v0.60.0

Minor Changes

• Retire the ui.lock sibling advertisement and bump the cross-process protocol to v2.

  A server that serves the editor now advertises the UI through a single record — its own server.lock carrying a ui capability — instead of writing a separate ui.lock. Preview-URL resolution, the clone→open redirect, and ok status / ps / stop / clean all read that one record. For one release of upgrade goodwill, ok stop still SIGTERMs a lingering pre-migration ok ui holder and ok clean still prunes a leftover ui.lock.

  The split-mode ok start --only ui --server-url proxy is removed: plain ok start serves the editor, API, and MCP on one port. ok start --only server stays for headless and container use.

  The cross-process protocol version is now 2 — the deliberate break that marks this release incompatible with older peers. A previous-stable desktop attaching to a v2 server classifies the mismatch and surfaces the version-drift prompt (with a restart action) through the existing desktop attach-drift check, instead of silently running on against an incompatible server.
