TL;DR

Core auth, access-key, and IAM client surfaces now live in source-owned nemo_platform_plugin clients instead of Stainless-generated SDK resources. The generated SDK and generated CLI no longer expose those auth resources, and access-key lifecycle validation now avoids sending bearer tokens over unsafe transport settings.

What Changed

  • Added source-owned typed auth endpoints, response models, and sync/async authentication clients in nemo_platform_plugin.
  • Exposed source-owned auth, access_keys, and iam resource clients from the plugin NemoClient / AsyncNemoClient convenience surface.
  • Removed auth, access-key, and IAM resources from Stainless configuration and regenerated SDK output, including generated resource clients, generated auth-owned types, generated SDK resource tests, and stale API index entries.
  • Updated generated CLI configuration and output so source-owned auth/access-key/IAM API commands are not generated.
  • Extended SDK tooling so source-owned resources and auth bootstrap utility endpoints are excluded cleanly while schemas still referenced by generated resources remain available.
  • Added API index cleanup to the SDK post-generation flow so deleted source-owned artifacts do not leave stale type imports or resource links behind.
  • Repointed platform auth lifecycle code and auth/authorization scenario checks to the source-owned plugin clients.
  • Hardened access-key lifecycle validation so bearer-token validation only targets HTTPS, Unix socket, or loopback HTTP endpoints and refuses redirect-following validation clients.

Reviewer Notes

The generated nemo_platform.NeMoPlatform SDK intentionally no longer exposes Stainless-backed auth, access_keys, or iam resources. Code that needs those APIs should use the source-owned plugin clients, including client_from_platform(..., AuthenticationClient), AccessKeysClient, or IAMClient as appropriate.

📝 Walkthrough

Walkthrough

The change adds platform authentication clients and shared response models, migrates access-key validation, enforces endpoint safety, marks auth-related resources as source-owned, cleans generated SDK artifacts, and removes IAM CLI commands.

Changes

Authentication and SDK ownership migration

Layer / File(s) Summary
Authentication contracts and client access
packages/nemo_platform_plugin/src/nemo_platform_plugin/auth/*, packages/nemo_platform_plugin/src/nemo_platform_plugin/client/client.py, packages/nemo_platform_plugin/tests/auth/*, packages/nemo_platform_plugin/tests/client/*
Adds bearer-token types, GET and POST endpoints, synchronous and asynchronous clients, and auth, access-key, and IAM convenience properties.
Access-key validation migration
packages/nmp_common/src/nmp/common/auth/access_key_lifecycle.py, services/core/auth/src/nmp/core/auth/api/v2/*, tests/agentic-use/auth-authorization-cli*/tests/test_outputs.py
Uses shared response models and AsyncAuthenticationClient for validation. Updates error handling and IAM response iteration.
Endpoint authorization and redirect controls
packages/nmp_common/src/nmp/common/platform_endpoint.py, packages/nmp_common/tests/auth/*, packages/nmp_common/tests/test_platform_endpoint.py
Adds redirect controls and rejects remote cleartext authorization endpoints before token transmission.
Generated SDK exclusion and cleanup
tools/nemo-platform-sdk-tools/src/nemo_platform_sdk_tools/sdk/*, tools/nemo-platform-sdk-tools/tests/sdk/*
Marks auth, access-key, and IAM resources as source-owned, excludes utility schemas, and removes unavailable API index imports and links.
IAM CLI removal
packages/nemo_platform_ext/src/nemo_platform_ext/cli/commands/api/*, packages/nemo_platform_ext/tests/cli/test_app.py
Removes IAM CLI modules and verifies that auth, access-key, and IAM entries are absent from the API manifest.

In `@packages/nmp_common/src/nmp/common/auth/access_key_lifecycle.py`:
- Line 103: Update parse_platform_endpoint and the credential-bearing client
using the Authorization header to reject remote http:// endpoints, while
permitting only a clearly trusted local-only exception; preserve unix://
support. Also disable or validate redirects so bearer-token requests cannot be
redirected to HTTP.

In
`@tools/nemo-platform-sdk-tools/src/nemo_platform_sdk_tools/sdk/core/openapi.py`:
- Line 174: Update calculate_sdk_excluded_schema_names() to subtract the schema
names returned by calculate_schema_to_endpoints() from the excluded set before
returning it, so schemas referenced by generated paths remain available. Add a
regression test covering overlap between SDK-excluded and generated paths,
rather than relying on the existing AuthContext test.
