A mixed /team/member_add list that names an existing member used to run
add_new_member for them, which created or cloned a budget that the empty
upsert update branch never linked to their membership row. Filter the
requested members against the freshly locked roster first so budgets and
membership rows are only written for members who are actually new

Replaces the per team advisory lock and Pydantic roster parse in the spend flush
with a single INSERT ... ON CONFLICT statement that checks the stored roster in
SQL, so malformed roster JSON cannot fail the whole flush and large batches no
longer issue two queries per team inside the fixed transaction deadline

Take the team advisory lock in the spend flush transaction and read the roster
through it, so a delayed flush after /team/member_delete cannot recreate the
deleted LiteLLM_TeamMembership row. TEAM_ADVISORY_LOCK_SQL moves to
team_repository so the spend writer can import it without a circular import
Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
add_new_member only wrote a LiteLLM_TeamMembership row when a budget id
resolved, and the spend writer used update_many so a missing row failed
silently. Members without a budget therefore never accrued per-member spend.
The membership row is now always upserted (budget_id NULL when no budget
applies) and the spend write is an upsert so members added before this fix
start accruing on their next request.

* feat(proxy): limit repeated failed Admin UI sign-in attempts
The Admin UI sign-in endpoints accept an unbounded number of password attempts.
All three call authenticate_user, and none of them keeps any record of how many
times a given caller has already been refused, so a misbehaving or misconfigured
client can retry indefinitely at full speed.
A LoginThrottle is now a required argument to authenticate_user, so the accounting
lives at the one function all three endpoints share and a fourth endpoint cannot be
added without deciding what to pass. Failures are counted per username and source
address over a fixed window and further attempts are refused with 429 and a
Retry-After header. The check runs before the database lookup and before the
password comparison, so a refused caller does no further work.
Only genuine credential rejections count. Configuration errors do not, a refused
attempt does not extend the window, and a successful sign-in clears the bucket.
The username is case folded because the user lookup is case insensitive, so casing
cannot multiply the allowance. Both credential rejections now return one identical
message. SSO is unaffected; it never calls this function.
max_failed_login_attempts (10) and failed_login_window_seconds (900) are read from
config.yaml, with LITELLM_DISABLE_LOGIN_RATE_LIMIT to turn the accounting off. They
are deliberately not database backed, so editing YAML always wins and an operator
refused by a bad value can recover.

* fix(proxy): write failed-login counters and their expiry in one Redis call
Use RedisCache.async_increment_with_floor (a single Lua INCRBY + EXPIRE) for the
shared login counters instead of the two-step INCRBYFLOAT then EXPIRE, so a
counter can never be committed to Redis without its expiry. The repair in
_remaining_window now only covers expiries stripped out of band (PERSIST, a
restore) and uses the same atomic call

* fix(proxy): resolve the login rate limit kill switch once per process
Reading LITELLM_DISABLE_LOGIN_RATE_LIMIT through get_secret_bool on every
unauthenticated sign-in attempt meant a hosted secret manager in read mode
was queried once per password guess, before any counter was checked

* fix(proxy): count failed sign-ins in Redis alone while it answers
Every worker spends one shared budget and a successful sign-in clears it for all
of them. This worker's own counter is only consulted while Redis raises, so an
outage degrades to per-worker accounting instead of switching the control off

* fix(proxy): keep counting the failed sign-ins Redis missed once it answers again
A guess is recorded in exactly one place, Redis or this worker's own store when Redis
refused it, so the count is the sum of the two. Redis is read through
async_batch_get_counts, which raises on failure, instead of async_get_cache, which
swallows it into None and read as an empty counter

redis_usage_cache explicitly; behavior is unchanged.

* feat(proxy): throttle failed Admin UI sign-ins per source and source/username
Replace the username-global lockout with counters keyed by source address and by
source/username pair. Each has a fixed counting window (60s) and a separate
block TTL (300s). Blocks are soft: a correct password still signs in, wrong
passwords from a blocked key take one of 5 held slots per worker and are held
30s before a 429. Once a pair is blocked its failures stop counting against the
source. The source scope runs only when trusted_proxy_ranges is set, IPv6 is
grouped by /64, and per-source limits accept IP and CIDR overrides with
longest-prefix matching. Redis is authoritative through one Lua script per
failure, with bounded per-worker fallback when Redis raises.

* fix(proxy): keep the sign-in hold pool from refusing a correct password
The held-attempt cap ran before the password check, so five parked wrong

pool-full refusal carries the block's remaining time as Retry-After

* feat(proxy): hard-block throttled Admin UI sign-ins with no credential bypass
A blocked source, or source and username pair, is now refused with 429 before the database lookup and password check, in place of the soft block that held wrong guesses for 30 seconds and let a correct password through. The env admin credentials and the master key typed into the login form are refused like any other credential while blocked; recovery is the master key as an API bearer token, which never goes through the sign-in path
trusted_proxy_ranges: [] now means clients connect directly, so the peer address is the source and the per-source limit stays on. Only an unset or malformed value leaves the topology unknown, warns at startup and turns the per-source limit off

A merge on this branch dropped the ^ anchor and MULTILINE flag from the
doc_key_pattern, so the unanchored match started swallowing key names
into captured fields whenever a row's description cell itself contains
a pipe (Literal unions and similar). The check then reported 27
long-documented keys as undocumented. Restores the exact pattern used
on main, verified against a live litellm-docs checkout: all 58 Router
init params resolve as documented.

MutableMapping.clear pops items until the mapping is empty, but __delitem__
keeps config-owned keys, so clear spun forever on any store that had loaded a
config file. unittest.mock.patch.dict calls clear on exit, which is why the
proxy-infra and proxy-endpoints shards hung at 99 percent until the 20 minute
job timeout on every run since the store started refusing config-owned writes

The two pass-through reload tests register real FastAPI routes on the
shared proxy app and only clean up the internal registry, so any test
running after them in the same worker sees stray /v1/kept-* and
/v1/deleted-* routes. test_component_allowlists counts those as
uncovered and fails. Snapshot app.routes and the registry up front and
restore both in a finally block.
