"""Configure the immutable model source registry for governed snapshots.

The phase-2 seed intentionally registered model artifacts as unknown. Runtime
|
|
model provenance now records exact immutable snapshots, so the server-owned
|
|
registry must advertise that configured capability. The write guard is only
|
|
disabled for this narrowly-scoped, versioned migration and is restored in the

|
same transaction.
