Cowork tasks
Rewrite what the company's work asks for
Requires a user session with multiplayer_tasks.update or the existing application_themes.update permission. Replaces the title and the request together, as the ticket’s editor saves them; surrounding whitespace is dropped from the title. Work a run holds keeps the request that run was given, so it is refused until the run ends or is cancelled, and work still carrying a finished run’s result is refused until a status decision lets go of that run, so the result is never shown as the answer to a request it was not given. The edit is recorded in the task’s history: the title’s change, and that the request was rewritten (a description entry of [null, null], never the text). The version the client observed is compared with the stored one, so an edit made against a stale view is refused and answered with the current task instead of merged. Once work has been edited, a creation retry for its identity is refused as a reused identity. Work in another company, deleted work, and an unknown id all answer the same not-found; work deleted after that read and before the edit lands answers 410.
