepare_bridge_mint; identity and
key derivation there never referenced the server.

* refactor(mcp): make bridge-mint resolvers return tagged unions so status is truthful by construction

Three findings landed together, all one defect: a resolution step crushed several distinct outcomes
into a single None or a silent default, so the mint's error mapper could not tell them apart and
assigned the wrong status. Identity resolution mapped a database outage to the same None as a missing
credential, which the mint reported as 400 invalid_request, blaming the caller for a gateway outage
while admission statuses the same outage 503/500. Lifetime coercion mapped an explicit non-positive
expires_in to the same None as an absent one, so an upstream token the IdP reports as already dead was
sealed into an hour-long envelope. And the refresh_token grant was run through the upstream exchange
(which can rotate the client's upstream refresh credential) and its result then discarded, even though
a bridge server seals no refresh_token and the client never holds one to present.

Rather than add a mapping branch per finding, the fix changes the return types so a wrong status is not
representable. Each resolution step now returns a precise tagged value instead of None: identity
resolution returns a _ResolvedKey or one of no_active_key / unavailable / unresolvable, classified the
same way admission's _reload_admitted_key classifies the same conditions; upstream-lifetime
classification returns a positive number of seconds, "unspecified" (absent or unparseable, which the
envelope caps), or "expired" (a parseable non-positive value, an already-dead token); and upstream-grant
validation returns a typed grant or one of no_access_token / expired_lifetime. Thin exhaustive mappers
(match plus assert_never) lift each vocabulary into one bridge-mint taxonomy of eight named failures,
and a single _bridge_mint_error_response gives each its truthful RFC 6749 §5.2 status: 400 for the
caller's missing credential or an unsupported grant, 503 for a transient auth-DB outage, 500 for a
gateway that cannot resolve identity or is not configured, and 502 for an upstream response with no
usable token, an already-expired lifetime, or a token too large to seal. Adding a failure mode now
requires a new literal and a match arm the type checker forces, so the class of wrong-status bug cannot
recur silently.

The refresh_token grant is rejected in _prepare_bridge_mint before the exchange with
unsupported_grant_type, so it can never rotate or consume the client's upstream refresh credential;
renewal is re-running authorization_code, as the sealed refresh_token=None already intends. An absent or
unparseable expires_in still mints a capped envelope (the by-design behaviour for an upstream that omits
the field); only an explicitly-dead lifetime is rejected.

Tests cover the resolver's three failure classes (including a real connection-error outage and a missing
prisma_client), the mint statuses for each (503 before the upstream exchange, 500, 502 on an expired
upstream lifetime, and a capped mint on an unknown one), and the refresh-grant rejection before any
exchange. The three findings are mutation-checked: reverting each fix turns its regression test red.

* fix(mcp): treat a positive sub-second upstream lifetime as alive, not expired

_classify_upstream_lifetime decided "expired" from int(float(expires_in)), which truncates toward
zero, so a positive fractional lifetime in (0, 1) became 0 and was misread as already elapsed. That
rejected the mint with 502 in _finish_bridge_mint after the single-use upstream code had already been
consumed, even though the upstream reported a positive remaining lifetime.

Decide expired on the parsed numeric value rather than its truncated int, so only a genuinely
non-positive value is expired. The envelope works in whole seconds and cannot represent a sub-second
lifetime, so a positive value that truncates to 0 clamps up to the 1s floor instead of being rejected.
Values >= 1 still truncate toward zero so the envelope never claims more life than the upstream stated,
and NaN / Infinity / oversized input still read as unparseable ("unspecified").

Regression covers the classifier (0.5 and 0.001 clamp to 1, 1.9 truncates to 1, -0.5 stays expired) and
the mint (a 0.5s upstream lifetime mints a 200 envelope rather than a 502); reverting to the
truncate-then-check reddens both.

* fix(auto_router): inline error for missing LLM classifier model

Selecting the LLM classifier without picking a model only surfaced a
toast on submit; the classifier model select now gets the same red
outline and helper text as the tier and embedding selects once a submit
attempt has failed.

* feat(router): add Router(plugins=[...]) routing-plugin pipeline (#32972)

* feat(router): add Router(plugins=[...]) routing-plugin pipeline

Runs a sequence of user-supplied plugins before the routing decision is
made. Each plugin reads/mutates a RoutingContext (messages, candidate
models, metadata, signals); the narrowed candidate list is enforced when
picking a deployment, raising rather than silently falling back if a
plugin narrows to zero candidates.

Prototype for the routing-plugin pipeline discussed in #32168.

* fix(router): use ruff-modern typing, add raw/structured messages to RoutingContext

- Use dict/list/X|None instead of Dict/List/Optional in new code, staying
  within the ruff strict-rule budget ratchet
- Extract the guardrail-translation message normalization ComplexityRouter
  already had into a shared resolve_structured_messages() helper
  (litellm_core_utils/prompt_templates/factory.py), reused by
  ComplexityRouter and the new routing-plugin pipeline instead of
  duplicating it
- RoutingContext now exposes both raw_messages (as received) and
  structured_messages (normalized across chat completions / Anthropic
  messages / Responses API), mirroring CustomGuardrail.apply_guardrail's
  pattern, per review feedback on #32972
- Add direct unit tests for _run_routing_plugins and
  _filter_by_routing_plugin_candidates (router_code_coverage gate requires
  every router.py function be called by name somewhere in tests/)

* fix(test): rename to test_router_routing_plugins.py

router_code_coverage.py's AST scanner only inspects test files whose
filename contains the substring "router" -- test_routing_plugins.py
doesn't match (routing != router), so it silently skipped this file
and flagged _run_routing_plugins/_filter_by_routing_plugin_candidates
as untested despite the direct unit tests added for them.

* fix(router): fail closed when plugins are configured but the resolved
routing path can't run them

Router.completion() (and other sync entry points) resolves deployments
via the synchronous get_available_deployment(), which never runs
async_pre_routing_hook and therefore never runs the routing-plugin
pipeline. async_get_available_deployment() itself falls back to that
same synchronous method for routing strategies without an async-native
selector (e.g. legacy "usage-based-routing" v1). Both paths would let a
policy plugin (e.g. a deny-all rule) be silently bypassed.

Raise instead of silently proceeding when self.routing_plugins is
configured and the sync path is reached, since applying the pipeline to
every selector path is a larger change out of scope for this PR.

* fix(responses): continue MCP gateway tool turns from the final response and surface failures

When a /responses request uses a hosted MCP tool (server_url: litellm_proxy/<label>)
with store=true and the model calls a tool, the gateway auto-executes the tool and
streams one logical response stitched from several upstream responses: an interim
response whose only output is the function_call, then the post-tool answer

B1 (correctness): every streamed event was pinned to the first round's response id,
i.e. the interim response that carries the function_call but no tool output. The
client then continued the next turn from that dangling response and the provider
rejected it with "No tool output found for function call <id>", which on the
streaming path surfaced as a silent empty completion. The fix adopts each
auto-execute round's own response id (the cached id is reset when a follow-up round
starts) so the client continues from the final round, whose stored input chain
includes the function_call_output

B2 (robustness): initial and follow-up call failures were swallowed; the stream
emitted the mcp_list_tools discovery events and then closed with HTTP 200 and no
output and no error. The fix stashes the failure, makes the initial call eagerly in
aresponses_api_with_mcp so a pre-stream failure re-raises as a real 4xx before any
SSE bytes are written, and emits a terminal error event when a follow-up call fails
mid-stream

Adds regression tests covering continuation exposing the final round's response id
rather than the interim tool-call id, a follow-up failure emitting a terminal error
event, and an initial-call failure being stashed for eager re-raise

CheckBatchCost skipped Bedrock batches whose unified_object_id is a raw

unmanaged Vertex batches. Bedrock batches embed the model name in their
s3:// input file name instead (litellm-bedrock-files-{model}-{uuid}.jsonl),
so the same routing mechanism now derives the model from that layout and
matches it to a configured bedrock deployment.

track_unmanaged_vertex_batch_cost is renamed to track_unmanaged_batch_cost
since two providers now share this mechanism.

* fix(batches): parse Bedrock batch output and price with deployment model name

Bedrock model-invocation-job results use modelOutput/error rows and short
internal model ids that are not in the cost map, so unmanaged batch cost
tracking logged tokens but $0 spend. Use deployment model name for pricing
and add regression tests.

Co-authored-by: Or Gershoni <org@lasso.security>

* feat(mcp): generalize the bridge envelope identity to a key_hash or user_id subject

The scripted two-header client mints under a virtual key it presents at the token
endpoint (key_hash), but the interactive DCR client authenticates via SSO at the
bridged authorize, which yields a user, not a key. Make EnvelopeIdentity a
discriminated subject (subject_type key_hash | user_id) with key_hash_identity /
user_identity constructors, and dispatch admission on it: a key_hash reloads the
key, a user_id reloads the user and admits them as themselves (user-level budget
and SCIM enforced via the same centralized gate; no team bound, since a user
belongs to many teams or none). The interactive producer that mints a user_id
envelope lands in the follow-up commit.

* feat(mcp): interactive SSO sign-in for dcr_bridge oauth_delegate DCR clients

Completes the oauth_delegate bridge for real DCR clients (Claude Code, Claude
Desktop), which send no litellm key and cannot use the scripted two-header path.
On the short-circuit bridge arm the gateway now captures the SSO-authenticated
litellm user from the browser session at /authorize and seals it into the OAuth
state; at /callback it seals that user plus the upstream code into a gateway
authorization code the client echoes back; at /token it recovers the user,
exchanges the real upstream code, and mints a user-subject envelope. The user
identity captured in the browser thus rides to the back-channel token call with
nothing stored server-side, and admission opens the envelope under that user. The
scripted key_hash path is unchanged (raw upstream code, key from the request);
without a session the browser is sent through login first.

* fix(mcp): classify the user-subject reload's errors like the key path (503 outage, 401 missing)

_reload_admitted_user mirrored only part of _reload_admitted_key's error contract: it caught
ProxyException and HTTPException but had no arm for anything else, so a transient DB outage surfaced as
an opaque 500 instead of the retryable 503 the key path guarantees, and a missing user surfaced as a 500
too. The missing-user case is the subtle one: get_user_object raises a bare Exception for a deleted user
(not a ProxyException like get_key_object does for a missing key), so the ProxyException/HTTPException
clause never caught it and the user_object-is-None branch it was supposed to hit is unreachable on the
production path.

Add the same except-Exception arm the key path uses, with the one deliberate difference the differing
get_user_object contract requires: a database-service-unavailable error still raises the retryable 503,
while a missing user or any other non-outage resolution failure fails closed as a 401 rather than
propagating as a 500. The regression tests now drive the real behavior (get_user_object raising) rather
than a None return that never happens in production, and cover both the 503 outage and the 401
missing-user paths.

* fix(mcp): admit a user-subject envelope with the user's own MCP object permission

_reload_admitted_user returned a bare UserAPIKeyAuth(user_id=...), so the shared
get_allowed_mcp_servers found no key/team/object-permission grants and an interactive SSO client could
admit successfully yet see zero tools on a normal (allow_all_keys=False) server. The key path returns
the full key record whose object permission drives that computation; the user path dropped it.

Resolve the user's own MCP object permission and put it on the returned auth, so the same
get_allowed_mcp_servers the key path uses grants the user their litellm-granted servers and access
groups. This reuses get_object_permission (the id-to-grants resolver keys and teams already use) and
does not duplicate any permission logic; get_user_object does not load object_permission, so it is
resolved from the user's object_permission_id the same way the key and team paths do.

Only the user's own object permission is bound. A UserAPIKeyAuth carries a single team_id while a user
may belong to many teams, so team-inherited MCP grants for a user are a follow-up: they need a
many-teams union get_allowed_mcp_servers does not do off one auth object, and faking one here would be
the kind of half-measure that spawns more bugs. Tests cover the user's object permission riding onto the
admitted auth, and the existing admit/SCIM/missing-user/503 cases still hold.

* feat(ui): rebuild the Virtual Keys table on the shared DataTable

Replaces the hand-rolled Tremor table and bespoke toolbar/pagination on the admin
Virtual Keys page with the shared DataTable: server-side sort, paginate, and
filter, a sticky scrolling body, a search plus column-visibility plus filters
toolbar, a right-side filter drawer, and a rows-per-page footer. A page header
with the existing key icon carries the Create New Key action.

Adds reusable, shadcn-default building blocks for the tables migrating onto the
DataTable next: shared IdentityCell, ModelsCell, and SpendBudgetCell in
shared/table_cells, plus a shared PageHeader. The models cell reveals overflow in
a hover tooltip and the spend/budget cell uses the Meter primitive.

All data and domain logic is preserved, including the useKeys query, team and org
alias resolution, the user popover, and the KeyInfoView detail swap. The rich
async Team/Org/Alias filters move into the drawer, and the toolbar search maps to
the key-alias substring search. Status now also reflects key expiry alongside
blocked and SCIM-blocked.

The VirtualKeysTable tests are updated to the new markup and extended with focused
coverage for each new shared cell

* fix(ui): address Virtual Keys redesign review feedback

Fold the status badge into the clickable Key cell and drop the separate Status
column so a key's alias, secret, and status read as one unit. The Key cell is

removed

Migrate the filter drawer off AntD to shadcn. A new Combobox composed from
Popover and Input backs the Team, Organization, and Key Alias filters, keeping
search and the alias infinite-scroll

Show $0.00 for zero spend instead of a hyphen, and extend the shared DataTable

/key/list rejects with 400. It now sorts by the backend field key_alias

* fix(ui): use the shadcn base combobox and refine the keys filters and skeletons

Replace the hand-rolled filter combobox with the supported shadcn Base UI combobox
(ui/combobox, added via the CLI and reused through a small SearchSelect wrapper).
Its vended input-group and textarea deps are written for React 19 (plain functions
with ref-as-prop); this app is on React 18, where those subcomponents drop the refs
Base UI passes for focus and anchoring, so InputGroupInput, InputGroupButton, and
ComboboxTrigger are adapted to forwardRef. Those ui/ files now diverge from the
registry, and a future shadcn add would overwrite the adaptation until the app moves
to React 19. Adds class-variance-authority, which input-group needs

Give loading skeletons a per-column renderSkeleton escape hatch on the shared
DataTable and mirror the Key cell exactly (alias line, secret, status pill), so
skeleton rows match the real rows instead of being shorter and simpler

Resolve the automated review: the toolbar search and the drawer Key Alias filter
both mapped to the key-alias query, so the search silently overrode the drawer value
while its chip stayed visible. Consolidate to a single alias search in the toolbar
(placeholder now "Search by key alias…") and drop the redundant drawer field. Re-add
coverage for the Created By column's alias-over-email display

Refine the Team and Organization filters: they match on name and id, so the labels
read "Team" and "Organization" rather than "... ID", each option shows the name with
the id on a muted second line instead of "name (id)", and the active-filter chip

* fix(mcp): relay upstream OAuth token and DCR rejections instead of a generic 500

An upstream token endpoint rejection (e.g. Google requiring client_secret even for PKCE web clients) escaped exchange_token_with_server as a raw httpx.HTTPStatusError, which the global exception handler turned into an opaque 500 Internal server error in the create-flow UI. The RFC 6749 section 5.2 error body the IdP sent (error, error_description, error_uri) is now relayed with the upstream's own 400/401 status; rejections outside the section 5.2 contract map to 502 so a broken upstream is not misattributed to the caller. The same relay covers the non-bridge DCR registration arm, and a 200 token response without a usable access_token now answers 502 instead of a KeyError 500. The catch wraps the post call itself because litellm's AsyncHTTPHandler raises MaskedHTTPStatusError at call time, which also made the pre-existing bridge-relay status check unreachable in production. The dashboard's token exchange error message now composes error and error_description so the form shows the IdP's reason

* refactor(mcp): drop bridge relay status check made unreachable by the unified relay

The try/except around the registration post now relays every upstream 4xx/5xx for both arms, so the bridge_relay status_code check could never fire; removing it addresses the Greptile P2 dead-code finding

* fix(mcp): classify get_user_object's wrapped DB outage across the exception chain

get_user_object catches every DB failure in a broad except and re-raises a bare ValueError (litellm/proxy/auth/auth_checks.py), so a real outage and a missing user look identical and the original error survives only as __context__. The dcr_bridge admission path keyed its 503-vs-401 decision on the exception type, so a transient outage during a user-subject reload surfaced as a 401 rather than a retryable 503, and the regression test injected a raw ConnectionError, a shape get_user_object never produces, so it passed on a fiction

Add PrismaDBExceptionHandler.is_database_service_unavailable_error_in_chain, which walks __cause__/__context__ (bounded and cycle-safe) the PEP 3134 way, and route _raise_503_if_db_unavailable through it. Move the user's object_permission resolution inside the single classified try so an outage there is a 503 too, never an opaque 500. Pin get_user_object's wrapping with a contract test that drives the real function, and drive the reload tests with that same faithful shape so a chain-blind regression fails them

* fix(ui): address Virtual Keys redesign review nits

Restore sorting by budget on the merged Spend / Budget column. The column now
uses a new DataTableMultiSortHeader whose chevron opens a menu offering Spend
and Budget in both directions plus Reset, so the progress-bar cell stays merged
while the sort field becomes an explicit choice. Sorting is server-side, so the
chosen field id (spend or max_budget, both accepted by /key/list) flows straight
through as sort_by

Fill the DataTable to its container width when column resizing is on. The table
width was pinned to the sum of column widths, so hiding columns left an empty
gutter on the right. It now keeps that width as a minimum and stretches to 100%
on underflow while still scrolling on overflow, which also covers the same gap
in TeamVirtualKeysTable since both share the component

Drop the dark background box behind the page-header icon so the Virtual Keys
header reads like the Teams header, and pull the 4-line inline filter lambda in
SearchSelect out into a named matchesQuery helper

Extends the DataTable and VirtualKeysTable tests to cover the new multi-field
sort menu (field id maps to sort_by, active indicator, reset) and the
fill-to-container width

* fix(ui): emphasize the active field in the Spend / Budget sort header

The merged Spend / Budget header always read "Spend / Budget" regardless of
which field drove the sort, so after picking Budget descending there was no way
to tell what was sorted without reopening the menu. The header now builds its
label from the sort fields and emphasizes whichever one is active (bold,
full-strength text) while muting the other, so the sorted column reads at a
glance alongside the direction chevron. Drops the now-redundant title prop since
the label is derived from the fields

* fix(ui): remove w-full so the keys page content stops overflowing by 32px

The virtual keys content wrapper used "w-full mx-4", which sets the width to
100% of the parent and then adds 16px of horizontal margin on each side, so its
margin-box came to 100% + 32px and overflowed the scrollable main region by
exactly 32px. That surfaced as a horizontal scrollbar along the bottom of the
whole content area, under the pagination. A block div is already full-width, so
dropping w-full lets mx-4 inset it correctly with no overflow

* fix(ui): darken the clickable Key cell on hover so it reads as clickable

The Key cell was the click target that opens the key detail, but hovering only
faded the chevron in with no change to the cell itself, so there was no cue that
the area was clickable. Give the cell a subtle muted background and a pointer
cursor on hover. The button spans the full cell (a negative inline margin plus a
matching width offset so the hover fill reaches both cell edges while the title
stays aligned with the other columns)

* fix(openai/responses): clamp max_output_tokens below API minimum (#33098)

* fix(openai/responses): clamp max_output_tokens below API minimum

Claude Code sends a max_tokens=1 warmup probe when running /model, which
the Anthropic Messages -> Responses adapter forwards as max_output_tokens=1.
OpenAI's Responses API rejects values below 16, so the probe failed with a
400. Clamp anything below the minimum up to 16 in map_openai_params so all
Responses API entrypoints (direct, chat->responses, anthropic->responses)
are covered.

* fix(prometheus): read v3 rate limiter remaining values for per-key model gauges (#33119)

* fix(ui): drop w-full from page-content wrappers to remove 32px horizontal overflow (#33118)

Several dashboard pages wrap their content in a div styled w-full mx-4, so the
element's width is 100% of the scrollable main while mx-4 adds 16px of margin on
each side. That makes the margin-box 100% + 32px wide, which overflows main by
exactly 32px. Because main uses overflow-y-auto its overflow-x computes to auto,
so the overflow surfaces as a horizontal scrollbar along the bottom of the whole
content area under the pagination

The wrapped block is already full width without w-full, so removing that one
token keeps the layout and drops the overflow to 0. This is the same fix already
applied to the Virtual Keys page in #33112, extended to the remaining pages that
share the wrapper: Models + Endpoints, Tag Management, Organizations, Vector
Stores, AI Hub, and Logging & Alerts

* feat(mcp): client-held refresh envelope for the dcr_bridge oauth_delegate flow

A dcr_bridge oauth_delegate access envelope is capped at one hour, and until now the mode had no refresh
at all: when the envelope expired the client had to re-run the interactive authorization_code flow. This
adds a second client-held credential, the refresh envelope, so the client renews on a back channel and
only re-authenticates when the refresh envelope expires or the upstream refresh token dies.

The refresh envelope is a distinct llm_refresh_ credential that seals only the upstream refresh token
(never the access token) bound to the same litellm identity and MCP server as the access envelope, under
the same master-key-derived keys, with nothing stored server-side. Both envelopes now carry a signed
kind claim ("access" or "refresh") that open() requires to match, so a refresh envelope can never open as
an access credential even if its wire prefix is swapped (the prefix is not signed; the claim is). A
refresh envelope presented at the MCP tool-call edge is not an access envelope, so admission fails it
closed the same way it already fails any non-access bearer.

At the token endpoint the authorization_code mint now returns a refresh envelope alongside the access
envelope whenever the upstream returned a refresh token, and the refresh_token grant is supported for
bridge servers: the client presents its refresh envelope, the endpoint opens it, re-validates the sealed
litellm key so a revoked key cannot keep refreshing, unwraps the real upstream refresh token, exchanges
it with the upstream IdP, and returns a fresh access envelope. Because the endpoint re-seals a refresh
envelope only when the upstream returns a new refresh token, the design mirrors the upstream's own
rotation policy rather than reinventing it: with a rotating upstream the client rotates and reuse is
detected upstream; with a non-rotating upstream the original refresh envelope stands until its bounded
14-day TTL. Both preconditions and the unwrap run before the exchange, so a rejected refresh never
consumes or rotates an upstream token.

The pure envelope and credential layers stay side-effect free: mint/open share one signing, size, and
kind gate across both envelope kinds, and every failure is a value. Tests cover the refresh round-trip,
the kind-claim and server-id bindings, the revoked-key gate, upstream rotation carried through, the
unwrap sending the real upstream token upstream, and edge rejection of a refresh envelope; the three
security bindings are mutation-checked. Limitation documented in the PR: gateway-enforced refresh
rotation with reuse detection would require server-side state, which this zero-custody mode omits by
design, so the refresh envelope inherits the upstream's rotation posture plus gateway identity binding
and a bounded TTL.

* fix(mcp): reject a refresh envelope explicitly at the tool-call edge

The live proof showed a refresh envelope presented at the MCP tool-call edge was rejected, but through
the generic oauth2 arm ("expected a virtual key starting with sk-") rather than the bridge arm, because
the admission routing gate is_bridge_envelope_shaped matched only the access prefix. The rejection was
already fail-closed and never forwarded anything upstream, but the path was imprecise and the unit test
modelled a route the real router did not take.

Match either envelope kind in is_bridge_envelope_shaped so the bridge arm engages for a refresh envelope
too, and have resolve_bridge_envelope return BridgeEnvelopeInvalid for it: a refresh envelope is a valid
gateway credential but only ever presented back to the token endpoint, never usable to authenticate a
tool call. Admission now fails it closed with the bridge arm's own 401 ("Invalid or expired
credential"), live-verified, with the upstream never touched. is_bridge_envelope_shaped has a single
caller (the admission routing gate), so the change is contained.

* fix(mcp): SecretStr the unwrapped refresh token, drop the dead request arg, fail closed on a missing user

Three review findings on the refresh path, addressed at the root:

_BridgeRefreshReady.upstream_refresh_token was a plain str, the one credential in the envelope/bridge
layer that escaped the SecretStr discipline every other one follows (RefreshCredential.refresh_token,
UpstreamTokenGrant.access_token, EnvelopeKeys.signing_key). A repr or a traceback capturing a local
_BridgeRefreshReady would have logged the raw upstream refresh token. It is now a SecretStr, carried as
the SecretStr open_bridge_refresh_envelope already returns and unwrapped only at the point the exchange
builds the upstream request body.

_prepare_bridge_refresh took a request it never read; on the refresh path identity comes entirely from
the sealed envelope, not the HTTP request, so the parameter was dead and misleadingly implied it read
from the request the way the authorization_code prepare does. Removed, and the caller updated.

_reload_active_user_by_id misclassified a missing user as unresolvable (500). This is the same root
cause as the admission user-reload fix: get_user_object raises a bare Exception for a deleted user
rather than a ProxyException, so its except-Exception arm must fail closed to no_active_key (which the
refresh path maps to invalid_grant) for anything that is not a database-service-unavailable outage,
rather than treating a missing user as an opaque gateway fault. Regression tests cover the missing-user
and DB-outage classifications directly.

* fix(mcp): make the dcr_bridge refresh path fail correctly on outages, dead tokens, and revoked owners

Four fixes to the refresh_token grant for dcr_bridge oauth_delegate, surfaced by an adversarial pass over the exchange path

Route the user-subject re-validation's outage check through the chain-aware classifier, so a transient DB outage (which get_user_object wraps in a bare ValueError) reports as unavailable (a retryable 503) rather than collapsing to no_active_key and an invalid_grant, matching how admission now handles the same wrapper

When the upstream reports its own refresh token as already elapsed (refresh_expires_in non-positive), do not seal it into a full-TTL refresh envelope; return no refresh so the exchange degrades to an access-only response, mirroring how the access grant refuses an already-elapsed access token instead of capping it

When the upstream rejects the sealed refresh token with 400 invalid_grant (revoked or expired at the IdP), return an RFC 6749 invalid_grant response so the OAuth client re-runs authorization_code, rather than surfacing the opaque upstream error it cannot act on

Gate key-subject renewal on the owner's SCIM state, mirroring admission's _reject_if_admitted_owner_scim_deactivated, so an offboarded user cannot keep refreshing a still-active key; the check fails open on a missing owner or a DB blip so a key that outlives its owner record does not get wrongly revoked

Each fix has a mutation-checked regression test

* test(proxy): add regression tests for management_endpoints edge cases (#32976)

Mutation testing surfaced branches in cost_tracking_settings and common_utils that the suite executed but never asserted on. Pin those behaviors with targeted tests: the returned (model, provider) from _resolve_model_for_cost_lookup for deployments carrying a custom_llm_provider and for deployments missing the litellm_params / model_info keys, plus the exact error-response bodies, the caller-identity lookup arguments, and the member and guard branches in common_utils.

* fix(auto-router): correct Responses API tool_choice shape and propagate alias litellm_params (#32974)

* fix(anthropic-messages): send bare-string tool_choice to Responses API, propagate router-alias litellm_params

The Anthropic /v1/messages -> Responses API adapter always wrapped
tool_choice in an object ({"type": "auto"}, {"type": "required"}), but
the Responses API's tool_choice schema for these cases is a bare
string ("auto"/"required"/"none"). Sending the object shape to an
OpenAI-compatible backend (e.g. vLLM) fails Pydantic validation with a
400. The "none" case also fell through to "auto" instead of mapping to
"none".

Separately, litellm_params configured directly on a router-alias
deployment (auto_router/complexity_router, adaptive_router,
quality_router, or semantic auto_router) - e.g.
cache_control_injection_points, drop_params - were silently dropped
for every request through that alias. async_pre_routing_hook swaps
`model` from the alias name to the selected tier/route's model before
the deployment lookup runs, so the outbound call only ever merged in
the tier deployment's own litellm_params, never the alias's. Register
non-routing-config litellm_params from the alias deployment and apply
them to the request whenever a pre-routing hook substitutes the model.

* fix: satisfy ruff-strict-budget UP006 and router coverage checker

Use builtin dict[...] generics instead of typing.Dict for the two new
annotations introduced in the previous commit, since they pushed
UP006 over the codebase ceiling in ruff-strict-budget.json. Add a
direct unit test for _register_pre_routing_alias_overrides so the
text-based router_code_coverage.py checker sees it exercised by name.

* fix(router): replace alias-param denylist with a tight allowlist

_PRE_ROUTING_ALIAS_RESERVED_PARAMS excluded router-init-only keys from
the alias's litellm_params before forwarding the rest as request
kwargs, but GenericLiteLLMParams also holds deployment-management
fields (tpm, rpm, weight, tags, max_budget, budget_duration,
use_in_pass_through, litellm_credential_name, ...) on the same object.
Any of those left off the denylist would get silently forwarded as if
they were request kwargs.

Replace the denylist with a tight allowlist of exactly the two
request-shaping params this feature exists for - drop_params and
cache_control_injection_points - so unrelated management fields never
reach the outbound call regardless of what else GenericLiteLLMParams
grows to hold.

* fix(router): re-register adaptive-alias overrides on set_model_list reload

set_model_list() unconditionally clears pre_routing_alias_overrides on
every call (e.g. /config/reload), but _finalize_adaptive_router_if_configured()
skips rebuilding an AdaptiveRouter whose model_name already exists in
self.adaptive_routers - so _register_pre_routing_alias_overrides() never
ran again for an auto_router/adaptive_router alias after a reload,
silently dropping its drop_params/cache_control_injection_points.

Build the Deployment unconditionally and re-register its overrides even
on the skip-existing-router path; only the (expensive) AdaptiveRouter
construction itself stays skipped.

* style: ruff format after merging litellm_internal_staging

* fix(router): drop the alias-param allowlist, exclude only model

Per review discussion: instead of a router.py-local allowlist of exactly
which litellm_params an alias (auto_router/complexity_router,
adaptive_router, quality_router, semantic auto_router) can forward to
the request it routes, _register_pre_routing_alias_overrides now
forwards everything except `model` (the alias marker itself, e.g.
auto_router/complexity_router, never a real provider model).

Router-init-only fields (complexity_router_config,
complexity_router_default_model, auto_router_config,
auto_router_config_path, auto_router_default_model,
auto_router_embedding_model, adaptive_router_config,
adaptive_router_default_model, quality_router_config,
quality_router_default_model) now flow into request_kwargs unfiltered
too. That's safe because litellm.completion()/acompletion() already
strips anything in litellm.types.utils.all_litellm_params before
building the provider request - added these 10 keys there, alongside
the deployment-management fields (tpm, rpm, weight, ...) already listed.
Verified live: without that addition, complexity_router_config lands in
extra_body and ships raw to the provider; with it, it's stripped.

This moves the "which fields aren't real LLM params" list from a
router.py-local allowlist to the single existing global list every
completion() call already depends on, instead of maintaining two.

* refactor(router): look up alias litellm_params on demand instead of caching them

_register_pre_routing_alias_overrides cached each alias's litellm_params
into self.pre_routing_alias_overrides at deployment-init time, which
required keeping that cache in sync with set_model_list() reloads - the
exact bug the previous adaptive-router-reload fix was patching around
(AdaptiveRouter survives a reload, but the cache didn't always get
refreshed to match).

Delete the cache and the registration method entirely. async_pre_routing_hook
now looks up the alias's own litellm_params directly from self.model_list
via self.model_name_to_deployment_indices at request time, the same
model_list that's already correctly rebuilt on every set_model_list()
call. No second piece of state to invalidate, so the reload staleness
bug class isn't possible anymore, and it's less code than before.

* fix(mcp): keep out-of-contract upstream error bodies out of client responses

The token and DCR relays serve unauthenticated OAuth clients, so only the RFC 6749/7591 error fields may cross the trust boundary. A rejection body outside those contracts (HTML error page, proxy banner, stack trace) is now logged server-side, bounded, and the client response names only the upstream status. Addresses the Veria information-exposure finding

* fix(mcp): re-request the sealed scope on a bridge refresh when the client omits it

The refresh envelope seals the upstream scope as the scope to re-request (RefreshCredential), but _prepare_bridge_refresh dropped it, unwrapping only the refresh token, and the exchange added scope to the upstream request only from the client's HTTP form. A DCR/MCP client typically omits scope on refresh, so the sealed scope was never sent and a stricter upstream could narrow or drop the renewed token's scope

Thread the sealed scope through _BridgeRefreshReady.upstream_scope and fall back to it when the client sends none; a client-supplied scope still wins, which RFC 6749 section 6 bounds to the original grant. The regression test drives a refresh where the client omits scope and asserts the upstream POST carries the sealed scope, mutation-checked against both the drop and the fallback

* fix(ui): render the sidebar scrollbar with shadcn ScrollArea (#33124)

* fix(ui): render the sidebar scrollbar with shadcn ScrollArea

The sidebar navigation scrolled through a native overflow-y-auto container, so the browser drew its default scrollbar. It now scrolls through the shadcn ScrollArea primitive so the thumb matches the rest of the dashboard

Switching to ScrollArea surfaced a latent styling gap. The Base UI scroll-area, tabs, and separator primitives rely on data-horizontal and data-vertical Tailwind variants that resolve to [data-orientation="horizontal"] and [data-orientation="vertical"], and those variants ship in shadcn's shared stylesheet. The project never imported it, so the classes matched nothing and the scrollbar collapsed to zero width. This adds shadcn as a devDependency and imports shadcn/tailwind.css, which also repairs the vertical tabs and separator styling. See shadcn-ui/ui#9196 for the upstream tracking issue

* refactor(ui): inline the Base UI data-* variants, drop the shadcn dep

The earlier fix imported shadcn/tailwind.css through the shadcn devDependency, which pulled 219 packages and tied the CSS build to shadcn's package exports (an open Turbopack-breaking bug, shadcn-ui/ui#10931). shadcn's model is that we own the components, so the custom variants those components depend on belong in our own stylesheet rather than a runtime dependency. This inlines the nine data-* custom variants and the no-scrollbar utility that the Base UI primitives reference into globals.css, and removes the shadcn package.

* fix(mcp): carry the requested scope forward when the upstream omits it on a bridge refresh

The prior fix sent the sealed scope on a refresh, but the re-minted refresh envelope re-seals scope from the upstream response, and RFC 6749 section 5.1 lets an upstream omit scope when it is unchanged. So after one refresh whose response omitted scope, the new envelope sealed scope=None and every subsequent refresh dropped it, letting a stricter upstream narrow the renewed token

When the upstream omits scope on a bridge refresh, seal the scope we requested (which RFC 6749 section 5.1 defines as the granted scope when omitted) into the renewed access and refresh envelopes, so the scope survives the whole refresh chain. The regression test refreshes against an upstream that omits scope, asserts the new refresh envelope still carries it, and refreshes again off that envelope to prove the chain does not lose it, mutation-checked

* refactor(mcp): classify upstream OAuth faults once and derive status, code, and prose from the value

Replaces the accreted relay helpers with a faults package (types, classify, render_oauth): every
upstream token/DCR rejection is classified into exactly one fault value and the response status,
wire error code, and prose are all derived from that value, so a caller-fault code can never ship
on a server-fault status (the bugbot finding on invalid_grant over a 500). Classification takes the
credential source into account: invalid_client and friends against the server's stored credentials
are the operator's fault and render as 502 server_error with gateway-authored prose while the IdP's
prose stays in server logs; the same codes against caller-supplied credentials relay on the status
the code implies. Classifiers are total, so an unreadable rejection body (lying content-encoding,
unconsumed stream) yields the same 502 fault instead of resurrecting the opaque 500 (the second
bugbot finding); DCR rejections normalize to 400 per RFC 7591 regardless of the upstream's status

* style(mcp): unquote annotations and use PEP 604 unions in the faults package

* fix(mcp): detect upstream invalid_grant by the RFC 6749 error field, not a body substring

The bridge refresh path decided whether an upstream token-endpoint rejection was invalid_grant by substring-matching the raw response body, so a rejection whose actual error is something else but whose error_description merely contains the string invalid_grant would false-match, map to invalid_grant, and trigger a needless authorization_code re-run

Parse the RFC 6749 section 5.2 error object and compare the error field. A non-JSON body, or an error that is not invalid_grant, now propagates as the upstream error rather than being reinterpreted. The regression test drives an invalid_client rejection whose description contains the string invalid_grant and asserts it is not mapped, mutation-checked against the substring match

* fix(mcp): keep upstream self-blame codes and gateway capability gaps off the caller

Extends the fault matrix per review: server_error and temporarily_unavailable are codes by which the
upstream blames itself, so they classify as a new UpstreamReportedFault arm rendering 502/503 with a
matching wire code instead of a 400 that blames the caller; invalid_target is a gateway capability
gap (RFC 8707 resource indicators, LIT-4339) and is gateway-blamed regardless of whose credentials
were presented; the DCR classifier shares the same blame assignment. The gateway-fault arm is renamed
GatewayRejected since it now covers capability gaps as well as stored-credential rejections

* chore: add CODEOWNERS for ui and proxy UI build artifacts (#33131)

* feat(ui): rebuild the Teams table on the shared DataTable (#33128)

* feat(ui): rebuild the Teams table on the shared DataTable

The Your Teams tab moves off the Ant Design table onto the shared DataTable that the Virtual Keys page uses, following the new dashboard design. It gains server-side sort, pagination and filtering, a toolbar with a filter drawer and a columns menu, and a per-row actions menu

Sorting is wired only to the columns /v2/team/list can actually order by (team_alias, created_at); Spend / Budget and Updated stay unsorted because the endpoint silently ignores those fields. The design's "Created by" column is dropped since the team object has no such field, and the drawer's "Has keys" filter is dropped for the same reason. The Resources cell shows members, models and keys as colored pills, and the actions menu keeps the existing Edit, Copy team ID and Delete behaviors, with Edit and Delete gated to Admin

The teams grid gets its own unit tests in TeamsPage/TeamsTable.test.tsx. Teams.tsx keeps the create-team modal, delete modal, detail view and tabs, now refreshing the list through React Query invalidation instead of a manual refetch

* fix(ui): match Teams loading skeletons to the rendered row height

The default twoLine and chips skeleton shapes rendered the Team and Resources cells shorter than the loaded row (a real row measures 55px, the old skeleton ~49px), so the loading state looked visibly squat. Give the Team column a custom renderSkeleton that mirrors the two-line IdentityCell (measured 54px) and the Resources column one that mirrors the pills, and mark the hidden Rate Limits column as two-line so it matches when shown

* fix(ui): keep team admins' Members tab by deriving is_team_admin from the selected team

The redesign computed is_team_admin from useTeam(selectedTeamId), but that hook returns teamInfoCall's nested { team_info: { members_with_roles } } shape, so the top-level members_with_roles read was always undefined and is_team_admin was always false. For a non-proxy-admin team admin that hid the Members, Member Permissions and Settings tabs in the team detail view, which broke the team-admin add/remove member e2e tests. Pass the Team object up from the table instead (/v2/team/list returns it with a top-level members_with_roles), matching the pre-redesign behavior; proxy admins were unaffected because is_proxy_admin already granted access

Also point the Delete-a-team e2e at the new kebab: open the row actions menu, then click Delete team, rather than clicking the old inline delete icon

* fix(keys): persist key_type so the UI shows correct key scope instead of "All Proxy Models" (#33115)

* fix(ui): derive key model scope so SCIM/management/read-only keys stop showing 'All Proxy Models'

key_type is not persisted on a key (the proxy maps it to allowed_routes and
drops it), so the keys tables only inspected the models list and rendered
'All Proxy Models' for any key with an empty models array, including SCIM,
Management and Read-only keys that cannot call a single model.

Add deriveKeyModelScope(allowed_routes) and render 'No model access' with a
scope tooltip for those recognized scopes; unrestricted, AI-API and custom
keys keep the existing model-list rendering.

their type alongside the derived allowed_routes. Surface it on the key read
and create response models. The dashboard now prefers the persisted key_type
for the no-inference buckets and keeps the allowed_routes derivation as the
fallback for keys created before the column existed (key_type null), so no
backfill is required.

* feat(router): opt-in session affinity for complexity router (#33126)

* feat(router): opt-in session affinity for complexity router

Complexity router reclassified every turn, which could flip the routed
model group mid-session and break provider-side prompt caching. Add a
session_affinity config flag: when a session_id is resolvable, pin the
model chosen on the first turn and reuse it for the rest of the session,
skipping reclassification. Pinned turns still stamp the adaptive
bandit's chosen-model metadata so reward feedback keeps working when
adaptive=True.

* fix(router): refresh session-affinity TTL on hit, scope pin by API key

Two issues from review: the TTL was only set on the first classification,
so an active session outliving session_affinity_ttl_seconds silently lost
its pin instead of refreshing as documented. And the cache key was scoped
only by session_id, which is client-supplied and unauthenticated, so two
different callers reusing the same session_id could poison each other's
routing pin. Refresh the TTL on every cache hit, and namespace the cache
key by the proxy-derived API key hash when available.

* test(e2e): otel trace completeness on /chat/completions (#33132)

* test(e2e): OTEL trace completeness on /chat/completions against a local Jaeger destination

Adds the logging-suite infrastructure for LIT-3787 trace-completeness coverage:
a jaeger service in the compose stack as the OTEL v2 destination (arize_phoenix
preset pointed at it via PHOENIX_COLLECTOR_HTTP_ENDPOINT, so gen-AI spans export
through a preset-owned provider - the code path where trace splits happen), a
typed Jaeger query read-back client, and the first test: one successful
non-streaming /chat/completions call exports ONE complete trace (root SERVER
span + auth/db/cost children + gen-AI CLIENT span, no dangling parents).

* test(e2e): harden the otel trace read-back per review

Jaeger reads now query server-side by the litellm.call_id span tag instead of
paging recent traces and filtering client-side; the compose stack's background
jobs alone can push a request trace past the page. A failed query hard-fails
instead of reading as an empty result, the settle predicate now also waits for
the prefix-matched db span the assertion demands, parent-chain walking follows
CHILD_OF references only, the zero-trace and split-trace failures get distinct
messages, jaeger gets a healthcheck so the depends_on condition is accurate,
and the chat docstring names the route the code actually asserts

* test(e2e): author the chat trace test docstring

* Update logging section in CLAUDE.md

Removed mention of OTEL trace-tree completeness from logging integration section.

* fix(sso): paginate through all pages when fetching service principal group assignments (#33149)

get_group_ids_from_service_principal only read the first page of the
Graph API appRoleAssignedTo response, so tenants with more than 100
groups assigned to the enterprise application silently lost group
memberships during SSO login. Loop over @odata.nextLink with the same
MAX_GRAPH_API_PAGES cap that get_user_groups_from_graph_api already
uses, and warn when the cap is hit.

* test(e2e): otel trace completeness on /v1/messages (#33133)

* test(e2e): OTEL trace completeness on /v1/messages

Extends the LIT-3787 trace-completeness suite to the Anthropic-native route:
one successful non-streaming /v1/messages call must land at the destination as
ONE connected trace (root SERVER span + auth/db/cost children + gen-AI CLIENT
span, no dangling parents). Adds the raw /v1/messages sender to the logging
suite client.

* test(e2e): reuse the shared AnthropicMessagesBody per review

Drops the duplicate /v1/messages request model in favor of the one models.py
already provides (budget_client uses the same one), passes max_tokens at the
call site to match the sibling chat test, notes in the docstring why the
gen-AI span is named chat on this surface, and adopts the hardened read-back
signature

route: one successful non-streaming /v1/responses call must land at the

CHEAP_OPENAI_MODEL config constant, and registers responses in the otel
registry cell's exercised_on.

* feat(ui): add adaptive routing settings to Auto-Router v2 (#33146)

* refactor(mcp): extract the dcr_bridge token flow into bridge_token_flow.py

discoverable_endpoints.py had grown to 2695 lines mixing FastAPI route handlers with the dcr_bridge token-flow logic, against the no-monster-files convention. This moves the bridge token flow (the litellm-key/user resolution, the SCIM revalidation gate, and the mint/refresh envelope logic with their types and error mappers) into a dedicated bridge_token_flow.py, leaving the route handlers and the shared exchange_token_with_server orchestrator in discoverable_endpoints.py importing from it

Pure relocation, zero behavior change. The moved code is byte-verbatim except one type annotation quoted as a forward reference (_BridgeAuthorizationCode is used only for typing and imported under TYPE_CHECKING to avoid a cycle), and the new module imports nothing from discoverable_endpoints at runtime. 275 tests pass unchanged; the test patch targets for moved internals were repointed to the new module and verified to still apply

* bump: litellm-enterprise 0.1.49 -> 0.1.50, litellm-proxy-extras 0.4.76 -> 0.4.77, litellm 1.93.0 -> 1.94.0 (#33229)

* chore(deps): pin httplib2 and setuptools transitive floors (#33233)

Raise the constraint floors for two transitive dependencies so resolution moves them to their latest maintenance releases: httplib2 0.31.2 -> 0.32.0 and setuptools 82.0.1 -> 83.0.0. Both are pulled in only by optional integrations (Google API client, grpc tooling, lunary observability, the nvidia-riva extra), all lower-bound only, so the floors stay inside every requirer's allowed range and a default install is unaffected

* feat(ui): left-anchor the Create Key and Create Team CTAs (#33248)

Move the Create New Key and Create Team buttons out of the page header's
right-side action slot. On Teams the button now sits in the tab bar's left
slot, separated from the three tabs by a vertical rule, so the CTA and tabs
read as one left-anchored cluster. On Keys, which has no tabs, the button
anchors left on its own row beneath the title.

* fix(anthropic/passthrough): drop incompatible temperature when downgrading adaptive thinking for pre-4.6 models

Narrow the fix to the temperature reconciliation; the reasoning_effort
budget cap is reverted because the live translation grid relies on
budget_tokens >= max_tokens to reject unsupported effort tiers
(xhigh/max) on budget-mode models, so capping turned those 400s into
200s.

User budget was skipped when the key belonged to a team, letting

Remove the team_object guard in _user_max_budget_check so user
budgets are always enforced. Add skip_user_budget_on_team_key

Extends the read-time fix so the optimistic budget reservation also reserves the user spend counter for team-scoped keys, register skip_user_budget_on_team_key in ConfigGeneralSettings so /config/field/update accepts it, and surface it as a Boolean toggle on the Admin UI General Settings table via allowed_args in /config/list.

* fix(e2e): bound spend-log snapshots to a /spend/logs/v2 window (#33265)

The rate-limited batch spend test snapshotted unattributed rows via the
unpaginated /spend/logs whole-table read, which grows with the environment
(58MB on stage) and OOMKilled the e2e runner at its 512Mi limit on every

explicit date window instead, and SpendLogsParams now rejects a filterless

* fix(auth): scope the JWT enterprise gate to actual JWTs (#33296)

With enable_jwt_auth enabled but no enterprise license (premium_user
False), the JWT premium check fired on every request before the token
was inspected, so the master key, sk- virtual keys, and the encrypted
CLI/UI SSO session token that `lite login` issues all 401'd with "JWT
Auth is an enterprise only feature" and were never decoded. That broke
`lite login`, `lite claude`, and the proxy master key on any deployment
that turned JWT auth on without a license.

Move the premium check inside the is_jwt branch so it gates only real
JWTs. Non-JWT credentials fall through to their own auth paths
regardless of license; actual JWTs still require premium, so the
enterprise gate is unchanged for the feature it protects.

* refactor(ui): migrate guardrails table onto shared DataTable (#33303)

* feat(ui): migrate guardrails table onto shared DataTable

Move the guardrails list onto the shared DataTable + cell library as the
proof-of-concept for the simple-tables design migration, following the Teams
reference pattern.

Split the table into a thin container (guardrail_table.tsx) and column defs
(guardrailTableColumns.tsx): client-side sort defaulting to created_at desc, a
search + refresh toolbar, IdCell / DateCell / StatusBadge cells, real provider
logos, a rich empty state, and skeleton loading rows. Row actions move into a
per-row overflow menu; deletion stays disabled for config-file guardrails, now
surfaced as a disabled menu item instead of a greyed trash icon. Detail view
and the delete modal remain owned by GuardrailsPanel.

Restyle the "Add New Guardrail" control to the shared Button + dropdown menu.

Update the regression tests for the menu-based actions and drop the now-stale
eslint suppression entry that the rewrite eliminated.

* fix(ui): match guardrails table to the design

Address design-review feedback on the guardrails migration:

- Drop the search + refresh toolbar. The original table had neither and the
  SimpleTable design has no toolbar; the container now just renders the sorted
  table and its empty state.
- Give the Guardrail ID cell the design's hover affordance by rendering it with
  the shared IdentityCell (monospace, chevron on hover) instead of the blue
  IdCell pill.
- Stop pinning the actions column. Pinning added a sticky divider that the
  design and the Teams table don't have; it is now a plain right-aligned menu
  column, matching Teams.

* fix(ui): match loading skeleton row height to loaded rows

The compact skeleton row did not carry the h-8 height that real compact
rows get, so loading rows rendered shorter than loaded ones and the table
height jumped when data arrived. Mirror the same size-based height on the
skeleton row in the shared DataTable so every compact table loads at a
stable height

* test(ui): drop stale onGuardrailUpdated from guardrails table baseProps

The prop was removed from GuardrailTableProps when the toolbar went away;
the test baseProps still listed it. Harmless at the call site since it is
spread rather than an object literal, but dead and worth removing

* fix(ui): remove dead edit_guardrail_form after guardrails migration

The guardrails table migration dropped the last import of EditGuardrailForm,
which knip flags as an unused file. The form was already unreachable before
the migration: the table wired a delete button only, and nothing ever called
handleEditClick to open the modal, so the import was the sole thing keeping
the file referenced. Delete it and prune its now-stale eslint suppression
entry. Guardrail editing is unchanged and lives in the detail view

* fix(guardrails): four correctness fixes for incremental_diff streaming path

Four bug fixes on top of the OSS PR's incremental_diff streaming text
transformation, all inside the incremental_diff code paths only. No
existing block_only, non-streaming, or pre_call behavior is touched.

Fix #1 — Mixed content+tool_call finish_reason ordering
  _tool_call_passthrough_chunk now takes an optional finish_reason_per_choice
  map. For a choice carrying both delta.content and delta.tool_calls,
  finish_reason is stripped from the passthrough and recorded on the map so
  the final synthetic text chunk delivers it. Without this, SSE-compliant
  clients stopping at finish_reason drop the guardrailed text — defeating
  the redaction the whole feature exists for. (Greptile P1 twice, Veria.)

Fix #2 — Choice index sort in _process_streaming_transform
  indices/texts_to_check were derived from dict insertion order. For n>1
  streams where choice 1 emits before choice 0, guardrail-returned texts
  aligned to the input order mapped back to the wrong choice indices on
  write-back — wrong text goes to wrong choice. Sort raw_by_index.keys()
  up front so realignment is deterministic. (Bugbot Medium.)

Fix #3 — Cross-chunk pre-tool-call text flush
  With default streaming_sampling_rate=5, text chunks followed by a pure
  tool-call chunk carrying finish_reason='tool_calls' would emit the
  passthrough with finish_reason before any transformed text delta had
  fired. Same failure mode as fix #1 but cross-chunk. Now we flush any
  accumulated text via _round(is_final=False) BEFORE yielding the
  tool-call passthrough. (Greptile P1.)

Fix #4 — Terminator chunk for deferred finish_reason on empty mutated_text
  _build_transform_chunk returned None early when mutated_text_per_choice
  was empty. If a mixed content+tool_call chunk had deferred its
  finish_reason (via fix #1) and the guardrail then suppressed the text
  (empty return), the deferred finish_reason was never delivered. Now on
  is_final=True with empty mutated_text_per_choice, we emit a terminator
  carrying finish_reason per choice from finish_reason_per_choice.
  (Bugbot High.)

Also normalized Optional[X] → X | None across the OSS PR's added surface
via ruff UP045 autofix to keep the strict-rule gate within budget. Pure
mechanical typing style change, no semantic effect.

Regression tests for all four fixes:
- test_mixed_chunk_finish_reason_arrives_after_transformed_text (#1)
- test_text_flush_precedes_tool_call_passthrough (#3)
- test_final_finish_reason_flushed_when_guardrail_suppresses_text (#4)
- test_transform_sends_texts_sorted_by_choice_index (#2)

All fixes reachable only when streaming_transform_mode == 'incremental_diff'
is configured (via _run_incremental_transform_stream) or when a
StreamTransformSink is present (via _process_streaming_transform). Verified
scope-clean: no changes to block_only, non-streaming, pre_call, moderation,
or sibling guardrails.
