Who is it for?
Decision note
Rebuilt from the original export under the complete V411 factual-source-verification workflow. Preview only. Apply remains blocked until Failures = 0, Warnings = 0, Unmapped = 0, Missing = 0, all explicit clears are reviewed, image import is disabled or V380 accepts the asset, one representative WordPress edit screen is compared with the export and proposed row, and a post-Apply zero-change Preview is completed.

- Runs locally and on Kubernetes
- Managed Anyscale option is available
Limitations
Serving reliability and latency depend on model code, resources, autoscaling, networking, and dependencies.
Teams must test failure recovery, concurrency, request validation, observability, security, and model licenses.
