A pip install ships the schema inside the package but no generated client, and
since v1.83.3 no startup path generates one, so the proxy cannot start with a
database. Startup now generates it from the shipped schema when it is missing,
with the venv's scripts dir on PATH, and the import error names the exact
command with the schema path.

* fix: keep updated_at moving on zero-spend budget resets
* fix: never leave spend below zero after a budget reset
* fix(proxy): keep the stored budget reset time when budget_duration is resent unchanged
Key, user, and team updates recomputed budget_reset_at whenever the body carried budget_duration, and the Admin UI key form sends it on every save. Under the guarded reset, a resend during a sweep skipped that period's reset, and a resend after the boundary skipped it on main too. An unchanged duration now keeps the stored reset time
* fix(proxy): keep a resent budget reset time only once it is due
A save that resends the same budget_duration keeps the stored reset time
only when that time has already passed, so the scheduled sweep still
resets the period it is due for. A row that is not due yet realigns its
reset time on save, the same as before.

* feat(budgets): add per-model tpm and rpm limit maps to budgets and customers
Budgets gain model_tpm_limit and model_rpm_limit (model name to whole number, 0 or more).
/budget/new, /budget/update, /budget/info and /customer/new carry them, and the auth
path loads a customer's maps onto UserAPIKeyAuth as end_user_model_tpm_limit and
end_user_model_rpm_limit so the limiter can enforce them in a follow-up.
* fix(budgets): keep org, team and project per-model limits in metadata; lock_timeout and type gate fixes
Organizations, teams and projects store model_tpm_limit / model_rpm_limit in their own metadata,
which the limiter reads, so the shared budget allowlist leaves those two fields to customers.
Migration starts with SET LOCAL lock_timeout. Mapping annotations and rebind-ok reasons satisfy
the type discipline gate. Customer info tests expect the two new budget keys.
* fix(organizations): keep stripping budget_id and flattening nested per-model maps on update
The update path pops every budget field from the organization row again, so a caller's budget_id
never changes the attached budget, and a nested litellm_budget_table still flattens the two maps
into org metadata. Drops the explanatory comment on CUSTOMER_ONLY_BUDGET_FIELDS.
* fix(types): keep basedpyright and ruff strict counts flat for the new budget fields
Reads the per-model maps off the end-user params with membership checks instead of .get on an
untyped dict, writes the inline customer budget through the client's typed jsonify_object, and
builds budget rows in handle_budget_for_entity with model_validate so the two Mapping fields never
receive object-typed kwargs.

* test: update the spend tests that still expected the pre-ledger accounting queues
#49872 made the SpendLogs ledger the default accounting path on purpose. A batch with no billable request now writes no cost row, a call the guardrail fails closed during a vendor outage keeps one spend row of either status while its key is still charged once, and charges left at a graceful shutdown are applied by the next start. The daily spend batch shutdown tests exercise the old queue, so they pin use_spend_logs_ledger to false.
* test(integration): price the guardrail relay model so the outage test can assert the charge
The relay model had no price, so every stream cost $0 and the outage test could not tell a charged call from an uncharged one. Both rigs now price it, and the test expects each served stream to cost 9 input and 4 output tokens and the key to be charged for all sixteen.
Also notes the skipped batch cost row case in the e2e rules file, next to the other explicit skips.
* test: repair four tests that fail for reasons outside the product
The OpenAPI docs gate test rebuilds the Rust extension with uv, and the integration lane blocks outbound traffic, so uv could not refresh its PyPI index for maturin. The test now runs uv offline against the cache the dependency install already filled.
The response cache test expected a chat reply blocked with empty content to be cached. Since #50057 a reply with no output is never cached, so that case now expects the repeat to reach the upstream and the real answer to be cached.
The Gemini cache hit e2e test gave the model 16 tokens, which its thinking can use up, and a reply with no text is not cached. It now allows 512 and checks the first reply has text.
The Together cache read e2e test picks the cheapest model with a cache read price. Since #50491 that is a -latest alias, whose target reports no cached tokens. Aliases are now left out of the pick.
* fix(complexity_router): user_turn continuations no longer replay an earlier ask's pin
A user_turn pin was stored per session, so when a new ask could not be
pinned (classifier timeout, housekeeping excluded) its tool continuations
replayed the previous ask's decision and could silently drop a hard task
to the cheap tier
Each pin now records a fingerprint of the ask that wrote it, and a
continuation ignores a pin from a different ask. A new ask that cannot be
pinned also overwrites the session pin with an empty one, which covers
continuations whose history lives server side (previous_response_id) and
carry no ask to fingerprint. Pins without a fingerprint keep replaying so
rolling deploys stay consistent
Fixes#44250
* fix(complexity_router): a new user_turn ask clears the previous ask's pin
Replace the per-ask fingerprint with a simpler rule. In user_turn mode every
new ask owns the session pin: a pinnable decision writes it as before, and
one that cannot be pinned clears it, so the ask's continuations classify
instead of replaying an earlier ask's model. This also covers continuations
whose history lives server side (previous_response_id)
Housekeeping calls never clear the pin. The check reads the classified
decision before the health, modality and cache gates, which rewrite the
cause of a failed-over title call
Fixes#44250
* fix(complexity_router): hold the default model for a user_turn ask whose classifier failed
Replace the clear-on-new-ask rule with a smaller change. In user_turn mode a
classifier failure now pins the default model for that ask, so its tool
continuations replay the default model instead of the previous ask's pin.
The next new ask classifies again, so the hold ends with the ask, and
session_affinity mode keeps never pinning a failed classification
Fixes#44250
* fix(complexity_router): a plan-mode request never replays a pin without a tier
A held default-model fallback has no tier when the default model sits
outside the tier pools, so replaying it skipped plan_mode_min_tier. A
plan-mode request now classifies instead of replaying a tier-less pin,
which is what it did before the fallback was held

* fix(proxy): give rag ingest managed file ids and team credentials on vector store file routes
RAG ingest through a team's OpenAI deployment now registers the uploaded file as a LiteLLM managed file and returns its managed id, so GET /v1/files lists it for the caller. Re-ingesting a managed id attaches the provider file and returns the caller's managed id
Model-less vector store file calls (create, list, retrieve, content, update, delete) from a team key now use the team's OpenAI deployment that ingest uploads through, via the router, and fall back to the direct path when the key may not use one. Explicit api_key, api_base, litellm_credential_name, and forwarded provider keys still win, and blank values count as absent
* fix(proxy): route managed vector store file ids to their team deployment and keep missing-file 404s off the router
Model-less team vector store file calls now go straight to the provider with the team deployment's
credentials, so 404s on missing files no longer put the team deployment in cooldown.
A managed file id on the vector store file routes now uses the deployment named by its
llm_output_file_model_id when that deployment is proxy-wide or belongs to the caller's team, and falls
back to target_model_names otherwise.
* fix(rag): keep managed ids and team checks on every file and search path
Ingest no longer registers a raw file id when file_url is empty, a managed
file id on a proxy without the managed files hook answers 400, and vector
store search and /v1/rag/query hits show the managed id ingest returned.
Model-less vector store file calls use the team deployment only after the
key, team, and member model checks pass, fall through to the router when the
team has no OpenAI deployment, and log the deployment they used.
* fix(rag): keep provider ids on lookup failures and mint managed ids only for keys that can use them
A database error while mapping search hits to managed ids keeps OpenAI's ids instead of failing a finished search. Ingest registers a managed id only when the caller passes the team deployment's model checks, so a model-limited key keeps the raw id it can still use, and the file routes share that check.
* fix(rag): attach the managed file copy that matches the ingest credentials
* fix(vector_store_files): route a managed file id to the caller team's copy
* fix(vector_store_files): keep the upload copy for a store registered with its own credentials
* fix(vector_store_files): use a managed file's team copy only when the store holds it
* fix(vector_store_files): attach a managed file's team copy and keep named credential options out of the store check
* fix(vector_store_files): attach the team copy only to a store that routes to the team deployment
* fix(vector_store_files): keep a managed store's routing and check the upload copy through its own deployment
* fix(vector_store_files): route a managed file to its upload deployment only when the key may call it
A managed file id names its upload deployment, and with require_managed_files off that id is not checked against an ownership record. The routes now use that deployment only when the caller may call its public model, else they keep target_model_names routing as on main.
* fix(vector_store_files): log a pinned managed file call under its deployment's public model name
* fix(vector_store_files): send a pinned managed file call's deployment key only to that deployment's base
* fix(vector_store_files): keep stored credential headers intact and fail the store check on errors other than 404
* fix(vector_store_files): answer a failed store check with the provider status and copy credentials read by name
* fix(vector_store_files): send a call to the upload copy when the store check fails without a 404
A store check error other than a 404 now leaves the call on the upload copy, the way main always routed it, so the real call keeps the router's retries, the provider's status, and its failure log instead of failing on one transient error
* fix(vector_store_files): keep a credential's no-log key out of the store check
A named credential carrying a no-log key made the store check call aretrieve with no-log twice, so every managed id call through that deployment answered 500 where main answered 200

* fix(router): count a Responses WebSocket turn's tokens before the next turn is admitted
* fix(responses): forward and log a finished websocket turn when its early count fails or is cancelled
A usage payload the parser rejects no longer stops the relay before the terminal event reaches the client, and a client that leaves while the turn is being counted still gets the turn logged. A cancelled early count now clears its counted-tokens marker so the logging callback counts the turn in full.
* fix(responses): finish a turn's early token count when the client leaves
A client that left while a finished turn was being counted cancelled the count halfway. The router's count could be written with no marker, so the logging callback counted the turn a second time. The count now runs to the end before the turn is logged, and the failure path goes back to clearing only on errors
* fix(router): count one router request per Responses WebSocket turn
A socket whose finished turns each counted their own request in router
usage no longer adds one more request when it closes, so N turns count N
requests, as N HTTP calls do. A socket with no counted turn still counts 1

* fix(proxy): say which empty-models rows keep access in 2.0.0
Teamless keys listing all-team-models get no models in 2.0.0, so the
boot warning no longer says every counted row keeps its access. It
names each upgrade outcome only when its kind is in use, says the counts
include blocked and expired rows, and words each kind by what the

* fix(proxy): drop the unbacked 2.0.0 rewrite promise from the boot warning
The warning no longer says the upgrade keeps access for empty models
lists, since no shipped code or public page backs that yet. It says
2.0.0 removes the defaults and how to keep today's access, and keeps
the advice for teamless all-team-models keys. The integration test
drops an empty-database assertion that ran before the check finished

* fix(proxy): serve Codex its own Bedrock catalog entries for Bedrock deployments
Codex builds separate catalogs for Bedrock's runtime and Mantle endpoints that turn off what Bedrock does not support yet. A model whose deployments run on Bedrock now takes its entry from those catalogs, vendored from Codex 0.166.0, instead of from Codex's OpenAI catalog.
* fix(proxy): keep Bedrock catalog entries from Codex releases that cannot decode them
codex debug models leaves out fields such as supports_parallel_tool_calls that Codex releases before 0.148.0 require, so a Bedrock entry now needs at least 0.148.0 as well as its source entry's minimum.

* fix(router): join default metadata tags after the request's tags

Merging default metadata under the request let a caller's mask_input or mask_output false switch off masking an admin set in default_litellm_params.metadata.

Several integration tests on main still assert behavior that later changes replaced on purpose, so they fail on every scheduled run, and one of them stops the whole sdk group at import.
The batch cost case expected cached tokens to bill at the Batch input price when a price row has no Batch cache price. Since #50062 they bill at the Standard cache price, so the case now expects 0.000235 input cost and is renamed to say so.
The OTel v2 attribute test pinned langfuse_otel and langtrace as carrying no request metadata baggage. Since #50373 every OTel v2 destination carries it, so all seven callbacks share one expectation and the Langfuse baggage test that was deferred under LIT-9128 runs again.
The clean-EOF outage test trips its database relay on the text of the spend log insert. The ledger writes that insert without the "public" schema prefix, so the relay never tripped and the test timed out before it checked anything. The trigger now matches the insert on both write paths.
The usage routing tests expected cooldown, tpm and rpm keys in one MGET. Since #50170 the cooldown keys are read in their own MGET, at most once per DEFAULT_COOLDOWN_REDIS_READ_INTERVAL_SECONDS. Both the proxy and the SDK test now expect the two MGETs, and the proxy test waits out that interval after its /model/info poll, which reads the same keys.
The concurrent deployment delete test held its writer inside Router._update_deployment_indices_after_removal, which went away with the Python router core in #50178, so the file failed at import and stopped the whole sdk group. It now holds the writer where the registry reads the model list again after router-core applied the change.
Python stores a unary messages response from a background cache write task that runs after the router stamps _hidden_params, so the entry carries model_id and the router headers and a later hit returns x-litellm-cache-key. The native path stored the entry inside the native call, before the router saw the response. The async unary store is now deferred until the route encodes its public response and is handed to Python's own cache write task
When the client disconnects mid-stream, the native adapter now logs success for the chunks it delivered before teardown, so spend, SpendLogs and the key's budget and tpm reservations settle the same way they do on the Python path
The proxy records a client disconnect, with its 499 error information, in the stream generator's cleanup. The native teardown billed the stream before that cleanup, so the row had empty error information. A proxy stream torn down by cancellation now bills from the task's done callback, after the disconnect is recorded
A stream whose upstream body ends mid-frame reached proxy callers as a mapped APIConnectionError with status 500. Python's transport raises an unmapped httpx error at that point. The native body read now records a body cut and the host raises the same exception the active transport would
Python wraps a connect, DNS, TLS or reset failure in a synthesized 500 AnthropicError, which maps to InternalServerError. The native path surfaced these as APIConnectionError with the bug-report footer, which also changed cooldown decisions
The proxy bills the estimated prompt of a failed call only when the Timeout was caused by an httpx ReadTimeout. The native timeout now chains the same httpx timeout Python's client raises, so its failure row bills the prompt
Python rebuilds an upstream error response from the decoded body without content-encoding and content-length. The native failure now drops those wire headers, and a failure raised without an HTTP response states no headers at all, like Python
Python's async client wrapper stamps the effective timeout and num_retries on every failure, which the proxy reads for x-litellm-timeout and the router reads for retries. The native async paths skipped that wrapper, so error responses from Rust-served async calls had no x-litellm-timeout header
Python's async chat completions, responses, embeddings and messages entries hand the call to run_in_executor before they build the provider body, so a during_call guardrail started next to the call masks the request first. The native paths built their request without yielding, so masked text never reached the provider
The shared native_acall_hook now yields once and stamps the failure, and every async dispatch passes it as its native hook. OCR passes native_acall_hook_on_loop, which only stamps the failure, since its Python entry went through the client wrapper but built its request on the loop
Python's messages transform takes any JSON object from a 200 response and only adds stop_sequence, so a provider answering 200 with an error object reaches the client as 200 and the router counts a success. The native decoder turned it into a 500 APIConnectionError and a router failure. A JSON object that is not a message now passes through unchanged
A non-string extra_headers or deployment header value surfaced from the native handler as an APIConnectionError. It is now refused as an invalid request when the headers are collected, before the provider request is built or logged, so the caller gets a 400 BadRequestError naming the header and its type
Python logs the requested optional params, taken before the provider transform, as model_parameters. The native handler logged the transformed body, so a reasoning_effort request was logged as thinking and output_config. The request context now carries the requested params
Python updates model_call_details with the transformed request body before pre_call, so the logged messages are what was sent. The native adapter kept the caller's messages and compared params as JSON values, so an int 0 logged as 0.0
Python only records custom_llm_provider in model_call_details. The native adapter also wrote it into litellm_params, and the proxy reuses one logger across router hops, so a fallback hop's pre_call log showed the provider where Python shows null
Python only stamps cache_hit when a result came from the cache. The native adapter wrote False on every provider result
Python calls pre_call with the request body as a json user message, and a stream's spend-log cache_key is computed over that input. The native adapter logged the string Messages, so a streamed call's cache_key differed
* fix(messages): log native messages success once, after the proxy releases it
The proxy defers non-stream success logging past post-call guardrails, but the native host parked its log in its own slot and the release only ran for OCR, so a unary /v1/messages call served by Rust logged no success event, no SpendLogs row and no key, team, user or end-user spend. A deferred native success now parks in enqueue_deferred_logging with deferred_success_result, the same slots Python uses, so the proxy releases it like any other call and its guardrail step pruning and cost preparation see it too
Python runs sync success callbacks inside the deferred logging closure, so a post-call hook that blocks the response drops them. A parked native success now carries its sync callbacks and runs them on release
A refused first attempt and its fallback share one logger. Python logs the async success once, for the first attempt, so the native adapter now claims the async success log once across fallback attempts. Like Python, an attempt that loses the claim runs its sync callbacks only when logging is not deferred, and an internal call logs nothing
* test(messages): cover the deferred native success park and release
The proxy attaches its shared aiohttp session to every request and a default stream_timeout to every stream, and the messages detectors treated both as Python-only features, so no proxy request reached Rust. A shared session is only a connection-reuse hint and no native client reads it, so the common caller_client detector now fires only for an explicit client. The native messages call now takes the one timeout Python's messages handler resolves from timeout, request_timeout, stream_timeout and an httpx.Timeout, so no timeout shape keeps a messages call on Python
* feat(proxy): let a key's logging entry reference a proxy credential
A virtual key's metadata.logging entry can name a proxy credential with
litellm_credential_name. At request time the credential's values, which config
credential_list resolves through the secret manager at boot, are merged under the
entry's callback_vars, with the entry's own values winning. An entry whose
credential is not defined is dropped, so it never falls back to the proxy's own
callback environment.
Only proxy admins may change the logging entries of a key when the stored or
requested list holds a reference (403), and a reference to an undefined
credential is a 400. The check runs on key generate, update, team bulk update,
regenerate and /user/new, and compares decrypted entries so re-saving metadata
read back from /key/info is not a change.
Resolves LIT-10061
* fix(proxy): drop a key logging entry whose referenced credential holds no logging values
* fix(proxy): only require newly added credential references to exist on key writes
* fix(proxy): log a dropped credential reference as an error so /key/health reports it
* fix(proxy): gate credential references on bulk-created user keys
* fix(proxy): keep failing requests on keys with non-object logging metadata
A key whose stored metadata.logging is not a list of objects failed every
request with a 500 before this branch. The credential reference rewrite
turned those values into no entries, so the request quietly succeeded
without the key's logging. Raise a TypeError for those shapes again so the
request path behaves as it did on main, while empty values and objects with
unknown fields still go through the existing skip.
* test(proxy): audit cells for credential references across surfaces, v1, dropped entries and malformed logging
The malformed logging cell expects the base behavior that 7ac4ab1356
restored, a 500 for a key whose stored metadata.logging is not a list of
objects and a 200 for an empty list
* fix(proxy): keep a 500 for teams with non-object logging metadata
On main, a team whose stored metadata.logging held non-object items failed
chat requests with a 500, because AddTeamCallback(**item) raised a TypeError.
This branch switched to AddTeamCallback.model_validate, whose before-validator
raises AttributeError on those items, and the proxy maps AttributeError to a
400 invalid_request_error. Raise a TypeError for non-mapping items before
validation so the status matches main again, as the key path already does.
* fix(complexity_router): keep Claude Code subagent and side-request traffic off other agents' tier pins
Claude Code sends one x-claude-code-session-id for the main agent, every
subagent and their side requests. In user_turn mode a subagent's new ask
rewrote the parent's pin (#50099), and the agent progress summaries Claude
Code fires during a subagent run rewrote the subagent's pin to the cheapest
tier (#50444).
Subagent requests now get their own tier pin keyed on session id plus
x-claude-code-agent-id. Requests marked x-claude-code-request-class:
auxiliary route as housekeeping, and only main and subagent turns may write
a pin. Without the hint header, the summary and prompt-suggestion prompts
are matched as housekeeping sentinels.
* chore(ui): regenerate schema.d.ts for the housekeeping_patterns description
* fix(complexity_router): let the request-class hint only mark housekeeping, not suppress pin writes
A client-sent request class must not decide whether a decision is saved.
Tagging a real ask as workflow or auxiliary dropped its routing decision,
so later continuations replayed an older pin with the new history. The
auxiliary hint now only routes the request through the housekeeping path,
which is already never pinned and defers to custom classifiers and
keyword rules.
* test(complexity_router): cover the auxiliary hint on a prompt no sentinel matches

* fix(proxy): read an absent team membership row as zero spend under fail-closed budget enforcement
A team user under a default member budget has no LiteLLM_TeamMembership row until spend is persisted. SpendCounterReseed.from_db returned None for that absent row, the same value as a failed DB read, so fail_closed_budget_enforcement rejected every request from that user with 503. The DB answering that the row is absent is a verified zero, so from_db now returns 0.0 for a team-member counter without a row and still returns None when the read fails.

* fix(proxy): only read an absent membership row as zero when the team member key parses unambiguously
A team_id or user_id containing ":" makes the counter key split onto the wrong membership row, so that miss keeps returning None instead of a verified zero. Type the new unit tests.
* fix(proxy): refuse a fail-closed team member with no membership row with a 403 that names /team/member_add
Replaces the earlier reading of an absent LiteLLM_TeamMembership row as verified zero spend. A key minted with team_id and user_id but no /team/member_add has no row and the spend writer never creates one, so admitting it at zero would leave its member spend tracked only in Redis. With fail_closed_budget_enforcement on, _check_team_member_budget now rejects that key with a 403 that names the user, the team and the member_add call, before any spend read. With the flag off nothing changes. The membership load raises on a database failure and returns None only for a genuinely absent row, so the 403 never fires during an outage. spend_counter_reseed.py and the counter prefix constant go back to main.
* test(proxy): drive the no-membership 403 tests through the real membership and spend readers
Fake Postgres rows and the FakeSpendCounters double stand in for the external stores instead of patching get_team_membership and get_current_spend. Strip CR/LF from the ids in the fail-closed warning log.
* fix(proxy): read fail_closed_budget_enforcement from general_settings in the membership check
Importing proxy_server's private helper grew reportPrivateUsage past the type gate ceiling. Type the integration helper's return as JsonValue.
* fix(proxy): expose fail_closed_budget_enforcement_enabled for the membership check
Reading general_settings directly from auth_checks grew the unknown-type counts past the type gate ceiling; a small public wrapper in proxy_server keeps the gate flat.
* test(proxy): drop docstrings that restate the no-membership tests
