364-365: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winDo not reconcile orphans from a partial deployment snapshot.
If one status query or paginator fails, this branch returns deployments from the other statuses.
async_controller_stepthen treats that partial set as complete and can delete valid backend deployments as orphans.Return a completeness result. Skip
reconcile_orphanswhen any status listing fails. Add a test that injects one failed status query and asserts that orphan reconciliation does not run.🤖 Prompt for AI Agents

TL;DR
Removes the core models controller's dependency on Stainless-generated model and inference resource types by routing controller operations through the
nemo_platform_plugintyped clients instead. The OpenAPI spec, generated SDK, Studio UI, and lockfile output are unchanged.Details
This refactors the models controller, provider reconciler, deployment reconciler, and deployments-plugin backend path to use
nemo_platform_pluginmodel, virtual-model, and inference-gateway clients for reads, writes, status updates, and provider discovery. The controller now works with plugin-owned request/response types and enum values rather than importing model resources from the generated SDK.To support that migration, the plugin package gains a narrow typed Inference Gateway provider client for
GET /v1/models, local model reference helpers that replace the old generated-model convenience imports, and an explicit virtual-model delete query parameter type for optimistic cleanup. Provider discovery keeps the same OpenAI-compatible/v1/modelsbehavior while decoding dynamic gateway responses through the plugin client layer.The tests move onto the same typed client surface used by the controller. Integration fixtures now create, update, list, and delete providers, deployment configs, deployments, and virtual models through
ModelsClient, with focused coverage for the new inference-gateway client and updated reconciliation/auth flows.
