Restored transcripts can still present stale running state while their final markdown and tool output continue to reflow. Resize-driven auto-follow now stays enabled only for live resizable output, so readers can scroll up after completion while active streams still remain pinned. Constraint: Old H5 sessions can reconnect with stale non-idle UI state even when the transcript has an end_turn. Rejected: Disable resize following entirely | active H5 streaming would regress when rendered content grows after tokens arrive. Confidence: high Scope-risk: narrow Directive: Do not broaden ResizeObserver auto-follow without a restored completed-session regression test. Tested: cd desktop && bun run test -- MessageList.test.tsx Tested: cd desktop && bun run lint Tested: cd desktop && bun run build Tested: Browser smoke on session 85862799-ec6b-43d0-b3b8-6e9fd9130954 kept scrollTop at 320 after content resize.
