What probably matters to youSection of the release

Only mentioned when the live-edit gate is open and the schema supports operations.

What

The artifact tool gains a sync action next to live-edit. It pushes edits you made to a local copy of an already-published artifact page up to the page, with those edits going live immediately, and pulls other people's changes back down into your file. It is only mentioned in the tool prompt when the live-edit gate is open and the tool schema carries operations support, a server-driven condition.

Details
  • Input is validated by a live-document module; if that module is absent the call fails with "sync is not available in this build".
Evidence

Push the edits made to the working copy of an already-published artifact page to the page, and pull others' changes into the file — the pushed edits go live immediately

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
