Move the WARNING that carries the internal denial detail out of the message formatter and into the auth exception handler. The denial exceptions now carry internal_message so access-group probes and fallback paths that catch and recover from the denial no longer log a false denial for an allowed request

Add litellm_settings.model_access_denied_message, a template ({model} placeholder) returned to clients instead of the detailed "can only access models=[...]" text on key/team/user/org/project and team-member model access denials. The full denial reason is still written to the proxy logs at WARNING. Unset keeps the existing detailed message, status codes and error types are unchanged.
Expose the new setting and the existing expose_router_debug_in_errors flag in the Admin UI general settings (String editor, Boolean toggle with an explicit True default) and allow both as safe DB overrides so they persist and propagate across workers.

_organization_max_budget_check returned early whenever org_max_budget
was <= 0, so an organization with an explicit max_budget of 0 was
treated as unlimited instead of zero allowance. Key, team, and user
budget checks already skip only on None; align organization budgets
with that convention.
validate_team_org_change had the same defect in a different shape: it
used a truthy check on the org's max_budget when validating a team
move, so an explicit 0 there silently skipped the guard too.

Move the cache-miss marker out of litellm.constants into auth_checks (CodeQL cyclic import) and stop
logging user_id/team_id in the lookup failure (CodeQL log injection).
Write the membership row through DualCache synchronously again instead of a background Redis task
guarded by a bounded write-epoch map: the epoch was sampled after the Prisma read, so an invalidate
that raced the read could be cached as current, and eviction of the epoch entry could let an old
Redis write land. The synchronous write keeps invalidate_team_member_spend_state authoritative.
Lookup failures return None again (fail-open like main) instead of 503, and the load is skipped on
routes that neither resolve a model nor run budget checks.

* perf(auth): prefetch user, team, membership, org and project in one MGET, one query and one pipeline
Auth read each object with its own Redis GET and, on a miss, its own DB
query, then the admission spend counters with one GET each. The prefetch
warms every entry the checks read with one MGET, one raw query for the
Redis misses and one pipeline write, and a per-request batch serves the
spend counter reads from one MGET. The per-object getters stay the

* perf(proxy): batch post-call spend counter reads and carry budget state through the request
Post-call warm checks, reservation reads and reconcile reads for one request now go through a task-local spend counter batch: one MGET answers every counter, successful increments write their result back into the batch so no second Redis read follows, and invalidation forgets the key. RedisCache.async_increment sends INCRBYFLOAT and its TTL command in one pipeline round trip.
Auth pins frozen team, user and org budget snapshots on UserAPIKeyAuth, the pre-call setup writes them into the request metadata, and Prometheus reads them back instead of calling get_key_object, get_team_object, get_user_object and get_org_object on the response path. The getters stay as the fallback for requests that carried nothing (custom auth, unauthenticated routes, skipped checks).

* perf(proxy): reconcile the budget reservation and the post-call warm checks from one MGET and one pipeline
A scope opened inside an open spend counter batch binds into it instead of starting its own, so the reservation reconcile and the post-call warm checks share the request's single MGET. The reconcile reads every reserved counter concurrently, sends the consistent adjustments in one INCRBYFLOAT+EXPIRE pipeline and settles a flushed or reseeded counter on its own afterwards, keeping the pre-call resize fail-closed. PendingSpendIncrement moves to spend_counter_batch so budget_reservation can build a pipeline without importing a private name

The session-token grant refresh reads get_team_membership on every request. A
member with no LiteLLM_TeamMembership row (the common lite-login case) returned
None without caching, so every request re-queried the DB and defeated the auth
cache. Cache the miss under a plain-string sentinel with the management-object
TTL, mirroring the MCP no-permission sentinel. All three readers of the key
already treat a non-model value as no row, and team_member_update already evicts
it, so a newly-created per-member budget is picked up on the next request.
* fix(proxy): bound concurrent key and spend-counter DB lookups to stop prisma pool thrash
A cache-miss burst fanned every get_key_object DB fallback and SpendCounterReseed
point lookup into the prisma query-engine httpx pool at once. httpcore's request
assignment is O(queued x connections) per event, so the event loop spent most of its
time in pool bookkeeping and the logging worker's 20s wait_for tripped. Callers now
wait on a small shared semaphore (PROXY_DB_LOOKUP_MAX_CONCURRENCY, default 25)
instead of queueing inside httpcore

Team reads on the auth path never loaded the team's alias table, and the
team-based JWT branch copied a hand-picked subset of team fields onto
UserAPIKeyAuth, so aliases (and a few other team grants) never reached JWT
callers: restricted teams 403'd alias requests and open teams 400'd them
Load the alias relation where the team row is read and cached, project the
team onto every team_* token field through one shared team_grants helper
used by both JWT returns, and keep the relation when team model add/delete
rewrites the cached team. ui_sso reuses the shared alias table model

* fix(logging): redact credential query params from the uvicorn access log
Raw virtual keys reached container stdout two ways:
- `GET /key/info?key=sk-...`, `/global/spend/report?api_key=sk-...`,
`/key/spend/report`, `/spend/logs`, `/user/daily/activity` and the Gemini
passthrough routes all put the credential in the request target, and
`uvicorn.access` had no redaction filter (only `uvicorn.error` did).
- the key budget error interpolates `LiteLLM_VerificationToken.key_name`,
a column with no enforced shape, into a message that is both logged and
returned to the caller.
`SecretRedactionFilter` cannot be reused on an access logger: it collapses the
record into `record.msg` and clears `record.args`, and uvicorn's AccessFormatter
unpacks those args at emit time, so every access line would raise TypeError.
`AccessLogRedactionFilter` scrubs the positional args in place instead.
An access line is the one input to the secret regex an unauthenticated caller
controls end to end, so two bounds go with it. The request target is cut back to
a whole query parameter under 512 characters before it is scanned, since a half
parameter is too short to match its own pattern and would be logged raw, and the
dropped tail is not logged at all. The connection-string pattern is bounded too,
because its user half could previously re-scan the rest of the string from every
`://`: a 16 KB URL of `a://` pairs took 314s and now takes 0.12s, with the caps
set high enough that an RDS IAM auth token used as a DSN password still redacts.
Credential query params are terminated by `&` like the existing `key=` and
`sig=` patterns, so redacting one param no longer swallows the rest of the
request line, and a second credential in the same query string is now redacted
on its own instead of surviving once the first one stops the span. `key_name` is
echoed into the budget error only when it still has the masked `sk-...abcd`
shape `abbreviate_api_key` writes, so a value put there by a direct DB write or
a migration falls back to the key alias.
Also point the `/key/info` and spend-report examples at the sha256 hash both
endpoints already accept, so callers stop putting raw keys in URLs that
third-party access logs record.
Resolves LIT-5909
* test(logging): assert on emitted access lines instead of filter registration
The two registration tests checked that an AccessLogRedactionFilter instance
sits in uvicorn.access.filters, which is the shape of the code rather than its
behavior. Handing the logger a real access record and reading what a handler
wrote covers the same wiring and still fails when the registration is removed.
* fix(logging): redact percent-encoded credentials from access logs
?k%65y=sk%2D... is a working credential once the request parser decodes it,
but the redaction patterns match literal text and never see it. Decode the
request target as a detector and drop the query when decoding reveals a
secret. The decoded text is never logged back, so a %0A cannot forge a
following log line
Also accept any four non-space characters in the masked key_name check, since
abbreviate_api_key copies the last four characters of a custom key verbatim
and those can be punctuation or non-ASCII
* fix(auth): keep control codes out of the masked key label
/key/generate accepts a custom key ending in an escape sequence, and
abbreviate_api_key copies those four characters into key_name verbatim, so
the over-budget message carried them to a terminal and a log viewer. Bar
whitespace and C0/C1 control codes from the four, and keep everything else
`_delete_cache_key_object` awaited the Redis delete unguarded, so any cache
backend error surfaced as a failure on an operation that had already been
committed. A Redis ACL that denies DEL on LiteLLM's unprefixed token-hash keys
turned a persisted `/key/update` into `400 Authentication Error, No permissions
to access a key`, and `/key/block` and `/key/regenerate` into 500s
Make the helper best-effort, the way `delete_cache_team_object` and
`delete_cache_key_objects` on either side of it already are: log the failure and
carry on. Nothing ends up staler for it, since the in-memory entry is dropped
before the Redis round trip and the write has already committed, so raising only
misreported a success
* fix(proxy): reset a stuck team member's budget
A per-team-member budget check reads a cross-pod spend counter that
nothing ever invalidates. Once a member exceeds their per-member
budget, resetting the key's spend, raising the user's or the team's
own budget, or issuing a new key all leave the member stuck, because
none of them touch this counter or its cached membership object.
Add POST /team/{team_id}/member/{user_id}/reset_spend to reset a
member's tracked spend, and invalidate the same cached state from
/team/member_update when it raises a member's own budget, so that
path also takes effect immediately instead of waiting on the
membership cache's TTL. Name the entity in the check's error message
so a stuck member is diagnosable from the 429 body alone.

When get_team_object fails, the centralized auth gate rebuilds the team
from the token's own fields. A token whose team row was missing when the
key was read carries team_models=[] and team_blocked=False, and the
model-access check reads an empty model list as every model, so the
rebuilt team grants more than the real team ever did.
get_team_object reported a deleted team and a database that would not
answer as the same 404, so the fallback could not tell a definitive
answer from a degraded read. Raise a TeamNotFoundError subclass, still a
404 with the same detail so every other caller is unaffected, only when
the database answers and the row is absent.
A team that is provably gone now refuses, and no setting overrides that.
Otherwise the grant is merely unknown: a token carrying one may vouch,
since replaying a recorded grant cannot widen it, and a token carrying
none may not. allow_requests_on_db_unavailable still opts back out there,
and is only consulted once the failure is known to be a degraded read.
The Admin UI mints every session key against the UI_TEAM_ID sentinel,
which by design never has a team row, so every UI request hit the new
refusal with no override. Exempt UI_TEAM_ID explicitly so it keeps
reconstructing from the token unconditionally, matching how the MCP
handler and agent_permission_handler already special-case it.

* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
`pytest.raises(Exception)` with no `match=` passes on any error that broad. A
TypeError from a refactor, a botched fixture, an import that moved: all of them
read as the rejection the test claims to police, so the test goes green for the
wrong reason and stays green after the behaviour it guards is gone.
PT011 closes that gap for the 317 sites B017 could not reach, because B017 only
fires on a single-statement body with no `as e` binding. Each pattern here is the
message the code actually raised, recorded by running the sites under a plugin
that logged the concrete type and text per call site, so the assertions describe
observed behaviour rather than a guess. Where a site raises more than one message
across its parametrize cases, the pattern is an alternation of what was seen;
where the exception carries an empty `str()` and puts the text on `.message`, the
site keeps a narrow `noqa` with the reason.
PT014 removes four parametrize cases that were listed twice. The duplicate re-runs
an assertion that already passed, and it usually marks a case someone meant to
vary and forgot to edit.
team_allowed_routes and admin_allowed_routes only matched exact strings or named route groups, so a whole prefix of pass-through endpoints had to be listed route by route in config. Match trailing-wildcard patterns with the same helper the key-level allowed_routes check uses, so "/prefix/*" covers endpoints registered later.

A request can name more than one model, through a comma-separated model or target_model_names on
the batch and fine-tuning routes, and the gate only looked at the string case, so an unpriced model
riding alongside a priced one went through and billed. Check every candidate and name the unpriced
ones in the 403
Aliases had the same problem on the other side: a group that prices itself through its model_info
block lands in the cost map under its deployment id, and the explicit-cost check walked the raw
model list by group name, so an alias pointing at that group read as unpriced. Resolve the group
through the router the way the pricing check already does
Also correct the 403 copy. Providers that return their own usage cost still bill for these models,
so the accurate claim is that litellm has no pricing of its own for them
A deployment that overrides any cost_per field, including at zero, now counts as priced so it is not blocked as unpriced
