Replace the preview-wide loading indicator with section placeholders so Activity remains available while pull request and Seer data load.
Keep pull request and Autofix loading states independent so an unfinished prefetch does not block Activity or other cached issue content. Refs ISWF-3354
Start group, pull request, and Autofix queries immediately on hover or focus. Keep group content available while secondary preview requests are pending. Refs ISWF-3354
Debounce preview prefetches for 100 ms while keeping every query independent. Replace the group-level spinner with a structured preview skeleton. Refs ISWF-3354

Keep the existing hover-only debounce while warming the additional preview requests independently. Restore the original group loading state and retain only section-level progressive rendering. Refs ISWF-3354
Reuse the shared group and organization parameters across preview queries and remove unused response fixtures from requests that intentionally remain pending. Refs ISWF-3354
Keep the group prefetch at 100ms, delay secondary requests to 300ms, and only prefetch Autofix data when the issue supports it. Avoid retries for secondary hover requests and omit the pull request placeholder when no section is known to exist. Refs ISWF-3354
Render the selected inbox group while the full group and secondary preview requests continue loading independently. Refs ISWF-3354
Render only the safe group summary from inbox list data, then mount the full preview after the group detail request completes. Refs ISWF-3354
Restore the existing preview rendering and selection flow. Keep this change limited to warming the additional Pull Request and Autofix query caches. Refs ISWF-3354
Use one 200 ms hover delay before warming the group, Pull Request, and eligible Autofix queries. Refs ISWF-3354

Please check back later.
Inbox hover prefetching now waits 200 ms, then warms the existing group query, linked Pull Requests, and Autofix setup and state for eligible issues at the same time. Speculative requests do not retry. The preview's existing rendering and selection behavior is unchanged.
The additional queries reuse the same option factories as their consumers. Autofix setup and state use a 30-second stale window so the warmed cache is consumed when the preview mounts; polling, explicit refetches, and mutation invalidation continue to refresh them.
