Confidence Score: 5/5

The PR appears safe to merge, with the behavior changes matching established workspace chat patterns and covered by focused regression tests.

Summary

• Reuses intent-aware chat-history prefetching for expanded and collapsed organization navigation.
• Remounts organization conversation state when the organization or routed chat changes.
• Keeps existing messages and the composer visible while background history loading continues.
• Extracts guarded composer autofocus into a shared hook and adds regression coverage.
