Summary

Routes outside the job path now get typed clients straight from dependency injection, instead of receiving the Stainless SDK client and wrapping it at each call site. After this, the only routes still on the old SDK dependency are the generated job routes, which a separate change handles. Part of removing the Stainless-generated SDK.

Changes

  • Models, files, jobs service, intake, hello-world, auditor, insights and agents routes take typed clients from the request-scoped typed-client dependency.
  • Models entity services and permission checks take typed files and secrets clients, and use the typed client errors.
  • Files keeps its delegated "act as the files service" secrets access. The typed client merges headers where the old one replaced them, so the helper now clears the caller's identity headers explicitly. A test covers this.
  • The jobs service dispatcher and result download take typed files and secrets clients.
  • Plugin functions receive typed clients from their route, matching what the local CLI already passes.
  • Small additive shared pieces: a sync typed-client dependency, a sync typed client option in the test client helper, and the filesets resource builds its old generated part lazily so it works with a typed client.
  • Test fixtures in these areas move to typed clients. One intake ingest test is rewritten onto the typed intake client.

One commit per area; reviewing commit by commit is easiest.

Not covered here: the generated job routes, controllers and backends that still build the old SDK, and a few auth tests that depend on shared test helpers still typed on the old SDK.

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with documentation updates
  • Documentation only
  • Contributor tooling or automation
  • CI, build, or test infrastructure

Quality Gates

  • Tests added or updated for changed behavior
  • Existing tests cover changed behavior — justification:
  • Tests not applicable — justification:
  • Documentation updated for user-visible behavior
  • Documentation not applicable — justification: internal dependency change with no API or user-visible change; the regenerated OpenAPI spec is unchanged.

Verification

  • Pull request title follows the repository's Conventional Commit format
  • Every commit includes an appropriate Signed-off-by: trailer
  • uv run pre-commit run -a passes, or any blocked checks are identified below
  • Targeted tests pass, or tests are marked not applicable above
  • No secrets, API keys, or credentials are included

Targeted validation:

  • Lint and format on touched files: clean.
  • Unit tests for every touched service, plugin and shared package: 6060 passed, 74 skipped.
  • Integration tests: models 120 passed; files 258 passed, 46 skipped (external storage tests need credentials and were skipped); jobs 7, hello-world 29, and intake all passed.
  • Agents unit tests: 1801 passed. 4 failures also fail on the base commit and are unrelated.
  • Type check: nothing new in touched files.
  • Pre-commit: all hooks pass.
  • OpenAPI regeneration: no change.

Summary by CodeRabbit

  • Improvements
    • File, job, model, and plugin workflows now use dedicated service clients, while preserving existing endpoint behavior.
    • Delegated secret access now applies service-specific request credentials.
    • Synchronous and asynchronous platform clients are available for service integrations, and test clients support synchronous platform clients.

📝 Walkthrough

Walkthrough

Typed Nemo clients replace legacy SDK dependencies across shared providers, files, jobs, models, plugins, and service integrations. Files, Secrets, Jobs, Agents, Models, and Workspaces clients are constructed from typed clients. Test fixtures now support typed clients and direct TestClient requests.

Changes

Typed client migration

Layer / File(s) Summary
Shared client dependencies and test context
packages/filesets/src/filesets/resources.py, packages/nemo_helix_plugin/src/nemo_helix_plugin/*, packages/nhx_common/src/nhx/common/service/*, packages/nhx_testing/src/nhx/testing/client.py
Adds synchronous Nemo client dependency injection and test-client support. Files resources construct generated resources lazily and reject private attribute delegation.
Files API and test migration
services/core/files/src/nhx/core/files/api/*, services/core/files/src/nhx/core/files/testing/utils.py, services/core/files/tests/*
Files endpoints use AsyncNemoClient. Secret resolution receives a Secrets client, and delegated resolution applies delegated principal headers. Tests and fixtures use typed clients and TestClient.
Jobs service and test migration
services/core/jobs/src/nhx/core/jobs/*, services/core/jobs/tests/*
Jobs dependencies create Files and Secrets clients from AsyncNemoClient. JobDispatcher receives those clients directly, and result downloads inject an AsyncFilesClient.
Models service and test migration
services/core/models/src/nhx/core/models/*, services/core/models/tests/*
Model and adapter services use an injected Files client. Provider endpoints use an injected Secrets client. Deployment services no longer receive an SDK client.
Plugin and service integrations
plugins/nemo-agents/src/nemo_agents_plugin/*, plugins/nemo-auditor/src/nemo_auditor/*, plugins/nemo-data-designer/src/nemo_data_designer_plugin/*, plugins/nemo-insights/src/nemo_insights_plugin/*, services/hello-world/*, services/intake/*
Plugin and service endpoints use typed Nemo clients and typed service-client factories. Analysis-run submission receives Agents and Models clients directly.

supported FilesClient methods: replace `files.list` with `files.list_files` and
consume its result via `.data()`, and replace `files.download_content` with
`files.download_file` and read the response via `.read()`. Use the correct

Route handlers and service dependencies now receive AsyncFilesClient and
AsyncSecretsClient derived from the request-scoped AsyncNemoClient instead
of an AsyncNeMoHelix adapted at each call site. ModelEntityService and
AdapterEntityService take the Files client directly and list fileset files
through it. ModelDeploymentService drops its unused SDK parameter.

Adds NemoClient as a client_type and ClientContext.client so sync test
fixtures can hold a typed platform client instead of NeMoHelix.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
FilesResource and AsyncFilesResource construct the generated sub-resource on
first passthrough access instead of in __init__, so a typed NemoClient can
back the high-level upload, download, list and delete operations.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
Fileset, HF and OTLP route handlers receive the request-scoped
AsyncNemoClient. resolve_storage_secrets takes an AsyncSecretsClient, and
resolve_storage_secrets_for_user derives the service:files on-behalf-of
client from the request client with with_headers, clearing the caller's
own principal headers before applying the delegated ones.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
Integration fixtures yield NemoClient (via ClientContext) instead of
NeMoHelix. Typed clients are built with from_client, the FilesResource
fixture wraps the typed client, and the raw TestClient fixture is renamed
test_client. create_fileset in nhx.core.files.testing takes a FilesClient.
No assertions change. tests_filesets_with_auth_secrets.py stays on
NeMoHelix because it depends on nhx.testing.utils.as_user and
grant_workspace_role.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
JobDispatcher takes AsyncFilesClient and AsyncSecretsClient instead of an
AsyncNeMoHelix adapted per call, and dep_dispatcher derives both from the
request-scoped AsyncNemoClient. create_job no longer threads a separate
SDK into the dispatcher, and download_job_result uses the typed
download_from_result_info with a Files client from dep_files_client.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
The test_sdk fixture becomes async_client (AsyncNemoClient) and typed
clients are built with from_client. The get_sdk_client override stays
for the job_route_factory routes mounted in the same test app. No
assertions change.

require_workspace_access derives AsyncWorkspacesClient from the

…routes

The hello route derives AsyncWorkspacesClient from the request-scoped
AsyncNemoClient and drops the TYPE_CHECKING import of AsyncNeMoHelix.

The openapi test calls the TestClient directly instead of going through
NeMoHelix._client. No assertions change.

Replaces sdk.intake.ingest.otlp.v1.traces.create and sdk.intake.spans.list
with IntakeClient.create_otlp_traces and list_spans. Assertions read
response.data().errors and iterate the paginated spans with items()
instead of spans.data.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
Raw HTTP tests call the TestClient directly instead of NeMoHelix._client,
the messages test derives WorkspacesClient from ClientContext.client, and
the job compiler unit test mocks AsyncNemoClient. No assertions change.
test_workload_workspace_get_task.py stays on NeMoHelix because the task
entrypoint it drives still takes the SDK.

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
The artifact download route derives AsyncJobsClient and AsyncFilesClient
from the request-scoped AsyncNemoClient. The test now patches from_client
on each typed client and asserts the Files client is the one passed to
the result manager factory (previously both slots received the single
client_from_platform mock).

Signed-off-by: Max Dubrinsky <mdubrinsky@nvidia.com>
Analysis run routes derive AsyncAgentsClient and AsyncModelsClient from
the request-scoped AsyncNemoClient, and submit_analysis_run takes those
typed clients instead of an AsyncNeMoHelix. The scheduler controller
adapts its service-principal SDK into the typed clients at the call site.
Route tests patch from_client on the typed client classes instead of
client_from_platform; no assertions change.

get_files_client derives AsyncFilesClient from the request-scoped
AsyncNemoClient. files_client_for and its swallow-and-return-None wrapper
go away since deriving a typed client from the platform client cannot
fail the way adapting a foreign SDK could.

Sync counterpart of get_nemo_client: a stub in nemo_helix_plugin
dependencies, DependencyProvider.get_request_scoped_sync_nemo_client built
from nhx.common.client_factory.get_nemo_client on the provider's sync
transport, the override registration in setup_dependencies, and the
re-export from nhx.common.service.

add_function_routes resolves sdk from get_sync_nemo_client and async_sdk
from get_nemo_client, matching what the local CLI path already passes.
Data Designer preview functions annotate NemoClient/AsyncNemoClient, and
the retrieval corpus and secret helpers accept the platform client
protocols since they only adapt the handle into typed clients.

…lt-storage tests

client_with_s3_default is now a NemoClient, whose .files is a FilesClient
