In `@packages/nmp_common/src/nmp/common/client_factory.py`:
- Line 140: Update the credentialed request flow around the url_resolver lambda
to reject service endpoints using http:// before transmission, while preserving
Unix domain socket routes as a separate local transport case. Use the existing
endpoint or route classification symbols to distinguish encrypted HTTPS routes
from UDS routes, and fail before credentials are sent.
In `@packages/nmp_common/src/nmp/common/sdk_factory.py`:
- Line 39: Update the client-selection branches in the SDK factory so
configuring base_url does not replace the endpoint client when service routes
are configured; preserve the transport used by _prepare_url for UDS routing, or
explicitly bypass routing for base_url requests. Add synchronous and
asynchronous coverage for base_url combined with a UDS service route.
In `@services/core/files/src/nmp/core/files/api/endpoint_helpers.py`:
- Around line 306-310: Update the headers construction near
auth_client.principal to use auth_client.principal.effective_principal,
preserving the effective principal ID, groups, and email in the delegated
request headers. Retain the internal request headers and service principal
fields, but ensure delegated group-based authorization continues to receive the
effective principal claims.

In `@packages/nmp_common/src/nmp/common/platform_endpoint.py`:
- Around line 88-96: Preserve caller-configured default query parameters when
constructing the routing wrappers: pass http_client.params into both the
synchronous ImmutableDefaultHttpxClient in the relevant platform endpoint flow
and the corresponding async_sdk_http_client wrapper. Keep the existing client
settings and transport behavior unchanged.
- Around line 208-211: Update the local-service branch around
parse_platform_endpoint to retain and pass the original configured service name
to platform_config.get_service_url instead of the normalized name, ensuring
exact-key lookup for entries such as my_service while preserving normalized
matching.
- Around line 189-192: Update the service endpoint construction around
_service_route_names and resolve_service_endpoint to skip environment-derived
service URLs with unsupported or invalid values, while preserving errors for
invalid explicit service_discovery and base endpoints. Ensure unrelated
NMP_*_URL variables cannot prevent SDK client construction.
In `@packages/nmp_common/src/nmp/common/sdk_factory.py`:
- Around line 205-210: Update both workload-identity SDK construction paths,
including _WorkloadIdentityRoutedNeMoPlatform and the async counterpart, to pass
the resolved endpoint’s sync_sdk_http_client() and async_sdk_http_client()
respectively, ensuring UDS-routed service URLs use the endpoint routing clients.
- Around line 400-402: Update the merged_headers construction in the SDK factory
to copy the complete base_sdk.default_headers mapping, including Omit sentinel
values, instead of filtering to string values. Preserve the existing header
merge behavior so NeMoPlatform.copy(set_default_headers=...) continues honoring
explicitly omitted headers.
In `@packages/nmp_common/tests/test_platform_endpoint.py`:
- Around line 177-182: Update _url_for_endpoint to preserve the configured
endpoint path prefix from connect_base_url when constructing routed request
URLs, while retaining the existing scheme, host, port, and query behavior.
Adjust the routing test expectation to include /entities-prefix before
/apis/entities/v2/workspaces.

In `@packages/nmp_common/src/nmp/common/service/base.py`:
- Around line 502-503: Update the route-tagging logic to traverse effective
route contexts via iter_route_contexts() rather than iterating rc.router.routes
directly, then append RouterConfig.tag to each untagged context's original_route
when it is an APIRoute. Add a regression test covering OpenAPI generation for an
untagged APIRoute nested in an included router.
In `@packages/nmp_common/tests/jobs/conftest.py`:

exposes the instance-level jobs attribute before accessing m.jobs; preserve the
existing AsyncMock behavior and avoid changing production code.

_EffectiveRouteContext and _IncludedRouter imported by the test module are
available, or replace those private imports with supported public FastAPI APIs.

TL;DR
This refactors platform SDK and
NemoClientconstruction so generated and plugin clients use endpoint-owned, immutable HTTP clients with service-aware routing instead of shared mutable clients or module-level test fallbacks.What changed
/apis/<service>/...requests to the matching TCP or UDS service endpoint while leaving non-API paths and already-service-specific URLs alone.NeMoPlatformsubclasses and preserves routing throughcopy()/with_options(), including typed plugin client adapters, instead of attaching request routing to individual SDK instances._test_http_clientfallbacks. In-process clients are passed explicitly, request-scoped SDKs are reused for files/jobs flows, and jobs log filtering normalizesjob_attemptto a string.Why
The previous lifecycle mixed per-request SDK state with reusable HTTP client state, which made routing and auth propagation harder to reason about across production, service-discovery, UDS, plugin adapter, and in-process test contexts. Owning routing at the endpoint/SDK layer keeps transport configuration stable while allowing per-request headers and scoped SDK options to stay on the SDK instances that need them.
