Parallel shipping plans need current branch and deployment evidence

Parallel shipping work should be partitioned by release target and shared-file ownership, then integrated through one release owner. Recheck current PR state, conflicts, deployed telemetry and workflow state before scheduling promotion: a historical chat is useful context but cannot establish present readiness. Treat code merged, image built, deployment completed and customer outcome verified as separate evidence. This applies to multi-branch services with overlapping runtime, telemetry and CI changes; it does not imply that every ready-looking PR should be merged or that passing unit checks certify live behavior.
