v0.53.0

Minor Changes

• Remove the deprecated ok ui command and the sibling UI spawn machinery. Plain ok start has served the editor UI, API, and MCP on one port since the single-listener flip, and the Desktop attaches via server.lock v2 — the two-process sibling model is gone.

  • ok ui no longer exists. If you were running it directly, run ok start instead; if a tool spawned it for you (an old .claude/launch.json entry), re-run ok init or delete the stale entry — current OK never scaffolds one.
  • ok start drops --ui-port (the worktree-preview sibling recipe) and no longer auto-spawns a UI sibling in any mode. --only ui --server-url (the explicit split-mode proxy) still works but now prints a deprecation notice; it will be removed together with ui.lock in a later release.
  • The clone/open flow that previously spawned ok ui next to a headless server now resolves the redirect from server.lock directly. A server started with --only server reports "no UI mounted — restart with plain ok start" instead of spawning a sibling.
  • Operator and agent hints that pointed at ok ui (404 pages, MCP preview messages, CLI errors, config-migration redirects) now point at ok start.

  ui.lock is still written and read for compatibility; it retires in a follow-up release.
