* test: count a zombie grandchild as gone in the migrate deploy timeout test
A SIGKILLed grandchild whose parent died in the same killpg reparents to
PID 1 or the nearest subreaper and stays a zombie until reaped, and signal 0
still succeeds on a zombie, so the timeout test read it as alive wherever
PID 1 is slow to reap or never does. The sibling test in
tests/test_litellm/proxy/db already handled that; both now share one
process_is_gone helper that reads the /proc state and reaps its own
children, with unit tests for the live, reaped, unreaped, and foreign
zombie shapes.

* test(proxy): make two proxy-infra tests independent of sibling-test state
Both tests read process-global state that another module in the same xdist
worker can change, so they passed or failed on shard scheduling rather than on
the behaviour they assert.
test_gateway_plus_backend_covers_full_app checked allowlist coverage against
the live route table. gateway/main.py trims routes once, inside the lifespan,
so it only ever sees what is registered at startup; a lazy feature appends its
router on demand afterwards and is never filtered. Those routes cannot be
dropped on the floor, but they do enter the assertion the moment a sibling test
warms the feature, and 110 of them sit in neither allowlist. Subtract exactly
the lazy features this process has loaded, which leaves the assertion at full
strength for every eagerly registered route.
test_real_proxy_child_auth_privacy_and_body_policy pins prisma_client to a bare
object(). litellm.max_budget is a module global that nothing restores between
tests; once a sibling leaves it above zero, user_api_key_auth takes the
global-spend branch, dereferences prisma_client.db, and the AttributeError
surfaces as HTTP 401. Pin max_budget next to the other globals the test already
controls.
* test(proxy): measure allowlist coverage in a pristine interpreter
The previous revision subtracted paths matching a loaded lazy feature's
prefixes. Those prefixes are broad enough to swallow eagerly registered routes:
31 of them, including /openai/deployments/*, /access_group/*, /cursor/* and
/mcp, which would have made a real allowlist regression invisible.
Run the coverage check in a fresh interpreter instead. No lazy feature is
loaded there, so the route table is exactly the one gateway/main.py's lifespan
trim sees, and nothing has to be subtracted for the result to be deterministic.
The probe also reports the lazy modules it loaded and its route count, so an
empty uncovered set cannot pass vacuously.
Drop _component_paths and the four allowlist constants it used; the probe
reproduces the predicate in the child process.
* feat(proxy): configurable key_alias_pattern for key generate, update, and regenerate
Adds litellm_settings.key_alias_pattern, a regex every key_alias sent to
/key/generate, /key/service-account/generate, /key/update, and
/key/{key}/regenerate has to fully match. A non-matching alias gets a 400
that names the setting and the pattern. When set, it replaces the built-in
rule enable_key_alias_format_validation turns on, and the baseline
unsafe-name check still runs first. An invalid regex fails config load.
* fix(proxy): cap key_alias length under key_alias_pattern and type the test fixtures
* style(proxy): declare key_alias_pattern with a PEP 604 union

* test(e2e): hold every worker under an idle RSS budget before any traffic
The harness reads /debug/memory/summary on every replica once at collection
time, right after the readiness gate and before this pytest process sends any
traffic, and the memory suite's first test fails when any worker idles past
E2E_MEMORY_IDLE_RSS_BUDGET_MB (768 MB by default) or gives no reading at all.
A v1.100.x worker with a database idled at 836-886 MB where v1.101.0rc1 idled
at 544 MB on the same database: prisma-client-py's default recursive type
depth generated 91k TypedDict classes that v1.101.0's recursive_type_depth = -1
cut to 19k. The budget starts at the rc1 reading plus headroom.
* test(e2e): read idle RSS only when the idle budget test is selected
Gate the collection-time /debug/memory/summary read on a selected test using
the idle_rss fixture and skip it under --collect-only, so sessions that never
run the idle budget test pay no round trip. Drop the markerless unit test file
the e2e guide bans and assert live that every configured replica was measured
* test(e2e): take the idle RSS read after collection settles
Read every replica's RSS from a tryfirst pytest_collection_finish hook so -k
and -m deselection has already run, and only when a selected test still asks
for the idle_rss fixture and the run is not --collect-only
* test(e2e): record the heaviest idle RSS reading as junit properties

Post-call GuardrailRaisedException failures kept their deployment labels on main but lost them
on this branch because every GuardrailRaisedException was treated as a pre-routing reject.
The proxy failure path now flags litellm_params with proxy_rejected_before_routing only when
it adds deployment attribution itself, and the Prometheus logger keys deployment selection
off that flag

* fix(proxy): key pre-routing reject flag off provider handoff, not caller metadata
Caller-supplied metadata.model_info (kept for keys allowed to override pricing) no longer
suppresses proxy_rejected_before_routing. The hook now checks the logging object's
first_api_call_start_time, which only the provider handoff sets, so Prometheus never
records a deployment failure for a request that was rejected before routing.

* fix(proxy): share model rate-limit buckets between a model_group_alias and its target
A request sent under a model_group_alias counted in its own per-key, per-team,
per-org, and per-project model bucket, so a key could double a deployment's
default_api_key_rpm_limit / tpm_limit by alternating the alias and the model
group name, and a metadata model_rpm_limit / model_tpm_limit keyed by the
model group never applied to alias requests. The limiter now resolves the
requested name to its model group before keying any model bucket, looks the
limit up by the requested name first and the model group second, and charges
post-call tokens to the same bucket.

* fix: enforce disable_custom_api_keys from general_settings
The gate in _check_custom_key_allowed read the persisted UI settings row
through get_ui_settings_cached, which had two consequences.
A config-file general_settings.disable_custom_api_keys was never enforced,
because the gate only ever looked at the stored ui_settings row. POST
/key/generate with a custom key value returned 200 even with the flag set
to true in config.yaml.
The read went through a DualCache with a 600s TTL, which is per worker
without Redis, and only the worker that served PATCH /update/ui_settings
refreshed it. A gate flipped through the UI was then a coin flip across
workers for up to ten minutes.
Both go away by routing the flag the way the other runtime UI flags are
already routed. Adding it to _RUNTIME_GENERAL_SETTINGS_FLAGS and to the
settings rules' _UI_SETTINGS_FIELDS makes SettingsStore resolve it from the
ui_settings row with the config file winning, and every pod re-reads it on
its own settings sync rather than holding a private cached copy. The two
lists have to stay in step: a flag in one and not the other resolves
against the wrong stored row and silently never reaches a reader, so there
is a test for that invariant.
Writes to the ui_settings table did not publish on the config-sync channel,
so other pods only discovered a change on their next periodic reload. Adding
litellm_uisettings to _CONFIG_SYNCED_TABLE_NAMES puts it on the same pubsub
path model and SSO config writes already use, which cuts cross-pod
propagation from tens of seconds to a few.
The value reaching the gate is run through coerce_bool first. Resolution
hands back the raw YAML value, so a quoted "true" in config.yaml is a str
and the old `is True` check let custom keys straight through.

* refactor(rust): align the cache crates with Python and activate every backend
The cache port had drifted: lifecycle and Redis-only operations sat on
`BaseCache`, counters were pinned to `f64`, each semantic backend defined its
own embedder and prompt handling, and only the in-memory backend could be
selected natively.
- Split `disconnect` and `test_connection` out of `BaseCache` into optional
capabilities, implemented only where the Python class defines them, and give
every Redis-only operation its own capability trait.
- Decouple counters from the stored value type, so one backend can serve both
responses and counters as Python's `RedisCache` does.
- Share one `Embedder` and prompt contract in `litellm_cache::semantic`, and
make the Redis and Valkey semantic backends generic over their codec.
- Port the Python operations that were missing: `async_refresh_ttl`,
`async_rpush_and_trim`, `async_set_cache_pipeline_with_ttls`, the DualCache
pipeline, sadd, bulk delete and TTL reads, and the semantic-similarity
write-back.
- Take the HTTP client from the host pool in the GCS, S3 and Azure backends.
- Activate all nine backends through the Rust catalog, whose rules all stay
`PYTHON_ONLY`, and route the `Cache` facade's storage calls to the native
runtime when one is selected.
- Give every crate the same layout, move all tests to `tests/` on rstest, and
add the shared `litellm-cache-testing` contract suite.
