Artifact patch edits can be tagged with a request class, and their server settings are parsed more strictly

What

Artifact patch edits answer some edit requests about an artifact page by editing its file directly. The feature stays switched off unless the server turns it on, and its server-side settings changed.

• The settings now also read sideCallClass. Only the exact value side_reply is kept; anything else is ignored. The kept value is sent as requestClass on the artifact_patch_edit model call.
• Parsing is stricter. The feature is on only if enabled is true and models is either missing or a valid, non-empty list of names. An invalid models value now switches the feature off, where before it fell back to a default list. A missing models falls back to ["claude-opus-5-5"].
• Artifact publishing now records motion_type when one is present.
• The "Deployment display name" setting is marked hotApplied, meaning a change pushed by the administrator takes effect without restarting.

Why

Nothing visible changes unless the server enables artifact patch edits. If it does, a malformed model list now turns the feature off rather than quietly applying it to default models.
