From e2932d22c0b6d6e0a01c4346fe304525eed9bf8e Mon Sep 17 00:00:00 2001 From: Nitish Agarwal <1592163+nitishagar@users.noreply.github.com> Date: Thu, 18 Jun 2026 14:06:36 +0530 Subject: [PATCH 001/684] fix(spend-tracking): hash raw api keys before persisting to spend logs (#30670) The Request Logs "Key Hash" column binds to the SpendLogs metadata user_api_key field, which _get_spend_logs_metadata copied verbatim from request metadata without hashing. The top-level api_key column only hashed values starting with sk-. So a non-sk- passthrough provider key, or a Bearer-prefixed key on paths that do not strip it, could be persisted and shown in plaintext. A single helper now redacts both fields at the SpendLogs builder: it strips a Bearer prefix, passes through values already a sha256 hash or hashed-jwt- identifier, and otherwise hashes with hash_token. sk- keys still map to the same canonical hash, so log and spend correlation is unchanged --- .../spend_tracking/spend_tracking_utils.py | 42 ++- .../test_spend_tracking_utils.py | 270

11:22:01 +1000 Subject: [PATCH 021/684] feat(models): swap SCX.ai catalog to GLM-5.2 and Qwen3.8 Max Replaces the five launch models with the two that SCX.ai now leads on. Both are live on api.scx.ai and both were verified against it for tool calling, json_object and json_schema output, reasoning, prompt caching, and, for Qwen3.8 Max, image input Pricing follows SCX's published USD rates. GLM-5.2 lands at $0.55/M input and $1.9255/M output, tracking the recent GLM-5.2 market repricing; Qwen3.8 Max at $1.815/M and $5.4461/M sits under the only other seller of that model, and is the first Qwen3.8 Max entry in the catalog Also corrects a metadata bug the removed entries carried: they set max_tokens equal to max_input_tokens, conflating the context window with the output cap. Both new entries declare a max_output_tokens of 131072, which is what the endpoint's own validator enforces The Add Model placeholder moves to scx-ai/GLM-5.2 now that MiniMax-M2.7 is no longer in the catalog --- ...odel_prices_and_context_window_backup.json | 84 ++++++------------- .../provider_create_fields.json | 2 +- model_prices_and_context_window.json | 84 ++++++------------- .../llms/openai_like/test_scx_ai_provider.py | 34 ++++---- .../components/provider_info_helpers.test.tsx | 2 +- .../src/components/provider_info_helpers.tsx | 2 +- 6 files changed, 75 insertions(+), 133 deletions(-) diff --git a/litellm/model_prices_and_context_window_backup.json b/litellm/model_prices_and_context_window_backup.json index 2f47643da50..dee3cbdd054 100644 --- a/litellm/model_prices_and_context_window_backup.json +++ b/litellm/model_prices_and_context_window_backup.json @@ -33546,72 +33546,40 @@ "supports_vision": true, "source": "https://cloud.sambanova.ai/plans/pricing" }, -

Parse cacheDetails (when present) into CacheCreationTokenDetails so the correct rate applies to each portion. No cacheDetails in the response (older models/regions) keeps the previous behavior.

Anthropic usage now goes through `AnthropicConfig.calculate_usage`, the same transformation the non-streaming path uses, and the chunk is priced through the call's logging object when there is one so it inherits `custom_pricing`, `custom_llm_provider`, `base_model` and `router_model_id`, falling back to `completion_cost` by model name. `calculate_usage` only reads its `usage_object`, so it now takes a `Mapping`.

Every test registers its own deployment with a distinct custom rate per component, so a component billed at the wrong rate cannot pass. The shared helpers in cost_rows.py encode the one thing the two surfaces disagree on: the spend row's input_cost is gross of cache while the response's cost-input header is net of it. ---

The dedicated /openai_passthrough prefix used to be swallowed by the provider-scoped /{provider}/v1/files and /{provider}/v1/batches routes, which bound "openai_passthrough" as a provider name and failed inside the gateway before ever reaching OpenAI. Two tests now upload a file and list batches through that prefix and assert OpenAI's own objects come back. Streamed /openai_passthrough/v1/responses and /openai_passthrough/v1/embeddings are relayed to OpenAI but still have to be costed, since the customer budgets against this traffic. Both used to land a row the gateway could not use: the streamed responses call logged a zero-cost row under a random id, and embeddings wrote no row at all. Each test now reconciles the logged spend and token counts against the response the caller was actually served. GET /v1/files narrowed its data to the caller's own rows but left first_id and last_id addressing the shared provider account's page, handing any caller raw provider file ids belonging to other tenants. The new test asserts both cursors address rows in the page the caller can see. ResourceManager.defer now accepts any callable rather than one returning None, so a delete that answers with a response model can be deferred as-is. --- tests/e2e/batches/batch_client.py | 7 + tests/e2e/batches/test_batches_e2e.py | 34 +++++ .../coverage_registry/llm_conversational.yaml | 1 + .../llm_nonconversational.yaml | 4 + tests/e2e/lifecycle.py | 9 +- .../e2e/llm_translation/passthrough_client.py | 132 +++++++++++++++++- .../llm_translation/test_passthrough_e2e.py | 124 +++++++++++++++- 7 files changed, 305 insertions(+), 6 deletions(-) diff --git a/tests/e2e/batches/batch_client.py b/tests/e2e/batches/batch_client.py index 5cc5d1dae3b..968a357e8af 100644 --- a/tests/e2e/batches/batch_client.py +++ b/tests/e2e/batches/batch_client.py @@ -40,8 +40,15 @@ class FileObject(BaseModel): class FileList(BaseModel): + """GET /v1/files page.

mubashir1osmani Date: Thu, 20 Aug 2026 15:59:34 -0400 Subject: [PATCH 078/684] test(e2e): pin query params and multipart form fields as replay match-key identity The canonical request already folds

The user, database name, and schema used to be interpolated raw, so encoding an already-encoded DATABASE_USER like svc%40corp turned it into svc%2540corp and Postgres rejected the login with P1010. Decoding before encoding is idempotent, so a pre-encoded value comes out byte for byte as it went in while a raw UPN still gets encoded. An unreadable IAM_TOKEN_DB_AUTH or AZURE_POSTGRESQL_AUTH now fails startup naming the variable and the value. Reading a typo like "enabled" as off would silently downgrade an operator from token auth to password auth, and the first sign of it would be the server refusing the connection. The proactive refresh loop floors its sleep at 30 seconds. azure-identity hands back its cached token when a renewal fails inside its own window, so a token whose expiry never advances used to compute a zero sleep and spin the loop, re-minting and recreating the Prisma query engine every pass.

cache fields A streaming chat completion that ends early (client disconnect, or the proxy cutting the stream at LITELLM_MAX_STREAMING_DURATION_SECONDS) wrote a spend log row with spend 0.0, prompt_tokens 0 on the proxy-cut path, and no cache fields in usage_object. The proxy restamps chunk.model in place to the client-facing alias, so the partial response rebuilt from those chunks priced the unmapped alias and came out at 0. The failure path also rebuilt usage without the request messages, so prompt tokens counted to 0, and a cut stream never sees the final usage event that normally zero-fills the cache fields. Restamp the rebuilt partial response with the wrapper's real model before cost calculation on both the disconnect and the failure paths, pass the request messages when rebuilding usage on the failure path, and zero-fill missing cache usage fields the way completed streams already do. --- .../litellm_core_utils/streaming_handler.py | 19 +++- litellm/proxy/common_request_processing.py | 9 ++

Route the job's DB calls through call_with_db_reconnect_retry so a transport blip costs one reconnect instead. Reads replay on any transport error, since re-running a SELECT has nothing to double-apply. Writes are non-idempotent, a reset assigns spend = 0 unconditionally, so they narrow to DB_RETRY_SAFE_ERROR_TYPES: only a ConnectError proves the statements never reached the database. A post-send error like ReadError or ReadTimeout leaves the commit outcome unknown, and replaying one that already landed would erase whatever was spent since, so those keep the pre-existing behaviour of failing the tick.

Split the group the same way MCP is split: agent_inference_routes stays on the data plane, agent_management_routes joins management_routes, and agent_routes remains their union for keys configured with allowed_routes=["agent_routes"]. Non-admin callers reached agent CRUD through llm_api_routes before, so the management paths also join self_managed_routes and the llm_api_routes virtual key carve-out; the handlers already scope reads by role and 403 non-admin writes. Both new groups are tuples, so check_route_access now takes a Sequence and matches wildcards through a generator instead of materializing an intermediate list on every call. --- litellm/proxy/_types.py | 27 ++++- litellm/proxy/auth/route_checks.py | 30 ++++-- ruff-strict-budget.json | 2 +- .../proxy/auth/test_route_checks.py | 60 +++++++++++ .../proxy/auth/test_route_checks.py | 101 ++++++++++++++++++ 5 files changed, 207 insertions(+), 13 deletions(-) diff --git a/litellm/proxy/_types.py b/litellm/proxy/_types.py index 8856e68698a..6b471ed795b 100644 --- a/litellm/proxy/_types.py +++ b/litellm/proxy/_types.py @@ -515,15 +515,28 @@ class LiteLLMRoutes(enum.Enum): # allowed_routes=["mcp_routes"], which should cover both halves. mcp_routes = mcp_inference_routes + mcp_management_routes - agent_routes = [ - "/v1/agents", - "/v1/agents/{agent_id}", + # A2A agent invocation / discovery routes — data-plane.

Tokenizing is O(prompt) and ran inline, so admitting one large request stalled every other request the worker was serving. Count the input tokens once per request and reuse the counts for both estimates. Prompts above 30K characters of input text are counted in a worker thread so the event loop stays free. The size heuristic renders the body rather than walking its values, so tool-schema property names count toward the threshold, and it sizes every field the counter tokenizes, tool_choice included.

Aug 2026 16:09:07 -0700 Subject: [PATCH 119/684] fix(token_counter): stop large token counts from blocking the proxy event loop (#37697) tiktoken's BPE merge loop is quadratic in the length of a single regex piece, so a long run of one repeated character turns a multi-MB payload into minutes of CPU. Encoding in bounded chunks makes that linear, at a drift of at most ~1 token per chunk boundary. Chunking alone only makes the stall shorter, so the async paths now count in a worker thread: tiktoken releases the GIL for its Rust encode, so the loop keeps serving other requests while a count is in flight. The /utils/token_counter endpoint awaits the new atoken_counter, and the router's async deployment selection counts off-loop and hands the result to _pre_call_checks instead of making it count inline. The chunk size knob is bounded to [1, 4096]: a non-positive value used to raise or silently report zero tokens, and an arbitrarily large one restored the quadratic cost this exists to remove. Out-of-range and unparseable values warn and fall back to 1024.

Context-window From 47731303b53a2bebd1ded4a115edb3901ab8aee8 Mon Sep 17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Thu, 20 Aug 2026 16:09:30 -0700 Subject: [PATCH 120/684] fix(caching): bound the semantic cache embedding lookup A semantic cache lookup embeds the prompt before the request reaches the LLM, and that embedding call carried no deadline of its own. It inherited the 6000s request timeout and the Router's num_retries, so an embedding endpoint that is down or unroutable parked every proxied request for minutes and gave back nothing but x-litellm-semantic-similarity 0.0 once it finally gave up. The lookup now runs on its own short deadline, 5s by default, with retries off so failures cannot stack. Redis, Valkey and qdrant all pick it up, and the deadline is settable per cache with semantic_cache_embedding_timeout or globally with SEMANTIC_CACHE_EMBEDDING_TIMEOUT_SECONDS. --- litellm/caching/_embedding_router.py | 8 + litellm/caching/caching.py | 5 + litellm/caching/qdrant_semantic_cache.py | 34 +++- litellm/caching/redis_semantic_cache.py | 43 +++-- litellm/caching/valkey_semantic_cache.py | 3 + litellm/constants.py | 4 + litellm/main.py | 6 +- .../caching/test_redis_semantic_cache.py | 154 ++++++++++++++++++ 8 files changed, 233 insertions(+), 24 deletions(-) diff --git a/litellm/caching/_embedding_router.py b/litellm/caching/_embedding_router.py index 8dfcddf158a..cec25634bb8 100644 --- a/litellm/caching/_embedding_router.py +++ b/litellm/caching/_embedding_router.py @@ -16,6 +16,7 @@ from collections.abc import Sequence from typing import TYPE_CHECKING, Any, Final import litellm +from litellm.constants import SEMANTIC_CACHE_EMBEDDING_TIMEOUT_SECONDS if TYPE_CHECKING: from litellm.router import Router @@ -60,6 +61,13 @@ def resolve_embedding_max_input_tokens( return deployment_max_input_tokens +def resolve_embedding_timeout(configured_timeout: float | None) -> float: + """Explicit cache setting first, else the short semantic-cache default.""" + if configured_timeout is not None: + return configured_timeout + return SEMANTIC_CACHE_EMBEDDING_TIMEOUT_SECONDS + + def truncate_embedding_input(prompt: str, embedding_model: str, max_input_tokens: int | None) -> str: """Keep only the first ``max_input_tokens`` tokens of ``prompt`` for the embedding call.""" if max_input_tokens is None: diff --git a/litellm/caching/caching.py b/litellm/caching/caching.py index 6b68ae98111..cefe6aae9ed 100644 --- a/litellm/caching/caching.py +++ b/litellm/caching/caching.py @@ -98,6 +98,7 @@ class Cache: qdrant_semantic_cache_embedding_model: str = "text-embedding-ada-002", qdrant_semantic_cache_vector_size: int | None = None, semantic_cache_embedding_max_input_tokens: int | None = None, + semantic_cache_embedding_timeout: float | None = None, # GCP IAM authentication parameters gcp_service_account: str | None = None, gcp_ssl_ca_certs: str | None = None, @@ -124,6 +125,7 @@ class Cache: qdrant_collection_name (str, optional): The name for your qdrant collection.

The per-model `rust: true` opt-in now covers /chat/completions for both providers. The core accepts an allowlisted subset (text conversations, non-streaming) and returns CoreError::Unsupported for anything else, so tool calls, multimodal content and streaming fall back to the Python path transparently.

Those users land in the Admin UI with no username, email, groups or teams. Adds an opt-in `GENERIC_INCLUDE_TOKEN_CLAIMS` that merges token claims into the UserInfo response before the existing `GENERIC_USER_*_ATTRIBUTE` mappings run. Precedence is UserInfo, then id_token, then access token, and it applies to both the PKCE and non-PKCE login flows. With the flag unset, behavior is unchanged.

Subject: [PATCH 129/684] fix(proxy): claim batch cost rows atomically so multi-pod polling can't double-bill (#37685) Every pod and uvicorn worker schedules its own CheckBatchCost poller against the shared managed-object table, so two of them can select the same completed batch in one polling window and both write an aretrieve_batch spend log for it, counting that batch's cost twice. Claim the row with a compare-and-swap on batch_processed, and skip the batch when another pod already holds it. The claim sits immediately before the spend log is written rather than before the results fetch, because batch_processed is also what blocks deletion of the files the fetch reads and what keeps an unbilled row selectable by later poll cycles, so claiming up front would strand the spend of any worker that died mid-fetch. A failed spend log write hands the row back.

How that surfaced depended on the outage shape: httpx.ConnectTimeout was missing from DB_CONNECTION_ERROR_TYPES so it fell through to the generic auth handler as a 401 with an empty detail, while a read timeout took the database path and reported a healthy database as unreachable. Transport failures are now retried three times with a short backoff, and the last-known-good JWKS stays usable for a bounded window past public_key_ttl. That window is public_key_stale_ttl, a new config field defaulting to 3600s and settable to 0 to fail closed. It is checked on every read against the current setting rather than baked into the cache entry when it is written, so lowering it binds immediately instead of waiting for entries written under the old value to age out, which matters because a shared cache survives the restart an operator performs to make the change take effect. A copy whose write time cannot be established is not servable. Only httpx.TransportError unlocks the stale copy, so an identity provider that answers at all, including with a narrowed key set, revokes on the next refresh. Every stale serve logs the kid it authenticated, how long ago that copy was refreshed, and how long until it stops being trusted. A sustained outage is remembered for 30s per key url, so it costs one fetch per window instead of three timeouts per request serialised behind the refresh lock. Non-200 JWKS responses now raise instead of being cached as the key set, which previously let an error body overwrite the last-known-good copy. An unreachable identity provider with no cached copy left returns 503 auth_provider_unavailable.

ConditionalPublicModelName kept a `tableKey` counter and bumped it from an effect on every run to force the mappings table to remount. That was harmless under antd, whose useWatch handed back the stored array. React Hook Form's useWatch returns a fresh array each render, so the effect's dependency changed every render, the effect bumped state again, and the render loop never settled. The table is driven by its `data` prop, so the remount counter buys nothing: drop it, key the effects off the selection contents rather than the array identity, and write model_mappings only when they actually change. The two `react-hooks/set-state-in-effect` suppressions on this file, which were recording exactly this bug, go with it. --- ui/litellm-dashboard/eslint-suppressions.json | 3 -- .../conditional_public_model_name.test.tsx | 44 +++++++++++++++++++ .../conditional_public_model_name.tsx | 23 ++++++---- 3 files changed, 58 insertions(+), 12 deletions(-) diff --git a/ui/litellm-dashboard/eslint-suppressions.json b/ui/litellm-dashboard/eslint-suppressions.json index 3bc93b7ebc4..b7c578d8ec6 100644 --- a/ui/litellm-dashboard/eslint-suppressions.json +++ b/ui/litellm-dashboard/eslint-suppressions.json @@ -1468,9 +1468,6 @@ }, "local/no-complex-jsx-arrow": { "count": 1 - }, - "react-hooks/set-state-in-effect": { - "count": 2 } }, "src/components/add_model/handle_add_auto_router_submit.tsx": { diff --git a/ui/litellm-dashboard/src/components/add_model/conditional_public_model_name.test.tsx b/ui/litellm-dashboard/src/components/add_model/conditional_public_model_name.test.tsx index 967fc9c458a..07ec36639b4 100644 --- a/ui/litellm-dashboard/src/components/add_model/conditional_public_model_name.test.tsx +++ b/ui/litellm-dashboard/src/components/add_model/conditional_public_model_name.test.tsx @@ -1,8 +1,28 @@ import { render, screen } from "@testing-library/react";

Google retired the whole Imagen family across Vertex and the Gemini API, so there is no Imagen id left to point at. The class is removed rather than repointed: Vertex image generation is already covered live by TestVertexAIGeminiImageGeneration on vertex_ai/gemini-2.5-flash-image, and the Imagen request and response transformations keep their offline coverage in tests/test_litellm/llms/vertex_ai/image_generation/. Only live call sites move. Remaining references to the old ids sit in offline cost-map and transformation tests, where the string is a lookup key and no request leaves the process. * chore(lint): ratchet the TQ005 ceiling down to the count this branch reached Removing the retired TestVertexImageGeneration class cleared one TQ005 violation, so the gate demands the limit come down with it. make lint-budget-update only lowers a limit by the delta a branch cleared, and this ceiling already sat 2 above the base count, so the tool landed on 2834 while the gate wants the limit at or below the 2832 this branch reached. The remaining 2 are that stale headroom, which is exactly what the gate is asking to reclaim. --- test-quality-budget.json | 2 +- tests/image_gen_tests/test_image_generation.py | 14 -------------- tests/llm_translation/test_openai.py | 4 ++-- .../test_built_in_tools_cost_tracking.py | 2 +- tests/test_openai_endpoints.py | 2 +- 5 files changed, 5 insertions(+), 19 deletions(-) diff --git a/test-quality-budget.json b/test-quality-budget.json index 17baf64601b..fcb29c3191d 100644 --- a/test-quality-budget.json +++ b/test-quality-budget.json @@ -12,7 +12,7 @@ "limit": 770 }, "TQ005": { - "limit": 2835 + "limit": 2832 }, "TQ006": { "limit": 34 diff --git a/tests/image_gen_tests/test_image_generation.py b/tests/image_gen_tests/test_image_generation.py index 33dcdbb57a5..ad141a651e8 100644 --- a/tests/image_gen_tests/test_image_generation.py +++ b/tests/image_gen_tests/test_image_generation.py @@ -105,20 +105,6 @@ def load_vertex_ai_credentials(): os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = os.path.abspath(temp_file.name) -class TestVertexImageGeneration(BaseImageGenTest): - def get_base_image_generation_call_args(self) -> dict: - # comment this when running locally - load_vertex_ai_credentials() - - litellm.in_memory_llm_clients_cache = InMemoryCache() - return { - "model": "vertex_ai/imagen-3.0-fast-generate-001", - "vertex_ai_project": "litellm-ci-cd", - "vertex_ai_location": "us-central1", - "n": 1, - } - - class TestVertexAIGeminiImageGeneration(BaseImageGenTest): """Test Gemini image generation models (Nano Banana)""" diff --git a/tests/llm_translation/test_openai.py b/tests/llm_translation/test_openai.py index 1a14b00c7d7..61819dfc860 100644 --- a/tests/llm_translation/test_openai.py +++ b/tests/llm_translation/test_openai.py @@ -422,7 +422,7 @@ def test_openai_web_search(): """Makes a simple web search request and validates the response contains web search annotations and all expected fields are present""" litellm._turn_on_debug() response = litellm.completion( - model="openai/gpt-4o-search-preview", + model="openai/gpt-5-search-api", messages=[ { "role": "user", @@ -442,7 +442,7 @@ def test_openai_web_search_streaming(): # litellm._turn_on_debug() test_openai_web_search: Optional[ChatCompletionAnnotation] = None response = litellm.completion( - model="openai/gpt-4o-search-preview", + model="openai/gpt-5-search-api", messages=[ { "role": "user", diff --git a/tests/logging_callback_tests/test_built_in_tools_cost_tracking.py b/tests/logging_callback_tests/test_built_in_tools_cost_tracking.py index 335661d46d0..0e73ad834da 100644 --- a/tests/logging_callback_tests/test_built_in_tools_cost_tracking.py +++ b/tests/logging_callback_tests/test_built_in_tools_cost_tracking.py @@ -105,7 +105,7 @@ async def test_openai_web_search_logging_cost_tracking( from litellm._uuid import uuid request_kwargs = { - "model": "openai/gpt-4o-search-preview", + "model": "openai/gpt-5-search-api", "messages": [ { "role": "user", diff --git a/tests/test_openai_endpoints.py b/tests/test_openai_endpoints.py index 0d44064997e..ab43d1acb00 100644 --- a/tests/test_openai_endpoints.py +++ b/tests/test_openai_endpoints.py @@ -550,7 +550,7 @@ async def test_proxy_all_models(): async with aiohttp.ClientSession() as session: # call chat/completions with a model that the key was not created for + the model is not on the config.yaml await chat_completion( - session=session, key=LITELLM_MASTER_KEY, model="groq/llama-3.1-8b-instant" + session=session, key=LITELLM_MASTER_KEY, model="groq/openai/gpt-oss-120b" ) await chat_completion( From e00301703f2f4274f77177c02bba04f02155a280 Mon Sep 17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Thu, 20 Aug 2026 17:16:53 -0700 Subject: [PATCH 142/684] feat(cognition): give Cognition its own provider identity Cognition serves an OpenAI-compatible /v1/chat/completions endpoint, so it has been onboarded as custom_llm_provider: openai. That books its traffic as OpenAI, which means OpenAI-specific cost discounts and provider-level reporting apply to it. Registers cognition through the JSON provider registry: a providers.json entry with COGNITION_API_KEY and COGNITION_API_BASE, LlmProviders.COGNITION, the constants.py provider lists, cost map entries for swe-1.6 and swe-1.7, the provider endpoints matrix, the dashboard provider fields, and tests. JSON providers can now also be resolved from their base url alone, so an api_base pointing at a known provider no longer falls through to an unresolved provider. --- README.md | 1 +

(#37691) The read replica never received the operator's DB pool settings, so its Prisma pool fell back to `num_physical_cpus * 2 + 1` and the configured cap was not enforced. Both startup paths now pass the same params to the reader: the CLI, and the componentized entrypoints that go through `DatabaseURLSettings.apply_to_env`. Only pool and timeout params are inherited, through a single allowlist both paths share. Anything that decides which tables a query resolves against stays on the writer, including entries smuggled in through `database_extra_connection_params`, so a writer `search_path` cannot repoint reader queries. Params the operator pinned on the replica URL still win.

Surfacing the failure fixes that, but aborting on the first failed write leaves the rest of the batch unattempted on top of unrolled-back, which is worse than what it replaces. Every roster write in a reconciliation is now attempted, and the ones that did not land are reported together, naming each failed add and remove. Rollback would be the other option and it is not safe here: the compensating write can fail too, and it can strip a membership that pre-dated the push. SCIM reconciliation is idempotent, so a named partial failure is what the IdP's next push needs to close the gap. The reported status still follows the failures, so a unanimous 404 stays a 404 and only a batch whose failures disagree falls back to 500.

The job now takes the shared PodLockManager lease, so one pod sweeps per tick. A deployment with no Redis keeps its previous behavior, and a Redis that cannot answer sweeps unguarded rather than stranding every expired budget at its cap. The per-window scan read every row carrying budget_limits in one statement, so its cost grew with the deployment's key count. It is now keyset-paginated and walks to the end of the table on every sweep. A per-run cap would need a resume position, and no pod can hold one because the lease rotates between ticks, so the strictly advancing cursor is what terminates the walk. Found and updated rows were also JSON-serialized into the service hook's metadata and into debug lines on every chunk, on the event loop, whether or not anything consumed them. The hooks now carry counts, and the debug payload is deferred until a record is actually emitted.
