Scope creep pattern: Workers are consistently combining unrelated changes into single PRs. Ticket #72 (column rename) included PR #56 changes (Artifact/CodeDiff removal). Ticket #60 (test coverage) included infrastructure changes (WebSocket isolation, SolidCable setup, config files). This indicates a process issue where workers may be batching changes for efficiency, but it violates the "one PR per ticket" principle needed for proper review.
