 ### Fixed
 
+- **user**: `litellm_user` updates no longer send `blocked`, which `/user/update` writes into the user table where no such column exists, so every update failed with a 400 (`Could not find field at upsertOneLiteLLM_UserTable.create.blocked`). Create still sends `blocked`, including `false`, so a `default_internal_user_params.blocked` on the proxy cannot block the auto-created key. Changing `blocked` after creation has no effect, since the proxy has no user-level block; use `litellm_key_block` instead
 - **model**: `litellm_model` refresh now reads the `{"data": [...]}` envelope `/model/info` returns, so `model_info` fields changed outside Terraform show up as drift instead of silently keeping the previous state
 - **key**: An update that changes `team_id` and fails because the key was already cascade-deleted along with its previous team now recovers by recreating the key under the new team, instead of aborting the apply. The key's absence is confirmed against the proxy first, so an unrelated failure still errors out, and a `team_id` change between two teams that both still exist stays a plain in-place update
 - **credential**: create now reports a `credential_name` collision as a clear error naming the `terraform import` command that adopts the existing credential, instead of surfacing the proxy's raw 500 with a Prisma `Unique constraint failed` message. New `adopt_existing` argument (default `false`) opts into taking the existing credential over during create, which makes `apply` idempotent again once state loses track of a credential that still exists on the proxy. Requires a proxy that answers 409 on the collision; older proxies are still detected by their 500 message

@@ -10,13 +10,25 @@ Use `tests/integration/run.py management`, `accounting`, `database`, `providers`
 
 Management also requires `INTEGRATION_PEER_URL`, `REDIS_HOST` and `REDIS_PORT`. CircleCI starts two directly addressed proxy processes sharing only that job's stores. The test-only CLI wrapper supplies enterprise route entitlement, following the existing behavior suite's convention. It does not qualify license validation; run it with one worker and no reload
 
-The generated lifecycle models use 20 examples, eight steps, generation and shrinking, with isolated resources per example. HTTP operation caps include generation and shrinking and exempt cleanup. Local qualification defaults to seed 4106601 and canonical order; CircleCI derives exploration and ordering seeds from the checked-out revision and workflow ID. The ordering seed shuffles the file order and the test order inside each file but keeps each file's tests together, so module fixtures are built once per file. Use `--seed` and `--order-seed` to reproduce a run. Actual installed Hypothesis version, settings, seeds and collected order are written beside the execution manifest
+The generated lifecycle models use 20 examples, eight steps, generation and shrinking, with isolated resources per example. HTTP operation caps include generation and shrinking and exempt cleanup. Local qualification defaults to seed 4106601 and canonical order; CircleCI derives exploration and ordering seeds from the checked-out revision and workflow ID. The ordering seed shuffles files, scoped fixture configurations and cases within each configuration. Cases sharing a module or class fixture parameter stay together, so shuffling does not repeatedly rebuild the same configuration
+
+CircleCI uses its built-in `circleci tests split --split-by=timings --timings-type=filename` to assign test files using the uploaded JUnit timings. Each file stays on one node, preserving its module and parametrized fixtures. Jobs default to one node. Parallelism should use the smallest node count that keeps the complete job, including setup and cleanup, within twenty minutes. A group that already finishes within that target on one node stays on one node. Management, accounting and management replica currently use four nodes. Providers and extensions use eight nodes; database and MCP use two, and fast suites use one. No job is configured above eight nodes. A single slow file can still determine a suite's runtime; split such a file along independent fixture boundaries rather than adding more nodes
+
+Every node collects the same candidate files before applying CircleCI's assigned file list. Its execution record retains the candidate inventory and the selected, passed and skipped cases. An empty assigned file list produces an empty shard, not a full-suite fallback. Every parallel group has a dependent census job that rejects an empty candidate inventory, missing shards, omitted cases and duplicate execution. Standard and replica runs keep separate workspace records
+
+Future change-based selection belongs before timing splitting. Pass the selected group files or node IDs to `run.py <group> --list` to list their files, then give those filenames to CircleCI. Run the same candidate selection on every node with `--shard-files <CircleCI-output-path> --shards <count> --shard-index <index>`. The census compares execution with the candidate inventory, while full-suite runs remain the default. CircleCI determines scheduling from timing history; timing data never selects or omits candidates. Use `--seed` and `--order-seed` to reproduce test generation and order. The installed Hypothesis version, settings, seeds and collected order are recorded beside the execution manifest
+
+A future selector must explicitly skip a group when no candidates apply; omitting positional candidates means the full group. Keep full runs on the default branch and scheduled workflows, and select the full affected groups when shared fixtures, CI configuration or an unknown dependency changes
 
 Reuse the existing canned provider handlers through `_support/upstream.py`. It rejects internal request fields and exposes actual received requests for independent assertions. Register every created resource for cleanup immediately, keep expected values independent of production calculations, and assert readback plus the runtime effect of a change
 
+Owned proxies disable `.env` loading by default. A contract testing dotenv behavior can explicitly set `PYTHON_DOTENV_DISABLED=0` in its owned environment. An explicit scratch writer database drops an inherited reader with a different database name; pass both database URLs when the contract needs a paired reader. Database relays close listeners, active connections and their event loops on teardown. Upstream startup failures reap the child process before returning the failure. Custom subprocesses, direct SQL and background tasks still need an explicit owner in the test
+
+Owned proxy workers configure a 32-thread executor before application startup, preserving additional worker startup hooks. Held synchronous provider calls must not consume a CPU-dependent executor limit before the rest of a fault burst can start. The proxy entrypoint imports LiteLLM inside `main`, so spawned workers begin supervision before importing the application. Worker healthchecks have a five-second deadline; application readiness and graceful teardown retain their separate longer deadlines. A fault that deliberately pauses Python before it can answer worker pings must supply a longer healthcheck through `extra_arguments`. Slow application startup is covered separately by the readiness deadline. Crash tests own their client tasks with `TaskGroup`, release held peers in `finally` and prove that the intended worker had active traffic before killing it
+
 The CircleCI workflow starts its own database and Redis, restricts test-phase egress to its owned services and writes JUnit plus an executed-node manifest. Missing setup, failed cleanup or a selected test with neither a passed call nor a skip fail qualification. Skipped nodes are listed under `skipped` in `execution.json`, so the skip reasons double as the open bug list. `GITHUB_FILES` in `run.py` lists the files excluded from the `run_integration.sh` selection
 
-There is no per-node manifest. A positional argument is a file of the group or a pytest node id inside one (`path::test[param]`), so one cell of a parametrized file can run alone. The runner fails only when pytest fails, when collection errors, or when a selected file collects zero tests. Older tests still carry `@pytest.mark.covers(...)` decorators; the marker stays registered so they collect, but the IDs are not checked against anything and new tests should not use it. The GitHub Actions coverage census reads the `GROUPS` literal in `run.py` and treats every `tests/integration/<directory>/test_*.py` file in a scheduled group as owned by CircleCI

 Provider sentinels currently use the controlled server, not live recordings. The provider shard also runs the existing strict replay controls for changed requests, exhausted interactions, leftover interactions and no provider connection. Future recorded scenarios must use that replay-only implementation; missing recordings cannot fall back to a real provider. The observation endpoint is destructive and the current selection runs serially against one owned upstream
 
@@ -30,15 +42,19 @@ Accounting cases compare persisted input and output cost components against lite
 
 Provider contracts exercise actual TCP requests with synthetic credentials and local protocol peers. The S3 verifier uses independently implemented equations, a published known-answer vector, a fixed signing clock and deliberately invalid signed requests. Bedrock cases clear ambient AWS credential sources and check the literal model path, loaded role references, STS requests and bearer-only behavior
 
+CircleCI runs providers on eight isolated nodes using its file timing splitter. Each node owns its services. The dependent providers coverage job verifies all eight execution records against the candidate case inventory and rejects missing, duplicate, failed or incomplete execution. The node's assigned filenames are saved in `node-files.txt` beside its execution record
+
 Streaming checks send real HTTP transfer chunks, including one-byte partitions, fragmented tools, incomplete transfers and a cancellation barrier. They assert meaningful text, tool arguments, final usage and persisted cost. The Redis recovery case owns a separate database and Redis process, uses the supported one-second circuit-breaker recovery setting, waits for the real subscriber and verifies response data in Redis after restart. CircleCI reuses its existing Redis image for that extra process; it never pulls an image during tests
 
 The `messages_endpoint/` directory holds `/v1/messages` endpoint contracts: native-provider backends under `providers/` (`anthropic`, `bedrock`, `gemini`) and the translation bridges (`responses_bridge`, `chat_bridge`) at the top level. It runs in the providers shard; `run.py` selects test files recursively under each scheduled directory
 
 The sdk shard exercises the SDK's own HTTP clients against local protocol peers with no gateway in the path, so a case here fails only when the client library or its wire behavior changes. The HTTP/2 case runs a hypercorn TLS peer offering h2 and http/1.1 over ALPN, drives the sync and async httpx handlers at it with `LITELLM_HTTP2` off and on, and asserts the version both the client and the peer observed on the wire. Put a test here only when it needs no proxy or database. CircleCI starts a local Redis for this shard like the others, so SDK-side caching cases that need a real Redis server belong here too; a case that reaches the gateway belongs in one of the other shards
 
-The extensions shard uses the built-in generic callback and guardrail transports. It checks callback correlation and credential exclusion, guardrail rewriting and denial, retained OpenAI consumers and A2A wire versions. CircleCI runs it on parallel nodes, and each node starts its own database, Redis, upstream and proxy and runs its share of the group's files serially, split by recorded timings with `circleci tests split`. Tests keep the isolation of a serial run; they still must not assume a particular set of sibling files. `run.py <group> --list` prints a group's files and `run.py <group> <file>...` runs a subset of them
+The extensions shard uses the built-in generic callback and guardrail transports.

The dependent coverage job verifies all eight execution records against the candidate case inventory. Tests must not assume a particular set of sibling files
 
-The mcp shard runs the MCP gateway against SDK peers owned by each test (`_support/mcp.py`): streamable HTTP, SSE and stdio peers, an OpenAPI-spec app, and an OAuth 2.1 authorization-server double. Every peer records the requests it receives so a test can assert what reached the peer, not only what the proxy answered. The shard runs with `INTEGRATION_WORKERS` set and with `INTEGRATION_COVERAGE=1`, which starts the proxy under `coverage run --parallel-mode` limited to the MCP modules and stores `coverage.txt` plus an HTML report with the job artifacts. A test that fails because the product is wrong is skipped with `pytest.skip("BUG: <symptom>")` so the skip list in `execution.json` is the open MCP bug list
+The security shard uses four pytest workers on an xlarge machine, each with a private database and Redis. Route sweeps use a new HTTP client for every call and share only the TLS verification context, so authentication and response cookies cannot cross callers. The canary rig supplies owned OpenAI and Anthropic endpoints and synthetic credentials and rejects attempted external egress
+
+The two mcp nodes own separate services and use the same case census as providers and extensions. Their coverage data is combined into one MCP report after both nodes finish. Each node runs the MCP gateway against SDK peers owned by each test (`_support/mcp.py`): streamable HTTP, SSE and stdio peers, an OpenAPI-spec app, and an OAuth 2.1 authorization-server double. Every peer records the requests it receives so a test can assert what reached the peer, not only what the proxy answered.

 Browser contracts live in `tests/e2e/ui/tests/integrationCritical` and run only through `tests/e2e/ui/integration.config.ts`. The expected browser results are listed in `expected.json` in that directory and checked by `.circleci/scripts/verify_integration_browser.py`. The CircleCI browser shard builds the checked-out dashboard, starts the owned proxy with that build, and verifies one exact browser result without retries or skips. The default Playwright selection excludes this directory. The focused project flow asserts the submitted create and clear values, fresh SQL state and actual blocked/restored serving while preserving model restrictions
