Reassigning a task only rewrites a column on `tasks`, so nothing records who moved it or when. Add an append-only event table alongside the other task-child tables: one row per change, carrying the actor (user or agent) and the ids the slot moved between. `type` is a plain text column typed through `.$type<>()`, so onboarding a new event kind — status, priority, … — is a type-only change rather than a migration. `visibility` mirrors the parent task the same way `task_topics` / `task_comments` do, so ownership filters without joining back to `tasks`, and the public → private demotion cascade covers it too.
