- Around line 90-92: Update the waiting path in retireEndpointDemand so an
existing EndpointDownloadDemand with consumers not yet retired requests a timed
requeue instead of returning a reconcile error. Preserve error returns for
consumer-reader, inventory, validation, and status-patch failures, and update
both BaseModel and nearby reconcilers that join retireEndpointDemand results so
the wait becomes a requeue without error.

model eligibility with current positive Endpoint demand, and use it for add,
replay, queued-task, and newly-eligible update enqueue decisions, including both

Do not return the retirement wait as a reconcile error.
When EndpointDownloadDemand exists and demandConsumersRetired returns false, nil, retireEndpointDemand returns an error. Both reconcilers join that error with the model reconcile error. This sends the expected retirement wait through controller error backoff and logs it as an error on each reconcile.
Return a timed requeue for the waiting state. Continue returning errors for consumer-reader, inventory, validation, and status-patch failures.

Apply the Endpoint demand gate to every download path.
modelEligible checks only node and scope eligibility. An Endpoint model with no current positive demand therefore passes add and replay checks and is queued. CurrentTaskAllowed also permits queued Download and DownloadOverride tasks through that unchecked predicate.
The update handlers do not observe this field either. They compare only modelEligible, storage download policy, labels, annotations, and download override inputs. A later positive demand update can therefore fail to enqueue a required download.
Keep demand selection separate from node eligibility. Do not use it for cache deletion.

What this PR does
This PR adds an opt-in model-download scope contract that lets an external controller restrict downloads to selected node pools using the existing model storage selectors and affinity.
The external controller decides which pools need a model. Model-agent validates that projection and downloads the model only when the node is eligible.
This keeps endpoint and pool orchestration outside model-agent: no endponit-watches, customer-specific logic, or download-priority scheduler are introduced.
Why we need it
Eagerly downloading every eligible model onto newly provisioned, dedicated nodes can consume significant disk space and network bandwidth, delaying downloads needed for serving.
Controll-projected eligibility allows deployments to download only the models needed by selected pools while retaining ordinary-node download behavior. This implementation is generic: it dow not hard code any BYOR identifiers, environments or pool names.
Changes
Model-agent scope validation
PR adds two optional flags (both empty by default:
Equivalent environment variables:
When configured:
noteSelector/nodeAffinityconstraints and the controller'smodels.ome.io/download-scopeannotationQueued-task safety
Download and cleanup tasks are revalidated against current model identity and eligibility before execution.
This protects against:
Existing download, reuse, cancellation, and cleanup machinery remains in place.
Compatibility and safe download-state retirement
PR also adds compatibility schema fields and retirement handling for existing endpoint-demand observations.
For both
BaseModelandClusterBaseModel, retirement:Manager readiness
Manager readiness now waits for registered controller sources to synchornize. STandby replicas can become ready without acquiring leadership or starting reconciliation.
The change separates controller-source readiness from liveness and avoids maintaining a second, potentially incomplete dependency list.
Generated deepcopy code, OpenAPI schemas, CRDs, Helm schemas, and manager RBAC are updated accordingly.
