Roll back an adapter
Point the alias back at the previously served adapter model (previous_model_id) under a fresh version. Status returns to ‘attaching’ until every serving replica reports the rollback target loaded: usually immediate when the old weights are still resident, otherwise after a re-download.

Path Parameters
Deployment ID
The adapter's public alias
Response
The alias now serves the previous model at version+1, status 'attaching' until the fleet converges
A LoRA adapter attached to a multi_adapter deployment.
Always "deployment_adapter".
Attachment ID (ada_...).
The deployment (fleet) this adapter is attached to.
Public routing alias the adapter serves under.
The custom model currently served under this alias.
Monotonic version counter; incremented on every flip/rollback.
vLLM-facing name ("{serve_name}@v{version}-{tag}", tag derived from model_id): never reused for different weights.
attaching | active | detaching. 'active' means every serving replica reports the current version loaded.
Attachment creation time.
Last status/version change time.
Per-serving-replica load state for the CURRENT internal_name.

The previously served model, if any (the rollback target).
Mid-flip only: the staged new version awaiting fleet convergence.
Mid-flip only: the staged version's internal name.
The platform model version (model_versions.id) currently served under this alias, when the model belongs to a lineage.
Mid-flip only: the platform model version staged by a production
alias move; the fleet cuts over to it automatically on convergence.
